Long-term steroid treatment: a potential risk factor for uterine rupture during pregnancy?

AIM: Uterine rupture during pregnancy is a rare but life threatening event in Obstetrics, with potentially catastrophic consequences for both the fetus and the mother. There are few published case reports that investigate the possible association between long-term steroid treatment and uterine rupture during the antenatal period. CASE REPORT: A 33-year-old G2P1 woman with obstetrical history of one previous transverse low-segment caesarean section presented at the 30th week of gestation with severe abdominal pain which started spontaneously one hour before. She had medical history of pemphigus under long-term treatment with prednisolone. Clinical examination showed acute abdomen while the fetus developed heart rate decelerations. Emergency caesarean section via Pfannenstiel incision under general anaesthesia was performed. Uterine rupture was recognised with localization not at the scar of the previous caesarean section but at the left posterolateral site of the uterine fundus. A healthy premature male infant with an excellent Apgar score and weight of 1510 gr. was delivered by a low-segment caesarean section. Surgical repair of the site of the rupture with isolated sutures followed. There was no need for hysterectomy as hemorrhage was controlled and hemodynamic stability of the woman was restored. DISCUSSION: Uterine rupture should be included in the differential diagnosis by all obstetricians not only during labour but in acute abdominal pain during the antenatal period as well.

Surgical management of complex atypical endometrial hyperplasia in a woman with rare genitourinary anomalies: unicornuate uterus with rudimentary horn, ipsilateral ectopic ovary and pelvic kidney.

AIM: According to the so far published literature, only one case of endometrial cancer in a patient with unicornuate uterus has been reported. This is a case report study, presenting a rare case of complex atypical endometrial hyperplasia in a woman with unicornuate uterus and multiple genitourinary anomalies. CASE REPORT: A 43-year old G1P1 woman presented with episodes of menometrorrhagia and anemia. She had previous surgical history of laparoscopy due to infertility, in which she was diagnosed with unicornuate uterus with a rudimentary left uterine horn and ipsilateral ectopic ovary in the anatomic place of the left kidney. Dilatation and curettage was performed. Histology showed complex atypical endometrial hyperplasia. The patient underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy, in an extremely interesting operation due to the multiple genitourinary anomalies. The uterus with a 6-centimeter uterine myoma and the adnexae were removed en block. Great effort was put into dissecting the left fallopian tube which arised from the cervix and via the rudimentary horn led to the left ectopic ovary that was located at the left kidneys' anatomic space. The patient recovered well and final histology was negative for malignancy. DISCUSSION: All necessary imaging examinations have to be scheduled prior to surgical intervention in order to give valuable anatomic information in cases of women diagnosed with Mullerian abnormalities.

Bilateral primary ovarian non-Hodgkin's lymphoma and fertility preservation: 5-year follow-up.

AIM: Primary ovarian non-Hodgkin's lymphoma is a very rare disease. Median age at diagnosis is estimated at 42 years, something that leads to fertility preservation issues in many cases. This was a case report study, presenting a rare case of bilateral primary ovarian non-Hodgkin's lymphoma. CASE REPORT: A 38-year old nulliparous woman, underwent exploratory laparotomy because of bilateral ovarian masses. Left salpingooophorectomy, partial omentectomy and excision of an ovarian mass of the right ovary was performed. Great effort in order to preserve healthy ovarian tissue of the right ovary as well as the right fallopian tube was given, due to fertility reasons. Final histology showed bilateral diffuse large B-cell primary ovarian non-Hodgkin's lymphoma. Postoperatively, the patient underwent chemotherapy with the CHOP regimen in combination with rituximab. Five years after initial diagnosis, the patient remains well with normal menstrual cycle, without evidence of recurrence. DISCUSSION: Fertility preservation issues in some cases of rare gynecological malignancies could be managed via minimally invasive oncological approach.

Ovarian cancer diagnosed during pregnancy: clinicopathological characteristics and management.

