Copious Irrigation Versus Suction Alone During Laparoscopic Appendectomy for Complicated Appendicitis in Adults

Area of Science:

• Surgical Innovation
• Gastrointestinal Surgery
• Clinical Trials

Background:

• Complicated appendicitis poses risks of postoperative complications.
• Laparoscopic appendectomy is a common surgical approach.
• The role of peritoneal irrigation versus suction alone in managing complicated appendicitis requires clarification.

Purpose of the Study:

• To evaluate the efficacy of copious peritoneal irrigation during laparoscopic appendectomy for complicated appendicitis.
• To compare postoperative complication rates and recovery between irrigation and suction-only groups.
• To assess the impact on wound infection, intra-abdominal abscess, and recovery metrics.

Main Methods:

• Prospective randomized trial involving 260 adult patients with complicated appendicitis.
• Patients were assigned to either irrigation and suction (IS) or suction only (SO) groups.
• Standardized 3-port laparoscopic approach with a minimum of 2000 mL sterile normal saline irrigation in the IS group.

Main Results:

• Copious irrigation led to a longer operation time (p <0.001) but significantly reduced the rate of postoperative intra-abdominal abscess (3.1% vs. 9.2%, p = 0.039).
• The irrigation group experienced earlier anal exsufflation (p = 0.011), shorter hospital stay (p <0.001), and lower hospital charges (p <0.001).
• No significant difference in wound infection rates was observed between the groups.

Conclusions:

• Copious peritoneal irrigation during laparoscopic appendectomy for complicated appendicitis effectively decreases the incidence of postoperative intra-abdominal abscess.
• This irrigation technique promotes faster postoperative recovery and results in reduced hospital charges.
• Peritoneal irrigation is a beneficial adjunct in managing complicated appendicitis laparoscopically.
