Comparative Outcomes of Loop Ileostomy and Loop Transverse Colostomy Following Curative Resection for Rectal Cancer

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Patient Outcomes

Background:

• Temporary fecal diversion using loop stomas (loop ileostomy [LI] and loop transverse colostomy [LTC]) is common after rectal cancer resection to prevent anastomotic leaks.
• Both LI and LTC have distinct complication profiles that can impact patient recovery and quality of life.

Purpose of the Study:

• To compare patient outcomes and quality of life between loop ileostomy and loop transverse colostomy following curative resection for rectal cancer.

Main Methods:

• A randomized comparative study involving 40 adult patients undergoing curative rectal cancer resection.
• Patients were randomized (1:1) to either LI or LTC.
• Quality of life was assessed using the 36-item short-form survey questionnaire.

Main Results:

• Loop ileostomy (LI) was associated with shorter creation time, earlier output, and reduced hospital stay.
• However, LI showed significantly higher 30-day complication rates, primarily dehydration and skin irritation.
• At one month post-surgery, loop transverse colostomy (LTC) patients reported a better quality of life and fewer pouch changes.

Conclusions:

• Loop ileostomy (LI) provides faster construction and earlier recovery but poses risks of metabolic and skin complications.
• Loop transverse colostomy (LTC) offers improved quality of life and fewer early complications, though surgery is longer.
• Patient-centered selection is crucial for optimizing surgical outcomes in rectal cancer treatment.
