Endoscopic treatment of sessile rectal adenomas: comparison of Nd:YAG laser therapy and injection-assisted piecemeal polypectomy.

This prospective study was carried out in order to compare endoscopic laser therapy with injection-assisted piecemeal polypectomy for treatment of sessile rectal adenomas. We randomized 94 patients with rectal sessile adenomas to either of the two treatments. The adenomas were classified according to size as extensive or intermediate. Of the patients with extensive adenomas, a complete ablation was achieved in 63.6% with laser versus 33.3% with piecemeal snaring (p < .01). For the intermediate adenomas, the rates of permanent ablation were 81.2% with laser versus 86.6% with piecemeal snaring polypectomy (difference not statistically significant). The complication rates were acceptable in both the laser and piecemeal snaring groups. (One case of perforation and one case of stenosis were observed in the laser group, both probably related to prior electroresection.) Our study suggests that the specific indication for laser therapy should be extensive lesions; with intermediate adenomas, laser therapy and injection-assisted piecemeal polypectomy are equally efficacious for achieving complete ablation. However, the duration of initial treatment differs: 6.3 weeks for laser therapy versus 2.4 weeks for piecemeal polypectomy; moreover, about 70% of the intermediate adenomas were eradicated with a single session of piecemeal polypectomy.

A randomized prospective study of endoscopic bipolar electrocoagulation and heater probe treatment of chronic rectal bleeding from radiation telangiectasia.

BACKGROUND: Our purposes were to (1) evaluate efficacy and safety of bipolar or heater probe endoscopic coagulation compared to prior medical therapy for bleeding radiation telangiectasia, and (2) consider the impact of treatments on patients' impression of their overall health and activity. METHODS: Twelve months of medical management had failed in 18 men and 3 women with chronic, recurrent hematochezia and anemia after radiation treatment of pelvic malignancies. Patients had multiple rectal telangiectasias coagulated with bipolar or heater probes in a randomized, prospective study. RESULTS: Rectal bleeding stopped within four treatment sessions. During 12 months of endoscopic versus medical therapy, severe bleeding episodes diminished significantly for bipolar probe versus 12 months of prior medical therapy (75% vs 33%) and heater probe (67% vs 11%); mean hematocrits rose significantly for patients undergoing bipolar (38.2 vs 31.9) and heater probe (37.6 vs 28.4) treatments, and their impression of overall health improved. During long-term follow-up, new telangiectasias or rectal bleeding were easily controlled. No major complications resulted. CONCLUSIONS: (1) Bipolar or heater probes were safe and effective relative to medical therapy for palliation of patients with lower gastrointestinal bleeding from radiation telangiectasias, and (2) all patients improved in ability to travel and exercise and in their overall impression of their health.

New application of endoloop for rectal polypectomy.

The primary difficulty in performing rectal procedures such as polypectomy in children is the limited space in which to suture after a biopsy. Use of an available laparoscopic pretied loop ligature has been adapted to simplify these cases.