The aim of this study was to discuss the diagnostic and therapeutic dilemmas in cases of pregnant women with adnexal masses, reporting an interesting case with synchronous literature review. The patient, a gravida 2, para 1, 37 year-old woman was diagnosed with a large unilateral adnexal lesion during a scheduled third trimester ultrasound assessment. A large papillary papule with a network of blood vessels showing decreased resistance in blood flow was noticed as well. Surgical intervention revealed ascitic fluid and a large cystic mass arising from the right ovary. Cesarean section and right salpingooophorectomy, including the mass, were performed. Frozen section biopsy was positive for malignancy. Total hysterectomy and left salpingo-oophorectomy, total omentectomy, biopsies from the pelvic peritoneum, pelvic/para-aortic lymphadenectomy and appendicectomy followed. Histology showed mucinous ovarian adenocarcinoma Grade I Stage Ic according to FIGO classification. Surgical intervention, in cases of persisting adnexal lesions, is often necessary, even during pregnancy.

Uterine angioleiomyoma causing severe abnormal uterine bleeding.

BACKGROUND: Angioleiomyoma or angiomyoma or vascular leiomyoma is an unusual benign mesenchymal neoplasm. The authors present a rare case of large uterine angioleiomyoma causing severe abnormal uterine bleeding. CASE: The patient, a 53-year-old, gravida 2, para 2, premenopausal Greek woman presented with a complaint of severe abnormal uterine bleeding. On gynecologic examination there was a palpable pelvic mass. Preoperative computer tomography (CT) of the abdomen and pelvis revealed an intra-abdominal mass 25 x 15 cm with abnormally increased vascularization. She underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy, total omentectomy and elective pelvic lymph node dissection. Histopathology revealed uterine angioleiomyoma. Follow up 84 months after initial surgery showed no evidence of recurrence. CONCLUSION: Despite the type of surgery, patients with uterine angioleiomyoma have very low risk of recurrence and excellent prognosis.

Tension-free vaginal tape obturator versus Ajust adjustable single incision sling procedure in women with urodynamic stress urinary incontinence.

OBJECTIVE: To assess the efficacy and complications of inside-out transobturator tension-free vaginal tape (TVT-O) in comparison with a single incision sling procedure (Ajust) for the treatment of urodynamic stress urinary incontinence. STUDY DESIGN: Prospective closely matched controlled study. In total, 171 patients were included in the study: 86 women underwent the TVT-O procedure, while in other 85 cases the Ajust procedure was performed. Subjective and objective cure, improvement and failure rates, mean operative time, hospital stay and incidence of complications were assessed. RESULTS: There was no statistically significant difference between the two groups for age, body mass index, parity, menopausal status and severity of prolapse. No major intraoperative complications occurred. There was no significant difference in the mean operative time and the duration of hospital stay between the two groups. The mean follow-up time of the study was 22.3 months (range 12-36 months). For the TVT-O group the objective cure rate was 86%, the improvement rate was 5.9% and the failure rate was 8.1%, while the subjective cure rate was 82.6%. For the Ajust group the objective cure rate was 84.7%, the improvement rate was 4.7%, 10.6% of patients showed no change in their symptoms and the subjective cure rate was 81.2%. CONCLUSIONS: The Ajust sling procedure presents success rates, at 22 months' mean follow up, comparable to the TVT-O method. Both techniques seem to be safe and effective for the treatment of urodynamic stress urinary incontinence.

Preimplantation genetic diagnosis in marfan syndrome.

Marfan syndrome (MFS) is a systemic hereditable disorder of the connective tissue with mainly cardiovascular manifestations, such as aortic dilatation and dissection. We describe a case of a 32-year-old Caucasian woman, clinically asymptomatic with MFS who presented for genetic consultation to prevent the transmission of disease to her offspring. She underwent controlled ovarian stimulation (COH), in vitro fertilization (IVF) combined with preimplantation genetic diagnosis (PGD), and a singleton pregnancy with positive fetal heart rate was revealed. At 34 weeks' gestation she delivered vaginally a healthy premature male infant weighting 2440 gr. The patient remained asymptomatic during pregnancy, delivery, and 3 months postpartum. It is has to be mentioned that the availability of PGD is essential to prevent the transmission of disease to the next generation.

Immunohistochemical study of inhibin A and B expression in placentas from normal and pathological gestations.

