Correlations between duodenal loop size and external body measurements

Measurements of the area, height and width of duodenal loops in male and female controls were correlated with their body height, weight, surface area, lean body mass and adjusted body surface area in order to assess the possibility of predicting loop size from body habitus. In male subjects the most marked correlations were between bodyweight and loop area ( r = 0.58) and between true body surface area and loop area ( r = 0.57). No relationship was observed between the size of the duodenal loop and body size in females.
