Abstract
Background: This study aimed to explore a low-cost solution for virtual surgical planning/3D printed surgical guides in a training hospital, assessing the impact on intraoperative time and bleeding. Material and Methods: We included a total of 13 patients. 8 who underwent maxillofacial reconstruction surgery with fibula-free flap utilizing virtual surgical planning/3D printed guides (VP/SG), and 5 using conventional surgery (CS) from 2017 to 2020. The surgical time, bleeding, length of hospital stay, and comorbidities were collected and compared in two groups. We recorded the average cost for the complete surgical planning and 3D printed guides. We applied a qualitative survey to the surgeons involved in the surgical procedures. Results The mean surgical time in the VP/SG group was 8.16 ± 2.7, compared to the CS group 12.5 ± 3.8, showing a 4.34 hours difference with statistical significance (p = 0.033). Patients from the CS group had a higher bleeding volume of 921 ± 467.6 mL VS 760 ± 633.8 mL in the VP/SG group. The average cost for the complete surgical planning and 3D printed guides was 914.44 ± 46.39 USD. All the surgeons who answered the survey preferred to perform the procedure utilizing the virtual planning/3D printed guides. Conclusions Virtual planning and 3D printed surgical guides have the potential to reduce operation time in maxillofacial reconstruction.

Abstract
BACKGROUND: Due to the reported low incidence of gastrointestinal TB, there is a lack of data related to the prognosis, risk factors and frequency of resistant TB in this subgroup of patients.OBJECTIVE: To report the clinical presentation, diagnostic methods, treatment and outcomes in gastrointestinal TB.METHODS: We prospectively studied the demographic, clinical, and paraclinical data of all consecutive gastrointestinal TB inpatients over an 8-year period.RESULTS: We identified gastrointestinal TB in 28 (3.5%) out of 799 inpatients with TB infection. Seven patients (25%) were HIV-positive. Overall mortality was 35.7%, with the combined variable of haemoglobin <12 g/dL and albumin <2.8 g/dL being independently associated with mortality (OR 25.7, 95% CI 1.405-471.1, P = 0.029). No difference in the need for surgery (28.6% vs. 47.6%, P = 0.662), occurrence of septic shock (14.3 vs. 23.8%, P = 1.00) or mortality (14.3% vs. 42.9%, P = 0.364) was found between HIV and non-HIV patients.CONCLUSION: Gastrointestinal TB was rare among TB patients in Hospital Universitario "Dr José E. González" (3.5%), but had a high mortality rate (35.7%). Clinical evolution, drug susceptibility patterns and outcomes were similar in HIV and non-HIV patients. In both groups, the combined haemoglobin and albumin variable on admission was clearly associated with mortality.

Abstract
OBJECTIVES To explore a method to create affordable anatomical models of the biliary tree that are adequate for training laparoscopic cholecystectomy with an in-house built simulator. METHODS We used a fused deposition modeling 3D printer to create molds of Acrylonitrile Butadiene Styrene (ABS) from Digital Imaging and Communication on Medicine (DICOM) images, and the molds were filled with silicone rubber. Thirteen surgeons with 4-5-year experience in the procedure evaluated the molds using a low-cost in-house built simulator utilizing a 5-point Likert-type scale. RESULTS Molds produced through this method had a consistent anatomical appearance and overall realism that evaluators agreed or definitely agreed (4.5/5). Evaluators agreed on recommending the mold for resident surgical training. CONCLUSIONS 3D-printed molds created through this method can be applied to create affordable high-quality educational anatomical models of the biliary tree for training laparoscopic cholecystectomy.

