Rectal Fistula Causing NSTI of the Right Gluteal Region and Thigh after Colonoscopy
Keywords:
NSTI, Rectal fistula, Gluteal region, thigh, endoscopyAbstract
Necrotizing soft-tissue infections (NSTI) are severe and rapidly progressing bacterial infections that carry high mortality. We are presenting a unique case of NSTI following colonoscopy associated with rectal carcinoma in a man on his mid-60s who noticed swelling and pain in his right lower extremity four days following a colonoscopy. The patient was diagnosed with NSTI and underwent surgical debridement. Three days after surgical intervention, the colonoscopy report returned confirming rectal cancer, which may have contributed to NSTI development. This case highlights a rare but serious complication following colonoscopy, emphasizing the need for clinicians to consider NSTI in patients with malignancy and immunocompromised conditions who present with signs of sepsis and soft-tissue infection after endoscopic procedures.
