Comparison of the prognosis of four different treatment strategies for acute left malignant colonic obstruction: a systematic review and network meta-analysis.

ABSTRACT:

Background

There is controversy regarding the efficacy of different treatment strategies for acute left malignant colonic obstruction. This study investigated the 5-year overall survival (OS) and disease-free survival (DFS) of several treatment strategies for acute left malignant colonic obstruction.

Methods

We searched for articles published in PubMed, Embase (Ovid), MEDLINE (Ovid), Web of Science, and Cochrane Library between January 1, 2000, and July 1, 2020. We screened out the literature comparing different treatment strategies. Evaluate the primary and secondary outcomes of different treatment strategies. The network meta-analysis summarizes the hazard ratio, odds ratio, mean difference, and its 95% confidence interval.

Results

The network meta-analysis involved 48 articles, including 8 (randomized controlled trials) RCTs and 40 non-RCTs. Primary outcomes: the 5-year overall survival (OS) and disease-free survival (DFS) of the CS-BTS strategy and the DS-BTS strategy were significantly better than those of the ES strategy, and the 5-year OS of the DS-BTS strategy was significantly better than that of CS-BTS. The long-term survival of TCT-BTS was not significantly different from those of CS-BTS and ES.

Secondary outcomes

compared with emergency resection (ER) strategies, colonic stent-bridge to surgery (CS-BTS) and transanal colorectal tube-bridge to surgery (TCT-BTS) strategies can significantly increase the primary anastomosis rate, CS-BTS and decompressing stoma-bridge to surgery (DS-BTS) strategies can significantly reduce mortality, and CS-BTS strategies can significantly reduce the permanent stoma rate. The hospital stay of DS-BTS is significantly longer than that of other strategies. There was no significant difference in the anastomotic leakage levels of several treatment strategies.

Conclusion

Comprehensive literature research, we find that CS-BTS and DS-BTS strategies can bring better 5-year OS and DFS than ER. DS-BTS strategies have a better 5-year OS than CS-BTS strategies. Without considering the hospital stays, DS-BTS strategy is the best choice.

Project description:BackgroundAlthough stent placement is increasingly performed, colostomy still is considered the gold standard for emergent relief of malignant colonic obstruction (MCO). This study aimed to compare hospital costs and clinical outcomes between patients undergoing colostomy and those undergoing stenting for the management of MCO.MethodsA retrospective claims analysis of the Medicare Provider Analysis and Review (MedPAR) data set was conducted to identify inpatient hospitalizations for colostomy or stent placement for the treatment of colon cancer (2007-2008). The outcomes evaluated using MedPAR compared the total length of hospital stay (LOS) and the costs associated with both techniques. Because MedPAR is a claims data set that does not provide outcomes at a patient level, a single-institution retrospective case-control study was conducted in which each stent placement patient was matched with two colostomy patients during the same period. Outcome measures (institutional data) were used to compare rates of treatment success, postprocedure LOS, and reinterventions between the two cohorts.ResultsThe MedPAR data evaluated 778 stent placements and 5,868 colostomy hospitalizations. There were no differences in gender, age distribution, or comorbidity between the two groups. Compared with colostomy, the median LOS (8 vs. 12 days; p<0.0001) and the median cost ($15,071 vs. $24,695; p<0.001) per claim were significantly less for stent placement. Stent placement was more commonly performed at urban versus rural hospitals (84% vs. 16%; p<0.0001), teaching versus nonteaching hospitals (56% vs. 44%; p=0.0058) and larger versus smaller institutions (mean bed capacity, 331 vs. 227; p<0.0001). The institution data included 12 patients who underwent stent placement and 24 who underwent colostomy. Although both methods were technically successful, the median postprocedure LOS (2.17 vs. 10.58 days; p=0.0004) and the rate of readmissions for complications (0% vs. 25%; p=0.01) were significantly lower for stent placement.ConclusionAlthough the technical and clinical outcomes for colostomy and stent placement appear comparable, stent placement is less costly and associated with shorter LOS and fewer complications. Dissemination of stent placement beyond large teaching hospitals located in urban areas as a treatment for MCO is important given its implications for patient care and resource use.
