OBJECTIVE To analyze mortality following groin hernia operations. SUMMARY BACKGROUND DATA It is well known that the incidence of groin hernia in men exceeds the incidence in women by a factor of 10. However, gender differences in mortality following groin hernia surgery have not been explored in detail. METHODS The study comprises all patients 15 years(More)
BACKGROUND Chronic pain is common after herniorrhaphy, but the effect of surgical technique (mesh versus non-mesh repair) and the social consequences of the pain have not been established. The aim of this study was to analyse chronic postherniorrhaphy pain and its social consequences in young males operated on for an indirect inguinal hernia with a(More)
BACKGROUND Recent studies have suggested that MBP does not lower the risk of postoperative septic complications after elective colorectal surgery. This randomized clinical trial assessed whether preoperative MBP is beneficial in elective colonic surgery. METHODS A total of 1505 patients, aged 18-85 years with American Society of Anesthesiologists grades(More)
BACKGROUND In specialised centres, local anaesthesia is almost always used in groin hernia surgery; whereas in routine surgical practice, regional or general anaesthesia are the methods of choice. In this three-arm multicentre randomised trial, we aimed to compare the three methods of anaesthesia and to determine the extent to which general surgeons can(More)
OBJECTIVE To analyze the relative risk of reoperation for recurrence using 3 anesthetic alternatives, general anesthesia (GA), regional (spinal-, epidural-) anesthesia (RA), and local anesthesia (LA), and to study time trends for various anesthetic and operative methods, as well as other risk factors regarding reoperation for recurrence. BACKGROUND The(More)
OBJECTIVE To establish a register of inguinal hernia surgery that allows audit and analyses of data from several centres. DESIGN Prospective recording of data on a common protocol. SETTING Eight Swedish hospitals. SUBJECTS All groin hernia operations done for patients over 15 years old from January 1992 to December 1994. MAIN OUTCOME MEASURES(More)
BACKGROUND The reoperation rate after recurrent groin hernia surgery is more than twice that recorded for primary groin hernia procedures. The aim was to define the outcome from routine redo hernia surgery by analysing a large population-based cohort from a national hernia register. METHODS All recurrent groin hernia operations registered in the Swedish(More)
The mild cognitive decline associated with type 2 diabetes (T2DM) has been suggested to be reversible with improved glycemic control. In order to characterise this cognitive decline and study the effects of improved glycemic control we have studied patients with T2DM (N=28) and healthy control subjects (N=21). One group of patients with diabetes (N=15) were(More)
During the period 1971-1975 284 patients were treated for adenocarcinoma of the colon or rectum; 52% were aged 70 years or more, and 37% had incurable disease at the time of diagnosis. When staged according to Dukes' classification, tumours of the right colon (coecum and ascending colon) were more advanced than those in other parts of the colon and rectum(More)
BACKGROUND Occupational exposures and physical activity have been considered as risk factors for the development of colorectal cancer. METHODS A case-control study on working conditions and the risk of colon and rectal cancer was performed in southeastern Sweden during 1984-86. Involved were 177 patients, 98 with colon cancer and 79 with rectal cancer,(More)
