title: Surgical treatment in hepatic trauma: factors associated with hospitalization time

description: ABSTRACT Objective: the aim of this study was to identify associated factors with the increased length of hospital stay for patients undergoing surgical treatment for liver trauma, and predictors of mortality as well as the epidemiology of this trauma. Methods: retrospective study of 191 patients admitted to the Cajuru University Hospital, a reference in the treatment of multiple trauma patients, between 2010 and 2017, with epidemiological, clinicopathological and therapeutic variables analyzed using the STATA version 15.0 program. Results: most of the included patients were men with a mean age of 29 years. Firearm injury represents the most common trauma mechanism. The right hepatic lobe was injured in 51.2% of the cases, and hepatorraphy was the most commonly used surgical correction. The length of hospital stay was an average of 11 (0-78) days and the length of stay in the intensive care unit was 5 (0-52) days. Predictors for longer hospital stay were the mechanisms of trauma, hemodynamic instability at admission, number of associated injuries, degree of liver damage and affected lobe, used surgical technique, presence of complications, need for reoperation and other surgical procedures. Mortality rate was 22.7%. Conclusions: the study corroborated the epidemiology reported by the literature. Greater severity of liver trauma and associated injuries characterize patients undergoing surgical treatment, who have increased hospital stay due to the penetrating trauma, hemodynamic instability, hepatic packaging, complications and reoperations.

title: Safe surgery checklist: evaluation in a neotropical region

description: ABSTRACT Objective: assess patient responses and associated factors of items on a safe surgery checklist, and identify use before and after protocol implementation from the records. Methods: a cohort study conducted from 2014 to 2016 with 397 individuals in stage I and 257 in stage II, 12 months after implementation, totaling 654 patients. Data were obtained in structured interviews. In parallel, 450 checklist assessments were performed in medical records from public health institutions in the Southwest II Health Region of Goiás state, Brazil. Results: six items from the checklist were evaluated and all of these exhibited differences (p &lt; 0.000). Of the medical records analyzed, 69.9% contained the checklist in stage I and 96.5% in stage II, with better data completeness. In stage II, after training, the checklist was associated with surgery (OR; 1.38; IC95%: 1.25-1.51; p &lt; 0.000), medium-sized hospital (OR; 1.11; CI95%; 1.0-1.17; p &lt; 0.001), male gender (OR; 1.07; CI95%; 1.0-1.14; p &lt; 0.010), type of surgery (OR; 1.7; CI95%: 1.07-1.14; p &lt; 0.014) and antibiotic prophylaxis 30 to 60 min after incision (OR; 1.10; CI95%: 1.04-1.17; p &lt; 0.000) and 30 to 60 min after surgery (OR; 1.23; CI95%: 1.04-1.45; p = 0.015). Conclusions: the implementation strategy of the safe surgery checklist in small and medium-sized healthcare institutions was relevant and associated with better responses based on patient, data availability and completeness of the data.

title: Comparison of results on the use of extended criteria liver doners for transplants in Espírito Santo

description: ABSTRACT Introduction: liver Transplantation is currently the treatment of choice for several terminal liver diseases. Despite the increase in performed transplants, the waiting lists continue to increase. In order to expand the supply of organs, transplantation teams have started to use previously rejected livers for transplants because of an increased risk of unfavorable outcomes. Objective: to evaluate the use of livers of expanded criterion donators. Methods: retrospective study of medical records. The livers were classified as normal or expanded criteria. The groups were divided in low and high MELD. A multivariate analysis was performed through logistic regression. Results: there was no statistical difference regarding early, late and global mortality between the groups. Decreased survival was observed in patients with high MELD (higher or equal to 20) when they received grafts from expanded criterion donators. The association between the occurrence of cardiorespiratory arrest and presence of elevated total bilirubin in donators was associated with higher mortality rates in expanded criterion livers. Conclusion: the overall results are similar, but expanded criteria liver donators was associated with higher mortality in patients with high MELD.

title: Preoperative computed tomography-guided localization of lung nodules with needle placement: a series of cases

description: ABSTRACT Objective: to report the preoperative localization of pulmonary nodules with the placement of a guidewire oriented by Computed Tomography. Methods: the nodules were marked using a needle in the shape of a hook or another in the shape of a Q, guided by tomography. The choice of the location for the marking was the shortest distance from the chest wall to the nodule. The marking procedure was performed under local anesthesia and a tomographic control was obtained immediately at the end. Patients were referred to the operating room. Surgical resection occurred less than two hours after the needle placement. Results: between February 2017 and October 2019, 22 patients aged 43 to 82 years (mean 62.1) were included. The nodules had diameters that varied from 4 to 30 mm and the distance between the nodules and the pleural surface varied from 2 to 43 mm. The location and resection of the nodules were successfully performed in all cases. The guidewire was displaced in five cases. Five patients presented pneumothorax, with the space between the visceral and parietal pleura varying from 2 to 19 mm. In nine patients, an intraparenchymal hematoma of 6 to 35 mm in length was observed without signs, symptoms, or hemodynamic and ventilatory repercussions. The histopathological study was conclusive in all patients. Conclusions: the localization of pulmonary nodules through guidewires proved to be safe, reliable, and feasible in this series of cases. There was no need for surgical intervention to treat complications.

