BACKGROUND/AIMS: There are still many important but unclear points regarding the differential diagnosis and operative indications of cystic lesions of the pancreas with malignant potential. Studies of the clinicopathological and molecular biological characteristics of such diseases are necessary. In this paper, we discuss operative indications for this condition based on a review of the literature and our own experience. METHODOLOGY: Seven cases of serous cystadenoma and 9 cases of mucinous cystadenoma or cystadenocarcinoma of the pancreas that were operated on or autopsied in our department from 1980 to 1996 were analyzed clinicopathologically. Small cystic lesions incidentally found in 300 autopsied cases were also studied. Finally, mucin-producing tumors described in several reports were reviewed, and the branch type of this tumor was especially investigated. RESULTS: A marked disappearance of pancreatic acini in the upstream pancreas was found when serous cystadenoma became large. Papillary projection was histologically found in all of the cases. Tumorous invasion to the interstitium was suspected in tumors more than 5 cm in diameter, and malignancy was reported when tumors were larger than 6 cm. As for mucinous cystadenocarcinoma, the patients had a poor prognosis. In 2 of 42 cases with a pseudocyst, small duct cell carcinoma was incidentally found adjacent to the pseudocyst on the duodenal side. With regard to branch-type intraductal papillary neoplasm, 80% of the tumors larger than 4 cm were malignant. Most of the small cystic lesions found in elderly autopsy cases were accompanied by hyperplastic epithelia without evidence of malignancy. CONCLUSIONS: Based on our experience, an operation should be considered and resection is recommended under the following circumstances: 1) cystic lesions in the body and tail of the pancreas in middle-aged women; 2) typical serous cystadenoma larger than 4 cm; 3) mucinous cystadenoma of any size; 4) branch-type intraductal papillary neoplasm larger than about 3 cm; and, 5) pseudocysts of unknown cause. Small cystic lesions in elderly patients should not necessarily be operated on, but should be followed-up carefully. 相似文献

Cystic neoplasms of the pancreas 总被引:10,自引:0,他引:10
Cystic neoplasms of the pancreas, including 4 patients with serous cystadenoma and 11 with mucinous cystic neoplasm, were studied. Serous cystadenomas composed of epithelial cells with glycogen in the cytoplasm were benign in all, whereas mucinous cystic neoplasms consisted of four benign, two borderline, and five malignant lesions. The average size was 1.8 cm in the greatest diameter in benign mucinous cystadenomas, about 5 cm in borderline tumors, and more than 8 cm in mucinous cystadenocarcinomas. Histologically, in all borderline and malignant lesions, the cysts contained areas lined with epithelium and had a benign appearance, comparable with that of mucinous cystadenoma. These observations suggest a borderline or malignant disease in the case of a benign mucinous cystadenoma. An immunohistochemical study for carcinoembryonic antigen and carbohydrate antigen 19-9 showed denser and diffuse localizations of such materials in the cytoplasm and the stroma in the case of malignant lesions, as compared to findings in borderline and benign cases. 相似文献

Aim: To report the clinicopathological features of patients with serous cystadenomas of the pancreas. Methods: Thirty-three cases of serous cystadenoma diagnosed between 1977 and 2006 were retrieved from the files of the Ohio State University Medical Center. Clinical data and microscopic slides were reviewed. Results: The patients included 27 women and 6 men with an age range of 38–83 (mean 64.3) years. The clinical presentation included 13 patients with abdominal pain and 8 patients with abdominal mass; 9 tumors were found incidentally. Abdominal CT scans in 25 patients were interpreted as suspicious for carcinoma in 8 (32%), suspicious for serous cystadenoma in 8, neoplasm not otherwise specified in 8, and suspicious for a pseudocyst in 1.Only 7 patients underwent a preoperative biopsy, and 5 of these were diagnosed as having a serous cystadenoma. All but 2 of the patients underwent surgical resection of the tumor. The serous cystadenomas varied in size from 1.0 to up to 13 cm in maximum dimension, and all but one had a multicystic appearance. Of the 33 serous cystadenomas, 20 (61%) were located in the pancreatic tail, 4 (12%) in the pancreatic body, 4 in the pancreatic body and tail, and 5 (15%) in the head of the pancreas. Follow-up in 17 patients (median 3 years, range from 1 month to 11 years) showed no recurrence of serous cystadenomas. One patient had von Hippel-Lindau syndrome, 4 patients had diabetes mellitus, 3 patients had metastatic cancer, and 2 patients had ovarian tumors. Conclusions: Serous cystadenoma is an uncommon neoplasm that can be confused with malignancy both clinically and radiologically; a correct diagnosis is important in order to provide an accurate prognosis. 相似文献

Summary A case of macrocystic serous cystadenoma of the pancreas is presented, and literature is reviewed. A 35-yr-old woman presented
with mild upper abdominal pain. Abdominal ultrasonography and an abdominal computed tomography revealed a multiloculated and
calcified cyst in the body of the pancreas. A T1-weighted image, using magnetic resonance imaging, revealed a low-intensity
mutiloculated, pancreatic mass. In contrast, T2-imaging of the tumor showed a high-intensity mass. Endoscopic retrograde cholangiopancreatography
showed no contact between the main pancreatic duct and the tumor. The preoperative diagnosis was a mucinous cystic neoplasm.
Tumor enucleation was performed. Subsequent microscopic examination of this tumor suggested the diagnosis of a macrocystic
serous cystadenoma of the pancreas. 相似文献

