Abstract
Overweight and obesity are defined as abnormal or excessive fat
accumulation that may impair health, it carries a high risk for development of
chronic comorbidities as type 2 diabetes, hypertension and cardio vascular diseases.
Small bowel length has been proved to positively correlate with body mass index
(BMI), while some studies proposed that bypassing proximal part of small intestine
provide better glycemic control for type 2 diabetic patients.
Aim of the study: Identify the correlation between length of the small intestine
and type 2 Diabetes mellitus after adjustment for Age, gender, body mass index,
and glycemic control.
Patients and methods: we conducted a prospective cross section study that included
patients who are admitted to Kasr Alainy hospital with indication for abdominal
exploration such as penetrating or blunt abdominal trauma, measurement of small
bowel starting at ligament of Treitz ending at ileocecal valve using a sterile 10 cm -
tape applied to the anti-mesenteric border, patients aged <18 years or presented with
peritonitis, GIT malignancy and had history of previous abdominal operation are
excluded.
Results: 268 patients were included in our final analysis (167 males, 101 females)
they had a mean age 46 ± SD 16 years, Mean length of the small intestine 409 ± SD
52 cm. Total small bowel length was significantly longer among non-diabetic group
413 ± SD 53 cm versus 383± SD 30 cm in the diabetic group with p value 0.0001.
BMI was significantly higher among diabetic group with p values 0.0001.
Conclusion: Type 2 diabetes mellitus is associated with shorter small bowel, Total
length of small bowel was significantly shorter in patients with higher RBS > 200
mg/dl and higher HBA1c > 6.5%.
