Sporadic Zes
An experienced surgeon can find gastrinoma in almost every patient 98 and nearly one-half 46 are cured a rate similar to imaging positive tumor patients. Pancreatic gastrinomas should be enucleated if located 3 mm or farther from the main pancreatic duct.

A high index of clinical awareness is necessary to correctly diagnose ZES.
Sporadic zes. Sporadic ZES in a 54-year-old woman. The diagnosis of ZES is delayed 3-5 years from its onset and is delayed as long as in sporadic ZES cases. Aggressive growth is associated with a decreased ten-year survival 30 compared to the excellent survival in those with nonaggressive disease 10 yr-survival96.
Advances in radiological imaging angiography and endo-. An experienced surgeon can find gastrinoma in almost every patient 98 and nearly one half 46 are cured a rate similar to patients with positive imaging findings. In 75 of cases ZES is sporadic or random whereas in 25 it is associated with MEN 1 an inherited condition characterized by pancreatic endocrine tumors pituitary tumors and hyperparathyroidism.
ZES occurred before age 40 years in 50-60 of the current patients in contrast to older studies. Conversely lesions that are closer to the pancreatic duct require distal pancreatectomy with or without splenectomy. To control the hypersecretion of gastric acid and to.
Duodenal gastrinomas in patients with sporadic ZES are frequently small most commonly located in the proximal duodenum and associated with regional lymph node metastases in 60. Long-term prognosis is good. Patients with multiple endocrine neoplasia Type I MEN-I and ZES become symptomatic at an earlier age than patients with sporadic ZES.
Zollinger-Ellison syndrome is a condition caused by gastrin-producing neuroendocrine tumour that causes gastric acid hypersecretion and peptic ulcer disease. Patients with multiple endocrine neoplasia Type I MEN-I and ZES become symptomatic at an earlier age than patients with sporadic ZES. A series of 123 patients showed an immediate postoperative cure.
Gastrinomas in these locations especially the duodenum can be small. Download Table Sporadic and MEN-1-associated ZES from publication. Can be sporadic or associated with multiple endocrine neoplasia syndrome type 1.
Sporadic ZES patients with negative imaging studies are not rare even in the post-SRS period. Primary and reoperative surgery in patients with sporadic ZES results in a significant rate of biochemical cure In selected patients with recurrent or persistent disease reoperation for resection of gastrinoma is associated with excellent longterm survival and is warranted. Gastrinomas are found in the duodenum in more than 60 of patients with sporadic ZES and in more than 85 with MEN1-associated ZES.
Disease-free survival is lower for patients with regional lymph node metastases suggesting that a more systematic lympha. While the latter is usually treated with acid suppression alone sporadic gastrinomas are. Observed that some cases of ZES were decidedly sporadic whereas others occurred in constellation with other clinical features that comprised what we now understand to be a genetic syndrome that later became known as MEN-1 4.
In sporadic ZES the goal of surgery is to cure the disease. Multiple endocrinopathies are common but are rarely diagnosed synchronously mandating life-long surveillance for patients with ZES. This is recommended because high-cure rates have been demonstrated in patients with sporadic ZES.
ZES should be considered in the differential diagnoses of patients who present with abdominal pain malabsorption and chronic watery diarrhea. In sporadic ZES gastrinomas are known to occasionally occur in the liver. However ZES was rarely 8 the only initial manifestation of MEN1 if careful testing was done.
The second most common location is the pancreas the. Patients with ZES have elevated fasting serum gastrin concentrations 100 pgml and basal gastric acid hypersecretion 15 mEqh. The secretin stimulation test is the best test to distinguish ZES from other.
Surgical cure is rare. Sporadic ZES Case 1 A 54-year-old woman presented with a 6-year history of peptic ulcer disease consisting of abdominal pain and upper gastroin- testinal GI bleeding. In ZES patients without MEN1sporadic ZES 25 of their gastrinomas show aggressive growth behavior 6970.
Patients with MEN-I syndrome in which ZES was a compo- nent. Because liver metastases were found i. Zollinger-Ellison syndrome ZES is characterized by severe recurrent peptic disease and hypersecretion of gastric acid resulting from gastrinomasApproximately 75 of gastrinomas are sporadic and 25 of patients have multiple endocrine neoplasia type 1 MEN1There are two therapeutic goals in patients with ZES.
All patients with a biochemical diagnosis of sporadic ZES should undergo surgical exploration. Some people with Zollinger-Ellison syndrome may go undiagnosed as the disorder is rare and its cause is not clear. Most individuals with MEN-1 develop hyperparathyroidism or excessive secretion of parathyroid hormone resulting in increased calcium blood levels.
These findings suggest that surgery should be performed as soon as possible in sporadic ZES despite negative imaging findings. Alternatively severe diarrhea may be the only presenting symptom. Common presentation includes refractory peptic ulcer disea.
Associated symptoms may include kidneys tones bone abnormalities andor. In patients with sporadic ZES but not in those with multiple endocrine neoplasia type 1 MEN-1 and ZES there was a significant relationship between the level of initial FSG and tumor size and location of primary tumor frequency of lymph node and liver metastases and survival. Declaration of Helsinki31 The ZES was diagnosed as described previously32 The presence of sporadic ZES was established by the lack of a family or personal history suggestive of MEN1 and by no evidence of parathyroid disease pituitary disease or other functional pancreatic endocrine tumors33 Methods On their initial admission patients.
Approximately two-thirds of patients have sporadic ZES while the rest is part of multiple endocrine neoplasia type 1. Survival is longer for patients with ZES and MEN compared with patients with sporadic ZES. Individuals with ZES in association with MEN-1 may tend to develop symptoms at an earlier age than those with sporadic ZES.
Treatment of ZES depends on whether the gastrinoma is sporadic or part of the inherited MEN I syndrome. Patients with ZES have elevated fasting serum gastrin concentrations 100 pgml and basal gastric acid hypersecretion 15 mEqh. Imaging negative sporadic ZES patients are not rare even in the post-SRS period.
