PURPOSE: The aim of this study was to compare the transinguinal preperitoneal technique (TIPP) using a memory ring patch versus the Lichtenstein technique in relation to acute and chronic pain, post-operative complications and recurrence rates. METHODS: During an 18-month period, all adult patients that needed treatment for a unilateral inguinal or femoral hernia were treated by the TIPP repair using the Polysoft mesh. This group was retrospectively compared with a historical cohort of patients treated by the Lichtenstein technique. Our policy concerning type of anaesthesia, post-operative pain management and visual analogue scale measurements did not change over the study period. For post-operative pain evaluation, the visual analogue scale was used (0-10) and scores were measured after 6 h, 24 h, 1 week, 1 month, 1 year and yearly thereafter. Recurrence rates were evaluated at time of clinical examinations. RESULTS: In total, 142 patients have been analysed with the TIPP technique (group I) versus 136 patients operated in the previous 2 years with a Lichtenstein repair (group II). In group I, 112 patients (78.9%) received a medium size patch of 14 x 7.5 cm and 30 patients (21.1%) had a large patch (16 x 9 cm). The mean operative time for a TIPP procedure was statistically shorter than for a Lichtenstein repair, 33 versus 44 min, respectively (p = 0.04). After 24 h, 1 week and 1 month post-surgery, there was significantly less post-operative pain observed in the TIPP group than in the Lichtenstein group. In total, four recurrences were observed in the TIPP group (2.8%), of which one laterally and three medially. In group II, seven recurrences were observed in total (5.1%), of which five were detected within 2 years of follow-up (3.7%). CONCLUSION: For surgeons performing the Lichtenstein repair but looking for modifications concerning pain relief and a quicker procedure, the TIPP approach is a feasible alternative that seems to be associated with less post-operative pain.
