We present a case of 100% pneumothorax in a 41-yr-old man with a history of gastritis and gastroesophageal reflux scheduled for Nissen fundoplication. The patient was anaesthetized, and insufflation of the abdominal cavity with carbon dioxide was performed uneventfully. There was an increase in the peak inspiratory pressure and wheezing was noted with a decrease in the arterial oxygen saturation to 91%. An obstructive pattern was noted on the end tidal carbon dioxide monitor. The patient also had decreased breath sounds in the left lung field. The endotracheal tube was withdrawn 1.5 cm with equal breath sounds noted in both lung fields, but the wheezing persisted. At the end of the case the trocars were removed and the abdomen was deflated. The arterial oxygen saturation increased to 94% while breathing F1O2 of 1.0. A chest roentgenogram showed a 100% left pneumothorax. A left chest tube was placed with immediate improvement of the arterial oxygen saturation to 100%. We recommend monitoring of arterial oxygen saturation, peak inspiratory pressures, and excursion of the chest for early diagnosis and prompt treatment of pneumothorax during laparoscopic procedures.

Gastrointestinal and liver disorders are often observed in high performance athletes, especially those training for the increasingly popular endurance sports including the marathon and the triathlon. The disorders often start with stress before competition or training, followed by dehydration during the event. Insufficient training is an aggravating factor as are certain environmental factors including hot climate, irregular terrain and high altitude. Athletes may also consume non-steroid anti-inflammatory drugs, for example after a minor bone lesion or joint sprain, in an attempt to maintain their highest level of performance. Gastric signs include epigastric pain known to be caused by ischaemic gastritis resulting from decreased splanchnic flow and increased vasoconstriction in the gastric mucosa. Gastrooesophageal reflux results from modifications in sphincter tone and gastric emptying. Drinking hyperosmolar liquids also plays a role. Abdominal pain, diarrhoea, melena and uncommonly ischaemic colitis are the main signs of colic disorders. Mesenteric ischaemia may occur due to lowered splanchnic blood supply (by as much as 80% in some cases). Mechanical trauma is another mechanism; in marathon runners the "caecal slap syndrome" is a repeated microtrauma of the caecum against a hypertrophied muscular wall. Waterborne infectious agents may also lead to colic lesions. Exertion heat stroke is an emergency situation which can cause multiple organ damage and usually occurs after long intense exercise, often, but not always in a hot environment. Uncompensated thermogenesis and excessive loss of water by perspiration leads to central hyperthermia and ischaemic hepatic necrosis. Fatal liver failure has been observed. More or less severe symptoms of gastrointestinal or hepatic disorders are observed in 30% of high performance athletes and the incidence may reach 40% in those who have trained insufficiently. Such disorders lead to reduced performance in 10% of these athletes.

Helicobacter pylori is an important factor in the pathogenesis of chronic gastritis and gastroduodenal ulcer disease. However, the basic causal mechanisms of H pylori colonization on the gastric mucosa are still unclear. The authors evaluated the prevalence of H pylori colonization in 266 children who underwent upper gastrointestinal endoscopy during a 12-month period. The indications for endoscopy were follow-up of esophagitis related to gastroesophageal reflux (n = 17), suspicion of gastroesophageal reflux (n = 51), abdominal pain (n = 28), vomiting (n = 30), follow-up of esophageal atresia (n = 46) and duodenal atresia (n = 28), inflammatory bowel disease (n = 28), and miscellaneous (n = 38). The methods used to detect H pylori colonization were histology and the rapid urease test. H pylori colonization was demonstrated in 31 (11.6%) of the 266 patients. In two patient groups, a high prevalence of colonization was identified. In patients with an operated duodenal atresia, 36% (10 of 28) had H pylori on the gastric mucosa. The organism was demonstrated on the gastric mucosa in 47% (8 of 17) of the patients with gastroesophageal reflux-related esophagitis; five of the eight patients had neurological impairment. In the other patient groups, the prevalence of H pylori infection ranged from 2% to 14%. The present study suggests that, in children, the disturbed esophagogastroduodenal motility, which is commonly associated with gastroesophageal reflux and duodenal atresia, predisposes to H pylori infection.

