Hypoglycemic Convulsive Seizure Due to Late Dumping Syndrome

Dumping syndrome is a common complication of esophageal or gastric surgery. Patients with late dumping syndrome usually suffer from hypoglycemic symptoms such as palpitation, tremor, and general weakness. Hypoglycemia induced convulsive seizure due to late dumping syndrome is rarely reported. We report a 46-year-old man with postprandial hypoglycemic convulsive seizure as the first symptom of late dumping syndrome.

Pregnancy and Dumping Syndrome post-bariatric surgery: a case report

This case report discusses dumping syndrome in the postbariatric mother. Diagnostically a challenge, the symptoms of postprandial hypoglycaemia mimic common early gestation complaints and may go undiagnosed, thus requiring a high index of suspicion. As weight-loss surgery gains traction, it is pertinent to note at booking and followups. The pregnancy is at-risk and multidisciplinary team management is central. The mainstay of management remains diet modification. There have been case reports of successful medical treatment of dumping syndrome in pregnancy with good maternal and fetal outcomes. However, more data is needed regarding the usage of these medical treatments in pregnancy.

Nesidioblastosis del adulto tras derivación gástrica / Nesidioblastosis in the adult following gastric bypass

La hipoglucemia por hiperinsulinismo endógeno ha sido descrita como una complicación de la cirugía bariátrica. Se presenta el caso de un hombre de 34 años con tríada de Whipple que se manifestó ocho años después de someterse a derivación (bypass) gástrica. La hipoglucemia se asociaba con niveles elevados de insulina y péptido C, pero la localización del hiperinsulinismo endógeno solo se pudo precisar mediante cateterismo de arterias pancreáticas con estimulación intraarterial selectiva con calcio. Se decidió practicar una pancreatectomía subtotal laparoscópica, después de la cual el paciente presentó una excelente evolución posoperatoria y mejoró significativamente su sintomatología. Mediante la evaluación histopatológica e inmunohistoquímica, se confirmó una nesidioblastosis del adulto. Es importante reconocer esta enfermedad como una complicación de la cirugía bariátrica, más aún cuando estos procedimientos son tan frecuentes en la actualidad debido a la epidemia de obesidad. Los síntomas se pueden confundir con los de un síndrome de evacuación gástrica rápida (dumping), el cual no tiene repercusiones tan graves sobre la salud del paciente, como sí la tiene la nesidioblastosis

Hypoglycemia due to endogenous hyperinsulinism has been described as a complication of bariatric surgery. We present the case of a 34-year-old man who developed a Whipple's triad eight years after undergoing gastric bypass. Hypoglycemia was associated with high serum levels of insulin and C peptide; anatomic localization of endogenous hyperinsulinism was finally demonstrated with a selective intra-arterial calcium-stimulation test. Patient was offered a laparoscopic subtotal pancreatectomy, which resulted in an excellent postoperative course and significant symptoms resolution. Pathology report and inmunohistochemical analysis confirmed the diagnosis of adult nesidioblastosis. We believe it is important to recognize this condition as a complication of bariatric surgery, a procedure performed more frequently nowadays due to the obesity epidemic. Symptoms might be confused with those of dumping syndrome which does not have severe consequences in the patient´s health as nesidioblastosis does

PATHOPHYSIOLOGY, DIAGNOSIS AND TREATMENTOF DUMPING SYNDROME AND ITS RELATION TO BARIATRIC SURGERY / FISIOPATOLOGIA, DIAGNÓSTICO E TRATAMENTO DA SÍNDROME DE DUMPING E SUA RELAÇÃO COM A CIRURGIA BARIÁTRICA

ABSTRACT Introduction The dumping syndrome is frequent in bariatric surgery. It is probably the most common syndrome following partial or complete gastrectomy. Its prevalence in partial gastrectomy can reach up to 50%, thus it can be a significant complication arising from some types of bariatric surgeries. Objective: Critical analysis on dumping syndrome, its pathophysiology, diagnosis and treatment. Methods: A literature review was performed using the key words: 'dumping syndrome', 'bariatric surgery' and 'rapid dumping syndrome'. Inclusion criteria were: books, original works, case reports and meta-analyzes, and the exclusion criterion was literature review. Concerning the publication time, articles were screened between 1960 and May 2015. Results: The dumping syndrome is complication arising from obesity surgeries, but also can be a result of vagus nerve damage. Diagnosis is done primarily through the use of questionnaires based on scores. Conclusion: The Sigstad score and Arts survey are valid means for assessing the dumping syndrome. Initial therapy consists in the adoption of dietary measures, short acting drugs administration.

