RESUMO
Simultaneous pancreas-kidney transplantation (SPKT) aimed at increasing the life expectancy for diabetic patients with end-stage kidney disease (ESKD). However, the risks of surgery complications and immunosuppression therapy make it unclear if the SPKT positively impacts patient's quality of life (QoL). Using the Kidney Disease Quality of Life-Short-Form Health Survey (KDQOL-SF36) and Problems Areas in Diabetes (PAID) measurement tools, we compared the QoL of 57 patients on the pretransplant waiting list with that of 103 patients who had undergone SPKT. Posttransplantation patients were assessed within different time intervals (<1, 1-3, and >3 years). Mean KDQOL-SF36 scores were better among posttransplantation patients in the SF36 and KDQOL domains. It was also observed patients' stress reduction in PAID mean score (P = 0.011) after SPKT. We concluded that patients receiving SPKT had a better perception of QoL than did patients on the waiting list, and this positive perception remained almost entirely comparable over the three different intervals of the posttransplantation time. These positive results showed better outcomes when excluding patients that lost pancreas graft function. Further research is needed to compare diabetic patients with kidney transplant alone using specific measurement tools to evaluate patient's QoL.

Objective: Rheumatoid arthritis causes inflammation, pain, and joint degradation, necessitating treatment with anti-inflammatory drugs and corticosteroids, posing various challenges. We aimed to evaluate the effects of photobiomodulation (PBM) at two different doses associated to platelet-rich plasma (PRP) in an in vivo model of induced acute arthritis in Wistar rats' knee. Methods: Eighty-four Wistar rats were assigned into seven groups, including animals treated with PBM and/or PRP. On day 0, arthritis was induced in sham and treated groups through the intra-articular injection of zymosan (200 µg). Twenty-four hours after induction, the PBM groups were treated with an AsGaAl laser, whereas the PRP-treated groups received intra-articular injections with a concentration of 8 × 105 platelets obtained from another four animals. After 3 days, the animals were euthanized, and the interleukin (IL)-6 and complement C3 gene and protein expression levels were analyzed. Statistical analysis was performed using the mean ± SD with analysis of variance and Tukey's posttest, with a significance level set at 5% (p < 0.05). Results: Synovial inflammation decreased in PBM-treated groups; however, PRP alone showed no significant difference. Gene expression analysis revealed a significant difference in IL-6 and C3 levels in the PBM and PBM+PRP-treated groups. Meanwhile, the PRP alone group exhibited significance for IL-6. Moreover, the PBM and PBM+PRP-treated groups showed a significant difference in C3 protein expression levels, whereas the PRP alone group showed no difference. Conclusion: The increase in cellular activity in the synovial membrane and the decrease protein expression levels are owing to the reduction in proinflammatory mediators following PBM therapy.
RESUMO
PURPOSE: To evaluate morphological aspects and inducible nitric oxide synthase (iNOS) gene and protein expression in a model of acute inflammation. METHODS: Thirty-six female Wistar rats were assigned into three groups: control (saline, n = 12), sham (arthritis, n = 12), and PBM (arthritis and photobiomodulation, n = 12). Arthritis induction was performed with 200 µg of intra-articular Zymosan in sham and PBM animals. PBM was performed 24 h after induction with a laser device (λ = 808 nm, 25 mW of nominal power, fluence of 20 J/cm2, beam area of 0.02 mm2, time of 33 s, total energy of 0.825 J) with punctual and single dose application. Morphological analysis of joint structure (HE) and immunohistochemistry (anti-iNOS antibody) were performed on knee samples, and synovial tissue was submitted to RNA extraction, cDNA synthesis and gene expression analysis by quantitative polymerase chain reaction. Statistical analyses were performed with p < 0.05. RESULTS: It was observed an increase in the thickness of the synovial lining epithelium and inflammatory infiltrate in sham compared to PBM. Gene expression analysis showed higher iNOS expression in PBM, and iNOS protein expression decreased in PBM compared to sham. CONCLUSIONS: Photobiomodulation decreased inflammation in PBM animals, upregulated iNOS gene expression, however down egulated protein expression compared to sham.

