We conducted this study to obtain data on sonographically measured diameters of common bile duct among Rajasthani population in order to determine the range of normal diameters for common bile duct among this population and to determine its association with age, sex, physical measurements like height, weight, chest circumference, circumference at the transpyloric plane, circumference at the umbilicus and circumference at the hip.

This study was conducted among 200 normal subjects belonging to the state of Rajasthan. An equal number of males and females in the age group 18-85 years of age were included in the study. The subjects underwent ultrasonographic measurements of common bile duct diameters by experienced radiologist at the Mahatma Gandhi Medical College and Hospital at Jaipur, India. In addition, anthropometric data on weight, height, chest circumference, circumference at transpyloric plane, circumference at umbilicus and circumference at hip were obtained for each of the study subjects.

Abstract

Aim: Study was conducted to obtain data on sonographically measured diameters of common bile duct in a series of normal Rajasthani population and to measure its correlation with age, sex and anthropometry.

[Table/Fig-2]:

The mean weight and height of the participants was 51.4 kg (SD 12.25 kg) and 163.4 cm (SD 9.98 cm) respectively. The mean circumference measured at levels of chest, transpyloric plane, umbilicus and hip were 83.5 cm (SD 9.04 cm), 75.2 cm (SD 9.94 cm), 78.1 cm (SD 12.02 cm) and 87.2 cm (SD 10.0 cm) respectively.

This report suggests that our novel technique, known as V-CBD, may represent a feasible and straightforward procedure for treating choledocholithiasis, especially when the CBD is not dilated.

All medical data were prospectively collected, including the following: demographic and clinical features (age, sex, American Society of Anesthesiologists (ASA) grade, body mass index (BMI) and preoperative laboratory results); disease characteristics (size and number of stones, diameter of the CBD and the presence of gallstone pancreatitis); and surgical outcomes (CBD clearance, operative time, conversion to laparotomy, length of postoperative hospital stay, postoperative morbidity and mortality). This study was approved by the ethics committee at our institution (Institutional Review Board of Seoul St. Mary’s hospital, College of Medicine, the Catholic University of Korea, IRB code: KC14RISI0814) and all the patients provided their informed consent for the publication of this study.

Conclusions

Laparoscopic common bile duct exploration (LCBDE) is a treatment modality for choledocholithiasis. The advantages of this technique are that it is less invasive than conventional open surgery and it permits single-stage management; however, other technical difficulties limit its use. The aim of this article is to introduce our novel technique for LCBDE, which may overcome some of the limitations of conventional LCBDE.

Since December 2013, ten patients have undergone LCBDE using a V-shaped choledochotomy (V-CBD). After the confluence of the cystic duct and the CBD were exposed, a V-shaped incision was made along the medial wall of the cystic duct and the lateral wall of the common hepatic duct, which comprise two sides of Calot’s triangle. The choledochoscope was inserted into the lumen of the CBD through a V-shaped incision, and all CBD stones were retrieved using a basket or a Fogarty balloon catheter or were irrigated with saline. After CBD clearance was confirmed using the choledochoscope, the choledochotomy was closed with the bard absorbable suture material known as V-loc.

Methods

The aim of this article is to describe our novel technique for LCBDE, which we have termed ‘laparoscopic CBD exploration through a V-shaped choledochotomy (V-CBD).’ This novel approach may help to overcome the limitations of conventional LCBDE for the surgical treatment of choledocholithiasis.
