Filter by:Adhesive small bowel obstruction (ASBO) is a condition that is commonly found in patients with history of abdominal surgery. The management for such condition can be controversial. In terms of conservative treatment, recent studies have shown conflicting outcomes on whether water soluble contrast would provide benefit in reducing number of patients needed for surgery. In addition, there are a limited number of literature that investigates the role of low-osmolar contrast in reducing operative need in patients diagnosed with ASBO. The objective of this study is to compare the operative rate of patient diagnosed with ASBO between patients who were treated with low osmolar water soluble contrast (Iohexol) and patients who were treated traditionally.
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.
This study protocol aims to evaluate the impact of point-of-care ultrasound (POCUS) on the diagnosis and management of small bowel obstruction (SBO) in the emergency department (ED). SBO is a potentially life-threatening condition that requires prompt diagnosis and management. Currently, the diagnosis of SBO is based on clinical evaluation and imaging tests, including plain abdominal radiography and computed tomography (CT) scan. POCUS is a bedside imaging technique that is rapid, non-invasive, repeatable, cost-effective and radiation-free, and can provide valuable information for the diagnosis and management of SBO. The primary objective of this study is to compare the time to diagnosis of SBO between patients who undergo POCUS intestinal loops examination and those who do not undergo POCUS in the ED. The secondary objectives include comparing the hospital length of stay, the rate of surgical intervention, the rate of complications, and the mortality rate between the two groups. This is a monocentric retrospective cohort study that will include all adult patients (> 18 years old) who presented to the ED with suspected SBO. The study population will be divided into two groups: the POCUS group and the non-POCUS group. The sample size calculation will be based on the assumption of a 30% reduction in the time to diagnosis of SBO in the POCUS group compared to the non-POCUS group, with a power of 80%. The results of this study may provide more robust evidence on the diagnostic accuracy and impact of POCUS for SBO in the ED.
Small bowel obstruction (SBO) and its complications are frequently seen in patients admitted through the Emergency Departments of all acute care hospitals2. There is variation in the optimal use of imaging, the appropriate timing and duration of non-operative management attempts, anti-microbial therapies, and the criteria for surgical management, which results in heterogeneity in approaches and outcomes across international clinical centers. The expected number of SBO cases in most clinical centers is predictable, enabling a suitably-sized cohort of patients to be gathered in the snapshot audit. This 'ESTES snapshot audit' -a prospective observational cohort study- has a dual purpose. Firstly, as an epidemiological study, it aims to uncover the burden of disease. Secondly, it aims to demonstrate current strategies employed to diagnose and treat these patients. These twin aims will serve to provide a 'snapshot' of current practice, but will also be hypothesis-generating while providing a rich source of patient-level data to allow further analysis of the particular clinical questions.
A prospective, multicenter, post-market, minimal risk, observational study designed to collect PillCamTM SB3 capsule endoscopy (CE) procedures and subsequent device-assisted enteroscopy (DAE) procedures data (double balloon enteroscopy (DBE), single balloon enteroscopy (SBE) and spiral enteroscopy (SE)) in medical centers in the United States (US).
Effect of implementation of the Danish Emergency Surgery (DANAKIR) support Network on post-discharge outcomes after major emergency abdominal surgery: a prospective before and-after study Background Major emergency abdominal surgery is performed in more than 5000 patients yearly in Denmark. In general, little is known about the period after the discharge of these patients besides that chronic pain, physical dysfunction, and quality of life are severely affected in up to 50% of patients at long-term follow-up. A recent study investigating unplanned readmission after major emergency abdominal surgery found that up to 50% undergo unplanned readmission within the first 180 days after discharge. Purpose The purpose of this study is to evaluate the effects of inviting patients undergoing major emergency surgery and their relatives to join a support network after discharge (the DANAKIR network). Methods This study is designed as a before- and after study. Prior to establishing the DANAKIR (Danish Emergency Surgery Network) support network, the investigators will consecutively during a one year inclusion period prospectively include all patients undergoing emergency abdominal surgery with a midline laparotomy. The inclusion period starts 1st August 2021. The investigators will register the following in the pre-implementation phase: - Postoperative day (POD) 30: Quality of life (EQ-5D-5L) (by telephone) - POD90: Quality of life (EQ-5D-5L) (by telephone), readmissions (by hospital file) - POD 180: Quality of life (EQ-5D-5L) (by telephone), readmissions (by hospital file) - Number of days at home with 90 days (by hospital file) - Number of participants with at least one readmission (by hospital file) Hereafter the investigators will establish the DANAKIR support network. The investigators plan for a six-month inclusion period with DANAKIR starting 1th of September 2022 Intervention The DANAKIR intervention will consist of: - Structured written discharge information for the participanats and relatives about expectations and precautions - Invitation to the DANAKIR monthly information meeting All patients undergoing emergency abdominal surgery and members of their family are invited to participate in at least one DANAKIR meeting. Patients and their relatives can participate in as many meetings as they wish; however, we encourage all patients to participate at least once. DANAKIR meetings The monthly meetings are a core component of the support network. One time each month, a meeting will be held at Herlev Hospital with the participation of an emergency surgeon, an emergency surgery dedicated nurse, a dietician, and a physiotherapist. Furthermore, there will be research personnel present. Each professional (surgeon, nurse, dietician, physiotherapist) will host an informative 15 minute session regarding the postoperative course after major emergency surgery. Following the presentations time for questions in plenum and private with the different experts will be held. Furthermore, there will be an opportunity for networking at the DANAKIR meeting. Each meeting is planned to last 2 hours. At the end of each meeting the patients will be asked to evaluate the meeting and content. Outcome measures The primary outcome of this study is the number of days at home within 90 days of surgery. The secondary outcomes are quality of life at 30 days, 90 days, and 180 days after surgery and the number of patients with at least one emergency readmission 90 days and 180 days from surgery. Trial size The investigators expect to include 200 patients in the before group and 200 patients in the after group. Perspectives The DANAKIR support network examines if a structure with physical network meetings is effective in regard to quality of life and preventing readmissions after major emergency surgery. The investigators hypothesize that the days at home will increase within 90 days from surgery and that quality of life will increase for both participants and their relatives by implementing a simple and obvious solution. If the DANAKIR network proves efficient it is an easily implemented solution to increase quality of life and days at home after major emergency surgery.
