Late volume changes in retrosternal colon bypass.

Esophageal obstruction by malignancy, chemical burns, or other less common entities presents a challenge for the surgeon. Either for esophageal substitution after esophageal resection or as a bypass for the obstructed esophagus, colon interposition is often the best available option. Massive colonic enlargement requiring resection of the interposed dilated colon developed recently in 2 of our patients who had a colon bypass 22 and 10 years earlier, respectively.

Percutaneous drainage of lung abscess.

Most lung abscesses are successfully treated with antibiotics. However, occasional patients with lung abscesses that drain poorly, causing persistent fever and toxic symptoms, may require surgical intervention. Lobectomy is the most frequent surgical procedure. Some patients are debilitated and have underlying medical conditions such as heart disease, chronic pulmonary disease, or liver disease that may render surgical intervention risky. Recently there have been reports of percutaneous drainage of lung abscess with good results. We have successfully carried out percutaneous drainage of lung abscess in 4 patients and an infected bulla in 1. All patients had failed to respond to therapy with antibiotics and postural drainage. There was prompt disappearance of the fluid level in the cavity, decline in temperature, and abatement of toxic symptoms with drainage. The cavities closed gradually over the next 6-12 weeks. The patients tolerated the chest tube well and there were no side effects from the tube drainage. Percutaneous tube drainage is the surgical treatment of choice in the medically complicated patient with a poorly draining lung abscess.

Axillosubclavian vein thrombosis produced by retrosternal thyroid.

Several causes of axillosubclavian vein thrombosis have been described. Trauma to the subclavian vein by pacemaker wires or central venous lines as well as the so-called effort thrombosis have been recognized as frequently diagnosed precipitating factors. A patient is herein presented with thrombosis of the subclavian vein caused by a giant substernal thyroid compressing the innominate vein.

Treatment of displaced fractures of the sternum.

An easy technique is presented for the treatment of simple transversal fractures of the sternum when loss of alignment of the fractured extremities occurs. This technique produces instant relief and will avoid open reduction and wiring in most instances of uncomplicated fractures.

Transesophageal irrigation for the treatment of mediastinitis produced by esophageal rupture.

Esophageal rupture in the thorax, unless small and contained, is followed by the early onset of fulminant mediastinitis. When the rupture occurs in the cervical esophagus, mediastinitis will also occur if cervical drainage is delayed and the infection is allowed to spread along the periesophageal planes towards the mediastinum. The purpose of this article is to report the good results obtained in the treatment of life-threatening sepsis from esophageal rupture with the combination of continuous per oral transesophageal irrigation of the mediastinum and drainage of the irrigating fluid by accurately positioned chest tubes connected to a wall-suctioning system. When the patient cannot swallow, mediastinal irrigation is accomplished via a nasogastric tube positioned by the upper esophagus proximal to the perforation. Irrigation by mouth was also used for the treatment of cervical perforations with the drainage tubes positioned in the neck. With this method in eight patients, sepsis has invariably been controlled, and in six cases, in which no irreversible damage to the esophagus existed, the perforations have healed spontaneously. There was no death resulting from mediastinitis, which is most often the lethal factor in esophageal rupture.

Operative complications of abdominal vagotomy.

To assess the incidence of operative complications, mortality, and accuracy of vagotomy in transabdominal vagotomy, 733 cases were reviewed. Statistics are compared with those of other authors. A loose comparison of patients operated on by resident surgeons versus those operated on by attending surgeons is also made. Our preference for immediate microscopic examination of vagotomy specimens is stressed. One unusual complication is described.

The subxiphoid approach in the treatment of pericardial effusion.

Subxiphoid pericardiotomy for diagnosis and treatment of pericardial effusion is a safe procedure. Not only does it appear to be safer than aspiration, but it yields more information because of its ability to obtain pericardial tissue. The recurrence rate of pericardial effusion is lower using subxiphoid pericardiotomy. For these reasons it is the technique of choice for diagnosis and treatment of nontraumatic pericardial effusion.
