Laparoscopic repeat hepatectomy versus conventional open repeat hepatectomy for recurrent hepatocellular carcinoma: A systematic review and meta-analysis.

Background: Repeat hepatectomy has been proven to be an effective treatment in patients with recurrent hepatocellular carcinoma (RHCC). However, for RHCC, it is still controversial whether laparoscopic hepatectomy is superior to conventional ones. The present meta-analysis was carried out to investigate the safety and overall effect of laparoscopic repeat hepatectomy (LRH) to open repeat hepatectomy (ORH) for patients with RHCC. Methods: A meta-analysis was registered at PROSPERO, and the registration number is CRD42021257569. PubMed, Web of Science, and EMBASE were searched based on a defined search strategy to identify eligible studies before 25 April 2022. Data on operative times, bleeding volume, overall complications, 90-day mortality, blood transfusion, length of stay, overall survival rate, and long-term recurrence-free survival rate were subjected to meta-analysis. Results: Overall, we identified nine studies of LRH versus ORH enrolling a total of 945 patients (460 and 485 underwent LRH and ORH, respectively). The present meta-analysis revealed non-significant differences in operative time, blood transfusion, overall complications, 90-day mortality, 3-year overall survival rate, 5-year overall survival rate, and long-term recurrence-free survival rate between the two groups. Alternatively, comparing LRH with ORH, LRH has less bleeding volume (p < 0.001) and a shorter length of stay (p = 0.005). Conclusion: LRH is a feasible and effective treatment strategy for RHCC.

An ingested metallic wire migrating from stomach to pancreas treated by laparoscopic surgery: A case report.

Introduction: Foreign bodies inside the pancreas are rare and usually occur after the ingestion of sharp objects such as a fish bone, a sewing needle, or a toothpick. Furthermore, an ingested metallic wire migrating from stomach to pancreas is very rare. Case Presentation: We report a 36-year-old woman who was admitted to our hospital with "3-day history of dull progressive epigastric pain." Computed tomography of the abdomen revealed a linear, high-density body between the stomach wall and the pancreas. During the operation, a linear, hard, metallic wire was found in the adhesive tissue between the gastric antrum and the pancreatic body. The operation was uneventful, and the patient recovered well. Conclusion: The case of a foreign body inside the pancreas caused by a metallic wire is very rare. Radiological examinations play a vital role in the diagnosis of metallic wire ingestion. Metallic wire ingestion can be treated with laparoscopic surgery, both technically and safely.

Spontaneous internal hemorrhage of a giant hepatic hemangioma: A case report.

RATIONALE: Hepatic hemangioma, a benign liver tumor, can rarely spontaneously rupture and hemorrhage, which is then associated with significant mortality. The diagnosis of internal hemorrhage is challenging and the management is disputed. PATIENT CONCERNS: We describe the case of a 52-year-old female patient with chief complaints of fever and anemia, with no history of recent trauma. DIAGNOSES: Ultrasound suggested the possibility of a liver abscess and computed tomography (CT) examination revealed a giant space occupying lesion (SOL) (approximately 16 cm) in the right hepatic lobe, indicating a hepatic tumor or abscess. The patient did not respond to antibiotics and blood transfusion. Liver needle biopsy revealed blood clots suggestive of intratumoral hemorrhage, possibly of a hepatic hemangioma. INTERVENTIONS: Interventional radiologic approach revealed active bleeding at the phrenic artery that supplied the liver SOL. Thus, embolization was performed and re-angiography showed no active bleeding from the embolized vessel. The patient became afebrile, but fever recurred the next day. Hence, an exploratory open right hemihepatectomy was undertaken and the intraoperative frozen biopsy confirmed hepatic hemangioma with internal hemorrhage, but malignancy could not be excluded for some focal tissues. Postoperative pathology report confirmed the diagnosis of hepatic hemangioma with internal hemorrhage and excluded malignancy. OUTCOMES: The fever subsided and the patient was discharged in good health. A follow-up CT performed three months, postoperatively, indicated compensatory growth of the left hepatic lobe. LESSONS: This case demonstrates that the diagnosis of hepatic hemangioma with internal hemorrhage can be confirmed by needle biopsy and surgical resection is the optimal treatment for such a lesion.

Radiofrequency-Assisted Partial Splenectomy Plus Splenopexy--A Modified Surgical Procedure for Wandering Spleen: A Case Report.

Wandering spleen is an extremely rare clinical condition characterized by abnormal anatomical position of the spleen. Up to now, its etiology remains unknown, and the best surgical procedure is still an area to explore in the future. In this article, we present the case of a 24-year-old woman with wandering spleen combined with congenital heart disease and pigeon chest. Based on the clinical features and our experiences of radiofrequency ablation for preservation of the spleen in traumatic spleen rupture, we successfully performed a modified splenectomy and splenopexy method. Since the operation, the organ has remained in place with good perfusion and function.

Significance of MD-2 and MD-2B expression in rat liver during acute cholangitis.

AIM: To investigate the expression of myeloid differentiation protein-2 (MD-2), MD-2B (a splicing isoform of MD-2 that can block Toll-like receptor 4 (TLR4)/MD-2 LPS-mediated signal transduction) and TLR4 in the liver of acute cholangitis rats. METHODS: Male Sprague-Dawley rats (SPF level) were randomly divided into four groups: (A) sham-operated group; (B) simple common bile duct ligation group; (C) acute cholangitis group; and (D) acute cholangitis anti-TLR4 intervention group (n = 25 per group). Rat liver tissue samples were used to detect TLR4, MD-2 and MD-2B mRNA expression by fluorescence quantitative PCR in parallel with pathological changes. RESULTS: In acute cholangitis, liver TLR4 and MD-2 mRNA expression levels at 6, 12, 24, 48 and 72 h were gradually up-regulated but MD-2B mRNA expression gradually down-regulated (P < 0.05). After TLR4 antibody treatment, TLR4 and MD-2 mRNA expression were lower compared with the acute cholangitis group (P < 0.05). However, MD-2B mRNA expression was higher than in the acute cholangitis group (P < 0.05). MD-2 and TLR4 mRNA expressions were positively correlated (r = 0.94981, P < 0.05) and MD-2B mRNA expression was negatively correlated with MD-2 and TLR4 mRNA (r = -0.89031, -0.88997, P < 0.05). CONCLUSION: In acute cholangitis, MD-2 plays an important role in the process of TLR4- mediated inflammatory response to liver injury while MD-2B plays a negative regulatory role.
