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.

National learning curve for laparoscopic hysterectomy and trends in hysterectomy in Finland 2000–2005

BACKGROUND Complications of laparoscopic hysterectomy (LH) have been evaluated with particular focus on quantities of urinary tract injuries. An earlier survey in the 1990s on LH in Finland indicated a decreasing trend in complications; our aim was to evaluate the current complications and hysterectomy trends. METHODS All hysterectomies in Finland performed for benign indication from 2000 to 2005 (n = 56 130) were included, data were obtained from the Finnish hospital care register. All major complications reported on LH were analysed; the data were collected retrospectively from the Patient Insurance Centre. RESULTS In 2000, the proportion of abdominal hysterectomy (AH) was 38%, vaginal hysterectomy (VH) 37% and LH 25%, whereas in 2005, the proportions were 26%, 45% and 29%, respectively. The overall incidence of major complications in LHs from 1992 to 1999 (LH n = 13 885) was 1.8% and from 2000 to 2005 (LH n = 13 942) it decreased to 1.0%. During the same time, urinary tract injuries decreased from 1.4% to 0.7%; in detail ureteral injuries decreased from 0.9% to 0.3%. CONCLUSIONS Laparoscopic and VHs have become more common in Finland than AH. Continuous instruction and training of the Finnish gynaecological surgeons has helped to diminish major complication rates and it seems that in LH, a plateau on the learning curve has been reached.

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.

Ten years of progress—improved hysterectomy outcomes in Finland 1996–2006: a longitudinal observation study

Objectives To study the outcome of various hysterectomies in 2 years 1996 (N =10110) and 2006 (N=5279). The hypothesis was that the change in operative practices in 10 years has resulted in improvements. Design 2 prospective nationwide cohort evaluations with the same questionnaire. Setting All national operative hospitals in Finland. Participants Patients scheduled to either abdominal hysterectomy (AH), vaginal hysterectomy (VH) or laparoscopic hysterectomy (LH) for benign disease. Outcome measures Patients’ characteristics, surgery-related details and complications (organ injury, infection, venous thromboembolism and haemorrhage). Results The overall complication rates fell in LH and markedly in VH (from 22.2% to 11.7%, p<0.001). The overall surgery-related infectious morbidity decreased in all groups and significantly in VH (from 12.3% to 5.2%, p<0.001) and AH (from 9.9% to 7.7%, p<0.05). The incidence of bowel lesions in VH sank from 0.5% to 0.1% and of ureter lesions in LH from 1.1% to 0.3%. In 2006 there were no deaths compared with three in 1996. Conclusions The rate of postoperative complications fell markedly in the decade from 1996 to 2006. This parallels with the recommendation of the recent meta-analyses by Cochrane collaboration; the order of preference of hysterectomies was for the first time precisely followed in this nationwide study. Trial registration The 2006 study was registered in the Clinical Trials of Protocol Registration System Data (NCT00744172).

Sexual functioning, quality of life and pelvic pain 12 months after endometriosis surgery including vaginal resection

Objective. To evaluate sexual function, quality of life and pelvic pain after endometriosis surgery including vaginal resection. Design. Prospective observational study with 12 months follow up. Setting. Regional central hospital and university hospital. Population. Twenty‐two patients with deep endometriotic nodules in the posterior fornix of the vagina undergoing complete excision of endometriosis, including vaginal resection. Methods. Sexual functioning was measured with the McCoy Female Sexuality Questionnaire, quality of life with a generic questionnaire (15D) and pain with a 10‐point visual analog scale. Questionnaires were completed before and 12 months after the surgery. Main outcome measures. Changes in sexual function scores, quality‐of‐life scores and pain. Results. Twelve months after surgery, the sexual satisfaction score was higher (p= 0.03) and the sexual problems score lower (p= 0.04) compared with baseline values. Health‐related quality‐of‐life scores for discomfort and symptoms (p= 0.001), distress (p= 0.04), vitality (p= 0.03) and sexual activity (p= 0.001), and the overall 15D score (p < 0.001), were significantly improved. The severity of all studied types of pain was significantly decreased (p < 0.05). Conclusions. Complete excision of endometriosis, including vaginal resection, seems to offer a significant improvement in sexual functioning, quality of life and pelvic pain in symptomatic patients with deeply infiltrating endometriotic nodules in the posterior fornix of the vagina. This surgery may be associated with complications and adverse new‐onset symptoms, and should be performed only after thorough consultation with the patient.

Quality of life and sexual function 1 year after laparoscopic rectosigmoid resection for endometriosis.

