Elevated Risk of Complications in Patients Receiving Dual Antithrombotic Therapy Undergoing Hepatectomy: A Single‐Center Audit of 749 Cases

Annals of Gastroenterological Surgery, EarlyView.
This single‐center retrospective study evaluated perioperative outcomes after hepatectomy in 749 patients, including 140 receiving ATT, using propensity score matching to compare ATT and non‐ATT cohorts. Under standardized perioperative management, ATT did not increase major bleeding, transfusion, or severe morbidity overall; however, within the ATT ...

Psoas Muscle Volume as a Predictor of Postoperative Complications in Patients Undergoing Emergency Surgery for Strangulated Small Bowel Obstruction: A Retrospective Single‐Center Study

Annals of Gastroenterological Surgery, EarlyView.
This retrospective study identified low preoperative psoas muscle volume, measured by computed tomography, as an independent predictor of postoperative complications in patients undergoing emergency surgery for strangulated small bowel obstruction. Low psoas muscle volume, particularly in older adults, was associated with cardiopulmonary and systemic ...

Impact of Prophylactic Cefepime on Surgical Site Infection and Severe Morbidity in Patients Who Underwent Pancreaticoduodenectomy With Preoperative Biliary Drainage

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Although prophylactic broad‐spectrum antibiotics can reduce postoperative complications after pancreaticoduodenectomy (PD), the optimal regimen remains uncertain. This study evaluated the impact of prophylactic cefepime (CFPM) on surgical site infection (SSI) and severe morbidity after PD with preoperative biliary drainage.

Surgical Outcomes and Recurrence Management in Borderline Resectable Hepatocellular Carcinoma: Implications for Multidisciplinary Strategies

Annals of Gastroenterological Surgery, EarlyView.
Multivariate analysis identified that up‐to‐7 out (p < 0.001), lymph node metastasis (p < 0.001), and non‐anatomical resection (p = 0.02) were independent predictors of cancer recurrence, while older age (p = 0.01), Child‐Pugh B (p < 0.001), up‐to‐7 out (p = 0.01), macrovascular invasion (p = 0.01), and lymph node metastasis (p < 0.001) were ...

Asymptotic Distributions of Multivariate Intermediate Order Statistics

Theory of Probability & Its Applications, 1997
Summary: Let \(\{X_n= (X_n^{(1)}, \dots, X_n^{(d)})\), \(n\geq 1\}\) be independent, identically distributed random vectors with a common nondegenerate distribution function and for each \(n \geq 1\) and each \(k=1, \dots, d\), denote \(X_{1;n}^{(k)} \leq\cdots \leq X_{n;n}^{(k)}\) as the order statistics of \(X_1^{(k)}, \dots, X_n^{(k)}\).

EXACT DISTRIBUTION OF CERTAIN GENERAL TEST STATISTICS IN MULTIVARIATE ANALYSIS

Australian Journal of Statistics, 1986
SummaryIn this paper, exact solution of Wilks' type‐B integral equation has been obtained in its most general form as a series of weighted gamma distributions. This general result then gives the distributions of many test statistics in multivariate analysis. In particular the distributions of Wilks' Λ, the sphericity test criterion, and Bartlett's test

Distributions of a Class of Statistics Useful in Multivariate Analysis

Journal of the American Statistical Association, 1983
Abstract In this article, exact and asymptotic distributions of a class of statistics whose moments are of a particular form have been obtained. An application to Wilks's criterion for testing a linear hypothesis is given, and it is shown by numerical comparison that the first term of the asymptotic expansion of the distribution obtained in this ...
