Lateral hand-assistance port for Laparoscopic posterior sectionectomy

Background: The laparoscopic approach for lesion in posterosuperior location of liver is still challenging due to difficulty in traction and deep parenchymal dissection. Here we present a Case of 66-year-old female presented with abdominal pain and weight loss. CT Scan revealed a 4.4-cm lobulated cyst in liver segment6/7. Laparoscopic posterior sectionectomy with hand-assistance port at right lateral side was done. Methods: Trocars were placed. Pneumoperitoneum was made. The right hemiliver was fully mobilized. Intrahepatic posterior pedicle was controlled with the temporary inflow control of the glissonian pedicle (TICGL) technique.(1) Parenchymal dissection was proceed with ultrasonic dissector, CUSA and bipolar dissector. The hand-assistance port was made laterally. Surgeon’s left hand assisted in traction of the liver and in exposing the deeper parenchyma. The posterior pedicle was stapled. The right hepatic vein was resected. Specimen was put into a plastic bag. A Fortune drain was placed in subhepatic space and through the left lateral port. Results: The operative time was 8 hours 30 minutes. The estimated blood loss was 500 mL. No immediate postoperative complication. The drain was removed at postoperative day 5. The patient was discharged at postoperative day7. Histopathological report was lymphangioma with focal reactive change and calcification. Conclusion: Hand-assistance port can effectively assist in laparoscopic approach of posterosuperior location of liver, reducing operative time, less learning curve, while is still maintaining the benefit of laparoscopic surgery.

Pure laparoscopic posterior sectionectomy for liver metastasis resulting from choroidal malignant melanoma: A case report

Liver metastases resulting from primary choroidal malignant melanomas occur frequently and have a poor prognosis. As a result of advancements in multidisciplinary approaches, life expectancy can be increased when R0 resection is possible. Herein we report the surgical outcomes of pure laparoscopic posterior sectionectomy (PLPS) in a patient with a solitary liver metastasis resulting from choroidal malignant melanoma. The subject was a 46-year-old Japanese man who had received radiotherapy for primary right choroidal malignant melanoma 2 years before presenting at our hospital; he subsequently underwent ophthalmectomy as a result of the relapse. During follow-up, CT revealed a metastatic lesion in the liver S7, and interventional treatments were performed sequentially. The lesion still showed a tendency to enlarge, so we performed PLPS. On postoperative day 7, the patient was discharged from the hospital, and he started to receive adjuvant chemotherapy 2 weeks after PLPS. Although PLPS is deemed to be difficult for lesions in the upper part or posterior segment of the liver, we performed this modality safely.
