Neurotensin secretion after Roux-en-Y gastric bypass, sleeve gastrectomy, and truncal vagotomy with pyloroplasty. Neurogastroenterol Motil 2022; 34:e14210. [PMID: 34378827 DOI: 10.1111/nmo.14210] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Revised: 04/30/2021] [Accepted: 05/31/2021] [Indexed: 02/08/2023]
Abstract
OBJECTIVE Neurotensin (NT) is released from enteroendocrine cells and lowers food intake in rodents. We evaluated postprandial NT secretion in humans after surgeries associated with accelerated small intestinal nutrient delivery, and after Roux-en-Y gastric bypass (RYGB) when glucagon-like peptide-1 (GLP-1) signalling and dipeptidyl peptidase 4 (DPP-4) were inhibited, and during pharmacological treatments influencing entero-pancreatic functions. METHODS We measured NT concentrations in plasma from meal studies: (I) after truncal vagotomy with pyloroplasty (TVP), cardia resection +TVP (CTVP), and matched controls (n = 10); (II) after RYGB, sleeve gastrectomy (SG), and in matched controls (n = 12); (III) after RYGB (n = 11) with antagonism of GLP-1 signalling using exendin(9-39) and DPP-4 inhibition using sitagliptin; (IV) after RYGB (n = 11) during a run-in period and subsequent treatment with, sitagliptin, liraglutide (GLP-1 receptor agonist), verapamil (calcium antagonist), acarbose (alpha glucosidase inhibitor), and pasireotide (somatostatin analogue), respectively. RESULTS (I) NT secretion was similar after TVP/CTVP (p = 0.9), but increased vs. controls (p < 0.0001). (II) NT secretion was increased after RYGB vs. SG and controls (p < 0.0001). NT responses were similar in SG and controls (p = 0.3), but early postprandial NT concentrations were higher after SG (p < 0.05). (III) Exendin (9-39) and sitagliptin did not change NT responses vs placebo (p > 0.2), but responses were lower during sitagliptin vs. exendin(9-39) (p = 0.03). (IV) Pasireotide suppressed NT secretion (p = 0.004). Sitagliptin tended to lower NT secretion (p = 0.08). Liraglutide, verapamil, and acarbose had no effect (p > 0.9). CONCLUSION Neurotensin secretion is increased after surgeries associated with accelerated gastric emptying and lowered by pasireotide.

Late-onset rapid gastric emptying: Identification of a new abnormal finding in patients with otherwise normal results on gastric emptying scintigraphy. Neurogastroenterol Motil 2021; 33:e14219. [PMID: 34562335 DOI: 10.1111/nmo.14219] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Revised: 06/24/2021] [Accepted: 06/25/2021] [Indexed: 02/08/2023]
Abstract
BACKGROUND The 4-h gastric emptying (GE) scintigraphy protocol is the gold standard for assessing GE. Rapid gastric emptying (RGE) is >30% emptied by 30 min and >65% emptied at1 h. We observed that some GE studies demonstrated rapid emptying at a later time although interpreted as normal (NGE) at 4 h. We aimed to establish thresholds to characterize this subset of late-onset rapid gastric emptying (LRGE). METHODS We retrospectively analyzed 4-h GE studies of 425 patients with upper GI symptoms who fulfilled the criteria for NGE. We recruited 24 normal subjects to establish GE cutoff values (mean +/- 2SD) at 1-2, 2-3, and 3-4 h. These thresholds were applied to the 425 patients with NGE. During every GE study, patients graded their postprandial symptoms on a scale from 0 to 4. KEY RESULTS The mean upper threshold decrement limits were calculated from the normal volunteers as 67.6% at 1-2 h, 48.7% at 2-3 h, and 27.9% at 3-4 h. After applying these values to the NGE patients, 19 (4.5%) were classified as having LRGE; 6 patients (1.4%) for the 2- to 3-h; and 13 (3.1%) for the 3- to 4-h period. Patients with LRGE had abdominal pain, bloating, nausea, or diarrhea beginning more than 1-h postprandial. CONCLUSION 5% of patients classified as "normal" at 4 h had an abnormal GE pattern based on the proposed criteria for LRGE. This highlights the importance of applying these hourly decrement thresholds to identify LRGE as a new diagnostic entity explaining postprandial symptoms.

Abstract
Dumping syndrome is a common but underdiagnosed complication of gastric and oesophageal surgery. We initiated a Delphi consensus process with international multidisciplinary experts. We defined the scope, proposed statements and searched electronic databases to survey the literature. Eighteen experts participated in the literature summary and voting process evaluating 62 statements. We evaluated the quality of evidence using grading of recommendations assessment, development and evaluation (GRADE) criteria. Consensus (defined as >80% agreement) was reached for 33 of 62 statements, including the definition and symptom profile of dumping syndrome and its effect on quality of life. The panel agreed on the pathophysiological relevance of rapid passage of nutrients to the small bowel, on the role of decreased gastric volume capacity and release of glucagon-like peptide 1. Symptom recognition is crucial, and the modified oral glucose tolerance test, but not gastric emptying testing, is useful for diagnosis. An increase in haematocrit >3% or in pulse rate >10 bpm 30 min after the start of the glucose intake are diagnostic of early dumping syndrome, and a nadir hypoglycaemia level <50 mg/dl is diagnostic of late dumping syndrome. Dietary adjustment is the agreed first treatment step; acarbose is effective for late dumping syndrome symptoms and somatostatin analogues are preferred for patients who do not respond to diet adjustments and acarbose.

Abstract
Gastroparesis and dumping syndrome both evolve from a disturbed gastric emptying mechanism. Although gastroparesis results from delayed gastric emptying and dumping syndrome from accelerated emptying of the stomach, the two entities share several similarities among which are an underestimated prevalence, considerable impairment of quality of life, the need for a multidisciplinary team setting, and a step-up treatment approach. In the following review, we will present an overview of the most important clinical aspects of gastroparesis and dumping syndrome including epidemiology, pathophysiology, presentation, and diagnostics. Finally, we highlight promising therapeutic options that might be available in the future.

