Zheng Y, Gu S, Ruan J, Yi X, Xu C. Bowel wall thickness measured by MRI is useful for early diagnosis of bowel endometriosis. Eur Radiol 2023; 33:9244-9253. [PMID: 37498383 PMCID: PMC10667399 DOI: 10.1007/s00330-023-09795-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 04/03/2023] [Accepted: 04/27/2023] [Indexed: 07/28/2023]
Abstract
OBJECTIVE To evaluate MRI features of bowel endometriosis (BE) and verify its clinical significance compared with pathological diagnosis. MATERIALS AND METHODS Since 2018, patients clinically diagnosed with deep endometriosis (DE) and planned to undergo surgery were enrolled prospectively. MRI parameters including traction, thickening sign of the rectum, obliteration of the Douglas Pouch, sign of adenomyosis, and pelvic adhesion were extracted. Uni- and multi-variate analyses were performed to explore their association with pathological diagnosis of BE. ROC curve was utilized to ascertain the appropriate cutoff value for predicting the presence and assessing the severity of BE. RESULTS A total of 226 patients with DE were recruited, and 154 BE cases were pathologically confirmed. Logistic regression analysis revealed that thickness of the rectal wall, traction sign of the rectum, and obliteration of the Douglas Pouch were independent factors to predict the presence of BE with the OR 1.59 (95% CI: 1.29-1.96), 0.24 (95% CI: 0.09-0.67), and 0.17 (95% CI: 0.07-0.40), respectively (p all < 0.01). A cutoff value of 6.0 mm for the thickness of rectal wall resulted in the highest predictive value of BE (specificity: 90.3%; sensitivity: 78.6%). For patients with measured thickness of the rectal wall over 6.0 mm, 72.1% (93/129) was confirmed BE with lesions infiltrated more than muscular layer. CONCLUSION This prospective study indicates that based on precise definition of visualized features on MRI images, BE could be recognized pre-operatively. DE patients with thickness of rectal wall exceeding 6.0 mm have a greater probability of BE. CLINICAL RELEVANCE STATEMENT Based on precise definition of visualized features and accurate measurement on MRI images, bowel infiltrating among deep endometriosis patients could be recognized pre-operatively. KEY POINTS • Precise definition of measurable MRI parameters made it possible for early detection of bowel endometriosis. • Thickening sign, traction sign of the rectum, and obliteration of the Douglas Pouch were typical radiological indicators for bowel endometriosis. • Bowel involvement is more sensitive to be detected among pelvic deep endometriosis patients with the thickness of the rectal wall over 6.0 mm.

Comparison between CT-enterography and MR-enterography for the diagnosis of right-sided deep infiltrating endometriosis of the bowel. Eur J Radiol 2023; 161:110730. [PMID: 36758279 DOI: 10.1016/j.ejrad.2023.110730] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 01/19/2023] [Accepted: 02/02/2023] [Indexed: 02/09/2023]
Abstract
OBJECTIVE To compare computed tomography-enterography (CTE) and magnetic resonance-enterography (MRE) in the detection of right-sided bowel deep infiltrating endometriosis (DIE). MATERIALS AND METHODS Fifty women with DIE who underwent preoperatively CTE and MRE were included. CTE and MRE were first analyzed separately by two independent readers who analyzed five bowel segments (cecum, appendix, ileocecal junction, distal ileum and proximal small bowel [i.e., proximal ileum and jejunum]) for the presence of DIE and then interpreted in consensus. CTE, MRE and CTE with MRE were compared in terms of sensitivity, specificity and accuracy. Interobserver agreement was assessed with kappa (κ) test. RESULTS Using the reference standard 25 out 250 bowel segments were involved by DIE in 18 women and 225 were free of DIE. Sensitivity, specificity, and accuracy of CTE were 60% (95% confidence interval [CI]: 39-79), 93% (95% CI: 89-96) and 90% (95% CI: 85-93) for Reader 1, respectively, and 52% (95% CI: 31-72), 99% (95% CI: 97-100) and 94% (95% CI: 91-97) for Reader 2, with no differences in sensitivity (P = 0.564) and specificity (P = 0.181) between readers and fair interobserver agreement (κ = 0.37). For MRE these figures were 52% (95% CI: 31-72), 92% (95% CI: 88-95) and 88% (95% CI: 84-92) for Reader 1 and 60% (95% CI: 39-79), 99% (95% CI: 96-100) and 95% (95% CI: 91-97) for Reader 2, with no differences in sensitivity (P = 0.157) and specificity (P = 0.061) between readers and fair interobserver agreement (κ = 0.31). Significant differences in sensitivity (20%; 95% CI: 7-41) were found between CTE + MRE vs. CTE alone for Reader 1 and vs. MRE alone for Reader 2 (P = 0.041 for both) CONCLUSION: CTE and MRE have not different sensitivities and convey only fair interobserver agreement but are highly specific for the diagnosis of right-sided bowel DIE. CTE and MRE are complementary because they improve the detection of DIE implants when used in combination.

