Especificidades técnicas no tamponamento uterino com balões e algumas dificuldades técnicas / Technical specificities in uterine tamponade with balloons and some technical difficulties

A mortalidade materna é inaceitavelmente alta. A hemorragia pós-parto encontra- se na primeira posição no mundo, tendo como principal causa específica a atonia uterina. Eventualmente, as medidas iniciais e a terapia farmacológica não são efetivas no controle do sangramento, impondo a necessidade de tratamentos invasivos, cirúrgicos ou não. Entre esses, o tamponamento uterino com balão requer recursos locais mínimos e não exige treinamento extensivo ou equipamento muito complexo. Entretanto, algumas dificuldades podem ocorrer durante a inserção, infusão ou manutenção do balão na cavidade uterina, com especificidades relacionadas à via de parto. Após o parto vaginal, a dificuldade mais prevalente é o prolapso vaginal do balão. Na cesárea, as principais dificuldades são a inserção e o posicionamento do balão na cavidade uterina, principalmente nas cesáreas eletivas. Este artigo revisa e ilustra as principais dificuldades e especificidades relacionadas ao tamponamento uterino com balões.

Maternal mortality is unacceptably high. Postpartum hemorrhage is ranked first in the world, with the main specific cause being uterine atony. Eventually, initial measures and pharmacological therapy are not effective in controlling bleeding, imposing the need for invasive treatments, surgical or not. Among these, uterine balloon tamponade requires minimal local resources and does not require extensive training or very complex equipment. However, some difficulties may occur during insertion, infusion, or maintenance of the balloon in the uterine cavity, with specificities related to the mode of delivery. After vaginal delivery, the most prevalent difficulty is vaginal balloon prolapse. In cesarean section, the main difficulty is the insertion and positioning of the balloon in the uterine cavity, especially in elective cesarean sections. This article reviews and illustrates the main difficulties and specificities related to uterine balloon tamponade.

The Management of a patient with a fragmented intrauterine device embedded within the cervical canal.

A 28-year-old woman presented with a malpositioned intrauterine device (IUD) that was fragmented and significantly entrenched within the cervical canal and myometrium. IUD malposition with concomitant device fragmentation and embedded segments, albeit rare, should be a consideration given the device's prevalence.

Quality of tissue from punch biopsy forceps vs. round loop electrode in colposcopically directed biopsy: a randomized controlled trial.

OBJECTIVE: To compare the quality of tissue from punch biopsy forceps (PB group) with round loop electrode (LE group) in colposcopically directed biopsy along with the evaluation of pain associated with each procedure. METHODS: Patients with abnormal cervical cytologic results and abnormal colposcopic findings were enrolled into a randomized trial into either a PB group or LE group. The quality of tissue was evaluated in regards to the size of tissue, site of tissue, and tissue damage. Each quality had 1 to 3 points and the sum of each quality contributed to the total tissue score that ranged from 3 to 9. Pain associated with each procedure was assessed by a visual analog scale (VAS). This was a clinical trial study and was registered at www.clinicaltrials.in.th (Identifier: TCTR20160404001). RESULTS: Ninety-six women who met all eligibility requirements were enrolled in the study. Forty-eight patients were randomly assigned to the PB group and 48 patients were randomized into the LE group. The characteristics of the patients were similar between the 2 groups with the exception of the median age. The median total tissue score was 8 points in the LE group which was more than the median of 7 points in the PB group with a statistically significant difference (p=0.014). However, the median VAS pain score in both groups was 3.4 (p=0.82). CONCLUSION: The quality of cervical tissues obtained from biopsy with a round loop electrode was better than the punch biopsy forceps with no difference in the level of pain.

About a case of traumatic separation of the cervix from the uterine corpus, diagnosed in a context of infertility.

This article reports a case of cervico-isthmic disjunction unnoticed during childhood, diagnosed in a context of primary infertility and endometriosis, and surgically treated. It is an uncommon condition. The diagnosis is most often made as part of an assessment of primary amenorrhea in a young woman with a history of severe pelvic trauma. It is suspected after imaging assessment and confirmed intraoperatively. The treatment consists in an anastomosis between the cervix and the uterine body, after individualizing these two structures, around a drain guiding healing. After this surgery, multiple pregnancies have been successfully carried out.

