ABSTRACT

ABSTRACT BACKGROUND: Postoperative nausea and vomiting (PONV) is a common complication from general anesthesia that impacts on postoperative recovery. OBJECTIVE: To evaluate prophylactic rewarming following general anesthesia, so as to decrease the incidence of PONV among patients undergoing laparoscopic hysterectomy. DESIGN AND SETTING: Prospective randomized clinical study at a hospital in China. METHODS: Sixty-two patients were randomly assigned into two groups. The forced air warming (FAW) group received pre-warmed Ringer's solution with FAW until the end of surgery. The control group received Ringer's solution without FAW. The pre-warmed Ringer's solution was stored in a cabinet set at 40 °C. The FAW tube was placed beside the patient's shoulder with a temperature of 43 °C. RESULTS: Sixty patients completed the study. The FAW group showed significant differences versus the controls regarding temperature. At 6, 24 and 48 hours postoperatively, the incidences of PONV were 53.3%, 6.7% and 3.3% in the FAW group versus 63.3%, 30% and 3.3% in the controls. VAS scores were significantly lower in the FAW group than in the controls at 24 hours (P= 0.035). Forty-item questionnaire total scores in the FAW group were significantly higher than in the controls. The physical independence and pain scores at 24 hours and emotional support and pain scores at 48 hours in the FAW group were higher than in the controls (P < 0.05). There was no difference in hemodynamics or demographics between the two groups (P > 0.05). CONCLUSIONS: Prophylactic rewarming relieved PONV and improved the quality of postoperative recovery.

ABSTRACT

INTRODUCCIÓN: Actualmente la cirugía laparoscópica es el gold standard de la mayoría de las cirugías ginecológicas benignas. Se estima una tasa de complicaciones en cirugía ginecológica por laparoscopía de 3.2 por 1000 pacientes, donde alrededor del 50% ocurren al momento de la primera entrada. Existen numerosas clasificaciones de las complicaciones quirúrgicas, entre ellas, la clasificación Clavien-Dindo se centra en el tratamiento postquirúrgico y tiene como objetivo unificar criterios y hacerlas comparables entre distintos centros. OBJETIVO: Describir las complicaciones en cirugía laparoscópica ginecológica en el Hospital Padre Hurtado, destacando el subgrupo de primera entrada y su clasificación Clavien-Dindo. METODOLOGÍA: Cohorte retrospectiva que incluyó a todas las pacientes operadas por laparoscopía en el pabellón de ginecología del Hospital Padre Hurtado desde el año 2014 al 2017. Se utilizó el software SPSS statistics v25, con prueba X2 para el análisis de las variables no paramétricas y t de Student para las variables paramétrica, considerando una significación estadística con p<0,05. RESULTADOS: De las 513 cirugías laparoscópicas ginecológicas realizadas en el período evaluado, sólo el 4,3% del total de las pacientes tuvieron complicaciones. De éstas, un 9% fueron de primera entrada, y en todos los casos fueron complicaciones menores o Clavien-Dindo I y II. Hubo 2 complicaciones Clavien-Dindo >III B, lo que correspondió a un 0,39%. CONCLUSIÓN: En nuestro grupo hubo una baja incidencia de complicaciones quirúrgicas y de primera entrada lo que es comparable con otras series publicadas.

ABSTRACT

INTRODUCCIÓN Y OBJETIVOS: Están demostradas las ventajas de la cirugía laparoscópica para el paciente en términos de dolor, rápida recuperación y precisión quirúrgica, sin embargo, no existen estudios nacionales respecto al impacto en los cirujanos. El objetivo de este trabajo es realizar un estudio prospectivo de evaluación ergonómica de ginecólogos que operan cirugía laparoscópica. MÉTODOS: Se utilizaron métodos de evaluación específica por ergónomo experto y percepción de los participantes. Se evaluaron, carga global de trabajo (NASA-tlx), carga bio-mecánica (REBA) y la percepción de molestias músculo-esqueléticas (Escala de Discomfort Corporal). Se recogieron datos personales y de la cirugía, para explorar la existencia de dificultades técnicas. RESULTADOS: 86,7% de los ginecólogos evidenciaron altos niveles de carga global de trabajo, siendo las variables esfuerzo y rendimiento, las de mayor puntaje. El nivel de riesgo bio-mecánico, fue catalogado como medio en la totalidad de la población. 60% manifestó discomfort corporal durante la cirugía. En cuanto a las dificultades técnicas, el efecto fulcrum estuvo presente en el 46% de los cirujanos, el mismo porcentaje tuvo síntomas de ojo seco. El 68% alguna vez accionó el pedal equivocado y ha sentido parestesia del pulgar. CONCLUSIONES: La cirugía laparoscópica ginecológica, presenta una elevada carga global de trabajo. El ginecólogo percibe un importante discomfort corporal y algunas dificultades técnicas. Es necesario incorporar medidas ergonómicas, para minimizar y/o disminuir los factores de riesgo mental y físicos, y así prevenir el desgaste precoz y lesiones a futuro en los cirujanos.


INTRODUCTION AND OBJECTIVES: Laparoscopic surgery had demonstrated advantages such as less pain, rapid recovery and surgical precision. There are no national data regarding the impact on surgeon's health. This is a prospective study on ergonomic evaluation and laparoscopic surgery performed by gynecologists. METHODS: Specific evaluation methods were used such as Global workload (NASA-tlx), bio-mechanical load (REBA) and the perception of musculoskeletal discomfort (Body Part Discomfort Scale). Personal opinions and surgery data were collected to explore the existence of technical difficulties. RESULTS: 86.7% of gynecologists cataloged surgery as high level of global workload. Effort and performance variables were most important. Bio-mechanical risk level was classified as medium in the entire population. 60% showed body discomfort during surgery. Regarding technical difficulties, fulcrum effect was present in 46% of surgeons, the same percentage had dry eye symptoms. 68% have a pedal error activation during surgery and felt paresthesia of the thumb. CONCLUSIONS: Gynecological laparoscopic surgery has a high overall workload. The gynecologist perceives an important body discomfort and some technical difficulties. It is necessary to incorporate ergonomic measures, to minimize and / or reduce mental and physical risk factors, and thus prevent early wear and future injuries in surgeons.

