TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['We report a multicentric prospective study which aimed to evaluate Doppler-assisted ligation of the terminal haemorrhoidal arteries (THD) for II and III degree haemorrhoids.', 'A total of 112 patients from five colorectal units, including 81 men, mean age 48 +/- 13 years, with II degree (39) and III degree (73) haemorrhoids were treated by Doppler-guided transanal de-arterialization and anopexy using a new device (THD).', 'The mean operative time was 33.9 +/- 8.8 minutes, and the mean number of ligatures applied was 7.2 +/- 1.5. Postoperatively, 72% of patients did not need analgesics and the other 28% used nonsteroidal antiinflammatory drugs 1-3 times/day for less than 2 days. All the patients were operated as a day case. Early postoperative complications included haemorrhoidal thrombosis (2 patients), bleeding (1) treated by haemostatic suture, dysuria (6) and acute urinary retention (1). After a mean follow-up of 15.6 +/- 6.5 months (range 6-32), 2/105 (20.9%) patients complained of minor bleeding, while mild pain was still present in 4/51 patients (7.8%). There were no statistically significant differences in the sample population regarding the gender or stage of the disease. Tenesmus was cured in 15/17 patients, dyschaezia in 20/22 patients and mucous soiling in 10/10 patients. No new cases of altered defaecation or faecal incontinence were recorded. Overall, 85.7% of patients were cured and 7.1% improved. Residual haemorrhoids were treated by elastic band ligation in nine (8%) patients and by surgical excision in further five patients (4.5%).'] Is transanal haemorrhoidal artery echodoppler ligation and anopexy ( THD ) effective for II and III degree haemorrhoids : a prospective multicentric study?
