RESUMO

Although elective laparoscopic cholecystectomy is a common surgical procedure, it can become challenging due to multiple variants of the anatomy of both cystic artery and cystic bile duct. A 52-year-old male with a history of symptomatic cholelithiasis underwent elective laparoscopic cholecystectomy. During preparation of the Calot's triangle in order to achieve the "critical view of safety", an uncommon variation of the arterial anatomy was detected. The cystic artery was found to be originating from a robust middle hepatic artery instead of the right hepatic artery. The retrograde manner of cholecystectomy helped the visualization and protection of the middle hepatic artery. This anatomic finding was confirmed per CT done postoperatively. This case constitutes a rare arterial variation, in which the cystic artery arises from the middle hepatic artery, the artery that supplies the hepatic segment IV, which itself constituted a rare variation, since it arose from the anterior branch of the right hepatic artery. This artery could be falsely ligated instead of the real cystic artery. Certain techniques can be used to enhance the surgeon's ability to distinguish and safely ligate the proper entities. Anatomic knowledge of the possible variations of arterial and bile vessels is crucial for intraoperative recognition. Dissection of the Calot's triangle and reassurance of the "critical view of safety" are mandatory dissection techniques during laparoscopic cholecystectomy. Additionally, the retrograde manner of cholecystectomy can be of significant help in case of unclear anatomy in order to avoid ligation of uncertain entities during dissection.

RESUMO

Cholecystoduodenal fistula (CDF) is an uncommon condition characterized by an abnormal connection between the gallbladder and the duodenum, often linked to cholelithiasis. It typically presents with nonspecific symptoms such as abdominal pain and jaundice but can occasionally result in severe upper gastrointestinal (GI) bleeding. This report describes the case of a 94-year-old female who presented with hypovolemic shock and multiple episodes of hematemesis. An upper GI endoscopy confirmed a CDF with active hemorrhage. Due to her comorbidities and poor performance status, an endoscopic approach using hemostatic spray was chosen, resulting in a favorable clinical outcome. The development of CDF is typically a result of chronic gallbladder inflammation and cholecystitis, leading to adhesion and erosion into the duodenum. Diagnosis involves imaging and endoscopic techniques, and management varies based on the patient's condition, encompassing surgical, endoscopic, or conservative approaches. This case highlights the necessity of considering CDF in the differential diagnosis of upper GI bleeding, especially in patients with recurrent cholecystitis, and emphasizes the importance of individualized management strategies. It is notable for the use of a minimally invasive endoscopic technique to manage a high-risk patient, highlighting an alternative to surgical intervention.

RESUMO

INTRODUCTION: Esophageal inflammatory fibroid polyp (IFP) is a rare benign tumor of the gastrointestinal tract with limited available data on clinicopathologic features and treatment strategies. EVIDENCE ACQUISITION: A systematic review of the literature in PubMed/Medline and Scopus databases was performed for articles concerning esophageal IFP in adult population. EVIDENCE SYNTHESIS: A total of 16 studies were identified, involving 16 patients with a Male-Female Ratio of 3:1 and mean age of 50.38 years. Clinical presentation of esophageal IFP included progressive dysphagia in 56.3% of cases, with additional symptoms such as epigastric and retrosternal pain, weight loss, vomiting, and melena. Diagnostic modalities involved endoscopy in all cases, with endoscopic ultrasound (EUS) employed in 50% of cases and tissue biopsy performed during endoscopy in 87.5% of the patients. Therapeutic approach of esophageal IFP consisted of surgical resection in 75% of the patients and endoscopic resection in the remaining 25%, with various surgical procedures employed based on tumor location. Follow-up data, available for 11 patients over a median duration of 15.5 months, indicated two instances of recurrence following endoscopic resection, while the other nine patients remained asymptomatic with no evidence of recurrence. CONCLUSIONS: Esophageal IFP is a rare benign tumor of the gastrointestinal tract presenting with dysphagia, regurgitation, and heartburn. Resection, either endoscopic or surgical, is the primary treatment approach. Prognosis for esophageal IFP is favorable, with low recurrence rates. Further research is required to investigate potential risk factors and etiology for this lesion, and to explore novel therapeutic approaches that may improve patient outcomes.

