The purpose of this study is to evaluate the use of a D-dimer based protocol to screen for thrombotic events in colorectal surgical patients. This study is unique because of the multistage screening process for DVT's using a standardized D-dimer testing methodology and ultrasound that will take place throughout the preoperative, perioperative, and postoperative processes. The data collected from this screening study will help establish the baseline DVT rates in UTMB's colorectal surgical patients before and after surgery. Additionally, the data from this study can help determine if a D-dimer blood test has predictive value in UTMB's colorectal surgical patient population. This study may also provide preliminary evidence for further research regarding the adjustment of D-dimer cutoff values. Specifically for patient subsets such as surgical colorectal patients with a moderate pretest probability and clinical conditions associated with low test specificity

Observe the point prevalence of DVT's in preoperative colorectal patients at UTMB prior to having colorectal surgery.
Timeframe: 1 year
Determine the incidence of postoperative DVT that occurred during the first 2 days of the inpatient stay that was discovered by a lower limb venous duplex
Timeframe: 1 year
Compare the number of DVT events in postoperative hospitalized patients that were on the D-dimer monitoring protocol.
Timeframe: 1 year
Determine if there is a statistical difference between the D-dimer value of patients with DVT prior to surgery compared to patients who develop DVT after surgery
Timeframe: 1 year
Compare the D-dimer results of DVT positive subjects to DVT negative subjects to identify a specific result range seen in the DVT positive subjects.
Timeframe: 1 year
