Active clinical trials for "Dilatation, Pathologic"

This project has 2 phases. Phase 1: diagnostic test study, to evaluate the efficacy of the variation of pupillary size (PDR) to detect pain in ICU patients regarding to Behavioural Pain Scale (BPS) and ESCID (Conductual Scale Pain Index). Phase 2: controlled and aleatorized clinical trial to evaluate efficacy in PDR monitoring after painful assessed minimum stimulus with the best diagnostic efficiency on phase 1, as a need of analgesia indicator tool. The sample will be patients over 18 years, sedated and mechanically ventilated, with an initial BPS of 3, RASS between -1 and -4, not able not to communicate , with inform consent signed. Exclusion criteria will be: ophtalmologic pathology and administration of drugs interfering pupillary reflexes. Measurements before/during pain/non-pain situations, aspiration of secretions and calibrated intensity stimulus through the pupilometer Algiscan. The investigators will study association between pain according to BPS/ESCID and pupillary dilatation according to pupillometry and percentage of patients with pain and preanalgesia according to pupillometry and standard clinical practice.

Laparoscopic cholecystectomy is the first-line treatment for symptomatic gallstones. Pneumoperitoneum is the process of expanding the abdominal cavity during the surgical procedure by introducing CO2 gas into the abdomen to widen the field of view and operation. Although CO2 gas is usually released through the subumbilical incision at the end of laparoscopic cholecystectomy, some CO2 gas remains in the peritoneal cavity. This CO2 gas remaining in the peritoneal cavity can cause abdominal distension. Abdominal distension may also increase postoperative pain. In a study, abdominal distension was observed in 42.7% of patients who underwent laparoscopic surgery under general anesthesia. Although CO2 gas is usually released through the subumbilical incision at the end of laparoscopic cholecystectomy, some CO2 gas remains in the peritoneal cavity. This CO2 gas remaining in the peritoneal cavity may cause abdominal distension. On the other hand the incidence of shoulder pain due to pneumoperitoneum and CO2 insufflation after laparoscopic surgery ranges from 35% to 60%. In a study conducted in the Republic of Korea in 2016 in 105 laparoscopic surgery patients, the incidence of shoulder pain after laparoscopy was found to be 80% in the first 24 hours. Inappropriate treatment of postoperative pain in laparoscopic surgery can lead to delayed mobilization, patient dissatisfaction, delayed hospital discharge, and development of chronic pain. In this study, the effect of respiratory exercises and the use of incentive spirometry in the early postoperative period on abdominal distension, shoulder pain and mobilization process in laparoscopic cholecystectomy patients will be examined. We aimed to evaluate the effect of deep breathing exercises and the use of incentive spirometry in the early postoperative period on abdominal distension and shoulder pain due to insufflation procedure in laparoscopic cholecystectomy patients. It is important to take some precautions from the early period to prevent problems that may develop after abdominal surgery. It is thought that the use of deep breathing exercises and incentive spirometry in the early period after laparoscopic cholecystectomy will have an effect on abdominal distension, shoulder pain and mobilization process due to the insufflation procedure.

Aim:To examine the effect of "Paula Method Exercises" after cesarean section on the prevention of postoperative distention and pain due to distension. Method: The study was planned as a double-blind, randomized controlled experimental study. The study was carried out between November 2021 and February 2022 with women who had undergone cesarean section at Akdeniz University Hospital Gynecology and Obstetrics Clinic and agreed to participate in the study. The number of individuals to be sampled from the population was determined by the G Power analysis and 80 women were included in the sample. The data of the study were collected using the Introductory Information Form, the Postoperative Follow-up Form, and the McGill Pain Scale Form. The women in the intervention group were given training on how to do the Paula Method Exercises in the postoperative period in line with the "Paula Method Exercises Training Plan" by the researcher. Conclusion: It is predicted that the findings obtained from the data of the study will guide nursing care practices and new researches for the relief of gas and distension after cesarean section.

