Abstract
BACKGROUND In 2018 diagnostic criteria for pediatric intestinal pseudo-obstruction (PIPO) were established. Neuromuscular dysfunction of the gastrointestinal tract is one of these, and often examined through antroduodenal manometry (ADM). There is little data on antroduodenal manometries in children. Our objectives were to retrospectively apply these criteria to children evaluated for suspected motility disorder, to reevaluate the ADM patterns and compare children who did and did not meet the PIPO criteria and also with healthy adults. METHODS Children with a suspected gastrointestinal motility disorder previously investigated with 24-h 8-lead ADM were reevaluated by applying the 2018 ESPGHAN/NASPGHAN PIPO diagnostic criteria and the 2018 ANMS-NASPGHAN guidelines. ADM findings were compared between children who retrospectively fulfilled a PIPO diagnosis, children who did not, and a control group of healthy adults. KEY RESULTS Of 34 children (age 7.9 (±5.1) years, 18 males), 12 retrospectively fulfilled the 2018 PIPO diagnostic criteria. Twenty-five children (10 in the PIPO group) had abnormal diagnostic findings on ADM, whereas 9 (2 in the PIPO group) had no such findings. A PIPO diagnosis implied a significantly higher degree of abnormal ADM patterns (2.33 vs. 1.23, p = 0.02). There were no major differences in quantitative ADM measurements between the groups except higher pressures in children. CONCLUSIONS AND INFERENCES Children who retrospectively fulfilled a PIPO diagnosis had a significantly higher abundance of abnormal ADM findings compared with symptomatic children without PIPO and healthy adults. Our data indicate a need for set criteria for evaluation of ADM in children with suspected PIPO.

Abstract
BACKGROUND Upper gastrointestinal symptoms in children are common and motility disorders are considered in the differential diagnosis. High resolution esophageal manometry (HRM) has revolutionized the study of esophageal physiology, and the addition of impedance has provided new insights into esophageal function. Antroduodenal motility has provided insight into gastric and small bowel function. PURPOSE This review highlights some of the recent advances in pediatric esophageal and antroduodenal motility testing including indications, preparation, performance, and interpretation of the tests. This update is the second part of a two part series on manometry studies in children (first part was on anorectal and colonic manometry [Neurogastroenterol Motil. 2016;29:e12944]), and has been endorsed by the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) and the American Neurogastroenterology and Motility Society (ANMS).

Abstract
Altered motility remains one of the important pathophysiologic factors in patients with irritable bowel syndrome (IBS) who commonly complain of abdominal pain and stool changes such as diarrhea and constipation. The prevalence of IBS has increased among Asian populations these days. Gastrointestinal (GI) physiology may vary between Asian and Western populations because of differences in diets, socio-cultural backgrounds, and genetic factors. The characteristics and differences of GI dysmotility in Asian IBS patients were reviewed. MEDLINE search work was performed including following terms, 'IBS,' 'motility,' 'transit time,' 'esophageal motility,' 'gastric motility,' 'small intestinal motility,' 'colonic motility,' 'anorectal function,' and 'gallbladder motility' and over 100 articles were categorized under 'esophagus,' 'stomach,' 'small intestine,' 'colon,' 'anorectum,' 'gallbladder,' 'transit,' 'motor pattern,' and 'effect of stressors.' Delayed gastric emptying, slow tansit in constipation predominant IBS patients, rapid transit in diarrhea predominant IBS patients, accelerated motility responses to various stressors such as meals, mental stress, or corticotrophin releasing hormones, and altered rectal compliance and altered rectal accomodation were reported in many Asian studies regarding IBS. Many conflicting results were found among these studies and there are still controversies to conclude these as unique features of Asian IBS patients. Multinational and multicenter studies are needed to be performed vigorously in order to elaborate characteristics as well as differences of altered motililty in Asian patients with IBS.