Nodular duodenum, frequently described as nodular duodenitis, is endoscopically characterized by multiple erythematous nodules in the proximal duodenum and may represent a variant of duodenal inflammation. This study examines the incidence, clinical presentation, histologic correlates, natural history, and response to therapy of nodular duodenum in 83 patients who presented with epigastric pain, heartburn, early satiety, bloating, nausea, vomiting, or gastrointestinal bleeding. There was a previous history of peptic ulcer disease in 58% of patients and gastroesophageal reflux in 33%. None of the patients had associated end-stage renal disease. Endoscopically, in addition to nodular duodenum, esophagitis was found in 17% of patients and gastritis in 32%. Histology of duodenal nodules revealed chronic inflammation in 58% of patients, Brunner's gland hyperplasia in 9%, gastric heterotopia in 7%, and normal mucosa in 26% of patients. In a group of 34 patients studied prospectively, high dosage (300 mg orally bid) therapy with the H2-antagonist ranitidine for 8 wk significantly improved symptoms and endoscopic appearance (p < 0.05). In 26 patients who completely or partially failed H2-antagonist therapy, continuation of therapy with omeprazole (40 mg orally qd) for 8 wk significantly improved symptoms and endoscopic findings (p < 0.05) in 10 patients. These therapeutic approaches led to improvement in the endoscopic findings, but to no statistically significant changes in the underlying histologic appearance of the duodenum. We conclude that nodular duodenum is an endoscopically distinct entity that may respond clinically to antisecretory therapy, but remains difficult to eradicate completely.

Duodenal atresia and stenosis was observed in 103 infants and children from 1972 to 1991. There were 59 girls and 44 boys. Atresia was noted in 79 instances and stenosis in 24. Maternal hydramnios was detected in 33 cases, 46 babies were premature, and 31 had Down's syndrome. Fifty-four infants had significant associated anomalies including 35 with cardiac defects. Diagnosis was achieved by prenatal ultrasound examination in 14 cases, observation of a double-bubble sign on abdominal radiograph in 73, and contrast studies in 30 infants including 24 with stenosis. At operation annular pancreas was noted in 37 cases, malrotation in 37 cases, anterior portal vein in 4, and a second web in 3. Surgical treatment included duodenoduodenostomy in 85, duodenotomy and web excision in 8, and duodenojejunostomy in 10. Operative survival was 95%. Deaths were related to complex cardiac defects. Despite antenatal diagnosis, prompt intervention, and apparent early surgical success (95% survival), late deaths (5%) and late complications including motility disorders, megaduodenum, gastroesophageal reflux, duodenal-gastric reflux, gastritis, peptic ulcer disease, blind loop syndrome, and biliary-pancreatic conditions may be observed months to years after management during the neonatal period. Modifications in surgical technique including early tapering duodenoplasty may be useful, and close long-term follow-up is an essential component of patient care.

Thirty-three consecutive patients with idiopathic gastric acid hypersecretion (defined as a basal acid output > 10.0 meq/hr with a normal fasting serum gastrin level and negative secretin stimulation test) who were being treated for duodenal ulcer disease and other acid-peptic disorders were evaluated for the presence of Helicobacter pylori by means of a rapid urease test. Fourteen patients had duodenal ulcer and 19 had other acid-peptic disorders (gastroesophageal reflux in 14, including six with Barrett's esophagus; four with nonulcer dyspepsia; and one with erosive gastritis). Helicobacter pylori was present in 12 of the 14 ulcer patients (86%) compared to only two of the 19 nonulcer patients (11%) (P < 0.0001). The distribution of basal acid output for patients with duodenal ulcer was similar to that for nonulcer patients, and no significant difference in the mean basal acid output was found among Helicobacter pylori-positive compared to Helicobacter pylori-negative patients. Seven of the duodenal ulcer patients with a basal acid output greater than 15.0 meq/hr were Helicobacter pylori-positive, suggesting that the organism can withstand even extreme levels of gastric acidity. In conclusion, this study demonstrates that the prevalence of Helicobacter pylori infection in patients with duodenal ulcer disease associated with idiopathic gastric acid hypersecretion is not different from a majority of ulcer patients with normal acid secretory profiles and offers additional evidence that extreme levels of gastric acid are not bactericidal for the organism.

