Randomized Controlled Trial Comparative Study
Does adding misoprostol to standard intravenous proton pump inhibitor protocol improve the outcome of aspirin/NSAID-induced upper gastrointestinal bleeding?: a randomized prospective study.
Aspirin and nonsteroidal anti-inflammatory drug (NSAID)-induced gastrointestinal bleeding is recognized as an important health problem. We performed a single-center randomized clinical trial to compare the effect of high-dose intravenous proton pump inhibitor (omeprazole) alone (group 1) with omeprazole in combination with a low-dose prostaglandin analog (misoprostol; group 2) on clinical outcomes in patients with aspirin/NSAID-induced upper gastrointestinal bleeding. Additionally, we evaluated the contribution of Helicobacter pylori eradication therapy on the late consequences. ⋯ In this pilot study, we indicated that adding misoprostol (600 microg/day) to standardized proton pump inhibitor treatment did not improve or change the rebleeding or mortality rates of patients with upper gastrointestinal bleeding related to aspirin/NSAID use. Other prospective studies on higher doses of misoprostol are needed to establish the coeffect. One should bear in mind that all blood products must be irradiated before transfused to the host.

Randomized Controlled Trial Comparative Study
Fentanyl or tramadol, with midazolam, for outpatient colonoscopy: analgesia, sedation, and safety.
The present study determined the acceptability of colonoscopy in outpatients treated with tramadol or fentanyl for analgesia and sedation. One hundred fifty patients were randomly assigned to receive midazolam, 0.05 mg/kg, and fentanyl, 2 microg/kg, intravenously (group 1), midazolam, 0.05 mg/kg, and tramadol, 1 mg/kg, per os (group 2), or midazolam, 0.05 mg/kg, and tramadol, 2 mg/kg, per os (group 3). Pain severity, level of sedation, cardiorespiratory parameters, and procedure-related side effects and complications were registered and analyzed. ⋯ Pain severity values measured during the procedure was significantly higher in groups 2 and 3 than in group 1 (P < 0.001). Both hospital and home adverse events occurred more frequently in groups 2 and 3 compared to group 1 (P < 0.03). The patients receiving fentanyl-based analgesia tolerated colonoscopy better than patients treated with tramadol.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of air-coupled balloon esophageal and anorectal manometry catheters with solid-state esophageal manometry and water-perfused anorectal manometry catheters.
Clinical gastrointestinal manometry studies are currently performed with multilumen water-perfused polyvinyl or strain gauge sensor solid-state catheters. A disposable catheter incorporating air-filled balloons has been developed with performance characteristics suitable for esophageal and anorectal manometry studies. ⋯ Correlation coefficient analysis demonstrated that LES pressures, esophageal contraction amplitudes, and anorectal resting and squeeze pressures were not significantly among between the different catheters. We conclude that recently developed air-filled balloon esophageal and anorectal manometry catheters provide very similar measurements of LES, esophageal body, and anorectal sphincter pressures compared to presently used manometry catheters.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of fentanyl versus meperidine for analgesia in pediatric gastrointestinal endoscopy.
This study compared the safety and efficacy of fentanyl and meperidine for analgesia in pediatric gastrointestinal endoscopy. In a double-blind, randomized trial, 24 patients (11 males) received either fentanyl (1 microg/kg) or meperidine (1 mg/kg). These analgesics were administered in unmarked syringes by an investigator who did not participate in the procedure or in the evaluation of the patient's sedation. ⋯ Study subjects underwent EGD (n = 17) or colonoscopy (n = 7). There were no differences as assessed by patient, endoscopist, or assistant for tolerance, discomfort, procedure ease, recovery time, complications, heart rate, blood pressure, or oxygen saturation. We conclude that meperidine and fentanyl are equally effective in providing analgesia for pediatric gastrointestinal endoscopy.

Randomized Controlled Trial Comparative Study Clinical Trial
Operative stress response is reduced after laparoscopic compared to open cholecystectomy: the relationship with postoperative pain and ileus.
Our objective was to determine the least invasive surgical procedure; to do this we compared postoperative pain, duration of ileus, and level of neurohormonal stress response after laparoscopic cholecystectomy (LC) and open cholecystectomy (OC). Postoperative recovery of patients was faster after LC than OC but comparison of the neurohormonal stress response after laparoscopic and open surgical procedures revealed conflicting results. Forty-one consecutive patients with noncomplicated gallstones were randomized for LC (N = 25) and OC (N = 16). ⋯ When the time to first passage of flatus was delayed, levels of BE, ACTH, and catecholamines and NT concentrations were increased (P < 0.05-P < 0.005). In conclusion, LC is less invasive because this surgical procedure induces a shorter neurohormonal stress response than OC, even if the peroperative response is not different. Postoperative pain levels and the duration of ileus are associated with BE, ACTH, and catecholamine levels and NT concentrations, suggesting the importance of hormones in postoperative functional recovery.