Abstract
BACKGROUND Early dumping is a poorly defined and incompletely understood complication after Roux-en-Y gastric (RYGB). OBJECTIVE We performed a mixed-meal tolerance test in patients after RYGB to address the prevalence of early dumping and to gain further insight into its pathophysiology. SETTING The study was conducted in a regional hospital in the northern part of the Netherlands. METHODS From a random sample of patients who underwent primary RYGB between 2008 and 2011, 46 patients completed the mixed-meal tolerance test. The dumping severity score for early dumping was assessed every 30 minutes. A sum score at 30 or 60 minutes of ≥5 and an incremental score of ≥3 points were defined as indicating a high suspicion of early dumping. Blood samples were collected at baseline, every 10 minutes during the first half hour, and at 60 minutes after the start. RESULTS The prevalence of a high suspicion of early dumping was 26%. No differences were seen for absolute hematocrit value, inactive glucagon-like peptide-1, and vasoactive intestinal peptide between patients with or without early dumping. Patients at high suspicion of early dumping had higher levels of active glucagon-like peptide-1 and peptide YY. CONCLUSION The prevalence of complaints at high suspicion of early dumping in a random population of patients after RYGB is 26% in response to a mixed-meal tolerance test. Postprandial increases in both glucagon-like peptide-1 and peptide YY are associated with symptoms of early dumping, suggesting gut L-cell overactivity in this syndrome.

Abstract
Background In patients with late dumping syndrome following gastrectomy, it has been reported that hypoglycemia occurs due to inhibition of glucagon secretion as a result of excessive insulin production facilitated by an increase in glucagon-like peptide-1 (GLP-1). Methods To determine the kinetics of incretins in Japanese patients with late dumping syndrome, an oral glucose tolerance test was carried out before and after miglitol administration, and the kinetics of insulin and incretins were analyzed. Results After miglitol administration, there was improvement of hypoglycemia and early phase insulin secretion, with persistent excessive insulin secretion being minimized. These findings revealed that miglitol inhibited rapid excessive influx of carbohydrates into the blood and persistent elevation of GLP-1, resulting in improvement of early phase insulin secretion and minimizing persistent excessive insulin secretion. Conclusions Eating frequent small meals is generally effective for late dumping syndrome, but patients often find it difficult to continue such a regimen. Based on the present analysis of incretin kinetics, miglitol may be a useful treatment option for late dumping syndrome.

Abstract
BACKGROUND Dumping syndrome, a common complication of esophageal, gastric or bariatric surgery, includes early and late dumping symptoms. Early dumping occurs within 1 h after eating, when rapid emptying of food into the small intestine triggers rapid fluid shifts into the intestinal lumen and release of gastrointestinal hormones, resulting in gastrointestinal and vasomotor symptoms. Late dumping occurs 1-3 h after carbohydrate ingestion, caused by an incretin-driven hyperinsulinemic response resulting in hypoglycemia. Clinical recommendations are needed for the diagnosis and management of dumping syndrome. METHODS A systematic literature review was performed through February 2016. Evidence-based medicine was used to develop diagnostic and management strategies for dumping syndrome. RESULTS Dumping syndrome should be suspected based on concurrent presentation of multiple suggestive symptoms after upper abdominal surgery. Suspected dumping syndrome can be confirmed using symptom-based questionnaires, glycemia measurements and oral glucose tolerance tests. First-line management of dumping syndrome involves dietary modification, as well as acarbose treatment for persistent hypoglycemia. If these approaches are unsuccessful, somatostatin analogues should be considered in patients with dumping syndrome and impaired quality of life. Surgical re-intervention or continuous enteral feeding may be necessary for treatment-refractory dumping syndrome, but outcomes are variable. CONCLUSIONS Implementation of these diagnostic and treatment recommendations may improve dumping syndrome management.

Abstract
OBJECTIVE Acarbose is a glucosidase inhibitor that slows carbohydrate digestion. It could thus be effective to promote remission of dumping syndrome (DS). Previous studies associating acarbose and late dumping, although not early dumping, have been reported. Herein, we aimed to evaluate the role of acarbose in dumping syndrome prevention and treatment and in resistive exercises resistance in bariatric subjects. METHODS Bariatric patients with DS and complete adherence to diet plan and resistive exercises were included (n=25). Number of early and late episodes, self-referred intensity of each episode, and ability to increase intensity of resistive exercise were evaluated, on a 0-10 scale. Acarbose was administered orally (50 mg) for 6 months, 4-5 times a day before meals. RESULTS Acarbose administration was associated with a decrease in the number of early (2.18-0.31) and late (2.79-0.12) episodes per week and intensity of each episode (6.10-1.65) and an increase in the ability to perform resistive exercises (3.03-7.12). Complete remission of DS was seen in 21 patients (84%), which persisted for 6 months with the use of acarbose. CONCLUSION Acarbose prevented dumping in almost all studied subjects and helped improve exercise capacity.

Abstract
Gastric surgery has long been known to be a cause of dumping syndrome (DS). However, the increasing incidence of gastric bypass surgery, as well as reports of DS unrelated to previous gastric surgeries, has increased the importance of understanding DS in recent years. DS is due to the gastrointestinal response to voluminous and hyperosmolar chyme that is rapidly expelled from the stomach into the small intestine. This response involves neural and hormonal mechanisms. This review encompasses the symptoms, diagnosis, and treatment approaches of DS and also focuses on the current research status of the pathophysiology of DS.

Abstract
In spite of its evident success, several late complications can occur after gastric bypass surgery. One of these is post-gastric bypass hypoglycaemia. No evidence-based guidelines exist in the literature on how to confirm the presence of this syndrome. This study aims to describe and compare the tests aimed at making a diagnosis of post-gastric bypass hypoglycaemia and to provide a diagnostic approach based upon the available evidence. A search was conducted in PubMed, Cochrane and Embase. A few questionnaires have been developed to measure the severity of symptoms in post-gastric bypass hypoglycaemia but none has been validated. The gold standard for provocation of a hypoglycaemic event is the oral glucose tolerance test or the liquid mixed meal tolerance test. Both show a high prevalence of hypoglycaemia in post-gastric bypass patients with and without hypoglycaemic complaints as well as in healthy volunteers. No uniformly established cut-off values for glucose concentrations are defined in the literature for the diagnosis of post-gastric bypass hypoglycaemia. For establishing an accurate diagnosis of post-gastric bypass hypoglycaemia, a validated questionnaire, in connection with the diagnostic performance of provocation tests, is the most important thing missing. Given these shortcomings, we provide recommendations based upon the current literature.

