OBJECTIVE
Evaluation clinical outcomes of stenting and decompressive surgery in patients with colorectal obstruction due to unresectable locally advanced cancer and carcinomatosis.
MATERIAL AND METHODS
A retrospective analysis of palliative treatment of 73 patients with large-bowel obstruction was performed. Criterion of inclusion — presence of unresectable primary, recurrent or metastatic locally advanced tumour with invasion to adjacent tissues and/or peritoneal dissemination. Patients underwent colorectal stenting (39) or decompressive surgery (34) (loop colostomy — 29, ileotransverse bypass — 5). Left-sided obstruction was observed in 64 (35/29) patients, right-sided — in 9 (4/5) patients. Location of tumour: colorectal cancer — 57 (29/28), extracolonic tumour — 16 (10/6) patients.
RESULTS
Complications occurred in 3 patients (7.7%) after stenting and in 11 (32.4%) after surgical palliation (p=0.0083) with post-procedure mortality 5.1% (2 patients) vs. 14.7% (5 patients), p=0.2675. Stoma complications and wound infection prevailed among surgical adverse events; all stent-related complications included bowel perforation. General adverse events were observed in 5 patients after colostomy vs. 0 after stenting (p=0.0185). Hospital stay was shorter for stenting (p=0.0010).
CONCLUSION
Stenting and loop colostomy or bypass appear to be equally effective for management of large bowel obstruction in patients with locally advanced unresectable cancer of various etiology, including extracolonic, recurrent and metastatic tumours. In comparison to decompressive surgery colorectal stenting is less invasive, has an advantage of fewer adverse events, shorter hospital stay, absence of stoma and therefore may be recommended as a final palliation.
