Short-term outcomes of mechanical and hand-sewn laparoscopic one-anastomosis mini-gastric bypass

Abstract

To evaluate the short-term outcomes of mechanical and hand-sewn laparoscopic one-anastomosis mini-gastric bypass. There were 233 patients who underwent laparoscopic one-anastomosis mini-gastric bypass. Short-term results were analyzed in groups of mechanical (the first group, n=108) and hand-sewn (the second group, n=125) gastrojejunostomy. No significant between-group differences in baseline data were detected (demographic characteristics, body mass index, comorbidity and previous abdominal surgeries). Surgery time and blood loss were similar in both groups. Intraoperative morbidity was 7.2-10.2% (p=0.485). All complications required no surgical conversion (Satava-Kazaryan grade I). Overall postoperative morbidity was 16.0-21.3% (p=0.314). Most events corresponded to Accordion grade I and had no significant effect on hospital-stay. This study revealed no significant differences in short-term outcomes after laparoscopic one-anastomosis gastric bypass with mechanical and hand-sewn gastrojejunostomy. Further study of long-term clinical outcomes is necessary.
