Acute toxicosis developed in a group (n = 35) of fattening hogs and replacement gilts that had excessive vitamin D3 inadvertently added to their feed. All of the pigs were lethargic, and emesis was evident in about half of the pigs 1 to 2 days after they consumed the feed. On the 2nd day, 3 of the pigs died. The remaining pigs were given a different ration. Five additional pigs died during the next 2 weeks. Clinical toxicosis also was observed in 1 of 2 feeder pigs fed the suspect feed in the laboratory and in 2 of 2 pigs fed the suspect feed by the company that had mixed the feed. Gross necropsy findings consistently observed were hemorrhagic gastritis and diffuse interstitial pneumonia. Myocardial degeneration and nephrosis were seen in, respectively, 1 of 6 and 4 of 6 pigs necropsied. Histologically, necrosis and mineralization of variable severity were observed in the fundic gastric mucosa, lungs, kidneys, bone, heart, and small blood vessels of the lungs and heart. Less necrosis and more mineralization were observed in pigs that survived longer than 6 days. The 2 pigs fed the suspect feed in the laboratory had increased concentrations of serum calcium from the 3rd to the 9th days or the 1st to the 3rd days, after feeding the suspect feed. Serum phosphorus concentrations were increased from the 1st until the 2nd or 3rd day, and serum magnesium concentrations were increased from the 1st or 2nd to the 3rd day after feeding the suspect feed.(ABSTRACT TRUNCATED AT 250 WORDS)

Alkaline reflux (bile) gastritis and esophagitis result from mucosal injury by duodenal contents. Bile gastritis occurs after gastric surgery, cholecystectomy, ampullary sphincteroplasty, and, rarely, in nonoperated patients. Diagnostic features include chronic, continuous epigastric pain, exacerbated by eating, bilious vomiting, weight loss, iron deficiency anemia, achlorhydria, gastritis, and intragastric bile. The pathophysiology probably relates to excess enterogastric reflux and bile-induced mucosal damage. There is no perfect diagnostic test, but chemical and scintigraphic documentation of enterogastric reflux, as well as provocative testing with alkali solutions, are promising new techniques. Medical therapy with antacids, H2 antagonists, bile salt absorbants, and metoclopramide has been without significant benefit. Prostaglandins and sucralfate are now being evaluated. Surgical therapy that diverts duodenal contents away from the stomach is usually of benefit in appropriately selected patients. Alkaline reflux esophagitis shares many features with alkaline gastritis.

71 patients participated in a double-blind trial which compared proximal gastric vagotomy (PVG) with vagotomy and antrectomy (V & A). 82 percent of the patients subsequently volunteered for endoscopy 6 to 12 months after operation and 65 percent for measurement of fasting bile reflux (FBR) and peak acid output (PAO). The results of these follow-up assessments are given in this paper. None of the 36 patients who had undergone V & A had a recurrent ulcer; in contrast ulcers or fresh scars were found in 5 of 35 patients after PGV, even in 2 who had no symptoms. Erythema of the gastric mucosa was seen more commonly after V & A than PGV. Such erythema was associated with high levels of fasting bile reflux (an objective measure of reflux of bile into the stomach) and with symptoms of bile vomiting and mild epigastric pain. High levels of fasting bile reflux were not found after PGV. Histological gastritis of the proximal stomach was equally common after both operations in patients without a recurrent ulcer. Gastritis was not related to endoscopic mucosal erythema or fasting bile reflux, but did correlate with peak acid output. These results confirm that bile reflux is associated with mucosal erythema and symptoms after V & A but that significant bile reflux does not occur after PGV. However, bile reflux is not related to gastritis, which appears to be the result of an operation (either PGV or V & A) which successfully reduces peak acid output.

At the University of Minnesota under the supervision of one staff surgeon both jejunoileal bypass (JIB) and gastric bypass (GIB) operations have been performed for weight reduction in morbidly obese individuals. During the last 14 years 727 patients underwent end-to-end (40 to 4 cm) JIB and more than 570 patients underwent GIB. This report is based on a comparison of 205 JIBs performed between July 1975 and July 1979, 106 Alden-loop type GIBs (GIB-loop) performed between July 1975 and July 1979, 53 loop GIBs with enteroenterostomies between the limbs of the loop (GIB-EE) performed between May 1980 and May 1981, and 57 Roux-en-Y GIBs (GIB-Roux) performed between May 1981 and May 1982. Adequate weight loss occurred in 80% of the patients who returned for follow-up in all groups. The percentage of excess body weight loss was similar for the first year (65% for JIB, 62% for GIB-loop, 69% for GIB-EE, and 71% for GIB-Roux). The operative mortality and the immediate morbidity rates were uniformly low. The long-term complications for JIB were 37.7% arthralgia, 7.1% oxalate urolithiasis, 5.6% incisional hernia, and 1.4% liver failure. The complications for GIB-loop were 10.2% nausea/vomiting, 1.9% bile reflux gastritis, and 2.8% anastomotic problems; for GIB-EE 23% nausea/vomiting, 7% bile gastritis, 4.6% incisional hernia, and 3.7% anastomotic problems; and for GIB-Roux 16% nausea/vomiting and 1.7% anastomotic problems. The anastomotic problems consisted of afferent loop obstructions and stomal stenosis; there were no leaks. At 1 year plasma cholesterol reduction for JIB averaged 42% (p less than 0.001), GIB-loop 14% (p less than 0.001), GIB-EE 7% (NS), and GIB-Roux 17% (p less than 0.001). One year after operation 49% of 88 JIB patients showed progression of liver disease on sequential biopsy specimens and 20% improvement. In the 78 GIB patients with sequential biopsies, liver disease progressed in 8% and improved in 65%. In summary, comparable therapeutic weight reduction occurred with all the assessed procedures; however, the GIB-Roux was associated with far fewer serious long-term complications. At this time the GIB-Roux procedure is the weight reduction operation we recommend.

