Review of current practice to establish success after vasectomy

BACKGROUND: This study aimed to examine the criteria used by surgeons in a district general hospital to confirm success following vasectomy, to establish the proportion of men undergoing vasectomy in whom the procedure was unsuccessful according to those criteria, and to evaluate their subsequent management. METHODS: All 15 surgeons performing vasectomy indicated that they required two consecutive azoospermic postvasectomy semen specimens before they advised couples that the vasectomy was successful. Results of postvasectomy semen analysis (PVSA) for all 240 primary vasectomies performed over a 12-month interval were analysed. Minimum follow-up was 30 (range 30-42; median 37) months. RESULTS: At follow-up 72 men (30 per cent) had not returned postvasectomy samples that fulfilled the criteria, including 18 who were azoospermic on the first PVSA 3 months after vasectomy but who failed to produce a second specimen. In 24 men (10 per cent) who failed to comply with the PVSA protocol, there was no documentation of any further action being taken. No pregnancies were reported in the partners of the study group during this interval and only one patient underwent repeat vasectomy. CONCLUSION: The results suggest that the strict requirement of two consecutive azoospermic postvasectomy semen specimens may be unjustified, leads to a high level of non-compliance and causes unnecessary delay in confirming success of the procedure.     

Reversal of vasectomy using a macroscopic technique: a retrospective study.

Eighty-five men underwent vasectomy reversal in our department between 1981 and 1994. All operations were performed without the aid of magnification. The results of semen analysis was available in 66 and the patency rate was 74%. A postal survey was sent to patients we could follow up, and among those who replied the pregnancy rate was 41% (16/39 respondents). These results are similar to those found by others using a macroscopic reversal of vasectomy and since the operator does not rely on the use of a microscope, which both incurs an added cost and requires extra expertise, we feel that the operation as described has a part to play in the management of men seeking reversal of vasectomy.     

Should vasectomy reversal be performed in men with older female partners?

PURPOSE: An assumption exists that men with older female partners who seek treatment of post-vasectomy infertility should undergo in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI) rather than vasectomy reversal. Although several studies have reviewed ICSI success rates with advancing maternal age, to our knowledge none has compared them to outcomes for vasectomy reversal in men with older partners. MATERIALS AND METHODS: The records of all patients with ovulating partners older than 37 years who underwent vasectomy reversal from 1994 through 1998 were reviewed. Patients were contacted to establish pregnancy and birth rates. Costs of vasectomy reversal, testicular sperm extraction, IVF and ICSI were obtained from the financial office of our institution. RESULTS: A total of 29 patients underwent vasectomy reversal with a followup of 3 to 59 months (median 25). Median male age was 46 years (range 37 to 67) and median female age was 40 years (range 38 to 48). A total of 5 pregnancies and 4 live births were achieved. In the 23 patients followed for more than 1 year the pregnancy rate was 22% and live birth rate was 17%. Using this 17% birth rate at our $4,850 cost for vasectomy reversal the cost per newborn was $28,530. In comparison, using the 8% birth rate per cycle of ICSI for women older than 36 years at a cost of $8,315 for testicular sperm extraction and 1 cycle of IVF with ICSI, the cost per newborn was estimated at $103,940. CONCLUSIONS: Vasectomy reversal appears to be cost-effective to achieve fertility in men with ovulating partners older than 37 years.     

