Percutaneous Transhepatic Cholecystolithotomy by Holmium Laser for Non-high-Risk Patients with Symptomatic Gallbladder Stones.

Background: The development of gallstones, also known as cholelithiasis, is one of the most common diseases associated with the gastrointestinal tract. In developing countries 10% to 15% of men and >25% of women experience gallstones. Objective: The aim of the study was to evaluate the outcomes following percutaneous transhepatic cholecystolithotomy by holmium laser in non-high-risk patients with symptomatic gallbladder stones. Methods: This was an intervention study without control and with longitudinal follow-up. Subjects included patients who had only gallbladder stones, a normal gallbladder contractility index, and required a conservative treatment. Results: The study included 44 patients (20 men, 24 women), with a mean age of 41.5 ± 13.4 years. The success rate was 97.7%, and only 1 of 44 patients required follow-up laparoscopic cholecystectomy. Gallstones were successfully removed from 43 of 44 patients (97.7%). The complication rate was 13.6% (6/44 patients), and only minor complications were reported for 5 of the 6 patients with complications. In 34 of 43 patients, follow-up examinations were performed after 1 and 6 months. The gallstone recurrence rate at six-month follow-up was 11.8%, and a collapsed gallbladder was detected in 1 of 34 patients, with the remaining 33 patients retaining normal gallbladder contractility indices (>40%). Conclusion: Percutaneous transhepatic cholecystolithotomy by holmium laser has a high gallstone removal rate (97.7%); however, recurrence remains a major problem. The complication rate was about 13.6%, most of which were minor complications. Cases associated with treatment failure or serious complications should be detected and treated promptly.

A case report of secondary bilateral orbital lymphoma in a child.

Lymphoma is one of the most common cancers of the orbital and lacrimal glands, after squamous cell carcinoma and melanoma. Based on cell origin, most lymphoma cases are classified as non-Hodgkin lymphoma. Orbital lymphoma can be either primary or secondary. The clinical manifestations of lymphoma are diverse, with the most common symptoms being bilateral or unilateral proptosis, limited eye motility, swelling, pain, changes in visual acuity, and diplopia. In this article, we describe the case of a 6-year-old male who presented with bilateral rapid orbital swelling for 10 days. This patient underwent surgical biopsy, and the final diagnosis was bilateral orbital secondary non-Hodgkin lymphoma.

Detecting Fetal Central Nervous System Anomalies Using Magnetic Resonance Imaging and Ultrasound.

BACKGROUND: Most fetal abnormalities can be detected on ultrasound, the evaluation of fetal CNS abnormalities can be limited by various factors, including obesity, polyhydramnios, multiple pregnancies, and increased cranial ossification during the third trimester. OBJECTIVE: This study aimed to evaluate the ability to detect fetal central nervous system (CNS) anomalies using in utero magnetic resonance imaging (iuMRI) and ultrasound (US) techniques. METHODS: This prospective study was approved by the institutional review board (Ref: 2968/QD-DHYHN dated 11 July 2019), and the requirement to obtain the informed consent of patients was waived. This study included 66 fetuses with diagnosed or suspected CNS abnormalities based on the results of a prenatal screening US performed at the antenatal diagnosis center of the Central Obstetrics and Gynecology Hospital. All pregnant women with a suspected diagnosis of abnormal fetal CNS on US underwent 1.5-Tesla iuMRI within 14 days of the US at Hanoi Medical University Hospital between June 2019 and June 2020. Cohen's kappa coefficient (κ) was used to determine the agreement between US and iuMRI findings. RESULTS: A total of 66 pregnant women were examined, including 66 fetuses, for which 79 abnormalities were detected by US and 98 abnormalities were detected by iuMRI. The average gestational age was 29 weeks and 6 days. The comparison of iuMRI and US findings revealed similar diagnoses for 71 abnormalities (67%) and different diagnoses for 35 abnormalities (33%). The level of agreement between US and iuMRI was almost perfect for ventriculomegaly and cystic lesions, with κ values 0.87 and 0.84, respectively. The level of agreement between US and iuMRI was the weakest for hemorrhage, with a κ value 0 (no agreement), and cortical abnormalities, with a κ value of 0.46 (weak agreement). CONCLUSION: The level of agreement between US and iuMRI diagnoses was almost perfect for the detection of ventriculomegaly and was weakest for the detection of hemorrhage and cortical abnormalities, which were abnormalities detected by iuMRI but not by ultrasound.

A rare case of inflammatory myofibroblastic tumor of the vulva in a newborn.