The authors describe a case of gastric tuberculosis in a 23 years old African patient from Abidjan. Symptomatology included epigastralgia, post prandial vomiting, severe impoverishment of health state and dehydration. Endoscopy showed a pseudopolypoid diffuse gastritis with an infiltrated like mucosa. Endoscopic biopsy was carried out, but, because of clinical aggravation (epigastric muscular defense), the patient underwent a laparotomy before knowing the results of the biopsy. Gastrotomy showed an hypertrophied granulomatous hemorrhagic mucosa. By histological examination it was concluded in favour of a granulomatous gastritis with pan-parietal tuberculoid lesions without acid-alcohol-fast bacilli. The different causes of granulomatous gastritis were reviewed and a tuberculous etiology suspected. An antituberculous therapy was prescribed with excellent results on clinical and endoscopic standpoint one year after the treatment started.

Sixteen gastrectomized patients underwent surgical treatment for alkaline reflux gastritis by means of a Roux-en-Y loop duodenal diversion. Long-term evaluation of results was performed 5-9 years later. Ten patients (62.5%) showed good results, with absence of digestive symptoms and with an increase in body weight. Two patients (12.5%) had moderate results, with presence of sporadic and mild epigastric pain. Four patients (25%) had unsatisfactory results, with persistence of epigastric pain and absence of body weight increase. No patient had recurrent biliary vomiting or endoscopic evidence of endogastric biliary reflux. Among the six patients with moderate and unsatisfactory results, two had a significant alcoholic intake, two showed a high degree of anxiety on psychological assessment, and two had both factors. Alcoholism and psychological disturbances should be considered exclusion criteria when evaluating a gastrectomized patient for surgical cure of alkaline reflux gastritis.

Alkaline reflux gastritis following gastric surgery is an ill-defined syndrome characterised by epigastric pain, bile vomiting and weight loss. Endoscopy and gastric histology do not confirm the diagnosis. It appears that duodenal contents refluxing into the stomach are the cause of this entity. In an effort to quantify this attempts have been made to quantitate the reflux. Techniques include measuring bile acids in fasting gastric aspirates and, more recently, Tc HIDA scanning. Tolin et al showed a good correlation between the enterogastric reflux index and patients with symptoms of alkaline reflux gastritis. Recent work has suggested that HIDA reflux is difficult to quantitate. Recently Meshkinpour et al induced the symptoms of alkaline reflux gastritis by infusing endogenous duodenal juice onto the gastric mucosa. This paper confirms those findings and uses the technique to improve patient selection for Roux-en-Y diversion.

Forty endoscopic examinations of the upper gastrointestinal tract were performed in 38 infants with an age range from 2 days to 12 months. The main indications were upper gastrointestinal bleeding, chronic intractable vomiting, and small intestinal biopsy. Duodenal ulcer, hemorrhagic gastritis, and gastric erosions were the most common causes of upper gastrointestinal bleeding in infancy. An acute viral infection with fever, aspirin ingestion, and diarrhea frequently preceded gastrointestinal bleeding from duodenal ulcer and gastric erosion. Four of the 27 bleeding patients demonstrated no abnormality endoscopically.

Nausea in pregnancy is very common but it is astonishing that so little data are available concerning the cause and course of this disorder. A questionnaire was mailed to all women who had given birth to at least 3 children, the last delivered in 1980 or 1981 in our department. 244 (75%) responded, mean age 33 years, range 23-45. A total of 948 pregnancies resulted in 855 children, 56 spontaneous and 25 legal abortions, 8 twins and 4 ectopics. 70% of all pregnancies were associated with nausea and 52% of the patients always experienced nausea during their pregnancies, while 17% never and 31% only occasionally felt sick. For 91% of the cases, the onset of nausea was during the first 3 months. There was no difference concerning intensity, 'peak nausea' or onset, whereas duration decreased with subsequent pregnancies. 7 of 8 women with twin pregnancies complained of nausea, contrasting to 50% with spontaneous and 80% with legal abortions. Age, smoking or 'pregnancy complications' did not correlate with nausea. There were, however, correlations (p less than 0.05) between nausea and gallbladder disease, gastritis and allergy. All patients with gallbladder disease had nausea and so had 90% of those with allergy and gastritis. There was also a strong correlation (p less than 0.001) between nausea in pregnancy and 'intolerance' of oral contraceptives, as 98% of these women experienced nausea. The data obtained do not support a correlation between HCG and emesis gravidarum, but rather suggest an association with steroidal hormones and liver function.

Nineteen patients with a history of heartburn, bile vomiting, and postprandial pain after gastric surgery have been compared with 16 symptom-free gastrectomized patients with regard to bile reflux, gastric emptying rate, and gastric mucosal changes. Bile reflux was determined by an isotope-derivative method. Gastric emptying of a liquid meal was studied by a dye dilution technique. Gastric mucosal morphology was studied in biopsies taken at gastroscopy. A significantly higher degree of bile reflux could be demonstrated in patients with symptoms than in symptom-free patients. Gastric emptying of a liquid meal occurred at the same rate in both groups. There was no correlation between the gastric emptying rate and the amount of bile reflux. The gastritis was of the same severity in patients with and without symptoms and was not related to the degree of bile reflux.
