Abstract
Postoperative complications after colorectal resections including injuries to the bowel and genitourinary structures, pelvic hemorrhage, small bowel obstruction, surgical site infections, abscesses, and anastomotic leaks, strictures, and bleeding.
Previous studies have indicated that an immediate anastomosis in the absence of intraoperative mechanical bowel preparation is associated with a high anastomotic leak rate.
Infectious complications after colorectal resections are some of the most severe postoperative complications, leading to an increase in mortality, morbidity, hospital cost, and length of hospitalization. Infectious complications, with a 40% incidence rate, were one of the main causes of mortality and morbidity in patients undergoing colorectal surgery in the first half of the 20th century.
Mechanical and oral antibiotic bowel preparations have been used by surgeons for decades in an attempt to decrease postoperative infectious complications. However, during the last 2 decades, there has been growing controversy regarding the effects of mechanical bowel preparation (MBP) on postoperative infectious complications.
Mechanical bowel preparation (MBP) before colorectal resection is questionable and controversial in the modern perioperative care of colorectal patients.
The aim of this study was to evaluate the safety of colectomy without mechanical bowel preparation in elective abdominal colorectal operations.
Thirty abdominal colorectal procedures were performed during the study period. fifteen of these patients did not undergo MBP (NMBP). The remaining 15 cases submitted to MBP. Comparison between both groups was done for different risk factors and outcomes to assess the safety and value of MBP before colectomy, and results were analyzed
The major finding of this study was that left-sided colon cancer surgery could be performed safely without MBP and MBP doesn’t improve the short-term outcome after colonic resection. This result is consistent with the findings of previous studies, and brings the common use of MBP before elective open colonic resection into question. However, recent surveys indicate that the current body of evidence has had little influence on surgical practice.
