Overview
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:
- Laparoscopic Transversus Abdominis Plane Block (LapTAP) with Local Anesthetic (LA)
- Laparoscopic Transversus Abdominis Plane Block (LapTAP) only
- 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.
Description
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.
