Comparative effect of laparoscopic total extraperitoneal repair versus preperitoneal inguinal hernia via middle line incision

Objective To compare the clinical efficacy of total extraperitoneal repair (TEP) and trans-abdominal preperitoneal inguinal hernia repair (TAPP) of the pertoneal cavity in laparoscopy. Methods Between September 2013 and November 2015, one hundred and ten cases of laparoscopic channel xenon repair surgery according to admission order were divided into TEP and TAPP Group, each group of 55 patients, differences of outcome rate, pain level, quality of life, and foreign body sensation between the two groups were compared. Results There was no significant difference in intraoperative time and intraoperative blood loss between the two groups. The incision length of TAPP and the incidence of occult hernia were higher than those of TEP, and the differences were statistically significant (t=1.713, χ2=2.968, P=0.000, 0.000). The duration of postoperative pain between the two groups had no statistical significance, but eating time, ambulation time, and postoperative hospitalization time differences were statistically significant (t=1.635, 2.628, 1.748, P=0.000, 0.000, 0.000). The differences of pain degree VAS score, quality of life and foreign body sensation index in different time points were statistically significant (P<0.05). The incidence of postoperative complications in the TEP group was less than that in TAPP group, and the differences in sensory abnormalities in scrotal emphysis, serum swelling and inguinal region were statistically significant (χ2=5.469, 6.275, 5.080, P=0.000, 0.000, 0.000). Conclusion Both TEP and TAPP are safe and effective in the treatment of inguinal hernia. Key words: Inguinal hernia; Herniorrhaphy; Laparoscopes; Midline incision
