Surgical management of Zollinger-Ellison syndrome (ZES) relies on localization and resection of all tumor foci. We describe the benefit of combined intraoperative use of a portable large field of view gamma camera (LFOVGC) and a handheld gamma detection probe (HGDP) for indium-111 ((111)In)-pentetreotide radioguided localization and confirmation of gastrinoma resection in ZES. ⋯ Real-time LFOVGC imaging and HGDP use for surgical management of gastrinoma improve success of localizing and resecting all neuroendocrine tumor-positive tumor foci, providing instantaneous navigational feedback. This approach holds potential for improving long-term patient outcomes in patients with ZES.

Liver transplantation centers are unevenly distributed within the Donor Service Areas (DSAs) of the United States. This study assessed how market competition and liver transplantation center density are associated with liver transplantation volume within individual DSAs. ⋯ After controlling for demographic and market factors, a greater concentration of centers was associated with more liver transplants without impacting overall survival. These results warrant additional investigation into the relationship between geospatial factors and liver transplantation volume with consideration for the optimization of scarce resources.

Randomized Controlled Trial Comparative Study
Repair of Paraesophageal Hiatal Hernias-Is a Fundoplication Needed? A Randomized Controlled Pilot Trial.
The need for a fundoplication during repair of paraesophageal hiatal hernias (PEH) remains unclear. Prevention of gastroesophageal reflux represents a trade-off against the risk of fundoplication-related side effects. The aim of this trial was to compare laparoscopic mesh-augmented hiatoplasty with simple cardiophrenicopexy (LMAH-C) with laparoscopic mesh-augmented hiatoplasty with fundoplication (LMAH-F) in patients with PEH. ⋯ Laparoscopic repair of PEH should be combined with a fundoplication to avoid postoperative gastroesophageal reflux and resulting esophagitis. Fundoplication-related side effects do not appear to be clinically relevant. Multicenter randomized trials are required to confirm these findings.

Efficacy of a Laparoscopically Delivered Transversus Abdominis Plane Block Technique during Elective Laparoscopic Cholecystectomy: A Prospective, Double-Blind Randomized Trial.
The management of postoperative pain is paramount to facilitate the delivery of day case surgical programs. In recent years, the complexity of procedures carried out has increased to include laparoscopic cholecystectomy. The aim of this study was to evaluate the impact of laparoscopic-assisted 4-quadrant transversus abdominis plane (TAP) block vs periportal local anesthetic wound infiltration in managing postoperative pain. ⋯ This analysis has confirmed the therapeutic benefit of laparoscopically delivered TAP blocks in elective laparoscopic cholecystectomy.

Preoperative vs Postoperative Eradication of Helicobacter pylori in 150 Patients with Gastric Cancer: A Randomized Controlled Trial.
The Maastricht, Asia-Pacific consensus guidelines strongly recommend eradication of Helicobacter pylori in patients who have a history of gastric cancer. This open-label, single-center, randomized controlled trial was conducted to investigate the appropriate timing of eradication for patients undergoing gastrectomy. ⋯ Preoperative H pylori eradication therapy for gastric cancer patients scheduled for gastrectomy is not necessary, regardless of the planned reconstruction procedure.
