Modified Nissen Fundoplication for Late Dumping Syndrome After Roux-en-Y Gastric Bypass.

INTRODUCTION: Postoperative dumping syndrome (DS) is a common complication after Roux-en-y gastric bypass (RYGB) for morbid obesity. DS is mostly treated conservatively through dietary or pharmacologic measures. In case of non-responding to or contraindication for conservative treatment, surgical intervention may be considered. Various procedures have been described, as there is currently no gold standard technique. We present a new approach by performing a modified Nissen fundoplication. CASE: A 34-year-old female consulted at our outpatient clinic. In her history, she had a laparoscopic RYGB 6 years earlier because of morbid obesity (BMI 37.6 kg/m2). Two years postoperatively, she developed a late DS, for which she was successfully treated with long-acting octreotide. Because of pregnancy wish, octreotide needed to be halted. A laparoscopic modified Nissen fundoplication was performed, creating a cuff around the oesophageal-gastric junction with the fundus of the remnant stomach. This slows down the passage of food through the gastric pouch. Postoperatively, the octreotide treatment was halted without any problems. At 6 months, the patient is still free of dumping complaints. DISCUSSION: Postoperative DS is a common complication after bariatric surgery. Dietary measures form the first treatment of DS, followed by pharmacologic treatment. Since octreotide is contraindicated in pregnancy, a surgical intervention was opted for. Our case is the first documented modified Nissen fundoplication to treat late postoperative DS after RYGB for morbid obesity. CONCLUSION: A laparoscopic modified Nissen fundoplication could be a promising surgical alternative in the treatment of late dumping syndrome after RYGB for morbid obesity.

Conversion of both Versions of Vertical Banded Gastroplasty to Laparoscopic Roux-en-Y Gastric Bypass: Analysis of Short-term Outcomes.

BACKGROUND: Conversional bariatric surgery has relatively high rates of complications. We aimed to analyze our single-center experience with patients requiring conversional laparoscopic Roux-en-Y gastric bypass (LRYGB) following a failed primary open or laparoscopic vertical banded gastroplasty (OVBG or LVBG, respectively). METHODS: The records of patients who underwent LRYGB as a conversional procedure after VBG between November 2004 and December 2017 were reviewed. Characteristics, body mass index (BMI), operation time, intraoperative problems, length of hospitalization, and early (< 30 days) morbidity and mortality were analyzed. Data were expressed as mean ± standard deviation or frequency. RESULTS: A total of 329 patients (81.76% females) who underwent conversional RYGB were included. For the LVBG group (224 patients) and OVBG group (105 patients), respectively, BMI was 34.15 ± 6.38 and 37.79 ± 6.31 kg/m2 (p < 0.05), the operation time was 96.00 ± 31.40 and 123.15 ± 40.26 min (p < 0.05), hospitalization duration was 2.96 ± 1.13 and 3.20 ± 1.20 days (p = 0.08), the early complication rate was 7.14 and 11.43% (p = 0.19), and the reoperation rate was 2.23 and 2.86% (p = 0.73). There were no major intraoperative problems. Three patients with OVBG were converted to open RYGB (2.86%). There was no mortality. CONCLUSION: The conversion of OVBG and LVBG to laparoscopic RYGB is technically feasible and provides comparably low early morbidity rates and length of hospitalization. However, compared to LVBG, conversional laparoscopic RYGB following OVBG is technically more challenging and time-consuming, with a slightly higher risk of conversion to open surgery. We support the use of such conversional bariatric surgery in specialized, high-volume bariatric centers.

Twelve-Year Experience with Roux-en-Y Gastric Bypass as a Conversional Procedure for Vertical Banded Gastroplasty: Are We on the Right Track?

BACKGROUND: Vertical banded gastroplasty (VBG) has high rates of long-term complications. Conversion to Roux-en-Y gastric bypass (RYGB) is considered optimal; however, there are limited data on the late results of these conversions. We aimed to analyze our single-center long-term outcomes of patients requiring conversional RYGB for a failed VBG. METHODS: The records of patients who underwent RYGB as a conversional procedure after VBG from November 2004 to December 2016 were reviewed. Follow-up data were obtained by direct telephone calls with patients, electronic files, and general practitioner reports. Characteristics, indications of conversion, long-term (> 30 days) morbidities, weight records, obesity-related comorbidities, and overall patient satisfaction were analyzed. RESULTS: Overall, 305 VBG patients (82% female) underwent conversional RYGB during the study period. The mean pre-RYGB body mass index (BMI) was 35.6 (23-66) kg/m2. Conversions were indicated in 61% of patients because of simultaneous VBG complications and weight regain. After a median follow-up of 74.3 (5-151) months, 225 (73.8%) patients agreed to participate. The mean BMI and percentage of total weight loss (%TWL) were 28.6 (18-45) kg/m2 and 17.4%, respectively. Nearly all conversion indications were addressed effectively. Surgical reintervention was mandatory in 28 of 225 patients (12.4%) due to complications. Approximately 85% of patients reported complete remission of obesity-related comorbidities, and four-fifths were fully satisfied. CONCLUSION: RYGB resolves VBG complications, improves quality of life, and results in prolonged stable weight loss. It has a key role in the management of obesity-related comorbidities and in expert hands is the preferred conversional procedure for patients with failed VBG.
