Abstract

PURPOSE
To report our initial experience with laparoscopic mini-gastric bypass (LMGB) in Korean obese patients.
MATERIALS AND METHODS
From July 2016 to February 2018, 14 male patients underwent LMGB for morbid obesity at a single institution. Five trocars were placed in a U-shape formation and 1 trocar was placed at the epigastrium as a liver retractor; a window was created between the vagal nerve and lesser curvature at the gastric angle for entering the lesser sac; a narrow gastric tube (~100-120 ml volume) was made; a linear-stapled gastrojejunostomy was created after bypassing the jejunum 200 cm from the Treitz' ligament; and the Petersen defect was closed to prevent internal hernia. Patient demographics, operative time, estimated blood loss, postoperative hospital stay, complications, weight loss, and resolution of comorbidities were evaluated during 1 year of follow-up.
RESULTS
All procedures were successful by laparoscopy. The average age was 29 (19-49) years; weight, 164.9 (127-250) kg; and body mass index, 51.0 (42.4-81.6) kg/m². In 1 case, nephrectomy was simultaneously performed for early renal cell carcinoma. The mean operative time was 148.8 (120-175) min. The mean postoperative hospital stay was 1.9 (1-4) days. The percentage excess weight loss at 1, 3, 6, 9, and 12 months was 16.6%, 31.0%, 41.4%, 45.4%, and 50.4%, respectively. The resolution rate of type 2 diabetes mellitus, hypertension, and dyslipidemia was 75%, 40%, and 66.7%, respectively. There was no major complication including mortality during the follow-up.
CONCLUSION
LMGB is a technically simple, safe, and effective procedure in Korean obese patients.