The etiology of bowel obstruction is usually diagnosed by imaging techniques such as MSCTE,MRE, et al, which have some disadvantages. For example, in order to obtain better image quality, MSCTE（Multi-slices spiral computed tomography enterography） and MRE（ Magnetic resonance enterography）require patients to take a large amount of intestinal contrast solution orally, while for patients with intestinal obstruction, which may further aggravate the disease. Our study team had confirmed the mid-gut TET could serve as the delivery way of contrast solution for MRE bowel preparation with better accuracy of lesion detection and lower reduction of pain in CD（Crohn's Disease） patients. In this study, contrast solution will be delivered by colonic TET placed by lower GI-endoscopy, then we will evaluate the methodology and clinical value of this kind retrograde imaging technique in patients with intestinal obstructive diseases.
Intestinal obstruction is a common clinical problem that occurs secondary to mechanical or functional obstruction of the intestine, preventing normal transit of its contents. It is a frequent cause of hospitalization and represents 15-20% of surgical admissions for acute abdominal pain . The underlying aetiology of large bowel obstructions (LBOs) is age dependent, but in adulthood, the most common cause is colonic cancer (50-60%), typically in the sigmoid. The second most common cause in adults is acute diverticulitis (involving the sigmoid colon). Together, obstructing tumors and acute diverticulitis account for 90% of all causes of LBO. Adhesions are the most common cause of small bowel obstruction (SBO) , For practical purposes, they do not tend to cause LBO.Other causes which cause symptoms that are mimic intestinal obstruction as in bowel ischemia that mainly caused by mesenteric vessels occlusion (adynamic obstruction). Computed tomography (CT) has become a mainstay in diagnosing bowel obstruction. This is because the management of obstruction has dramatically changed with a decrease in the proportion of patients who need surgery Multi Detector Computed Tomography scanners provide a huge gain in performance that can be used to reduce the scan time, reduce section collimation, or to increase scan length surgery. Diagnosis of intestinal obstruction is established by patient history and clinical findings include abdominal distension, acute abdominal pain, vomiting and inability to pass stools or flatus . The role of CT in diagnosing intestinal obstruction has been expanding by determining presence, degree, level and cause (extrinsic lesions, intrinsic lesions, intussusception, intraluminal lesions) of obstruction and in identifying any associated strangulation, and also it has an important role in diagnosing the mesenteric vessels obstruction by thrombi by injection of IV contrast media which causes adynamic bowel obstruction .
As reported in previous studies, Point-of-Care Ultrasound (POCUS) has good performance for the diagnosis of bowel obstruction even when compared with CT. This inexpensive, radiation-free tool is available in a majority of ED. It is performed at the patient's bedside with immediate results. The learning curve allows Emergency Physicians (EP) to perform this exam after a relative brief training period. The investigators aim to investigate the ability of POCUS performed before CT to exclude the diagnosis of bowel obstruction in patients admitted for abdominal pain.
This is a single-centre retrospective cohort study utilising electronic hospital records. The aim of this study is to improve care for all patients with an intestinal emergency, irrespective of whether they have surgery or not. Data will be derived from electronic patient records collected as part of routine clinical patient care on all general adult wards (excluding maternity) between 2013 and 2020. We will then identify patients who had an emergency laparotomy, and those who had a laparoscopic procedure. We aim to identify 2 further groups where treatment is non-surgical (but could be medical or interventional radiology) or where treatment is considered futile, suggesting that an early focus on end of life care might be appropriate. The primary objective is to provide mortality rates for different treatment options, and analysis of short- and long-term outcomes. The secondary endpoints are to define patient sub-groups with similar health characteristics based on clinical data and an established risk index and to use statistical analysis to predict the risk of death for each patient group and treatment option, which will allow us to identify the best care pathways for each cluster.
