INTRODUCTION: The use of laparoscopic distal pancreatectomy (LDP) is increasing worldwide. It is important for surgeons to predict preoperatively the difficulty and risks of a surgery. However, very few reports have evaluated the impact of patient or tumor factors on the difficulty of LDP. We aimed to determine the predictors of technical difficulties when performing LDP. METHODS: This study included 34 patients who underwent LDP. Patient information was obtained retrospectively and included age, gender, BMI, primary disease, previous abdominal surgery, previous pancreatitis, tumor size, tumor proximity to the splenic arterial origin, type of splenic artery (SpA), operative time, blood loss, postoperative pancreatic fistula, and length of hospital stay...

Background/Aims: The role of endoscopic preoperative biliary drainage (PBD) for pancreatic head cancer is controversial because of the high incidence of stent occlusion before surgery. This study was performed to evaluate the feasibility and safety of PBD using a fully covered self-expandable metallic stent (FCSEMS). Patients and Methods: This multicenter prospective study involved 26 patients treated for pancreatic head cancer with distal bile duct obstruction from April 2011 to March 2013...

While surgery currently remains the only potentially curative treatment available for pancreatic cancer, only 20% to 30% of patients have resectable disease at diagnosis. Recently, with the introduction of intensive chemotherapy regimens such as oxaliplatin, irinotecan, fluorouracil plus leucovorin (FOLFIRINOX) and gemcitabine plus nab-paclitaxel, for the treatment of unresectable pancreatic cancer, the antitumor activity and overall survival in patients with pancreatic cancer have dramatically improved. These advances in intensive chemotherapy have led to the possibility of conversion of unresectable disease to resectable disease, and it has been reported that more than 20% of pancreatic cancer patients with unresectable locally advanced disease at diagnosis undergo successful conversion surgery after FOLFIRINOX therapy...

Curative resection is necessary to survival in pancreatic cancer, however after surgery, pathologic examination sometimes diagnoses the remains of cancer at the resected stump. Therefore, it is necessary to evaluate the stump by intraoperative rapid pathological examination. 5-aminolevulinic acid(5-ALA)is an endogenous natural amino acid and precursor of the heme pathway. 5-ALA is metabolized and accumulated as protoporphyrin IX(Pp IX)that is photosensitive substance. 5-ALA mediated photodynamic diagnosis(PDD)(ALA-PDD)has high diagnostic ability...

A 70's man underwent subtotal stomach preserving pancreatoduodenectomy(SSPPD)for pancreatic head cancer. The pathological diagnosis was adenosquamous carcinoma(ASC)of the pancreas. Two months after surgery, a recurrent tumor in the remnant pancreas was confirmed with a CT scan and suspected to be ASC by endoscopic ultrasound-guided fine needle aspiration(EUS-FNA). As the recurrent lesion was limited in the pancreas, total remnant pancreatectomy(TP)was performed 4 months after SSPPD. The final pathological diagnosis was ASC...

There is a clear consensus regarding the combined resection of organs with cancer invasion, patients with colon cancer. However, there are very few reports to our knowledge regarding the use of pancreato-duodenectomy(PD)for colon cancer patients with cancer invasion in the duodenum. We here report a colon cancer patient in whom we performed PD and right hemicolectomy, who showed favorable results with no recurrence. The patient was a 69-year-old woman. Her chief complaint was hypogastric pain. Her previous doctor performed colonoscopy and a colonoscopic biopsy, and detected a type 2 lesion, throughout the entire circumference of the transverse colon near the liver, and she was diagnosed with adenocarcinoma...

OBJECTIVE: Alternative sites to the liver for islet transplantation have been studied for a long time. Intramuscular islet transplantation appears to be an alternative site to the liver because of the ease of access. First islet autotransplantations were reported in patients after total pancreatectomies. The transplanted islets showed a proper revascularization and their function was observed for up to 2 years after the implant. However, only a few cases of autotransplantation and no allotransplantation have been performed...

