[Intestinal malrotations in the adult]

Area of Science:

• Gastroenterology
• Surgical Anatomy
• Embryology

Background:

• Intestinal malrotation is a congenital anomaly typically diagnosed in infancy.
• Adult presentation of intestinal malrotation is rare and often associated with complications like appendicitis.

Observation:

• A unique case of adult intestinal malrotation is presented, featuring an anomalous left hypochondrium location of the cecum and appendix.
• The patient presented with peritonitis secondary to acute appendicitis, necessitating an explorative laparotomy.

Findings:

• The anomaly was embryologically classified as a union defect during the third developmental stage of the umbilical loop.
• This case highlights the importance of detailed embryological knowledge of intestinal rotation for surgical accuracy.

Implications:

• Accurate knowledge of intestinal rotation embryology can prevent intraoperative errors in adult malrotation cases.
• Providing precise iconographic documentation is vital for future surgical interventions in patients with known malrotation.