RESUMO

The impact of sex on the prognosis of patients with esophageal cancer remains unclear. Evidence supports that sex- based disparities in esophageal cancer survival could be attributed to sex- specific risk exposures, such as age at diagnosis, race, socioeconomic status, smoking, drinking, and histological type. The aim of our study is to investigate the role of sex disparities in survival of patients who underwent surgery for esophageal cancer. A systematic review and meta-analysis of the existing literature in PubMed, EMBASE, and CENTRAL from December 1966 to February 2023, was held. Studies that reported sex-related differences in survival outcomes of patients who underwent esophagectomy for esophageal cancer were identified. A total of 314 studies were included in the quantitative analysis. Statistically significant results derived from 1-year and 2-year overall survival pooled analysis with Relative Risk (RR) 0.93 (95% Confidence Interval (CI): 0.90-0.97, I2 = 52.00) and 0.90 (95% CI: 0.85-0.95, I2 = 0.00), respectively (RR < 1 = favorable for men). In the postoperative complications analysis, statistically significant results concerned anastomotic leak and heart complications, RR: 1.08 (95% CI: 1.01-1.16) and 0.62 (95% CI: 0.52-0.75), respectively. Subgroup analysis was performed among studies with <200 and > 200 patients, histology types, study continent and publication year. Overall, sex tends to be an independent prognostic factor for esophageal carcinoma. However, unanimous results seem rather obscure when multivariable analysis and subgroup analysis occurred. More prospective studies and gender-specific protocols should be conducted to better understand the modifying role of sex in esophageal cancer prognosis.

RESUMO

The incidence of T4b esophageal cancer with aortic invasion but without distant metastasis is estimated to be between 3.8% and 4.6% of all esophageal cancer cases. Development of an aortoesophageal fistula in such cases is a rare but not unlikely event, leading to catastrophic consequences. The aim of this systematic review is to evaluate the importance of aortic stenting (Thoracic Endovascular Aortic Repair-TEVAR) and its optimal timing in the management of locally advanced esophageal cancer. A systematic literature search of the MEDLINE, Scopus, and Google Scholar databases was undertaken to identify relevant studies published up to March 2024. An individual patient data analysis was performed by forming a patient cohort with elective and salvage TEVAR subgroups, depending on the timing of the stenting. The study pool consisted of 25 studies incorporating 101 cases of locally advanced esophageal cancer, with a median age of 64 years (range 45-87 years). Of them, 50 patients underwent elective TEVAR compared with 51 patients receiving TEVAR in an acute salvage setting. Elective or prophylactic TEVAR was found to significantly increase esophageal resection rates (65.6% vs. 16.7% in the salvage subgroup, P < 0.001), concurrently reducing complication rates (8.3% vs. 36.1%, P < 0.001). Overall survival was also prolonged in the elective subgroup (8.3 vs. 4 months, P = 0.001), with elective stenting being the only independent predictor of improved survival. In conclusion, management with aortic stenting in high-risk patients may reduce the catastrophic consequences of massive bleeding, minimize complications, and enhance survival rates.

RESUMO

Primary hydatid cysts (PHCs) in the extremities are uncommon, presenting in the majority of cases with atypical clinical features. Radical surgical excision remains the mainstay of treatment. The aim of our study was to accumulate the already published data on PHCs in the extremities in terms of demographic, diagnostic, and therapeutic aspects. Three electronic databases were meticulously searched for articles published until 2024. A total of 85 studies comprising 118 patients were finally included in our review. Sixteen patients (13.5%) were diagnosed with a hydatid cyst in their upper extremity, 94 (79.7%) with a PHC in the lower extremity, and eight (6.8%) with an echinococcal cyst in the axilla. Pain and swelling were the most frequent symptoms, whereas only two patients were completely asymptomatic. The mean lesion size was 11.6 ± 7.1 cm. Preoperative serology investigation was reported in 82 out of 118 (69.5%) patients; among them, 33 (44.6%) cases had a positive preoperative serology test. The vast majority of patients (96.6%) were treated with an interventional procedure either surgical or radiological, and only seven experienced postoperative complications. No anaphylactic reaction was described perioperatively. Although preoperative diagnosis of PHCs is challenging, they should be considered in the differential diagnosis of soft tissue lesions. Treatment strategies should be individualized on a patient basis, while radical surgical excision remains the gold standard treatment.

