“…Of note, the symptoms were independent of the size of the lesion, which may add to the difficulty of diagnosis 1. The advent of two-dimensional CT scan has enabled non-invasive evaluation of the ICV and more precise diagnosis of colonic fatty lesions 15. The findings of submucosal fats should however be interpreted cautiously in conjunction with the endoscopic results and clinical symptoms, as the mere presence of submucosal fatty infiltration of the valve is considered a normal variant.…”

Ileocecal lipohyperplasia presenting as a chronic sideropenic anaemia

Ileocecal lipohyperplasia is a relatively uncommon pathological entity characterised by submucosal infiltration of adipose tissue in the ileocecal valve (ICV). The majority of patients are asymptomatic, whereas, others present with serious complications. We report a 45-year-old man who presented with recurrent episodes of melena with secondary sideropenic anaemia for 6 years. Extensive radiological and endoscopic workup failed to detect the source of bleeding. During his last admission for abdominal pain, contrast-enhanced CT scan revealed a fatty mass at the ICV. The patient underwent limited right hemicolectomy, and histology confirmed ileocecal lipohyperplasia. The patient remained well 18 months later. This case highlights the difficulties encountered by clinicians in diagnosing this unusual colonic pathology.

“…In 90% of cases the terminal ileum enters through the medial wall of the caecum, which is the dependent area in the left lateral (LL) position. It has been reported that while the patient is in the LL position, the medial wall of the caecum is dependent, and in most instances, the terminal ileum opens into this area [ 23 ]. When stool obscures this area, it becomes difficult to visualise the entire caecum.…”

IntroductionMost colonoscopies are completed in the left lateral (LL) position but in cases of suboptimal caecal preparation, changing the patient’s position to supine (S) and, if needed, to right lateral (RL) improves caecal intubation rate, mucosal visibility, and adenoma detection.AimTo determine if position change during colonoscopy facilitates optimal visualisation of the caecum.Material and methodsA total of 359 patients were grouped into three categories based on the initial caecal intubation position. After caecal intubation, caecal visibility was scored on a four-point scale depending on the number of imaginary quadrants of the caecum completely visualized – Arya Caecal Prep Score. A score of 1 or 2 was unsatisfactory, while 3 or 4 was considered satisfactory. In patients with unsatisfactory score, position was changed from LL to S and then RL and visibility was scored again.ResultsThe initial caecal intubation in the LL position was achieved in 66.8% of patients, S in 28.5%, and RL in 4.8% of patients. 84.5% (300/355) of patients had an acceptable visualisation score at the initial caecal intubation position. Of the 55 patients with unsatisfactory caecum visualisation scores in the initial intubation position, 30 (8.5%) had satisfactory scores after the first position change (95% CI: 5.77–11.84). Twenty-five (7.04%) subjects required two position changes (95% CI: 4.61–10.22%). An additional 9.3% (11/118) of adenomas were detected in caecum and ascending colon following position change.ConclusionsChanging patient position improves caecal intubation rate, mucosal visibility, and adenoma detection.

Imaging of the ileocaecal valve

Abstract: The ileocaecal valve can cause concern when it is enlarged. We define the normal and abnormal appearances of the ileocaecal valve and illustrate the importance of using CT and endoscopy to make the correct diagnosis, avoiding any further unnecessary interventions.