Risk factors for trachelectomy following supracervical hysterectomy.

INTRODUCTION: We identified risk factors for trachelectomy after supracervical hysterectomy (SCH) due to persistence of symptoms. MATERIAL AND METHODS: A retrospective case-control study in a university-affiliated hospital. Seventeen women who underwent a trachelectomy following SCH for nonmalignant indications between June 2002 and October 2014 were compared with 68 randomly selected women (controls) who underwent a SCH within the same time period. Demographics and clinical characteristics were compared between the study and control groups. Univariate analysis identified potential risk factors for trachelectomy following SCH. Univariate logistic regression models predicted which patients would have a trachelectomy following SCH. RESULTS: The occurrence of trachelectomy following SCH during the study period was 0.9% (17/1892). The study group was younger than the control group (mean age 38 ± 6 years vs. 44 ± 5 years; p < 0.001). Patients who had a history of endometriosis [odds ratio (OR) 6.23, 95% CI 1.11-40.5, p = 0.038] had increased risk for trachelectomy. Pathology diagnosed endometriosis only among women in the study group. Preoperative diagnosis of abnormal uterine bleeding (OR 0.22, 95% CI 0.06-0.075, p = 0.016), anemia (OR 0.12, 95% CI 0.01-0.53; p = 0.003), and fibroid uterus (OR 0.24, 95% CI 0.07-0.82, p = 0.024) reduced the risk for future trachelectomy. CONCLUSION: Young age and endometriosis are significant risk factors for trachelectomy following SCH.

Endometrial Adenocarcinoma Presenting as Hematometra with Underlying Thickened Endometrial Lining in a Postmenopausal Woman - A Case Report.

BACKGROUND: Although most postmenopausal women diagnosed with endometrial cancer usually present with vaginal bleeding, when complete cervical stenosis is present, this sign may be missing. In these cases, the patient usually complaints for pelvic or abdominal pain while the transvaginal ultrasonography might reveal the presence of an intrauterine fluid collection in association with a thickened endometrial lining. CASE REPORT: We present the case of a 65-year-old patient who presented with association of pelvic pain, enlarged uterine cavity with an underlying hematometra and an irregular, thickened endometrium who was submitted to surgery for total histerectomy, bilateral adnexectomy, pelvic and para-aortic lymph node dissection. CONCLUSION: Histopathological studies revealed the presence of a well-differentiated endometrial adenocarcinoma. At three years of follow-up, the patient is free of any recurrent disease.

Use of Oral Misoprostol for Cervical Priming before Hysteroscopy: A Randomized Comparison of Two Dosages.

OBJECTIVE: The study aims to compare the safety and effectiveness of 200 and 400 µg of oral misoprostol for cervical priming before hysteroscopy. METHODS: A double-blinded randomized study included 70 patients scheduled for hysteroscopy in a Lebanese University Hospital. Two dosages of oral misoprostol (200 or 400 µg) were randomly distributed to these patients 1 h before surgery under general anesthesia. Subjective assessment of the ease of dilatation, size of the first used Hegar, cervical injuries, bleeding or uterine perforation, duration of the procedure and misoprostol adverse effect were all noted and compared. RESULTS: The difficulty of dilation until a Hegar 10 was similar for both treatment groups. Operative time was not reduced with a higher misoprostol dosage. We found 2 uterine perforations within the 200 µg group (6.7%), and none within the 400 µg group. Cervical lacerations and bleeding were similar (20%) for both treatment groups. A 2-fold increase in side effects (nausea, vomiting and cramps) is reported among the 400 µg group. CONCLUSIONS: Increasing the dose of misoprostol from 200 to 400 mg doubled the rate of side effects while no clinical benefit was noted. Larger trials are needed to assess rates of uterine perforation with the 200 µg dosage.

A postpartum haemorrhage package with condom uterine balloon tamponade: a prospective multi-centre case series in Kenya, Sierra Leone, Senegal, and Nepal.

