A case of H-type double gallbladder anomaly: A case report.

RATIONALE: Biliary system anomalies, such as duplicated gallbladders, are rare congenital conditions that present significant diagnostic challenges. Dr. Boyden's classification system, especially the H-type anomaly, offers vital insight into these variations. Failure to detect these anomalies preoperatively can increase the risk of surgical complications, making early identification crucial for surgical planning. PATIENT CONCERN: A 42-year-old male, asymptomatic, was incidentally found to have a gallbladder mass during routine imaging. An upper abdominal magnetic resonance imaging showed gallbladder wall thickening, gallstones, and a liver lesion. Despite the absence of symptoms, a laparoscopic cholecystectomy revealed an atrophied gallbladder with a cystic duct cyst, which was identified as an H-type double gallbladder anomaly. The surgery was completed without complications, and pathology confirmed the presence of gallstones and inflammation. DIAGNOSES: The patient was diagnosed with a duplicated gallbladder, classified as an H-type anomaly, following laparoscopic cholecystectomy. Preoperative imaging identified gallbladder wall thickening and gallstones, and further investigation during surgery confirmed the congenital anomaly. INTERVENTIONS: The patient underwent laparoscopic cholecystectomy for the removal of the gallbladder, and during the procedure, an H-type double gallbladder anomaly was discovered. The surgery proceeded without incident, ensuring the complete excision of the gallbladders. OUTCOMES: The case highlights the diagnostic difficulty of identifying duplicated gallbladders and the importance of advanced imaging techniques in detecting atypical anatomical variations. The successful laparoscopic removal of both gallbladders illustrates the current capabilities of minimally invasive surgery. Postoperative recovery was uneventful, and the pathology confirmed gallstones and inflammation. LESSONS: This case emphasizes the importance of recognizing biliary anomalies such as duplicated gallbladders to avoid complications during surgery. Preoperative identification, aided by imaging, and careful surgical planning are key to managing these rare conditions. The case contributes to the growing body of knowledge about biliary system anomalies and reinforces the need for comprehensive management strategies to ensure optimal patient outcomes.

Exploring the biological behavior differences between retroperitoneal and non-retroperitoneal liposarcomas.

Background: Liposarcoma is a malignant tumor that originates from adipose tissue and can occur in any part of the body. There is currently no clear conclusion on whether there are significant differences in prognosis between liposarcoma at different anatomical locations, especially retroperitoneal liposarcoma (RLPS) and non retroperitoneal liposarcoma (NRLPS). The aim of this study is to reveal whether there are differences in prognosis between these two locations of liposarcoma, and further explore the fundamental reasons behind these differences. Methods: We conducted an in-depth investigation into the factors affecting the prognosis of patients with liposarcoma by analyzing the data from the Surveillance, Epidemiology, and End Results Program (SEER) database. Then, we used propensity score matching (PSM) to balance these prognostic factors for comparative analysis of survival between RLPS and NRLPS. In addition, by analyzing transcriptome and whole exome data from TCGA and the Japan Genotypic Phenotype Archive (JGA), we identified genes with significant expression differences and explored changes in the immune microenvironment. Result: Through analysis of RLPS and NRLPS patients in the SEER database, we observed significant prognostic differences between the two groups, with RLPS exhibiting worse prognosis (p < 0.001). Even after adjusting for confounding factors through PSM, these survival rate differences remained significant, with RLPS still showing worse prognosis (p = 0.017). Furthermore, our analysis of transcriptomic data led to the identification of 467 differentially expressed genes. Additionally, we noted significant differences in the immune microenvironment and whole exome sequencing data between the two groups. Conclusion: There are significant differences between patients with RLPS and NRLPS. Therefore, from clinical research to treatment strategies, RLPS and NRLPS should be considered as two distinct types of tumors, necessitating differentiated approaches for their study and treatment.

Prevention and treatment of rheumatoid arthritis through traditional Chinese medicine: role of the gut microbiota.

Recently, despite the increasing availability of treatments for Rheumatoid arthritis (RA), the incidence of RA and associated disability-adjusted life years have been on the rise globally in the late decades. At present, accumulating evidence has been advanced that RA is related to the gut microbiota, therefore, the therapeutic approaches for RA by regulating the gut microbiota are anticipated to become a new means of treatment. Traditional Chinese medicine (TCM) can regulate immunity, reduce inflammation and improve quality of life in various ways. Moreover, it can treat diseases by affecting the gut microbiota, which is a good way to treat RA. In this review, we mainly explore the relationship between TCM and gut microbiota regarding the perspective of treating RA. Moreover, we comprehensively summarize the roles of gut microbiota in the onset, development, progression, and prognosis of RA. Additionally, we elucidate the mechanism of TCM prevention and treatment of RA by the role of microbiota. Finally, we provide an evidence-based rationale for further investigation of microbiota-targeted intervention by TCM.
