Transcaval Coil Embolization of Type 2 Endoleak After Endovascular Aortic Repair: An Institutional Review.

Objectives: Endovascular aortic repair may be complicated by type 2 endoleaks. Intervention is generally recommended when the native sac continues to grow more than 5 mm. Transcaval coil embolization (TCE) of the native aneurysm sac is an emerging technique for repair of type 2 endoleaks.

Endovascular Repair of Transected Axillary Artery via Snare Assisted Through and Through Femoral to Brachial Artery Access.

Axillary artery injury is a rare but complex surgical problem that often requires challenging exposures, lengthy operations, and morbid outcomes for repair. For these reasons, endovascular repair is an attractive alternative as it obviates many of the challenges present with open repair. While pseudoaneurysms, dissections, and short segment injuries with limited arterial disruption are regularly treated endovascularly, complete arterial transections are almost exclusively treated with open repair as obtaining wire access across the site of injury is often not possible.

A Review of "Options in Management of Trauma to the Esophagus" (1982) "Submitted for the Literary Festschrift in Honor of J. David Richardson, MD".

This article is an update of a paper which Dave Richardson and I published in 1982, and serves as both an update of management of esophageal injuries and as a lasting tribute to my mentor and hero J. David Richardson.

Comparative Efficacy of Bilateral Thoracoscopic Splanchnicectomy for Intractable Pain Secondary to Pancreatic Cancer vs Chronic Pancreatitis.

Background: Splanchnicectomy has been evaluated for treatment of chronic pain in both pancreatic cancer and chronic pancreatitis patients, although its efficacy has not been compared in these 2 patient populations. This study aimed to compare bilateral thoracoscopic splanchnicectomy in treatment of abdominal pain secondary with pancreatic cancer and chronic pancreatitis.

Study Design: A University of Louisville database was evaluated from July 1998 to March 2016 for patients undergoing bilateral thoracoscopic splanchnicectomy for intractable pain secondary to pancreatic cancer (n = 48) or chronic pancreatitis (n = 75).

Cholinergic signaling in the gut: a novel mechanism of barrier protection through activation of enteric glia cells.

Background: Enteric glia cells (EGCs) play an important role in maintaining proper intestinal barrier function. We have shown that vagal nerve stimulation (VNS) increases EGC activation, which is associated with better gut barrier integrity. Enteric neurons communicate with EGCs through nicotinic cholinergic signaling, which may represent a pathway by which VNS activates EGCs.

Enteric glia cells attenuate cytomix-induced intestinal epithelial barrier breakdown.

Background: Intestinal barrier failure may lead to systemic inflammation and distant organ injury in patients following severe injury. Enteric glia cells (EGCs) have been shown to play an important role in maintaining gut barrier integrity through secretion of S-Nitrosoglutathione (GSNO). We have recently shown than Vagal Nerve Stimulation (VNS) increases EGC activation, which was associated with improved gut barrier integrity.

Targeting α-7 nicotinic acetylcholine receptor in the enteric nervous system: a cholinergic agonist prevents gut barrier failure after severe burn injury.

We have previously shown that vagal nerve stimulation prevents intestinal barrier loss in a model of severe burn injury in which injury was associated with decreased expression and altered localization of intestinal tight junction proteins. α-7 Nicotinic acetylcholine receptor (α-7 nAchR) has been shown to be necessary for the vagus nerve to modulate the systemic inflammatory response, but the role of α-7 nAchR in mediating gut protection remained unknown. We hypothesized that α-7 nAchR would be present in the gastrointestinal tract and that treatment with a pharmacological agonist of α-7 nAchR would protect against burn-induced gut barrier injury.
