Assessing Effectiveness of Laparoscopic Colorectal Surgical Skills

2014-07-23 21:09:17 | BioPortfolio


The purpose of this study is to improve the investigators understanding of different training methods in laparoscopic colon surgery.


In this study we use an objective evaluation system which deconstructs laparoscopic colectomy into its component steps. Critical components of the procedure as well as overall operative performance can be evaluated. This is applied to surgeons and trainee surgeons attending laparoscopic colorectal training courses using different training models to compare each model and correlate outcomes with each model to pre-course experience. This project is aimed at better educating trainers and getting better information on the validity of new training models for laparoscopic colectomy.

Aims of Project

- To observe and assess surgical technique during laparoscopic colorectal skills training courses using a previously validated tool for formal assessment of surgical technical skills.

- To evaluate technical errors and patterns of error during training at laparoscopic colectomy.

- To determine outcomes and error rates with different training models and correlate these with prior surgical experience.

Number of participants/subjects in research:

Subjects will be recruited in several sites:

- the principal investigators facility at University Hospitals of Cleveland Case Medical Center, where surgeons from outside institutions visit regularly for training courses

- Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Laparoscopic colorectal training courses, where surgeons participate in courses with invited faculty at national meetings (the PI is national Program Director and runs these courses).

- American Society of Colorectal Surgeons (ASCRS) Laparoscopic colorectal training courses, where surgeons participate in courses with invited faculty at national meetings (the PI is national Program Director and runs these courses).

Course attendees will be informed before the start of an appropriate laparoscopic course that the study is being performed. The study will be explained to them in detail and they will be given a copy of the appropriate paperwork to review. Verbal consent will be requested. It will be explained to them that they should feel under no pressure to participate in the study, and that if they do participate that these data are not used for their evaluation. The number of cases of components of cases that they perform will not be related to participation or non-participation in the trial.

Study Design This is an observational study in which trainees' technical surgical skills are evaluated while performing specific steps of laparoscopic colectomy cases, as outlined in the accompanying datasheets. The plan is to enroll 200 participants.

At the completion of each case, forms will be completed by the trainee, and by the teaching / supervising surgeon. Independent observers cannot be used, as only an attending laparoscopic colorectal surgeon is adequately skilled to score the resident performing the case, and it is not feasible to have a second attending surgeon present during each case.

Dr Delaney will score trainees when possible using the standardized form. For courses at UHCMC, the colorectal faculty will be instructed in standardized assessment, and will also assess trainees. For courses at SAGES or ASCRS, the course faculty will be shown the training assessments and directed in the standardized assessment prior to evaluations.

Medical and Biotech [MESH] Definitions

Excision of a portion of the colon or of the whole colon. (Dorland, 28th ed)

Excision of the gallbladder through an abdominal incision using a laparoscope.

Placement of one of the surgeon's gloved hands into the ABDOMINAL CAVITY to perform manual manipulations that facilitate the laparoscopic procedures.

Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.

Excision, in part or whole, of an intervertebral disk. The most common indication is disk displacement or herniation. In addition to standard surgical removal, it can be performed by percutaneous diskectomy (DISKECTOMY, PERCUTANEOUS) or by laparoscopic diskectomy, the former being the more common.
