title: [A modeling method for laparoscopic left lateral segment liver resection: report of 71 cases].
abstract: OBJECTIVE
  To summarize the experience with a modeling method for laparoscopic left lateral segment liver resection (LLLR).
  
  
  METHODS
  The surgical procedures of LLLR were carried out with the patient placed in a supine position and 4 trocars placed on the abdomen. After complete dissociation of the left lobe, the segment II and III vascular pedicles were freed with a harmonic scalpel and transected with a linear cutter stapler. The left hepatic vein (LHV) was dissociated with a harmonic scalpel with a slightly left direction of liver dissection, followed by complete resection of the LHV and finally by wound surface management, specimen removal, wound drainage, and abdominal incision closure.
  
  
  RESULTS
  Between July, 2003 and August, 2010, this modeling method for LLLR was performed successfully in 48 cases without conversion to laparotomy. The mean operation time was 75∓30.8 min, blood loss was 58∓36.4 ml, and length of postoperative hospital stay was 4.8∓1.5 days. Postoperative complications occurred in 3 cases, including ascites in 2 cases and mild biliary leakage 1 case, all cured conservatively.
  
  
  CONCLUSIONS
  This modeling method can simplify the surgical procedure of LLLR, reduce blood loss, and avoid air embolism due to vein injury. Being less technically demanding, this method can be safely performed in hospitals at various levels.
