ABSTRACT

<p><b>OBJECTIVE</b>To explore the clinical application technology of completely laparoscopy hepodectomy (LH).</p><p><b>METHODS</b>From June 2006 to December 2011, the 126 cases of LH were performed, the data including operating time, blood loss and postoperative complications, etc, were analyzed retrospectively. The patients included 87 males and 39 female and they were 28-83 years old with an average age of 44.5 years old. The parenchyma was transected using laparoscopic ultrasonic scalpel and ligasure, accomplished with endoscopic linear stapler. Of all the patients, the diseases performed LH including primary liver carcinoma (45 cases), liver hemoangioma (58 cases), colon carcinoma with livermetastasis (23 cases), liver focar (5 cases), liver granuloma (1 case), liver adenoma (4 cases). The operations included left hemihepatectomy (n = 17), left lateral lobectomy (n = 34), right hemihepatectomy (n = 15), segmentectomy (n = 22), local resection (n = 59).</p><p><b>RESULTS</b>Of all the patients, mean blood loss was 180 ml (10-1250 ml), mean surgical time was 142 minutes (43-220 minutes), mean postoperative hospital day was 2.2 days (3-12 days). Postoperative complications including eight cases of bile leakage, recovered after 1-3 weeks by appropriately draining. The patients with malignant tumor were followed up for 18 months (12-46 months), recurrence happened in 12 cases and four cases was died of recurrence and metastasis.</p><p><b>CONCLUSIONS</b>LH is a safe, feasible and effective procedure for the treatment of benign liver disease and malignant liver neoplasm as long as the patient is properly selected, it should be recommended for radical resection of hepatocellular carcinoma.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the clinicopathologic and immunohistochemical features, biological behavior, diagnosis and treatment of solid pseudopapillary tumor of the pancreas (SPTP).</p><p><b>METHODS</b>A retrospective clinical and clinicopathologic analysis was made on 33 cases of SPTP admitted from May 2001 to 2010 July. There were 7 male and 26 female patients, aging from 13 to 66 years with a mean of 34.3 years.</p><p><b>RESULTS</b>The tumor was located in pancreatic head of 10 patients, in pancreatic neck of 5 patients, in pancreatic body and tail of 18 patients. Of the 33 patients treated with surgery, 8 underwent simple resection of pancreatic tumor, 6 underwent pancreaticoduodenectomy, 3 underwent tumor resection plus pancreaticojejunostomy, 1 underwent tumor resection plus pancreaticogastrostomy, 11 underwent distal pancreatectomy, 4 underwent distal pancreatectomy plus spleen resection (1 underwent mesohepatectomy for hepatic metastasis). Sixteen of the 33 operations were completed by laparoscopy. Histologically, tumors were composed of papillary and microcystic solid structures, with uniformed population of cells. The pancreas and blood vessels invasion were identified in 3 cases, one of them was combined with liver metastasis, and they are male. Immunohistologically, the tumors were positive for α1-antitrypsin, α1-antichymotrypsin, β-catenin, CD10, CD56 and vimentin (all cases), neuron-specific enolase (3 cases), synaptophysin (6 cases), chromogranin A (4 cases), progesterone receptor (28 cases), estrogen receptor (3 cases), S-100 (6 cases). Totally 33 cases were followed up with a median period of 49 months without tumor recurrence.</p><p><b>CONCLUSIONS</b>SPTP is of low graded malignancy. It primarily affects young women. It may be located in any part of pancreas. Immunohistochemistry is very important for the diagnosis and differential diagnosis of SPTP. Surgical resection is recommended as the treatment of choice. Laparoscopic distal pancreatectomy or tumor resection is feasible and safe for some selected patients, and the prognosis is good.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the pathological feature of primary hepatic carcinoma and the clinical significance.</p><p><b>METHODS</b>From August 2000 to December 2007, there were 89 patients with cirrhosis and carcinoma of liver who accepted whole liver resection. The whole liver was cut into 10 mm slices to examine the tumor size, number, distribution, capsule, satellite nodes, portal vein tumor thrombi (PVTT). The invaded adjacent tissue and lymph nodes were recorded, the distance from satellite to major tumor was measured, then histological examinations were carried out, and the final diagnosis was made by pathologists.</p><p><b>RESULTS</b>The total of 89 cases included hepatocellular carcinoma in 86 cases and cholangiocarcinoma in 3 cases; 53 cases with multiple tumors and 36 cases with solitary tumor; complete capsule only in 14 cases, no obvious margin in 11 cases, 13 cases had a major tumor in the right lobe and a small tumor in the left lobe; 8 of 25 cases with gross invaded tissue were confirmed by histological examination, 7 of 16 cases with swollen lymph nodes were infiltrated by cancer cells. There were 47 cases with PVTT (47.2%) and 39 cases with satellite nodes (43.8%). PVTT and satellite nodes increased with the increase of sizes and the numbers of the tumors. The distance from satellite node to major tumor mostly were 0.5 - 3.0 cm.</p><p><b>CONCLUSIONS</b>The whole explanted liver can completely reflect the characteristics of growth and infiltration of hepatic carcinoma. Attention must be paid to the small cancer lesions in another lobe, distal satellite nodes from major tumor, and tumor thrombi in a small branch of portal vein, which can not be found by imaging, and might influence the curative effectiveness after liver resection or transplantation.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the feasibility, reliability and therapeutic effectiveness of adjuvant chemotherapy for advanced hepatocellular carcinoma (HCC) after orthotopic liver transplantation (OLT).</p><p><b>METHODS</b>The clinical data of adjuvant chemotherapy after OLT in 10 advanced HCC patients were studied retrospectively. FAP chemotherapy regimen was adopted calcium folinate (CF) 200 mg/m(2) and 5-Fluorouracil 500 mg/m(2) iv on D1 to D5, and doxorubicin 40 mg/m(2), cisplatin 30 mg/m(2) iv on D1, with 28 days as a cycle. The opportune time of chemotherapy, chemotherapy regimen, synergistic action between cytotoxic agent and immunosuppressive agent on liver and kidney and side-effects were preliminarily evaluated.</p><p><b>RESULTS</b>7/10 patients are surviving, with the longest survival of 32 months, and the shortest 9 months. Three patients died after operation, two at 13 months, one at 20 months after OLT, all died of metastasis. The incidence of one year survival was 9/9. During the period of chemotherapy, the side-effects of adjuvant chemotherapy were moderate.</p><p><b>CONCLUSION</b>Chemotherapy which is able to prolong the life-span of patients with advanced HCC after orthotopic liver transplantation is feasible and effective, the side-effects were mild. The choice of opportune time of chemotherapy might influence the outcome.</p>
