[Gastrointestinal hemorrhage].

Acute digestive system haemorrhage is a recurrent cause of hospitalization. As to the upper segment of the digestive system, ulcerous peptic disease is often the cause of this pathology, above all in Western Countries. As to the lower segment, colic diverticula and angiodysplasy represent the most common cause.

[Invasion of the chest wall in primary lung neoplasms].

The authors analyse a series of 5 patients who underwent pulmonary and parietal resection between 1990 and 1993 due to non.microcytoma bronchogenic carcinoma with invasion of the thoracic wall. The patients comprised four men and one woman aged between 45 and 69 years old.

[Palliative endoscopic intubation of esophago-gastric neoplastic stenosis: analysis of factors that may influence immediate results].

The paper examines a series of 172 patients undergoing endoscopic intubation with plastic stent due to unoperable esophago-gastric tumoral stenoses during the period 1980-1991. An analysis of the data enabled the following conclusions to be drawn: (1) The majority of perforations occur during the treatment of distal stenoses (15%), anastomotic stenosis (20%) and extrinsic compression stenoses (23% vs 7% in the case of stenosing primary esophageal neoplasia). (2) Severe respiratory problems may occur during treatment of cervical stenoses.

[Liver injury in abdominal trauma. Review of the literature and personal observations].

In patients who suffered abdominal trauma, the liver is the most frequently involved organ, except the spleen. The % rises from 1520% to 30% if trauma is closed or open. Liver injury may spread from a simple parenchymal contusion to a break in vessels or biliary ducts.

[Popliteal artery entrapment syndrome. Discussion of a case].

The paper reports a case of popliteal artery entrapment syndrome (3rd type) associated with poststenotic aneurysm with a single painful ischemic attack. Diagnosis was made following an accurate anamnesis and clinical examination using invasive and non-invasive instruments. Surgical therapy consisted of resection of the gastrocnemius muscle followed by a graft to the self inverted saphena vein.
