Revisional surgery for persistent dysphagia plus Roux Y gastric bypass robot-assisted in a patient with obesity. About a case.

This case study presents a female patient with progressive dysphagia for solids, heartburn, and obesity that proved refractory to clinical management. Imagenological diagnosis revealed esophageal stenosis and achalasia. Furthermore, metabolic syndrome was established. We proposed intervention through esophagogastric reconstruction due to stenosis, revision of cardiomyotomy and robotic gastric bypass revealing scar tissue and fibrosis on the anterior aspect of the stomach resulting from prior fundoplication surgery. The patient underwent esophagogastric reconstruction due to adhesion bands which conditioned partial angulation of the gastroesophageal junction, cardiomyotomy revision, anterior and posterior hiatal plasty, and Roux Y Gastric Bypass assisted by a robot without complications. The intervention resulted in significant improvement in postoperative symptoms. This case highlights the importance of considering the probability of mechanical obstruction due to postsurgical adhesions in the initial evaluation of recurrent and persistent dysphagia, with surgical reintervention being the ideal option for resolution.

Pressure dynamics of the esophagogastric junction at rest and during inspiratory maneuvers after Nissen fundoplication.

Low sphincter pressure and inability of the crural diaphragm to elevate it at the esophagogastric junction are important pathophysiological mechanisms of gastroesophageal reflux disease (GERD). The object of this study was to depict how Nissen fundoplication changed the resting and inspiratory pressures of the anti-reflux barrier. We selected 14 patients (eight males; mean age 42.7 years; mean body mass index 27.8) for surgery. They answered symptoms questionnaires and underwent high-resolution manometry (HRM) before and 6 months after Nissen fundoplication. We used a standard manometric protocol (resting and liquid swallows) and assessment of esophagogastric junction (EGJ) pressure metrics during standardized forced inspiratory maneuvers against increasing loads (Threshold Maneuvers). We used the Wilcoxon test for comparison of pre and postoperative data. After fundoplication, heartburn and regurgitation scores diminished remarkably (from 4.5 and 2, respectively, to zero; P = 0.002 and P = 0.0005, respective medians). Also, the median expiratory EGJ pressure had a significant increase from 8.1 to 18.1 mmHg (P = 0.002), while mean respiratory pressure and EGJ contractility integral (EGJ-CI) increased without statistical significance (P = 0.064 and P = 0.06, respectively). Axial EGJ displacement was lower after fundoplication. The EGJ relaxation pressure (P = 0.001), the mean distal esophageal intrabolus pressure (P = 0.01) and the distal latency (P = 0.017) increased after fundoplication. There was a reduction in the contraction front velocity (P = 0.043). During evaluation with standardized inspiratory maneuvers, the inspiratory EGJ pressures (under loads of 12, 24, 36 and 48 cmH2O) were lower after surgery for all loads (median for load 12 cmH2O: 145.6 vs. 102.7 mmHg; P = 0.004). Fundoplication and hiatal closure increased the expiratory EGJ pressure and promoted a great GERD symptom relief. The surgery seemed to overcompensate a reduced EGJ mobility and inspiratory pressure.

Endoscopic ablation combined with fundoplication plus acid suppression-duodenal diversion procedure for long segment barrett´s esophagus: early and long-term outcome / Ablação endoscópica combinada com fundoplicatura associada a diversão duodenal no esôfago de barrett longo: resultados precoce e de longo prazo

ABSTRACT BACKGROUND: The addition of endoscopic ablative therapy plus proton pump inhibitors or fundoplication is postulated for the treatment of patients with long-segment Barrett´s esophagus (LSBE); however, it does not avoid acid and bile reflux in these patients. Fundoplication with distal gastrectomy and Roux-en-Y gastrojejunostomy is proposed as an acid suppression-duodenal diversion procedure demonstrating excellent results at long-term follow-up. There are no reports on therapeutic strategy with this combination. AIMS: To determine the early and long-term results observed in LSBE patients with or without low-grade dysplasia who underwent the acid suppression-duodenal diversion procedure combined with endoscopic therapy. METHODS: Prospective study including patients with endoscopic LSBE using the Prague classification for circumferential and maximal lengths and confirmed by histological study. Patients were submitted to argon plasma coagulation (21) or radiofrequency ablation (31). After receiving treatment, they were monitored at early and late follow-up (5-12 years) with endoscopic and histologic evaluation. RESULTS: Few complications (ulcers or strictures) were observed after the procedure. Re-treatment was required in both groups of patients. The reduction in length of metaplastic epithelium was significantly better after radiofrequency ablation compared to argon plasma coagulation (10.95 vs 21.15 mms for circumferential length; and 30.96 vs 44.41 mms for maximal length). Intestinal metaplasia disappeared in a high percentage of patients, and histological long-term results were quite similar in both groups. CONCLUSIONS: Endoscopic procedures combined with fundoplication plus acid suppression with duodenal diversion technique to eliminate metaplastic epithelium of distal esophagus could be considered a good alternative option for LSBE treatment.