OBJECTIVE: To evaluate the effectiveness and safety of an ultra-low-cost uterine balloon tamponade package (ESM-UBT™) for facility-based management of uncontrolled postpartum haemorrhage (PPH) in Kenya, Sierra Leone, Senegal, and Nepal. DESIGN: Prospective multi-centre case series. SETTING: Facilities in resource-scarce areas of Kenya, Sierra Leone, Nepal, and Senegal. POPULATION: Women with uncontrolled postpartum haemorrhage in 307 facilities across the four countries. METHODS: A standardised ESM-UBT package was implemented in 307 facilities over 29 months (1 September 2012 to 1 February 2015). Data were collected via a multi-pronged approach including data card completion, chart reviews, and provider interviews. Beginning in August 2014, women who had previously undergone UBT placement were sought and queried regarding potential complications associated with UBT use. MAIN OUTCOME MEASURES: All-cause survival, survival from PPH, and post-UBT use complications (surgery, hospitalisation, antibiotics for pelvic infection) associated with UBT use. RESULTS: 201 UBTs were placed for uncontrolled vaginal haemorrhage refractory to all other interventions. In all, 38% (71/188) of women were either unconscious or confused at the time of UBT insertion. All-cause survival was 95% (190/201). However, 98% (160/163) of women survived uncontrolled PPH if delivery occurred at an ESM-UBT online facility. One (1/151) potential UBT-associated complication (postpartum endometritis) was identified and two improvised UBTs were placed in women with a ruptured uterus. CONCLUSIONS: These pilot data suggest that the ESM-UBT package is a clinically promising and safe method to arrest uncontrolled postpartum haemorrhage and save women's lives. The UBT was successfully placed by all levels of facility-based providers. Future studies are needed to further evaluate the effectiveness of ESM-UBT in low-resource settings. TWEETABLE ABSTRACT: Evidence for ESM-UBT as a clinically promising and safe method to arrest uncontrolled PPH and save women's lives.

Complications of Hysteroscopic and Uterine Resectoscopic Surgery.

Adverse events associated with hysteroscopic procedures are generally rare, but, with increasing operative complexity, it is now apparent that they are experienced more often. There exists a spectrum of complications that relate to generic components of procedures, such as patient positioning, anesthesia, and analgesia, to a number that are specific to intraluminal endoscopic surgery that largely comprise perforation and injuries to surrounding structures and blood vessels. Whereas a number of endoscopic procedures require the use of distending media, the response of premenopausal women to excessive absorption of nonionic fluids used for hysteroscopy is somewhat unique, and deserves special attention on the part the surgeon. There is also an increasing awareness of uncommon but problematic sequelae related to the use of monopolar radiofrequency uterine resectoscopes that involve thermal injury to the vulva and vagina. Furthermore, the uterus that has previously undergone hysteroscopic surgery may behave in unusual ways, at least in premenopausal women who experience menstruation or who become pregnant. Fortunately, better understanding of the mechanisms involved in these adverse events, as well as the use or development of a number of innovative devices, have collectively provided the opportunity to perform hysteroscopic and resectoscopic surgery in a manner that minimizes risk to the patient.

Postpartum cervical repair in mice: a morphological characterization and potential role for angiogenic factors.

The cervix undergoes marked mechanical trauma during delivery of the baby at birth. As such, a timely and complete tissue repair postpartum is necessary to prevent obstetrical complications, such as cervicitis, ectropion, hemorrhage, repeated miscarriages or abortions and possibly preterm labor and malignancies. However, our knowledge of normal cervical repair is currently incomplete and factors that influence repair are unclear. Here, we characterize the morphological and angiogenic profile of postpartum repair in mice cervix during the first 48 h of postpartum. The key findings presented here are: (1) cervical epithelial folds and size are diminished during the first 48 h of postpartum repair, (2) hypoxic inducible factor 1a, vascular endothelial growth factor (VEGF), and VEGF receptor 1 expression are pronounced early in postpartum cervical repair, and (3) VEGF receptor 2 gene and protein expressions are variable. We conclude that postpartum cervical repair involves gross and microscopic changes and is linked to expression of angiogenic factors. Future studies will assess the suitability of these factors, identified in the present study, as potential markers for determining the phase of postpartum cervical repair in obstetrical complications, such as cervical lacerations.

