Appendicitis is an acute disease requiring urgent surgical treatment. Acute appendicitis is the most common surgical emergency in children and young adults, with an incidence of about 100-140 cases per 100,000 people. In our study we analyse 501 consecutive appendectomies performed in our department. From June 2003 to December 2008 we performed 501 appendectomies, 287 in male and 214 in female patients. The average age was 27.99 years (range: from 4 to 94 years). We routinely perform a laparoscopic approach with a standard protocol for patient selection. Following a standard protocol, 429 patients were selected for the laparoscopic approach and 72 for an open appendectomy. In 411 patients (95.8%) the surgical procedure was completed in laparoscopy with a conversion rate of about 4.2% (18/429). The conversion rate in the simple appendectomy subgroup was 0.98%, as against about 12.1% in the complex appendectomy subgroup. The open appendectomy group comprised 72 patients, 27 patients treated with an open approach by choice, 26 for necessity and 19 for protocol violation. There were 9 post-appendectomy complications (2.1%) and 3 re-operations (0.5%); the mortality rate was nil. Although 20 years have passed since the first laparoscopic appendectomy, today it is still debated whether or not the laparoscopic approach is the correct surgical procedure for the treatment of acute appendicitis. Several studies have shown that laparoscopic appendectomy presents a number of advantages in terms of a shorter hospital stay, less postoperative pain and fewer wound infections. Some authors, however, have demonstrated that the laparoscopic approach for acute appendicitis is associated with increased operative times and risk of intra-abdominal abscesses (above all if the appendix is perforated). Our experience confirms that the routinely performed laparoscopic approach to treat acute appendicitis is associated with a low rate of abscess complications: in our series some of the complications could be attributed to the surgical learning curve.
