Staple-line reinforcement with a thrombin matrix during laparoscopic sleeve gastrectomy for morbid obesity: a case series.
ABSTRACT Laparoscopic sleeve gastrectomy (LSG) represents a valid option for morbidly obese patients, either as a primary or as a staged procedure. Staple-line reinforcement (SLR) is strongly advocated to decrease the chance of bleeding. The aim of this article is to report our experience with a new technique of SLR using a thrombin-gelatin matrix in a series of morbidly obese patients subjected to LSG.
Patients subjected to LSG using a thrombin-gelatin matrix for SLR from April 2010 to April 2011 were included in the study. Each patient's record was registered and prospectively collected for the analysis.
Seventy-four patients were subjected to LSG using a thrombin matrix for SLR. There were 56 female and 18 male subjects with a mean age of 44.8 years (range, 16-64 years). Mean preoperative body mass index was 46.2 kg/m(2) (range, 40-72 kg/m(2)). Mean operative time was 74.4 minutes (range, 58-96 minutes). Mean time for application of the thrombin matrix was 4.8 minutes (range, 3.2-6.6 minutes). Mean postoperative hospital stay was 3.4 days (range, 2-62 days). Mean follow-up was 8.2 months (range, 3-12 months). Mean postoperative body mass index was 36.2 kg/m(2) (range, 30-42 kg/m(2)), and mean percentage excess weight loss was 34.2% (range, 28.4%-42.8%). We observed two major postoperative complications (2.7%): One gastric stump leak (1.3%) and one major bleeding from the trocar site (1.3%), both successfully treated by laparoscopic re-exploration.
LSG with a thrombin matrix for SLR is a safe operation and a valid alternative to other well-established techniques.

ABSTRACT: The main early complications of Laparascopic Sleeve Gastrectomy are bleeding and gastric leakage. Many reinforcement methods are performed in order to reduce these complications. In this prospective, randomized study, we compared four different techniques to evaluate staple line reinforcement in Laparascopic Sleeve Gastrectomy. Between January 2012 and May 2013, 65 patients were prospectively randomized into four groups in which different techniques were used in handling the staple line during Laparascopic Sleeve Gastrectomy. Of the four groups, there wasn't any reinforcement used on 15 patients during LSG (group 1), continuous serosal 3-0 prolene sutures were used on 16 patients for staple line reinforcement (group 2), staple line was supported with v-loc suture in 16 patients (group 3), and 18 patients had Tisseel fibrin sealant applied throughout the staple line (group 4). 40 of 65 patients were females, the mean age was 36.8 years (20-58 years), and the mean BMI was 49.2 (41-60 kg/m²). Characteristics of patients among groups were similar. There wasn't any significant difference found between groups for BMI. Gastric leakage was detected from the staple line in 2 patients of the v-loc group. According to our results, we demonstrated that good results can be obtained without any reinforcement. Reinforcement with propylene suture only prolongs the operation time, and tissue fibrin sealent increases the cost. In conclusion, we should be more careful using v-loc sutures, and further series with larger numbers are needed to test v-loc.International Journal of Clinical and Experimental Medicine 01/2013; 6(10):985-990. · 1.42 Impact Factor

ABSTRACT: Background Laparoscopic Sleeve Gastrectomy (LSG) is an approved primary procedure for morbid obesity, but it is associated with serious complications, such as staple line leaks and bleeding. Objective To assess the effectiveness of Staple Line Reinforcement (SLR) in reducing leaks and bleeding after LSG. Setting Four high volume bariatric centers between October, 2002 and January, 2012. Methods 1,162 patients underwent LSG (305 males; 857 females). The mean age was 43.7 years and the mean Body Mass Index (BMI) was 48 kg/m2. The patients were divided into six groups based on the type of SLR, including a no-SLR control group, with evaluation of leaking and bleeding risk and correlation of patients’ characteristics with complications. Results 189 patients underwent LSG without reinforcement. The SLR method was oversewing in 476 patients, bovine pericardium in 312, synthetic polyester in 76, glycolide/trimethylene copolymer in 63, and thrombin matrix in 46. The overall leak frequency was 2.8%; higher with synthetic polyester (7.8%), 4.8% with no reinforcement, and lower with bovine pericardium strips (0.3%; p<0.01). Postoperative hemorrhage occurred in 35 patients (3%), with a higher frequency being observed without SLR (13.7%; p=0.02). Only diabetes was a risk-factor for a leak (p<0.01). Conclusions SLR with bovine pericardium strips significantly reduced the leak risk. Postoperative bleeding was significantly lower with all SLR-methods, although there was no significant difference among the various techniques. Patients with type II diabetes had a higher risk of staple line leak after LSG. Further randomized, controlled studies are needed to improve our understanding of the efficacy of SLR during LSG.Surgery for Obesity and Related Diseases 01/2013; 10(3).
