What is Laparoscopic Surgery?
Laparoscopic surgery: performed through tiny holes made in the body; surgeon has limited view
of the operating site
Open surgery: the surgeon makes a long
incision and has a clear view of the operating site
Success depends on optimal exposure of the operating site
The Laparoscopic Challenges
Limited view of the operating field Rigid retractors may cause organ damage Tilting the surgical table may cause post-operative
complications
Existing retracting techniques are inefficient
Titling the surgical table to improve visual field
Retractors to push aside the organs
LapSpace: Safe Retraction for Optimal View
Improved visibility No organ damage Reduced complications Shortened procedure time Reduced hospital costs

"During some of the thousands of laparoscopic procedures I performed, I would have given anything for an extra hand inside the abdomen for retraction. The LapSpace retractor meets that
need.Dr. David Earle, Baystate Medical Center

I spend 15% of my time clearing the view. I would use LapSpace in about 80% of my cases.

FUTURE RESEARCH Transition to an analytic RCT study in
order to corroborate initial findings and provide launching points for further studies
Further investigation into how this device can improve on efficacy, time, and costs of laparoscopic operations
BACKGROUNDSuccess of any laparoscopic surgery relies on optimalexposure of the operative site. In operations, surgeonsand assistants are required to tightly strap the patientson the surgical bed but must continuously change thepatients position and manipulate bowels usinggraspers to keep organs from obstructing view of thesite. Smaller bowels and organs, however, are not ableto be held back efficiently using these techniques andslide continuously into the operating area. Currently,maneuvers such as the Trendelenburg as well asmetallic instruments are used to clear abdominalorgans from the operating field, but are only partiallyeffective and can cause unintentional trauma to thepatient. Therefore, it is of importance in laparoscopicsurgeries that instruments must optimally reveal thesurgical site while ensuring that the surroundingbowels and organs are kept away safely in place.
TESTING & RESULTS
A NOVEL INFLATABLE AND RETRACTING LAPAROSCOPIC DEVICE THAT PROVIDES MAXIMAL EXPOSURE OF THE OPERATIVE FIELD Ambar Mehta1, Anirudh Dwarakanath MS2, Rohith M Bhethanabotla3, Hien T Nguyen MD1,2,

LAPSPACEThe LapSpace laparoscopic retractor is placed through a 10-mm trocar and controls an inflatable balloon at its tip. Once the device is inside the abdomen, the surgeon inflates the balloon and surgeons can control its positioning and retraction angle. A bed clamp provides permanent retraction and hands-free utilization. The balloon itself is a biocompatible polymer, made of nylon fibers and thermoplastic polyurethane, which is atraumatic to tissue and can hold sufficient tension and pressure. The retractor minimizes mobilization of the small intestines and stabilizes the abdominal organs.
OBJECTIVESTo evaluate the safety and feasibility ofLapSpace, an innovative, FDA-approved,laparoscopic device with an inflatable elementthat can retract abdominal contents forcreating and maintaining optimal exposure ofthe operative field.
STUDY METHODSSample Size: The study contained 20 patients over 1 year.Conditions for Study: Patient participants were informed that we are using a novel device in their operation. Those who did not wish to give consent were not enrolled in the study. Also, any evidence of safety or inefficiency during the operation terminated its use.Post-Surgical Evaluation: Operative time and surgeon feedback were evaluated with a LapSpace-designed post-surgical survey, which compared operations performed with and without LapSpace.
CONCLUSIONThe LapSpace inflatable retractor, with itsnovel inflatable component and manually-controlled retractor, has initiallydemonstrated versatility in a wide varietyof operations, in providing an optimaloperating field, and in reducing inadvertenttissue injuries. It has also received strongapproval by the surgeons using theinstrument in comparison to the statusquo. Due to the utility of this device, thereis potential for it to become commonlyused in many different types of minimallyinvasive procedures.
LIMITATIONS Study was a descriptive survey-based
study that was intended to assess feasibility and safety
Further quantitative studies will be needed to determine superiority over prior art
Greater sample size necessary and a more elaborate measure to model inter-rater reliability

A 15-question survey collected the surgeons feedback on the devices safety, utility, ergonomics, and satisfaction. The surgeons overwhelmingly stated that this device provides optimal exposure of the operating field, minimizes risks of inadvertent tissue injuries, and reduces the tilt or the time spent by the patient in the Trendelenburg position. Each surgeon was satisfied with the ergonomics of the handle and noted that they would use the device again. Only one surgeon experienced minor difficulties with deflating the balloon completely.

Success of any laparoscopic surgery relies on optimal exposure of the operative site. In operations, surgeons and assistants are required to tightly strap the patients on the surgical bed but must continuously change the patients position and manipulate bowels using graspers to keep organs from obstructing view of the site.

Currently, maneuvers such as the Trendelenburg as well as metallic instruments are used to clear abdominal organs from the operating field, but are only partially effective and can cause unintentional trauma to the patient.

*Do we have any more data that needs to be added?
*Not sure what else to put under Future Research
*I know its not very pretty. Want to get the content right before making aesthetic changes
