A novel transpancreatic mattress suture method using a polyglycolic acid sheet significantly decreased postoperative pancreatic fistula (POPF) rates in robotic distal pancreatectomy. Among 145 cases analyzed, the TP group showed a POPF rate of 5.6%, compared to 27.3% for the hand-sewn and 14.3% for stapler methods. Notably, pancreatic thickness of ≥12 mm was an independent […]

Curative-intent resection significantly boosts survival in cholangiocarcinoma
A retrospective analysis of 720 cholangiocarcinoma patients revealed a 78.3% overall resectability rate, with the highest in perihilar cases. Median survival time was 11.6 months, varying by subtype. Patients undergoing curative-intent resection experienced markedly improved survival rates compared to those receiving palliative treatment. Notably, complete (R0) resection resulted in a five-year survival rate of 20.2%, […]
Fluorescence imaging effectively locates small pancreatic tumors.
Fluorescence imaging using indocyanine green has shown promising results for the intraoperative localization of small pancreatic neuroendocrine tumors. In a case report involving five patients, successful tumor identification and laparoscopic partial resections were achieved without serious complications. Pathological reviews confirmed four neuroendocrine tumors of G1 stage and one case of neuroendocrine cell hyperplasia. The findings […]
New segmentation method significantly improves liver cancer imaging
The DSA-Former network introduces a hybrid approach for segmenting liver and liver tumours, effectively integrating convolutional kernels and attention mechanisms. Achieving dice coefficients of 96.8% for liver segmentation and 72.2% for tumour segmentation, this method outperforms existing techniques in key metrics such as IoU and HD95. Enhanced segmentation precision promises to bolster the accuracy of […]
Adjuvant TACE with Lenvatinib Enhances Survival in HCC Patients
A study involving 346 patients with hepatocellular carcinoma and microvascular invasion demonstrated that adjuvant transcatheter arterial chemoembolization (TACE) combined with lenvatinib significantly improves overall survival and recurrence-free survival compared to no adjuvant therapy. Group one, which received both treatments, showed superior outcomes (overall survival HR 0.321, recurrence-free survival HR 0.319), whereas groups receiving either treatment […]
Machine learning enhances predictions for biliary tract cancer survival.
A novel “biliary tract cancer survival calculator” was developed, utilizing machine learning to provide personalized survival estimates for patients with biliary tract cancers, incorporating data from 62,877 cases. Key factors negatively impacting survival included metastatic disease, age at diagnosis, and lack of surgical treatment. The model demonstrated significant accuracy during internal validation, with a c-index […]
Initial assessments of resectability influence outcomes for colorectal cancer patients
In a study of 1,250 patients with liver-only metastatic colorectal cancer (mCRC), less than half of those initially deemed unresectable achieved successful surgical resection after systemic therapy. Factors such as younger age and better performance status correlated with the likelihood of conversion to resectability. Overall survival rates post-resection significantly exceeded those of non-resected patients across […]
Endoscopic ultrasound effectively characterizes pancreatic cystic lesions.
Enhanced imaging techniques have led to increased detection of pancreatic cystic lesions. A study of 88 patients revealed that endoscopic ultrasound fine needle aspiration (EUS-FNA) allowed for precise characterization of these lesions, with some demonstrating worrisome features requiring surgical intervention. Most patients had a history of pancreatitis, and the majority of lesions were pancreatic pseudocysts. […]
Repeat liver resection improves prognosis for colorectal liver metastasis.
Patients with recurrent colorectal liver metastases who underwent repeat liver resection experienced significantly better long-term outcomes compared to those who did not, with five-year overall survival rates of 66.3% versus 27.2% respectively. Key prognostic factors include having four or more recurrent tumors, tumors larger than 5 cm, and the presence of extrahepatic disease. Prognosis varied […]
New preoperative assessment criteria reduce liver surgery risks
A study involving 150 patients undergoing major hepatectomy for hilar cholangiocarcinoma identified critical risk factors for postoperative liver failure. The combined assessment of future remnant liver volume to total liver volume ratio (frlv/tlv) and indocyanine green clearance fraction (icgk-f) proved effective in predicting complications. Patients with both high-risk factors had a significantly greater incidence of […]