RESUMO RACIONAL: A adição de terapia ablativa endoscópica associado a inibidores da bomba de prótons ou fundoplicatura tem sido postulada para o tratamento de pacientes com esôfago de Barrett de segmento longo (EBSL), no entanto, essa conduta não evita o refluxo ácido/biliar nesses pacientes. A fundoplicatura com gastrectomia distal e gastrojejunostomia em Y de Roux (FGD-Y) foi proposta como procedimento de supressão de ácido, demonstrando excelentes resultados no seguimento a longo prazo. Não há relatos na literature com a combinação dessa estratégia terapêutica. OBJETIVOS: Determinar os resultados precoces e a longo prazo observados em pacientes com EBSL com ou sem dysplasia de baixo grau, submetidos a FGD-Y, combinado com terapia endoscópica. MÉTODOS: Estudo prospectivo incluindo pacientes com EBSL, empregando a classificação de Praga, sendo o comprimento circunferencial (C) e máximo (M) e confirmado por estudo histológico. Os pacientes foram submetidos à coagulação com plasma de argônio (CPA, 21 pacientes) ou ablação por radiofrequência (ARF, 31 pacientes). Após o tratamento, eles foram seguidos precoce e tardiamente (5-12 anos), mediante avaliação endoscópica e histológica. RESULTADOS: Foram observadas poucas complicações após o procedimento (úlcera ou estenose). Re-tratamento foi necessário em ambos os grupos de pacientes. A redução do comprimento do epitélio metaplásico foi significativamente melhor após ARF em comparação com CPA (10,95 versus 21,15 mm para C e 30,96 versus 44,41 mm para M). A metaplasia intestinal desapareceu em elevada porcentagem de pacientes, e os resultados histológicos a longo prazo foram bastante semelhantes em ambos os grupos. CONCLUSÕES: Procedimentos endoscópicos combinados com fundoplicatura e gastrectomia distal e gastrojejunostomia em Y de Roux, para eliminar o epitélio metaplásico do esôfago distal podem ser considerados uma boa opção alternativa para o tratamento da EBSL.

Laparoscopic antireflux surgery: were old questions answered? partial or total fundoplication? / Cirurgia laparoscópica antirrefluxo: perguntas antigas foram respondidas? fundoplicatura parcial ou total?

ABSTRACT Laparoscopic total fundoplication is currently considered the gold standard for the surgical treatment of gastroesophageal reflux disease. Short-term outcomes after laparoscopic total fundoplication are excellent, with fast recovery and minimal perioperative morbidity. The symptom relief and reflux control are achieved in about 80 to 90% of patients 10 years after surgery. However, a small but clinically relevant incidence of postoperative dysphagia and gas-related symptoms is reported. Debate still exists about the best antireflux operation; during the last three decades, the surgical outcome of laparoscopic partial fundoplication (anterior or posterior) were compared to those achieved after a laparoscopic total fundoplication. The laparoscopic partial fundoplication, either anterior (180°) or posterior, should be performed only in patients with gastroesophageal reflux disease secondary to scleroderma and impaired esophageal motility, since the laparoscopic total fundoplication would impair esophageal emptying and cause dysphagia.

RESUMO A fundoplicatura total laparoscópica é considerada, atualmente, o padrão ouro para o tratamento cirúrgico da doença do refluxo gastroesofágico. Os resultados de curto prazo após a fundoplicatura total laparoscópica são excelentes, com recuperação rápida e morbidade perioperatória mínima. O alívio dos sintomas e o controle do refluxo são alcançados em cerca de 80 a 90% dos pacientes, 10 anos após a cirurgia. No entanto, é relatada uma incidência pequena, mas clinicamente relevante, de disfagia pós-operatória e sintomas relacionados a gases. Ainda existe debate sobre a melhor operação antirrefluxo e, nas últimas três décadas, os resultados cirúrgicos da fundoplicatura parcial laparoscópica (anterior ou posterior) foram comparados aos obtidos após uma fundoplicatura total laparoscópica. A fundoplicatura parcial laparoscópica, seja anterior (180°) ou posterior, deve ser realizada apenas em pacientes com doença do refluxo gastroesofágico secundária a esclerodermia e motilidade esofágica ineficiente, pois uma fundoplicatura total laparoscópica prejudicaria o esvaziamento esofágico e causaria disfagia.

