# A Case of Lateral Lymph Node Dissection for Recurrence of Rectal Cancer with Senhance Surgical System

## TL;DR

This paper reports the first use of the Senhance Surgical System for lymph node dissection in a recurrent rectal cancer case.

## Contribution

The first reported case of lateral lymph node dissection for rectal cancer recurrence using the Senhance Surgical System.

## Key findings

- The Senhance Surgical System was successfully used for right lateral lymph node dissection.
- The procedure had minimal blood loss and no intraoperative complications.
- Histopathology confirmed metastasis from rectal cancer.

## Abstract

We have performed approximately 200 colorectal cancer surgeries using Senhance Surgical System in our department and we have standardized the surgical procedure with Senhance. For the first time, we report the case of lateral lymph node dissection for recurrence of rectal cancer with Senhance Surgical System.

The patient was a 64-year-old female who was diagnosed with lateral lymph node recurrence of rectal cancer. We performed right lateral lymph node dissection with Senhance Surgical System. The operation time was 175 min and blood loss was 5 mL, with no intraoperative complications. The final histopathologic diagnosis was metastasis of rectal cancer.

We present the first lateral lymph node dissection performed using the Senhance Surgical System. We will accumulate more cases and study its usefulness in the future.
