INDEPSO-ISPSM consensus on peritoneal malignancies - Enhanced recovery after surgery in cytoreductive surgery (CRS)...

The role of enhanced recovery after surgery (ERAS) in cytoreductive surgery and/or Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is evolving, with promising results that improve patient outcomes. This consensus exercise was carried out to address and standardize components of the ERAS protocol pertinent to the Indian context.

The modified Delphi method was employed with two rounds of voting. All fifty invited specialists agreed to vote. There were 30 questions addressing the key elements of ERAS protocols. They were broadly distributed across four sections: Prehabilitation, Preoperative, Intraoperative, and Postoperative elements. A consensus was achieved if any one option received > 70 % votes (strong consensus > 90 %). If consensus was not achieved in round 1, the question was moved to round 2.

After rounds I and II, 48/50 (95.8%) of invited panelists voted for the questions. The highest rate of 'skipped question' was 6% in both rounds. A consensus was obtained for 28/30 (93.33%) questions, and strong consensus was obtained for 5/30 (16.6%) questions. No consensus was obtained for two questions. Some of the panelists' recommendations contradicted the standard ERAS guidelines, such as using intraperitoneal drains in all patients and mechanical bowel preparation for left-sided colonic or rectal resections.

Despite some limitations, this consensus exercise represents a significant step toward advancement and pioneering efforts to improve patient outcomes by implementing and standardizing ERAS protocols in CRS and/or HIPEC tailored for India.
