Wound infection after ileostomy closure: a prospective randomized study comparing primary vs. delayed primary closure...

Area of Science:

• Surgical site infection prevention
• Gastrointestinal surgery outcomes

Background:

• Ileostomy closure is a high-risk operation with infection rates exceeding 30%.
• Delayed primary closure is a common technique to reduce stoma wound infections.
• Previous studies on delayed primary closure were retrospective.

Purpose of the Study:

• To compare primary closure versus delayed primary closure for ileostomy wounds.
• To determine the optimal wound closure technique for reducing stoma site infections.
• To present the first prospective randomized trial on this surgical comparison.

Main Methods:

• A prospective randomized trial involving 40 patients undergoing ileostomy closure.
• Patients were divided into two groups: Group 1 (delayed primary closure, n=20) and Group 2 (primary closure, n=20).
• The same surgical team and technique were used, differing only in wound closure method.

Main Results:

• The overall wound infection rate was 15%.
• Delayed primary closure (Group 1) had a 20% infection rate (4 cases).
• Primary closure (Group 2) had a 10% infection rate (2 cases), with similar hospital stays for both groups.

Conclusions:

• Primary closure of ileostomy wounds unexpectedly resulted in a lower infection rate compared to delayed primary closure.
• This study suggests primary closure may be a superior technique for managing stoma wounds.
• Further research may validate primary closure as the preferred method for ileostomy takedown.
