The impact of immunonutrition on pancreaticoduodenectomy outcomes.

Background: Malnutrition is a significant risk factor for decreased survival in cancer patients undergoing a pancreaticoduodenectomy (PD). Our study aims to investigate the impact of immunonutrition on length of stay (LOS), infection rates, postoperative pancreatic fistula (POPF), and delayed gastric emptying (DGE).

Study Design: This study retrospectively reviewed 344 patients who underwent PD between 2007 and 2018.

Mentorship and formal robotic proficiency skills curriculum improve subsequent generations' learning curve for the robotic distal pancreatectomy.

Background: Minimally invasive distal pancreatectomy is the accepted standard of care. The robotic distal (RDP) learning curve is 20-40 surgeries with operating time (ORT) as the most significant factor. This study evaluates how formal mentorship and a robotic skills curriculum impact the learning curve for subsequent generation surgeons.

Association of Mentorship and a Formal Robotic Proficiency Skills Curriculum With Subsequent Generations' Learning Curve and Safety for Robotic Pancreaticoduodenectomy.

Importance: Learning curves are unavoidable for practicing surgeons when adopting new technologies. However, patient outcomes are worse in the early stages of a learning curve vs after mastery. Therefore, it is critical to find a way to decrease these learning curves without compromising patient safety.

Evolution of a Novel Robotic Training Curriculum in a Complex General Surgical Oncology Fellowship.

Background: Robotic surgery is increasingly being used for complex oncologic operations, although currently there is no standardized curriculum in place for surgical oncologists. We describe the evolution of a proficiency-based robotic training program implemented for surgical oncology fellows, and demonstrate the outcomes of the program.

Methods: A 5-step robotic curriculum began integration in July 2013.

Gastric and Small Bowel Tumors.

The incidence of gastric adenocarcinoma has decreased in the United States over the past 70 years although it continues to have a poor prognosis. While radical resection was initially the primary treatment for adenocarcinoma of the stomach, systemic chemotherapy and radiation have been shown to play a role in prolonging survival in most patient populations. This chapter explores the evidence that guides treatment for gastric cancer today.

Value of intraoperative neck margin analysis during Whipple for pancreatic adenocarcinoma: a multicenter analysis of 1399 patients.

Introduction: During pancreaticoduodenectomy (PD) for ductal adenocarcinoma, a frozen section (FS) neck margin is typically assessed, and if positive, additional pancreas is removed to achieve an R0 margin. We analyzed the association of this practice with improved overall survival (OS).

Methods: Patients who underwent PD for pancreatic ductal adenocarcinoma from January 2000 to August 2012 at 8 academic centers were classified by neck margin status as negative (R0) or microscopically positive (R1) on the basis of FS and permanent section (PS).
