[Tension-free technique for the repair of strangulated abdominal hernias]

There are just few studies regarding the use of tension-free techniques during the emergency operations of strangulated hernias among all the articles on the subject of surgical herniorrhaphy. Assessment of safety of the use of mono- or double-filament polypropylene mesh for the repair of strangulated hernia constituted the aim of the study. There were 81 inguinal and 34 other hernias (mostly incisional) in the group of 115 surgically treated patients with strangulated abdominal wall hernias. During the surgical operation in 84 patients strangulated bowel loop was reduced, 22 patients were treated with reduction of larger omentum, 7 patients required bowel resection (including 2 resections of Meckel diverticulum) and 2 resections of the omentum. All patients received prophylactic dose of broad-spectrum antibiotic during the surgical procedure and for 2-4 days after the operation. There were 15 cases of surgical site complications noted. Only two such cases (purulent infection in two patients and necrosis of wound margins in one) constituted potential threat to the implant. The incidence of local surgical complications was somewhat lower in the group of inguinal hernias as compared to the others (11.1% vs. 17.6%). The data from our study confirm the fact that mono- or double-filament polypropylene mesh can be safely used for the repair of strangulated hernia and the risk of local surgical complications is scant.
