Outcome and cost comparison of laparoscopic transabdominal preperitoneal hernia repair versus open lichtenstein technique

Laparoscopic hernia repair has all the advantages of a tension free repair. This study compares the laparoscopic transabdominal preperitoneal (TAPP) approach with tension-free open hernia repair in terms of operative time, postoperative pain, hospital stay, complications, and cost. Open and TAPP repairs using polypropylene mesh were performed in two groups of 25 male patients. The difference in operative times between the groups was not significant. Mean pain scores (0-100) for the open group were 54.12 +/- 13.06 at 12 hours and 37.24 +/- 11.38 at 24 hours, significantly higher than the corresponding scores of 38.36 +/- 8.21 at 12 hours and 20.92 +/- 8.73 at 24 hours for the TAPP group (P < 0.05). The mean postoperative analgesic dose was 6.72 +/- 2.72 in the TAPP group, which was insignificantly lower than 7.52 +/- 2.00 in the open group. Mean hospital stay was 2.24 +/- 0.97 days in the open group and 1.52 +/- 0.51 in the TAPP group, which was significant (P < 0.05). Twenty patients (80%) in the TAPP group rated themselves highly satisfied with the surgery as compared to 11 patients (44%) in the open group (P < 0.05). There was no recurrence in either group during a mean followup period of 13.5 months (range, 8-28 months). Laparoscopic hernia repair was significantly more expensive than open ($1100 versus $629). TAPP repair is superior to open repair in terms of shorter hospital stay, lower postoperative pain, and better patient satisfaction. It is also safe, with no recurrence in a short-term period. This technique will be the operation of choice for the treatment of groin hernia after long-term results have been established in our center.
