While pneumatosis cystoides intestinalis （PCI） is a rare disease entity associated with a wide variety of gastrointestinal and non-gastrointestinal disorders, PCI associated with massive intra- and retroperitoneal free air is extremely uncommon, and is difficult to diagnose differentially from perforated peritonitis. We present two cases of PCI associated with massive peritoneal free air and/or retroperitoneal air that mimicked perforated peritonitis. These cases highlight the clinical importance of PCI that mimics perforated peritonitis, which requires emergency surgery. Preoperative imaging modalities and diagnostic laparoscopy are useful to make an accurate diagnosis.

Various types of function-preserving gastrectomy and limited gastrectomy have been performed in attempts to improve postoperative quality of life for early gastric *** with preservation of the vagus nerve, which is one of the noteworthy procedures, is performed in Japan to reduce occurrence of cholelithiasis and minimize loss of digestive and absorptive function. Because it is less invasive, the laparoscopic approach is used to treat early gastric *** are few reports in the English literature of laparoscopic

Nickel electroplating has been used practically for decades, is easy to plate, but there is an unknown interest in it. Nickel electroplating as a basis of surface treatment is shown practically from basics to the applied electronics use. At first the basics of nickel electroplating, for example, purpose, use, merit & demerit, nickel plating solution, current efficiency, limiting current density, additional agents and their behaviors are surveyed. And the points of nickel deposition already practically used such as decorative nickel plating, satin nickel plating and functional nickel plating, which has very high throwing power and has been used for electronics, are described in detail.

AIM To determine the prognostic factors associated with mortality in patients with gastric fundal variceal (GFV) *** In total, 42 patients were endoscopically diagnosed with GFV bleeding from January 2000 to March 2014. We retrospectively reviewed the patients' medical records and assessed their history, etiology of liver cirrhosis, disease conditions, treatment options for GFV bleeding, medications administered before and after onset of GFV bleeding, blood test results(hemoglobin, albumin, and bilirubin concentrations), and imaging results(including computed tomography and abdominal ultrasonography). We also assessed the prognostic factors associated with short-term mortality(up to 90 d) and long-term mortality in all *** Multivariate analysis showed that prophylactic administration of antibiotics was an independent prognostic factor associated with decreases in short-term mortality (OR = 0.08, 95%CI: 0.01-0.52) and longterm mortality (OR = 0.27, 95%CI: 0.08-0.91) in patients with GFV bleeding. In contrast, concurrent hepatocellular carcinoma (HCC) and regular use of proton pump inhibitors (PPI) were independent prognostic factors associated with increases in shortterm mortality(HCC: OR = 15.4, 95%CI: 2.08-114.75; PPI: OR = 12.76, 95%CI: 2.13-76.52) and long-term mortality (HCC: OR = 7.89, 95%CI: 1.98-31.58; PPI: OR = 10.91, 95%CI: 2.86-41.65) in patients with GFV bleeding. The long-term overall survival rate was significantly lower in patients who regularly used PPI than in those who did not use PPI(P = 0.0074).CONCLUSION Administration of antibiotics is associated with decreased short- and long-term mortality, while concurrent HCC and regular PPI administration are associated with increased short- and long-term mortality.

Endoscopic submucosal dissection(ESD)is a globally accepted minimally invasive therapy for early-stage gastrointestinal tract *** numerous electrosurgical knives have been developed for ESD,technical difficulties and high complication rates(bleeding and perforation)have limited their use *** grasping-type scissors forceps[clutch cutter(CC)]is the first forceps-type resection device developed with reference to hemostatic *** aim was to allow easy and safe ESD throughout the gastro-intestinal tract,as a biopsy technique,using one *** CC can grasp the target tissue accurately and pull it away from the underlying muscle layer prior to energizing the tissue,for safe and effective incision and hemostasis during *** clinical studies showed that ESD using the CC(ESD-CC)is a safe(perforation rate:0%-3.6%;delayed bleeding rate:0%-4.2%),technically efficient(en-bloc resection rate:88.9%-100%),and single-device method for dissecting early-stage gastrointestinal tract *** ESD-CC technique is simple and easy to learn because it can be completed simply by repeating the grasp,pull,and coagulate and/or incise actions using an electrosurgical *** reported self-completion rate by nonexperts was significantly better with the CC than with conventional knives(61.7%vs 24.5%,respectively;P<0.001).Furthermore,the CC is used for other endoscopic therapies,such as endoscopic polypectomy for large pedunculated polyps,endoscopic myotomy for Zenker’s diverticulum,endoscopic treatment of buried bumper syndrome,and endoscopic necrosectomy for wall-off pancreatic *** initial reports using CC for these therapies have shown favorable *** this review,we describe the structural features of the CC,how to use the instrument,efficacies of ESD-CC,and other unique endoscopic therapies using the CC.