Background: The assessment of health-related quality of life (QoL) has improved the treatment of gastric cancer. Aiming to compare the influence of skilled surgeons in general hospitals versus specialized hospitals in cancer in Brazil, this study evaluated the relationship between quality of life and types of hospitals (general or cancer) in treating patients with gastric adenocarcinoma operated by surgeons with specific training in Surgical Oncology. Methods: This was a cross-sectional study involving 104 patients. Inferential analyses were used to compare two Brazilian general hospitals and a cancer center, evaluating scores of the SF-36 and FACT-Ga QoL questionnaires (Kruskal-Wallis test, Mann-Whitney test); gender, smoking, and Helicobacter pylori tests status (Pearson's Chi-Square test); ethnicity, alcoholism, location of the tumor in the stomach, Lauren's histological types, and type of surgery (Fisher's exact test), number of lymph nodes resected by Surgical Oncologists [Analysis of Variance (ANOVA) with a Fixed Factor], and comparative survival analysis (Log-Rank test). Results: Patients treated at a cancer hospital had higher scores of the FACT-Ga (FACT-G total score, P=0.023; physical well-being, PWB, P=0.006; and functional well-being, FWB, P=0.011). The mean scores of the SF-36 questionnaire showed similar behavior but without reaching a significant difference. Patients operated by Surgical Oncologists at the cancer hospital had better scores in emotional well-being FACT-Ga domain (EWB, P=0.034 and P=0.047) compared to those operated by Surgical Oncologists in general hospitals. There was no significant difference in survival among the three hospitals (P=0.214). Conclusions: In this study, it was possible to suggest the relationship between QoL assessment scores with the centralization of care at specialized cancer hospital in the treatment of patients with gastric adenocarcinoma undergoing surgery with curative intent in Brazil.
RESUMO
Background: Cholelithiasis is currently one of the most common diagnosis in Brazil. The aim of this study was to validate the Gastrointestinal Quality of Life Index (GIQLI) as a quality-of-life (QoL) assessment among the Brazilian population with syntomatic gallstone. Materials and Methods: The questionnaire was translated and culturally adapted after the linguistic validation process determined by the international methodology. Sixty-three patients who underwent laparoscopic cholecystectomy responded to the GIQLI-Brazil and Short-Form Health Survey (SF-36) instruments. For the evaluation of reproducibility, 30 patients responded to GIQLI-Brazil two more times after 2 and 4 weeks. After the University of São Paulo Ethics Commitee Board approval (UNIFESP/CEP: 1270/2019), the study was carryed out between May 2019 and February 2020 at the Gastroenterology outpatient clinic of Hospital São Paulo-Federal University of São Paulo (UNIFESP). Cronbach's alpha, the calculation of the intraclass correlation coefficient (ICC), and Spearman's correlation were used to assess the validity and reproducibility of the instrument translated into Portuguese, and to measure correlation between the domains of the GIQLI-Brazil and SF-36 (P < .05). Results: Seven questions were modified during the process of translation and cultural adaptation. The Brazilian version of the instrument presented a Cronbach's alpha of 0.89, and excellent reproducibility through the ICC, with the following variation between domains: meteorism (ICC = 0.918; P < .001) and gastrointestinal function (lower tract) (ICC = 0.956; P < .001). The dimensions of the GIQLI-Brazil and SF-36 demonstrated a significant correlation (P < .001), except between the domains: functional aspects of the SF-36 and gastrointestinal function (lower tract) of the GIQLI-Brazil (r = 0.211). Conclusion: The GIQLI was translated and validated for Portuguese-Brazil and can be used to assess the QoL of adult patients with gastrointestinal diseases and/or disorders.

