Dexmedetomidine can not reduce the incidence of acute and chronic kidney disease after laparoscopic radical nephrectomy: a propensity score matching-based analysis / 南方医科大学学报

OBJECTIVE@#To investigate the effect of dexmedetomidine (DEX) on renal function after laparoscopic radical nephrectomy.@*METHODS@#We reviewed the clinical data of 282 patients with renal cell carcinoma (RCC), who underwent laparoscopic radical nephrectomy (LRN) in the Department of Urology, Third Medical Center of PLA General Hospital from November, 2020 and June, 2022.According to whether DEX was used during the operation, the patients were divided into DEX group and control group, and after propensity score matching, 99 patients were finally enrolled in each group.The incidence of acute kidney injuries were compared between the two groups.Serum creatinine (sCr) data within 3 months to 1 year after the operation were available in 51 patients, including 26 in DEX group and 25 in the control group, and the incidence of chronic kidney disease (CKD) was compared between the two groups.@*RESULTS@#After propensity score matching and adjustment for significant covariates, there were no significant differences in postoperative levels of sCr, cystatin C (CysC), β2-microglobulin (β2-MG), hemoglobin (Hb), or C-reactive protein (CRP), extubation time, incidence of AKI, or length of hospital stay between the two groups (P>0.05).The intraoperative urine volume was significantly higher in DEX group than in the control group (P < 0.05).A significant correlation between AKI and CKD was noted in the patients (P < 0.05).The incidence of CKD did not differ significantly between the two groups (P>0.05).@*CONCLUSION@#DEX can not reduce the incidence of AKI or CKD after LRN.

Diagnosis, prevention and treatment of post-operative rare complications after radical gastrectomy for gastric cancer / 中华胃肠外科杂志

Radical gastrectomy for gastric cancer results in various post-operative complications, and the influencing factors are complicated. The diagnosis, treatment and prevention of common complications have been reported in many literatures. However, there are few reports on the prevention and treatment of rare complications. Rare complications after radical gastrectomy are often overlooked due to their low incidence. In addition, there are few guidelines and expert consensus regarding to the rare complications. Therefore, clinicians may lack experience in the diagnosis, treatment and prevention of rare complications after radical gastrectomy. Based on the literature review and the author's experience, this article systematically reviews seven rare complications after radical gastrectomy (duodenal stump fistula, pancreatic fistula, chyle leakage, esophagomediastinal fistula, internal hernia, gastroparesis, and intussusception). This article aims to provide a comprehensive reference for the diagnosis, treatment and prevention of rare complications after radical gastrectomy for gastric cancer patients.

Prevention and management of complications related to laparoscopic spleen-preserving hilar lymph node dissection for gastric cancer / 中华胃肠外科杂志

Hilar splenic lymph node metastasis is one of the risk factors for poor prognosis in patients with proximal gastric cancer. Laparoscopic spleen-preserving splenic hilar lymph node dissection (LSPSHLD) can effectively improve the survival benefits of patients at high risk of splenic hilar lymph node metastasis. However, LSPSHLD is still a challenging surgical difficulty in radical resection of proximal gastric cancer. Moreover, improper operation can easily lead to splenic vascular injury, spleen injury and pancreatic injury and other related complications, due to the deep anatomical location of the splenic hilar region and the intricate blood vessels.Therefore, in the prevention and treatment of LSPSHLD-related complications, we should first focus on prevention, clarify the indication of surgery, and select the benefit group of LSPSHLD individually, so as to avoid the risk caused by over-dissection. Meanwhile, during the perioperative period of LSPSHLD, it is necessary to improve the cognition of related risk factors, conduct standardized and accurate operations in good surgical field exposure and correct anatomical level to avoid surrounding tissues and organs injury, and master the surgical skills and effective measures to deal with related complications, so as to improve the surgical safety of LSPSHLD.

Interpretation of Chinese expert consensus on prevention and treatment of complications related to digestive tract reconstruction after laparoscopic radical gastrectomy for gastric cancer (2022 edition) / 中华胃肠外科杂志

Gastric cancer is one of the most common gastrointestinal malignancies in China. D2 radical gastrectomy is the main treatment for advanced gastric cancer patients. With the advancement of laparoscopic technology, laparoscopic radical gastrectomy has been gradually developed in the world, and even popularized in China. There have been a lot of literature reports on the indications, the scope of lymph node dissection and the improvement of techniques of laparoscopic radical gastrectomy for gastric cancer. Relevant guidelines or consensus for radical gastrectomy. The prevention and treatment of complications of gastrointestinal reconstruction for laparoscopic radical gastric cancer surgery is a major concern for gastrointestinal surgeons. Once complications occur in digestive tract reconstruction, it would increase the hospitalization cost, prolong the hospitalization stay of patients, delay follow-up chemotherapy, and even lead to postoperative death or other serious consequences. Therefore, it is of positive and far-reaching clinical significance to pay attention to the techniques of gastrointestinal reconstruction after laparoscopic radical gastric cancer surgery, to reduce the occurrence of gastrointestinal reconstruction complications, and to detect and reasonably manage related complications in a timely manner. The Chinese expert consensus on prevention and treatment of complications related to digestive tract reconstruction after laparoscopic radical gastrectomy for gastric cancer (2022 edition) has significance value for reducing the occurrence of gastrointestinal reconstruction complications. This manuscript mainly serves as the interpretation and supplement of this Consensus.

