[Wandering spleen].

The spleen is well fixed below the left side of the diaphragm. Wandering spleen is a rare condition of unknown pathogenesis. The wandering spleen is most often localized in the lower abdomen or pelvis. The diagnosis may be difficult if wandering spleen is not suspected. Often a wandering spleen can be palpated in the lower abdomen. In the rare cases of torsion of the splenic vascular pedicle, wandering spleen becomes symptomatic, and splenectomy should be performed. We report a case of a 20-year-old female treated with splenectomy because of torsion of the vascular pedicle.

The arterial sling operation: one-year follow-up.

BACKGROUND: Coronary artery bypass graft surgery with total arterial revascularization, particularly the use of bilateral in situ internal thoracic arteries, is considered an improved treatment of patients with ischemic heart disease. The sling operation connects the internal thoracic arteries with the radial artery, creating an arterial arcade with double inlet of blood to the peripheral vascular bed. In this paper we present 1-year follow up of angiographic and clinical results of the arterial sling operation. METHODS: The arterial sling operation was performed in 28 patients in the period from October 2000 to September 2001, and all patients were offered an angiographical and clinical examination 1 year postoperatively. All angiograms were systematically reviewed by an interventional cardiologist and a cardiac surgeon. RESULTS: Twenty-three patients participated in the 1-year angiographic follow up. Of these 3 patients had a fully open arterial sling, 15 patients had stenosis or occlusion of one segment, and 5 patients had occlusion or stenosis of 2 segments of the radial artery. Eight of the total 93 peripheral anastomoses were occluded. The 1-year graft patency rate was 91.4%. CONCLUSIONS: The arterial sling operation is safe and the one year patency rate is high. Although one or two segments of the arterial sling may degenerate due to competitive blood flow, this does not affect blood flow in the vascular bed in patients without disease progression. However, arterial revascularization should be performed in a way to minimize competitive flow.

[Esophageal resections in Denmark 1997-2000].

INTRODUCTION: We evaluated the changes in Denmark since the 1980s in the incidence, management and outcome of oesophageal resections. MATERIAL AND METHODS: The national patient hospital register and discharge information from the hospitals were examined for the number of oesophageal resections performed, the length of the postoperative stay, readmission, postoperative complications, and hospital mortality in the period 1/1-1997 to 30/6-2000. RESULTS: Twenty-six departments in 18 hospitals performed 476 resections. Five hospitals accounted for 92% of all the resections performed. In three hospitals, the resections were carried out in three different departments and 18 departments performed fewer than four resections per year. The postoperative stay was 19.2 days. The frequency of surgical complications was 19% and hospital mortality was 10.7%. DISCUSSION: The small number of oesophageal resections performed in many departments in Denmark is not in accordance with international recommendations, which say that the operation should be performed in high volume centres by experienced oesophageal surgeons, including thoracic surgeons, surgical gastroenterologists, and thoracic anaesthesiologists. On these results, it is recommended that the operation is performed in few centres and by few surgeons in multidisciplinary teams.
