Info

A dilated appendix with a maximum diameter of 8 mm shows a fluid-filled lumen and thick enhanced walls with a small appendicolith noted at its base. The appendix tip, reaching the upper pre-rectal region with areas of loss of wall integrity associated with early formation of fluid collection, measures roughly 36 x 28 mm, extending to the Douglas pouch. 

The diagnosis was made as acute pelvic appendicitis with a high suspicion of perforation complicated by abscess formation.

Otherwise, normal.

Operative notes:

Incision:

Right grid iron incision.

Findings:

A perforated pelvic appendix with a small amount of thick pus in the pelvis.

Procedure:

  • the appendix was separated from its adhesions

  • the mesoappendix was ligated and cut

  • the appendix was transfixed at the base and cut

  • a pus swab was taken, and lavage was done

  • a medium drain was kept as a large drain was not available

Case Discussion

Appendicular abscess is considered the most prevalent consequence of acute appendicitis, especially on the fifth to tenth day after a perforated appendix.

I would like to thank Dr. Aftab Hussain, SQH Pediatrics Surgery Department, for his valuable operative notes.
