As a viable option, BIPSC with CRS and HIPEC for patients with PC arising from GC may be performed safely, with acceptable morbidity and mortality, in a specialized unit. Response to BIPSC, optimal CRS and limited peritoneal dissemination seem to be essential to achieve the best outcomes in these patients.

Endoscopic surgery of the neck is safe, minimally invasive, and produces excellent cosmetic results. However, it is in an early stage of development. Techniques have yet to be standardized, and specialized instruments are not available. The field is likely to mature as surgeons gain more experience.

Background. Even though cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are associated with a high morbidity and mortality rates, it has been reported that CRS and HIPEC improved survival of selected patients with peritoneal carcinomatosis. We aimed to report morbidity and mortality results of CRS and HIPEC from a single institution in Japan. Methods and Results. Total of 284 procedures of CRS were performed on patients with pseudomyxoma peritonei, peritoneal carcinomatosis (PC) from colon cancer and gastric cancer between 2007 and 2011 in our institution. The morbidity rate was 49% of all procedure, and grades I/II and grades III/IV complications were 28% and 17%, respectively. Most frequent complication was surgical site infections including intraabdominal abscess. The mortality rate was 3.5%, and reoperation was needed in 11% of all procedures. Univariate and multivariate analysis showed peritoneal carcinomatosis index (PCI) greater than 20 was the only significant factor for occurrence of postoperative complications (P < 0.01). In contrast, HIPEC significantly reduced postoperative complications (P < 0.05). Conclusions. The morbidity and mortality rates of our institution are comparable with previous reports that are in acceptable rates. Optimal patient selection such as patients with PCI less than 20 seems to be of paramount importance to CRS and HIPEC.

Recent studies show that CRS plus intraperitoneal chemotherapy applications confer prolonged survival in patients with PSM from colorectal, gastric, ovarian, appendiceal mucinous carcinoma and diffuse malignant peritoneal mesothelioma. The comprehensive treatment is now justified as state-of-the-art for patients with peritoneal metastasis.

Until more data become available, a reasonable strategy for the treatment of SBM is CRS and HIPEC. It can be applied with acceptable safety in selected patients with peritoneal dissemination from SBM.
