Two-dimensional echocardiographic features of right ventricular infarction.

Real-time, two-dimensional echocardiographic studies were performed in 10 patients with acute myocardial infarction who had clinical features suggestive of right ventricular involvement. All patients showed right ventricular wall motion abnormalities. In the four-chamber view, seven patients showed akinesis of the entire right ventricular diaphragmatic wall and three showed akinesis of segments of the diaphragmatic wall. Segmental dyskinetic areas involving the right ventricular free wall were identified in four patients. One patient showed a large right ventricular apical aneurysm. Other echocardiographic features included enlargement of the right ventricle in eight cases, paradoxical ventricular septal motion in seven cases, tricuspid incompetence in eight cases, dilatation of the stomach in four cases and localized pericardial effusion in two cases. Right ventricular infarction was confirmed by radionuclide in seven patients, at surgery in one patient and at autopsy in two patients.

Course of apoptotic changes in the rat gastric mucosa caused by oral administration of fusarenon-X.

Male 5-week-old Wistar rats orally (po) administered with fusarenon-X (FX) 1.5 mg/kg and control rats po-treated with distilled water were sacrificed at 0-48 hr after gavage. FX-administered rats showed significant dilatation of the stomach with increased fluid contents at 1-24 hr postadministration (PA). Histopathologically, karyopyknosis of chief cells in the basal region of the gastric glands began to appear at 1 hr, and nuclear fragments were seen in the neck cell region at 1.5 hr PA. At 2-4 hr PA, apoptotic cells appeared diffusely in the neck region and focally in the basal region. Electron microscopy revealed that cells phagocytosing apoptotic bodies were the surface epithelia, undifferentiated neck cells, parietal cells and chief cells. No evidence was detected to show that parietal cells underwent apoptotic changes. The apoptotic lesions peaked at 4-6 hr PA, gradually subsided at 12 hr PA, and became minimal leaving apoptotic remnants in the basal region at 24 hr PA. At 48 hr PA, however, diffuse apoptotic lesions reappeared in the basal region at a level similar to that at 2-3 hr PA. This might be attributable to absorption of FX retaining in the stomach for 24 hr. In situ detection of DNA breaks by the terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) reaction was consistent with the histopathologic findings. Agarose gel electrophoresis of DNA fragments isolated from the gastric mucosae of FX-administered rats showed a ladder pattern after 1.5 hr PA and the pattern became more distinct at 2-4 hr PA.

Laparotomic vs laparoscopic lap-band: 4-year results with early and intermediate complications.

BACKGROUND: Adjustable banding is safe, low invasive, and effective for losing weight. METHODS: 69 patients underwent this procedure by laparotomy or laparoscopy. RESULTS: Patients operated by laparotomy lost more weight than those operated by laparoscopy, but in 4 patients we were forced to re-operate in order to remove the band (3 pouch dilatations and 1 stomach slippage), and in 9 patients a ventral hernia appeared (5 patients repaired). In the laparoscopic cases there were 4 intra-operative gastric perforations, but all were repaired and the band placed at the same time (3 conversions to open), causing an increased post-operative hospital stay. There was a lower limb deep venous thromboembolism, which was followed by fatal pulmonary embolism (although the patient had been given heparin and had been treated with elastocompression and mobilization 2 hours after surgery). The band eroded in one patient. Weight losses in these morbidly obese patients were satisfactory at 2 years and maintained beyond 3 years. CONCLUSION: Laparoscopic adjustable banding is an efficient, generally safe procedure.

Biliopancreatic diversion for treatment of morbid obesity: experience in 50 cases.

