Gas-Free Single-Port Transumbilical Laparoscopic Cholecystolithotomy: Preliminary Report on Eight Cases

Abstract

Abstract

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 CO₂ in the body and its potential side effects.
