Hepatic Vein and Inferior Vena Cava Reconstruction during Hepatic Surgery Resection for Cancer
No full textInvasion of tumor in the liver requires surgical interventions that may reduce the effects or may eliminate the tumor-affected cells. The renewal of the hepatic vein and inferior vena cava has enabled most specialized oncologists and medical specialists to use advanced diagnostic methods in the treatment of the liver tumors. Liver resection has prolonged the lives of many patients and the invention of live donor organ transplants has effectively enabled the use of liver resection in most cancer centers across the world. By reviewing data from 10 articles, 21 surgical analyses were investigated and analyzed for the risks involved in the applications of reconstructions of hepatic vein and inferior vena cava in the surgical liver resection. The postoperative complications and the indications of reconstructions were mentioned. The results indicated that with these surgical procedures, complications are still involved but may be successful for particular patients
Von Hippel-Lindau is Associated to Pancreatic Neuroendocrine Tumors: A Comprehensive Review
No full textMultiorgan tumors are a hallmark of the autosomal dominant genetic disorder known as Von Hippel-Lindau syndrome (VHL), which is typically the result of inherited aberrations of the VHL tumor suppressor gene. The most frequent cancer is retinoblastoma, which can also occur in the brain and spinal cord, renal clear cell carcinoma (RCCC), paraganglioma, and neuroendocrine tumors. There may also be lymphangiomas, epididymal cysts, and pancreatic cysts or pancreatic neuroendocrine tumors (pNETs). The most frequent causes of death are metastasis from RCCC and neurological complications from retinoblastoma or central nervous system (CNS). Pancreatic cysts are present in 35–70% of VHL patients. Simple cysts, serous cysts, or pNETs are possible presentations, and the likelihood of malignant degeneration or metastasis is no greater than 8%. Although VHL has been associated with pNETs, their pathological characteristics are unknown. Furthermore, it is unknown whether variations in the VHL gene cause the development of pNETs. Hence, this retrospective study was undertaken with the main aim to examine whether pNETs are connected to VHL from a surgical perspective
Ex vivo Resection for Renal Cancer: Indications and Results in Specific Clinical Scenarios
No full textTo retrospectively evaluate databases for indications and results of “bench surgery technique” in ex vivo or ex situ renal cancer resection as a lost alternative of savage renal function in renal malignancy or benign large tumors.
We retrospectively evaluated PUBMED databases, including studies from 1980 to 2020. Only very few studies had analyzed “ex vivo [and] ex situ renal resection, extracorporeal renal resection, [and] renal autotransplantation.”
Ex vivo renal resection and autotransplantation is the last chance in patients with renal cancer, but manifests numerous difficulties during and after the surgery. However, we noted that in some patients it provided good control over cancer, prevented long-term dialysis, and avoided renal transplantation, thus giving patients a good quality of life
Advancing Minimally Invasive Surgery: Robotic Adrenalectomy for Pheochromocytoma—Efficacy, Safety, and Cost-Effectiveness in Focus
No full textPheochromocytoma, a rare neuroendocrine tumor of the adrenal glands, drives excessive catecholamine production, precipitating hypertension, cardiovascular crises, and systemic symptoms. Laparoscopic adrenalectomy has long been the surgical gold standard, but robotic adrenalectomy is increasingly recognized as a precise, minimally invasive alternative with potential advantages in recovery and operative precision. This narrative review critically evaluates the efficacy, safety, and cost-effectiveness of robotic adrenalectomy for pheochromocytoma, synthesizing evidence from clinical studies to compare perioperative outcomes, complications, and economic impacts against laparoscopic approaches. While robotic techniques demonstrate promising short-term results, including reduced blood loss and shorter hospital stays, the analysis identifies gaps in long-term outcome data and potential publication bias favoring newer technologies. This review underscores the necessity for rigorous prospective studies to validate these findings and refine patient selection criteria. By contextualizing robotic adrenalectomy within the evolving landscape of minimally invasive surgery, this work aims to guide clinical practice, optimize resource allocation, and improve patient-centered care
Reparação Laparoscópica Versus Aberta da Hérnia Inguinal Estrangulada: Uma Revisão Sistemática e Meta-Análise
No full textIntroduction: Strangulated inguinal hernia is a surgical emergency requiring prompt intervention. The choice between laparoscopic and open repair remains controversial, with limited evidence comparing outcomes in the context of strangulation. This study aims to compare the efficacy, safety, and postoperative outcomes of laparoscopic versus open repair for strangulated inguinal hernia.
Methods: A systematic review and meta-analysis were conducted following PRISMA guidelines. Databases including PubMed, Embase, and Cochrane Library were searched for studies comparing laparoscopic and open repair for strangulated inguinal hernia. Primary outcomes included operative time, postoperative complications, length of hospital stay, and recurrence rates. Secondary outcomes included mortality and conversion rates. Statistical analysis was performed using RevMan 5.4, with Egger’s test used to assess publication bias.
