Clinical Diagnosis and Early Medical Management for Endometriosis: Consensus from Asian Expert Group.

This work provides consensus guidance regarding clinical diagnosis and early medical management of endometriosis within Asia. Clinicians with expertise in endometriosis critically evaluated available evidence on clinical diagnosis and early medical management and their applicability to current clinical practices. Clinical diagnosis should focus on symptom recognition, which can be presumed to be endometriosis without laparoscopic confirmation. Transvaginal sonography can be appropriate for diagnosing pelvic endometriosis in select patients. For early empiric treatment, management of women with clinical presentation suggestive of endometriosis should be individualized and consider presentation and therapeutic need. Medical treatment is recommended to reduce endometriosis-associated pelvic pain for patients with no immediate pregnancy desires. Hormonal treatment can be considered for pelvic pain with a clinical endometriosis diagnosis; progestins are a first-line management option for early medical treatment, with oral progestin-based therapies generally a better option compared with combined oral contraceptives because of their safety profile. Dienogest can be used long-term if needed and a larger evidence base supports dienogest use compared with gonadotropin-releasing hormone agonists (GnRHa) as first-line medical therapy. GnRHa may be considered for first-line therapy in some specific situations or as short-term therapy before dienogest and non-steroidal anti-inflammatory drugs as add-on therapy for endometriosis-associated pelvic pain.

Venous Thromboembolism and Adenomyosis: A Retrospective Review.

OBJECTIVES: The objective of the study was to evaluate the incidence of venous thromboembolism (VTE) in patients who have been admitted for adenomyosis at our institute and describe their clinical characteristics and management. MATERIALS AND METHODS: A retrospective review of the medical records of all patients who were admitted to the gynecology ward between January 2015 and August 2016 was conducted, and all patients who had adenomyosis were included in this study. Clinical details that were evaluated included age, parity, body mass index, significant comorbidities, size of the uterus on physical examination, the size of the adenomyoma (if present) on pelvic ultrasonography, initial hemoglobin, and hematocrit on admission, whether blood transfusion was required, acute and long-term treatment and whether or not there were any associated VTE and treatment given. RESULTS: Forty-one patients were included in this study. Five (12.2%) out of the 41 patients had associated VTE; all five had pulmonary embolism (PE), while two also had a concurrent left lower limb deep-vein thrombosis. Three out of the five patients had worsening menorrhagia following anticoagulation, which gonadotropin-releasing hormone analogs were effective in controlling. Four of the five patients eventually underwent a hysterectomy for long-term management of adenomyosis. CONCLUSION: This case series describes a few clinical cases where VTE (particularly PE) has been observed with adenomyosis, the challenges in managing these patients, and effective treatment approaches.

Tubo-Ovarian Abscesses: Epidemiology and Predictors for Failed Response to Medical Management in an Asian Population.

Pelvic inflammatory disease (PID) complicated by tubo-ovarian abscesses (TOA) has long-term sequelae in women of reproductive age. Consensus on the optimal treatment of TOA remains lacking. Most clinicians utilize antibiotics as a first-line conservative approach, failing which invasive intervention is adopted. Our aim is to identify risk factors predicting failed response to conservative medical management for TOA in an Asian population. A retrospective cohort study of 136 patients admitted to a tertiary hospital in Singapore for TOA between July 2013 and December 2017 was performed. Patients were classified into 2 groups: successful medical treatment with intravenous antibiotics and failed medical treatment requiring invasive intervention. 111 (81.6%) of patients were successfully treated with conservative medical approach using intravenous antibiotics; 25 (18.4%) required invasive intervention having failed medical therapy. Multivariate logistic regression model adjusted for age, ethnicity, C-reactive Protein (CRP), TOA size, and body mass index (BMI) showed the odds ratio (OR) of each centimetre increase in TOA size to be 1.28 (95% confidence interval (CI) 1.03-1.61; P=0.030) and every kg/m2 increase in BMI to be 1.10 (95% CI 1.00-1.21; P=0.040). Failed medical management was predicted by a cutoff of TOA size ≥ 7.4 cm and ≥ BMI 24.9 kg/m2. Patients who failed medical treatment received a mean of 4.0±2.1 days of antibiotics before a decision for invasive intervention was made, with a significantly longer intravenous antibiotic duration (9.4±4.3 versus 3.6±2.2 days; P <0.001) and prolonged hospitalization (10.8± 3.6 versus 4.5 ± 2.0 days; P <0.001) compared to the medical group. Patients with higher BMI and larger TOA size were associated with failed response to conservative medical management in our study population. Early identification of these patients for failed medical therapy is imperative for timely invasive intervention to avoid prolonged hospitalization, antibiotic usage, and patient morbidity.

