BACKGROUND: The use of absorbable sutures in wound closure has been shown to reduce the incidence of surgical site infection (SSI); however, there is no evidence that the intra-abdominal use of absorbable rather than silk sutures reduces the incidence of SSI after gastrointestinal surgery. We report the findings of a phase II trial, designed to evaluate the impact of the intra-abdominal use of absorbable sutures on the incidence of SSI. METHODS: At 19 Japanese hospitals, 1147 patients undergoing elective gastrectomy, colorectal surgery, hepatectomy, or pancreaticoduodenectomy (PD) were randomly assigned to absorbable or silk intra-abdominal suture groups...

PURPOSE: Pharmacologic thromboprophylaxis is recommended for preventing pulmonary embolism according to some abdominal surgery guidelines. However, few reports have so far described pharmacologic thromboprophylaxis after pancreatic surgery. In addition, concern remains regarding postoperative bleeding due to pharmacologic thromboprophylaxis. We investigated the safety and efficacy of enoxaparin, a low-molecular-weight heparin, as postoperative pharmacologic thromboprophylaxis after pancreatic surgery...

PURPOSE: Pancreatic neuroendocrine tumor (PNET) is relatively rare and has a generally better prognosis than does pancreatic cancer. However, as its prognosis in patients with lymph node metastasis (LNM) is unclear, lymph node dissection for PNET is controversial. Our study aimed to clarify the significance of LNM in PNET. METHODS: We retrospectively examined 83 PNET patients who underwent pancreatic resections with lymph node dissection at Kumamoto University Hospital, Saiseikai Kumamoto Hospital, and Kumamoto Regional Medical Center from April 2001 to December 2014...

REVIEW
Haruhiko Nakamura, Toshihide Nishimura
Serum biomarkers provide valuable information about the diagnosis and prognosis of a wide variety of malignant tumors. Despite the identification of several useful serum biomarkers in lung cancer, consensus on their utility has not yet been reached. Furthermore, guidelines and standard protocols to implement their use for patients with lung cancer are lacking, despite the accumulation of much data on the efficacy of several serum biomarkers over recent decades. In this review, we discuss the molecular features, functions, and clinical relevance of the conventional serum biomarkers for lung cancer, including carcinoembryonic antigen (CEA), cytokeratin 19 fragment 21-1 (CYFRA 21-1), tissue polypeptide antigen (TPA), carbohydrate antigen 19-9 (CA19-9), sialyl Lewis(x) (sLe(x)), carbohydrate antigen 125 (CA-125), squamous cell carcinoma-related antigen (SCC-Ag), neuron-specific enolase (NSE), and pro-gastrin-releasing peptide (proGRP), aiming to provide a snapshot of the current landscape and their potential combined utility in the diagnosis and prognosis of lung cancer...

PURPOSE: Many surgeons in Japan use 1-day nasogastric tube (NGT) decompression after gastrectomy as a standard procedure. This prospective randomized study aimed to define whether 1-day NGT decompression is necessary after distal gastrectomy. METHODS: The subjects were 233 patients with gastric cancer, randomized into two groups immediately after distal gastrectomy: one group received 1-day NGT decompression (NGT group, n = 119) and the other did not (no-NGT group, n = 114)...

PURPOSE: Recently, single-incision thoracoscopic surgery (SITS) has been recognized as a favorable treatment choice for primary spontaneous pneumothorax (PSP) compared with conventional three-port video-assisted thoracoscopic surgery (VATS). However, conventional SITS bullectomy often results in collisions with surgical devices. Therefore, we devised a method of SITS using a chest wall pulley for lung excision (PulLE) and modified PulLE (mPulLE) system, which substitutes threads to eliminate such collisions...

BACKGROUND AND PURPOSE: Although the incidence of living donor death is low in Japan, statistics show one living liver donor death in more than 7000 living liver transplants. Thus, medical transplant personnel must recognize that the death of a living organ or tissue transplant donor can occur and develop an appropriate risk management program. METHODS AND RESULTS: We describe how Nagasaki University Hospital established and implemented a Donor Advocacy Team (DAT) program: a risk management program for initiation in the event of serious, persistent, or fatal impairment of an organ, tissue, or cell transplantation from a living donor...

Intrahepatic cholangiocarcinoma (ICC) or combined hepatocellular cholangiocarcinoma (cHCC-CC) is considered to be contraindications for liver transplantation (LT); however, recent studies have shown that the outcomes of LT in small incidental ICC/cHCC-CC tumors are comparable to those in HCC. Studies reporting the survival outcome of patient(s) undergoing LT and found to have incidental or misdiagnosed ICC and/or cHCC-CC in liver explants were reviewed. Our institutional data were also included in the review analysis...
