Influence of the learning process on safety and effectiveness of laparoscopic fundoplication

The introduction of laparoscopic techniques into surgical practice has required a learning process on the part of the surgeons involved. The duration, morbidity, and functional outcome of laparoscopic fundoplication were evaluated in our institution's first 146 cases. During a 34-month period the patients underwent laparoscopic Nissen (n = 102) or Toupet (n = 44) fundoplication. Conversion to open access was necessary in 7 cases, re-operation for complications in 2, all among the first 40 cases of the series. The median operating time was 165 min (range 75-375) in the first 40 cases, and 105 min (range 50-235) thereafter (P < 0.001). Body mass index, grade of esophagitis, and the surgeon's experience were independent predictors of the operating time. One hundred and thirty-four patients (92 %) could be evaluated for recurrence of reflux, which was encountered in 2 (5 %) of the first 40 cases and 8 (8 %) of 94 patients in the later group.
