[The clinical value of miniature ultrasonic probes on diagnosis and treatment of digestive tract diseases].

OBJECTIVE: To investigate the clinical value of miniature ultrasonic probes (MUP) in the diagnosis and treatment of digestive tract diseases. METHODS: 537 patients who were indicated for endoscopic ultrasorography (EUS) underwent EUS with 7.5 - 20 MHz MUP and double-cavity electronic endoscope. According to the diagnoses of MUP, those patients who presented the indication of treatment were treated by endoscopic resection or surgical excision respectively, the postoperative histological results were compared with the preoperative diagnoses of MUP. A follow-up with MUP was periodically made for a few patients without endoscopic resection or surgical excision. RESULTS: Among the 537 patients the diagnosis of gastrointestinal submucosal lesions was made in the 256 cases, polyp in 56 cases, inflammatory prominence in 37 cases, extrinsic compression 53 cases, digestive tract cancer 50 cases, peptic ulcer 17 cases, cholecystolithiasis 11 cases, chronic pancreatitis in 8 cases, and achalasia 2 cases and 47 cases were diagnosed as normal, After examination of MUP, 220 patients were treated by endoscopic resection or surgical excision respectively, the postoperative histological results of 211 patients were completely consistent with the preoperative diagnosis of MUP, and diagnostic accuracy of MUP was 95.9%. The result of follow-up with MUP indicated that gastrointestinal leiomyoma, lipoma, phlebangioma and cyst were unchanged within 1 - 2 years. The patients who were treated by endoscopic resection or centesis showed no complication. CONCLUSION: EUS with MUP is a valuable method in diagnosis of gastrointestinal submucosal lesions, staging of digestive tract cancer and diagnosis of biliary-pancreatic diseases. It plays a very important role for making scientific, effective, safe and economic therapeutic plan.

[Contemporary low-invasive, videoendoscopic and organ-sparing abdominal operations].

The paper presents the results of low-invasive, videosurgical, and organ-sparing operations, developed and performed by the authors. Original low-invasive techniques of external, external-and-internal and internal bile-duct drainage, and bile-duct endoprosthesis replacement have been performed in 25 patients with benign and malignant bile-duct strictures. Transcutaneous puncture drainage operations, including those combined with an original method of transdrainage sclerotherapy with nitric oxide, have been performed in 93 patients with postnecrotic pancreatic cysts. Endoscopic virsungotomy have been performed as part of the complex treatment of 43 patients with external pancreatic fistulas and 14 patients with polycystic head of pancreas. X-ray endovascular embolization has been performed in 7 patients with internal arterio-pancreatic fistulas. Program laparoscopic abdominal cavity sanation by an original method have been performed in 50 patients with diffuse peritonitis. The results of the study demonstrate high effectiveness of the methods, which in most cases can be applied as an alternative to conventional surgical interventions.

The possible diagnostic role of endoscopic ultrasound in patients with dyspepsia.

BACKGROUND: Dyspepsia is common in clinical practice with frequent relapses and often requires multiple investigations to assess intraluminal and extraluminal etiologies. Endoscopic ultrasound (EUS) has the potential of serving both purposes in a single setting. MATERIAL AND METHOD: Patients with dyspepsia who underwent EUS in four-year period were retrospectively reviewed. Diagnostic findings of US, final diagnoses were noted and compared with the reference standards. RESULTS: 131 patients with a mean age +/- SD of 50 +/- 12.7 years were included. The common diagnoses were non-ulcer dyspepsia in 56%, symptomatic gallstone (GS) in 22.9%. EUS detected two GS missed by transabdominal ultrasound (TUS). EUS missed one GS documented by surgery. EUS detected seven cases of ERCP-proven CBD stones undetected by TUS and had a sensitivity, specificity, positive predictive value and negative predictive value for CBD stones of 87.5%, 91.7%, 87.5%, and 91.7% respectively. CONCLUSION: EUS is a potential investigation for the management of dyspepsia.
