RESUMO
PURPOSE: Intraoperative bleeding during hepatectomy is primarily controlled through anaesthesiological interventions or surgical techniques such as Pringle maneuver (PM). Infrahepatic IVC clamping (IIVCC) is an alternative surgical technique to reduce central venous pressure and prevent retrograde hepatic venous bleeding. The aim of the meta-analysis was to compare IIVCC+PM with PM alone in terms of intraoperative outcomes and perioperative complications. METHODS: Medline, Cochrane Library, Scopus, Web of Science, and EMBASE were searched for comparative studies till 16.04.2024, resulting in 679 articles, of which eight studies met inclusion criteria. Data on patient demographics, surgical technique, and perioperative outcomes was assessed. Cochrane Risk of Bias 2.0 (RoB 2.0) Tool and Newcastle-Ottawa Scale (NOS) were used for risk of bias assessment. RESULTS: Two randomized controlled trials, one prospective, and five retrospective cohort studies with 358 patients in IIVCC+PM and 397 patients in PM alone group were included. IIVCC+PM resulted in significantly greater CVP reduction, less intraoperative blood loss (MD (95% CI) = - 233.03 (- 360.48 to - 105.58), P < 0.001), and less intraoperative blood transfusion (OR (95% CI) = 0.38 (0.25 to 0.57), P < 0.001) compared to PM alone. The two groups had comparable total operative time, transection time and total intraoperative fluid infusion. Patients undergoing IIVCC+PM had significantly shorter length of stay (MD (95% CI) = - 0.63 days (- 1.21 to - 0.05 days), P = 0.03) and overall complication rates (OR (95% CI) = 0.63 (0.43-0.92), P = 0.02) compared to PM alone group. CONCLUSION: The utilization of IIVCC along with PM during liver resection may be beneficial in reducing intraoperative bleeding and blood transfusion without adversely influencing operative times or perioperative outcomes compared to PM alone.

BACKGROUND: Despite the increased use of minimally invasive approaches for pancreatoduodenectomy (PD), the association between surgical approach and venous thromboembolism (VTE) risk is still unknown. This study aims to compare VTE rates following open (OPD) and minimally invasive pancreatoduodenectomy (MIPD). METHOD: MEDLINE, Web of Sciences and EMBASE databases were searched to identify eligible studies. Studies were considered suitable if the incidence of postoperative VTE in open and minimally invasive (laparoscopic or robotic) pancreatic surgery was reported. The review was conducted following the PRISMA guidelines. RESULTS: Five studies including 12 984 patients met the inclusion criteria and were considered for meta-analysis. A total of 11 060 patients underwent OPD and 1924 MIPD. Overall, patients who underwent OPD had a lower rate of VTE compared to MIPD (3.6 % vs 4.6 %, OR (95 % CI) = 0.66 (0.52-0.85), p < 0.001). Subgroup analysis showed similar results for pulmonary embolism (PE) (1.1 % in OPD vs 1.9 % in MIPD, OR (95 % CI) = 0.54 (0.36-0.80), p 0.002) and deep venous thrombosis (DVT) (1.3 % in OPD vs 3.1 % in MIPD, OR (95 % CI) = 0.48 (0.29-0.79), p 0.004). CONCLUSION: Patients who undergo minimally invasive pancreatoduodenectomy have a higher incidence of postoperative VTE when compared to open pancreatoduodenectomy.

