Introduction: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are being widely used in the treatment of patients with peritoneal surface malignancies. The open procedure has been associated with high grade III and IV morbidity and prolonged hospitalization. Methods: Patients with peritoneal surface malignancies and no gross evidence of carcinomatosis on the computed tomographic scan were enrolled to undergo laparoscopic CRS and HIPEC. We aimed to assess the feasibility, safety, and outcome of this procedure. Postoperative complications were reported according to the National Cancer Institute Common Toxicity Criteria. Results: From October 2008 to January 2010, 14 patients were enrolled into the protocol. Amongst these 14 patients, one patient was found with extensive carcinomatosis at the time of laparoscopy and had no surgical procedure. Thirteen patients had a complete cytoreduction and HIPEC, 10 (77%) laparoscopically and 3 (23%) were converted to an open procedure. There was one grade 3 morbidity (10%) and one patient (10%) in the laparoscopy group experienced a grade 4 complication, needing a reoperation for an internal hernia. Mean length of hospital stay was 6 days for those completed laparoscopically, 8 days for those converted to an open procedure and 8 days for a matched cohort of patients with an upfront open procedure. Conclusions: This initial investigative stage demonstrates the feasibility and safety of cytoreductive surgery and HIPEC via the laparoscopic route in selected patients with low-tumor volume and no small bowel involvement mainly from appendiceal malignancies. Longer follow-up and additional studies are required to evaluate its long-term efficacy.
