Abstract
Common bile duct stones are estimated to be present in 10–20% of individuals with symptomatic gallstones. A variety of imaging modalities can be employed to identify the condition while management of confirmed cases of common bile duct stones may involve endoscopic retrograde cholangiopancreatography, surgery and radiological methods of stone extraction. Clinicians are therefore confronted with a number of potentially valid options to treat individuals with suspected common bile duct stones.
Extraction of ductal stones via an endoscopic biliary sphincterotomy or laparoscopic route may be difficult for a variety of reasons. In most situations, size, shape and number of stones are the key determinants of whether extraction will be easy or not. The likelihood of successful extraction can also be reduced in patients who have altered anatomy as result of previous surgery.
In this study, the data of thirty patients with common bile duct stones who presented for the first time to the department of General surgery at Ain Shams University hospitals, Cairo, Egypt. Were collected during the period of August 2021 to February 2022.
The diagnosis of common bile duct stones was based on clinical, laboratory and radiological findings. All the cases had elevated serum total bilirubin and direct bilirubin, and all had radiological evidence of common bile duct stones by pelvi-abdominal ultrasound or by magnetic resonance cholangio-pancreatography. Clinical signs varied from patient to another as asymptomatic common bile duct stones are not uncommon.
The following parameters were evaluated: age, sex, current illness, medical history, vital signs, laboratory results (complete blood count, liver function, serum bilirubin). Patients were treated with adequate fluid resuscitation and analgesics and antibiotics.
Patients who had common bile duct stones (either primary or secondary) ranging in size between 10-20 mm were involved in our study in accordance with our previously mentioned inclusion and exclusion criteria.
All patients in our study were referred for endoscopic retrograde cholangiopancreatography and success rate of stone extraction was observed in these patients in order to determine if size of common bile duct stones can affect success of endoscopic retrograde cholangiopancreatography stone extraction.
In the current study, all patients received proper pre-operative assessment and were operated on using same endoscope set and by experienced operators. Also, all patients were observed for post endoscopic retrograde cholangiopancreatography complications.
The current study found that endoscopic retrograde cholangiopancreatography stone extraction in stones ranging from 10-20 mm success rate shows no significant difference in comparison with results that were published in different recent researches studying endoscopic retrograde cholangiopancreatography success rate in different stone sizes.
CONCLUSION
The current study found that success rate of ERCP in CBD stones extraction in stones ranging from 10-20 mm in size is 90%. Also, intra-operative complication rate was 6.7% of cases. So ERCP is effective in CBD stone extraction up to the size of 20 mm in diameter.
RECOMMENDATIONS
ERCP is highly effective in CBDS extraction up to the size of 20 mm, especially with CBDS less than 17 mm in diameter.
