Endoscopic Repair of an Iatrogenic Perforation During Gastric Endoscopic Submucosal Dissection
AbstractPerforation is a severe complication of endoscopic submucosal dissection (ESD), and the incidence is reported to be 2–6%. Appropriate endoscopic repair should be administered immediately to prevent severe complications. As a first step, it is very useful to create a neoplasia-free area around the edges of the perforation with a dual knife. Then this area can be safely closed with endoclips. During the procedure, it is strongly advisable to use CO2 insufflation instead of air to reduce abdominal discomfort. Here, this method is demonstrated in a case with a large perforation that occurred during the ESD procedure. This article is part of an expert video encyclopedia
Replica symmetry breaking transition of the weakly anisotropic Heisenberg spin glass in magnetic fields
The spin and the chirality orderings of the three-dimensional Heisenberg spin
glass with the weak random anisotropy are studied under applied magnetic fields
by equilibrium Monte Carlo simulations. A replica symmetry breaking transition
occurs in the chiral sector accompanied by the simultaneous spin-glass order.
The ordering behavior differs significantly from that of the Ising SG, despite
the similarity in the global symmetry. Our observation is consistent with the
spin-chirality decoupling-recoupling scenario of a spin-glass transition.Comment: 4 pages, 4 figure
Management of an Accessory Bile Duct Leak Following Pancreaticoduodenectomy: A Novel Approach Utilizing a Percutaneous and Endoscopic Rendezvous.
Biliary leaks are uncommon but morbid complications of pancreaticoduodenectomies, which have historically been managed with percutaneous drainage, reoperation, or a combination of both. We report a de novo percutaneous-endoscopic hepaticojejunostomy from an anomalous right hepatic duct injured during pancreaticoduodenectomy to the afferent bowel limb. The percutaneous-endoscopic hepaticojejunostomy was stented to allow for tract formation with successful stent removal after 5.5 months. One year after the creation of the percutaneous-endoscopic hepaticojejunostomy, the patient remains clinically well without evidence of biliary leak or obstruction
Fulminant Type 1 Diabetes as a Model of Nature to Explore the Role of C-Peptide
Patients with fulminant type 1 diabetes almost completely lack
C-peptide even soon after the onset of the disease, and the deficiency
continues for the rest of their life. Thus, fulminant type 1 diabetes
could serve as a good model of nature to explore the physiological role
of C-peptide. For example, patients with fulminant type 1 diabetes have
diabetic chronic complications more frequently than those with classical
autoimmune type 1 diabetes 5 years after the onset of diabetes, and the
higher prevalence could be partly attributable to the complete lack of
C-peptide in fulminant type 1 diabetes
