STUDY OBJECTIVE: To establish the location of the transverse colon in relationship to the umbilicus, and determine if it varies as a function of patient height or weight.
DESIGN: Retrospective review of computed tomograms (CT) of the abdomen (Canadian Task Force classification II-2).
SETTING: University hospital.
PATIENTS: Sixty-seven women with normal abdominal anatomy.
INTERVENTION: Review of abdominal CT scans.
MEASUREMENTS AND MAIN RESULTS: The relative relationships of the transverse colon and umbilicus were compared with age, height, weight, and body mass index (BMI = kg/m2) using multiple regression analysis. Average location of the superior margin of the transverse colon was 4.6 cm (95% CI 3.5-5.7 cm) above the umbilicus. In nine (13%) women it was below the umbilicus. The colon was below the umbilicus in 25% of nonobese women (BMI <25 kg/m2).
CONCLUSION: Because the transverse colon lies below the umbilicus in more than 10% of women, injury to it may be an uncommon yet unavoidable complication of laparoscopy.
