Exploration of the common bile duct via transduodenal sphincteroplasty is thorough and provides an opportunity for the natural passage of retained calculi. However, this procedure destroys both the sphincter ampulla and sphincter choledochus, the sequelae of which are unknown. Fifty patients who had a transduodenal sphincteroplasty performed between 1970 and 1980 were randomly selected and compared with 50 patients who only had cholecystectomy. They were all seen in the outpatient department, assessed on a modified Visick scale and had liver function tests performed. There was no statistical difference in the subjective quality of result or in the liver function of the sphincteroplasty group when compared with the cholecystectomy patients, which suggests that destruction of the sphincters does not appear to be harmful to the patient.
经十二指肠括约肌成形术对胆总管的探查较为彻底，为残留结石的自然排出提供了机会。然而，该手术会破坏壶腹括约肌和胆总管括约肌，其后果尚不清楚。随机选取了1970年至1980年间接受经十二指肠括约肌成形术的50例患者，并与50例仅接受胆囊切除术的患者进行比较。他们均在门诊就诊，采用改良的Visick量表进行评估，并进行了肝功能检查。与胆囊切除术患者相比，括约肌成形术组在主观结果质量或肝功能方面均无统计学差异，这表明括约肌的破坏似乎对患者无害。
