Background: Cystic duct drains the bile from the gallbladder into the common bile duct. Gallstone disease is one of the most common problems affecting the digestive tract and may lead to many complications. To avoid the complications in these patients the gallbladder is removed surgically (Cholecystectomy). Ligation of cystic duct and cystic artery is a prerequisite procedure when cholecystectomy is done. Understanding about the normal anatomy & the possible variations in biliary ductal system is important for the surgeons for doing cholecystectomy surgery successfully. Errors during gallbladder surgery commonly result from failure to appreciate the common variations in the anatomy of the biliary system. Aim of the study: To find out the incidence of variations in the length, course, and termination of cystic duct in cadavers. Materials and Methods: Present study was done in 50 adult cadavers in the Department of Anatomy, Government Tiruvannamalai medical college, Tamilnadu. Meticulous dissection was done in the hepatobiliary system of these cadavers. Observations: During the study variations in the length of cystic duct, course and different modes of insertion of cystic duct were observed. Conclusion: Knowledge of variations in the length of cystic duct and knowing about different modes of course & insertion of cystic duct is necessary for surgeons while conducting cholecystectomy. The risk of iatrogenic injury is especially high in cases where the biliary anatomy is misidentified prior to surgery. KEY WORDS: Cystic duct, Gallbladder, Cholecystectomy.

AbstractLeft sided gallbladder is a rare anomaly that is often associated with other abnormal anatomy in the hepatobiliary system. One left positioned gallbladder was found in a consecutive series of 3290 patients undergoing laparoscopic cholecystectomy for gallstone disease in the Mure County Emergency Hospital’s 2nd Surgery Clinic between 2005 and 2015, a prevalence of 0.03 per cent. In case of left sided gallbladder the cystic artery always crosses in front of the common bile duct from right to left. The cystic duct may open on the left or right side of the common hepatic duct. Anterograde cholecystectomy is the best choice for precise exploration of the cystic duct and cystic artery.

Gallstone disease is the most common risk factor for cholangitis. In an anatomically normal bile duct system, cholangitis does not occur without the presence of stones. Endoscopic retrograde cholangiography with papillotomy and stone extraction is a well-established curative therapy for gallstones in the common bile duct. More important, papillotomy prevents recurrent episodes. The present case report describes a 73-year-old male with recurring cholangitis in a clear bile duct system after previous papillotomy. An etiology of duodenal reflux into the common bile duct due to heavy lifting is proposed.

The right hepatic artery is an end artery and contributes sole arterial supply to right lobe of the liver. Misinterpretation of normal anatomy and anatomical variations of the right hepatic artery contribute to the major intraoperative mishaps and complications in hepatobiliary surgery. The frequency of inadvertent or iatrogenic hepatobiliary vascular injury rises with the event of an aberrant anatomy. This descriptive study was carried out to document the normal anatomy and different variations of right hepatic artery to contribute to existing knowledge of right hepatic artery to improve surgical safety. This study conducted on 60 cadavers revealed aberrant replaced right hepatic artery in 18.3% and aberrant accessory right hepatic artery in 3.4%. Considering the course, the right hepatic artery ran outside Calot’s triangle in 5% of cases and caterpillar hump right hepatic artery was seen in 13.3% of cases. The right hepatic artery (normal and aberrant) crossed anteriorly to the common hepatic duct in 8.3% and posteriorly to it in 71.6%. It has posterior relations with the common bile duct in 16.7% while in 3.4% it did not cross the common hepatic duct or common bile duct. The knowledge of such anomalies is important since their awareness will decrease morbidity and help to keep away from a number of surgical complications.

A 33-year-old female with a mild elevation of liver transaminase was sent to the general surgery department for medical services due to upper-right abdominal pain for 2 weeks. A liquid dark area ~4 × 3 × 3 cm in size in the theoretical location of the pancreatic segment of the common bile duct was detected by abdominal CT with no enhancement of the cystic wall found in the enhanced CT scan. The patient was then diagnosed with a choledochal cyst based on the results of the radiological images preoperatively. During the operation, the isolated cystic dilatation was found in the middle part of the cystic duct, and its caudal portion was found behind the head of the pancreas and converged into the common bile duct at an acute angle and low insertion. According to the intraoperative evaluation, the female was then diagnosed with a cystic duct cyst (CDC). The surgery was converted to a laparotomy for the unclear structure and the possibility of anatomic variation of the bile duct. The caudal portion of the cystic duct was found communicated with the common bile duct with a narrow base, and the extrahepatic bile duct was not cystic. The CDC was removed in the surgery. One week later, the patient was discharged from the hospital for the disappearance of abdominal pain and normal liver transaminase and did not report any discomfort in the 1-month-long follow-up. The lessons drawn from this case were as follows: (1) the distinction between the relatively frequent choledochal cyst and the isolated CDC should always be taken in mind; (2) a surgical strategy should be given priority for an intraoperatively confirmed CDC; (3) a common bile duct exploration is recommended for patients with choledocholithiasis or jaundice.