Abstract
BACKGROUND The purpose of this study is to determine the effects of posture and drink volume on gastric/pouch emptying (G/PE), intestinal transit, hormones, absorption, glycaemia, blood pressure and gastrointestinal (GI) symptoms after gastric bypass (Roux-en-Y gastric bypass (RYGB)). METHODS Ten RYGB subjects were studied on four occasions in randomized order (sitting vs. supine posture; 50 vs. 150 ml of labelled water mixed with 3 g 3-O-methyl-D-glucose (3-OMG) and 50 g glucose). G/PE, caecal arrival time (CAT), blood glucose, plasma insulin, glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), peptide YY (PYY), 3-OMG, blood pressure, heart rate and GI symptoms were assessed over 240 min. Controls were ten volunteers with no medical condition or previous abdominal surgery, who were studied with the 150-ml drink in the sitting position. RESULTS Compared to controls, PE (P < 0.001) and CAT (P < 0.001) were substantially more rapid in RYGB subjects. In RYGB, PE was more rapid in the sitting position (2.5 ± 0.7 vs. 16.6 ± 5.3 min, P = 0.02) and tends to be faster after 150 ml than the 50-ml drinks (9.5 ± 2.9 vs. 14.0 ± 3.5 min, P = 0.16). The sitting position and larger volume drinks were associated with greater releases of insulin, GLP-1 and PYY, as well as more hypotension (P < 0.01), tachycardia (P < 0.01) and postprandial symptoms (P < 0.001). CONCLUSIONS Pouch emptying, blood pressure and GI symptoms after RYGB are dependent on both posture and meal volume.

Abstract
OBJECTIVES Functional dyspepsia is predominantly attributed to gastric sensorimotor dysfunctions. The contribution of intestinal chemosensitivity to symptoms is not understood. We evaluated symptoms and plasma hormones during enteral nutrient infusion and the association with impaired glucose tolerance and quality-of-life (QOL) scores in patients with functional dyspepsia vs. healthy controls. METHODS Enteral hormonal responses and symptoms were measured during isocaloric and isovolumic dextrose and lipid infusions into the duodenum in 30 patients with functional dyspepsia (n=27) or nausea and vomiting (n=3) and 35 healthy controls. Infusions were administered in randomized order over 120 min each, with a 120-min washout. Cholecystokinin, glucose-dependent insulinotropic peptide, glucagon-like peptide 1 (GLP1), and peptide YY were measured during infusions. RESULTS Moderate or more severe symptoms during lipid (4 controls vs. 14 patients) and dextrose (1 control vs. 12 patients) infusions were more prevalent in patients than controls (P≤0.01), associated with higher dyspepsia symptom score (P=0.01), worse QOL (P=0.01), and greater plasma hormone concentrations (e.g., GLP1 during lipid infusion). Moderate or more severe symptoms during enteral infusion explained 18%, and depression score explained 21%, of interpatient variation in QOL. Eight patients had impaired glucose tolerance, associated with greater plasma GLP1 and peptide YY concentrations during dextrose and lipid infusions, respectively. CONCLUSIONS Increased sensitivity to enteral dextrose and lipid infusions was associated with greater plasma enteral hormone concentrations, more severe daily symptoms, and worse QOL in functional dyspepsia. These observations are consistent with the hypothesis that enteral hormones mediate increased intestinal sensitivity to nutrients in functional dyspepsia.

Abstract
BACKGROUND Dumping syndrome is characterized by distinct pathophysiological features such as postprandial increase in hematocrit (HT) and pulse rate (PR) and delayed hypoglycemia (HG). Treatment is based on dietary measures and somatostatin analogs (SA), but current SAs have incomplete efficacy, possibly through limited affinity for various somatostatin receptor subtypes. We evaluated the effect of pasireotide, a novel SA with high affinity for 4/5 human somatostatin receptors, on pathophysiological events and symptoms in dumping. METHODS Randomized double-blind placebo-controlled cross-over study of nine patients (six women, 47 ± 4 years) with postoperative dumping. Baseline measurements included oral glucose tolerance testing (OGTT), abdominal ultrasound, and dumping symptom severity score (DSSS). Patients were treated for 2 weeks with placebo or pasireotide 300 μg s.c. t.i.d. with a 1-week wash-out in a randomized fashion. On day 13 and 14 of each treatment OGTT, DSSS, and solid and liquid gastric emptying (GE) were obtained. KEY RESULTS Baseline OGTT was pathological in all patients based on PR (n = 5), HT (n = 1) or HG (n = 7). Compared to placebo, pasireotide suppressed the increase in PR (17.1 ± 2.8 vs 8.2 ± 3.5 bpm; p < 0.05) and late HG (nadir glycemia 55.6 ± 4.3 vs 83.3 ± 9.5 mg/dL; p = 0.007), increased peak glycemia (294.1 ± 33.3 vs 221.0 ± 23.1 mg/dL; p = 0.001) and delayed GE of solids (t1/2 83 ± 23 vs 43 ± 9 min; p = 0.05) and liquids (t1/2 70 ± 10 vs 40 ± 4 min, p = 0.05). The differences in DSSS did not reach statistical significance. Two patients dropped out because of adverse gastrointestinal events under pasireotide. CONCLUSIONS & INFERENCES Pasireotide affects pathophysiological features of both early and late dumping syndrome.

Abstract
A 45-year-old woman who had undergone total gastrectomy for gastric cancer presented with a history of postprandial hypoglycemic episodes with loss of consciousness after meals. Laboratory findings revealed marked hyperinsulinemia and hypoglycemia after a meal. We first treated the patient with octreotide; however, she was unable to continue the treatment because of adverse effects of the drug, such as nausea and headache. Diazoxide was used next for preventing hyperinsulinemia; however, this was not effective for suppressing the postprandial insulin secretion. Since hypoglycemia following gastrectomy is thought to be caused by rapid delivery of nutrients into the duodenum, we performed a meal tolerance test while varying the timing of administration of miglitol in relation to the meal. Miglitol was administered 30 min before, just before, or both 30 min and just before a meal. In the case of administration just before a meal, insulin secretion was suppressed, although hypoglycemia was not prevented. Administration of the drug 30 min before a meal prevented postprandial hypoglycemia by slowing the increase of the blood glucose and serum insulin levels following the meal to a greater degree than administration just before a meal. Miglitol administration both 30 min and just before a meal caused an even smoother increase in blood glucose and serum insulin levels following the meal. In this report, we propose a new therapeutic approach for reactive hypoglycemia after gastrectomy, namely, administration of miglitol 30 min before meals.

