Time to readiness for RIOT (return to intended oncologic therapy) |
Will be tabulated with frequency and percentages. Will be compared using chi-square test with Fisher's correction as indicated. To assess the relationship between study variables and time to event outcomes (such as RIOT), Kaplan-Meier plots and log-rank tests will be used. |
Up to 5 years |

Other |
Narcotic utilization |
Will be summarized using descriptive statistics including mean, standard deviation, median and range. Will be compared with 2-sample t- tests, Mann Whitney U tests or Wilcoxon rank sum tests as indicated. |
Up to 5 years |

Other |
Compliance with ordering and delivery of Enhanced Recovery After Surgery program elements |
Will be tabulated with frequency and percentages. Will be compared using chi-square test with Fisher's correction as indicated. |
Up to 5 years |

Other |
Cost of perioperative care |
Will be summarized using descriptive statistics including mean, standard deviation, median and range. Will be compared with 2-sample t- tests, Mann Whitney U tests or Wilcoxon rank sum tests as indicated. |
Up to 5 years |

Other |
Biologic inflammatory markers |
Will be summarized using descriptive statistics including mean, standard deviation, median and range. Will be compared with 2-sample t- tests, Mann Whitney U tests or Wilcoxon rank sum tests as indicated. |
Up to 5 years |

Primary |
Total length of inpatient stay |
Will be recorded and compared between groups. Will be summarized using descriptive statistics including mean, standard deviation, median and range. Will be compared with 2-sample t- tests, Mann Whitney U tests or Wilcoxon rank sum tests as indicated. |
Up to 5 years |
|
Secondary |
Early post-operative pain control |
The area under the curve for each patient will be computed using the trapezoidal method using the pain score by time curve as has been done in prior studies of this type at MD Anderson. Will be compared between groups. In addition, the number of patients experiencing severe pain (>= 7/10) during the inpatient recovery period will be compared between study groups. Will be summarized using descriptive statistics including mean, standard deviation, median and range. Will be compared with 2-sample t- tests, Mann Whitney U tests or Wilcoxon rank sum tests as indicated. |
Within 48 hours post surgery |

Secondary |
Complication rates secondary to the analgesic regimen |
Pain control modality complications will be prospectively recorded including epidural hematoma, epidural catheter migration/malfunction, injection/exit site cellulitis, epidural abscess, cerebrospinal fluid leak, prolonged ileus (defined as inability to tolerate regular diet by post operation day 5), imbalance and gait instability, altered mental status and delirium, and need to change pain control modality due to inadequate pain control. The rate of these complications will be compared between study groups. Will be tabulated with frequency and percentages. Will be compared using chi-square test with Fisher's correction as indicated. |
Up to 5 years |
|
Secondary |
Surgical complication rates |
Postoperative surgical complications will be prospectively recorded and graded using the Accordian grading scale. Liver surgery specific complications including bile fistula, bleeding requiring transfusion and liver failure will be recorded. 30-day readmission and 90-day mortality will be recorded. The rates of these complications will be compared between study groups. Will be tabulated with frequency and percentages. Will be compared using chi-square test with Fisher's correction as indicated. |
Up to 5 years |
|
Secondary |
Measures of functional recovery |
Quality of recovery will be assessed using the MD Anderson Symptom Inventory for gastrointestinal cancer (MDASI-GI) at regimented intervals including preoperative baseline and postoperative inpatient and outpatient recovery, Return to baseline symptoms including return to baseline life interference summary score at 6 weeks postoperatively, measured using the MDASI-GI, will be compared between groups. Likewise, pre- and post-operative physical and cognitive performance recovery will be compared between groups. Will be summarized using descriptive statistics including mean, standard deviation, median and range. Will be compared with 2-sample t- tests, Mann Whitney U tests or Wilcoxon rank sum tests as indicated. |
