O liposarcoma (LPS) é um tumor mesenquimatoso maligno do tecido adiposo. A sua localização no mesentério rara. Homem, 64 anos, enviado à consulta após colonoscopia de rastreio ter revelado lipoma da parede sigmoide. Realizou Tomografia computorizada abdominopelvico (TC AP): ~ confirmou e “…no jejuno-ileal - massa sólida, suspeita GIST ou neuroendócrino”. PET-DOTANOC mostrou: “fraca expressão re...

BACKGROUND Translocating enteric bacteria play an important role in the development of infections following partial hepatectomy. The intestine itself is the first line of defence against bacterial translocation (BT). We investigated the effect of N-acetylcysteine (NAC) on BT and the intestinal wall. METHODS We compared four groups of Sprague-Dawley male rats (eight in each group): sham, sham ...

AIM To clarify the clinical factors associated with liver regeneration after major hepatectomy and the hypertrophic rate after portal vein embolization (PVE). METHODS A total of 63 patients who underwent major hepatectomy and 13 patients who underwent PVE in a tertiary care hospital between January 2012 and August 2015 were included in the analysis. We calculated the remnant liver volume foll...

Postoperative fatigue syndrome is a general complication after surgery. However, there is no ''gold standard'' for fatigue assessment due to the lack of objective biomarkers. In this study, a rodent model of postoperative fatigue syndrome based on partial hepatectomy was firstly established and serum metabonomic method based on ultra-high performance liquid chromatography coupled with Q-TOF mas...

Note Sarcomas are relatively rare malignant tumours and comprise less than 10% of all cancers. Classical classifications of sarcomas are based on the site of tumour (bone or soft tissue). Soft tissue sarcoma (STS) is the collective term used for malignancies arising in muscles, fat, vessels, the peripheral nervous system and fibrous tissue. Histopathologic examination of such tumours has reveal...

Liposarcomas are one of the most common primary lesions of the retroperitoneal region. They rarely exhibit intra-abdominal location. Because the symptoms emerge later on, they often remain unnoticed until they grow large. Our aim in this paper is to present a case of myxoid liposarcoma of descending mesocolon origin, 40 cm wide and weighing 7000 g, seen in a 47-year-old male patient. No cases a...

RATIONALE Pleomorphic liposarcoma (PLS), is a rare subtype of liposarcoma, and is considered to be of the highest malignancy grade. PATIENT CONCERNS We aimed to analyze the clinical features, diagnosis, treatment, and recurrence of the 6 cases of PLS. DIAGNOSES Six cases with confirmed pathological PLS presented at out hospital from January 2003 to January 2017. The postoperative pathology ...

BACKGROUND AND PURPOSE Liver regeneration develops after partial hepatectomy. This study investigated the enhancement of oxidative phosphorylation in liver regeneration and its correlation to mitochondrial calcium ion in rats. METHODS Respiratory functions of mitochondria isolated from regenerating rat liver 24, 48, 72, and 96 hours after 70% hepatectomy were studied including state 3 and sta...

background: a possible mechanism by which hyperthermia enhances tumor immunogenicity is the induction of nkg2d ligands on tumor cells. although the expression of mhc class i chain-related protein a and b (mica/b) has previously been reported in different carcinomas, there is no information about mica/b expression in liposarcomas. objective: to investigate mica/b induction in a human liposarcoma...

OBJECTIVE To evaluate the results of a thoracoabdominal hepatectomy and a transdiaphragmatic hepatectomy for hepatocellular carcinoma in patients with impaired liver function. DESIGN Retrospective study. SETTING A university hospital in Japan. PATIENTS Twenty-seven patients who from 1991 to 1996 underwent a thoracoabdominal hepatectomy for hepatocellular carcinoma located mainly in the su...