PURPOSE: Simultaneous pancreas-kidney transplantation (SPKT) brings several benefits for insulin-dependent type-1 diabetic patients associated with end-stage renal disease (ESRD). However, data on psychological outcomes for the waiting list and the transplanted patients are still lacking. METHODS: Using the psychological Beck inventories of anxiety (BAI) and depression (BDI), 39 patients on the waiting list were compared to 88 post-transplanted patients who had undergone SPKT. RESULTS: Significant differences were found regarding depression (p = 0.003) but not anxiety (p = 0.161), being the pretransplant patients more vulnerable to psychological disorders. Remarkable differences were observed relative to the feeling of punishment (p < 0.001) and suicidal thoughts (p = 0.008) between the groups. It was observed that patients who waited a longer period for the transplant showed more post-transplant anxiety symptoms due to the long treatment burden (p = 0.002). CONCLUSIONS: These results demonstrated the positive impact of SPKT on psychological aspects related to depression when comparing the groups. The high number of stressors in the pretransplant stage impacts more severely the psychosocial condition of the patient.

Background: One-anastomosis gastric bypass (OAGB) is a simpler procedure than Roux-en-Y gastric bypass (RYGB); however, biliary reflux can occur and impair outcomes. This study aimed to compare outcomes of OAGB and RYGB. Methods: Twenty patients with morbid obesity were randomized prospectively into two groups: OAGB (n=10) or RYGB (n=10). Quality of life (36-item short-form health survey [SF-36]), satisfaction (Visick scale), and body mass index (BMI) were evaluated before and 6 months after the operation. All patients underwent esophagogastroduodenoscopy with gastric and esophageal mucosal biopsies at 3 and 6 months after their operation. Results: The study found no significant difference in BMI before surgery (OAGB, 43.2 kg/m2; RYGB, 43.1 kg/m2; P=0.90) or at 6 months postoperative (OAGB, 32.1 kg/m2; RYGB, 31.8 kg/m2; P=0.91). There was no significant difference in improvement of quality of life (four SF-36 domains) or satisfaction (P=0.08) between groups at 6 months. There was no statistical difference between gastric (P=0.10) and esophageal (P=0.76) inflammation grade at three or 6 months between the two groups. Conclusion: OAGB and RYGB are equally effective in terms of weight loss, patient satisfaction, and quality of life improvement at 6 months after the procedures. Inflammation grade and cellular damage in the gastric pouch and in the esophagus were similar.
RESUMO
In Brazil, gastric cancer is the third most common type of cancer among men and fifth among women, with an estimated 13360 new cases among men and 7870 among women each year during the 2020-2022 period. This study presents reflections and attempts to add knowledge to the theme of quality of life (QoL) in patients with gastric adenocarcinoma and describes some of its characteristics in three regions of Brazil, with an evaluation of the disease's impacts in various dimensions of life, as reported by the patients themselves. We performed a narrative review of the literature and a data analysis of studies on QoL in Brazilian patients treated for gastric adenocarcinoma from three different cities in three geographic regions: Brasília (the midwest), Jaú (the southeast), and Macapá (the north).
RESUMO
OBJECTIVE: To analyze abdominal drain on the first postoperative day and evaluate its predictive nature for the diagnosis of Pancreatic Fistula exclusion, seeking to establish a cutoff point from which lower values demonstrate safety in excluding the possibility of this complication. METHODS: From August 2017 to June 2020, data from 48 patients undergoing pancreatic resection were collected and analyzed from a prospective cohort. The patients were divided into two groups, one group consisting of patients who did not develop PF (Group A), and the other composed of patients who developed PF (Group B). The receiver operation characteristic curve was constructed, and cutoff points were evaluated by calculating sensitivity and specificity. RESULTS: Group A brought 30 patients together (62.5%) and Group B brought 18 patients together (37.5%). The 444 U/L value was the most satisfactory cutoff point for the receiver operation characteristic curve (CI 0.690-0.941), with a sensitivity of 94.4% and a specificity of 60%, thus being able to select 18 of 30 patients who did not succumb to PF. CONCLUSIONS: Abdominal drain on the first postoperative day can be used as a predictive factor in the diagnosis of PF exclusion (CI 0.690-0.941), with the value of 444 U/L being the best performance cutoff point.

