Item Addition of Low-Dose Ketamine to Midazolam-Fentanyl-Propofol-Based Sedation for Colonoscopy: A Randomized, Double-Blind, Controlled Trial(2015) Tuncali, Bahattin; Pekcan, Yonca Ozvardar; Celebi, Arzu; Zeyneloglu, Pinar; 0000-0002-7898-2943; 0000-0002-0991-7435; 0000-0003-2312-9942; 25801162; AAJ-7840-2021; AAD-5696-2021; C-3736-2018Study Objective: To evaluate the effects of low-dose ketamine on midazolam-fentanyl-propofol-based sedation for outpatient colonoscopy. Design: Prospective, randomized, double-blinded, placebo-controlled trial. Setting: Gastroenterology unit at a practice and clinical research center. Subjects: Ninety-seven healthy American Society of Anesthesiology physical status 1 volunteers. Interventions: Subjects were randomized to receive midazolam (0.02 mg/kg), fentanyl (1 mu g/kg), and ketamine (0.3 mg/kg) and midazolam (0.02 mg/kg), fentanyl (1 mu g/kg), and placebo (0.9% sodium chloride) in group K and group C, respectively. In both groups, incremental doses of propofol were used to maintain a Ramsay sedation score of 3 to 4. Measurements: Values of heart rate, blood pressure, oxygen saturation, and respiratory rate were measured. Procedure times, recovery times, drug doses used, complications associated with the sedation, and physician and patient satisfaction were also recorded. Main Results: In group K, mean amount of propofol used and mean induction time (P < .001), the need for the use of jaw thrust maneuver and mask ventilation, and the incidence of disruptive movements were significantly lower (P < .05) and gastroenterologist satisfaction at the beginning of the procedure was significantly superior (P < .05). Mean systolic blood pressures at 4, 6, 8, and 10 minutes (P < .01); diastolic blood pressures at 4, 6, and 8 minutes (P < .05); respiratory rates at 4, 6, 8, 10, 15, 20, and 25 minutes (P < .01); and oxygen saturation at 6, 8, 10, 15, and 20 minutes (P < .05) were significantly lower in group C. Patient satisfaction scores, recovery times, and discharge times were similar. No patient in either group experienced unpleasant dreams or hallucination in the postanesthesia care unit and on the first postoperative day. Conclusions: Addition of low-dose ketamine to midazolam-fentanyl-propofol-based sedation for outpatient colonoscopy resulted in more rapid and better quality of sedation, less propofol consumption, more stable heinodynamic status, and less adverse effects with similar recovery times in adult patients.

Yilmaz; 0000-0002-5214-516X; 0000-0001-9580-7656; 28739021; ABG-5684-2020; AAB-4153-2020; AAF-2109-2021Background: Food protein-induced allergic proctocolitis is a frequent cause of rectal bleeding in infants. Characteristics of infants with multiple food allergies have not been defined. Objective: This study aimed to identify characteristics of infants with proctocolitis and compare infants with single and multiple food allergies. Methods: A total of 132 infants with proctocolitis were evaluated retrospectively. All of the infants were diagnosed by a paediatric allergist and/or a paediatric gastroenterologist according to guidelines. Clinical features of the infants, as well as results of a complete blood count, skin prick test, specific immunoglobulin E, and stool examinations or colonoscopy were recorded. Results: Cow's milk (97.7%) was the most common allergen, followed by egg (22%). Forty-five (34.1%) infants had allergies to more than one food. Infants with multiple food allergies had a higher eosinophil count (613 +/- 631.2 vs. 375 +/- 291.9) and a higher frequency of positive specific IgE and/or positive skin prick test results than that of patients with a single food allergy. Most of the patients whose symptoms persisted after two years of age had multiple food allergies. Conclusions: There is no difference in clinical presentations between infants with single and multiple food allergies. However, infants with multiple food allergies have a high blood total eosinophil count and are more likely to have a positive skin prick test and/or positive specific IgE results. (C) 2017 SEICAP.

