- BACKGROUND:: Epidemiological reports on risk and prognostic factors in patients with mesenteric venous thrombosis (MVT) are scarce. METHODS:: Patients with MVT were identified through the inpatient and autopsy registry between 2000 and 2006 at Malmö University Hospital. RESULTS:: Fifty-one patients had MVT, diagnosed at autopsy in six. The highest incidence (11.3 per 100 000 person-years) was in the age category 70-79 years. Activated protein C resistance was present in 13 of 29 patients tested. D-dimer at admission was raised in all five patients tested. Multidetector row computed tomography (CT) in the portal venous phase was diagnostic in all 20 patients investigated, of whom 19 were managed conservatively. The median length of resected bowel in 12 patients who had surgery was 0.6 (range 0.1-2.2) m. The overall 30-day mortality rate was 20 per cent; intestinal infarction (P = 0.046), treatment on a non-surgical ward (P = 0.001) and CT not done (P = 0.022) were associated with increased mortality. Cancer was independently associated with long-term mortality: hazard ratio 4.03, 95 per cent confidence interval 1.03 to 15.85; P = 0.046. CONCLUSION:: Portal venous phase CT appeared sensitive in diagnosing MVT. As activated protein C resistance was a strong risk factor, lifelong anticoagulation should be considered.

Journal article (peer-reviewed)abstract
- Background: The Shouldice technique is the 'gold standard' of open non-mesh hernia repair. The aim of this study was to compare 5-year recurrence rates after Shouldice and laparoscopic transabdominal preperitoneal patch (TAPP) repair for primary inguinal hernia. Method: Men with a primary unilateral inguinal hernia were randomized to either Shouldice or TAPP operation. An independent observer scored the surgeons' performance. Follow-up comprised clinical examination after 1 year, a questionnaire after 2 and 3 years, and a clinical examination after 5 years. Results: Between February 1993 and March 1996, 1183 patients were included. Nine hundred and twenty patients were followed for 5 years, 454 in the TAPP group and 466 in the Shouldice group. Recurrences were evenly distributed between groups throughout the follow-up period. The cumulative recurrence rate after 5 years was 6.6 per cent in the TAPP group and 6.7 per cent in the Shouldice group. Postoperative pain was a risk factor for recurrence after Shouldice operation but not after TAPP repair. There was a correlation between a low surgeon's performance score and recurrence. Conclusion: The 5-year recurrence rate is acceptable, with no difference between TAPP and Shouldice repair. Poor operative performance resulted in a higher recurrence rate. The TAPP operation represents an excellent alternative for primary inguinal hernia repair.

Artificial neural networks in pancreatic disease.

- BACKGROUND: An artificial neural network (ANNs) is a non-linear pattern recognition technique that is rapidly gaining in popularity in medical decision-making. This study investigated the use of ANNs for diagnostic and prognostic purposes in pancreatic disease, especially acute pancreatitis and pancreatic cancer. METHODS: PubMed was searched for articles on the use of ANNs in pancreatic diseases using the MeSH terms 'neural networks (computer)', 'pancreatic neoplasms', 'pancreatitis' and 'pancreatic diseases'. A systematic review of the articles was performed. RESULTS: Eleven articles were identified, published between 1993 and 2007. The situations that lend themselves best to analysis by ANNs are complex multifactorial relationships, medical decisions when a second opinion is needed and when automated interpretation is required, for example in a situation of an inadequate number of experts. CONCLUSION: Conventional linear models have limitations in terms of diagnosis and prediction of outcome in acute pancreatitis and pancreatic cancer. Management of these disorders can be improved by applying ANNs to existing clinical parameters and newly established gene expression profiles.

Long-term function and manovolumetric characteristics after ileal pouch-anal anastomosis for ulcerative colitis

Journal article (peer-reviewed)abstract
- BACKGROUND: Long-term pouch function and physiological characteristics after ileal pouch-anal anastomosis (IPAA) are poorly described. The aim of this study was to undertake a prospective investigation of long-term pouch function and manovolumetric characteristics. METHODS: Forty-two patients with a median follow-up of 16 years after IPAA were included. Function was assessed using a questionnaire and a score was calculated ranging from 0 to 15 (15 being the worst). Manovolumetry was performed and pouchitis recorded. A paired analysis was conducted, as the results were compared with previous data for each patient. RESULTS: The median functional score was 3.5 (range 0-10) at 2 years and 5 (range 1-11) at 16 years (P = 0.013). Resting anal canal pressures were higher (P < 0.001) and squeeze pressures lower (P = 0.008) at long-term follow-up. Ileal pouch volumes at distension pressures of 10, 20 and 40 cm H(2)O were diminished at 16 years (P < 0.001, P = 0.005 and P = 0.058 respectively). The volume and pressure for first sensation and urge to defaecate were reduced. Increased age correlated positively with a poor functional score. A history of pouchitis did not affect functional or physiological characteristics. CONCLUSION: Ileal pouch function declines in the long term. The reasons are unclear, but the ageing process may have an impact.

Journal article (peer-reviewed)abstract
- BACKGROUND: The aim of the study was to analyse late gastrointestinal disorders necessitating hospital admission following rectal cancer surgery and to determine their relationship to preoperative radiation therapy. METHODS: Curatively treated patients participating in the Swedish Rectal Cancer Trial during 1987-1990, randomized to preoperative irradiation (454 patients) or surgery alone (454), were matched against the Swedish Hospital Discharge Registry. Hospital records for patients admitted with gastrointestinal diagnoses were reviewed. RESULTS: Irradiated patients had an increased relative risk (RR) of late small bowel obstruction (RR 2.49 (95 per cent confidence interval (c.i.) 1.48 to 4.19)) and abdominal pain (RR 2.09 (95 per cent c.i. 1.03 to 4.24)) compared with patients treated by surgery alone. The risk of late small bowel obstruction requiring surgery was greatly increased (RR 7.42 (95 per cent c.i. 2.23 to 24.66)). Irradiated patients with postoperative anastomotic leakage were at increased risk for late small bowel obstruction (RR 2.99 (95 per cent c.i. 1.07 to 8.31)). The risk of small bowel obstruction was also related to the radiation technique and energy used. CONCLUSION: Small bowel obstruction is more common in patients with rectal cancer treated with preoperative radiation therapy.
