This report describes the detailed technique and key considerations for longitudinal pancreaticojejunostomy (LPJ) as a reconstructive method following pancreaticoduodenectomy (PD) in patients with CP. This approach aims to achieve wide\u2010area drainage of the remnant pancreatic duct through a side\u2010to\u2010side anastomosis between the extensively opened pancreatic duct and jejunum. Conceptually derived from conventional drainage procedures such as the Frey and Partington procedures, this technique is particularly beneficial when significant ductal dilatation persists distal to the resection margin. Critical steps for successful LPJ include meticulous exposure of the pancreatic parenchyma, an adequate longitudinal incision of the main pancreatic duct, and precise anastomotic technique. We have successfully applied this procedure in three male patients (median age 68\u2009years, range: 48\u201377), including one with CP complicated by duodenal bleeding and two with pancreatic head region malignancies complicated with CP. All patients had favorable postoperative outcomes with no clinically relevant postoperative pancreatic fistula (Grade B or C). Long\u2010term follow\u2010up showed significant symptom improvement without medication, and pancreatic function were relatively well preserved. Our preliminary experience suggests that LPJ provides safe and effective drainage of the pancreas following PD in patients with CP\u2010complicated pancreatic head pathology and may represent a valuable reconstructive option, particularly in cases with marked pancreatic duct dilatation.<\/jats:p>","DOI":"10.1002\/ags3.70098","type":"journal-article","created":{"date-parts":[[2025,10,21]],"date-time":"2025-10-21T04:49:09Z","timestamp":1761022149000},"page":"281-286","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Longitudinal Pancreaticojejunostomy Reconstruction Following Pancreaticoduodenectomy for Patients With Concomitant Chronic Pancreatitis: How I Do It"],"prefix":"10.1002","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-9688-4956","authenticated-orcid":false,"given":"Hideaki","family":"Sato","sequence":"first","affiliation":[{"name":"Department of Surgery Tohoku University Graduate School of Medicine  Sendai Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaharu","family":"Ishida","sequence":"additional","affiliation":[{"name":"Department of Surgery Tohoku University Graduate School of Medicine  Sendai Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoki","family":"Rikiyama","sequence":"additional","affiliation":[{"name":"Department of Surgery Tohoku University Graduate School of Medicine  Sendai Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6436-5477","authenticated-orcid":false,"given":"Masamichi","family":"Mizuma","sequence":"additional","affiliation":[{"name":"Department of Surgery Tohoku University Graduate School of Medicine  Sendai Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michiaki","family":"Unno","sequence":"additional","affiliation":[{"name":"Department of Surgery Tohoku University Graduate School of Medicine  Sendai Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,10,20]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00535-022-01911-6"},{"key":"e_1_2_11_3_1","first-page":"898","article-title":"Retrograde Surgical Drainage of the Pancreas for Chronic Relapsing Pancreatitis","volume":"69","author":"Puestow C.
