Comparing Variability in Measurement of Subcutaneous Tumors in Mice Using 3D Thermal Imaging and Calipers.

Repeatable tumor measurements are key to accurately assessing tumor growth and treatment efficacy. A preliminary study that we conducted showed that a novel 3D and thermal imaging system (3D-TI) for measuring subcutaneous tumors in rodents significantly reduced interoperator variability across 3 in vivo efficacy studies. Here we further studied this reduction in interoperator variability across a much larger dataset.

The Physiology and Pathophysiology of Gastroesophageal Reflux in Patients with Laparoscopic Adjustable Gastric Band.

Introduction: The effect of the laparoscopic adjustable gastric band (LAGB) on esophageal acid exposure and reflux is poorly understood. Optimal technique and normative values for acid exposure have not been established in this group.

Methods: High-resolution manometry (HRM) and 24-h ambulatory esophageal pH monitoring were performed in three groups: asymptomatic LAGB, symptomatic LAGB, and pre-operative reflux patients.

Assessing quality of care in oesophago-gastric cancer surgery in Australia.

Background: Outcomes of oesophago-gastric cancer are poor and highly variable between centres. It is important that complex multimodal treatments are applied optimally. Low case volumes at Australian centres mean that the analysis of crude outcomes is an inadequate assessment of overall quality of care.

Small bowel obstruction creates a closed loop in patients with a laparoscopic adjustable gastric band.

We report on two cases of small bowel obstruction in the setting of a previous laparoscopic adjustable gastric band insertion. In both cases, a closed loop obstruction was created by the band and delayed diagnosis resulted in significant morbidity. Early recognition with deflation of the adjustable gastric band and nasogastric tube insertion is paramount to managing these patients.
