Improving the Diagnostic Yield of High-Resolution Esophageal Manometry for GERD: The "Straight Leg-Raise" International Study.

BACKGROUND & AIMS: The straight leg raise (SLR) maneuver during high-resolution manometry (HRM) can assess esophagogastric junction (EGJ) barrier function by measuring changes in intraesophageal pressure (IEP) when intra-abdominal pressure is increased. We aimed to determine whether increased esophageal pressure during SLR predicts pathologic esophageal acid exposure time (AET). METHODS: Adult patients with persistent gastroesophageal reflux disease (GERD) symptoms undergoing HRM and pH-impedance or wireless pH study off proton pump inhibitor were prospectively studied between July 2021 and March 2022. After the HRM Chicago 4.0 protocol, patients were requested to elevate 1 leg at 45º for 5 seconds while supine. The SLR maneuver was considered effective when intra-abdominal pressure increased by 50%. IEPs were recorded 5 cm above the lower esophageal sphincter at baseline and during SLR. GERD was defined as AET greater than 6%. RESULTS: The SLR was effective in 295 patients (81%), 115 (39%) of whom had an AET greater than 6%. Hiatal hernia (EGJ type 2 or 3) was seen in 135 (46%) patients. Compared with patients with an AET less than 6%, peak IEP during SLR was significantly higher in the GERD group (29.7 vs 13.9 mm Hg; P < .001). Using receiver operating characteristic analysis, an increase of 11 mm Hg of peak IEP from baseline during SLR was the optimal cut-off value to predict an AET greater than 6% (area under the receiver operating characteristic curve, 0.84; sensitivity, 79%; and specificity, 85%), regardless of the presence of hiatal hernia. On multivariable analysis, an IEP pressure increase during the SLR maneuver, EGJ contractile integral, EGJ subtype 2, and EGJ subtype 3, were found to be significant predictors of AET greater than 6% CONCLUSIONS: The SLR maneuver can predict abnormal an AET, thereby increasing the diagnostic value of HRM when GERD is suspected.

Diagnosis and laparoscopic management of a rare endometriosis-related peritoneal mass with rapid growth in early pregnancy.

Herein is described the diagnosis, clinical management and laparoscopic removal of a rapid growing retro-uterine mass in a pregnant woman. After laparoscopic removal of the pelvic mass, diagnosis of peritoneal endometriotic cyst was made on histology. The patient was asymptomatic and no history of endometriosis was reported. The laparoscopic management of the peritoneal mass was safe and effective and to our knowledge this is the first case report describing a decidualized endometriotic lesion in the absence of a pre-pregnancy endometriosis diagnosis.

Esophageal motor disorders across ages: A retrospective multicentric analysis.

BACKGROUND: Age-related changes in the gastrointestinal system are common and may be influenced by physiological aging processes. To date, a comprehensive analysis of esophageal motor disorders in patients belonging to various age groups has not been adequately reported. METHODS: We conducted a retrospective assessment of high-resolution manometry (HRM) studies in a multicenter setting. HRM parameters were evaluated according to the Chicago Classification version 4.0. Epidemiological, demographic, clinical data, and main manometric parameters, were collected at the time of the examination. Age groups were categorized as early adulthood (<35 years), early middle-age (35-49 years), late middle-age (50-64 years), and late adulthood (≥65 years). RESULTS: Overall, 1341 patients (632, 47.0% male) were included with a median age of 55 years. Late adulthood patients reported more frequently dysphagia (35.2%) than early adulthood patients (24.0%, p = 0.035), early middle-age patients (21.0%, p < 0.0001), and late middle-aged patients (22.7%, p < 0.0001). Esophagogastric junction outflow obstruction was more prevalent in late adulthood (16.7%) than in early adulthood (6.1%, p = 0.003), and in early middle-age (8.1%, p = 0.001). Patients with normal esophageal motility were significantly younger (52.0 years) than patients with hypercontractile esophagus (61.5 years), type III achalasia (59.6 years), esophagogastric junction outflow obstruction (59.4 years), absent contractility (57.2 years), and distal esophageal spasm (57.0 years), in multivariate model (p < 0.0001). CONCLUSION: The rate of esophageal motor disorders is higher in older patients, in particular esophagogastric junction outflow obstruction and hypercontractile esophagus. Future prospective studies are necessary to confirm our results and to find tailored strategies to improve clinical outcomes.