Current status and future prospects of robotic surgical system in radical gastrectomy for gastric cancer / 中华胃肠外科杂志

Robotic gastrectomy (RG) has always been a hot topic in the field of minimally invasive surgery for gastric cancer. More and more studies have confirmed that short- and long-term outcomes of RG are similar to those of laparoscopic gastrectomy. Robotic surgical systems have more advantages in specific regional lymph node dissection. More delicate operation can reduce intraoperative blood loss and the incidence of postoperative complications. Robotic surgical systems are also more ergonomically designed. However, there are also some problems such as high surgical cost, lack of tactile feedback and prolonged total operation time. In the future, robotic surgical system may be further developed in the direction of miniaturization, intelligence and modularity. At the same time, the robotic surgical system deeply integrated with artificial intelligence technology may realize the automation of some operation steps to some extent.

Elective incisional hernia repair: lower risk of postoperative wound infection with laparoscopic versus open repair

INTRODUCTION@#The superiority of laparoscopic repair over open repair of incisional hernias (IHs) in the elective setting is still controversial. Our study aimed to compare the postoperative outcomes of laparoscopic and open elective IH repair in an Asian population.@*METHODS@#This retrospective study was conducted in an acute general hospital in Singapore between 2010 and 2015. Inclusion criteria were IH repair in an elective setting, IHs with diameter of 3-15 cm, and location at the ventral abdominal wall. We excluded patients who underwent emergency repair, had recurrent hernias or had loss of abdominal wall domain (i.e. hernia sac containing more than 30% of abdominal contents or any solid organs). Postoperative outcomes within a year such as recurrence, pain, infection, haematoma and seroma formation were compared between the two groups.@*RESULTS@#There were 174 eligible patients. The majority were elderly Chinese women who were overweight. Open repair was performed in 49.4% of patients, while 50.6% underwent laparoscopic repair. The mean operation time for open repair was 116 minutes (116 ± 60.6 minutes) and 139 minutes (136 ± 64.1 minutes) for laparoscopic repair (P = 0.079). Within a year after open repair, postoperative wound infection occurred in 15.1% of the patients in the open repair group compared to 1.1% in the laparoscopic group (P = 0.0007). Postoperative pain, recurrence and haematoma/seroma formation were comparable.@*CONCLUSION@#Elective laparoscopic IH repair has comparable outcomes with open repair and may offer the advantage of reduced postoperative wound infection rates.

Internal hernia after laparoscopic left colectomy: case series and review of the literature

Objective: Laparoscopic colectomy has gained acceptance as a standard treatment for benign and malignant colorectal disease, such as diverticular disease and cancer, among others. Same as in open surgery, the laparoscopic approach carries a low risk of small bowel obstruction in the postoperative period, but in laparoscopic surgery, internal hernia after laparoscopic left colectomy may be a cause of small bowel obstruction with a significant risk of morbidity and mortality. This rare complication may be prevented with routine closure of the mesenteric defects created during the colectomy. Methods: We present four cases of internal herniation after laparoscopic colectomy. Two cases were after laparoscopic left colectomy and two after laparoscopic low anterior resection. All four cases had full splenic flexure mobilization. Routine closure of the mesenteric defect was not performed in the initial surgery. Results: The four patients were treated by laparoscopic reintervention with closure of the mesenteric defect. In two of them, conversion to open surgery was necessary. One of the patients developed recurrent internal herniation after surgical reintervention with mesenteric closure of the defect. All patients were managed without need for bowel resection, and mortality rate was 0%. Conclusion Internal herniation after laparoscopic colorectal surgery is a highly morbid complication that requires prompt diagnosis and management and should be suspected in the early postoperative period. Additional studies with extended follow-up are required to establish recommendations regarding its prevention and management. (AU)

Abordaje abierto versus laparoscópico para la reconstitución del tránsito luego de la cirugía de Hartmann: resultados de una experiencia de 10 años / Open versus laparoscopic approach for Hartmann's reversal: results of a 10-year retrospective cohort study

