Summary
A mechanical bowel preparation using 2 liters of polyethylene glycol (PEG) solution with a laxative demonstrated similar patient acceptability and efficacy compared to 4 liters of PEG solution for colorectal surgery. This regimen also showed a trend towards fewer septic complications.
Area of Science:
- Colorectal Surgery
- Gastroenterology
- Surgical Preparation
Background:
- Effective bowel preparation is crucial for elective colorectal resections.
- Traditional bowel cleansing regimens can be associated with poor patient tolerance and discomfort.
- Optimizing bowel preparation protocols aims to improve patient outcomes and reduce complications.
Purpose of the Study:
- To compare the acceptability and efficacy of a reduced-volume mechanical bowel preparation (2 liters PEG plus laxative) versus a standard-volume preparation (4 liters PEG).
- To assess patient-reported outcomes including nausea, vomiting, and abdominal discomfort.
- To evaluate the intraoperative efficacy of bowel lavage and the incidence of septic complications.
Main Methods:
- A prospective, randomized study included 100 patients undergoing elective colorectal resection.
- Patient acceptability was measured using visual analog scales for nausea, vomiting, cramps, and discomfort.
- Bowel preparation efficacy was assessed intraoperatively by a blinded surgeon.
Main Results:
- No significant difference in overall acceptability was observed between the 2-liter (5.1 +/- 2.8) and 4-liter (5.6 +/- 2.6) PEG groups (P = 0.5).
- Incidence and severity of nausea, vomiting, anal discomfort, and cramps were comparable between groups.
- Excellent bowel preparation efficacy was achieved in 94% of the 2-liter group versus 84% of the 4-liter group (P = 0.5), with a trend towards fewer septic complications in the 2-liter group (2% vs 12%, P = 0.06).
Conclusions:
- A 2-liter polyethylene glycol (PEG) solution combined with a laxative offers comparable acceptability and efficacy to a 4-liter PEG regimen for mechanical bowel preparation.
- The reduced fluid volume in the 2-liter PEG regimen is advantageous, potentially avoiding the need for nasogastric tube insertion.
- This optimized bowel preparation strategy should be considered for elective colorectal surgery to enhance patient comfort and potentially reduce septic complications.