Abstract
OBJECTIVE Glucagon-like peptide 1 (GLP1) is rapidly inactivated by dipeptidyl peptidase 4 (DPP4), but may interact with vagal neurons at its site of secretion. We investigated the role of vagal innervation for handling of oral and i.v. glucose. DESIGN AND METHODS Truncally vagotomised subjects (n=16) and matched controls (n=10) underwent 50 g-oral glucose tolerance test (OGTT)±vildagliptin, a DPP4 inhibitor (DPP4i) and isoglycaemic i.v. glucose infusion (IIGI), copying the OGTT without DPP4i. RESULTS Isoglycaemia was obtained with 25±2 g glucose in vagotomised subjects and 18±2 g in controls (P<0.03); thus, gastrointestinal-mediated glucose disposal (GIGD) - a measure of glucose handling (100%×(glucoseOGTT-glucoseIIGI/glucoseOGTT)) - was reduced in the vagotomised compared with the control group. Peak intact GLP1 concentrations were higher in the vagotomised group. Gastric emptying was faster in vagotomised subjects after OGTT and was unaffected by DPP4i. The early glucose-dependent insulinotropic polypeptide response was higher in vagotomised subjects. Despite this, the incretin effect was equal in both groups. DPP4i enhanced insulin secretion in controls, but had no effect in the vagotomised subjects. Controls suppressed glucagon concentrations similarly, irrespective of the route of glucose administration, whereas vagotomised subjects showed suppression only during IIGI and exhibited hyperglucagonaemia following OGTT. DPP4i further suppressed glucagon secretion in controls and tended to normalise glucagon responses in vagotomised subjects. CONCLUSIONS GIGD is diminished, but the incretin effect is unaffected in vagotomised subjects despite higher GLP1 levels. This, together with the small effect of DPP4i, is compatible with the notion that part of the physiological effects of GLP1 involves vagal transmission.

Abstract
BACKGROUND Cyclic vomiting syndrome (CVS) is characterized by stereotypical episodes of vomiting separated by symptom-free intervals. However, the difficulty encountered in the management of patients with CVS may be a reflection of a deficiency in our understanding of the disorder. We aimed to evaluate whether clinical or gastric emptying (GE) data discriminate patients labeled as having CVS from functional vomiting (FV) or irritable bowel syndrome (IBS). METHODS The medical records of patients diagnosed with any vomiting (including CVS, FV) over a 13-year period (1993-2006) at our institution were carefully reviewed. Disease controls were age and gender matched subjects with IBS. Gastric emptying was performed by scintigraphy (99mTc-egg meal). The associations of clinical factors and GE data with patient status (CVS vs FV or IBS) were analyzed. KEY RESULTS A total of 82 patients with CVS and 62 FV patients were identified. Younger age [per 10 years, OR = 0.7 (0.5, 0.9)], male gender [OR = 0.4 (0.2, 0.9)], and cannabinoid use [OR = 2.9 (1.2, 7.2)] were significantly associated with CVS compared with FV. However, there were no significant associations between patient status (CVS vs FV) and age, BMI, smoking, alcohol use, gastrointestinal symptoms, or GE. The proportion of cannabinoid users was significantly higher in patients with CVS compared with patients with IBS, whereas proportions for headaches and psychiatric disease were higher in subjects with IBS. CONCLUSIONS & INFERENCES Cyclic vomiting syndrome (vs FV) was not associated with clinical factors, but was associated with younger age, male gender and cannabinoid use. A larger proportion of CVS (vs IBS) patients had used cannabinoids.

Abstract
Although the surgical treatment of both GERD and obesity is very successful, these procedures have a significant impact on the physiology and function of the proximal GI tract. With the increasing prevalence of both GERD and obesity, more and more patients present at the motility outpatient clinic with symptoms related to surgical interventions for these medical problems. In this review, we describe the main complications following antireflux surgery: dysphagia, gas bloat syndrome, recurrent (persistent) GERD symptoms, and dyspeptic symptoms. The most common motility-related complications of obesity surgery are dumping syndrome and esophageal dysmotility.

Abstract
BACKGROUND Small intestinal bacterial overgrowth (SIBO) is expected in postgastrectomy patients; however, its role has not been clarified. This study was to estimate the prevalence of SIBO and investigate the clinical role of SIBO in postgastrectomy patients. METHODS This prospective study involved 76 patients who underwent gastrectomy for early gastric cancer with no evidence of recurrence. An H(2)-CH(4) breath test with oral glucose challenge test was performed to diagnose SIBO and dumping syndrome. Sigstad dumping questionnaires, serum glucose, hematocrit and pulse rate were simultaneously monitored for every 30 min for 3 hours. KEY RESULTS There were significant differences in SIBO between the postgastrectomy patients and controls (77.6%vs 6.7%, P < 0.01). Abdominal fullness or borborygmus during oral glucose load were more common in SIBO-positive than in negative patients (50.8%vs 17.6%, P = 0.03), and were the independent factors for predicting SIBO in postgastrectomy patients (P = 0.02). The prevalences of dumping syndrome and hypoglycemia after oral glucose were 35 (46.1%) and 19 (25.0%), and were not different between both groups. However, the plasma glucose was significantly lower in SIBO-positive than in SIBO-negative patients at 120 and 150 min after oral glucose load (P < 0.05). No significant differences were observed in pulse rate and hematocrit in both groups. CONCLUSIONS & INFERENCES SIBO is common among postgastrectomy patients. It appears to be associated with postprandial intestinal symptoms and might aggravate late hypoglycemia. SIBO could be a new therapeutic target for managing intestinal symptoms in postgastrectomy patients.

