[Surgical treatment of ACTH-ectopic syndrome]. / Khirurgicheskoe lechenie AKTG-éktopicheskogo sindroma.

ACTH-ectopic syndrome is a severe, multiple-symptom disease characterized by secretion of adrenocorticotropic hormone (ACTH) by ectopic tumor, increased release of adrenal cortical hormones and clinical picture of hypercorticism. Diagnosis and treatment of ACTH-ectopic syndrome is still difficult problem despite the achievements of modern medicine. There are several unresolved issues including optimal diagnostic algorithm, indications for various surgical procedures and their optimal dates. This review is devoted to these questions.

[Massive abdominal hydatidosis]. / Total'noe porazhenie briushnoi polosti ékhinokokkozom.

Clinical symptoms and localization of echinococcosis are various. Clinical observation of successful surgical treatment of secondary multiple abdominal lesion with echinococcosis is presented in the article. Certain features of diagnosis and surgical treatment are described.

[Echinococcosis and pregnancy: approaches to the treatment]. / Ékhinokokkoz i beremennost': podkhody k taktike lecheniia.

AIM: To develop treatment strategy in pregnant women with liver echinococcosis. MATERIAL AND METHODS: There were 21 women with confirmed diagnosis of liver echinococcosis who were divided into 2 groups. Group I consisted of 17 patients with cysts Charbi grade I-III. They underwent percutaneous puncture and antiparasitic management of the cyst under intravenous sedation. Group II included 4 patients with cysts grade IV-V and those with multiple cysts. They underwent conventional surgery. RESULTS: In one patient, fetal death occurred in 20 hours after surgery and it was not associated with the procedure. There were no complications in other patients. Uneventful childbirth was noted in all of them. CONCLUSION: Percutaneous puncture in the second trimester of pregnancy is effective and safe procedure for prevention of complications of echinococcosis in late pregnancy and childbirth. Conventional surgery is alternative if percutaneous intervention is not advisable.

Combined treatment of nonresectable cholangiocarcinoma complicated by obstructive jaundice.

BACKGROUND: The five-year survival rate for successful surgical treatment of cholangiocellular cancer is only 20-40%, and in the case of an unresectable tumor, the life expectancy does not usually exceed 6 months. Survival decreases with the presence of jaundice, due to the spread of the tumor process along the bile ducts, leading to their obstruction. We report outcomes of patients with nonresectable bile duct carcinoma complicated by obstructive jaundice treated with Photodynamic Therapy (PDT). METHODS: Combined diagnosis and treatment included percutaneous cholangiostomy, intraductal video fluorescence diagnostics, photodynamic therapy, and bile duct stenting. All patients were treated at the Sechenov University Oncology Center in Moscow. The results of treatment of 33 patients have been presented. The intraductal diagnosis of malignant bile duct lesions was performed after cholangiostomy using the endovideofluorescence module for minimally invasive surgery and endoscopy. With the use of this method, it is the first time in Russia that it has become possible to obtain a videofluorescent image of the tumor and to determine the high level of photosensitizer accumulation in all cholangiocarcinoma patients. The preparations Photolon, Radachlorin, and Photosens were employed as photosensitizers (PS). Intraductal photodynamic therapy was used to achieve the antitumor effect. Laser power density was about 200 mW/cm2. RESULTS: We present initial results, improved the diagnostic possibilities in this difficult localization of carcinoma, and demonstrated the feasibility of prolongation of life without significant deterioration of its quality. The average survival time in the treatment group is 9.5 months. CONCLUSION: The treatment of patients with nonresectable cholangiocarcinoma with Photodynamic Therapy should be an available option. In this context, the additional use of intraductal endovideofluorescence diagnostics is a highly specific technique that allows reliable detection of the photosensitizer accumulation predominantly by the tumor tissue and appears promising. As shown by our experience, flourescent localization followed by Photodynamic Therapy, enabled us to improve diagnostic techniques and treat the tumor with improved outcome.

[The use of Octreotide-depo for the pancreatitis' prophylaxis after radical surgery of gastric cancer with lymphadenectomy].

The efficacy of the medicamentous prophylaxis of the acute postoperative pancreatitis (APP) was estimated in 594 patients. They all were divided into 3 groups: 1st was treated with octreotide, 2nd - with octreotide-depo, 3rd - with 5-ftoruracil and dalargin. Patients of the 3rd group showed the highest levels of α-amylase in both blood and drainage fluid during the early postoperative period. The frequency and severity of postoperative complication rates were the lowest in those patients, who received octreotide-depo and was 3,06%; whereas among patients of the 2nd group it was 16,8% and among those, who were treated with 5-ftoruracil and dalargin, it was 22,4%. The destructive forms of pancreatitis were registered in 2nd and 3rd groups in 1 and 3 patients, respectively. Intraabdominal abscesses were registered in 1 patient of the 1st and 6 patients of the 3rd group, respectively. The lethality rate was 0.9% in the 1st group; 1.02% in the 2nd and 1.8% in the 3rd group. The use of somatostatine analogues in the prophylaxis of postoperative complications proved to decrease overall complications' rate and, first of all, the rate of postoperative destructive pancreatitis. The use of the prolonged forms of somatostatine analogues, i.e., octreotide depo 10 mg is considered to be highly effective.

[Capacities of diagnostic volumetric multislice spiral computed tomography in the diagnosis of gastric cancer].

In the period 2009 to 2010, diagnostic multislice spiral computed tomography (MSCT) was carried out in 49 patients with gastric cancer. The efficiency of dynamic MSCT in detecting a tumor and determining its locoregional extent was evaluated. The results of dynamic MSCT were compared with those of postoperative histological examination. The possibility of detecting gastric cancer by dynamic MSCT was ascertained to depend on the depth of tumor invasion and to average 29, 71, 72, and 77% for T1, T2, T3, and T4, respectively. Dynamic MSCT showed a correlation between the frequency of metastatic lesion and the sizes of lymph nodes (r = 0.54; p = 0.0001) and their number (r = 0.82; p < 0.0001).

[The functional results of distal subtotal gastric resections in cancer patients]. / Funktsional'nye rezul'taty distal'nykh subtotal'nykh rezektsii zheludka u bol'nykh rakom.

It was clinically proven that a gastrojejunostomy with Rue-type anastomosis, following the subtotal gastric resection has better functional results. This method does not cause as many late postoperative disorders as Billroth I and Billroth II operations. So, it is better to use the Rue-type anastomosis for treatment of distal stomach cancer stage I-III.

[Combined operations in cholelithiasis]. / Sochetannye operatsii pri zhelchnokamennoi bolezni.

Experience in combined operations for cholelithiasis on 162 patients is discussed. In 98 patients, cholecystectomy was performed as a simultaneous stage of surgical treatment, the main stage of the operation was gastrectomy or resection of the stomach for cancer in 26 patients, formation of a small stomach for alimentary-constitutional obesity in 19, various types of vagotomy in 33, hemicolectomy, resection of the colon and sigmoid intestine for malignant tumors in 10, and reconstructive manipulations on the stomach, correction of intestinal obstruction, and other operations in 10 patients. Cholecystectomy was the main stage of the operation in 48 patients with hernias, benign tumors of the uterine appendages, breasts, and soft tissues. The authors insist that cholecystectomy must be carried out when cholelithiasis is a concurrent disease; they showed that increase in the extent of the operative intervention had no essential effect on mortality and frequency of postoperative complications (mortality rate, 1.2%). The authors substantiate the expediency of performing combined operations from economical considerations--the economical effect of the operations conducted by the authors came to some 51,000 roubles.
