Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are the treatment of choice for select patients with peritoneal surface malignancies; however, the traditional open approach may be associated with significant morbidity. We evaluated postoperative outcomes with minimally invasive (MI) CRS and HIPEC.Review of our institutional database identified 47 patients who underwent optimal cytoreduction (CC0 or CC1). Those with a PCI ≤ 15 and primary malignancy of gastrointestinal origin were then selected for subgroup analysis. Multivariable regression was performed to identify factors impacting postoperative outcomes.Demographic data did not significantly differ between open (n = 24) and minimally invasive (n = 9) groups. The MI group had a mean age of 57.34 ± 14.92, BMI of 27.03 ± 4.27, Charlson comorbidity score of 1.78 ± 1.72, and PCI of 5.56 ± 5.08. Mean time to flatus (days) was 2.78 in the MI group and 5.04 in the open group (p 0.001), and mean length of IV analgesic use (days) was 3.11 in the MI group compared to 6.00 in the open group (p = 0.006). Mean length of stay (days) was 5.11 in the MI group and 8.67 in the open group (p = 0.033). Surgical approach (p = 0.037) and BMI (p = 0.039) were the only factors impacting length of stay.Minimally invasive CRS and HIPEC is an excellent option for low volume peritoneal disease of gastrointestinal origin. A minimally invasive approach yields faster return of bowel function, reduced postoperative analgesia requirements, and shorter hospital stay.

Background While overall cancer incidence and mortality have decreased over the last decade, hepatocellular carcinoma (HCC) cases have increased sharply. Objective This study set out to evaluate the utility of surgery for resectable single tumor HCC in this setting. Patients and methods This study analyzed the National Cancer Database, selecting all patients with a histological diagnosis of HCC and an isolated tumor (≤5 cm) treated with radiofrequency ablation (RFA) or surgical resection. Results A total of 7821 patients were identified for this study. In the patients with a single tumor up to 3 cm, 40% had a surgical resection and 60% had RFA. In the group with a tumor 3.01-5 cm, 62% had a surgical resection and 38% had RFA. Patients with a single tumor up to 5 cm had a 3-year survival of 60% after resection compared to 42% with RFA. When the patients were split into those with a tumor up to 3 cm or a tumor 3.01-5 cm, there was a survival benefit in the surgical resection cohort. Conclusion Surgical resection may be underutilized in the USA for resectable HCC, especially in patients with a tumor up to 3 cm.