Development of adenocarcinoma after radiofrequency ablation of barrett's esophagus associated to fundoplication and suppression-duodenal diversion procedure: a lesson to be learned / Adenocarcinoma em esôfago de barrett após ablação por radiofrequência associada a fundoplicatura e diversão duodenal

ABSTRACT Despite endoscopic eradication therapy being an effective and durable treatment for Barrett's esophagus-related neoplasia, even after achieving initial successful eradication, these patients remain at risk of recurrence and require ongoing routine examinations. Failure of radiofrequency ablation and argon plasma coagulation is reported in 10-20% of cases.

RESUMO Apesar de a terapia de erradicação endoscópica ser um tratamento eficaz e durável para a neoplasia relacionada ao esôfago de Barrett (BE), mesmo após a erradicação inicial bem-sucedida, esses pacientes permanecem em risco de recorrência e requerem exames de rotina contínuos. A falha na ablação por radiofrequência e na coagulação com plasma de argônio é relatada em 10-20% dos casos.

Esófago porcino: modelo ex vivo de entrenamiento laparoscópico para la miotomía de Heller y funduplicatura de Dor / Porcine esophagus: ex vivo laparoscopic training model for Heller's myotomy and Dor's funduplication

El dominio de procedimientos avanzados en laparoscopia es fundamental para los cirujanos, por ello el entrenamiento es imprescindible. La miotomía de Heller y funduplicatura de Dor requieren el desarrollo de habilidades y destrezas para realizar la cirugía de forma segura y eficaz, superar la curva de aprendizaje es un reto para el cirujano en formación, por lo que se propone el esófago porcino como modelo ex vivo de entrenamiento laparoscópico, con el fin de permitir desarrollar las habilidades necesarias y así llevar a cabo con éxito el procedimiento quirúrgico.Objetivo : Aplicar el esófago porcino como modelo ex vivo para el entrenamiento laparoscópico de la miotomía de Heller y funduplicatura de Dor.Métodos : Se realizó un estudio prospectivo, experimental y longitudinal, aplicado en un período de 17 semanas, en sesiones de 1 hora cada una, una sesión por semana.Resultados : Se llevaron a cabo 17 prácticas realizadas por el autor, evaluadas por cirujanos expertos, observando un aumento de la puntuación obtenida en la escala GOALS y disminución del tiempo de ejecución a medida que aumentaba el número de prácticas con una correlación altamente significativa, según la tau-B de Kendall (p=0,000).Conclusión : El modelo ex vivo permitió recrear la mayoría de los pasos quirúrgicos y demostró ser una herramienta útil y valiosa, disminuyendo el tiempo de ejecución del procedimiento y aumentando significativamente las habilidades laparoscópicas(AU)

Mastery of advanced procedures in laparoscopy is important for surgeons, therefore training is essential. Heller's myotomy and Dor's fundoplication require the development of abilities and skills to perform the surgery safely and effectively, overcoming the learning curve is a challenge for the surgeon in training, so the porcine esophagus is proposed as an ex vivo model of laparoscopic training in order to develop the necessary skills to successfully carry out the surgical procedure. Objective: To apply the porcine esophagus as an ex vivo model for laparoscopic training of Heller's myotomy and Dor's fundoplication. Methods: A prospective, experimental and longitudinal study was carried out, applied by the authors in a period of 17 weeks, in sessions of 1 hour each, one session per week. Results: 17 practices carried out by the author were carried out, evaluated by expert surgeons, observing an increase in the score obtained on the GOALS scale and a decrease in execution time as the number of practices with a high significant influence increase, according to Kendall's tau-B (p=0.000). Conclusion: The ex vivo model allowed recreating most of the surgical steps and stood out as a useful and valuable tool, decreasing the execution time of the procedure and significantly increasing laparoscopic skills(AU)

Peroral endoscopic myotomy vs laparoscopic myotomy and partial fundoplication for esophageal achalasia: A single-center randomized controlled trial.