Resumen Objetivo: El objetivo de este estudio es comparar los resultados perioperatorios del abordaje abierto (AA) con el abordaje laparoscópico (AL) para la reconstitución de tránsito (RT), y determinar factores de riesgo asociados a morbilidad posoperatoria. Material y Métodos: Se estudiaron pacientes consecutivos sometidos a RT entre enero de 2007 y diciembre de 2016 en nuestro centro. Se excluyeron aquellos con grandes hernias incisionales que requirieran reparación abierta simultánea. Se consignaron variables demográficas y perioperatorias, y se compararon ambos grupos. Además, se realizó una regresión logística para la identificación de factores de riesgo asociados a morbilidad posoperatoria en la serie. Resultados: Se realizaron 101 RT en el período. Se excluyeron 14 casos por hernia incisional, por lo que se analizaron 87 casos (46 AA y 41 AL). Diez pacientes en el grupo AL (24,4%) requirieron conversión, principalmente por adherencias. La morbilidad total de la serie fue de 36,8%, siendo mayor en el AA (50% vs 21,9%, p = 0,007). Hubo una filtración anastomótica en cada grupo. La estadía posoperatoria fue de 5 (3-52) días para el AL y 7 (4-36) días para el AA (p < 0,001). En la regresión logística, sólo el AA fue un factor de riesgo independientemente asociado a morbilidad posoperatoria (OR 2,89, IC 95% 1,11-7,49; p = 0,029). Conclusión: El abordaje laparoscópico se asocia a menor morbilidad y estadía posoperatoria que el abordaje abierto para la reconstitución del tránsito pos-Hartmann. En nuestra serie, el abordaje abierto fue el único factor independientemente asociado a morbilidad posoperatoria.

Introduction: Hartmann's reversal (HR) is considered a technically demanding procedure and is associated with high morbidity rates. Aim: The aim of this study is to compare the perioperative results of the open approach (OA) with the laparoscopic approach (LA) for HR, and to determine the risk factors associated with postoperative morbidity. Material and Methods: Consecutive patients undergoing HR between January 2007 and December 2016 at a university hospital were included. Patients with large incisional hernias that required an open approach a priori were excluded from the analysis. Demographic and perioperative variables were recorded. Analytical statistics were carried out to compare both groups, and a logistic regression was performed to identify risk factors associated with postoperative morbidity in the series. Results: A hundred and one HR were performed during the study period. Fourteen cases were excluded due to large incisional hernias, so 87 cases (46 OA and 41 LA) were analyzed. Ten patients in the LA group (24.4%) required conversion, mainly due to adhesions. The total morbidity of the series was 36.8%, being higher in the OA group (50% vs. 21.9%, p = 0.007). There was one case of anastomotic leakage in each group. The length of stay was 5 (3-52) days for LA and 7 (4-36) days for OA (p < 0.001). In the logistic regression, the OA was the only independent risk factor associated with postoperative morbidity in HR (OR 2.89, IC 95% 1.11-7.49; p = 0.029). Conclusion: A laparoscopic approach is associated with less morbidity and a shorter length of stay compared to the open approach for Hartmann's reversal. An open approach was the only factor independently associated with postoperative morbidity in our series.

Proteína C reactiva y su relación con las complicaciones posoperatorias en cirugía colorrectal electiva / Association between C-reactive protein and postoperative complications in elective colorectal surgery

RESUMEN Antecedentes: el uso de la proteína C reactiva (PCR) ha adquirido relevancia como identificador de complicaciones posoperatorias La morbilidad en cirugía colorrectal se estima en un 30% de los pacientes operados, lo que demanda medidas para su temprana identificación y terapéutica. Objetivo: describir las curvas de mediciones sucesivas de PCR y su relación con el desarrollo de complicaciones posoperatorias y niveles de glóbulos blancos en una serie de pacientes operados de cirugía colorrectal. Materiales y métodos: se realizó una revisión retrospectiva sobre un registro prospectivo de 2205 pacientes operados por la División de Cirugía Gastroenterológica del Hospital de Clínicas, entre enero de 2019 y julio de 2020. Se incluyeron 69 pacientes que cumplieron con los criterios de selección. Se consignaron datos del seguimiento clínico y dosaje de PCR, recuento de glóbulos blancos, vía de abordaje y desarrollo de complicaciones. Resultados: el promedio de edad fue de 59 años (DS 13,6; rango 33-85), 31 fueron hombres (43%). La tasa de complicaciones fue del 13,04%; más frecuente fue la fístula anastomótica (fístula, colección), seguida por complicaciones de la herida (hematoma, evisceración). Todos los pacientes mostraron un ascenso inicial del valor de PCR entre el 2° y 3er día, en relación con la lesión quirúrgica, los no complicados presentaron una cinética de descenso y los complicados. curvas de segundo ascenso o no descenso en las mediciones seriadas de PCR, y exhibían valores superiores de PCR cada día Se advirtieron diferencias estadísticamente significativas entre los valores de proteína C reactiva al 5° día posoperatorio en el subgrupo de pacientes complicados con respecto a aquellos con un curso indolente (28 mg/dL vs. 6,1 mg/dL, p < 0,001; IC: 11,24-39,61). hubo diferencia significativa al 5o día entre complicados y no complicados, independientemente de la vía de abordaje. con un valor de corte de PCR de 10,92 mg/dL obtuvimos una sensibilidad del 87,50% y una especificidad del 100% para excluir complicaciones. Conclusiones: la medición de la proteína C reactiva de forma seriada en los posoperatorios de cirugía colorrectal mostró un correlato con la identificación temprana de las complicaciones en nuestra serie, tanto en sus valores absolutos diarios como en la cinética de su comportamiento. se formula el uso de valores de corte para el alta segura.

