Validity of the ActiReg system and a physical activity interview in assessing total energy expenditure in long-term survivors after total gastrectomy.

Background & Aims: Malnutrition is common after total gastrectomy. There is a need for clinically useful methods to assess energy requirements. We aimed to validate measurements of energy expenditure by an activity monitor (ActiReg) and a physical activity interview (HPAQ(modified)), in long-term survivors after gastrectomy for gastric carcinoma, using doubly labelled water as reference method.

Effects of nutritional support long time after total gastrectomy.

Background & Aims: Long-term effects of total gastrectomy on nutritional status are not well known, neither is the role of nutritional support. Dietary counselling is usually individualized, but generally not well defined. We aimed to evaluate effects of individualized oral nutritional support long time after total gastrectomy.

Impact of endoscopic ultrasonography (EUS) on surgical decision-making in upper gastrointestinal tract cancer: an international multicenter study.

Background: Endoscopic ultrasonography (EUS) is an integrated part of the pretherapeutic evaluation program for patients with upper gastrointestinal (GI) tract cancer. Whether the clinical impact of EUS differs between surgeons from different countries is unknown. The same applies to the potential clinical influence of EUS misinterpretations.

Changes of gastric mucosal architecture during long-term omeprazole therapy: results of a randomized clinical trial.

Background: The impact of long-term acid suppression on the gastric mucosa remains controversial.

Aim: To report further observations on an established cohort of patients with gastro-oesophageal reflux disease, after 7 years of follow-up.

Methods: Of the original cohort randomized to either antireflux surgery or omeprazole, 117 and 98 patients remained in the medical and surgical arms, respectively.

Sealing of esophageal perforation or ruptures with expandable metallic stents: a prospective controlled study on treatment efficacy and limitations.

Esophageal perforations are surgical emergencies with high mortality rates. A variety of treatment strategies have been advocated. No single strategy has however, been fully applicable to deal with most situations.
