Single-port Robotic Radical Gastrectomy for Gastric Cancer

Efficacy and Safety Assessment of Single-port Robotic Radical Gastrectomy for Gastric Cancer: a Phase 2a Trial Based on the IDEAL Framework

This study is a single-center, phase 2a exploratory clinical study based on IDEAL framework. The intraoperative and postoperative complications were analyzed to evaluate the safety, feasibility and clinical efficacy of single-port robot-assisted gastric tumor resection.

Study Overview

Detailed Description

The study assessed the intraoperative adverse events (device-related and/or procedure-related), postoperative complications, perioperative recovery outcomes, surgical specimen quality, and pathological indices of Single-port robot-assisted radical gastrectomy for gastric cancer.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Intraoperative adverse events and 30-day postoperative complications
Time Frame: Intraoperative and postoperative 30 days
Intraoperative adverse events (device and/or procedure-related). Events were recorded as Preferred Term and classified under System Organ Class as per MedDRA Common Terminology Criteria for Adverse Events (CTCAE) coding guidelines (https://evs.nci.nih.gov/ftp1/CTCAE/About.html). Postoperative complications will refer to any medical occurrence directly attributed to the surgical procedure within the first 30 days.
Intraoperative and postoperative 30 days
Conversion rate
Time Frame: Intraoperative
Conversion to open or laparotomy surgery due to intraoperative complications , technical difficulties, or inability to successfully complete predefined procedural steps .
Intraoperative

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Length of incision
Time Frame: Intraoperative
The total length (in centimeters) of the surgical skin incision made during the procedure, measured immediately after wound closure.
Intraoperative
Intraoperative Blood Loss
Time Frame: Intraoperative
The estimated volume of blood lost during surgery (in milliliters), calculated based on suction collection volume and the weight of used gauze sponges, using standard conversion methods.
Intraoperative
Operative Time
Time Frame: Intraoperative
The duration (in minutes) from the initial skin incision to final wound closure, excluding anesthesia induction and emergence.
Intraoperative
Postoperative Length of Hospital Stay
Time Frame: 7 days after surgery
The number of days between the day of surgery (postoperative day 0) and the day of hospital discharge, inclusive of the discharge day if applicable per institutional protocol.
7 days after surgery
Number of Lymph Nodes Harvested
Time Frame: 7 days after surgery
The total count of lymph nodes removed during the lymphadenectomy and confirmed by pathological examination.
7 days after surgery