ABSTRACT

Resumen La primera colectomía laparoscópica se realizó hace casi 30 años. La adopción como estándar de tratamiento ha sido lenta, a pesar de compartir los beneficios de la cirugía con invasión mínima, como el menor dolor, estadía hospitalaria y recuperación precoz. Esto se explica por el temor generado por reportes iniciales que señalaban la aparición de implantes en los sitios de inserción de los trocares y las dudas sobre la seguridad oncológica. Distintos ensayos clínicos aleatorizados finalmente confirmaron su seguridad y eficacia en el tratamiento del cáncer de colon con resultados comparables a la cirugía abierta. La curva de aprendizaje prolongada, dada por la complejidad técnica, ha incentivado el aprendizaje supervisado por un entrenador experto en el contexto de programas de formación de subespecialidad. Nuestro objetivo es realizar una revisión de los resultados a corto y largo plazo y algunas consideraciones generales y perspectivas futuras.


The first laparoscopic colectomy was performed almost 30 years ago, its expansion has been slow and it did not have the explosive development that laparoscopic cholecystectomy and appendectomy had, despite sharing its benefits such as lower pain, hospital stay and early recovery. This is explained, in part, by the initial fear of implants at trocar sites and the lack of oncological safety. Randomized clinical trials confirmed the safety and efficacy of laparoscopic surgery with short-term and oncological results, comparable to open surgery. The slow learning curve, given by technical complexity, has encouraged learning supervised by an expert coach in the context of subspecialty training programs. Our aim is to review the short-term and oncological results, some general considerations and future perspectives.

ABSTRACT

ABSTRACT Background: Extended vertical gastrectomy is a variation of the vertical gastrectomy technique requiring studies to elucidate safety in relation to gastroesophageal reflux. Aim: To analyze comparatively vertical gastrectomy (VG) and extended vertical gastrectomy (EVG) in rats with obesity induced by cafeteria diet in relation to the presence of reflux esophagitis, weight loss and macroscopic changes related to the procedures. Methods: Thirty Wistar rats were randomized into three groups, and after the obesity induction period by means of a 28-day cafeteria diet, underwent a simulated surgery (CG), VG and VGA. The animals were followed up for 28 days in the post-operative period, and after euthanasia, the reflux esophagitis evaluation was histopathologically performed. Weight and macroscopy were the other variables; weight was measured weekly and the macroscopic evaluation was performed during euthanasia. Results: All animals presented some degree of inflammation and the presence of at least one inflammation criterion; however, there was no statistically significant difference in the analysis among the groups. In relation to weight loss, the animals in CG showed a gradual increase during the whole experiment, evolving to super-obesity at the end of the study, while the ones with VG and EVG had weight regain after the first post-operative period; however, a less marked regain compared to CG, both for VG and EVG. Conclusion: There is no difference in relation to reflux esophagitis VG and EVG, as well as macroscopic alterations, and both techniques have the ability to control the evolution of weight during postoperative period in relation to CG.


RESUMO Racional: A gastrectomia vertical ampliada é uma variação da técnica da gastrectomia vertical, necessitando de estudos a fim de elucidar a segurança em relação ao refluxo gastroesofágico. Objetivo: Analisar comparativamente gastrectomia vertical (GV) e gastrectomia vertical ampliada (GVA) em ratos com obesidade induzida por dieta cafeteria em relação à presença de esofagite de refluxo, perda de peso e alterações macroscópicas relacionadas aos procedimentos. Método: Trinta ratos Wistar foram randomizados em três grupos, e após período de indução de obesidade por meio de dieta cafeteria de 28 dias, foram submetidos a operação simulada (grupo controle GC), gastrectomia vertical (grupo GV) e gastrectomia vertical ampliada (grupo GVA). Os animais foram acompanhados por 28 dias no pós-operatório e, após a eutanásia, foi realizada a pesquisa de esofagite de refluxo através de avaliação histopatológica. Peso e avaliação macroscópica foram as outras variáveis de estudo, sendo o peso aferido semanalmente e a avaliação macroscópica no momento da eutanásia. Resultados: Todos os animais apresentaram algum grau de inflamação e a presença de ao menos um critério de inflamação, porém, não houve diferença estatisticamente significante na análise entre os grupos. Em relação à perda de peso, os animais do GC apresentaram aumento gradativo durante todo experimento evoluindo para super-obesidade ao término do estudo, enquanto os dos grupos GV e GVA tiveram reganho de peso após a primeira semana do pós-operatório, porém, reganho menos acentuado se comparável ao GC, tanto para GV quanto para GVA. Conclusões: Não há diferença em relação à esofagite de refluxo entre GV e GVA, bem como em relação às alterações macroscópicas. Ambas as técnicas têm capacidade de controlar a evolução do peso no pós-operatório em relação ao grupo controle.

ABSTRACT

ABSTRACT Background: Erosion and migration into the esophagogastric lumen after laparoscopic hiatal hernia repair with mesh placement has been published. Aim: To present surgical maneuvers that seek to diminish the risk of this complication. Method: We suggest mobilizing the hernia sac from the mediastinum and taking it down to the abdominal position with its blood supply intact in order to rotate it behind and around the abdominal esophagus. The purpose is to cover the on-lay mesh placed in "U" fashion to reinforce the crus suture. Results: We have performed laparoscopic hiatal hernia repair in 173 patients (total group). Early postoperative complications were observed in 35 patients (27.1%) and one patient died (0.7%) due to a massive lung thromboembolism. One hundred twenty-nine patients were followed-up for a mean of 41+28months. Mesh placement was performed in 79 of these patients. The remnant sac was rotated behind the esophagus in order to cover the mesh surface. In this group, late complications were observed in five patients (2.9%). We have not observed mesh erosion or migration to the esophagogastric lumen. Conclusion: The proposed technique should be useful for preventing erosion and migration into the esophagus.


