BACKGROUND: No report has described the predictive factor of surgical difficulty for laparoscopic cholecystectomy (LC) by preoperative computed tomography (CT) findings. This study aimed to investigate whether dynamic CT findings can predict the difficulty of LC for acute cholecystitis. MATERIALS AND METHODS: Fifty-seven patients who underwent emergency LC and dynamic CT preoperatively were enrolled. Difficult LC (DLC) was defined as any patient with an operative time ≥3 h, bleeding volume ≥300 mL, common bile duct injury, partial cholecystectomy, the need for a second surgeon, and/or conversion to open surgery...

To reduce post-hepatectomy liver failure (PHLF), associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has been recently developed for patients with a limited future remnant liver (FRL). Nevertheless, high morbi-mortality rates have been reported . The current study aimed to analyze the kinetics of FRL function in patients who were offered ALPPS. Serial SPECT (99 m)Tc-mebrofenin hepatobiliary scintigraphy (HBS) was performed in all patients before and after surgery as well as at inter-stage to quantitatively assess hepatic function [total liver (TL) and FRL]...

BACKGROUND: Prognosis of gallbladder cancer (GBC) is grim even after curative surgery. Lymph node metastasis is the most important prognostic factor, but distant relapses occurring in their absence point towards additional factor. Lymph node micrometastasis could be one. The present study aimed to evaluate the incidence and clinical significance of lymph node micrometastasis. METHODS: This is a prospective study of patients undergoing curative surgery for GBC from 1 March 2013 to 30 April 2015, at our institute...

Signet ring gallbladder carcinoma is a rare aggressive variant of mucinous adenocarcinoma with poor prognosis. Positron emission tomography/computed tomography (PET/CT) with Fluor18 deoxyglucose (F18-FDG) is a useful tool in the staging of gallbladder cancer. We report a 68 years old man with a surgically resected acute cholecystitis, whose biopsy was positive for signet ring cell gallbladder carcinoma. During surgery, locoregional lymph nodes, liver or peritoneal involvement were not detected. A PET/CT was performed for staging, finding multiple hypermetabolic lytic bone lesions...

BACKGROUND: Globally, the number of people aged 80 years or over, the "oldest old," is the fastest growing population group. Because of the strong association between age and gallstone disease, both prevalence and incidence of this disease are increasing. The feasibility of the cholecystectomy in octogenarians has been evaluated in several studies that confirmed the safety of the operation. However, the safety of this procedure in nonagenarians is still controversial. The aim of this study was to evaluate the safety of cholecystectomies in nonagenarians and identify related predictors for postoperative hospital length of stay (LOS) and in-hospital mortality up to 30 days postoperatively...

Hepatocellular adenomas (HCA) are rare benign liver tumors occurring in young women taking contraception. They are associated with rare complications such as bleeding or malignant transformation into hepatocellular carcinoma. A molecular classification has divided HCA in several subgroups linked with risk factors, clinical behaviour, histological features and imaging: HNF1A inactivated HCA, Inflammatory HCA, CTNNB1 mutated HCA in exon 3, CTNNB1 mutated in exon 7 and 8 HCA, sonic hedgehog HCA and unclassified HCA...

Metastases from tumors to systemic cancers are rare. The most common intracranial recipient tumor is meningioma. Metastasis from gallbladder cancer has been previously reported from only one patient during autopsy. We present the case of a 72-year-old woman who underwent surgery for right frontal skull base meningioma.The tumor was completely removed. Histological specimens showed gallbladder carcinomatous metastasis with diffuse neuroendocrine differentiation in meningothelial meningioma. The Ki-67 proliferation index of the meningioma was 3%...

Spontaneous cholecystocutaneous fistula (SCF) is a rare complication of neglected calculous biliary disease and also an extremely rare complication of gallbladder neoplasm. This pathology has become even rarer because of prompt diagnosis and expedient surgical intervention for gallstones. So far, there is one published report of a SCF due to gallbladder adenocarcinoma. We present the case of a woman aged 87 years, admitted to the Vth Department of Surgery, Clinical Municipal Hospital of Cluj-Napoca (Romania) for a tumoral mass located in the epigastrium...

Biliary tract cancer accounts for <1% of all cancers and affects chiefly an elderly population, with predominance in men. We distinguish cholangiocarcinoma (intrahepatic, hilar and distal) and gallbladder cancer, with different pathogenesis and prognosis. The treatment is based on surgery (whenever possible), radiotherapy in selected cases, and chemotherapy. The standard cytotoxic treatment for advanced/metastatic disease is represented by the combination of gemcitabine and cisplatin, whereas fluoropyrimidines are generally administered in second line setting...
