Manifestation of Zollinger-Ellison-Syndrome with hypovolemic shock
A 63-year-old male patient presented to a secondary hospital suffering from severe epigastric pain, vomiting and mild diarrhea for the last few hours. Since many months he experienced increasing fatigue and loss of appetite. Furthermore, recurring mild epigastric pain persisted since many years. A gastroscopy in the ambulatory setting has been unremarkable. These gastrointestinal symptoms had improved under proton-pump-inhibitor (PPI) therapy but recurred after discontinuation. Medical history revealed a diagnosis of arterial hypertension treated with lisinopril 20mg and hydrochlorothiazide 25mg, each once daily. (Source: ...

Surgical management of Zollinger-Ellison syndrome: Classical considerations and current controversies.
Abstract Zollinger-Ellison syndrome (ZES) is characterized by gastric acid hypersecretion causing severe recurrent acid-related peptic disease. Excessive secretion of gastrin can now be effectively controlled with powerful proton pump inhibitors, but surgical management to control gastrinoma itself remains controversial. Based on a thorough literature review, we design a surgical algorithm for ZES and list some significant consensus findings and recommendations: (1) For sporadic ZES, surgery should be routinely undertaken as early as possible not only for patients with a precisely localized diagnosis but also for ...

Old and New Gut Hormone, Gastrin and Acid Suppressive Therapy
Gastrin acts physiologically as a gut hormone to stimulate acid secretion after meal and as a cell-growth factor of oxyntic mucosa. Increase in serum gastrin level happens under various conditions including Zollinger-Ellison syndrome, antral G cell hyperplasia, autoimmune gastritis, atrophic gastritis, renal failure, vagotomy,Helicobacter pylori infection and acid suppressive therapy. As acid suppressive therapy causes hypergastrinemia, the association between acid suppressive therapy and gastric neuroendocrine cell tumor (NET) has been discussed during the past 30 years. In this review article, the definition of hypergast...

Prospective Evaluation of Results of Reoperation in Zollinger-Ellison Syndrome
Conclusions: These results demonstrate that a significant proportion of patients with ZES will develop resectable persistent or recurrent disease after an initial operation. These patients generally have prolonged survival after reoperation and 25% can be cured with repeat surgery, suggesting all ZES patients postresection should have systematic imaging, and if tumor recurs, advise repeat operation.

The Zollinger-Ellison syndrome: is there a role for somatostatin analogues in the treatment of the gastrinoma?
ConclusionsThe high sstr-expression in gastrinomas make them highly responsive to SSAs and support the use of such drugs to counteract the tumour growth in patients not amenable to surgical cure. Unfortunately, limited data, mainly case reports or small series, support the use of SSAs in advanced gastrinomas, therefore, it is difficult to quantify their ability to control tumour growth and disease progression.

Diagnosis and management of Zollinger-Ellison syndrome in 2017.
Authors: DE Angelis C, Cortegoso Valdivia P, Venezia L, Bruno M, Pellicano R Abstract Zollinger-Ellison Syndrome (ZES) is a clinical syndrome characterized by gastric acid hypersecretion due to the ectopic secretion of gastrin by a gastrinoma, a neuroendocrine tumor (NET) which mostly develops in the duodenum and in the pancreas. This syndrome was first described by Zollinger and Ellison in 1964; if left untreated, ZES can lead to multiple complications mainly due to gastric hypersecretion and some patients can suffer from the complications of an advanced metastatic disease. Although its clinical features are consi...

Catching the Zebra: Clinical Pearls and Pitfalls for the Successful Diagnosis of Zollinger –Ellison Syndrome
AbstractZollinger –Ellison syndrome (ZES) results from an ectopic gastrin-secreting tumor leading to peptic ulcer disease, reflux, and chronic diarrhea. While early recognition portends an excellent prognosis with>80% survival at 15 years, symptoms are often nonspecific making the diagnosis difficult to establish. Diagnosis involves a series of tests, including fasting gastrin, gastric pH, chromogranin A, and secretin stimulation. Performing these tests in the correct sequence and at the proper time is essential to avoid inac curate results. Tumor localization is equally nuanced. Although providers have clas...

The Effect of H2 Receptor Antagonist in Acid Inhibition and Its Clinical Efficacy.
Abstract The first histamine H2 receptor antagonists (H2RAs) were developed in the early 1970s. They played a dominant role in treating peptic ulcer disease and gastroesophageal reflux disease (GERD). H2RAs block the production of acid by H(+), K(+)-ATPase at the parietal cells and produce gastric luminal anacidity for varying periods. H2RAs are highly selective, and they do not affect H1 receptors. Moreover, they are not anticholinergic agents. Sequential development of H2RAs, proton pump inhibitors (PPIs), and discovery of Helicobacter pylori infection changed the paradigm of peptic ulcer disease with marked dec...

Deprescribing versus continuation of chronic proton pump inhibitor use in adults.
CONCLUSIONS: In people with mild GERD, on-demand deprescribing may lead to an increase in GI symptoms (e.g. dyspepsia, regurgitation) and probably a reduction in pill burden. There was a decline in participant satisfaction, although heterogeneity was high. There were insufficient data to make a conclusion regarding long-term benefits and harms of PPI discontinuation, although two trials (one on-demand trial and one abrupt discontinuation trial) reported endoscopic findings in their intervention groups at study end.

