Laparoscopic transperitoneal procedure for routine repair of groin hernia

Background Laparoscopic transperitoneal hernioplasty (TAPP) repair of inguinal hernias is thought to be a difficult surgical technique with high complication rates. The present study evaluated TAPP based on prospective documentation. Methods The primary aim of the study was analysis of the individual learning curve, comparing consultants with trainees. Secondary endpoints included postoperative morbidity, time of disability and rate of recurrence. Results A total of 8050 TAPP repairs have been performed since 1993. By 2001, 99·9 per cent of all hernia repairs were done by TAPP. The median operation time dropped from 50 min in the first 600 cases to 42 min thereafter. The morbidity rate decreased from 9·3 to 2·6 per cent, and the rate of recurrence from 4·8 to 0·4 per cent. Within the same interval the proportion of training procedures increased from 1·7 to 44·9 per cent in 2001. Morbidity and recurrence rates were similar for trainees and consultants. Conclusion TAPP is an effective and safe technique. It can be performed in a standard way for all inguinal and femoral hernias. The present results indicate that TAPP is possible in a routine setting, as well as in the training situation for young surgeons.
