Article: Laparoscopic Hepatic Posterior Sectionectomy: A Hand-assisted Approach.
[show abstract] [hide abstract]
ABSTRACT: BACKGROUND: Hepatic resection remains a challenging procedure in laparoscopy, requiring trained surgical teams and specialized centers.1 (-) 3 Operating on the posterior segments of the liver brings additional concerns, such as vascular control, right liver mobilization from the retroperitoneum and diaphragm, and a large transection area.1 (,) 3 (-) 6 Here we present a case of a hepatitis B-positive 42-year-old woman with a neoplastic nodule on the right posterior section of the noncirrhotic liver. METHODS: Pneumoperitoneum was made through a hand port, and three additional trocars were placed. Intrahepatic glissonian pedicle control was achieved after liver mobilization. Parenchymal transection was performed through the demarcation line between the anterior well vascularized and the posterior ischemic right segments of the liver. All surgical steps were performed with hand assistance. RESULTS: Operative time was 210 min, and estimated blood loss was 300 ml. Postoperative was uneventful. The patient was discharged on the fourth postoperative day. Histological evaluation confirmed the diagnosis of a well-differentiated hepatocellular carcinoma. The patient was free of disease after 18 months of follow-up. DISCUSSION: Our video shows a standardized operative strategy in which the hand assistance plays important role. Posterosuperior segments of the liver are still less often approached by laparoscopic surgery as a result of its limitations on visualization, mobilization, pedicle control, and parenchymal transection.1 (,) 3 (,) 6 Hand assistance helps solve these issues, making assisted resection easier than a purely laparoscopic approach and more advantageous over the open technique, providing the benefits of laparoscopy without compromising oncological safety.7.Annals of Surgical Oncology 12/2012; · 4.17 Impact Factor -
Article: Primary liver leiomyoma: a review of this unusual tumour.
[show abstract] [hide abstract]
ABSTRACT: Primary liver leiomyoma (PLL) should be considered in the differential diagnosis of liver lesions. A literature review has been completed and two cases are reported. The first is a 45-year-old white woman complaining of vague abdominal pain. She was initially evaluated with abdominal ultrasonography (US) that revealed a heterogeneous liver mass measuring 18 cm in greatest diameter. The tumour demonstrated hypointensity on T1-weighted and hyperintensity on T2-weighted magnetic resonance imaging. The second case is a 45-year-old Asian male who had undergone kidney transplantation 16 years ago for IgA glomerulonephritis and who developed mild, self-limiting epigastric pain. US showed a 4.3-cm-diameter lesion that was predominantly hypoechoic and was either compressing or arising from segment 2 of the liver. Computed tomography showed a well-circumscribed 4-cm-diameter mass that appeared to be arising from segments 2/3 of the liver and was adjacent to the anterior gastric wall. He underwent an uneventful laparoscopic left lateral sectionectomy and discharged on post-operative day 3. Pathological examination of the resection specimen confirmed the lesion as a PLL in each case. Herein, we report two cases of PLL and review the literature regarding this uncommon disorder.ANZ Journal of Surgery 09/2012; · 1.25 Impact Factor -
Article: Focal intrahepatic strictures: a review of diagnosis and management.
[show abstract] [hide abstract]
ABSTRACT: Focal intrahepatic strictures are becoming more common owing to more prevalent and accurate cross-sectional imaging. However, data relating to their management are lacking. The purpose of the present review was to synthesize the current evidence regarding these lesions and to formulate a strategy for diagnosis and management. A literature search of relevant terms was performed using Medline. References of papers were subsequently searched to obtain older literature. Focal intrahepatic strictures involve segmental hepatic ducts and/or left and right main hepatic ducts during their intrahepatic course. Most patients are asymptomatic while the minority present with vague abdominal pain or recurrent sepsis and only rarely with jaundice. Investigations used to distinguish benign from malignant aetiologies include blood tests (CEA, Ca19.9), imaging studies [ultrasonography (US), computed tomography (CT), magnetic resonance cholangiopancreatography (MRCP) and fluorodeoxyglucose-positron emission tomography (FDG-PET)], endoscopic modalities [endoscopic retrograde cholangiopancreatography (ERCP)/endoscopic ultrasound (EUS)/cholangioscopy] and tissue sampling (brush cytology/biopsy). A focal intrahepatic stricture requires thorough investigation to exclude malignancy even in patients with a history of biliary surgery, hepatolithiasis or parasitic infection. If during the investigative process a diagnosis or suspicion of malignancy is demonstrated then surgical resection should be performed. If all diagnostic modalities suggest a benign aetiology, then cholangioscopy with targeted biopsies should be performed.HPB 07/2012; 14(7):425-34. · 1.60 Impact Factor -
Article: Hepatocellular adenoma: an excellent indication for laparoscopic liver resection.
[show abstract] [hide abstract]
ABSTRACT: Laparoscopic resection for benign liver disease has gained wide acceptance in recent years and hepatocellular adenoma (HA) seems to be an appropriate indication. This study aimed to discuss diagnosis and treatment strategies, and to assess the feasibility, safety and outcomes of pure laparoscopic liver resection (LLR) in a large series of patients with HA. Of 88 patients who underwent pure LLR, 31 were identified as having HA. Diagnosis was based on radiological evaluation and resections were performed for lesions measuring >5.0 cm. The sample included 29 female and two male patients. Their mean age was 33.2 years. A total of 27 patients had a single lesion, one patient had two and one had four lesions. The two remaining patients had liver adenomatosis. Mean tumour size was 7.5 cm. Three right hepatectomies, 17 left lateral sectionectomies and 11 wedge resections or segmentectomies were performed. There was no need for blood transfusion or conversion to open surgery. Postoperative complications occurred in two patients. Mean hospital stay was 3.8 days. Hepatocellular adenoma should be regarded as an excellent indication for pure LLR. Pure LLR is safe and feasible and should be considered the standard of care for the treatment of HA when performed by surgeons with experience in liver and laparoscopic surgery.HPB 06/2012; 14(6):390-5. · 1.60 Impact Factor -
Article: Does bilioenteric anastomosis impair results of liver resection in primary intrahepatic lithiasis?
[show abstract] [hide abstract]
ABSTRACT: To evaluate the long-term results of liver resection for the treatment of primary intrahepatic lithiasis. Prognostic factors, especially the impact of bilioenteric anastomosis on recurrence of symptoms were assessed. Forty one patients with intrahepatic stones and parenchyma fibrosis/atrophy and/or biliary stenosis were submitted to liver resection. Resection was associated with a Roux-en-Y hepaticojejunostomy in all patients with bilateral stones and in those with unilateral disease and dilation of the extrahepatic biliary duct (> 2 cm). Late results and risk factors for recurrence of symptoms or stones were evaluated. There was no operative mortality. After a mean follow-up of 50.3 mo, good late results were observed in 82.9% of patients; all patients submitted to liver resection alone and 58.8% of those submitted to liver resection and hepaticojejunostomy were free of symptoms (P = 0.0006). Patients with unilateral and bilateral disease showed good late results in 94.1% and 28.6%, respectively (P < 0.001). Recurrence of symptoms in patients with hepaticojejunostomy showed that this may not be the ideal solution. Further studies are needed to establish the best treatment for patients with bilateral stones or unilateral disease and a dilated extrahepatic duct.World Journal of Gastroenterology 07/2010; 16(27):3423-6. · 2.47 Impact Factor
