Cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (HIPC) is a promising treatment for patients with peritoneal malignancies. Traditionally, HIPC is performed concurrently with cytoreductive surgery. However, this strategy is associated with significant morbidity and mortality. In this report, we describe our initial experience with staged laparoscopic infusion of HIPC. Five patients underwent complete open cytoreductive surgery followed by staged laparoscopic HIPC several weeks later. Primary malignancies included adenocarcinoma of the ileum (one patient), adenocarcinoma of the appendix (three patients), and adenocarcinoma of the gallbladder (one patient). At a subsequent operation, we performed laparoscopic HIPC. Quality of life was measured with the Functional Assessment of Cancer Therapy-Colon Subscale (FACT-C). Mean inflow and outflow cannula temperatures were 42.1 degrees C and 40.5 degrees C, respectively. Mean peritoneal perfusion flow rates were 689.8 ml/minute. The hospital stay for all patients was 1 to 2 days. One patient developed postoperative cellulitis, one patient died of progressive tumor, and four patients are alive without tumor progression. Quality-of-life measurements had returned to baseline 4 months after treatment. Staged laparoscopic HIPC after open cytoreductive surgery is safe, feasible, and can achieve uniform temperatures and perfusion flow rates. Although the results of this pilot study are encouraging, additional studies are required to determine long-term survival and quality of life.

Intraductal papillary neoplasm of the bile duct (IPNB) has been widely recognized. However, the knowledge of intracystic papillary neoplasm of the gallbladder (IPNG) including papillary adenoma and adenocarcinoma is not well defined. In this study, we compared the clinicopathological and immunohistochemical features between 32 IPNG cases and 32 IPNB cases. IPNG-1 (low-high grade dysplasia) exhibited an earlier onset age, smaller tumor size and lower level of CK20 expression compared to IPNG-2 (invasive carcinoma). Histologically, pancreaticobiliary and intestinal subtype accounted for nearly half of IPNG or IPNB (44.4% and 48.1% vs. 44.0% and 44.0%), respectively. Immunohistochemically, 88.9% of IPNG and 92.0% of IPNB cases were positive for MUC1, and 96.3% and 92.0% for CK7, respectively. CDX2 and MUC2 were more highly expressed in the intestinal subtype than in other subtypes. CK20 expression increased in parallel with tumor progression. In addition, 53.1% of IPNG cases and 68.6% of IPNB cases exhibited invasive carcinoma, and showed significant survival advantages to conventional gallbladder adenocarcinoma and cholangiocarcinoma, respectively. In conclusion, papillary adenoma and adenocarcinoma of the gallbladder can be recognized as different pathological stages of IPNG, and they share pathological features with IPNB.