Abstract
Dumping syndrome is a frequent complication of esophageal, gastric or bariatric surgery. Rapid gastric emptying, with the delivery to the small intestine of a significant proportion of solid food as large particles that are difficult to digest, is a key event in the pathogenesis of this syndrome. This occurrence causes a shift of fluid from the intravascular component to the intestinal lumen, which results in cardiovascular symptoms, release of several gastrointestinal and pancreatic hormones and late postprandial hypoglycemia. Early dumping symptoms comprise both gastrointestinal and vasomotor symptoms. Late dumping symptoms are the result of reactive hypoglycemia. Besides the assessment of clinical alertness and endoscopic or radiological imaging, a modified oral glucose tolerance test might help to establish a diagnosis. The first step in treating dumping syndrome is the introduction of dietary measures. Acarbose can be added to these measures for patients with hypoglycemia, whereas several studies advocate guar gum or pectin to slow gastric emptying. Somatostatin analogs are the most effective medical therapy for dumping syndrome, and a slow-release preparation is the treatment of choice. In patients with treatment-refractory dumping syndrome, surgical reintervention or continuous enteral feeding can be considered, but the outcomes of such approaches are variable.

Abstract
BACKGROUND & AIMS Several studies have established symptomatic and mechanistic benefits of the somatostatin analogue octreotide in patients with dumping syndrome, but clinical use is hampered by the requirement for subcutaneous administration 3 times daily. We compared the efficacy of subcutaneous octreotide with that of the long-acting repeatable (LAR) octreotide formulation, which is administered monthly, in patients with dumping syndrome. METHODS The study included 30 consecutive patients with postoperative dumping, evidenced by oral glucose tolerance test (OGTT) results and insufficient response to dietary measures. OGTT, dumping severity score (summary of scores 0-3 for 8 early and 6 late dumping symptoms), and quality-of-life data were evaluated at baseline, after 3 days of subcutaneous administration of octreotide (0.5 mg), and then after 3 monthly intramuscular injections of octreotide LAR (20 mg). RESULTS Both formulations of octreotide significantly reduced total dumping severity scores (21.7 +/- 1.6 at baseline, 11.2 +/- 1.2 for subcutaneous and 14.0 +/- 1.8 for LAR formulations; P < .05). This reduction was associated with significant improvements in the increase in pulse rate (13.8 +/- 5.8 at baseline vs -0.3 +/- 2.2 and 1.9 +/- 1.7; P < .05) as well as the increase in hematocrit level (4.0 +/- 1.4 at baseline vs 0.3 +/- 0.9. and 0.4 +/- 1.0; P < .05), and the lowest glycemia level in the OGTT (54.1 +/- 6.7 at baseline vs 98.9 +/- 7.1 and 67.8 +/- 5.9; P < .05). LAR octreotide administration significantly improved patients' quality of life. Patients' evaluations of their overall treatment efficacy was higher on LAR compared with the subcutaneous formulation (83% vs 52%; P = .01). Gallbladder stones occurred in 4 patients. CONCLUSIONS Monthly administration of LAR octreotide improves OGTT results, symptoms, and quality of life in patients with postoperative dumping.

Abstract
Unfortunately normal gastrointestinal function after an esophagectomy is rare. Most patients will never eat the way they did before their illness. Most patients require smaller more frequent meals. It is common for patients to loose up to 15% of their body weight from the time of diagnosis through the first 6 months postoperatively, but fortunately this trend levels off after 6 months. Dumping syndrome, delayed gastric emptying, reflux, and dysphagia can all contribute to nutritional deficiency and poor quality of life. There is no one surgical modification to eliminate any one of these complications, but several guidelines can help reduce conduit dysfunction. Most patients seem to benefit from a 5-cm-wide greater-curvature gastric tube brought up through the posterior mediastinum. The gastric-esophageal anastomosis should be placed higher than the level of the azygous vein. Drainage procedures seem to be helpful, especially when using the whole stomach as a conduit. Early erythromycin therapy significantly aids in the function of the gastric conduit. Proton-pump inhibitors are important for improvement of postoperative reflux symptoms and to help prevent Barrett's metaplasia in the esophageal remnant. Single-layer hand-sewn or semi-mechanical anastomoses provide greater cross-sectional area and fewer problems with stricture. When benign strictures occur, early endoscopy and dilation with proton-pump inhibition greatly reduces the morbidity. Patients should be instructed to eat six small meals a day and to remain upright for as long as possible after eating. Simple sugars and fluid at mealtime should be avoided until the function of the conduit is established.

Abstract
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.

Abstract
The dumping syndrome consists of early postprandial abdominal and vasomotor symptoms, resulting from osmotic fluid shifts and release of vasoactive neurotransmitters, and late symptoms secondary to reactive hypoglycemia. Effective relief of symptoms of dumping syndrome can be achieved with dietary modifications to minimize ingestion of simple carbohydrates and to exclude fluid intake during ingestion of the solid portion of the meal. More severely affected individuals may respond to agents such as pectin and guar, which increase the viscosity of intraluminal contents, or to drugs such as the alpha-glucosidase inhibitor acarbose, which blunts the rapid absorption of glucose, and the somatostatin analog octreotide, which alters gut transit and impairs release of vasoactive mediators into the bloodstream.

Abstract
Food intake is the simplest and most obvious measure of gastrointestinal function, yet it rarely receives more than cursory attention from surgeons. In this review we cover recent findings on relationships between gut function and appetite regulation mediated via neuropeptides influenced by afferent and efferent vagal activity. Evidence from the new discipline known as neurogastroenterology elucidates gastric and intestinal signals involved in the elicitation of hunger, satiety, and aversion. Discovery of the adipose-tissue-derived hormone, leptin, has energized the field of metabolism spawning increasing numbers of publications related to interactions between leptin and insulin release and glucose disposal, as well as appetitive behavior. Peptides such as cholecystokinin (CCK), the proglucagon-derived peptides, glucagon-like peptides 1 and 2 (GLP-1 and GLP-2), and the recently identified powerful intake-stimulating molecule, orexin, are examples of potential targets for drug development and studies of surgical pathophysiology. A major conclusion of this work is that the considerable redundancy and overlap between mediators of caloric intake subserving survival of the species, while beneficial after foregut surgery, contribute to the complexity of treating the global epidemic of obesity. Possibly knowledge derived from basic research in neurogastroenterology can translate into advances in surgical treatment of obesity.

