BACKGROUND: Recent trends toward regionalization of complex surgical procedures may increase the risk for care fragmentation during readmissions. Conflicting conclusions have been reported regarding risk factors and consequences of nonindex readmissions (ie, readmission to a separate hospital than the one where surgery was originally performed). We seek to perform a comprehensive review of existing literature. METHODS: Four electronic databases were searched to identify all eligible studies examining the risk factors and outcomes of postoperative nonindex readmission...

BACKGROUND: Appendectomy is the most commonly performed emergency operation in the United States, with approximately 370,000 patients undergoing the procedure every year. Although laparoscopic appendectomy is associated with decreased complications when compared with open appendectomy, the risk for infectious complications, including surgical site infection, intra-abdominal abscess, and sepsis, remains a significant source of postoperative morbidity and health care cost. The goal of this study is to determine whether the appendix retrieval technique during laparoscopic appendectomy affects risk of infectious complications...

BACKGROUND: Several malignancies metastasize to the adrenal gland, especially non-small cell lung cancer, renal cell carcinoma, and melanoma. Adrenalectomy is associated with prolonged survival, but laparoscopic adrenalectomy for this indication is controversial. Our objective was to characterize and quantify outcomes after laparoscopic adrenalectomy for metastases to the adrenal gland. METHODS: A prospectively maintained surgical database and institutional cancer registry were queried for patients who underwent adrenalectomy for metastases...

BACKGROUND: For end-stage hepatic alveolar echinococcosis, insufficient guidance is available regarding surgical treatment, especially for ex vivo liver resection combined with autotransplantation. The indications for this complex surgery require further discussion. METHOD: We reviewed 50 cases of patients who underwent ex vivo liver resection combined with autotransplantation from January 2014 to February 2018. A newly developed classification was used to describe vascular infiltration in all patients, who were divided into four groups based on anatomic lesion features and surgical patterns...

BACKGROUND: The aim of this systematic review is to assess the role of 18-fluorodeoxyglucose positron emission tomography in the preoperative evaluation of intraductal papillary mucinous neoplasms and cystic lesions of the pancreas. METHODS: A computerized PubMed search was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify studies evaluating positron emission tomography in the preoperative evaluation of pancreatic cystic lesions...

BACKGROUND: Patients considered for liver resection with insufficient volume or function of the future remnant liver are candidates for portal vein embolization to allow safe resection. The aim of this study is to analyze the volumetric and functional responses after portal vein embolization and to evaluate predictors of the hypertrophy response. METHODS: All patients who underwent portal vein embolization before liver resection 2006-2017 were included. Patients who did not undergo computed tomography-volumetry and functional assessment with technetium-99m mebrofenin hepatobiliary scintigraphy before and after portal vein embolization were excluded...

BACKGROUND: Pancreatic neuroendocrine neoplasms are a heterogenous group of rare tumors whose natural history remains poorly defined. Accurate prognostication of pancreatic neuroendocrine neoplasms is essential for guiding clinical decisions. This paper aims to summarize all the commonly utilized and recently proposed prognostication systems for pancreatic neuroendocrine neoplasms published in the literature to date. METHODS: A systematic review of Pubmed, Scopus, and Embase databases, of the period from January 1, 2000-November 29, 2016, was conducted to identify all published articles reporting on prognostication systems of pancreatic neuroendocrine neoplasms...

BACKGROUND: Although bone mineral density is reported to be increased in patients with postsurgical hypoparathyroidism (postsurgical HypoPT), the effect of HypoPT on trabecular bone score remains unknown. This study evaluated the long-term effects of HypoPT secondary to total thyroidectomy for differentiated thyroid cancer on trabecular bone score, bone mineral density, and bone turnover markers with a similar group of patients without HypoPT. METHODS: Women with resected differentiated thyroid cancer and either postsurgical HypoPT (n = 25; 8 premenopausal and 17 postmenopausal) or euparathyroid function (n = 98; 14 premenopausal and 84 postmenopausal) were matched for age and body mass index...

BACKGROUND: The impact of the resection margin on survival outcomes in patients with hepatocellular carcinoma remains to be determined. This study aimed to examine the association between the width of resection margin and the presence of microvascular invasion in hepatitis B virus-related hepatocellular carcinoma. METHODS: We reviewed data on 2,508 consecutive patients who underwent liver resection for a solitary, hepatitis B virus-related hepatocellular carcinoma for operative morbidity, tumor recurrence, and overall survival...

BACKGROUND: Utilization of multimodality therapy for clinical stage I-II pancreatic ductal adenocarcinoma is associated with meaningful prolongation of survival. Although the qualitative existence of disparities in treatment utilization by socioeconomic status and race/ethnicity is well documented, the absolute magnitudes of these disparities have not been previously quantified. METHODS: The exposures in this retrospective cohort study of the 2010-2015 National Cancer Database were a 7-value area-level socioeconomic status index and race/ethnicity...

BACKGROUND: Undifferentiated-type early gastric cancers account for a large proportion of gastric cancers in younger patients. Therefore, the clinical outcomes of endoscopic resection in younger patients are a major concern. We aimed to investigate the influence of age on lymph node metastasis and long-term survival after surgery for undifferentiated-type early gastric cancers. METHODS: We identified 4,236 patients who underwent surgery for undifferentiated-type early gastric cancers...

BACKGROUND: An understanding of the overall routine intensive care unit utilization, and characterization of the factors associated with a routine intensive care unit stay, may help identify ways to decrease overutilization of this resource after pancreatic surgery. METHODS: Patients undergoing major pancreatic resection were identified in the Truven Health Analytics (Ann Arbor, MI) MarketScan Commercial Claims and Encounters Database from 2010 to 2014. Routine postoperative intensive care unit admission was defined as an admission to the intensive care unit of 24 hours or less on postoperative day zero...

BACKGROUND: The 30-day readmission rate is increasingly utilized as a metric of quality that impacts reimbursement. To date, there are no nationally representative data on readmission rates after thyroid surgery. We aimed to determine national readmission rates after inpatient thyroidectomy operations and whether select clinical factors were associated with increased odds of postthyroidectomy readmission. METHODS: Using the 2014 Nationwide Readmissions Database, we identified patients undergoing inpatient thyroid surgery as defined by the International Classification of Diseases, Ninth Revision, procedure codes for thyroid lobectomy, partial thyroidectomy, complete thyroidectomy, and substernal thyroidectomy...

BACKGROUND: Temporary portocaval shunt has a positive impact on short-term outcomes after liver transplantation. An alternative to temporary portocaval shunt is a distal passive decompression through mesenterico-saphenous shunt. The purpose of this study was to compare outcomes of these two types of surgical portosystemic shunt and discuss their respective place during the anhepatic phase. METHODS: Patients transplanted with portal decompression during a 4-year period were included...
