Hypothesis
What are the factors contributing to the development of Low Anterior Resection Syndrome (LARS) in patients after rectal cancer surgery?
Conclusion
The study found that obesity, the size of the remaining rectum, total mesorectal excision, anastomotic complications, and prolonged ileostomy time are significant factors in the development of LARS.
Supporting Evidence
- Up to 80% of patients can develop symptoms of LARS after rectal surgery.
- Obesity and diabetes were significantly correlated with the presence of LARS.
- The LARS score decreased in most patients during the 2-year follow-up.
- Major LARS at 6 months after surgery may predict the need for a definitive colostomy.
- Patients with major LARS had a higher likelihood of requiring a colostomy.
Takeaway
Some people who have surgery for rectal cancer can have problems with their bowel movements afterward, which is called LARS. This can happen for various reasons, like being overweight or having complications during surgery.
Methodology
A retrospective study was conducted on 102 patients who underwent rectal cancer surgery, assessing their demographics, clinical history, and LARS symptoms over a 2-year follow-up.
Potential Biases
The study may be biased due to the exclusion of patients who underwent laparoscopic or robotic procedures.
Limitations
The study is limited by its retrospective nature, single-center design, and relatively small sample size.
Participant Demographics
The group included 68 men and 34 women aged between 35 and 88.
