Laparoscopic appendectomy, stump closure and endoloops: A meta-analysis.

ABSTRACT

BACKGROUND: Acute appendicitis (AA) is one of the main indications for urgent surgery. Laparoscopic appendectomy (LA) has shown advantages in terms of clinical results and cost-effectiveness, even if there is still controversy about different devices to utilize, especially with regards to the endoloop (EL) vs endostapler (ES) when it comes to stump closure. AIM: To compare safety and cost-effectiveness of EL vs ES. METHODS: From a prospectively maintained database, data of 996 consecutive patients treated by LA with a 3 years-follow up in the department of Emergency General Surgery - St Orsola University Hospital, Bologna (Italy) were retrieved. A meta-analysis was performed in terms of surgical complications, in comparison to the international literature published from 1995 to 2021. RESULTS: The meta-analysis showed no evidence regarding wound infections, abdominal abscesses, and total post-operative complications, in terms of superiority of a surgical technique for the stump closure in LA. CONCLUSION: Even when AA is complicated, the routine use of EL is safe in most patients.