Abstract
The electroenterogram (EEnG) is a surface recording of the myoelectrical activity of the smooth muscle layer of the small intestine. It is made up of two signals: a low-frequency component, known as the slow wave (SW), and high-frequency signals, known as spike bursts (SB). Most methods of studying bowel motility are invasive due to the difficult anatomic access of the intestinal tract. Abdominal surface EEnG recordings could be a noninvasive solution for monitoring human intestinal motility. However, surface EEnG recordings in humans present certain problems, such as the low amplitude of the signals and the influence of physiological interference such as the electrocardiogram (ECG) and respiration. In this study, a discrete estimation of the abdominal surface Laplacian potential was obtained using Hjorth's method. The objective was to analyze the enhancement given by Laplacian EEnG estimation compared to bipolar recordings. Eight recording sessions were carried out on eight healthy human volunteers in a state of fasting. First, the ECG interference content present in the bipolar signals and in the Laplacian estimation were quantified and compared. Secondly, to identify the SW component of the EEnG, respiration interference was removed by using an adaptive filter, and spectral estimation techniques were applied. The following parameters were obtained: the dominant frequency (DF) of the signals, stability of the rhythm (RS) of the DF detected and the percentage of DFs within the typical frequency range for the SW (TFSW). Results show the better ability of the Laplacian estimation to attenuate ECG interference, as compared to bipolar recordings. As regards the identification of the SW component of the EEnG, after removing respiration interference, the mean value of the DF in all abdominal surface recording channels and in their Laplacian estimation ranged from 0.12 to 0.14 Hz (7.3 to 8.4 cycles min(-1) (cpm)). Furthermore in 80% of the cases, the detected DFs were inside the typical human SW frequency range, and the ratio of frequency change in the surface bipolar and Laplacian estimation signals, in 90% of the cases, was within the frequency change accepted for human SW. Significant statistical differences were also found between the DF of all surface signals (bipolar and Laplacian estimation) and the DF of respiration. In conclusion, it was demonstrated that the discrete Laplacian potential estimation attenuated the physiological interference present in bipolar surface recordings, especially ECG. Furthermore, a slow frequency component, whose frequency, rhythm stability and amplitude fitted with the SW patterns in humans, was identified in bipolar and Laplacian estimation signals. This could be a useful non-invasive tool for monitoring intestinal activity by abdominal surface recordings.

Abstract
OBJECTIVE Altered small bowel motility and a high prevalence of small intestinal bacterial overgrowth (SIBO) has been observed in patients with liver cirrhosis. Our aim was to explore the relationship between motility abnormalities, portal hypertension, and SIBO. METHODS Twenty-four patients with liver cirrhosis were included. Twelve had portal hypertension (PH) and 12 had liver cirrhosis (LC) alone. Child-Pugh score was the same in the groups. Antroduodenojejunal pressure recordings were performed, and noninvasive variceal pressure measurements were undertaken. Thirty-two healthy volunteers served as a reference group. Bacterial cultures were obtained from jejunal aspirates. RESULTS The PH group had a higher proportion of individual pressure waves that were retrograde in the proximal duodenum during phase II (52% vs 13% vs 8% of propagated contractions; p < 0.001) as well as postprandially (49% vs 18% vs 13%; p < 0.01) compared with LC and controls, respectively. Long clusters were more common in PH than in controls (9.1 +/- 2.1 vs 4.9 +/- 0.8; p < 0.05), and a higher motility index in phase III in the proximal and distal duodenum was seen in the PH as compared with the other groups. The mean variceal pressure was 21 +/- 1 mm Hg. Motor abnormalities were not correlated to the level of variceal pressure. Thirty-three percent of the patients in the PH group but none in the LC group had SIBO. CONCLUSIONS Abnormal small bowel motility and SIBO is common in patients with liver cirrhosis with concomitant portal hypertension. Portal hypertension per se might be significantly related to small bowel abnormalities observed in patients with liver cirrhosis.