Background: Evidence suggests that patients with Hashimoto thyroiditis (HT) are at significantly higher risk of developing papillary thyroid cancer (PTC). However, the course of PTC in patients with both diseases concomitantly has been found to be more indolent than conventional PTC. Additionally, it has been well proven that BRAF mutation results in an aggressive course of PTC. The aims of this meta-analysis were to identify prevalence of BRAF mutation and its impact on clinicopathological features in patients with concomitant PTC-HT. Methods: Medline, Cochrane Library, Scopus, and Web of Science were searched until 16.09.2022, resulting in 227 articles, of which nine studies were included. Summary estimates, comparing patients with (A) BRAF (+) PTC-HT versus BRAF (+) PTC, and (B) BRAF (+) PTC-HT versus BRAF (-) PTC-HT, were generated with Review Manager 5.0. Results: In total, 6395 patients were included in this review. PTC-HT patients had significantly less BRAF mutation than PTC patients (Odds Ratio (OR) (95% Confidence Interval (CI))=0.45 (0.35-0.58), P<0.001). BRAF (+) PTC-HT patients were significantly more likely to have multifocal lesions (OR (95% CI)=1.22 (1.04-1.44), P=0.01) but less likely to have lymph node metastasis (OR (95% CI)=0.65 (0.46-0.91), P=0.01) and extrathyroidal extension (OR (95% CI)=0.55 (0.32-0.96), P=0.03) compared to BRAF (+) PTC patients. BRAF (+) PTC-HT patients were more likely to have multifocal lesions (OR (95% CI)=0.71 (0.53-0.95), P=0.02), lymph node metastasis (OR (95% CI)=0.59 (0.44-0.78), P<0.001) and extrathyroidal extension (OR (95% CI)=0.72 (0.56-0.92), P=0.01) compared to BRAF (-) PTC-HT patients. Conclusion: This meta-analysis highlights that the lower prevalence of BRAF mutation in patients with PTC-HT than conventional PTC may explain the indolent clinicopathological course in this cohort.

INTRODUCTION AND AIM: Para-aortic lymph node metastasis associated with colorectal cancer is a very rare occurrence, but at the same time an important predictor of survival. Despite its importance, there is still no gold standard management strategy, particularly for lymph nodes detected during follow-up, after resection of the primary tumour. Therefore, this review was undertaken to examine the evidence available on the surgical and non-surgical management of metachronous para-aortic lymph node metastasis (m-PALNM) in colorectal cancer treatment. METHODS: This is a systematic review using the patient, intervention, comparison, outcome and study strategy. The literature search was undertaken using Cochrane, MEDLINE, EMBASE and PubMed databases with the following MeSH terms: lymph node excision, para-aortic lymph node, metastasis, metachronous and colorectal neoplasms. RESULTS: Five original papers met the study criteria including 188 patients in total (55.3% male, 44.7% female). Surgical resection of the m-PALND was the management of choice in 64% of patients. Reporting styles on survival outcomes were heterogeneous. However, patients undergoing surgical management for m-PALNM had longer disease-free survival and overall survival rates. CONCLUSION: There is significant paucity in the evidence available on the management of m-PALNM. However, the evidence reported by this review suggests that surgical management should be considered whenever possible, with the aim of prolonging survival. Future randomised trials are needed in order to provide further high-level evidence on m-PALNM management.

INTRODUCTION: Antineutrophil cytoplasmic antibody-associated vasculitides (AAV) are a group of autoimmune diseases characterized by inflammation of small blood vessels. Smoking is a potential trigger for such diseases, however, its link with AAV remains controversial. OBJECTIVES: The aim of this study was to analyze the link between AAV and smoking based on clinical characteristics, disease activity, and mortality. METHODS: This retrospective study included 223 AAV patients. Their smoking status was assessed at diagnosis and they were classified as ever smokers (ESs), including current or past smokers, and never smokers (NSs). Information regarding clinical presentation, the disease activity, immunosuppressive therapy, and survival was collected. RESULTS: The ESs had similar organ involvement to the NSs, except for significantly greater frequency of renal replacement therapy (31% vs 14%; P = 0.003). Median (interquartile range [IQR]) time from symptom onset to diagnosis was significantly shorter in the ESs than the NSs (4 [2-9.5] vs 6 [3-13] months; P = 0.03), with significantly higher mean (SD) value of the Birmingham Vasculitis Activity Score version 3 (19.5 [7.93] vs 17.25 [8.05]; P = 0.04). The ESs were more likely to receive cyclophosphamide therapy (P = 0.03), and had significantly higher morality than the NSs (hazard ratio, 2.89; 95% CI, 1.47-5.72; P = 0.002). There were no significant differences between the current and past smokers. The multivariable Cox proportional regression analysis found ever smoking and male sex to be independent predictors of mortality in AAV patients. CONCLUSION: Ever smoking is associated with increased AAV activity and more frequent renal replacement therapy and immunosuppressive treatment, resulting in a poorer survival prognosis in AAV patients. Future multicenter studies are required to further characterize the clinical, biological, and prognostic impact of smoking on AAV.

