Abstract

This article presents a clinical case of obstructive colitis (OC). Initial diagnosis indicated septic shock and multi-organ failure due to peritonitis. Imaging studies revealed diffuse colonic dilation and signs of mucosal ischemia. During surgery, the entire colon was found to be necrotic up to the serosal layer, with a high rectal ring-shaped tumor identified as the cause of obstruction. Surgical intervention included subtotal colectomy, ileostomy and abdominal lavage, followed by postoperative antibiotic therapy and critical care support. Histopathological analysis confirmed the tumor as a high-grade tubular adenocarcinoma, with hallmark features of OC, such as mucosal ulceration and acute inflammation. The article provides an in-depth overview of the pathogenesis, clinical presentation, imaging findings, and histological characteristics of obstructive colitis. It underscores the rarity of OC and its potential for severe complications if left undiagnosed or untreated. The authors propose surgical management strategies to mitigate postoperative complications, including meticulous inspection of affected colonic segments and wider resections if necessary. This case highlights the critical importance of early diagnosis and timely intervention in OC, particularly in patients with colorectal cancer.
