Thickening of the internal anal sphincter in idiopathic constipation in children.

Thickening of the internal anal sphincter (IAS) is observed in chronic idiopathic constipation (IC) and solitary rectal ulcer syndrome (SRUS), where it has been correlated with the presence and severity of rectal intussusception. Alternatively, thickened IAS may be a feature of the obstructed megarectum in a similar way to the hypertrophy of bladder neck seen in dyssynergic bladders. The aim of this study was to investigate the significance of thickening of the IAS in children with chronic IC and to determine any association between the thickened IAS and anorectal manometry findings and patient's symptoms. A total of 144 children were admitted for investigations and treatment of chronic IC and evaluated prospectively between April 2001 and April 2003. IAS thickness was measured by endosonography using B&K axial endosonic probe type 1850 with a 10-MHz rotating transducer. The thickness of IAS was measured at 3, 6, and 9 o'clock, and the mean value of the three measurements was used for analysis. Functional assessment was done by anorectal manometry pressure studies under ketamine anaesthesia. A validated symptom score (SS) was used to assess the severity of symptoms. The sum of SS ranged between 0 and 65. Spearman's rho two-tailed test was used to correlate the thickness of IAS with patients' symptoms and anorectal manometry findings. Results were expressed as median and range and p-value of less than 0.05 was considered significant. Of 144 children, 84 were boys, median age 8.1 years (range 3.1-15). Soiling was present in 137 (94%) patients, delay in defecation in 132 (91%), and a palpable megarectum on abdominal examination in 117 (80%). The median duration of symptoms and duration of laxative treatment were 4 years (range 0.3-14.5) and 3.3 years (0.2-13.5), respectively. The average severity score for soiling, delay in defecation, palpable megarectum, and the total SS were 8 (range 0-10), 5 (0-10), 2 (0-12), and 33 (11-51), respectively. The median thickness of IAS was 0.9 mm (range 0.3-2.8) and the median resting anal sphincter pressure was 54 mmHg (19-107). The median amplitudes of rectal and anal sphincter contraction were 3 mmHg (1-25) and 9 mmHg (1-35), respectively. The thickness of IAS correlated significantly with total symptom severity score (r=0.31, p=0.0001), soiling score (r=0.28, p=0.001), megarectum score on abdominal palpation (r=0.29, p=0.001), size of megarectum on manometry (r=0.36, p=0.0001), amplitude of rectal contraction (r=0.23, p=0.007), and age of patient (r=0.55, p=0.0001). There was also a significant correlation between the amplitude of rectal and anal sphincter contraction (r=0.32, p=0.0001). There was no correlation between thickness of IAS and resting anal sphincter pressure and amplitude of anal sphincter contraction on anorectal manometry study. A total of 24 children had myectomy of thickened and overactive IAS in addition to the medical treatment of their chronic IC. The histology examination of myectomy specimen with eosin and haematoxylin staining and histochemical acetylcholine esterase staining showed smooth muscle fibres and ganglion cells. Thickening of IAS correlates significantly with duration and severity of symptoms, size of megarectum, and amplitude of rectal contraction. The pathogenesis is secondary to the continuous presence of faeces in the rectum, resulting in chronic abnormal stimulus to the IAS, which leads to hypertrophic changes in the rectum wall and IAS.

Impaired esophageal function in morbidly obese patients with gastroesophageal reflux disease: evaluation with multichannel intraluminal impedance.

