Three methods of episiotomy repair were randomly assigned after 900 consecutive deliveries. The three procedures were: (1) continuous No. 00-plain catgut in the vagina; No. 00-plain catgut interrupted stiches in the perineal muscles and fascia, and No. 00-nylon interrupted stiches in the skin. (2) The same technique as in (l), but with No. 0-polyglycolic acid (Dexon) in all layers. (3) The suture material as in (2), but used with a subcuticular technique. The women treated with method 3 reported statistically significant less pain and disabilities in the early puerperium. Three months after delivery 262 women (33%) still had perineal complaints which could be directly related to the episiotomy in 25% (8% of total number). The group treated with method 3 had the best long-term results and we conclude that the subcuticular technique using polyglycolic acid should be the method of choice.in all layers, one single needle-mounted suture is sufficient for the entire episiotomy and the suture does not need to 'be removed. This method gave the best results in the early puerperium and also in the long term. This method is now the standard procedure in our department and we regard it as the method of choice for episiotomy repair.
In a randomized study, 204 patients were allocated to either laser or cryo treatment for cervical intra-epithelial neoplasia (CIN). The patients were treated on an outpatient basis without anesthesia unless other conditions requiring anesthesia had to be dealt with at the same time. Both the laser and the cryo method were highly acceptable to the patients. Slightly more patients experienced moderate or severe pain during laser treatment, compared with cryo treatment (P = 0.05). Peroperative hemorrhage did not exceed 25 cc except for one laser-treated patient. Postoperative vaginal discharge was more often seen after cryo coagulation, the discharge being malodorous in 36% of cryo-treated patients and in 17% of laser-treated patients. Pelvic inflammatory disease was found in one patient in each treatment group. Postoperative spotting occurred more often in laser-treated patients (49%) than in cryo-treated patients (22%). At follow-up colposcopy 3 months after treatment, the squamocolumnar junction was fully visible significantly more often in laser-treated patients (P less than 0.001). The cure rates after one laser or cryo treatment were 90% and 91%, respectively. Subsequent to 19 initial treatment failures, 8 patients have at present been retreated with the same method as initially used, and all 8 are cured. The cure rates after one or two treatments are 96% in the laser group and 93% in the cryo group. The rates are preliminary, due to the short observation time. Publications will appear when all patients have been followed for 2 and 5 years.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
