Perforated appendicitis: is laparoscopic operation advisable?

Area of Science:

• Surgical Innovation
• Gastrointestinal Surgery
• Minimally Invasive Procedures

Background:

• Perforated appendicitis presents a surgical challenge with potential for complications.
• Traditional open appendectomy carries risks of wound infection and other morbidities.
• Laparoscopic techniques offer potential advantages in managing complex intra-abdominal conditions.

Purpose of the Study:

• To compare the outcomes of laparoscopic appendectomy versus open operation for perforated appendicitis.
• To evaluate complication rates, including wound infections and intra-abdominal abscesses.
• To determine the safety and efficacy of laparoscopic appendectomy in specific patient subgroups, such as obese individuals.

Main Methods:

• A retrospective analysis of 734 patients undergoing appendectomy for acute appendicitis between 1991 and 1999.
• Focus on 125 patients with perforated appendicitis, comparing laparoscopic (n=80) and open (n=45) procedures.
• Analysis included conversion rates, operating times, wound infections, intra-abdominal abscesses, and mortality.

Main Results:

• Laparoscopic appendectomy showed a significantly lower rate of wound infection (2%) compared to converted (22%) and open (18%) procedures.
• Intra-abdominal abscess rates were similar across all groups (5-8%).
• Fatal outcomes (11%) were exclusively observed in patients who underwent open operation for severe peritonitis.

Conclusions:

• Laparoscopic appendectomy is associated with fewer septic wound complications in perforated appendicitis.
• The benefits are particularly notable in obese patients.
• Laparoscopic appendectomy is recommended for perityphlitic abscess or purulent lower abdominal peritonitis, excluding generalized peritonitis.