BACKGROUND: Morbid obesity is associated with gastroesophageal reflux disease (GERD), and both have an independent association with motility disorders. Impaired esophageal function is thought to play a role in the development of dysphagia after fundoplication and bariatric procedures (especially restrictive procedures). The authors aimed to define both the physiology and the underlying pathophysiology of swallowing using a novel technique, multichannel intraluminal impedance (MII), which can accurately determine the clearance of a swallowed bolus through the esophagus, in combination with traditional manometry, which can measure peristalsis. METHODS: Simultaneous MII, manometry, and pH monitoring were performed for 10 asymptomatic subjects, 22 consecutive nonobese patients with GERD (GERD), and 22 consecutive morbidly obese patients with GERD (MO-GERD) who were under evaluation for antireflux and bariatric surgery at the University of Washington. In this study, MII was defined as abnormal if less than 80% of swallowed liquid boluses cleared the esophagus completely. RESULTS: All GERD and MO-GERD patients had abnormal pH monitoring. The manometric findings were similar for the GERD and MO-GERD patients. All the asymptomatic subjects had normal manometry and impedance test results. Abnormal manometry would have predicted that approximately 23% of GERD and MO-GERD patients had defective emptying. However, when measured with impedance, esophageal clearance was found to be defective in two times as many GERD and nearly three times as many MO-GERD patients. CONCLUSIONS: In patients with GERD, impedance often detects impairments in esophageal motility not identified by manometry. Morbidly obese patients with GERD have a higher incidence of impaired esophageal motility than nonobese patients with GERD. This may have implications for bariatric procedures, especially those that are restrictive.

Impact of referral for gastro-oesophageal reflux disease on the workload of an academic Gastroenterology Unit.

BACKGROUND: Gastro-oesophageal reflux disease is known to be a frequent cause of patients' referral to hospital gastroenterologists. AIM: To increase knowledge on referral for reflux disease, in an Italian academic setting. PATIENTS AND METHODS: The impact of gastro-oesophageal reflux disease on 1 year's workload, comprising upper endoscopy, outpatients' consultations in the general clinic, oesophageal pH monitoring and oesophageal manometry was retrospectively assessed. Appropriateness of oesophageal pH monitoring and oesophageal manometry was also evaluated. RESULTS: Endoscopy: Out of 2269 upper endoscopies reflux symptoms comprised 16.9% (n=386) of referrals; 19.1% only of these 386 patients had erosive oesophagitis at endoscopy and none had oesophagogastric malignancies (68% of the patients were >45 years). Consultations: Thirty-three percent out of 553 patients were referred for reflux symptoms. Upper endoscopy had already been performed before consultation in 64% of them. pH monitoring and oesophageal manometry: Two hundred and sixteen oesophageal pH monitorings and 160 oesophageal manometries were performed and 29% and 28%, respectively, were inappropriate, being performed in the diagnostic work-up of patients with typical reflux symptoms. CONCLUSIONS: At an academic Gastroenterology Unit, (a) gastro-oesophageal reflux disease is a frequent referral for upper endoscopy and consultations, (b) prevalence of oesophagitis is low, (c) consultation is preceded by endoscopy in the majority of patients and (d) oesophageal pH monitoring and oesophageal manometry are often inappropriately used.

'Pole test' measurements in critical leg ischaemia.

BACKGROUND: For the quantification of critical limb ischaemia (CLI) most vascular surgery units use sphygmo-manometric and transcutaneous oxygen pressure (TcPO2) measurements. However, measurements obtained by cuff-manometry can be overestimated especially in diabetic patients because of medial calcification that makes leg arteries less compressible. TcPO2 measurements present a considerable overlap in the values obtained for patients with different degrees of ischaemia and its reproducibility has been questioned. Arterial wall stiffness has less influence on the pole test, based on hydrostatic pressure derived by leg elevation, and this test seems to provide a reliable index of CLI. OBJECTIVE: The objective of this study was to evaluate the pole pressure test for detection of critical lower limb ischaemia, correlating results with cuff-manometry and transcutaneous oxygen pressure. DESIGN: University hospital-prospective study. MATERIALS AND METHODS: Seventy-four patients (83 legs) with rest pain or gangrene were evaluated by four methods: pole test, cuff-manometry, TcPO2 and arteriography. CLI was present if the following criteria were met: (a) important arteriographic lesions+rest pain with an ankle systolic pressure (ASP) < or = 40 mmHg and/or a TcPO2 < or = 30 mmHg, or (b) important arteriographic lesions+tissue loss with an ASP < or = 60 mmHg and/or a TcPO2 < or = 40 mmHg. Fifty-seven lower limbs met the criteria for CLI. RESULTS: Measurements obtained by cuff-manometry were significantly higher to those obtained by pole test (mean pressure difference: 40 mmHg, p<0.001). The difference between the two methods remained statistically significant for both diabetics (50.73, p<0.001) and non-diabetics (31.46, p<0.001). Mean TcPO2 value was 15.51 mmHg and there was no important difference between patients with and without diabetes. Overall, there was a correlation between sphygmomanometry and pole test (r = 0.481). The correlation persisted for patients without diabetes (r = 0.581), but was not evident in patients with diabetes. Correlation between pole test and TcPO2 was observed only for patients with diabetes (r = 0.444). There was no correlation between cuff-manometry and TcPO2. The pole test offered an accuracy of 88% for the detection of CLI. The sensitivity of this test was 95% and the specificity 73%.

