We report two cases occurring during robotic colorectal resection performed in 25-degree Trendelenburg with 12\u00a0mmHg pneumoperitoneum. A 74\u00a0year old woman undergoing robotic sigmoid resection developed left sided otorrhagia intraoperatively, with computed tomography and otolaryngologic examination demonstrating blood in the external auditory canal and tympanic membrane injury. A 63\u00a0year old man undergoing robotic low anterior resection developed bilateral otorrhagia during emergence from anesthesia. Both patients were managed conservatively with otolaryngologic follow-up and recovered without ongoing bleeding or subjective hearing impairment. Previously reported cases have been described mainly in urologic and gynecologic surgery, usually under steeper Trendelenburg conditions. These cases show that perioperative otorrhagia may also occur during robotic colorectal surgery under moderate positioning parameters and is usually associated with a favorable outcome.<\/jats:p>","DOI":"10.1093\/jscr\/rjag404","type":"journal-article","created":{"date-parts":[[2026,5,7]],"date-time":"2026-05-07T11:43:09Z","timestamp":1778154189000},"source":"Crossref","is-referenced-by-count":0,"title":["Otorrhagia during robotic colorectal resection: a two case series and review of the literature"],"prefix":"10.1093","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-8080-3001","authenticated-orcid":false,"given":"Micha\u0142","family":"Kazanowski","sequence":"first","affiliation":[{"name":"Department of Surgical Oncology, Lower Silesian Center of Oncology, Pulmonology and Hematology , Wroclaw ,","place":["Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pawe\u0142","family":"Lesiak","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology, Lower Silesian Center of Oncology, Pulmonology and Hematology , Wroclaw ,","place":["Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bartosz","family":"Kapturkiewicz","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology, Lower Silesian Center of Oncology, Pulmonology and Hematology , Wroclaw ,","place":["Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u0119drzej","family":"Wierzbicki","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology, Lower Silesian Center of Oncology, Pulmonology and Hematology , Wroclaw ,","place":["Poland"]},{"name":"Laboratory of Immunopathology, Department of Experimental Therapy, Hirszfeld Institute of Immunology & Experimental Therapy; Polish Academy of Sciences , Wroclaw ,","place":["Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pawe\u0142","family":"Maciejewski","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology, Lower Silesian Center of Oncology, Pulmonology and Hematology , Wroclaw ,","place":["Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marek","family":"B\u0119benek","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology, Lower Silesian Center of Oncology, Pulmonology and Hematology , Wroclaw ,","place":["Poland"]},{"name":"Faculty of Medicine, Wroclaw University of Science and Technology , Wroclaw ,","place":["Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,5,27]]},"reference":[{"key":"2026052706562208800_ref1","doi-asserted-by":"publisher","first-page":"549","DOI":"10.1016\/S0750-7658(01)00420-8","article-title":"L\u2019otorragie postop\u00e9ratoire\u00a0: Une complication m\u00e9connue de la position de Trendelenburg en chirurgie c\u0153lioscopique\u00a0?","volume":"20","author":"Aunac","year":"2001","journal-title":"Ann Fr Anesth R\u00e9animation"},{"key":"2026052706562208800_ref2","doi-asserted-by":"publisher","first-page":"bcr2014206118","DOI":"10.1136\/bcr-2014-206118","article-title":"Bilateral otorrhagia: a rare complication of laparoscopic abdominopelvic surgery","volume":"2014","author":"Addison","year":"2014","journal-title":"BMJ Case Rep"},{"key":"2026052706562208800_ref3","doi-asserted-by":"publisher","first-page":"1229","DOI":"10.1016\/j.jmig.2017.04.009","article-title":"Bilateral otorrhagia after robotically assisted gynecologic surgery in the setting of a reduced Trendelenburg position and low-pressure pneumoperitoneum: a case report and review of the literature","volume":"24","author":"Aloisi","year":"2017","journal-title":"J Minim Invasive Gynecol"},{"key":"2026052706562208800_ref4","doi-asserted-by":"publisher","first-page":"101151","DOI":"10.1016\/j.gore.2023.101151","article-title":"Robotic-assisted gynecologic surgery associated tympanic membrane perforation: a report of two cases and review of the literature.