RESUMO Racional: Com a colocação de tela foi têm sido publicadas erosões e migrações para o lúmen esofagogástrico após correção de hérnia hiatal laparoscópica. Objetivo: Apresentar manobras cirúrgicas que buscam diminuir o risco dessa complicação. Método: Sugerimos mobilizar o saco de hérnia do mediastino e levá-lo à posição abdominal com o suprimento sanguíneo intacto, a fim de girá-lo para trás e ao redor do esôfago abdominal. O objetivo é cobrir a malha colocada sobre a forma "U" para reforçar a sutura da crura haital. Resultados: Realizamos reparo laparoscópico de hérnia hiatal em 173 pacientes (grupo total). Complicações pós-operatórias precoces foram observadas em 35 pacientes (27,1%) e um morreu (0,7%) devido a tromboembolismo pulmonar maciço. Cento e vinte e nove pacientes foram acompanhados por média de 41+28 meses. A colocação da tela foi realizada em 79 desses pacientes. O saco remanescente foi girado atrás do esôfago para cobrir a superfície da tela. Nesse grupo, complicações tardias foram observadas em cinco pacientes (2,9%). Não observamos erosão da tela ou migração dela para o lúmen esofagogástrico. Conclusão: A técnica proposta pode ser útil para prevenir a erosão e a migração para o esôfago de telas na correção de hérnias hiatais.

ABSTRACT

Abstract Purpose To evaluate the analgesic effect of esmolol in patients submitted to laparoscopic gastroplasty. Methods Forty patients aged between 18 and 50 years with American Society of Anesthesiologists (ASA) physical status scores of II and III who underwent gastric bypass were allocated to two groups. Group 1 patients received a 0.5-mg/kg bolus of esmolol in 30 mL of saline before induction of anesthesia, followed by an infusion at 15 µg/kg/min until the end of surgery. Group 2 patients received 30 mL of saline as a bolus and then an infusion of saline. Anesthesia included fentanyl (3 µg/kg), propofol (2-4 mg/kg), rocuronium (0.6 mg/kg), and 2% sevoflurane, with remifentanil if necessary. The following parameters were evaluated: pain intensity over 24h, remifentanil consumption, the first analgesic request, morphine consumption, and side effects. Results Pain intensity was lower in the esmolol group except at T0 (after extubation) and 12h postoperatively. Remifentanil supplementation, recovery time, and postoperative morphine supplementation were lower in the esmolol group. No differences in the time to the first analgesic request or side effects were found between the groups. Conclusion Intraoperative esmolol promotes reductions in pain intensity and the need for analgesic supplementation without adverse effects, thus representing an effective drug for multimodal analgesia in gastroplasty.

ABSTRACT

ABSTRACT Background: Gastroesophageal reflux (GER) is one of the most common indications for conversion of sleeve gastrectomy (LSG) to laparoscopic Roux-en-Y gastric bypass (LRYGBP). Objective evaluations are necessary in order to choose the best definitive treatment for these patients. Aim: To present and describe the findings of the objective studies for gastroesophageal reflux disease performed before LSG conversion to LRYGBP in order to support the indication for surgery. Method: Thirty-nine non-responder patients to proton pump inhibitors treatment after LSG were included in this prospective study. They did not present GER symptoms, esophagitis or hiatal hernia before LSG. Endoscopy, radiology, manometry, 24 h pH monitoring were performed. Results: The mean time of appearance of reflux symptoms was 26.8+24.08 months (8-71). Erosive esophagitis was found in 33/39 symptomatic patients (84.6%) and Barrett´s esophagus in five. (12.8%). Manometry and acid reflux test were performed in 38/39 patients. Defective lower esophageal sphincter function was observed independent the grade of esophagitis or Barrett´s esophagus. Pathologic acid reflux with elevated DeMeester´s scores and % of time pH<4 was detected in all these patients. more significant in those with severe esophagitis and Barrett´s esophagus. Radiologic sleeve abnormalities were observed in 35 patients, mainly cardia dilatation (n=18) and hiatal hernia (n=11). Middle gastric stricture was observed in only six patients. Conclusion: Patients with reflux symptoms and esophagitis or Barrett´s esophagus after SG present defective lower esophageal sphincter function and increased acid reflux. These conditions support the indication of conversion to LRYGBP.


RESUMO Racional: O refluxo gastroesofágico é uma das indicações mais comuns para a conversão da gastrectomia vertical (SG) em gastroplastia laparoscópica em Y-de-Roux (LRYGBP). Avaliações objetivas são necessárias para escolher o melhor tratamento definitivo para esses pacientes. Objetivo: Apresentar e descrever os achados objetivos da doença do refluxo gastroesofágico realizados antes da conversão do SG para o LRYGBP, a fim de apoiar a indicação cirúrgica. Método: Trinta e nove pacientes não respondedores ao tratamento com inibidores da bomba de prótons após SG foram incluídos neste estudo prospectivo. Eles não apresentavam sintomas de refluxo gastroesofágico, esofagite ou hérnia hiatal antes da SG. Endoscopia, radiologia, manometria, monitoramento de pH 24 horas foram realizados. Resultados: O tempo médio de aparecimento dos sintomas de refluxo foi de 26,8+24,08 meses (8-71). Esofagite erosiva foi encontrada em 33/39 pacientes sintomáticos (84,6%) e esôfago de Barrett em cinco (12,8%). A manometria e o teste de refluxo ácido foram realizados em 38/39 pacientes. A função alterada do esfíncter inferior do esôfago foi observada independentemente do grau de esofagite ou esôfago de Barrett. Em todos esses pacientes, foi detectado refluxo ácido patológico com escores elevados de DeMeester e % de tempo pH<4, mais significativo nos com esofagite grave e esôfago de Barrett. Anormalidades radiológicas SG foram observadas em 35 pacientes, principalmente dilatação da cárdia (n=18) e hérnia hiatal (n=11). Estenose gástrica foi observada em apenas seis pacientes . Conclusão: Pacientes com sintomas de refluxo e esofagite ou esôfago de Barrett após SG apresentam função do esfíncter esofágico inferior defeituosa e aumento do refluxo ácido. Esses sintomas e estudos objetivos apoiam a indicação de conversão para LRYGBP.