The Milan score: A novel manometric tool for a more efficient diagnosis of gastro-esophageal reflux disease.

OBJECTIVE: A definitive diagnosis of gastroesophageal reflux disease (GERD) depends on endoscopic and/or pH-study criteria. However, high resolution manometry (HRM) can identify factors predicting GERD, such as ineffective esophageal motility (IEM), esophago-gastric junction contractile integral (EGJ-CI), evaluating esophagogastric junction (EGJ) type and straight leg raise (SLR) maneuver response. We aimed to build and externally validate a manometric score (Milan Score) to stratify the risk and severity of the disease in patients undergoing HRM for suspected GERD. METHODS: A population of 295 consecutive patients undergoing HRM and pH-study for persistent typical or atypical GERD symptoms was prospectively enrolled to build a model and a nomogram that provides a risk score for AET > 6%. Collected HRM data included IEM, EGJ-CI, EGJ type and SLR. A supplemental cohort of patients undergoing HRM and pH-study was also prospectively enrolled in 13 high-volume esophageal function laboratories across the world in order to validate the model. Discrimination and calibration were used to assess model's accuracy. Gastroesophageal reflux disease was defined as acid exposure time >6%. RESULTS: Out of the analyzed variables, SLR response and EGJ subtype 3 had the highest impact on the score (odd ratio 18.20 and 3.87, respectively). The external validation cohort consisted of 233 patients. In the validation model, the corrected Harrel c-index was 0.90. The model-fitting optimism adjusted calibration slope was 0.93 and the integrated calibration index was 0.07, indicating good calibration. CONCLUSIONS: A novel HRM score for GERD diagnosis has been created and validated. The MS might be a useful screening tool to stratify the risk and the severity of GERD, allowing a more comprehensive pathophysiologic assessment of the anti-reflux barrier.

Reduction of Fecal Calprotectin Levels Induced by a Short Course of Escherichia Coli Nissle is Associated with a Lower Likelihood of Disease Flares in Patients with Ulcerative Colitis in Clinical Remission.

BACKGROUND AND AIMS: Fecal calprotectin (FC) is a biomarker of gut inflammation, and Escherichia coli Nissle 1917 (EcN) is a probiotic strain able to reduce gut inflammation and maintain disease remission in patients with inflammatory bowel disease (IBD). The aim is to assess the effects of EcN administration in patients with IBD in clinical remission and altered FC values. METHODS: We prospectively included 82 patients with ulcerative colitis (UC) (n=49) and Crohn's disease (CD) (n=33) in clinical remission and with FC values above 250 mcg/g (T0) who were treated with EcN alone for 2 months. FC values were assessed at the end of EcN treatment (T1) and clinical disease activity at 3 months (T2). RESULTS: At T1 median FC values were significantly lower compared to T0 both in patients with CD (312 mcg/g vs 626 mcg/g, p<0.0001) and UC (100 mcg/g vs 584 mcg/g; p<0.0001). Patients with UC who experienced disease relapse at T2 had lesser reduction in median FC values at T1 (-229 mcg/g, vs -397 mcg/g, p=0.049), while in patients with CD we observed no statistically significant difference (-358 mcg/g, vs -427; p=0.568). In patients with UC, a reduction of at least 532 mcg/g in FC had an accuracy of 69.7% and a positive predictive value of 65.7% in predicting maintenance of remission. CONCLUSIONS: A short course of EcN was associated with a reduction of FC values in patients with IBD in clinical remission and baseline altered FC values, and in patients with UC this decrease was associated with maintenance of clinical remission.

