Although the current standard for resectable pancreatic cancer most commonly includes neoadjuvant chemotherapy prior to a curative resection, surgery, in the majority of patients, has historically been palliative. The latter interventions include open or laparoscopic bypass of the bile duct or stomach in cases of obstructive jaundice or gastric outlet obstruction, respectively. Non-surgical interventional therapies started with percutaneous transhepatic biliary drainage (PTBD), both as a palliative maneuver in unresectable patients with obstructive jaundice and to improve liver function in patients whose surgery was delayed. Likewise, interventional radiologic techniques included the placement of plastic and ultimately self-expandable metal stents (SEMSs) through PTBD tracts in patients with unresectable cancer as well as percutaneous cholecystostomy in patients who developed cholecystitis in the context of malignant obstructive jaundice. Endoscopic retrograde cholangiopancreatography (ERCP) and stent placement (plastic\/SEMS) were subsequently used both preoperatively and palliatively, and this was followed by, or undertaken in conjunction with, endoscopic gastro-duodenal SEMS placement for gastric outlet obstruction. Although endoscopic ultrasound (EUS) was initially used to cytologically diagnose and stage pancreatic cancer, early palliation included celiac block or ablation for intractable pain. However, it took the development of lumen-apposing metal stents (LAMSs) to facilitate a myriad of palliative procedures: cholecystoduodenal, choledochoduodenal, gastrohepatic, and gastroenteric anastomoses for cholecystitis, obstructive jaundice, and gastric outlet obstruction, respectively. In this review, we outline these procedures, which have variably supplanted surgery for the palliation of pancreatic cancer in this rapidly evolving field.<\/jats:p>","DOI":"10.3390\/jcm14144997","type":"journal-article","created":{"date-parts":[[2025,7,15]],"date-time":"2025-07-15T11:52:58Z","timestamp":1752580378000},"page":"4997","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The Palliation of Unresectable Pancreatic Cancer: Evolution from Surgery to Minimally Invasive Modalities"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5219-6277","authenticated-orcid":false,"given":"Muaaz","family":"Masood","sequence":"first","affiliation":[{"name":"Division of Gastroenterology and Hepatology, Center for Digestive Health, Virginia Mason Franciscan Health, Seattle, WA 98101, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shayan","family":"Irani","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology and Hepatology, Center for Digestive Health, Virginia Mason Franciscan Health, Seattle, WA 98101, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-4943-4816","authenticated-orcid":false,"given":"Mehran","family":"Fotoohi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Virginia Mason Franciscan Health, Seattle, WA 98101, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lauren","family":"Wancata","sequence":"additional","affiliation":[{"name":"Department of Surgery, Virginia Mason Franciscan Health, Seattle, WA 98101, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajesh","family":"Krishnamoorthi","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology and Hepatology, Center for Digestive Health, Virginia Mason Franciscan Health, Seattle, WA 98101, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9745-7538","authenticated-orcid":false,"given":"Richard A.","family":"Kozarek","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology and Hepatology, Center for Digestive Health, Virginia Mason Franciscan Health, Seattle, WA 98101, USA"},{"name":"Center for Interventional Immunology, Benaroya Research Institute, Virginia Mason Franciscan Health, Seattle, WA 98101, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Lambert, A., Schwarz, L., Ducreux, M., and Conroy, T.
