Endoscopic ultrasonography-guided hepaticogastrostomy as a bridge to the definitive biliary reconstruction in a pediatric patient with left hepatic duct disruption secondary to blunt liver trauma

INTRODUCTION: Jaundice means yellow due to the yellowish discolouration of skin, sclera, and mucous membrane seen in jaundice caused by bilirubin pigment. It is divided in to two forms obstructive(surgical) and non- obstructive (non-surgical). AIM AND OBJECTIVE: To evaluate patients of obstructive jaundice by sonography and magnetic resonance cholangiopancreatography and compare the reporting and ndings by both the modalities. MATERIALS AND METHODS: Cross sectional observational study done from November 2018 to October 2020 and consists of 32 patients who had clinical jaundice and consented to being subjected to both ultrasound and MRCP. OBSERVATIONS:Both USG and MRCP were able to detect extrahepatic CBD dilatation equally in 25 patients. In 5(15.6%) patients USG and MRI both demonstrated intrahepatic mass causing obstruction at the level of conuence of right and left hepatic duct or CHD. Ultrasonography was able to detect the intrinsic mass of the extrahepatic common bile duct in 2(6.2%) patients out of 32 patients in our study population. MRCP could detect the same in 6(18.7%) patients. In our study narrowing of CBD with stricture formation and upstream dilatation of biliary tree was identied in 10(31.2%) patients on MRCP. Ultrasound could diagnose the same in one patient. Both USG and MRCP were able to detect pancreatic head mass as well as pseudocyst. CONCLUSION: The accuracy of MRCP was found to be comparable to that of ERCP for diagnosis of etiology for obstructive jaundice. MRCP allows better lesion characterization and assessment. However, the patchy availability of MR machines become the main achilles heel for the surgeons as well as the radiologists. Hence the valuable role of the omnipresent ultrasonography become immense.

Purpose. Thorough understanding of biliary anatomy is required when performing surgical interventions in the hepatobiliary system. This study describes the anatomical variations of right bile ducts in terms of branching and drainage patterns, and determines their frequency. Methods. We studied 73 samples of cadaveric material, focusing on the relationship of the right anterior and posterior segmental branches, the way they form the right hepatic duct, and the main variations of their drainage pattern. Results. The anatomy of the right hepatic duct was typical in 65.75% of samples. Ectopic drainage of the right anterior duct into the common hepatic duct was found in 15.07% and triple confluence in 9.59%. Ectopic drainage of the right posterior duct into the common hepatic duct was discovered in 2.74% and ectopic drainage of the right posterior duct into the left hepatic duct in 4.11%. Ectopic drainage of the right anterior duct into the left hepatic ductal system and ectopic drainage of the right posterior duct into the cystic duct was found in 1.37%. Conclusion. The branching pattern of the right hepatic duct was atypical in 34.25% of cases. Thus, knowledge of the anatomical variations of the extrahepatic bile ducts is important in many surgical cases.

Key Steps

Introduction: The laparoscopic approach in liver surgery has been preferred over the traditional approach in the resection of segments 2 and 3, as laparoscopic surgical technique can be standardized for easy adoption and is minimally invasive. This paper describes the laparoscopic surgical technique and recommends the patient selection criteria in the resection of segments 2, 3 and 4. Methods: This technique involves 2 key steps – early division of the left pedicle before the division of the liver parenchyma and the placement of an instrument beneath the transection plane to simulate a ‘hanging manoeuvre’ with reduced blood loss and allows the expeditious division of the liver parenchyma. Apart from the usual contraindications to liver resections, specific contraindications to this technique include patients with aberrant biliary drainage of right liver segments into the left hepatic duct, patients with tumours abutting the hilar plate and patients with tumours located near the junction of the left hepatic vein and the vena cava. Conclusion: The authors recommend these steps to serve as a standardized technique for laparoscopic hepatectomy of segments 2,3 and 4 in selected patients, allowing the learning curve for this technique to be markedly shortened
