Management of Stomal Ischemia and Dusky Stoma

Indications for Emergency Relaparotomy

In patients with a dusky stoma, the presence of bowel perforation or peritonitis warrants immediate emergency relaparotomy to prevent further morbidity. 1

When operating for stomal ischemia, surgeons should resect only bowel that is clearly necrotic and apply damage‑control techniques (e.g., limited resection, rapid control of contamination) to minimize physiologic stress. 1
A planned second‑look laparotomy at 24–48 hours after the initial operation is recommended to reassess bowel viability and avoid unnecessary removal of marginally viable intestine. 1

If the stoma appears “dusky” but not definitively necrotic, temporary abdominal closure using negative‑pressure wound therapy is advised to protect the bowel while allowing reassessment. [1][2]
The operative note must include a precise documentation of the remaining bowel length to guide future management and prevent inadvertent short‑bowel complications. 2

Excessive crystalloid infusion should be avoided because it can precipitate abdominal compartment syndrome, which worsens stomal perfusion. 1
Serial monitoring of lactate clearance and central venous oxygen saturation provides objective indicators of adequate systemic and tissue perfusion while the stoma is being evaluated. 1

Proper pouching systems should be employed during the assessment period to prevent peristomal skin breakdown from leakage. 3
The opening of the stoma appliance should be cut approximately one‑eighth of an inch larger than the stoma diameter to reduce mucosal irritation and secondary discoloration. 3

Elective stoma revision should not be performed before six weeks after the initial surgery unless there is an emergent indication (e.g., full‑thickness necrosis), because early revision is associated with a higher complication rate. 3

Purple or dark discoloration of the stoma is a medical emergency requiring immediate surgical evaluation, as it indicates stomal ischemia from compromised blood supply, which requires emergency surgery 4, 5
Acute stomal prolapse leading to incarceration and ischemia can present with pain, obstipation, and purple/black discoloration, and requires urgent surgical intervention 4, 5
Dark red or purple coloration is never normal and suggests tissue compromise, indicating the need for immediate assessment by the surgical team 4, 5
The American Gastroenterological Association recommends that any deviation from a bright red, moist stoma appearance, such as purple discoloration, warrants immediate reporting to the surgical team, as it specifically indicates severe ischemia and impending tissue necrosis 4, 5
