Madany Triangle; a New Era of Laparoscopic Cholecystectomy

Operative procedure: This technique was different from the ordinary laparoscopic cholecystectomy in the following steps: with the aid of electrocautery Hook, the dissection started first with the peritoneum, which covered both sides of the Hartman pouch, the proximal third of the gallbladder (the area of the gallbladder at its neck), and the proximal part of the cystic duct (the end of the cystic duct which was attached to the gallbladder neck). With using a grasper for manipulating the Hartman pouch for better dissection of the gallbladder bed. Then gently dissecting the gallbladder from its bed to skeletonize it away from the cystic plate and porta hepatis. The small branches of cystic artery that were dipping in the GB wall were cauterized one by one. This step involved scarification of the cystic artery, and its branches, which necessitated the use of bipolar diathermy. Now, after dissection of the proximal part of the gallbladder from its bed and scarification of the cystic artery and its branches, the traction applied to the Hartman pouch created an angle between the skeletonized cystic duct and the skeletonized posterior surface of the GB. Also, this traction creates a dynamic triangle visualized from both the left and right sides according to the traction applied to the Hartman pouch to the right or left and the direction of the angled scope of the camera lens. From the left-side view, when right traction is applied to the Hartman pouch, it is bound laterally by the skeletonized proximal part of the cystic duct. Superiorly, it is bound by the posterior surface of the proximal part of the skeletonized gallbladder. It was bounded medially by an imaginary line between a point at the junction of the cystic duct with the CBD and a point at the anterior end of the dissected cystic plate (the Madany triangle). From the right-side view, when left traction was applied on the Hartman pouch, the triangle was bounded by the proximal part of the dissected cystic duct medially. It was bound superiorly by the posterior surface of the proximal third of the skeletonized gallbladder. Laterally, it was bounded by an imaginary line between a point at the junction of the cystic duct with the CBD and another point located at the anterior end of the dissected cystic plate. A Vicryl (2-0) ligature or a titanium clip was applied to the cystic duct immediately distal to the Hartman pouch after gentle milking of the cystic duct to exclude the presence of stones inside. The GB was removed from the peritoneal cavity with the use of a bag.
