Port site parasitic leiomyoma after laparoscopic myomectomy: a case report and review of the literature

Background: Uterine fibroids are the commonest benign gynecological tumors. Laparoscopic myomectomy is becoming increasingly popular as one of the surgical treatment options for symptomatic cases. Large tissues such as leiomyomas or even the uterus need to be morcellated in order to be retrieved from the abdominal cavity. Some of the morcellated fragments or small fibroids may be accidentally left in the abdominal cavity during the retrieval process. These may subsequently become implanted in the abdominal cavity, develop blood supply from the surrounding structures, and grow to form parasitic myomas with varied clinical presentation, depending on the location and size. Case presentation: A 47-year-old African woman presented to our hospital 6 years after laparoscopic myomectomy with a lower abdominal mass. Her work-up revealed an anterior abdominal wall mass consistent with uterine leiomyoma. She was scheduled for excision of the mass, which was subsequently histologically confirmed to be a uterine fibroid. Conclusions: Parasitic leiomyomas are a rare late complication of power morcellation following laparoscopic myomectomy or hysterectomy. Most patients present with an abdominal/pelvic mass and may need surgical excision to relieve the symptoms. Care should be taken during power morcellation to prevent excessive fragmentation of the tissues, some of which may become implanted and persist to form parasitic myomas. Moreover, effort should be made to retrieve all myoma fragments by carefully checking the abdominal cavity. Whenever possible, the morcellation should be done in a containment bag

Intravenous tranexamic acid as an adjunct haemostat to ornipressin during open myomectomy. A randomized double blind placebo controlled trial

Background: Myomectomy is a surgical technique used for removal of uterine fibroids and historically hysterectomy has represented the mainstay of treatment. The options of conservative surgical approaches mainly aim at retention of fertility but have to be balanced against potential risks such as haemorrhage; blood loss at myomectomy still remains troublesome with use of various pharmacologic agents yielding inconclusive results. This trial aimed to explore the benefit of combining ornipressin and tranexamic acid during open myomectomy. Study design: A randomized double blind placebo controlled trial. Methods: Women who satisfied eligibility criteria were enrolled into the study and randomized into one of two groups. The experimental group received 1 g of tranexamic acid diluted to 50 ml of saline administered at 100 ml per hour at cutting time (knife to skin). The control group received placebo diluted to 50 ml of saline administered at 100 ml per hour at cutting time. Both groups had five international units ornipressin diluted in 60 ml of saline administered during surgery. The primary outcome (blood loss) was assessed by determining the weight difference of dry and soaked swabs using a digital weighing scale by converting this to volume (ml). Operating time was noted from the time of uterine incision to the time of uterine closure. The need for transfusion was determined by anaesthetists’ assessment of acceptable blood loss and clinical assessment of vital signs. Post-operative stay was calculated from the time of extubation to 8 am on the day of discharge. Results: A total of thirty-four patients were randomized to two groups; 17 received ornipressin only and 17 received tranexamic acid and ornipressin. There was no difference in blood loss between the groups with a median blood loss in the ornipressin (n = 17) and ornipressin plus tranexamic acid arms of 398 ml (IQR: 251–630) ml and 251 ml (IQR: 158–501) ml respectively P = 0.361. Conclusions: Ornipressin administered along with tranexamic acid is not beneficial for blood loss reduction at open myomectomy. In settings such as ours where myomata are prevalent and severe anaemia rampant, blood donation and judicious use of scarce blood resources is key. Efforts to optimize preoperative haemoglobin levels and blood auto-donation seem the most promising options in pre-operative preparation prior to myomectomy.

