Cryptogenic mycotic aneurysm of the superior mesenteric artery.

Visceral artery aneurysms as a result of arterial degenerative disease are rare (0.1-2%), and superior mesenteric artery (SMA) accounts for 3.2% of all reported series. However, mycotic SMA aneurysms (SMAAs) are even rarer, and to the best of our knowledge, this is the first report of cryptogenic mycotic aneurysm of SMA by Enterococcus faecalis (EF). We report a case of 77-year-old man with 6-week history of supra pubic/left iliac fossa pain, weight loss and fever. The computed tomography demonstrated an incidental finding of 4.4 × 3-cm SMAA with no primary foci. The subsequent serology and specimen confirmed EF. Aneurysmectomy without bypass grafting along with antimicrobial therapy resulted in full recovery of the patient.

PEG fixation of an upside-down stomach using a flexible endoscope: case report and review of the literature.

INTRODUCTION: Upside-down stomach usually is asymptomatic in adults, but sometimes it can cause regurgitation, vomiting, and weight loss. This condition has an incidence increasing with age thus increasing the risk of surgical intervention. CASE REPORT: A 90-year-old man was admitted with dysphagia, postprandial regurgitation, and an 18 kg weight loss in the past year. Gastroscopy revealed a significantly dilated, cranky esophagus and an upside-down stomach. The diagnosis was confirmed by a barium swallow and computed tomography. The stomach was repositioned with a gastroscope using insufflation and an α-loop maneuver under fluoroscopic guidance. A percutaneous endoscopic gastrostomy tube was then inserted to fix the stomach. The patient was discharged on the first postinterventional day. He gained 6 kg in the next 2 months. DISCUSSION: High-risk patients with upside-down stomach can be managed by endoscopic repositioning of the stomach and percutaneous endoscopic gastrostomy fixation. This is a useful alternative therapeutic intervention. There have been 14 similar cases being reported in the literature.

[Gastro-entero anastomosis with flexible endoscope with the help of rare-earth magnets on biosynthetic model made of the gastrointestinal tract of slaughtered pigs]. / Flexibilis endoscoppal készített gastroentero anastomosis ritkafödfém mágnesek segítségével sertés gyomorbel traktus felhasználásával készített bioszintetikus modellen.

UNLABELLED: Gastro-entero anastomosis with flexible endoscope with the help of rare-earth magnets on biosynthetic model made of the gastrointestinal tract of slaughtered pigs BACKGROUND: Numerous malignant diseases may cause gastric outlet obstruction. The surgical gastrointestinal bypass, besides the fact that it requires narcosis, is also associated with high risks for patients with poor general condition. Endoscopic insertion of self-expandable metal stent is less invasive, but often causes complications. In the last years some studies examined a new minimal invasive technique, in which magnets are used to create gastroenteric anastomosis. MATERIAL AND METHOD: A biosynthetic model was developed from combined synthetic materials with biogenic specimens taken from slaughtered domestic pigs. The procedure was performed with endoscopic and fluoroscopic guidance. To increase X-ray contrast differences the model was put into physiological saline solution. Two rare-earth magnets (Br: 2500 Gauss, D: 10 mm) with central hole were inserted with the help of a guiding wire and duodenal probe. The first magnet was placed in the first jejunal loop; the second one was placed in the stomach. The gastric magnet was maneuvered using the endoscope. When the magnets reached the right position, the guiding wires were removed to let the magnets stick together. The pressure between the magnets will result in a sterile inflammation on the living tissue which develops adhesion between the bowels, and 7-10 days later anastomosis will develop as a result of the necrosis. RESULT: The biosynthetic model could be used for training endoscopy without sacrificing animals. In the end of the procedure the magnets stuck together across gastric and jejunal walls in all ten cases successfully. By practice the period necessary for the procedure could be decreased from 40 to 20 minutes. CONCLUSION: The technique could be made with standard upper endoscope and instruments, and after practice on living animals it could potentially be a useful solution for complaints of gastric outlet obstruction.

[Transgastric gastro-jejunal anastomosis with flexible endoscope on a biosynthetic model]. / Transgastricus gastrojejunalis anastomosis készítése flexibilis endoszkóppal bioszintetikus modellen.

INTRODUCTION: In the last few years the rapid development of flexible endoscopies has opened new possibilities in minimal invasive procedures. With the help of these techniques the exposure, the risk of complications and the healing period of the patient might be reduced. One of these procedures is the transgastric intervention. Through an incision on the wall of the stomach, the endoscope could be led into the abdominal cavity, where several interventions can be performed. The aim of the study was to examine the technical feasibility and the success of the formation of gastro-jejunal anastomosis. Meanwhile the difficulties of the method could be explored in order to introduce this method in human use. METHOD: A lifelike biosynthetic model was made from a slaughtered domestic pig's gastrointestinal tract (stomach and the first few jejunum loops) which was fixed onto a plastic frame. Two single-channel gastroscopes were inserted into the stomach. On the wall of the stomach an approximately 2 centimetres wide incision was made by the electrocoagulator with a needle-knife. Through it the first jejunum loop was grasped by a foreign-body forceps and then was retracted into the stomach. Subsequently the jejunum loop was held safely with the first endoscope. Parallel to it an incision was made on the jejunum by the electrocoagulator. The authors managed to securely unite the open edges of the gastric wall and the jejunum with endoclips. RESULT: The model was good for practising. The anastomosis is technically feasible and was successfully made on biosynthetic porcine model using the transgastric route. Although the incisions both on the gastric wall and on the jejunum loop were made easily, the fixing of the anastomosis might be questionable. CONCLUSION: It was revealed that more experiments and the development of new, special instruments are needed in order to conduct the anastomosis safely.