ABSTRACT

ABSTRACT Background: Laparoscopic surgery has been gradually accepted as an option for the surgical treatment ofgastric cancer. There are still points that are controversial or situations that are eventually associated with intra-operative difficulties or postoperative complications. Aim: To establish the relationship between the difficulties during the execution of total gastrectomy and the occurrence of eventual postoperative complications. Method: The operative protocols and postoperative evolution of 74 patients operated for gastriccancer, who were subjected to laparoscopic total gastrectomy (inclusion criteria) were reviewed. The intraoperative difficulties recorded in the operative protocol and postoperative complications of a surgical nature wereanalyzed (inclusion criteria). Postoperative medical complications were excluded (exclusion criteria). For the discussion, an extensive bibliographical review was carried out. Results: Intra-operative difficulties or complications reported correspond to 33/74 and of these; 18 events (54.5%) were related to postoperative complications and six were absolutely unexpected. The more frequent were leaks of the anastomosis and leaks of the duodenal stump; however, other rare complications were observed. Seven were managed with conservative measures and 17 (22.9%) required surgical re-exploration, with a postoperative mortality of two patients (2.7%). Conclusion: We have learned that there are infrequent and unexpected complications; the treating team must be mindful of and, in front of suspicion of complications, anappropriate decision must be done which includes early re-exploration. Finally, after the experience reported, some complications should be avoided.


RESUMO Racional: A cirurgia laparoscópica tem sido gradualmente aceita como opção para o tratamento cirúrgico do câncer gástrico. Ainda existem pontos controversos ou situações eventualmente associadas a dificuldades intra-operatórias ou complicações pós-operatórias. Objetivo: Estabelecer a relação entre as dificuldades durante a execução da gastrectomia total e a ocorrência de eventuais complicações pós-operatórias. Método: Foram revisados ​​os protocolos operatórios e a evolução pós-operatória de 74 pacientes operados por câncer gástrico, submetidos à gastrectomia total laparoscópica (critérios de inclusão). Foram analisadas as dificuldades intraoperatórias registradas no protocolo operatório e as complicações pós-operatórias de natureza cirúrgica (critérios de inclusão). As complicações médicas pós-operatórias foram excluídas (critérios de exclusão). Para a discussão, foi realizada extensa revisão bibliográfica. Resultados: Dificuldades ou complicações intraoperatórias relatadas corresponderam a 33/74 e destas 18 (54,5%) foram relacionadas com complicações pós-operatórias e seis absolutamente inesperadas. As mais frequentes foram vazamentos da anastomose e do coto duodenal; no entretanto, outras complicações raras foram observadas. Sete foram tratados com medidas conservadoras e 17 (22,9%) necessitaram de re-exploração cirúrgica, com mortalidade pós-operatória de dois pacientes (2,7%). Conclusão: Aprendemos que existem complicações infrequentes e inesperadas; a equipe de tratamento deve estar atenta e diante da suspeita de complicação, decisão apropriada pode incluir uma nova exploração precoce. Finalmente, após a experiência relatada, algumas complicações devem ser evitadas.

ABSTRACT

La gastrectomía vertical laparoscópica es actualmente la cirugía bariátrica más empleada a nivel mundial. Aunque es un procedimiento seguro y efectivo pueden ocurrir complicaciones mayores. En el presente trabajo reportamos el caso de un infarto y absceso esplénico como una rara complicación de esta técnica, que requirió finalmente de esplenectomía como tratamiento definitivo. Caso clínico: Mujer de 22 años con obesidad grado I, a quien se le practicó gastrectomía vertical laparoscópica con buena evolución intrahospitalaria y egreso a las 48 horas. Al 4to día posoperatorio consultó por fiebre, dolor abdominal, taquipnea y taquicardia. Mediante tomografía computada de abdomen se diagnosticó infarto esplénico parcial. Recibió tratamiento médico con remisión inicial de los síntomas, los cuales reaparecieron a la 3era semana. Se reinició el tratamiento médico, esta vez sin respuesta, y con evolución al absceso esplénico. Se decidió esplenectomía como tratamiento definitivo logrando la recuperación completa de la paciente. Conclusión: El infarto esplénico es una complicación infrecuente de la gastrectomía vertical. Su tratamiento inicial es médico, reservando la esplenectomía para los casos que no responden(AU)


Laparoscopic sleeve gastrectomy is currently the most performed bariatric surgery worldwide. Although it is an effective and safe procedure major complications can occur. In the present manuscript we report a case of splenic infarct and abscess as a rare complication of laparoscopic sleeve gastrectomy, finally requiring a splenectomy as a definitive treatment. Case report: A 22 years old woman with grade I obesity underwent laparoscopic sleeve gastrectomy with good hospital evolution and 48 hours discharge. On the 4th postoperative day she return because fever, abdominal pain, tachypnea and tachycardia. By means of a computed tomography a splenic infarct was diagnosed. She received medical treatment with initial remission of symptoms, which reappear at the third week. Medical treatment was restarted, this time without success, and with progression to splenic abscess. We decided a splenectomy as definitive treatment achieving a complete patient recovery. Conclusion: Splenic infarction is a rare complication after sleeve gastrectomy. The treatment is non surgical, reserving the splenectomy for the non responded cases(AU)

ABSTRACT

Abstract Objective To evaluate the impact of systematic laparoscopic skills and suture training (SLSST) on the total laparoscopic hysterectomy intra- and postoperative outcomes in a Brazilian teaching hospital. Methods A cross-sectional observational study in which 244 charts of total laparoscopic hysterectomy (TLH) patients operated from 2008 to 2014 were reviewed. Patient-specific (age, parity, previous cesarean sections, abdominal surgeries and endometriosis) and surgery-related variables (hospital stay, operative time, uterine volume and operative complications) were analyzed in three different time-frame groups: 2008-09 (I-1) - TLHs performed by senior attending physicians; 2010-11 (I-2) - TLHs performed by residents before the implementation of the SLSST program; and 2012-14 (I-3) - TLHs performed by residents after the implementation of the SLSST program. Results A total of 244 TLH patients (mean age: 45.93 years) were included: 24 (I-1), 55 (I-2), and 165 (I-3). The main indication for TLH was uterine myoma (66.4%). Group I-3 presented a decrease in surgical time compared to group I-2 (p=0.010). Hospital stay longer than 2 days decreased in group I-3 compared to group I-2 (p=0.010). Although we observed decreased uterine volume (154.2 cm3) in group I-2 compared to group I-1 (217.8 cm3) (p=0.030), logistic regression did not find any association between uterine volume and surgical time (p=0.103). Conclusion The total operative time for laparoscopic hysterectomy was significantly shorter in the group of patients (I-3) operated after the systematic laparoscopic skills and suture training was introduced in our hospital.