Abstract
BACKGROUND All gut movements are claimed to be activated essentially by the concentric contraction of the circular muscle, moving the chyme aborally. The role of the longitudinal smooth muscle of the small intestine in gut motility is poorly understood; this point was investigated in the current study. METHODS The abdomens of 14 crossbreed dogs (eight dogs, six bitches) were opened. A segment of the small intestine was distended by a balloon in increments of 2 mL of saline, and the pressure and electrical activity were recorded proximally and distally to the balloon. The gut wall around the balloon was anesthetized and the test was repeated. The longitudinal muscle coat of the small intestine segment was then excised, and the pressure response and electrical activity were recorded on ileal distension. RESULTS Two milliliter ileal distension produced pressure decrease (P < 0.05) proximally and distally to the balloon and caused balloon movement. Four, 6 and 8 mL distension effected similar pressure response, while 10 mL showed no response. Electrical waves were recorded from the three electrodes applied to the ileal segment. Upon ileal distension, electrical activity increased over the distended area, with no activity proximally and distally to it. Balloon distension of the anesthetized ileal segment produced no pressure response or electrical activity. After longitudinal myectomy, no electrical activity was recorded at rest or upon ileal distension, and the balloon did not move. CONCLUSION Ileal distension initiated circular muscle contraction only in the presence of the overlying longitudinal muscle, which appears to transmit the electrical activity to the circular muscle upon ileal distension. Ileal contraction is suggested to initiate ileal hypotonia in the proximal and distal ileal segments mediated through an 'ileo-ileal inhibitory reflex' that leads to aboral progress of the proximally and distally located chyme.

Abstract
Diabetic gastropathy is a term that encompasses a number of neuromuscular dysfunctions of the stomach, including abnormalities of gastric contractility, tone, and myoelectrical activity in patients with diabetes. These abnormalities range from tachygastrias to antral hypomotility and frank gastroparesis. Diabetic gastropathies may be acutely produced during hyperglycemia. Symptoms of chronic diabetic gastropathy include chronic nausea, vague epigastric discomfort, postprandial fullness, early satiety, and vomiting. Because these symptoms are nonspecific, other disorders such as mechanical obstruction of the gastrointestinal tract, gastroesophageal reflux disease, cholecystitis, pancreatitis, mesenteric ischemia, and drug effects should be considered. Neuromuscular abnormalities of the stomach may be assessed noninvasively with gastric emptying tests, electrogastrography, and ultrasound. Gastrokinetic agents such as metoclopramide, cisapride, domperidone, and erythromycin increase fundic or antral contractions and/or eradicate gastric dysrhythmias. Diet and glucose control also are important in the management of diabetic gastropathy. As the pathophysiology of diabetic gastropathy is better understood, more specific and improved treatments will evolve.

Abstract
For many patients, nutritional support and relief of symptoms remain the primary management goal of pseudo-obstruction. Specific pharmacological agents for this disorder are, in general, lacking. Given that the efficacy of many of the individual available agents is far from excellent, several centers have turned to combination therapy. Though there is at present no evidence from controlled studies to support this strategy, it is, at the very least, theoretically attractive as these agents act through a number of separate mechanisms. The combination of a prokinetic and an emetic may prove especially useful. As the pseudo-obstruction syndromes are, individually, rare, and experience with any given prokinetic agent in these disorders limited, it is difficult to develop strict guidelines for their use in this context. It stands to reason that a response to a prokinetic agent would seem unlikely in a patient with an advanced myopathic process; anecdotal evidence suggests, however, that some patients with severe scleroderma may derive some symptomatic improvement. Where oral therapy is tolerated, cisapride would appear the best choice among available agents. When this fails, subcutaneous octreotide may be added or substituted. In the acute situation, intravenous erythromycin may alleviate gastroparesis, but probably exerts little beneficial effect beyond the pylorus; parenteral metoclopramide may be tried, but, here again, convincing evidence of efficacy is lacking. The roles of endoscopy and surgery are largely confined to facilitating nutrition and providing decompression.

