Study Overview

Optimal Perioperative Pain Control in Minimally Invasive Abdominal Cancer Surgery

This is a research study to evaluate the effectiveness of 3 different types of routine pain management regimens used during clinically indicated, minimally invasive oncologic (cancer) surgery. This project is considered "Research" and participation is voluntary. Upon enrollment in this study, the research team will collect data from the patient's medical records. The patient will undergo all of the normal testing and procedures required pre-operatively (standard of care). The study team will then randomly assign the patient (like a flip of a coin) to one of three different study arms for pain management during surgery: 1. Laparoscopic Transversus Abdominis Plane Block (LapTAP) with Local Anesthetic (LA) 2. Laparoscopic Transversus Abdominis Plane Block (LapTAP) only 3. Local Anesthetic (LA) only The patient will receive standard pre- and post-operative care according to clinical guidelines (routine care). The study team will collect information from the patient's medical record for the first 24 hours after their surgery and upon discharge. This information will include pain scores, amount of medication required, any side effects the patient may have experienced, and satisfaction with pain control. Participation in the study will end upon discharge from the hospital.

Traditional pain management strategies have heavily relied on the use of Local Anesthesia (LA). Laparoscopic Transversus Abdominis Plane block (LapTAP) has emerged as a new approach for postoperative pain control following minimally invasive surgery, promising enhanced pain control in comparison with traditional approaches. Preliminary investigations into LapTAP have shown promise, yet there remains a significant gap in comparative effectiveness research, especially juxtaposed against the more traditional LA. We propose a comprehensive three-arm superiority trial evaluating LapTAP in conjunction with LA, LapTAP alone, and LA alone. We intend to scrutinize the efficacy of each modality in managing postoperative pain specific to minimally invasive oncologic surgery. Findings from this trial will be used to refine clinical protocols, improve patient outcomes, and potentially standardize care in postoperative pain management for minimally invasive oncologic procedures.

Arms and Interventions

Participant Group/ArmIntervention/Treatment
ACTIVE_COMPARATOR: Laparoscopic Transversus Abdominis Plane Block with Local Anesthetic

Patient would be receiving Laparoscopic Transversus Abdominis Plane block in addition to Local Anesthetic per standard of care.

PROCEDURE: Local Anesthesia

  • For local anesthetic administration at port sites, 30 mL of 0.1% ropivacaine is injected around the umbilical port site following the completion of the primary surgical procedure. Additionally, 5 mL of 0.1% ropivacaine is injected around each additional p

PROCEDURE: Laparoscopic Transversus Abdominis Plane block

  • Surgeon will place 18 gauge needle into the fascial plane between the internal oblique and transversus abdominis muscles. Once the needle is accurately positioned surgeon will inject 15 mL of 0.1% ropivacaine slowly. This procedure is performed bilaterall
ACTIVE_COMPARATOR: Laparoscopic Transversus Abdominis Plane block only

Patient would be receiving Laparoscopic Transversus Abdominis Plane block without Local Anesthetic per standard of care.

Primary Outcome MeasuresMeasure DescriptionTime Frame
Pain ScorePain will be measured in the post anesthesia care unit (PACU) using Visual Analog Scale. Pain will be scored from zero to ten, with zero being no pain at all and ten being unbearable pain.Hourly, starting 1 hour post surgery for 24 hours, then at time of hospital discharge (on average 1 week)
Secondary Outcome MeasuresMeasure DescriptionTime Frame
Opioid ConsumptionOpioid consumption (milligrams) within the first 24 hours post-surgery (standardize with Morphine equivalence).up to 24 hours post surgery
Recovery Analgesic TimeTime to first rescue analgesic requestup to 24 hours post surgery
Adverse Event(s) FrequencyFrequency of any adverse events related to interventionsimmediately post surgery up through discharge (on average of 1 week)
Adverse Event(s) SeveritySeverity of any adverse events related to interventionsimmediately post surgery up through discharge (on average of 1 week)
Patient Satisfaction with Pain ManagementWill gauge patient perceptions of pain control and overall satisfaction with their treatment with a standardized Visual Analog Scale utilizing a zero to ten scale, with zero being completely dissatisfied and ten being completely satisfied.At discharge (on average of 1 week)
