RESUMO

BACKGROUND: Pirfenidone (PF) is a potent antifibrotic and anti-inflammatory agent. We investigated the protective effect of PF against postoperative intra-abdominal adhesions. MATERIAL AND METHODS: Thirty male Sprague-Dawley rats were divided into three groups (n = 10 in each group). In group 1 (control), adhesion induction was performed by cecal abrasion, and no treatment was administered. In group 2 (vehicle), for 2 wk after adhesion induction, 0.4%-carboxymethylcellulose was administered by gavage. In group 3 (PF treatment), for 2 wk after adhesion induction, 500-mg/kg/d PF was administered by gavage. On the 15th postoperative day, the animals were killed, and cecal and peritoneal tissues were excised. The adhesions were graded macroscopically. The protein concentrations and mRNA expression levels of the following genes were measured in the tissues: matrix metallopeptidase-9 (MMP-9); tissue inhibitor of metalloproteinase-1 (TIMP-1); tumor necrosis factor-alpha (TNF-α); and transforming growth factor-beta 1 (TGF-ß1). The tissue samples were also evaluated histopathologically. RESULTS: Macroscopic and histopathologic evaluation showed that PF-reduced adhesion and inflammation (P < 0.001, P = 0.004, respectively). Pretreatment with PF-reduced TIMP-1, TNF-α, and TGF-ß1 protein concentrations (P < 0.001, P < 0.001, and P < 0.001, respectively) and mRNA expression levels (P = 0.030, P = 0.005, and P = 0.016, respectively) and increased MMP-9 protein concentrations (P < 0.001) and mRNA expression (P = 0.021). CONCLUSIONS: The findings of this study suggest that PF can be used as a protective agent to prevent the development of peritoneal adhesions and inflammation during the postoperative period.

RESUMO

Cholecystectomy is a common surgical procedure for various indications. Preoperative imaging is the main stay in the management of the patients. Routine and/or selective histopathological examination of the cholecystectomy materials have been discussed previously. However, incidental findings may be only observed with routine histopathological examination. Here, we report an incidental gallbladder signet cell carcinoma in a 66 years old patient. This case underlines the importance of routine histopathological examination after cholecystectomy.

RESUMO

Appendiceal malignancies are rare clinic entities. The clinical presentation of appendiceal malignancies is often atypical. Acute abdominal pain and acute appendicitis, which requires early surgical intervention, are the most common clinical presentations of appendiceal malignancies. In this case report, an adenocarcinoma of the appendix in a 64-year-old male from a nursing home has been presented. He had right lower quadrant pain for the last 5 days. On physical examination, he had significant guarding. Intravenous contrast-enhanced abdominopelvic tomography revealed no pathological features. Laparotomy under general anesthesia was scheduled. During exploration, a perforated appendicitis was observed. Formal appendectomy was performed. The patient was lost due to pneumonia and septic shock 5 days after surgical intervention. In addition, the natural history of the disease and its basic diagnostic and therapeutic aspects are discussed. Preoperative or intraoperative diagnosis may not be available for some patients. Thus, routine histopathological examination is essential for adequate diagnosis and treatment.

RESUMO

BACKGROUND: Hepatic ischemia-reperfusion (I/R) injury is a major complication in clinical practice. Previous studies suggest that statins have pleiotropic effects in addition to cholesterol-lowering effects. In this study, we aimed to investigate the hepatoprotective role of two different doses of simvastatin (SV) pretreatment in rats with experimental hepatic I/R injury. METHODS: Adult male Sprague-Dawley rats were divided into four groups (n = 7 in each group) :control, I/R, I/R with 2.5-mg/kg SV, and I/R with 5.0-mg/kg SV. Before hepatic I/R was induced, SV was injected intraperitoneally at doses of 2.5 and 5.0 mg/kg. After 45-min ischemia and a 60-min reperfusion period, the animals were euthanized, and liver tissues were excised. Tissue levels of malondialdehyde and nitric oxide, and activities of superoxide dismutase, glutathione peroxidase, and catalase were measured. Liver tissues were also evaluated histopathologically and immunohistochemically. RESULTS: Histopathologic evaluation showed that 5.0-mg/kg SV reduced hepatic damage and apoptosis. Pretreatment with 5.0-mg/kg SV reduced malondialdehyde and nitric oxide levels (P < 0.01) and increased superoxide dismutase, glutathione peroxidase, and catalase activities significantly (P < 0.001, P < 0.01) in I/R with 2.5-mg/kg SV compared with I/R group. In addition, SV decreased Kupffer cell activation, and hypoxia-inducible factor-1α and vascular endothelial growth factor protein levels. CONCLUSIONS: The results of this study suggest that 5.0-mg/kg SV pretreatment may be protective against hepatic I/R injury. This effect can be achieved by antioxidant and antiapoptotic activities.