Participating in a community of learners enhances resident perceptions of learning in an e-mentoring program: proof of concept

Background Community learning and e-mentoring, learning methods used in higher education, are not used to any extent in residency education. Yet both have the potential to enhance resident learning and, in the case of community learning, introduce residents to basic lifelong learning skills. We set out to determine whether residents participating in an Internet based e-mentoring program would, with appropriate facilitation, form a community of learners (CoL) and hold regular community meetings. We also determined resident and faculty perceptions of CoL and Internet sessions as effective learning experiences. Methods A six-month e-mentoring pilot was offered to 10 Radiology residents in the Aga Khan University Postgraduate Medical Education Program in Nairobi, Kenya (AKUHN) with a Professor of Radiology, located at University of Virginia, USA, acting as the e-mentor. Monthly Internet case-based teaching sessions were facilitated by the e-mentor. In addition, residents were coached by a community facilitator to form CoL and collectively work through clinical cases at weekly face-to-face CoL sessions. Event logs described observed resident activity at CoL sessions; exit survey and interviews were used to elicit perceptions of CoL and Internet sessions as effective learning experiences. Results Resident adoption of CoL behaviors was observed, including self-regulation, peer mentoring and collaborative problem solving. Analysis revealed high resident enthusiasm and value for CoL. Surveys and interviews indicated high levels of acceptance of Internet learning experiences, although there was room for improvement in audio-visual transmission. Faculty indicated there was a need for a larger multi-specialty study. Conclusions The pilot demonstrated resident acceptance of community building and collaborative learning as valued learning experiences, addressing one barrier to its formal adoption in residency education curricula. It also highlighted the potential of e-mentoring as a means of expanding faculty and teaching materials in residency programs in developing countries

Caesarian section rates and perinatal outcome at the Aga Khan University Hospital, Nairobi

Background: There has been a persistent rise in the rate of Caesarean sections over the years.Whether this rise is the cause of the decline in infant mortality and improved neonatal outcome still remains debatable. Objective: To compare the Caesarian section rate and the perinatal outcome at the Aga Khan University Hospital for the years 2001and 2004. Design: Retrospective study. Setting: The Aga Khan University Hospital, Nairobi. Main outcome measures: The total Caesarian section rates, their indication and the perinatal outcome. Results: The overall Caesarian section rate was 20.4% in 1996,25.9% in 2001and 38.1% in 2004.The rate among patients managed by their private obstetricians was 27.1% in 1996, 30.8% in 2001and 41.7% in 2004.Whilst among general patients, it was 14.7%,21.5% and 34.5% over the same period. The main indication for emergency Caesarian section was foetal distress, while that for elective Caesarian section was a previous uterine scar. The overall perinatal mortality rate improved from 25.2 per 1,000 births in 2001to 14.0 per 1,000 births in 2004 (P\u3c 0.001, 95%CL 8.58-30.62).The early neonatal mortality rate was 12.8 per 1,000 live births in 2001compared to 10.8 per 1,000 live births in 2004 (p=0.08, 95%CI 9.84-13.76). Conclusion: There has been a significant increase in Caesarian section rate over the years. Being a referral unit dealing with many high-risk patients some of whom are supervised elsewhere and with a significant ratio of private patients, the high rate of Caesarean section at the Aga Khan University Hospital is expected.The rise could also be due to early detection of foetal compromise and improved diagnostic facilities leading to timely intervention. However, there has been a significant improvement in the neonatal outcome over the same period of time. Whether this is an effect of the high Caesarean section rate is debatable and calls for further research to correlate the two

Uterine Necrosis After Uterine Artery Embolization for Symptomatic Fibroids

Introduction: Uterine artery embolization (UAE) is a minimally invasive intervention that is used in the treatment of fibroids. UAE can lead to complications including postembolization syndrome, postprocedure pain, infection, endometrial atrophy leading to secondary amenorrhea, and uterine necrosis. Uterine necrosis afer UAE is very rare and hence poses a clinical dilemma for any clinician in its identifcation and management. We document a case of uterine necrosis afer UAE and conduct a literature review on its causation, clinical features, and management principles. Case: A patient presented one month afer UAE with abdominal pain and abdominal vaginal discharge. Her work-up revealed features of possible uterine necrosis with sepsis and she was scheduled for a laparotomy and a subtotal hysterectomy was performed. She was subsequently managed with broad spectrum antibiotic and recovered well. Conclusion: Uterine necrosis afer UAE is a rare occurrence and we hope the documentation of this case will add to the body of knowledge around it. Teories that explain its occurrence include the use of small particles at embolization, the use of Contour-SE a spherical poly-vinyl alcohol, and lack of collateral supply to the uterus. Its symptoms may be nonspecifc but unremitting abdominal pain is invariably present. Finally although conservative management may be successful at times, surgical management with hysterectomy will be required in some cases. Te prognosis is good afer diagnosis and surgical management