Aim  Endometriosis is relatively common condition in fertile women and may affect the alimentary tract. Laparoscopic rectosigmoid resection for endometriosis has been found to be both feasible and safe. The aim of the present study was to prospectively evaluate the quality of life and sexual function of patients who have undergone rectosigmoid resection for endometriosis.

Safety aspects of laparoscopic hysterectomy

Hysterectomy is one of the most frequently performed of all surgical operations and approximately 10,000 hysterectomies are performed annually in Finland (1). A lifetime risk of a woman to undergo hysterectomy has been 30% in the United States (2), 20% in Finland (1) and in the United Kingdom (3), but only 10% in Sweden (4) and Denmark (5). Traditionally the uterus has been removed by an abdominal or vaginal route. In spite of the lower complication rate in vaginal hysterectomies (6), abdominal hysterectomy has been the main method of hysterectomy in most of the countries. More than ten years ago 90–95% of hysterectomies were performed abdominally in Finland (1) and in Sweden (7), 70–80% in the United States (8) and in the United Kingdom (3) but only 40% in Austria (9). The optimum approach to hysterectomy would retain the advantages of the abdominal route, which include clear visualization and ease of manipulation of the adnexal structures, and to combine these features with the principal advantage of vaginal hysterectomy, namely avoidance of a large abdominal incision. Laparoscopic hysterectomy tries to combine these techniques and it has already influenced approaches to hysterectomy, offering a short recovery for the patient (10). How-

Pharmaceutical thrombosis prophylaxis, bleeding complications and thromboembolism in a national cohort of hysterectomy for benign disease

BACKGROUND Pharmaceutical thrombosis prophylaxis (PTP) with low-molecular-weight heparin (LMWH) is highly effective in preventing venous thromboembolic events (VTEs) and fatal pulmonary embolism. Important risk factors for VTEs are surgery and immobilization, along with malignancy. Many studies involving gynaecological malignancies show no increased risk for bleeding complications with PTP. Little is known about the PTP-associated risk for bleeding complications with hysterectomy for benign disease, or about current VTE incidence in the less-invasive hysterectomy methods. METHODS Our observational prospective national 1-year cohort from 1 January to 31 December 2006 in 53 hospitals represented 79.4% (5297 of 6645) of hysterectomies performed for benign cause in Finland in 2006. We evaluated PTP use and VTE incidence. Operative and post-operative bleeding complications were analysed with logistic regression adjusted for confounders: age, BMI, experience of the gynaecological surgeon, hospital type, indication for hysterectomy, uterine weight, operative haemorrhage, concomitant surgery, adhesiolysis and antibiotic prophylaxis. RESULTS Hysterectomies were performed by three main approaches: 2345 vaginal hysterectomies (VHs, 44%), of which 1433 were for uterine prolapse and 912 for other indications, 1679 laparoscopic hysterectomies (LHs, 32%) and 1255 abdominal hysterectomies (AHs, 24%). PTP was given to 64.8% of patients (3420 of 5279) and was identified as LMWH in 3313 patients (97%); 107 left unidentified. By type of hysterectomy, PTP was given in VH for uterine prolapse to 73.2% of patients, VH for other indication to 51.6%, in LH to 59.4% and in AH to 71.9%. For all hysterectomies analysed together, PTP doubled the odds for post-operative haemorrhage or haematoma. By type of hysterectomy, PTP associated with post-operative haemorrhage or haematoma in VH for prolapse [2.7% of PTP given, versus 0.8% of no PTP; odds ratio (OR): 4.82, 95% confidence interval (CI): 1.38-16.83]; and in AH (3.1% versus 1.4%; OR: 2.87, 95% CI: 1.03-7.98), and in AH also with post-operative transfusion (3.1% versus 1.4%; OR: 3.34, 95% CI: 1.41-7.88). For LH and VH for indications other than prolapse, the effect of PTP on post-operative haemorrhage was non-significant. For VH, the risk for post-operative haemorrhage fell with age. Operative mean haemorrhage with all hysterectomy types, and operative bleeding complications in AH and VH also fell with age. Obesity increased haemorrhage and operative bleeding complications for LH and VH, whereas post-operative bleeding complications were less for the obese in AH. VTEs were 6 of 5279 (0.1%): two PEs each occurred after AH and VH, and two deep venous thromboses after LH. CONCLUSIONS With a relatively wide PTP coverage (64.8%), VTEs were rare (0.1%). All affected had received PTP. Analysis of efficacy, meaning interpretation of how many VTEs or deaths were prevented, cannot be done from our observational study but related to safety in hysterectomy for benign disease, PTP associated with post-operative bleeding complications with AH and with VH for prolapse.
