This study was designed to identify factors that predict pain and difficulty during sedation-free colonoscopy. METHODS: A total of 848 consecutive sedation-free colonoscopies were evaluated in a prospective manner. Factors were recorded, including patient pain, intubation time, demographic data, history of abdominal surgery, bowel preparation status, diverticular disease, bowel habits, anxiety level, and number of previous colonoscopies. These factors were analyzed to determine their association with pain and difficulty. RESULTS: Almost all colonoscopies (845/848; 99.6 percent) were successful. Univariate analyses showed that lower body mass index, younger age, female gender, anxiety level, first time, intubation time, preparation status, previous hysterectomy, and previous gynecologic surgery were predictors of patient pain, and lower body mass index, female gender, anxiety level, preparation status, previous hysterectomy, previous gynecologic surge-ry, and constipation were predictors of difficulty of intubation. Multivariate logistic regression analyses revealed that lower body mass index, younger age, intubation time, preparation status, previous hysterectomy, and antispasmodic agent use were predictors of patient pain, and lower body mass index, female gender, constipation, preparation status, and previous hysterectomy were predictors of difficulty of intubation. CONCLUSIONS: By use of intubation time and patient pain, several patient characteristics were identified that may predict technical difficulty and pain associated with the procedure. These findings have implications for the practice and teaching of colonoscopy.展开更多

However, no reports have ever referred to the incidence of ischemic enterocolitis in patients with acute pancreatitis, using a series of autopsy cases. Here, we report our review of autopsy cases of patients with acute pancreatitis to examine the incidence of associated ischemic enterocolitis. Methods: The intestinal and pancreatic slides of 48 autopsy cases of patients with acute pancreatitis were reviewed and the incidence of ischemic enterocolitis was determined. Clinical case records were also reviewed. Results: Thirteen (27% ) of 48 autopsy cases of patients with acute pancreatitis were complicated by ischemic enterocolitis. The frequency of shock was significantly higher in patients with ischemic enterocolitis than in those without ischemic enterocolitis. The intestinal lesion was diffuse in many cases and gangrene was not an unusual finding. Conclusions: The incidence of ischemic enterocolitis in patients with acute pancreatitis was much higher than that in the previous reports. Clinicians who treat patients with acute pancreatitis should consider ischemic enterocolitis as one of the frequent and severe complications of this condition.展开更多