RESUMO

PURPOSE: Spigelian Hernia (SH) is characterized by the protrusion of abdominal viscera or preperitoneal fat through a defect in the spigelian aponeurosis. The objective of this systematic review was to evaluate current literature on Spigelian Hernias in adult population and elucidate their characteristics and preferable management. METHODS: MEDLINE and Scopus bibliographical databases were systematically searched (last search: 31st January 2024) for studies concerning SHs. RESULTS: Two hundred and thirty-four articles met predefined inclusion criteria and concerned collectively 1,629 patients with SHs (58.7% females) with an age of 62.32 ± 17.71 (mean ± SD) years and a BMI of 28.56 ± 7.34 (mean ± SD) kg/m2. A minimally invasive approach was opted at 46.8% of cases, while a mesh was implemented at 67.9% of cases. Postoperative length of hospital stay was 2.8 ± 2.9 (mean ± SD) days. Following individual cases analysis, open surgery was preferable at emergency setting (OR: 2.45; 95% CI: 1.36-4.41; p-value: 0.003), and minimally invasive approaches were associated with shorter length of hospital stay [2 (1-9) vs. 5 (1-22) days; p-value: <0.001]. Overall, thirty-day postoperative morbidity and mortality rates reached 7.0% and 0.3% respectively. CONCLUSION: SH is a rare ventral hernia, and it concerns most frequently overweight women. Open surgical approach is preferred in emergency cases, while laparoscopic surgery is associated with shorter hospitalization. Further comparative studies are necessary to determine optimal surgical approach.

RESUMO

RATIONALE AND OBJECTIVES: Surgery in combination with chemo/radiotherapy is the standard treatment for locally advanced esophageal cancer. Even after the introduction of minimally invasive techniques, esophagectomy carries significant morbidity and mortality. One of the most common and feared complications of esophagectomy is anastomotic leakage (AL). Our work aimed to develop a multimodal machine-learning model combining CT-derived and clinical data for predicting AL following esophagectomy for esophageal cancer. MATERIAL AND METHODS: A total of 471 patients were prospectively included (Jan 2010-Dec 2022). Preoperative computed tomography (CT) was used to evaluate celia trunk stenosis and vessel calcification. Clinical variables, including demographics, disease stage, operation details, postoperative CRP, and stage, were combined with CT data to build a model for AL prediction. Data was split into 80%:20% for training and testing, and an XGBoost model was developed with 10-fold cross-validation and early stopping. ROC curves and respective areas under the curve (AUC), sensitivity, specificity, PPV, NPV, and F1-scores were calculated. RESULTS: A total of 117 patients (24.8%) exhibited post-operative AL. The XGboost model achieved an AUC of 79.2% (95%CI 69%-89.4%) with a specificity of 77.46%, a sensitivity of 65.22%, PPV of 48.39%, NPV of 87.3%, and F1-score of 56%. Shapley Additive exPlanation analysis showed the effect of individual variables on the result of the model. Decision curve analysis showed that the model was particularly beneficial for threshold probabilities between 15% and 48%. CONCLUSION: A clinically relevant multimodal model can predict AL, which is especially valuable in cases with low clinical probability of AL.

