Оперативное лечение различных заболеваний кишечника сопровождается осложнениями в виде нарушений микроциркуляции в области анастомоза кишки. Ранее нами показана способность лимфостимуляторов пептидной природы восстанавливать нарушенную микроциркуляцию, что послужило основой для настоящего исследования. Цель работы - оценка влияния стимуляции лимфотока в стенке кишки на процессы восстановления микроциркуляции, структуры и функции тонкой кишки в области оперативного вмешательства. Методика. В экспериментах на наркотизированных крысах (хлоралгидрат в дозе 0,6 г/кг в 0,9% растворе NaCl) моделировали различные поражения тонкой кишки (наложение лигатуры, перевязка 1-3 брыжеечных артерий, перекрут петли кишки вокруг оси брыжейки, сочетание нескольких видов повреждений). Резекция поврежденного участка через 1 сут. с последующим созданием тонкокишечного анастомоза завершалась орошением операционного поля раствором пептида-стимулятора лимфотока (40 мкг/кг массы животного в 1 мл 0,9% раствора NaCl). На 7-е сут. после операции проводили гистологическое исследование фрагмента кишки в области анастомоза. Результаты. На 7-е сут. после резекции у выживших животных (летальность вследствие кишечной непроходимости составляла 30%) имеют место морфологические признаки острых сосудистых нарушений стенки кишки, изменений кровеносных и лимфатических микрососудов, интерстициальный отек всех слоев стенки кишки, дилатация просвета кишки, повреждение всасывающего эпителия ворсин с истончением щеточной каемки клеток, морфологические признаки гиперфункции бокаловидных клеток. Использование лимфостимулятора пептидной природы после операции увеличивало выживаемость животных на 24%. У части животных отмечалось уменьшение расширения просвета кишки, у других практически полная его нормализация. Восстанавливалась форма кишечных ворсин и распределение бокаловидных клеток. Отсутствовали признаки внутриклеточного и межмышечного отека. Отмечено умеренное полнокровие венул. Заключение. Использование лимфостимулятора при хирургическом лечении кишечной непроходимости увеличивает выживаемость животных на 24% по сравнению с контролем, способствует более раннему восстановлению структуры и функции тонкой кишки. Полученные результаты свидетельствуют о перспективности использования стимуляции лимфотока при операциях на кишечнике. Surgical treatment of bowel diseases is associated with complications that cause microcirculatory disturbances in the anastomosis area and may lead to a fatal outcome. This study was based on our previous finding that peptide-type lymphatic stimulators are able to restore impaired microcirculation. The aim of this work was stimulating the lymph flow in the intestinal wall to facilitate recovery of microcirculation, structure and function of the small intestine in the area of surgical intervention. Methods. In experiments on anesthetized rats (0.6 g/kg chloral hydrate in 0.9% NaCl), various small bowel lesions were modeled (bowel ligation, ligation of 1-3 mesenteric arteries, gut torsion, combination of several lesion types). In 24 h, the damaged area was resected, and a small intestine anastomosis was creased. The surgery was completed with irrigation of the operative field with a solution of lymph flow stimulating peptide (40 мg/kg body weight in 1 ml of 0.9% NaCl). A gut fragment from the anastomosis area was examined histologically on day 7 after the surgery. Results. On the 7th day after removing the intestinal obstruction, the surviving animals (lethality 30%) had morphological signs of acute vascular disorders in the intestinal wall; changes in blood and lymphatic microvessels; interstitial edema of all intestinal wall layers; dilatation of the intestinal lumen; damage to the absorptive epithelium of villi with thinning of the brush border, and hyperfunction of mucous (goblet) cells. The use of the peptide after surgery increased the survival rate of animals by 24% and provided a smaller dilatation of the intestinal lumen in some animals. In other animals, the lumen recovered. The shape of intestinal villi and distribution of goblet cells were restored. Signs of intracellular and intermuscular edema were absent. Moderate venular congestion was noticed. Conclusion. Using the lymphatic stimulator in surgical treatment of intestinal obstruction increases the survival rate of animals by 24% compared to the control, facilitates earlier restoration of the small intestine structure and function. The obtained results indicated the effectiveness of lymphatic stimulation in intestinal surgery.

The aim of this study was to evaluate prevalence of chronic rhinosinusitis (CRS) and nasal polyps in adult patients with cystic fibrosis (CF) in Russian Federation. Additionally, we investigated the clinical course of CRS and developed the optimal therapeutic strategy.Methods. Three hundred and forty eight CF patients were involved in the study. Physical examination, computed tomography (CT) of paranasal sinuses and audiometry, if needed, were used. CRS and bilateral nasal polyps were diagnosed in 28 patients. Nasal endoscopy, SNOT-20 questionnaire, rhinomanometry, micro - biological examination of sputum and mucus from paranasal sinuses (obtained during puncture or surgery), spirometry, and measurement of serum markers of inflammation were used. Endoscopic sinus surgery was used in 14 patients (the group 1) and others were treated non-surgically (the group 2). Both group were treated during 6 months using intranasal mometasone, mucolytics and antibiotics via PARI SINUSTM nebulizer.Results. An improvement in symptoms, CT signs, rhinomanometry parameters and endoscopic signs was seen in both groups after treatment and was more prominent in the surgical treatment group compared to the non-surgical treatment group. Bacterial load reduction in nasal sinuses, decrease in the rate of pulmonary disease exacerbations, and an improvement in oxygen blood saturation were found in the surgical treatment group only. Treatment of CRS did not affect lung function, sputum microbiology and serum inflammatory markers.Conclusion. Endoscopic sinus surgery followed by intranasal mucolytics and antibacterials is an effective and well-tolerated treatment in adult CF patients with CRS.