Benign schwannoma in the pancreatic head is very rare, with only 11 patients being reported in the English literature from a Medline search. Furthermore, only 1 of them was treated by simple enucleation. Herein, we present another enucleation case: a 71-year-old male patient with a 1.5 x 1.2-cm low-density mass, mimicking a cystic lesion located at the head of pancreas, which was detected by computed tomography. This tumor failed to be discovered by abdominal ultrasound. At laparotomy, a solid mass 1 cm in diameter was identified; it was the smallest one in the pancreatic head according to the 11 previous reported cases. No complications were found after the operation. At 10-month follow-up, the patient remains asymptomatic and has no signs of recurrence. The data of the 12 patients indicated that simple minimal invasive enucleation for small benign schwannoma in the pancreatic head was feasible and safe; early detection and early treatment of the tumor were helpful in increasing the ratio of enucleation and avoiding a very invasive Whipple operation. 相似文献

BACKGROUND/AIMS: Despite the growing interest in cystic neoplasms of the pancreas, their diagnosis, treatment and prognosis are still obscure and controversial. METHODOLOGY: We studied, from September 1989 to July 1999, 21 patients (18 women) with an average age of 54.3 years who were submitted to surgical treatment for cystic neoplasms of the pancreas. Ultrasonography and computed tomography were performed in all patients. RESULTS: The treatment performed was surgical resection: cephalic gastroduodenopancreatectomy, 4 patients; body and tail pancreatectomy, 11 patients; only tail pancreatectomy, 2 patients; and two other patients were submitted to enucleation of one small lesion in the head of the pancreas. Internal drainage, through cystogastrostomy or cystojejunostomy, was performed in 3 cases. Site of tumor: body and tail region, 14 cases; head of the pancreas, 7 cases. Three patients had postoperative complications (respiratory tract infection, surgical wound infection, abdominal abscess). Three patients developed diabetes mellitus during the late postoperative period. One patient died 45 days after surgical procedure. CONCLUSIONS: Patients who present pancreatic cystic lesions should be submitted to surgery when local and medical conditions allow it and when intraoperative frozen biopsy excludes a pancreatic pseudocyst. If the nature of the lesion cannot be determined, it is better to err resecting a pseudocyst than by leaving or draining a cystic neoplasm, since these lesions are potentially curable. 相似文献

Surgical treatment for serous cystadenoma of pancreas--segmental pancreatectomy or conventional resection? 总被引:2,自引:0,他引:2
BACKGROUND/AIMS: Benign tumors located in the neck or body of the pancreas are usually removed by left pancreatectomy or pancreaticoduodenectomy when enucleation is too risky for possible damage of the main pancreatic duct. But standard pancreatic resection has its potential operative risk and may result in loss of pancreatic parenchyme and cause impairment of pancreatic function. The aim of this study was to compare the results of segmental pancreatectomy, a limited resection of the mid-portion of the pancreas, and traditional extensive pancreatic resection, i.e. distal pancreatectomy or pancreaticoduodencetomy in patients with serous cystadenoma of the pancreas. METHODOLOGY: From January 1989 to February 2002, 19 patients with serous cystadenoma of the pancreas treated with pancreatic resection were reviewed. Among them segmental pancreatectomy was performed in 5 cases, distal pancreatectomy was carried out in 11, pancreaticoduodenectomy in 2 and total pancreatectomy in one patient. RESULTS: Operation time was significantly longer in segmental pancreatectomy than in distal pancreatectomy (P<0.001) and a greater blood loss was also noticed in the conventional resection. There was no operative mortality and the postoperative hospital stays were not different in any group. A higher rate of pancreatic fistula was encountered in segmental pancreatectomy, however all of the fistulas sealed off after conservative treatment. A trend of higher chance of developing postoperative diabetes was noticed in the conventional resection. Except for the patient who underwent total pancreatectomy no patient developed frank steatorrhea during long-term follow-up. CONCLUSIONS: Segmental pancreatectomy is a safe and technically feasible procedure in selected patients with benign pancreatic tumor. This procedure carries a similar surgical risk as that of standard operation, but avoids extensive pancreatic resection which in turn may preserve more pancreatic functions. 相似文献

Pancreatic schwannoma: Case report and an updated 30-year review of the literature yielding 47 cases
Moriya T Kimura W Hirai I Takeshita A Tezuka K Watanabe T Mizutani M Fuse A 《World journal of gastroenterology : WJG》2012,18(13):1538-1544
Pancreatic schwannomas are rare neoplasms. Authors briefly describe a 64-year-old female patient with cystic pancreatic schwannoma mimicking other cystic tumors and review the literature. Databases for PubMed were searched for English-language articles from 1980 to 2010 using a list of keywords, as well as references from review articles. Only 41 articles, including 47 cases, have been reported in the English literature. The mean age was 55.7 years (range 20-87 years), with 45% of patients being male. Mean tumor size was 6.2 cm (range 1-20 cm). Tumor location was the head (40%), head and body (6%), body (21%), body and tail (15%), tail (4%), and uncinate process (13%). Thirty-four percent of patients exhibited solid tumors and 60% of patients exhibited cystic tumors. Treatment included pancreaticoduodenectomy (32%), distal pancreatectomy (21%), enucleation (15%), unresectable (4%), refused operation (2%) and the detail of resection was not specified in 26% of patients. No patients died of disease with a mean follow-up of 15.7 mo (range 3-65 mo), although 5 (11%) patients had a malignancy. The tumor size was significantly related to malignant tumor (13.8 ± 6.2 cm for malignancy vs 5.5 ± 4.4 cm for benign, P = 0.001) and cystic formation (7.9 ± 5.9 cm for cystic tumor vs 3.9 ± 2.4 cm for solid tumor, P = 0.005). The preoperative diagnosis of pancreatic schwannoma remains difficult. Cystic pancreatic schwannomas should be considered in the differential diagnosis of cystic neoplasms and pseudocysts. In our case, intraoperative frozen section confirmed the diagnosis of a schwannoma. Simple enucleation may be adequate, if this is possible. 相似文献
