Visceral Fat Associated with Worsening of Recurrent Esophageal Varices in Alcoholic/Nonalcoholic Steatohepatitis-Related Liver Cirrhosis.

Background: Alcoholic steatohepatitis and nonalcoholic steatohepatitis-related liver cirrhosis (ASH/NASH-LC) are major causes of esophageal varices (EVs). However, the association between high visceral fat and exacerbation of EVs remains unclear. The aim of this study was to clarify the association of visceral fat and recurrence rate of EVs in ASH/NASH-LC and to identify independent predictors associated with recurrence.

[A Case of Resected Diffuse Large B-Cell Lymphoma Diagnosed with Liver Metastasis and Peritoneal Dissemination after Surgery for Sigmoid Colon Cancer].

We experienced a case of diffuse large B-cell lymphoma(DLBCL)that developed around the kidney about 1 year after surgery for sigmoid colon cancer. In this case, imaging findings suggestive of liver metastasis were also observed at the same time of diagnosis, therefore, diagnosis was difficult because the possibility of peritoneal dissemination could not be ruled out. The lesion was excised by surgery and a definitive diagnosis was obtained by tissue diagnosis, leading to appropriate treatment.

Predictive Postoperative Inflammatory Response Indicators of Infectious Complications Following Gastrectomy for Gastric Cancer.

Background: Perioperative factors are useful for predicting postoperative infectious complications (PIC) in gastric cancer. Specifically, postoperative inflammatory response indicators (PIRI), [C-reactive protein (CRP) level, body temperature (BT), and white blood cell (WBC) count], are widely used in clinical practice. We investigated predictive factors for PIC, including PIRI, to establish a simple and practical indicator of postoperative complications after gastrectomy.

The efficacy of endoscopic submucosal dissection compared with modified endoscopic aspiration mucosectomy by assessing the short-term therapeutic results for differentiated mucosal gastric cancer.

Background: We developed a modified method of endoscopic aspiration mucosectomy (m-EAM) which includes the pre-cutting of the peripheral mucosa before aspiration, and which has been employed in this department since 1998. An endoscopic submucosal dissection (ESD), which enables the resection of a larger area of the lesion using newly-developed surgical devices, has also been employed here since March 2003. This study was performed to investigate the efficacy of ESD at the present time by assessing the short-term therapeutic results for the procedure in patients with a preoperative diagnosis of early-stage differentiated gastric mucosal cancer, by tumor diameter, as well as by comparing these results with those obtained previously with m-EAM.

Changes of nutritional status after distal gastrectomy in patients with gastric cancer.

Background/aims: In Japan, distal gastrectomy is the most common operation performed to treat gastric cancer. However, this procedure often leads to postoperative problems such as weight loss.

Methodology: We assessed the changes of nutritional status early after operation and the associations of the postoperative body weight (as a percentage of the preoperative weight) and background factors in patients who underwent distal gastrectomy.

[A short-term outcome of endoscopic submucosal dissection (ESD) for early gastric cancer].

In this study, we investigated a short-term outcome of 56 cases of ESD for early gastric cancer performed in our department concerning the tumor diameter within or over 20 mm.
