What can result from an anastomosis in Low Anterior Resection (LAR) under tension?

The correct response regarding what can result from an anastomosis in Low Anterior Resection (LAR) under tension is linked to the anatomical and physiological impacts of surgical maneuvering.

In the context of LAR, the tension on the anastomosis can lead to complications such as decreased blood flow to the joined segments of the bowel. This reduced blood supply can compromise healing and function, ultimately leading to a loss of reservoir function in the newly formed pouch or anastomosis. As a result, patients may experience fecal urgency due to the impaired ability of the bowel to properly store fecal matter. This loss of reservoir capability is significant because it alters a patient’s bowel habits and can severely affect their quality of life.

The other choices reflect potential complications related to surgery in general, but they do not directly address the specific consequence of tension on an anastomosis in LAR. For instance, while an increased risk of infection is a general risk in any surgical procedure, it is not the primary outcome of tension on an anastomosis specifically in LAR. The distractions of increased absorption and adhesion formation are less direct consequences of tension related to anastomotic integrity and function after such a resection.
