Surgical treatment of pancreatic insulinomas in the era of laparoscopy   总被引:6,自引:4,他引:2  
Lo CY  Chan WF  Lo CM  Fan ST  Tam PK 《Surgical endoscopy》2004,18(2):297-302
Background: Laparoscopic resection has been increasingly reported for pancreatic insulinomas. This report evaluates our experience with surgical treatment for pancreatic insulinomas in this era of laparoscopy and reviews the application, safety, and outcome of this surgical approach reported in the literature. Methods: In a consecutive series of 10 patients with pancreatic insulinomas, laparoscopic resection was performed for selected patients after routine preoperative localizations. The outcome of this operative strategy was reviewed together with reported cases involving laparoscopic resection of pancreatic insulinomas. Results: Laparoscopic distal pancreatectomy or enucleation was performed for four patients with tumors located at the body or tail of the pancreas, whereas open enucleation was performed for six patients with tumors located at the pancreatic head. Pancreatic leak developed in one laparoscopic and two open enucleations. A review of reported cases in the literature showed that 61 of 69 attempted laparoscopic pancreatic resections for insulinomas were performed successfully. All except two tumors were located at the body or tail of the pancreas. For 42 cases with detailed information, 41 tumors at the pancreas body or tail were removed successfully by enucleation (n = 24) or distal pancreatic resection (n = 17), and one tumor at the pancreatic head was enucleated successfully. Pancreatic fistula, the most frequent complication, occurred in 8 (19%) of 42 laparoscopic resections. Conclusions: Laparoscopic resection of pancreatic insulinomas is safe and feasible for tumors located at the body or tail of the pancreas. Its application for tumors located at the pancreatic head needs further evaluation.  相似文献

Neuroendocrine carcinomas of the pancreas with 'Rhabdoid' features   总被引:1,自引:0,他引:1  
Neuroendocrine carcinomas of the pancreas are rare neoplasms whose morphologic features generally mirror those seen in neuroendocrine tumors in other organs. Rarely, however, they may display unusual morphologic appearances that can introduce difficulties for diagnosis. We report four cases of primary neuroendocrine carcinomas of the pancreas (islet cell tumors) that were characterized by prominent "rhabdoid" features of the tumor cells. The lesions occurred in two men and two women 37-79 years of age who presented with symptoms of biliary obstruction and epigastric pain; one patient had recurrent gastric ulcers and an elevated gastrin level. The tumors were located in the head and tail of the pancreas and measured 2.5-4.5 cm in greatest diameter. Histologic examination revealed sheets of monotonous tumor cells with uniform round nuclei showing dispersed chromatin and containing abundant densely eosinophilic cytoplasmic inclusions that displaced the nuclei toward the periphery. In all cases, the rhabdoid elements appeared to merge with areas showing a more conventional neuroendocrine morphology. Immunohistochemical studies in all cases showed strong cytoplasmic positivity of the rhabdoid tumor cells for chromogranin, synaptophysin, and cytokeratin. Recognition of this unusual morphologic appearance is of importance to avoid mistaking these lesions for other types of malignant neoplasm.  相似文献

Background Neuroendocrine tumors of the pancreas are rare tumors. We identified predictive factors that are associated with long-term survival (≥5 years). Methods Fifty patients with a diagnosis of neuroendocrine tumors of the pancreas were retrospectively evaluated. The following factors were evaluated for disease-specific mortality: age, sex, primary tumor location, functional status, type of primary tumor treatment, presence or absence of liver metastases, timing of liver metastases occurrence, and type of liver metastases treatment. Aggressive treatment of the liver metastases included surgery, chemoembolization, or intrahepatic arterial infusion chemotherapy. Results Twenty-three patients (47%) had tumor located in the head of the pancreas, and 29 patients (58%) had nonfunctioning tumor. Thirty-nine patients (78%) had liver metastases. The median follow-up for the entire group was 35 months (range, 76–206 months). The median survival for the entire group was 40 months, and the overall 1-, 2-, and 5-year survival rates were 84%, 69%, and 36%, respectively. Factors that had a significant favorable effect on survival included curative resection of the primary tumor, metachronous liver metastases, absence of liver metastases, and aggressive treatment of the liver metastases. Conclusions Definitive surgical resection of the primary tumor, absence of liver metastases, metachronous liver metastases, and aggressive treatment of the liver metastases were predictors of long-term survival in patients with neuroendocrine tumors of the pancreas.

