Objective: To report a unique surgical procedure that was utilized to locate a missing vibrator in the pelvis of a patient. Emergency room admissions and surgery secondary to the malfunctioning of devices intended for sexual stimulation are extremely common. Emergency room staff of hospitals in the United States usually are skilled in the detection and removal of these devices. Occasionally, surgical intervention is warranted if the device enters a cavity that cannot safely be explored in the emergency room setting. We report a case of a vibrator that was lost during sexual activity. A flat plate X-ray showed it to be in the abdominal cavity. Careful questioning of the patient revealed that the device had an unusually small diameter. Surgical intervention showed that the device ultimately ended up in the bladder without causing traumatic injury. Methods: We created a narrated video to demonstrate the surgical procedure (Canadian Task Force Classification III). Results: Laparoscopy and cystoscopy were used to visualize and successfully remove the device. The patient recovered uneventfully. Conclusion Following laparoscopic confirmation of the location of the device, it was removed via cystoscopy. This case demonstrates how background information, such as the size of the missing device in this case, can be critical to providing high quality patient care.

Interstitial pregnancy is a rare, life-threatening condition that requires high clinical suspicion for diagnosis. Most cases are discovered after complications have occurred. Many authors have described laparoscopic management. Although previous systematic reviews have compared the attributes and complications associated with interstitial pregnancy, we endeavored to complete the first systematic review and meta-analysis to compare the laparoscopic treatment of interstitial pregnancy with the open approach in the modern age of laparoscopic surgery. We systematically searched PubMed, ClinicalTrials.gov, Scopus, Web of Science, and Cochrane until June 2020 using relevant keywords and screened them for eligibility. We found a statistically significant difference in blood loss between laparoscopic and open surgery (168 mL compared to 1,163 mL). Further, cumulative meta-analysis has revealed that blood loss in laparoscopy has been decreasing over time from 1991 to 2020. Laparoscopic patients took less operative time (63.2 minutes) compared to laparotomy patients (78.2 minutes). Patients in the laparoscopic group spent less time hospitalized (3.7 days) compared to laparotomy patients (5.2 days). Our findings add strength to the position that laparoscopic approaches to interstitial pregnancy can be considered first-line in most situations. The laparoscopic approach was found to have a mean blood loss of 168 mL, and this blood loss seems to decrease over time. Increased gravidity and duration of amenorrhea are positive factors that increase bleeding during the procedure. We are unable to find enough high-quality data to significantly compare successful pregnancy following surgery or risk of mortality in these populations.

BACKGROUND: The main challenge in new drug development is accurately predicting the human response in preclinical models. METHODS: In this study, we developed three different intestinal barrier models using advanced biofabrication techniques: (i) a manual model containing Caco-2 and HT-29 cells on a collagen bed, (ii) a manual model with a Caco-2/HT-29 layer on a HDFn-laden collagen layer, and (iii) a 3D bioprinted model incorporating both cellular layers. Each model was rigorously tested for its ability to simulate a functional intestinal membrane. RESULTS: All models successfully replicated the structural and functional aspects of the intestinal barrier. The 3D bioprinted intestinal model, however, demonstrated superior epithelial barrier integrity enhanced tight junction formation, microvilli development, and increased mucus production. When subjected to Ibuprofen, the 3D bioprinted model provided a more predictive response, underscoring its potential as a reliable in vitro tool for drug toxicity testing. CONCLUSION Our 3D bioprinted intestinal model presents a robust and predictive platform for drug toxicity assessments, significantly reducing the need for animal testing. This model not only aligns with ethical testing protocols but also offers enhanced accuracy in predicting human responses, thereby advancing the field of drug development.
