Active clinical trials for "Intestinal Obstruction"

This study is investigating the effect of intraoperative Noradrenaline on cardiac preload and stroke volume, after initial fluid resuscitation, in order to assess whether there is a masked preload responsiveness and ultimately whether the correction of this potential preload-responsiveness with fluid therapy will translate into increased tissue perfusion in emergency laparotomy.

For uncomplicated acute small bowel obstruction (aSBO), the "Bologna guidelines" recommend non-surgical management of 72 hours before considering surgery. This treatment is based on the placement of a nasogastric tube and the correction of hydro-electrolyte disorders. Non-surgical management is only effective in 60 to 70% and surgery is therefore necessary in 30 to 40% of cases after medical treatment for at least 3 days. This therefore leads to an increase in the length of hospital stay. Some authors also point out that postponing surgery for 3 days would aggravate the morbidity and mortality of surgery. Indeed, aSBO surgery has a complication rate of 10-40% and a mortality of up to 4%. There is a lack of studies evaluating what is the best management strategy for aSBO, especially with regard to the duration of medical treatment. Many recent studies plead in favor of early surgical treatment (<24 hours) which would reduce the morbidity and mortality rate of surgery but also the overall cost of treatment by reducing the length of stay. This paradigm shift is linked to the improvement of anesthetic and intensive care management over the last few years, but also to the advent of laparoscopy in emergency surgery. Indeed, laparoscopy could reduce the duration of hospitalization but also the operative morbidity and mortality. However, this surgical approach is not feasible in all situations and the conversion rate is reported in 30 to 76% of cases. One of the factors favoring the feasibility of the laparoscopic approach is the performance of early surgery. Another parameter favoring the feasibility of the laparoscopic approach is the aSBO mechanism: an aSBO on flange (SBA) is more likely to be treated effectively by laparoscopic than an aSBO on multiple adhesions (MA). In the literature, there is little to differentiate SBAs from MAs. Advances in CT scans have made it possible to describe the signs associated with the SBA mechanism and then to propose a score making it possible to predict the SBA mechanism with good performance (sensitivity 67.6%, specificity 84.6%). This score not only has the advantage of predicting the mechanism of the occlusion but it also makes it possible to predict the failure of non-surgical treatment if the score is ≥5.

The purpose of this study is to compare IV Acetaminophen for pain control to the usual care with opioids in patients admitted for small bowel obstruction.

Infections after elective intestinal surgery remain a significant burden for patients and for the health care system. The cost of treating a single surgical site infection is estimated at approximately $27,000. In adult patients, there is good evidence that the combination of oral antibiotics and mechanical bowel preparation is effective at reducing infections after intestinal surgery. In children, the body of evidence is much weaker. In this population, little evidence exists for oral antibiotics reducing infections and no data exists as to the effect of combining antibiotics with mechanical bowel preparation (such as polyethylene glycol (PEG)). The goal of the proposed study is to examine the effects of oral antibiotics with and without the combined use of mechanical bowel preparation on the rate of post-operative infectious complications in children aged 6 months to 18 years. This will be compared to the institution's current standard of care, which is to abstain from any type of mechanical bowel preparations or oral antibiotic administration before intestinal surgery.

The aim of this study is to investigate the effect of early, supplementary parenteral nutrition following emergency laparotomy. Currently, parenteral nutrition is used in postoperative patients if or when oral or enteral nutrition is not feasible. However, little data exists on the optimal timing of parenteral nutrition. Oral and enteral nutrition is encouraged. Participants will randomized on the second postoperative day if their calorie intake (oral + enteral) is below 30% of the calculated requirement. Patients will be randomized to early (postoperative day 2) or postponed (postoperative day 5) start of parenteral nutrition. The combined oral + enteral + parenteral calorie target is 70-80% of the calculated requirement. Participants in the postponed group will be re-assessed on postoperative day 5, and if their calorie intake is less than 50% parenteral nutrition will be administered. The intervention will continue until oral + enteral intake is at least 70% of the calculated requirement or the participant is at his/her habitual intake.

People who undergo surgery, or develop intestinal obstruction will spend a period of time without normal bowel function. This might extend beyond the normal measures of passage of flatus or tolerance of diet. This study will take a three stage approach to develop a patient reported outcome measure for gastrointestinal recovery. Stage 1: Qualitative interviews with 20-40 patients who have undergone major abdominal surgery, or conservatively managed intestinal obstruction. These interviews will identify key themes and ideas to develop the questionnaire. Stage 2: Face validity testing of questionnaire with 20 patients, using the QQ-10 questionnaire to aid assessment. The questionnaire may be edited after this. Stage 3: 250-500 patients will be asked to complete the questionnaire following surgery or treatment for intestinal obstruction. Basic demographics will also be collated. Item reduction and scale refinement will be undertaken using this dataset. This will provide a PROM of gastrointestinal recovery which is ready for validation.

Observational, Multicenter, Post-market, Minimal risk, Prospective data collection of PillCam SB3 videos (including PillCam reports) and raw data files and optional collection of Eneteroscopy reports

It is a retrospective study. Patients, who presented with either traumatic or general surgery emergencies, undergone exploratory laparotomy, had an open abdomen management and received Direct Peritoneal Resuscitation in addition to standard resuscitation will be considered as meeting the criteria to collect the data.

This study will randomize all patients who are new to the Mayo Clinic HPN team to either standard lipid emulsion (Intralipid) or SMOFLipid.

To assess how CFTR modulators impacted upon recorded PERT use and incidence of DIOS.
