title: Technical notes: a self-designed, simple, secure, and safe six-loop intracorporeal Pringle's maneuver for laparoscopic liver resection.
abstract: BACKGROUND
  The aim of this study is to design a simple, secure, and safe technique of intracorporeal Pringle's maneuver to facilitate safer laparoscopic liver resection.
  
  
  METHODS
  A self-designed six-loop catheter was made using 20-French T-tube and 10-French nelaton urethral catheter. The cross head and stem of the T-tube were trimmed to 1 cm, respectively. The nelaton was shortened to 12-cm-long tube from the round tip, and the cut end was inserted and sutured to the stem of the T-tube. After establishment of pneumoperitoneum, the T-tube with nelaton was placed into the abdomen. The round end of the nelaton was inserted into the lesser sac and pulled through the foramen of Winslow, and the end of nelaton was then inserted into one end of the T-tube and pulled through the other end, forming a six-loop. The nelaton was pulled to occlude the hepatic inflow and temporarily fixed with 1-0 Vicryl on a curved round needle on the other end of the T-tube. The protocol of Pringle's maneuver was 15-min clamp and 5-min release periods. The liver parenchymal transection was performed using Harmonic scalpel.
  
  
  RESULTS
  From November 2009 to August 2011, 20 patients received laparoscopic liver resection using the six-loop Pringle's maneuver. During operation, 17 patients were positioned supine, 2 patients in left decubitus, and 1 patient in supine followed by left decubitus position. There were 9 anatomical resections and 11 nonanatomical resections (18 patients for single lesion, 1 for two lesions, and 1 for three lesions). The average times of liver resection and Pringle's maneuver were 33.1 and 36.2 min, respectively. Mean blood loss was 102.5 ml. The postoperative course was uneventful, and average hospital stay was 4.4 days.
  
  
  CONCLUSIONS
  Our self-designed six-loop intracorporeal Pringle's maneuver can facilitate safer laparoscopic liver resection.
