Background: Femoroacetabular impingement syndrome (FAI) is a complex, often post-traumatically developing impairment of the hip joint. It is characterized by ambiguous symptomatology, which makes early diagnosis difficult. Aim: The study was conducted to evaluate the applicability of a triaxial gyroscopic sensor in routine practice as an additional indication criterion for operative versus conservative treatment procedures. Methods: Ninety-two patients were included in the experimental retrospective study and 62 completed the examination. All patients signed informed consent. A gyroscopic sensor was placed on the right side of the pelvis above the hip joint and patients walked approximately 15 steps. Data were also evaluated while the patients climbed stairs. A complete clinical examination of the dynamics and physiological movements in the joint was performed. The data measured by the gyroscopic sensor were processed using differential geometry methods and subsequently evaluated using spectral analysis and neural networks. Results: FAI diagnosis using gyroscopic measurement is fast and easy to implement. Our approach to processing the gyroscopic signals used to detect the stage of osteoarthritis and post-traumatic FAI could lead to more accurate detection and capture early in FAI development. Conclusions: The obtained data are easily evaluated, interpretable, and beneficial in the diagnosis of the early stages of FAI. The results of the study show that this approach can lead to more accurate and early detection of osteoarthritis and post-traumatic FAI.

Platelet-rich plasma (PRP) is presently employed across various medical disciplines, including surgical specialties. It is primarily used in the healing of chronic wounds, burn medicine, tissue regeneration support, and scar correction as well as in other surgical and orthopedic indications. Wounds, in general, possess a pro-inflammatory biochemical environment characterized by high protease activity that diminishes the effective concentration of growth factors. In contrast, PRP serves as a source of growth factors and exhibits mitogenic, angiogenic, and chemotactic properties. PRP is a biological product defined as a portion of the autologous blood's plasma fraction with a higher than physiological platelet concentration. PRP is obtained through the centrifugation of blood samples collected from patients. The insights into the biology, mechanism of action, and classification of PRP presented in this review can assist medical professionals in orienting themselves and comprehending the possibilities of the clinical application of this therapy, which remains a subject of investigation and validation. This review summarizes up-to-date information regarding the use of PRP, primarily in burn and reconstructive surgery, plastic surgery, traumatology, and general surgery.

OBJECTIVE: In this experimental study, we aimed to determine whether platelet-rich plasma (PRP) is a suitable preservative for dermo-epidermal grafts. An additional objective was to investigate how long grafts can be stored without biological degradation. METHODS: We compared pig skin graft preservation using PRP versus saline solution and crystalloid Custodiol®, which is used for hypothermic preservation of organs for transplantation. Grafts (10 × 10 mm) were placed on gauze impregnated with one of the tested solutions, and stored for 3, 7, 11, and 15 days at a constant temperature of 4°C. We evaluated a total of 240 pig skin samples: 120 by histopathology and 120 by fluorescence optical microscopy. RESULTS: Overall, Custodiol® solution appeared to be the best medium for preservation of dermo-epidermal grafts, with beneficial properties manifested on days 7 and 11. Although we expected PRP to be a better preservative than saline, this was not confirmed by our results, as we found no significant difference between these two media. In fact, by day 3, the histopathological results were better with standard saline solution than with PRP. On day 15, with each tested solution, some samples showed histological changes that are incompatible with graft viability. CONCLUSION: Overall, Custodiol® appears to be the best medium for dermo-epidermal graft preservation. Moreover, the present findings suggest a maximum graft storage time of 11 days in all of the tested solutions. We do not recommend using grafts stored for 15 days, due to isolated signs of graft biodegradation with all solutions.

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.

Pneumoperitoneum jako nález na zobrazovacích vyšetřeních není vždy jasnou známkou perforační náhlé příhody břišní. Nález je nutné dát do souvislosti s klinickým stavem a obtížemi pacienta, jelikož se může jednat o spontánní či nechirurgické pneumoperitoneum. Tento stav je opakovaně popisován, avšak velice často opomíjen. V této práci přinášíme kazuistiku pacienta s nechirurgickým pneumoperitoneem, kde, ačkoliv bylo postupováno podle doporučení, nebyla nalezena očekávaná intraabdominální patologie vysvětlující obtíže pacienta.
Pneumoperitoneum as a finding on imaging examinations is not always a sign of acute abdomen due to gastrointestinal perforation. These findings must be viewed in connection with the clinical condition and personal history of each patient because they may also indicate a non-surgical or spontaneous pneumoperitoneum. This condition is repeatedly described but very often neglected. This paper presents the case report of a patient with non-surgical pneumoperitoneum where, despite proceeding according to the guidelines, no expected intra-abdominal pathology explaining the patient’s problems was found.

INTRODUCTION: Adhesions are the most common cause of long-term morbidity after abdominal surgery and most often cause various forms of intestinal passage disorders ranging from partial obstruction to complete, life-threatening intestinal obstruction. The aim of the present study was to evaluate the protective effect of intraperitoneally administered lipid emulsions on the formation of adhesions in larger animal model, as the lubricating effect of phospholipids and the mechanical barrier of the lipid component are combined with the anti-inflammatory effect of fish oil. METHODS: Thirty-one female domestic pigs were randomly divided into three groups. At the end of the surgical procedure, a lipid emulsion or saline solution was applied intraperitoneally. After 14 days, an independent macroscopic, histological and immunohistochemical evaluation of the adhesions were performed. RESULTS: Intraperitoneal administration of lipid emulsions significantly reduced the incidence of intra-abdominal adhesions. Microscopic examination demonstrated a significant reduction in the number of inflammatory elements and the amount of collagen in the adhesions, especially after administration of the fish oil-based emulsion. A simultaneous decrease in neovascularization was observed in the adhesions. Evaluation of the intestinal anastomosis did not reveal significant differences in healing between the groups. CONCLUSION: Intraperitoneal administration of lipid emulsions can reduce the development of postoperative intra-abdominal adhesions by the combined action of phospholipids as important lubricants and lipids as a mechanical barrier. Their effect is caused by a reduction in proinflammatory and profibrotic mediators. At the same time, intraperitoneal administration of lipid emulsions does not impair healing of the anastomosis in larger animal model.

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.
