ABSTRACT

BACKGROUND: Although vertical banded gastroplasty (VBG) was endorsed by the 1991 National Institutes of Health Consensus Conference for the treatment of morbid obesity, it has largely been abandoned owing to the poor long-term weight loss and band-related complications. The objective of the present study was to review the outcomes of patients who had undergone laparoscopic conversion of VBG to Roux-en-Y gastric bypass (RYGB) for weight loss or dysphagia and gastroesophageal reflux. METHODS: A retrospective review of prospectively collected data from all patients who had undergone revision of VBG to RYGB was performed. The data on the symptoms, weight loss, co-morbidities, and complications were collected. RESULTS: From July 1999 to April 2010, 2397 bariatric procedures were performed. Of these, 105 (4.4%) were laparoscopic revisions of previous VBG to RYGB. Of the 105 patients, 103 had undergone open VBG and 2 laparoscopic VBG. Of the 105 patients, 97 were women and 8 were men. The average patient age was 49 years (range 23-71). The median preoperative body mass index was 42 kg/m(2) (range 20-72). Short- and long-term complications occurred in 40 patients (38%). No patients died. The median length of stay was 2 days. At an average follow-up of 31 months (range 1-96), the median percentage of excess weight loss was 47% (range -24% to 138%). The median decrease in body mass index was 8 kg/m(2) (range -6 to 30). Dysphagia had improved or resolved in 100%. Gastroesophageal reflux disease had improved or resolved in 95%. Diabetes had improved or went into remission in 90%. Hypertension had improved or resolved in 62%. Obstructive sleep apnea had improved or resolved in 96%. CONCLUSION: The results of our study have shown that laparoscopic revision of VBG to RYGB is a feasible procedure that can provide acceptable weight loss and reversal of weight-related co-morbidities. Complications were common after revisional bariatric surgery.

ABSTRACT

BACKGROUND: Immunocompromised patients are at high risk of medical complications. Immunosuppression might be a relative contraindication to bariatric surgery. We describe our experience with immunosuppressed patients undergoing bariatric surgery and review the safety, efficacy, results, and outcomes. METHODS: We performed a retrospective review of prospectively collected data. All patients taking long-term immunosuppressive medications or with a diagnosis of an immunosuppressive condition were included in this study. Data on weight loss, co-morbidities, complications, and postoperative immunosuppression were collected. RESULTS: From July 1999 to February 2008, 1566 patients underwent bariatric surgery. Of these 1566 patients, 61 (3.9%) were taking immunosuppressive medications or had an immunosuppressive condition. Of these 61 patients, 49 were taking immunosuppressive medications for asthma, autoimmune disorders, endocrine deficiency, or chronic inflammatory disorders. The medications included oral, inhaled, and topical glucocorticoids for 39 patients and other immunosuppressive or disease-modifying antirheumatic drugs for 24 patients. The bariatric procedures included laparoscopic Roux-en-Y gastric bypass in 55, laparoscopic revisional procedures in 5, and laparoscopic sleeve gastrectomy in 1. No patient died perioperatively. A total of 26 complications occurred in 20 patients. The average percentage of excess weight loss was 72% (range 20-109%) at 1 year postoperatively. At a median postoperative follow-up of 18 months (range 2-68.6), 25 (51%) of 49 patients no longer required immunosuppressive medications owing to improvement of their underlying disease. Obesity-related health problems (diabetes mellitus, hypertension, obstructive sleep apnea, gastroesophageal reflux disease, asthma) had resolved or improved in 80-100% of patients. CONCLUSION: The results of our study have shown that immunocompromised patients can safely undergo bariatric surgery with good weight loss results and improvement in co-morbidities. A large percentage of patients were able to discontinue immunosuppressive medications postoperatively.

ABSTRACT

BACKGROUND: Obesity is a risk factor for cancer and is associated with increased mortality from a number of malignancies. We describe our experience with bariatric surgery patients with a history of malignancy and review the safety and outcomes of bariatric surgery in patients with a history of cancer. METHODS: We performed a retrospective review of prospectively collected data from all patients diagnosed with a malignancy before, during, or after bariatric surgery. Data on weight loss, co-morbidities, and recurrence were collected. RESULTS: From July 1999 to February 2008, 1566 patients underwent bariatric surgery. Of these 1566 patients, 36 (2.3%) had a history of malignancy before they underwent bariatric evaluation and surgery, 4 (0.26%) were diagnosed with a malignancy during their preoperative evaluation, 2 of whom subsequently underwent bariatric surgery, and 2 had intraoperative findings suspicious for malignancy; bariatric surgery was completed in both cases. The evaluation revealed renal cell carcinoma and low-grade lymphoma, respectively. No procedures were aborted because of a suspicion of malignancy. Postoperatively, 16 patients (0.9%) were diagnosed with cancer, 3 of whom had a history of malignancy: 1 with metastatic renal cell, 1 with recurrent melanoma, and 1, who had had prostate cancer, with bladder cancer. CONCLUSION: A history of malignancy does not appear to be a contraindication for bariatric surgery as long as the life expectancy is reasonable. Screening for bariatric surgery might reveal the malignancy. Bariatric surgery does not seem to have a negative effect on the treatment of malignancies that are discovered in the postoperative period.

