Sphincteroplasty was done via the extraperitoneal transduodenal approach in 42 patients. The indications were residual stones in 34 patients, stricture at Oddi's sphincter in seven patients, and relapsing pancreatitis in one patient. Seven patients suffered operative complications, with one death. Sphincteroplasty was successfully performed in all patients, and the residual stones were removed in 31. Thirty-three of the 36 patients followed up for a mean of seven years were asymptomatic. Extraperitoneal sphincteroplasty has a role in supplementing endoscopic papillotomy and percutaneous extraction through the T-tube tract in the treatment of patients with residual stones.
42例患者通过腹膜外经十二指肠途径进行了括约肌成形术。适应证为34例残留结石、7例Oddi括约肌狭窄和1例复发性胰腺炎。7例患者出现手术并发症，1例死亡。所有患者均成功进行了括约肌成形术，31例患者的残留结石被清除。36例平均随访7年的患者中，33例无症状。腹膜外括约肌成形术在补充内镜乳头切开术和经T管窦道经皮取石治疗残留结石患者方面具有作用。
