Current status of laparoscopic appendectomy in children: a nation wide survey in Germany

Management of appendicitis in children has changed remarkably over the last decade. The proven benefits of laparoscopic appendectomy (LA) over the open operation have made LA increasingly popular for pediatric patients. To date, no national clinical practice guideline is available for pediatric LA in Germany and the operation is not standardized. Thus, the aim of our study was to evaluate the current status of pediatric LA in Germany.

An internet-based survey was conducted on pediatric LA among all 98 registered pediatric surgical units in Germany, comprising 22 questions with regard to utilization and subjective appraisal of LA, technical standards, perioperative treatment, and training aspects.

The survey was completed by 71 of the 98 units (72%). Technical infrastructure for LA was provided in all units, but only in 79% of the units was LA, the standard approach for appendectomy. Overall quality of LA was rated better compared with open appendectomy by 52% units, equivalent by 38% and worse by 3%. The three-port technique was used by 90% of the units; 10% used a single-port approach. Dissection of the mesoappendix was done with bipolar coagulation in 55%, monopolar coagulation in 24%, harmonic knife in 6%, and endostaplers in 11% of the units. Closure of the appendiceal stump was performed using endoloops in 57%, ligations in 3%, endostaplers in 39%, and harmonic knife in 1%. Removal of the appendix was done through the port by 79%, using a retrieval bag by 18%, whereas in 3% it was removed directly through laparotomy. In case of appendiceal perforation, an intra-abdominal drain was placed in 65%. Perioperative antibiotic treatment for nonperforated appendicitis was given as a single shot in 33% of the units, for 24 hours in 17%, for 3 days in 39%, and for 5 to 7 days in 11%. LA was performed by a trainee under supervision in 87%, by a board approved pediatric surgeon in 2%, by an attending pediatric surgeon in 7%, and by the surgeon-in-chief in 4% of the units. For 93% of the sample, LA was an essential part of pediatric surgical training.

LA is the favored surgical method for pediatric appendectomy in Germany. However, technical details, perioperative therapy and implementation into training programs remain inconsistent. An effort has to be made to establish national clinical practice guidelines to achieve standardization of LA.