Preoperative ripening of the cervix before operative hysteroscopy.

BACKGROUND: Hysteroscopy is an operation in which the gynaecologist examines the uterine cavity using a small telescopic instrument (hysteroscope) inserted via the vagina and the cervix. Almost 50% of hysteroscopic complications are related to difficulty with cervical entry. Potential complications include cervical tears, creation of a false passage, perforation, bleeding, or simply difficulty in entering the internal os (between the cervix and the uterus) with the hysteroscope. These complications may possibly be reduced with adequate preparation of the cervix (cervical ripening) prior to hysteroscopy. Cervical ripening agents include oral or vaginal prostaglandin, which can be synthetic (e.g misoprostol) or natural (e.g. dinoprostone) and vaginal osmotic dilators, which can be naturally occurring (e.g. laminaria) or synthetic. OBJECTIVES: To determine whether preoperative cervical preparation facilitates cervical dilatation and reduces the complications of operative hysteroscopy in women undergoing the procedure for any condition. SEARCH METHODS: In August 2014 we searched sources including the Menstrual Disorders and Subfertility Group (MDSG) Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsycINFO, CINAHL, ClinicalTrials.gov and reference lists of relevant articles. We searched for published and unpublished studies in any language. SELECTION CRITERIA: Two review authors independently selected randomised controlled trials (RCTs) of cervical ripening agents used before operative hysteroscopy in pre- and postmenopausal women. Cervical ripening agents could be compared to each other, placebo or no treatment. DATA COLLECTION AND ANALYSIS: Data extraction and quality assessment were conducted independently by two review authors. The primary review outcomes were effectiveness of cervical dilatation (defined as the proportion of women requiring mechanical cervical dilatation) and intraoperative complications. Secondary outcomes were mean time required to dilate the cervix, preoperative pain, cervical width, abandonment of the procedure, side effects of dilating agents and duration of surgery. We calculated odds ratios (ORs) for dichotomous outcomes and mean differences (MDs) for continuous outcomes, with 95% confidence intervals ( CIs). Data were statistically pooled where appropriate. Heterogeneity was assessed using the I(2) statistic. The overall quality of the evidence was assessed using GRADE methods. MAIN RESULTS: Nineteen RCTs with a total of 1870 participants were included. They compared misoprostol with no treatment or placebo, dinoprostone or osmotic dilators.Misoprostol was more effective for cervical dilatation than placebo or no intervention, with fewer women requiring mechanical dilatation (OR 0.08, 95% CI 0.04 to 0.16, five RCTs, 441 participants, I(2)=0%, moderate quality evidence). This suggests that in a population in which 80% of women undergoing hysteroscopy require mechanical dilatation without use of preoperative ripening agents, use of misoprostol will reduce the need for mechanical dilatation to between 14% and 39%. Misoprostol was associated with fewer intraoperative complications (OR 0.37, 95% CI 0.18 to 0.77, 12 RCTs, 901 participants, I(2)=0%, moderate quality evidence). This suggests that in a population in which 3% of women undergoing hysteroscopy experience intraoperative complications without use of preoperative ripening agents, use of misoprostol will reduce the risk of complications to 2% or less.When specific complications were considered, the misoprostol group had a lower rate of cervical laceration or tearing (OR 0.25, 95% CI 0.11 to 0.57, nine RCTS, 669 women, I(2)=0%, moderate quality evidence) or false track formation (OR 0.34, 95% CI 0.12 to 0.97, seven RCTs, 560 participants, I(2)=0%, moderate quality evidence). There was no evidence of a difference between the groups in rates of uterine perforation (0.42, 95% CI 0.13 to 1.38, seven RCTs, 455 participants, I(2)=0%, low quality evidence) or uterine bleeding (OR 0.51, 95% CI 0.10 to 2.49, four RCTs, 340 participants, I(2)=0%, low quality evidence). Some treatment side effects (mild abdominal pain, vaginal bleeding, and increased body temperature) were more common in the misoprostol group.Compared with dinoprostone, misoprostol was associated with more effective cervical dilatation, with fewer women requiring mechanical dilatation (OR 0.58; 95% CI 0.34 to 0.98; one RCT, 310 participants, low quality evidence) and with fewer intraoperative complications (OR 0.32; 95% CI 0.12 to 0.83, one RCT, 310 participants, low quality evidence). However treatment side effects were more common in the misoprostol arm.Compared to osmotic dilatation (laminaria), misoprostol was associated with less effective cervical dilatation, with more women in the misoprostol group requiring mechanical dilatation (OR 5.96, 95% CI 2.61 to 13.59, one RCT, 110 participants, low quality evidence). There was no evidence of a difference between misoprostol and osmotic dilators in intraoperative complication rates (OR 5.14, 95% CI 0.24 to 109.01, three RCTs, 354 participants, low quality evidence), with only two events reported altogether.The overall quality of the evidence ranged from low to moderate. The main limitations in the evidence were imprecision and poor reporting of study methods. AUTHORS' CONCLUSIONS: There is moderate quality evidence that use of misoprostol for preoperative ripening of the cervix before operative hysteroscopy is more effective than placebo or no treatment and is associated with fewer intraoperative complications such as lacerations and false tracks. However misoprostol is associated with more side effects, including preoperative pain and vaginal bleeding. There is low quality evidence to suggest that misoprostol has fewer intraoperative complications and is more effective than dinoprostone.There is also low quality evidence to suggest that laminaria may be more effective than misoprostol, with uncertain effects for complication rates. However the possible benefits of laminaria need to be weighed against the inconvenience of its insertion and retention for one to two days.

