[Minimally invasive esophagectomy for benign esophageal diseases: results of a two-center study]. / Minimal'no invazivnaya ezofagektomiya pri dobrokachestvennykh zabolevaniyakh pishchevoda: rezul'taty dvukhtsentrovogo issledovaniya.

OBJECTIVE: To analyze the results of thoracoscopic esophagectomy for benign esophageal diseases. MATERIAL AND METHODS: The study included 78 patients who underwent thoracoscopic esophagectomy between 2011 and 2019. Peptic and burn strictures of the esophagus were diagnosed in 53 patients, achalasia - in 24 patients. Minimally invasive esophagectomy and esophagoplasty with isoperistaltic gastric tube and esophagogastrostomy on the neck was performed in 68 patients, Ivor Lewis esophagectomy - in 1 patient, coloesophagoplasty - in 9 patients. We used manual technique of anastomosis in 58 patients, stapling device - in 19 patients. In 1 case, surgery was finished with esophagostomy and gastrostomy. RESULTS: Mean blood loss was 200 ml (10-1200), surgery time - 450 min (265-765 min). Early postoperative complications occurred in 37 patients including anastomotic leakage in 24 cases. In long-term period, anastomotic strictures developed in 9 patients. No mortality was observed. CONCLUSION: Minimally invasive esophagectomy for benign esophageal diseases ensures favorable clinical outcomes. However, no consensus in the choice of surgical approach and indications, as well as small number of these patients cause challenges in implementation of this technique. There are different opinions regarding technique of anastomosis on the neck and surgical access in thoracoscopic esophagectomy.

IMMUNOMODULATORY EFFECT OF ALLOGENEIC MESENCHYMAL STEM CELLS OF RATS.

INTRODUCTION: Recently, more and more attracted the attention of cell therapy, which requires a study of the efficacy and safety of allogeneic MSCs transplantation in acute and chronic inflammatory reactions. The aim of our study was to examine the effectiveness of transplantation of allogeneic mesenchymal bone marrow stromal cells for the healing of surgical wounds the glandular stomach in rats. MATERIAL AND METHODS: Using white Wistar rats. Producing cell transplantation mononuclear fraction derived from rat bone marrow aspirate. Injected cells 8 and 9 th passage. The dose of cells administered to 3-th and / or 7-th days 3,5h106 cells / ml twice or 5,0h106 cells / ml dose. Autopsy on day 10-th and 17-th. The serum ELISA determined the content of the pro- and anti-inflammatory cytokines IL1ß, TNFα, IFNy, IL-4. RESULTS AND DISCUSSION: Introduction MSCs contributed to the decline of the immune mediators of inflammation IL1P, TNFa, IFNy, increase anti-inflammatory IL4. Quality improved healing. CONCLUSION: Rapid curative effect of stem cells may be associated with the formation of blood immune cells (macrophages) that produce substances that restore damaged tissue. They restore the balance between Th1 and Th2.

[Thoracolaparoscopic simultaneous operations on esophagus].

Extirpation or subtotal resection of esophagus was performed in 14 patients by using of thoracolaparoscopic technique in terms from November 2011 to March 2014. The mean patients' age was 56 years old (27-67 years). In 10 patients indications for surgery included benign esophagus diseases such as cardiospasm stage IV (2 cases), peptic stricture (5 cases) and burn stricture (3 cases). 4 patients were operated for esophagus cancer including middle one-third cancer in 1 patient, lower one-third cancer in 3 cases. 10 patients underwent extirpation of esophagus with peristaltic gastric tube plasty. 1 patient had esophagus substituted by segment of the left colon. Esophageal anastomoses were formed on the neck (interrupted sutures were applied in 7 patients; staplers - in 3 cases). Lewis operation with intrapleural esophageal-gastric anastomosis forming was performed in 3 patients. The mean surgery duration was 579 minutes (305-710 min), mean blood loss - 141 ml (from 50 to 300 ml). Postoperative period had not complications in 8 of 14 patients. Different complications including partial failure of the anastomosis on the neck (5 cases), intrapleural anastomosis failure (1 case) were observed in 6 patients. Partial failure of the anastomosis on the neck was treated by using of therapy. All patients recovered. Patient with intrapleural anastomosis failure required additional surgery which included uncoupling of anastomosis, esophagostomy on the neck and gastrostomy forming. This patient died from recurrent myocardial infarction. Thus the authors consider that complete thoracolaparoscopic technique provides precise preparation of esophagus and stomach, adequate lymphadenectomy with minimal blood loss and operative trauma. The results after these operations are comparable with those after open interventions. Thoracolaparoscopic simultaneous operations must be applied in clinics having sufficient experience in esophagus surgery and thoracolaparoscopic technique.

