Prediction of pancreatic fistula after pancreatectomy by virtual touch tissue imaging and quantification (VTIQ) technology.

Objectives: The aim of this study was to quantitatively evaluate the stiffness of pancreatic parenchyma and solid focal pancreatic lesions (FPLs) by virtual touch tissue imaging and quantification (VTIQ) technique and to investigate the potential usefulness of VTIQ method in the prediction of post-operative pancreatic fistula (POPF) after pancreatectomy.

Methods: In this prospective study, patients who scheduled to undergo pancreatectomy were initially enrolled and received VTIQ assessment within one week before surgery. VTIQ elastography (Siemens ACUSON Sequoia, 5C-1 transducer) was used to measure the shear wave velocity (SWV) value of FPLs and the body part pancreatic parenchyma.

Laparoscopic versus open distal pancreatectomy for benign or premalignant pancreatic neoplasms: a two-center comparative study.

Objective: To compare the peri-operative outcomes for laparoscopic distal pancreatectomy (LDP) and open distal pancreatectomy (ODP) for benign or premalignant pancreatic neoplasms in two institutions.

Methods: This prospective comparative study included 91 consecutive patients who underwent LDP (n=45) or ODP (n=46) from Jan. 2010 to Dec.

Post-splenectomy intrapancreatic accessory spleen mimicking endocrine tumor of the pancreas.

Introduction: Intrapancreatic accessory spleen is an uncommon congenital abnormality of the spleen with no indication for surgical intervention. Among the few cases reported, IPAS coexisted with a normal spleen. We here report the first case of IPAS arising a couple years after splenectomy with the appearance of an endocrine tumor of the pancreas.

Long-term survival following total pancreatectomy and superior mesenteric-portal vein resection for pancreatic ductal adenocarcinoma: A case report.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer with few therapeutic options. At present, surgical resection remains the only potential curative treatment for PDAC. However, only 15-20% of patients with PDAC are eligible for lesion resection.

Clinical epidemiological analysis of the relationship between pancreatic cancer and diabetes mellitus: data from a single institution in China.

Objective: To investigate the relationship between pancreatic cancer (PC) and diabetes mellitus.

Methods: All PC patients diagnosed and treated at Zhongshan hospital from January 1991 to December 2007 were retrospectively analyzed. During this period, 770 non-digestive tract, non-neoplastic and non-hormone-related patients matched for sex and age were collected as controls.

[Clinical evaluation of 21 cases of total pancreatectomy].

Objective: To evaluate the clinical outcome of 21 cases of total pancreatectomy.

Methods: The clinical data of 21 cases of total pancreatectomy performed from April 2003 to June 2006 was retrospectively analyzed.

Results: Among the 21 patients, 1 case combined with transverse colon resection, 1 case with total gastrectomy, 9 cases with portal-superior mesentery vein resection with end-to-end anastomosis, 9 cases with portal-superior mesentery vein resection and grafts implantation, 8 cases with concomitant celiac axis resection, 4 cases with concomitant celiac axis and common hepatic artery resection, 1 case with concomitant celiac axis, portal vein and superior mesentery artery resection and reconstruction.

A series of 64 cases of pancreatic cystic neoplasia from an institutional study of China.

Aim: To recognize cystic neoplasia of the pancreas and thus to identify a panel of curable diseases.

Methods: Sixty-four cases of cystic neoplasia of the pancreas, including 28 cases of intraductal papillary mucinous neoplasia (IPMN), 12 cases of serous cystic neoplasia (SCN), 11 cases of mucinous cystic neoplasia (MCN), 11 cases of solid pseudo-papillary neoplasia (SPN), and 2 cases of solid tumor with cystic degeneration were examined immunohistochemically for their expression of MUC1, MUC2, MUC4, MUC5AC, and MUC6, as well as other related antigens.

Results: Adenoma type of IPMN and borderline lesions exhibited high expressions of MUC2, and MUC5AC.

[Clinical features and prognosis of intraductal papillary mucinous neoplasms of pancreas: analysis of 38 cases].

Objective: To explore the diagnosis, clinical manifestation, treatment, and prognosis of intraductal papillary mucinous neoplasms (IPMNs) of pancreas.

Methods: The clinical data of 38 patients with IPMNs, 23 males and 15 females, aged 64.1 +/- 10.

[Diagnosis and differential diagnosis of intraductal papillary mucinous neoplasm of pancreas].

Objective: To study the clinicopathologic features of intraductal papillary mucinous neoplasm (IPMN) and its distinction from mucinous cystic neoplasm of pancreas.

Methods: The clinical, radiologic and histologic features of 17 cases of IPMN and 13 cases of mucinous cystic neoplasm (MCN) were reviewed. Mucin profiles (MUC1, MUC2 and MUC5AC) were studied by histology (HE) and immunohistochemistry (EnVision).

Pancreatic primary lymphoma: a case report and review of the literature.

Background: Primary pancreatic lymphoma is a rare but treatable malignancy (less than 1% of pancreatic tumors) that may be clinically confused with pancreatic adenocarcinoma.

Methods: In a patient with upper abdominal pain, ultrasonography and CT detected a mass in pancreatic head, which compressed the common bile duct. The patient received a Whipple's operation and intraoperative frozen sections of the mass showed an anaplastic carcinoma.