A case report of nasal endometriosis in a patient affected by Behcet's disease.

We present a case of nasal endometriosis, an uncommon extrapelvic implantation of endometriotic tissue. A woman with a history of pelvic endometriosis and Behcet's syndrome was diagnosed with nasal endometriosis after episodes of perimenstrual epistaxis and nasal pain. Despite being rare, the presence of catamenial symptoms and the possibility of performing endoscopic biopsy allowed us to make the diagnosis of nasal endometriosis. The simultaneous presence of Behcet's syndrome focused our attention on the pathogenesis and the therapeutic management of endometriosis.

Effect of contrast-enhanced ultrasound (CEUS) on liver stiffness measurements obtained by transient and shear-wave elastography.

BACKGROUND: Since liver fibrosis is one of the most accurate predictors of prognosis in hepatopatic patients, its accurate assessment and staging is a major public health issue. Transient elastography (TE) (Fibroscan, Echosens, Paris, France) and shear wave elastography (SWE) represent the gold standard techniques among non-invasive methods to assess liver fibrosis. Contrast-enhanced ultrasound (CEUS) is increasingly used to diagnose the nature of liver lesions and is often performed together with TE and SWE. In this study we evaluated the effect of CEUS on liver stiffness measurements obtained by TE and SWE. METHODS: A retrospective analysis of ultrasound (US) exams performed by an expert operator was carried out. TE and SWE were performed 30 seconds before and after the execution of CEUS. Statistical analysis was carried out using the statistical software R. Kolmogorov-Smirnov analysis was performed to test the normality of continuous variables. The pre- and post-CEUS liver stiffness values were compared using the Wilcoxon's Test. RESULTS: Ninety-six patients were enrolled. While the measurements were comparable when performed with TE, those obtained by SWE decreased by 6% after administration of the contrast agent (P=0.0005). Fibrosis stage deviated between pre- and post-CEUS in 16 (17%) patients with Fibroscan and 22 (23%) patients with SWE. Among the latter, in 9 cases (10%) a deviation from absent-low (F0-F2) to high-fibrosis (F3, F4), or vice versa, occurred. CONCLUSIONS: Our study, the first to assess the effects of CEUS on US elastography, shows that the contrast agent (Sonovue, Bracco Suisse SA, Cadempino, Switzerland) does not significantly affect liver stiffness measurements obtained by TE, whereas the accuracy decreases when performed by SWE.

Does laparoscopic management of deep infiltrating endometriosis improve quality of life? A prospective study.

BACKGROUND: Deep infiltrating endometriosis (DIE) can affect importantly patients' quality of life (QOL). The aim of this study is to evaluate the impact of the laparoscopic management of DIE on QOL after six months from treatment. METHODS: It is a prospective cohort study. In a tertiary care university hospital, between April 2008 and December 2009, 100 patients underwent laparoscopic management of DIE and completed preoperatively and 6-months postoperatively a QOL questionnaire, the short form 36 (SF-36).Quality of life was measured through the SF-36 scores. Intra-operative details of disease site, number of lesions, type of intervention, period of hospital stay and peri-operative complications were noted. RESULTS: Six months postoperatively all the women had a significant improvement in every scale of the SF-36 (p < 0,0005). Among patients with intestinal DIE, significant differences in postoperative scores of SF-36 were not detected between patients submitted to nodule shaving and segmental resection (p > 0.05). There was no significant difference in the SF-36 scores at 6 months from surgery between patients who received postoperative medical treatment and patients who did not (p > 0.05). CONCLUSIONS: Laparoscopic excision of DIE lesions significantly improves general health and psycho-emotional status at six months from surgery without differences between patients submitted to intestinal segmental resection or intestinal nodule shaving.

Does exist a correlation between endometriosis and thrombophilic disorders? A pilot study.

