Purpose
We used propensity score matching to compare the complication rates after laparoscopic total gastrectomy (LTG) with esophagojejunostomy (EJS) performed using a circular or a linear stapler.
Methods
We retrospectively enrolled all patients who underwent curative LTG between November 2004 and March 2016. Patients were categorized into the circular and linear groups according to the stapler type used for the subsequent EJS. Patients in the groups were matched using the following propensity score covariates: age, sex, body mass index, American Society of Anesthesiologists physical status, extent of lymph node dissection, and Japanese Classification of Gastric Carcinoma stage. Clinicopathological characteristics and surgical outcomes were compared.
Results
We identified 66 propensity score-matched pairs among 379 patients who underwent LTG. There was no significant between-group difference in the median operative time, extent of lymph node dissection, number of lymph nodes resected, rate of conversion to open surgery, or number of surgeries performed by a surgeon certified by the Japanese Society of Endoscopic Surgery. In the circular and linear groups, the rate of all complications (Clavien–Dindo [CD] classification ≥ I; 21 vs. 26%, respectively; p = 0.538), complications more severe than CD grade III (14 vs. 14%, respectively; p = 1.000), and occurrence of EJS leakage and stenosis more severe than CD grade III (5 vs. 2%, p = 0.301; 9 vs. 8%, p = 0.753, respectively) were comparable.
Conclusions
There is no difference in the postoperative complication rate related to the type of stapler used for EJS after LTG.
