The aim of the study was to compare histological features, postoperative outcomes, and long-term prognostic factors after pancreaticoduodenectomy for distal cholangiocarcinoma and pancreatic ductal adenocarcinoma. From 2005 to 2017, 188 pancreaticoduodenectomies (pancreatic ductal adenocarcinoma n = 151, distal cholangiocarcinoma n = 37) were included. Postoperative outcomes were compared after matching on pancreatic gland texture and main pancreatic duct size. Matching according to tumor size, lymph node invasion and resection margin was used to compare overall and disease-free survival. Distal cholangiocarcinoma patients had more often "soft" pancreatic gland (P = 0.002) and small size main pancreatic duct (P = 0.001). Pancreatic ductal adenocarcinoma patients had larger tumors (P = 0.009), and higher lymph node ratio (P = 0.017). Severe morbidity (P = 0.023) and clinically relevant pancreatic fistula (P = 0.018) were higher in distal cholangiocarcinoma patients. After matching on gland texture and main pancreatic duct diameter, clinically relevant postoperative pancreatic fistula was still more frequent in distal cholangiocarcinoma patients (P = 0.007). Tumor size > 20 mm was predictive of impaired overall survival (P = 0.024) and disease-free survival (P = 0.003), tumor differentiation (P = 0.027) was predictive of impaired overall survival. Survival outcomes for distal cholangiocarcinoma and pancreatic ductal cholangiocarcinoma were similar after matching patients according to tumor size, lymph node invasion and resection margin. Long-term outcomes after pancreaticoduodenectomy for distal cholangiocarcinoma and pancreatic ductal adenocarcinoma patients are similar. Postoperative course is more complicated after pancreaticoduodenectomy for distal cholangiocarcinoma than pancreatic ductal adenocarcinoma. After pancreaticoduodenectomy, patients with distal cholangiocarcinoma and pancreatic ductal adenocarcinoma have similar long-term oncological outcomes.

Objectives: The only treatment with curative potential for distal cholangiocarcinoma (dCCA) is radical surgery which can be complemented with adjuvant chemotherapy. The aim of the present study was to perform an independent external validation of a prognostic model for 3-year overall survival based on routine clinicopathological variables for patients treated with pancreatoduodenectomy for dCCA.
Materials And Methods: All patients with a histopathological confirmed dCCA that underwent pancreatoduodenectomy in Sweden from 2009 through 2019 were identified in the Swedish National Registry for Pancreatic and Periampullary Cancer.

Background/objective: Patient-derived organoids (PDOs) have emerged as essential for ex vivo modelling for pancreatic cancer (PDAC) but reports on efficacy and organoid take rate are scarce. This study aimed to assess the feasibility of establishing PDOs from resected specimens in periampullary tumors.
Methods: Patients undergoing surgery for suspected periampullary cancer were included.

Surgical resection is the only curative treatment for cholangiocarcinoma, but it is often diagnosed at advanced stages, making surgical resection infeasible. Recently, the concept of conversion surgery has expanded the indications for surgical treatment, thanks to advancements in both perioperative management and chemotherapy. However, it remains unclear which patients benefit most from this treatment strategy.

Background: Obstructive jaundice is a common health challenge in daily clinical practice caused by a heterogeneous group of benign and malignant conditions in or around extrahepatic bile ducts. This study aimed to investigate the causes of obstructive jaundice, analyze the age and sex distribution, and report the locations of obstruction.
Methods: This was a retrospective study of electronic records of patients diagnosed with obstructive jaundice in the Hadhramout region in Yemen.

Background: This study compared short- and mid-term outcomes of hemihepatectomy (HH) and pancreatoduodenectomy (PD) in patients with extrahepatic cholangiocarcinoma, focusing on surgical outcomes, body composition, and nutritional status.
Method: A retrospective review was conducted to assess short-term outcomes, including operative time, blood loss, complications, and mortality. Body composition and nutritional parameters were analyzed preoperatively and 1 year postoperatively.
