Two forms of tibial nerve stimulation are used to treat faecal incontinence (FI): percutaneous (PTNS) and transcutaneous (TTNS) tibial nerve stimulation. This article critically appraises the literature on both procedures. ⋯ PTNS and TTNS result in significant improvements in some outcome measures; however, TTNS was not superior to sham stimulation in a large, adequately powered, RCT. As no adequate RCT of PTNS versus sham has been conducted, conclusions cannot be drawn regarding this treatment.

Randomized Controlled Trial Comparative Study
Randomized clinical trial of selective versus routine preoperative duplex ultrasound imaging before arteriovenous fistula surgery.
Anatomical suitability for arteriovenous fistula (AVF) formation was formerly determined by clinical examination alone. There are potential benefits from imaging to assess anatomical suitability. Existing studies examined the role of routine preoperative ultrasonography versus clinical examination alone. The role of a selective duplex ultrasound imaging policy is unknown. This study aimed to compare a policy of selective versus routine ultrasound assessment before AVF formation. ⋯ NCT01004627 (http://www.clinicaltrials.gov).

Multidisciplinary discussion of the treatment of patients with colorectal liver metastases (CRLM) is advocated currently. The aim of this study was to investigate medical oncologists' and surgeons' assessment of resectability and indication for chemotherapy, and the effect of an educational intervention on such assessment. ⋯ Resectability and indication for preoperative chemotherapy were assessed differently by medical oncologists and surgeons. The educational intervention resulted in more patients deemed resectable by both oncologists and surgeons, and less frequent indication for chemotherapy.

Comparative Study
Propensity score analysis of oesophageal cancer treatment with surgery or definitive chemoradiotherapy.
The role of treatments involving surgery versus definitive chemoradiotherapy (dCRT) for oesophageal cancer remains controversial. ⋯ There was no difference in survival after oesophageal cancer treatment involving surgery or dCRT.

Retrorectal tumours present diagnostic and surgical challenges. This study aimed to identify whether preoperative imaging and/or biopsy provide diagnostic accuracy. ⋯ Preoperative imaging was accurate in the assessment of retrorectal tumours, whereas biopsy did not add to the surgical strategy.