PATIENT CHARACTERISTICS ASSOCIATED WITH VASECTOMY REVERSAL

PURPOSE: More than 30 million couples throughout the world are using vasectomy as a method of birth control. It is estimated that up to 6% of men who undergo voluntary sterilization will eventually request reversal, despite the high cost and relatively low success rate of the procedure. We identified characteristics that predict which vasectomy patients may request reversal. We also examined the cost and effectiveness of pre-vasectomy sperm cryopreservation followed by intrauterine insemination as an alternative method of achieving pregnancy. MATERIALS AND METHODS: We reviewed medical charts of 365 patients who underwent vasectomy and 290 who underwent vasectomy reversal between 1990 and 1997. Data were collected on patient age at the time of vasectomy, religion, occupation, wife employment status, number of marriages, number of children, reason for reversal, and number of years between vasectomy and reversal. Based on previously reported values, pregnancy rates and cost per successful pregnancy were estimated for vasectomy reversal surgery, and compared with a calculated cost per pregnancy for sperm cryopreservation and intrauterine insemination. RESULTS: Patient factors significantly associated with increased vasectomy reversal included younger age at time of vasectomy (p < 0.001) and a wife who worked outside the home (p < 0.001). Vasectomy reversal occurred 12.5 times more often (95% confidence interval [CI] 7.6 to 20.7) in men who underwent vasectomy in their 20s than in men who were older. Men whose wives were not employed requested reversal 0.48 times as often (95% CI 0.33 to 0.71) as those whose wives worked. Men who were younger at vasectomy tended to wait longer before reversal (median 10 years) than other patients (p < 0.001). At 10 years our calculated pregnancy rates and cost per pregnancy were 44% and $12,727 for vasectomy reversal, and 41% and $9,512 for intrauterine insemination with banked sperm (3 attempts). CONCLUSIONS: Patients who requested vasectomy reversal most often chose voluntary sterilization at a younger age. We believe that younger men should be given better pre-vasectomy counseling. However, the success rate and cost-effectiveness of sperm cryopreservation before vasectomy, with subsequent intrauterine insemination, may make this nonsurgical alternative desirable for younger couples who choose vasectomy even when properly informed about reversal rates.     

Should all urologists performing vasectomy reversals be able to perform vasoepididymostomies if required?

PURPOSE: While vasectomy reversal is a highly successful procedure 10% to 30% of reversals may fail. Despite the general consensus that an epididymal obstruction may occur following a vasectomy and that some men should undergo vasoepididymostomy (VE) rather than vasovasostomy (VV), the practice of many urologists in our region has been to offer only VV for vasectomy reversal. We examined the potential causes for vasectomy reversal failure in patients who had undergone VV without an attempt at VE. MATERIALS AND METHODS: We conducted a retrospective review of patients who had undergone redo vasectomy reversal from January 1999 to September 2001. A total of 22 patients underwent redo reversal with a minimum followup of 2 years. The medical records of all patients were then reviewed. Patients and partners seen postoperatively in the clinic were questioned regarding any pregnancy or deliveries. RESULTS: We examined 22 patients who had undergone redo vasectomy reversal. Of 22 patients 9 (40.9%) underwent repeat VV, 8 (36.3%) underwent bilateral VE for a presumed unrecognized epididymal obstruction and 5 (22.7%) had a combination of VE and VV. Of the 44 reproductive units studied 23 (52.3%) had a failed vasal anastomosis while 21 (47.7%) had an unrecognized epididymal obstruction. Based on semen analysis patency was observed in 75% of patients who had undergone vasovasostomy as a redo procedure. A patency rate of 60% was found in patients who underwent vasoepididymostomy and vasovasostomy unilaterally, and patency rates for bilateral VE were 63%. CONCLUSIONS: Our study indicates that a large proportion of men (48%) have an epididymal obstruction as the etiology for vasectomy reversal failure. We recommend that all surgeons offering vasectomy reversals be able to offer VE if required based on intraoperative findings to serve the patient adequately as well as his partner and their future fertility.     

