Abstract
Aim : The aim of this study was to measure insulin resistance in laparoscopic colorectal resection, and to assess the significance of preoperative carbohydrate loading.
Patients and Method : A total of 27 patients (14 males, 13 females ; median age 68 years ; range, 38-78 years) who were scheduled for laparoscopic colorectal surgery were enrolled. For all patients the insulin resistance values on the day of operation in the morning, and immediately after the operation and on the morning after the operation were measured by HOMA-R.
Results : The median operating time was 137 minutes (range, 110-155 minutes), and operative blood loss was 10mL (range, 5-150mL). There was no conversion to open laparotomy. Of the 27 patients, 2 (7.4%) experienced postoperative complications, including 1 superficial surgical site infection and 1 paralytic ileus. There was no significant difference in the HOMA-R among the values for preoperative (1.4±0.6), immediately after operation (1.2±0.2) and on the morning after the operation (1.1±0.5).
Conclusion : Perioperative insulin resistance in laparoscopic colorectal resection was not increased. Carbohydrate loading for the purpose of alleviating insulin resistance may not be necessary when laparoscopic surgery is performed.
