Multidisciplinary surgical management of severe posterior compartment endometriosis

Background Endometriosis is a chronic, infammatory, and hormone-dependent disease that afects approximately 10% of women in reproductive age. Endometriosis is categorized into diferent types, as superfcial, deep, and ovarian endometriosis. When deep endometriosis occurs, the sigmoid and rectum are often afected (Becker et al. in Hum Reprod Open, 2022, https://doi.org/10.1093/hropen/hoac009). In the following article, we aim to demonstrate stepwise surgery for stage IV endometriosis involving the anterior rectosigmoid. Methods We present the case of a 26-year-old obese (BMI 35.87) woman with severe posterior pelvic compartment endometriosis, persistent abdominal pain, and constipation. On preoperative MRI of the pelvis, a 13 cm conglomerate incorporating both ovaries (kissing ovaries), uterine serosa, and the anterior rectosigmoid was observed (Fig. 1). Accordingly, interdisciplinary laparoscopic surgery with a gynecologist and colorectal surgeon was planned. Results The total laparoscopic approach is demonstrated step by step in the video. Conclusions Deep endometriosis is a rare condition. When involvement of other organs (e.g., the bowel) is suspected, preoperative endometriosis-specifc imaging should be performed for optimal surgical planning. Experienced endometriosis multidisciplinary surgical teams can provide specialized and high-quality care for patients sufering from this debilitating disease (Luna Russo et al. in Minerva Ginecol, 2020, https://doi.org/10.23736/S0026-4784.20.04544-X)

Global Irradiation in Children Treated for Hydrocephalus and Its Change over Time—A Single Institutional Analysis

Radiation exposure early in life is associated with greater incidences of malignancy. Our goal was to quantify radiation exposure in shunt-treated hydrocephalus patients and study changes in the diagnostic modalities used. A single-center, retrospective analysis was performed, and 41 children treated for hydrocephalus using an adjustable ventriculoperitoneal shunt were identified. Diagnostics associated with hydrocephalus and other comorbidities were analyzed and radiation exposure was calculated. During 330.09 total shunt years, patients were exposed to a mean hydrocephalus-associated radiation dose of 3.93 mSv (range: 0–24.38 mSv), which amounted to a mean rate of 0.49 mSv per shunt year, respectively. Radiation exposure was greatest after shunt insertion in the first year of life. A continuous change from CT scans to MRIs could be seen over the study period, such that patients who underwent shunt insertion after 2017 were not exposed to additional hydrocephalus-associated radiation during their first year of life. Nevertheless, our patients, and a few individuals especially, seemed to be at higher risk for radiation sequelae. Our results suggest that CT scans should be substituted with MRIs, which decrease overall radiation exposure and can lead to zero additional radiation exposure during the first year of life after shunt insertion

Volatile Organic Compounds, Bacterial Airway Microbiome, Spirometry and Exercise Performance of Patients after Surgical Repair of Congenital Diaphragmatic Hernia

The aim of this study was to analyze the exhaled volatile organic compounds (VOCs) profile, airway microbiome, lung function and exercise performance in congenital diaphragmatic hernia (CDH) patients compared to healthy age and sex-matched controls. A total of nine patients (median age 9 years, range 6–13 years) treated for CDH were included. Exhaled VOCs were measured by GC–MS. Airway microbiome was determined from deep induced sputum by 16S rRNA gene sequencing. Patients underwent conventional spirometry and exhausting bicycle spiroergometry. The exhaled VOC profile showed significantly higher levels of cyclohexane and significantly lower levels of acetone and 2-methylbutane in CDH patients. Microbiome analysis revealed no significant differences for alpha-diversity, beta-diversity and LefSe analysis. CDH patients had significantly lower relative abundances of Pasteurellales and Pasteurellaceae. CDH patients exhibited a significantly reduced Tiffeneau Index. Spiroergometry showed no significant differences. This is the first study to report the VOCs profile and airway microbiome in patients with CDH. Elevations of cyclohexane observed in the CDH group have also been reported in cases of lung cancer and pneumonia. CDH patients had no signs of impaired physical performance capacity, fueling controversial reports in the literature