BACKGROUND: Achalasia is a rare benign esophageal motor disorder characterized by incomplete relaxation of the lower esophageal sphincter (LES). The treatment of achalasia is not curative, but rather is aimed at reducing LES pressure. In patients who have failed noninvasive therapy, surgery should be considered. Myotomy with partial fundoplication has been considered the first-line treatment for non-advanced achalasia. Recently, peroral endoscopic myotomy (POEM), a technique that employs the principles of submucosal endoscopy to perform the equivalent of a surgical myotomy, has emerged as a promising minimally invasive technique for the management of this condition. AIM: To compare POEM and laparoscopic myotomy and partial fundoplication (LM-PF) regarding their efficacy and outcomes for the treatment of achalasia. METHODS: Forty treatment-naive adult patients who had been diagnosed with achalasia based on clinical and manometric criteria (dysphagia score ≥ II and Eckardt score > 3) were randomized to undergo either LM-PF or POEM. The outcome measures were anesthesia time, procedure time, symptom improvement, reflux esophagitis (as determined with the Gastroesophageal Reflux Disease Questionnaire), barium column height at 1 and 5 min (on a barium esophagogram), pressure at the LES, the occurrence of adverse events (AEs), length of stay (LOS), and quality of life (QoL). RESULTS: There were no statistically significant differences between the LM-PF and POEM groups regarding symptom improvement at 1, 6, and 12 mo of follow-up (P = 0.192, P = 0.242, and P = 0.242, respectively). However, the rates of reflux esophagitis at 1, 6, and 12 mo of follow-up were significantly higher in the POEM group (P = 0.014, P < 0.001, and P = 0.002, respectively). There were also no statistical differences regarding the manometry values, the occurrence of AEs, or LOS. Anesthesia time and procedure time were significantly shorter in the POEM group than in the LM-PF group (185.00 ± 56.89 and 95.70 ± 30.47 min vs 296.75 ± 56.13 and 218.75 ± 50.88 min, respectively; P = 0.001 for both). In the POEM group, there were improvements in all domains of the QoL questionnaire, whereas there were improvements in only three domains in the LM-PF group. CONCLUSION: POEM and LM-PF appear to be equally effective in controlling the symptoms of achalasia, shortening LOS, and minimizing AEs. Nevertheless, POEM has the advantage of improving all domains of QoL, and shortening anesthesia and procedure times but with a significantly higher rate of gastroesophageal reflux.

Laparoscopic total fundoplication is superior to medical treatment for reducing the cancer risk in Barrett's esophagus: a long-term analysis.

The present study aims to compare the effectiveness of surgical and medical therapy in reducing the risk of cancer in Barrett's esophagus in a long-term evaluation. A prospective cohort was designed that compared Barrett's esophagus patients submitted to medical treatment with omeprazole or laparoscopic Nissen fundoplication. The groups were compared using propensity score matching paired by Barrett's esophagus length. A total of 398 patients met inclusion criteria. There were 207 patients in the omeprazole group (Group A) and 191 in the total fundoplication group (Group B). After applying the propensity score matching paired by Barrett's esophagus length, the groups were 180 (Group A) and 190 (Group B). Median follow-up was 80 months. Group B was significantly superior for controlling GERD symptoms. Group B was more efficient than Group A in promoting Barrett's esophagus regression or blocking its progression. Group B was more efficient than Group A in preventing the development of dysplasia and cancer. Logistic regression was performed for the outcomes of adenocarcinoma and dysplasia. Age and body mass index were used as covariates in the logistic regression models. Even after regression analysis, Group B was still superior to Group A to prevent esophageal adenocarcinoma or dysplasia transformation (odds ratio [OR]: 0.51; 95% confidence interval [CI]: 0.27-0.97, for adenocarcinoma or any dysplasia; and OR: 0.26; 95% CI: 0.08-0.81, for adenocarcinoma or high-grade dysplasia). Surgical treatment is superior to medical management, allowing for better symptom control, less need for reflux medication use, higher regression rate of the columnar epithelium and intestinal metaplasia, and lower risk for progression to dysplasia and cancer.

Gastroesophageal Reflux Disease and Idiopathic Lung Fibrosis. From Heartburn to Lung Transplant, and Beyond.

Idiopathic pulmonary fibrosis (IPF) and gastroesophageal reflux disease (GERD) are undoubtedly related. Even though it is not clear yet which one is the primary disease, they certainly interact increasing each other's severity. Symptoms are unreliable to diagnose GERD in patients with IPF, and objective evaluation with pH monitoring and/or bronchoalveolar lavage analysis is mandatory. Pharmacological treatment with proton pump inhibitors (PPIs) may bring control of IPF in few patients, but PPIs do not control reflux but just change the pH of the gastric refluxate. Surgical therapy based on a fundoplication is safe and effective as it controls any type of reflux, independently from the pH of the gastric refluxate. In patients waiting for lung transplantation (if they can tolerate a laparoscopic operation under general anesthesia), a fundoplication before the operation might block the progression of IPF, while after transplantation it might prevent rejection by preventing the bronchiolitis obliterans syndrome.

