Initial nonoperative management for periappendiceal abscess

Area of Science:

• Gastroenterology
• Surgical Innovation
• Clinical Outcomes

Background:

• Appendicitis is a common surgical emergency.
• Periappendiceal abscess is a serious complication of appendicitis.
• Management strategies include operative and nonoperative approaches.

Purpose of the Study:

• To compare initial operative versus nonoperative management for periappendiceal abscess.
• To evaluate the safety and efficacy of nonoperative treatment.
• To assess complication rates and recurrence in patients with periappendiceal abscess.

Main Methods:

• Retrospective review of 155 patients with periappendiceal abscess.
• Patients treated between 1992 and 1998.
• Comparison of initial nonoperative (88 patients) versus operative (67 patients) management.

Main Results:

• No significant differences in length of stay, normalization of white blood cell count, temperature, or diet tolerance between groups.
• Nonoperative management had a significantly lower complication rate (17% vs. 36%).
• Initial nonoperative management showed a 5.8% failure rate and an 8% appendicitis recurrence rate.

Conclusions:

• Initial nonoperative management of periappendiceal abscess is safe and effective.
• Nonoperative approach reduces complication rates.
• Patients managed nonoperatively have an increased risk of recurrent appendicitis.