PURPOSE: To analyze gene and protein expression of metalloproteinases 1, 2, 9, 11 and 16 and their correlation with clinicopathological variables in colorectal adenocarcinoma. METHODS: A retrospective study of 114 patients with colorectal adenocarcinoma treated surgically in the period 2006 to 2008 in Hospital de Câncer de Barretos - Fundação Pio XII. The evaluation of gene expression was performed by RT-PCR, and protein by immunohistochemistry. The analysis of gene expression was classified as overexpressed genes and poorly expressed (fold change of approximately 2, p<0.05). The positivity of the markers in the immunohistochemical study was performed by semi-quantitative analysis. The tissue of TMA (Tissue Microarray) was done by two independent pathologists. RESULTS: The gene expression validated by immuno - histochemical was MMP-1(p= 0.00 and 1.57 fold change) and MMP - 2 (p= 0.01 and - 1.84 to fold change) when correlated with the histological types mucinous and adenocarcinoma NOS, MMP9 (p=0.01 and fold change of 1.13) and MMP-16 (p=0.03 and 1.61 fold change) when compared with the histological types villous and adenocarcinoma NOS, MMP - 11 statistically significant in relation to male (p = 0.04 and 1.65 fold change). CONCLUSIONS: The MMPs 1, 2, 9, 11 and 16 gene and protein expression with statistical significance in at least one of the clinicopathological variables studied. Thus, we conclude that these MMPs have potential as a prognostic factor in colorectal adenocarcinoma.

Purpose: To evaluate morphological aspects and inducible nitric oxide synthase (iNOS) gene and protein expression in a model of acute inflammation. Methods: Thirty-six female Wistar rats were assigned into three groups: control (saline, n = 12), sham (arthritis, n = 12), and PBM (arthritis and photobiomodulation, n = 12). Arthritis induction was performed with 200 µg of intra-articular Zymosan in sham and PBM animals. PBM was performed 24 h after induction with a laser device (λ = 808 nm, 25 mW of nominal power, fluence of 20 J/cm2, beam area of 0.02 mm2, time of 33 s, total energy of 0.825 J) with punctual and single dose application. Morphological analysis of joint structure (HE) and immunohistochemistry (anti-iNOS antibody) were performed on knee samples, and synovial tissue was submitted to RNA extraction, cDNA synthesis and gene expression analysis by quantitative polymerase chain reaction. Statistical analyses were performed with p < 0.05. Results: It was observed an increase in the thickness of the synovial lining epithelium and inflammatory infiltrate in sham compared to PBM. Gene expression analysis showed higher iNOS expression in PBM, and iNOS protein expression decreased in PBM compared to sham. Conclusions: Photobiomodulation decreased inflammation in PBM animals, upregulated iNOS gene expression, however down egulated protein expression compared to sham.

BACKGROUND: Gastric cancer has an important epidemiologic impact, and the main curative therapeutic modality for gastric cancer is surgical resection. However, even curative intent therapy can have negative effects on the quality of life (QoL) of these patients, which is undesirable; thus, it is difficult to balance the standardized treatment reported in the literature and treatment response to achieve full patient satisfaction. The purpose of our study was to evaluate the QoL and identify the association of scores on the Functional Assessment of Cancer Therapy-Gastric (FACT-Ga) and Short Form 36 Health Survey version 2 (SF36v2) questionnaires with sociodemographic, clinical and anatomopathological aspects of gastric adenocarcinoma patients undergoing curative surgery. METHODS: This was a cross-sectional study involving 104 patients from three regions of Brazil. Inferential analyses were used to compare (multiple regression and Mann-Whitney or Kruskal-Wallis tests) the relationships between these scores and variables (Spearman's coefficient). RESULTS: In the multiple regression analysis, we found correlations between Helicobacter pylori status and physical well-being (PWB) (P=0.026), between gender and emotional well-being (EWB) (P=0.008), between Lauren's histology and physical functioning (P=0.009), as well as the Short Form 36 Health Survey version 2 (SF-36v2) role-physical (P=0.027), between the tumor site and EWB (P=0.038), between the SF-36v2 mental health and N (the lower the staging, the better the score, P=0.006) and between the SF-36v2 mental health and lymph nodes removed (P=0.029). According to the Mann-Whitney or Kruskal-Wallis test, women had worse FACT-Ga total (P=0.049), PWB (P=0.005), EWB (P=0.007), gastric cancer subscale (GaCS, P=0.011), trial outcome index (TOI, P=0.030) and mental health scores than men (P=0.011). Patients with distal tumors had better scores (FACT-Ga, P=0.018; GaCS, P=0.014; TOI, P=0.020) than patients with proximal tumors. Patients with tumors located in the cardia had better physical functioning than those with proximal tumors (P=0.042). Patients who underwent partial gastrectomy had better FACT-Ga total scores (P=0.011), PWB (P=0.033), GaCS scores (P=0.006) and TOI scores (P=0.008) than those who underwent total gastrectomy. Patients who did not receive adjuvant therapy had worse bodily pain as reported on the SF-36v2 than those who received therapy (P=0.048). According to Spearman's coefficient, a higher lymph node stage corresponded to worse FACT-Ga total (s=-0.200, P=0.034), GaCS (s=-0.206, P=0.037), TOI (s=-0.216; P=0.028) and vitality (s=-0.215, P=0.029) scores. A longer time after treatment corresponded to a better SF-36v2 role-physical domain score (s=0.223; P=0.023). CONCLUSIONS: The type of treatment instituted, postoperative time and sociodemographic and anatomopathological factors influence the QoL.
