Gastric calcinosis ulcer in a renal transplanted patient.

A 53-year-old lady with dysfunctional renal transplant and post-surgical hypoparathyroidism with phosphocalcic metabolism impairment was admitted to hospital because of long-lasting epigastric pain and nausea. An esophagogastroduodenoscopy was performed, visualising a nodular lesion of 1 cm diameter with a depressed and ulcerated base. Microscopically the lesion was in relation with a metastatic calcinosis ulcer.

Endoscopic resolution of intestinal obstruction secondary to colonic gallstone ileus and radicular stenosis of the sigma.

A 93-year-old woman with a history of endometrial adenocarcinoma treated with surgery and pelvic radiotherapy that led to radicular stenosis in the sigma and acute biliary pancreatitis, without subsequent cholecystectomy. She attended the emergency department for abdominal pain, vomiting and abdominal distension, with metallic noises. An abdominal CT scan showed a gallbladder with cholelithiasis, in wide contact with the colonic framework and dilation of the colonic loops with hydro-aerial levels with a partially calcified image embedded in the known sigmoid stenosis, compatible with intestinal obstruction.

Sedation assisted by an endoscopist (SAE) for complex endoscopic procedures. Is it time to change the current guidelines?

Currently, sedation in endoscopic procedures is considered a necessary condition and a criterion of quality in digestive endoscopy. The role of SAE in conventional endoscopic procedures is clearly established in clinical guidelines, but this is not so clear in complex endoscopic procedures, such as ERCP. In recent years, numerous studies have been published, with results similar to those noticed in this article, endorsing the safety, efficacy and efficiency of SAE, when performed by properly trained staff.