Medicine is a rapidly-evolving discipline, with progress picking up pace with each passing decade. This constant evolution results in the introduction of new tools and methods, which in turn occasionally leads to paradigm shifts across the affected medical fields. The following review attempts to showcase how 3D printing has begun to reshape and improve processes across various medical specialties and where it has the potential to make a significant impact. The current state-of-the-art, as well as real-life clinical applications of 3D printing, are reflected in the perspectives of specialists practicing in the selected disciplines, with a focus on pre-procedural planning, simulation (rehearsal) of non-routine procedures, and on medical education and training. A review of the latest multidisciplinary literature on the subject offers a general summary of the advances enabled by 3D printing. Numerous advantages and applications were found, such as gaining better insight into patient-specific anatomy, better pre-operative planning, mock simulated surgeries, simulation-based training and education, development of surgical guides and other tools, patient-specific implants, bioprinted organs or structures, and counseling of patients. It was evident that pre-procedural planning and rehearsing of unusual or difficult procedures and training of medical professionals in these procedures are extremely useful and transformative.

BACKGROUND: The use of proton pump inhibitors (PPI) is common worldwide, with reports suggesting that they may be overused. Several studies have found that PPI may affect colorectal cancer (CRC) risk. AIM: To summarize current knowledge on the relationship between PPI and CRC from basic research, epidemiological and clinical studies. METHODS: This systematic review was based on the patients, interventions, comparisons, outcome models and performed according to PRISMA guidelines. MEDLINE, EMBASE, Scopus, and Web of Science databases were searched from inception until May 17, 2021. The initial search returned 2591 articles, of which, 28 studies met the inclusion criteria for this review. The studies were categorized as basic research studies (n = 12), epidemiological studies (n = 11), and CRC treatment studies (n = 5). The quality of the included studies was assessed using the Newcastle-Ottawa Scale or Cochrane Risk of Bias 2.0 tool depending on the study design. RESULTS: Data from basic research indicates that PPI do not stimulate CRC development via the trophic effect of gastrin but instead may paradoxically inhibit it. These studies also suggest that PPI may have properties beneficial for CRC treatment. PPI appear to have anti-tumor properties (omeprazole, pantoprazole), and are potential T lymphokine-activated killer cell-originated protein kinase inhibitors (pantoprazole, ilaprazole), and chemosensitizing agents (pantoprazole). However, these mechanisms have not been confirmed in human trials. Current epidemiological studies suggest that there is no causal association between PPI use and increased CRC risk. Treatment studies show that concomitant PPI and capecitabine use may reduce the efficacy of chemotherapy resulting in poorer oncological outcomes, while also suggesting that pantoprazole may have a chemosensitizing effect with the fluorouracil, leucovorin, oxaliplatin (FOLFOX) regimen. CONCLUSION: An unexpected inhibitory effect of PPI on CRC carcinogenesis by way of several potential mechanisms is noted. This review identifies that different PPI agents may have differential effects on CRC treatment, with practical implications. Prospective studies are warranted to delineate this relationship and assess the role of individual PPI agents.

