Objective To investigate the clinical efficacy of transabdominal preperitoneal laparoscopic hernia repair (TAPP). Methods Three trocars were introduced into the abdomen at the umbilicus and both sides 10 cm from the umbilicus, respectively. The parietal peritoneum was opened at 5 cm above the internal ring and near the external border of the umbilicus. The hernial sac was dissected and a patch overlying the defect was stapled with the pectineal ligament and the conjoined tendon. Results The laparoscopic operation was completed successfully in all the 50 cases. The operation time was 20~70 min (39.8?10.5 min). Postoperatively, there were 1 case of groin pain and 2 cases of urine retention. The duration of postoperative hospital stay was 1~4 days (mean, 2 days). Follow-up observations in the 50 cases for 1~11 months (mean, 7 months) found no recurrence. Conclusions Transabdominal preperitoneal laparoscopic hernia repair is a safe and effective tension-free hernioplasty.
