Introduction Adhesive small bowel obstruction (ASBO) is a common cause of admissions to general surgery services. Water-soluble contrast (WSC), such as Gastrografin® (GGF), can be utilised in the conservative management of patients with ASBO, with predictive and possible therapeutic value. We audited the non-operative management of ASBO in the general surgery department of East and North Hertfordshire NHS Trust, a district general hospital. Following the introduction of a hospital-wide protocol standardising the use of GGF in patients with ASBO, a re-audit was conducted to assess its impact. Methods A retrospective audit of ASBO patients who received GGF was conducted in two cycles: before and after the implementation of the protocol. Data were collected between February and June 2022 for group 1 (pre-protocol) and between August and November 2023 for group 2 (post-protocol). Results Forty-eight patients were included in the analysis across both groups: 31 in group 1 (pre-protocol) and 17 in group 2 (post-protocol). The success rate of this non-operative trial with GGF increased from 77% (24/31) in group 1 to 88% (15/17) in group 2. The median duration of conservative management was two days in both groups. The median time from CT scan to GGF administration decreased from 24 hours in group 1 to 19 hours 22 minutes in group 2, and the interval between GGF administration and first abdominal radiograph decreased from 9 hours in group 1 to 6 hours 25 minutes in group 2. Conclusion Our closed-loop audit suggests that by streamlining the non-operative management pathway of adhesive small bowel obstruction, our standardised protocol is safe and possibly improves efficiency within a district general hospital setting.

Small bowel internal hernias (IHs), a rare cause of small bowel occlusion (SBO) and small bowel strangulation, while more commonly seen in young adults, can also affect elderly patients and pose a significant diagnostic challenge due to their nonspecific symptoms. In most cases, laparotomy was used to diagnose IHs. However, multidetector computed tomography (MDCT) is usually the best imaging tool to use in the emergency setting for the diagnosis of IHs. An 83-year-old man was admitted to emergency with acute abdominal pain and a coffee-ground vomitus. The abdominal MDCT showed a clustered-like appearance of proximal jejunal loops at the level of the Treitz ligament with the absence of transit of the medium water-soluble iodine oral contrast agent (Gastrografin). Mesenteric edema was also present with initial suffering of the intestinal wall. A left paraduodenal hernia (LPDH) with strangulation was suspected following the radiological report. The emergency laparotomy revealed about 20 cm of proximal jejunal loops herniated through a 3 cm wide hernia orifice (HO) along the Treitz ligament, at the level of Landzert fossa, located in the confluence of the descending mesocolon, posterior to the inferior mesenteric vein (IMV) and confirming the LPDH. The patient was discharged in good condition some days later. IHs do not have sufficient coverage in literature, especially in cases regarding elderly patients, however, they can be a cause of SBO in people older than 80 years of age. Radiologists and surgeons should be aware of the anatomical aspects of the IHs.
