[Vacuum-therapy for complicated anterior abdominal wall wounds and intestinal fistulas in children].

AIM: To present results of VAC application in children with complicated wounds of anterior abdominal wall combined with intestinal and/or biliary fistulas. MATERIAL AND METHODS: For the last 7 years 8 patients aged from 1.5 months to 15 years with infected postoperative wounds of anterior abdominal wall complicated by intestinal fistulas (6), biliary and intestinal fistulas (1) and biliary fistula (1) have been treated at the surgical department №2 of Russian Children's Clinical Hospital. All patients received complex medical therapy and local VAC-therapy. RESULTS: Granulation and wound's size reduction were observed within first 7 days of VAC-therapy application in 5 (62.5%) children. In 4 (50%) patients at least 1 intestinal fistula has been closed in 15 days after VAC-therapy initiation on the average (range 7--24). Closure of all fistulas and wounds healing were observed in all patients in 28 days (range 16--42) after VAC-therapy initiation on the average. CONCLUSION: VAC-therapy is safe and effective treatment of complicated wounds of anterior abdominal wall combined with intestinal and/or biliary fistulas in children.

[Challenges and opportunities for endoscopic ultrasound in the preoperative diagnosis of topical insulin the pancreas].

Insulinoma in most cases is monohormonal orthoendocrine tumor. This fact limits its searching area by a pancreas. However the insulinoma's clinical picture can be caused by other pathology. Therefore the main task of visual the tumor but also to use all the possibilities of each method for defining type of surgery and avoiding such errors and complications, as pancreatorrhage, damage of bile or pancreatic duct, necrosis of duodenal wall, etc. On the basis of our own experience of endoscopic ultrasound for 61 patients with 66 insulinomas, we have allocated the basic variants of insulinoma ultrasound pictures: hypoechoic, heteroechoic, isoechoic tumor, and also foci without a trustworthy contour. On the basis of the analysis of our own errors we have essentially added the technique, having used multiplane pancreas scanning and biplane tumor scanning. Important points in EUS algorithm are also the following items: detecting tumor relationship to pancreatic surface, distance from the tumor to the ducts, gastrointestinal wall and vessels--for definition of possibility of the tumor enucleation; careful scanning of pancreas even after detecting one tumor--for an exception of multiple tumors, especially at MEN-I; careful scanning of a contour of the gland for an exception of parapancreatic insulinomas; estimation of vascularization not only of the detected tumor and suspicious foci, but also of all the gland--for detection of hypervascularized isoechoic tumors; revealing and the description of focal changes, especially more homoechogeneous in comparison with surrounding parenchyma-- for selection patients for examination by other methods; scanning of zones of possible metastasis. Examination of patients with organic hyperinsulinism demands combined application of two or more techniques. Use of all modern possibilities of endosonography can put this technique on one of the first places in the diagnosis of insulinomas.
