Simultaneous combined pancreatic test.

A simultaneous combined pancreatic test can be performed in one morning with only one intubation of the duodenum. The test includes the measurement of exocrine pancreatic secretion of bicarbonate, enzymes, and radioactive selenium, pancreatic scanning, hypotonic duodenography, and cytology of the duodenal aspirate. In the first 70 patients it was found that a single secretion test was of only limited value in detecting pancreatic disease; cytology was the most reliable and scanning the least reliable single test; and that the combined test provided near-complete discrimination between patients with no pancreatic disease, with chronic pancreatitis, and with carcinoma of the pancreas.

[Endoscopic removal of an intraluminal duodenal diverticulum in an adult with upper abdominal pain].

We report here on a 44-year-old previously healthy patient with a two-year history of intermittent upper abdominal pain. In the outpatient gastroduodenoscopy and X- ray examinations of the small intestine an intraluminal duodenal diverticulum was suspected. Clinical examination and laboratory tests did not show any abnormal findings. In order to exclude other causes for the patient's complaints coloscopy, ERP and MRCP were performed. The latter was done because the bile duct could not be intubated in the ERCP due to the altered anatomy. By use of endoscopic ultrasound a mucosal duplication was demonstrated and thus the diagnosis confirmed. Subsequently, the diverticulum sac was sliced by argon plasma coagulation. The postinterventional course was without complications and the patient was without symptoms afterwards. The intraluminal duodenal diverticulum is a rare differential diagnosis of pain in the upper abdomen. The diverticulum should be endoscopically removed if other causes for abdominal pain have been ruled out and possibly associated malformations have been excluded.

[Pancreatic response to graded doses of synthetic secretion: comparison between intravenous and pernasal administration in man].

The response of the human pancreas to varying doses of pure synthetic secretin administered intravenously and, for comparison, 8 days later in the form of snuff was examined, intraindividually, in 10 healthy test subjects. After intubation of the stomach and duodenum and continuous instillation of radioactive vitamin B12, the recovery rate of the marker substance was measured in duodenal aspirates and employed to compute the pancreatic bicarbonate and enzyme outputs. The dose-response relationship between pancreatic bicarbonate production and varying doses of synthetic secretin administered intravenously and in the form of snuff, was good. The pancreatic response to a dose of secretin snuff was only about 1/25 of the response obtained with the same dose of secretin injected intravenously. The level of the pancreatic enzyme output remained relatively uninfluenced by varying doses of synthetic secretin.

[A nontraditional approach to the study of gastric contents].

Acidification of the gastric contents is known to be the principal function of the stomach. The efficacy of acidification for digestion is limited by chymus formation, and that for absorption manifests as the enteral barrier permeability governing, mediated by the duodenal hormonal system, thus optimizing the absorption of nutrient substances in accordance with homeostasis requirements. The author suggests a simplified method of gastric intubation, improving the informative value of the results of examination.

Effect of cigarette smoking on competence of the pylorus: preliminary study.

The competence of the pylorus was studied in 13 normal volunteers and nine dyspeptic patients by means of a radiological technique involving intubation of the duodenum. The pylorus was found to be competent in most normal individuals and in fewer than half of the dyspeptic patients. However, on smoking a cigarette, appreciable increase in duodenogastric reflux was seen in nine out of the 13 normal volunteers and in seven out of the nine dyspeptic patients. Such induced pyloric incompetence and the resultant regurgitation of duodenal juices may explain the increased incidence of gastritis and gastric ulceration in heavy smokers.

Diagnosis and treatment of jejunoileal atresia.

A total of 116 cases of intestinal atresia or stenosis were encountered at the Yale-New Haven Hospital between 1970 and 1990. Sites involved were the duodenum (n = 61; 53%), jejunum or ileum (n = 47; 46%), and colon (n = 8; 7%). All but two patients underwent operative correction, for an overall survival rate of 92%. Challenging problems were the management of apple-peel atresia (five patients), multiple intestinal atresia with short-gut syndrome (eight patients), and proximal jejunal atresia with megaduodenum requiring imbrication duodenoplasty (four patients). Major assets in the improved outlook for intestinal atresia are prenatal diagnosis, regionalization of neonatal care, improved recognition of associated conditions, innovative surgical methods, and uncomplicated long-term total parenteral nutrition.

Nonoperative management and delayed hemorrhage after pediatric liver injury: new issues to consider.

The authors report the case of a grade 4 liver laceration caused by blunt abdominal trauma. The liver injury was managed nonoperatively, both initially and after an episode of delayed hemorrhage. The patient suffered 2 additional as yet unreported complications of pediatric liver injury: a right pleural effusion causing respiratory embarrassment followed by duodenal obstruction; the latter was caused by hypertrophy of the left lobe of the liver. Although numerous reports suggest that delayed hemorrhage after pediatric liver injury should be managed operatively, the mortality of such intervention remains high, reaffirming the dictum that one must treat the patient and not the injury.

