Filter by:Postoperative ileus is a frequently occurring surgical complication. It is defined as temporary inhibition of propulsive bowel activity and is manifested by abdominal distention, nausea, vomiting and diet intolerance. It may lead to a prolonged hospital stay, hospital-acquired infections or complications that may require additional treatments (e.g. analgesia, fluids, electrolyte replacement, nasogastric tube decompression), and as a result increase medical costs. Previous studies showed that postoperative coffee consumption shortens the time to first bowel movement after colorectal resections. However, none could explain the mechanism by which coffee stimulates intestinal motility and the determinant agent for this action is still up for discussion (either caffeine or another coffee component). Coffee has a negligible caloric content; It has a pH that varies from 5 to 6 (less acidity than other beverages that have no similar effect on bowel motility) and it is hypotonic. Therefore, it is highly unlikely that bowel motility is due to the physical properties of the coffee. Much more likely, that one (or more) of the numerous phytochemicals of the coffee bean are responsible for this effect, when the most obvious candidate seems to be caffeine. However, as mentioned above, very little evidence exists that caffeine was responsible for the observed effect on colonic function in previous studies. The purpose of this single-centered, prospective, single blinded, randomized clinical trial is to evaluate whether the use of caffeine in the post-operative period significantly reduces the duration of postoperative ileus, and therefore, improves recovery and shorten the hospital stay. The study hypothesis is that post-operative use of caffeine will reduce time to recovery of GI function (post-operative ileus) by at least 15 hours and thus reduce hospital length of stay by at least 15 hours in patients undergoing elective colorectal operations. 50 patients due to undergo large bowel resection via laparotomy or laparoscopy will be enrolled and randomized (1:1) to those who will receive caffeine (100 mg 3 times per day) and those who will receive placebo (tap water) starting on the morning of postoperative day 1 after surgery until flatus will occur for the first time or to a maximal period time of 7 days, whichever comes earlier.
Postoperative ileus (POI) refers to the period of gut dysmotility that occurs after abdominal surgery. Patients with POI are unable to eat, suffer ongoing nausea and vomiting, are unable to open their bowels and have a prolonged hospital stay. Research at ADHB shows that 25% of patients will have a prolonged POI after elective bowel resection, which makes it the most common major complication after colorectal surgery. Clinicians currently lack a definitive medication to prevent or treat POI, which means POI causes patients ongoing morbidity and places a significant drain on healthcare resources. Serotonin plays an important role in gut motility. Evidence suggests that serotonin agonists, such as prucalopride, increase gut transit and may have anti-inflammatory properties. The hypothesis of this study is that Prucalopride given pre-operatively and continued post-operatively in patients having an elective bowel resection will improve gut function recovery after surgery and reduce POI. The investigators' proposed study is a double-blinded randomised controlled trial of prucalopride compared to an identical placebo tablet, in patients having an elective bowel resection at Auckland City Hospital. Patients will receive a single tablet of Prucalopride or placebo 2-3 hours preoperatively and then daily after operation for a maximum of 6 days. The primary endpoint will be return to bowel function defined by the time to tolerate a solid diet and pass stool. In addition, the investigators plan to assess postoperative gastric emptying rates using the safe and non-invasive carbon breath test method. This will allow the investigators to determine the effects of prucalopride on the stomach, and support its role as a gastric prokinetic.
The purpose of this study is to establish preliminary evidence of the efficacy, safety, and tolerability of LB1148 for the treatment of post-operative ileus and intra-abdominal adhesions in subjects undergoing elective bowel resection.
Postoperative ileus (POI) causes patient's discomfort and leads to an increase of cost of management after colorectal surgery because of an increase of the morbidity rate or of the rate of early rehospitalization after discharge. Enhanced recovery programs allowed a reduction of its rate but 20 to 30% of patients will experiment POI. A new approach during preoperative era, using mastication or preoperative physical activity, has been proposed to improve postoperative course. This leads to a vagal activation (action especially on upper GI). Sacral stimulation using percutaneous tibial nerve stimulation (PTNS) has an effect on lower GI. The aim of this study was to assess the efficacy and the feasibility of PTNS during perioperative course, to prevent POI with respect with placebo.
Cesarean section will performed via intraperitoneally and extraperitoneally. During postoperative period pain, need for analgesia, respiratory function tests, ileus, bowel movement, discharged time will be compared.
Postoperative ileus is the most commonly observed morbidity following ileostomy closure. Studies have previously demonstrated that the defunctionalized bowel of a loop ileostomy undergoes a series of functional and structural changes. It has been hypothesized that these changes may contribute to the development of postoperative ileus, and that stimulating the distal limb of a loop ileostomy prior to closure may functionally prepare the excluded bowel for intestinal transit. The purpose of the multicenter, randomized controlled trial is to determine the impact of preoperative stimulation of the distal limb of a loop ileostomy on postoperative ileus.
Hypothesis: Electrical stimulation of the abdominal vagus nerve has anti-inflammatory effects which lead to a faster postoperative recovery after abdominal surgery. Aims: In the present study, the investigators want evaluate the anti-inflammatory effect of peroperative electrical stimulation of the vagus nerve. In addition, the investigators want to determine whether vagus nerve stimulation leads to a faster postoperative recovery. To this end, the following aims are formulated: 1. to determine whether vagus nerve stimulation leads to an improvement in gastrointestinal transit using radiological testing 2. to evaluate whether electrical stimulation of the vagus nerve leads to clinical improvement (daily questionnaire) 3. to show that electrical stimulation of the intra-abdominal vagus nerve reduces the inflammatory response to abdominal surgery
The investigators try to find whether thoracic epidural analgesia (TEA) shortens the first gas-out time compared to iv-PCA and promotes earlier discharge after major upper abdominal surgery.
Postoperative ileus (POI) is a common problem after major abdominal surgery. Acupuncture is being accepted in the West as a treatment option for managing POI and various functional gastrointestinal disorders. Therefore, we conducted a prospective randomized pilot study to evaluate the effect of electro-acupuncture on POI and other surgical outcomes in patients who underwent gastric surgery for a later large-scale study.
The aim of the study is to investigate if postoperative coffee intake decreases the time until first bowel movement in elective colorectal surgery with primary anastomosis.
