Our experience with totally extraperitoneal technique of laparoscopic inguinal hernia repairs modified by Stolzenburg

Abstract

Two current types of laparoscopic inguinal hernia repair are known: the TransAbdominal PrePeritoneal (TAPP) and the Totally ExtraPeritoneal (TEP) method. The mesh is placed in the preperitoneal space (sublay). Usually during TAPP method we fix the mesh with tacks or staples. In case of TEP fixation it is not necessary because the intraabdominal pressure keeps the implant in position. There is no significant difference between the two methods in terms of recurrence. The advantage of TEP is that the abdominal cavity remains intact, hence reduces the risk of intraabdominal injuries and adhesions. It is unnecessary to use special stapler or tacker. Our team performed 50 TEP procedures in male patients with uni- or bilateral inguinal hernias in the period 2011-2013. We prepared the mesh in a special way according to Stolzenburg and placed it to the subfunicular area. We did not apply additional fixation (tacks, stitches) and drainage. Mean hospital stay was 1 day. We allowed complete physical activity 10-12 days after surgery. No recurrence was observed during the 2 years of follow-up. The mean operating time was 70 minutes. We performed conversion in 3 cases (Lichtenstein 2, TAPP 1). In one case there was an injury of the inferior epigastric artery. In two cases we have detected neuralgia in the postoperative period. After the learning curve the TEP method can be used safely with good functional results. The technique of mesh positioning reduces the risk of complications and provides cost-effectiveness.
