Duodenal obstruction due to appendicular abscess (a case report).

Area of Science:

• Gastroenterology
• Surgical Pathology

Background:

• Appendicular abscesses are typically localized infections.
• Uncommon presentations of appendicitis can lead to unexpected complications.

Observation:

• A case of duodenal obstruction caused by an appendicular abscess is presented.
• The abscess, originating from the appendix, tracked retroperitoneally behind the mesocolon.
• This retroperitoneal tracking led to extrinsic compression and obstruction of the third part of the duodenum.

Findings:

• The appendicular abscess was successfully treated by surgical drainage.
• An anterior gastrojejunostomy was performed to bypass the obstructed duodenal segment.
• This surgical approach relieved the duodenal obstruction.

Implications:

• This case highlights a rare but serious complication of appendicitis.
• It underscores the importance of considering atypical presentations and potential retroperitoneal involvement in appendicular abscess.
• Effective management involves addressing the abscess source and relieving the obstruction, as demonstrated by the successful surgical outcome.
