Post-surgical adhesions occur in up to 90% of abdominal surgeries, often leading to complications like adhesive small bowel obstruction (ASBO) and chronic pain. They result from imbalanced healing processes influenced by growth factors, fibroblast activity, and genetic predispositions. While surgery can relieve ASBO, it frequently causes new adhesions, with recurrence rates up to 40%. Anti-adhesion barriers, such as the starch-based 4DryField® PH, form a temporary gel barrier to support healing. Though promising, its role in preventing ASBO recurrence is not well studied. This study evaluates whether intra-operative use of 4DryField® PH reduces ASBO recurrence over 12 months and compares perioperative outcomes in treated vs. untreated patients.

NCT06777446
Rationale: Adhesive small bowel obstruction (aSBO) is a frequent surgical emergency, associated with 3-8% hospital mortality and a high risk of recurrence (20% at two years of follow-up). ASBO can be treated conservatively or by emergency surgery. In the absence of bowel ischemia or strangulation, conservative treatment is often preferred, to avoid the excess morbidity and mortality from emergency surgery. Recent epidemiological studies, however, demonstrate a considerable higher recurrence risk of aSBO after conservative treatment that is associated with hospital readmissions and lower survival. Elective adhesiolysis following successful conservative treatment might reduce these long-term risks whilst avoiding the high complication rate of emergency surgery. Objective: The investigators aim to assess the efficacy of elective adhesiolysis following conservative treatment for aSBO as compared to the current state of the art (wait-and-see policy) to prevent long-term recurrence of aSBO. Further the investigators will evaluate quality of life, healthcare and societal costs. Study design: Multicenter open-label randomized controlled trial, including 380 patients. Study population: Adult patients who recovered from aSBO by conservative treatment. Patients that are inoperable for medical, anaesthesiological or surgical reasons are excluded. Intervention (if applicable): The intervention of investigation is elective adhesiolysis. Adhesiolysis is an abdominal procedure in which all adhesions are cut, and adhesion prevention applied to reduce the risk of adhesion reformation. The intervention is compared to wait-and-see policy (the current standard treatment) Main study parameters/endpoints: Primary outcome is recurrence, defined as readmission for obstructive systems with aetiology of adhesions confirmed by CT. The investigators hypothesize a 50% reduction in recurrence in the intervention arm. Secondary outcomes are morbidity from surgery, health-related quality of life (EQ5D), healthcare costs and societal costs (iMCQ and iPCQ) Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Patients in the intervention group are exposed to abdominal surgery, which is associated with a moderate risk of minor complications such as wound infection and haemorrhage, and a small risk of severe complications such as iatrogenic bowel injury. According to our hypothesis, a potential benefit is the reduction in the risk of recurrences. Recurrence of aSBO is associated with a risk of readmissions, reinterventions, and also increased long-term mortality.

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.

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.

Small bowel obstruction (SBO) occurs when the normal movements of the small bowel is obstructed, most commonly due to adhesion related to previous abdominal surgery. This may cause strangulation of the small bowel with reduced blood flow which is a surgical emergency requiring prompt treatment in the operating room. If there are no signs of strangulation or ischemia of the bowel at the time of diagnosis, international guidelines recommend initial treatment with intravenous fluids and nasogastric tube placement. However, there is emerging debate regarding non-selective treatment with nasogastric tube placement in patients with SBO. This management started around 1930 as a means to reduce pain in patients with SBO, in conjunction with other additions to management, like intravenous fluids. However the effect and utility of routine nasogastric tube placement have not been prospectively evaluated. There are a total of three retrospective observational studies in the past decade with a total of 759 patients where 292 (36%) were managed without a nasogastric tube. There was no difference in the rates of conservative treatment failure (requiring surgery), complications (vomiting, pneumonia) or mortality between patients receiving a nasogastric tube and those who didn't. However, the retrospective design of these studies limits their validity. Furthermore, nasogastric tube placement has been shown to be one of the more painful interventions patients may experience in-hospital. This calls into question the patient benefit of routine nasogastric tube placement in patients with SBO and further studies are needed to discern the utility of this intervention. Definitive treatment for SBO is surgical adhesiolysis but there is debate regarding the timing of surgery, particularly in older adults. A large proportion of patients may be managed conservatively with oral contrast and repeated radiological evaluation and the obstruction will resolve in many patients within 24 to 48 hours. This timeframe is dependent on factors related to the disease itself as well as patient related factors like previous surgery and comorbidities. Older patients are at high risk for complications but current available data is insufficient to inform practice in this population. Frailty, a state of increased vulnerability and susceptibility to adverse events, has been shown to be an independent prognosticator in older adults in the Emergency Department(ED) and suggested as a potential measure to risk stratify older adults with SBO. However to the authors knowledge there is no available data on frailty in older adults with SBO and only one prospective observational trial looking at older adults with SBO. Despite SBO being one of the most common surgical emergencies in older adults. To investigate the potential benefit of nasogastric tube placement in patients with SBO and the ability of frailty to prognosticate outcomes in older adults better evidence is needed.
