The evaluation of feasibility of ambulatory laparoscopic cholecystectomy using intraoperative instillation of bupivacaine: a retrospective observational study.

Abstract

This study aimed to compare outcomes of opioid patients-controlled anesthesia (PCA) and intraoperative local anesthesia in terms of postoperative pain, lab results, patient surveys, and discharge scores to evaluate the feasibility of ambulatory laparoscopic cholecystectomy (LC). Patients who underwent LC for acute cholecystitis were assigned to the outpatient surgery (OPS) group or inpatient surgery (IPS) group according to the surgeon. In the OPS group, a mixture of bupivacaine and epinephrine was injected into trocar sites and sprayed on the surgical dissection field. Oral opioid and analgesics were given twice a day. In the IPS group, patients received opioid PCA. Numeric rating scale (NRS) for walking, erythrocyte sedimentation rate (ESR), CRP, self-assessed survey on general physical condition and discharge, and discharge score of ambulatory surgery were assessed postoperatively. NRS was significantly lower in the OPS group. There were no significant differences in ESR and CRP between the groups. Self-assessed survey on general conditions and the possibility of discharge were significantly better in the OPS group. The discharge scores at 3, 6, and 9 hours were significantly higher in the OPS group. Intraoperative instillation of bupivacaine at port sites and dissection fields had a better effect on short-term postoperative pain, patient surveys, and discharge criteria of ambulatory surgery than opioid PCA.
