Transanal endoscopic surgery: past, present and future.

Transanal endoscopic surgery is a safe, established technique to remove lesions in the rectum via the anus. This article reviews its evolution, approaches, indications and evidence for its role in treating benign rectal polyps. The future of transanal endoscopic surgery in rectal cancer and inflammatory bowel disease is also explored.

Combining enteral with parenteral nutrition to improve postoperative glucose control.

The provision of parenteral nutrition (PN) to 'stressed' patients often results in hyperglycaemia, which may be detrimental. In animal models limited amounts of enteral nutrition (EN) improve intestinal integrity and stimulate intestinal incretin production, which may lead to improved glucose control. We set out to assess if combining EN with PN results in improved glucose homeostasis rather than PN given alone.

Systematic review of postdischarge oral nutritional supplementation in patients undergoing GI surgery.

Objective: To determine whether nutritional supplementation following hospital discharge in patients who undergo gastrointestinal (GI) surgery is beneficial in specific outcome measures.

Methods: A systematic review was conducted of randomized controlled trials comparing nutritional supplements vs a "standard care" regimen given to patients following discharge from hospital after GI surgery. Outcome measures were weight change, quality of life, clinical complications, fatigue, and hand grip strength.

Rectal cancer: the role of radiotherapy.

Surgery is the definitive tool in the management of patients with rectal carcinoma. Early failure of treatment remains problematic and is manifest in local recurrence. Development of surgical techniques and inclusion of other treatment modalities aim to reduce the incidence of local recurrence and improve survival.

Perioperative and postoperative nutrition.

Nutritional deficiency among hospitalized patients is common, and is often unrecognized and untreated. Perioperative starvation is detrimental to recovery. Nutritional support can reduce morbidity, mortality and length of hospital stay.
