Background: Portal vein system thrombosis (PVT) is an infrequent but potentially serious complication after laparoscopic splenectomy. Patients with β-thalassemia are at higher risk as they have splenomegaly and hypercoagulability. Subjects and Methods: Forty-eight β-thalassemia patients who underwent hand-assisted laparoscopic splenectomy or laparoscopic splenectomy were studied prospectively with pre- and postoperative Doppler ultrasonography or computed tomography scanning. Results: The incidence of PVT was 8.3% (95% confidence interval [CI] 0.2%-16.4%) (4 of 48 patients). Spleen weight was the only independent factor associated with the presence of PVT. The odds ratio for spleen weight (100 g increase) was 1.46 (95% CI 1.10-1.94, P=.010). Receiver operator characteristic curve analysis showed that the optimal cutoff of spleen weight to the prediction of PVT was 1543 g. Thrombosis resolution was observed after a median of 165 days. Conclusions: Patients with β-thalassemia who undergo laparoscopic-assisted splenectomy are at high risk of postoperative PVT. Close postoperative surveillance and aggressive coagulation prophylaxis are needed in these patients. Larger studies are required to confirm the present findings. © Mary Ann Liebert, Inc.

Background/Aims: Pseudomyxoma peritonei syndrome (PMP) may be associated with slow "benign" or malignant process. However, the natural history of this disease is slow progression to death. Its treatment is variable and controversial. In this current study we have compared the patients with Pseudomyxoma peritonei syndrome with recurrences due to the cell entrapment hypothesis. Methodology: Data were derived from a database of patients with PMP treated at our hospitals from 2004 to 2009. All patients had undergone various surgical operations prior to referral to our institutions for definitive treatment. All patients had recurrences in special sites due to entrapment of malignant cells. Results: There are 6 patients, four men and two women. The initial clinical presentation of the disease was hernia in one, appendicitis in three and ovarian mass in one. The mean time from the initial operation to be definitive management was 23.5 months with an average of 1.83 operations per patient. After cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC) the mean survival was 31 months with minimal recurrences and only 0.3 operations per patient. Conclusions: Our data suggest that the patients should be referred to a center with a peritoneal surface malignancy program after the PMP diagnosis as soon as possible. Incomplete debulking procedures and minimal invasive operations promote uncontrollable intra-abdominal tumor growth due to tumor cell entrapment and the tendency of PMP to grow at wound sites. © H.G.E.
