Randomized Controlled Trial
Tumour regression in the randomized Stockholm III Trial of radiotherapy regimens for rectal cancer.
The Stockholm III Trial randomized patients with primary operable rectal cancers to either short-course radiotherapy (RT) with immediate surgery (SRT), short-course RT with surgery delayed 4-8 weeks (SRT-delay) or long-course RT with surgery delayed 4-8 weeks. This preplanned interim analysis examined the pathological outcome of delaying surgery. ⋯ Short-course RT induces tumour downstaging if surgery is performed after an interval of 4-8 weeks.

Surgeons provide patients with information before surgery, although standards of information are lacking and practice varies. The development and use of a 'core information set' as baseline information before surgery may improve understanding. A core set is a minimum set of information to use in all consultations before a specific procedure. This study developed a core information set for oesophageal cancer surgery. ⋯ This study has established a core information set for surgery for oesophageal cancer.

Observational Study
Surgical treatment of gastrointestinal stromal tumour of the rectum in the era of imatinib.
Gastrointestinal stromal tumours (GISTs) of the rectum often require radical surgery to achieve complete resection. This study investigated the management and outcome of surgery for rectal GISTs and the role of imatinib. ⋯ The use of neoadjuvant imatinib for rectal GISTs significantly decreased both tumour size and mitotic activity, which permitted less radical sphincter-preserving surgery.

Non-operative management may be an alternative for uncomplicated appendicitis, but preoperative distinction between uncomplicated and complicated disease is challenging. This study aimed to develop a scoring system based on clinical and imaging features to distinguish uncomplicated from complicated appendicitis. ⋯ With use of novel scoring systems combining clinical and imaging features, 95 per cent of the patients deemed to have uncomplicated appendicitis were correctly identified as such. The score can aid in selection for non-operative management in clinical trials.

A precise estimation of the capacity of the remnant liver following partial liver resection is important. In this study, the regional function of the liver in patients undergoing living-donor liver transplantation was evaluated by gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid (EOB)-enhanced MRI, with special reference to the congested region. ⋯ The function of the congested region secondary to outflow obstruction in the remnant donor liver was approximately 70 per cent of that in the non-congested region. EOB-MRI is a promising tool to assess regional liver function, with good spatial resolution.
