Gastrointestinal bleeding as initial presentation of extramedullary plasma cell neoplasms: A case report and review of the literature.

Background: Plasma-cell neoplasms rarely involve the gastrointestinal tract and manifest as gastrointestinal bleeding. Plasmablastic myeloma is an aggressive plasma cell neoplasm associated with poor outcomes. A small number of cases with gastrointestinal involvement is reported in the literature and therefore high index of suspicion is essential for avoiding delays in diagnosis and treatment.

Lymphoepithelial Cyst of the Pancreas.

Lymphoepithelial cyst (LEC) of the pancreas is an extremely rare, benign pancreatic cystic lesion that is difficult to differentiate preoperatively from other cystic pancreatic lesions. LEC may have malignant potential. Here, we describe a case of LEC of the pancreas - initially suspected to be a mucinous cyst neoplasm - in an elderly man presenting with abdominal pain, who went on to have a distal pancreatectomy and splenectomy.

Surgery remains the best option for the management of pain in patients with chronic pancreatitis: A systematic review and meta-analysis.

Controversy related to endoscopic or surgical management of pain in patients with chronic pancreatitis remains. Despite improvement in endoscopic treatments, surgery remains the best option for pain management in these patients.

Reduced dissemination of circulating tumor cells with no-touch isolation surgical technique in patients with pancreatic cancer.

Circulating tumor cells (CTCs) disseminate from the primary tumor and travel through the bloodstream and lymphatic system. The detection of and/or increase in the number of CTCs during a patient’s clinical course may be a harbinger of forthcoming overt metastasis. We aimed to examine the impact of 2 different surgical techniques, standard (ST) pancreaticoduodenectomy (PD) and no-touch isolation (NT) PD, on tumor behavior and outcome in patients with pancreatic cancer by using CTCs as biomarkers.

Preoperative superselective mesenteric angiography and methylene blue injection for localization of obscure gastrointestinal bleeding.

Localizing obscure gastrointestinal bleeding can be a clinical challenge, despite the availability of various endoscopic, imaging, and visceral angiographic techniques. We reviewed the management of patients presenting with obscure gastrointestinal bleeding during the period from 2005 to 2011. Four patients had preoperative localization of the bleeding site with superselective mesenteric angiography, which was confirmed by the use of intraoperative methylene blue injection.

Laparoscopic resection of a giant exophytic liver haemangioma with the laparoscopic Habib 4× radiofrequency device.

Haemangiomas are the most common solitary benign neoplasm of the liver with an incidence ranging from 5% to 20%. Although usually small and asymptomatic, they may reach considerable proportions and rarely give rise to life-threatening complications. Surgical intervention is required for incapacitating symptoms, established complications, and diagnostic uncertainty.

Percutaneous intraductal radiofrequency ablation is a safe treatment for malignant biliary obstruction: feasibility and early results.

Purpose: Previous clinical studies have shown the safety and efficacy of this novel radiofrequency ablation catheter when used for endoscopic palliative procedures. We report a retrospective study with the results of first in man percutaneous intraductal radiofrequency ablation in patients with malignant biliary obstruction.

Methods: Thirty-nine patients with inoperable malignant biliary obstruction were included.

Tumor infiltration in the medial resection margin predicts survival after pancreaticoduodenectomy for pancreatic ductal adenocarcinoma.

Background: Microscopic tumor involvement (R1) in different surgical resection margins after pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC) has been debated.

Methods: Clinico-pathological data for 258 patients who underwent PD between 2001 and 2010 were retrieved from a prospective database. The rates of R1 resection in the circumferential resection margin (pancreatic transection, medial, posterior, and anterior surfaces) and their prognostic influence on survival were assessed.

Isolated laparoscopic caudate lobe resection.

The local anatomy of the caudate lobe of the liver, between the hepatic hilum and the inferior vena cava, presents a surgical challenge when an isolated resection is attempted. The video of the laparoscopic technique is presented in a 20-year-old woman with a 60 × 40 mm lesion.

18F-fluorodeoxyglucose positron emission tomography in management of pancreatic cystic tumors.

Objectives: To evaluate the effectiveness of PET in differentiating malignant from benign pancreatic cystic tumors.

Methods: Between 2009 and 2010, all patients with pancreatic cystic tumors who had PET, triple phase contrast computed tomography (CT) and endoscopic ultrasound (EUS) were reviewed. Clinicopathological characteristics and final histology were correlated with preoperative PET, CT and EUS to assess the value of each modality in detecting malignant from benign lesions for clinical decision-making.

Loco-recurrence after resection for ductal adenocarcinoma of the pancreas: predictors and implications for adjuvant chemoradiotherapy.

Purpose: Loco (regional)-recurrence rate after pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC) remains high, and the efficiency of adjuvant chemoradiotherapy is still debated. We aimed to assess predictors of loco-recurrence in order to tailor the indications for adjuvant chemoradiotherapy.

Methods: Patients who underwent PD for PDAC between January 2001 and December 2010 were retrieved from a prospective database.

Radiofrequency-assisted hepatic resection.

Background: The only curative procedure to date for liver tumors is surgical resection, which remains a major procedure with marked morbidity and mortality. Radiofrequency (RF) has increasingly been used for both ablation and resection. On the basis of this technique, a new bipolar RF device, Habib 4X, has been developed and used clinically.

En bloc resection of the pancreatic head and second part of duodenum for a duodenal gastrointestinal stromal tumor: a multi-media report.

Duodenal gastrointestinal stromal tumors are rare tumors. When these tumors arise from the second part of the duodenum they can easily be misdiagnosed as a pancreatic head cancer. A case of a 37-year-old female presenting with a one-year history of right upper quadrant pain is described here, who was subsequently found to have a mass in the head of the pancreas.
