This systematic review aimed to summarize the available data on the treatment of pulmonary contusions with exogenous surfactants, determine whether this treatment benefits patients with severe pulmonary contusions, and evaluate the optimal type of surfactant, method of administration, and drug concentration. Three databases (MEDline, Scopus, and Web of Science) were searched using the following keywords: pulmonary surfactant, surface-active agents, exogenous surfactant, pulmonary contusion, and lung contusion for articles published between 1945 and February 2023, with no language restrictions. Four reviewers independently rated the studies for inclusion, and the other four reviewers resolved conflicts. Of the 100 articles screened, six articles were included in the review. Owing to the limited number of papers on this topic, various types of studies were included (two clinical studies, two experiments, and two case reports). In all the studies, surfactant administration improved the selected ventilation parameters. The most frequently used type of surfactant was Curosurf® in the concentration of 25 mg/kg of ideal body weight. In most studies, the administration of a surfactant by bronchoscopy into the segmental bronchi was the preferable way of administration. In both clinical studies, patients who received surfactants required shorter ventilation times. The administration of exogenous surfactants improved ventilatory parameters and, thus, reduced the need for less aggressive artificial lung ventilation and ventilation days. The animal-derived surfactant Curosurf® seems to be the most suitable substance; however, the ideal concentration remains unclear. The ideal route of administration involves a bronchoscope in the segmental bronchi.

OBJECTIVES: Although sarcopenia is recognized as one of the risk factors for increased morbidity after resection for colorectal cancer, the question of the most appropriate way to identify and quantify it is still unresolved. MATERIAL AND METHODS: This is a retrospective unicentric study following patients undergoing elective resection of the rectum for carcinoma with available staging computed tomography (CT) of the trunk. Psoas muscle density (PMD) and its area relative to patient height psoas muscle index (PMI) at the level of inferior vertebral end plate of third lumbar vertebra (L3) were assessed using an initial staging CT scan of the trunk. Post-operative complications, evaluated according to the Clavien-Dindo classification, and blood samples on post-operative days (POD) 3 and 5 were also recorded in the study population. Patients were divided into groups with complicated and uncomplicated post-operative course, and observed parameters were then statistically compared. RESULTS: The correlation of PMI values with the development of post-operative complications was not confirmed in a data set of 206 patients. PMD values were found to be borderline statistically significant in patients with complicated post-operative course, while in the group of patients with severe complications (Clavien-Dindo III-IV), there was no statistically significant difference in PMI or PMD values. The same results were obtained when comparing patients with anastomotic leak (AL). It was confirmed that operations on the lower rectum are riskier for the development of post-operative complications. The secondary objective of our study regarding serum C-reactive protein (CRP) levels of 3rd and 5th POD gave us the answer in the form of cutoff values of 115.7 mg/L (3rd POD) and 76 mg/L (5th POD). CONCLUSION: PMD appears to be a promising tool for predicting post-operative morbidity in patients after rectal resection, but a clear consensus on the method of measurement, interpretation of results and cutoff values is needed. Lower rectal resections are burdened with a higher risk of post-operative complications, especially AL. Monitoring of CRP levels remains an important marker in the prediction of AL due to its negative predictive value.

Bochdalek's hernia is the most common congenital malformation of the diaphragm with a defect in its posterolateral part. Its clinical manifestation in adulthood is rare. It is often an incidental finding, and its diagnosis may be challenging. A high index of suspicion is necessary, especially in cases presenting with cardiopulmonary or abdominal symptoms and an ambiguous finding on the initial chest X-ray. We present a case of an asymptomatic 50-year-old male patient with a bulky left-sided Bochdalek's hernia. Surgical treatment was indicated, and a direct suture of the defect after reduction of the herniated greater omentum, transverse colon, and tail of the pancreas was performed from the upper midline laparotomy. The postoperative course was uneventful, and the patient was discharged on the fifth postoperative day. The management of adult patients with these kinds of hernias in both acute and chronic settings is discussed, and some recommendations are mentioned to minimize unnecessary pitfalls.

BACKGROUND: Blood loss during major abdominal surgery is an essential parameter in the evaluation of strategies aimed at reducing perioperative bleeding. However, blood loss quantification remains unreliable and inaccurate. The aim of this study was to compare several methods of blood loss quantification-visual estimation by surgeon and anesthesiologist, the gravimetric method, the calculation method with spectrophotometric measurement. The spectrophotometric measurement is considered as the most accurate method. METHODS: The study was designed as a prospective observational cohort single-center study. We analyzed 61 patients who underwent elective liver or pancreatic resection. The anesthesiologists' and surgeons' estimate of blood loss was based on a visual assessment. The gravimetric method was based on weighing the suction canister and surgical drapes before and after use. The basis of calculation method was anthropometric and hematological parameters, we used López-Picado's formula. The spectrophotometric method was based on the spectrophotometric determination of hemoglobin mass in the lost blood. We compared the methods using paired t-test, non-parametric Wilcoxon test and Bland-Altman analysis. RESULTS: Visual estimation by surgeons and anesthesiologists, gravimetric measurement, and calculation method were significantly different from spectrophotometric measurement at the significance level α = 0.05. All methods overestimated blood loss which was measured by spectrophotometric method. The estimate by surgeons was the closest to the spectrophotometric measurement, difference 68.7 ml (95% confidence interval [CI]: -129.3--8.2). CONCLUSIONS: We conclude that the estimate of blood loss by surgeons and anesthesiologists, as well as gravimetric method and calculation method are all significantly inaccurate in real surgical setting. We did not confirm the commonly accepted assumption that surgeons underestimate the blood loss. TRIAL REGISTRATION: The study was registered under the title " Blood Loss Quantification During Major Abdominal Surgery" at ClinicalTrials.gov with the registration number NCT05316649. Date of the first registration was 20/3/2022.

