An agitated patient barricaded himself in a room and jumped from a ground-floor window during one of 11 "never event" incidents at Ipswich Hospital since 2021.
The trust which runs Ipswich Hospital has revealed a number of incidents to have happened in the last few years, which included patients with foreign objects left inside them after procedures and wrong patients treated.
East Suffolk and North Essex NHS Foundation Trust, which runs the hospital, said patient safety is a "top priority" and said lessons would be learned.
One of the incidents included an agitated patient, who had received chlordiazepoxide doses during the night, wanting to go home and swearing.
He then barricaded himself in a side room, where at least one security officer was present and trying to persuade him to unblock the door, and then jumped out of the ground floor-level window.
In another incident in March this year, a patient who had a gauze inserted into the vagina in a previous cystoscopy was found to have the same object still intact in the vagina in the repeated procedure.

A "never event" is defined by the NHS as a "serious incident" that is "wholly preventable" by guidance or safety recommendations which "should have been implemented".
Of the 11 recorded in Ipswich from 2021 to 2024, the wrong patient was treated three times when their identity was not confirmed.
This included a patient, who is "quite deaf" according to records, walking into the injection room after a different name was called, and being given the wrong intravitreal injection.
Surgery was given on the wrong site in four cases, two of these on the wrong side of the body despite the correct site being confirmed.
The information was revealed by ESNEFT in a response to a Freedom of Information request made by this newspaper.
Anne Rutland, the trust's interim chief nurse, said: “Patient safety is our top priority at all times. On the rare occasion when an incident or near-miss happens we investigate thoroughly and in line with national guidance.
“We are committed to using lessons learnt from investigations to prevent similar incidents happening again, and we share findings and learning across the organisation as well as with the patient involved.”