ABSTRACT Background: The use of C-reactive protein (CRP) has gained relevance as a marker of marker of postoperative complications. As the incidence of complications of colorectal surgery is estimated to be of 30%, measures should for their early identification and treatment. Objective: To describe the performance of consecutive CRP determinations and their relationship with the development of postoperative complications and with white blood cell count in a series of patients undergoing colorectal surgery. Materials and methods: A retrospective review was performed using a prospective registry of 2205 patients operated on at the Department of Digestive Surgery of Hospital de Clínicas, between January 2019 and July 2020. A total of 69 patients fulfilling the selection criteria were included. Clinical follow-up data, CRP levels, white blood cell count, type of approach and development of complications were recorded. Results: Mean age was 59 years (SD 13.6; range 33-85) and 31 were men (43%). The complication rate was 13.04%. Anastomotic leak (fistula, fluid collection) was the most common complication, followed by surgical site complications (hematoma, evisceration). All patients showed an initial increase in CRP values between days 2 and 3, in relation with the surgical lesion, and then decreased in those without complications. Patients with complications had second rise or lack of decrease in serial CRP measurements, and higher CRP values each day. There were statistically significant differences between the CRP levels on postoperative day 5 in the subgroup of patients with complications compared with those with an indolent course (28 mg/dL vs. 6.1 mg/dL, p < 0.001; CI: 11.24-39.61). There was a significant difference on day 5 between patients with and without complications, irrespective of the approach. With a cut-off value of CRP of 10.92 mg/dL on postoperative day 5 we obtained a sensitivity of 87.50% and specificity of 100% to rule out complications. Conclusions: Serial determination of CRP in the postoperative period after colorectal surgery was associated with early identification of complications in our series, both in daily absolute values and in the kinetics of its performance. The use of cut-off values for safe discharge is proposed.

Abordaje quirúrgico y evolución posoperatoria en reintervenciones de complicaciones en cirugía colorrectal laparoscópica, 15 años de experiencia / Surgical approach and postoperative clinical course in reinterventions for complications following laparoscopic colorectal surgery: 15 years of experience

Resumen Objetivo: Comparar tres abordajes quirúrgicos (abierto, laparoscópico y laparoscópico convertido) para el manejo de complicaciones posoperatorias en cirugía colorrectal electiva realizadas primariamente por vía laparoscópica. Materiales y Método: Este estudio de cohorte retrospectivo incluyó pacientes reoperados después de una cirugía colorrectal laparoscópica electiva, agrupándose según la vía de abordaje de reoperación: abierta (RVA), laparoscópica (RVL) y laparoscópica convertida (RVLC). Las variables estudiadas fueron: preoperatorias (edad, sexo, puntuación ASA, IMC, comorbilidades e historia quirúrgica); operatorias (causa de reoperación, latencia para reoperación, tiempo operatorio, cirugía realizada y causa de conversión); y posoperatorias (tránsito intestinal, días de hospitalización, días de UCI, complicaciones médicas, infección del sitio quirúrgico, evisceración, transfusión y mortalidad a los 30 días). Resultados: Sin diferencias significativas para las variables preoperatorias y operatorias. En cuanto a las variables posoperatorias, el grupo de reoperaciones por vía laparoscópica, tuvo menos días de hospitalización (p = 0,012), menos días de UCI (p = 0,001) y un tránsito intestinal más rápido para reaparición de gases, heces y retorno a dieta sólida (p = 0,008, p = 0,029, p = 0,030, respectivamente). No hubo diferencias significativas en la infección del sitio quirúrgico, la evisceración, las complicaciones médicas, la transfusión y la mortalidad. Discusión y Conclusión: Este estudio reveló una mejor evolución clínica posoperatoria en el grupo de reoperación laparoscópica, con menor estancia hospitalaria y en UCI, y reducción del íleo posoperatorio, sin aumento de la morbimortalidad. Por lo tanto, la reoperación laparoscópica en cirugía colorrectal podría ser el abordaje más adecuado en pacientes debidamente seleccionados.