Peroral endoscopic myotomy for the treatment of achalasia in the Unified Healthcare System (SUS): results of a short-term / Miotomia endoscópica peroral para o tratamento de acalásia no Sistema Único de Saúde (SUS): resultados de seguimento no curto-prazo

ABSTRACT Introduction: achalasia is a chronic disease. Since there is no curative treatment, diagnosed patients have pharmacological and/or surgical techniques available, aimed at minimizing the condition. POEM appears as a promising new type of palliative treatment with good rates of symptom improvement. Objective: evaluate the profile of POEM at the Clinical Hospital of the Federal University of Pernambuco (HC - UFPE) and correlate it with the world scenario. Methods: data collection was performed retrospectively from September 2017 to October 2019 with all patients undergoing POEM at the HC - UFPE. Sociodemographic, clinical, and hospital variables were evaluated before and three months after the procedure. Results: of 27 patients (52.41 ± 19.24 years old) who underwent the procedure, 66.7% had idiopathic etiology and 33.3% had etiology secondary to Chagas disease. 48% patients underwent previous procedures, of which seven used some type of medication for symptom control, two underwent pneumatic endoscopic dilation, and four underwent Heller cardiomyotomy with partial fundoplication. 62.5% of the evaluated patients had type II achalasia before the procedure. Seven (25.9%) patients presented the following adverse events: four presented bleeding, two pneumoperitoneum, and one both complications, all being treated conservatively. The Eckardt score reduced from 8.37 ± 1.45 to 0.85 ± 1.06 (p-value <0.001). Conclusion: clinical improvement of symptoms and the patient profile followed the worldwide trend, with emphasis on the etiology secondary to Chagas disease, endemic in Brazil. Gastroesophageal reflux remains the main post-operative symptom.

RESUMO Introdução: a acalasia é uma doença crônica. Por não haver tratamento curativo, os pacientes diagnosticados dispõem de técnicas farmacológicas e/ou cirúrgicas, visando minimizar o quadro. A POEM surge como um novo tipo de tratamento paliativo promissor com boas taxas de melhora dos sintomas. Objetivo: avaliar o perfil das POEM realizadas no Hospital das Clínicas da Universidade Federal de Pernambuco (HC - UFPE) e correlacioná-lo com o cenário mundial. Métodos: a coleta de dados foi realizada retrospectivamente no período de setembro de 2017 a outubro de 2019 com todos os pacientes submetidos a POEM no HC - UFPE. Variáveis sociodemográficas, clínicas e hospitalares foram avaliadas antes e três meses após o procedimento. Resultados: total de 27 pacientes (52,41 ± 19,24 anos) que realizaram o procedimento, 66,7% com etiologia idiopática e 33,3% com etiologia secundária à doença de Chagas. 48% tinham sido submetidos a procedimentos prévios, dos quais sete usaram algum tipo de medicamento para controle dos sintomas, dois foram submetidos à dilatação endoscópica pneumática e quatro à cardiomiotomia a Heller com fundoplicatura parcial. 62,5% dos pacientes avaliados tinham acalasia tipo ii antes do procedimento. Sete (25,9%) apresentaram eventos adversos: quatro sangramentos, dois pneumoperitônio e um ambas as complicações, todos foram tratados de forma conservadora. O escore de Eckardt reduziu de 8,37 ± 1,45 para 0,85 ± 1,06 (valor de p<0,001). Conclusão: melhora clínica e o perfil dos pacientes acompanhou a tendência mundial, destaque para a etiologia secundária à doença de Chagas, endêmica no Brasil. O refluxo gastroesofágico continua sendo o principal sintoma pós-operatório.

