Sacral neuromodulation (SNM) is a widely adopted treatment for overactive bladder, non-obstructive urinary retention and faecal incontinence. In the majority, it provides sustained clinical benefit. However, it is recognized that, even for these patients, stimulation parameters (such as amplitude, electrode configuration, frequency and pulse width) may vary at both initial device programming and at reprogramming, the latter often being required to optimize effectiveness. Although some recommendations exist for SNM programming, the scientific data to support them are understood by few clinicians. ⋯ Knowledge of the science of neuromodulation provides some guiding principles for programming but these are broad. These principles are not refuted by preclinical data but specific parameters in clinical use are not strongly supported by animal data, even after the limitations of small and large animal models are considered. The review presents a shortlist of programming principles on a theoretical basis but acknowledges that current practice is as much derived from evolved experience as science.

Observational Study
A colorectal straight-to-test cancer pathway with general-practitioner-guided triage improves attainment of the 28-day diagnosis target and increases outpatient clinic capacity.
This study investigates whether a straight-to-test (STT) colorectal cancer pathway improves attainment of the National Health Service (NHS) England 28-day Faster Diagnosis Standard and the effect of the pathway on reducing face-to-face outpatient clinic appointments. Patient satisfaction and the safety of a novel general practitioner (GP) led patient triage system regarding suitability for colonoscopy are also evaluated. ⋯ An STT pathway for suspected colorectal cancer referrals with novel GP-led patient triage safely streamlines patients through the suspected colorectal cancer diagnostic pathway and significantly reduces requirement for face-to-face outpatient clinic attendance. This is achieved with high patient satisfaction.

Acute diverticulitis (AD) is commonly diagnosed in outpatient and emergency departments and is associated with severe complications such as perforation and fistula. Symptoms of irritable bowel syndrome (IBS), such as abdominal pain, constipation and diarrhoea, are also common with AD. This study aimed to evaluate the strength of a possible association between IBS and AD. ⋯ The epidemiological evidence in this study demonstrates that patients with IBS are associated with a higher incidence of AD and also its recurrence.

Aspiration is a common cause of pneumonia in patients with postoperative ileus. Insertion of a nasogastric tube (NGT) is often performed, but this can be distressing. The aim of this study was to determine whether the timing of NGT insertion after surgery (before versus after vomiting) was associated with reduced rates of pneumonia in patients undergoing elective colorectal surgery. ⋯ In patients who required the insertion of a NGT after surgery, prophylactic insertion was not associated with fewer cases of pneumonia within 30 days of surgery compared with reactive insertion.
