The Incidence of Gallstones After Gastrectomy

A large number of clinical studies have found that the incidence of gallstones in patients after radical gastric cancer surgery is higher than that in the normal population. However, the pathogenesis has not been clarified, and the prophylactic removal of the gallbladder in patients with gastric cancer remains controversial. A previous study found a statistically significant incidence of gallbladder stones after Billroth I versus Roux-en-Y in distal gastrectomy for gastric cancer. Therefore, the investigators plan to conduct a retrospected cohort study to collect further participants with gastric cancer who underwent total gastrectomy to answer whether different surgical resection ranges during surgery increase the incidence of gallstones this question.