RESUMO
PURPOSE: To analyze aspects of the biomodulating effect of light in biological tissues, bone cells from surgical explants of the femur of rats were irradiated with low intensity laser. METHODS: Bone cells were cultured and irradiated with LASER light (GaAlAs). Growth, cell viability, mineralized matrix formation, total protein dosage, immunostimulatory properties, cytochemical analysis, gene expression of bone proteins were examined using live cell imaging and cell counting by colorimetric assay. The gene expression of: alkaline phosphatase (ALP), type 1 collagen, osteocalcin and osteopontin through the real-time polymerase chain reaction. RESULTS: At 8 days, the viability of the irradiated culture was 82.3% and 72.4% in non-irradiated cells. At 18 days, the cellular viability (with laser) was 77.42% and 47.62% without laser. At 8 days, the total protein concentration was 21.622 mg / mol in the irradiated group and 16, 604 mg / mol in the non-irradiated group and at 18 days the concentration was 37.25 mg / mol in the irradiated group and 24, 95 mg / mol in the non-irradiated group. CONCLUSION: The laser interfered in the histochemical reaction, cell viability, matrix mineralization, and maintained the cellular expression of proteins.

OBJECTIVE: The objective of our study was to identify which imaging features may be used to differentiate between cirrhosis and chronic hepatosplenic schistosomiasis and to assess image interpretation agreement for MRI findings. MATERIALS AND METHODS: Retrospective review of 27 patients with alcoholic or virus-induced cirrhosis and 24 patients with chronic hepatosplenic schistosomiasis who underwent MRI (1.5 T) of the abdomen was performed. Images were interpreted independently by two radiologists evaluating the following MRI features: hepatic fissure widening, irregularity of hepatic contours, periportal fibrosis, hepatic parenchyma heterogeneity, and splenic siderotic nodules. Left, right, and caudate hepatic lobe measurements were obtained, and the splenic index was measured. The Fisher's exact test, chi-square test, and Student's t test were used to compare both groups, and regression analysis was performed. Observer agreement was measured using kappa and intraclass correlation tests. RESULTS: Periportal fibrosis, heterogeneity of hepatic parenchyma, and splenic siderotic nodules were more frequent in the group with schistosomiasis (p < 0.05), with periportal fibrosis showing the largest difference in presence and distribution (peripheral greater than central). The transverse diameter of the right hepatic lobe, caudate lobe-right lobe ratio, and splenic index were larger in patients with chronic schistosomiasis (p < 0.001). At multiple regression analysis, splenic siderotic nodules, splenic index, and caudate lobe-right lobe ratio were predictive of schistosomiasis. Observer agreement was substantial or almost perfect for almost all variables analyzed (kappa or r = 0.81-1.00). CONCLUSION: The presence of peripheral periportal fibrosis, heterogeneity of hepatic parenchyma, and splenic siderotic nodules, and the splenic index and caudate lobe-right lobe ratio are useful features for differentiating alcoholic or virus-induced cirrhosis from chronic schistosomiasis using MRI.