[Mesenteric inflammatory veno-occlusive disease is a rare nosological entity: Literature review and the authors' clinical observation].

Mesenteric inflammatory veno-occlusive disease (MIVOD) is a rare disease. Its basis is inflammation of the small and medium-sized mesenteric veins, which is generally complicated by thrombosis and intestinal ischemia. Arteries are not therewith involved in the process. According to the location, either ischemic jejunitis (ileitis) or segmental colitis develops. The etiology and incidence of MIVOD are unknown. Only a few tens of descriptions of clinical cases have been published. MIVOD is differentially diagnosed with Crohn's disease and vasculitides (Behçet's syndrome, Buerger's syndrome, rheumatoid arthritis, and systemic lupus erythematosus). The paper presents a MIVOD patient with partial thrombosis of portal, superior mesenteric and splenic veins, pylephlebitis, extrahepatic portal hypertension and with ischemic jejunitis complicated by fistulas, subcompensated stenosis, and seropurulent peritonitis. At laparotomy, an infiltrate with multiple interintestinal abscesses and a 40-cm jejunal segment with 4 fistular openings up to 1.5 cm in diameter and necrotic walls were removed and an interintestinal anastomosis was applied. A morphological examination of the operative material detected thrombi, stases, and pronounced plethora of the veins with fibrinoid changes in their walls. The lumen of arterial vessels of different diameters was free. No signs of systemic vasculitis and Crohn's disease were found. The postoperative period was uncomplicated.

[Cachexia and multiorgan insufficiency in a patient with small intestine carcinoid].

Carcinoid of the thin bowel is difficult to diagnose pathology. Complications diagnosticians with that doctors clash on ambulatory and hospital the stages, including at offtype clinical presentation of disease, result in late recognition of carcinoid and belated operative intervention. In taken apart case a diagnosis was set at pathomorphologic research. One of typical displays of carcinoid syndrome is a cachexy. Treatment of carcinoid is surgical, a conservative correction is sent mainly to the decline of hormones activity of this tumours type.

[Features of anesthesia in rats at abdominal operations].

Nowadays, in Russia, diethyl ether is the most popular narcosis for rodent and particular rats. We had tested the new methods based on Zoletil 100 + XylaVet (15 mg/kg and 15-10-5 mg/kg) respectively. 6 conventional female rats were treated with this narcosis. The rats, early have narcotized by diethyl ether were investigated as control group. All of 6 treated with new narcosis animals died in early post-operative time. Interestingly enough, that organ toxicity, except neurologic toxicity, was not described in literature and manuals. We assume that this new narcosis is the cause of portal thromboses.

[Endoscopic treatment of gastric varices bleeding].

The problem of prevention of variceal bleeding (VB) of esophagus and stomach in patients with portal hypertension has not lost its relevance due to the high mortality rates (reaching 50% at relapse), as a result of the objective difficulties of implementation of efficient primary hemostasis and subsequent control of recurrent bleeding and adequate correction of coagulopathy, and decompensated liver function. Endoscopic ligation of esophageal VB latex rings or plastic endo loop continues to be the standard prevention of bleeding of portal genesis (Baveno IV, V). However, according to several authors, endoscopic ligation by latex rings should not be used in the propagation of VB on the stomach (as well as the presence of VB isolated stomach) because of the danger of destruction latex by gastric juice. At the same time, the latex ligation is much easier technically, faster, and therefore, it is easier tolerated, and most importantly, do not poses a threat to the strain varices difficult to stop the bleeding which in some cases observed at tightening of the plastic endoloop. In this study proved the possibility to reach the comparative safety and efficacy of gastric banding Varices with latex rings.

[Results of 24-h pH monitoring in patients with gastroesophageal reflux disease before and after fundoplication].

