title: Visualisation of Rouviere's Sulcus during Laparoscopic Cholecystectomy.
abstract: BACKGROUND
  Safe dissection of Calot's Triangle is important during the performance of laparascopic cholucystectomy. The purpose of the study is to determine the frequency of demonstrable Rouviere's sulcus in patients with symptomatic gall stones and its role in safe dissection in Calot's triangle.
  
  
  METHODS
  This is a prospective descriptive study design done in Department of surgery, Kathmandu Medical College Teaching Hospital from Jan 2013 to Jan 2015. Patients who were posted for laparoscopic cholecystectomy were included. During laparoscopy, Rouviere's sulcus was noted in the operative note and classified according to following: Type I: Open type was defined as a cleft in which the right hepatic pedicle was visualized and the sulcus was opened throughout its length. Type II: if the sulcus was open only at its lateral end. Type III If the sulcus was open only at its medial end. Type IV: Fused type was defined as one in which the pedicle was not visualized.
  
  
  RESULTS
  A total of 200 patients underwent laparoscopic cholecystectomy during period of 2 years. Out of which Rouviere's sulcus was visualized in 150 patients (75 %).Type I (open type) was commoner in 54%, type II in 12%, Type III in 9% and type IV (fused type) in 25%.
  
  
  CONCLUSIONS
  Rouviere's Sulcus is an important extra biliary land mark for safe dissection of Calot's triangle during laparoscopic cholecystectomy.