A normal gastrointestinal motility excludes chronic intestinal pseudoobstruction in children.

Gastrointestinal manometry has gained wide acceptance in the approach to patients with suspected enteric neuromuscular disorders. However, performing gastrointestinal manometry in these subjects without a previous exhaustive diagnostic evaluation is unjustified. Twelve children (median age: 7.0 years; range: 8 months-13 years), with clinical and x-ray features suggesting chronic intestinal pseudoobstruction, were referred to our unit for gastrointestinal manometry. The latter was performed with a perfused catheter for 5 hr in the fasting state and for 90 min after feeding. Data were compared with those recorded in eight age-matched controls. In all patients and controls, interdigestive motor complexes with propagated phases III were detected; a regular postprandial antroduodenal motor activity was also recorded. Patients and controls did not differ for fed antral and duodenal motility indexes, fed antroduodenal coordination, and length of duodenal phase III. Most of the patients showed short or prolonged bursts of nonpropagated activity in the fasting and/or fed states; in four cases fasting and/or fed sustained phasic activity was recorded. Manometric evidence of migrating motor complexes and postfeeding activity did not support the diagnosis of intestinal pseudoobstruction and suggested redirecting the diagnostic evaluation. Final diagnoses were: Munchausen syndrome-by-proxy (four cases), celiac disease (two cases), intestinal malrotation (two cases), Crohn's disease (two cases), multiple food intolerance (one case), and congenital chloride-losing diarrhea (one case). It is concluded that in children with suspected chronic intestinal pseudoobstruction manometric evidence of migrating motor complexes and fed motor activity excludes an enteric neuromuscular disorder and suggests a reassessment of the diagnostic work-up. Furthermore, if gastrointestinal manometry shows migrating motor complexes and postfeeding motor activity, qualitative abnormalities of the manometric tracings do not indicate an underlying enteric neuromuscular disorder and must not be overemphasized. Patients referred for gastrointestinal manometry should previously undergo an extensive diagnostic investigation to exclude disorders mimicking chronic intestinal pseudoobstruction.

Colonic motility in children with repaired imperforate anus.

Following surgical correction of imperforate anus, voluntary bowel control is frequently poor because of abnormal anorectal function. Using colonic manometry we investigated the role of colonic motility in the pathogenesis of fecal soiling in children following imperforate anus repair. Thirteen children with repaired imperforate anus and fecal soiling underwent motility testing 2-12 years after anoplasty. All had fecal incontinence unresponsive to conventional medical treatment. Colonic manometry was performed using water-perfused catheters. Anorectal manometry was undertaken in 10 patients. Motility study results, treatment and outcomes were compared. All patients had high-amplitude propagating contractions (HAPCs) with an average of 80% propagation into the neorectum. There was no correlation between HAPC number or morphology and any variable. Internal anal sphincter resting pressure was low in 6/10 patients. Relaxation of the internal anal sphincter was present in 6/10 children. Only 1 of 5 patients able to cooperate was capable of generating a normal maximal squeeze pressure. Therapeutic regimens were changed in 11 patients with clinical improvement in five. Fecal soiling in patients with repaired imperforate anus is a multifactorial problem including propagation of excessive numbers of HAPCs into the neorectum as well as internal anal sphincter dysfunction. Colonic manometry in conjunction with anorectal manometry aids in the understanding of the pathophysiology of fecal soiling and guides clinical management in children with repaired imperforate anus.

Anal vector volume analysis complements endoanal ultrasonographic assessment of postpartum anal sphincter injury.

