| 摘 要： | AIM:To report the results of a medical management of sphincter of oddi dysfunction(SOD) after an intermediate follow-up period.METHODS:A total of 59 patients with SOD(2 men and 57 women,mean age 51 years old) were included in this prospective study.After medical treatment for one year,the patients were clinically re-evaluated after an average period of 30 mo.RESULTS:The distribution of the patients according to the Milwaukee's classification was the following:11 patients were type 1,34 were type 2 and 14 were type 3.Fourteen patients underwent an endoscopic sphincterotomy(ES) after one year of medical treatment.The median intermediate follow-up period was 29.8 ± 3 mo(3-72 mo).The initial effectiveness of the medical treatment was complete,partial and poor among 50.8%,13.5% and 35%,respectively,of the patients.At the end of the follow-up period,37 patients(62.7%) showed more than 50% improvement.The rate of improvement in patients who required ES was not significantly different compared with the patients treated conservatively(64.2% vs 62.2%,respectively).CONCLUSION:Our study confirms that conservative medical treatment could be an alternative to endoscopic sphincterotomy because,after an intermediate follow-up period,the two treatments show the same success rates.
