PURPOSE Intraductal tubulopapillary neoplasm is a rare pancreatic tumor. The purpose of this study was to clarify the recurrence type and prognosis in recurrent cases after intraductal tubulopapillary neoplasm resection. METHODS PubMed was searched for previous reports on surgical resection of intraductal tubulopapillary neoplasm of the pancreas that were published from 2009 to July 2020. The clinical features obtained from these reports were summarized and analyzed. RESULTS The clinicopathologi...

In laparoscopic surgery (LS) for colorectal cancer (CRC), the relationship between intraoperative end-tidal carbon dioxide concentration (EtCO2) and surgery-related complications remains unexplored. This study assessed the impact of intraoperative EtCO2 on postoperative complications in LS for CRC. In total, 909 patients who underwent LS for CRC were enrolled. Hypocapnia and hypercapnia were defined as EtCO2 40 mmHg, respectively, and the relationships between hypocapnia or hypercapnia duration ...
To compare the outcomes of laparoscopic radical antegrade modular pancreatosplenectomy (L-RAMPS) with those of open RAMPS (O-RAMPS) in patients with pancreatic ductal adenocarcinoma (PDAC). We reviewed, retrospectively, the medical records of 50 patients who underwent RAMPS for PDAC without resection of major vessels and adjacent organs between 2007 and 2019, and analyzed the relationship between the operative method and surgical and oncological outcomes. Nineteen of the 50 patients underwent L-...
PURPOSE Retroperitoneal teratomas (RPTs) are rare in infants. We report our experience of treating pediatric patients with RPTs over many years at a single institution, with the aim of developing a safe and secure operative strategy for RPTs in infants. METHODS We reviewed the medical records of patients who underwent treatment for RPTs in our institution between April, 1984 and December, 2017, to analyze their background and clinical data. The diagnosis of RPT was confirmed histologically in al...
PURPOSE Pancreaticobiliary maljunction (PBM) without biliary dilatation is a condition in which dilatation of the bile duct is not seen in patients with PBM. Recently, the Japanese Study Group on Pancreaticobiliary Maljunction (JSGPM) published new diagnostic criteria for PBM. In these criteria, biliary dilatation is defined according to the standard diameter at each age. We reviewed cases of pediatric patients with PBM without biliary dilatation. METHODS From 1992 to 2019, 134 patients with PBM...
PURPOSE The systemic immune-inflammation index (SII) is a new marker, defined as the platelet count × neutrophil-to-lymphocyte ratio. This study evaluates the SII as a prognostic marker for the overall survival (OS) of patients who underwent pancreatoduodenectomy (PD) for distal cholangiocarcinoma (DCC). METHODS One hundred and forty patients who underwent PD for DCC between September, 2002 and December, 2015 at our hospital were divided into a low SII (SII < 1450) group and a high SII (SII ≥ 14...

PURPOSES Congenital biliary dilatation (CBD), defined as pancreaticobiliary maljunction (PBM) with biliary dilatation, is a high risk factor for biliary tract cancer (BTC). KRAS and p53 mutations reportedly affect this process, but the mechanisms are unclear, as is the likelihood of BTC later in life in children with CBD. We investigated potential carcinogenetic pathways in children with CBD compared with adults. METHODS The subjects of this study were nine children with CBD and 13 adults with P...

PURPOSE To evaluate the surgical outcomes of lung cancer patients with idiopathic interstitial pneumonia (IIP) and/or coronary artery disease (CAD). METHODS The subjects of this retrospective study were 2830 patients who underwent surgical resection for lung cancer between 2009 and 2018. Seventy-one patients (2.6%) had both IIP and CAD (FC group). The remaining patients were divided into those with IIP only (group F), those with CAD only (group C), and those without IIP or CAD (group N). We comp...
Predicting increased blood loss based on anatomical intervascular relationships is essential in major hepatectomy. We assessed 63 consecutive patients undergoing anatomical hepatectomy exposing the hepatic vein (HV) trunk at two institutes. Correlations between anatomical alterations of the hepatic inferior vena cava (IVC), HV, hepatic IVC, or right atrium (RA) and the blood loss per standard weight (BLSW) or blood transfusion (n = 18) were analyzed. The results of IVC partial clamping (PC) were...

PURPOSE The specific genes or pathways in fibroblasts responsible for the pathogenesis of postoperative abdominal adhesion (PAA) remain to be elucidated. We aim to provide a new insight into disease mechanisms at the transcriptome level. METHODS Male Sprague-Dawley rats were used to establish a PAA model. Primary fibroblasts were separated from normal peritoneal tissue (NF) and postoperative adhesion tissue (PF). RNA sequencing was used to analyze the transcriptome in NF and PF. RESULTS One thou...
