Intraoperative revelations necessitated a carcinologic right colectomy and the creation of an end-loop ileocolostomy. Following six sessions of adjuvant chemotherapy, Computed tomography scans raised uncertainties about the presence of peritoneal carcinomatosis. Consequently, a collaborative decision was reached in a multidisciplinary discussion to conduct a surgical biopsy of these deposits before reinstating digestive continuity. The surgical procedure started with stoma mobilization. However, adhesions and a relatively confined aperture curtailed a comprehensive peritoneal cavity exploration. Thus, a midline incision was executed. The verdict from the frozen section examination affirmed metastatic presence, prompting the retention of the stoma. Within 48 h post-surgery, an early-stage parastomal evisceration occurred, stemming from an inadequately sealed aponeurotic sheath. The exposed bowel surface was encased in fibrin, necessitating meticulous irrigation with a warm saline solution before repositioning it within the peritoneal cavity.
