Diagnostic value of laparoscopic inguinal allohernioplasty in detection of occult hernias of inguinal region

Abstract

Aim. To evaluate diagnostic value of laparoscopic inguinal allohernioplasty in identification of occult forms of hernias of the inguinal region.

Materials and Methods. The study was conducted on the basis of the results of surgical treatment of patients with inguinal hernias on the base of the Department of Hospital Surgery of RyazSMU in Ryazan State Emergency Care Hospital and on the base of the Department of Surgery, Obstetrics and Gynecology of Additional Postgraduate Education Faculty in Ryazan Regional Clinical Hospital, from 2015 to 2020 (n=207). Operations were performed with the absence of contraindications to narcosis and carboxyperitoneum, and if patients desired to be operated on by the proposed method. In all the patients included into the study, hernioplasty was performed using laparoscopic approach, with preperitoneal placement of the endoprosthetic mesh. For purity of the experiment, only polypropylene meshes were used. Standard meshes from monofilament polypropylene were used with surface density 65-80 g/m² and volumetric porosity 80-85%. Meshes 15x15 cm dimension were used with cut angle with 7.5A cm catheti.

Results. Of 207 patients, 28 were operated on for bilateral inguinal hernias. Only in one of them hernia was diagnosed in the preoperative stage. In the rest 27 patients, an occult hernia was found opposite to the previously diagnosed side. In 17 patients, besides hernias diagnosed in the preoperative and intraoperative stages, occult hernias were detected in the process of dissection of the preperitoneal space.

Conclusion. Laparoscopic inguinal allohernioplasty permits to diagnose occult hernias that were not detected in the preoperative examination: femoral, obturator, inguinal hernias on the contralateral and/or unilateral side. This permits to perform hernioplasty taking into account the intraoperative finding, in one surgical procedure without subjecting the patient to repeated hospitalization, narcosis and operation.
