| Outcomes |
Surgical benefit: defined as survival > 60 days without symptoms of incomplete or complete obstruction: 8/19 (42%)
Re‐obstruction: 3/8 (38%) median time 106 days (100 to 200 days)
Postoperative mortality: within 30 days: 32%
Postoperative morbidity: 64%
Median survival: 68 days (7 to 919) |
| Notes |
23 had small intestinal obstruction, 13 had large intestinal obstruction, and 5 combined
13 patients had colostomy +/‐ resection, 4 had bypass +/‐ resection, 2 lysis of malignant adhesions
