ABSTRACT
Ileal pouch-related adenocarcinoma remains a rarity; thus, guidelines on treatment are currently lacking. We present this case of a 54-year-old man who underwent restorative proctocolectomy with stapled ileal pouch-anal anastomosis formation for familial adenomatous polyposis during the 1980s. Despite undergoing annual surveillance endoscopy, the patient was noted to be anaemic and passing fresh blood per anus Endoscopy and radiological investigation revealed the presence of a pouch-related adenocarcinoma. This was subsequently treated with short-course radiotherapy and pouch excision. The patient remains well until now and will follow six-monthly surveillance protocols with a transition to annual surveillance after 2â years.

OBJECTIVE: The human mesentery is now regarded as contiguous from the duodenojejunal (DJ) to anorectal level. This interpretation prompts re-appraisal of computed tomography (CT) images of the mesentery. METHODS: A digital model and reference atlas of the mesentery were generated using the full-colour data set of the Visible Human Project (VHP). Seventy one normal abdominal CT images were examined to identify mesenteric regions. CT appearances were correlated with cadaveric and histological appearances at corresponding levels. RESULTS: Ascending, descending and sigmoid mesocolons were identifiable in 75%, 86% and 88% of the CTs, respectively. Flexural contiguity was evident in 66%, 68%, 71% and 80% for the ileocaecal, hepatic, splenic and rectosigmoid flexures, respectively. A posterior mesocolic boundary corresponding to the anterior renal fascia was evident in 40% and 54% of cases on the right and left, respectively. The anterior pararenal space (in front of the boundary) corresponded to the mesocolon. CONCLUSIONS: Using the VHP, a mesenteric digital model and reference atlas were developed. This enabled re-appraisal of CT images of the mesentery, in which contiguous flexural and non-flexural mesenteric regions were repeatedly identifiable. The anterior pararenal space corresponded to the mesocolon. KEY POINTS: The Visible Human Project (VHP) allows direct identification of mesenteric structures. Correlating CT and VHP allows identification of flexural and non-flexural mesenteric components. Radiologic appearance of intraperitoneal structures is assessed, starting from a mesenteric platform.

INTRODUCTION: Small bowel obstruction is a common world-wide condition that has a range of etiological factors. The management is largely dependent on the cause of the obstruction. Small bowel obstruction caused by foreign body ingestion is rare; many items have been reported as responsible, but there are no reports implicating polyurethane foam. CASE PRESENTATION: We report the case of a 44-year-old Irish male who presented following ingestion of polyurethane foam. He was asymptomatic on presentation but developed a small bowel obstruction shortly thereafter. CONCLUSION: Patients presenting following ingestion of polyurethane foam should be scheduled for elective laparotomy, gastrotomy, and retrieval of the cast on the next available theatre list - given that they are suitable for surgery.
ABSTRACT
A 16-year-old female presented with acute-onset abdominal pain and an initial diagnosis of midcycle pain. Subsequent pelvic ultrasound and diagnostic laparoscopy showed a large mass in the pouch of Douglas. The patient underwent a laparotomy and excision of a mass from a loop of jejunum. This case highlights the difficulties in diagnostic differentiation relating to large pelvic masses in young females.
