In spite of the improvement in imaging modalities and increasing recognition of biliary cystadenoma and cystadenocarcinoma, accurate preoperative diagnosis may be difficult. Complete surgical removal (liver resection or enucleation) of these lesions yields satisfying long-term results.
Surgery is the main modality in the treatment of hepatic hydatid disease. In this report, a laparoscopic surgical method is described, and the results in the first 16 cases are presented. The method involves the use of an aspirator-grinder apparatus that achieves effective evacuation of viable cyst contents with the patient benefiting from the laparoscopic approach. Cavity infection occurred in two patients and was treated conservatively. In another patient, postoperative ultrasonography revealed a thick-walled cavity containing a dense fluid. Because the patient was symptomatic, pericystectomy was performed during the sixth postoperative month. Early postoperative parameters and the early follow-up results in other patients (2-17 months) are encouraging. The method is particularly suitable for uncomplicated, early-stage cysts located in laparoscopically accessible locations.
Surgery is still the main modality in the treatment of hepatic hydatid disease. Laparoscopic methods, with their low morbidity, have gained prominence in many fields and, in some cases, have nearly replaced open surgery. In this report, a laparoscopic method for the treatment of hepatic hydatid disease is described and the results in the first six cases are presented. The method involves the use of an aspirator-grinder apparatus designed specifically for laparoscopic surgery. The postoperative courses of the patients were very comfortable and no complication related to the laparoscopic technique occurred. The method achieves evacuation of all viable cyst contents with the patient benefits of laparoscopic surgery. The apparatus practically eliminates the risk of spillage. The postoperative parameters and the early follow-up results (21-27 months) are very encouraging.
A 54-year-old woman was referred with the diagnosis of hepatic angiosarcoma, made by percutaneous biopsy under ultrasonographic guidance. Ultrasonography (US) had revealed a 48 x 42 x 35 mm mass in the right lobe. Standard biochemical tests and whole blood count had yielded normal results. At our institution, magnetic resonance imaging demonstrated a hypervascular mass in the right lobe. Alpha-fetoprotein, carcinoembryonic antigen, and carbohydrate antigen 19-9 levels were normal. Serological tests were negative for hepatitis B and C viruses. There was no evidence of metastasis. A right hepatectomy was performed. Histopathological examination confirmed the diagnosis of angiosarcoma. However, there was a suspicion of microscopically positive margins. Relaparotomy and resection of a 1-cm-thick slice of hepatic parenchyma was performed. Histopathological examination revealed necrotic tumor cells at the previous margin. The new surgical margin was tumor free. Due to the expected poor prognosis, prophylactic chemoembolization of the remnant liver (lipiodol + adriamycin + mitomycin) was performed at 3 and 7 months postoperatively. She has been alive without recurrence for 5 years and 4 months. Hepatic angiosarcoma has two distinct presentations: multiple tumors and a solitary tumor. The reported poor results largely stem from the predominance of the multiple tumors and consequent unresectability. Long-term survival is possible in solitary resectable hepatic angiosarcomas.
Background: The rate of surgical site infection (SSI) after pancreaticoduodenectomy (PD) is high and insertion of preoperative bile duct catheterization (PBDC) predispose a high risk of SSI with multidrug resistant (MDR) microorganisms. Aim: To describe the effects of PBDC and the prophylaxis in development of SSI. Methods: We conducted a retrospective study between January 01, 2010 and December 2018 including the patients with PD and total pancreatectomy. Findings: In total 214 consecutive patients were included. The PBDC was inserted to 63 (29%) patients. The rate of intraoperative bile fluid culture positivity was higher among the patients with PBDC (84% vs. 17% respectively, p < 0.001). The SSI was detected in 52 patients (24%). In multivariate analysis, the rate of SSI was found to be higher among the patients with PBDC (OR: 2.33, 95% Cl: 1.14-4.76, p = 0.02). As the etiologic agents of SSI, Pseudomonas spp. and MDR pathogens were mainly detected in PBDC group. The resistance to ampicillin-sulbactam was significantly higher in the PBDC group (87.5% vs. 25%, p = 0.012). The similar bacterial species both in bile fluid and the surgical site were detected in 11 (21%) patients with SSI. Among 8 patients (15%), antimicrobial susceptibility was the same. Only in five out of 52 (10%) patients, the SSI pathogens was susceptible to the agent that was used for surgical prophylaxis. Conclusion: Unnecessary catheterizations should be avoided. By considering the increasing prevalence of resistant bacteria as the cause of SSI, the clinicians should closely follow-up their patients for choosing the proper antimicrobials.
In this study, foreign body granuloma mimicking liver metastasis diagnosed on routine follow-up examination in a 41-year-old woman with rectal adenocarcinoma is reported. To our knowledge, this is the first study in English-language literature reporting foreign body granuloma indistinguishable from liver metastasis on radiological examination.
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.
