Introduction: The primary function of small bowel is digestion and absorption of dietary components after
they leave the stomach. The enlarged surface area of small intestine enables complete digestion of food stuffs.
Investigators has correlated the length of small bowel with age, gender, height, and weight.
Aim of work: To asses intraoperatively the small bowel length measurements and analysis of demographic
predictors of increased length.
Patients and methods: This cross-sectional study was conducted in Emergency Department of Cairo University
hospital from January 2021 to June 2021. We included 160 patients who have been admitted to general surgery
department of Kasr Alainy who were indicated for abdominal surgery. Measurement the of the small bowel is
expressed in centimeters, starting at ligament of Treitz and ending at the ileocecal junction using a sterile 10 cmtape
applied to the anti-mesenteric border of un stretched small intestine.
Results: The current study showed that there was very high positive correlation according to weight and height
while BMI shows no significant correlation between them. We also found that there were highly statistically
significant differences between sex groups according to age, height, BMI and Total small bowel length. In males,
there was very high positive significant correlation according to weight and height. In females, there was very high
positive significant correlation according to height.
Conclusion: Length of the small bowel in humans is pertinent to advances in deep enteroscopy and existing
surgical applications such as intestinal bypass and prevention of short gut syndrome.