Abstract
This review focuses on current aspects of the novel technology of multiple intraluminal electrical impedance measurement. It presents methodological features, summarizes current results, and discusses potential implications for further research. The impedance technique assesses a bolus transport and its associated peristalsis. Validation studies showed a good analogy between physically deduced impedance characteristics and characteristics derived from cineradiography and manometry. From the impedance tracings, it is possible to distinguish between resting states, bolus transit, and wall contraction. Characteristics of a peristaltic wave can be obtained. In human studies, esophageal and small intestinal peristaltic patterns can quantitatively and qualitatively be assessed. A high resolution recording of bolus movements with interesting details of transport and mixing can be obtained. On the basis of several prior characterized impedance tracings duodenal contractile patterns have been classified, and the interdigestive and postprandial states characterized. For reflux evaluation the impedance technique was especially useful for the detection of nonacid gastroesophageal reflux, which is not detectable by pH monitoring. In summary, the main impact of the impedance technique is its capability to characterize esophageal and intestinal chyme transport. Important data on luminal chyme transport have been obtained. This technique is developing into an interesting investigative tool to complement standard techniques for study of upper GI motility, in particular for basic research.

Abstract
During recent years there has been increasing evidence for extraoesophageal dysfunction in achalasia. The aim was to investigate whether motility of the small intestine is abnormal in achalasia. Thirteen patients (eight men, five women) aged 52 (33-85) years were studied. They had all previously undergone treatment with pneumatic balloon dilatation and were free of dysphagia when examined. Ambulatory 24-h motility was recorded in the upper jejunum under standardized caloric intake with a digital datalogger and catheter-mounted pressure transducers located beyond the ligament of Treitz. Visual analysis was performed by two observers and data underwent quantitative analysis of phasic contractile events using a computer program. Normal values were obtained from 50 healthy controls. In the fasting state, a complete loss of cyclic MMC activity (n = 2), an abnormally prolonged phase II (n = 2) and disturbances in the aboral migration of phase III (n = 5) were observed. Postprandial motor response was absent (n = 2) or frequently showed a contraction frequency below the normal range (n = 5). Further abnormalities consisted in hypomotility during phase II (n = 3) and in a reduced frequency of migrating clustered contractions in the fasting (n = 2) or postprandial state (n = 2). In addition, motor events not present in any healthy subject, giant migrating contractions (n = 5), retrograde clustered contractions (n = 6) and repetitive retrograde contractions (n = 3) were identified. Each patient exhibited findings out of the range of normal. Dysmotility of the proximal small intestine is present in achalasia.

Abstract
The migrating motor complex (MMC) shows large variations within an individual and between individuals. This study aimed to investigate, with respect to this variability, the importance of gastric or duodenal origin of phase III activity. Interdigestive 6- to 10-h stationary antroduodenal motility recordings of 19 healthy male subjects were analyzed for MMC cycle durations and duration of phases I, II, and III, all with respect to the place of origin of each phase III. Data are given for the duodenal recording site as means +/- SE. Mean MMC cycle duration was 117.3 +/- 13.9 min, regardless of the place of origin of phase III. Seventy-two phase III cycles were observed in total, 35 and 37 starting in the "antrum" and duodenum, respectively. After a phase III of "antral" origin, MMC cycle duration was 156.1 +/- 11.0 min, significantly longer than MMC cycle duration following a phase III of duodenal origin, 80.5 +/- 10.7 min (P < 0.001). Phase III duration was longer when of "antral" origin than when starting in the duodenum (7.6 +/- 0.4 and 5.3 +/- 0.4 min, respectively; P < 0.001). MMC cycle duration and duration of phases I, II, and III depend on the place of origin of phase III ("antral" or duodenal) and on the origin of the preceding phase III. This factor explains part of the MMC variability observed within individuals. Mean MMC cycle duration in healthy subjects or patients should therefore also include information on the origin of phase III.