OBJECTIVE: The aim of the study was to examine, by an immunohistochemical method, the distribution of Inhibin-A and -B, in placentas from normal and pathological gestations. MATERIALS AND METHODS: Sixty-two specimens of placental tissue were examined: i) ten cases from early gestations, ii) 28 cases from mature placentas, iii) six cases associated with intrauterine growth restriction, iv) four cases associated with diabetes mellitus and v) 14 placentas from gestations with fetal chromosome abnormalities. The expression of Inhibin A and B was studied by automatic Ventana method. RESULTS: i) Early gestation specimens: Inhibin A (+) immunoreaction was observed in the syncytiotrophoblast (8/10 cases) and in the intermediate trophoblast (6/10 cases). Inhibin B (+) immunoreaction was observed in the syncytiotrophoblast (10/10 cases) and in the intermediate trophoblast (4/10 cases), ii) Normal mature placentas: Inhibin A (+) immunostain was observed in 2/28 cases in the syncytiotrophoblast and in 7/28 cases in the intermediate trophoblast. Inhibin B (+) immunostain was observed in 28/28 cases in the syncytiotrophoblast and in 18/28 cases in the intermediate trophoblast. iii) Placentas associated with intrauterine growth restriction: Inhibin A (+) immunostain was observed in the intermediate trophoblast in 2/6 cases. Inhibin B (+) immunostain was observed in 5/6 cases in the syncytiotrophoblast and in 4/6 cases in the intermediate trophoblast. iv) Placentas associated with gestational diabetes mellitus: Inhibin A (+) immunostain was observed in 2/4 cases in the intermediate trophoblast. Inhibin B (+) immunostain was observed in 2/4 cases in the syncytiotrophoblast. v) Placentas from gestations with fetal chromosome abnormalities: no Inhibin A immunoreaction was observed. Inhibin B (+) immunostain was observed in 13/14 cases in the syncytiotrophoblast and in 9/14 cases in the intermediate trophoblast. The cytotrophoblast, the umbilical cord, and the membranes do not participate in the production of Inhibins. DISCUSSION: Inhibin A and B are located in the syncytiotrophoblast and the intermediate trophoblast of the placenta, during early pregnancy (Inhibin A) and present throughout pregnancy (Inhibin B). No remarkable findings in placentas of pathological gestations support the evidence that Inhibins do not participate in processes that affect the development of the placenta or the fetus, but may participate in,the mechanism of labor.

The role of mini laparotomy in patients with uterine myomas.

AIM: The aim of this study was to evaluate the therapeutic effectiveness of myomectomy by mini laparotomy in patients with subserosal and/or intramural uterine myomas. MATERIALS AND METHODS: Between January 2002 and December 2008, 83 women with symptomatic uterine myomas were referred to the Second Department of Gynecology of St. Savvas Anticancer--Oncologic Hospital of Athens. The study included women with subserosal and/or intramural uterine myomas with a maximum diameter of ten cm. All patients underwent myomectomy by mini laparotomy. RESULTS: The median age of the patients was 36.8 years (range 19-43). The median number of the removed uterine myomas was 3.1 (range 1-12) and the median operative time was 98 minutes (range 47-170). All patients were mobilized within the first 24 hours and the median time of postoperative ileus was 1.6 days (range 1-3). The median hospital stay was 44 hours (range 30-120). There were no serious intraoperative or early postoperative complications. Conversion to laparotomy was performed only in four cases (4.82%), but none of the patients underwent emergency hysterectomy. During a mean follow up of 38 months, no recurrences of uterine myomas in the study population were observed. CONCLUSION: Mini laparotomic myomectomy is a safe and effective minimally invasive method alternative to laparoscopic myomectomy for patients with subserosal and/or intramural uterine myomas.

Surgical repair of a complicated urethro-vaginal fistula: case report and review of the literature.

BACKGROUND: Urethro-vaginal fistulae (UVF) occur usually as infrequent complications of a variety of gynecological surgical procedures. The aim of this study was to present an interesting case of a complicated UVF diagnosed after gynaecological surgery. CASE: A 61-year-old gravida-2, para-2, post-menopausal woman was referred with a complaint of urine loss through the vagina. She had undergone anterior and posterior vaginal wall repair due to cystocele and stress urinary incontinence (SUI). Transvaginal repair was performed 20 weeks after primary surgery. However, a second transvaginal reconstructive surgery using Martius-flap originating from the bulbocavernosus muscle was necessary due to persistent urine leakage in the vagina. Thirty-two months after successful urethro-vaginal treatment, the patient self-referred for persistent SUI. Burch colposuspension was performed and at 16 months follow-up the patient remains continent. DISCUSSION: Surgical repair of complicated UVF seems to be more successful with Martius flap interposition than with no interposition.

Successful management of evisceration occurred after exploratory laparotomy for bilateral ovarian micropapillary serous borderline tumors.

