Introduction: Nearly half of the adult population in the United States has been diagnosed with hypertension. Adrenal hormonal hypersecretion is a leading cause of secondary hypertension. Adrenal vein sampling (AVS) may assist in differentiating between unilateral and bilateral adrenal hormonal hypersecretion to identify patients who are candidates for adrenalectomy. We reviewed the use of AVS at our institution along with associated outcomes after adrenalectomy. Materials and Methods: A retrospective chart review was conducted of patients with a diagnosis of primary hyperaldosteronism (PA) or adrenocorticotropic hormone-independent Cushing syndrome (AICS) and who underwent adrenalectomy between January 1, 2010, and December 1, 2021. Patient data of baseline characteristics, preoperative workup, including AVS, and postoperative outcomes were collected and analyzed. Results: Seventy-one patients were identified in the study period (48 PA and 23 AICS). Computed tomography scan identified unilateral adrenal nodules in 52 patients (29 left; and 23 right), bilateral nodules in 13 patients, and no nodules in 6 patients. AVS was performed in 45 patients with PA (93%) and 5 patients with AICS (21%). After surgery, the number of PA patients with hypokalemia or requiring potassium supplementation significantly decreased after adrenalectomy (before surgery: 33 [68.7%]; and after surgery: 5 [10.4%], P < .01). The number of medications required for hypertension in AICS patients also significantly decreased. No major adverse events were noted. Conclusions : Our long-term experience demonstrates the ongoing use of AVS during workup of patients with primary hyperaldosteronism and for select patients with adrenocorticotropic hormone-independent Cushing syndrome. However, a low level of discordance between imaging and AVS findings in PA patients suggests that there may be a subset of patients in whom preoperative AVS is not necessary.

The NCCN Guidelines for Pancreatic Adenocarcinoma discuss the diagnosis and management of adenocarcinomas of the exocrine pancreas and are intended to assist with clinical decision-making. These NCCN Guidelines Insights discuss important updates to the 2019 version of the guidelines, focusing on postoperative adjuvant treatment of patients with pancreatic cancers.

Objective: The European Guidelines Meeting on Laparoscopic Liver Surgery was held in Southampton on February 10 and 11, 2017 with the aim of presenting and validating clinical practice guidelines for laparoscopic liver surgery. Background: The exponential growth of laparoscopic liver surgery in recent years mandates the development of clinical practice guidelines to direct the speciality's continued safe progression and dissemination. Methods: A unique approach to the development of clinical guidelines was adopted. Three well-validated methods were integrated: the Scottish Intercollegiate Guidelines Network methodology for the assessment of evidence and development of guideline statements; the Delphi method of establishing expert consensus, and the AGREE II-GRS Instrument for the assessment of the methodological quality and external validation of the final statements. Results: Along with the committee chairman, 22 European experts; 7 junior experts and an independent validation committee of 11 international surgeons produced 67 guideline statements for the safe progression and dissemination of laparoscopic liver surgery. Each of the statements reached at least a 95% consensus among the experts and were endorsed by the independent validation committee. Conclusion: The European Guidelines Meeting for Laparoscopic Liver Surgery has produced a set of clinical practice guidelines that have been independently validated for the safe development and progression of laparoscopic liver surgery. The Southampton Guidelines have amalgamated the available evidence and a wealth of experts’ knowledge taking in consideration the relevant stakeholders’ opinions and complying with the international methodology standards.

AbstractAfter decades on the margins of primary health care, surgical and anaesthesia care is gaining increasing priority within the global development arena. The 2015 publications of the Disease Control Priorities third edition on Essential Surgery and the Lancet Commission on Global Surgery created a compelling evidenced‐based argument for the fundamental role of surgery and anaesthesia within cost‐effective health systems strengthening global strategy. The launch of the Global Alliance for Surgical, Obstetric, Trauma, and Anaesthesia Care in 2015 has further coordinated efforts to build priority for surgical care and anaesthesia. These combined efforts culminated in the approval of a World Health Assembly resolution recognizing the role of surgical care and anaesthesia as part of universal health coverage. Momentum gained from these milestones highlights the need to identify consensus goals, targets and indicators to guide policy implementation and track progress at the national level. Through an open consultative process that incorporated input from stakeholders from around the globe, a global target calling for safe surgical and anaesthesia care for 80% of the world by 2030 was proposed. In order to achieve this target, we also propose 15 consensus indicators that build on existing surgical systems metrics and expand the ability to prioritize surgical systems strengthening around the world.
