Improved Mortality, Morbidity, and Long-Term Outcome After Anatomical Hepatectomy With the Glissonean Pedicle Approach in Patients With Hepatocellular Carcinoma: 30 Years' Experience at a Single Institute.

OBJECTIVE: We evaluated the morbidity and mortality after anatomical hepatectomy with the Glissonean pedicle approach, and long-term outcomes in relation to the morbidity in patients with hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA: The mortality, morbidity, and long-term outcomes were evaluated retrospectively. METHODS: A total of 1953 patients with HCC underwent various anatomical hepatectomies with the Glissonean pedicle approach between 1985 and 2014. The mortality (30-day and 90-day) and morbidity (Clavien-Dindo class Ilia or higher) were evaluated among six 5-year eras (1985-1989, 1990-1994, 1995-1999, 2000-2004, 2005-2009, 2010-2014). RESULTS: A total of 460 patients (24%) showed morbidity, and the overall 30-day and 90-day mortality rates were 1.8% and 3.3%, respectively. The 30-day (3.9%, 3.0%, 1.8%, 1.3%, 0.3%, 0.5%: P = 0.0074) and 90-day mortality (6.0%, 4.3%, 3.8%, 2.8%, 2.2%, 1.4%: P = 0.0445) significantly improved over the eras. Blood loss >2 L (odds ratio: 11.808, P = 0.0244) was an independent risk factor for 30-day mortality, and blood loss >2 L (odds ratio: 4.046, P = 0.0271) and bile leakage (odds ratio: 2.122, P = 0.0078) were independent risk factors for 90-day mortality on multivariate analysis. Morbidity was significant independent prognostic factors for overall survival (relative risk: 2.129, P < 0.0001) and recurrence-free survival (relative risk: 1.299, P < 0.0001) in patients with HCC. CONCLUSIONS: Anatomical hepatectomy with the Glissonean pedicle approach was achieved safely in patients with HCC. For more safety and longer survival, blood loss, bile leakage, and morbidity should be reduced. Longterm outcomes after anatomical hepatectomy with the Glissonean pedicle approach in patients with HCC have been improved over 30 years with gradually less mortality and morbidity due to decreases in blood loss >2 L and bile leakage.

Debulking of giant liver hemangiomas with severe symptoms: a case report.

BACKGROUND: There are no previous reports of debulking of giant liver hemangioma. This report describes our experience with debulking surgery for a patient with bilateral giant liver hemangiomas with severe symptoms. CASE PRESENTATION: We present a case of symptomatic giant liver hemangioma in a 41-year-old woman. She presented with abdominal pain and fullness at a local hospital and underwent trans-arterial embolization (TAE). TAE was not effective, and she was not able to walk a long distance. Giant liver hemangiomas, 30 cm and 15 cm in diameter, were located in the right liver and in the left lateral section, respectively, and normal liver parenchyma with tiny liver hemangiomas was present in segment 4. The liver function was normal. However, right hemi-hepatectomy with left lateral sectionectomy was considered to be risky according to the 3DCT volumetry. Therefore, we performed right hemi-hepatectomy in order to reduce her symptoms. The postoperative course was uneventful, and she was discharged on the 14th day after surgery. The abdominal fullness and abdominal pain disappeared immediately after surgery. The hemangiomas in the remnant liver, 15 cm in diameter, showed no change, and she is well without symptoms 7 years after surgery. CONCLUSIONS: Debulking surgery is one of the options for bilateral giant liver hemangiomas with severe symptoms.

Hepatocellular carcinoma with ring calcification mimicking hydatid disease: a case report.

BACKGROUND: Ring calcification in hepatocellular carcinoma is extremely rare. Untreated hepatocellular carcinoma occasionally includes calcified lesions. Here, we report a case of ring-calcified hepatocellular carcinoma. CASE PRESENTATION: A 60-year-old man with a hepatic tumor was referred to Tokyo Women's Medical University Hospital. He had a history of chronic hepatitis C. Computed tomography showed a liver tumor 20 mm in diameter in segment 6 of the Couinaud classification, with ring calcification. Based on this uncommon imaging presentation and the patient's past exposure to the definitive hosts of Echinococcus multilocularis, he was preoperatively diagnosed with echinococcosis. Partial hepatectomy was performed as a radical treatment for echinococcosis. A final diagnosis of hepatocellular carcinoma was confirmed based on pathological findings. The patient was discharged uneventfully. CONCLUSION: The presentation of an extremely rare hepatocellular carcinoma with ring calcification may be disguised as hydatid disease.

[A Case of Unresectable Pancreas Cancer with 32 Months Survival after Chemotherapy].

We report a case of unresectable pancreas cancer. A 70-year-old woman presented with worsening diabetes and serum CA19-9 elevation. A tumor with portal vein and supra-mesenteric vein invasion was observed by computed tomography. She was diagnosed with unresectable pancreas head cancer that was locally advanced. Chemotherapy was administered with gemcitabine and nab-paclitaxel for 19 courses, followed by gemcitabine alone for 4 courses. After the addition of 6 courses of chemotherapy, a 60%dose of chemotherapy was administered for 13 courses due to severe neutropenia. The patient died 32 months after the first visit. The 60% dose of gemcitabine and nab-paclitaxel also inhibited tumor growth. These findings suggest the effective and safe long-term use of gemcitabine and nab-paclitaxel.
