A Complete Common Mesentery Presenting With Appendicular Peritonitis : Case report

Case Report

Abstract

Intestinal malrotation is an uncommon anomaly resulting from an interruption in the rotation and fixation of the embryonic gut. It can remain asymptomatic if the rotation halts at 90 degrees, leading to atypical presentations such as appendicitis, as observed in our case, or pose serious risks when accompanied by incomplete common mesentery and compounded by small intestine volvulus. A 58-year-old male presented with abdominal pain four days prior to admission, accompanied by fever. Clinical examination revealed abdominal tenderness, and laboratory tests indicated an inflammatory response. A CT scan confirmed acute appendicitis associated with complete common mesentery, prompting the patient to undergo open laparotomy appendectomy. Despite acute appendicitis typically presenting in a conventional manner, diagnosing its atypical forms in the context of intestinal malrotation poses considerable challenges. Abdominopelvic CT scan plays a crucial role in diagnosis, and laparoscopic appendectomy is the preferred treatment approach.
