Laparoscopy dye test

OBJECTIVE: Vaginal natural orifice transluminal endoscopic surgery (vNOTES) is an emerging surgical procedure that combines the advantages of the vaginal approach with laparoscopic vision and instrumentation [1]. Shorter hospitalization and lower postoperative pain associated to vNOTES [2] may be explained by the advantages of this innovative surgical approach (such as absence of abdominal incisions, shorter operating time, lower insufflation pressure) [2;3]. Ovarian tissue cryopreservation allows to preserve reproductive and endocrine functions in young women with oncological disease at risk of premature ovarian insufficiency (POI) caused by gonadotoxic treatments [4]...

Sexually transmitted infection is a frequent cause of tubal factor abnormality. Chlamydia trachomatis is a common causative organism for sexually transmitted infection. There are studies indicating association of chlamydial antibodies in serum with tubal abnormalities. In many centers chlamydial antibody test is done as part of routine work up for infertility. The objective of the study was to evaluate the sensitivity and specificity of chlamydial antibody test in screening infertile women for tubal factor infertility...

BACKGROUND: Indocyanine Green (ICG) fluorescence-guided surgery is widely used for intraoperative visualization of lymphatic structures. To date, there are no reports indicating this dye being used in lymph node biopsies for suspected or relapsed lymphoma. METHODS: Between October 2021 and June 2022, 12 patients underwent a fluorescence-guided laparoscopic lymph node biopsy (FGLLB) using ICG. The following was retrospectively evaluated: the dosage of ICG, the injection site, the number of patients where fluorescence was obtained after ICG administration, and additionally, the parameters indicating the outcome of the surgical procedure...

Laparoscopic Heller's cardiomyotomy is the surgical procedure of choice in the management of oesophageal achalasia. It is critical to confirm the completeness of the myotomy and mucosal integrity at the conclusion of the procedure. This is conventionally achieved by intraoperative endoscopy and dynamic air leak test. Other modalities that can be used to confirm the myotomy and the integrity of the mucosa at the myotomy site are oesophageal manometry and a methylene blue dye study, respectively. Indocyanine green (ICG) has been in clinical use for more than six decades...

Current evidence suggests that the hysterosalpingo-foam sonography test (HyFoSy) has emerged as a new option to make Fallopian tube assessment easier. Several published studies have compared the different types of tubal patency test available with the accepted gold standard, laparoscopy and dye, endorsing the advantages of HyFoSy over the other techniques. However, the authors wonder why professionals nowadays do not indicate HyFoSy as a first-choice diagnostic tool, with X-ray hysterosalpingography as still the most recommended procedure in outpatients...

OBJECTIVE: To assess the impact of laparoscopy before in vitro fertilization (IVF) treatment on live birth rates in patients with distal unilateral tubal obstruction (UTO). METHODS: Retrospective cohort study which was conducted in tertiary ART center in Ankara University Hospital between January 2008- January 2019. Inclusion criteria were distal UTO at HSG, patients who were 18-40 years age and baseline serum FSH levels between 3 and 15 IU/ml. Exclusion criteria were patients who had previous tubal surgery and, hormonal dysfunction such as hyperprolactinemia or hypothyroidism at the time of the IVF cycle...

INTRODUCTION: Indocyanine green (ICG) near-infrared fluorescence is primarily employed in detecting Intraoperative sentinel lymph node (SLN) mapping or to evaluate the extent of radical lymphadenectomy mainly in colo-rectal and gastric cancer. To date there are no reports indicating the use of this dye to detect pathologic lymphatic tissue when a lymph node biopsy for suspected lymphoproliferative disease is performed. PRESENTATION OF CASE: A 66-year-old male patient was admitted to the hospital for severe pain of left renal colic type...

BACKGROUND: Totally laparoscopic surgery for early gastric cancer and subepithelial tumors has been popularized worldwide, yet localization of early or small-sized tumors is a persistent challenge due to difficulty being identified with the lack of manual tactile sensation. Thus, accurate localization with tattooing before the surgery would help improve efficiency during surgery. There are multiple methods to localize tumors before laparoscopy, each with varying advantages and disadvantages...

The objective was to assess the method of chromopertubation (CPT) in cases of difficult cannulation to minimize the false-negative cases of tubal block. We had performed laparoscopy and hysteroscopy in 66 females as infertility workup. In all these females, cannulation through the cervical canal was difficult and tubal patency test showed tubal block with Leech-Wilkinson cannula. Then, through the inlet of hysteroscope, methylene blue dye was injected and the patency of tubes was assessed again. In 59 out of the 66 females, we observed that when cannulation and dilation of cervix was difficult, then CPT with hysteroscope showed positive tubal patency test...

OBJECTIVES: The purpose of this study was to evaluate the diagnostic efficacy of transvaginal two-dimensional fundamental sonosalpingography (2D-FS) combined with saline infusion pelvic sonosalpingography (SIPS) for assessing fimbrial part's morphology and function of the fallopian tubes. METHODS: One hundred and sixty-nine cases underwent 2D-FS combined with SIPS. Among them, 18 cases received laparoscopy and dye test (LDT) within 3 months after the examination and the results were regarded as reference standard...