Inflammatory myofibroblastic tumor (IMT) is an uncommon neoplasm that rarely arises in the genitourinary system. IMTs in the vulva in infants are extremely rare in the literature. The tumor consists of myofibroblastic spindle cells accompanied by inflammatory cell infiltration. In this article, we aimed to describe the case of IMT in the vulva. A newborn girl presented with a mass in the vulva detected in the prenatal period. The patient was treated with surgery and chemotherapy. Follow-up 8 months after surgery showed no signs of recurrence. In conclusion, IMT has a variable clinical presentation, surgery is the optimal approach, but in cases without complete resection, chemotherapy is essential.

Non-functioning adrenocortical carcinoma.

Adrenocortical carcinoma (ACC) is a rare malignancy that arises from the adrenal cortex and can be classified as either non-functioning or functioning. A patient with non-functioning ACC may present no specific symptoms. Imaging analysis can provide some information to a clinician who suspects ACC, such as tumor size, density, washout, necrosis, hemorrhage, and calcification. Histopathology is used to confirm and determine the origin of the malignancy and can provide relevant prognostic information. Microscopic findings can be used to obtain information such as the Weiss score, resection surface features, Ki-67 proliferative index, and the degree of capsular and vascular invasion. Surgery can be curative for localized tumors, and adjuvant therapy using mitotane and cytotoxic chemotherapy is often employed for advanced-stage tumors. We describe a case report of a 32-year-old man with a non-functioning ACC that highlights the importance of radiological and pathological features in the diagnosis of ACC and their use as prognostic factors.

An Extremely Rare Case of Splenic Rupture Secondary to Metastatic Gestational Choriocarcinoma.

Gestational choriocarcinoma (GC) is an uncommon malignant tumor consisting of trophoblastic cells. The lungs, liver, and central nervous system are the most common metastatic sites for this disease. However, splenic metastasis is unusual and might result in spontaneous rupture. Symptoms associated with splenic rupture may be the first presentation of malignancy. A thorough medical history and examination are necessary to detect the primary lesion. Herein, we present a case of a 23-year-old female who had splenic rupture secondary to choriocarcinoma metastasis. Although the emergency condition had been solved, the patient died 1 month after due to brain metastasis. The goal of this article was to report a new case of spontaneous splenic rupture caused by choriocarcinoma metastasis and to review the existing literature on splenic metastases associated with GC, including the epidemiology and etiology.

Extraperitoneal bladder perforation secondary to transurethral resection of bladder tumor.

Transurethral resection of bladder tumor (TURBT) is one possible treatment approach for bladder tumors. Bladder wall perforation is one potential complication of TURBT. Signs of perforation include abdominal distension, the inability to distend the bladder, and the low retrieval of irrigation fluids. Peritonitis may occur if a perforation diagnosis is delayed. Early detection and diagnosis are crucial for the prevention of severe complications, such as peritonitis and sepsis. Here, we describe a case of a 69-year-old male with a bladder rupture secondary to TURBT.

Value of Diffusion Weighted MRI with Quantitative ADC Map in Diagnosis of Malignant Thyroid Disease.

Thyroid nodule is a common disease in clinical practice. The diagnosis of malignant thyroid tumors determines the treatment strategy. Among a number of methods have claimed to help evaluating thyroid nodules, ultrasound is a usable one in spite of several disadvantages (dependent on the physician/technician, incomparable, etc.) and magnetic resonance imaging (MRI) accompanied by quantitative apparent diffusion coefficient (ADC) is a promising diagnostic tool. This study was designed to investigate the usefulness of ADC cut-off values and the protocol of thyroid MRI derived from quantitative diffusion weighted imaging (DWI) in differentiating benign and malignant thyroid nodules. The study was conducted on 93 patients with 128 thyroid nodules, diagnosed and underwent surgery at Hanoi Medical University Hospital. All the patients took thyroid MRI with different b levels (from 200 to 800). ADC value was calculated to each b level, and the statistical tests were conducted with the Statistical Package for Social Sciences (SPSS-Windows and Mac version 20) and STATA 12. The mean ADC with all the b ranging from 200 to 800 of malignant groups was significantly higher than the group of benign lesions (p from <0.001 to 0.01). We chose b = 500 as a standard b-value in the protocol of thyroid MRI. The ADC cut-off point for distinguishing malignant from benign thyroid lesions: 1.7 × 10-3 mm2/s with high accuracy (87.1%, 95% CI: 79.59-92.07%). The study revealed that quantitative diffusion weighted MRI with ADC measurement could potentially quantitatively differentiate between benign and malignant thyroid nodules.
