The sigmoid take-off: An anatomical imaging definition of the rectum validated on specimen analysis.

Background: A pre-operative imaging landmark to define the rectum would optimise clinical care of rectal cancer patients and research efforts to improve outcomes. The sigmoid take-off has been suggested as an imaging landmark for the rectosigmoid junction (RSJ). This study aimed to investigate whether this imaging definition of the rectum was validated by surgical specimen analysis.

A very persistent chicken bone: two separate perforations from the same foreign object 2 months apart.

A 56-year-old man presented acutely with abdominal pain and raised inflammatory markers. Initial CT images demonstrated acute inflammation in the right upper quadrant surrounding a high-density linear structure. The appearance was of a chicken bone causing a contained small bowel perforation.

Treatment of recurrent sigmoid volvulus in Parkinson's disease by percutaneous endoscopic colostomy.

The exact aetiology of sigmoid volvulus in Parkinson's disease (PD) remains unclear. A multiplicity of factors may give rise to decreased gastrointestinal function in PD patients. Early recognition and treatment of constipation in PD patients may alter complications like sigmoid volvulus.

Surgical treatment in familial adenomatous polyposis.

Familial adenomatous polyposis (FAP) is a dominantly inherited condition caused by germline mutation of the gene resulting in formation of numerous large bowel adenomas in late childhood or adolescence. Unless these are removed, colorectal cancer inevitably develops. Prophylactic surgical treatment is required to prevent this.

Isolated Gallbladder Injury after Blunt Abdominal Trauma: a Case Report and Review.

We describe a case of isolated gallbladder contusion after deceleration trauma. On admission, no evident signs of intra-abdominal injury were present. However, after 24 h observation an explorative laparotomy was performed because of persistent abdominal complaints.
