Effect of residual lung expansion on pulmonary function after lobectomy.

Objectives: Pulmonary function after lobectomy is often higher than what is predicted. This occurrence could be related to postoperative expansion of the residual lung. The study aim was to determine if residual lung expansion affects pulmonary function after lobectomy.

Analysis of postoperative weight loss associated with prognosis after sublobar resections for lung cancer.

Objectives: Sublobar resections for lung cancer are increasing worldwide. However, the prognostic significance of weight loss after sublobar resection remains unclear. We aimed to investigate the prognostic significance of weight loss after sublobar resection for lung cancer.

Stereochemical Assignment of the 36-Membered Macrolide Ring Portion of Poecillastrin C.

Absolute configuration at 12 stereocenters in the 36-membered macrocyclic ring portion of poecillastrin C () was disclosed by chemical degradation and NMR analyses of , chemical synthesis, and molecular modeling techniques.

Reduction in drain-related adverse events using the barbed suture method for chest tube wound closure.

Objective: A chest tube is usually placed in patients undergoing general thoracic surgery. Although the barbed suture method has been introduced for chest tube wound closure, its superiority to the conventional suture methods for drain management remains unclear. The study aimed to determine whether the barbed suture method could reduce drain-related adverse events compared to the conventional method.

Strategies and tactics to perform safe pancreaticoduodenectomy for 94-year-old patient: report of a case.

Background: Despite improvement of postoperative management, pancreatoduodenectomy still has a high rate of major complications. Therefore, careful assessment is critically important when we consider high risk surgery for extremely elderly patients.

Case Presentation: A 94-year-old man, who suffered dark urine, epigastric pain, and loss of appetite, was diagnosed as bile duct cancer and underwent endoscopic retrograde biliary drainage.
