Background/aim: The Barthel index and Katz index are useful in assessing the physical function status of patients. We prospectively evaluated the relationship between the Barthel and Katz indices and postoperative complications in older patients undergoing gastrointestinal surgery., Patients and Methods: We enrolled 250 patients aged ≥65 years who underwent gastrointestinal surgery between September 2018 and April 2020. Postoperative complications within 30 days after surgery were categorized using the Clavien-Dindo classification. The primary endpoint was the incidence of postoperative complications of Clavien-Dindo grade ≥II., Results: Of the 250 patients (age, 74.1±6.2 years), 149 (59.6%) were male and 101 (40.4%) were female. The Barthel index was <100 in 49 patients (19.6%), and the Katz index was B-G in 23 patients (9.2%). Seventy-five patients (30%) developed postoperative complications of Clavien-Dindo grade ≥I, and 72 patients (28.8%) developed complications of Clavien-Dindo grade ≥II within 30 days after surgery. A Barthel index of <100 was more common in the group with complications, while the Katz index did not differ. A Barthel index of <100 was also a significant multivariate predictor of complications of Clavien-Dindo grade ≥II., Conclusion: The Barthel index is a useful predictor of postoperative complications in older individuals undergoing gastrointestinal surgery., (Copyright © 2022, International Institute of Anticancer Research (Dr. George J.

Background/aim: The efficacy and safety of early drain removal following distal pancreatectomy in elderly patients are unclear. We aimed to investigate the short-term surgical outcomes following early drain removal after distal pancreatectomy in elderly patients., Patients and Methods: Fifty-seven patients aged ≥70 years who underwent distal pancreatectomy at our Hospital were enrolled in the study. Data were retrospectively analyzed to evaluate the short-term surgical outcomes following early drain removal after distal pancreatectomy in elderly patients., Results: The incidence of pancreatic fistula following distal pancreatectomy in the early-removal group was significantly lower vs. the conventional group (p=0.022). Multivariate analysis revealed that early drain removal was an independent factor for reducing the risk of pancreatic fistula after distal pancreatectomy in elderly patients (p=0.042)., Conclusion: Early drain removal following distal pancreatectomy is an effective and safe surgical perioperative management procedure to prevent pancreatic fistula in elderly patients., (Copyright© 2020, International Institute of Anticancer Research (Dr. George J.

Background/aim: Indocyanine green (ICG) clearance test is one of the most popular dynamic methods for evaluating preoperative liver function to avoid posthepatectomy liver failure (PHLF). Tc-99m-diethylenetriamine-penta-acetic acid-galactosyl human serum albumin scintigraphy (GSA) also facilitates the direct estimation of functional hepatocytes and can estimate the ICG retention rate (R15); however, in some cases, there is a discrepancy between results of a preoperative examination of ICG-R15 and the estimated ICG-R15 obtained by 99mTc-GSA (GSA-R15). This study evaluated the gap between ICG-R15 and GSA-R15 (ΔICG) for predicting background liver fibrosis in patients who underwent hepatectomy., Patients and Methods: Sixty-four consecutive patients who underwent hepatectomy and preoperative ICG-R15 and GSA-R15 examinations from 2016 to 2019 were retrospectively evaluated. The gap between GSA-R15 and ICG-R15 was defined as ΔICG and the factors predicting liver fibrosis were investigated., Results: In the pathologically-proven cirrhotic group, platelet counts were significantly lower and ΔICG values were significantly larger than those in the non-/early-cirrhotic group. A multivariate analysis identified a higher total bilirubin level, a higher AST level, and a larger ΔICG level as significant predictive factors for liver cirrhosis., Conclusion: Larger ΔICG was found to be an independent preoperative predictor of liver fibrosis and may positively contribute to decision-making before hepatectomy to avoid PHLF., (Copyright© 2020, International Institute of Anticancer Research (Dr. George J.

Background/aim: Recent studies have investigated a novel inflammation-based prognostic system using the combination of platelet count and neutrophil-lymphocyte ratio (COP-NLR). As platelet count decreases with liver damage, we hypothesized that COP-NLR could indicate both inflammation and hepatic reserve in patients with hepatocellular carcinoma (HCC). This study was conducted to clarify the prognostic significance of preoperative COP-NLR in patients with HCC., Patients and Methods: We enrolled 176 patients with histologically-proven HCC who underwent initial curative hepatectomy. Patients were assigned one point each for low platelet count (<15×10 4 /μl) or for high NLR (≥2.0), for hepatic-COP-NLR scores (h-COP-NLR) of 0, 1 or 2., Results: Five-year overall survival (OS) and recurrence-free survival (RFS) rates were 74.5±9%, and 62.2%±9.3% for score 0, 63.6±5.4% and 50.3%±5.6% for score 1, and 45.2±8.8% and 40.6±8.7% for score 2, respectively, and significantly differed (OS: p=0.01; RFS: p=0.03). In multivariate analysis, h-COP-NLR was an independent risk factor for tumor recurrence (HR=1.39, p=0.03) and death (HR=1.71, p=0.02)., Conclusion: h-COP-NLR was an independent predictor for prognosis of HCC patients after hepatic resection., (Copyright© 2019, International Institute of Anticancer Research (Dr. George J.