The effect of cholecystectomy on oesophageal function was examined prospectively. Of 37 patients studied, 17 (46 per cent) were still symptomatic 3-4 months after surgery. Thirteen patients (35 per cent) had abnormal oesophageal pH profiles before cholecystectomy, increasing to 27 (73 per cent) afterwards (P < 0.002). The mean (s.e.m.) DeMeester acid reflux score increased from 15.2(2.1) to 34.2(5.2) (P < 0.001) after operation. Lower oesophageal sphincter function, as measured by the sphincter function index, was significantly reduced in the patients with abnormal pH profiles after operation (P < 0.01). Mean(s.e.m.) supine gastric alkaline shift (proportion of time at pH > 4) increased from 9.2(2.0) to 17.7(3.7) per cent (P < 0.02) and the incidence of gastritis from eight patients (22 per cent) to 23 (62 per cent) (P < 0.001). These data suggest that cholecystectomy results in gastro-oesophageal reflux that appears to be related to compromised sphincter competence.

Hiccup is a forceful, involuntary inspiration commonly experienced by fetuses, children and adults. Its purpose is unknown and its pathophysiology still poorly understood. Short hiccup bouts are mostly associated with gastric distention or alcohol intake, resolve spontaneously or with simple folk remedies and do not require medical attention. In contrast, prolonged hiccup is a rare but disabling condition which can induce depression, weight loss and sleep deprivation. A wide variety of pathological conditions can cause chronic hiccup: myocardial infarction, brain tumour, renal failure, prostate cancer, abdominal surgery etc. Detailed medical history and physical examinations will often guide diagnostic investigations (abdominal ultrasound, chest or brain CT scan...). Gastric and duodenal ulcers, gastritis, oesophageal reflux and oesophagitis are commonly observed in chronic hiccup patients and upper gastrointestinal investigations (endoscopy, pH monitoring and manometry) should be included in the diagnostic evaluation systematically. Etiological treatment is not always available and chronic hiccup treatment has classically relied on metoclopramide and chlorpromazine. Recently, baclofen (LIORESAL) has emerged as a safe and often effective treatment.

Over a 2.5-year period, 82 consecutive children complaining of recurrent abdominal pain underwent upper gastrointestinal endoscopy. Gastroscopy confirmed pathology in 48 of the children (58.5%). Four of the children, who also had undergone gastroscopy, had other diagnoses (lactose malabsorption, hydronephrosis, yersiniosis), and 30 of the children (36.6%) retained the initial diagnosis of recurrent abdominal pain syndrome. Gastritis was found in 48 of the children, 18 of whom (37.5%) had positive test results for Helicobacter pylori, based on histology and/or culture. Of 16 H. pylori-positive children tested, 12 (75%) also had an elevated concentration of IgG-class antibodies to H. pylori in their sera. Three of the children had duodenal ulcer disease, all of whom were H. pylori positive. Esophagitis was found in eight of the children with gastritis, all of whom were found to have gastroesophageal reflux. Our data suggest that among the children with recurrent abdominal pain syndrome, organic pathology is more common than was previously thought. Altogether 22% of the children with recurrent abdominal pain syndrome were infected with H. pylori.

This paper identifies the symptom profile associated with the four main diagnoses of functional digestive disorders (dyspepsia, gastro-oesophageal reflux disease (GORD), gastritis, and constipation) made by general practitioners in Belgium. Results are also presented from a multicentre study in which the effects of cisapride, administered as an oral tablet or suspension, were evaluated in patients with these functional digestive disorders. Analysis of symptom patterns revealed that early satiety and postprandial abdominal bloating were the most prominent symptoms, followed by eructation (belching), heartburn, regurgitation, postprandial epigastric burning or discomfort, and nausea. These symptoms occurred in all diagnostic groups. However, different symptom patterns were associated with each of the disorders; for example, heartburn and regurgitation were the core symptoms in patients diagnosed as having GORD, early satiety and abdominal bloating were characteristic of patients diagnosed with dyspepsia, and fasting or postprandial pain were characteristic of patients given the diagnosis of gastritis. Therefore, it appears that these diagnoses used by general practitioners in Belgium closely correspond to reflux-like, dysmotility-like and ulcer-like dyspepsia, as defined by an international working party. Cisapride improved the core symptoms in about 80% of patients with GORD or dyspepsia, relieved all epigastric symptoms in about 80% of patients with gastritis, and significantly decreased the use of laxatives and increased stool frequency in constipated patients. Cisapride was well tolerated and thus appears to be a useful option in the treatment of functional digestive disorders in a general practice setting.
