FINHYST, a prospective study of 5279 hysterectomies: complications and their risk factors.

BACKGROUND: Hysterectomy guidelines highlight an increase in urinary tract injuries with laparoscopic hysterectomy (LH). This national survey analyses complications of LH, abdominal hysterectomy (AH) and vaginal hysterectomy (VH). METHODS: A prospective cohort undergoing hysterectomy for benign indications during 2006 was drawn from 53 hospitals in Finland; all communal hospitals participated. Detailed questionnaires covered surgical data and intra- and post-operative major and minor complications, for which risk factors were analysed by a multivariate logistic regression model adjusted for surgical data and patient characteristics. RESULTS: Major complications rates in AH (n= 1255, 24%), LH (1679, 32%) and VH (2345, 44%) were 4.0, 4.3 and 2.6%, and total complications rates were 19.2, 15.4 and 11.7%, respectively. Logistic regression showed no statistically significant differences between approaches for any organ injuries or other major complications. Most bladder and bowel injuries (88 and 83%), but not ureter injuries (10%), were recognized intra-operatively. The ureter injury rate was low after LH (0.3%), as it was after other types of hysterectomy. Compared with LH, AH increased the odds of wound infection, and was an independent risk factor for urinary infections and febrile events. Compared with AH, LH and VH both presented a higher risk for pelvic infection; surgically treated equally often regardless of the type of hysterectomy. No differences in complications emerged between LH and VH. Obesity was a risk factor for many infections. Surgical adhesiolysis [odds ratio (OR) 2.41, 95% confidence interval (CI) 1.38-4.21] was the strongest single risk factor for major complications as a whole. Bladder injury was associated with a history of caesarean section (OR 4.01, 95% CI 2.06-7.83) and with a large uterus ≥500 g (OR 2.88, 95% CI 1.05-7.90), while bowel injury was associated with adhesiolysis (OR 29.07, 95% CI 7.17-117.88). CONCLUSIONS: FINHYST is a large prospective hysterectomy study illustrating actual complications. Whenever possible, hysterectomy should be minimally invasive.

FINHYST 2006--national prospective 1-year survey of 5,279 hysterectomies.

BACKGROUND: In Finland, the number of hysterectomies during one decade has decreased by 34%. The national prospective FINHYST study in 1996 showed abdominal hysterectomy (AH) as being most common: 58%. In Finland since 2002, vaginal hysterectomy (VH) has been most preferred, with laparoscopic hysterectomy (LH) surpassing AH in 2005. METHODS: FINHYST 2006 is a national prospective hysterectomy study in which all hospitals collaborated from 1 January to 31 December 2006. Questionnaires, completed by gynaecologists, covered their experience, patient characteristics and surgical data. RESULTS: The 5279 hysterectomies distributed by approaches were 44% VHs, 32% LHs and 24% AHs. Less than 2% were subtotal. The main indications for hysterectomy were myomas (33%), uterine prolapse (28%) and menorrhagia (21%). The main indication for VH was not related to uterine prolapse in 39%. Bilateral salpingo-ooforectomy was performed in 36% of AHs, 32% of LHs and 2% of VHs. Antibiotic prophylaxis was used in 97%, and thrombosis prophylaxis in 65%. Haemorrhage was least and operation time shortest with VH, and hospital stay and sick leave were shortest after LH. CONCLUSIONS: In Finland, less invasive approaches comprise 76% of hysterectomies. This trend has resulted nationally in shortening of hospital stay and of convalescence time.

Tension-free vaginal tape and laparoscopic mesh colposuspension in the treatment of stress urinary incontinence: immediate outcome and complications--a randomized clinical trial.

BACKGROUND: The purpose of the study was to evaluate the immediate outcome and complications of the tension-free vaginal tape (TVT) and laparoscopic mesh colposuspension (LC) procedures in the treatment of female stress urinary incontinence (SUI). METHODS: One hundred and twenty-eight patients suffering from urodynamically confirmed SUI were recruited to this multicenter, randomized clinical trial. After randomization there were seven drop-outs--121 patients were operated upon: 70 patients in the TVT group and 51 in the LC group. The patients were evaluated according to the study protocol before operation and 6 weeks after it. The independent sample t-test and the Mann-Whitney U-test were used to calculate statistical differences between the study groups. RESULTS: Immediate cure rates, defined as negative stress test with 300 mL saline in the bladder, were similar (92.9% in the TVT group and 88.2% in the LC group; p = ns). Return to normal voiding was faster in the TVT group (9.2 h in the TVT group vs. 24.4 h in the LC group; p = 0.004). Fewer analgesics were used in the TVT group and hospital stay was shorter in this group. Complication rates associated with the procedures were similar and the number of complications was small. CONCLUSIONS: The immediate outcome of both procedures is the same. The rates of complications were similar. However, the TVT procedure seems to be less invasive and requires fewer hospital resources than LC.