Abstract
Antroduodenal manometry has been used to determine the pathophysiology associated with signs and symptoms of gastrointestinal motility disorders. The diagnostic value of antroduodenal manomentry has been limited by the paucity of data from normal children. In this study, we compared antroduodenal manometry findings from 95 patients with symptoms suggesting a gastrointestinal motility disorder to 20 control children. Phase III of the migrating motor complex (MMC) was less frequent in patients (P < 0.05), especially in those who required total parenteral nutrition (P < 0.001), than in controls. Abnormal migration of phase III and short intervals between phase IIIs were more frequent in patients than in controls (P < 0.01 and P < 0.05, respectively). During phase II, persistent low-amplitude contractions and sustained tonic-phasic contraction were found only in parenteral-nutrition-dependent children. Short or prolonged duration of phase III, absence of phase I following phase III, tonic contractions during phase III, low amplitude of phase III contractions in a single recording site and clusters of contractions or prolonged propagating contractions during phase II were not more frequent in patients than in controls. We conclude that there are five manometric features having a clear association with pediatric gastrointestinal motility disorders: (1) absence of phase III of the MMC, (2) abnormal migration of phase III, (3) short intervals between phase III episodes, (4) persistent low-amplitude contractions, and (5) sustained tonic-phasic contractions.

Abstract
BACKGROUND Few data are available on adaptive changes of human small bowel motility after intestinal resection. AIM To characterise jejunal motility after extensive and limited distal intestinal resection. METHODS Seven patients with a short bowel syndrome after total ileal and partial jejunal resection (residual jejunal segments between 60 and 100 cm) and six patients with limited distal ileal resection (resected segment between 30 and 70 cm) underwent ambulatory 24 hour jejunal manometry 15 (6-24) months after the operation. Normal values were obtained from 50 healthy subjects. Fasting motility and the motor response to a 600 kcal solid meal were analysed visually and by a computer program. RESULTS Limited ileal resection did not result in changed jejunal motility. After extensive distal resection, patients had a significantly shorter migrating motor complex (MMC) cycle and a significantly shorter duration of the postprandial motor response compared with controls (p < 0.005). Intestinal resection had no influence on jejunal contraction frequency and amplitude and did not lead to any abnormal motor pattern. CONCLUSION Extensive distal resection of the small intestine produces distinct abnormalities of fasting and postprandial motility in the intestinal remnant. The shortening of digestive motility and the increased frequency of MMC cycling could contribute to malabsorption and diarrhoea in the short bowel syndrome.

Abstract
BACKGROUND Whether small-bowel motility is abnormal in the irritable bowel syndrome (IBS) is a controversy at present. The aim of our study was to compare ambulatory long-term jejunal motility in 35 IBS patients with predominant diarrhea to normal values obtained in 50 healthy controls. METHODS Twenty-four-hour motility was recorded in the proximal jejunum with a portable datalogger and tube-mounted miniature pressure sensors. Fasting motility in the waking (W) and sleeping (S) state and the motor response to a standardized evening meal of 600 kcal underwent visual and computer-aided analysis. RESULTS Fasting motility in patients showed migrating motor complex (MMC) cycles of normal length and composition. Uninterrupted runs of discrete clustered contractions during phase II (W) occurred in 57% of patients and 52% of controls but had a significantly longer duration in patients (33 +/- 5 versus 19 +/- 7 min; p < 0.005). During phase II (W) IBS patients had an increase in aborally propagated contractions (41 +/- 2% versus 35 +/- 2%; p < 0.01) and higher contraction amplitudes (26.3 +/- 0.8 versus 23.0 +/- 0.5 mm Hg; p < 0.01). Similar differences were obtained during postprandial motility (47 +/- 3% versus 39 +/- 3%; p < 0.01, and 25.9 +/- 0.9 versus 23.8 +/- 0.05 mm Hg; p < 0.02). In three patients (8.6%) disturbed aboral migration of phase III and irregular burst activity, manometric features of chronic idiopathic intestinal pseudo-obstruction, were identified. Whereas 57% of patients had an entirely normal 24-h manometry, 43% had at least one finding not present in any healthy control. CONCLUSION Small-intestinal motility is frequently but not universally abnormal in diarrhea-predominant IBS. The abnormal manometric findings are heterogeneous and range from subtle quantitative changes to severe qualitative abnormalities resembling chronic idiopathic intestinal pseudo-obstruction in a small subset of patients.