BACKGROUND: The aim of this study was to determine the role of anal vector manometry in the assessment of postpartum anal sphincter injury and to establish the most suitable method of anal vector volume analysis for identifying significant external anal sphincter (EAS) injury in an at-risk parous population. METHODS: A total of 101 consecutive women with a history of instrumental or traumatic vaginal delivery was recruited. Anal ultrasonography and anal vector manometry were performed. Receiver-operator characteristic curves were used to determine the usefulness of anal manometry and anal vector volume analysis in the identification of significant EAS disruption (full thickness, more than one quadrant involved) detected by ultrasonography. RESULTS: Seventeen women had significant EAS disruption identified by anal ultrasonography. Anal vector manometry provided complementary functional information. Anal vector symmetry index (VSI), determined by analysis of mean maximum squeeze pressure, yielded 100 per cent sensitivity for significant EAS disruption, with a positive predictive value of 61 per cent. CONCLUSION: Anal vector manometry complements endoanal ultrasonography. VSI, determined by means of the squeeze pressure profile, correlates best with significant EAS disruption identified at anal ultrasonography.

The diagnostic value of oesophageal radionuclide transit in patients admitted for but without acute myocardial infarction.

The use of radionuclide transit (RT) as a screening test for chest pain of oesophageal origin has been debated. The aim of this study was to determine the value of RT as a screening test for oesophageal disorders in comparison with oesophageal manometry in patients admitted with acute chest pain but without acute myocardial infarction (non-AMI patients), and to assess the frequency of oesophageal disease present in these patients. A total of 222 non-AMI patients entered the study. An extensive examination programme comprised noninvasive cardiac studies, pulmonary studies, a careful physical examination of the musculoskeletal system, and oesophago-gastric examinations including endoscopy, pH monitoring of the oesophagus and a Bernstein test. In 91% of the patients one or more diagnoses were obtained. Based on clinical and laboratory data a 'consensus' diagnosis was made. With manometry as the reference RT had a poor sensitivity (35%) but an acceptable specificity (82%). With the consensus diagnosis as the gold standard the sensitivities of both manometry and RT were poor (29%), whereas the specificity of RT, but not of manometry, was very high (97%). Gastrointestinal diagnoses were found in 57% of the patients. In conclusion, none of the applied oesophageal examinations are valuable as single screening tests. Both RT and manometry have low sensitivities. RT may be used as a cheap, noninvasive and rapid supplementary examination. When positive, it strongly supports further invasive studies of the oesophagus in non-AMI patients with unexplained chest pain.

Reproducibility of antroduodenal motility during prolonged ambulatory recording.

Ambulatory recording of antroduodenal manometry is a novel technique with several advantages over standard stationary manometry recording. Although the feasibility of this technique in clinical practice has been demonstrated, reproducibility of antroduodenal motility recorded by means of ambulatory manometry has not been investigated. To test whether antroduodenal motility recorded by ambulatory manometry is reproducible, we performed two 24-h ambulatory antroduodenal manometry recordings in 18 healthy subjects according to an identical protocol with a 1-week interval. Motility was recorded with a five-channel solid-state catheter. Postprandial motility was recorded after consumption of two test meals and interdigestive motility was recorded nocturnally. Postprandial antroduodenal motor characteristics were identical between the separate recordings. The number and duration of nocturnal cycles of the interdigestive migrating motor complex were also in the same range. Phase III characteristics in general were not different between the two recordings. Only minor alterations were observed in the duration of phase III motor fronts with duodenal onset and in the number of interdigestive cycles concluded by duodenal onset phase III. Parameters obtained by qualitative analysis were comparable between the two recordings. The antroduodenal motility pattern, when measured by ambulatory recording with solid state catheters under standardized conditions, is very reproducible.

The effect of midazolam on the normal sphincter of Oddi: a controlled study.

