Endoscopic sphincterotomy(EST) is a routine therapeutic endoscopic retrograde cholangiopancreatography(ERCP) procedure usually used. It is safe and effective, but severe perforation or massive bleeding are the main causes of mortality. Because of the permanent destroy ofOddi sphincter, the use of EST is still controversial. Endoscopic papillary balloon dilation(EPBD) gives another way to open the sphincter. Less incidence of bleeding, perforation and partly preserving the Oddi sphincter's function are the main advantages. But high incidence of post-ERCP pancreatitis becomes a predominant problem. According to the anatomical feature of Oddi sphincter, limited EST + EPBD seems a more reasonable procedure. Compared to the former two procedures, it makes the stone extraction process much easier with lower incidences of short-term and long-term complications.展开更多

Their demographic, laboratory and procedural data were collected, and pancreaticobiliary complications were recorded.RESULTS Sixty-nine(94.5%) of the patients in the EPLBD + m EST group and 64(84.2%) in the conventional EST group achieved stone clearance following the first session(P = 0.0421). The procedure time for EPLBD + m EST was shorter than for EST alone(42.1 ± 13.6 min vs 47.3 ± 11.8 min, P = 0.0128). The overall rate of early complications in the EPLBD + m EST group(11%) was lower than in the EST group(21.1%); however, the difference was not significant(P = 0.0938). The cumulative recurrence rate of cholangitis and CBD stones between the two groups was also similar. The procedure time was independently associated with post-endoscopic retrograde cholangiopancreatography pancreatitis(OR = 6.374, 95%CI: 1.193-22.624, P = 0.023), CBD stone diameter ≥ 16 mm(OR = 7.463, 95%CI: 2.705-21.246, P = 0.0452) and use of mechanical lithotripsy(OR = 9.913, 95%CI: 3.446-23.154, P = 0.0133) were independent risk factors for stone recurrence. CONCLUSION EPLBD with m EST is more effective than EST alone for difficult CBD stone removal, with shorter procedure time and fewer early complications.展开更多