BACKGROUND: Biliopancreatic diversion (BPD) by Scopinaro's method is an operation advocated by some surgeons as an effective treatment for morbid obesity. METHODS: Between February 1995 and April 1997 we performed BPD by Scopinaro's method on 50 patients with morbid obesity (23 males), average age 41.4 years (range 20-63 years), average body weight 135.08 kg (range 89-256 kg), mean body mass index (BMI) 50.65 kg/m2 (range 37.01-81.56 kg/m2). RESULTS: In all cases a gradual decrease in weight was obtained [mean BMI at 1 month: 44.8 kg/m2, at 6 months (31 patients): 35.09 kg/m2, at 1 year (23 patients): 31.36 kg/m2, at 18 months (14 patients): 29.89 kg/m2 and at 2 years (5 patients): 29.27 kg/m2]. At the same time a significant improvement in the pathological conditions associated with morbid obesity was observed. The patients were able to suspend oral antihypertensive and antidiabetic therapy as these parameters spontaneously returned to normal values by the sixth postoperative month; all cases showed a marked reduction in hypercholesterolemia and hypertriglyceridemia. Postoperative complications were: one death (2%) on the third day due to heart failure; two late intestinal occlusions (4%); one acute dilatation of the stomach (2%); one peritonitis caused by early dehiscence of the anastomosis (2%); five anastomotic ulcers (10%); two cases of protein malnutrition (4%). CONCLUSIONS: BPD by Scopinaro's method is a bariatric procedure which is technically complex. However is it safe and reproducible and it induces a substantial weight loss.

[Single dose toxicity studies of calcipotriol (MC903) in rats and dogs].

A single dose toxicity of calcipotriol (MC903), an anti-psoriasic agent, administered subcutaneously (s.c.) and percutaneously (p.c.) was studied in Slc:SD rats (s.c. and p.c.) and beagle dogs (s.c.). The LD50 values of MC903 were as follows: rats, 2.19 mg/kg in males and 2.51 mg/kg in females by s.c., and more than 15 mg/kg in both sexes by p.c.; dogs, more than 1.5 mg/kg in males by p.c. No sexual difference was noted in LD50 values of rats. Death of rats was observed from 1 to 3 days after administration by both routes. Dead animals showed decreases in body weight and locomotor activity, reddish tear, abnormal gait and dirty hair by both routes. Furthermore, dead animals administered by s.c. showed salivation, nasal discharge, piloerection, ptosis, diarrhea, urorrhea, nasal and vaginal bleeding, subnormal temperature, loose stool, cyanosis, irregular and deep respirations, clonic and tonic convulsions. Survival of rats showed similar signs to those of dead animals except for nasal discharge, nasal and vaginal bleeding, cyanosis, agonal respiration and convulsion. Discoloration of the kidney, white patch of the heart and a dilatation of the stomach wall were observed on macroscopic examinations. No mortalities were observed in dogs which showed vomiting, conjunctival congestion, circumoral and auricular reddenings, periblepharal purplish reddening, decreases in locomotor activity and defecation, emaciation, eye discharge, skin desquamation of treated area and an increase in respiration. On macroscopic examination, desquamation of the skin, reddening of the circumoral mucosa, pale gray yellow striations in renal tubules of the cortex and discoloration of the thyroid were observed. Histopathological findings revealed epidermal thickening with parakeratosis, fibrocytes, hypertrophy and hypersecretion of the sebaceous and sweat glands, formation of epitheloid glanulomas and infiltration of neutrophils in the subcutaneous tissues. Furthermore, moderate calcium deposits in the renal tubules, fatty cells and slight calcium deposits in interstitial tissues of the thyroid, and a cystic nest of an ectopic intestinal epithelium between muscle layers of the duodenum were observed at the highest dose. On the basis of results obtained in the present study, rats administered MC903 by s.c. or p.c. died probably due to the circulatory and renal disturbance resulted from effects of this drug on the heart and kidney.

[Acute damage to the myocardium and left lung is a complication of high-frequency percutaneous thermoablation of solitary metastasis of renal cancer into the liver (a clinical observation)].

