Randomized Controlled Trial Comparative Study Clinical Trial
Devascularization procedure and DSRS: a controlled randomized trial on selected haemodynamic portal flow pattern in schistosomal portal hypertension with variceal bleeding.
The use of duplex studies for the portal tree has revolutionized the concepts of haemodynamic pathophysiology in the case of portal hypertensive bleeders. The identification of possible haemodynamic patterns in schistosomal bleeders, and the effects of devascularization procedure and distal lienorenal shunts on a selected haemodynamic pattern, are the aim of this work. ⋯ DSRS proved to be ideal for schistosomal patients with hepatopedal flow and splenic vein flow exceeding portal vein flow; since in addition to eliminating the high splenic flow out of portal circulation, it decreased the pressure in the gastroesophageal region. Other patterns with their frequencies and the suggested surgical procedures were also presented.

Randomized Controlled Trial Comparative Study Clinical Trial
Epidural analgesia attenuates the systemic stress response to upper abdominal surgery: a randomized trial.
The effects of combined general anaesthesia and epidural analgesia in various endocrine and metabolic parameters were studied before, during, at the end, and 72 h after upper abdominal surgery, in an effort to further elucidate the role of epidural analgesia in the endocrine and metabolic response. 50 patients were randomly assigned into groups A and B, which received general anaesthesia alone and combined general anaesthesia and epidural analgesia, respectively. The effects of surgical stress in the plasma concentration of ACTH (P <0.001), cortisol (P <0.01), aldosterone (P <0.05), FFA (P <0.05) and glucose (P <0.01) were significantly less pronounced in the group of patients who received combined general anaesthesia and epidural analgesia. However, there were no significant differences between the two groups in regard with plasma TSH, T3, T4, glucagon or Na+ concentration. These results indicate that the combination of general anaesthesia and epidural analgesia attenuate, but does not inhibit, the endocrine and metabolic response to upper abdominal surgery.

Jehovah's Witnesses are an enlarging religious community in the US and throughout the world. Members of this faith refuse administration of blood during medical or surgical therapy even if death may occur as a consequence. The surgeon is consequently faced with difficulties and moral dilemmas of caring for these patients. ⋯ The surgical care of Jehovah's Witnesses has become less of an operative risk over the last decade. There are now significant alternatives to the transfusion of blood, such as erythropoietin, iron dextran, aprotinin and Fluosol-DA 20%. Technological surgical developments and advances, such as the cell saver, argon beam coagulator, acute limited normovolemic hemodilution, autologous whole plasma fibrin gel, and controlled hypotensive anesthesia during anesthesia have contributed substantially to a reduction in the operative loss of blood. The time honored rule of hemoglobin of 10 g/dl and a hematocrit of 30% should not require strict adherence in the postoperative care of most patients. The acceptance of a lower transfusion trigger point of hematocrit of 22% and a hemoglobin of 7 g/dl can significantly reduce transfusion requirements without an increase in morbidity. Ethical considerations are discussed and evaluated when treatment restrictions, such as blood transfusion and other life-preserving therapies are limited by religious beliefs or living wills.

We have retrospectively analyzed the postoperative prognostic factors for 116 patients with stage I adenocarcinoma, with special reference to pleural retraction and intra-tumoral air-bronchogram imaged by computed tomography, which may represent the biological features of pulmonary adenocarcinoma for the retraction of surrounding tissues due to central necrosis and air space-lining growth, respectively. ⋯ These results suggested that, in stage I adenocarcinoma, the degree of malignant potential may be well figured by radiological imaging, with a significant affect on susceptibility of recurrence following complete resection.

Review Case Reports
Acute colonic intramural hematoma due to blunt abdominal trauma.
Trauma to the colon is uncommon and accounts for only 3-5% of all blunt abdominal injuries. Among them, intramural hematoma of the colon is a rare complication and the acute form is rarer than the chronic form. We report a 37-year-old man who presented with abdominal pain followed by intestinal obstruction due to a blunt trauma. ⋯ We conclude that acute colonic hematoma can be diagnosed by sonography and/or CT in contrast to the early reported cases, in the pre-CT era, when they could only be diagnosed at laparotomy. Endoscopy may also be helpful for diagnosis in some cases. Although expectant therapy may be successful in some cases, the majority of the cases may need operation.
