The gastroenterology team performed ERCP with sphincterotomy to retrieve stone in common bile duct but failed. Open cholecystectomy with common bile duct exploration was done after few days. T-tube was placed in common bile duct. In the 8th post operative day, tube manipulation was done due to reduced drain output and pain abdomen. We performed T-tube cholangiogram on 12th postoperative day which showed duodenal migration of T tube. The displaced T tube was retrieved using a simple technique.

The objective of this study was to measure various dimensions of the foramen magnum in Computed Tomography (CT) and correlate them with sex. Methods: Descriptive cross-sectional study was done on 120 CT head images in the Department of Radiology and Imaging, from July to October 2019. The shape of the foramen magnum (FM), anteroposterior diameter (APD), transverse diameter (TD), FM area and FM index were calculated. Statistical analysis was done with SPSS 25 and Excel 2016. Discriminant function analysis and binary logistic regression analysis were used for gender verification. RESULTS: The mean values of the APD, TD, area and FM index in males and females were 33.56 ± 4.30 mm, 29.76 ± 4.10 mm, 792.94 ± 191.60 mm2, 85.01 ± 8.67 and 30.01 ± 2.04 mm, 25.33 ± 4.6 mm, 599.63± 128.13 mm2, 83.17 ± 7.78 respectively. All dimens...
