Treatment of pancreatic pseudocysts.

According to the Atlanta classification an acute pseudocyst is a collection of pancreatic juice enclosed by a wall of fibrous or granulation tissue, which arises as a consequence of acute pancreatitis or pancreatic trauma, whereas a chronic pseudocyst is a collection of pancreatic juice enclosed by a wall of fibrous or granulation tissue, which arises as a consequence of chronic pancreatitis and lack an antecedent episode of acute pancreatitis. It is generally agreed that acute and chronic pseudocysts have a different natural history, though many reports do not differentiate between pseudocysts that complicate acute pancreatitis and those that complicate chronic disease. Observation--"conservative treatment"--of a patient with a pseudocyst is preponderantly based on the knowledge that spontaneous resolution can occur. It must, however, be admitted that there is substantial risk of complications or even death; first of all due to bleeding. There are no randomized studies for the management protocols for pancreatic pseudocysts. Therefore, today we have to rely on best clinical practice, but still certain advice may be given. First of all it is important to differentiate acute from chronic pseudocysts for management, but at the same time not miss cystic neoplasias. Conservative treatment should always be considered the first option (pseudocysts should not be treated just because they are there). However, if intervention is needed, a procedure that is well known should always be considered first. The results of percutaneous or endoscopic drainage are probably more dependent on the experience of the interventionist than the choice of procedure and if surgery is needed, an intern anastomosis can hold sutures not until several weeks (if possible 6 weeks).

Effects of surface irregularities on flow resistance in differently shaped arterial stenoses.

The combined influence of an asymmetric shape and surface irregularities has been explored in a computational study of flow through arterial stenoses with 48% areal occlusion. Contrary to the conclusion of an earlier investigation, namely that the resistance to laminar flow through a stenosed artery is being reduced in the presence of surface irregularities, the present predictions demonstrate that the flow resistance is practically unaffected by surface irregularities at low Reynolds numbers, whereas an excess pressure drop up to 10% above that for a smooth stenosis is observed for higher Reynolds numbers. For a given areal occlusion, the flow resistance is reduced with increasing degree of stenosis asymmetry and this effect may more than outweigh the influence of surface irregularities. This effect is moreover prevailing throughout the entire range of Reynolds numbers considered.

[Laparoscopic splenectomy].

From 1995 to 1998, 14 patients have been treated with laparoscopic splenectomy. Seven patients had immune thrombocytopenic purpura (ITP), six hereditary spherocytosis and one chronic myelomonocytic leukaemia with trombocytopenia. 12 of the patients had normal or nearly normal sized spleen. Median duration of surgery was 156 minutes and the median postoperative hospital stay four days. All operations were completed laparoscopically. Three patients had postoperative fever without any sign of infection, one developed urinary retention and one was readmitted with pneumonia. The patient with chronic myelomonocytic leukaemia died 15 days postoperatively from an intracerebral bleeding. Two patients suffer from relapse of trombocytopenia, one is treated with steroids. Laparoscopic splenectomy can be performed safely in patients with normal sized spleen with all the advantages of minimal access surgery. However, problems related to identification of accessory spleens and splenectomy in patients with splenomegali, should be further evaluated.

[Laparoscopic colorectal surgery. The first experiences from the Central Hospital of Akershus].

Between November 1993 and August 1997, 49 patients (29 women and 20 men) were selected to 51 laparoscopic and laparoscopic-assisted colonic or rectal operations. Five operations were converted to open surgery because of technical problems and adhesions. 46 operations could be performed as planned. The median age was 67 years (20-88 years). A variety of procedures were carried out, including construction of deviating sigmoideostomas without resection (n = 17), segmental resections of colon (n = 15), rectopexi (n = 6), stoma closure (n = 4), abdominoperineal resection (n = 3) and suture of an iatrogenic perforation of the large bowel (n = 1). Eight of the patients with a bowel resection had carcinoma. The median duration of the procedures was 112 minutes (38-293 minutes) and the length of hospitalisation eight days (2-40 days). 13 patients (28%) developed complications. One of these patients died and four were reoperated. These first experiences show that we are able to perform a variety of colorectal surgery laparoscopically. An experienced, well organised operating team with modern laparoscopic equipment is essential to this type of surgery. Prospective, randomised studies have to be done to assess the efficacy of the laparoscopic approach.

[Does preoperative urethral catheter increase the risk of complications in transurethral prostate resection?].

In a material consisting of 243 patients treated with transurethral prostate resection 76 had preoperatively been drained for urine by indwelling urethral catheter. Delayed recovery or increased risk for complications due to the resection could not be demonstrated in this group compared to 167 patients without use of preoperative catheter. Peroperative antibiotic prophylaxis is to recommend in patients operated upon directly after catheter drainage.

Gastrointestinal disturbances in marathon runners.

To determine the prevalence of various gastrointestinal disturbances related to long-distance running and its effect on weight, diet and everyday digestive problems, we gave a questionnaire to 279 leisure-time marathon runners, comprising 10% of the participants in a local marathon race. Their answers disclosed a prevalence of dietary changes, weight reduction and altered bowel habits (mainly looser stools and/or more frequent defaecation) of 37, 38 and 48% respectively. A quarter reported earlier long lasting gastrointestinal problems, which improved in 41% of the runners after they started regular training. Thirty-four percent experienced gastrointestinal disturbances during or after running, 20% to such an extent that it seriously affected their performance.