Aim: To compare three approaches (laparoscopic, open, and conversion of laparoscopic approach) for the management of intra-abdominal surgical complications after elective laparoscopic colorectal surgery. Materials and Method: This was a retrospective cohort study including patients who required reoperation due to an intra-abdominal surgical complication after initial elective laparoscopic colorectal surgery. Patients were grouped according to the reoperation approach-laparoscopic reoperation, laparoscopic reoperation that required conversion to open surgery, and open reoperation. Pre-operative variables (age, gender, ASA score, BMI, comorbidities, and surgical history), operative variables (cause of reoperation, latency for reoperation, operative time, surgery performed, and cause of conversion), and post-operative variables (intestinal transit, hospital days, ICU days, medical complications, surgical site infection, evisceration, transfusion and 30-day mortality), were compared between groups. Results: There were no significant differences between groups among the pre-operative and operative variables. In terms of post-operative variables, the laparoscopic reoperation group, had fewer hospital days (p = 0.012), fewer ICU days (p = 0.001), and faster intestinal transit regarding gas, stool and return to solid diet (p = 0.008, p = 0.029 and p = 0.030, respectively). However, there were no significant differences in surgical site infection, evisceration, medical complications, transfusion, and mortality. Discussion and Conclusión: This study revealed better post-operative clinical course in the laparoscopic reoperation group, with shorter hospital and ICU stay, and reduced postoperative ileus, without increased morbidity or mortality. Laparoscopic reoperation for complications after elective laparoscopic colorectal surgery may therefore be the preferred approach.

Effect of duodenal stump reinforcement on postoperative complications in patients undergoing laparoscopic radical gastrectomy / 中华胃肠外科杂志

Objective: To evaluate the influence of duodenal stump reinforcing on the short-term complications after laparoscopic radical gastrectomy. Methods: A retrospective cohort study with propensity score matching (PSM) was conducted. Clinical data of 1204 patients with gastric cancer who underwent laparoscopic radical gastrectomy at the First Affiliated Hospital of Army Medical University from April 2009 to December 2018 were collected. The digestive tract reconstruction methods included Billroth II anastomosis, Roux-en-Y anastomosis and un-cut-Roux- en-Y anastomosis. A linear stapler was used to transected the stomach and the duodenum. Among 1204 patients, 838 were males and 366 were females with mean age of (57.0±16.0) years. Duodenal stump was reinforced in 792 cases (reinforcement group) and unreinforced in 412 cases (non-reinforcement group). There were significant differences in resection range and anastomotic methods between the two groups (both P<0.001). The two groups were matched by propensity score according to the ratio of 1∶1, and the reinforcement group was further divided into purse string group and non-purse string group. The primary outcome was short-term postoperative complications (within one month after operation). Complications with Clavien-Dindo grade ≥ III a were defined as severe complications, and the morbidity of complication between the reinforcement group and the non-reinforcement group, as well as between the purse string group and the non-purse string group was compared. Results: After PSM, 411 pairs were included in the reinforcement group and the non-reinforcement group, and there were no significant differences in baseline data between the two groups (all P>0.05). No perioperative death occurred in any patient.The short-term morbidity of postoperative complication was 7.4% (61/822), including 14 cases of anastomotic leakage (23.0%), 11 cases of abdominal hemorrhage (18.0%), 8 cases of duodenal stump leakage (13.1%), 2 cases of incision dehiscence (3.3%), 6 cases of incision infection (9.8%) and 20 cases of abdominal infection (32.8%). Short-term postoperative complications were found in 25 patients (6.1%) and 36 patients (8.8%) in the reinforcement group and the non-reinforcement group, respectively, without significant difference (χ2=2.142, P=0.143). Nineteen patients (2.3%) developed short-term severe complications (Clavien-Dindo grade ≥IIIa), while no significant difference in severe complications was found between the two groups (1.7% vs. 2.9%, χ2=1.347, P=0.246). Sub-group analysis showed that the morbidity of short-term postoperative complication of the purse string group was 2.6% (9/345), which was lower than 24.2% (16/66) of the non-purse string group (χ2=45.388, P<0.001). Conclusion: Conventional reinforcement of duodenal stump does not significantly reduce the incidence of duodenal stump leakage, so it is necessary to choose whether to reinforce the duodenal stump individually, and purse string suture should be the first choice when decided to reinforce.

