Mesohepatectomy for the treatment of patients with centrally located hepatocellular carcinoma.

Mesohepatectomy is considered a feasible option for patients with centrally located hepatocellular carcinoma (HCC). However, mesohepatectomy is a technically demanding and less frequently used procedure. In this study, we summarized the surgical experience and evaluated the clinical outcomes of mesohepatectomy in 24 patients with centrally located HCC. Of these patients, 9 were treated with hepatectomy of Couinaud's segments IV, V and VIII with concurrent cholecystectomy; 8 underwent resection of segments IVb, V and VIII, including 7 patients who also received a cholecystectomy; 4 underwent hepatectomy of segments IVa, V and VIII; and 3 patients were treated with hepatectomy of segments I, IV, V and VIII, with concurrent cholecystectomy. The Pringle maneuver was used on 17 patients during hepatectomy. Total hepatic vascular exclusion (HVE) was performed on 3 patients and HVE was not used on 4 patients. The average mesohepatectomy operative time was 238 min and the average intraoperative blood loss was 480 ml (200-2,200 ml). There was no intraoperative mortality and the postoperative morbidity rate was 25% (6/24). The 1- and 3-year overall survival rates were 76 and 46%, respectively. Therefore, mesohepatectomy is a safe and effective surgical procedure for the treatment of centrally located HCC and HVE during mesohepatectomy for centrally located HCC is crucial to the success of the operation and postoperative patient recovery.

[Surgical treatment for cancer of the pancreatic head].

OBJECTIVE: To explore and evaluate the therapeutic efficacy of surgical treatment for cancer of the pancreatic head. METHODS: The clinical data of 96 patients with cancer of the pancreatic head admitted in our hospital from January 2002 to December 2009 were retrospectively analyzed. pancreatoduodenectomy was performed in 48 cases, extended pancreatoduodenectomy in 30 cases, and Roux-Y cholangiojejunostomy in 18 cases. RESULTS: The 1, 2 and 3-year survival rates were 59.2%, 41.8% and 13.2%, respectively, in the patients treated with pancreatoduodenectomy, and 73.2%, 58.2% and 24.1%, respectively, in the patients treated with extended pancreatoduodenectomy. The 1, 2 and 3-year survival rates were 36.8%, 15.8% and 5.3%, respectively, in the patients with unresectable tumor who received radiotherapy and (or) chemotherapy in Roux-Y cholangiojejunostomy. The postoperative morbidity was 29.2%, 30.0% and 27.8% in the patients treated with pancreatoduodenectomy, extended pancreatoduodenectomy and Roux-Y cholangiojejunostomy, respectively. CONCLUSIONS: Pancreatoduodenectomy is the most effective treatment. Extended pancreatoduodenectomy can improve the surgical resection rate, reduce the recurrence rate and improve the survival rate. Internal drainage is an important palliative measure.