RESUMO

Purpose Cholecystectomy is one of the most frequently performed surgeries. Although laparoscopy is considered the gold standard approach, it cannot prevent biliary injuries. Subtotal cholecystectomy has been performed mainly to prevent biliary injuries during difficult cholecystectomies. This study aimed to analyse our subtotal cholecystectomy results for difficult cholecystectomy cases and to evaluate the fenestrating and reconstituting techniques. Methods Retrospective data were collected and analysed statistically for cases that underwent subtotal cholecystectomy in a single referral centre between 2015 and 2020. Comparisons were made of the patients' age, gender, preoperative American Society of Anaesthesiologists (ASA) score, comorbidities, surgical timing, surgical procedure choice, postoperative complications, and mortality. Results The number of patients who underwent subtotal cholecystectomy was 46; 30.4% underwent emergent surgery and 69.6% underwent elective surgery. Twelve patients had subtotal fenestrating cholecystectomy and 34 had subtotal reconstituting cholecystectomy. Wound issues were noted in 17.4% of the patients, while 10.9% had temporary biliary fistulas that resolved spontaneously. Reoperation was performed in one patient due to high-output biliary drainage. Patients with postoperative complications had significantly higher co-morbid conditions (p=0.000), but surgery timing (p=0.192) and type of subtotal cholecystectomy (p=0.409) had no statistically significant effect on complications. Mortality showed a statistically significant correlation with patient comorbidities, surgery timing, and the type of procedure (p<0.05). Postoperative complications showed a statistically significant correlation with mortality (p<0.05). Conclusion Subtotal cholecystectomy prevents major biliary complications after cholecystectomy. Yet, the frequency of postoperative complications after subtotal cholecystectomy is incontrovertible. Intraoperative characteristics and the surgeon's expertise decide the optimal choice of the subtotal cholecystectomy technique.

RESUMO

BACKGROUND: Drainage of pelvic abscesses is interventional procedures that should be well planned due to organ contiguity. There are not enough publications in the literature evaluating the treatment methods of pelvic abscess drainage and comparing success rates. METHODS: In this study, 15 patients who underwent pelvic abscess drainage in our interventional radiology unit between June 2017 and December 2019 were retrospectively included. Abscess size, abscess characteristics, the method of access to abscess (transrectal, transvaginal, transgluteal), and drainage treatment procedure (needle aspiration, catheter treatment) were evaluated statistically in terms of effects on the success of treatment. RESULTS: Of the 15 patients included in the study, 6 (40%) were male and 9 (60%) were female, with a mean age of 31.6 years.In 2 of the patients treated with needle aspiration alone, the abscess collection was repeated and the second procedure was performed. In our study, the technical success was 100% and the complete clinical success was 80%. None of the patients underwent open surgery due to abscess after drainage treatment. CONCLUSION: In conclusion, endocavitary and percutaneous drainage treatments of pelvic abscesses are safe and effective treatment methods. The success of needle aspiration treatment is lower than catheter treatment and it should be considered that the abscess collection may recur.