AIM: To study informative value of 24-h pH monitoring in registration of gastroesophageal and duodenogastroesophageal reflux (GER, DGER) in patients with gastroesophageal reflux disease (GERD) before and after surgical treatment. MATERIAL AND METHODS: A total of 39 GERD patients after laparoscopic fundoplication entered the study: 12 (39%) males and 27 (61%) females, mean age 47.6 +/- 3.2 years. pH monitoring was made with domestic device Gastroscan-24 before operation and one year after it. Esophagogastroscopy and polypositional roentgenoscopy of the upper gastroduodenal tract were made also before operation and after 1-year follow-up. RESULTS: Before operation, mean pH in the gastric body was 1.7 +/- 1.28, De Meester index 40.4 +/- 8.91, esophageal acidity index (EAI) 22.3 +/- 1.59, the number of acid GER 59.2 +/- 9.41, number of DGER 14.3 +/- 3.47. After laparoscopic fundoplication--3.3 +/- 1.52, 8.7 +/- 5.71 (p < 0.05), 2.5 +/- 0.62 (p < 0.05), 24.4 +/- 8.6 (p < 0.05), 6.5 +/- 3.63, respectively. Five patients (12.8%) examined before the operation had clinicoendoscopic picture of GERD, but normal values of De Meester index and EAI. CONCLUSION: 24-h pH monitoring can estimate both gastroesophageal and duodenoesophagogastric refluxes, but esophageal and gastric pH monitoring only are not sufficient for decision on treatment policy. Such decision should be taken individually for each patient after the analysis of the results of complete clinical examination, symptoms and the disease history.

[Surgical treatment of neuromuscular diseases of the esophagus].

Surgical treatment of patients with neuromuscular diseases of the esophagus is a separate issue, and the approach to antireflux surgery they differ from fundoplication for gastroesophageal reflux disease. At the Central Research Institute of Gastroenterology in 2010 yr were 17 patients with neuromuscular diseases of the esophagus laparoscopic fundoplication. Analysis of results showed the effectiveness of laparoscopic fundoplication in patients with severe esophageal motility.

[Fundoplication as prophylaxis of reflux-esophagitis in patients with varicose esophageal veins].

AIM: To investigate the condition of esophageal mucosa (EM) before and after surgical and endoscopic treatment of varicose esophageal veins (VEV). MATERIAL AND METHODS: EM was examined in 100 patients (64 males and 36 females aged 33-74 years, mean age 528 +/- 5.7 years) with hepatic cirrhosis (HC). Of them, 80 patients have undergone endoscopic ligation of the esophageal veins, 20 patients--surgical disconnection of the azigoportal blood flow according to the original method with additional fundoplication. All the patients had intrahepatic portal hypertension caused by HC of different etiology. RESULTS: Before operation, 70% patients had inflammation-induced alterations of the EM of different severity. Endoscopic ligation of the esophageal veins did not change the rate of EM inflammation detection. In operated patients reflux-esophagitis was detected significantly less frequently. CONCLUSION: The above results show efficacy of fundoplication as a method of esophagitis prevention. Esophagitis is one of VEV hemorrhage risk factors. Fundoplication is not easy to make and is not indicated for all HC patients, especially in urgent situations. However, in case of decision to operate for prevention of VEV hemorrhage, it is advisable to conduct fundoplication.

The article is a an overview of the literature data on pathogenetic aspects of the development of reflux esophagitis, metaplasia, dysplasia, cancer of the esophagus after gastrectomy and partial gastrectomy in the experiment and clinical practice.

[Primary prevention of reflux esophagitis in achalasia of cardia].

Aim of the study was to compare the incidence of reflux esophagitis in patients with achalasia cardia after successful surgical treatment with balloon dilatation and ezofago-cardio-seromyotomy followed by fundoplication according toToupet type. The study included only those patients with eliminated symptoms of dysphagia. All patients were divided into two groups depending on the method of treatment. In the first group (20 patients) performed balloon dilatation, second group (20 patients)--laparoscopic ezofagocardioseromiotomiya followed by fundoplication according type Toupet. Results evaluated one year after the intervention. Revealed that the incidence of reflux esophagitis were significantly higher in group of patients after balloon dilatation, than in the group of operated patients--40 and 15% respectively (p < 0,05). Received results allow to reconsider approaches to the selection of treatment method of achalasia cardia in favor of laparoscopic ezofagocardioseromitomii with the formation of posterior cuff-type Toupet.

[Rises and falls of antireflux surgery].

The review of world literature highlights the evolution of antireflux surgery. Based on the literature review reflected the appropriateness of antireflux operations in the period of increasing prevalence of GERD complications with a view to their prevention, as well as the historical stages of fundoplication development. The failures and complications of antireflux operations depending on the choice of fundoplication and method of surgical access has been still interesting. The tendency to the preoperative examination of patients has been noted in recent world surgical practice as try to reduce the prevalence of postoperative failures.
