A meta-analysis comparing the laparoscopic transabdominal preperitoneal approach versus the Lichtenstein-type repair was performed. Randomized clinical trials were taken into account, using the PRISMA methodology for the inclusion and exclusion of the filtered studies, the data of the selected studies were grouped in Forest Plot diagrams. Thirteen randomized controlled clinical trials (11 groups of patients) were found which compared LT against TAPP in inguinal hernioplasty, a total of 1,172 patients. Regarding the surgical time, the TL group is favored (95% CI, 9.67-34.03, p < 0.00001). There is no significant difference in the type of hospital stay. In the case of infection, there were nine more cases in the LT group (95% CI, OR 0.26, [0.07, 0.99], p = 0.05). There was no significant difference in the presentation of hematoma in both groups. Chronic pain significantly favored the TAPP group (95% CI, OR 0.32 [0.13, 0.82], p = 0.02). Regarding the recurrence of inguinal hernia there was no significant difference between the groups. Acute postoperative pain favored the TAPP group in the first 12 and 24 hours, on the later hours there was no statistically significant difference. The surgery duration time was significantly shorter in the open group. Laparoscopic approach resulted with lesser complications in regards to infection and chronic pain.
