Acute appendicitis and continuous peritoneal lavage

Area of Science:

• Surgical Innovation
• Gastrointestinal Surgery
• Infectious Disease Management

Background:

• Acute appendicitis with perforation is a serious surgical condition.
• High morbidity and complication rates are associated with perforated appendicitis.
• Standard treatment involves appendicectomy, but further interventions are explored to improve outcomes.

Purpose of the Study:

• To evaluate the efficacy of continuous peritoneal lavage in reducing morbidity and complications following appendicectomy for perforated appendicitis.
• To assess the impact of immediate postoperative peritoneal lavage on patient recovery.
• To determine the optimal duration and volume of peritoneal lavage in this patient cohort.

Main Methods:

• A series of 117 patients with acute appendicitis and perforation underwent appendicectomy.
• Continuous peritoneal lavage was initiated immediately after surgery.
• Treatment involved approximately 40 liters of dialysate per patient over an average of 18 hours, continuing until effluent was macroscopically clean.

Main Results:

• Continuous peritoneal lavage demonstrated a significant reduction in the morbidity rate.
• The complication rate associated with perforated appendicitis was notably decreased.
• The treatment protocol was well-tolerated, with lavage continuing until macroscopic cleanliness of peritoneal fluid was achieved.

Conclusions:

• Immediate postoperative continuous peritoneal lavage is an effective adjunctive therapy for perforated appendicitis.
• This method significantly lowers complication rates and improves patient outcomes.
• Peritoneal lavage offers a valuable approach to managing the infectious and inflammatory sequelae of perforated appendicitis.
