Acute appendicitis (AA) is one of the most common causes of acute abdominal pain seen in emergency departments and appendectomy has been the preferred treatment of this disease for decades. Postoperative intra-abdominal abscess (PIAA) complicates 3% to 25% of appendectomies and the risk is highest following complicated appendicitis. However, the risk for intra-abdominal abscess formation after appendectomy is still a matter of debate. To evaluate PIAA formation after open appendectomy (OA) and laparoscopic appendectomy (LA), in particular in complicated appendicitis. From January 2003 to December 2018, records of patients who underwent appendectomy with diagnosis of appendicitis were retrieved from a computer database for analysis. During the study period, 1809 appendectomies were performed in our institution (939 LAs and 850 OAs). Twenty conversion cases were recorded. There was no difference between the incidences of PIAA (LA, 3.73% (35/939) and OA, 3.41% (29/850); p > 0.05). The incidence of PIAA in those with complicated appendicitis was: LA, 11/212 (5.19%) vs. OA 14/198 (7.07%); p > 0.05. This retrospective study shows that the technique of appendectomy does not appear to affect the incidence of IAAs either in uncomplicated or in complicated appendicitis. However, laparoscopic appendectomy has the advantages of laparoscopic procedures, such as lower hospital stay and earlier return to activities, and should therefore be preferred for acute appendicitis.
