National Snapshot Study Adhesive Small Bowel Obstruction (ASBO)

Study Overview
=================
Brief Summary
-----------------
Over 63-90% of patients develop peritoneal adhesions after abdominal or pelvic surgery. Which makes it the most common complication after abdominal or pelvic surgery. Adhesions comprise a lifelong risk of adhesion related complications.The most frequent emergency complication of adhesion is an episode of adhesive small bowel obstruction (ASBO). Over 1 in 5 patients experiences at least 1 episode of ASBO in the 10 years following initial abdominal surgery. Despite the high incidence of ASBO, diagnosis and treatment of an episode of ASBO varies greatly between hospitals and even between doctors. Until now, optimal treatment patterns are unknown. The aim of this study is mapping of care for patients with a suspected episode of ASBO. With the collected data new hypothesis will be generated for the ideal diagnostic and therapeutic workflow for patients with a suspicion of an episode of ASBO.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| CT treatment ASBO | In how many patients does CT-scan impact initial management of ASBO (i.e. different cause of SBO found, or conservative trial vs. direct surgery)? | February 2021 | 
| Diagnostics ASBO | How many patients in the Netherlands presenting with adhesive small bowel obstruction have a CT-scan in their diagnostic work-up? | February 2021 | 
| Timeframe conservative trial ASBO | How long do Dutch surgeons continue a conservative trial in patients with persistent obstruction who are not clinically deteriorating? Outcome measures will be based on data from the online Case Report Form (CRF). | February 2021 | 
| Conservative trial > 72 hours ASBO | Does continuing a conservative trial for more than 72 hours adverse impact final outcomes? Complications as measured by Clavien-Dindo will be registered and compared between groups. | February 2021 | 
| Laparoscopic surgery for ASBO | How many patients that are surgically treated for ASBO in the Netherlands have laparoscopic surgery? | February 2021 | 
| Outcome laparoscopic surgery for ASBO | What are the outcomes of laparoscopic surgery for ASBO? Days of in hospital stay, postoperative complications (Clavien-Dindo) and 90-day readmissions rates will be compared between patients who underwent open or laparoscopic surgery for ASBO. | February 2021 |