Abstract
Dumping symptoms suggest concomitant sympathoadrenal activation. To evaluate the relation between dumping symptoms and postprandial plasma catecholamine changes, standardized dumping-provocation tests with use of oral glucose were performed for 16 gastric surgery patients with dumping, for 14 gastric surgery patients without dumping, and for 14 healthy control patients. Early dumping symptoms were present for all patients with dumping, and late symptoms developed in three patients with dumping after glucose ingestion. Patients without dumping and healthy control patients had slight complaints or no complaints. Systolic and diastolic blood pressure remained unaffected for the three groups. Positive breath-hydrogen tests, heart rate increments, and reactive plasma glucose decrements were present for patients with dumping and for patients without dumping, but not for control patients. Plasma noradrenaline and adrenaline increased for patients with dumping and for patients without dumping, but not for control patients. The noradrenaline increment was higher for patients with dumping (98%) than for patients without dumping (78%; p <0.05). The noradrenaline increment was related to the dumping score and to the heart rate increment for the first hour after glucose ingestion, whereas the adrenaline increment was related to the plasma glucose decrement for the third hour. Therefore, dumping symptoms clearly are accompanied by postprandial sympathoadrenal activation, but sympathoadrenal activation cannot account completely for development of dumping symptoms.

Abstract
BACKGROUND The aim of the study was to evaluate the new hormonal entity oxyntomodulin-like immunoreactivity in malabsorption states, and to assess its potential in celiac disease management. METHODS We measured basal and postprandial oxyntomodulin-like immunoreactivity values in 35 children divided into 3 groups: group 1 was composed of 13 children with celiac disease, either under a gluten-free diet (8 patients) or normal diet (5 patients); group 2 was composed of 8 children hospitalized for gastroenteritis or chronic diarrhea, without biological evidence of malabsorption nor abnormal jejunal mucosa; group 3 was composed of 22 control subjects. RESULTS Fasting and meal-stimulated levels in the control group were 71+/-10 and 130+/-26 pmol/l, respectively. Mean concentrations were elevated in patients with celiac disease (basal = 349+/-254 pmol/l, postprandial = 446+/-332 pmol/l) and in the group 2 (basal = 139+/-58 pmol/l, postprandial = 218+/-85 pmol/l), but the difference with control subjects did not reach statistical significance. In children with celiac disease, basal and stimulated values correlated with the degree of malabsorption as assessed by hemoglobin (p = 0.006 and p = 0.01, respectively) and serum folate concentrations (p = 0.03 and p = 0.02, respectively). CONCLUSIONS Oxyntomodulin-like immunoreactivity is noticeably higher in healthy children than previously measured in healthy adult subjects. This hormonal parameter is not an adequate diagnostic tool in celiac disease. Nevertheless, in the context of celiac disease, its elevation reflects the degree of malabsorption and may provide a quantitative approach of the extent of mucosal damage.

Abstract
UNLABELLED We describe a 17-month-old child with dumping syndrome after plication of the right diaphragm. He presented with periods of abdominal distension and pallor, recurrent convulsions, glucosuria and refusal of feeding. After changing the diet the symptoms disappeared. CONCLUSION Although dumping syndrome in children is rare, early recognition is important. Serial determination of blood glucose after bolus feeding can lead to the diagnosis. Treatment should consist of dietary changes.

Abstract
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.

Abstract
Severe long-term complaints of dumping occur in a small number of patients after gastric surgery. Dietary modification, fiber preparations, and medical therapy are often ineffective. In these severely affected patients administration of the somatostatin analog octreotide before meals appears to be a promising new strategy. The effects of octreotide on both gastrointestinal transit time and hormonal changes appear to contribute to the benefits seen in dumping syndrome. However, as the majority of studies conducted have employed only a single dose of octreotide, careful long-term assessment of the nutritional and metabolic effects will be required. Recent results suggest that octreotide may be administered up to 2 hr before a meal and therefore has a sufficiently long duration of action to be of practical long-term use. Moreover, general improvements in life-style, as well as beneficial effects on symptoms, have been reported with long-term treatment, although the potential development of diarrhea will require careful monitoring. The development of an oral or nasal formulation should further improve the practical application of octreotide as a treatment for dumping syndrome.

Abstract
Somatostatin, originally detected by Krulich and ultimately isolated by Brazeau, was initially described as a growth hormone release-inhibiting factor. Subsequent investigation into the use of native somatostatin and the development of long-acting somatostatin analogues, especially octreotide acetate, have fostered increasing uses of these compounds. Though the clinical and investigational uses of somatostatin and its analogues are varied, one central theme remains constant: the ability of these agents to suppress circulating peptide levels. This article, a review of the current non-endocrine applications of somatostatin and its analogues, covers a wide range of potential applications for somatostatin-like compounds. These include use in cirrhosis and variceal bleeding, peptic ulcer disease, pancreatic fistulas, acute and chronic pancreatitis, dumping syndrome, cancer therapy, small bowel fistulas, psoriasis, pain control, and autonomic hypotension. Somatostatin may also play a role in the development and potential treatment of neurologic disease and may have profound found influence on behavior.

Abstract
Fourteen patients with severe and persistent postvagotomy/postgastrectomy symptoms were entered into a trial of treatment with the somatostatin analogue octreotide, 50 micrograms twice daily 30 min before meals being self-administered by subcutaneous injection. Six of the seven patients completing the 3-month trial showed sustained overall improvement of symptoms. The remaining patients were unhelped by treatment or developed unwanted effects. Six of eight patients with dumping syndrome showed sustained improvement of dumping symptoms during treatment. Bile vomiting was relieved in three of four patients with this complaint. Diarrhoea accompanying dumping showed a variable response to treatment, with improvement in three patients and no change or worsening of this symptom in five. Two patients with severe postvagotomy diarrhoea alone showed no improvement. Four patients with unwanted effects and three patients who found no benefit stopped the trial medication early. Four further patients reported mild or transient side-effects. For patients with severe postvagotomy/postgastrectomy symptoms, a trial of octreotide seems justified when significant dumping symptoms are present and other treatment options have been exhausted.

