Complications and conversions of pediatric videosurgery: the Italian multicentric experience on 1689 procedures.

BACKGROUND: The aim of this study was to evaluate the incidence and management of complications of videosurgical procedures that occurred during a 4-year period in eight Italian pediatric surgery centers. METHODS: Between 1996 and 1999, 2305 videosurgical procedures were performed in 11 centers of pediatric surgery. The data from 3 centers, for a total of 616 procedures, were largely incomplete and were thus excluded from the study. We analyzed the data from 8 centers only, for a total of 1689 laparoscopic or thoracoscopic operations on patients aged between 15 days and 16 years. The type of operations performed ranged from basic videosurgical interventions, such as varicocelectomy and cryptorchidism, to advanced laparoscopic procedures, such as splenectomy, total colectomy, and esophageal achalasia. Each patient's file was examined for any complications that may have occurred during the surgical procedure and for a record of how these were managed. RESULTS: We recorded 79 complications (4.6%) in our series. In 57 cases (72.2%) the problem was solved by videosurgery. Twenty-two cases (27.8%) required conversion to open surgery. There was no mortality in our series. At a maximum follow-up of 4 years, all children were alive and had no problems related to the videosurgical complications. CONCLUSIONS: We believe that the routine use of open laparoscopy in pediatric patients is a key factor to avoiding complications related to the Veress needle and blind introduction of the first trocar. Moreover, the surgeon's laparoscopic experience, the correct indications for laparoscopic surgery, and the verification of the laparoscopic equipment before surgery are also important rules to follow to reduce the incidence of complications. In the beginning, it is preferable to have the assistance of an expert laparoscopic surgeon to decrease the complications related to the learning curve period.

Laparoscopic treatment of pediatric varicocele: a multicenter study of the italian society of video surgery in infancy.

PURPOSE: We report preliminary results of a multicenter study of the Italian Society of Video Surgery in Infancy on the laparoscopic treatment of pediatric varicocele. MATERIALS AND METHODS: A total of 161 children 6 to 16 years old (median age 12.5) underwent laparoscopic treatment of varicocele at 6 pediatric surgery divisions. Varicocele was on the left side in 159 cases (98.7%) and bilateral in 2 (1.3%). Two boys had recurrent left varicocele. All children were treated with laparoscopy, including ligation of the spermatic veins only in 28 (17.3%), and ligation of the testicular veins and artery in 133 (82.7%). In 10 boys (6.2%) an additional procedure was done simultaneously, including closure of an apparently patent peritoneal vaginal duct on the right side in 7 and resection of epiploic adhesions between the intestinal loops and abdominal wall from previous appendectomy in the remaining 3. RESULTS: Average operative time was 30 minutes and hospitalization was about 24 hours. At followup there were 13 minor complications (8%), including left hydrocele in 9 children who underwent the Palomo technique, minor scrotal emphysema in 2 and umbilical granuloma in 2. In our series varicocele recurred in 1 boy (3.5%) who underwent ligation of the spermatic veins only and in 3 (2.2%) treated with the Palomo technique. CONCLUSIONS: Our preliminary experience shows that the results of the laparoscopic approach are comparable to those of the open approach. However, the important advantages of laparoscopy over the open approach are its minimal invasiveness and precision of intervention. Moreover, laparoscopy allows treatment of other intra-abdominal pathological conditions using the same anesthesia, as in 10 patients in our series. We believe that ligating the testicular veins and artery is preferable to ligating the testicular veins only, even if the incidence of hydrocele is not negligible after the Palomo procedure.