RESUMO Introdução: A síndrome de dumping é frequente após operações bariátricas. É, provavelmente, a mais comum das síndromes que sucedem gastrectomias parciais ou completas. Sua prevalência, em gastrectomias parciais pode chegar a até 50%, tornando-se assim complicação significante em alguns tipos de operações bariátricas. Objetivo: Realizar análise crítica sobre a síndrome de dumping em sua fisiopatologia, diagnóstico e tratamento. Métodos: Foi realizada revisão bibliográfica utilizando os descritores: 'síndrome de dumping', 'cirurgia bariátrica' e 'síndrome do esvaziamento rápido'. Os critérios de inclusão foram: livros, trabalhos originais, relatos de caso e metanálises; excluíram-se as revisões bibliográficas. Quanto ao tempo de publicação, foram selecionados artigos entre 1960 e maio de 2015. Resultados: A síndrome de dumping é complicação gastrointestinal oriunda de operações para obesidade, mas também pode ocasionar-se como consequência de danos no nervo vago. Seu diagnóstico é realizado primordialmente através da aplicação de questionários baseados em pontuações. Conclusão: O escore de Sigstad e questionário de Arts são meios válidos para avaliação da síndrome de dumping. A terapia inicial consiste na adoção de medidas dietéticas, ou fármacos administráveis de ação curta.

ASSESSMENT OF THE GASTRO-JEJUNO-DUODENAL TRANSIT AFTER JEJUNAL POUCH INTERPOSITION / AVALIAÇÃO DO TRÂNSITO GASTROJEJUNODUODENAL APÓS INTERPOSIÇÃO DE ALÇA JEJUNAL

Background : The jejunal pouch interposition between the gastric body and the duodenum after the gastrectomy, although not frequent in the surgical practice today, has been successfully employed for the prevention and treatment of the postgastrectomy syndromes. In the latter, it is included the dumping syndrome, which affects 13-58% of the patients who undergo gastrectomy. Aim : Retrospective assessment of the results of this procedure for the prevention of the dumping syndrome. Methods : Fourty patients were selected and treatetd surgically for peptic ulcer, between 1965 and 1970. Of these, 29 underwent vagotomy, antrectomy, gastrojejunalduodenostomy at the lesser curvature level, and the 11 remaining were submitted to vagotomy, antrectomy, gastrojejunal-duodenostomy at the greater curvature level. The gastro-jejuno-duodenal transit was assessed in the immediate or late postoperative with the contrasted study of the esophagus, stomach and duodenum. The clinical evolution was assessed according to the Visick grade. Results : Of the 40 patients, 28 were followed with the contrast evaluation in the late postoperative. Among those who were followed until the first month (n=22), 20 (90%) had slow gastro-jejuno-duodenal transit and in two (10%) the transit was normal. Among those who were followed after the first month (n=16), three (19%) and 13 (81%) had slow and normal gastric emptying, respectively. None had the contrasted exam compatible with the dumping syndrome. Among the 40 patients, 22 underwent postoperative clinical evaluation. Of these, 19 (86,5%) had excellent and good results (Visick 1 and 2, respectively). Conclusions : The jejunal pouch interposition showed to be a very effective surgical procedure for the prevention of the dumping syndrome in gastrectomized patients.

