Multicenter Study
Prosthetic graft reconstruction after portal vein resection in pancreaticoduodenectomy: a multicenter analysis.
Use of prosthetic grafts for reconstruction after portal vein (PV) resection during pancreaticoduodenectomy is controversial. We examined outcomes in patients who underwent vein reconstruction using polytetrafluoroethylene (PTFE). ⋯ With careful patient selection, PTFE graft reconstruction of resected PV/SMV during pancreaticoduodenectomy is possible with minimal risk of hepatic necrosis or graft infection. Comparison studies to primary anastomosis and autologous vein reconstruction are necessary.

Randomized Controlled Trial
Online spaced education generates transfer and improves long-term retention of diagnostic skills: a randomized controlled trial.
Retention of learning from surgical training is often limited, especially if the knowledge and skills are used infrequently. Using histopathology diagnostic skills as an experimental system, we compared knowledge transfer and retention between bolus Web-based teaching (WBT) modules and online spaced education, a novel email-based method of online education founded on the spacing effect. ⋯ Online spaced education generates transfer of histopathology diagnostic skills and substantially improves their long-term retention. Additional research is needed to determine how spaced education can optimize learning, transfer, and retention of surgical skills.

In patients with primary hyperaldosteronism, distinguishing between unilateral and bilateral adrenal hypersecretion is critical in assessing treatment options. Adrenal venous sampling (AVS) has been advocated by some to be the gold standard for localization of the responsible lesion, but there remains a lack of consensus for the criteria and the standardization of technique. ⋯ Because 50% of patients would have been inappropriately managed based on CT scan findings, patients with biochemical evidence of primary hyperaldosteronism and considering adrenalectomy should have AVS. The most accurate measurement for AVS lateralization was the post-ACTH stimulation value. Although several factors predict successful AVS lateralization, none are accurate enough to perform AVS selectively.

Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the treatment of choice for patients with ulcerative colitis and familial adenomatous. This study examined the impact of the surgical approach (laparoscopic versus open) to IPAA on short-term outcomes and time to ileostomy closure in 2-stage restorative proctocolectomies. ⋯ Laparoscopic IPAA is safe, with postoperative morbidity comparable with open IPAA. Laparoscopic IPAA can lead to faster recovery and result in faster progression to restoration of intestinal continuity in patients undergoing 2-stage restorative proctocolectomy.

Accurate assessment of cognitive functioning is an important step in understanding how to better evaluate both clinical and cognitive competence in practicing surgeons. As part of the Cognitive Changes and Retirement among Senior Surgeons study, we examined the objective cognitive functioning of senior surgeons in relation to retirement status and age. ⋯ The majority of practicing senior surgeons performed at or near the level of their younger peers on all cognitive tasks, as did almost half of the retired senior surgeons. This suggests that older age does not inevitably preclude cognitive proficiency. The variability in cognitive performance across age groups and retirement status suggests the need for formal measures of objective cognitive functioning to help surgeons detect changes in cognitive performance and aid in their decisions to retire.