Principais implicações terapêuticas à qualidade de vida de pacientes com câncer de colo uterino: uma revisão narrativa / Therapeutic implications to the quality of life of cervical cancer's patients: a narrative review

O câncer de colo uterino é o quarto tipo mais incidente e fatal entre as mulheres no Brasil e no mundo, o que representa mundialmente em torno de 600 mil novos casos e mais de 300 mil mortes a cada ano. Assim como o diagnóstico, o tratamento da doença pode impactar de forma significativa a qualidade de vida dessas pacientes. A aplicação de questionários que avaliem os diferentes aspectos da qualidade de vida das mulheres afetadas por esse câncer é uma ferramenta relevante, pois auxilia na compreensão e identificação dos principais danos relacionados ao tratamento. Este trabalho visa analisar a literatura atual que investiga e relata os principais efeitos à qualidade de vida de mulheres com câncer de colo uterino associados a diferentes modalidades terapêuticas e, desse modo, contribuir nas escolhas de tratamento e manejo clínico que resultem em menores impactos à qualidade de vida dessas mulheres.(AU)

Cervical cancer is the fourth most incident and fatal cancer type among women in Brazil and worldwide. This data represents around 600 thousand new cases worldwide each year and more than 300 thousand lives lost. Both diagnosis and treatment can significantly impact the quality of life of cervical cancer patients. The application of questionnaires that assess the different aspects of the quality of life of women affected by this cancer is a relevant tool, as it helps to understand and identify the main damages related to the treatment. This article aims to analyze the current literature that reports the main effects on the quality of life of women with cervical cancer associated with different therapeutic modalities. In this way, the review could assist in the treatment choices that imply less impact on the quality of life of these women.(AU)

Objetivo: Analizar los resultados a largo plazo de pacientes sometidos a PGL. Materiales y Método: Estudio prospectivo y descriptivo, se incluyeron pacientes obesos adultos que cumplieron criterios universales para cirugía bariátrica. Se registraron datos epidemiológicos, comorbilidades, tiempo operatorio, estadía hospitalaria, porcentaje de pérdida de exceso de IMC (% PEIMC), complicaciones posoperatorias y resolución de comorbilidades. El seguimiento se efectuó con controles periódicos anuales hasta el año 2020. Resultados: Se inició la selección de pacientes durante el año 2010. Se realizaron 26 intervenciones desde enero de 2011 hasta mayo de 2012. Todas las pacientes fueron de género femenino. El IMC preoperatorio promedio fue 38,8 kg/m2 (DS 3,8). El % PEIMC promedio al año, 3 años y 9 años de posoperado, fue 62,2% (DS 27,1), 40,2% (DS 24,5) y 28% (DS 31,9), respectivamente. Las complicaciones, basadas en la clasificación de Clavien-Dindo (CD), durante los primeros 30 días de posoperatorio fueron 21 pacientes con tipo I, 1 con tipo II, y 2 pacientes con complicaciones tipo IVa. A los 9 años de posoperado, 9 pacientes presentaban efectos adversos tipo I. No hubo mortalidad. Hasta los 3 años hubo corrección de comorbilidades. Se objetivaron 3 pacientes diabéticas al final del estudio, 2 de ellas previamente sanas. Conclusiones: El % PEIMC a largo plazo fue insuficiente. El porcentaje de complicaciones es mayor que en otras técnicas. No recomendamos la realización de la PGL.

Background: The international experience has failed to reproduce the first studies of laparoscopic gastric plication (LGP). Aim: The objective is to analyze the outcomes after 10 years of follow-up of patients subjected to LGP. Materials and Method: Prospective and descriptive study, in which obese adult patients who met universal criteria for bariatric surgery were included. Epidemiological data, comorbidities, operating time, hospital stay, percentage of excess BMI loss (% EBMIL) and resolution of comorbidities were collected. The follow-up was realized by annual periodic controls until 2020. Results: Patient selection began in 2010. A total of 26 interventions were performed from January 2011 to May 2012. All patients were female. The average preoperative Body Mass Index (BMI) was 38.8 kg/m2 (SD 3.8). The average % EBMIL at 1st, 3rd and 9 th postoperative years was 62.2% (SD 27.1), 40.2% (SD 24.5) and 28% (SD 31.9), respectively.Complications, based in Clavien Dindo classification, during the first 30 postoperative days was: 21 patients with type I, 1 type II, and 2 patients with complications type IVa. At 9 th postoperative year, 9 patients presented adverse effect type I. There was no mortality. Until the 3rd year there was correction of comorbidities. Three diabetic patients were observed at the end of the study, 2 previously healthy. Conclusions: The long term % EBMIL was insufficient. The percentage of complications is higher than in other techniques. We do not recommend the LGP.

