Treatment of solitary rectal ulcer are A/E:a) Laxativesb) Rectopexyc) Bandingd) Sclerosant injectione) Enema

**Core Concept**
Solitary rectal ulcer (SRU) is a chronic condition arising from mucosal trauma due to chronic straining, often in patients with constipation. It is typically managed conservatively, with treatments aimed at relieving symptoms and promoting healing through bowel habit modification and local interventions.

**Why the Correct Answer is Right**
Laxatives (a) are used to relieve constipation and reduce straining, which is a key factor in SRU pathogenesis. Sclerosant injection (d) is a local treatment that induces fibrosis and promotes healing of the ulcer by causing vascular obstruction. Banding (c) may be used in some cases to reduce rectal distension and improve symptoms. However, rectopexy (b) is not a standard treatment for SRU; it is used for rectal prolapse, not solitary ulcer. Enema (e) is generally not recommended as it may irritate the ulcer and worsen symptoms. Thus, the correct options are laxatives (a) and sclerosant injection (d), making **cd** the correct pair.

**Why Each Wrong Option is Incorrect**
Option A: "cd" is correct — includes laxatives and sclerosant injection, both evidence-based for SRU.
Option B: "bc" includes rectopexy (b), which is inappropriate and not used in SRU.
Option C: "bd" includes rectopexy (b), which is incorrect and not indicated.
Option D: "ac" includes enema (e), which is contraindicated due to ulcer irritation.

**Clinical Pearl / High-Yield Fact**
In SRU, avoid enemas and avoid surgical procedures like rectopexy — these can worsen symptoms. First-line therapy is bowel regimen with laxatives and local injections like sclerosants.
