Predicting blood transfusion in patients undergoing minimally invasive oesophagectomy.

Aim: To evaluate predictors of allogenic blood transfusion requirements in patients undergoing minimal invasive oesophagectomy at a tertiary high volume centre for oesophago-gastric surgery.

Methods: Retrospective analysis of all patients undergoing minimal access oesophagectomy in our department between January 2010 and December 2011. Patients were divided into two groups depending on whether they required a blood transfusion at any time during their index admission.

The feasibility of a randomized controlled trial of esophagectomy for esophageal cancer--the ROMIO (Randomized Oesophagectomy: Minimally Invasive or Open) study: protocol for a randomized controlled trial.

Background: There is a need for evidence of the clinical effectiveness of minimally invasive surgery for the treatment of esophageal cancer, but randomized controlled trials in surgery are often difficult to conduct. The ROMIO (Randomized Open or Minimally Invasive Oesophagectomy) study will establish the feasibility of a main trial which will examine the clinical and cost-effectiveness of minimally invasive and open surgical procedures for the treatment of esophageal cancer.

Methods/design: A pilot randomized controlled trial (RCT), in two centers (University Hospitals Bristol NHS Foundation Trust and Plymouth Hospitals NHS Trust) will examine numbers of incident and eligible patients who consent to participate in the ROMIO study.

Bravo catheter-free pH monitoring: normal values, concordance, optimal diagnostic thresholds, and accuracy.

Background & Aims: The Bravo pH capsule is a catheter-free intraesophageal pH monitoring system that avoids the discomfort of an indwelling catheter. The objectives of this study were as follows: (1) to obtain normal values for the first and second 24-hour recording periods using a Bravo capsule placed transnasally 5 cm above the upper border of the lower esophageal sphincter determined by manometry and to assess concordance between the 2 periods, (2) to determine the optimal discriminating threshold for identifying patients with gastroesophageal reflux disease (GERD), and (3) to validate this threshold and to identify the recording period with the greatest accuracy.

Methods: Normal values for a manometrically positioned, transnasally inserted Bravo capsule were determined in 50 asymptomatic subjects.

Ambulatory 24-hour esophageal pH monitoring: why, when, and what to do.

The incidence of gastroesophageal reflux disease (GERD) is increasing and if left untreated can lead to significant patient morbidity and even death. The disease results from the abnormal reflux of gastric contents into the distal esophagus causing symptoms in most and subsequent mucosal damage in some. Several investigations can be used to confirm the diagnosis, but most are dependent on the presence of sequelae and complications of the disease.

Excellent quality of life after Nissen fundoplication depends on successful elimination of reflux symptoms and not the invasiveness of the surgical approach.

Background: Quality of life, poor in patients with reflux disease, improves significantly after an antireflux operation. The aim of this study was to determine the relative importance of the operative approach used for a fundoplication, as well as the successful elimination of reflux symptoms on long-term quality of life in patients with gastroesophageal reflux disease.

Methods: A questionnaire, including the medical outcome study short-form health survey (SF-36), was completed by 105 patients who had undergone either a laparoscopic Nissen fundoplication (n = 72) or a transthoracic Nissen fundoplication (n = 33); median follow-up was 25 and 31 months, respectively.