Comparación de los desenlaces clínicos con cuatro técnicas de apendicetomía laparoscópica tras la implementación de políticas de reúso de dispositivos médicos / Comparison of clinical outcomes with four laparoscopic appendectomy techniques after implementation of medical devices reuse policy

Resumen Objetivo: En este estudio se comparan los desenlaces clínicos de cuatro técnicas de apendicectomía laparoscópica utilizadas en una institución colombiana para el manejo de la apendicitis aguda tras la adopción de políticas de reúso y reprocesamiento de dispositivos médicos para la Región de las Américas (2014). Materiales y Método: Mediante el análisis de varianza de una vía (ANOVA) y la prueba de Kruskal Wallis, se compararon las tasas de infección de sitio operatorio (ISO), reoperación no planeada, readmisión y mortalidad (en los primeros 30 días del postoperatorio) de las siguientes técnicas: Técnica 1: Ligadura del muñón apendicular con endonudo y disección del mesenterio apendicular con electrocoagulación bipolar convencional; Técnica 2: Clipaje del muñón con endoclip de polímero y disección del mesenterio con electrocoagulación bipolar convencional; Técnica 3: Clipaje del muñón con endoclip de polímero y disección del mesenterio con electrocoagulación monopolar; Técnica 4: Clipaje del muñón y disección roma y ligadura del mesenterio con endoclip de polímero. Resultados: Se incluyeron 551 pacientes. No se encontraron diferencias en los ANOVAs en cuanto a las características demográficas de los pacientes por cada técnica. Los desenlaces globales fueron: ISO (5,44%), reoperación no planeada (3,08%), readmisión (15,97%) y mortalidad (0,18%). Se encontraron diferencias significativas (p < 0,05) en estos desenlaces explicados por mayores tasas de ISO y reoperación con la Técnica-1. Conclusiones: Los desenlaces globales de la apendicectomía laparoscópica tras la adopción de políticas de reúso de dispositivos médicos se encuentran dentro de los aceptados globalmente cuando se utilizan las Técnicas 2-3-4 en poblaciones equivalentes de pacientes con apendicitis aguda. En este contexto, nuestros resultados invitan a utilizar con precaución la Técnica-1.

Aim: The present study sought to compare the clinical outcomes between four operative techniques for laparoscopic appendectomy in a Colombian institution, following the adoption of reuse and reprocessing policies for medical devices in the Region of Americas (2014). Materials and Methods: One-way analysis of variance (ANOVA) and Kruskal Wallis tests were used to compare the rates of Surgical Site Infection (SSI), unplanned reoperation, readmission and mortality (confined to 30 days after surgery) of these operative techniques: Technique 1: Ligature of appendiceal stump with endo stitch plus mesenteric dissection with conventional bipolar electrocoagulation; Technique 2: Clipping of stump with polymer endoclip plus mesenteric dissection with conventional bipolar electrocoagulation; Technique 3: Clipping of stump with polymer endoclip plus mesenteric dissection with monopolar electrocoagulation; Technique 4: Clipping of stump plus mesenteric dissection with polymer endoclip. Results: A total of 551 patients were included. No differences were found in the demographic characteristics of the patients between techniques during ANOVAs. The global outcomes were SSI (5.44%), unplanned reoperation (3.08%), readmission (15.97%) and mortality (0.18%). Significant differences were found (p < 0.05) in these outcomes explained by higher rates of SSI and unplanned reoperation with Technique 1. Conclusions: The overall outcomes of laparoscopic appendectomy, after the adoption of policies for the reuse and reprocessing of medical devices, are similar to those accepted globally when using operative techniques 2-3-4 in equivalent populations of patients with acute appendicitis. In this context, our results invite to use with caution technique-1.

Quistectomía laparoscópica en quiste hidatídico hepático / Laparoscopic cystectomy in hidatidid cyst

Resumen Objetivo: Describir resultados en términos de morbilidad y mortalidad del tratamiento de quistes hidatídicos hepáticos (QHH) por vía laparoscópica en una serie de pacientes consecutivos. Comparar calidad de vida (CV) de pacientes sometidos a quistectomía laparoscópica (QL) con pacientes llevados a colecistectomía laparoscópica. Materiales y Método: Serie de casos con seguimiento de pacientes con QHH, sometidos a QL. Analizamos datos con Stata® 10.0, mediante medidas de tendencia central y dispersión. Describimos 4 variables, realizando seguimiento con tomografía computada (TC) abdominal. Aplicamos encuesta de calidad de vida SF-36. Resultados: Incluimos 12 pacientes, 58,3% de género femenino. Número de quistes 2,02 ± 1,56, volumen quístico mayor 809,16 ± 766,05 ml, diámetro de quiste mayor 11,77 ± 4,33 cm, predominando en lóbulo hepático derecho (58%). Tiempo operatorio promedio 234,1 ± 52,9 minutos. Estadía hospitalaria promedio 11,5 ± 14,5 días. Morbilidad en 16,6%, sin mortalidad posoperatoria. Seguimiento con imágenes promedio fue 7,9 ± 4,3 meses, encontrando cavidades residuales pequeñas y asintomáticas en 50% de pacientes. No reportamos recidivas. Al comparar CV con grupo de colecistectomía sólo encontramos diferencia respecto a vitalidad (p = 0,04). Discusión: Aunque nuestra serie es pequeña y presenta mayor tiempo quirúrgico (por selección de pacientes) y mayor estancia hospitalaria que en otras series de QL, presenta menor porcentaje de recidivas, de fístulas biliares y no presenta mortalidad, concordando con otras series de QL que la recomiendan como opción terapéutica. Conclusiones: La QL para el tratamiento de los QHH resulta una cirugía aceptable, con morbilidad y mortalidad comparable con reportes de cirugía abierta.