Resumo Objetivo Avaliar o impacto do treinamento laparoscópico sistematizado de habilidades e sutura (TLSHS) nos resultados intra e pós-operatórios da histerectomia laparoscópica em um hospital universitário brasileiro. Métodos Estudo observacional transversal de revisão de 244 prontuários de pacientes submetidas a histerectomia total laparoscópica (HTL) operadas entre 2008 e 2014. Os fatores específicos das pacientes (idade, paridade, cesariana prévia, cirurgias abdominais, e endometriose) e as variáveis relacionadas à cirurgia (tempo de hospitalização, tempo de cirurgia, volume uterino e complicações operatórias) foram analisados em três grupos temporais: 2008-09 (I-1) - HTLs realizadas por médicos experientes; 2010-11 (I-2) - HTLs realizadas por residentes sem TLSHS; 2012-2014 (I-3) - HTLs realizadas por residentes após a implementação do TLSHS. Resultados Um total de 244 pacientes submetidas a HTLs foram incluídas (média de idade de 45,93 anos): 24 operadas no período I1, 55 no I2, e 165 no I3. A principal indicação para HTL foi mioma uterino (66,4%). O grupo I-3 apresentou diminuição no tempo cirúrgico quando comparado ao grupo I-2 (p=0,010). Hospitalização superior a 2 dias diminuiu no grupo I-3 comparado ao grupo I-2 (p=0,010). Apesar de observarmos diminuição no volume uterino dos pacientes do grupo I-2 (154,2 cm3) em comparação com os do grupo I-1 (217,8 cm3) (p=0,030), a regressão logística não revelou associação entre volume uterino e tempo cirúrgico (p=0,103). Conclusão O tempo cirúrgico na HTL foi significativamente menor no grupo de pacientes submetidas à cirurgia após a implantação do TLSHS em nosso hospital.

ABSTRACT

SUMMARY OBJECTIVES Inguinal hernioplasty techniques have been improved since the first hernioplasty. Tension-free techniques that apply synthetic mesh materials, as in the Lichtenstein approach, are the gold standard. Laparoscopic hernioplasty is the strongest alternative to Lichtenstein. The superiority of laparoscopic hernioplasty over Lichtenstein is a major topic of debate. In this study, we aimed to find a conclusion to this debate by comparing our totally extraperitoneal (TEP) experiences with Lichtenstein experiences. METHODS Patients who underwent inguinal hernioplasty at the Gulhane Training and Research Hospital from 2013 to 2018 were included in this retrospective cohort study. The sample included 96 TEP and 90 Lichtenstein patients for a total of 186 patients. The variables assessed were hospitalization duration, postoperative early visual analog scale score, chronic pain, paresthesia, recurrence, and early postoperative complications. Data were collected from patient records and via telephone questionnaire if needed. Data analysis was done by SPSS v20, using chi-square, Fisher's exact, and Mann-Whitney U tests. RESULTS Male/female ratios were similar between the TEP and Lichtenstein groups. There was no difference in mean age between groups (p=0.1). The hospital stay was shorter (p=0.0001), and early postoperative visual analog scale score was lower in the TEP group (p=0.003). Chronic pain, paresthesia, recurrence, and early postoperative complications (hematoma, seroma, wound infection) were similar. CONCLUSIONS TEP is superior to Lichtenstein with shorter hospitalization duration and lower rates of early postoperative pain. No difference between the two techniques was found for chronic pain. We believe that laparoscopic hernioplasty approach may be the best alternative technique for inguinal hernia repair.


RESUMO OBJETIVOS As técnicas de hernioplastia inguinal foram melhoradas desde a primeira hernioplastia. Técnicas livres de tensão que aplicam materiais de malha sintética, como na abordagem de Lichtenstein, são o padrão ouro. A hernioplastia laparoscópica é a alternativa mais forte ao Lichtenstein. A superioridade da hernioplastia laparoscópica sobre o Lichtenstein é um dos principais temas debatidos. Neste estudo, procuramos encontrar uma conclusão para esse debate comparando nossas experiências totalmente extraperitoneais (TEP) com as experiências de Lichtenstein. MÉTODOS Pacientes submetidos à hernioplastia inguinal no Gulhane Training and Research Hospital de 2013 a 2018 foram incluídos neste estudo de coorte retrospectivo. A amostra incluiu 96 pacientes TEP e 90 pacientes Lichtenstein para um total de 186 pacientes. As variáveis avaliadas foram tempo de internação, escore da escala analógica visual precoce no pós-operatório, dor crônica, parestesia, recidiva e complicações pós-operatórias precoces. Os dados foram coletados dos prontuários e do questionário por telefone, se necessário. A análise dos dados foi realizada pelo SPSS v20, utilizando os testes qui-quadrado, exato de Fisher e U de Mann-Whitney. RESULTADOS As razões homem/mulher foram semelhantes entre os grupos TEP e Lichtenstein. Não houve diferença na média de idade entre os grupos (p=0,1). A permanência hospitalar foi menor (p=0,1) e a escala visual analógica precoce foi menor no grupo TEP (p=0,003). Dor crônica, parestesia, recorrência e complicações pós-operatórias imediatas (hematoma, seroma, infecção da ferida) foram semelhantes. CONCLUSÕES O TEP é superior ao Lichtenstein, com menor tempo de internação e menores taxas de dor pós-operatória precoce. Nenhuma diferença entre as duas técnicas foi encontrada para dor crônica. Acreditamos que a abordagem de hernioplastia laparoscópica pode ser a melhor técnica alternativa para correção de hérnia inguinal.

