A Randomized, Clinical Trial Involving Different Surgical Methods Affecting the Sphincter of Oddi in Patients With Choledocholithiasis

Abstract

After EST, the SO basal and contraction pressures decreased, and the duodenobiliary reflux and stone recurrence rates increased. Thus, EST should be selected with care.

Laparoscopic Common Bile Duct Exploration Is a Safe and Effective Strategy for Elderly Patients

“…The safety and efficacy of LCBDE has been demonstrated by many medical centers; meanwhile, the function of the papillary sphincter can be restored without damage. 5,6 Complications such as internal hemorrhage, intestinal perforation, acute pancreatitis, and reflux cholangitis have been reported frequently after EST procedures 7-9 ; therefore, the advantage of endoscopic therapy has to be reappraised.…”

Manometric Measurement of the Sphincter of Oddi in Patients with Common Bile Duct Stones: A Consecutive Study of the Han Population of China

“…Our results showed a significantly increased basal SO pressure value of 52.68 ± 40.03 mmHg in the enrolled patients. Yuan et al [17] reported that the basal SO pressure values in two groups of Chinese patients with choledocholithiasis were 30.88 ± 16.11 and 27.80 ± 15.88 mmHg. In a study by Yang et al [18], values of basal SO pressure, amplitude, and frequency were not reported.…”

Comparison of open, laparo-endoscopic and one-stage laparoscopic approaches for treatment of gallbladder and common bile duct stones

“…According to the results, three months after endoscopic sphincterotomy, basal and contraction pressures decreased, and the duodenobiliary reflux and stone recurrence rates increased. [13] The intervention way (transcystic or transcholedocheal) and management of choledochotomy wound (primary suture, T-drainage or stend) are unsolved issues in laparoscopic CBD exploration. In our experience, we implemented transcytic in 35% cases, and transcholedocheal intervention in remaining cases.…”
