Summary INTRODUCTION:Aluminum potassium sulfate and tannic acid (ALTA) sclerotherapy is increasingly popular for treating internal hemorrhoids. This injectable compound incites inflammation to dampen hemorrhoidal blood flow and inflict secondary fibrosis. Herein, we detail the implications of ALTA treatment for laparoscopic low anterior resection of rectal cancer.PATIENT PRESENTATION:A 72-year-old man receiving ALTA sclerotherapy for internal hemorrhoids thereafter required laparoscopic low anterior resection for newly discovered early rectal cancer. Observed changes of anal canal resembled those of radiochemotherapy and proved problematic. There was mural thickening and sclerosis at the planned resection site. To ensure proper removal, the bowel was compressed and stapled slowly. A two-shot resection took place (without straining), anastomosis was performed, and a covering stoma was constructed. Recovery was uneventful, allowing discharge on postoperative Day 10. The ileostomy was closed at a later time.DISCUSSION:Although little information is available on long-term rectal pathology after ALTA therapy, existing data suggest that sclerosis persists well beyond injection timeframes. Hence, caution is required in dissecting and debriding sclerotic remnants. We have identified only four earlier reports in this setting, the present case providing added perspective.CONCLUSION:Colonoscopy is highly advisable prior to ALTA therapy. A thorough work-up before rectal surgery is also essential, documenting any past treatments for anorectal disease, especially ALTA.