OBJECTIVE: At present, there is growing evidence of the existence of a genetic predisposition in both thrombophilic disorders and endometriosis. The aim of our study was to evaluate for the first time the prevalence of some thrombophilic disorders in patients with endometriosis. MATERIALS AND METHODS: We conducted a retrospective study on 138 patients with endometriosis and 278 healthy control women. All women were subjected to a blood examination testing for thrombophilic screening and the variables examinated were: hyperhomocysteinemia, factor V Leiden and factor II prothrombin G20210A mutations in heterozygosis and homozigosis. RESULTS: A significant reduced prevalence (p < 0.05) of factor V Leiden mutation in endometriosis patients was found, whereas no significant differences (p = NS) for factor II and hyperhomocysteinemia were observed. CONCLUSION: Our preliminary data do not show any association between thrombophilic condition and endometriosis. Before assuming hormonal therapies, a thrombophilic plasmatic screening seems to be unnecessary in patients affected by endometriosis.

Performance of Circulating Placental Growth Factor as A Screening Marker for Diagnosis of Ovarian Endometriosis: A Pilot Study.

BACKGROUND: The aim of this study is to compare the circulating placental growth factor (PlGF) concentration in women with and without endometrioma to verify the performance of this marker to diagnose the disease. MATERIALS AND METHODS: In this case-control study, thirteen women with histological diagnosis of ovarian endometriosis were compared with women without endometriosis disease. PlGF plasma levels of endometriotic patients and controls were investigated using a fluorescence immunoassay technique. RESULTS: PlGF showed a direct correlation with body mass index (BMI) only in the control group (P=0.013). After adjustment for BMI values, PlGF median value in endometriosis group (14.7 pg/mL) resulted higher than in control group (13.8 pg/ mL, P=0.004). CONCLUSION: PlGF is a promising peripheral blood marker that can discriminate between patients with and without ovarian endometriosis.

Sexual function in women undergoing surgery for deep infiltrating endometriosis: a comparison with healthy women.

BACKGROUND: Endometriosis is a chronic and progressive condition of women of reproductive age. It is strongly associated with significant impairment of sexual function. AIM: To objectively evaluate the impact of laparoscopic excision of endometriosis on sexual function in patients with deep infiltrating endometriosis (DIE) compared to healthy women. SETTING AND DESIGN: Prospective study, including 250 patients with a diagnosis of DIE scheduled for laparoscopic surgery and 250 healthy women. METHODS: A sexual activity questionnaire, SHOW-Q (Sexual Health Outcomes in Women Questionnaire), was used to collect data pertaining to women's satisfaction, orgasm, desire and pelvic problem interference with sexual function. Women with DIE underwent complete excision of endometriotic lesions. All participants were asked to complete the SHOW-Q questionnaire before and after surgery. RESULTS: SHOW-Q scores in the endometriosis group before and 6 months after surgery were compared with the healthy group scores. A significant improvement was found between pre- and post-treatment in the scores of the satisfaction scale, desire scale and pelvic problem interference scale of SHOW-Q. The distribution of post-surgery SHOW-Q scores was comparable to healthy women's scores apart from the orgasm scale score, which was unchanged in the post-surgery group. CONCLUSIONS: The surgical approach to treatment has a positive impact not only on organ impairment but also on sexual function in women affected by DIE.

Laparoscopic fertility sparing management of cervical cancer.

Fertility can be preserved after conservative cervical surgery. We report on a 29-year-old woman who was obese, para 0, and diagnosed with cervical insufficiency at the first trimester of current pregnancy due to a previous trachelectomy. She underwent laparoscopic transabdominal cervical cerclage (LTCC) for cervical cancer. The surgery was successful and she was discharged two days later. The patient underwent a caesarean section at 38 weeks of gestation. Laparoscopic surgery is a minimally invasive approach associated with less pain and faster recovery, feasible even in obese women.