Among 142 patients with islet cell tumor who were admitted to hospital between 1982 and 1999, 15 patients (10.6%) had malignant tumours. The mean age was 45.3 +/- 5.8 years. Islet cell tumors were located in the head and corpus of the pancreas in 26.6% and 26.6% of the patients, respectively, in the tail of the pancreas in 46.8% of the patients. The mean size of the tumor was 2.9 +/- 0.7 cm, in 6 patients (40%) liver metastases were found. US, CT and angiography which sensitivity were 72.7, 100 and 85.7%, respectively, were used for topical diagnosis of the islet cell tumors. 12 patients were operated on (15 operations) and 3 patients were treated conservatively by streptozocin. Surgical procedures included distal pancreatic resection (n = 11), enucleation of the tumor (n = 2), hepatic resection (n = 1), abdominal exploration (n = 1). In 2 patients palliative pancreatic resections were combined with transarterial embolization and devascularisation of the liver metastases and 2 patients were treated by systemic chemotherapy. To reveal malignancy before and during the operation was possible only by evaluation of distant metastases and the adjacent organs infiltration. In other cases to determine the diagnosis was possible only after planned histological identification of the resected specimens. 5-year survival rates after conservative and surgical treatment were 33% and 62.5%, respectively. In patients without distant metastases 5-year survival rate was 100%.  相似文献

Data of 111 patients with ductal carcinoma of the pancreas examined over a decade (1979-1989) at the 1st Department of Surgery, "La Sapienza" University of Rome, are presented. 21.6% of them underwent pancreatic resection and 40.5% biliodigestive diversion. Resectability was 26.5% for tumors of the head, 11.8% for tumors of the body and tail, nil for diffuse tumors. Overall operative mortality was 13.5%. Only stage I patients were shown to be resectable for cure and benefited from surgery with 21% probability of 5-year survival.  相似文献

OBJECTIVE: Laparoscopy is a safe, feasible technique for benign pancreatic pathologies and has been increasingly reported for neuroendocrine tumors located at the body and tail of the pancreas. We report a case of successful enucleation of a nonfunctioning neuroendocrine tumor located at the head of the pancreas, in a patient with multiple endocrine neoplasia type I. METHODS: A 5-cm nonfunctioning neuroendocrine tumor at the pancreatic head was identified by computerized tomography scan. Laparoscopic ultrasound did not reveal additional tumors on any other part of the pancreas. RESULTS: Enucleation was successfully performed for this solitary tumor because of its favorable position. Histology revealed an islet cell tumor. No postoperative complications occurred and recovery was rapid. CONCLUSION: Laparoscopic enucleation of neuroendocrine tumor at the pancreatic head is safe and feasible for select patients.  相似文献

Solid and papillary epithelial neoplasms of the pancreas (SPENP) are extremely rare and usually affect young women. We retrospectively reviewed our experience with pancreatic neoplasms from 1986 to the present and identified nine patients with SPENP. All nine patients were female with a mean age of 32 years (range 16-66). All patients presented with gastrointestinal complaints including pain, mass, dyspepsia, or bloating and were subsequently diagnosed with a tumor of the pancreas by CT scan. All patients underwent surgical resection. Two patients had tumors located in the head of the pancreas and underwent a pancreaticoduodenectomy. The remainder had tumors located in the tail of the pancreas and underwent distal pancreatectomy. Pathology demonstrated solid and papillary or solid and cystic pseudopapillary neoplasm of the pancreas. Three tumors were positive for both vimentin and alpha-1 antitrypsin on immunohistochemical studies, and three were positive for neuron-specific enolase. All nine patients underwent curative resection and are alive without any evidence of recurrence with a mean follow-up of 5.4 years. SPENP is considered to be a low-grade malignancy with an excellent prognosis. Prompt diagnosis and surgical resection can result in cure.  相似文献

