The Use of Wound Protector in Whipple's Procedure With Intrabiliary Stent

Brief Summary:

Background: There are no published studies regarding the use of wound protectors in the context of surgical site infection (SSI) rates among patients receiving a pancreatoduodenectomy (Whipple) with preoperatively placed intrabiliary stents. In high volume experiences, the SSI rate is 40-50% within this cohort. In Calgary, preoperative biliary stent placement for bile duct decompression represents the norm given typical surgical wait times. In addition to having higher associated lengths of hospital stay, ICU admissions, hospital re-admissions, and overall mortality, patients with SSI are also delayed, and often omitted, in their progression to critical oncologic adjuvant chemotherapy. As a result, SSI remain crucial and devastating complications for pancreas surgeons and their patients alike.

Methods: The investigators will complete a randomized controlled trial evaluating the rate of SSI in adult patients who undergo a pancreatoduodenectomy following biliary stent placement when wound protectors are employed versus no wound protector use. This trial will employ block randomization. All four University of Calgary Heapato-Pancreatico-Biliary (HPB) surgeons will participate with a planned inclusion of all patients scheduled to undergo a pancreatoduodenectomy.

Analysis: The investigators will use an intention to treat approach to the analysis. Categorical baseline data will be analyzed using the Fisher exact probability test. Non-categorical baseline data will be analyzed using the Student t test. SSI rates will be determined using the Fisher exact probability test.

Hypothesis: Wound protectors will reduce the SSI rate in patients undergoing a pancreatoduodenectomy with preoperatively placed intrabiliary stents.

Potential Impact: Given the tremendous oncologic, economic, and psychological impact of SSI following pancreatoduodenectomy, the epidemic incidence of this complication must be reduced. The additional crippling effect of refusing (Medicare) payment for any patient who receives a SSI in the United States has launched all techniques and analyses that can potentially reduce this complication into the National health care agenda. In Canada, health care utilization and economics are always a relevant and ever expanding area of importance. It is crucial that the investigators reduce complications such as SSI, regardless of individual payer sources.

Arm Intervention/treatment
Experimental: Alexis group
In experimental group patients, the surgeon will use Alexis - a wound protector during surgery.
Device: Alexis - a wound protector
Alexis is a double ring, self-retaining circumferential device that is designed to protect incision site during surgical manipulation.

No Intervention: Control group
In no intervention group patients, the surgeon will not use any wound protector during surgery.

Primary Outcome Measures :
  1. Surgical Site Infection (SSI) Rate [ Time Frame: 1 month ]
    SSI will be evaluated on a daily basis by residents, the research/clinical fellow and/or Hepato-Pancreatico-Biliary Team by visual inspection of each wound.