BACKGROUND AND STUDY AIMS: Midazolam HCl (Versed) is often used for intravenous conscious sedation in endoscopic retrograde cholangiopancreatography (ERCP) and is increasingly used in endoscopic sphincter of Oddi (SO) manometry. The effect of medications on SO motility should be fully characterized if they are to be used during SO manometry. There has been controversy as to whether midazolam influences SO motility. The aim of this study was to determine the effect of midazolam on the normal SO. PATIENTS AND METHODS: The study population consisted of 60 patients presenting with recurrent abdominal pain who were found to have SO basal pressure of less than 40 mmHg on SO manometry. ERCP was performed in the standard fashion using a pneumohydraulic capillary perfused triple-lumen catheter system in a stationary pull-through method from the pancreatic and common bile ducts. In the test group 30 patients received 2 mg midazolam intravenously while the 30 patients in the control group received intravenous saline. SO manometry was performed, with recording of the basal pressure, phasic pressure, phasic amplitude, phasic frequency and ductal pressure before and 3 min after the intravenous infusion. The changes in basal, phasic and duct pressure as well as phasic frequency before and after the administration of saline and midazolam were compared. RESULTS: Midazolam causes a small but statistically significant reduction in basal and peak SO pressure (4 and 19 mmHg respectively), compared with saline. Diagnostic concordance (normal vs. abnormal) between the basal sphincter pressure before and after midazolam was seen in 100 % of patients. Midazolam does not significantly affect phasic amplitude, phasic frequency or duct pressure. CONCLUSIONS: Midazolam does not have a clinically significant influence on the accuracy of SO manometry in identifying normal sphincteric motility.

Frequencies and cyclical pattern of the human sphincter of Oddi phasic activity.

Basal frequency of sphincter of Oddi phasic contractility has been repeatedly measured during endoscopic manometry and reported to range, in control subjects, from (M +/- SE) 3.0 +/- 0.6 to 7.5 +/- 0.7 c/min. Recently, high frequency (greater than 8 c/min) phasic contractions or absence of phasic activity were recorded in patients with postcholecystectomy or pancreatic complaints, possibly suggesting a sphincter of Oddi dysfunction. In the present study, sphincter of Oddi (biliary tract) phasic contractility was measured by perendoscopic manometry in 13 subjects without specific clinical symptoms of biliopancreatic disease and with a normal common bile and pancreatic duct at ERCP. Four T-tube patients with no evidence of common bile duct stones or papillary stenosis were studied for comparison (transductal sphincter of Oddi manometry). Basal frequency was found to range from 0 to 7 c/min (M +/- SE: 2.99 +/- 0.46) in perendoscopic manometry (85 min of recording time) and from 0 to 12 c/min (2.0 +/- 0.3) in transductal manometry (2546 min of recording time). Long lasting transductal recordings also showed that frequency of activity derived from the sphincter area varied cyclically in close relation with the duodenal migrating motor complex. It is concluded that the sphincter of Oddi in man is likely to participate in the interdigestive gastrointestinal motor activity and that short perendoscopic recordings may not be representative of the overall sphincter of Oddi activity.

Clinical value of radionuclide oesophageal transit measurement.

We have reviewed our experience of 150 patients to assess the clinical value of radionuclide oesophageal transit measurements in relation to established oesophageal motility investigations. Achalasia and conditions characterised by incoordinate oesophageal motor activity were detected with equal frequency by manometry and radionuclide transit measurement. Radionuclide transit measurements identified abnormalities not detected by manometry in 18 patients, and manometry was abnormal in 26 patients with normal radionuclide studies, including all patients with nutcracker oesophagus and most with hypertensive lower oesophageal sphincter. The overall sensitivity of radionuclide transit measurements in detecting oesophageal dysmotility was 75%, the sensitivity of manometry was 83% and that of conventional barium radiology 30%. We conclude that radionuclide transit measurement is a useful test for patients with suspected oesophageal motility disorders. Although it has limitations as a screening test, it provides additional information which complements oesophageal manometry.

Prolonged manometric recordings of oesophagus and lower oesophageal sphincter in achalasia patients.