The clinical profile of young and adolescent women with laparoscopically diagnosed endometriosis in a Singapore tertiary hospital.

OBJECTIVE: Endometriosis has been increasingly recognized as the cause of severe dysmenorrhea among younger women including adolescents, often with significant delay from time of presentation to diagnosis. Data on the South East Asian women is scarce. This study aims to describe the disease pattern in a group of young Asian women with histological diagnosis of endometriosis in our center. MATERIALS AND METHODS: A total of 709 laparoscopic operations were performed for endometriosis in our center between 2000 and 2007. Women aged 25 years old and below were included in this study. Details regarding clinical presentation and severity of disease were retrospectively reviewed and described. RESULTS: A total of 45 women were included in this study, aged between 14 years and 25 years. Thirty seven patients (82.3%) were aged between 21 years and 25 years. Racial distribution was as follows: 57.8% Chinese, 26.7% Malay, and 15.6% Indian. Dysmenorrhea was the commonest symptom (84.4%); 44.4% of which were described as mild. Eleven patients (24.4%) presented with severe symptoms resulting in absence from school or work. Severity of endometriosis during laparoscopy was staged using the rAFS staging system, and was 11.1%, 17.8%, 28.9%, and 42.2% for disease Stage I, Stage II, Stage III, and Stage IV, respectively. CONCLUSION: Endometriosis can cause severe disease even in adolescents and young females. Increased awareness among patients and healthcare providers would raise a higher index of suspicion for endometriosis in these women, with consequent early treatment which may result in better functional and fertility outcomes.

Laparoscopic Anterior Resection with Transvaginal Specimen Extraction (TVSE) for Colorectal Cancer and Concomitant Total Hysterectomy and Bilateral Salpingo-Oophrectomy (THBSO): A Technical Description.

BACKGROUND: Natural orifice specimen extraction (NOSE) has evolved to circumvent the need for a specimen extraction site. Transvaginal specimen extraction (TVSE) for colorectal disease has been shown to be safe and feasible in selected cases.1 , 2 We describe our technique of TVSE in a case of laparoscopic ultra-low anterior resection (ULAR) with defunctioning ileostomy (DI) with a concomitant total hysterectomy and bilateral salpingo-oophrectomy (THBSO). METHODS AND RESULTS: A 74-year-old Chinese female was diagnosed with a mid-rectal cancer following colonoscopic evaluation for a change in bowel habits. Preoperative magnetic resonance imaging (MRI) suggested T2N0 disease and the patient was recommended for upfront surgery following multidisciplinary discussion. Computed tomography (CT) scan confirmed a 4.3 × 3.4 cm right adnexal cystic lesion, without enhancing septations or soft tissue component. No metastatic disease was identified. The patient underwent a laparoscopic ULAR with DI and THBSO with TVSE; operative time was 469 min. The specimen showed a 2.5 cm mid-rectal tumour. Histology revealed a pT3N1a moderately differentiated adenocarcinoma of the mid rectum, with 1 of 20 lymph nodes involved by metastatic carcinoma. The quality of the total mesorectal excision (TME) was good, with no breach in the mesorectal fascia. The distal and radial margins were 1.5 and 3.0 cm, respectively. The patient recovered well postoperatively, with minimal wound site pain, and was discharged well on postoperative day 5. CONCLUSION: TVSE is oncologically safe and feasible in certain malignant colorectal pathologies. It is an option to consider in selected cases that require a concomitant gynecological procedure.

First ever case of spontaneous triplet cornual pregnancy: management of laparoscopic cornual resection with modified endoloop method.

A 23-year-old woman, gravida 2 para 0, presented at 8 weeks gestation with a spontaneously conceived triplet cornual ectopic pregnancy. She was at high risk of ectopic pregnancy as she had been previously treated for pelvic inflammatory disease and had also undergone laparoscopic salpingostomy for right-sided ectopic pregnancy. She was clinically stable and her abdomen was soft and non-tender. The diagnosis was made on transvaginal ultrasound scan and this was confirmed on the three-dimensional scan. She was counselled about her treatment options and subsequently underwent laparoscopic cornual resection using the modified endoloop method. The estimated blood loss was 20 ml intraoperatively and the patient recovered well. She subsequently conceived spontaneously with an intrauterine pregnancy and underwent lower segment caesarean section at 37 weeks in view of previous laparoscopic cornual resection. Intraoperatively, the right cornua appeared normal and there was no sign of thinning.

