A Simple Method of Liver Retraction for Various Types of Laparoscopic Upper Gastrointestinal Surgeries: The Prolene Hanging-Up Method.

This study describes a safe and the simple method for liver retraction during various types of laparoscopic upper gastrointestinal surgeries. The technique was performed using only a 75 cm 2-0 prolene suture, which was passed through the abdominal wall with a straight needle at the two points of the epigastrium and at the pars condensa of the gastrohepatic ligament without any protective material or knotting. Seventy-six patients who underwent various types of laparoscopic upper gastrointestinal surgeries from August, 2012 to March, 2013 at Incheon St. Mary's Hospital were included in the study. The mean time for the liver retraction was 2.7 ± 0.6 min. Among the 76 cases, complication of this method was one case of the puncture site bleeding on the abdominal wall. The mean levels of alanine aminotransferase and aspartate aminotransferase on the day of the surgery were 54.9 ± 26.3 U/L and 45.2 ± 23.1 U/L, respectively, and these had decreased to 22.4 ± 13.2 U/L and 21.8 ± 14.0 U/L, respectively, on the fourth postoperative day. The prolene hanging-up method is very simple and safe, and it can be used in various types of laparoscopic upper gastrointestinal surgeries.
