Comparison between TAPP & Lichtenstein techniques for inguinal hernia repair: A retrospective cohort study

Abstract

BackgroundWorldwide, inguinal hernia repair is one of the commonest surgeries. The best treatment option to primary hernia has been investigated, but there still remains lack of evidence about the ideal approach. Therefore, this study aimed to compare the outcomes of inguinal hernia repair using transabdominal preperitoneal procedure (TAPP) & Lichtenstein techniques. Materials and methodsThis was a retrospective cohort study, conducted at Department of General & Minimal Invasive Surgery, SKIMS Medical College, Bemina, Srinagar. For performing the analysis, we used SPSS. Continuous variables were expressed as mean and standard deviation, and the categorical ones were presented as frequencies and percentages. ResultsA total of 60 patients were included (30 in each group). The mean age of the patients in both groups was around 54 years, and all patients were males. In unilateral cases the operating time was greater in the TAPP group than the Lichtenstein group (p < 0.001); however, in the bilateral cases, the operating time was significantly greater in the Lichtenstein than the TAPP group (p = 0.003). The pain scores, in unilateral cases, were significantly lower in the TAPP group than the Lichtenstein group (p < 0.001). The overall complication rate in the TAPP group was 6.7% while in the Lichtenstein group it was at 23.3%. In unilateral and bilateral cases, the patients significantly returned to work earlier in the TAPP group than those in the Lichtenstein group (p < 0.001). ConclusionTAPP and Lichtenstein techniques are both safe and reliable techniques for inguinal hernia repair. However, TAPP repair showed lesser post-operative pain, earlier discharge from the hospital, earlier return to usual activities, better cosmetic outcomes, and less persisting pain. However, there was no significant difference in the complication rate and TAPP repair was more costly for the patient.