ABSTRACT

ABSTRACT This study aimed to share a single institute experience of 4,380 procedures about in-traoperative serious complications of laparoscopic urological surgeries. From January 2005 to December 2013, 4,380 cases of laparoscopic urological surgeries were recruited in our department. The distribution, incidence, and characteristics of intraoperative serious complications were retrospectively sorted out and analyzed. The surgeries were divided into three groups: very difficult (VD), difficult (D), and easy (E). The com¬plication at Satava class II was defined to be serious. One hundred thirty one cases with intraoperative serious complications were found (3.0%). The incidence of these complications was significantly increased along with the difficulty of the surgeries (P<0.05). The highest morbidity of serious complication belonged to total cystectomy with a ratio of about 17% as compared with other surgeries (P<0.05). The types of these complications included small vascular injury demanding blood transfusion (101 cases, 77.1%), large vascular (venous and artery) injury (16 cases), hypercapnia & acidosis (8 cases), and organ injury (6 cases). The cases of conversion to open surgery were 37 (≤1%). There was no significant difference in the rates of conversion to open surgery among the three groups (P>0.05). The overall tendency of the intraoperative serious complications was decreasing with the time from 2005 to 2013. In conclusion, through standardized training including improving the surgical technique, being familiar with the anatomic relationship, and constantly summarizing the experience and lessons, laparoscopic surgery could be safe and effective with not only minimal invasion but also few complications.

ABSTRACT

ABSTRACT Purpose This study aimed to compare perioperative and postoperative results of right and left laparoscopic adrenalectomy (LA), and to evaluate the impact of challenging factors on these outcomes. Materials and Methods A total of 272 patient's medical records that underwent single side LA between October 2006 and September 2017 were retrospectively reviewed. The patients were divided into 2 groups according to operation side. Moreover, pheochromocytoma, metastatic masses and adrenal lesions >5cm in size were considered to be difficult adrenalectomy cases and the outcomes of these cases were compared between two groups. Results 135 patients (49.6%) underwent right LA and 137 patients (50.4%) underwent left LA. Operation time, estimated blood loss (EBL) and hospitalization time were similar between the groups (p=0.415, p=0.242, p=0.741, respectively). Although EBL was higher on the right side than the left (p=0.038) in the first 20 cases, after this learning period has been completed, there was no significant difference between the groups. In patients with pheochromocytoma, metastatic mass and a mass >5cm in size, despite bleeding complications were clinically higher on the right side, this difference was not statistically significant. Conclusions During the learning period of LA, EBL is higher on the right side. Due to the greater risk of bleeding complications on the right side even on the hands of experienced surgeons, extra care and preoperative planning are required in patients with pheochromocytoma, metastatic masses and masses >5cm in size.

ABSTRACT

Introducción: A pesar de que la evidencia actual respalda ampliamente el abordaje laparoscópico para las resecciones de colon y recto en función de su seguridad y resultados oncológicos, el desarrollo y adopción del mismo ha sido lento y aún hoy no es de rutina en la mayoría de los centros. Se presenta la experiencia inicial en la Clínica Quirúrgica 2 del Hospital Maciel. Métodos: Estudio retrospectivo que comprende 41 resecciones laparoscópicas en el período 2016-2018. Resultados: El tiempo operatorio medio fue de 3 h para las colectomías y 4 h para las resecciones de recto. El porcentaje de conversión fue de 10%, la falla de sutura del 12% y la mortalidad a 30 días del 13%. Discusión: El abordaje laparoscópico para la colectomía y resección de recto es seguro y con aceptables resultados oncológicos de acuerdo a nuestros resultados. La curva de aprendizaje se sustenta en el volumen anual de cirugías, la realización de otros procedimientos de laparoscopía avanzada y el entrenamiento en simuladores. Conclusiones: nuestra experiencia muestra resultados inmediatos similares a los reportados en la literatura nacional, aunque el tiempo seguimiento aún es insuficiente para analizar los resultados oncológicos a largo plazo.


Introduction: Although current evidence widely supports the laparoscopic approach for resections of the colon and rectum according to their safety and oncological results, the development and adoption of the same has been slow and even today is not routine in most centers. The initial experience is presented in the Surgical Clinic 2 of the Maciel Hospital. Methods: A retrospective study comprising 41 laparoscopic resections in the period 2016-2018. Results: The mean operative time was 3 hours for colectomies and 4 hours for rectal resections. The conversion rate was 10%, the suture failure was 12% and the 30-day mortality was 13%. Discussion: The laparoscopic approach for colectomy and rectal resection is safe and with acceptable oncological results according to our results. The learning curve is based on the annual volume of surgeries, the performance of other advanced laparoscopy procedures and training in simulators. Conclusions: our experience shows immediate results similar to those reported in the national literature, although the follow-up time is still in sufficient to analyze the long-termoncological results.


Introdução: Embora as evidências atuais apóiem amplamente a abordagem laparoscópica para ressecções do cólon e do reto de acordo com sua segurança e resultados ontológicos, o desenvolvimento e a adoção dos mesmos têm sido lentos e até hoje não é rotineiro na maioria dos casos os centros. A experiência inicial é apresentada na Clínica Cirúrgica 2 do Hospital Maciel. Métodos: Estudo retrospectivo com 41 ressecções laparoscópicas no período 2016-2018. Resultados: O tempo operatório médio foi de 3 horas para colectomias e 4 horas para ressecções retais. A taxa de conversão foi de 10%, a falha na sutura foi de 12% e a mortalidade em 30 dias foi de 13%. Discussão: A abordagem laparoscópica para a colectomia e ressecção retal é segura e com resultados ontológicos aceitáveis de acordo com nossos resultados. A curva de aprendizado é baseada no volume anual de cirurgias, no desempenho de outros procedimentos avançados de laparoscopia e no treinamento em simuladores. Conclusões: nossa experiência mostra resultados imediatos semelhantes aos relatados na literatura nacional, embora o tempo de seguimento ainda seja insuficiente para analisar os resultados ontológicos em longo prazo.

