Comparison of two methods of creating gastric pouch in laparoscopic gastric bypass in bariatrics / 中华普通外科杂志

ABSTRACT

Objective To compare the difficult degree,differences in gastric pouch volume,the complications,and postoperative weight loss effect of two gastric pouch practices in laparoscopic gastric bypass for bariatrics.Methods We retrospectively analyzed laparoscopic gastric bypass surgery in 76 bariatrics cases from May 2010 to May 2012.Two methods were used to create gastric pouch,among which 39 cases were operated with the dissection landmark method (called dissection),and 37 cases with bougie airbags 30 ml (called the bougie).Parameters were compared between the 2 groups including operation time for gastric pouch,the amount of staple cartridges,intraoperative complications,blood loss,and postoperative excess weight loss percentage (EWL ％),the postoperative bleeding,obstruction,fistula and other complications.Results All patients were followed up for more than one month.The dissection group used longer time in creating gastric pouch than that in the bougie group [(58 ± 27) min,(42 ±21) min,P ＜ 0.01].The number of staple cartridges used were significantly different between the two groups [(6.2 ±3.0),(4.3 ± 2.0),P ＜ 0.01].There were 10 cases of complications in the dissection group (26％),and 3 cases in the bougie group (8％) (P ＜0.05).One month after the surgery,one each patient had transient hematochezia.There was no gastric pouch-related complications in the two groups postoperation.There was no difference in excess weight loss (P ＞ 0.05).Conclusions The two methods can achieve the same effect on excess weight loss.The bougie method used less time in creating the gastric pouch,less consumable materials,and less complications occurred in creating gastric pouch.