Aim: To describe results in morbidity and mortality terms of the hepatic hydatidosis (HHC) treatment by laparoscopic route in selected patients. In addition, compare the quality of life (QL) of cystomectized vs cholecystectomized patients, both laparoscopically. Materials and Method: Case series with follow-up of patients with HHC, undergoing laparoscopic cystectomy (LC). Data analysis, through measures of central tendency and dispersion, performed with Stata® 10.0. Analyzing 4 variables followed-up with abdominal computed tomography. A quality of life survey SF-36" was applied. Results: 12 patients were included, 58.3% female gender. Cysts number 2.02 ± 1.56, largest cystic volume 809.16 ± 766.05 ml, larger cyst diameter 11,77 ± 4,33 cm. Right hepatic lobe is predominantly 58%. Surgical time, 234.16 ± 52.95 minutes. Hospital stay, 11.58 ± 14.55 days. Morbidity 16.6%, with no postoperative mortality. Follow-up, performed at 7.9 ± 4.3 months, finding residual cavity in 50%, no recurrences were reported. At comparing QL with cholecystectomy group, we only found differences at the vitality item (p = 0,04). Discussion: Although our series is small and has a longer surgical time (by patient selection) and a longer hospital stay than in other LC series, it has a lower recurrences percentage, biliary fistulas, and no mortality, agreeing with other LC series that recommend it as a therapeutic option. Conclusions: The laparoscopic approach for the HHC treatment, is an acceptable surgery, with morbidity and mortality comparable to the reports of laparotomy surgery.

Mioma en remanente cervical tras histerectomía supracervical laparoscópica, presentación de un caso y revisión de la literatura / Myoma in cervical remnant after laparoscopic supracervical hysterectomy, case report and literature review

INTRODUCCIÓN: Los leiomiomas uterinos son el tumor pélvico más frecuente en la mujer, derivan de las células musculares lisas del miometrio y pueden localizarse en cualquiera de las porciones uterinas. Se clasifican según su relación con las diferentes capas del útero mediante la clasificación de la FIGO. Pueden ser asintomáticos o producir síntomas como sangrado, problemas reproductivos o dolor por compresión de estructuras vecinas. El tratamiento puede ser médico o quirúrgico, teniendo dentro de este último grupo, la posibilidad de realizar una miomectomía o una histerectomía total o subtotal. La histerectomía subtotal permite mantener el cérvix uterino, de tal forma que la técnica quirúrgica es más sencilla, sin embargo, requiere de la morcelación de la pieza para su extracción; mientras que la histerectomía total elimina el riesgo de recidiva de la patología uterocervical, aunque precisa de una mayor curva de aprendizaje. CASO CLÍNICO: Presentamos el caso de una paciente de 52 años a la que se le realizó una histerectomía supracervical laparoscópica por miomas. Posteriormente, se objetivó la aparición de un nuevo mioma en el remanente cervical, que requirió de una traquelectomía vía vaginal. CONCLUSIÓN: La histerectomía subtotal laparoscópica en úteros con múltiples miomas puede tener como efecto adverso la recidiva miomatosa en el cérvix o la aparición de miomas parasitarios secundarios a la morcelación uterina no estanca. Además, implica continuar con el cribado para la prevención del cáncer de cérvix uterino.

BACKGROUND: Uterine leiomyomas are the most frequent pelvic tumor in women. They derive from smooth muscle cells of the myometrium and can be in any of the uterine parts. They are classified according to their relationship with the different layers of the uterus by the FIGO classification. Uterine leiomyomas can be asymptomatic or produce symptoms such as compression pain, reproductive problems and metrorrhagia. The treatment can be medical or surgical. Within this last group there is the possibility of performing a myomectomy or a total or subtotal hysterectomy. The subtotal hysterectomy allows the uterine cervix to be maintained and therefore the surgical technique is simpler. However, it requires the morcellation of the piece for its removal. Alternatively, total hysterectomy eliminates the risk of recurrence of uterocervical pathology, but this procedure presents a steeper learning curve. CLINICAL CASE: We present the case of a patient of 52 years who underwent a laparoscopic supracervical hysterectomy for myomas. Subsequently, the appearance of a new myoma in the cervical remnant was observed, which required a vaginal trachelectomy. CONCLUSION: Laparoscopic subtotal hysterectomy in myomatous uterus can have as an adverse effect myomatous recurrence in the cervix or the appearance of parasitic myomas secondary to non-contained uterine morcellation. In addition, it involves continuing screening for the prevention of cervical cancer.