Racional : A interposição de alça jejunal entre o corpo gástrico e o duodeno após a antrectomia, apesar de pouco frequente na prática cirúrgica atual, tem sido empregada com sucesso na prevenção e tratamento das síndromes pós-gastrectomias. Entre estas se inclui a síndrome de dumping, que acomete 13-58% dos pacientes gastrectomizados. Objetivo : Avaliação retrospectiva dos resultados desse procedimento na prevenção da síndrome de dumping. Métodos : Foram selecionados 40 pacientes todos encaminhados para tratamento cirúrgico de úlcera cloridropéptica entre 1965 e 1970. Destes, 29 foram submetidos à vagotomia, antrectomia, gastrojejunoduodenostomia no nível da pequena curvatura, e os 11 restantes à vagotomia, antrectomia, gastrojejunoduodenostomia no nível da grande curvatura. O trânsito gastrojejunoduodenal foi avaliado no pós-operatório imediato ou tardio por meio do estudo contrastado de esôfago, estômago e duodeno. A evolução clínica no pós-operatório foi avaliada segundo a classificação de Visick. Resultados : Dos 40 pacientes, 28 foram acompanhados com o estudo contrastado no pós-operatório tardio. Entre aqueles de até o 1º mês de pós-operatório (n=22), 20 (90%) apresentaram o trânsito gastrojejunoduodenal lento e dois (10%) tiveram o trânsito normal. Entre os que puderam ser acompanhados após o 1º mês (n=16), três (19%) e 13 (81%) mostraram o esvaziamento gástrico lento e normal, respectivamente. Nenhum apresentou o estudo contrastado compatível com a síndrome de dumping. Entre os 40 doentes, 22 foram submetidos à avaliação clínica pós-operatória. Destes, 19 (86,5%) apresentaram excelentes e bons resultados (Visick 1 e 2, respectivamente). Conclusões : A interposição de alça jejunal mostrou-se procedimento cirúrgico bastante eficaz na prevenção da síndrome de dumping em pacientes gastrectomizados.

A Case of Type 2 Diabetes Mellitus with Severe Insulin Resistance and Dumping Syndrome after Bariatric Surgery

Patients with diabetes undergo bariatric surgery to improve sugar metabolism and to achieve weight loss. However, possible complications after bariatric surgery must be carefully considered. We report a case of uncontrolled blood sugar after bariatric surgery despite weight loss in a severely obese patient with diabetes. The patient underwent bariatric surgery in 2009 in order to lose weight and improve glycemic control. Six months after the surgery, the patient experienced dumping syndrome. The patient did actually lose weight; however, as the visceral fat/subcutaneous fat+visceral fat ratio increased, insulin resistance was not improved, and glycemic control was aggravated. The patient received proper medication for dumping syndrome including nutritional support and exercise education. Due to these efforts, the patient has maintained her weight loss, and her blood sugar level was controlled within the target range.

A Prospective Observational Study Evaluating the Change of Nutritional Status and the Incidence of Dumping Syndrome after Gastrectomy

PURPOSE: The aim of this study was to investigate the change of nutritional status and the incidence of dumping syndrome after gastrectomy for gastric cancer. METHODS: From January 2013 to May 2014, 36 patients who underwent gastrectomy for gastric cancer were prospectively investigated in terms of nutritional status by body weight, anthropometric measurements, biochemical data, and Patient-Generated Subjective Global Assessment (PG-SGA). Dumping syndrome was assessed using a newly developed questionnaire based on the Japanese Society of Gastroenterological Surgery survey and Sigstad's scoring system. RESULTS: Body weight losses were 4.6%, 8.1%, and 6.9% at discharge, six months, and one year after discharge, respectively. Triceps skinfold thickness had no significance, however, mid-arm muscle circumference showed significant loss after gastrectomy. A part of the biochemical data showed significant change after gastrectomy, but almost indicated a restoring tendency within two months after discharge. In terms of PG-SGA, 33 patients (91.7%) were classified as A (well-nourished) before surgery, however, the number of well-nourished patients showed a sharp decrease to 1 (2.8%) at two weeks after discharge, and then gradually increased to 25 (69.4%) at one year. The main obstacles against diet intake were reported as 'early satiety' and 'anxiety'. The number of patients who had experience in at least one dumping syndrome related symptom was 21 (58.3%) at discharge, 26 (72.2%) at two months after discharge, and 11 (30.6%) at one year after discharge. CONCLUSION: Nutritional deficit as well as dumping syndrome is encountered in a large number of gastric cancer patients after gastrectomy. Postoperative nutritional support and personalized education seem to be very important during the postoperative period.

