Dumping syndrome in children.

Dumping syndrome developed in seven children after gastric surgery, (Nissen fundoplication in six, Whipple procedure in one). The patients ranged from age 10 months to 13 years, and four of the seven were neurologically impaired. The diagnosis was made by demonstrating an abnormal response to an orally administered glucose challenge. The pediatric literature records only eight cases, but we believe that dumping syndrome is more common in children than once believed. Dietary management can often dramatically diminish the associated symptoms.

Measurement of superior mesenteric artery flow by means of Doppler ultrasound in early dumping syndrome.

OBJECTIVE: Dumping occurs in about 10% of patients after gastric surgery. It has been suggested that early dumping is associated with an abnormal increase in postprandial splanchnic flow, but data from controlled studies are lacking. Therefore we have studied basal and postprandial superior mesenteric artery (SMA) blood flow in patients with dumping and in two control groups. METHODS: Three groups were studied, one group of patients after gastric surgery with early dumping (n = 6), one surgical control group with patients after gastric surgery without dumping symptoms (n = 7), and a healthy control group without previous gastric surgery (n = 10). Blood glucose and heart rate were measured after dumping provocation by oral ingestion of 50 g glucose. SMA blood flow was measured both basally and 20 min after glucose ingestion. RESULTS: Basal SMA flow was similar in the three groups. After glucose ingestion SMA flow was not significantly different between dumping patients and surgical controls. However, stimulated SMA flow in both groups after gastric surgery combined was significantly (p < 0.05) higher than in healthy controls. CONCLUSION: The systemic symptoms associated with early dumping do not result from increased SMA blood flow per se. After gastric surgery patients have an increased postprandial SMA flow irrespective of the presence of dumping.

Dumping syndrome after Nissen fundoplication.

Dumping syndrome is infrequently reported in children, but has significant morbidity. It may be difficult both to diagnose and manage. Two children are reported who developed dumping syndrome after Nissen fundoplication. Symptoms occurred soon after the operation and included post-prandial pallor, sweating, lethargy and diarrhoea. Failure to thrive was a prominent feature. Typical biochemical changes included hyperglycaemia shortly after meals, followed by hyperinsulinaemia and reactive hypoglycaemia. Effective treatment was only achieved with continuous enteral feeding. Children undergoing fundoplication should be closely monitored for episodes of hypoglycaemia and unresponsiveness. The incidence of dumping syndrome after fundoplication may be underestimated, particularly in children.

[The effect of alpha-glucosidase inhibitor on burning epigastralgia in dumping syndrome: a case report].

Dumping syndrome results from a rapid passage of carbohydrate in the small intestine after gastric surgery. A 50-year-old man developed the syndrome after surgery for peptic ulcer. He often complained of burning epigastralgia after meals. Various methods of treatment had only a limited effect. Acarbose, alpha-glucosidase inhibitor, suppresses the breakdown of carbohydrates in the small intestine and consequently reduced osmolarity. The patient had a dramatic improvement in the dumping syndrome including epigastralgia, diarrhea and perspiration with an administration of acarbose 50 mg. There was no intractable side effect. Preprandial administration of acarbose is a reasonable treatment in the case of dumping syndrome.

[Pathogenesis, diagnosis and therapy of the dumping syndrome].

The dumping-syndrome is a severe complication of gastric surgery after operations which destroy or weaken the sphincter mechanism of the pylorus. The pathogenesis involves the release of kinins, the triggering of neurogen reflex mechanisms by distending the jejunum, the massive flow of fluid in jejunal lumen, the loss of the reservoir function of the stomach, and, possibly, the pathologic release of gastrointestinal hormones. Preoperatively, intensive diagnostic efforts are necessary, which must include a psychiatric check-up. For surgical treatment several modifications of reversal operations from Billroth II to Billroth I with reconstruction of duodenal passage have been developed. Our own modification includes, beside testitution of the duodenal passage, the construction of a gastric pouch.

Efficacy of guar gum in preventing the dumping syndrome.

