Abstract
Patients with an oncologic disease requiring cytoreductive surgery and hyperthermic intraperitoneal chemotherapy may also present with morbid obesity. In some patients, it may be possible to offer bariatric surgery such as sleeve gastrectomy in combination with their cancer resection to treat both diseases concurrently. Two such cases are described where sleeve gastrectomy was done alongside the primary oncologic surgery in the same procedure. Our patients had long-term follow-ups and their overall outcomes were favorable. They achieved remission and acceptable levels of weight loss over their several years of follow-up appointments. The added benefit of bariatric surgery may decrease long-term morbidity and mortality in carefully selected patients. More studies are indicated to fully understand the risks of benefits of this combined procedure in order to offer it on a wider scale.
