BACKGROUND: Tumor staging plays a pivotal role in melanoma management, where the depth of tumor invasion has been traditionally used as the cornerstone of staging. Paradoxically, the tumor diameter has not been integrated into the staging system. The aim of this study is to elucidate the clinical implications and prognostic value of tumor diameter in cutaneous melanoma, with a particular emphasis on the acral-melanoma predominant East Asian population, thus potentially enriching the clinical evaluation and treatment strategies for cutaneous melanoma...

INTRODUCTION: There are many reasons why orthopaedic surgeons move or change careers. We asked the questions: (1) What is the geographic distribution of orthopaedic surgeons with respect to age, sex, and race and ethnicity? (2) How has our workforce changed over time with regard to these factors? (3) Are there any patterns or trends detected regarding policy or regulatory events that coincide with these differences? METHODS: The American Academy of Orthopaedic Surgeons surveys over 30,000 members, collecting data on demographics, age, race sex, and practice statistics...

The clinical data of 7 patients diagnosed with mixed neuroendocrine-nonneuroendocrine neoplasm were analyzed in the Department of Hepatobiliary Surgery of Hunan Provincial People's Hospital from January 2016 to December 2022. Among the 7 patients, 5 were male and 2 were female, with an average age of 59.3 years. Its clinical characteristics are similar to malignant ampulla tumors, and it is difficult to differentiate them. The preoperative puncture biopsy positivity rate is low, making it difficult to diagnose preoperatively, and the prognosis is worse...

Far-advanced gastric cancer has always been a challenging problem in clinical treatment and a key direction for breakthrough research. Non-surgical treatments are primarily managed in patients with far-advanced gastric cancer. However, with the advancement of therapeutic methods in recent years, tumor foci can be significantly regressed after effective preoperative treatment, in prospect ofregaining the opportunity of radical gastrectomy. In the surgical field, laparoscopic surgery, as one of the routine methods for gastric cancer, has proven effective in the treatment of initially resectable gastric cancer...

With the improvement of oncology diagnosis and treatment, the survival time of cancer patients has been significantly prolonged, and the cancer therapy-related cardiovascular toxicity such as radiotherapy, chemotherapy, immunotherapy, and surgery are becoming more and more prominent, and it is in this context that the germ of Cardio-Oncology exploration has come into being. The multidisciplinary Cardio-Oncology team aims to establish a multidisciplinary prevention and control system to assess patients' baseline risk factors, individualized monitoring, and weighing the risk-benefit ratio of cancer therapy...

TECHNIQUE: Hepatocellular adenoma (HCA) is a benign monoclonal tumour that originates from mature hepatocytes.Liver resection is recommended in case of overt malignant transformation to hepatocellular carcinoma.However, hepatobiliary surgeries are technically challenging in patients with giant HCA (GHCA) owing to the risk of catastrophic intraoperative bleeding and difficulty with its control during laparoscopic treatment. We present a technical note on the utilization of the hepatic vein as anatomical landmarks for laparoscopic removal of giant hepatic glands, without intraoperative ultrasonography and with the aid of an augmented reality navigation system during surgery...

There are many reports on the positional relationship between the ileocolic artery and superior mesenteric vein (SMV). However, there have been no reports of anomalous venous confluence in the ileocecal vessel area. A 69-year-old man was diagnosed with cecal cancer on a preoperative examination of a lung tumor. We planned to perform surgery for the cecal cancer. Computed tomography angiography revealed an anomalous vein confluence in the ileocolic region. We performed robot-assisted ileocecal resection. Although the small intestinal vein was misidentified as the SMV at first, we confirmed the misidentification, identified the SMV on the dorsal side of the ileocolic artery, and ligated the ileocolic vessels with precise forceps manipulation during robotic surgery...

BACKGROUND: Living donor liver transplant (LDLT) is based on the principle of double equipoise. Organ shortage in Asian countries has led to development of high-volume LDLT programs with good outcomes. Safety of live liver donor is the Achilles heel of LDLT program and every effort should be made to achieve low morbidity and near zero mortality rates. METHODS: We retrospectively analyzed our prospectively maintained donor morbidity data (outcomes) of 177 donors in a new transplant program setup in western India by an experienced surgeon...
