PurposeThe aim of this study was to review our experience with splenic abscesses, with respect to the relevant aspects of splenic abscesses and treatment outcomes.Materials and MethodsWe reviewed the cases of 18 patients who had splenic abscesses and who were treated at our hospital from November 1993 to December 2008.ResultsThe most common symptom at presentation was abdominal pain in 12 patients (66.7%). The median duration from symptom onset until establishment of a diagnosis was 22 days. Streptococcus viridians was the most common pathogen (27.8%), follow by Klebsiella pneumoniae (22.2%). The mortality rate during the inpatient period and the previous 90 days was 16.6%. Three of four patients with Klebsiella pneumoniae showed a single abscess pocket. Four patients (22.2%) underwent percutaneous drainage, eight (44.5%) recieved antibiotic treatment only and six (33.3%) underwent splenectomy.ConclusionThere is no gold standard for treating splenic abscesses. Treatment should be customized for each patient.
BackgroundMost patients with distal extrahepatic cholangiocarcinoma have developed jaundice or cholangitis at the time of initial diagnosis, which can delay surgery. We aim to evaluate the actual EB-RFA ablation volume and validated the clinical feasibility of preoperative endobiliary radiofrequency ablation (EB-RFA) for resectable distal extrahepatic cholangiocarcinoma.MethodsThe medical records of patients who underwent EB-RFA from July 2016 to June 2017 at a single tertiary academic medical center were reviewed. Inclusion criteria were patients with resectable distal extrahepatic cholangiocarcinoma who required preoperative biliary decompression. Clinical outcomes of EB-RFA were reviewed retrospectively and the surgical specimens were reevaluated.ResultsOf the eight patients who required a delayed operation, preoperative EB-RFA was successfully performed without serious complications including peritonitis, hemobilia, or perforation. Although curative resection was attempted in all patients, one patient underwent open and closure due to hepatic metastasis. Seven patients underwent curative surgical resection and the histology revealed that median maximal ablation depth was 4.0 mm (range, 1–6) and median effective ablation length (histological ablation length/fluorosocopic ablation length) was 72.0% (range, 42.1–95.3).ConclusionsEB-RFA partially ablated human cancer tissue and preoperative EB-RFA might be a safe and feasible in patients with distal extrahepatic cholangiocarcinoma who require a delayed operation. Ablation of the target lesion longer than the estimated length by fluoroscopy may improve the efficacy of EB-RFA.
Abdominal wall endometriosis in a Caesarean section scar (AEC) is an infrequent type of extrapelvic endometriosis which rarely transforms into a malignant lesion. A painful mass located in the scar of a Caesarean section is a typical sign of AEC. This condition is diagnosed preoperatively using imaging modalities such as computed tomography and ultrasonography, as well as fine-needle aspiration. Although AEC has typical signs, general surgeons often misdiagnose it due to its rarity. Herein, we report our experience of AEC in a single institution.
Background/AimsRecurrence after hepatic resection is one of the most important factors impacting the prognosis and survival of patients with hepatocellular carcinoma (HCC). We identified prognostic factors affecting overall survival (OS) and disease-free survival (DFS) in patients with HCC after hepatic resection.MethodsThis study was of a retrospective cohort design, and 126 patients who underwent hepatic resection for HCC at Gachon University Gil Medical Center between January 2005 and December 2010 were enrolled. Various clinical, laboratory, and pathological data were evaluated to determine the prognostic factors affecting OS and DFS.ResultsTwo- and 4-year OS and 2- and 4-year DFS were 78.1% and 65% and 51.1% and 26.6%, respectively. In a multivariate analysis, preoperative α-fetoprotein (> 400 ng/mL), tumor size (≥ 5 cm), multiple tumors (two or more nodules), presence of portal vein invasion, modified Union for International Cancer Control (UICC) stage III/IV, and Barcelona Clinic Liver Cancer (BCLC) stage B/C were independent prognostic factors affecting a shorter OS. In the multivariate analysis, presence of microvascular invasion, modified UICC stage III/IV, and BCLC stage B/C were independent prognostic factors for a shorter DFS.ConclusionsThe presence of vascular invasion was an independent poor prognostic factor for OS and DFS in patients with HCC after hepatic resection. Thus, close postoperative surveillance for early detection of recurrence and additional treatments are urgently needed in patients with vascular invasion after hepatic resection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