CPs are focal lesions and incidence increases with age. Aim: In this study, we aimed to analyze retrospectively the relationship between the EPs and CPs sharing similar clinical and genetic factors in their etiopathogenesis. Materials and Methods: This study was retrospectively performed between 2010 and 2013 and it included patients diagnosed to have eEPs. The study group and the control group consisted of patients who were diagnosed with or without EPs and who underwent colonoscopy at the same period. Results: The study group was formed by 57 patients with diagnosis of EP who underwent colonoscopy during the same period. The control group consisted of 71 patients without EP examined with colonoscopy. Among 128 patients assessed in this study, 24 were diagnosed with CPs, all of which were adenomatous polyps smaller than 1 cm. No hyperplastic or inflammatory polyps were diagnosed. While 18 of 57 patients with EPs had CPs, 6 of 71 control subjects had CPs. Hence, the risk of having CP was 5 times greater in patients with EP compared to those without (P < 0.05). Conclusion: The present study demonstrated that the prevalence of CPs increased significantly in postmenopausal patients with EPs. Recommending colonoscopy to these patients irrespective of age may be beneficial for detecting more CPs and preventing colorectal cancer.Item Gastrointestinal endoscopy in pregnancy(2014) Savas, Nurten; 25386072Gastrointestinal endoscopy has a major diagnostic and therapeutic role in most gastrointestinal disorders; however, limited information is available about clinical efficacy and safety in pregnant patients. The major risks of endoscopy during pregnancy include potential harm to the fetus because of hypoxia, premature labor, trauma and teratogenesis. In some cases, endoscopic procedures may be postponed until after delivery. When emergency or urgent indications are present, endoscopic procedures may be considered with some precautions. United States Food and Drug Administration category B drugs may be used in low doses. Endoscopic procedures during pregnancy may include upper gastrointestinal endoscopy, percutaneous endoscopic gastrostomy, sigmoidoscopy, colonoscopy, enteroscopy of the small bowel or video capsule endoscopy, endoscopic retrograde cholangiopancreatography and endoscopic ultrasonography. All gastrointestinal endoscopic procedures in pregnant patients should be performed in hospitals by expert endoscopists and an obstetrician should be informed about all endoscopic procedures. The endoscopy and flexible sigmoidoscopy may be safe for the fetus and pregnant patient, and may be performed during pregnancy when strong indications are present. Colonoscopy for pregnant patients may be considered for strong indications during the second trimester. Although therapeutic endoscopic retrograde cholangiopancreatography may be considered during pregnancy, this procedure should be performed only for strong indications and attempts should be made to minimize radiation exposure.

However, none of the currently available colonoscopy preparation regimens is safe, efficient, and comfortable. The aim of this study was to determine whether adding stewed apricot juice to senna increased patient comfort and improved bowel cleansing during colonoscopy preparation. Methods: Outpatients of both genders who were over 18 years old and were referred for elective colonoscopy were randomly allocated to drink stewed apricot juice with senna or senna by itself. The quality of the colon cleansing was evaluated using the Ottawa scale. Patient tolerance and adverse events were evaluated through the completion of a questionnaire. Results: The study included a total of 128 patients in the randomization procedure. A significantly greater cleansing effect was observed using stewed apricot juice plus senna in the right and transverse colon (p = 0.038, p = 0.037 respectively). It was also determined that in the stewed apricot juice plus senna group, overall cleansing was superior (p < 0.001), total colonoscopy (17.6 min vs. 22.8 min, p = 0.048) and cecal intubation (7.4 min vs. 11.2 min, p = 0.042) times were shorter, and the colonoscopy procedure was easier (79.4% vs. 49.2%, p < 0.001). No differences were observed between the groups with respect to patient acceptance, compliance, and adverse events. In the stewed apricot juice plus senna group, 91.2% of patients stated their willingness to receive the same regimen in the future compared to 80% of the patients in the senna alone group (p = 0.037). Conclusion: The addition of natural, stewed apricot juice to senna significantly improves cleansing outcomes without additional adverse effects.Item Ambulatory colonoscopy under sedoanalgesia in adult patients with and without irritable bowel syndrome: A prospective, cross-sectional, and double-blind comparison(2018) Tuncali, Bahattin; Araz, Coskun; Celebi, Arzu; 29755018Background/Aims: it is unclear whether patients with irritable bowel syndrome (IBS) require a high dose of sedatives during colonoscopy. In this study, we investigated the pre-procedural anxiety levels, sedative consumption, procedure times, complications, and patient's satisfaction between patients with IBS and controls for ambulatory colonoscopy under sedation. Materials and Methods: Rome III criteria were used in the diagnosis of IBS. Anxiety levels were measured using Spielberger's State-Trait Anxiety Inventory (STAI) and Beck Anxiety Inventory (BA/). Patients received a fixed dose of midazolam (0.02 mg/kg), fentanyl (1 mu g/kg), ketamine (0.3 mg/kg), and incremental doses of propofol under sedation protocol. Demographic data, heart rate, blood pressure, and oxygen saturation were measured. Procedure times, recovery and discharge times, drug doses used, complications associated with the sedation, and patient's satisfaction scores were also recorded. Results: The mean Trait (p=0.015), State (p=0.029), Beck anxiety scores (p=0.018), the incidence of disruptive movements (p=0.044), and the amount of propofol (p=0.024) used were significantly higher in patients with IBS. There was a decline in mean systolic blood pressure at the 6th minute in patients with IBS (p=0.026). No association was found between the sedative requirement and the anxiety scores. Conclusion: Patients with IBS who underwent elective colonoscopy procedures expressed higher pre-procedural anxiety scores, required more propofol consumption, and experienced more disruptive movements compared with controls. On the contrary, the increased propofol consumption was not associated with the increased pre-procedural anxiety scores.