Results: Ten studies involving 1250 patients were included. Laparoscopic repair was associated with shorter hospital stays (mean difference: -1.2 days, 95% CI: -1.8 to -0.6, p < 0.001) and lower rates of wound infections (OR: 0.45, 95% CI: 0.28–0.72, p = 0.001). However, operative time was longer in the laparoscopic group (mean difference: 15.3 minutes, 95% CI: 8.2–22.4, p < 0.001). No significant differences were observed in recurrence rates, mortality, or bowel resection rates. Egger’s test indicated no significant publication bias (p = 0.12).
Conclusion: Laparoscopic repair for strangulated inguinal hernia is associated with shorter hospital stays and fewer wound infections but requires longer operative times compared to open repair. Both techniques are comparable in terms of recurrence and mortality rates.Introdução: A hérnia inguinal estrangulada é uma emergência cirúrgica que requer intervenção imediata. A escolha entre a reparação laparoscópica e a reparação aberta continua a ser controversa, com evidência limitada na comparação dos resultados no contexto do estrangulamento. Este estudo tem como objetivo comparar a eficácia, segurança e resultados pós-operatórios da reparação laparoscópica versus a reparação aberta da hérnia inguinal estrangulada.
Métodos: Foi realizada uma revisão sistemática e meta-análise de acordo com as diretrizes PRISMA. Foram pesquisadas bases de dados, incluindo PubMed, Embase e Cochrane Library, para estudos que compararam a reparação laparoscópica e aberta da hérnia inguinal estrangulada. Os desfechos primários incluíram o tempo operatório, complicações pós-operatórias, duração da hospitalização e taxas de recorrência. Os desfechos secundários incluíram mortalidade e taxas de conversão. A análise estatística foi realizada com o software RevMan 5.4, e o teste de Egger foi utilizado para avaliar o viés de publicação.
Resultados: Foram incluídos dez estudos, envolvendo um total de 1250 doentes. A reparação laparoscópica esteve associada a uma menor duração da hospitalização (diferença média: -1,2 dias, IC 95%: -1,8 a -0,6, p < 0,001) e a menores taxas de infeção da ferida cirúrgica (OR: 0,45, IC 95%: 0,28–0,72, p = 0,001). No entanto, o tempo operatório foi mais longo no grupo laparoscópico (diferença média: 15,3 minutos, IC 95%: 8,2–22,4, p < 0,001). Não foram observadas diferenças significativas nas taxas de recorrência, mortalidade ou resseção intestinal. O teste de Egger não indicou viés de publicação significativo (p = 0,12).
Conclusão: A reparação laparoscópica da hérnia inguinal estrangulada está associada a uma menor duração da hospitalização e a menores taxas de infeção da ferida cirúrgica, mas requer um tempo operatório mais longo em comparação com a reparação aberta. Ambas as técnicas apresentam resultados semelhantes em termos de taxas de recorrência e mortalidade
Narrative Review of Von Hippel-Lindau Syndrome: From Discovery to Modern Medical and Surgical Therapies
No full textThe von Hippel-Lindau (VHL) syndrome is a rare autosomal dominant disorder caused by mutations in the VHL tumor suppressor gene, leading to the development of benign and malignant tumors in multiple organs, including the kidneys, brain, spine, retina, and pancreas. Since its initial description in the early 20th century, significant progress has been made in understanding its pathogenesis, genetic basis, and clinical management. This narrative review provides a comprehensive overview of VHL syndrome, from its discovery to the latest medical and surgical therapies. A systematic literature review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, incorporating the Egger test to assess publication bias. The review highlights the evolution of diagnostic criteria, the role of genetic testing, and the development of targeted therapies such as hypoxia-inducible factor 2-alpha (HIF-2α) inhibitors. Surgical interventions, including nephron-sparing surgery and minimally invasive techniques, are also discussed. This review emphasizes the importance of a multidisciplinary approach to managing VHL syndrome and explores emerging therapies that hold promise for improving patient outcomes
State-of-the-art of Esophagectomy for Cancer: From Open to Laparoscopic and Robotic Technique
No full textINTRODUCTION: The results for the meta-analytical review, which contrasted laparoscopic or robotically assisted esophagectomy for cancer against open esophagectomy (OE), indicated feasibility and safety associated with the robotic method.
AIM: The objective of this study is to review the current literature on MIE (Laparo-thoracoscopic and Robotic approach) and open approach and check the state-of-the-art of esophagectomy for cancer.
MATERIALS AND METHODS: The comparison of studies which contrasted laparoscopic or robotically assisted esophagectomy for cancer against open esophagectomy (OE).
RESULTS: This review represented the largest sequence of mini-invasive esophagectomy (MIE) to date and the results appear to be comparable to those attained by the traditional open approach. MIE constitutes a safe procedure with a learning curve of around 36 cases.
CONCLUSION: The studies did not reveal variations in mortality and morbidity rate, conversion rate, intensive care unitstay, 1-month mortality, and post-operative complications between the mini-invasive esophagectomy cohort and OE cohort
