Transanal repair of rectocele with high frequency radio scalpel

Aim: This is a prospective randomized study to analyze results obtained in two groups of patients, affected by stage 2 rectocele and treated with rectum anterior wall repair and strength, performed with standard or modified Khubchandani technique, using High Frequency (HF) Radio Scalpel. Materials and methods: A cohort of 24 patients with stage 2 rectocele (Mellgren's classification) have been included. Twelve (group A) underwent surgery with standard technique and twelve (group B) underwent surgery using the HF Radio Scalpel, which cuts and coagulates tissues without damage thanks to its low working temperature (45-70°C). Each patient underwent proctolo-gical examination and anoscopy in 7th, 15th, 45th POD and after 6 and 12 months. Results: During post-operative follow-up 5 patients from group A and 1 from group B didn't show up so that they drop out the study. As a result, group A is composed by 7 patients and group B by 11 patients. Mean operating time was significantly favourable in group B (51 vs 33 minutes, p< 0.01). The differences between other parameters weren't statistically significant, even if post-operative course was less difficult in HF Radio Scalpel group. Conclusions: The surgical technique to repair and reinforce anterior rectal wall is easier and faster if performed with HF Radio Scalpel respect to the standard procedure described by Khubchandani. Post-operative course was less painful and, even more importantly considering the patient age, surgical time was shorter. Therefore, the results obtained cast positive light on using this technique to treat uncomplicated grade 2 rectocele