Estrogen treatment of acetic acid burns to the vagina, cervix, and perineum: a case report and review of the literature.

In colposcopic evaluation of the cervix, acetic acid of 3 to 5% is commonly used for identification of preneoplastic and neoplastic cells. Acetic acid is a known caustic substance and has the potential to cause irritation and chemical burns when there is sufficient concentration or duration of contact. The authors present a unique case of a woman who inadvertently received undiluted acetic acid during a routine colposcopy, resulting in significant chemical burns of the vagina, cervix, and perineum. Her burns were treated with topical estrogen cream of 1 g twice daily applied directly to the wounds. The burn wounds were fully healed within 8 weeks without complication or additional treatment. At 6 months after the injury, the patient was allowed to engage in sexual activity, and vaginal dilation and pelvic floor therapy were initiated. At 12 months postinjury, her only symptomatic scarring at the left vaginal wall continues to improve. Thus, topical estrogen treatment of 1 g applied twice daily should be continued until burn scar maturation is complete and treatment improvement plateaus in cases of burns to the vagina, cervix, and perineum. This case is further clinical evidence of estrogen's positive effect on wound healing and its potential role in burn treatment.

Amniotic fluid embolism induces uterine anaphylaxis and atony following cervical laceration.

Amniotic fluid embolism (AFE) is a rare, high-risk obstetric complication primarily found in the lungs and potentially related to anaphylaxis. Tryptase release from the mast cell reflects anaphylaxis. Case report and findings: A female, aged over 40 years, presented with uterine atony and lethal hemorrhage after induced vaginal labor. Cervical laceration was accompanied by severe hemorrhage. Stromal edema and myometrial swelling were consistent with uterine atony. Alcian blue staining and zinc coproporphyrin immunostaining disclosed AFE, which was more prominent in the uterus than in the lungs. Tryptase immunostaining was diffuse and prominent around the activated mast cells (halos) in the uterus, including the cervix. Similar distribution of findings on the AFE markers, tryptase halos, complement receptor C5aR, and atony in the uterus suggested the causality of AFE to anaphylaxis, complement activation and atony. It is probable that disseminated intravascular coagulation (DIC), induced by AFE, uterine atony and cervical laceration, caused the lethal hemorrhage. It is likely that AFE, in association with cervical laceration, induces uterine anaphylaxis, complement activation, atony, DIC and lethal hemorrhage.