Abstract
PURPOSE To explore the potential of radiomics texture features as potential biomarkers to enable detection of the presence of BRAF mutation and prediction of 5-year overall survival (OS) in stage IV colorectal cancer (CRC). MATERIALS AND METHODS In this retrospective study, a total of 145 patients (mean age, 61 years ± 14 [standard deviation {SD}]; 68 female patients and 77 male patients) with stage IV CRC who underwent molecular profiling and pretreatment contrast material-enhanced CT scans between 2004 and 2018 were included. Tumor radiomics texture features, including the mean, the SD, the mean value of positive pixels (MPP), skewness, kurtosis, and entropy, were extracted from regions of interest on CT images after applying three Laplacian-of-Gaussian filters known as spatial scaling factors (SSFs) (SSF = 2, fine; SSF = 4, medium; SSF = 6, coarse) by using specialized software; values of these parameters were also obtained without filtration (SSF = 0). The Wilcoxon rank sum test was used to assess differences between mutated versus wild-type BRAF tumors. Associations between radiomics texture features and 5-year OS were determined by using Kaplan-Meier estimators using the log-rank test and multivariate Cox proportional-hazards regression analysis. RESULTS The SDs and MPPs of radiomic texture features were significantly lower in BRAF mutant tumors than in wild-type BRAF tumors at SSFs of 0, 4, and 6 (P = .006, P = .007, and P = .005, respectively). Patients with skewness less than or equal to -0.75 at an SSF of 0 and a mean of greater than or equal to 17.76 at an SSF of 2 showed better 5-year OS (hazard ratio [HR], 0.53 [95% confidence interval {CI}: 0.29, 0.94]; HR, 0.40 [95% CI: 0.22, 0.71]; log-rank P = .025 and P = .002, respectively). Tumor location (right colon vs left colon vs rectum) had no significant impact on the clinical outcome (log-rank P = .53). CONCLUSION Radiomics texture features can serve as potential biomarkers for determining BRAF mutation status and as predictors of 5-year OS in patients with advanced-stage CRC.Keywords: Abdomen/GI, CT, Comparative Studies, Large BowelSupplemental material is available for this article.© RSNA, 2020.

Abstract
BACKGROUND Pancreatic cancer induces parenchymal atrophy and duct dilation. The aim of this study was to evaluate whether these radiologic modifications are associated with outcomes. METHODS Upfront pancreaticoduodenectomy patients with available preoperative contrast enhanced CT scan imaging were retrospectively analyzed. Thickness of the pancreas, size of the main pancreatic duct (MPD), and distance of the tumor from the ampulla were assessed. A training cohort was selected, including short- (3-12 months following surgery) and long-term (≥ 36 months) survivors. Identified survival determinants were validated in the overall cohort. RESULTS Two-hundred-sixteen patients were analyzed. In the training cohort (N = 118), 68 patients (57.6%) were in the short-term and 50 (42.4%) in the long-term survival group. The short-term survival group had significantly higher CA 19-9 levels (p = 0.027), larger tumors (32.6 ± 12.1 mm vs. 26.5 ± 11.6 mm, p = 0.007), poorer differentiation (p = 0.003), higher rate of R < 1 mm resections (54% vs. 32%, p = 0.008), and reduced receipt of adjuvant chemotherapy (p = 0.020). The MPD-to-pancreatic thickness ratio was significantly lower in the short-term survivors (3.6 ± 6.2 vs. 8.2 ± 12.0, p = 0.016). In the entire cohort, an MPD-to-pancreatic thickness ratio ≥ 3.5 was associated with improved OS [median 33.0 months IQR (19.7-48.1) versus 17 months IQR (14.8-19.2), p = 0.004], and confirmed by a Cox-proportional hazards model independently associated with OS (HR = 0.58; p = 0.009), together with tumor size (HR = 1.02; p =0.012), R1/R2 status (HR = 1.53; p = 0.029), and receipt of adjuvant treatment (HR = 0.61; p = 0.021). CONCLUSIONS High MPD-to-pancreatic thickness ratio was associated with improved long-term survival in pancreaticoduodenectomy for cancer. Whether these features are related to tumor chronicity, indolent biology, or local growth over metastasis remains to be determined.
