SnapSBO - Small Bowel Obstruction Snapshot Audit

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.

About this study

Prospective audit of consecutive patients admitted in Emergency Department for mechanical small bowel obstruction over a 3-month period. The audit shall include unscheduled patient admissions from November 2023 until May 2024 as outlined in 'Key Study Dates'.

As this is an observational cohort audit, no change to normal patient management is required.

Primary Objective

To explore differences in patients, management and outcomes across the entire cohort to identify areas of practice variability resulting in apparent differences in outcome warranting further study. The outcomes that the study will examine are:

  • Incidence of small bowel obstruction by etiology.
  • Differences in clinical presentation.
  • Diagnostic work-up.
  • Non-operative management strategies.
  • Time to surgery and outcomes.
  • Complications related to disease and/or therapies within 60 post-operative days.
  • Length of Emergency Department and Hospital stay.
  • Re-admission within 6 months for related conditions.

Methods for identifying patients

Multiple methods may be used according to local circumstances/staffing:

  • Daily review of emergency department (non-operative) and operating room lists.
  • Daily review of team handover sheets / emergency admission lists / ward lists.
  • Review of operating room logbooks.
  • Use of electronic systems to flag any readmissions of patients identified and treated.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Adult patients (≥16 years of age) admitted for mechanical small bowel obstruction. Example etiologies which should be included:
  • Adhesions.
  • Hernias with bowel compromise (incisional/parastomal, ventral, inguinal, femoral, obturator, internal).
  • Malignancy (primary: lymphoma, carcinoid, GIST, adenocarcinoma/metastatic disease: colon, ovarian, gastric, pancreatic, melanoma and others).
  • Enteroliths/gallstones/bezoars/foreign bodies
  • Radiation.
  • Inflammation (Crohn's disease, mesenteric adenitis, appendicitis, diverticulitis, tuberculosis, actinomycosis, ascariasis).
  • Congenital (malrotation, duplication cysts).
  • Trauma (hematomas, ischemic strictures).

Exclusion criteria

  • Functional small bowel obstruction (dysmotility or adynamic ileus secondary to abdominal operations, peritonitis, trauma or medications).

Treatment and study plan

Primary outcomes

  1. Incidence of Small Bowel Obstruction, by etiology

    Time frame: 6 months

    This study aims to quantify (as an integer, n) the etiologies of small bowel obstruction (adhesions, hernias, malignancy and other causes)

  2. Time to Surgical Treatment of Small Bowel Obstruction vs Outcomes

    Time frame: 6 months

    Time (hours) from hospital admission to Surgical Treatment of Small Bowel Obstruction vs Outcomes

Secondary outcomes

  1. Complications related to operative or non-operative management of small bowel obstruction

    Time frame: 6 months from hospital admission

    Complications related to operative or non-operative management of small bowel obstruction (integer count n,%) - for example haemorrhage, wound infection, venous thromboembolism, anastomotic leak

  2. Adherence to evidence-based guidelines vs outcomes

    Time frame: 6 months from hospital admission

    Adherence to evidence-based World Society of Emergency Surgery Bologna guideline 2020 recommendations (Table 5: available here https://wjes.biomedcentral.com/articles/10.1186/s13017-018-0185-2/tables/5) vs outcomes (30-day post operative or hospital discharge survival (median days), length of hospital stay (median days), Complications related to operative or non-operative management of small bowel obstruction (integer count n,%) - for example haemorrhage, wound infection, venous thromboembolism, anastomotic leak (integer count n,%)

  3. Patient-related Outcome Metrics for Surgical vs Non-operative management

    Time frame: At first post-discharge clinic visit, anticipated within 6 months of admission

    Patient-related Outcome Metrics for Surgical vs Non-operative management, using the PROdiGI (Patient Reported Outcome Measure for GastroIntestinal Recovery) qualitative quality-of-life assessment tool specifically designed for gastro-intestinal symptoms in adult patients undergoing major abdominal surgery for indications OR patients being treated for intestinal obstruction regardless of etiology. Patients will be assisted in completing an anonymous survey where domains of gastrointestinal function are assessed using a 20-element Likert scales (with higher scores denoting worse perceived function) and a Visual Analog Scale 0-100 grading function from 0 (worst) to 100 (best).