Laparoscopic redo fundoplication alone, redo nissen fundoplication, or toupet fundoplication combined with roux-en-y distal gastrectomy for treatment of failed nissen fundoplication / Refazer fundoplicatura laparoscópica, refazer fundoplicatura a nissen ou toupet combinada com gastrectomia distal em y-roux para tratamento de recidiva após fundoplicatura a nissen

ABSTRACT BACKGROUND: Laparoscopic Nissen fundoplication fails to control the gastroesophageal reflux in almost 15% of patients, and most of them must be reoperated due to postoperative symptoms. Different surgical options have been suggested. AIMS: This study aimed to present the postoperative outcomes of patients submitted to three different procedures: redo laparoscopic Nissen fundoplication alone (Group A), redo laparoscopic Nissen fundoplication combined with distal gastrectomy (Group B), or conversion to laparoscopic Toupet combined with distal gastrectomy with Roux-en-Y gastrojejunostomy (Group C). METHODS: This is a prospective study involving 77 patients who were submitted initially to laparoscopic Nissen fundoplication and presented recurrence of gastroesophageal reflux after the operation. They were evaluated before and after the reoperation with clinical questionnaire and objective functional studies. After reestablishing the anatomy of the esophagogastric junction, a surgery was performed. None of the patients were lost during follow-up. RESULTS: Persistent symptoms were observed more frequently in Group A or B patients, including wrap stricture, intrathoracic wrap, or twisted fundoplication. In Group C, recurrent symptoms associated with this anatomic alteration were infrequently observed. Incompetent lower esophageal sphincter was confirmed in 57.7% of patients included in Group A, compared to 17.2% after Nissen and distal gastrectomy and 26% after Toupet procedure plus distal gastrectomy. In Group C, despite the high percentage of patients with incompetent lower esophageal sphincter, 8.7% had abnormal acid reflux after surgery. CONCLUSIONS: Nissen and Toupet procedures combined with Roux-en-Y distal gastrectomy are safe and effective for the management of failed Nissen fundoplication. However, Toupet technique is preferable for patients suffering from mainly dysphagia and pain.

RESUMO RACIONAL: A fundoplicatura de Nissen laparoscópica falha em controlar o refluxo gastroesofágico em quase 15% dos pacientes e a maioria deles deve ser reoperada devido aos sintomas. Diferentes técnicas cirúrgicas têm sido sugeridas. OBJETIVOS: Apresentar os resultados pós-operatórios de pacientes submetidos a 3 procedimentos diferentes: Reoperação e fundoplicatura de Nissen laparoscópica apenas (Grupo A), reoperação e fundoplicatura de Nissen laparoscópica combinado com gastrectomia distal (Grupo B) ou reoperação e conversão para Toupet laparoscópico combinado com gastrectomia distal e reconstrução em Y-Roux (Grupo C). MÉTODOS: estudo prospectivo incluindo 77 pacientes submetidos inicialmente a fundoplicatura de Nissen laparoscópica que apresentaram recidiva do refluxo gastroesofágico após a operação. Eles foram avaliados antes e após a reoperação com questionário clínico e estudos funcionais específicos. Reestabelecida a anatomia da junção esôfago-gástrica, procedeu-se às referidas cirurgias. Nenhum paciente perdeu seguimento. RESULTADOS: Os sintomas persistentes foram observados com maior frequência nos pacientes dos Grupos A ou B, associados à estenose da fundoplicatura, fundoplicatura intratorácico ou fundoplicatura torcida. No Grupo C, os sintomas recorrentes associados a essa alteração anatômica foram observados com pouca frequência. Esfincter esofágico inferior incompetente foi confirmado em 57,7% dos pacientes pertencentes ao Grupo A em comparação com 17,2% após fundoplicatura de Nissen laparoscópica combinado com gastrectomia distal, e 26% após a Toupet laparoscópico combinado com gastrectomia distal e reconstrução em Y-Roux. Nesse grupo, apesar do alto percentual de pacientes com esfincter esofágico inferior incompetente, 8,7% apresentaram refluxo ácido anormal após a cirurgia. CONCLUSÕES: As técnicas de Nissen ou Toupet combinados com a gastrectomia distal em Y de Roux são seguras e eficazes para o manejo da falha da fundoplicatura a Nissen. A técnica de Toupet é preferível para pacientes que sofrem principalmente com disfagia e dor.

Primary repair: damage control surgery in esophageal trauma.