RESUMO

BACKGROUND AND AIM: Hepatocellular carcinoma (HCC) diagnosis mainly relies on its pathognomonic radiological profile, obviating the need for biopsy. The project of incorporating artificial intelligence (AI) techniques in HCC aims to improve the performance of image recognition. Herein, we thoroughly analyze and evaluate proposed AI models in the field of HCC diagnosis. METHODS: A comprehensive review of the literature was performed utilizing MEDLINE/PubMed and Web of Science databases with the end of search date being the 30th of September 2023. The MESH terms "Artificial Intelligence," "Liver Cancer," "Hepatocellular Carcinoma," "Machine Learning," and "Deep Learning" were searched in the title and/or abstract. All references of the obtained articles were also evaluated for any additional information. RESULTS: Our search resulted in 183 studies meeting our inclusion criteria. Across all diagnostic modalities, reported area under the curve (AUC) of most developed models surpassed 0.900. A B-mode US and a contrast-enhanced US model achieved AUCs of 0.947 and 0.957, respectively. Regarding the more challenging task of HCC diagnosis, a 2021 deep learning model, trained with CT scans, classified hepatic malignant lesions with an AUC of 0.986. Finally, a MRI machine learning model developed in 2021 displayed an AUC of 0.975 when differentiating small HCCs from benign lesions, while another MRI-based model achieved HCC diagnosis with an AUC of 0.970. CONCLUSIONS: AI tools may lead to significant improvement in diagnostic management of HCC. Many models fared better or comparable to experienced radiologists while proving capable of elevating radiologists' accuracy, demonstrating promising results for AI implementation in HCC-related diagnostic tasks.

RESUMO

BACKGROUND: The COVID-19 pandemic has disrupted global daily life, including the world of elite athletes. This paper examines the multifaceted impact the COVID-19 pandemic had on elite swimmers and water polo athletes, specifically their mental health, their concerns over the virus, their intentions of getting vaccinated, and sleep disturbances that they may have faced. METHODS: We conducted a cross-sectional study on elite swimmers and water polo players, using an anonymous questionnaire. RESULTS: A total of 200 elite athletes participated. The majority of the participants reported a negative impact on their mental health, screened positive for insomnia (n = 107 (53.5%), with females (n = 101; 57.7%), swimmers (n = 100, 66.7%), and university students (n = 71, 71.7%) being more vulnerable (p < 0.001). Concerns about contracting the disease especially during important training or tournament periods and potential career disruption also affected their psychological well-being. While the majority (75%) had the intention of getting vaccinated, an alarming percentage was yet uncertain over its decision. CONCLUSIONS: This study highlights the significant psychological distress faced by elite aquatic athletes during the pandemic. It emphasizes the difficulties faced by elite swimmers and water polo athletes and determines not only the importance of addressing the vaccination intentions of athletes, but also how critical it is to confront the challenges they face both for their personal health and for the restoration of world sports to their pre-pandemic state. More large-scale studies are required to inform policies targeted at minimizing disruption to the athletes' career, provision of information on preventive measures and vaccination, and improvement in psychological well-being in case of similar major public health issues in the future. Additionally, this study calls for further research to explore the unique challenges faced by aquatic athletes, such as those related to their training environments and fear of contagion, to better support them in future public health crises.

RESUMO

INTRODUCTION: The role of stereotactic body radiation therapy (SBRT) as a locally effective therapeutic approach for liver oligometastases from tumors of various origin is well established. We investigated the role of robotic SBRT (rSBRT) treatment on oligometastatic patients with liver lesions. MATERIAL AND METHODS: This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The PubMed and Scopus databases were accessed by two independent investigators concerning robotic rSBRT for liver metastases, up to 3 October 2023. RESULTS: In total, 15 studies, including 646 patients with 847 lesions that underwent rSBRT, were included in our systematic review. Complete response (CR) after rSBRT was achieved in 40.5% (95% CI, 36.66-44.46%), partial response (PR) in 19.01% (95% CI, 16.07-22.33%), whereas stable disease (SD) was recorded in 14.38% (95% CI, 11.8-17.41%) and progressive disease (PD) in 13.22% (95% CI, 10.74-16.17%) of patients. Progression-free survival (PFS) rates at 12 and 24 months were estimated at 61.49% (95% CI, 57.01-65.78%) and 32.55% (95% CI, 28.47-36.92%), respectively, while the overall survival (OS) rates at 12 and 24 months were estimated at 58.59% (95% CI, 53.67-63.33%) and 44.19% (95% CI, 39.38-49.12%), respectively. Grade 1 toxicity was reported in 13.81% (95% CI, 11.01-17.18%), Grade 2 toxicity in 5.57% (95% CI, 3.82-8.01%), and Grade 3 toxicity in 2.27% (955 CI, 1.22-4.07%) of included patients. CONCLUSIONS: rSBRT represents a promising method achieving local control with minimal toxicity in a significant proportion of patients. Further studies are needed to evaluate the role of rSBRT in the management of metastatic liver lesions.