Micropapillary serous borderline tumor of the ovary is characterized by a more frequent association with extraovarian, especially invasive, implants. The aim of this study was to report the clinicopathological findings of a rare case of micropapillary serous borderline tumor of the ovary since there are less than 100 similar cases in the published literature. Additionally, the successful management of evisceration that complicated the postoperative stay of the patient is analyzed. The incidence of this severe complication is estimated between 0.29-2.3%. There are four main causes: suture tearing through the fascia, knot failure, suture failure, and extrusion of abdominal contents between sutures placed too far apart. At least 50% of the cases are due to technical error with a potentially lethal result.

Resistin in mid-trimester amniotic fluid in trisomy 21.

OBJECTIVE: The aim of this study was to examine whether resistin is present in second trimester amniotic fluid from trisomy 21 (also known as Down's syndrome) pregnancies and whether its concentration differs compared with euploid pregnancies. METHODS: The study cohort consisted of 58 women in the mid-trimester of pregnancy who underwent amniocentesis for prenatal diagnosis, 31 of whom carried a single fetus with diagnosed trisomy 21 (study group) and the rest with normal karyotype (control group, n = 27). Groups were matched for maternal and gestational age. Levels of resistin in amniotic fluid were measured by a commercially available enzyme-linked immunosorbent assay (ELISA) kit. RESULTS: Resistin was detected in all amniotic fluid samples. Its median concentration in the second trimester amniotic fluid of trisomy 21 pregnancies (2.1 ng/ml) was statistically significantly lower (p value <0.001) in comparison with that in euploid pregnancies (3.3 ng/ml). CONCLUSIONS: Resistin is a physiologic constituent of second trimester amniotic fluid. Lower levels of amniotic fluid resistin in pregnancies with trisomy 21 may reflect altered metabolic pathways in utero that could possibly be related with phenotypic features of the syndrome.

Uterine malignant mixed Müllerian tumor after adjuvant tamoxifen treatment for breast cancer.

BACKGROUND: Uterine malignant mixed Müllerian tumor (MMMT), also known as carcinosarcoma, is a biphasic tumor of the female genital tract and demonstrates both malignant epithelial (carcinoma) and mesenchymal (sarcoma) components. The authors present two cases of uterine MMMT after adjuvant tamoxifen (TAM) treatment for breast cancer and a review of the current literature. CASES: The patients presented with a complaint of abnormal uterine bleeding. They both had a history of breast cancer Stage IIB previously treated with modified radical mastectomy, at 51 and 78 months, respectively. They also had history of tamoxifen treatment 20 mg daily for seven and 73 months respectively. They underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy and total omentectomy. Histopathology revealed a uterine MMMT. Postoperatively, they received adjuvant chemotherapy and radiotherapy. One of the patients died 26 months after initial surgery due to uterine MMMT. CONCLUSION: Uterine MMMT is a rare, highly-aggressive, and rapidly-progressing tumor associated with a poor prognosis. Postmenopausal patients, with prolonged adjuvant TAM treatment for breast cancer, are at increased risk for the development of uterine MMMT.

Clinicopathological study of 112 cases of benign, pre-invasive and invasive lesions of the vagina: a 15-year review.

OBJECTIVE: Benign vaginal lesions are mainly asymptomatic and often diagnosed during routine screening gynecological examinations. Additionally, vaginal intraepithelial lesions are asymptomatic and diagnosis is often confirmed after vaginal biopsy under colposcopic evaluation in cases of abnormal cytological Papanicolaou examination or synchronous cervical intraepithelial neoplasia. On the other hand, primary vaginal cancer is rare representing approximately 1-2% of all gynecological cancers. Metastatic invasion of the vagina is common especially in cases of advanced stage cervical cancer. The aim of this study was to examine the diagnostic approach, the management strategy, and the pathological findings in cases of benign, pre-invasive and invasive vaginal lesions that were diagnosed and treated in our Department. MATERIALS AND METHODS: This was a 15-year retrospective study. Cases of benign, pre-invasive, and invasive vaginal lesions diagnosed during the last fifteen years at Aretaieion Hospital of the University of Athens, were analyzed. RESULTS: During this study period 40 cases of vaginal cysts (35.7% of all vaginal lesions) were diagnosed. Surgical excision of the lesions was decided in all cases and histology showed that the most frequent cyst type was mucus-secreting Mullerian (30%). During the study period, 23 cases of vaginal intraepithelial neoplasia (VAIN, 20.5% of all vaginal lesions) were detected. In 43.5% of the cases, histological diagnosis revealed low grade VAIN, while the remaining cases were classified as high grade VAIN. Furthermore, 11 cases of primary vaginal cancer (9.8% of all vaginal lesions) were diagnosed. The vast majority of them (91%) were squamous cell carcinomas. Additionally, histology confirmed the diagnosis of metastatic invasion of the vaginal wall in 38 cases (34% of all vaginal lesions). In the majority of these cases (55.2%), primary cancer was located in the cervix. DISCUSSION: Benign, pre-invasive and invasive vaginal lesions are relatively uncommon and usually accompany lesions in other sites of the lower genital tract. Their diagnosis is based on gynecological or colposcopical examination. Treatment depends on the type of the lesion and the progression of the disease.

