Active clinical trials for "Ileus"

Postoperative ileus (POI) is a significant complication after colorectal surgery, with reported incidence ranging from 10~30%, leading to increased morbidity, hospital length of stay, and thus medical cost. To determine the risk factors for POI is one of the key elements for Enhanced Recovery after Surgery protocol. Increased perioperative opioid usage has been proposed as an independent risk factor for postoperative ileus, as perioperative opioid minimization has proposed to be an effective measure to decrease the incidence of POI. Although opioids are widely used to attenuate stress during surgery, and represent the cornerstone of pain treatment, anesthesiologists are strive to minimize opioid use to decrease opioid-related GI side effects. In this study, the investigators aim to find out the general occurrence of POI in the laparoscopic colorectal surgery and the effects of the postoperative opioid usage on this outcome. The strategies of opioid minimization was also investigated.

Postoperative ileus and opioid induced constipation are well-known post-operative complications. Previously, research has shown that using peripherally acting opioid antagonists can help alleviate the condition. There has not been a prospective study to investigate whether use of peripherally acting opioid antagonists are effective in preventing post-operative ileus in patients having spinal fusion surgeries.

Postoperative ileus (POI) is a frequent complication after abdominal surgery leading to nausea, vomiting and infectious complications. Bowel dysmotility can last for days and necessitates parenteral nutrition resulting in an prolonged hospital stay and a high economic burden. Until now there is no evidence based therapy of manifest POI because of missing valid surrogate markers demonstrating the severity and resolution of POI. A novel tool to examine gastrointestinal function is the SmartPill®. By measuring pH value, temperature and intraluminal pressure the capsule is able to analyse gastric emptying, small bowel transit, large bowel transit and peristaltic activity. Unfortunately the use of the SmartPill® is not allowed in the first three months after abdominal surgery. Therefore a trial is needed to investigate the behaviour of the SmartPill® during its passage through the human gastrointestinal tract immediately after surgery. The primary endpoint is - to investigate the safety of the SmartPill® in patients after abdominal surgery. The secondary endpoints are: is the SmartPill® able to detect the gastrointestinal transit and the peristaltic activity followed by abdominal surgery compared with patients which underwent thoracic/vascular surgery. is it possible to correlate the measured parameters (delayed gastrointestinal transit, lack of peristalsis) with the clinical signs of POI (nausea, vomiting, prolonged duration until first postoperative defecation). is the detected peristaltic activity influenced by intravenous applicated prokinetic drugs is the detected peristaltic activity influenced by physiotherapy Using those endpoints the investigators hope to demonstrate the safety of the SmartPill® after abdominal surgery, to evaluate its ability to analyse severity and length of POI and to examine whether the used prokinetic drugs and postoperative mobilization are able to influence peristaltic activity.

A multicenter randomized-controlled trial of daikenchuto (TJ-100), a traditional Japanese herbal medicine (Kampo), to investigate its effect on intestinal dysmotility and for the prevention of postoperative paralytic ileus.

This is a study to evaluate whether use of a pedometer following radical cystectomy decreases post-operative narcotic use and time to return of bowel function.

The General Objective of this study is to investigate the cost and efficacy of treating patients undergoing colorectal surgical resections with an opioid limited pain control regimen as part of an Enhanced Recovery After Surgery (ERAS) Protocol. This group will be compared to a traditional opioid based pain control regimen.

The goal of this study is to learn if electro-acupuncture is a feasible treatment option for postoperative ileus after abdominal surgery. The second goal of this study is to evaluate the time to resolution of postoperative ileus after receiving electro-acupuncture treatments.

Postoperative ileus (POI) after lumbar spine surgery is not uncommon. However, the incidence, severity and risk factors of ileus after spine surgery remain uncertain because there is not yet a prospective investigation using a subjective grading evaluation tool.

Assess whether the application of electrical stimulation in patients undergoing subcutaneous colon cancer in a Multimodal Rehabilitation Program (Fast track) decreases the incidence of postoperative ileus, improving the results of morbidity and mortality, hospitalization and health care costs.

A prospective study to compare the postoperative ileus in open and laparoscopic gastrointestinal surgery through the determination of the time the patient takes to pass flatus, pass stool, bowel movement, oral intake, the time of hospital stay and total hospital costs. Postoperative ileus (POI) is one of the major focus of concern for surgeons, hospital executives, quality assurance directors as well as patients because of its role in causing patient distress, discomfort, and morbidity, leading to an increase in the duration of hospital stay and cost of care.
