Augmented Reality with Diffusion Tensor Imaging and Tractography during Laparoscopic Myomectomies

Publication date: Available online 22 November 2019Source: Journal of Minimally Invasive GynecologyAuthor(s): Pauline Chauvet, Nicolas Bourdel, Lilian Calvet, Benoit Magnin, Guillaume Teluob, Michel Canis, Adrien BartoliAbstractAugmented reality is a technology that allows a surgeon to see key hidden subsurface structures in an endoscopic video in real-time. This works by overlaying information obtained from preoperative imaging and fusing it in real-time with the endoscopic image. Magnetic resonance diffusion tensor imaging (DTI) and fiber tractography are known to provide additional information to that obtained from standard structural magnetic resonance imaging (MRI). Here, we report the first 2 cases of the use of real-time augmented reality during laparoscopic myomectomies with visualization of uterine muscle fibers after DTI tractography–MRI to help the surgeon decide the starting point incision.In the first case, a 31-year-old patient was undergoing laparoscopic surgery for a 6-cm FIGO type V myoma. In the second case, a 38-year-old patient was undergoing a laparoscopic myomectomy for a unique 6-cm FIGO type VI myoma. Signed consent forms were obtained from both patients, which included clauses of no modification of the surgery. Before surgery, MRI was performed. The external surface of the uterus, the uterine cavity, and the surface of the myomas were delimited on the basis of the findings of preoperative MRI. A fiber tracking algorithm was used to extrapolate t...

AbstractPurposeThis is a retrospective cohort study that evaluates the postoperative pain findings of a consecutive series of laparoscopic surgeries for deep endometriosis (DE).MethodsThis multi-center retrospective cohort study was carried out in university hospitals (Istanbul, Turkey). Sixty-five patients diagnosed through bimanual gynecologic examination, gynecologic ultrasound or magnetic resonance imaging-confirmed endometrioma and DE together; who underwent a laparoscopic surgery between 2013 and 2019 by a team of gynecologists, colorectal surgeons, and a urologist were retrospectively evaluated. The data were collec...

Abstract BACKGROUND: Laparoscopic hepatectomy has gained popularity in the management of malignant liver lesions in the past decade. Its safety and feasibility, with faster recovery and comparable long-term outcomes, have been widely published. Nonetheless, laparoscopic isolated caudate lobectomy is still rare and technically demanding. We herein present a video on laparoscopic total caudate lobectomy for caudate cholangiocarcinoma. METHODS: The patient is a 61-year-old man who presented with epigastric distending discomfort. A contrast-enhanced magnetic resonance imaging was performed, showing a 4.6 &...

AbstractBackgroundThe incidence of de novo gastroesophageal reflux disease (GERD) after LSG is substantial. However, an objective correlation with the structural gastric and EGJ changes has not been demonstrated yet. We aimed to prospectively evaluate the effects of laparoscopic sleeve gastrectomy (LSG) on the structure and function of the esophagogastric junction (EGJ) and stomach.MethodsInvestigations were performed before and after>  50% reduction in excess body weight (6–12 months after LSG). Subjects with GERD at baseline were excluded. Magnetic Resonance Imaging (MRI), high-resolution manometry (...

Authors: Senarath S, Ades A, Nanayakkara P Abstract Most adnexal masses are benign, incidental findings of pregnancy which resolve spontaneously. They may present clinically due to haemorrhage, rupture, torsion and mass effect. Aetiological classification includes ovarian benign, ovarian malignant, non-ovarian, gynaecological, non-ovarian non-gynaecological and an additional subset of pathologies unique to pregnancy. Ultrasound is the first-line imaging modality for the evaluation of adnexal masses. This may be supplemented with magnetic resonance imaging. Tumour markers support evaluation of malignant potential, b...

Abstract We investigated the relationship between positive surgical margin (PSM)-related factors and biochemical recurrence (BCR) and the ability of intraoperative frozen sections to predict significant PSM in patients with prostate cancer. The study included 271 patients who underwent robot-assisted laparoscopic prostatectomy with bilateral nerve sparing and maximal urethral preservation. Intraoperative frozen sections of the periurethra, dorsal vein, and bladder neck were analyzed. The ability of PSM-related factors to predict BCR and significant PSM was assessed by logistic regression. Of 271 patients, 108 (39....

ConclusionsBased on these data, the higher recurrence risk in the anterior compartment after SSHP cannot be explained. Larger sample sizes, studying women with recurrence or de novo cystocele after SSHP or using an upright MRI scanner would be of interest to further assess the relationship between pelvic organ mobility and the occurrence of anterior vaginal wall prolapse.

Abstract Cancer complicates 1 in 1000 pregnancies. Multidisciplinary consensus comprised of Gynecologic Oncology, Pathology, Neonatology, Radiology, Anesthesiology, Maternal Fetal Medicine, and Social Work should be convened. Pregnancy provides an opportunity for cervical cancer screening, with deliberate delays in treatment permissible for early stage carcinoma. Vaginal delivery is contraindicated in the presence of gross lesion(s) and radical hysterectomy with lymphadenectomy at cesarean delivery is recommended. Women with locally advanced and metastatic/recurrent disease should commence treatment at diagnosis w...

A 12-year-old woman whose chief complaints were not having first menstruation and suffering monthly severe lower abdominal pain. Magnetic resonance imaging (MRI) showed that the uterine body was separated from the uterine cervix (Fig. 1). Diagnostic laparoscopy confirmed that the uterine body was partially agenesis. The uterine cervix and body were connected to each other only with anterior tissues. The right tubal interstitium is not in normal position (Fig. 2). Uterocervical anastomosis was performed under laparoscopy (Fig.

Conclusion: The clinical symptoms of atypical/malignant SFT of the pancreas with spleen vein invasion are not atypical, and imaging feature is lack of specificity. Preoperative diagnosis is difficult, and there is a potential for malignancy. However, due to the paucity of randomized control trials, there is no established, globally accepted treatment strategy, radiation therapy and chemotherapy regimens have not demonstrated global effectiveness, and no standardized treatments have been identified. Therefore, we recommend complete surgical resection and close clinical follow-up.

Authors: D'Ambrosio V, Brunelli R, Musacchio L, Del Negro V, Vena F, Boccuzzi G, Boccherini C, Di Donato V, Piccioni MG, Benedetti Panici P, Giancotti A Abstract Adnexal masses are not common in pregnancy. They are often discovered incidentally during routine ultrasound examinations. In general, 24%-40% of the cases are benign tumors; up to 8% are malignant tumors. Adnexal masses are usually asymptomatic, but sometimes can be responsible for abdominal or pelvic pain. Transvaginal and transabdominal ultrasound is essential to define the morphology of pelvic masses and to distinguish between benign and malignant case...