Prevalence of genital chlamydia infection in urban women of reproductive age, Nairobi, Kenya

Background: Chlamydia trachomatis is one of the major causes of sexually transmitted infections throughout the world. Most infections are asymptomatic and remain undetected. Burden of disease in the Kenyan population is not well characterised. This study was done to define the prevalence of genital Chlamydia infection in a representative female population. Findings: A cross-sectional study design was employed. All women attending out-patient clinics (antenatal, gynaecology, family planning) and accident and emergency departments at two study sites over a five month period were invited to consent to completion of a questionnaire and vaginal swab collection. A rapid point-of-care immunoassay based test was performed on the swabs. Women who tested positive for Chlamydia were offered treatment, together with their partner(s), and advised to come for a follow-up test. A total of 300 women were tested. The prevalence of genital Chlamydia trachomatis was found to be 6% (95% CI 3.31% - 8.69%). The prevalence was higher in women who represented a higher socioeconomic level, but this difference was not significant (p=0.061). Use of vaginal swabs was observed to be a more acceptable form of sample collection. Conclusion: The prevalence of genital Chlamydia is significant in our female population. There is a justifiable need to institute opportunistic screening programs to reduce the burden of this disease. Rapid and low cost point-of-care testing as a potential component of sexually transmitted infection (STI) screening can be utilised.Publisher PDFPeer reviewe

One year symptom severity and health-related quality of life changes among Black African patients undergoing uterine fibroid embolisation.

BACKGROUND: The main aim in the treatment of symptomatic fibroids by various modalities including uterine fibroid embolisation (UFE) is to alleviate symptoms and ultimately improve the quality of life. The efficacy of this modality of treatment in Black African women with significant fibroid burden and large uterine volumes is not clear. The main objective of the study was to examine potential changes in symptom severity among Black African patients 1 year following UFE for symptomatic uterine fibroids in a resource-constrained setting, rated using a validated questionnaire (UFS-QOL). Secondary outcomes examined were changes in quality of life and potential associations with age, parity, uterine volume and fibroid number prior to UFE. Additional interventions after UFE were also recorded. METHODS: A prospective before and after study of Black African patients undergoing UFE was undertaken. Participants underwent pelvic MR imaging prior to UFE and completed the UFS-QOL, a validated condition-specific questionnaire at baseline and at 1 year. Ninety five participants were recruited and data from 80 completing 1 year of follow up were available for analysis of changes in the symptom severity scores. RESULTS: The mean reduction in symptom severity score was 29.6 [95% CI 23.6 to 35.6, P < 0.001] and the mean improvement in HRQOL score was 35.7 [95% CI 28.4 to 42.9, P < 0.001]. A greater number of fibroids identified prior to UFE was associated with a more substantial improvement in symptom severity score (rs = 0.28, n = 80, P = 0.013) and participants of higher parity reported a greater improvement in HRQOL score (r = 0.336, P = 0.002). Major and minor surgical interventions were needed in 5 (6.3%) and 10 (12.5%) participants respectively. CONCLUSIONS: UFE is associated with clinically useful and statistically significant symptom relief in Black African patients. Symptom improvement following UFE is not compromised by a large fibroid burden and the rate of subsequent intervention is within an acceptable range. UFE is a safe alternative and efforts are needed to widen access to this non-surgical treatment modality
