Robotic-Assisted Ascending Hemicolectomy for Colon Cancer in a Patient With Situs Inversus Totalis: A Case Report.

We present a case of robotic-assisted ascending hemicolectomy in an 82-year-old woman with situs inversus totalis. The patient underwent a screening colonoscopy, during which a polypoid lesion in the ascending colon was discovered. Biopsy results revealed a tubular adenoma with high-grade dysplasia. An ascending hemicolectomy with radical lymphadenectomy was subsequently performed, leading to a final diagnosis of a tubulovillous adenoma with focal intramucosal carcinoma, negative for metastatic disease. The challenges related to instrument handling during surgery in patients with situs inversus totalis can be mitigated by using a robotic approach, which preserves the efficiency of laparoscopic techniques. This report highlights the importance of robotic surgery in managing complex procedures in patients with anatomical variations or other technical challenges.
