Prunes are a fiber-rich fruit being effective in treating chronic constipation. The aim of this study was to investigate the effect of prune consumption on the incidence of LARS.  \nMethods: A prospective, double-arm, parallel, nonblinded, randomized controlled trial was conducted from September 2019 to March 2021 at a single tertiary center for patients who underwent low anterior resection. Patients randomized to the prune group consumed prune daily for 2 weeks after surgery, while those in the no-prune group did not. The primary outcome was the incidence of major LARS at 3 weeks after surgery.  \nResults: A total of 130 patients were randomized and 118 completed the study (81 men, 37 women), including 55 patients (46.6%) in the prune group and 63 patients (53.4%) in the no-prune group. LARS was confirmed in 15 patients (27.3%) in the prune group and 47 patients (74.6%) in the no-prune group (P \u003C 0.001). The incidence of major LARS was also significantly lower in the prune group (18.2% vs. 61.9%, P \u003C 0.001). Multivariable analysis showed that the level of anastomosis and prune consumption were significantly associated with the incidence of LARS. The prune group had higher emotional scores and lower symptom scores for constipation, sleep disturbance, and loss of appetite in the quality-of-life questionnaire.  \nConclusion: Prune consumption significantly reduced the incidence of LARS and improved quality of life after low anterior resection.  \nTrial registration: CRIS identifier: KCT0006085 (registered on September 1, 2019).  \nKeywords: Rectal neoplasms; Low anterior resection syndrome; Quality of life; Prune; Dried plum  \nReceived: April 24, 2025; Revised: June 24, 2025; Accepted: July 16, 2025  \nCorrespondence to: Yong Beom Cho, MD, PhD  \nDepartment of Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, 81 Irwon-ro, Gangnam-gu, Seoul 06351, Korea [Email: gscyb@skku.edu](Email: gscyb@skku.edu)  \nCo-correspondence to: Yoonah Park, MD  \nDepartment of Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, 81 Irwon-ro, Gangnam-gu, Seoul 06351, Korea [Email: yoonah.park@samsung.com](Email: yoonah.park@samsung.com)  \n 2025 Korean Society of Coloproctology  \nThis is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License ([https://creativecommons.org/licenses/by-nc/4.0/](https://creativecommons.org/licenses/by-nc/4.0/)) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.  \n510 [www.coloproctol.org](www.coloproctol.org)  \nAnn Coloproctol 2025;41(6):510-518  \n\n| Graphical abstract |  |\n| --- | --- |\n| \u003Cbr>Effect of prune consumption on the incidence of low anterior resection syndrome\u003Cbr>: a randomized controlled trial\u003Cbr>Purpose\u003Cbr>To investigate the effect of prune consumption on the incidence of low anterior resection syndrom","cbCaipbQJLDqH5i3","https://ap.wps.com/l/cbCaipbQJLDqH5i3","pdf",872509,"English","# Introduction\n## Purpose and background\n# Methods\n## Trial design and participants\n# Results\n## Incidence of LARS and quality-of-life findings\n# Conclusion\n## Overall impact of prune consumption\n# Trial registration and publication details","[{\"question\":\"What was the purpose of the study on prune consumption and LARS?\",\"answer\":\"The study aimed to investigate whether consuming prunes reduces the incidence of low anterior resection syndrome after low anterior resection surgery.\"},{\"question\":\"How was the randomized controlled trial conducted?\",\"answer\":\"A prospective, double-arm, parallel, nonblinded randomized controlled trial was conducted from September 2019 to March 2021.