Esophageal trauma is a rare but life-threatening event associated with high morbidity and mortality. An inadvertent esophageal perforation can rapidly contaminate the neck, mediastinum, pleural space, or abdominal cavity, resulting in sepsis or septic shock. Higher complications and mortality rates are commonly associated with adjacent organ injuries and/or delays in diagnosis or definitive management. This article aims to delineate the experience obtained by the Trauma and Emergency Surgery Group (CTE) of Cali, Colombia, on the surgical management of esophageal trauma following damage control principles. Esophageal injuries should always be suspected in thoracoabdominal or cervical trauma when the trajectory or mechanism suggests so. Hemodynamically stable patients should be radiologically evaluated before a surgical correction, ideally with computed tomography of the neck, chest, and abdomen. While hemodynamically unstable patients should be immediately transferred to the operating room for direct surgical control. A primary repair is the surgical management of choice in all esophageal injuries, along with endoscopic nasogastric tube placement and immediate postoperative care in the intensive care unit. We propose an easy-to-follow surgical management algorithm that sticks to the philosophy of "Less is Better" by avoiding esophagostomas.

El trauma esofágico es un evento poco frecuente pero potencialmente mortal. Una perforación esofágica inadvertida puede ocasionar la rápida contaminación del cuello, el mediastino, el espacio pleural o la cavidad abdominal, lo cual puede resultar en sepsis o choque séptico. Las complicaciones y la mortalidad aumentan con el retraso en el diagnóstico o manejo definitivo, y la presencia de lesiones asociadas. El objetivo del presente artículo es describir la experiencia adquirida por el grupo de cirugía de Trauma y Emergencias (CTE) de Cali, Colombia en el manejo del trauma de esófago de acuerdo con los principios de la cirugía de control de daños. Las lesiones esofágicas deben sospecharse en todo trauma toraco-abdominal o cervical en el que el mecanismo o la trayectoria de la lesión lo sugieran. El paciente hemodinámicamente estable se debe estudiar con imágenes diagnósticas antes de la corrección quirúrgica del defecto, idealmente por medio de tomografía computarizada del cuello, tórax y abdomen con contraste endovenoso. Mientras que en el paciente hemodinámicamente inestable se debe explorar y controlar la lesión. El reparo primario es el manejo quirúrgico de elección, con la previa colocación de una sonda nasogástrica y el seguimiento postoperatorio estricto en la unidad de cuidado intensivo. Se propone un algoritmo de manejo quirúrgico que resulta fácil de seguir y adopta la premisa "Menos es Mejor" evitando realizar derivaciones esofágicas.

Utilidad del dispositivo de potenciación del esfínter esofágico distal (LINX®) para pacientes con reflujo gastroesofágico / Usefulness of the distal esophageal sphincter enhancement device (LINX®) for patients with gastroesophageal reflux

Resumen La fundoplicatura de Nissen laparoscópica (FNL) es el gold standard del tratamiento quirúrgico de pacientes con reflujo gastroesofágico patológico (RGE), con perfil de seguridad y resultados a largo plazo satisfactorios en un 80%. En la última década, se ha propuesto el uso de un dispositivo de potenciación del esfínter esofágico inferior (MSA) comercializado como LINX® (de Ethicon, Johnson & Johnson), como alternativa a la cirugía antirreflujo. El dispositivo consiste en una cadena expansible de cuentas de titanio con un núcleo magnético diseñadas para aumentar el tono del esfínter esofágico inferior (EEI) y evitar su relajación inadecuada. Los resultados preliminares han sido alentadores, sin embargo, no está exento de complicaciones. Las indicaciones más aceptadas son: RGE con motilidad esofágica normal y sin esofagitis erosiva, hernia hiatal < 3 cm, IMC <35 kg/m2 y pacientes sin cirugías gastroesofágicas previas. Se instala por vía laparoscópica. Los efectos adversos más importantes son: disfagia con necesidad de dilataciones endoscópicas, y, retiro del dispositivo, entre 1% y 7% a los 2,5 años. La mayoría de los estudios tienen limitaciones metodológicas, conflictos de interés, falta de resultados objetivos y seguimientos a largo plazo, impidiendo llegar a conclusiones extrapolables respecto a la eficacia del MSA.

Laparoscopic Nissen Fundoplication (LNF) is the gold standard of surgical treatment for patients with Gastroesophageal Reflux Disease (GER), with safety profile and long term results satisfactory in 80%. In the last decade, the use of a Lower Esophageal Sphincter Enhancement Device (LESD), marketed as LINX® (from Ethicon, Johnson & Johnson), has been proposed as an alternative to Anti-Reflux Surgery. The device consists of an expandable chain of titanium beads with a magnetic core designed to increase the tone of the lower esophageal sphincter (LES) and prevent its improper relaxation. Preliminary results have been encouraging; however, it is not without complications. The most accepted indications are: GER with normal esophageal motility and without erosive esophagitis, hiatal hernia < 3 cm, BMI <35 kg/m2, and patients without previous gastroesophageal surgeries. It is installed by laparoscopy. The most important adverse effects are: dysphagia with the need for endoscopic dilations, and, removal of the device, between 1 and 7% at 2.5 years. Most of the studies have methodological limitations, conflicts of interest, lack of objective results and long-term follow-up, preventing the reaching of extrapolable conclusions regarding the efficacy of MSA.