PURPOSE OF THE STUDY Femoroacetabular impingement syndrome is a complex, often post-traumatically developing impairment of the hip joint, characterized by ambiguous symptomatology, which makes early diagnosis diffi cult, especially in the early stages. Experimental retrospective study was carried out to evaluate the usability of a triaxial gyroscopic sensor in routine practice as an additional indication criterion for operative versus conservative treatment procedures. MATERIAL AND METHODS 92 patients were included in the retrospective study, and 62 completed the investigation. All patients signed informed consent. A gyroscopic sensor was placed on the right side of the pelvis above the hip joint, and the patients walked approximately 15 steps. Furthermore, an evaluation of the data during stair climbing and a complete clinical examination of the dynamics and physiological movements in the joint was carried out. Data measured with a gyroscopic sensor were processed using differential geometry methods and then evaluated using spectral analysis and neural networks. The proposed technique of diagnosing FAI using gyroscope measurement is a fast, easy-to-perform method. RESULTS Our approach in processing gyroscopic signals used to detect the stage of arthrosis and post-traumatically developing FAI could lead to more accurate early detection and capture in the early stages. CONCLUSIONS The obtained data are easily evaluated, interpretable and benefi cial in diagnosing the early stages of FAI. The results of the conducted research showed this approach to more accurate early detection of arthrosis and post-traumatically developing FAI.

Vojenská chirurgie je jedním ze základních oborů vojenské medicíny. Vychází z principů chirurgie prováděné v době míru, ale realizací za specifických podmínek se významně odlišuje. Cílem článku je popsat tyto odlišnosti a představit aktuální stav poskytování chirurgické péče v poli v podmínkách Armády České republiky. Zdravotnické zabezpečení v poli, resp. léčebně-odsunový systém zdravotnických služeb armád členských zemí NATO je organizován na čtyřech úrovních, kterým odpovídají zdravotnická zařízení označovaná jako Role 1−4. Poskytování chirurgické péče v polních podmínkách probíhá zpravidla na úrovni Role 2 a 3. Zatímco v podmínkách zahraniční vojenské mise směřuje chirurgická léčba k dosažení definitivního léčebného standardu, pak při typicky válečném konfliktu je jediným cílem záchrana života a končetin a příprava raněného vojáka k dalšímu odsunu. Důležitou součástí poskytování zdravotní péče v poli na jednotlivých úrovních je i třídění raněných, jehož význam narůstá zejména za situace jejich hromadného příjmu. V případě vojenské zdravotnické služby Armády České republiky jsou v rámci výstavby a rozvoje schopností definovány cíle, které by měly rozšířit a posílit současné možnosti poskytování chirurgické péče v poli – aktuálně to jsou dvě polní nemocnice schopné zabezpečit úrovně Role 2, ev. 3. Ambiciózní plán výstavby dalších polních zdravotnických prvků je reálně obtížně dosažitelný v předpokládaném časovém horizontu a navíc naráží i na výrazný nedostatek vojenských chirurgů vzhledem k plánovanému rozsahu navýšení kapacit. I přes všechny objektivní obtíže mají čeští vojenští chirurgové vysoký kredit v očích aliančních spojenců získaný během působení české polní nemocnice či samostatného polního chirurgického týmu v rámci mnohonárodních uskupení.
Military surgery is one of the basic branches of military medicine. It is based on the principles of surgery performed in peacetime, but is significantly different when performed under specific conditions. The aim of the article is to describe these differences and present the current state of providing surgical care in the field in the Czech Army. Medical support in the field, or the treatment and evacuation system of medical services of the armies of NATO member countries, is organized on four levels, matched by medical facilities designated as Role 1−4. Surgical care in the field usually takes place at the level of Role 2 and Role 3. While in the conditions of a foreign military mission, surgical treatment aims to achieve a definitive standard, in a typical war conflict the only goal is to save life and limb and prepare casualties for further evacuation. Additionally, triage of the wounded is an important part of health care in the field at individual levels, the importance of which increases especially in the case of mass casualties. In the military medical service of the Army of the Czech Republic, goals are defined as part of the construction and development of capabilities, which should expand and reinforce the current potential of providing surgical care in the field – currently encompassing two field hospitals capable of Role 2 or 3. The ambitious plan to construct additional field medical elements is difficult to achieve in the expected time horizon and, in addition, it also faces a significant shortage of military surgeons due to the planned scope of capacity increase. Despite all the objective difficulties, however, Czech military surgeons have a high credit in the eyes of the NATO allies, gained during the deployment of the Czech field hospital or of the Czech field surgical team within multinational military units.

