The Heart, Great Vessels, Esophagus
1. Wounds of the Heart. Report of
Twelve Cases.
Daniel C. Elkin, Atlanta.
Twelve cases of stab wound of
the heart are presented. The method of diagnosis and technique of operation are
described. The causes of death are given and suggestions are made for lowering
the mortality.
2. Further Data on the Production of a
New Blood Supply to the Heart by Operation.
Claude S. Beck, Cleveland.
Résumé of the experimental
work to date with colored lantern slide demonstration.
3. The Reduction of Cardiac
Irritability by the Epi-cardial Application of Drugs as a Protection in Cardiac
Surgery.
frederick R. mautz, Cleveland.
(By Invitation)
An experimental study has been made of a
number of drugs with reference to their absorption through the epicardium.
Certain of these drugs are readily absorbed and have a profound action upon a
surface layer of myocardium without serious impairment of cardiac action as a
whole. Certain of the drugs also affect nervous structures at the base of the
heart. The use of drugs is suggested in surgical procedures on the heart as a
means of reducing the number of extrasystoles and danger of ventricular
fibrillation.
4. An Experimental Study of
Intrapericardial and Extrapericardial Adhesions with Reference to Operation
Upon the Heart.
Robert M. Hosler and John E. Williams, Cleveland.
(By Invitation)
Experiments were done upon dogs, and adhesions
were established between the heart and pericardium; between pericardium and
diaphragm; and between heart, pericardium, and diaphragm. These dogs were studied
over a period of two and one-half years. Conclusions reached were:
Intrapericardial or extrapericardial adhesions do not produce circulatory
embarrassment, nor does the combination of the two. These adhesions do not lead
to hypertrophy of the heart. In no experiment did circulatory failure occur.
5. Obliteration of the Superior Vena
Cava of Undetermined Origin.
Alton Ochsner and J. Leonard Dixon, New
Orleans.
(By Invitation)
Abst. Case report: Female, 23
years, with suffused face, prominent veins on chest and in neck; duration 3
years following trauma. Venous pressure, arms 35 cm. of water, legs 16 cm.
Operation: Mediastinotomy with exploration. Superior vena cava found to be
dense cord ¾ cm. in diameter. Recovery with improvement. Review of the literature.
6. Remarks on the Anatomical Structure
of the Esophagus and Its Frailties.
William Lerche, Cable, Wisconsin.
7. Diagnosis and Treatment of Benign
Ulcers of the Esophagus with Case Report.
H. R. Decker. Pittsburgh.
Abst. Classification
and symptomatology of ulcers of the esophagus are discussed. Diagnosis is
established by endoscopic examination, and in doubtful cases by biopsy.
Treatment by local applications to the ulceration combined with dietary
measures are usually sufficient to accomplish healing. At times gastrostomy is
needed, rarely esophagectomy may be indicated. Case reported in which
esophageal ulcer developed following surgical treatment of duodenal ulcer.
Gastrostomy required in course of treatment.
8. The Surgical Management of Congenital
Atresia of the Esophagus with Traeheo-esophageal Fistula : Report of a Case.
N. L. Leven, Minneapolis.
(By Invitation)
Abst. The paper briefly reviews
the literature, symptomatology, diagnosis, and previously proposed surgical
treatments. Although 80% of cases of congenital atresia of the esophagus have
associated tracheo-esophageal fistulae, only simple cases not complicated by
fistulae have been successfully treated by surgery. In these complicated cases
the prognosis has been considered hopeless, since no case has survived longer
than four weeks. A surgical procedure is described which was used in a case of
congenital atresia of the esophagus with tracheo-esophageal fistula that
survived 95 days.
9. Bronchoscopic Aspects of Bronchial
Tumors, with Special Reference to So-called "Bronchial Adenoma."
Chevalier L. Jackson, Philadelphia.
Abst. Although a positive biopsy will be obtained in
75% of cases of bronchial carcinoma, bronchoscopy is also of real value when no
tissue is obtained. In the negative cases it is of importance to know that the
larger bronchi are free from growth, while in the cases with positive biopsy
findings bronchoscopy gives valuable additional information as to exact
location and proximal extent of the lesion. "Bronchial adenomas" at first
glance are nearly always considered to be adenocarcinomas. Further study has
shown them not to be truly malignant. They are amenable to treatment by
conservative broncho-scopic measures such as forceps removal, radon
implantation and electrocoagulation.

Surgery of the Lungs and Mediastinum
10. An Experimental Study of the
Physiologic Changes Following Total Pneumonectomy.
B.
N. Carter and J. J. Longacre, Cincinnati.
(By Invitation)
Abst. These studies were carried
out on dogs who had recovered from the operations for removal of one of their
lungs. Especial attention was directed to the study of their response to
exercise.
11. Experiences with One-stage Lobectomy
for Bronchiectasis.
E.
J. O'brien, Detroit.
Abst. 14 consecutive lobectomies
have been performed for bronchiectasis with only one death. A modification of
the Brunn-Shenstone technique used. Suction drainage through 3 catheters
has caused filling of the hemithorax with the remaining lobe within 24 hours.
There have been no hemorrhage from the stump, no persisting fistulae and no
empyemas except for small encapsulated ones.
12. Lobectomy and Pneumonectomy in
Bronchiectasis and Cystic Disease of the Lung.
E.
D. Churchill, Boston.
Abst. Report based on 40 cases of completed lobectomies with a
mortality rate of 5%.38 cases performed by present methods had a
mortality rate of 2.6%. Both one and two stage operations have been employed,
16 of the former and 23 of the latter. Two stage procedure differs from that of
Alexander in several important points. Indications for the type of operation to
be performed will be discussed. Both methods have their indications.
13. Compensatory Changes Occurring in the
Thorax and Its Contents Following Total Ablation of One Lung.
William F.
Rienhoff, Jr., Baltimore.
An analysis is presented of the effects of the
removal of one lung upon the thoracic cage and its contents. This analysis is
based upon a series of 12 cases in which total pneumonectomy was performed, and
two cases of post-traumatic atrophy of one lung.
The absence of latent untoward physiological
effects upon the cardio-respiratory systems is discussed and the mechanism of
obliteration of the remaining dead space following total removal of the lung is
described.
14. Tumors of the Chest Derived
from Elements of the Nervous System.
W.
DeW. Andrus, New York.
Abst. Since the "family tree" of
the various elements of the nervous system has been worked out, it has become possible
not only to classify their tumors according to the embryological derivation of
the parent tissue, but to correlate their structure, and in many instances
their degree of malignancy, with the various stages of embryological
development represented by their component elements. Cases of chest tumors
illustrating this point are presented, including neuro-epithelioma,
neuroblastoma, ganglioneuroma, neurofibroma and neurinoma or schwannoma.
15. Intrathoracic Xanthomatous
Neoplasms.
E.
W. Phillips, Rochester, N. Y.
Abst. Presentation of reports of
two cases of intrathoracic xanthomatous tumors with a review of the literature.
