Objective To discuss the surgical management in resection of primary peritoneal tumors involving iliac vessels. Methods The clinical data of 124 patients with primary peritoneal tumors involving iliac vessels， that underwent surgical procedures from December 2006 to December 2011 were analyzed retrospectively. There were 68 menand 56 women with an age raging from 16-72 years old （mean 44 years old）. Results All patients underwent operative treatment. Fifty-two patients with tumors infiltrating or surrounding the major illiac vessels， 72 patients with tumors compressing the iliac vessels. Primary peritoneal tumors involving iliac vessels were completely resected in 90 patients， were incompletely resected in 31 patients， and were palliatively resected in 3 patients. Resectoin of primary peritoneal tumors and iliac vessel reconstruction were performed in 42 patients with tumors infiltrating or surrounding the major illiac vessels. There was no death during perioperative period. There were complications in 2 patients， that including urinary fistula in 1 patient and fat liquefaction of incision in 1 patient. Complications were not found in the rest of the patients. All patients were followed-up from 12-24 months （mean 16 months）. Thirty-eight patients relapsed locally in 90 patients with tumor completely resected. Nine patients died in those tumor incompletely resected（6 patients died because of recurrence， 3 patients died because of cadiovasuclar and cerebrovascular accidents）. Three patients follwing palliative resected were dead during the follow-up period （3 patients died because of recurrence）. Among the 42 patients underwent the procedure of iliac vessels， recurrence occured in 3 patients without involving iliac vessels， 1 patient relapsed involving inferior vena cava （IVC） which resulted in IVC obstruction and deep venous thrombosis following 7 months after operation. Recurrence occured in 2 patients involving common iliac veins following 8 months after operation. Venous thrombus of common iliac vein graft occured in 1 patientin in 10 months after operation. Conclusion Resection completely and involved iliac vessel reconstruction would reduce recurrence of tumor and promote long term survival in patients with primary peritoneal tumors involving iliac vessels
ObjectiveTo discuss the treatment of retroperitoneal tumors infiltrating celiac trunk. MethodFifteen cases of retroperitoneal tumors who underwent surgery in our hospital between December 2014 to December 2015 were reviewed and analyzed. ResultsAll of the 15 cases had underwent operation, and the blood loss was 300-2200 mL (mean of 600 mL), operation time was 125-600 minutes (mean of 240 minutes). Length of stay in cases of celiac trunk resected was 10-23 days (mean of 15.1 days), and length of stay in cases of celiac trunk nonresected was 15-132 days (mean of 35.2 days). Thirty cases of them were complete resection, and 2 cases were mostly resection. Eight cases of them did not injure celiac trunk, 1 case suffered from complication, 7 cases injured celiac trunk and all of them suffered from complication. There were significant statistical difference in incidence of complications (χ2=8.14, P=0.01) in cases of celiac trunk injury or not. All the cases were followed up for 3-13 months (mean of 6.3 months), 2 cases recurred during the follow-up period, 1 case was leiomyosarcoma, and another 1 was malignant fibrous histiocytoma who underwent celiac trunk resection. ConclusionsWhen retroperitoneal tumors infiltrates celiac trunk, we can resect the celiac trunk, but we must follow a certain principle.