Primary repair: damage control surgery in esophageal trauma / El reparo primario: el control de daños en el trauma de esófago

Abstract Esophageal trauma is a rare but life-threatening event associated with high morbidity and mortality. An inadvertent esophageal perforation can rapidly contaminate the neck, mediastinum, pleural space, or abdominal cavity, resulting in sepsis or septic shock. Higher complications and mortality rates are commonly associated with adjacent organ injuries and/or delays in diagnosis or definitive management. This article aims to delineate the experience obtained by the Trauma and Emergency Surgery Group (CTE) of Cali, Colombia, on the surgical management of esophageal trauma following damage control principles. Esophageal injuries should always be suspected in thoracoabdominal or cervical trauma when the trajectory or mechanism suggests so. Hemodynamically stable patients should be radiologically evaluated before a surgical correction, ideally with computed tomography of the neck, chest, and abdomen. While hemodynamically unstable patients should be immediately transferred to the operating room for direct surgical control. A primary repair is the surgical management of choice in all esophageal injuries, along with endoscopic nasogastric tube placement and immediate postoperative care in the intensive care unit. We propose an easy-to-follow surgical management algorithm that sticks to the philosophy of "Less is Better" by avoiding esophagostomas.

Resumen El trauma esofágico es un evento poco frecuente pero potencialmente mortal. Una perforación esofágica inadvertida puede ocasionar la rápida contaminación del cuello, el mediastino, el espacio pleural o la cavidad abdominal, lo cual puede resultar en sepsis o choque séptico. Las complicaciones y la mortalidad aumentan con el retraso en el diagnóstico o manejo definitivo, y la presencia de lesiones asociadas. El objetivo del presente artículo es describir la experiencia adquirida por el grupo de cirugía de Trauma y Emergencias (CTE) de Cali, Colombia en el manejo del trauma de esófago de acuerdo con los principios de la cirugía de control de daños. Las lesiones esofágicas deben sospecharse en todo trauma toraco-abdominal o cervical en el que el mecanismo o la trayectoria de la lesión lo sugieran. El paciente hemodinámicamente estable se debe estudiar con imágenes diagnósticas antes de la corrección quirúrgica del defecto, idealmente por medio de tomografía computarizada del cuello, tórax y abdomen con contraste endovenoso. Mientras que en el paciente hemodinámicamente inestable se debe explorar y controlar la lesión. El reparo primario es el manejo quirúrgico de elección, con la previa colocación de una sonda nasogástrica y el seguimiento postoperatorio estricto en la unidad de cuidado intensivo. Se propone un algoritmo de manejo quirúrgico que resulta fácil de seguir y adopta la premisa "Menos es Mejor" evitando realizar derivaciones esofágicas.

Fundoplication versus oral proton pump inhibitors for gastroesophageal reflux disease: a systematic review and meta-analysis of randomized clinical trials.

Gastroesophageal reflux disease (GERD) is a widely studied and highly prevalent condition. However, few are reported about the exact efficacy and safety of fundoplication (FPT) compared to oral intake proton-pump inhibitors (PPI). This systematic review and meta-analysis of randomized clinical trials (RCT) aims to compare PPI and FPT in relation to the efficacy, as well as the adverse events associated with these therapies. Search carried out in June 2020 was conducted on Medline, Cochrane, EMBASE and LILACS. Selection was restricted to RCT comparing PPI and FPT (open or laparoscopic) in GERD patients. Certainty of evidence and risk of bias were assessed with GRADE Pro and with Review Manager Version 5.4 bias assessment tool. Ten RCT were included. Meta-analysis showed that heartburn (RD = - 0.19; 95% CI = - 0.29, - 0.09) was less frequently reported by patients that underwent FPT. Furthermore, patients undergoing surgery had greater pressure on the lower esophageal sphincter than those who used PPI (MD = 7.81; 95% CI 4.79, 10.83). Finally, FPT did not increase significantly the risk for adverse events such as postoperative dysphagia and impaired belching. FPT is a more effective therapy than PPI treatment for GERD, without significantly increasing the risk for adverse events. However, before indicating a possible surgical approach, it is extremely important to correctly assess and select the patients who would benefit from FPT to ensure better results.