Need for sperm retrieval and cryopreservation at vasectomy reversal

PURPOSE: Controversy exists on whether to obtain sperm for cryopreservation routinely at vasectomy reversal. With recent improvements in in vitro fertilization with intracytoplasmic sperm injection, it is now possible to obtain a small amount of testicular tissue for cryopreservation in the event of reversal failure. However, to our knowledge no studies exist of who is most likely to benefit from this procedure. MATERIALS AND METHODS: We reviewed 84 consecutive vasectomy reversals performed by 1 surgeon (J. I. S.) between July 1996 and March 2000 with followup available for 77. We grouped cases by procedure as vasovasostomy, vasoepididymostomy and vasovasostomy with vasoepididymostomy as well as bilateral or unilateral. Sperm was retrieved at reversal in 15 of 46 vasovasostomy (none used), 11 of 18 vasoepididymostomy (3 used) and 13 of 20 vasovasostomy with vasoepididymostomy (none used) cases. RESULTS: The overall anastomotic patency rate after unilateral or bilateral vasovasostomy, unilateral vasovasostomy with contralateral vasoepididymostomy and unilateral or bilateral vasoepididymostomy was 96%, 83% and 57%, respectively. The natural pregnancy rate without in vitro fertilization was 57%, 50% and 14%, respectively. The most recent vasoepididymal anastomoses were performed by the Berger triangulation technique with a 78% patency and 25% pregnancy rate. Only 8% of men with banked sperm eventually used it for assisted reproductive techniques, in whom unilateral or bilateral vasoepididymostomy failed in all. CONCLUSIONS: We currently do not recommend routine sperm retrieval for cryopreservation in men who undergoing vasovasostomy. We encourage men who require bilateral vasoepididymostomy to bank sperm at reversal. In men who undergo vasovasostomy with vasoepididymostomy we base the decision on preoperative counseling and intraoperative findings.     

IgG antisperm antibodies attached to sperm do not correlate with infertility following vasovasostomy

The sperm of 12 men postvasovasostomy was tested for antisperm antibodies by means of a mixed antiglobulin reaction (MAR) test. Agglutinating antibodies were found in 58% of these patients: 50% of the men whose partners became pregnant and 75% of those whose partners did not become pregnant. No significant difference in the level of antibody attachment could be found between the fertile group and the infertile group. Damage to the testis and epididymis following vasectomy seems more likely to interfere with subsequent fertility following vasectomy reversal.     

Detection of testicular endocrine abnormalities and their correlation with serum antisperm antibodies in men following vasectomy

We measured the serum gonadotropin response to gonadotropin-releasing hormone in 25 men who underwent vasectomy 2 to 64 months before the study. Ten age-matched fertile men were used as controls. Baseline serum follicle-stimulating hormone, luteinizing hormone and testosterone levels were not significantly different between vasectomized men and controls. However, mean serum follicle-stimulating and luteinizing hormone responses to an intravenous bolus injection of 100 mcg. gonadotropin-releasing hormone were significantly greater in the vasectomy group (p equals 0.008 and 0.003, respectively). There was no correlation between these responses and the interval after vasectomy. Serum antisperm antibodies were present in 13 vasectomized men (52 per cent) using enzyme-linked immunosorbent assay and microagglutination techniques. A significant correlation (p equals 0.003) was found between the presence of serum antisperm antibodies and a normal follicle-stimulating hormone response to gonadotropin-releasing hormone stimulation. Of 13 patients with demonstrable antisperm antibody titers 9 (69 per cent) had normal follicle-stimulating hormone responses, compared to only 1 of 12 (8 per cent) without identifiable antisperm antibody titers. Our data suggest that certain men following vasectomy have abnormalities in seminiferous tubule and Leydig cell functions of the testes. These abnormalities are unrelated to the interval after vasectomy and are not identifiable with routine static hormonal measurements. In addition, serum antisperm antibodies are most likely to be present in men who demonstrate normal seminiferous tubular activity after vasectomy.     

Improving ART initiation among men who use HIV self‐testing in Malawi: a qualitative study