Background: Healing is an innate biological phenomenon, and carcinogenesis acquired, but with common humoral and cellular elements. Carcinogenesis interferes negatively in healing. Aim: To evaluate the histological changes in laparotomy scars of healthy Balb/c mice and with an Ehrlich tumor in its various forms of presentation. Methods: Fifty-four mice were divided into three groups of 18 animals. First group was the control; the second had Ehrlich tumor with ascites; and the third had the subcutaneous form of this tumor. Seven days after tumor inoculation, all 54 mice were submitted to laparotomy. All of the animals in the experiment were operated on again on 7th day after surgery, with resection of the scar and subsequent euthanasia of the animal. The scars were sent for histological assessment using immunohistochemical techniques to evaluate Cox-2 (cyclooxygenase 2), VEGF (vascular endothelial growth factor) and FGF (fibroblast growth factor). Semi-quantitatively analysis was done in the laparotomy scars and in the abdominal walls far away from the site of the operation. Results: Assessing the weight of the animals, the correct inoculation of the tumor and weight gain in the group with tumoral ascites was observed. The histological studies showed that groups with the tumor showed a statistically significant higher presence of Cox-2 compared to the control. In the Cox-2 analysis of the abdominal wall, the ascites group showed the most significant difference. VEGF did not present any significant differences between the three groups, regardless of the site. The FGF showed a significant increase in animals with the tumor. Conclusion: Histological findings in both laparotomy scar and the abdominal wall showed that with Ehrlich's neoplasia there was an exacerbated inflammatory response, translated by more intense expression of Cox-2 and greater fibroblast proliferation, translated by more intense expression of FGF, that is, it stimulated both the immediate inflammatory reactions, observed with Cox-2 reactions, and late scarring by fibroblasts and FGF.
Racional: A cicatrização é fenômeno biológico inato, e a carcinogênese adquirido, mas com elementos humorais e celulares comuns. A carcinogênese interfere de forma negativa na cicatrização. Objetivo: Avaliar as modificações histológicas nas cicatrizes laparotômicas de camundongos Balb/c sadios como controles, e com a neoplasia de Ehrlich, em suas diferentes formas de apresentação. Métodos: Foram utilizados 54 camundongos, divididos em três grupos de 18 animais cada um. O primeiro era controle; o segundo com a neoplasia de Ehrlich em sua forma ascítica; e o terceiro na forma subcutânea. Sete dias após a inoculação do tumor, todos os 54 camundongos foram submetidos à laparotomia e reoperados no sétimo dia de pós-operatório, com ressecção da cicatriz e posterior eutanásia. As cicatrizes foram encaminhadas para estudo histológico com técnicas imunoistoquímicas para avaliar Cox-2 (ciclo-oxigenase 2), VEGF (fator de crescimento do endotélio vascular) e FGF (fator de crescimento dos fibroblastos) e analisadas de forma semiquantitativana tanto na cicatriz laparotômica como na parede abdominal mais distante do local operado. Resultados: Avaliando o peso, observou-se a correta inoculação do tumor e o aumento de peso no grupo com a neoplasia na modalidade ascítica. Os estudos histológicos mostraram que os grupos com a neoplasia apresentaram maior presença da Cox-2 em relação ao controle, estatisticamente significante. No estudo da Cox-2 da parede abdominal foi o local em que o grupo ascítico apresentou a diferença mais expressiva. O VEGF não apresentou diferenças significantes entre os três grupos, independentemente do local estudado. O FGF teve aumento significante nos animais com neoplasia. Conclusão: Os achados histológicos encontrados tanto na cicatriz das laparotomias quanto na parede abdominal mostraram que com a neoplasia de Ehrlich houve resposta inflamatória exacerbada, traduzida por expressão mais intensa da Cox-2 e maior proliferação fibroblástica, traduzida por expressão mais intensa do FGF, ou seja, estimulou tanto as reações inflamatórias imediatas, observadas nas reações da Cox-2, como nas cicatriciais tardias com os fibroblastos e o FGF.