Abstract
Postprandial glucagon-like peptide-1 (GLP-1), pancreatic glucagon, and insulin were measured in 27 tumor-free patients 43 months (median) after total gastrectomy and in four controls using a 99technetium-labeled 100-g carbohydrate solid test meal. Emptying of the gastric substitute was measured by scintigraphy. Fourteen patients suffered from early dumping symptoms, and five of them also reported symptoms suggestive of reactive hypoglycemia (late dumping). The median emptying half-time (T1/2) of the gastric substitute was 480 sec. Sigstad's dumping score was 8.5 +/- 1.6 (mean +/- SE) in patients with rapid emptying (T1/2 less than 480 sec), and 3.0 +/- 1.5 in patients with slow emptying of the gastric substitute (P = 0.02). The peak postprandial concentration of GLP-1 was 44 +/- 20 pmol/liter in controls, 172 +/- 50 in patients without reactive hypoglycemia, and 502 +/- 116 in patients whose glucose fell below 3.8 mmol/liter during the second postprandial hour. Plasma GLP-1 concentrations peaked at 15 min, and insulin concentrations at 30 min after the end of the meal. A close correlation between integrated GLP-1 responses and integrated insulin responses (r = 0.68) was observed. Multiple regression revealed that three factors were significantly associated with the integrated glucose concentrations during the second hour (60-120 min): Early (first 30 min) integrated GLP-1 (inverse correlation; P = 0.006), age (P = 0.006), and early integrated pancreatic glucagon (P = 0.005). There was a close (inverse) relationship of T1/2 with early integrated GLP-1 and pancreatic glucagon, but not with insulin. Gel filtration of pooled postprandial plasma of gastrectomized individuals revealed that all glucagon-like immunoreactivity eluted at Kd 0.30 (Kd, coefficient of distribution), the elution position of glicentin. Almost all of the GLP-1 like immunoreactivity eluted at Kd 0.60, the elution position of gut GLP-1. The authors contend that GLP-1-induced insulin release and inhibition of pancreatic glucagon both contribute to the reactive hypoglycemia encountered in some patients following gastric surgery. Rapid emptying seems to be one causative factor for the exaggerated GLP-1 release in these subjects.

Abstract
The various operations performed for the treatment of peptic ulcer disease can lead to a variety of iatrogenic disorders collectively referred to as the "postgastrectomy syndromes." Although the etiology of most of these disorders remains unclear, loss of vagal innervation and bypass, ablation, or destruction of the pylorus clearly are involved in the pathogenesis of most, if not all, of these disorders. Unfortunately, there often is also a poorly understood psychological element involved in the pathogenesis. Of all ulcer operations, proximal gastric vagotomy results in the fewest physiologic abnormalities and the mildest postoperative symptoms. The continued popularity of this operation should effect a marked reduction in the incidence of disabling postgastrectomy syndromes. Fortunately, symptoms severe enough to necessitate remedial operation are uncommon, and conservative medical management is always indicated and usually suffices. When disabling symptoms are refractory, a thorough evaluation of the patient and an accurate classification of the syndrome are essential to guarantee a satisfactory result from surgical intervention. Although numerous surgical procedures have been developed to deal with the different syndromes, with varied results, the Roux-en-Y procedure has emerged as the operation of choice for most, if not all, postgastrectomy syndromes. However, the Roux-en-Y procedure has not been universally successful, and this operation can itself lead to the recently recognized postgastrectomy state of Roux-en-Y stasis syndrome. Prevention therefore remains the best form of therapy, and remedial operation should not be undertaken until adequate time has elapsed since the original operation and all forms of conservative treatment have failed.

Abstract
Somatostatin and its longer-acting analog, octreotide acetate, can be used effectively for the treatment of nonendocrine gastrointestinal disorders. Octreotide has been shown to decrease pancreatic fistula output by suppressing exocrine pancreatic function. We believe that octreotide acetate may be useful to prophylaxis against the development of pancreatic fistulas following pancreatic resection and may reduce the enzymatic and volume output of established pancreatic fistulas. We also have shown that administration of octreotide acetate 2 hours before a high carbohydrate test meal reduces gut peptide levels, which increase following meal ingestion in patients with the dumping syndrome. Reduction of circulating peptides in these patients may slow gut motility and improve glucose regulation, thus, providing relief of postvagotomy dumping symptoms.

Abstract
The purpose of the study was to examine the gastrointestinal hormone responses to meals in morbidly obese patients before and after Roux-en-Y gastric bypass (GBP; n = 9) or vertical banded gastroplasty (VBG; n = 7). On consecutive days before and after operation, we measured changes in peripheral blood levels of glucose, insulin, enteroglucagon, serotonin, vasoactive intestinal polypeptide (VIP), and cholecystokinin (CCK) in response to a standardized glucose or protein-fat meal. The percentage of excess weight lost at 6 months after operation was 66.3% +/- 4% and 41.8% +/- 5% for GBP and VBG, respectively (p less than 0.01). The 3-hour integrated glucose response to a glucose meal decreased from 145.3 +/- 33.7 to 75.8 +/- 15.7 g min/L (p less than 0.02) after GBP. This was associated with a decrease in 3-hour integrated insulin response from 22.8 +/- 8.2 to 10.5 +/- 4.9 mU min/L. Vertical banded gastroplasty patients had lesser reductions of hyperglycemia and hyperinsulinemia. Neither the CCK, serotonin, nor VIP responses to meals were altered by either operation. The 3-hour integrated enteroglucagon response to glucose increased markedly in GBP patients after operation from 11.8 +/- 6 to 133.4 +/- 38 nmol min/mL (p less than 0.02). This increase in enteroglucagon occurred at the same time as development of dumping symptoms, which occurred exclusively in GBP patients after glucose but not protein. We conclude that (1) GBP surgery for morbid obesity results in amelioration of glucose intolerance and hyperinsulinemia, (2) CCK does not mediate an endocrine satiety effect of surgery, (3) GBP is associated with an exaggerated enteroglucagon response to glucose, and (4) enteroglucagon appears to be a marker of the dumping syndrome in GBP patients.

