Background and Aims. Intraperitoneal chemotherapy is a basic tool in the treatment of peritoneal malignancy. The purpose of the study is to investigate the effect of adjuvant perioperative intraperitoneal chemotherapy in the treatment of locally advanced colorectal cancer. Patients and Methods. Patients with T3 and T4 colorectal carcinomas that underwent R0 resection received either hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC group = 40 patients) or early postoperative intraperitoneal chemotherapy (EPIC group = 67 patients). The survival, the recurrences and the sites of recurrence were assessed. Results. The 3-year survival rate for HIPEC group was 100% and for EPIC group 69% (P = .011). Nodal infiltration was found to be the single prognostic indicator of survival. The incidence of recurrence in EPIC group was higher than in HIPEC group (P = .009). The independent indicators of recurrence were the use of HIPEC and the degree of differentiation (P < .05). Conclusions. Intraperitoneal chemotherapy, particularly HIPEC, as an adjuvant in locally advanced colorectal carcinomas appears to improve survival and decrease the incidence of recurrence.

Background and Aims. 5-year survival in patients with pancreatic cancer is poor. Surgical resection is the only potentially curative resection. The results of adjuvant treatment either with chemotherapy or with radiotherapy have been contradictory and the incidence of local-regional recurrence remains high. If local-regional recurrence is controlled survival may be expected to increase. Hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) may be used in order to control local-regional recurrences. The purpose of the study is to identify the effect of HIPEC in patients with pancreatic cancer undergoing potentially resection. Patients and Methods. From 2007–2011, 21 patients, mean age 69.4 ± 9.5 (50–86) years, underwent tumor resection, and HIPEC with gemcitabine. The hospital mortality and morbidity rate was 9.5% and 33.3%, respectively. 5-year and median survival was 23% and 11 months, respectively. The recurrence rate was 50% but no patient developed local-regional recurrence. No patient was recorded with gemcitabine-induced toxicity. Conclusions. This clinical study of 21 patients is the first to combine an R0 pancreas cancer resection with HIPEC. Increased morbidity and mortality from intraoperative gemcitabine was not apparent. Patients with pancreatic cancer undergoing potentially curative resection in combination with HIPEC may be offered a survival benefit. Data suggested that local-regional recurrences may be greatly reduced. Further studies with greater number of patients are required to confirm these findings.

Cytoreductive surgery with HIPEC has provided a chance for long-term survival in selected patients. However, perioperative management remains a challenge for the anesthesiology team. The aim of this study was to evaluate the changes in hemodynamic parameters during hyperthermic intraperitoneal chemotherapy (HIPEC) using the FloTrac/ Vigileo system. Forty-one consecutive patients undergoing cytoreductive surgery and HIPEC were enrolled. Heart rate (HR), esophageal temperature, and cardiac output (CO) steadily increased until the end of HIPEC. In the first half of HIPEC, systolic blood pressure (SBP) and central venous pressure (CVP) increased whereas systemic vascular resistance (SVR) decreased; SVR stabilized in the second half. Diastolic blood pressure (DBP), mean arterial pressure (MAP), and stroke volume (SV) showed no significant variation. Male gender was related to increased CVP, CO, and SV, and decreased SVR; age .55 years was related to increased SBP, and peritoneal cancer index (PCI) was correlated with HR, DBP, and SV. PCI .14 was associated with increased HR and decreased DBP and MAP. American Society of Anesthesiologists score .1 was related to decreased CO and SV. Patients undergoing HIPEC develop a hyperdynamic circulatory state because of the increased temperature, characterized by a steady decrease in SVR and continuous increase in HR and CO. FloTrac/Vigileo system may provide an easy-to-handle, noninvasive monitoring tool.

Perforation of the liver hydatid cyst into hollow abdominal organs is an extremely rare complication. A case of two synchronous hydatid cysts in an old lady is presented. The patient had one multilobular cyst perforated into the right colon and another one uncomplicated located at the right ovary. She underwent partial cystectomy, omentoplasty, right hemicolectomy, and total hysterectomy, and had an uneventful recovery.

Secondary cytoreduction with intraperitoneal chemotherapy is feasible in most women with recurrent ovarian cancer with acceptable morbidity and mortality. Complete cytoreduction is not possible if distant and unresectable metastases are present or if the small bowel is extensively seeded. Long-term survivors are patients with limited peritoneal dissemination who may undergo complete cytoreduction.
