Objective:
To evaluate the short-term outcomes of mechanical and hand-sewn laparoscopic one-anastomosis mini-gastric bypass.
Material And Methods:
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).
Results:
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.
Conclusion:
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.
