Patients in Brighton and Hove are staying in hospital nearly a day longer on average after operations than they did two years ago.
The average stay has risen from 2.6 days in 2007-08 to 3.4 days last year (2009-10).
The figures were collated by the NHS Information Centre and given in a parliamentary written answer by Health Minister Simon Burns.
He was responding to a fellow Conservative Mary Macleod, the MP for Brentford and Isleworth.
He gave a breakdown of the average length of stay for patients after operations broken down by primary care trust.
In 2007-08 Brighton and Hove City Teaching Primary Care Trust patients had the second shortest average post-op stay in hospital in the country.
By last year 45 out of 153 trusts reported shorter average stays.
Shorter stays in hospital are regarded as cheaper and they free beds for incoming patients. They are also regarded as reducing the likelihood of a patient suffering a hospital-acquired infection such as MRSA.
