Learning Curve of Robotic Pancreatoduodenectomy

October 19, 2023 updated by: Peking Union Medical College Hospital

Learning Curve of Robotic Pancreatoduodenectomy for Surgeons With Extensive Laparoscopic Pancreatoduodenectomy Experience

A few reports were focused on the RPD learning curve for surgeons with extensive experience in LPD. Therefore, this study aimed to investigate the number of cases required for such surgeons to overcome the learning curve for RPD and to analyze the impact of different phases of the learning curve on perioperative outcomes.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

With the development of robotic surgery systems, their unique advantages over traditional laparoscopic surgery systems, such as a three-dimensional 10-fold magnified view, seven degrees of freedom for flexible wrist movements, tremor filtering, and good ergonomic design, have significantly improved the precision and quality of surgery. The literature has reported that, compared with the laparoscopic surgery system, the robotic surgery system can reduce intraoperative blood loss and the conversion rate to laparotomy, in addition to the dissection of more lymph nodes. Therefore, robotic surgery has become increasingly popular. As the economy develops and surgeons gain more experience in LPD, many are shifting their focus to robotic pancreatoduodenectomy after mastering laparoscopic techniques. There are a few reports on the RPD learning curve for surgeons with extensive experience in LPD. Therefore, this study aimed to investigate the number of cases required for such surgeons to overcome the learning curve for RPD and to analyze the impact of different phases of the learning curve on perioperative outcomes.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
