[The use of computed tomography in the diagnosis of acute appendicitis]. / Komp'iuternaia tomografiia v dagnostike ostrogo appenditsita (s kommentariem).

AIM: To present the use of computed tomography in the diagnosis of acute appendicitis. MATERIAL AND METHODS: The study was conducted in 139 patients who were hospitalized with suspected acute appendicitis. However, the diagnosis was not clearly confirmed by clinical and ultrasonic data. RESULTS: Computed tomography confirmed/rejected presumptive diagnosis in 90.8% of patients. It was concluded that CT has high diagnostic accuracy to confirm acute appendicitis.

DIAGNOSTIC TRENDS IN ACUTE APPENDICITIS.

The authors presents the results of application of ultrasound investigation, diagnostic laparoscopy and multi-helical computer tomography in diagnostics of acute appendicitis. The research was applied on 139 patients whom clinical diagnosis was hard to establish using clinical - laboratory criteria. Ultrasound signs of acute appendicitis were revealed in 44 patients out of 139 (31,6%). Diagnostic laparoscopy was performed in 37 (26,6%) patients. According to the results of laparoscopy, the diagnosis of acute appendicitis was сonfirmed in 22 (70,2%) cases. The application of CT allowed the authors to confirm or reject the supposed diagnosis in 90,8% patients. The authors came to conclusion that this non-invasive method facilitated to diagnostics of vermiform appendix inflammation and had a high diagnostic accuracy.

[Laser tunneling of the pancreas for treatment of patients with chronic pancreatitis].

Laser tunneling of pancreas for stimulation of neoangiogenesis, regeneration and reverse of sclerotic changes was performed in 17 patients with parenchymatous and fibrosclerotic pancreatitis. The results of clinical trial testify for possibility of safe and effective application of laser tunneling of pancreas in patients with chronic pancreatitis. One of the significant features of the operation was the pain relief and life quality improvement in these patients.

[Laser tunneling of pancreas in chronic pancreatitis].

Obstructive chronic pancreatitis was reproduced in canine model, with the subsequent laser tunneling of pancreas tissue. It was shown, that in the zone of sclerotic changes in pancreas, laser irradiation caused hyperplasia and hypertrophy of acinous cells, augmentation of blood vessels and excretory channels numbers in the reference area, decrease of volume fraction of fibrous tissue that promotes augmentation of pancreas parenchyma.

[Percutaneous laser-induced thermotherapy of nodular goiter]. / Chreskozhnaia lazerindutsirovannaia termoterapiia uzlovogo zoba.

Substantiation of use of laser radiation Nd:YAG (1064 nm) and diode (805 nm) for destruction of thyroid tissue was the purpose of this study based on experimental research of reparative and adaptive processes in thyroid gland. The influence of high-intensity laser radiation was studied in vivo in thyroid gland of 41 dogs. The optimal modes of laser radiation ensured focal destruction of thyroid gland without damage of surrounding organs were selected. The developed modes were used in the treatment of 18 patients with recurrent nodal and multinodal euthyroid goiter. Exposure was performed by puncture method without denudation of thyroid gland. There were no complications during irradiation and nearest postoperative period. In dynamic ultrasonic examination over 2 years the decrease of nodes sizes was revealed in all the patients.