Treatment with acarbose in severe hypoglycaemia due to late dumping syndrome / Tratamiento con acarbosa en la hipoglicemia severa debido al síndrome de dumping tardío

BACKGROUND: We present a case of recurrent loss of consciousness, which was finally accurately diagnosed as late dumping syndrome twelve years after subtotal gastrectomy and successfully treated with acarbose. A 66-year old lean male was found unconscious repeatedly within one year. Oral glucose tolerance tests performed before and after acarbose treatment verified the diagnosis of late dumping syndrome. Acarbose can be used as a successful treatment modality for reactive hypoglycaemia due to late dumping syndrome by influencing the release of hormone.

ANTECEDENTES: Presentamos un caso de pérdida recurrente de conciencia, que fue finalmente diagnosticado con precisión como síndrome de dumping tardío, doce años después de la gastrectomía subtotal, y tratado con éxito con acarbosa. Un hombre magro de 66 años de edad fue encontrado inconsciente repetidas veces en un año. Las pruebas orales de tolerancia a la glucosa realizadas antes y después del tratamiento con acarbosa verificaron el diagnóstico de síndrome de dumping tardío. La acarbosa puede utilizarse como una modalidad de tratamiento acertado para la hipoglicemia reactiva debido al síndrome de dumping tardío por la influencia en la liberación de hormonas.

Nutritional Status and Dietary Change after Gastrectomy of Gastric Cancer Patients / 대한지역사회영양학회지

The purpose of this survey is to investigate the nutritional status and dietary intake of gastrectomized cancer patients in Asan Medical Center. The subjects were 98 patients, who underwent a gastrectomy due to gastric cancer and were admitted to the General Surgery Department during March 2007 to December 2007. We examined general characteristics (sex, age, clinicopathological stage, type of operation), anthropometric data (height, weight change), biochemical data (red blood cell RBC, hemoglobin HGB, hematocrit HCT, mean corpuscular volume MCV, total lymphocyte count TLC, albumin, total cholesterol), dietary intake and dietary intake related symptoms. Weight loss of gastrectomized patients was 9.0 +/- 4.3% from preillness weight to visiting out-patient department (OPD) weight. Biochemical data (RBC, HGB, HCT, MCV, TLC, albumin, total cholesterol) significantly deteriorated after gastrectomy. However, outpatient visits were all restored to the normal range. Postoperative energy intake was 785.0 +/- 164.2 kcal, which corresponds to 41.6 +/- 9.6% of daily energy requirement. The cause of poor oral intake is mostly fear, abdominal pain and abdominal discomfort. Therefore, to control pre-or post-operative weight change in the future requires, focusing on the body weight to maintain a normal or usual nutrition by interventions and increased caloric intake during hospitalization for the development of nutrient-dense meals. In addition, as the main reason of the lack of intake of meals after the gastrectomy was fear, the patients should be actively encouraged to consider the importance of eating proper meals.

Avaliação da síndrome de dumping em pacientes obesos mórbidos submetidos à operação de bypass gástrico com reconstrução em Y de Roux / Analysis of the dumping syndrome on morbid obese patients submitted to Roux en Y gastric bypass

