CRC, with a median age at diagnosis of about 70 years (3). Further, in patients aged ≥90 years, CRC accounts for more than one-fifth of new cancer diagnoses (4).Surgical treatment remains the mainstay for resectable CRC. However, surgery is not always performed on nonagenarians with CRC due to the risk of complications relating to age, comorbidity, and reduced functional
Background
The impact of self‐expandable metal stent (SEMS) for malignant right colonic obstruction remains undefined. The aim of this study was to compare short‐term postoperative and long‐term oncologic outcomes of colonic stenting as a bridge to surgery (SBTS) and urgent colectomy for patients with malignant right‐sided obstruction.
Methods
A total of 98 consecutive patients who underwent SEMS placement during the period 2004–2015 from three hospitals were included. For comparative analyses, patients were matched (1:2) with 196 patients treated with emergency colectomy from our prospective database.
Results
The two groups were comparable in terms of demographics and tumor characteristics. The proportion of patients who underwent laparoscopic colectomy was higher in SBTS group than urgent colectomy group (75.5% vs. 37.2%; p < 0.001). Patients treated with SBTS were less likely to have a temporary stoma constructed (3.1% vs. 10.7%; p = 0.024). SBTS was associated with significantly less median estimated blood loss (90 vs. 100 ml; p = 0.029), shorter length of hospital stay (11 vs. 12 days; p < 0.001), lower overall postoperative complication rate (18.4% vs. 31.3%; p = 0.018), and wound‐related complication rate (5.1% vs. 14.3%; p = 0.019) compared with urgent surgery. Reoperation rate, 30‐day mortality, and lymph nodes harvested were not significantly different between two groups. Disease‐free survival rate and overall survival rate were similar between the two groups.
Conclusions
SEMS insertion is safe and feasible for treating malignant right‐sided obstruction. SBTS is associated with better short‐term outcomes and equivalent long‐term oncologic results compared with urgent colectomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
