What Every Bariatric Surgeon Should Know: How to Relieve Obstruction at the Jejuno-jejunostomy After Roux-en-Y Gastric Bypass.

INTRODUCTION: Roux-en-Y gastric bypass (RYGB) remains one of the key bariatric procedures worldwide. In addition to bleeding and anastomotic leak, there are rarely occurring complications such as obstruction at the jejuno-jejunostomy in the early postoperative phase. PATIENT AND METHODS: A 51-year-old lady (weight 122 kg; BMI 46 kg/m2; with type 2 diabetes mellitus and hypertension) underwent RYGB in our tertiary referral centre 3 days prior to admission. She originally recovered well from the uneventful operation, but began vomiting on day 3. At this point, she complained of no other symptoms. An urgent CT scan identified a gastric remnant dilatation, and an obstructed jejuno-jejunostomy. An urgent laparoscopic exploration was performed, which identified obstruction at this level. RESULTS: Within our video-presentation, detailed technical steps are described. First, gastric remnant decompression was performed by inserting a tube gastrostomy. Secondly, the obstruction was identified. Consequently, a new jejuno-jejunostomy was created, proximal to the original anastomosis, using a linear stapler, and direct suture closure of the enterotomy defects. After thorough washout, drains were placed in the pelvis and alongside the jejuno-jejunostomy. The patient was discharged home after a 2-week hospital stay which included 5 days of invasive ventilation on the ITU. CONCLUSION: A high-level of suspicion is required to suspect, diagnose and treat post-RYGB complications. A bariatric on-call rota with appropriately trained personnel is essential.

Obstructive Sleep Apnoea Screening Preoperatively with the Epworth Questionnaire: Is It Worth It ?

BACKGROUND: The prevalence of obstructive sleep apnoea (OSA) in the bariatric population has been reported to be as high as 60-83%. The Epworth Sleepiness Scale (ESS) is a validated, self-administrated eight-item questionnaire that measures subjective daytime sleepiness and thus helps to identify high-risk for OSA. OBJECTIVES: To find the prevalence of OSA in patients undergoing bariatric surgery who do not routinely undergo polysomnography (PSG) and are screened by the ESS. METHODS: All consecutive 425 patients who underwent bariatric surgery in our tercier referral centre from January 2012 to June 2017 were included in this prospective study. Patient demographics and ESS score were recorded prior to the bariatric surgery and patients were divided into low-risk (ESS < 11), high-risk (≥ 11) and "known-OSA" groups. RESULTS: The community-based OSA prevalence was 14% (59 patients). ESS-positive predictive value was 60%. There was no significant difference in BMI and excess body-weight, but patients with OSA were older and had a lower female ratio (75% vs 42%). The unplanned ICU admission rate was comparable amongst the low- and high-ESS group (2.2% and 2.1%, respectively); similarly, the respiratory and chest complication rate were similar. The median hospital stay for patients diagnosed with OSA was a half day longer; the high-score patients stayed significantly longer than the low-score patients (p = 0.017). CONCLUSION: In our study, the OSA prevalence was low (20%). We think that the ESS does not have significant predicting value before bariatric surgery and overall the OSA is "overhyped" in the bariatric pathway.

Etiology of Leaks Following Sleeve Gastrectomy: Current Evidence.

PURPOSE: The purpose of this paper is to study the causes of leaks following sleeve gastrectomy (SG). MATERIALS AND METHODS: Pubmed was searched during January 2016 for publications reporting leak after SG. A total of 205 publications were identified, of which 17 papers were selected. RESULTS: In about 3018 patients, reinforcement was used compared with 4595 patients, in whom no reinforcement was applied; both groups were representing matched bariatric populations. The use of reinforcement/buttressing has resulted in different rates of leaks ranging from 0% to 3.9%; whereas with no reinforcement/buttressing, the leak rate was 0.16% to 3.5%. The use of reinforcement/buttressing did not result in reduction of leak to a statistical significance although the trend was suggesting so (P=0.06), whereas no reinforcement/buttressing did not statistically increase the leak rate (P=0.10). CONCLUSIONS: No statistical significant difference of leak with or without reinforcement. This mean case complexity and surgical technique and experience are the sole factors for leaks following SG.