Abstract
PURPOSE The purpose of this consensus article was to develop guidelines by a focused panel of experts to elaborate a lexicon of image interpretation, and a standardized region-based reporting of deep infiltrating endometriosis (DIE) with magnetic resonance imaging (MRI). MATERIALS AND METHODS Evidence-based data and expert opinion were combined using the RAND-UCLA Appropriateness Method to attain consensus guidelines. Experts scoring of pelvic compartment delineation and reporting template were collected; responses were analyzed and classified as "RECOMMENDED" versus "NOT RECOMMENDED" (when ≥ 80% consensus among experts) or uncertain (when < 80% consensus among experts). RESULTS Consensus regarding pelvic compartment delineation and DIE reporting was attained using the RAND-UCLA Appropriateness Method. The pelvis was divided in nine compartments and extrapelvic lesions were assigned to an additional (tenth) compartment. A consensus was also reached for each structure attributed to a compartment and each reporting template item among the experts. No consensus was reached for a normal aspect of uterosacral ligament, but a consensus was reached for an unequivocal involvement leading to a positive diagnosis and an equivocal involvement leading to uncertain diagnosis. Tailored MRI lexicon and standardized region-based report were proposed. CONCLUSION These consensus recommendations should be used as a guide for DIE reporting and staging with MRI. Standardized MRI compartment-based structured reporting is recommended to enable consistent accuracy and help select the best therapeutic approach.

Abstract
Abstract
Background
Intestinal obstruction caused by endometriosis maybe easily misdiagnosed as a tumor or other occupying disease in emergency condition. How to deal with it depending on the clarity of the preoperative diagnosis and the experience of the surgeon.
Case presentation
A 47-year-old woman, admitted to our emergency service with abdominal pain and distension for 5 days, anal stop exhausting and defecating for 3 days. Based on imaging and laboratory examination, we made a preoperative diagnosis of rectal endometriosis probably. After 7 days of colon decompression with a intestinal obstruction catheter, an operation of laparoscopic partial rectal and sigmoid resection without protective stoma and total hysterectomy was performed successfully. The patient obtained a smooth postoperative course and doing well after 12-weeks follow up.
Conclusions
Obstruction caused by rectal endometriosis is very rare and easily overlooked by surgeon and gynecologist. Appropriate preoperative diagnosis and preoperative management can reduce the trauma and incidence of complications.

Abstract
Endometriosis is a disease affecting approximately 10% of women of fertile age. A particular presentation is deep infiltrating endometriosis of the rectosigmoid colon with symptoms that can mimic an intestinal obstruction or neoplasm. We report the case of a 39-year-old woman with pelvic pain during the menstrual cycle and significant anemia who presented an ectopic endometrial tissue in correspondence of the rectum. Because of the thickness of the lesion the patient underwent a segmental laparoscopic colorectal resection with end-to-end anastomosis.

