Single leaflet reconstruction of pulmonic valve with decellurized bovine pericardium.

A patient presented with a complex mass seen extending from the lumen of the aorta to the lumen of the pulmonary artery. Papillary fibroelastoma was identified at resection, however the left pulmonary valve leaflet required resection to fully remove the mass. The leaflet was reconstructed using the bovine pericardial extracellular matrix.

Quality of life comparing dor and toupet after heller myotomy for achalasia.

Background: Laparoscopic Heller cardiomyotomy (LHC) is standard therapy for achalasia. Traditionally, an antireflux procedure has accompanied the myotomy. This study was undertaken to compare quality-of-life outcomes between patients undergoing myotomy with Toupet versus Dor fundoplication.

Collaborating to increase access to clinical and educational resources for surgery: a case study.

A case study is described in which collaborations between a Department of Surgery, a Department of Information Technology, and an academic health sciences library resulted in the development of an electronic surgical library available at the bedside, the deployment of tablet devices for surgery residents, and implementation of a tablet-friendly user interface for the institution's electronic medical record.

Roux-en-Y gastric bypass increases intravenous ethanol self-administration in dietary obese rats.

Roux-en-Y gastric bypass surgery (RYGB) is an effective treatment for severe obesity. Clinical studies however have reported susceptibility to increased alcohol use after RYGB, and preclinical studies have shown increased alcohol intake in obese rats after RYGB. This could reflect a direct enhancement of alcohol's rewarding effects in the brain or an indirect effect due to increased alcohol absorption after RGYB.

An intestinal occlusion device for prevention of small bowel distention during transgastric natural orifice transluminal endoscopic surgery.

Background And Objectives: Bowel distention from luminal gas insufflation reduces the peritoneal operative domain during natural orifice transluminal endoscopic surgery (NOTES) procedures, increases the risk for iatrogenic injury, and leads to postoperative patient discomfort.

Methods: A prototype duodenal occlusion device was placed in the duodenum before NOTES in 28 female pigs. The occlusion balloon was inflated and left in place during the procedure, and small bowel distension was subjectively graded.

Sleep deprivation increases cognitive workload during simulated surgical tasks.

Background: There have been conflicting reports of the effects of modest sleep deprivation on surgical skills. The aim of this study was to assess the effects of a 24-hour call shift on technical and cognitive function, as well as the ability to learning a new skill.

Methods: Thirty-one students trained to expert proficiency on a virtual reality part-task trainer.

Reliability of gastric access closure with the self-approximating transluminal access technique (STAT) for NOTES.

Background: STAT, or the self-approximating transluminal access technique, has been previously described and involves the dissection of a submucosal tunnel for peritoneal or mediastinal access from the esophagus and stomach. The objective of this study was to assess the safety and reliability of gastric access and closure in a porcine experience using STAT for natural orifice transluminal endoscopic surgery (NOTES).

Methods: A review of the experience using STAT access tunnels for intraperitoneal access was performed in 39 female pigs at a university animal lab.

Multiply recurrent episodes of gastric emphysema.

Introduction. Gastric emphysema can present both a diagnostic challenge and a life-threatening condition for patients and has only once been reported as being recurrent. Background.
