Robotic Subtotal Colectomy with en-bloc Resection of the Left Chest wall for Locally Advanced Colonic Cancer: A Case Report and Literature Review

Introduction: locally advanced colonic cancers requiring multivisceral en-bloc resections are typically undertaken in an open or laparoscopic approach. case presentation: here, we report a case of a complex robotic subtotal colectomy with en-bloc resection of the chest wall and left 10th to 12th ribs for management of a locally advanced descending colon cancer and peritumoral abscess at our institution in june 2020. the procedure included intraoperative ultrasound scanguided marking to delineate the tumoral extent. histologically, negative excision margins (r0) were achieved. we also briefly reviewed the relevant literature. there are very few publications on multivisceral resections for advanced colonic cancer; this is the second reported case of robotic en-bloc colonic resection in english literature. a similar case report published in 2019 enforced the value of multidisciplinary collaboration and the benefits of robotic over laparoscopic surgery in en-bloc resections. conclusion: considering the improved short-term outcomes and comparable oncological safety granted by laparoscopic surgery, minimally-invasive surgery has a clear role in the surgical management of locallyadvanced colorectal cancers.