ABSTRACT

La apendicitis aguda es la urgencia quirúrgica más frecuente con una incidencia de 1.17 pacientes/1,000 habitantes. Con el advenimiento de la laparoscopía, un nuevo enfoque mini invasivo surgió para el tratamiento de la apendicitis aguda. Se han demostrado algunas ventajas de este abordaje como menor dolor posoperatorio, incisiones más pequeñas, estadías hospitalarias más cortas y un rápido reintegro a las actividades diarias y laborales, con menor frecuencia de infecciones a nivel de la herida operatoria. Sin embargo, se ha asociado también con un aumento en la frecuencia de abscesos residuales intra-abdominales. En este trabajo analizamos de manera retrospectiva a todos los pacientes operados en el Hospital Maciel de Montevideo, a los que se les realizó una apendicectomía entre el 1° de Junio de 2013 y el 30 de junio de 2016, tanto por vía laparoscópica como laparotómica. Esto correspondió a un total de 426 pacientes. 235 (55%) eran hombres y 191 (45%) mujeres. La media de edad fue de 32,6 en un rango desde los 15 años hasta los 96 años de edad. 128 pacientes presentaban apendicitis edematosas (30%), 157 apendicitis flemonosa (36,9%) 76 pacientes apendicitis gangrenosas (17,8%) 37 pacientes absceso o plastrón (8,7%) y peritonitis en 28 pacientes (6,6%). Con respecto al abordaje, 287 se realizaron por vía laparoscópica (67,4%) y 139 se abordaron por vía laparotómica (32,6%). Los abscesos residuales representan el 3,28% del total, no habiendo diferencias significativas entre los diferentes abordajes. La gran mayoría de estos abscesos residuales pueden tratarse con antibioticoterapia exclusivamente. La tasa de conversión fue del 8,7%. No se observaron lesiones de víscera hueca con el abordaje laparoscópico en esta serie.


Acute appendicitis is the most frequent surgical emergency with an incidence of 17 patients/1,000 inhabitants. With the advent of laparoscopy, a new mini-invasive approach emerged for the treatment of acute appendicitis. Some advantages of this approach have been demonstrated, such as less postoperative pain, smaller incisions, shorter hospital stays and a rapid reintegration to daily and work activities, with a lower frequency of infections at the level of the operative wound. However, it has also been associated with an increase in the frequency of intra-abdominal residual abscesses. In this paper, we retrospectively analyzed all patients operated on at the Maciel Hospital in Montevideo, who underwent an appendectomy between June 1, 2013 and June 30, 2016, both laparoscopically and laparotomically. Of these 235 (55%) were men and 191 (45%) women. The average age was 32.6 in a range from 15 years to 96 years of age. 128 patients presented edematous appendicitis (30%), 157 phlegmonous appendicitis (36.9%), 76 patients gangrenous appendicitis (17.8%), 37 patients presented abscess or plastron (8.7%), and peritonitis had developed in 28 patients (6.6%). Regarding the approach, 287 were performed laparoscopically (67.4%) and 139 were approached via laparotomy (32.6%). The residual abscesses rate represents 3.28% of the series, with no significant differences in incidence between the two different approaches. The vast majority of these residual abscesses can be treated with antibiotic therapy alone. The conversion rate was 8.7%. No intestinal lesions were observed with the laparoscopic approach in this series.


A apendicite aguda é a emergência cirúrgica mais freqüente, com uma incidência de 17 pacientes/1.000 habitantes. Com o advento da laparoscopia, uma nova abordagem mini-invasiva surgiu para o tratamento da apendicite aguda. Isto têm demonstrado algumas vantagens, como menor dor pós-operatória, incisões menores, menor hospitalização e restabelecimento mais rápido as atividades diárias e ao trabalho, assim como infecções menos freqüentes ao nível da ferida cirúrgica. No entanto, também foi associado a um aumento na freqüência de abscessos residuais intra-abdominais. Foram analisados retrospectivamente todos os pacientes operados no Hospital Maciel de Montevidéu, submetidos a uma apendicectomia desde o dia 01 de Junho de 2013 a 30 de Junho de 2016, tanto por abordagem laparoscópica como laparotomica. Destes, 235 (55%) eram homens e 191 (45%) mulheres. A idade média foi de 32,6 com intervalo de 15 anos a 96 anos de idade. 128 pacientes apresentaram apendicite edematosa (30%), 157 apendicite flemonosa (36,9%) 76 pacientes apendicite gangrenosa (17,8%) 37 pacientes abscesso ou plastrão (8,7%) e peritonite em 28 pacientes (6,6% ) Quanto à abordagem, foram realizadas 287 apendicectomias por via laparoscópica (67,4%) e 139 foram abordadas por laparotomia (32,6%). Os abscessos residuais representam 3,28% do total, não havendo diferenças significativas entre as diferentes abordagens. A grande maioria desses abscessos residuais pode ser tratada apenas com antibioticoterapia. A taxa de conversão foi de 8,7% Nenhuma lesão visceral foi observada com a abordagem laparoscópica nesta série.

ABSTRACT

ABSTRACT Objective: To investigate how symptoms vary according to the appendiceal position in pediatric patients and to demonstrate that the laparoscopic approach is safe and effective in any appendiceal location by comparing each location to another. Methods: The medical records of 1,736 children aged 14 or younger who underwent laparoscopic appendectomy over a period of 14 years were analyzed retrospectively. Patients were divided according to the position of the appendiceal tip into four groups: anterior, pelvic, retrocecal and subhepatic. The Kruskal-Wallis and chi-square tests were used with the Bonferroni correction, with a significant p<0.05. Results: The appendiceal location was anterior in 1,366 cases, retrocecal in 248 cases, pelvic in 66 cases and subhepatic in 56 cases. There were no significant differences between the groups in terms of patient age and gender. Abdominal pain was the only symptom with statistically significant differences between the groups. The rate of perforated appendicitis was higher in the subhepatic and pelvic positions. Intraoperative complications and conversions were not statistically significant. Technical difficulties and operative time were higher in subhepatic position. The rate of postoperative complications was similar between the different locations, except for bowel obstruction, which was higher in pelvic appendicitis. Conclusions: The clinical symptoms of appendicitis hardly ever change with the position of the appendix. The laparoscopic approach is safe and effective, regardless the appendiceal location.


