Background:
To explore the feasibility and safety of gas-free single-port transumbilical laparoscopic cholecystolithotomy.
Methods:
An incision of 1.5-2.0 cm was made through all layers of the umbilicus, and a specially designed silicone plug with three 5-mm ports was inserted. The surgical space was created by lifting the right abdominal wall with an abdominal suspension set. A laparoscope, S-type dissector, grasper,electric needle, and needle-holder were used to perform a cholecystolithotomy. The procedure was performed in 8 patients with gall stones.
Results:
All stones were successfully removed. No postoperative complications, such as bleeding or bile leakage, occurred. The operative time was 45-120 minutes (mean 77.5 ± 24). The mean length of hospital stay was 2 days, and no postoperartive analgesics were used. There were no visible scars on the abdominal wall.
Conclusions:
The gas-free single-port transumbilical laparoscopic approach was safe and feasible for cholecystolithotomy. This approach expands the applications of laparoendoscopic single-site surgery and avoids the use of highly concentrated CO(2) in the body and its potential side effects.
