An "all 5-mm ports" selective approach to laparoscopic cholecystectomy, appendectomy, and anti-reflux surgery.

Laparoscopic appendectomy, cholecystectomy, or anti-reflux procedures are conventionally performed with the use of one and often two 10/12-mm ports. While needlescopic or micropuncture laparoscopic procedures reduce postoperative pain, they invariably involve the use of one 10/12-mm port and the instruments applied have their ergo-dynamic shortcomings. Between September 2002 and March 2003, we have attempted an "all 5-mm ports" approach in 49 laparoscopic procedures, which included 18 of 59 laparoscopic cholecystectomies (31%), 26 diagnostic laparoscopies for suspected appendicitis (of which we proceeded to a laparoscopic appendectomy in 17 patients), and in the last 5 of 9 laparoscopic Nissen fundoplications. Conversion of one of the 5-mm ports to a 10-mm port was required in 5 of the 18 (28%) laparoscopic cholecystectomies and in 6 of the 17 (35%) laparoscopic appendectomies to facilitate organ retrieval in patients with large gallstones (>5 mm in diameter) and in obese patients with fatty mesoappendix. There were no conversions to open surgery. No significant differences in the operating time between the laparoscopic procedures performed by the all 5-mm ports approach or the conventional approach were observed. No intraoperative or postoperative complications occurred in this series. The "all 5-mm ports" approach to laparoscopic cholecystectomy and appendectomy in selected patients and to laparoscopic fundoplication appears feasible and safe. A randomised comparison between this approach and the conventional laparoscopic approach to elective cholecystectomy and fundoplication in which two of the ports employed are of the 10-mm diameter is warranted.