Abstract
AIMS/METHODS In 30 patients with functional dyspepsia and in 20 healthy volunteers, ambulatory duodenojejunal manometry was performed to examine the interdigestive and postprandial small intestinal motility patterns in relation to symptoms. RESULTS In the fasting state, the number of migrating motor complex cycles mean (SEM) was significantly lower in patients, especially in patients with dysmotility-like dyspepsia, than in control subjects (3.8 (0.4), 2.6 (0.5), and 5.3 (0.7) cycles, respectively; p < 0.05), due to a longer duration of phase II. Non-propagated and retrogradely propagated phase III activity was more prevalent in patients than in control subjects (48% v 15%; p = 0.020). During phase II and after dinner no differences were found in contraction incidence, mean amplitude or motility index. However, 1 1/2 hours after completing breakfast the motility index was higher in patients at all three recording levels (p < 0.05). Burst activity was more prevalent in patients than in control subjects (22% v 6% of the subjects; p = 0.003). In 41% of the patients the symptom index was > 75%. CONCLUSIONS These results suggest that small intestinal motor abnormalities, especially during fasting, participate in the pathogenesis of symptoms in patients with functional dyspepsia. Ambulatory manometry of the small intestine is a valuable tool to demonstrate these abnormalities in outpatients pursuing their daily activities.

Abstract
Although symptoms possibly related to motor dysfunction appear to be common, primary disorders of the foregut motor apparatus, defined on the basis of a discrete myoneural pathology, are notably rare. This phenomenon may as much reflect the relatively primitive nature of diagnostic methods as the true rarity of such disorders. Although diagnostic methodologies increase in sophistication and availability, their clinical impact has been limited by an imperfect relationship between symptoms and dysfunction and by a relatively poor ability of such tests to predict response to available therapeutic strategies. An ever-increasing understanding of the complex, often interrelated motor and sensory phenomena that contribute to symptoms, together with the development of consensus on the use and interpretation of motility tests and the more widespread application of sophisticated histologic, immunologic, biochemical, and molecular biologic methodologies to the study of these disorders, should lead, in the years to come, to much needed progress in this area.

Abstract
The human migrating motor complex (MMC) and sleep cycle have a similar periodicity, and there is some contention as to whether these biorhythms are linked. In irritable bowel syndrome (IBS), episodes of intestinal dysmotility have been described almost exclusively during wakefulness, but IRS patients often complain of poor sleep, and it has been suggested that IBS patients have increased rapid eye movement (REM) sleep. This study sought to identify any associations between sleep stage and small intestinal motility and any objective sleep abnormalities in IBS. Nocturnal motility was recorded from six small intestinal sensors mounted on a fine nasoenteric catheter in eight IBS patients and 10 healthy volunteers. Polysomnography to determine sleep stage was recorded simultaneously. The proportions of time awake, in non-REM and REM sleep was similar in controls and IBS. REM latency did not differ between the two groups despite increased depression in the IBS patients (Hamilton Depression Rating of 8.3 +/- 1.7 in IBS, 3.0 +/- 0.7 in controls, P < 0.01). Nocturnal motility was similar, with phase I occupying most of the MMC cycles. There was no temporal association between MMCs and sleep stage, with no synchrony of phase III for REM episodes. The mean motility index of 4.5 +/- 0.4 during wakefulness was greater than during all sleep stages (P < 0.05). During non-REM sleep stages 1 and 2, motility index of 3.2 +/- 0.3 was greater than 2.3 +/- 0.2 during stages 3 and 4 (P < 0.05), but similar to motility index of 3.3 +/- 0.4 during REM sleep. This sleep architecture and nocturnal small intestinal motility are normal in IBS.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Two children were thought to have an atypical gastroduodenal motility disorder because of the history and clinical course; both had received parenteral alimentation because of claims of inability to tolerate enteral feedings, and both continued to have unusual medical problems during parenteral alimentation. Both children had motility studies that were interpreted by a pediatric gastroenterologist to be "abnormal" and "diagnostic" of a motility disorder, but each was eventually shown to have a behavioral abnormality related to Munchausen syndrome by proxy.