IntroductionHIV self‐testing (HIVST) increases HIV testing uptake among men; however, the linkage to antiretroviral therapy (ART) among HIVST users is low. Innovative strategies for ART initiation are needed, yet little is known about the unique barriers to care experienced by male HIVST users, and what ART‐related interventions men desire.MethodsWe conducted semi‐structured in‐depth interviews with cisgender men (≥15 years) in Malawi who tested HIV positive using HIVST between 2018 and 2020, as well as interviews with their female partners (≥15 years) who distributed the HIVST kits. Medical records from seven facilities were used to identify respondents. We included men who received HIVST from a health facility (primary distribution) and from sexual partners (secondary distribution). Interview guides focused on unique barriers to ART initiation following HIVST and desired interventions to improve linkage and initiation. Interviews were audio recorded, translated and transcribed to English, and analysed using constant comparison methods in Atlas.ti v.8.4. Themes were compared by HIVST distribution strategy. Data were collected between 2019 and 2020.ResultsTwenty‐seven respondents were interviewed: eight male/female dyads (16 respondents), eight men without a female partner and three women who represented men who did not participate in the study. Among the 19 men represented (16 men interviewed in person, three represented by secondary report from female partners), seven received HIVST through primary distribution, 12 through secondary distribution. Six men never initiated ART (all secondary HIVST distribution). Barriers to ART initiation centred on the absence of healthcare workers at the time of diagnosis and included lack of external motivation for linkage to care (men had to motivate themselves) and lack of counselling before and after testing (leaving ART‐related fears and misconceptions unaddressed)––the latter was especially true for secondary HIVST distribution. Desired interventions were similar across distribution strategies and included ongoing peer mentorship for normalizing treatment adherence, counselling messages tailored to men, outside‐facility services for convenience and privacy, and facility navigation to help men understand how to navigate ART clinics.ConclusionsMale HIVST users face unique challenges to ART initiation, especially those receiving HIVST through secondary distribution. Male‐tailored interventions are desired by men and may help overcome barriers to care.     

A novel instrument-independent no-scalpel vasectomy - a comparative study against the standard instrument-dependent no-scalpel vasectomy

An instrument-independent no-scalpel vasectomy (IINSV) technique is reported. This technique does not use the standard specific instruments, but comparatively retains the advantages of minimally invasive instrument-dependent no-scalpel vasectomy (IDNSV). Between July 1999 and June 2002, 449 men were prospectively randomized to be vasectomized at two hospitals in Taipei. Of those who accepted, 215 underwent IDNSV at one hospital and the remaining 234 underwent IINSV at the other. The intra-operative conditions of each group were recorded. The postoperative pain and life conditions were self-reported through a questionnaire that had been carefully designed prior to the operations, in which the pain level was assessed using a 10-cm visual analogue scale under varying situations. Men vasectomized using the IINSV method experienced less operation time and postoperative complications (haematomas, infections and granulomas) (p < 0.05). There were no significant differences between the two groups with respect to incision length, postoperative pain, pain at coitus, time of return to work, time of resuming intercourse, self-reported satisfaction in sexual life, postoperative psychological status, postoperative body weight change and vasectomy failure as evidenced by sperm analysis (p > 0.05 for all items). Thus, the IINSV technique can offer an alternative option for vasectomists whenever the specific instruments of standard no-scalpel vasectomy are unavailable. The IINSV technique shortens the operation time and reduces the incidence of operative complications when compared with the IDNSV technique, while still retaining the advantages of minimally invasive vasectomy.     

A different female partner does not affect the success of second vasectomy reversal

The aim of the study was to determine whether the pregnancy rate with the same female partner or younger partners was higher compared with different or older partners after undergoing repeated vasectomy reversal. A total of 44 patients were enrolled in the present study. The cause of reversal in patients with the same partner was the desire to have more children in 14 cases, the loss of a child in 7 cases, and the desire for a son in 7 cases. Patients were asked about pregnancy and childbirth during follow-up visits and by telephone or mail. Following microsurgical vasectomy reversal, patency was observed in 38 men (86.4%). Twenty-five of the couples (56.8%) achieved pregnancy without any artificial conception technique. We did not observe a significant difference in the pregnancy rate (57.1% vs 56.3%, P=.954) between patients with the same or a different female partner. In the multivariate model used, partner age was the only independent predictor for pregnancy. Patients with a partner less than 35 years old had a 4.1-fold greater chance (odds ratio, 4.13; 95% confidence interval, 1.06-16.10; P=.041) of pregnancy than those with a partner 35 years old or older. The area under the receiver operating characteristics curve for partner age was 73.0% (95% confidence interval 56.8-89.2, P=.011). Our findings suggest that repeat microsurgical vasectomy reversal still remains a reasonable choice for patients with different female partners. However, it should be considered that the likelihood of achieving pregnancy after repeat vasectomy reversal may decrease with advancing age of the female partner.     