OBJETIVO: Determinar a prevalência da síndrome de dumping em uma série de casos submetidos ao bypass gástrico, baseado em critérios clínicos, e caracterizar seus principais aspectos. MÉTODOS: Foi realizada uma análise dos sintomas descritos como dumping em 34 pacientes obesos mórbidos submetidos ao bypass gástrico com reconstrução em Y de Roux, por meio do preenchimento de um questionário que incluiu um sistema de escore para o diagnóstico clínico da síndrome de dumping, descrito por Sigstad. RESULTADOS: A ocorrência de dumping com base em critérios subjetivos foi de 44 por cento. Aplicando o escore para diagnóstico clínico, a ocorrência foi de 76 por cento. Os sintomas mais freqüentes foram "vontade de deitar" (88 por cento), cansaço (69 por cento) e sono (69 por cento). Apenas 28 por cento dos pacientes com dumping se sentiram incapacitados para a realização das atividades cotidianas. Não foi observada diferença entre o percentual de perda de peso dos pacientes dumpers e não-dumpers. CONCLUSÃO: O escore de Sigstad se mostrou uma ferramenta útil para o diagnóstico de dumping, embora uma visão crítica deva ser adotada quando utilizado em pacientes submetidos ao bypass gástrico. A síndrome de dumping foi frequente nesta população, embora geralmente subestimada, não sendo incapacitante para a realização das atividades cotidianas dos pacientes, assim como não se mostrou um fator relevante no auxílio à perda de peso.

OBJECTIVE: The objective of this research was to determine the real prevalence and characteristics of dumping syndrome in a series of cases submitted to laparoscopic Roux-en-Y gastric bypass for morbid obesity. METHODS: We assessed dumping symptoms in 34 patients who had undergone that procedure; they filled a questionnaire, which included the dumping clinical diagnosis score proposed by Sigstad. RESULTS: regarding patients' complaints, dumping prevalence was 44 percent. This number increased to 76 percent when applying the Sigstad's score. The most frequent symptoms were "need for lying down" (88 percent), fatigue (69 percent) and sleepiness (69 percent). Only 28 percent of the dumpers felt incapable of performing everyday activities. There was no difference in weight loss percentage between dumpers and non-dumpers. CONCLUSION: The Sigstad score is an usefull tool for the diagnostic of dumping, but a critic vision must be adopted when using in pacients submited to the Roux en Y gastric bypass. The dumping syndrome was frequent in this group, although usually under-diagnosed; it neither hampers patients' everyday activities considerably, nor helps in the weight-loosing process.

Four Cases Report of Dumping Syndrome Effectively Treated with Keishito and its additional Prescription / 日本東洋医学雑誌

We report four patients suffering from dumping syndrome treated effectively with Keishito and its additional prescription. Case1was a 57-year old male who received subtotal gastrectomy 30 years ago. After the operation he felt shaking sensations and eyes flickering after meals for10minutes to 4 hours. These symptoms tended to occur along with hunger. After taking Keishito, these symptoms improved. Case 2 was a 63-year old male who received subtotal gastrectomy 7 years ago. In recent years, he has had noticeable sweat and fatigability 20-30 minutes after meals. After taking Keishito, these dumping syndrome symptoms disappear. Case 3 was a 71-year old female who received subtotal gastrectomy 9 years ago. Thereafter, cold sweats and dizziness came to appear regardless of what she ate. After taking keishikashakuyakuto or shokenchuto the aforementioned symptoms disappeared. Case 4 was a 72-year old female who received subtotal gastrectomy 2 years ago. Sweats and hot flushes began to occur after meals for 30 minutes to 3 hours, from last July. These symptoms were improved simply by licking candy. After taking Keishito, these symptoms also disappeared.

Dumping Syndrome in a Child with Gastrojejunal Tube Feeding / 대한소아소화기영양학회지

Dumping syndrome is a known complication of gastric surgery in adults, but a very rare disease in the pediatric population. We report on a case of dumping syndrome in a 19-month-old child, who underwent gastrojejunal feeding tube insertion for the treatment and prevention of gastroesophageal reflux and frequent aspiration pneumonia. At 17 months of age, 2 months after the beginning of gastrojejunal tube feeding, postprandial diaphoresis, palpitation, lethargy, bloating, and diarrhea occurred, and a single episode of convulsion with hypoglycemia were noted. Early and late dumping syndrome was confirmed by an abnormal oral glucose tolerance test with early onset hyperglycemia followed by delayed onset hypoglycemia. Diet therapy including uncooked corn starch then improved the postprandial diaphoresis, abnormal glucose levels, and her nutritional status. We conclude that dumping syndrome may be considered as a complication of gastrojejunal tube feeding in a child.