Ultrasound prediction of segmental bowel resection in women with rectovaginal endometriosis: a single centre experience. J Minim Invasive Gynecol 2022; 29:1092-1098. [PMID: 35667556 DOI: 10.1016/j.jmig.2022.05.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 05/25/2022] [Accepted: 05/25/2022] [Indexed: 11/19/2022]
Abstract
STUDY OBJECTIVE To retrospectively evaluate the ability of routinely collected pre-operative ultrasound data to predict bowel resection during surgery for rectovaginal endometriosis. DESIGN AND SETTING Patients at University College London Hospital (UCLH) who underwent surgery for rectovaginal endometriosis during a 6-year period were identified from the prospectively generated hospital (BSGE) database. Imaging data were collected and analysed to determine associations with the requirement for bowel resection. PATIENTS We evaluated 228 consecutive women undergoing bowel surgery (shave, disc or segmental resection) for rectovaginal endometriosis. INTERVENTIONS The patients in our study underwent surgical resection of rectovaginal endometriosis and interventions included shave, disc resection and segmental resection of the bowel. All patients underwent a pre-operative transvaginal ultrasound to assess the extent of endometriosis. MEASUREMENTS AND MAIN RESULTS There were 206 (90.4%) rectal shaves, 2 (0.9%) disc resections, and 20 (8.8%) segmental bowel resections. A multivariable analysis demonstrated an association between bowel resection and two or more nodules located in the rectovaginal space (odds ratio 6.85, 95% CI 1.37, 34.2), nodules in the vesico-uterine pouch (odds ratio 5.87, 95% CI 1.03, 33.3), and increasing nodule size (odds ratio 2.39 per 1cm increase per 1cm diameter increase, 95% CI 1.56, 3.64). CONCLUSION Ultrasound findings of endometriotic nodule location, number of nodules, and increasing size are independent predictors of segmental bowel resection at the time of surgery for rectovaginal endometriosis. This highlights the importance of accurate diagnostic evaluation to aid counselling and surgical planning in the pre-operative setting for women with rectovaginal endometriosis.

Abstract
Endometriosis, a common chronic inflammatory disease in female of reproductive age, is closely related to patient symptoms and fertility. Because of its high contrast resolution and objectivity, MRI can contribute to the early and accurate diagnosis of ovarian endometriotic cysts and deeply infiltrating endometriosis without the need for any invasive procedure or radiation exposure. The ovaries, which are the most frequent site of endometriosis, can be afflicted by multiple related conditions and diseases. For the diagnosis of deeply infiltrating endometriosis and secondary adhesions among pelvic organs, fibrosis around the ectopic endometrial gland is usually found as a T2 hypointense lesion. This review summarizes the MRI findings obtained for ovarian endometriotic cysts and their physiologically and pathologically related conditions. This article also includes the key imaging findings of deeply infiltrating endometriosis.

Abstract
Endometriosis is an estrogen-dependent chronic disease affecting about 10% of reproductive-age women with symptoms like pelvic pain and infertility. Pathologically, it is defined by the presence of endometrial tissue outside the uterine cavity responsible for a chronic inflammatory process. For decades the diagnosis of endometriosis was based on surgical exploration and biopsy of pelvic lesions. However, laparoscopy is not a risk-free procedure with possible false negative diagnosis due to an underestimate of retroperitoneal structures such as ureters and nerves. For these reasons nowadays, the diagnosis of endometriosis is based on a noninvasive approach where clinical history, response to therapy and imaging play a fundamental role. Trans-vaginal ultrasound and magnetic resonance imaging are suitable for recognizing most of endometriotic lesions; nevertheless, their accuracy is strictly determined by operators’ experience and imaging technique. This review paper aims to make radiologists aware of the diagnostic possibilities of pelvic MRI and familial with the MR acquisition protocols and image interpretation for women with endometriosis.
