Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal carcinomatosis from small bowel adenocarcinoma.

Peritoneal carcinomatosis arising from small bowel adenocarcinoma (PCSBA) carries a dismal prognosis. Presently, limited data have been published on the outcome of PCSBA treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC). This series represents the largest series published to date examining our experience with 17 patients. From 1995 to 2011, 17 patients underwent HIPEC with mitomycin for PCSBA. Patients in this study were identified from a prospectively maintained database. Twenty HIPEC procedures were performed on 17 patients with a mean age of 52.2 years. Patients have achieved a mean overall postoperative survival of 18.4 months after progression on chemotherapy with an overall postoperative one- and three-year survival of 52 and 23 per cent, respectively. The mean total length of hospital stay was 10 days. There was no treatment-related mortality. Six patients were readmitted to the hospital within 30 days of discharge (35%). Eight patients (47%) experienced postoperative complications, in which two patients had major postoperative complications in the form of intra-abdominal abscess requiring interventions (12%). HIPEC has encouraging survival results for patients with PCSBA compared with similar patients treated with conventional treatments. However, even with such advancement in management, treatment for small bowel adenocarcinoma still remains a challenge.