PURPOSE: To determine the benefits and safety of direct trocar insertion versus Veress needle technique in obese women undertaking diagnostic laparoscopy procedures. METHODS: Randomized-controlled trial on 135 obese women undergoing diagnostic laparoscopy and dye test for infertility was conducted. Women were randomly assigned to either direct trocar access (n = 68) or Veress needle access (n = 67) before achieving pneumoperitoneum. The same surgeon executed the laparoscopic techniques with a single-puncture technique...

Endometriosis is a condition in which the endometrium, the layer of tissue that usually covers the inside of the uterus, grows outside the uterus. One of its severe effects is sub-fertility. The exact reason for endometriosis is still unknown and under investigation. Tracking the symptoms is not sufficient for diagnosing the disease. A successful diagnosis can only be made using laparoscopy. During the disease, the amount of some molecules (i.e., proteins, antigens) changes in the blood. Raman spectroscopy provides information about biochemicals without using dyes or external labels...

AIM: Women with adenomyosis are at higher risk of endometriosis recurrence after surgery. This study was to assess if the lymphatic vessel network drained from the uterus to near organs where endometriosis foci lied. METHODS: A prospective, observational study, Canadian Task Force Classification II-2, was conducted at Sacro Cuore Don Calabria Hospital, Negrar, Italy. 104 white women aged 18-43 years were enrolled consecutively for this study. All patients underwent laparoscopy for endometriosis and a tubal dye test was carried out...

BACKGROUND AND OBJECTIVES: Ureters are at risk of injury in settings of inflammation and distorted anatomy. The use of a fluorescent dye can improve intraoperative ureteral identification without the need for any additional invasive procedures. Our team has previously described the development of a preclinical ureter-specific dye, UL-766, tested in a rat model. Here, we present the use of the fluorescent dye during laparoscopy to assist in ureteral identification in a swine model with an inflamed abdomen; the results of this study serve as proof of feasibility for use in the setting of tissue edema and erythema...

Subfertility affects one in seven couples and is defined as the inability to conceive after 1 year of regular unprotected intercourse. This article describes the initial clinical evaluation and investigation to guide diagnosis and management. The primary assessment of subfertility is to establish the presence of ovulation, normal uterine cavity and patent fallopian tubes in women, and normal semen parameters in men. Ovulation is supported by a history of regular menstrual cycles (21-35 days) and confirmed by a serum progesterone >30 nmol/L during the luteal phase of the menstrual cycle...

Objective: This prospective study aimed to investigate the use of real-time three-dimensional hysterosalpingo-contrast sonography (4D-HyCoSy), using contrast agent SonoVue, with B mode hysterosalpingo-contrast sonography (B mode-HyCoSy), to evaluate tubal patency and the wall of the Fallopian tubes in infertility patients. Method: In total, we recruited 739 women with fertility requirements from the First Affiliated Hospital of Shantou Medical College between January 2017 and July 2018...

BACKGROUND: Ureteric injury is reported to occur in 1-7.6% of colorectal surgeries. To reduce the incidence of ureteral injury, it is essential to identify the ureters. The use of near-infrared fluorescence (NIRF) imaging with intravenously administered dyes might be of added value for ureteral visualization during laparoscopy. The aim of this study is to assess the performance of three preclinical dyes; IRDye® 800BK, IRDye® 800NOS and IRDye® 800CW, for near-infrared fluorescence laparoscopy of the ureter in pigs...

Sixty-nine (69) subfertile women who were seropositive for Chlamydia Trachomatis were included in this study. Inclusion criteria was patients with sub-fertility having age between 22 and 40 years, seeking infertility treatment, normal ovarian function, all normozoospermic male partner, duration of infertility ranged from 1...

Ectopic pregnancy occurs in 1-2% of pregnancies. The fallopian tube is the most common site; however, bilateral tubal ectopic pregnancy is an extremely rare phenomenon, seen in approximately 1/200,000 pregnancies. It is usually the result of assisted reproductive techniques (ART). Ultrasound (USS) and serial beta-hCG levels have shown poor efficacy for accurate diagnosis. Laparoscopy is the diagnostic gold standard. The majority of cases are managed surgically with bilateral salpingectomy. A 26-year-old female presented to our early pregnancy unit with pain and vaginal bleeding at 5-week gestation after IVF...

BACKGROUND: Fallopian tube patency testing is an essential part of infertility evaluation. Hysterosalpingo-contrast sonography (HyCoSy) has been described as reliable, well tolerated and safe compared to other modalities such as laparoscopy and a dye test or hysterosalpingography. Limited availability of the previously used contrast has led to the introduction of a foam contrast agent as an alternative. AIMS: To assess the tolerability, safety and occurrence of pregnancy post-procedure of hysterosalpingo-foam sonography (HyFoSy)...
