Preservation of hepatic branch of the vagus nerve reduces the risk of gallstone formation after gastrectomy.

摘要: Injury to the vagus nerve has been proposed be associated with occurrence of gallstones after gastrectomy. We investigated effect preservation hepatic branch on prevention during laparoscopic distal (LDG) and pylorus-preserving gastrectomy (LPPG). Preservation was reviewed cT1N0M0 gastric cancer patients underwent LDG (n = 323) LPPG (n = 144) 2016–2017. Presence evaluated by ultrasonography (US) computed tomography (CT). Incidences were compared between preserved (h-DG, h-PPG) group sacrificed (s-DG, s-PPG) group. Clinicopathological features also compared. The 3-year cumulative incidence lower in h-DG (2.7%, n = 85) than s-DG (14.6%, n = 238) (p = 0.017) h-PPG (1.6%, n = 123) s-PPG (12.9%, n = 21) (p = 0.004). Overall postoperative complication rate similar (p = 0.861) as well (p = 0.768). number retrieved lymph nodes station #1 recurrence-free survival not significantly different (p = 0.001) high body mass index (BMI) (≥ 27.5 kg/m2) (p = 0.040) found independent risk factors gallstone formation multivariate analysis. can recommended for early reduce formation.