Recurrent laryngeal nerve injury is an important complication following thyroid and parathyroid surgery. Recently, Transcutaneous laryngeal ultrasound (TLUSG) has emerged as a non-invasive alternative to laryngoscopic examination for vocal cord (VC) assessment. The aim of the systematic review and meta-analysis was to determine its diagnostic accuracy in reference to laryngoscopy. It was conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. MEDLINE, Scopus, Cochrane library and Web of Science databases were searched to identify relevant articles. Sixteen studies were included in the review. Pooled diagnostic accuracy was calculated based on weighted arithmetic mean and plotting forest plot. The pooled visualization rate was 86.28% and 94.13% preoperatively and postoperatively, respectively. The respective pooled sensitivity and specificity was 78.48% and 98.28%, and 83.96% (CI 95%: 77.24-88.50%) and 96.15% (CI 95%: 95.24-96.88%). The diagnostic accuracy improved if transverse and lateral approaches, and valsalva maneuver were utilized. Male gender and older age were the most crucial risk factors for VC non-visualization. TLUSG is an efficacious screening tool for vocal cord palsy due to its high sensitivity. It is likely to prevent unnecessary laryngoscopic examination in around 80% of patients, with the potential for becoming a gold standard for specific (female/young) patient cohort through assimilative modifications use, increasing expertise and development of objective measurements in the future.
RESUMO
OBJECTIVES: Fibromyalgia (FM) is a chronic widespread pain syndrome, known to be associated with several other symptoms. Chronic stress is suspected to be a contributing factor in the pathogenesis of FM. It is known that medical students are under a constant state of stress originating from personal and social expectations. The aim of the study was to assess the prevalence of FM in this population and identify lifestyle parameters influencing FM severity. MATERIAL AND METHODS: An online survey of first- and final-year medical students was conducted using the ACR modified 2016 criteria and FANTASTIC checklist. The survey acquired demographic information such as age, gender, year, and division of studies. A subgroup analysis based on gender, year of studies, and division of studies was performed. RESULTS: 439 medical students (71% females) completed the survey. The overall prevalence of FM in our cohort was 10.48%. The ratio of females to males was 3 : 1. A significant negative correlation between better quality of lifestyle and worse FM severity was observed in all subgroups. The "insight", "sleep and stress", "behavior" and "career" domains of lifestyle were found to have a significant negative correlation with FM severity on univariate analysis. CONCLUSIONS: The prevalence of FM in medical students seems to be considerably higher than in the general population. Chronic stress levels, sleep problems, social support, and behavior seem to be the major factors influencing FM severity in this population. Our findings suggest that medical students must be considered a "high-risk" group for FM, and hence must be identified, educated, and managed accordingly. It is, therefore, important for medical universities to implement programs educating students about FM, the importance of a healthy lifestyle, and stress coping strategies, while also making systemic changes to curb stressors in medical training.
RESUMO
INTRODUCTION: As a result of the COVID-19 pandemic, the health care systems around the world have been overburdened resulting in significant reduction of planned surgical procedures such as bariatric surgeries. The primary aim of this study is to assess the influence of the COVID-19 national lockdown in Poland on the short-term outcomes and intraoperative course of bariatric patients in a high volume IFSO certified bariatric center. MATERIAL & METHODS: This is a retrospective analysis of 158 bariatric surgery patients, who underwent bariatric procedures either prior to or after the first national lockdown in Poland. The patients were categorized as pre-lockdown group and the post-lockdown group, each comprising of 79 patients. RESULTS: The post-lockdown group had significantly lower operative weight (105.76 vs 114.25, p = 0.012) and BMI (36.99 vs 39.93, p = 0.005) compared to pre-lockdown group. The primary length of stay was significantly longer in the post-lockdown group (3.04 vs 2.44, p = 0.001). The post-lockdown group had significantly lower mean CCI score (1.90 vs 6.67, p = 0.046) and less short-term readmissions post-discharge (0 vs 8.86, p = 0.007) than pre-lockdown group. CONCLUSION: The post-lockdown group was found to have lower body weight and BMI on the day of the operation than those operated prior to the lockdown. These findings are conflicting to previous research assessing weight changes during lockdowns. Since the qualification criteria and order of operations were similar and pre-defined for both groups, possible explanations for these findings are higher patient motivation due to COVID-19 fears and longer preparation period due to elective surgery postponement. We encourage bariatric centers globally to assess the effect of national lockdowns on the patient profiles as well as the psychological and behavioral impact on the bariatric cohort.

BACKGROUND: Short-course radiotherapy with consolidation chemotherapy (SCRT-CCT) has emerged as a promising alternative to the long course chemoradiotherapy (LCRT) regimen in locally advanced rectal cancer management. The systematic review and meta-analysis is aimed at summarizing current evidence on SCRT-CCT and comparing it to LCRT. MATERIAL AND METHODS: Electronic databases of MEDLINE, Web of Science, and Cochrane library were searched using a predefined search strategy returning 3314 articles. This review included 11 studies (6 randomized trials and 5 non-randomized studies) on SCRT-CCT regimen based on seven different cohorts. Weighted arithmetic means and forest plots were generated to determine summary estimates. RESULTS: The probability of achieving pathological complete response (pCR) was higher with SCRT-CCT compared to LCRT (risk ratio [RR] = 1.75, 95% confidence interval [CI]: 1.41-2.19). No statistically significant difference in 3-year overall survival (OS) was observed between the two groups (RR= 1.06, 95% CI: 0.98-1.14). The weighted arithmetic mean of 3-year OS and pCR was 83.6% versus 80.9%, and 24.5% versus 13.6% for SCRT-CCT and LCRT, respectively. R0 resection and T-downstaging rates ranged from 69.2-100% to 47-75% for SCRT-CCT, and 71-92.3% and 41-75% for LCRT, respectively. The regimens had similar compliance, postoperative, and late toxicity, however, acute toxicity rates varied primarily due to differences in treatment protocols. CONCLUSIONS: This review highlights the ability of SCRT-CCT to produce improved tumor response with comparable OS, R0 resection, and T-downstaging at the cost of increased acute toxicity. However, heterogeneity in treatment protocols across studies makes it difficult to provide definitive conclusions regarding the regimen. Several ongoing trials are expected to provide further evidence confirming the findings of RAPIDO trial and detail appropriate SCRT-CCT protocols to improve oncological outcomes, minimize toxicity, and determine its effectiveness as the standard-of-care for locally advanced rectal cancer patients.