INTRODUCTION: The nonoperative management of traumatic spleen injuries is the modality of choice in patients with blunt abdominal trauma and hemodynamic stability. However, there are still questions about the treatment indication in some groups of patients, as well as its follow-up. AIM: Update knowledge about the spleen injury. METHOD: Was performed review of the literature on the nonoperative management of blunt injuries of the spleen in databases: Cochrane Library, Medline and SciELO. Were evaluated articles in English and Portuguese, between 1955 and 2014, using the headings "splenic injury, nonoperative management and blunt abdominal trauma". RESULTS: Were selected 35 articles. Most of them were recommendation grade B and C. CONCLUSION: The spleen traumatic injuries are frequent and its nonoperative management is a worldwide trend. The available literature does not explain all aspects on treatment. The authors developed a systematization of care based on the best available scientific evidence to better treat this condition.

SUMMARY OBJECTIVE: To analyze abdominal drain on the first postoperative day and evaluate its predictive nature for the diagnosis of Pancreatic Fistula exclusion, seeking to establish a cutoff point from which lower values demonstrate safety in excluding the possibility of this complication. METHODS: From August 2017 to June 2020, data from 48 patients undergoing pancreatic resection were collected and analyzed from a prospective cohort. The patients were divided into two groups, one group consisting of patients who did not develop PF (Group A), and the other composed of patients who developed PF (Group B). The receiver operation characteristic curve was constructed, and cutoff points were evaluated by calculating sensitivity and specificity. RESULTS: Group A brought 30 patients together (62.5%) and Group B brought 18 patients together (37.5%). The 444 U/L value was the most satisfactory cutoff point for the receiver operation characteristic curve (CI 0.690-0.941), with a sensitivity of 94.4% and a specificity of 60%, thus being able to select 18 of 30 patients who did not succumb to PF. CONCLUSIONS: Abdominal drain on the first postoperative day can be used as a predictive factor in the diagnosis of PF exclusion (CI 0.690-0.941), with the value of 444 U/L being the best performance cutoff point.

Background: Surgical strategy to increase the number of liver transplants in the pediatric population is the ex-situ liver transection (reduction or split). However, it is associated with complications such as hemorrhage and leaks. The human fibrinogen and thrombin sponge is useful for improving hemostasis in liver surgery. Aim: Compare pediatric liver transplants with ex-situ liver transection (reduction or split) with or without the human fibrinogen and thrombin sponge. Methods: Was performed a prospective analysis of 21 patients submitted to liver transplantation with ex-situ liver transection with the application of the human fibrinogen and thrombin sponge in the wound area (group A) and retrospective analysis of 59 patients without the sponge (group B). Results: The characteristics of recipients and donors were similar. There were fewer reoperations due to bleeding in the wound area in group A (14.2%) compared to group B (41.7%, p=0.029). There was no difference in relation to the biliary leak (group A: 17.6%, group B: 5.1%, p=0.14). Conclusion: There was a lower number of reoperations due to bleeding of the wound area of ââthe hepatic graft when the human fibrinogen and thrombin sponge were used.
Racional: Estratégia cirúrgica para aumentar o número de transplantes hepáticos na população pediátrica é a transecção hepática ex-situ (redução ou split). No entanto, ela está associada com complicações, tais como hemorragia e fístulas. A esponja de fibrinogênio e trombina humana é útil para melhorar a hemostasia nas operações hepáticas. Objetivo: Comparar transplantes hepáticos pediátricos com transecção hepática ex-situ (redução ou split) com ou sem a esponja de fibrinogênio e trombina humana. Métodos: Foi realizada análise prospectiva de 21 pacientes submetidos ao transplante de fígado com transecção hepática ex-situ com a aplicação da esponja de fibrinogênio e trombina humana na área cruenta (grupo A) e análise retrospectiva de 59 pacientes sem a esponja (grupo B). Resultados: As características dos receptores e doadores eram semelhantes. Observou-se menor número de reoperações devido à hemorragia na área da cruenta no grupo A (14,2%) em comparação com o grupo B (41,7%, p=0,029). Não houve diferença em relação à fístula biliar (grupo A: 17,6%, grupo B: 5,1%, p=0,14). Conclusão: Houve menor número de reoperações por sangramento da área cruenta do enxerto hepático quando a esponja de fibrinogênio e trombina humana foi utilizada.