Abstract
Changes in blood flow in the celiac artery, superior mesenteric artery, and pancreas in response to an intravenous injection of synthetic human gastric inhibitory polypeptide (GIP) were determined simultaneously and continuously in anesthetized dogs, using a transit-time ultrasonic flowmeter and a laser-Doppler flowmeter. Injection of GIP significantly increased superior mesenteric arterial flow in a dose-related manner (by 9%, 43%, and 139% at 30 s after an injection at the doses of 3, 50, and 800 pmol/kg, respectively). In contrast, celiac arterial flow was not significantly altered by GIP at any of the three doses. Calculated vascular resistance in the superior mesenteric artery decreased after GIP infusion, whereas that in the celiac artery was not changed by GIP. Pancreatic blood flow decreased significantly after GIP injection at the doses of 50 and 800 pmol/kg (by 11% and 17%, respectively). Our data indicate that there is a substantial difference in the hemodynamic responses to GIP among splanchnic organs, and suggest that GIP acts specifically on the mesenteric vasculature.

Abstract
Gastric emptying of liquid was studied in 10 normal volunteers and in 27 patients previously treated with truncal vagotomy and drainage. Thirteen of the twenty-seven patients complained of persistent postvagotomy diarrhoea. For each study 300 ml 15 per cent dextrose, labelled with 99mTc-diethylene triamine penta-acetic acid (DTPA), was ingested at a standard rate by subjects who sat facing a gamma camera. Imaging proceeded for 30 min. Gastric area activity curves were corrected for emptying of the test meal during ingestion, and for movement using a new image alignment technique. Gastric emptying at 15 min was 10 +/- 2.6 per cent (mean +/- s.e.m.) in healthy volunteers, 48 +/- 7.3 per cent in patients without diarrhoea, and 84 +/- 2.3 per cent in those with diarrhoea (P less than 0.001, ANOVA). Gastric emptying from 15 min onwards was slower than normal in both patient groups (P less than 0.001). These results show that initial gastric emptying is rapid following truncal vagotomy and drainage, and this change is greater in patients with postvagotomy diarrhoea. No patient with diarrhoea had normal initial gastric emptying.

Abstract
In six patients suffering from severe early dumping and six patients with late dumping after peptic ulcer surgery, the effect of the somatostatin analogue SMS 201-995 was compared with placebo. In early dumpers subcutaneous administration of 50 micrograms SMS 201-995 prior to meal ingestion induced a strong improvement of dumping symptoms as reflected by a decrease of the Sigstad dumping score from 12 +/- 2 during placebo to 5 +/- 2 (p less than 0.05). Furthermore, the postprandial increase of pulse rate was abolished; maximum pulse rate decreased from 85 +/- 7 beats/min to 67 +/- 7 beats/min (p less than 0.05). SMS 201-995 did not significantly affect postprandial changes in packed cell volume. In late dumpers 50 micrograms SMS 201-995 reduced peak plasma insulin after oral glucose from 173 +/- 16 mU/L during placebo to 35 +/- 9 mU/L during SMS 201-995 (p less than 0.05) and increased individual plasma glucose nadirs from 1.9 +/- 0.3 mmol/L to 7.5 +/- 3.3 mmol/L (p less than 0.01). Both in early and late dumpers SMS 201-995 improved postprandial expiratory breath hydrogen excretion indicating slowing of gastrointestinal hurry. SMS 201-995 is a powerful therapeutic agent for the management of patients suffering from the dumping syndrome after gastric surgery.

Abstract
From 1973 to 1986, 22 patients underwent Roux-Y gastrojejunostomy for the early postgastrectomy dumping syndrome. In the early years, five patients underwent Roux-Y conversion with the addition of a 10 cm antiperistaltic jejunal segment interposed between the Roux-Y limb and the stomach. Within 4 years, all five patients had the jejunal segment removed due to severe symptoms of gastric retention. These patients underwent reconstruction to create Roux-Y limb only and joined the pool of 17 patients who underwent Roux-Y diversion only for the dumping syndrome. Overall, 19 of 22 patients (86 percent) had almost complete resolution of their dumping symptoms on long-term follow-up. Three patients showed no improvement, two with severe gastric retention and one with recurrent dumping symptoms. Overall, 5 of 22 patients (23 percent) had moderate to severe early and late postoperative gastric retention necessitating medical treatment in three and subsequent near-total gastrectomy in two. Although other procedures such as pyloric reconstruction or the addition of isoperistaltic or antiperistaltic jejunal interpositions have been reported to be equally successful in delaying gastric emptying and resolving dumping symptoms, we have preferred Roux-Y diversion for the treatment of combined alkaline reflux gastritis and dumping or the pure early vasomotor postgastrectomy dumping syndrome. As reported, we have abandoned the use of an antiperistaltic jejunal segment interposed between the stomach and the Roux-Y limb due to the high rate of postoperative gastric retention.

Abstract
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.

Abstract
The possibility that the gut peptide, neurotensin, may contribute to the dumping syndrome was investigated in 17 patients with a long history of dumping after a Billroth II gastrectomy for duodenal ulcer. After a test meal plasma levels of neurotensin were higher than in normal subjects, but no correlation to the severity of symptoms was found. In eight of the patients with meal-provoked dumping symptoms, intravenous infusion of neurotensin in relevant doses produced neither symptoms nor changes in blood glucose, blood pressure, or pulse rate. The apparent plasma half-life of neurotensin (t1/2 = 2.3 min) did not differ from that previously found in normal subjects. The results indicate that it is unlikely that neurotensin alone has a pathogenetic role in the dumping syndrome in gastrectomized patients.

Gastric emptying of a liquid meal was investigated with a radionuclide method before and 1 week and 3 and 12 months after gastroplasty operation for morbid obesity. Gastroplasty results in a small proximal pouch with a narrow stoma to the remaining stomach. The total gastric emptying was delayed 3 months after gastroplasty (p less than 0.01). Twelve months after gastroplasty, emptying of the proximal pouch was faster than at 3 months (p less than 0.01). This may indicate dilatation of the stoma between the two gastric pouches during this period. Surprisingly, the total gastric emptying 12 months after gastroplasty was not only faster than at 3 months but also faster than before surgery. The explanation, therefore, cannot only be attributed to a dilated stoma, and hormonal mechanisms may be involved. A lack of correlation between preoperative weight and emptying was observed, but because the material consists of only obese subjects, no conclusion can be drawn about the postulated role of gastric emptying in developing obesity. Emptying of the total stomach and of the proximal pouch failed to correlate with postoperative weight losses. The weight loss after gastroplasty evidently bears little, if any, relation to the postoperative changes in gastric emptying of liquids.