RESUMO

BACKGROUND: Real-time prediction of the remaining surgery duration (RSD) is important for optimal scheduling of resources in the operating room. METHODS: We focus on the intraoperative prediction of RSD from laparoscopic video. An extensive evaluation of seven common deep learning models, a proposed one based on the Transformer architecture (TransLocal) and four baseline approaches, is presented. The proposed pipeline includes a CNN-LSTM for feature extraction from salient regions within short video segments and a Transformer with local attention mechanisms. RESULTS: Using the Cholec80 dataset, TransLocal yielded the best performance (mean absolute error (MAE) = 7.1 min). For long and short surgeries, the MAE was 10.6 and 4.4 min, respectively. Thirty minutes before the end of surgery MAE = 6.2 min, 7.2 and 5.5 min for all long and short surgeries, respectively. CONCLUSIONS: The proposed technique achieves state-of-the-art results. In the future, we aim to incorporate intraoperative indicators and pre-operative data.

RESUMO

Defining predictive biomarkers for targeted therapies and optimizing anti-tumor immune response is a main challenge in ongoing investigations. Progastrin has been studied as a potential biomarker for detecting and diagnosing various malignancies, and its secretion has been associated with cell proliferation in the gastrointestinal tract that may promote tumorigenesis. Progastrin is a precursor molecule of gastrin, synthesized as pre-progastrin, converted to progastrin after cleavage, and transformed into amidated gastrin via biosynthetic intermediates. In cancer, progastrin does not maturate in gastrin and becomes a circulating and detectable protein (hPG80). The development of cancer is thought to be dependent on the progressive dysregulation of normal signaling pathways involved in cell proliferation, thus conferring a growth advantage to the cells. Understanding the interaction between progastrin and the immune system is essential for developing future cancer strategies. To that end, the present review will approach the interlink between gastrointestinal cancers and progastrin by exploring the underlying molecular steps involved in the initiation, evolution, and progression of gastrointestinal cancers. Finally, this review will focus on the clinical applications of progastrin and investigate its possible use as a diagnostic and prognostic tumor circulating biomarker for disease progression and treatment effectiveness, as well as its potential role as an innovative cancer target.

RESUMO

The purpose of this article is to present a well-known physician and highlight his contribution into an essential, but neglected anatomical feature. George Sclavunos (1869-1954) was a 20th century Greek physician, whose scientific work was a significant milestone in global medical knowledge. In 1899 he became Professor of Anatomy and Head Director of the Department of Anatomy. In 1906 Sclavunos G. published the first volume of the three volume book "Human Anatomy" (1906-1926), which is characterized by its unparalleled illustrations. For more than a century it was the most important book of medical literature in Greece. In 1926 he became a Full Member of the Academy of Athens and was named Life Partner of the International Anatomical Society. His interests included Anatomy, Physiology, Histology, as well as Osteology and Syndesmology. In his book "Human Anatomy", he described for first time the "Sialine Groove of the Stomach", which was described by Waldeyer-Hartz almost at the same time as the "Magenstrasse", a German word that means "stomach road". It is a ribbon-like path that extends along the lesser curvature of the stomach from the gastric cardia to the antrum and releases the gastric content directly into the small intestine. Its importance is confirmed by its association not only with drug delivery, but also with anti-obesity surgical techniques. The old German term has come back into common medical usage in view of the commonly performed Magenstrasse and Mill procedure, a form of bariatric surgery. CONCLUSION: Sclavunos G. managed to observe an anatomical structure that has remained of great importance until today.