The paper describes a case of severe complication of radio-frequency percutaneous thermoablation of renal metastasis into the liver, which occurred in a young woman with the intact cardiovascular system and manifested itself in the development of alveolar edema of the lung and acute dilation of the stomach. Pulmonary edema resulted from left ventricular myocardial and pulmonary parenchymal lesions and acute mitral valvular insufficiency. The authors' considerations as to the possible cause and mechanisms of development of this life-threatening complication first described in the literature are also given.

A case of familial visceral myopathy with atrophy and fibrosis of the longitudinal muscle layer of the entire small bowel.

The case of a 21-yr-old man, who died in cachexia after 2 yr of intermittent abdominal pain, bouts of diarrhea, and anorexia, is reported. Laboratory tests performed shortly before death disclosed signs of malabsorption. Radiologic examination of the gastrointestinal tract showed a coarse mucosal relief in the upper jejunum and a tubular aspect in the rest of the small bowel. There was no dilatation of the loops. Autopsy revealed severe to complete atrophy with fibrosis of the outer muscle layer of the entire small bowel, extending from the pylorus to the ileocecal valve. The only other lesion discovered was a moderate portoportal fibrosis of the liver. The patient's brother had died a few months earlier after 2.5 yr of similar symptoms. An upper gastrointestinal series had shown dilatation of the stomach with fluid retention and a tubular aspect of the small bowel with generalized widening of the loops. No autopsy was performed. There was a high degree of consanguinity on the mother's side. Family history revealed no other evidence of possible genetic factors in the disease.

[Acute abdominal complications after thoracic-pulmonary operations].

Serious abdominal complications occurring after chest and lung operations are discussed. The most common abdominal complications include acute dilatation of the stomach, paralytic ileus, gastrointestinal tract hemorrhage, as well as perforations of hollow abdominal organs. An interesting case presenting perforation of the small intestine after lung resection for pulmonary carcinoma is reported. The attention of surgeons is called to severe surgical complications, such as profuse hemorrhages from the gastrointestinal tract, and perforations of hollow abdominal organs, first and foremost.

Transhiatal oesophagectomy for benign obstructive conditions of the oesophagus.

BACKGROUND: Transhiatal oesophagectomy is an accepted approach for the treatment of carcinoma of the oesophagus. However, experience of this technique in benign diseases is limited. METHODS: Transhiatal oesophagectomy was done in 29 patients for benign oesophageal conditions including corrosive stricture (21), achalasia of the cardia (four), tuberculosis (one), mediastinal fibrosis (one), Crohn's disease (one) and peptic stricture (one). Dysphagia was the predominant symptom in all patients; strictures had all previously been dilated repeatedly. The stomach was used as an oesophageal substitute in 24 patients; in five with a scarred stomach due to damage by a corrosive agent, oesophagocoloplasty was performed. Resection and reconstruction were done in one stage in 25 patients; four with poor nutritional status had a two-stage procedure. RESULTS: There was no perioperative death. Complications encountered were recurrent laryngeal nerve palsy (six patients) which was mostly transient, anastomotic leak (seven) and stenosis (eight). Postoperative function of the intrathoracic stomach was satisfactory. CONCLUSION: Transhiatal oesophagectomy is a safe and satisfactory procedure for benign obstructive conditions of the oesophagus.

[The significance of disturbances of draining functions of the azygos vein in pathogenesis of varicose dilatation of the veins of the esophagus and stomach in portal hypertension (experimental-clinical investigation)].

Under analysis were the results of investigations on 30 corpses, 25 dogs and of examinations of 187 patients with portal hypertension. In the experiments the disturbances of blood flow in the portal and azygos veins and the veins of the gastroesophageal basin were modeled. It was found that changes of the veins of the esophago-gastric area in diffuse lesions of the liver were already present even if there were no definitely detectable signs of portal hypertension. The experimental osseo-azygography has revealed dilatation of the azygos vein. The findings of examination of the patients admitted with esophago-gastric bleedings allowed detection of 5 degrees of impairments of blood flow along the azygos vein which increased risk of esophgeal-gastric bleedings.

