Current analysis of endoloops in appendiceal stump closure

Area of Science:

• Surgical Innovation
• Gastrointestinal Surgery
• Minimally Invasive Procedures

Background:

• Inadequate appendiceal stump closure can lead to intra-abdominal surgical site infections.
• Staplers are often cited for reducing infection risk, but randomized studies on abscess or wound infection rates are limited.
• This study evaluates complications associated with endoloop use in appendiceal stump closure at a high-volume center.

Purpose of the Study:

• To assess the safety and efficacy of endoloops for appendiceal stump closure in laparoscopic appendectomy.
• To compare complication rates, specifically intra-abdominal abscesses, between endoloop and stapler methods.
• To determine the cost-effectiveness of endoloop stump closure.

Main Methods:

• Prospective data collection from 1,790 patients undergoing laparoscopic appendectomy (January 1998 - December 2006).
• Standard procedure involved endoloop stump closure with selective stapler use.
• Outcome criteria included intra-abdominal abscess formation, other complications, and operational costs.

Main Results:

• Laparoscopic appendectomy was performed in 80.8% of patients; 19.2% underwent open appendectomy.
• Endoloops were used for stump closure in 97.3% of laparoscopic cases (n=1,670), with staplers used in 2.7% (n=46).
• No significant difference in intra-abdominal abscess rates was observed between endoloop and stapler groups across different appendicitis severities (e.g., acute, perforated).

Conclusions:

• Endoloop appendiceal stump closure is a safe and effective method for routine clinical practice.
• The selective use of endoloops for stump closure is well-established and reliable.
• Endoloop closure offers an easy, safe, and cost-effective surgical option.