Background Endoscopic sinus surgery is performed for many reasons, most commonly for chronic rhinosinusitis refractory to medical treatment. A paradoxical middle turbinate is an anatomic variant that can hinder endoscopic access to the sinuses. No publication has addressed how to surgically treat a paradoxical middle turbinate. Method We present a basic endoscopic surgical approach to conservatively resect a paradoxical middle turbinate in order to improve access to the middle meatus and the sinuses while preserving support and function. Conclusion Conservative remodeling of the paradoxical middle turbinate can provide access to the sinuses while maintaining a significant portion of the middle turbinate.

OBJECTIVE: The aim of this study was to investigate mucin expression in chronic sinusitis compared to that in normal nasal mucus. STUDY DESIGN AND SETTING: Sinus mucus samples were collected during functional endoscopic sinus surgery (FESS). The expression of 3 airway mucins, MUC2, MUC5AC, and MUC5B, was determined by ELISA. RESULTS: The 3 mucins are expressed in chronic sinusitis and in normal nasal mucus. MUC5AC and MUC5B represent a major component in sinus mucins while MUC5B and MUC2 predominated in normal nasal mucin. In sinus mucins, upregulation of MUC5AC was associated with downregulation of MUC2 and vice versa. This inverse relationship was strengthened in the presence of nasal polyps. CONCLUSION: At least 3 mucins are expressed at various levels in chronic sinusitis. An inverse relationship was identified between expression of MUC5AC and MUC2. Large prospective studies are required to unravel the complexities of sinus mucus in chronic sinusitis. SIGNIFICANCE: Mucins may be used as markers for assessment of disease severity and may also help as prognostic indicators following medical or surgical treatment.

Introduction. In spite of the numerous studies devoted to the issues of chronic rhinosinusitis with nasal polyps, the urgency of this problem remains due to the high incidence of the disease. The relapsing course of chronic rhinosinusitis with nasal polyps determines the uncontrolled course of bronchial asthma by patients with combined pathology. The main goal of case management of patients with chronic rhinosinusitis with nasal polyps is to achieve control over the polyposis process. It has been shown, that a promising direction is the study of biological markers. Goal. Study of the concentration of serum periostin in combination with serum eosinophilia and the number of eosinophils of the nasal secretion to predict early recurrence of chronic rhinosinusitis with nasal polyps after surgical treatment.Materials and methods. The study included 47 patients with a diagnosis of chronic rhinosinusitis with nasal polyps and chronic rhinosinusitis with nasal polyps in combination with bronchial asthma. All patients underwent bilateral endoscopic polysinusotomy followed by case follow-up for a year. The diagnosis of bronchial asthma was made based on the diagnostic criteria defined in the Global Strategy for the Treatment and Prevention of Bronchial Asthma and in the Federal Clinical Guidelines for the Diagnosis and Treatment of Bronchial Asthma. All patients were consulted by a pulmonologist. Control examinations of patients were carried out every 3 months. All patients underwent a study of the concentration of periostin in the blood serum. Blood probe samples were taken before the start of treatment and after 12 months.Results and discussion. In the course of the study, was proved the relationship between a high concentration of serum periostin in combination with increased eosinophils of blood and nasal secretion with an early relapse of polyposis rhinosinusitis.Conclusions. An increased concentration of serum periostin before surgical treatment is a prognostically unfavorable factor for early recurrence of chronic rhinosinusitis with nasal polyps.

ObjectivesTo explore general practitioner (GP) and ears, nose and throat (ENT) specialist perspectives of current treatment strategies for chronic rhinosinusitis (CRS) and care pathways through primary and secondary care.DesignSemi-structured qualitative telephone interviews as part of the MACRO programme (Defining best Management for Adults with Chronic Rhinosinusitis)SettingPrimary care and secondary care ENT outpatient clinics in the UK.ParticipantsTwelve GPs and 9 ENT specialists consented to in-depth telephone interviews. Transcribed recordings were managed using NVivo software and analysed using inductive thematic analysis.Main outcome measuresHealthcare professional views of management options and care pathways for CRS.ResultsGPs describe themselves as confident in recognising CRS, with the exception of assessing nasal polyps. In contrast, specialists report common missed diagnoses (eg, allergy; chronic headache) when patients are referred to ENT clinics, and attribute this to the limited ENT training of GPs. Steroid nasal sprays provide the foundation of treatment in primary care, although local prescribing restrictions can affect treatment choice and poor adherence is perceived to be the causes of inadequate symptom control. Symptom severity, poor response to medical treatment and patient pressure drive referral, although there is uncertainty about optimal timing. Treatment decisions in secondary care are based on disease severity, polyp status, prior medical treatment and patient choice, but there is major uncertainty about the place of longer courses of antibiotics and the use of oral steroids. Surgery is regarded as an important treatment option for patients with severe symptoms or with nasal polyps, although timing of surgery remains unclear, and the uncertainty about net long-term benefits of surgery makes balancing of benefits and risks more difficult.ConclusionsClinicians are uncertain about best management of patients with CRS in both primary and secondary care and practice is varied. An integrated care pathway for CRS is needed to improve patient management and timely referral.

Endoscopic sinus surgery is a treatment method for chronic rhinosinusitis not controlled with medical treatment. It had started with functional endoscopic sinus surgery and the concept of reboot approach was introduced recently. For safe surgical treatment, understanding the anatomy especially personal variations between well-known structures is important. The practical points of surgical concept during endoscopic sinus surgery was suggested.
