Purpose: A laparoscopic approach for emergency appendectomy is increasingly used, in pediatric patients as well. The objective of this study is to audit the current state of diagnostic work-up, surgical techniques and its outcome in children with acute appendicitis., Methods: A prospective consecutive observational cohort study was carried out in a 2-month study period. All patients under 18 years that were operated for suspected acute appendicitis were included. Primary outcome was the infectious complication rate after open and laparoscopic approach; secondary outcomes were preoperative use of imaging and post-operative predictive value of imaging, normal appendix rate and children with a postoperative ileus., Results: A total of 541 children were operated for suspected acute appendicitis in 62 Dutch hospitals. Preoperative imaging was used in 98.9% of children. The normal appendix rate was 3.1%. In 523 children an appendectomy was performed. Laparoscopy was used in 61% of the patients and conversion rate was 1.7%. Complicated appendicitis was diagnosed in 29.4% of children. Overall 30-day complication rate was 11.9% and similar after open and laparoscopic. No difference was found in superficial surgical site infections, nor in intra-abdominal abscesses between the open and laparoscopic approach. Complicated appendicitis is an independent risk factor for infectious complications., Conclusion: The laparoscopic approach is most frequently used, except for young children. Superficial surgical site infections are more frequent after open surgery only in patients with complicated appendicitis. The normal appendix rate is low, most likely because of routine preoperative imaging.

Non-surgical treatment of acute phlegmonous appendicitis has been receiving increasing attention in recent years, representing a reversal of policy. The appendectomy came into vogue at the beginning of the 20th century. It is true that prompt surgical intervention in all patients with appendicitis or an indication thereof almost guarantees success, but it gradually came to be forgotten that this intervention was not always necessary. In this article we will document the historical development of this disease and its treatment, and return to the original reports made by pathologist Reginald Fitz and the internist William Osler to show that their opinion was not black and white. Many surgeons in the Netherlands were also initially more restrained. In the course of time recognition of the natural progression of the disease vanished, until new developments placed this more sharply in the limelight.

Purpose: Although a national guideline has been implemented, the optimal approach for appendectomy in children remains subject of debate in the Netherlands. Opponents of laparoscopy raise their concerns regarding its use in complex appendicitis as it is reported to be associated with an increased incidence of intra-abdominal abscesses. The aim of this study was to evaluate the outcome of surgical approaches in both simple and complex appendicitis in paediatric patients., Methods: A 10-year retrospective cohort study was performed (2001-2010) in paediatric patients treated for suspected acute appendicitis. Patients were divided into either simple or complex appendicitis and into different age groups. Primary outcome parameters were complication rate (intra-abdominal abscess (IAA), superficial surgical site infection (SSI) and readmission) and hospital stay., Results: In total, 878 patients have been treated (median age 12, range 0-17 years). Two-thirds of the patients younger than 6 years had complex appendicitis, compared to one quarter in the group aged 13-18. In the complex appendicitis group, LA was associated with more IAA and early readmissions. In the simple appendicitis group, the complication rate was comparable between the two approaches. Significantly more IAAs were seen after LA in the youngest age group., Conclusion: This study demonstrates the unfavourable outcome of LA in the youngest age group and in patients with complex appendicitis. Therefore, we advise to treat these patients with an open approach.
