Evaluation and management of urethral foreign bodies and description of a novel ultrasound?guided catheter?based extraction technique

ABSTRACT: Abstract There are numerous reports in the medical literature documenting urethral foreign bodies with nearly all cases found in men and often associated with underlying psychiatric disorders, autoerotic stimulation, and/or intoxication. Patients most commonly presented with localized penile pain, hematuria, dysuria, and occasionally obstruction. Although endoscopic removal by a urologist is often the first?line treatment, this report describes evaluation and management considerations and presents a novel extraction technique that may allow emergency physicians in consultation with urology to perform removal of some unusual urethral foreign bodies in the emergency department. We report a novel extraction technique using a pediatric foley catheter under ultrasound guidance that has been applied during multiple encounters with 2 individuals who have each presented multiple times at a single emergency department (ED) for evaluation because of urethral foreign body insertion. The foreign body materials have ranged from small pieces of rubber to cellophane to styrofoam and most commonly plastic utensils. Urologic extraction may be required in some cases, but ED removal can be considered. A final discussion of the creation of a multidisciplinary care plan to address resource use concerns also is described.

Project description:PurposeTo evaluate and compare the efficacy of intermittent needle aspiration and continuous catheter drainage in ultrasound-guided management of liver abscesses.MethodsThis was a prospective, randomised study conducted on 100 patients (88 males and 12 females; age range 22-74 years) with liver abscess(es) and having abscess size more than 5 cm, divided into two groups: Percutaneous needle aspiration (PNA) (n = 50) and percutaneous catheter drainage (PCD) (n = 50). Criteria of exclusion were: rupture of abscess before intervention; prior intervention; uncorrectable coagulopathy; concomitant biliary tract malignancy. In the PNA group, pus was aspirated by an 18-gauge needle using freehand technique and the number of aspirations was limited to two. Failure of abscess size to decline below 50% of the original diameter or of clinical improvement after second aspiration was considered as failure of aspiration. In the PCD group, drainage was done by 12-French catheters using Seldinger technique. Drainage was considered as failure if abscess cavity did not resolve and laparotomy was needed to evacuate the pus cavity.ResultThe success rate in the PNA group was 88% and 92% in the PCD group; however, this difference was statistically not significant, suggesting that both are equally efficacious. The total duration of hospital stay (mean 6.8 days [PNA] vs 10.5 days [PCD]; p value: 0.011) and the average duration between intervention and discharge (5.9 days [PNA] vs 10.2 days [PCD]; p value:0.026) were significantly less in the PNA group. One major complication was seen in our study: peritonitis due to peri-catheter leak in PCD group.ConclusionBoth procedures are equally efficacious in the management of liver abscesses; however in view of less duration of hospital stay, patient safety and comfort, procedure simplicity, and the reduced cost, needle aspiration should be used as the first-line procedure in the treatment of liver abscess (even in abscesses more than 5 cm). Catheter drainage should be reserved for cases that do not respond to a second attempt of aspiration.

Project description:ObjectiveEmerging evidence suggests that chest radiography (CXR) following central venous catheter (CVC) placement is unnecessary when point-of-care ultrasound (POCUS) is used to confirm catheter position and exclude pneumothorax. However, few providers have adopted this practice, and it is unknown what contributing factors may play a role in this lack of adoption, such as ultrasound experience. The objective of this study was to evaluate the diagnostic accuracy of POCUS to confirm CVC position and exclude a pneumothorax after brief education and training of nonexperts.MethodsWe performed a prospective cohort study in a single academic medical center to determine the diagnostic characteristics of a POCUS-guided CVC confirmation protocol after brief training performed by POCUS nonexperts. POCUS nonexperts (emergency medicine senior residents and critical care fellows) independently performed a POCUS-guided CVC confirmation protocol after a 30-minute didactic training. The primary outcome was the diagnostic accuracy of the POCUS-guided CVC confirmation protocol for malposition and pneumothorax detection. Secondary outcomes were efficiency and feasibility of adequate image acquisition, adjudicated by POCUS experts.ResultsTwenty-six POCUS nonexperts collected data on 190 patients in the final analysis. There were five (2.5%) CVC malpositions and six (3%) pneumothoraxes on CXR. The positive likelihood ratios of POCUS for malposition detection and pneumothorax were 12.33 (95% confidence interval [CI] = 3.26 to 46.69) and 3.41 (95% CI = 0.51 to 22.76), respectively. The accuracy of POCUS for pneumothorax detection compared to CXR was 0.93 (95% CI = 0.88 to 0.96) and the sensitivity was 0.17 (95% CI = 0.00 to 0.64). The median (interquartile range) time for CVC confirmation was lower for POCUS (9 minutes [8.5-9.5 minutes]) compared to CXR (29 minutes [1-269 minutes]; Mann-Whitney U, p < 0.01). Adequate protocol image acquisition was achieved in 76% of the patients.ConclusionThirty-minute training of POCUS in nonexperts demonstrates adequate diagnostic accuracy, efficiency, and feasibility of POCUS-guided CVC position confirmation, but not exclusion of pneumothorax.

Project description:BackgroundPatients with a rectal foreign body (RFB) are still a rare entity in general surgery departments but with an increasing incidence over the last years. This case is sometimes difficult to treat, and due to a lack of standardized treatment options, the aim of the study was to present our clinical experiences with the diagnostic and therapeutic approach to RFBs and a review of the currently available literature.Materials and methodsData were collected retrospectively from the patient's records of 20 patients who were treated due to an RFB between 2006 and 2016. Patient's demographics, circumstances of insertion, inserted objects, clinical presentation, laboratory and imaging results, as well as surgical treatment and duration of hospital stay were analyzed. Additionally, a review of the literature was performed with the search items "rectal foreign body" and "surgical therapy". Because many publications were just case reports, we did not perform a meta-analysis or a systematic review.ResultsTwenty-two cases in 20 patients (80% male) presented to the emergency room. The mean age was 38.5±13.7 years. In 68.2% of the cases, the cause of RFB was due to sexual preferences. The following objects were inserted: six dildos, three vibrators, two bottles, one glass, one deodorant, one apple, one fever thermometer, multiple glass fragments and razor blades in one patient and six unknown objects. For 18 RFBs, manual peranal removal without anesthesia was possible in the emergency room, but two patients required intravenous analgesia. Two patients were transferred to the operating room and the foreign body was removed via the anus under general anesthesia. Open surgery with a laparotomy was necessary for two complicated cases. One patient was in need of surgery due to a vacuum generated by the RFB, whereas the second patient suffered from a sigmoid perforation. In all cases, there was no morbidity or mortality.ConclusionIn most cases, the removal of an RFB can be performed peranally in the emergency room without further complications, therefore representing the therapy of choice for RFB. Only in cases with perforation, acute abdomen, or failed peranal approaches, surgery is indicated to remove the foreign body.