Hydrozele,Spermatozele und Vasektomie

Indications for hydrocele and spermatocele treatment are based on diagnosis with high-resolution ultrasonography. It must be clear whether hydrocele or spermatocele lead to impairment of the patient – asymptomatic findings do not need correction. In case of younger men, the wish for children must be taken into account as both surgical procedures may lead to infertility, especially spermatocele resection may lead to epididymal obstruction. Advantages and disadvantages of the intervention must be discussed with the patient in detail. In men with a planned vasectomy, the physician must be certain that the patient understands the definitive character of this form of contraception. Men who are not aware of this condition or have conflicts with their partners may not be the best candidates for surgical vasectomy. All three treatment options (hydrocelectomy, spermatocele resection, and vasectomy) may be accompanied by fertility preservation procedures (e.g., cryopreservation of semen prior to surgery). Alternatively, the surgery should not be performed if any doubts exist. Postoperative management includes follow-up examinations and in case of vasectomy after 6–12 weeks and several ejaculations at least two semen analysis with proven azoospermia after centrifugation (or <100,000 immotile spermatozoa) should be documented. Compliance of men is best when this follow-up appointment is already scheduled at the time of surgery.     

VASECTOMY REVERSAL ASSOCIATED WITH INCREASED REACTIVE OXYGEN SPECIES PRODUCTION BY SEMINAL FLUID LEUKOCYTES AND SPERM

Purpose

Reactive oxygen species, which are primarily produced by leukocytes, are generally detrimental to sperm. High reactive oxygen species levels are found in men with abnormal sperm function. Since men often have poor sperm characteristics and infertility after vasectomy reversal, fertile men to determine if reactive oxygen species were elevated in the former group.

Materials and Methods

We studied semen samples of men with proved fertility (39) and those with previously proved fertility who had undergone vasectomy reversal (45). The presence of leukocytes was determined by Bryan-Leishman staining. Reactive oxygen species endogenous activity was monitored by luminol dependent chemiluminescence in washed cells, including all cells in the semen, and Percoll density gradient purified sperm.

Results

After vasovasostomy men had significantly lower sperm concentration, motility and computerized motility measurements than fertile men. Mean reactive oxygen species in washed seminal cells after vasovasostomy was 684 relative light units per second compared to 49 for fertile controls (p <0.0001). Density gradient purified sperm had 53 and 0.64 relative light units per second, respectively (p <0.0001). When men with leukocytospermia were excluded from analysis, differences between the groups remained, although 9 times more reactive oxygen species were detected in men after vasectomy reversal with than those without leukocytes in semen.

Conclusions

Higher levels of reactive oxygen species are found in washed seminal cells and purified sperm after vasectomy reversal than in those of fertile men. Although leukocytes are probably a significant source of reactive oxygen species in these groups, they may not account for all of the increased reactive oxygen species after vasovasostomy. Low motility after vasectomy reversal may be related to the detrimental effects of reactive oxygen species produced by leukocytes or sperm, even in men without clinical leukocytospermia.     

Urinary excretion of calcitonin gene-related peptide in males with hot flushes after castration for carcinoma of the prostate.

