Many surgeries have been postponed due to Covid. But your patients can be reassured: delays in stoma reversal surgery do not affect long-term outcomes. However, you shouldn’t wait too long.
Stoma reversal aims to reverse a colostomy in, for example, patients recovering from bowel cancer. But post-surgical complications, such as loss of bowel function or inflammation, are common. A Lancaster University study, led by Dr. Rachael Rigby from the Faculty of Health and Medicine, now aims to improve outcomes of patients in those which have undergone this relatively common type of surgery.
Rigby led a team which examined historic tissue samples from part of the colon which would normally be discarded during stoma reversal surgery as well as examining the bacteria living within the bowel. She said: “We gained pilot data from historic tissue samples and obtained funding from Bowel Cancer Research and North West Cancer Research enabling us to fund students to analyze additional tissue samples and commensal microbiota, bacteria which reside within the bowel.” In 2017, the team already published research showing that commensal microbiota are depleted in the defunctioned bowel.
Feedback from patients shows that their main concern was whether a delay in reversal surgery, particularly following the pandemic, would increase the likelihood of developing complications. Rigby said: “This follow-up study is the first to show that delaying stoma reversal surgery does not impact on risk of complications or commensal microflora loss, atrophy or scarring. However, a higher degree of microflora loss is associated with an increased risk of complications. This loss appears to be related to the overall number of bacteria present, rather than the loss of specific types of bacteria. This is of great importance to finding ways to reduce post-surgical complications in patients.”
Researchers are currently trying to test whether feeding the commensal microflora through the stoma prior to surgery can increase numbers and improve the outcomes of reversal surgery.
