New anatomical data on the drainage patterns of the uncinate process of the pancreas.

Purpose: Recently, progress has been made in the surgical management of benign pancreatic tumors sparing as much of the pancreatic parenchyma and pancreatic function as possible. However, the main complication of partial pancreatectomy is the disruption of pancreatic ducts ensuing leak of pancreatic secretion leading to the formation of pancreatic fistulae. In this study, we attempt to precisely define the anatomy of the branch duct draining the uncinate process which is of interest to the surgeons.

Long-term survival (5-20 years) after pancreatectomy for pancreatic ductal adenocarcinoma: a series of 30 patients collected from 3 institutions.

Objectives: Long-term survival after pancreatectomy for pancreatic duct adenocarcinoma has been rarely reported. Factors influencing survival are still debated. The aim of the study is to report a French multicentric series of long-term survivors after pancreatectomy for pancreatic duct adenocarcinoma.

Cystic dystrophy of the duodenal wall developing in heterotopic pancreas: report of 9 cases.

Objective: Cystic dystrophy in heterotopic pancreas (CDHP), an uncommon but serious complication of dilatation of the ectopic pancreatic ducts of heterotopic pancreatic tissue, occurs most often in the second part of the duodenum. This disorder is difficult to diagnose and raises various therapeutic questions. The aim of this study was to evaluate the most useful procedures for investigating suspected CDHP and to consider late results after surgical treatment by pancreaticoduodenectomy (PD).

[The solitary rectal ulcer syndrome].

The solitary rectal ulcer syndrome is a rare debilitating disorder of the rectum characterized by perianal chronic pain with passage of blood and mucus. The pathogenesis remains uncertain, rectal prolapse and trauma from straining are the main hypothesis. The diagnosis includes clinical symptoms associated with endoscopic lesion (erythema, ulcer or polypoïd lesion) and histological features.

[Rectal Abrikossof tumor: a rare location].

Granular cell tumors or Abrikossof tumors are neurogenous ubiquitary submucosal-like tumors that are usually benign. The most frequent locations are the skin and buccal cavity. The usual location in the digestive tract is the esophageal wall.

[Gangrene of the ligamentum teres hepatis].

Necrosis of the ligamentum teres hepatis is a very rare and misdiagnosed pathology. Four cases have been reported in the literature. Clinical symptoms with acute abdominal pain suggest peritonitis.

Intraductal papillary-mucinous tumors of the pancreas: predictive criteria of malignancy according to pathological examination of 53 cases.

Background: One of the main problems in the management and treatment of intraductal papillary-mucinous tumors is the lack of a reliable predictive factor for malignancy.

Hypothesis: Surgical treatment could be adapted to macroscopic criteria (presence of mural nodules and diameter of the pancreatic duct and of the lesion) or to tumor location (main duct, branch duct, or combined lesions) associated with benign or malignant forms.

Design: Retrospective study.

[Cystic and intraductal tumors of the pancreas].

The management of cystic and intraductal pancreatic tumours has changed over the last ten years due to increasing fortuitous discovery of incidental cystic lesions of the pancreas and better knowledge of these lesions. CT-scan or MRI can usually differentiate the two most frequent cystic tumours: benign serous cystadenoma and potentially malignant mucinous cystadenoma. Conservative management is wholly justified for serous cystadenoma without complications, whereas mucinous cystadenoma can be cured by pancreatic resection.

Elevated (> or = 10%) MIB-1 proliferative index correlates with poor outcome in gastric stromal tumor patients: a study of 35 cases.

Mitotic activity and tumor size are currently regarded as the most powerful prognostic indicators for patients with gastrointestinal stromal tumor (GIST). This retrospective study evaluated the prognostic accuracy of MIB-1 proliferative index (PI) in combination with these two indicators in 35 GIST patients. Within a high-risk group, determined initially by tumor size and mitotic count, overall survival was significantly shorter for patients whose tumors had PI > or = 10% MIB-1 positive cells.
