[Usefulness of Transnasal Decompression Tubes in Patients with Right-Sided Obstructive Colorectal Cancer].

PURPOSE: We performed this retrospective study to evaluate the usefulness of a transnasal decompression tube(long ileus tube)as a bridge to surgery in patients with right-sided obstructive colorectal cancer.

PATIENTS AND

METHODS

There were 8 patients(5 men and 3 women, aged 64 to 85 years with a mean age of 75.9 years)who had undergone transnasal decom- pression in the last 10 years.

RESULT: 1) The success rate of intubation was 100%(8/8). 2) Primary cancer location: Ascend- ing colon cancers were 37.5%(3/8)and right-sided transverse colon cancers 62.5%(5/8). 3) Decompression periods were from 1 to 43 days, with a mean period of 12.8 days. 4) Stage: Stage II was found at 12.5%(1/8), Stage II , III a, III b and IV were found at 25.0%(2/8), respectively. Advance Stages( III a, III b, and IV )were 75.0%(6/8). 5) Pathology: Well differentiated tubular adenocarcinoma(tub1)was at 37.5%(3/8)and moderately differentiated tubular adenocarcinoma (tub2)at 62.5%(5/8). 6) Operative procedures: Radical operation was performed in 6 cases except for 2 cases with stage IV disease. 7) Complications: Early complication were found in 37.5% of the cases(3/8). Wound infection was found in 12.5%(1/8), wound infection with rupture in 12.5%(1/8), and adhesive ileus in 12.5%(1/8). 8) Outcomes: The 5-year survival was 37.5%(3/8).

CONCLUSION

Transnasal tube decompression for right-sided malignant colorectal obstruction is useful for avoiding an emergency operation, and a single-stage operation can be performed in patients excluding Stage IV disease.