Gastric distension, cerebral palsy and unexpected death.

Two cases of unexpected death from massive gastric dilatation in individuals with severe spastic quadraparesis aged 14 and 20 years, respectively, are reported. Spontaneous rupture of the stomach occurred in one case. Predisposing factors to gastric dilatation associated with cerebral palsy include autonomic neuropathy, neuromuscular incoordination, air swallowing and malposition of the stomach. Death may be due to compromise of respiratory function caused by lung compression by the dilated stomach, or to peritonitis with sepsis. Acute gastric dilatation, with or without rupture, should be considered a potential cause of unexpected death in individuals with severe mental and physical disabilities.

[Apico-thoracic retro-aortic anastomosis in radical operation for esophageal carcinoma].

OBJECTIVE: To evaluate the result of surgical treatment of the middle and upper-middle esophageal carcinoma with a new operation, performing the anastomosis posterior to the aortic arch at the apex of the thoracic cavity. METHODS: From April 1996 to May. 2000, 179 patients with esophageal carcinoma were treated. Sixty-eight of these patients (49 in the middle and 19 in the upper-middle segment) were treated by esophogogastrostomy at the top of the chest, posterior to the aortic arch. There were squamous cell carcinoma 50, adenocarcinoma 16, undifferentiated carcinoma 2, including 8 double-primaries. The lesions were stage I 9 and stage II-III 59. RESULTS: All patients have been alive after follow-up of 2 months to 3 years. Without any positive margins, anastomotic leak or perioperative death, this new method has merits: 1. Length of esophagus resected was maximal through one single incision. It would be especially useful for some of the upper-middle lesions. 2. This new method requires a shorter transposed stomach than that required by the combined triple cervico-thoraco-abdominal approach. 3. As the site of thoracic stomach was on the bed of esophagus, there was less chance of post-operative embarrassment in respiration due to the dilatation of the transpositioned stomach and pylorostenosis, etc. 4. There would be less chance of reflux esophagitis because of the "blocking" by the aortic arch, thereby, the patients life is improved. CONCLUSION: This radical operation for esophageal carcinoma with anastomosis at top of the thoracic cavity posterior to the aortic arch, being a newly designed surgical method, is especially useful for carcinoma in the middle and upper-middle esophageal segment.

[Operation for draining the stomach by subtotal pyloro-myectomy with and without dilatation of the mucous membrane (author's transl)].

According to our experiences a pyloroplasty adequate in shape and function can be formed by a separate plastic surgical treatment of the serosa muscularis and mucosa, which can not only be carried out in a very simple way, but if strict attention is paid to its indications and the technical details are adhered to exactly, it also guarantees a complete normalization of evacuation of the stomach without dumping syndrome and duodenal reflux with satisfactory reliability. The necessary intervention consists essentially of a subtotal pyloro-myectomy which is combined with distention of the canal mucous membrane if it is too narrow.

[Therapy and follow-up of gastroesophageal chemical burns].

We report a retrospective analysis of 61 patients admitted during the years 1974 to 1992 after having recently swallowed a corrosive agent. Within 24 hours, the localisation, severity and extent of the injury had been determined by endoscopy. In 13 patients the injury was restricted to the oropharynx, and in 48 it involved esophagus, stomach and duodenum. Fourteen had sustained a second degree injury, and 16 a third degree injury. Out of five patients with third degree injuries who were treated by operation within the first three days, two survived. Two patients operated upon for complications after 10 days of conservative treatment died. The total mortality was 21%, but 56% for those who had received a third degree injury. Thirteen patients developed a stenosis (27% of those with gastroesophageal lesions). Esophageal strictures were dilatated with bougies, but stomach stenoses were treated by resection. Of the 12 patients treated by dilatation, 4 sustained perforations and 4 of them were free of symptoms for a considerable period of time (more than 4 years).