The occurrence of dumping symptoms during 1 wk of use of 5 g of guar gum or placebo in meals was examined in a double-blind study in 11 patients, who had undergone gastric resection and were suffering from the dumping syndrome. The results show that guar gum prevented the dumping syndrome and increased tolerance to foods not previously tolerated in nine of the 11 patients.

Insulinoma misdiagnosed as dumping syndrome after bariatric surgery.

BACKGROUND: Late dumping syndrome is a possible side-effect of gastric bypass. Hypoglycemic symptoms may develop 3-4 hours after certain types of foods. There may exist patients, however, who present hypoglycemia in the absence of dumping syndrome. The presence of only mild symptoms of hypoglycemia may make the evaluation of these patients difficult and delay the identification of other possible sources of hyperinsulinemia, including an insulinoma. CASE REPORT: A 65-year-old woman underwent gastric bypass for continued weight gain and morbid obesity. After surgery, the patient had repeated episodes of hypoglycemia, diagnosed at follow-up as late dumping syndrome. The persistence of hypoglycemic episodes after nutritional counseling and modifications in the feeding pattern led to consideration of an autonomous source of hyperinsulinemia, and MRI and CT identified insulinoma. After a laparotomy and pancreatic tumor resection, she remains free of symptoms. CONCLUSION: Hypoglycemic episodes after obesity surgery are not always related to dumping syndrome. The persistence of hypoglycemia in spite of nutritional counseling should raise the possibility that there may exist other causes. Insulinoma, the most common cause of endogenous hyperinsulinemia, should be investigated in these patients, since it is a tumor that can be cured.

The early postprandial dumping syndrome: prevention and treatment.

The early postprandial dumping syndrome can be prevented or minimized by the appropriate selection of the operative procedure to fit the patient and the peptic ulcer problem he presents, and by proper attention to diet in the early postoperative period. When it does occur, the syndrome usually responds favorably to dietary management and tends to spontaneously regress in severity with time. For these reasons further surgery is seldom required for the early postprandial dumping syndrome. In the patient who fails to improve with diet therapy and time and has disabling symptoms often accompanied by progressive malnutrition, revisional surgery should be undertaken. It is the objective of the surgeon to alter the reconstruction in such a way that emptying from the stomach or gastric remnant is delayed. Therefore, the upper small intestine dose not receive a large, rapidly introduced hyperosmolar bolus to initiate the release of humoral substances causing the syndrome. All revisions utilized are potentially ulcerogenic and if vagotomy has not been a part of the original procedure, it should routinely be performed at the time of revision. Patients who have primarily has a Billroth II gastrectomy will frequently improve markedly with simple conversion to a Billroth I reconstruction. This is particularly true when the residual stomach is moderately large (i.e., after antrectomy) and when the gastrojejunal stoma is larger in diameter than the normal jejunum. Under such circumstances approximately 80 per cent of patients will improve sufficiently so that a more complex procedure need not be utilized at once. Under all other conditions we prefer a 10 cm. segment of reversed jejunum anastomosed proximally to the gastric stump and distally to a 40 cm. isoperistaltic Roux-en-Y jejunal limb. This procedure is so successful that one can justify its use as first recourse even in the anatomically favorable Billroth II patient. It should be pointed out emphatically that an isoperistaltic jejunal interposition (Henley loop) has little or no effect on the early postprandial dumping syndrome and should not be considered. Plicated loops of intestine to recreate a gastric reservoir frequently fail to empty satisfactorily and the incidence of satisfactory results is too low to consider their utilization in surgical treatment of the dumping syndrome.

[Dumping syndrome following selective proximal vagotomy].

The dumping syndrome after selective proximal vagotomy associated with plastic operations on the pylorobulbar zone developed in 69.2% of patients, Jabuley's gastroduodenostomy being most frequently followed by it. In patients with duodenal ulcer complicated by stenosis of the gastric pylorus and who are predisposed to dumping syndrome the operation of choice should be selective proximal vagotomy associated with exclusion of the duodenum and formation of "end-to-end" gastroenteroanastomosis and Y-shaped entero-enteroanastomosis after Roux. The dumping syndrome can be prevented by performing the operation (SPV) at early periods of the disease before developing the pylorobulbar stenosis when no additional draining operations are necessary.

