There are limitations in published literature on VR. The available data indicate that VR has low recurrence and improves FI in patients suffering from these conditions. There is a greater reduction in postoperative constipation if VR is used without posterior rectal mobilization.

Retroperitoneal sarcomas (RPS) are rare cancers that often reach massive size before detection. The mainstay of treatment for RPS is surgical resection, and complete resection is the only chance for potential cure. The management of RPS can be challenging and in individual cases, radiation and systemic therapy may be beneficial in both primary and recurrent disease. Further research through multi-institutional collaboration, ideally on a global level, is needed to better understand RPS and optimize management of this disease.

Currently there is little evidence for the effectiveness of injectable bulking agents in managing passive FI. The inability to obtain results from two further RCTs concerned the reviewers and hindered their ability to make strong recommendations. The identified injectable bulking agents appear to be safe with only minor complications reported.

The results of this study show clearly that every patient with SRUS must be assessed individually. Initial treatment should include conservative measures. In patients with refractory symptoms, surgical treatment should be considered. Results of anterior resection and protocolectomy are satisfactory for solitary rectal ulcer.
