Malrotation of bowel: variable patterns with different surgical considerations.

The records of 53 patients with varied roentgenographic patterns of malrotation were reviewed. The patterns were categorized as A-Infantile (Al), A-Adult (Aa), B, C, and D. The differences in form were obvious and each differed clinically, radiographically, and surgically. The differences allowed the development of prognostic insights simply based on the presence and/or position of the ligament of Treitz and the cecum as shown by barium gastrointestinal examination. The literature was reviewed to find supportive or contradictory case material or other data that complemented or devalued the developed system for determining prognosis of patients with varied bowel patterns. The developed prognostic scheme seems to satisfy the requirements of reliability.