title: Robotic thoracic surgery for inflammatory and infectious lung disease: initial experience in Brazil

description: ABSTRACT Objective: in Latin America, especially Brazil, the use of a robotic platform for thoracic surgery is gradually increasing in recent years. However, despite tuberculosis and inflammatory pulmonary diseases are endemic in our country, there is a lack of studies describing the results of robotic surgical treatment of bronchiectasis. This study aims to evaluate the surgical outcomes of robotic surgery for inflammatory and infective diseases by determining the extent of resection, postoperative complications, operative time, and length of hospital stay. Methods: retrospective study from a database involving patients diagnosed with bronchiectasis and undergoing robotic thoracic surgery at three hospitals in Brazil between January of 2017 and January of 2020. Results: a total of 7 patients were included. The mean age was 47 + 18.3 years (range, 18-70 years). Most patients had non-cystic fibrosis bronchiectasis (n=5), followed by tuberculosis bronchiectasis (n=1) and lung abscess (n=1). The performed surgeries were lobectomy (n=3), anatomic segmentectomy (n=3), and bilobectomy (n=1). The median console time was 147 minutes (range 61-288 min.) and there was no need for conversion to open thoracotomy. There were no major complications. Postoperative complications occurred in one patient and it was a case of constipation with the need for an intestinal lavage. The median for chest tube time and hospital stay, in days, was 1 (range, 1-6 days) and 5 (range, 2-14 days) respectively. Conclusions: robotic thoracic surgery for inflammatory and infective diseases is a feasible and safe procedure, with a low risk of complications and morbidity.

title: Laparoscopic cholecystectomy performed by general surgery residents. Is it safe? How much does it cost?

description: ABSTRACT Objective: to evaluate the effectiveness and safety of laparoscopic cholecystectomies performed by residents of the first and second-year of a general surgery residency program. We studied the primary total cost of treatment and complication rates as primary outcomes, comparing the groups operated by senior and resident surgeons. Methods: this was a retrospective cohort study of patients who underwent laparoscopic cholecystectomy performed in a training hospital of large surgical volume in Brazil, in the period between June 1, 2018 and May 31, 2019. The study population comprised patients who underwent elective cholecystectomy due to uncomplicated chronic calculous cholecystitis or to the presence of gallbladder polyps with surgical indication. We divided the cases into three groups, based on the graduation of the main surgeon at the time of the procedure: first-year residents (R1), second-year residents (R2), and trained general surgeons (GS). Results: during the study period, 1,052 laparoscopic cholecystectomies were performed, of which 1,035 procedures met the inclusion criteria, with 78 (7.5%) patients operated on with the participation of first-year residents (R1), 500 (48.3%) patients with the participation of second-year residents (R2), and 457 (44.2%) with the participation of senior surgeons only. There was no difference in conversion rates, complications, and reporting of adverse events between groups. We observed a significant difference regarding hospitalization costs (p = 0.003), with a higher mean for the patients operated with the participation of R1, of US$ 2,671.13, versus US$ 2,414.60 and US$ 2,396.24 for the procedures performed by senior surgeons and R2, respectively. Conclusions: laparoscopic cholecystectomy with the participation of residents is safe, even in their first years of training. There is an additional cost of about 10% in the treatment of patient operated with the participation of first-year residents. There was no significant difference in the cost of the group operated by second-year residents.

title: Complications using tissue expanders in burn sequelae treatment at a reference university hospital: a retrospective study

description: ABSTRACT Background: tissue expanders have high relevance in plastic surgery and among indications it is worth mentioning their use in the treatment of burn reconstruction. Although it shows good results, its use requires special care because some complications can interrupt the reconstruction process. The objective of this study was to report the experience of the Clinics Hospital (University of Sao Paulo) with the use of tissue expanders to treat burn sequelae, establishing the incidence of complications, and identifying risk factors for their occurrence. Methods: a retrospective, observational, and analytical study, evaluating the use of expanders in burns sequelae treatment from 2009 to 2018. Results: 245 expanders were placed in 84 patients, 215 were female, with a mean age of 19.96 years, being 40% in the trunk and 20% in the scalp, with a predominance of rectangular shape in 76.7% of cases. Complications were classified as major and minor.Complications occurred in 17.95% of cases, and extrusion and infection were the most common. There was a higher incidence of complications in expanders used in the upper and lower limbs as well as in those who did not undergo concomitant expansion (p &lt;0.05), with an even higher chance of major complications in patients submitted to additional expansion. From 2009 to 2018, we observed a decrease in the incidence of complications. Conclusion: the complication rate (17.95%) is similar to other studies of the literature, there was a higher rate of complication with expanders placed in the limbs and a higher rate of major complications when additional expansion was done.