Inflammatory myofibroblastic tumor (IMT) is a rare borderline malignancy, usually treated with surgery only. Exceedingly rare cases of inoperable, recurrent, or metastatic IMTs pose a therapeutic challenge. We report successful treatment of a 7-year-old girl with an inoperable anaplastic lymphoma kinase (ALK)-negative IMT of the tongue. The patient underwent various anti-inflammatory (steroids, nonsteroidal anti-inflammatory drugs, clarithromycin) and antiproliferative (chemotherapy) therapies to enable tumor regression and complete resection. Ultimately, next-generation sequencing of the tumor revealed a TFG-ROS-1 translocation, allowing for an off-label targeted therapy with crizotinib. Crizotinib treatment caused slight tumor regression but evident change of its structure, allowing for complete non-mutilating resection. Two histopathology examinations revealed complete disappearance of neoplastic cells following therapy. The patient remains disease-free 22 months after the delayed surgery. In children with inoperable ALK-negative IMTs, molecular testing must be performed to identify other targetable oncogenic fusions, including TFG-ROS1.

INTRODUCTION: Enhanced recovery after bariatric surgery (ERABS) and other fast track protocols are currently being implemented in bariatric surgery. This approach has several benefits. However, early complications may occur and require urgent re-hospitalization and management. Gastrointestinal (GI) bleeding following bariatric surgery remains one of the most serious complications requiring endoscopic treatment. AIM: To evaluate the potential influence of early endoscopic intervention on bariatric patients' management. MATERIAL AND METHODS: A clinical database was searched for patients undergoing endoscopic treatment because of GI tract bleeding following bariatric surgery under the ERABS protocol. 14 out of 1431 patients operated on were identified and their data were extracted for the purposes of this study. Patients readmitted to the hospital due to developing GI tract bleeding (group 2) were compared with patients undergoing endoscopic intervention during the initial stay (group 1), for the same purpose. RESULTS: We found no statistically significant differences in hemoglobin level or length of hospital stay before endoscopy between groups. Based on the analyzed data, the percentage of GI bleeding in patients operated on under the ERABS protocol in our center is 0.97% (n = 14). The rate of early (up to 30 days) readmissions due to GI tract bleeding is 0.4% (n = 5) with an overall early readmission rate of 0.91% (n = 13) in the study period since the ERABS protocol was implemented. CONCLUSIONS: Long-term effects (% total weight loss, %TWL) of bariatric surgery do not depend on the need of early endoscopic intervention and rehospitalization. Endoscopic intervention is a safe treatment modality, not associated with risk of reoperation or complications.
RESUMO
Hypoplastic left heart syndrome is a constellation of malformations which result from the severe underdevelopment of any left-sided cardiac structures. Once considered to be universally fatal, the prognosis for this condition has tremendously improved over the past four decades since the work of William Norwood in the early 1980s. Today, a staged surgical approach is applied for palliating this distinctive cohort of patients, in which they undergo three operative procedures in the first 10 years of their life. Advancements in medical technologies, surgical techniques, and our growing experience in the management of HLHS have made survival into adulthood a possibility. Through this review, we present the different phases of the staged approach with primary focus on stage 1-its modifications, current technique, alternatives, and latest outcomes.
RESUMO
An aortopulmonary window is known to be associated in 5% of interrupted aortic arch cases. The combination of these lesions with a bovine-type aortic arch is much more uncommon. We report its embryological explanation and successful single-stage surgical repair in a three-month-old infant.