Kolorektální trauma se v soudobých válečných konfliktech vyskytuje v 5–10 %. Nejčastější příčinou je střelné nebo střepinové poranění, kontuzně-lacerační mechanismus je ve válečné zóně ojedinělý. I přes moderní léčebné postupy je ale zatíženo vysokou mírou morbidity, zejména pokud není včas diagnostikováno a léčeno. Management chirurgické léčby upřesňují jednoduchá skórovací schémata – colon injury scale, rectal injury scale a Flintův skórovací systém. Resekční výkony tračníku s primární nebo odloženou anastomózou nemají vyšší riziko komplikovaného hojení a v dnešní době jsou upřednostňovány před konstrukcí terminálních stomií. Ty jsou indikovány při závažné oběhové nestabilitě při hemoragicko-traumatickém nebo septickém šoku s pokročilou difuzní peritonitidou. K traumatu intraperitoneálního segmentu rekta se přistupuje stejně jako k tračníku. Poranění extraperitoneálního rekta bez devastace měkkých tkání může být ošetřeno transanální suturou nebo i bez ní. Naopak devastující poranění rekta spolu s měkkými tkáněmi pánve se mají primárně zajistit derivační stomií a odloženou rekonstrukcí. Presakrální drenáž nebo laváž rekta již nejsou doporučovány.
The rate of colorectal trauma is 5–10 % in modern war conflicts. The most common causes include gunshots or shrapnel injuries; the contusion-laceration mechanism occurs in sporadic cases in the war zone. Despite modern surgical procedures, however, it is associated with a high rate of morbidity, especially if it is not diagnosed and treated in time. Surgical management is specified by simple scoring schemes – the colon injury scale, rectal injury scale and the Flint grading system. Colonic resection with primary or delayed anastomosis is not associated with a higher risk of complicated healing and is nowadays preferred over the construction of terminal stomas. These are indicated only for cases with severe hemodynamic instability in traumatic-hemorrhagic or septic shock with severe diffuse peritonitis. Trauma to the intraperitoneal segment of the rectum is treated in the same way as trauma to the colon. An extraperitoneal rectal injury without soft tissue devastation can be treated with or without a transanal suture. On the contrary, devastating injuries to the rectum including the pelvic soft tissues should be primarily controlled with a stoma with delayed reconstruction. Presacral drainage or rectal stump lavage are no longer recommended.

PURPOSE: The aim of this experimental study was to test the method of prevention of postoperative complications, especially infectious, in partial dehiscence following stapler anastomosis in rectal surgeries. METHODS: The method includes the application of a hyaluronic acid-based gel in combination with triclosan, which has antibacterial properties. The gel was applied to the space around the rectum with an artificial, precisely defined dehiscence so that the dehiscence was separated from the rest of pelvis and the peritoneal cavity to avoid the spread of infection. The study included 30 female pigs. The rectosigmoid colon was mobilized and transected completely. Anastomosis was constructed with circular staplers. A perforator was then used to create precisely defined artificial dehiscence. Subsequently the lesser pelvis was filled with hyaluronic gel such that the site of artificial dehiscence was covered completely. RESULTS: All animals survived for 14 days until the second-look revision with no signs of failure in the anastomosis healing, local inflammation, and sepsis or postoperative complications, such as chills, refusal of liquid or feed, abdominal distension, and bowel obstruction. CONCLUSION: Hyaluronic acid applied as a precursor solution around the rectal anastomosis fills the lesser pelvis perfectly. It prevents the leakage of intestinal contents in the lesser pelvis. Triclosan as an antibacterial substance prevents the spread of inflammation in the pelvis or even in the abdominal cavity.

INTRODUCTION: The inflammatory process in Crohn's disease (CD) is closely associated with the formation of reactive oxygen species. Antioxidant enzymes can play an important role in the outcome of CD and may influence postoperative recurrence in these patients. The aim of our study was to evaluate gene expression of intracellular antioxidant enzymes in surgically resected intestinal specimens of patients with CD, both in macroscopically normal and in inflamed tissue. METHODS: A total of 28 patients referred for elective bowel resection were enrolled in the study. Full-thickness small intestinal specimens were investigated. Gene expression of antioxidant enzymes - superoxide dismutase (SOD), glutathione peroxidase (GPX), glutathione reductase (GSR) - was evaluated both in macroscopically normal and inflamed samples. RESULTS: There were significantly lower levels of SOD1 mRNA (p = 0.007) and GSR mRNA (p = 0.027) in inflamed tissue compared to macroscopically normal areas. No significant differences were found between affected and non-affected intestinal segments in mRNA for SOD2, SOD3 and GPX. CONCLUSIONS: Our pilot data clearly showed that the gene expression of major antioxidant enzymes is not a uniform mechanism in the pathogenesis of Crohn's disease. Topically decreased gene expression of SOD1 and GSR might facilitate the segmental tissue injury caused by reactive oxygen species.
