Surgery for diverticular peritonitis

Area of Science:

• Gastroenterology
• Surgical Gastroenterology
• Emergency Medicine

Background:

• Acute diverticulitis can lead to colonic perforation and peritonitis, classified by the Hinchey system.
• Hinchey III and IV peritonitis represent severe presentations requiring urgent surgical intervention.
• Sepsis management is critical in patients with perforated diverticulitis.

Purpose of the Study:

• To review the surgical management strategies for Hinchey III and Hinchey IV diverticular peritonitis.
• To evaluate the efficacy and outcomes of different surgical approaches.
• To discuss the role of minimally invasive techniques and primary anastomosis.

Main Methods:

• Literature review of surgical management for Hinchey III and IV diverticular peritonitis.
• Analysis of supporting evidence for various surgical options.
• Discussion of outcomes, including survival rates and stoma formation.

Main Results:

• Laparoscopic Peritoneal Lavage is a viable alternative to laparotomy-colectomy for Hinchey III peritonitis.
• The Hartmann's operation offers no survival advantage and often leads to permanent stomas.
• Evidence supports on-table colonic lavage and primary anastomosis in most cases, except for critically ill patients.

Conclusions:

• Prompt surgical intervention and sepsis management are crucial for Hinchey III and IV diverticular peritonitis.
• Minimally invasive approaches like laparoscopic lavage are gaining prominence.
• Primary anastomosis, when feasible, is preferred over procedures with high rates of permanent stoma formation.