Duodenal atresia: a comparison of three modes of treatment.

To determine the most successful mode of treatment, 33 consecutive cases of duodenal atresia treated by duodenoduodenostomy and not associated with other gastro-intestinal anomalies were analysed retrospectively. These patients have been placed in a nonrandomised fashion into one of three groups: Group A: Duodenostomy (side to side) with gastrostomy and transanastomotic feeding tube (n = 12); Group B: Duodenoduodenostomy (diamond shape) with jejunostomy feeding tube (n = 12); Group C: Duodenoduodenostomy (diamond shape) only (n = 9). A nasogastric tube was used in all cases. There was no difference between the groups for gestational age, birthweight, and age at operation. The outcome measures used to compare these groups were the time taken to achieve full preanastomotic feeds and the duration of hospital stay. There was no difference in time taken to achieve full pre-anastomotic feeds between Group A and Group B. Patients in Group C took significantly less time to achieve full pre-anastomotic feeds than either of the other two groups (p < 0.05, Mann-Whitney U). The duration of hospital stay was also significantly shorter for patients in Group C (median = 12 days) than for patients in either Group A or B (median = 24, 20 days respectively) (p < 0.05, Mann-Whitney U).

Respiratory and nonrespiratory effects of doxapram in congenital central hypoventilation syndrome.

Doxapram is a respiratory stimulating drug that affects both peripheral chemoreceptors and medullary respiratory and nonrespiratory neurons. We administered doxapram 60 2 infants with congenital central hypoventilation syndrome. In 6 separate trials at a dose range of 0.32 to 2.0 mg per kg of body weight per min, quiet-sleep tidal volume increased from 4.9 +/- 1.0 to 8.5 +/- 0.9 ml per kg of body weight, minute ventilation increased from 140 +/- 38 to 286 +/- 31 ml per kg of body weight per min, and alveolar PCO2 decreased from 60 +/- 5 to 32 +/- 2 mm Hg. In all instances, the maximal quiet-sleep ventilatory response was achieved within 10 min. The ventilatory response to steady-state CO2 breathing was not improved with doxapram. A continuous infusion of doxapram for 5.2 days in one infant successfully maintained normal quiet-sleep ventilation. In both infants, multiple nonrespiratory effects of doxapram occurred; enteral administration was associated only with generalized neuromuscular stimulation, but the 5-day intravenous infusion was also associated with acute hepatotoxicity and a perforated duodenal ulcer. The medullary respiratory neurons in central hypoventilation syndrome may be incapable of responding to doxapram, and the ventilatory responses observed may be due entirely to stimulation of peripheral chemoreceptors. Although quiet-sleep ventilation can be successfully maintained with intravenous and enteral administration of doxapram, and tachyphylaxis has not been observed, we have been unable to avoid at least the neuromuscular manifestations of nonrespiratory medullary stimulation.

Intestinal perforations secondary to nasojejunal feeding tubes.

Infant alimentation by nasojejunal tube feeding has been successfully used since 1973. A significant complication is small bowel perforation by the tube; three cases are presented. The differential diagnosis includes spontaneous gastric perforation and necrotizing enterocolitis. Nasojejunal tube perforation almost always occurs in the distal duodenum. It is likely the result of peristaltic activity which propels the tube along the relatively rigid duodenal loop. Thus it is preferable to position the tube end distal to the ligament of Treitz.

[Prolonged respiratory depression following general anesthesia in a patient with dystrophia myotonica].

A case of general anesthesia for a 52 year old female with previously undiagnosed dystrophia myotonica was reported. The patient was diagnosed as flaccid paralysis of the bilateral lower extremities but myotonic symptoms were not found preoperatively. The patient underwent duodenal resection to have a benign tumor removed. Anesthesia was induced with thiamylal 250 mg and pancuronium bromide 4 mg intravenously to facilitate tracheal intubation. Anesthesia was maintained with enflurane (0.6-1.0%) in nitrous oxide (50%) and oxygen (50%). The course of anesthesia was uneventful except for a transient hypotension of 80 mmHg systolic for about 10 minutes. The patient did not recover smoothly from anesthesia and prolonged apnea was observed. 90 minutes after the end of surgical procedure, spontaneous ventilation appeared. Then the tidal volume increased gradually but it still remained around 100-150 ml even 3 hours after the end of the operation. She was on ventilator and observed carefully. The endotracheal tube was removed four days after the operation. The patient was examined again by a neurologist and a final diagnosis of dystrophia myotonica was made. Prolonged recovery from anesthesia and postoperative respiratory depression observed in this patient was due to preoperatively undiagnosed dystrophia myotonica. A careful preoperative examination should be made to minimize possible complication related to anesthesia in the disease.