Gastric antral vascular ectasia (GAVE) is a condition that can lead to blood loss in the gastrointestinal tract and low blood counts or anemia. 1,2 GAVE is commonly associated with liver disease, kidney disease and autoimmune immune problems, but can also be seen in patients without those problems. 2-4 It is common for GAVE to cause hospitalization of patients and significant blood transfusion requirements. Given these problems, effective treatment of GAVE is needed to reduce these potential problems. These treatments are performed by a gastroenterologist through a flexible endoscope most often with argon plasma coagulation (APC).5-7 APC is only partially successful at eradicating GAVE and often entails repeated endoscopic procedures. Therapy with APC can also cause ulceration at times resulting in acute bleeding. Cryoablation is an attractive alternative to APC as it should not cause increased blood loss and case reports suggest that ablation may be achieved with limited number of endoscopic sessions. Prior problems with endoscopic cryotherapy include the high flow of gas and risk of perforation.8,9 A recent retrospective investigation by this group has evaluated the first generation cryotherapy balloon, demonstrating clinical safety and efficacy for GAVE.10 A new balloon cryotherapy spray device was recently developed and does not require venting. In this study we plan to prospectively evaluate the use of balloon cryotherapy to treat GAVE. We predict that the therapeutic response of balloon cryotherapy will be greater than 80% effective at achieving clinical success or the loss of overt bleeding and need for packed red blood cell (PRBC) transfusion at 6 months after treatment.

The study aims to evaluate the effects of cervical dilatation during cesarean section on postoperative maternal morbidity through different clinical parameters.

We have developed novel Brillouin microscopy and we are testing its potential for keratoconus and ectasia diagnostics. We plan to perform axial scans of the cornea in human volunteers in order to compare biomechanical properties of Keratoconus vs. Normal corneas and compare biomechanical properties of post-LASIK ectasia vs. normal corneas.

The investigator's goal is to improve the patient's compliance and accurate capture of patient reported gas and bloating symptoms, by utilizing a phone application that interactively records each gas and bloating event in addition to bowel events and other bowel symptoms. Such an electronic stool diary may relieve the burden of using a paper daily stool diary. The investigator will compare and validate the electronic gas and bloating diary with the paper gas and bloating diary.

The maximal diameter of the pancreatic duct will be measured by endoscopic ultrasound at four different parts: Pancreatic head Pancreatic neck Pancreatic body Pancreatic tail

The goal of this observational study is to assess the changes of ascending aortic diameter in patients undergoing transcatheter aortic valve replacement. The main questions it aims to answer are: whether the ascending aortic diameter increases or remains stable after transcatheter aortic valve replacement, especially in patients with preoperative ascending aortic dilatation; the determinants of postoperative ascending aortic dilatation.

As a consequence of chronic relapsing inflammation in Crohn's disease (CD), progressive bowel damage and scarring occurs in affected regions of intestine. This damage often leads to narrowing, or stricturing of the bowel lumen, and even complete bowel obstruction. Stricturing CD is thought to be a major contributor to penetrating complications including abscesses and fistulae. Depending on the severity and clinical significance of fixed strictures, treatment options include either endoscopic balloon dilatation (EBD), or surgery with either resection or stricturoplasty recommended on a case-by-case basis. EBD has been shown to be a safe alternative to surgery in management of CD strictures. While the short- and medium-term clinical outcomes of EBD have been well described, less well studied is the impact of relieving Crohn's strictures on the inflammatory load proximal to the stricture. The restricted flow of fecal contents through a stricture creates a region of relative stasis in the bowel loops immediately proximal to the stricture, appreciated at times by pre-stenotic dilatation on cross-sectional imaging. This stasis fosters localized bacterial overgrowth and worsening dysbiosis in these bowel loops. The investigators hypothesize that improvement of fecal flow by way of successful balloon dilatation of a CD stricture, could independently reduce the inflammatory burden, not only in the stenotic segment but also in the proximal loop of bowel.
