    Acute appendicitis is a leading cause of emergency surgery, with laparoscopic appendectomy being the gold standard for uncomplicated cases.

  • 2

    The use of prophylactic abdominal drainage in laparoscopic appendectomy for perforated appendicitis remains controversial due to mixed evidence.

  • 3

    The DLAP study involved 21 institutions in Japan and aimed to evaluate the association of abdominal drainage with postoperative intra-abdominal abscess formation.

  • 4

    Data for the study were collected retrospectively, focusing on comprehensive clinical and intraoperative information from participating hospitals.

  • 5

    The primary endpoint of the study was the formation of intra-abdominal abscesses within 30 days postoperatively.