[Treatment methods for the dumping syndrome].

An incidence was determined of dumping syndrome after various operations while studying results of surgical treatment of gastric and duodenal ulcer in 135 patients. In dumping syndrome, two variants of association of motility of the stomach stump and efferent intestinal loop were identified. Modes of conservative treatment are proposed, such as transcutaneous electrostimulation of the ileocecal portion of the intestine and prescription of Zbruchansk (naftusia-type) mineral water.

Benefit of uncooked cornstarch in the management of children with dumping syndrome fed exclusively by gastrostomy.

OBJECTIVES: Children with dumping syndrome fed exclusively by gastrostomy are difficult to manage because liquid diets are given directly into the antrum. The gastric contents are emptied rapidly into the small intestine, with consequent hyperglycemia followed by a delayed hypoglycemia and multiple, often debilitating, symptoms. Uncooked cornstarch is a complex carbohydrate that provides a slow and continuous glucose source and may delay gastric emptying. The objective of this study was to determine the efficacy of uncooked cornstarch in the treatment of these children. METHODS: The medical records of eight children with dumping syndrome fed exclusively by gastrostomy were reviewed. Dumping syndrome was diagnosed if there was consistent symptomatology, rapid gastric emptying, and abnormal glucose measurements after a glucose tolerance test. Enough uncooked cornstarch to match hepatic glucose production for 4 h was added to control hypoglycemia, and the feeding formula was modified to control hyperglycemia. RESULTS: All patients had debilitating symptoms. Weight z-score on admission was -2.31 +/- 0.29. Glucose shifts were controlled in all. There was a significant difference between the maximum (221.3 +/- 19.3 mg/dl vs 121.3 +/- 6.9 mg/dl; p < 0.008) and minimum serum glucose (47 +/- 7.8 mg/dl vs 65.6 +/- 4 mg/dl; p < 0.04) before and after uncooked cornstarch. Weight increased from 11.87 +/- 1.4 kg to 15.10 +/- 2.3 kg (p = 0.06). In seven patients, bolus feedings were successfully administered, and symptoms improved or resolved. CONCLUSIONS: Uncooked cornstarch controlled the glucose shifts, resolved most of the symptoms, allowed bolus feedings, and enhanced weight gain in these children.

The effect of somatostatin in dumping syndrome after gastric surgery.

The effect of somatostatin on early and late dumping syndrome was studied in 12 patients with gastric resection. Each patient underwent two glucose challenges with 75 gram of glucose administered orally. In the control study isotonic sodium chloride was given, while in the other study cyclic somatostatin in a dose of 80 ng/kg/min was given for a period of 270 minutes. In the control study all patients showed subjective symptoms of the early dumping syndrome with significant (p < 0.001) increases in pulse rate, hematocrit, and vasoactive intestinal polypeptide. Ten patients showed asymptomatic hypoglycemia, as a sign of the late dumping syndrome associated with a significant (p < 0.001) increase of insulin, gastric inhibitory peptide and glucagon levels. During the administration of somatostatin these changes failed to develop. The difference between the results of the two challenges are significant. These results indicate that somatostatin alleviates the symptoms both of early and late dumping syndrome partly by inhibiting the vasoactive intestinal polypeptide, gastric inhibitory peptide and insulin release, which are increased in dumping syndrome and may, therefore, be implicated as to have an etiological role.

Dumping syndrome: pathophysiology and treatment.

Anatomic and physiologic changes introduced by gastric surgery result in clinically significant dumping syndrome in approximately 10% of patients. Dumping is the effect of alteration in the motor functions of the stomach, including disturbances in the gastric reservoir and transporting function. Gastrointestinal hormones play an important role in dumping by mediating responses to surgical resection. Treatment options of dumping syndrome include diet, medications, and surgical revision. Poor nutrition status can be anticipated in patients who fail conservative therapy. Management of refractory dumping syndrome can be a challenge. This review highlights current knowledge about the mechanisms of dumping syndrome and available therapy.