OBJECTIVE: The majority of men who undergo surgical or medical castration due to prostatic carcinoma develop vasomotor symptoms with hot flushes. The mechanisms behind these symptoms are poorly understood. One possible explanation is a release of the vasodilatory peptide calcitonin gene-related peptide (CGRP) from perivascular nerves, which seem to be involved in the mechanisms behind vasomotion and sweating in postmenopausal women. The aim of this report was to investigate whether CGRP is involved in vasomotion in men after castration therapy. MATERIAL AND METHODS: Twenty-four hour urine excretion of CGRP was analysed in 15 men with prostatic carcinoma, using radioimmunoassay before and 3 months after surgical or medical castration. RESULTS: Eleven of the 15 men developed hot flushes during the observation period of 3 months. Twenty-four hour urine excretion of CGRP did not change significantly after castration, either in the group as a whole or in those 11 men who developed hot flushes. CONCLUSIONS: Even though we did not observe any significant changes in 24-h urine excretion of the potent vasodilator CGRP after castration it is possible that serum levels of CGRP increase during hot flushes, without having an effect on the 24-h urine excretion of the peptide.     

Population-based outcomes after 28,246 in-hospital vasectomies and 1,902 vasovasostomies in Western Australia

OBJECTIVES: To examine trends in vasectomy and vasovasostomy, and the surgical complications and factors associated with reversal after vasectomy, and paternity after vasovasostomy. PATIENTS AND METHODS: Procedure rates were estimated from 1980 to 1996 in the population of Western Australia. Linked hospital morbidity records were used in the follow-up of men after vasectomy to estimate the risks of complications and reversals. Records of vasovasostomies were linked to the paternity field on birth registrations. Independent effects of the study factors were examined using Cox regression. RESULTS: There was little net change in vasectomy rates, whereas vasovasostomy rates increased in men aged 30-49 years. Risks of surgical complications were low and decreased for vasovasostomy. At 12-15 years after vasectomy, the risk of reversal levelled at 2. 4% in the total cohort and at 11.1% in men aged 20-24 years. The risk of vasovasostomy was 69% greater after vasectomy performed in 1994-96 than in 1980-84 (P = 0.011). The factors strongly associated with reversal were age < 30 years and being single, divorced or separated at the time of vasectomy. Paternity was achieved after an estimated 53% of vasovasostomies. Successful reversal was more likely if the man was younger at vasectomy and the time elapsed was comparatively short. Compared with vasovasostomies performed in 1980-84, the success rate of those in 1994-96 was almost four times higher. CONCLUSION: Population rates of vasectomy are stable but the risk of seeking a reversal has increased. Outcomes after vasovasostomy have improved. Care should be taken during the counselling of men before vasectomy, and especially in those aged <30 years.     

Experience with sperm counts following vasectomy

The records of Aberdeen men requesting vasectomy between 1978 and 1981 were studied and a sample of men were interviewed about 3 years after the operation; 85% completed the standard requirements for seminal analysis and were given the "all clear"; two-thirds were cleared after sending 2 samples and usually within 20 weeks after vasectomy; 10% of men sent at least 1 sample but were never cleared and the remaining 5% ignored the requirements. Information from 70 men (63 interviews, 7 questionnaires) gave some indication of reasons, often multiple, for incomplete or non-compliance; these included embarrassment, ambiguous feelings about having more children, inadequate understanding of reproductive physiology and blind faith in the surgeon.     

Vasectomy, inflammation, atherosclerosis and long-term followup for cardiovascular diseases: no associations in the atherosclerosis risk in communities study.

PURPOSE: Although human studies have failed to reveal an increased risk of clinical cardiovascular disease in men who undergo vasectomy, the possibility exists that an association may be detectable only after a long followup, or it may be more evident for subclinical than clinical disease. We assessed the association of vasectomy with inflammation and coagulation factors, carotid intimal-medial thickness, carotid plaque, prevalent peripheral arterial disease, and incident coronary heart disease and stroke in the Atherosclerosis Risk in Communities cohort. MATERIALS AND METHODS: Included in the study were 3,957 white men 45 to 64 years old who were free of coronary heart disease at the Atherosclerosis Risk in Communities (ARIC) baseline examination in 1987 to 1989. Data on vasectomy was collected at baseline by self-reporting. High resolution B-mode ultrasound was done to assess carotid intimal-medial thickness and carotid plaque. The cohort was followed an average of 9 years for incident cardiovascular events. RESULTS: Average time since vasectomy was 16 years. Approximately 20% of the population had undergone vasectomy 20 years or more ago at baseline. Multivariate analysis showed no association of vasectomy status with inflammation or coagulation factors, peripheral arterial disease, carotid plaque, carotid far wall thickness, incident coronary heart disease or stroke. Associations were unaffected by the time since vasectomy. CONCLUSIONS: There is no evidence in this population based sample of men indicating that vasectomy is related to atherosclerosis even after more than 20 years of followup.     

