Gastric outlet obstruction

Published in David A Lisle, Imaging for Students, 2012

Hypertrophic pyloric stenosis refers to progressive gastric outlet obstruction due to idiopathic hypertrophy of the circular muscle fibres of the pylorus. Clinical presentation is usually at around 6 weeks of age, with forceful non-bile stained vomiting leading to dehydration and hypokalaemic alkalosis. Palpation of a pyloric muscular mass in the right upper quadrant of an infant with a typical clinical history is diagnostic of hypertrophic pyloric stenosis and imaging is not required in such cases.

Krishnan et al., in a single center retrospective trial, reported the outcomes of 37 patients who underwent endoscopic stenting for management of anastomotic leak post bariatric surgery. The incidence of stent migration without anchoring was 41.18% versus 15% only with OverStitchTM stent anchoring [29]. There are multiple case reports demonstrating OverStitchTM success in stent fixation in the esophagus and stomach for uncommon indications such as relieving malignant gastric outlet obstruction with a stent-within-stent approach with OverStitchTM fixation [30]. Figure 5 shows esophageal stent fixation using OverStitchTM device.