RESUMO

Background: Anastomotic leak remains a dreaded complication in colorectal surgery. Identifying optimal techniques that minimize its incidence is an active area of investigation. The aim of this experimental study was to evaluate the effect of commonly used hemostatic products on the integrity of colonic anastomoses. Methods: Male Wistar rats were randomized into 4 groups. In the control group (A), the anastomosis was performed using the standard hand-sewn technique in the ascending colon. In group B the hand-sewn technique was reinforced with a collagen-fibrinogen patch, in group C with fibrin glue, and in group D with a polyethylene glycol (PEG)-coated oxidized cellulose patch. On the 7th postoperative day, anastomotic bursting pressure measurements were obtained. A specimen surrounding the anastomosis was retrieved for histopathologic evaluation. Results: Of the 19 rats, 17 survived and 15 were included in the analysis (5 in each of groups A, B and C). Testing in group D was discontinued following adverse events in the preliminary experiments. The mean bursting pressure of the anastomosis was significantly higher in the control group (A: 221±19.41 mmHg, B: 151±14.42 mmHg, and C: 112±13.57 mmHg; P=0.001). Anastomotic healing parameters were not different between groups. Conclusions: Although experimental data support the use of sealants in defective anastomoses, in this study the reinforcement of colonic anastomosis with fibrin or oxidized cellulose-PEG sealants did not improve either bursting pressure values or anastomotic healing. More data from robust anastomoses of animals and humans are needed before sealing becomes common clinical practice in colorectal surgery.

RESUMO

Esophageal cancer (EC) remains a formidable malignancy with limited treatment options and high mortality rates, necessitating the exploration of innovative therapeutic avenues. Through a systematic analysis of a multitude of studies, we synthesize the diverse findings related to metformin's influence on EC. This review comprehensively elucidates the intricate metabolic pathways and molecular mechanisms through which metformin may exert its anti-cancer effects. Key focus areas include its impact on insulin signaling, AMP-activated protein kinase (AMPK) activation, and the mTOR pathway, which collectively contribute to its role in mitigating esophageal cancer progression. This review critically examines the body of clinical and preclinical evidence surrounding the potential role of metformin, a widely prescribed anti-diabetic medication, in EC management. Our examination extends to the modulation of inflammation, oxidative stress and angiogenesis, revealing metformin's potential as a metabolic intervention in esophageal cancer pathogenesis. By consolidating epidemiological and clinical data, we assess the evidence that supports metformin's candidacy as an adjuvant therapy for esophageal cancer. By summarizing clinical and preclinical findings, our review aims to enhance our understanding of metformin's role in EC management, potentially improving patient care and outcomes.

RESUMO

Trauma-related esophageal injuries (TEIs) are a rare but highly lethal condition. The presentation of TEIs is very diverse depending on the location and mechanism of injury (blunt vs. penetrating), as well as the presence or absence of concurrent injuries. The aim of the present systematic review and meta-analysis is to delineate the clinical features impacting TEI management. A systematic review of the Medline, Embase, and web of science databases was undertaken for studies reporting on patients with TEIs. A random effects model was employed in the meta-analysis of aggregated data. Eleven studies, incorporating 4605 patients, were included, with a pooled mortality rate of 19% (95% confidence interval (CI) 13-25%). Penetrating injuries were 34% more likely to occur (RR 0.66, 95% CI 0.49-0.89, P = 0.01), predominantly in the neck compartment. Surgery was employed in 53% of cases (95% CI 32-73%), with 68% of patients having associated injuries (95% CI 43-94%). In terms of choice of surgical repair technique, primary suture repair was most frequently reported, irrespective of injury location. Postoperative drainage was employed in 27% of the cases and was more common following repair of thoracic esophageal injuries. The estimated dependence on mechanical ventilation was 5.91 days (95% CI 5.1-6.72 days), while the length of stay in the intensive care unit averaged 7.89 days (95% CI 7.14-8.65 days). TEIs are uncommon injuries in trauma patients, associated with considerable mortality and morbidity. Open suture repair of ensuing esophageal defects is by large the most employed approach, while stenting may be indicated in carefully selected cases.