Duodenojejunostomia látero-lateral: uma alternativa cirúrgica para o tratamento do "dumping" pós gastrectomia / Side to side duodenojejunostomy: a surgical alternative for dumping after gastrectomy

Most patients with partiaI gastrectomy have no postoperative problems. Some of them, however, develop severe nutritional disturbance, particularly those with Bilroth II reconstruction, which can be treated clinically in the majority of the cases. Those with important mal absorptive problems require surgery. In this article we present a technical alternative for those patients who need reintervention over a BII operation. Our technique has the advantage of not touching the duodenum previously sutured.

A case of dumping syndrome presenting as hypoglycemic shock with dramatic improvement by octreotide treatment / 대한내과학회지

Following gastric surgery, 25~50% of patients experience dumping symptoms. Early dumping usually involves both gastro-intestinal and vasomotor complaints, while late dumping involves mainly the latter. Management is mainly achieved by dietary modification. Drug therapy has been investigated without consistent success. However, the somatostatin analogue octreotide alleviates dumping by slowing gastric emptying, inhibiting insulin release, decreasing enteric peptide secretion and intestinal absorption of water and sodium, slowing monosaccharide absorption, increasing gut transit time and preventing hemodynamic changes. We report a case with the place of octreotide in the medical management of the dumping syndrome. The patient was 71-year-old male who had taken total gastrectomy for gastric cancer in 1987. He had been well except intermittent abdominal pain for 8 years after total gastrectomy. But he had suffered from sudden symptoms such as hypoglycemic shock and fainting, which start 2~3 hours after ingesting of a meal for recent 5 years. Studies for diagnosing insulinoma were all negative. We start diet modification and medication such as acarbose to him with impression of dumping syndrome, but there were no improvement of his symptoms. Then we start octreotide, 50 g, given subcutaneously, three-times per day, 30 min prior to each meal. His symptom was dramatically improved.

A Case of Dumping Syndrome Following Nissen Fundoplication in an Infant / 대한소아소화기영양학회지

The dumping syndrome has been a known complication of gastric surgery in adults, but it is recognized as a very rare disease in the pediatric population, especially in Korea. We report a case of dumping syndrome in a 10-month-old infant, who underwent Nissen fundoplication for the treatment of gastroesophageal reflux(GER). He was admitted because of aspiration pneumonia, and diagnosed as GER by 24-hour ambulatory esophageal pH monitoring test. For the treatment of GER, Nissen fundoplication was performed. After the operation, symptoms occurred within 30 minutes of meals, such as diaphoresis, palpitation, weakness, abdominal fullness, nausea, and diarrhea. The gastric emptying scan showed very rapid gastric emptying. His oral glucose tolerance tests revealed early-onset hyperglycema followed by delayed-onset hypoglycemia, which was the characteristic finding of the dumping syndrome. We introduced uncooked cornstarch to resolve symptoms and maintain the serum glucose level. After the feeding of uncooked cornstarch, his symptoms subsided and normal oral glucose test was restored. After the six months of treatment, his weight and height were increased dramatically from below 3 percentiles up to the normal range. The dumping syndrome should be considered when an infant suffers from the feeding difficulties after the gastric surgery like Nissen fundoplication, and the diet therapy including uncooked cornstarch could be applied as an effective measure.

Effects of subtotal gastrectomy on vasoactive intestinal peptide release / 第三军医大学学报

In order to evaluate the effects of subtotal gastrectomy on the release of vasoactive intestinal peptide (VIP) into the blood,blood samples were taken from 10 patients after Billroth Ⅰ operation (B-Ⅰ),15 patients after Billroth Ⅱ operation (B-Ⅱ),15 patients after antroseromuscular flap preserving gastrectomy (PAFPG),and 8 normal subjects who served as the control.The blood samples were taken after the individual took hypertonic glucose solution.It was found that the VIP elevation rate was significantly higher in B-Ⅰ and B-Ⅱ group than in PAFPG group (P 0.05).In B-Ⅰ and B-Ⅱ,the VIP elevation rate was significantly higher in those cases with dumping syndrome than in those without (P
