Enhanced recovery after bariatric surgery: an Italian consensus statement.

BACKGROUND: Enhanced recovery after bariatric surgery (ERABS) is an approach developed to improve outcomes in obese surgical patients. Unfortunately, it is not evenly implemented in Italy. The Italian Society for the Surgery of Obesity and Metabolic Diseases and the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care joined in drafting an official statement on ERABS. METHODS: To assess the effectiveness and safety of ERABS and to develop evidence-based recommendations with regard to pre-, intra-, and post-operative care for obese patients undergoing ERABS, a 13-member expert task force of surgeons and anesthesiologists from Italian certified IFSO center of excellence in bariatric surgery was established and a review of English-language papers conducted. Oxford 2011 Levels of Evidence and U.S. Preventive Services Task Force Grade Definitions were used to grade the level of evidence and the strength of recommendations, respectively. The supporting evidence and recommendations were reviewed and discussed by the entire group at meetings to achieve a final consensus. RESULTS: Compared to the conventional approach, ERABS reduces the length of hospital stay and does not heighten the risk of major post-operative complications, re-operations, and hospital re-admissions, nor does it increase the overall surgical costs. A total of 25 recommendations were proposed, covering pre-operative evaluation and care (7 items), intra-operative management (1 item, 11 sub-items), and post-operative care and discharge (6 items). CONCLUSIONS: ERABS is an effective and safe approach. The recommendations allow the proper management of obese patients undergoing ERABS for a better outcome.

Duodenal Obstruction in a Patient Previously Treated With EndoVascular Aneurysm Sealing System Repair.

The Nellix® endovascular aneurysm sealing system (EVAS) is a relatively novel approach for the treatment of abdominal aortic aneurysms (AAAs). We present herein a case of duodenal obstruction (DO) which occurred following an EVAS treatment for the repair of an AAA. A 77-year old man was admitted to our hospital with acute abdominal pain and recurrent vomiting. Computed tomography (CT) revealed a retroperitoneal 66 × 59 × 90 mm (antero-posterior, AP; latero-lateral, LL; cranio-caudal: CC) solid mass located in the epigastrium, corresponding to the infrarenal abdominal aortic aneurysm sac, previously treated by EVAS. An exploratory laparotomy was performed, which revealed a retroperitoneal mass compressing the third and fourth parts of the duodenum. A gastroenteroanastomosis was performed in order to bypass the duodenal obstruction. An extensive search of biomedical literature databases was conducted to identify similar cases. To our knowledge, this is the first reported case of DO following an AAA repair with EVAS.

Totally Laparoscopic Transgastric Resection of a Gastric Submucosal Fibrolipoma and Concomitant Sleeve Gastrectomy in a Morbidly Obese Patient.

INTRODUCTION: To evaluate feasibility and safety of a totally laparoscopic transgastric resection with concomitant sleeve gastrectomy in a morbidly obese presenting with benign lesion located along the lesser gastric curvature. MATERIALS AND METHODS: We report the case of a morbidly obese patient with an incidental submucosal lesion of the lesser curvature radiologically consistent with fibrolipoma at preoperative work-up. Benign nature of the mass was then confirmed EUS-biopsy. RESULTS: A combinated laparoscopic transgastric approach was successfully attempted resulting in a complete excision of the submucosal lesion and concomitant sleeve gastrectomy. Intraoperative and definitive histology confirmed the benign nature of the mass. Postoperative course was uneventful. CONCLUSION: Concomitant transgastric resection of submucosal benign lesions during laparoscopic sleeve gastrectomy represents both a safe and feasible surgical approach in morbidly obese patients. Preoperative work-up is of great importance in order to assess the benign nature of the lesion.

Enhanced Recovery after Bariatric Surgery: 202 Consecutive Patients in an Italian Bariatric Center.