Objectives: Use to ultrasound vibrations instead of electric current makes Harmonic Scalpel a safer and more efficient instrument for dissection during laparoscopic surgeries. The property of both coagulation and cutting using single Harmonic Scalpel instruments saves time of surgery reducing anesthesia load. Cystic artery and liver bed dissection has been widely used and established but a contemporary approach is the coagulation and cutting of cystic duct with Harmonic Scalpel eliminating the need for clips and reducing the epigastric port size from 10mm to 5mm thus reducing post-operative pain. Study Design: Prospective Study. Setting: This study was conducted in Department of surgery Quaid e Azam Medical College Bahawalpur. Period: Dec, 2015 to Dec, 2017. Material & Methods: 60 patients undergoing laparoscopic cholecystectomy 3 ports were introduced one 10mm and two 5mm. the dissection and division of both cystic artery and duct was done by a single instrument, Harmonic Scalpel after tying the cystic duct with 2/0 extracorporeal knot. Results: None of the patients developed Major or Minor bile leaks or hemorrhage. Conclusion: Harmonic scalpel provides a safe alternative for dissecting and division of cystic duct and may replace the more widely used clip technique. The number of ports can be reduced to 3 and size reduced from 10mm to 5 mm. Harmonic scalpel technique eliminates the time wasted during changing of instruments per-operatively and also reduces the risk of remote electric injury.

Background: Major complications of laparoscopic cholecystectomy are bleeding and bile duct injury, and it is necessary to clearly identify structures endoscopically to keep bleeding and injury from occurring. The aim of this study was to depict the anatomic landmark in the Calots triangle, a vein (cystic vein), a constant feature which can help Laparoscopic surgeons to conduct a safe LC along with other precautions to be adopted. Methods: A total of 100 patients (58 male, 42 female) who underwent cholecystectomy were examined preoperatively by clinically. The origin and number of cystic veins and their relationship with the Calot triangle was evaluated. Results: The cystic veins were delineated intraoperatively in 80 of the 93 patients. The relationship between the cystic vein and the Calot triangle was identified in 80 (86.02%) of the 93 patients. One cystic vein was found in 53 (66.25%) patients, while multiple cystic veins were found in 27 (33.75%) patients. All these veins are above the cystic common bile duct junction. Conclusion: The configuration of the cystic veins and their relationship in the Calot triangle with cystic artery and cystic duct can be identified intraoperatively and used as a guideline for safe laparoscopic cholecystectomy.

Abstract Background Normal biliary anatomy is uncommon. Different classification for biliary anatomy has been described, with Huang Types A4 & A5 of great interest for laparoscopic cholecystectomy (LC) due to the proximity of aberrant bile duct to Cystic duct (CD). These types of dangerous anatomy might contribute to bile duct injury. This study aims to analyse the prevalence of dangerous biliary anatomy. Methods Prospectively collected data for all patients who underwent laparoscopic cholecystectomy was analysed. All LC were performed by single surgeon or under  his direct supervision, between 01/07/2020 and 20/08/2021. Index admission and single session management of cholelithiasis disease with routine Laparoscopic cholecystectomy + intra operative cholangiography (IOC) +/- LCBD exploration were standard practice. Results Laparoscopic cholecystectomy was performed in 137 patients. Mean age was 56y (17-84).  62% were females.   66% of Laparoscopic cholecystectomies were emergency. IOC was performed in 92% of cases. Abnormal biliary anatomy was found in 54% : Huang A1 - 48%, A2 - 29%, A3 - 12%, A4 - 9.7% and A5 - 0.7%. Dangerous anatomy (A4 and A5) was found in 10.5%, 78 % were females.  Female with dangerous anatomy were younger than males 49 y, 60y respectively. Nassar difficulty grading for dangerous anatomy was as follows: G2 28%, G3 42% and G3 28% Abnormal cholangiogram was found in 48%, due to filling defect in 58%, no contrast flow into duodenum in 4%, Cystic duct stone in 4%, and short CD in 8%. CBD stones were treated using transcystic approach in 92% of cases. No intra-operative or post operative complications were recorded for patients with dangerous anatomy.  Conclusions This study demonstrates that dangerous biliary anatomy, that could lead to bile duct injury is relatively common, occurring in 10.7% of LCs. Routine intra-operative cholangiography highlights these high-risk variations in biliary anatomy and may prevent inadvertent bile duct injury in such cases.
