[Pain and convalescence after ambulatory inguinal herniotomy during local anesthesia]

Postoperative pain and convalescence following ambulatory inguinal herniotomy in local infiltration anesthesia was evaluated in this descriptive study. Sixty consecutive patients (median age 63 yr) were included. Per- and postoperative pain treatment were pre- and postoperative oral tenoxicam and methadone plus infiltration of the surgical field with up to 60 ml of 0.25% bupivacaine. Intraoperative pain intensity was slight and was treated with supplemental bupivacaine. Patients were totally relieved of pain at rest and during mobilisation in the first hours after surgery, but more than half of the patients had moderate pain from the first to the third postoperative day and still had light pain seven days after surgery. Normal daily activity was re-established five days postoperatively (median). Fifty-two patients were satisfied with the anesthesia and eight patients not satisfied due to fear of intraoperative pain. This study shows that inguinal herniotomy can be performed routinely as an outpatient procedure under local infiltration anesthesia. However, late postoperative pain was significant and should be improved with multi-modal analgesia.
