Comparing Hartmann's Procedure and Primary Resection with Anastomosis in Hinchey III-IV Diverticulitis: Focus on Ostomy Closure and Long-Term Outcomes

Detailed Description

This multicenter study evaluates and compares the outcomes of primary anastomosis with diverting loop ileostomy and Hartmann's procedure in the surgical management of perforated sigmoid diverticulitis in stable patients. Conducted across multiple surgical centers, the study provides a comprehensive overview of these approaches in real-world clinical settings. The findings indicate that primary anastomosis with diverting loop ileostomy demonstrates significant advantages over Hartmann's procedure, particularly in terms of long-term outcomes, stoma management, and recovery metrics.

Patients who underwent primary anastomosis with diverting loop ileostomy achieved notably higher stoma reversal rates (92% versus 58%), a shorter median time to stoma closure, and fewer stoma-related complications such as parastomal hernias. These results underscore the benefits of restoring bowel continuity, which plays a critical role in improving both physical functionality and psychological well-being. Kaplan-Meier analysis confirmed superior stoma-free survival rates at 24 months for patients receiving primary anastomosis with diverting loop ileostomy compared to those treated with Hartmann's procedure.

While Hartmann's procedure remains a valuable option for unstable or critically ill patients due to its simplicity, its long-term disadvantages include a higher prevalence of stoma-related complications, such as parastomal hernias and challenges with colostomy management. Conversely, primary anastomosis with diverting loop ileostomy was associated with a slightly higher rate of early readmissions, often due to issues related to the protective ileostomy, including dehydration and electrolyte imbalances. However, these complications were generally manageable with appropriate follow-up care.

The study also highlights shorter hospital stays and faster recovery times for patients treated with primary anastomosis with diverting loop ileostomy, contributing to reduced healthcare costs and improved quality of life. These findings suggest that primary anastomosis with diverting loop ileostomy should be considered a first-line option for stable patients, with Hartmann's procedure reserved for those in critical conditions. Future research is recommended to further investigate minimally invasive techniques, long-term quality of life outcomes, and randomized controlled trials to solidify these findings and refine surgical practices.
