Background/purpose: Laparoscopic techniques and instruments are evolving to lessen the invasiveness of this surgical approach. The authors present their experience with the videosurgical approach using only 1 trocar.
Methods: Between October 1997 and January 2000 the authors performed 59 videosurgical procedures using a 1-trocar approach (mean age, 11.5 years; range, 4 to 18 years). A 10-mm Hasson trocar was inserted in an "open" fashion either through the umbilicus (laparoscopy) or below the apex of the 12th rib (retroperitoneoscopy). An operative laparoscope was used in all cases. The operations were 18 retroperitoneoscopic Palomo varicocelectomies, 1 retroperitoneoscopic renal biopsy, 38 appendectomies, and 2 ileal resections (Meckel's diverticulum, duplication cyst). For appendectomies and ileal resections, the corresponding intestinal loop was grasped and exteriorized through the umbilicus to perform conventional surgery.
Results: Mean operating time was 50.9 minutes (range, 30 to 120) for laparoscopies and 44 minutes (range, 15 to 80) for retroperitoneoscopy. There were 11 conversions (8 appendectomies, 3 varicocelectomies) and no postoperative complications.
Conclusions: "One-trocar surgery" is safe, effective, and fast with a low complication rate and excellent cosmetic results. The authors believe it is the least invasive as well as the most effective approach in the treatment of varicocele, appendicitis, and selected intestinal diseases.
