[Comparison of the minimally invasive treatments of laparoscopic and endosopic for common bile duct stones after gastrojejunostomy].

OBJECTIVE: To explore the feasibility and to compare the merits and demerits of laparoscopic and endoscopic approach in removing common bile duct stones in patients with gastrojejunostomy after gastrectomy. METHODS: Between January 2012 and December 2016, 25 patients with common bile duct stones after gastrojejunostomy received laparoscopic or endoscopic treatment in our centers. They were divided into laparoscopic group and endoscopic group based on treatment approaches for common bile duct stones, including 15 patients in laparoscopic group and 10 in endoscopic group. The clinical characteristics and outcomes between the two groups were retrospectively analyzed. RESULTS: Among the 25 patients with gastrojejunostomy, the method of reconstruction was Billroth II in 21 patients and Roux-en-Y in 4 patients. Six patients received laparoscopic or endoscopic treatment during the acute cholangitis state. Among the laparoscopic group, 5 patients with stones more than 1 cm, 7 patients with multiple stones, while in the endoscopic group, 3 patients with stones more than 1 cm and 4 patients with multiple stones. Fourteen patients in the laparoscopic group with coexisting gallbladder stones, and 6 of their common bile duct stones were successfully removed by transcystic approach without T tube drainage. Stone removals were successful in 4 patients of the endoscopic group by a single performance, including 3 patients with single small stone and one patient with multiple small stones. Two patients in the laparoscopic group were converted to open surgery for severe adhesion and one patient in the endoscopic group turned to laparoscopic operation for failing of finding papilla in the Roux-en-Y anastomotic status. The median hospital stays were 12 d and 10 d, respectively in the laparoscopic and endoscopic group. There were 3 patients with postoperative complications, including one patient with paralytic ileus in the laparoscopic group and 2 patients with biliary pancreatitis or bacteremia in the endoscopic group, and all of them recovered uneventfully with conservative treatment. CONCLUSION: Both laparoscopic and endoscopic approaches are feasible for removing stones in the common bile duct in patients with gastrojejunostomy after gastrectomy, and they complement each other. In addition, both techniques are difficult to conduct, and a technical competence should be considered in selection of each method.