Comparing transvaginally defined endometrial thickness with hysteroscopic and histopathologic findings in asyptomatic postmenopausal women.

PURPOSE: To assess the diagnostic value of transvaginal sonography (TVS) measurement of the endometrium compared to hysteroscopic findings and histopathologic reports in order to facilitate clinical management in asymptomatic postmenopausal women with thickened endometrium. METHODS: During the period between January 2000 and December 2008, a retrospective analysis was performed including cases of women who were preoperatively diagnosed with a sonographically thickened endometrium, while asymptomatic, and therefore underwent hysteroscopic and fractionated dilatation and curettage (D & C) under general anesthesia at the Second Department of Obstetrics and Gynecology at Aretaieion Hospital in Athens, Greece. In the present study we compare US, hysteroscopic and pathologic findings. RESULTS: The mean age of the patients ranged between 54-74 years (mean age 65.2 +/- 6.8 years). In 108 cases, sonographically measured endometrial thickness ranged between 5 and 10 mm. In 59 cases, endometrial thickness ranged between 11 and 15 mm, whereas in 22 cases, between 16 and 20 mm and finally, in 13 cases endometrial thickness was more than 20 mm. Hysteroscopic examination revealed endometrial polyps in 161 cases, focal hyperplastic lesions in 28 cases, complete hyperplastic lesions in five cases while atrophy was found in five and cancer in three cases, respectively. Pathological results of the samples taken after hysteroscopy are as follows: in 169 cases (83.67%) in women with asymptomatic abnormal endometrial thickness, an endometrial polyp was present. Endometrial thickness in these cases patients was 10.9 +/- 7.5 mm. In patients with focal hyperplasia (22 cases), endometrial thickness was 7.2 +/- 0.5 mm but in patients with complete hyperplasia (5 cases) endometrial thickness was higher (12.3 +/- 5.1 mm). Finally, in three cases with endometrial carcinoma endometrial thickness was 15.5 +/- 7.8 mm. Six cases out of 28 described in our study were diagnosed as focal hyperplasia and two out of five cases as complete hyperplasia, whereas histological reports classified these cases as endometrial polyps. The other histological diagnoses confirmed hysteroscopic findings and thus provided the same results. CONCLUSIONS: We recommend hysteroscopy to follow gynecological TVS when a thickened endometrium is found in asyptomatic postmenopausal women for better diagnostic and, in a later stage, therapeutic efficacy.

Endometrial stromal sarcoma in a 29-year-old patient. Case report and review of the literature.

OBJECTIVE: Endometrial stromal sarcomas are rare tumors accounting for about 0.2% of all genital tract malignancies. They are considered to occur more often in premenopausal women. Endometrial stromal sarcomas are hormone sensitive tumors. A state of hyper-estrogenemia could act as a growth stimulus. Given the rarity of these tumors there are limited reports in the literature referring to the clinical management and final outcome of these cases. CASE: The patient, a 29-year-old woman, had a surgical history of myomectomy in another hospital three months before her referal to our department. The histological examination of the removed myoma showed an endometrial stromal sarcoma. Total abdominal hysterectomy, with bilateral salpingo-oophorectomy, omentectomy and elective pelvic lymphadenectomy were then performed as a second radical surgical approach. CONCLUSION: Endometrial stromal sarcomas are uncommon and their differential diagnosis from typical submucosal uterine myomas or benign endometrial polyps could be difficult. The hysteroscopic features of uterine sarcomas are often similar to those of endometrial polyps or submucosal myomas. The histological examination of the specimen is necessary to exclude malignancy and establish the final diagnosis. Total abdominal hysterectomy, bilateral salpingo-oopherectomy with pelvic lymphadenectomy is the optimal treatment in cases of endometrial stromal sarcomas.