Current practice in the management of vasectomy reversal and unobstructive azoospermia in Merseyside & North Wales: a questionnaire-based survey

OBJECTIVE: To investigate the current incidence of vasectomy reversal procedures, the techniques used and which practitioners use them. PATIENTS AND METHODS: Using a questionnaire, 130 general surgeons and urologists practising in Merseyside and North Wales were surveyed. RESULTS: The response rate was 74%, with 24 urological surgeons and 14 general surgeons undertaking vasectomy reversal. Annually, urological surgeons carried out significantly more procedures than did general surgeons, at 8.5 and 5.3 (P = 0.029), respectively. They were also more likely to use double-layer closure and microsurgical techniques, whilst significantly less likely to use stents. Urologists reported significantly greater patency rates, at 76% and 52% (P = 0.017), respectively, with no significant differences in subsequent pregnancy rates (30% vs 25%). Only one practitioner checked tubal patency in the female partner before vasectomy reversal. CONCLUSIONS: The use of vasectomy reversal is a cost-effective treatment for men wanting paternity after vasectomy. The technique used by the clinician and proper audit of the results require close attention; it would also appear to be obvious that all the partners of men seeking a vasectomy reversal should have their fertility status established before reversal, something that is clearly not done at present.     

Preoperative cardiac risk management

Numerous strategies exist for preoperative cardiac testing before patients undergo vascular operations. Potential adverse effects of evaluation and cardiac intervention should be considered before undertaking screening studies. We recently analyzed the adverse outcomes of preoperative cardiac evaluation and intervention before vascular operations in patients treated at the Denver Department of Veterans Affairs Medical Center. During the 12 month study period, 161 patients were scheduled to undergo major vascular operations; 153 patients came to operation. The decision to pursue a cardiac evaluation was made without a defined protocol. Forty two men, aged 68+/-9 years underwent comprehensive preoperative cardiac evaluations Sixteen (38%) patients had untoward events related to cardiac evaluation, including eight patients (19%) who refused vascular surgery after cardiac screening and/or intervention. Other complications included prosthetic graft infection, pseudoaneurysms (2), sternal wound infections (2) amputations (2), renal failure and brain anoxia. Extensive cardiac evaluation prior to vascular operations can result in morbidity, delays, and refusal to undergo vascular surgery. The underlying indication for vascular operations and the local iatrogenic cardiac complication rates must be considered before ordering special studies.     

Partnership, sexuality, and sexual disorders in morbidly obese women: consequences of weight loss after gastric banding

Background: A study was performed to determine what consequences surgery for morbid obesity has on sexual attitudes and partnership in obese female patients. Method: Semi-structured interviews concerning sociodemographic data, sexuality and relationship were conducted on 82 female patients preoperatively and at least 1 year postoperatively. Results: Physical appearance played the main role in the decision to undergo weight reduction surgery in only 17% of the study patients. Postoperatively, half of the patients were satisfied with their physical appearance 1 year after surgery, the other half not. Preoperatively, 44% of the patients stated that sexuality with their partners was satisfying and the frequency of sexual intercourse was regular. Postoperatively, 63% of the patients stated that they enjoyed sex more, compared with 12% of the patients who enjoyed sex less than before surgery. Postoperatively, 20% of the patients reported that partnership had changed positively, 10% negatively. Conclusions: The results indicate that many of the sexual problems in obese individuals are the result of an underlying lack of self-esteem, unsatisfactory relationships, or collective stigmatization of obese individuals. Binge eating, often found in morbidly obese patients, seems to be less the result of or compensation for sexual problems but is more likely to stem from other psychosocial or psychological problems.
