Abstract

BACKGROUND:

Uncut Roux-en-Y gastrojejunostomy (uRYGJ) was developed to prevent slow peristalsis in the Roux limb after Roux-en-Y gastrojejunostomy (RYGJ). This study compared the incidence of Roux stasis syndrome (RSS) and severe gastric food stasis in gastric cancer patients who underwent RYGJ or uRYGJ after laparoscopic curative distal gastrectomy.

METHODS:

Between January 2006 and June 2012, 319 patients underwent RYGJ or uRYGJ. After covariates were adjusted by propensity score matching, 39 patients in the RYGJ group and 65 patients in the uRYGJ group were included in the final analysis. RSS was defined as the presence of symptoms, such as nausea, vomiting, and abdominal fullness, requiring refasting without ileus or obstruction within 30 days post-surgery. Gastric food stasis was measured endoscopically at 1 and 3 years after gastrectomy.

RESULTS:

Operative outcomes and morbidities were similar between the two groups, whereas the incidence of RSS was higher in the RYGJ group than in the uRYGJ group, although the difference was not significant (7.7 vs. 0%; odds ratio (OR) 0.157; 95% confidence interval (CI) 0-1.059, p = 0.111). Comparison of endoscopic findings revealed that severe gastric stasis 1 year after surgery was significantly less frequent in the uRYGJ group (46.2 vs. 13.8%; OR 0.247; 95% CI 0.102-0.599, p = 0.002). The same result was reproduced 3 years after surgery (39.4 vs. 15.5%; OR 0.279; 95% CI 0.088-0.882, p = 0.030).

CONCLUSIONS:

Compared with RYGJ, uRYGJ after laparoscopic distal gastrectomy is a safe and effective procedure for preventing severe postoperative gastric food stasis.
