Arm port vs chest port: A systematic review and meta-analysis

Abstract

Background: Two prevailing, totally implantable venous access ports are routinely utilized in oncology: chest port or arm port. This systematic review with meta-analysis was conducted to compare safety and efficiency of the two techniques. Methods: We performed evidence acquisition intensively from PubMed, Embase, and Cochrane Library. Available comparative studies that evaluated both techniques were identified. The outcomes of interest included total complication events, procedure-related infections, thrombosis, intra-operative complications, mechanical complications, conversion rate, early port removal, and operating time. Results: Thirteen comparative studies including 3,896 patients (2,176 for chest ports, and 1,720 for arm ports) were identified. The present study showed that arm port was associated with higher procedure conversion rate (2.51% in chest port group and 8.32% in arm port group; odd ratios [OR] 0.27, 95% confidence interval [CI] 0.15-0.46; p<0.001), but lower incidence of intra-operative complications (1.38% in chest port group and 0.41% in arm port group; OR 2.38, 95% CI 1.07–5.29; p=0.03). There were no between-group differences with respect to total complication events, procedure-related infections, thrombosis, mechanical complications, early port removal, and operating time. Subgroup analysis of patients under 60 years revealed that no significant difference was detected in intra-operative events (1.19% in chest port group and 0.02% in arm port group, OR 2.59, 95% CI 0.74–9.08; p<0.14), indicating that age may be a risk factor for intra-operative events. Sensitivity analysis did not change conclusions of all endpoints of interest. Conclusion: Arm port is associated with higher procedure conversion rate, but lower incidence of intra-operative complications, and age may be a risk factor for intra-operative events.