Primary ovarian leiomyosarcoma.

BACKGROUND: Primary ovarian leiomyosarcoma is an extremely rare subtype of ovarian sarcomas. It most commonly occurs in postmenopausal women and has unfavorable prognosis. CASE: The patient, a 58-year-old postmenopausal woman, presented with a complaint of abdominal pain. Preoperative examination revealed an intraabdominal mass 25 x 17 x 14 cm in the right adnexa. She underwent bilateral salpingo-oophorectomy, total omentectomy, appendectomy and bilateral pelvic lymphadenectomy. The histopathology revealed leiomyosarcoma of the right ovary Stage Ia. She did not receive any postoperative adjuvant therapy. Follow-up 21 months after initial surgery, showed no evidence of recurrence. CONCLUSION: Additional studies are needed to understand more about the nature, clinical behavior and treatment of this very rare tumor.

Clinicopathological changes of uterine leiomyomas after GnRH agonist therapy.

OBJECTIVE: Gonadotrophin-releasing hormone agonist (GnRHa) has been commonly used for the medical treatment of prostate cancer, precocious puberty, endometriosis, adenomyosis and uterine leiomyomas. GnRHa therapy in cases of symptomatic uterine leiomyomas aims for the reduction of their size and remission of symptoms such as menometrorrhagia, causing a state of hypoestrogenemia. This is considered to be a helpful preoperative strategy in cases of large myomas, or anemia because of abnormal vaginal bleeding. The aim of this retrospective study was to examine the clinicopathological changes in uterine leiomyomas exposed to preoperative GnRHa therapy for two up to six months. MATERIALS AND METHODS: The study group consisted of 10 premenopausal patients who were treated with GnRHa prior to surgery. RESULTS: In all cases the size of leiomyomas was reduced after GnRHa therapy. A microscopic review of the surgical specimens showed increased cellularity and ischemic type of necrosis. CONCLUSION: Morphological changes of uterine leiomyomas are often associated with preoperative GnRH agonist therapy. The differential diagnosis from uterine leiomyosarcomas includes absence of mitotic activity.

Removal of a large bizarre uterine leiomyoma by operative hysteroscopy. Case report and review of the literature.

BACKGROUND: Atypical leiomyomas are relatively uncommon in the general practice of gynaecology. We present a case of a large uterine bizarre leiomyoma removed by operative hysteroscopy and review of the literature. CASE: The patient, a 49-year-old, gravida 3, para 3, perimenopausal Greek woman presented to our Department because of dysmenorrhea and abnormal vaginal bleeding. She underwent hysteroscopy in which a large submucosal leiomyoma was detected and entirely removed in one session. The histopathology revealed bizarre uterine leiomyoma. DISCUSSION: There is no evidence to indicate that hysterectomy is necessary, if the diagnosis of atypical leiomyoma has been firmly established.

Antibiotic prophylaxis in diagnostic hysteroscopy: is it necessary or not?

OBJECTIVE: Surgical site infection remains the most common complication of surgery. Up to 5% of patients undergoing operative procedures will develop an infection leading to a prolonged hospital stay with increased cost. On the other hand the indiscriminate use of antibiotics has been associated with the development of antibiotic-resistant bacteria. The aim of this study was to examine the effect of antibiotic prophylaxis in cases of diagnostic hysteroscopy. STUDY DESIGN: This was an eight-year randomized controlled clinical trial. The study group consisted of 364 women who underwent diagnostic hysteroscopy because of menometrorrhagia, post-menopausal vaginal bleeding, ultrasound findings of increased thickness of the endometrium, or as a routine examination prior to a first in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatment. RESULTS: Of the 364 women who underwent diagnostic hysteroscopy during this eight-year study period, 176 received antibiotic prophylaxis whereas 188 did not. There were no significant differences in the prevalence of postoperative infections observed between women who received antibiotic prophylaxis (0.57%) and those who underwent the procedure without prophylaxis (0.53%). CONCLUSION: Given the very low risk of infection after diagnostic hysteroscopy and lack of evidence of efficacy, routine antibiotic prophylaxis is not recommended.
