Three-dimensional (3D) printing offers patient-specific anatomical models that can enhance surgical planning. Its application in diverticular disease remains underexplored. Case Presentation: We present the case of a 65-year-old male with recurrent diverticulitis involving the sigmoid and descending colon. After conservative management of an acute episode, preoperative imaging revealed extensive diverticulosis. A patient-specific 3D-printed model was created from CT images to plan the surgical approach. The model helped determine the need for a left hemicolectomy rather than a simple sigmoidectomy, anticipated technical challenges such as lowering the left colic flexure and ligating the inferior mesenteric artery, and improved patient counseling. The surgery was performed laparoscopically without complications, and the patient was discharged on postoperative day six. Histology confirmed diverticulosis with perivisceritis and reactive lymphadenitis. Conclusions: This case demonstrates the potential of 3D printing to optimize surgical planning in diverticular disease, enabling tailored resections and improving operative strategy. Broader adoption may be limited by time and cost but offers clear educational and clinical benefits.<\/jats:p>","DOI":"10.3390\/reports8040222","type":"journal-article","created":{"date-parts":[[2025,11,3]],"date-time":"2025-11-03T13:55:22Z","timestamp":1762178122000},"page":"222","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["3D-Printed Model for Surgical Planning in Diverticular Disease: A Case Report"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6691-0881","authenticated-orcid":false,"given":"Alessandro","family":"Gemini","sequence":"first","affiliation":[{"name":"Department of Digestive and Emergency Surgery, \u201cS.