BACKGROUND: Enhanced Recovery After Surgery (ERAS) pathways have been shown to improve postoperative outcomes. However, its application in bariatric surgery is still limited. The aim of the study was to define the safety of ERAS in bariatric patients with regard to postoperative complications, length of hospital stay (LOS), and readmission rates within 30 days from surgery. METHODS: The effectiveness and safety of an ERAS protocol was prospectively investigated in morbidly obese patients who underwent bariatric surgery in a single-institute experience over a 2-year period. RESULTS: Between June 2016 and September 2018, a total of 89 laparoscopic sleeve gastrectomy (SG), 105 Roux-en-Y gastric bypass (RYGB), and 8 one-anastomosis gastric bypass (OAGB) were performed. Twenty patients (9.9%) were revisional cases. Mean (standard deviation, SD) BMI and age at time of surgery were 43.2 (± 6.2) kg/m2 and 46 (± 11.3) years, respectively. Median (range) surgical time was 118 (45-255) minutes. Overall postoperative complication rate was 7.4%, with 6 (3.0%) patients developing grade III-IV complications according to the Clavien-Dindo classification. Median (range) LOS was 2 (1-50) days, with mean (SD) LOS of 2.3 (± 3.6) days. Overall, 36.6% of patients were discharged by first postoperative day and 77.7% by second postoperative day. Readmission rate was 4.5%. No mortality was observed during the study period. CONCLUSIONS: According to the results of the present study, ERAS in primary and revisional bariatric surgery is safe and feasible, with short LOS, low morbidity and readmission rates, and no mortality. A significant reduction of mean LOS was progressively noted over the study period.

Surgical treatment of gastric GIST with acute bleeding using laparoscopic sleeve gastrectomy: A report of two cases.

In this report, we want to emphasize how a laparoscopic bariatric surgical procedure, in experienced hands, has shown to be a valid alternative for the hemorrhage control and the removal of a gastrointestinal tumor in a life-threatening situation.

Emergency laparoscopic conversion from mini/one anastomosis gastric bypass to modified Roux-en-Y-gastric bypass due to acute bleeding from a recurrent marginal ulcer.

Our aim is to present the laparoscopic technique of an emergency revisional procedure performed to convert a mini/one anastomosis gastric bypass (MGB/OAGB) to a modified Roux-en-Y-gastric-bypass (RYGB) due to recurrent bleeding from a marginal ulcer. A 43 year old woman presented unstable conditions due to acute bleeding from a marginal ulcer after a MGB/OAGB performed 3 years before. After three failed endoscopic haemostasis attempts, she underwent a laparoscopic conversion to a modified RYGB in emergency setting. The patient had an uneventful recovery. She maintained heamodynamical stability after the procedure. She was eventually discharged in the seventh postoperative day after restarting oral feeding on chronic proton pump inhibitors. To our knowledge, there are few descriptions of emergency surgical conversion from a MGB/OAGB to a modified laparoscopic RYGB due to a recurrent marginal ulcer bleeding not responsive to endoscopic treatment. A regular post-operative follow-up is mandatory after bariatric surgery. We advocate performing revisional surgery in an experienced Bariatric Center.

Combined endoscopic-laparoscopic T-tube insertion for the treatment of staple-line leak after sleeve gastrectomy: a simple and effective therapeutic option.

BACKGROUND: Management of staple-line leak after laparoscopic sleeve gastrectomy (LSG) remains controversial and matter of debate. Transforming a leak into a controlled fistula by insertion of a T-tube is a viable option. To minimize surgical dissection, and to facilitate identification of the leak site and insertion of the T-tube, we have developed a combined endoscopic-laparoscopic T-tube (ELT-t) insertion technique. METHODS: Between February 2011 and June 2014, 7 patients presented with staple-line leak and were treated with ELT-t insertion. After laparoscopic dissection of the abscess cavity, a guidewire is passed endoscopically through the leak; a polypectomy snare is anchored to the guidewire and retrieved through the patient mouth. The long arm of a T-tube is eventually secured to the snare and pulled down through the leak. RESULTS: All patients were started on oral feeding with the T-tube in place. Serial water-soluble contrast swallows were performed to check for healing, and the T-tube was clamped as soon as no extravasation of contrast was demonstrated. The tube was removed either during the index admission or in the outpatient clinic. The residual fistula closed successfully after T-tube removal in all but one case with a "spiral-shaped" sleeve and functional distal obstruction. This patient was treated with stent. Patients were discharged home after a mean postoperative hospital stay of 53.3 days (range: 15-87 days). CONCLUSION: In our experience, ELT-t is a valid alternative for the treatment of staple-line leak after LSG. It allows minimizing surgical dissection, and appears to be safe and effective.

