Introduction:
Despite the shift toward liberal primary anastomosis in penetrating colon injuries, some surgeons recommend a protective diverting ostomy (DO) proximal to the anastomosis. This study evaluates the effect of DO on outcomes in patients undergoing colon resection and anastomosis following penetrating trauma.
Methods:
The TQIP database (2013-2018) was queried for penetrating colon injuries undergoing colectomy and anastomosis. Patients receiving DO were propensity matched to patients without diverting ostomy (woDO) (1:3). Outcomes were compared between groups.
Results:
After matching, 89 DO patients were analyzed. The DO group had more surgical site infections (32 % vs. 21 %; p < 0.05) and longer hospital stay (20 [13-27] vs. 15 [9-25]; p < 0.05) compared to the woDO group. Mortality and unplanned operations were similar between groups.
Conclusions:
Diverting ostomy after colon resection and anastomosis is associated with increased infectious complications without decreasing unplanned operations or mortality. Its routine role in penetrating colon trauma needs reassessment.

01:24Ostomy Care
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:

Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
