Guidelines for Diagnosis and Immediate Management of Strangulated Rectal Prolapse

Clinical Recognition of Strangulation

Visual inspection of the prolapsed rectal segment may reveal gangrenous or necrotic tissue, indicating loss of blood supply and impending bowel death. 2
The prolapsed segment often becomes irreducible and edematous, failing manual reduction even when sedation or anesthesia is used. 3
Prolonged strangulation can lead to ulceration and perforation of the prolapsed mucosa. 2
Hemodynamic instability (e.g., hypotension, tachycardia, shock) signals advanced tissue necrosis with systemic compromise. [1][4]
Leukocytosis is commonly observed (except in immunocompromised or steroid‑treated patients) and serves as a predictor of transmural bowel necrosis. [5][4]
Elevated serum lactate levels reflect poor tissue perfusion and bowel ischemia, acting as a key marker of severe sepsis or septic shock. [5][4]
Raised procalcitonin concentrations correlate with the extent of intestinal necrotic damage and increased mortality risk. [5][4]
Acute strangulation may present with lower abdominal pain, constipation, and rectal bleeding. [5][4]
The appearance of peritoneal signs (abdominal rigidity, rebound tenderness, guarding) indicates perforation of the strangulated bowel. [3][1]

In hemodynamically unstable patients, surgical intervention must not be delayed for imaging; rapid operative management takes absolute precedence. [3][5]1
For hemodynamically stable patients, contrast‑enhanced CT can be used to identify complications such as obstruction, perforation, or peritonitis, but imaging should never postpone definitive treatment. [7][5]
Immediate surgical treatment is mandatory when signs of shock, gangrene, or perforation are present. 1
An abdominal open approach is the recommended operative technique for unstable patients with complicated rectal prolapse. 1
Non‑operative (conservative) management is contraindicated when strangulation with gangrene or perforation is evident. [3][2]