Safety of Veress needle insertion in laparoscopic bariatric surgery.

BACKGROUND: Creating the pneumoperitoneum is the first surgical procedure in laparoscopic abdominal surgery. Morbid obesity is a risk factor for iatrogenic injuries because of the considerable thickness of the abdominal wall. The aim of this study was to assess the feasibility and the incidence of complications when using Veress needles (VN) in obese patients undergoing bariatric surgery. METHODS: Between March 2004 and December 2010, a retrospective analysis was performed on 139 obese patients (mean body mass index=45.94 kg/m). Blind VN insertion followed by optical trocar insertion was the most widely used technique. RESULTS: Of the 139 patients, VN was successfully used in 138 cases (99.28%), and in 1 patient the procedure failed and an open laparoscopy was performed (0.72%). During the study period, there were 63 gastric bypasses, 18 sleeve gastrectomies, 50 gastric bandings, and 8 reoperations. The VN was inserted in the left upper quadrant in 46 cases and in the midline above the umbilicus in 93 cases. A colonic perforation after VN insertion at the left upper quadrant occurred. The overall rate of complications was 0.72%. There were no access-related complications when VN was inserted above the umbilicus; complication rate was 2.17% at upper left quadrant VN placement. No cases of subcutaneous emphysema or extraperitoneal insufflation were observed. CONCLUSIONS: In our experience, the success rate was 98.28% and the overall rate of complications was 0.72%. The VN technique can be considered feasible and safe even when used in obese population.

Gastric bypass does not normalize obesity-related changes in ghrelin profile and leads to higher acylated ghrelin fraction.

OBJECTIVE: Gastric bypass (GBP) lowers food intake, body weight, and insulin resistance in severe obesity (SO). Ghrelin is a gastric orexigenic and adipogenic hormone contributing to modulate energy balance and insulin action. Total plasma ghrelin (T-Ghr) level is low and inversely related to body weight and insulin resistance in moderately obese patients, but these observations may not extend to the orexigenic acylated form (A-Ghr) whose plasma concentration increase in moderate obesity. DESIGN AND METHODS: We investigated the impact of GBP on plasma T-, A-, and A/T-Ghr in SO patients (n = 28, 20 women), with measurements at baseline and 1, 3, 6, and 12 months after surgery. Additional cross-sectional comparison was performed between nonobese, moderately obese, and SO individuals before GBP and at the end of the follow-up period. RESULTS: Before GBP, SO had lowest T-Ghr and highest A/T-Ghr profile compared with both nonobese and moderately obese individuals. Lack of early (0-3 months from GBP) T-Ghr changes masked a sharp increase in A-Ghr and A/T-Ghr profile (P < 0.05) that remained elevated following later increments (6-12 months) of both T- and A-Ghr (P < 0.05). Levels of A-Ghr and A/T-Ghr at 12 months of follow-up remained higher than in matched moderately obese individuals not treated with surgery (P < 0.05). CONCLUSIONS: The data show that following GBP, early T-Ghr stability masks elevation of A/T-Ghr, that is stabilized after later increments of both T- and A-hormones. GBP does not normalize the obesity-associated elevated A/T-Ghr ratio, instead resulting in enhanced A-Ghr excess. Excess A-Ghr is unlikely to contribute to, and might limit, the common GBP-induced declines of appetite, body weight, and insulin resistance.