Use of narrowband imaging for the detection of endometriosis.

STUDY OBJECTIVE: To show a new technique using narrowband imaging for the detection of endometriosis. DESIGN: A step-by-step illustration of the difference in visualization of endometriosis using a visible light spectrum laparoscope compared with a narrowband imaging light source. SETTING: Radical excision of endometriosis is considered the best treatment to control the disease extent and symptoms of endometriosis. Therefore, it is imperative that all endometriotic lesions are recognized and identified in order to thoroughly remove them. A narrowband imaging system enhances the visualization of capillary vessels and microstructures containing blood hemoglobin on the mucosal surface. It makes use of 415- and 540-nm filters that are strongly absorbed by blood hemoglobin. In this manner, microvessels, which are not clearly seen by conventional light, are enhanced. With the inherent neovascularization noted in endometriosis, endometriotic lesions may be more recognizable. Clear vesicular lesions of endometriosis are glandular excrescences, which are early signs of recurrent inflammation from endometriosis with accompanying angiogenesis. These are more pronounced under narrowband imaging. INTERVENTIONS: The use of the visible light spectrum contrasted with narrowband imaging that changes the normal color contrasts of the endoscopic image in the different areas of the pelvic cavity. MEASUREMENTS AND MAIN RESULTS: Narrowband imaging is helpful as an additional modality for the identification of endometriosis. In particular, clear vesicular lesions of endometriosis, which are not as evident under the visible light spectrum, are more pronounced under narrowband imaging. Its strength lies in its usefulness in the treatment of patients with endometriosis with symptoms of pain. It is especially useful for those with marked symptoms but, on first glance at laparoscopy, seems to have minimal disease. Narrowband imaging enhances the endometriotic lesions and makes it easier to visualize and identify them, knowing that these subtle lesions may well be the cause of the pain. However, its usefulness is decreased if performed after the initiation of surgery because of the bleeding incurred from dissection, which makes it difficult to distinguish between the red blood cells and endometriotic lesions. CONCLUSION: Narrowband imaging can be used as an adjunct to improve the detection of endometriosis.

Minilaparoscopic hysterectomy made easy: first report on alternative instrumentation and new integrated energy platform.

Minilaparoscopy is an attractive approach for hysterectomy due to advantages such as reduced morbidities and enhanced cosmesis. However, it has not been popularized due to the lack of suitable instruments and high technical demand. We aim to highlight the first case of minilaparoscopic hysterectomy reported in Asia and the use of a new integrated energy platform, Thunderbeat. We would like to propose an alternative method of instrumentation, so as to improve the feasibility and safety of minilaparoscopic hysterectomy. The first minilaparoscopic hysterectomy in Singapore was successfully completed using the alternative instrumentation and new energy platform. There was no conversion or complication during the surgery. The patient recovered uneventfully. To our knowledge, this is the first report on the use of such alternative instrumentation. This approach in instrumentation and the new energy platform will improve the feasibility and speed of the surgery and ensure safety in our patients.

Single-port endo-laparoscopic surgery in combined abdominal procedures.

Single-port endo-laparoscopic surgery has gained support in the surgical community because it is perceived to offer a better postoperative outcome as it requires only a single incision. We write this prospective observational study to ascertain the feasibility and safety of this technique in patients otherwise requiring two operations. Five patients who underwent double procedures with a single-port device were reviewed: Case 1, a transabdominal preperitoneal hernia repair and gastric wedge resection; Case 2, cholecystectomy and diaphragmatic hernia repair; Case 3, oophorectomy and incisional hernia repair; Case 4, anterior resection of the rectum and hepatic segmentectomy; and Case 5, left adrenalectomy and cholecystectomy. Patient demographics, type of port used, operative time, complications and incision length were collected. Mean operative time for the cases ranged from 100 to 315 min. Incision length for the single-port device was 2 cm. In Case 2, an additional 5-mm port was used and an intraoperative complication involving a laceration of the liver occurred during the suturing of the gallbladder fundus. An additional 8-cm lower abdominal incision (Pfannenstiel) was required in Case 4 to complete the colonic anastomosis and for specimen retrieval. Single-port endo-laparoscopic surgery is a feasible and safe technique for approaching double procedures. It drastically reduces the number of scars that a double procedure creates, and if difficulty arises, another port can always be added to ease the operation. It can also potentially reduce the number of admissions and anesthesia that a patient undergoes.

