Sartori 2010.
| Methods | Retrospective review | |
| Participants | 75 patients between 1984 and 2005 | |
| Interventions | 25 patients underwent surgery; 50 patients treated conservatively | |
| Outcomes | Postoperative deaths 8% (2 patients) All patients ‐ median survival 8 weeks, mean survival 19.6 weeks Surgical group ‐ median survival 28 weeks, mean survival 34 weeks (0 to 94 weeks), 8‐week survival 80% (20 patients) Conservative group ‐ median survival 4 weeks, mean survival 12 weeks (0 to 102 weeks), 8‐week survival 34% (17 patients) |
|
| Notes | 16% were found to be inoperable intraoperatively The authors also try to define a scoring system to determine the decision for surgery Same patient group as Sartori 2009 |

| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | High risk | "From 1984 to 2005, 270 patients with epithelial ovarian cancer were diagnosed and treated at the Department of Obstetrics and Gynaecology, University of Brescia. Seventy‐five (28%) cases developed bowel obstruction related to progression/ recurrence of disease." |
| Allocation concealment (selection bias) | High risk | "All clinical records of ovarian cancer‐related bowel obstruction were retrospectively reviewed and the necessary clinical data obtained." |
| Blinding (performance bias and detection bias) All outcomes | High risk | "All clinical records of ovarian cancer‐related bowel obstruction were retrospectively reviewed and the necessary clinical data obtained." |
| Blinding of participants and personnel (performance bias) All outcomes | High risk | "All clinical records of ovarian cancer‐related bowel obstruction were retrospectively reviewed and the necessary clinical data obtained." |
| Blinding of outcome assessment (detection bias) All outcomes | High risk | "All clinical records of ovarian cancer‐related bowel obstruction were retrospectively reviewed and the necessary clinical data obtained." |
| Selective reporting (reporting bias) | Unclear risk | Outcomes reported specifically for patients with bowel obstruction due to advanced ovarian cancer Outcomes reported for all 77 patients Results not reported according to surgical intervention |