Preoperative staging and assessment of resectability of pancreatic cancer   总被引:20,自引:0,他引:20  
To study the accuracy of preoperative staging techniques for assessing resectability of pancreatic and ampullary adenocarcinoma, we entered 88 consecutive candidates into a prospective study of contrast-enhanced computed tomography, magnetic resonance imaging, angiography, and laparoscopy. Resectability was proved in 16 (29%) of 55 patients for the head of the pancreas, 1 (6%) of 17 for the body and tail of the pancreas, and 14 (88%) of 16 for the ampulla. The combined findings of computed tomography and angiography showed that more than 87% of pancreatic head tumors were unresectable because of vascular encasement, but neither modality sufficed alone. Small liver and peritoneal metastases were found in 15 (27%) of 55 cancers of the head of the pancreas, 11 (65%) of 17 cancers of the body and tail of the pancreas, and 1 (6%) of 16 cancers of the ampulla; computed tomography missed all but 2 of these instances of metastasis, but laparoscopy with biopsy identified 22 (96%) of 23 instances. Magnetic resonance imaging findings did not differ significantly from computed tomography and conferred no added benefit. Ninety percent of unresectable tumors were identified. Seventy-eight percent of pancreatic head cancers were resectable when all test results were negative vs 5% (2/37) when any test result was positive. This study demonstrates that accurate and efficient triage is possible for patients with cancer of the pancreas and ampulla.  相似文献

Mucin-producing tumors (MPTs) of the pancreas are increasingly being recognized. To evaluate the appropriate surgical treatment and predict the prognosis of MPTs, we performed a retrospective clinicopathological study in 51 patients, 27 with benign tumors and 24 with borderline/malignant tumors. Three of the malignant tumors showed stromal invasion and lymph node metastasis on histological examination. Of the 24 patients with borderline/malignant tumors, 2 died of MPTs and 4 died of other diseases. At the last follow-up, 35 patients were alive and well. The 5-year postoperative survival rate was 90% for patients with benign tumors, and 78% of these with borderline/malignant tumors. Five of the patients with borderline/malignant tumors had multicentric tumors. Three of these patients underwent resection of the rest of the pancreas, 5, 6, and 8 years, respectively, after the first operation. Extended radical resection is required for malignant MPT with invasion of the pancreatic stroma. We prefer to perform pancreatogastrostomy or Imanaga's procedure to allow examination of the body and tail of the pancreas by endoscopic retrograde pancreatography after resection of the pancreatic head. Careful follow-up for a long period may be the most prudent approach for detecting multiple MPTs in the residual pancreas after surgical treatment.

Mucinous cystic neoplasms (MCN) of the pancreas are rare tumors that are almost exclusively located in the body or the tail of the pancreas. A 60-year-old woman with no history of pancreatic disease was referred to our hospital with a chief complaint of dull pain in the upper abdomen. Abdominal computed tomography showed a multilocular cystic mass of 7.0 cm in the head of the pancreas, and endoscopic retrograde cholangiopancreatography showed no communication between the cystic mass and the main pancreatic duct. A pancreatoduodenectomy was performed for the complete resection of the tumor, and an annular pancreas was discovered by accident. The pathological examination of the tumor led to a definitive diagnosis of MCN with ovarian-type stroma. To our knowledge this is the first documented case of MCN occurring in the head of the pancreas and associated with annular pancreas.  相似文献