ABSTRACT

BACKGROUND: Previous studies have reported a high prevalence of Helicobacter pylori infection in patients undergoing Roux-en-Y gastric bypass (RYGB) and a greater incidence of anastomotic ulcer in patients positive for H. pylori, leading to recommendations for routine preoperative screening. Our hypotheses were that the prevalence of H. pylori in patients undergoing RYGB is similar to that of the general population and that preoperative H. pylori testing and treatment does not decrease the incidence of anastomotic ulcer or pouch gastritis. METHODS: A retrospective analysis of H. pylori serology, preoperative and postoperative endoscopy findings, and the development of anastomotic ulcer or erosive pouch gastritis was performed. All patients positive for H. pylori received treatment. Univariate parametric and nonparametric statistical tests, as well as multiple logistic regression analyses, were performed. RESULTS: A total of 422 LRYGB patients were included in the study. Of these patients, 259 (61.4%) were tested for H. pylori and 163 (38.6%) were not. Of the 259 patients, 58 (22.4%) tested positive for H. pylori, 197 (76.1%) tested negative, and 4 (1.5%) had an equivocal result. Postoperatively, 53 patients (12.6%) underwent upper endoscopy. Of these 53 patients, 19 (4.5%) had positive endoscopy findings for anastomotic ulcer (n = 16) or erosive pouch gastritis (n = 3). Five patients underwent biopsy at endoscopy; all biopsies were negative for H. pylori. No difference was found in the rate of positive endoscopy between patients tested preoperatively for H. pylori (5%) and patients not tested (3.7%). CONCLUSION: The results of our study have shown that the prevalence of H. pylori infection in patients undergoing RYGB is similar to that of the general population. Our study has shown that H. pylori testing does not lower the risk of anastomotic ulcer or pouch gastritis.

ABSTRACT

Antecentes: El tratamiento quirúrgico del prolapso rectal completo es controvertido. Se han descrito técnicas abdominales y perineales. La rectosigmoidectomía perineal (RSP) como tratamiento en el prolapso rectal completo. Lugar de aplicación: Hospital universitario. Diseño: retrospectivo, observacional. Población: 98 pacientes con prolapso rectal completo operados entre 1985 y 2005. Método: Análisis retrospectivo y descriptivo de los pacientes con prolapso rectal completo sometidos a una RSP en un Servicio de Coloproctología. Resultados: Se realizaron 106 cirugías en 98 pacientes (79 mujeres y 19 varones, edad promedio: 78 años). El seguimiento postoperatorio fue de 11 a 101 meses. El 72 por ciento presentaban incotinencia preoperatoria. En los primeros 30 pacientes la rectosigmoidectomía perineal se realizó sin la plástica del elevador, mientras que esta se utilizó en los siguientes, como parte del procedimiento. La incontinencia mejoró en el 43 por ciento y 84 por ciento respectivamente (P = 0,01). La estadía media intrahospitalaria fue de 3,5 días. La morbilidad postoperatoria fue del 14 por ciento: 3 hemorragias postoperatorias, 2 infecciones, 1 estenosis, 4 internaciones en UTI y 5 misceláneas. La mortalidad fue nula. El porcentaje de readmisión a los 30 días fue del 3 por ciento. La recidiva fue del 13,2 por ciento (n = 15). En 8 casos se repitió el procedimiento, en 2 resección/pexia y en 1 caso rectopexia con malla. Cuatro pacientes no se reoperaron. Conclusión: La RSP es un procedimiento seguro y efectivo en el tratamiento del prolapso rectal completo. La adición de una plástica del elevador al procedimiento mejora la incontinencia que suele presentarse en estos pacientes. (AU)

ABSTRACT

Gastric diverticula are extremely rare and may be congenital or acquired. Postgastrectomy formation of gastric diverticula has been attributed to outpouching through the weakened wall of the stomach. When symptomatic, gastric diverticula may cause pain, nausea, dysphagia, and vomiting. Gastric diverticula may also be associated with ectopic mucosa, ulcers, and neoplastic changes. We report a case of gastric cardia diverticulum that became symptomatic after laparoscopic Roux-en-Y gastric bypass. The patient was successfully treated with laparoscopic resection.

ABSTRACT

Antecedentes: Desde que Dallemagne presentó en 1991 el tratamiento laparoscópico de la enfermedad por reflujo gastroesofágico (ERGE), numerosos autores han observado, a pesar de los excelentes resultados y ventajas, un aumento de la disfagia postoperatoria. Objetivos: Dilucidar causas de disfagia postoperatoria; comprobar si la válvula realizada con el fundus, liberado por sección del ligamento frenogástrico posterior, mejora la disfagia; proponer un nuevo acceso retrogástrico. Lugar de aplicación: Hospital Público y práctica privada. Diseño: Estudio transversal analítico. Material y métodos: Desde julio de 1993 hasta diciembre de 2001 se intervino por laparoscopía 234 pacientes con ERGE. Clasificación de Savary: grado 1, 2 y 3: 193 (82,47 por ciento), grado 4: 5 (2,13 por ciento) y grado 5: 36 (15,38 por ciento). Se incluyen para su análisis: Grupo A) 96 pacientes en los que se realizó Nissen-Rossetti, Grupo B) 118 pacientes en los que se seccionó el ligamento frenogástrico posterior por acceso retrogástrico realizando Nissen. Se analiza la disfagia en ambos grupos. Resultados: Excelentes y buenos 91/96 (94,79 por ciento) pacientes en el grupo A y 115/118 (97,45 por ciento) en el grupo B. Se prsentó disfagia en 31/96 (32,29 por ciento) en grupo A y 7/118 (7,29 por ciento) en grupo B (p<0,001). Conclusiones: 1) La funduplicatura se debe realizar con las caras posterior y anterior del estómago en forma pareja y simétrica para evitar su rotación. 2) No se aconseja la técnica de Nissen-Rossetti. 3) La sección del ligamento frenogástrico posterior fue fundamental para la liberación de la cara posterior del fundus. 4) El acceso retrogástrico facilitó la sección del ligamento frenogástrico posterior (AU)
