Prevention of incisional hernia after single-port sleeve gastrectomy (PRISM): a prospective non-randomized controlled study.

BACKGROUND: SPSG carries a risk of incisional hernia, particularly in patients with high body mass index. Prophylactic mesh placement with either permanent or absorbable mesh could decrease the occurrence of incisional hernia, with uncertainty on other postoperative parietal complications. METHODS: This is a non-randomized monocentric single-blinded prospective study. High-risk patients (body mass index ≥ 45 kg/m2) underwent either 3 strategies of parietal closure (suture with or without permanent or absorbable mesh) during SPSG. The primary outcome was the occurrence of radiologically defined incisional hernia during the first postoperative year. Secondary outcomes included surgical site infection rates and postoperative pain. RESULTS: Between November 2018 and November 2019, 255 patients were included (85 in each group). All patients reached one-year postoperative follow-up. Significantly more incisional hernias were observed in the no mesh group in comparison with permanent and absorbable mesh groups, respectively (20% vs. 7.1% vs. 5.1%, P = 0.005). No difference was observed in mesh groups. No difference was observed regarding other parietal complications. One patient in the absorbable mesh group presented a superficial surgical site infection and required surgical drainage without mesh removal and one patient in the permanent mesh group presented a parietal hematoma and required surgical drainage with mesh removal. Twenty-six (92.8%) asymptomatic patients presented incisional hernia discovered on the one-year CT-scan. CONCLUSIONS: Prophylactic mesh placement during SPSG decreases the occurrence of postoperative incisional hernia. Routine permanent mesh placement could be proposed in high-risk patients.

Single-port Laparoscopic Surgery for the Treatment of Severe Obesity: Review and Perspectives.

This report aims to review current data on single-incision (single-port) laparoscopic surgery (SILS) for bariatric surgery. A comprehensive research of Pubmed database and Cochrane library on SILS bariatric surgery was conducted. Twenty-eight articles met inclusion criteria (3611 patients). Intraoperative and clinical outcomes for SILS sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and adjustable gastric banding (AGB) seem comparable to conventional laparoscopy. SILS for SG was safe and feasible with good outcomes. The same stands for RYGB but more studies are necessary for safe conclusions, while additional trocars are necessary to perform the procedure. AGB is feasible and safe by SILS but the declining number of annual procedures will probably limit the use of SILS. Major studies are unavailable for SILS and other bariatric procedures.

Delayed Intra Splenic Abscess: a Specific Complication Following Laparoscopic Sleeve Gastrectomy.

BACKGROUND: Delayed intra splenic abscess after laparoscopic sleeve gastrectomy (LSG) is a very rare complication with poor manifestations. METHODS: We present three cases of delayed intrasplenic abscess which were managed in our departmentof minimal invasive surgery. DISCUSSION: Splenic abscess may occur in the early post-operative period following LSG; it is usually an extra splenic event after the gastric leak or an infected hematoma. In our cases, two patients had an asymptomatic ischemic demarcation in the upper part of the spleen. This underlines the possible role of ischemia as a factor in abscess formation of late intrasplenic abscesses that enhanced by a state of transient immune suppression. CONCLUSION: Intrasplenic abscess complicating laparoscopic sleeve gastrectomy is different from early extra splenic abscesses. The exact causes are still unclear; the role of partial splenic ischemia has to be rolled out.

Laparoscopic Gastric Plication (LGP) as an Alternative to Laparoscopic Sleeve Gastrectomy (LSG) in Patients with Morbid Obesity: A Preliminary, Short-Term, Case-Control Study.

BACKGROUND: Based on short-term outcome, gastric plication (LGP) could be considered as an alternative to sleeve gastrectomy (LSG) in patients with severe obesity. However, long-term follow-up of weight loss and comorbidity are yet to be available. Theoretical advantages include reduced fistula rate, no implantable device, preservation of the alimentary pathway, and no gastric resection. We report a case-control study comparing short-term outcome in two groups of patients who had either LGP or LSG, respectively. METHODS: From January 2012 to June 2013, 40 patients had LGP, matched with 40 patients who had LSG. RESULTS: No postoperative mortality was observed. Overall morbidity rate reached 22.5 % in the LGP Group and 10 % in the LSG Group (P = 0.04). The most common complication was nausea and vomiting occurring in 20 % of patients with LGP and 5 % of patients with LSG, respectively (P < 0.001). No clinical or radiological leak occurred. Mean operative time was 91.5 ±18.6 min in the LGP group and 81 min ±16.8 min in the LSG group, respectively (P = 0.104). Mean hospital stay was 3.4 ±1.1 days in the LGP Group and 3.2 ±1.2 days the LSG group, respectively (P = 0.614). Average total operating room (OR) cost was 1736 euros for LGP as compared to 2842 euros for LSG, respectively (P < 0.001). At 18-month follow-up, mean excess weight loss (EWL) was 56.5 % +9.8 in LGP patients and 71.3 % +10.4 in patients who had LSG (P = 0.041). CONCLUSIONS: LGP for patients with severe obesity is safe and feasible with low rates of serious complications. As compared to LSG, LGP is associated to higher postoperative rate of nausea, lower operative cost, and lower EWL at 18-month follow-up (P = 0.041).

Roux-En-Y Fistulo-Jejunostomy as a salvage procedure in patients with post-sleeve gastrectomy fistula.

BACKGROUND: Sleeve gastrectomy (SG) is currently the most common bariatric procedure in France. It achieves both adequate excess weight loss and significant reduction of comorbidities. However, leak is still the most common complication after SG. Nevertheless, its risk of occurrence is <3% in specialized centers. Its management is difficult, long, and challenging. Although the procedure is commonly endoscopic and nonoperative, the management of post-SG fistulas could sometimes be surgical, including peritoneal lavage, abscess drainage, disrupted staple line suturing, resleeve, gastric bypass, or total gastrectomy. Roux-en-Y fistulojejunostomy (RYFJ) has been described as a salvage option. In this study, we report the early results of RYFJ for post-SG fistula, emphasizing indications, operative technique, and short-term outcome. METHODS: Between January 2007 and December 2012, we treated 62 patients with post-SG fistula. Before surgery, intra-abdominal or thoracic abscesses or collections were either excluded or treated by computed tomographic scan-guided drainage or even surgery. Endoscopic stenting was then attempted. After optimization of the nutritional status in case of failure of endoscopic measures, some of the patients underwent RYFJ. RESULTS: Between January 2007 and December 2012, a total of 21 patients (16 women and 5 men) had RYFJ for post-SG fistula. Mean age was 47 years (range, 22-59 years). Procedures were performed laparoscopically in all but 3 cases. The rate of secondary conversion to laparotomy was 11.1%. The was no mortality. The postoperative morbidity rate was less than 5%. The rate of fistula control was eventually 100%. CONCLUSIONS: RYFJ is a safe and feasible salvage procedure for the treatment of patients with post-SG fistula. Longer outcome analysis is, however, needed especially regarding the physiological and metabolic behavior of the procedure.