BACKGROUND AND AIMS: Conventional short term manometry is a valuable tool in the diagnosis of achalasia but the technique may fail to detect intermittent motor events. The aim of this study was to investigate the pattern of lower oesophageal sphincter (LOS) and oesophageal pressures during prolonged recording in patients with achalasia. METHODS: Eleven patients with idiopathic achalasia were studied. Prolonged combined oesophageal pH and manometric recordings of the pharynx, LOS, and stomach were performed using a pH glass electrode and a multiple lumen assembly incorporating a Dent sleeve connected to a portable water perfused manometric system. RESULTS: LOS pressure varied during the day. Postprandial LOS pressures were lower than those recorded preprandially (1.2 v 1.8 kPa; p=0.005) and basal LOS pressures were significantly higher during phase III of the migrating motor complex than during the subsequent phase I (3.3 v 1.8 kPa; p=0.028). Complete LOS relaxations were occasionally observed in seven patients (0.48/h). Complete LOS relaxations were longer in duration than incomplete LOS relaxations (10.8 v 2.8 s; p=0.01) and 57% of complete relaxations fulfilled the criteria of a transient LOS relaxation (TLOSR). Complete LOS relaxations were associated with oesophageal pressure waves with higher amplitudes and longer durations. In addition, a higher proportion of these oesophageal pressure waves were spontaneous (55.6% v 0%; p<0.02) and multipeaked (72.7% v 0%). During prolonged manometry, high amplitude oesophageal pressure waves (>10 kPa) were recorded in six patients and retrograde oesophageal pressure waves in four, phenomena which were not observed during short term manometry. CONCLUSION: In contrast with short term stationary manometry, prolonged manometry in achalasia patients revealed the occurrence of complete LOS relaxations, TLOSRs, variations in LOS pressure associated with a meal or phase III, and high amplitude and retrograde oesophageal pressure waves.

[Evaluation of esophageal motility disorders triggered by ingestion of solids in the case of non-obstructive dysphagia].

UNLABELLED: The aim of this study was to define the normal manometric pattern of esophageal motility in response to food ingestion and to evaluate the contribution of esophageal manometry in the management of patients complaining of functional dysphagia. PATIENTS AND METHODS: Twenty-one healthy volunteers and 25 consecutive patients complaining of functional dysphagia with normal conventional esophageal manometry were included in this prospective study. An event marker was used to study the relationship between dysphagia and motility events. RESULTS: Twenty-two out of 25 patients (88%) reported dysphagia during esophageal manometry with food ingestion, while none complained of dysphagia during conventional esophageal manometry. Significantly, food ingestion induced in healthy volunteers and in patients: an increase in the amplitude and duration of esophageal body peristaltic contractions, and a decrease in their propagation speed; an increase in the basal pressure and a decrease in the relaxation percentage of the lower esophageal sphincter during deglutition. The percentage of solid swallows with one or several of the 7 abnormal motility patterns studied prospectively was significantly higher among patients (53.7%) than among healthy volunteers (4.3%) (P < 0.0001); it was also significantly higher among patients during swallows with dysphagia (70.1%) than without dysphagia (33.6%) (P < 0.0001). CONCLUSION: Esophageal manometry with food ingestion is an effective means of defining abnormal motility patterns and their relationship with dysphagia during functional dysphagia.

[Ineffective motility in lower third of esophagus. Length of involved esophagus and severity of gastroesophageal reflux disease].

UNLABELLED: Ineffective esophageal motility (IEM) has been described in patients with gastroesophageal reflux disease (GERD). Exact prevalence of IEM is unknown; however, it is associated with more severe forms of GERD. There are no studies of IEM in patients with non-erosive GERD (NERD). Traditionally, IEM is identified by manometry at 3 and 8 cm above lower esophageal sphincter. Studies evaluating each cm of distal third of esophagus to detect IEM have not been carried out to date. AIM: To determine frequency of an IEM in NERD and erosive GERD as well as in mild and severe esophagitis, and to compare traditional criteria of IEM vs. manometry of each cm of distal third of esophagus. MATERIAL AND METHODS: Healthy controls and patients with NERD and mild and severe esophagitis were studied. Manometry of each cm of lower third of esophagus was performed. Amplitude of esophageal contractions and frequency of IEM were compared between different groups of subjects and patients. The ability to detect IEM by traditional criteria and proposed criteria was determined. RESULTS: Forty-four subjects were included, 13 controls, 10 patients with NERD, 12 with mild esophagitis, and nine with severe esophagitis. Amplitude of contractions was significantly different between groups. Controls showed higher amplitude than patients with severe esophagitis. Frequency of IEM was 0% in controls, 20% in NERD, 17% in mild esophagitis, and 33% in severe esophagitis. Frequency of IEM was similar when traditional criteria and proposed criteria were compared. CONCLUSIONS: IEM occurs in NERD as well as in mild and severe esophagitis, and IEM is associated with GERD severity. Traditional manometry detects similar proportion of patients with IEM as well as manometry of each cm of lower third of esophagus.

