The laparoscopic Roux Y gastric bypass (LRYGB) is one of the most often performed bariatric surgical intervention. Intraoperative gastroscopy (IOG) seems to be reliable to decrease the leakage rate of gastrojejunal anastomosis (GJA) and of gastric pouch (GP). Our aim was to test the efficacy and the safety of this method. Two hundred fifty-two LRYGB operations were performed in our institution between 1 January 2008 and 1 January 2010. IOG is routinely made to test the integrity of GJA and of GP. Patients' dates were retrospectively analysed. The intragastric pressure developed during gastroscopy in humans was measured and compared with pressure values led to destruction (positive air test) of the GJA and/or GP in animal models (hybrid pigs). Stomach and bowel wall samples from the test animals without pressure strain, with pressure strain developed at gastroscopy in humans and with pressure strains led to destruction of GJA and/or GP were histologically examined. IOG resulted in six of our cases (2.3%) positive air test. There was no anastomosis insufficiency in postoperative period. Mean pressure during IOG was 32 mmHg, mean time of examination was 3.8 min and mean maximal pressure was 43 mmHg in humans. The mean pressure leading to positive air test in pigs was 150 mmHg. We could not detect any microscopical difference between stomach and jejunum samples without pressure strain and after pressure strain developed in humans during the gastroscopy. We conclude that intraoperative gastroscopy is an effective and safe method to test the integrity of GJA and GP in LRYGB surgery. |
