Title: 5-year Oncological Outcomes in Left-sided Malignant Colonic Obstruction: Stent as
Bridge to Surgery
Version: 3 Date: 02 Jul 2023
Reviewer's report:
This study investigates long-term oncologic outcomes of colonic stent placement as a bridge
to surgery in malignant colonic obstruction compared to upfront surgery. Presentation of 5-
year survival results is impressive, but retrospective nature and small sample size are significant
limiting factors that were also noted by the authors.
Major issues:
1. Were there any adverse events related to SEMS placement? They are mentioned in the
Methodology, but not reported in the Results section.
2. How were patients selected to receive SEMS as a bridge to surgery vs undergo upfront
surgery? Did you have reliable preoperative clinical staging results in all cases?
3. Were prognostic factors also tested in multivariate regression analysis?
Minor issues:
1. Table legends are missing in Table 1. Please clarify abbreviations.
2. What were the reasons for total colectomy?