Neoadjuvant therapy including chemotherapy alone or concurrent chemotherapy with external bream radiation is a standard treatment strategy for borderline resectable pancreatic adenocarcinoma and is also used routinely for primary operable cancers at some institutions (1). The use of intraoperative radiation therapy (IORT) has been limited largely because of the logistical issues in delivery of radiation during surgery (2). This is the first reported case of a borderline resectable pancreas cancer patient who underwent neoadjuvant chemo-radiation therapy followed by resection with the use of IORT using the mobile IntraBeam device to boost the resection bed and improve local control by dose escalation...

The incidence of incidentally discovered nonfunctioning pancreatic neuroendocrine tumors (PNETs) is increasing because of the widespread use of radiologic imaging studies. Due to their mostly small size, PNETs in the body and tail of the pancreas are suited for laparoscopic surgery. This video described our technique of laparoscopic distal pancreatectomy with and without preservation of spleen and splenic vessels for PNET. The decision on preservation of spleen and splenic vessels was made according to the relative location of tumors to the splenic vessels...

Pancreatic neuroendocrine tumor (PNET) is slow-growing, and account only for 2% of all pancreatic primary tumors. Surgical resection is still the only curative treatment for PNET patients. Unfortunately, most of PNETs was found with unresectable multiple liver metastases and extrahepatic metastasis as their characteristics of non-functional and asymptomatic. With advances in liver surgery in these years, especially combined associating liver partition and portal vein ligation for staged hepatectomy (ALPPS), provide a new curative surgical treatment for PNET with liver metastases patient...

Pancreatic neuroendocrine tumours (PNETs) are rare. They are generally accepted to be slow-growing and have an indolent course. These tumours can be non-functioning or functioning, consisting of a biochemically heterogeneous group of tumours including insulinomas, gastrinomas, carcinoids and glucagonomas. Although surgery remains the mainstay of treatment, controversy still exists especially for non-functioning tumours <2 cm in size. Whether these should be resected or undergo intensive surveillance remains unclear...

Pancreatic neuroendocrine tumors (pNETs) constitute a heterogenous group of malignancies with varying clinical presentation, tumor biology and prognosis. The incidence of pNETs has steadily increased during the last decades with an estimated incidence 2012 of 4.8/100,000. Recent whole genome sequencing of pNETs has demonstrated mutations in the DNA repair genes MUTYH and point mutations and gene fusions in four main pathways from chromatin remodeling, DNA damage repair, activation of mechanistic target of rapamycin (mTOR) signaling and the telomere maintenance...

Neuroendocrine tumors of the pancreas (pNETs) are a rare group of neoplasms that originate from the endocrine portion of the pancreas. Tumors that either secrete or do not secrete compounds, resulting in symptoms, can be classified as functioning and non-functioning pNETs, respectively. The prevalence of such tumors has recently increased due to the use of more sensitive imaging techniques, such as multidetector computed tomography, magnetic resonance imaging and endoscopic ultrasound. The biological behavior of pNETs varies widely from indolent, well-differentiated tumors to those that are far more aggressive...

Over the past decade, there has been increasing adoption of minimally invasive pancreatic surgery world-wide and this has naturally expanded to the management of pancreatic neuroendocrine neoplasms (PNENs). More recently, robotic pancreatic surgery (RPS) was introduced to overcome the limitations during laparoscopic pancreatic surgery (LPS). Due to the relative rarity of PNEN and the novelty of minimally invasive pancreatic surgery in particular RPS today, the evidence for robotic surgery in PNENs remains extremely limited...

Pancreatic ductal adenocarcinoma (PDA) has poor therapeutic options. Recent patient studies indicate that cholesterol-lowering statins have anti-tumor capacities. We examined several established and primary PDA and normal cell lines as well as PDA patient tissues (n = 68). We found that simvastatin inhibited viability, stemness, tumor growth and metastasis and that it enhanced the efficacy of gemcitabine. These changes were associated with modulation of Shh-related gene expression. Overexpression of Shh prevented the anti-cancer effect of simvastatin, and inhibition of Shh mimicked the simvastatin effect...

INTRODUCTION: Duplication cysts are very rare congenital malformations in adults. They are lined by gastrointestinal mucosa, connect to the digestive tract, and share smooth muscular layers and a common blood supply. In rare cases, duplication cysts are completely isolated from the digestive tract and have a proper blood supply. Completely isolated duplication cysts in the retroperitoneum are unusual so it is hard to diagnose them without a surgical resection.
