Stand der laparoskopischen Leberchirurgie. Ergebnisse einer Umfrage der DGAV-Mitglieder

Background: To date laparoscopic hepatic surgery is only common in a few centres for a specific selected patient group. The intention of this survey was to estimate the current state of affairs for laparoscopic hepatic surgery in Germany at 2008. Materials and Methods: A questionnaire was prepared and sent out by e-mail in May 2009 to the members of the DGAV (German Society of General and Visceral Surgery). The feedback was evaluated anonymously. Results: A total of 181 answers were received by 31st July 2009 (return rate of 15.9%). The return rate of basic and standard care hospitals was 9.2%, specialized hospitals 23.6%, hospitals with maximum care 50% and university hospitals had a return rate of 71.9%. The question whether laparoscopic hepatic surgery had been performed in 2008 was answered with YES by 125 (69.1%) and NO by 54 (29.8%) members. The number of laparoscopic hepatic surgery interventions (laparoscopic ultrasound, laparoscopic radiofrequency ablation and resection) in 2008 was given as more than 50 by 4 (2.2%) hospitals, between 20 and 50 by 11 (6.1%) hospitals, between 10 and 20 by 23 (12.7%) hospitals, between 5 and 10 by 45 (24.9%) hospitals and between 0 and 5 by 54 (29.8%) hospitals. In 2008 the frequency of laparoscopic ultrasound during intraoperative staging to confirm the diagnosis ranged from 2 to 250, whereby 96.4% of the hospitals had less than 50 and only 2 hospitals (2.7%) had 211 and 250 examinations, respectively. 50 hospitals carried out laparoscopic radiofrequency ablation (RFA). 69 (38.1%) of the interviewed hospitals reported hepatic laparoscopic resections (n=551). Conclusion: Laparoscopic liver surgery has been done in Germany in patients with benign or malignant liver lesions. Pure laparoscopy is the most common access. Atypical resections are the primarily indication followed by left lateral resections. All further types of resection have been done in a very small number. Laparoscopic liver surgery has been performed in all types of hospitals.
