Cystadenoma of the pancreas: 4 cases in our clinical experience

Cystic neoplasms account for about 10% of all cystic lesions of the pancreas and less than 1% of all exocrine pancreatic neoplasms. The authors report 4 cases of pancreatic cystadenoma (3 women and 1 man; mean age 59 years; range: 41-72), 2 serous and 2 mucinous, treated over the period from 1999 to 2002. The main symptoms were hypochondrial pain in two patients and diffuse abdominal pain in one while the fourth patient was asymptomatic. The patients were studied clinically by CT, echotomography and angiography. In three cases the tumours were located in the pancreatic body-tail, and in one case in the head. Serum amylase, lipase and tumour markers were all in the normal range. Only in one case was there an accurate preoperative diagnosis of tumour; in the other cases, a histological diagnosis was possible after surgical resection. Surgical treatment depended on tumour localisation: duodeno-cephalopancreatectomy for tumours in the head and distal pancreatectomy with splenectomy for tumours located in the body-tail, Lymphadenectomy at levels I and II was performed in all cases. There was no postoperative mortality and only one female patient developed postoperative acute pancreatitis. During the follow-up CT scans showed no recurrence of the pancreatic tumours. In agreement with the international literature, we hold that all cystic tumours of the pancreas should be treated by surgical therapy, above all because of the major differential diagnosis problems they continue to present. Conservative treatment is justified only for well documented asymptomatic serous cystadenomas.

Pancreatic endocrine tumors

Incidence of the endocrine tumors of the pancreas is about 4 to 10/1.000.000 peoples. We present 10 cases of endocrine pancreatic tumors which were operated in the First Surgical Clinic Ia?i in the last 20 years (1984-2003); these cases represent about 2.21% from all the pancreatic tumors (454 cases). It was 4 insulinoma, 2 gastrinoma, 2 gastrinoma associated with other endocrine neoplasia (Wermer syndrome) and 2 non-functioning endocrine pancreatic tumors. Female/men ratio was 9/1 and median age was about 41.9 yo (27-67 yo). In the four cases of insulinoma (all females) the diagnosis was delayed by two to five years due to misinterpretation of neurological symptoms generated by hypoglycemia. The diagnosis of insulinoma was based on Whipple triad, high plasma insulin levels associated with low plasma glucose levels, as well as the symptomatic relief after intravenous glucose injection. The surgical option was based on biological data, ultrasonography, computed tomography and arteriography. In two cases the localization of the insulinoma was established only by intraoperative ultrasonography. All tumors were localized in the tail of pancreas. In three cases we decided for a distal pancreatic resection with splenectomy and in one case for spleen preserving left pancreatectomy. Postoperative course was uneventful and all the symptoms disappeared. The diagnosis was confirmed on pathological examination in all cases. We also present two cases of gastrinoma with multiple ulcers and multiple surgical interventions for haemorrhage and perforation with peritonitis. Both patients died and diagnosis of pancreatic endocrine tumors was post-mortem. The two patients with Wermer syndrome also had ulcers complicated with haemorrhage and peritonitis and parathyroid adenoma. One case also had ante-hypophyseal and pituitary adenoma and the other had thyroid colloid hypertrophy. We performed left pancreatectomy with spleen preservation in one case and enucleation associated with total gastrectomy in the second case. The two cases of non-functioning pancreatic endocrine tumors had a non-specific symptoms. Diagnostic was established by abdominal ultrasound exam. We performed spleno-pancreatectomy in one case and pancreatectomy with spleen preservation in the other patient. Postoperative course was un-eventful.     

Cystic tumors of the pancreas: preoperative imaging,diagnosis, and treatment

The objective of this retrospective study was to explore the accuracy of preoperative diagnostic methods and the efficacy of treatment for cystic pancreatic tumors. From 1989 to 1999, 18 patients underwent surgery for cystic tumor of the pancreas, classified as follows: one serous cystadenoma, eight mucinous cystadenomas, six mucinous cystadenocarcinomas, and three nonfunctioning islet cell tumors. Computed tomography (CT), endoscopic retrograde cholangiopancreatography (ERCP), and fine needle aspiration were performed and subsequently reviewed retrospectively by two radiologists. Three patients underwent the Whipple procedure and 14 and 1 patients underwent distal and central pancreatectomy, respectively. CT showed cystic pancreatic tumors in all cases. One case was misdiagnosed as a pseudocyst. The diagnosis was accurate in 82%, 53%, 37%, and 60% of cases on CT, ERCP, and angiography, and in the cytologic analysis of the aspirated fluid, respectively. All operative procedures were performed without significant morbidity and there were no postoperative deaths. Preoperative diagnosis of cystic pancreatic tumours is imprecise. CT is the most reliable preoperative imaging method. Resection should be the treatment of choice for these lesions, except in cases of serous cystadenoma.     

