Among patients with clinical success, the in\u2010hospital course and 1\u2010year cumulative recurrence were compared between the successful detorsion and successful decompression groups.

Among 22 patients with failed detorsion, 17 achieved clinical success after decompression, whereas five had clinical failure, including four who underwent emergency surgery and one who died the following day. The overall clinical success rate was 88.4% (38\/43). Failed detorsion was associated with lower room\u2010air oxygen saturation and higher lactate levels. Clinical success was less frequent in the failed detorsion group (77.3%\u00a0vs. 100%,\n                      <jats:italic>p<\/jats:italic>\n                      = 0.065), and hospital stay was longer (median 13\u00a0vs. 7 days,\n                      <jats:italic>p<\/jats:italic>\n                      = 0.071).