Assessing for multiple endocrine neoplasia type 1 in patients evaluated for Zollinger-Ellison Syndrome – clues to a safer diagnostic process
Zollinger-Ellison syndrome is a rare cause of tumoral hypergastrinemia; one out of 5 patients with this syndrome also has multiple endocrine neoplasia type 1. The diagnosis of this disease is complicated by the widespread use of proton pump inhibitors that can elevate serum gastrin levels, the cornerstone for biochemical diagnosis. Abrupt discontinuation of proton pump inhibitors could lead to adverse outcomes. Clinician awareness regarding the relationship of Zollinger Ellison syndrome and multiple endocrine neoplasia type 1, could lead to a safer diagnostic pathway.

Management of gastric and duodenal neuroendocrine tumors.
Abstract Gastrointestinal neuroendocrine tumors (GI-NETs) are rare neoplasms, like all NETs. However, the incidence of GI-NETS has been increasing in recent years. Gastric NETs (G-NETs) and duodenal NETs (D-NETs) are the common types of upper GI-NETs based on tumor location. G-NETs are classified into three distinct subgroups: type I, II, and III. Type I G-NETs, which are the most common subtype (70%-80% of all G-NETs), are associated with chronic atrophic gastritis, including autoimmune gastritis and Helicobacter pylori associated atrophic gastritis. Type II G-NETs (5%-6%) are associated with multiple endoc...

Stereoselective Pharmacodynamics and Pharmacokinetics of Proton Pump Inhibitors.
Abstract Proton pump inhibitors (PPIs) are a group of gastric acid suppressing drugs, that are strong and long-lasting inhibitors of the proton pump (referred to as acid pump antagonists). They work by irreversibly blocking the H+/K+ ATPase. PPIs are used to treat peptic ulcer disease, gastroesophageal reflux disease, nonsteroidal anti-inflammatory drug-induced gastrointestinal lesions, and Zollinger-Ellison syndrome. The structure of PPIs are similar, they all have a similar core with a sulphur atom chiral center combined with different substituent groups. In relation to the sulphur atom chiral center, the pharma...

Syndromic versus non-syndromic sporadic gastrin-producing neuroendocrine tumors of the duodenum: comparison of pathological features and biological behavior
Abstract Sporadic gastrin-producing neuroendocrine tumors of the duodenum present either with the Zollinger-Ellison syndrome (ZES) or with unspecific symptoms. While syndromic gastrin-producing neuroendocrine tumors often show metastases at the time of diagnosis, those without a syndrome do not. The aim of the study was to search for clinicopathological features that may distinguish the two categories of gastrin-producing duodenal tumors. In a retrospective study, we analyzed the clinical and pathological data in a series of 41 patients with syndromic (i.e., gastrinomas) or non-syndromic duodenal gastrin-producing...

Diagnostic and Treatment Approaches for Refractory Peptic Ulcers.
Authors: Kim HU Abstract Refractory peptic ulcers are defined as ulcers that do not heal completely after 8 to 12 weeks of standard anti-secretory drug treatment. The most common causes of refractory ulcers are persistent Helicobacter pylori infection and use of nonsteroidal anti-inflammatory drugs (NSAIDs). Simultaneous use of two or more H. pylori diagnostic methods are recommended for increased sensitivity. Serologic tests may be useful for patients currently taking proton pump inhibitors (PPIs) or for suspected false negative results, as they are not affected by PPI use. NSAID use should be discontinued when po...

Gastric Hypersecretory States: Investigation and Management
Opinion statement Hypersecretory conditions affecting the stomach account for significant morbidity and mortality manifested in some cases with peptic ulcer, gastrointestinal hemorrhage, and/or gastroesophageal reflux disease (GERD). The diagnosis of gastric acid hypersecretory states can be challenging and relies on the use of quantitative assays to measure gastric acid secretion and serum gastrin. The most common etiology for hypergastrinemia is the use of potent gastric acid inhibitors such as the proton pump inhibitors. The differential diagnosis of this condition is of critical importance, and will dictate ma...

Biochemical Testing in Patients with Neuroendocrine Tumors.
Authors: Granberg D Abstract Neuroendocrine tumors are usually slow-growing tumors. Many of these are capable of secreting peptide hormones or biogenic amines that may lead to endocrine syndromes. Nonfunctioning tumors can either secrete no hormones at all, or secrete hormones not giving rise to endocrine symptoms, such as chromogranin A, chromogranin B or pancreatic polypeptide. Chromogranin A is produced by the majority of endocrine tumors, both functioning and nonfunctioning, and is the best available marker for diagnosis, follow-up and treatment monitoring of patients with differentiated neuroendocrine tumors. ...

Somatostatin analogs for gastric carcinoids: For many, but not all.
Abstract Gastric carcinoids (GCs) are classified as: type I, related to hypergastrinemia due to chronic atrophic gastritis (CAG), type II, associated with Zollinger-Ellison syndrome in multiple endocrine neoplasia type 1, and type III, which is normogastrinemic. The management of type-I gastric carcinoids (GC1s) is still debated, because of their relatively benign course. According to the European Neuroendocrine Tumor Society guidelines endoscopic resection is indicated whenever possible; however, it is not often feasible because of the presence of a multifocal disease, large lesions, submucosal invasion or, r...
