Evaluation of morphometry in extrahepatic bile ducts in preoperative and postoperative periods in diabetic and non-diabetic patients with cholelithiasis

Evaluation of Morphometry in Extrahepatic Bile Ducts in Preoperative and Postoperative Periods in Diabetic and Non-Diabetic Patients With Cholelithiasis Aim: The aim of this study was to find out the effect of cholecystectomy performed due to gallstone on the extrahepatic bile ducts morphometry in diabetic and non-diabetic patients. Material and Method: Three groups consisting of a total of 120 individuals, 60 women and 60 men, between the ages of 17 and 85 were designed. DC group consisted of 40 diabetic individuals with cholelithiasis, N-DC group consisted of 40 individuals with only cholelithiasis and H group consisted of 40 healthy individuals (control group). Laparoscopic cholecystectomy was performed on individuals with cholelithiasis. DHC diameter was measured below hepatic canal bifurcation from mucosa to mucosa by ultrasonography. In addition, vena portae diameters were also measured. The measurements were conducted in preoperative period and in the third and sixth postoperative months. All the measurements were made by the same experienced radiologist by using the same ultrasonography device. Results: A weak positive correlation was found in all groups (DC, N-DC and H) between DHC diameter and age. There were no significant differences between DC and N-DC groups in terms of DHC diameters in preoperative period and postoperative third and sixth months. In both DC and N-DC groups, DHC diameter in postoperative third and sixth months were found to show a small but statistically significant increase. Conclusion: This study showed a small but statistically significant dilatation in DHC following cholecystectomy. In addition, no statistically significant difference was found between DC and N-DC groups in terms of post- cholecystectomy DHC dilatation.