Get "real" with hysteroscopy using the pig bladder: a "uterine" model for hysteroscopy training.

INTRODUCTION: This study aimed to develop a realistic and lifelike uterine model for the training of hysteroscopy skills. MATERIALS AND METHODS: A lifelike "uterine" model was constructed using female pig bladder. The pig bladder was enclosed within a malleable mould, with both ureters blocked by pins. Both rigid and flexible hysteroscopes were used in this study. RESULTS: Basic diagnostic hysteroscopy can be performed in the usual fashion using this lifelike model. The cost of each learning station is minimal. Pig bladder accurately simulates the human uterus with its realistic tactile feel, and conditions in the surgical environment, including obscuration of vision by debris, uterine "folds", realistic "ostia", incomplete shearing of tissue, "uterine" perforation, etc. CONCLUSION: This low-cost novel model provides realistic tissue resistance and yields an almost anatomically accurate hysteroscopic training tool, thereby allowing trainees to effectively acquire both diagnostic and therapeutic hysteroscopic skills.

Main Outcome Measure(s). Conversion to standard laparoscopic technique or laparotomy, estimated blood loss, operative time , extent of scarring, occurrence of intra- and perioperative surgical complications, technical adequacy, and clinical outcome. Result(s). No conversion to standard laparoscopic technique or laparotomy, and no intraoperative or postoperative complications were observed. Total operative time was 99 minutes. The patient was discharged home on postoperative day one. Conclusion(s). Laparoendoscopic single-site bilateral salpingo-oophorectomy of a large ovarian tumour is feasible with standard laparoscopic instruments. It is safe and effective, with good results in terms of excellent cosmesis and minimal postoperative pain.

Gynaecologic robot-assisted cancer and endoscopic surgery (GRACES) in a tertiary referral centre.

INTRODUCTION: Robotic-assisted gynaecologic surgery is gaining popularity and it offers the advantages of laparoscopic surgery whilst overcoming the limitations of operative dexterity. We describe our experience with the fi rst 40 cases operated under the GRACES (Gynaecologic Robot- Assisted Cancer and Endoscopic Surgery) programme at the Department of Obstetrics & Gynecology, National University Hospital, Singapore. MATERIALS AND METHODS: A review was performed for the fi rst 40 women who had undergone robotic surgery, analysing patient characteristics, surgical timings and surgery-related complications. All cases were performed utilising the da Vinci® surgical system (Intuitive Surgical, Sunnyvale, CA) with 3 arms and 4 ports. Standardised instrumentation and similar cuff closure techniques were used. RESULTS: Seventeen (56%) were for endometrial cancer and the rest, for benign gynaecological disease. The mean age of the patients was 52.3 years. The average docking time was 11 minutes (SD 0.08). The docking and operative times were analysed in tertiles. Data for patients with endometrial cancer and benign cases were analysed separately. There were 3 cases of complications- cuff dehiscence, bleeding from vaginal cuff and tumour recurrence at vaginal vault. CONCLUSION: Our caseload has enabled us to replicate the learning curve reported by other centres. We advocate the use of a standard instrument set for the fi rst 20 cases. We propose the following sequence for successful introduction of robot-assisted gynaecologic surgery - basic systems training, followed shortly with a clinical case, and progressive development of clinical competence through a proctoring programme.

An unexpected presentation of endometriosis--a "parasitic" cyst of the bowel in a menopausal woman on hormone therapy.

INTRODUCTION: This report describes a "parasitic" endometriotic cyst of the small bowel. CLINICAL PICTURE: A menopausal woman with a pelvic mass presenting years after commencing hormone therapy. TREATMENT: We performed laparoscopic excision of a cystic tumour attached to the small bowel with a solitary vascular pedicle. OUTCOME: Histology confirmed it to be an endometriotic cyst of ovarian origin, probably resulting from spillage during previous surgery and reactivation with hormone therapy. CONCLUSIONS: We discuss the possible aetiology of this unusual presentation of endometriosis and review the literature on parasitic gynaecological tumours.