RESUMO Objetivo: Investigar como os sintomas variam de acordo com a posição do apêndice em pacientes pediátricos e demonstrar que a laparoscopia é segura e eficaz em qualquer posição do apêndice, comparando-as. Métodos: Os prontuários de 1.736 pacientes pediátricos com idade ≤14 anos submetidos à apendicectomia laparoscópica em um período de 14 anos foram analisados retrospectivamente. Os pacientes foram divididos de acordo com a posição do apêndice: anterior, pélvica, retrocecal e sub-hepático. Os testes de Kruskal-Wallis e do qui-quadrado foram usados com a correção de Bonferroni, sendo significante p<0,05. Resultados: A posição do apêndice era anterior em 1.366 casos, retrocecal em 248 casos, pélvica em 66 casos e sub-hepática em 56 casos. Não houve diferenças significativas entre os grupos quanto às variáveis idade e sexo. A dor abdominal foi a única variável com diferenças estatisticamente significantes entre os grupos. A taxa de apêndice perfurado foi superior nas posições sub-hepática e pélvica. As complicações intraoperatórias e a taxa de conversão não foram estatisticamente significativas. As dificuldades técnicas e o tempo cirúrgico foram superiores em posição sub-hepática. A taxa de complicações pós-operatórias foi semelhante entre as diferentes posições, exceto a obstrução intestinal, que foi superior em posição pélvica. Conclusões: Os sintomas da apendicite dificilmente variam com a posição do apêndice. A laparoscopia é segura e eficaz, independentemente da posição do apêndice.

ABSTRACT

ABSTRACT Introduction: Laparoscopic donor nephrectomy (LDN) has become the standard of care and popular among most of the transplant centres across the globe. Objective of this video is to report different vascular injuries, their management during LDNs and propose risk reduction strategies. Patient and methods: This was a retrospective analysis of all the LDNs performed between January 2011 and March 2016. All donor nephrectomies were performed laparoscopically by transperitoneal route, under ideal operative conditions by expert laparoscopic surgeons and by novice surgeons. Results: 858 LDNs (left, n = 797; right, n = 61) were performed during the study period with 5 cases of vascular injuries. Mean (SD) donor age was 45.5 (± 10.76) years and the operative time was 165 (± 44.4) min. Of these five cases, two had renal vein injury, while the three others had renal artery, inferior vena cava and aortic injury (one each). Four injuries occurred during left LDN and only one during a right LDN. Vascular injuries were managed using the Rescue stitch or metallic clips as indicated. Risk reduction strategy was developed to avoid vascular injuries during LDN, which include - meticulous attention to port placement, addition of fourth port, complete dissection of upper pole and pedicle before clipping, and judicious use of ultrasonic diathermy. Conclusions: Careful evaluation of computed tomography angiography just before surgery will act like a global positioning system (GPS) for the operating surgeon. Rescue stitch is a saviour. Not to panic and being well versed with the risk reduction strategies of laparoscopy and rescue measures is of paramount importance.

ABSTRACT

ABSTRACT Objectives: Nephrectomy due to stone disease may be a challenging procedure owing to the presence of significant inflammation and infection, involving high complication rate. The objective of our study was to identify predictors for complications of nephrectomy for urolithiasis. Patients and Methods: A retrospective review of 149 consecutive patients > 18y submitted to simple nephrectomy for urolithiasis from January 2006 to July 2012 was performed. Clinical data, computed tomography findings and pathology report were analyzed. Postoperative complications were categorized based on Clavien - Dindo classification. Logistic multivariate regression models assessed the predictors for surgical complications of nephrectomy for urolithiasis. Results: Eighty-three (55.7%) patients were submitted to laparoscopic nephrectomy and 66 (44.2%) to open procedure. Conversion to open surgery was necessary in 19.2% (16 / 83). On univariable analysis, higher preoperative chronic kidney stage (p = 0.02), Charlson comorbidity index ≥ 2 (p = 0.04), higher ASA score (p = 0.001), urgency due to sepsis (p = 0.01), kidney size ≥ 12 cm (p = 0.006), renal and perirenal abscess (p = 0.004 and 0.002 respectively) and visceral adhesion (p = 0.04) were associated with Clavien - Dindo score > 1. On multivariate analysis, higher ASA score (p = 0.01), urgency due to sepsis (p = 0.03), kidney size ≥ 12 cm (p = 0.04) and preoperative abscess (p = 0.04) remained significantly associated with complications. End - stage renal disease with dialysis was needed post - operatively in 3.4% (5 / 144) of patients. Conclusions: We identified that higher ASA score, urgency due to sepsis, kidney size ≥ 12 cm and preoperative abscess were associated with Clavien - Dindo score > 1.

ABSTRACT

This study aimed to observe the effects of lung-protective ventilation (LPV) on oxygenation index (OI) and postoperative pulmonary complications (PPCs) after laparoscopic radical gastrectomy in middle-aged and elderly patients. A total of 120 patients who were scheduled to undergo laparoscopic radical gastrectomy with an expected time of >3 h were randomly divided into conventional ventilation (CV group) with tidal volume (TV) of 10 mL/kg without positive end-expiratory pressure (PEEP), and lung-protective ventilation (PV group) with 7 mL/kg TV and personal level of PEEP with regular recruitment maneuver every 30 min. Measurements of OI, modified clinical pulmonary infection score (mCPIS), and PPCs were assessed during the perioperative period. Fifty-seven patients in the CV group and 58 in the PV group participated in the data analysis. Patients in the PV group showed better pulmonary dynamic compliance, OI, and peripheral capillary oxygen saturation during and after surgery. The mCPIS was significantly lower in the PV group than in the CV group after surgery. The incidence rate of PPCs was lower in the PV group than in the CV group and the difference was significant in patients whose ventilation time was longer than 6 h in both groups. LPV during laparoscopic radical gastrectomy significantly improved pulmonary oxygenation function and reduced postoperative mCPIS and the incidence of PPCs during the early period after surgery of middle-aged and elderly patients, especially patients whose mechanical ventilation time was longer than 6 h.
