Background: The Naples prognostic score (NPS) is an effective and objective tool to assess the immunenutritional status of patients with malignant tumors. The aim of this study was to investigate the clinical significance of preoperative NPS on short-and long-term outcomes after pancreatoduodenectomy (PD) for ampullary carcinoma.Methods: We retrospectively analyzed 404 consecutive patients with ampullary carcinoma who underwent PD between January 2012 and June 2018. Preoperative NPS was calculated from serum albumin and total cholesterol concentrations, and the neutrophil-lymphocyte ratio and lymphocyte-monocyte ratio (LMR). Patients were then divided into three groups according to their NPS. Clinicopathological variables, postoperative outcomes, and survival data were compared between the three groups. Univariate and multivariate Cox analysis of overall survival (OS) and recurrence-free survival (RFS) were also conducted, and time-dependent receiver operating characteristic (ROC) curves were created to evaluate the discriminatory ability of the prognostic scoring systems.
Pancreatic surgery is one of the most complex and challenging fields in abdominal surgery associated with extensive surgical trauma, damage to adjacent organs, a long operation time and a high incidence of postoperative complications. Since the early 1990s, laparoscopic techniques have been applied to a growing number of pancreas surgeries, and great progress has been achieved in laparoscopic pancreaticoduodenectomy. As surgeons become proficient in laparoscopic pancreaticoduodenectomy techniques, laparoscopic techniques are gradually used in other pancreatic surgeries, such as laparoscopic distal pancreatectomies and laparoscopic duodenum-preserving pancreatic head resection (LDPPHR), which may benefit patients by reducing postoperative pain and hospital stays and providing a quick recovery to normal activity. Recently, a great number of literature have introduced LDPPHR. It is a good surgical method for benign and low-grade malignant tumors of the pancreatic head. Although LDPPHR is technically feasible, it is not yet generally practicable and limited to highly skilled endoscopic surgeons, and the long-term results after LDPPHR are still not well defined. This article aims to provide a literature review of LDPPHR to assess its feasibility, safety, postoperative recovery, and future outlook according to early experiences of this technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
