This study compares the results of two laparoscopic hernioplasties: the transabdominal preperitoneal (TAPP) and the totally extraperitoneal (TEP). Over a 43-month period 1,115 laparoscopic hernioplasties, 733 TAPP and 382 TEP, were performed in 866 patients. There were 11 major complications in the TAPP group (2 recurrences, 6 trocar hernias, 1 small-bowel obstruction, 1 trocar, and 1 dissection injury of the small bowel) compared to 1 recurrence and no intraperitoneal complications in the TEP group. Five TEP procedures required conversion to the TAPP approach, resulting in one umbilical hernia. The median time to return to work did not vary with the approach, but was prolonged in patients compensated for time off, 16 vs 8 days for noncompensated patients. Results suggested that both techniques shortened recovery and eliminated most early failures, but the totally extraperitoneal approach reduced the potential for intraperitoneal complications and may be the procedure of choice in most situations.

The purpose of this study was to evaluate the results of a laparoscopic approach to recurrent inguinal hernia repair which dissected the entire inguinal floor and repaired all potential areas of recurrence without producing tension. Both a transabdominal preperitoneal and a totally extraperitoneal laparoscopic approach were utilized. Ninety recurrent hernias were repaired in 81 patients. The patients had 26 indirect, 36 direct, and 26 pantaloon recurrent hernias of which eight had a femoral component. In all but one patient the primary operations were open anterior repairs. The median follow-up was 14 months, ranging from 1 to 28 months. Patients returned to normal activities in an average of 1 week. The only recurrence observed was in the one patient whose primary repair was laparoscopic. When the entire inguinal floor of the recurrent hernia was redissected and buttressed with mesh, early recurrence was eliminated and recovery was shortened.

To determine if laparoscopic inguinal herniorrhaphy can be performed safely in unselected patients, the authors' first 100 consecutive laparoscopic inguinal hernia repairs were reviewed. All patients with inguinal hernias who were candidates for general anesthetic were accepted for the study. Their ages ranged from 18 to 84 years. One hundred and six hernias were laparoscopically repaired in 95 males and 4 females. One male patient required an open hernia repair. The first 14 patients were repaired with a preperitoneal patch and plug technique, and the next 85 with the double-buttress transabdominal preperitoneal approach. Two pieces of polypropylene mesh were stapled to the transversalis fascia, ileopubic tract, and Cooper's ligament after the preperitoneal dissection of the hernia was completed. The first piece was placed over the indirect space, with a slit for the cord medially, and the second piece was placed over the entire direct and indirect area. Patients have been followed from 8-18 months. To date, no recurrence has developed. Complications have included seroma, inferior epigastric bleeding, trocar hernia, and neuralgia. Patients have returned to work and normal activity in 2 days to 2 weeks, with an average of 1 week.
