Purpose Laparoscopic sleeve gastrectomy (LSG) is currently the most common bariatric surgery in the world. Although it appears to be a safe treatment for obesity, it is still at risk of complications. The latest literature shows that postoperative bleeding occurs in 2–4% of cases, and up to 3% of cases requires reoperation for hemostasis. The aim of the study is to assess the effect of tranexamic acid (TXA) on hemorrhagic events and the reoperation rate in patients undergoing LSG. Methods The study was designed as a retrospective analysis of patients undergoing LSG. We investigate the patients 6 months before and 6 months after introducing the prophylaxis doses of TXA into our bariatric protocol (non-TXA group vs TXA group). Results Three hundred fourteen patients underwent LSG in a high-volume center from 2016 to 2017. After introducing TXA, a statistically significant reduction in the incidence of hemorrhage during surgery was observed (22.3% vs 10.8%, p = 0.006). There was a statistically significant reduction in the need for the staple line oversewing (10.2% vs 1.9%, p = 0.002). The mean operating time and the mean length of hospital stay were significantly higher in the non-TXA group than TXA group (63.1 vs 53.7 min, p < 000.1; 2.3 vs 2.1, p = 0.02). In both groups of patients, no venous thromboembolism or other complications occurred within 6 months after the surgery. Conclusions The prophylactic doses of TXA may be useful in reducing the hemorrhagic events during LSG. It may also shorten the length of hospital stay and the operating time.

Introduction: Diseases of the respiratory system are the third cause of mortality worldwide in terms of incidence. A spirometry test enables early detection of changes in the respiratory tract of persons with minor ailments, as well as the diagnosis of a fairly advanced illness whose symptoms have been neglected by the patient. Aim: The aim of this study has been to identify any irregularities in spirometry tests in the population of the province of Warmia and Mazury. Material and methods: The study covered 1061 persons living in the province of Warmia and Mazury, of which 637 patients (188 women and 249 men) were included in the analysis. The participants provided their basic demographic and medical data through a survey. Each participant underwent a spirometry test according to the European Respiratory Society and American Thoracic Society 2005 guidelines. Statistical analysis was carried out in a Statistica software package. Results and Discussion: The study showed that women smoke significantly less than men – the average pack years for women and men were 4.02 (SD 9.33) and 8.11 (SD 17.19) (P < 0.001), respectively. A higher number of pack years contributed to a higher incidence of the respiratory tract symptoms (cough, wheeze, breathlessness) (P < 0.05). Compared to men, women were more often observed to suffer from grade 1 or 2 degree dyspnoea on the mMRC scale. Conclusions: Pulmonary function tests play an important role in the diagnosis of respiratory system diseases. Promotion of prophylactic measures in streets of cities helps to improve patients’ awareness of the condition of their health.
