#1
Kanika Kalra, Shipra Arya
Repair of abdominal aortic aneurysms with endovascular techniques has emerged as the first line of therapy, due to procedural ease and excellent patient outcomes. Open aneurysm repair is increasingly used as a secondary option for lesions with anatomic complexity that involve arterial branches. Understanding the impact of endovascular abdominal aortic aneurysms repair on the shift in vascular operation practice for abdominal aortic aneurysms repair, requires a comprehensive and risk-adjusted review of operative outcomes between the 2 repair types...

BACKGROUND: Anemia of critical illness is resistant to exogenous erythropoietin. Packed red blood cells transfusions is the only treatment option, and despite related cost and morbidity, there is a need for alternate strategies. Erythrocyte development can be divided into erythropoietin-dependent and erythropoietin-independent stages. We have shown previously that erythropoietin-dependent development is intact in burn patients and the erythropoietin-independent early commitment stage, which is regulated by β1/β2-adrenergic mechanisms, is compromised...

BACKGROUND: Hemodialysis dependence confers unique physiologic conditions. Prior reports of outcomes after infrainguinal open bypass operations in patients on hemodialysis have been based on relatively small sample institutional series. In this study, we evaluate long-term outcomes after open bypass operations in a large contemporary population-based cohort of hemodialysis patients. We studied all hemodialysis patients who underwent infrainguinal open operation using autogenous versus prosthetic conduits in the United States Renal Data System between January 2007 and December 2011...

BACKGROUND: Improvements in survival after burns have resulted in more patients being discharged home after severe injury. However, the postdischarge health care needs of burn survivors are not well understood. We aimed to determine the rate and causes of unplanned presentation to acute care facilities in the 5 years after major burn injury. METHODS: Data derived from several population-based administrative databases were used to conduct a retrospective cohort study...

BACKGROUND: There is no consensus strategy for treatment of T4 esophageal cancer, and because of this, a better evaluation of treatment response is crucial to establish personalized therapies. This study aimed to establish a useful system for evaluating treatment response in T4 esophageal cancer. METHODS: This study included 130 patients with cT4 esophageal cancer without distant metastasis who underwent (18)F-fluorodeoxyglucose-positron emission tomography before and after a series of induction treatments comprising chemoradiation or chemotherapy...

BACKGROUND: Postoperative hepatic decompensation is a serious complication of liver resection in patients undergoing hepatectomy for hepatocellular carcinoma. Liver fibrosis and clinical significant portal hypertension are well-known risk factors for hepatic decompensation. Liver stiffness measurement is a noninvasive method of evaluating hepatic venous pressure gradient and functional hepatic reserve by estimating hepatic fibrosis. Effectiveness of liver stiffness measurement in predicting persistent postoperative hepatic decompensation has not been investigated...

BACKGROUND: Intestinal ischemia-reperfusion can occur in shock and mesenteric occlusive diseases, causing significant morbidity and mortality. Aside from local injury, intestinal ischemia-reperfusion can result in remote organ damage, particularly in the lungs. Cold-inducible RNA-binding protein (CIRP) was identified as a novel inflammatory mediator. We hypothesized that a deficiency in CIRP would protect the lungs during intestinal ischemia-reperfusion injury. METHODS: Intestinal ischemia was induced in adult male C57BL/6 wild-type and CIRP knock-out (CIRP(-/-)) mice via clamping of the superior mesenteric artery for 60 minutes...

BACKGROUND: Surgeons balance competing interests of minimizing duration of stay with readmissions. Complications that occur early after discharge often result in readmissions. This study examines the relationship between duration of stay, timing of complications, and readmission risk. METHODS: Cases from the 2012-2014 National Surgical Quality Improvement Project-Pediatric were organized into 30 procedural groups. Procedures where duration of stay approximated the median day of complication were identified...

BACKGROUND: In Japan, preoperative chemotherapy is considered essential for resectable stage II or III esophageal cancers. It is important to identify nonresponders for preoperative chemotherapy because continuing ineffective chemotherapy is not beneficial for them. We investigated the correlation between the computed tomography number of tumor and the effect of preoperative chemotherapy in patients with esophageal cancer. METHODS: This retrospective study included 50 patients receiving preoperative chemotherapy with docetaxel, cisplatin, and 5-fluorouracil for stage II or III esophageal cancer...

BACKGROUND: Gastrinomas are rare neuroendocrine tumors that ectopically secrete gastrin and classically originate within the duodenum or pancreas. The presence of primary lymph node gastrinoma is controversial. We report on a single institution's experience with gastrinoma, with focus on primary lymph node tumors. METHODS: Patients who underwent operative resection of gastrinoma between 1992 and 2016 at a single institution were identified. A diagnosis of primary lymph node gastrinoma was defined as tumor confined to one or more resected peripancreatic lymph nodes, negative localization for any extra-nodal disease and normal gastrin postresection...

BACKGROUND: Because operative resection of hepatocellular carcinoma with inferior vena cava tumor thrombus has been associated with a substantial risk of recurrence and postoperative morbidity, adequate patient selection for resection is necessary. Our aim was to propose selection criteria for resection of hepatocellular carcinoma with inferior vena cava tumor thrombus. METHODS: Long-term outcomes were analyzed retrospectively in 39 operative cases of hepatocellular carcinoma with inferior vena cava tumor thrombus (1996-2015)...

BACKGROUND: Although systems of 3-dimensional image-guided surgery are a valuable adjunct across numerous procedures, differences in organ shape between that reflected in the preoperative image data and the intraoperative state can compromise the fidelity of such guidance based on the image. In this work, we assessed in real time a novel, 3-dimensional image-guided operation platform that incorporates soft tissue deformation. METHODS: A series of 125 alignment evaluations were performed across 20 patients...

BACKGROUND: Stage I non-small-cell lung cancer is potentially curable, yet older patients undergo treatment at lower rates than younger patients. This analysis sought to describe the treatment outcomes of nonagenarians with stage I non-small-cell lung cancer to better guide treatment decisions in this population. METHODS: The National Cancer DataBase was queried for patients age ≥90 years old with stage I non-small-cell lung cancer (tumors ≤4 cm). Patients were divided into 3 groups: local therapy, other therapy, or no treatment...

BACKGROUND: Liver disease occurs frequently in short bowel syndrome. Whether small bowel dilation in short bowel syndrome could influence the risk of liver injury through increased bacterial translocation remains unknown. Our aim was to analyze associations between small bowel dilation, mucosal damage, bloodstream infections, and liver injury in short bowel syndrome patients. METHODS: Among short bowel syndrome children (n = 50), maximal small bowel diameter was measured in contrast series and expressed as the ratio to the height of the fifth lumbar vertebra (small bowel diameter ratio), and correlated retrospectively to fecal calprotectin and plasma citrulline-respective markers of mucosal inflammation and mass-bloodstream infections, liver biochemistry, and liver histology...

BACKGROUND: Previous studies have demonstrated a strong association between the preoperative neutrophil-to-lymphocyte ratio and the outcomes of patients with resected hepatocellular carcinoma and colorectal liver metastases. However, the predictive ability of neutrophil-to-lymphocyte ratio in patients with intrahepatic cholangiocarcinoma, especially those treated with preoperative chemotherapy, has been less well described. METHODS: The clinicopathological characteristics, overall survival, and recurrence free survival of all patients with intrahepatic cholangiocarcinoma resected between 2000-2015, were compared between those with elevated (≥3...