Solid pseudopapillary tumor of the pancreas. A report of 3 cases and a review of the literature

Solid pseudopapillary tumours of the pancreas (SPTP) are a distinct clinico-pathological entity that differs from the other cystic pancreatic neoplasms in the young age of onset, the almost exclusive incidence in the female sex and the low degree of malignancy. SPTP is a rare neoplasm that has shown a progressive increase of incidence, passing from 0.17%-2.7% of all exocrine tumours of the pancreas in the 1980's, to 6% in recent reports in 2003. In addition, it accounts for about 5% of cystic neoplasms of the pancreas. With the present paper, in the world literature, updated to August 2005, 887 cases have been described in 248 articles. The histogenesis of these epithelial neoplasms remains uncertain though it is likely that they originate from pluripotent immature pancreatic cells. The tumour is generally of large size and invariably presents a capsule. The diagnosis in most cases is based on compressive symptoms, pain or finding of a palpable mass, while in about 20% of the patients the finding is occasional during abdominal imaging performed for other pathologies. CT and MR are not always sufficient to differentiate with certainty between this type of tumour and other cystic neoplasms of the pancreas such as pseudocysts, parasitic cysts and congenital cysts. Cytological examination in most cases permits the diagnosis of SPTP. The malignancy of these neoplasms is attenuated and local with capsular invasion, lymp-node spread and, only rarely, liver and peritoneal metastases. The surgical treatment has to be radical since the malignancy can only be defined by postoperative histological examination. The treatment consists of three possible options: duodenocephalopancreatectomy, intermediate pancreatectomy, and distal pancreatectomy with or without splenectomy. Intraoperative histological examination is mandatory for the diagnostic confirmation and for the evaluation of negativity of the pancreatic resection margins. Survival after radical resection is excellent. Moreover, in forma metastasizing to the liver an aggressive attitude may be still curative and assure longer survival. The Authors report their experience with three female patients with an average age 18 years (28,19 and 8 years) operated on between 1995 and 2000 for SPTP. Two of the patients were asymptomatic and the finding of the tumour was occasional. The third patient presented jaundice and abdominal pain. The average diameter of the tumours was 6 cm (4, 7 and 7 cm). In all three cases tumour marker values (CEA, Ca19-9, alphaFP) were normal. Only in one case was the preoperative diagnosis correct. The surgical treatment depended on the location of the neoplasms: for the two tumours in the head, in one case an enucleoresection was performed in relation to an exophytic location, while, in the other, a duodenocephalopancreatectomy was performed. In the somatopancreatic tumour a distal splenopancreatectomy was performed. Only in one case (the DCP) the capsule and the surrounding parenchyma were infiltreted by neoplasm. In all cases there was immunohistochemical positivity for alpha1-antitrypsin and for neuron-specific enolase. Neither mortality nor operative morbidity were observed. Follow-up with CT found no relapses in any of the three patients after 5, 7 and 10 years, respectively, after the operation.

Central pancreatectomy revisited

Central pancreatectomy is a surgical procedure that removes the middle segment of the pancreas and preserves the distal pancreas and spleen. This limited resection has the advantage of conserving normal, uninvolved pancreatic parenchyma, thus reducing the possibility of postoperative exocrine and endocrine dysfunction. While the incidence of postoperative endocrine insufficiency may be as low as 4%, procedural morbidity, specifically pancreatic fistula, appears to exceed the published rates for standard resections (i.e., distal/subtotal pancreatectomy or pancreaticoduodenectomy). We have reviewed our prospective pancreatic cancer database to determine the utilization of central pancreatectomy in a major cancer center with expertise in pancreatic surgery. We identified only 10 cases of central pancreatectomy over the past 13 years. Six (60%) had postoperative complications including three cases (30%) of pancreatic fistula. No patients died as a result of the procedure. At a median follow-up of 13.6 months (mean, 25.2 months), only one patient had mild endocrine insufficiency and no patients had clinically significant exocrine dysfunction. The associated morbidity of central pancreatectomy may outweigh any potential benefit in long-term pancreatic secretory function. We suggest that such a procedure be used selectively, where preservation of the pancreas appears essential.     

Middle segment pancreatectomy for the treatment of benign and low malignant potential pancreatic tumours

Background: Conventional distal pancreatectomy is used for the removal of lesions located at the body and tail of the pancreas. Generally, the spleen is sacrificed. But for benign and low malignant potential tumours in the pancreatic neck and body, this incurs notable loss of normal pancreatic tissue and the unnecessary risk of diabetes mellitus as well as splenic loss. Methods: We report three cases of middle segment pancreatectomy in an effort to avoid the unnecessary loss of normal pancreatic tissue and the spleen. Two patients were males with a mucinous cystadenoma and non‐cystic mucinous cystadenocarcinoma. The other was a female with a serous cystadenoma. Middle segment pancreatectomy was performed. Two patients were reconstructed with double pancreaticojejunostomy and the third with a pancreaticogastrostomy. Results: No major complications were observed. Comnclusions: Middle segment pancreatectomy is a safe and effective procedure for the resection of benign and low malignant potential tumours in the pancreatic neck and body with preservation of normal pancreatic tissue and the spleen in selected patients. This is the first report of middle segment pancreatectomy for pancreatic tumour in China.

Spleen-preserving laparoscopic distal pancreatectomy after division of the splenic vessels

A 37-year-old woman with a history of syncope was hospitalized with a diagnosis of hypoglycemia due to insulinoma. Computed tomography (CT) and magnetic resonance imaging revealed an enhanced solid mass, 1.5 cm in diameter, at the tail of the pancreas. Angiography via the splenic artery revealed a hypervascular mass. Because the tumor was located deep in the pancreatic parenchyma, laparoscopic distal pancreatectomy was performed. The pancreas was exposed by dissecting the greater omentum, and the tumor was located by intraoperative ultrasonography. After division of the splenic artery, the pancreas, main pancreatic duct, and splenic vein were transected with an endoscopic linear stapler. The pancreatic pedicle was divided at the splenic hilum to preserve the spleen. The postoperative course was uneventful except for the appearance of splenic infarction on a CT scan 2 weeks after surgery but without any overt symptoms. Spleen-preserving laparoscopic distal pancreatectomy by division of splenic vessels is a feasible treatment option for benign pancreatic disease.
