| Non-hospitalization ambulatory surgery has already been an officially approved standard surgical method in the U.S.A. Patients are discharged on the same day after surgery in the Harvard medical school hospital of MGH with follow-up check 3 to 4 weeks after the surgery, not visiting the clinic the next day unless they have any special problems. |
|
| The reason why the ‘non-hospitalization surgery’ became possible... |
|
| Recently the far advanced surgical technique for hemorrhoids have been developed and it does not require hospitalization because it decreases significantly in postoperative complications of bleeding, urinary retention and severe postoperative pain, even in the cases of longstanding huge hemorrhoids. |
|
| Medical scientific researches revealed early ambulation after surgery without hospitalization has advantage of decreasing postoperative complications such as urinary retention and thromboembolism. |
|
| In the past hemorrhoidectomy had required hospitalization for 3 to 7 days and follow-up outpatient visits for 3 to 4 weeks. The surgery for complicated anal fistula had required hospitalization for one or two weeks and follow-up outpatient visits for 4 to 8 weeks. |
|
| However, nowadays extremely large hemorrhoids and complicated anal fistula can be treated by non-hospitalization ambulatory surgery. |
|
| Patients can start to work the next morning after surgery because they usually do not need hospitalization or outpatient treatment. Some very busy patients worked on the same day after surgery. |
|
| Patients can sit down on the chair immediately after surgery and can go home by self-driving the same day after surgery. From the next day after surgery patients can enjoy playing golf, football, ballet, climbing etc. Patients can travel abroad one or two days after surgery in the most cases. |