RESUMO

BACKGROUND: Hepatic ischemia-reperfusion (HIR) is a severe condition that is seen after hepatic arterial injury and in hepatic grafts in living donor transplantation. HIR not only causes liver injury by lipid peroxidation, but also stimulates systemic and portal endotoxemia. Also, lipopolysaccharide (LPS) induces hepatic injury mediated by inducible nitric oxide synthase (iNOS). There is little knowledge on the role of specific iNOS inhibitors in prevention of HIR injury followed by LPS administration. The aim of this study on a LPS induced HIR model was to investigate the effect of aminoguanidine (AG) administration on hepatic tissue iNOS expression and lipid peroxidation when given before or after LPS. METHODS: Six groups were designed; A: Sham, B: HIR, C: HIR + AG, D: HIR + LPS, E: HIR + LPS + AG, F: HIR + AG + LPS. No substance was given to the rats in Group A and B. HIR injury was induced with vascular occlusion for 45 min and reperfusion for 45 min. Drugs were given intraperitoneally 10 min before reperfusion. Serum and tissue analysis for myeloperoxidase (MPO), and malondialdehyde (MDA), and tissue NA+/K+ adenosine 5'triphosphatases (ATPase) and tissue iNOS staining were performed. Permission for this study was obtained from the local Ethics Committee. RESULTS: The level of MPO, MDA, and iNOS staining scores in Group B were significantly higher than Group A and ATPase was lower in Group B (P < 0.05). Contrary to results in Group C, results of MPO, MDA, and iNOS staining scores of Group D was higher than Group B (P < 0.05); however, although iNOS in Group C was lower than Group B, the difference was not significant (P > 0.05). MPO and MDA levels of Groups E and F were significantly lower than Group D. Level of ATPase in Group F was significantly different from Groups D and E. iNOS scoring was low in Group F compared with Group D (P < 0.05). MDA, MPO, and iNOS levels of Group F was lower than Group E, and ATPase of Group F was higher than Group E (P < 0.05). CONCLUSIONS: The results of this study in a LPS induced HIR model showed that LPS after HIR aggravated HIR injury by increasing neutrophil activation and lipid peroxidation both in serum and liver tissue and iNOS in liver, and depleting energy in liver. AG, a selective iNOS inhibitor, ameliorated the negative effects of endotoxemia induced by LPS after HIR; however, energy depletion and iNOS expression in liver tissue were attenuated only when AG was administered prior to LPS. The findings of this study supported the hypothesis that LPS after HIR would aggravate HIR injury and AG would ameliorate this aggravated injury.

RESUMO

Combined duplication of the colon and vermiform appendix is one of the rare congenital anomalities of the alimentary tract. Only a few cases have been reported in the adult population. A 28-year-old man presented to the clinic with a mass in the right flank. Imaging showed only a hydronephrotic atrophic kidney. The final diagnosis was only available at exploration. Combined duplication of the tubular colon and vermiform appendix was confirmed histopathologically. The patient was treated with nephrectomy and complete resection of the duplicated colon and vermiform appendix. The patient recovered uneventfully, and has done well for the past year. This is believed to be one of the first reports of combined duplication of the tubular colon and vermiform appendix as a cause of hydronephrotic atrophic kidney in an adult patient.

RESUMO

INTRODUCTION: The aim of the present study was to evaluate the role of erythropoietin (EPO) in liver and renal injury following hemorrhagic shock (HS) after inhibition of tyrosine kinase activity in rats.. METHODS: Forty-eight Sprague-Dawley rats were assigned to six groups: (I) HS alone; (II) HS followed by retransfusion; (III) EPO and genistein followed by HS; (IV) EPO and genistein followed by HS, followed by retransfusion; (V) HS followed by EPO and genistein; and (VI) HS followed by EPO and genistein, followed by retransfusion. HS was induced for 60 minutes after withdrawal of 30% of the calculated total blood volume of each rat from the left femoral artery. Blood and tissue samples (from the kidney and liver) were obtained 60 minutes after HS in Group I, III, and V; blood and tissue samples were obtained 60 minutes after retransfusion in Group II, IV, and VI. In Group III and IV, EPO was given 60 minutes before HS, and genistein 30 minutes before HS. In Group V and VI, EPO and genistein were given 30 minutes after HS. RESULTS: Liver and renal injury were significantly attenuated with EPO and genistein administration. CONCLUSION: These results suggest that EPO is effective in attenuating liver and renal injury in HS, even with inhibition of tyrosine kinase activity with genistein.

RESUMO

Fournier's gangrene (FG) is a rare, rapidly progressive, fulminant form of necrotizing fasciitis of the genital, perianal and perineal regions. Several factors have been reported to contribute to the clinical outcomes. The primary aims of this study were to examine the clinical features of patients with FG and evaluate the predictivity of the Fournier's Gangrene Severity Index (FGSI) score on the outcomes. We carried out a collective retrospective chart review of patients diagnosed and treated for FG in three reference centers between January 1995 and July 2007. Seventy-two patients with FG with were included to the study. Data were collected on medical history, symptoms, physical examination findings, admission and final laboratory tests, timing and extent of surgical debridement and antibiotic therapy. Perianal and perirectal abscess, scrotal abscess and urethral stenosis were the leading etiological factors. Diabetes mellitus was the predominant risk factor. Etiological factors and risk factors did not significantly contribute to survival or mortality, and duration of the symptoms was significantly longer in the non-survivor's group (P < 0.05). The FGSI scores were higher in the non-survivor's group. Regression analysis showed a FGSIS score of 10.5 as the cut-off to the outcome. Based on these results, we conclude that a patient's metabolic status and the extent of disease at presentation are the most important factors determining the prognosis of FG. The FGSI score may be considered as an objective and simple tool to predict the outcome in the patient with FG and should be used in further studies of FG patient series for comparison purposes.

