Background/Aims:Obesity is a much-debated factor with conflicting evidence regarding its association with cecum intubation rates during colonoscopy. We aimed to identify the association between cecal intubation (CI) time and obesity by eliminating confounding factors.Methods:A retrospective chart review of subjects undergoing outpatient colonoscopy was conducted. The population was categorized by sex and obesity (body mass index [BMI, kg/m2]: I, <24.9; II, 25 to 29.9; III, ≥30). CI time was used as a marker for a difficult colonoscopy. Mean CI times (MCT) were compared for statistical significance using analysis of variance tests.Results:A total of 926 subjects were included. Overall MCT was 15.7±7.9 minutes, and it was 15.9±7.9 and 15.5±7.9 minutes for men and women, respectively. MCT among women for BMI category I, II, and III was 14.4±6.5, 15.5±8.3, and 16.2±8.1 minutes (p=0.55), whereas for men, it was 16.3±8.9, 15.9±8.0, and 15.6±7.2 minutes (p=0.95), respectively.Conclusions:BMI had a positive association with CI time for women, but had a negative association with CI for men.

A decremental trend was observed in ADR and AADR across group 1, group 2 and group 3 (p value >0.05).

Insulin is a debatable risk factor for colon adenoma (Ad) among type II diabetes mellitus (DM II) patients. Obesity is an important confounding variable. The study involved chart review of DM II patients undergoing screening colonoscopy. Study population was divided into obese [body mass index (BMI)≥30] and nonobese (BMI&lt;30) groups which were further divided into insulin and non-insulin subgroup. Colonoscopy and pathology reports were used to calculate Ad detection rate (ADR) and AAd detection rate (AADR). A total of 538 subjects satisfied the inclusion and exclusion criteria. The study population composed of 52.8% obese and 47.2% non-obese subjects. Obese group had 28.9% insulin and 71.1% non-insulin subjects. Non-obese group composed of 29.9% insulin and 70.1% non-insulin subjects. ADR for non-obese insulin and non-insulin subgroup was 31.6% and 37.1% respectively. AADR for non-obese insulin and non-insulin subgroup was 13.2% and 11.2% respectively. ADR for obese insulin and non-insulin subgroup was 41.5% and 34.2% respectively. AADR for obese insulin and non-insulin subgroup was 15.9% and 16.3% respectively. Insulin exposure lacked statistically significant association with ADR or AADR among obese and non-obese DM II subjects.

subphrenic abscess and into the right lower bronchus. Upper GI endoscopy was performed to control the 5 mm fistula with fibrin glue plugging and fistula opening closure with over-the-scope clips. Results: On 3 week follow-up, an abscessogram demonstrated resolving of the subphrenic abscess and confirmed closure of the duodenal fistula. However, there was persistence of the track across the diaphragm into the bronchial tree. Despite this, serial chest imaging showed improvement in the right lower lobe consolidation and patient has no evidence of sepsis. Conclusion: Small duodenobronchial fistulas can be managed non-surgically with endoscopic and interventional radiologic techniques.