[Peroperative diagnostic methods during esophageal achalasia surgery. Initial experience].

AIM OF THE STUDY: The authors present their first experience with the application of esophageal manometry during the operation on achalasia of esophagus. The completeness of performed myotomy is evaluated on the basis of decreased pressure in the region of lower esophageal sphincter (LES). METHODS: Stationary pull-through four-channel manometry was performed twice during the operation: before the application of capnoperitoneum to localize LES with evaluation of its length and tonus and after the myotomy was performed after capnoperitoneum was abolished to verify sufficient extent of myotomy. The subsequent endoscopic control was used to exclude damage of esophagus mucous membrane. RESULTS: In the period of one year during 2002/2003 the authors operated on four patients with achalasia, when manometry was used for peroperative localization of LES and evaluation of the extent of myotomy. The peroperation manometry demonstrated decreased tonus of LES (the mean 42.06 mmHg before myotomia and the mean 20.03 mmHg after myotomia) and in one case the finding resulted in necessary extension of myotomia. CONCLUSIONS: Based on our preliminary experience with peroperation manometry in operations on achalasia of esophagus it may be stated that it is a useful method for objectivization of the completeness of myotomy, which does not significantly prolong the period of operation. It contrast, it makes it possible to respond to lasting hypertonic area in LES subjected to myotomy, which may be the cause of lasting complaints of patients after the operation.

[Clinical significance of hiatal hernia].

A careful clinical investigation of 245 patients with hiatus hernia was performed. (History and physical examination, x-ray tests, oesophago-gastroscopy with biopsies, 3-point-manometry, rapid pull-through manometry with pentagastrintest). Classification of hiatus hernia was performed by x-ray test. (222 axial hiatus hernia, 14 mixed hiatus hernia, 9 paraoesophageal hiatus hernia) 3-point-manometry and rapid pull-through manometry with Pg-test were used to differentiate the function of the cardia. In spite of a strong selection in 84 out of 245 patients examined in our hospital, a sufficient cardia could be seen. 161 cases showed a gastro-oesophageal reflux which has been in accordance with a decompensated reflux disease in 97 patients. Solely in these 97 patients an operative correction of the gastro-oesophageal reflux seemed convenient. 84 patients showed a considerable variability of oesophageal disorders. In a final correlation between endoscopy, manometry and x-ray tests our opinion was confirmed that hiatus hernia must not lead inevitably to an insufficiency of the cardia. In the above investigations it could be shown that any therapeutic proceeding in the treatment of hiatus hernia first needs a careful analysis of the cardiac and oesophageal activity and second requires a careful indication for the surgical treatment of hiatus hernia.

Correlation of manometric and radiographic diagnosis in esophageal motility disorders.

BACKGROUND: Radiography and manometry are complementary investigations in the diagnosis of esophageal motility disorders. In most centers, however, manometry is not available and diagnosis is based on radiography alone. AIMS: To correlate the findings on radiography in patients with esophageal motility disorders in whom a manometric diagnosis was available. METHODS: Retrospective analysis of esophageal manometry and barium contrast studies of 138 patients, done for suspected motility disorders, over a period of two years. RESULTS: Manometry was abnormal in 111 (80.4%) cases [achalasia 87, scleroderma 6, non specific esophageal motility disorders (NEMD) 13, diffuse esophageal spasm (DES) 5]. Radiology was abnormal in 106 cases; the overall radiographic sensitivity was 73.9% (achalasia 87.4%, scleroderma 83.3%, NEMD 38.5%) and the positive predictive value was 75.5% (achalasia 95%, scleroderma 100%, NEMD 29.4%). CONCLUSION: Radiography has a high sensitivity and positive predictive value in esophageal motility disorders like achalasia and scleroderma but in DES and NEMD the two investigative modalities (radiography and manometry) do not correlate well.