Abstract
BACKGROUND Ambulatory long-term manometry is increasingly being used to study small-bowel motility. This study aimed to develop computer-aided data analysis including the elimination of artefacts, identification of individual phasic contractions, and analysis of aboral propagation. METHODS Data processing included low-pass filtering, base-line adaptation, cross-comparison of channels, and application of threshold values for contraction parameters. Automated analysis was validated by a visual reference standard. RESULTS Artefacts were related to cardiovascular and respiratory activity, changes in body posture, and contractions of the abdominal wall. Automated recognition of contractions reached a sensitivity of 92% and a positive predictive value of 88% compared with the visual standard. Mean contraction amplitude and duration of computer analysis were 96% and 93%, respectively, of the visually obtained values. Propagation analysis under ambulatory conditions showed good agreement with previous results by stationary recordings. CONCLUSIONS Computerized analysis provided valid and reproducible data on small-bowel phasic contractile events and propagative activity by digital long-term manometry.

Abstract
No study to date has objectively investigated whether the motor behavior of the small bowel is abnormal in celiac sprue. The purpose of this study was to systematically address this topic by means of intraluminal pressure recordings in a series of such patients. Sixteen subjects (nine adults, seven children, age range 2-69 years) with celiac sprue were recruited and studied while untreated. Manometric examination was carried out for 6 hr during fasting and 3 hr after a meal. Adult celiac patients displayed a significantly (mean +/- SEM) greater frequency of migrating motor complexes in comparison to controls during fasting (4.44 +/- 1.6 vs 2.45 +/- 0.20, P < 0.01), whereas no differences were found in the pediatric group with respect to this variable. Fasting motor abnormalities, chiefly represented by discrete clustered contractions, giant jejunal contractions, and bursts of nonpropagated contractions, were discovered in a high percentage in both groups of celiac subjects (89% in adults and 44% in children, respectively). Similar abnormalities were observed in the postprandial period, especially in adults. In conclusion, patients with celiac sprue frequently display discrete gastrointestinal motor abnormalities, which though perhaps nonspecific may account for several symptoms complained of by such patients.

Abstract
Anorexia nervosa is considered one type of eating disorder that may result in severe malnutrition. Patients with this disorder commonly complain of postprandial nausea, abdominal pain, and distension. We describe the radiologic and motility abnormalities associated with anorexia nervosa in a 21-year-old female. Barium gastrointestinal series demonstrated marked dilation of the duodenum, with prolongation of intestinal transit. A 4-hr fasting gastroduodenal motility study showed no propagating migrating motor complexes (MMC). Prolonged, but nonpropagating, bursts of high-amplitude phasic and tonic contractions were seen in the duodenum. In contrast, antral contractions were of low amplitude and esophageal motor function was normal. Metoclopramide and edrophonium caused an increase in gastroduodenal motor activity, but increased contractions were not associated with symptoms. Following a renutrition program that raised the patient's weight from 64 to 80% of her ideal body weight, the radiographic abnormalities and gastrointestinal dysmotility resolved completely. These observations suggest that anorexia-associated gastrointestinal motor dysfunctions are a consequence, not the cause of the generalized protein-calorie malnutrition associated with anorexia nervosa. The facts that motility in different parts of the gut is affected to different degrees and that gastric and duodenal muscle responds normally to exogenous stimulation argue against a generalized myogenic dysfunction and, rather, point to a reversible dysfunction of neural regulation.

Abstract
The effects of cisapride, given orally at standard therapeutic dosage (10 mg tds), on proximal small bowel interdigestive motility in ten healthy volunteers was assessed by prolonged ambulatory manometry. Cisapride did not alter the duration of the MMC cycle, duration of phase II or the propagation rate of phase III in either the daytime or nighttime periods. However, when compared to studies, in which subjects received no drug, both nighttime and daytime phase II mean contractile amplitude, but not contractile incidence, were significantly increased (P < or = 0.001) by cisapride. Cisapride significantly increased the incidence of distally propagated clustered activity. We conclude that the major effects of cisapride on healthy small bowel motor function is to increase the mean contractile amplitude and incidence of distally propagated clustered activity.
