Clinical study for pancreatic fistula after distal pancreatectomy with mesh reinforcement.

Background: The purpose of this cohort study was to determine whether distal pancreatectomy with mesh reinforcement can reduce postoperative pancreatic fistula (POPF) rates compared with bare stapler.

Methods: In total, 51 patients underwent stapled distal pancreatectomy. Out of these, 22 patients (no mesh group) underwent distal pancreatectomy with bare stapler and 29 patients (mesh group) underwent distal pancreatectomy with mesh reinforced stapler.

The comparison of clinical results between hand suturing and mechanical stapling for gastrojejunostomy and jejunojejunostomy after SSPPD.

Background: Mechanical stapling method is widely established alternative to conventional hand suturing.

Method: For gastrointestinal anastomoses. In this study, we compare the clinical results of mechanical stapling with those of hand suturing for gastrojejunostomy and jejunojejunostomy after Subtotal Stomach Preserving Pancreaticojejunostomy (SSPPD).

Prognostic factors in gastrointestinal perforation.

Background/aims: Postoperative complications associated with gastrointestinal (GI) perforation may lead to a poor prognosis. The goal of the study was to identify factors required for the establishment of appropriate perioperative procedures in such cases.

Methodology: The subjects were 51 patients with GI perforation treated from July 2007 to June 2008 in six hospitals in the Minamikawachi district.

Thoracolithiasis: 11 cases with a calcified intrapleural loose body.

Purpose: To describe clinical and imaging characteristics of thoracolithiasis.

Materials And Methods: Medical records from our center from September 2005 to March 2007 were reviewed. A definitive diagnosis was made by multidetector-row computed tomography studies of the chest, which revealed in each patient an intrapleural calcified nodular opacity, which changed in intrapleural location on serial examinations.

The clinical results of duct-to-mucosa pancreaticojejunostomy after pancreaticoduodenectomy in consecutive 55 cases.

Objectives: Pancreatic anastomotic leakage remains a major troublesome complication after pancreaticoduodenectomy. Thus, various technical modifications regarding the pancreatic anastomosis after pancreaticoduodenectomy have been attempted to minimize anastomotic leakage. We have performed duct-to-mucosa pancreaticojejunostomy with resection of jejunal serosa (layer-to-layer pancreaticojejunostomy) and obtained extremely favorable results.

The surgical procedure and clinical results of the duct to mucosa pancreaticojejunostomies with resection of jejunal serosa.

Background: Pancreatic anastomotic leakage often results in severe complications of sepsis, intra-abdominal bleeding, pancreatic fistula, and is a significant cause of morbidity and mortality. An appropriate technique to minimize pancreatic leakage is very important. Recently we have performed duct to mucosa pancreaticojejunostomy with resection of jejunal serosa and obtained positive results.

The surgical procedure and clinical results of subtotal stomach preserving pancreaticoduodenectomy (SSPPD) in comparison with pylorus preserving pancreaticoduodenectomy (PPPD).

Background: Subtotal stomach preserving pancreaticoduodenectomy (SSPPD) is compared retrospectively with pylorus preserving pancreaticoduodenectomy (PPPD).

Methods: During 2002-2005, 21 patients (13 female, 8 male) underwent SSPPD. The mean age was 64.

Clinical results on intra-arterial adjuvant chemotherapy for prevention of liver metastasis following curative resection of pancreatic cancer.

Background: We report here the clinical results of intra-arterial adjuvant chemotherapy for the prevention of liver metastasis following curative resection of pancreatic carcinoma.

Methods: Twenty-two patients with pancreatic cancer underwent the radical operation between January 1999 and April 2005. Intra-arterial adjuvant chemotherapy with cisplatin (CDDP) and 5-fluorouracil (5FU) was selectively performed on nine patients; the remaining 13 patients did not receive chemotherapy and comprised the control group.

New method for prevention of bile leakage after hepatic resection.

Background: The usefulness of fibrin glue and bioabsorbable polyglicolic acid (PGA) felt to prevent the bile leakage was studied.

Methods: Eighty-eight patients who underwent hepatic resection without biliary reconstruction from 2001 through 2005 were studied. We divided 88 patients into 37 patients of Group A (who underwent hepatic resection between January 2001 and March 2003) and 51 patients of Group B (who underwent hepatic resection between April 2003 and January 2005).

A resected case of advanced duodenal carcinoma with occlusion of the celiac artery.

A 75-year-old woman with vomiting, admitted on March 7 2002, was diagnosed with advanced duodenal carcinoma based on ultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI), magnetic resonance cholangio-ancreatography (MRCP), percutaneus transhepatic cholangiography. Angiography showed the celiac artery to be occluded. The common hepatic artery was demonstrated via the gastroduodenal artery (GDA).

A resected case of multiple intraductal papillary mucinous tumors of the pancreas with US-guided ductal branch-oriented partial pancreatectomy.

A 69-year-old man with epigastralgia was admitted on August 26, 2002 and diagnosed with multiple intraductal papillary mucinous tumors by various imagings. The cystic tumor of pancreas head had a diameter of 2 cm, and the mural nodule of the cystic tumor measured only 3 mm. In the pancreas body the cystic tumor was measured at 1.
