Purpose
Laparoscopic pylorus-preserving gastrectomy (LPPG) is performed to preserve function in treating early gastric cancer. However, gastric stasis is a potential complication of LPPG that could decrease postoperative quality of life, possibly due to gastric edema of the pyloric cuff caused by venous stasis. We introduced an infrapyloric vein (IPV)-preserving LPPG (iLPPG) procedure to prevent pyloric cuff edema and thus minimize the incidence of gastric stasis and investigated the early clinical outcomes of iLPPG.
Methods
We reviewed 150 patients with gastric cancer who underwent LPPG between August 2011 and June 2013 at the Cancer Institute Hospital and analyzed postoperative complications, incidence of gastric stasis (requiring starvation longer than 72 h or an invasive treatment), and transient delayed gastric emptying (TDGE).
Results
Of the 150 patients, 56 underwent iLPPG and 94 underwent conventional LPPG without preservation of the IPV (cLPPG). Morbidity rates were 5.4% in the iLPPG group and 23.4% in the cLPPG group (P = 0.003). The incidence of both gastric stasis and TDGE was significantly lower in the iLPPG group than in the cLPPG group (0 vs. 8.5%, P = 0.03 and 0 vs. 7.4%, P = 0.046, respectively). Median postoperative stay was significantly shorter in the iLPPG group compared to the cLPPG group (9 vs. 11 days, P < 0.001, respectively).
Conclusions
Preservation of the IPV might prevent the incidence of postoperative gastric stasis after LPPG, resulting in a shorter postoperative stay.
