Abstract:
Purpose: Current society guidelines recommend purse-string closure technique for stoma reversal, which has been shown to reduce but not eliminate the risk of deep surgical site infection (SSI) at the original stoma site, a complication associated with increased morbidity and cost. We studied an adjunctive technique to further reduce the risk of SSI. Methods: A retrospective chart review was conducted on adult patients who underwent stoma reversal between May 2016 - July 2022. Stoma reversal was performed with purse-string closure, and placement of a strip of povidone-iodine soaked non-adherent pad in the remaining two cm opening at the prior stoma site. This pad was taken out on post-operative day one and changed to wet-to-dry saline moistened gauze. Results: 82 patients were identified. The cohort had a median BMI 26.5 [IQR 23.0-31.0] and median age 57.5 [IQR 45.8-67.0]. Mean time from original surgery to reversal was nine months. 59.8% identified as female, 24.4% were currently smoking, 18.3% were had diabetes. The cohort experienced a 11.0% readmission rate and 18.3% rate of stoma site hernia with a mean follow up of 17 17 months. No patient developed an SSI. Conclusion: In this cohort study with known risk factors for SSI, no patients undergoing stoma reversal experienced a post-operative SSI. The adjunctive technique of a povidone-iodine soaked non-adherent pad in addition to purse-string closure should be further examined in conjunction with surgical bundles to reduce the risk of SSI and overall morbidity of stoma reversal surgery.

Ostomy 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:
Inflammatory Bowel Disease V: Surgical Management
Here are some common surgical interventions for IBD:
Tracheostomy Decannulation
Description of the Procedure
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...

Clinical Manifestations:
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
