Moreover, ischemic complications should be considered when performing pancreatoduodenectomy in patients with celiac axis and superior mesenteric artery (SMA) stenosis. However, whether these surgical procedures can be safely performed remains unclear.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Case presentation<\/jats:title>\n                <jats:p>A 75-year-old man had a history of laparoscopic proximal gastrectomy (PG) with double-flap technique for gastric cancer and laparoscopic sigmoidectomy for sigmoid cancer treated 4\u00a0years ago. Follow-up computed tomography (CT) revealed an irregular nodular tumor measuring 13\u00a0mm in the pancreatic head. The patient was diagnosed with resectable pancreatic head cancer without lymph node metastasis (cT1cN0M0, cStageIA) according to the Union for International Cancer Control, 8th edition. As a standard pancreatic cancer treatment, two courses of preoperative chemotherapy with gemcitabine plus S-1 were administered. CT after preoperative chemotherapy identified no significant changes in tumor size but revealed SMA stenosis due to atherosclerosis. Blood flow to the left-sided colon was supplied from the middle colic artery via the SMA because of the past sigmoidectomy with inferior mesenteric artery detachment. Therefore, SMA stent placement was performed 1\u00a0day preoperatively. Subsequently, pylorus-preserving pancreatoduodenectomy (PPPD) was performed, preserving the remnant stomach with the right gastroepiploic (RGE) artery and vein. After resection, indocyanine green fluorescence imaging confirmed a good blood supply to the remnant stomach. The operation time was 467\u00a0min, and the blood lost was 442\u00a0mL. Histopathologically, the tumor was diagnosed as moderate adenocarcinoma and pT1cN0M0, Stage IA. The postoperative course was uneventful. The patient was discharged on postoperative day 23. S-1 as adjuvant chemotherapy was administered on postoperative day 63. The patient has been alive without recurrence for 7\u00a0months.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>We performed PPPD preserving blood supply for pancreatic head cancer in a patient with benign SMA stenosis and a history of PG and sigmoidectomy. Blood supply was preserved through preoperative SMA stent placement and a surgical procedure preserving the RGE vessels. Furthermore, S-1 adjuvant chemotherapy was successfully initiated. These multimodal therapies contributed to a favorable clinical outcome.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s40792-024-02063-w","type":"journal-article","created":{"date-parts":[[2024,11,21]],"date-time":"2024-11-21T07:05:07Z","timestamp":1732172707000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Pylorus-preserving pancreatoduodenectomy preserving blood supply for pancreatic cancer with a history of proximal gastrectomy and sigmoidectomy: a case report"],"prefix":"10.1186","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-7640-1770","authenticated-orcid":false,"given":"Yuto","family":"Nakane","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takayuki","family":"Minami","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasuhiro","family":"Kurumiya","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keisuke","family":"Mizuno","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ei","family":"Sekoguchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gen","family":"Sugawara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaya","family":"Inoue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takehiro","family":"Kato","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naohiro","family":"Akita","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,11,21]]},"reference":[{"key":"2063_CR1","doi-asserted-by":"publisher","first-page":"430","DOI":"10.1007\/s00268-012-1860-1","volume":"37","author":"H Takahashi","year":"2013","unstructured":"Takahashi H, Nara S, Ohigashi H, Sakamoto Y, Gotoh K, Esaki M, et al.