RESUMO

BACKGROUND: The main cause of acute cholecystitis (AC) is gallstones, and the incidence of gallstones in elderly patients is high. METHODS: In this study, we aimed to investigate the efficacy of percutaneous cholecystostomy (PC) before early cholecystectomy in geriatric patients with AC. This retrospective study included 85 patients undergoing laparoscopic or conventional cholecystectomy during early stage of calculous AC. RESULTS: All patients were over 65 years old and were divided into two groups: Group I, PC plus early cholecystectomy and Group II, only cholecystectomy without PC. Data on age, sex, status of PC before surgery, postoperative complications, postoperative mortality, surgical method, and postoperative hospitalization duration were recorded in our study. The average age in the groups I and II was 75.7±7.5 and 73.7±7.2 years, respectively, indicating insignificant difference (p=0.223). Although postoperative complication rate was two fold in the non-PC group, the PC plus cholecystectomy group has a few complications (p=0.032). Postoperative mortality was evidently lower in patients who first underwent PC and followed by cholecystectomy (p=0.017). The average hospitalization duration in groups I and II were 5.6±2.4 days and 11.2±7.7 days, respectively (p<0.001). CONCLUSION: Urgent laparoscopic cholecystectomy is still the best surgical treatment modality for calculous AC. Further, our study results showed that in geriatric patients, bridge treatment, such as PC, can be useful for reducing postoperative complication rates.

RESUMO

Obstructive jaundice (OJ) is a severe condition that leads to several complications. One of the important problems in OJ is the increased incidence of endotoxemia, which is the result of bacterial translocation (BT) and defective host immune response. Lipid peroxidation (LP) is an important problem in OJ and sepsis in which nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) activity are increased and antioxidative activity is decreased. Formation of peroxynitrite (ONOO(-)) anion leads to cellular damage and apoptosis. In this experimental study, we explore the effect of specific iNOS inhibitor aminoguanidine (AG) on blood and tissue (liver and renal) LP and iNOS levels in jaundiced rats with endotoxemia induced with lipopolysaccharide (LPS). Rats were randomized into six groups; group A, sham; group B, obstructive jaundice (OJ); group C, OJ + LPS; group D, OJ + AG; group E, OJ + LPS + AG; group F, OJ + AG + LPS. Serum malondialdehyde (MDA) and serum myeloperoxidase (MPO) activity and liver and renal tissue MDA, MPO, and Na(+)/K(+)-ATPase activity levels were detected in biochemical methods. Liver and renal tissue iNOS levels were examined immunohistopathologically. Serum and tissue MDA and MPO levels and tissue iNOS expression were increased significantly in groups B, C, and E, while tissue ATPase levels were decreased significantly in the same groups. In the group treated with AG (group D), serum and tissue MDA and MPO levels and tissue iNOS expression were decreased while tissue ATPase levels were increased significantly. In group F, if AG was administrated before LPS, we observed that serum and tissue MDA and MPO levels and tissue iNOS expression were decreased while tissue ATPase levels were increased significantly. Thus, our study showed that AG had a protective effect when it was administrated before LPS, but it failed to prevent tissue iNOS expression and LP if there was established endotoxemia in OJ.

RESUMO

Introduction. We report the management of a septic Open Abdomen (OA) patient by the help of negative pressure therapy (NPT) and abdominal reapproximation anchor (ABRA) system in pregnant woman with spontaneous jejunal perforation after emergent cesarean section (C/S) with confounding factor of mild acute pancreatitis (AP). Presentation of Case. A 29-year-old and 34-week pregnant woman with AP underwent C/S. She was arrested after anesthesia induction and responded to cardiopulmonary resuscitation (CPR). There were only ash-colored serosanguinous fluid within abdomen during C/S. After C/S, she was transferred to intensive care unit (ICU) with vasopressor support. On postoperative 1st day, she underwent reoperation due to fecal fluid coming near the drainage. Leakage point could not be identified exactly and operation had to be deliberately abbreviated due to hemodynamic instability. NPT was applied. Two days later source control was provided by conversion of enteroatmospheric fistula (EAF) to jejunostomy. ABRA was added and OA was closed. No hernia developed at 10-month follow-up period. Conclusion. NPT application in septic OA patient may gain time to patient until adequate source control could be achieved. Using ABRA in conjunction with NPT increases the fascial closure rate in infected OA patient.

RESUMO

INTRODUCTION: Oxidative stress plays an important role in the pathogenesis of malign diseases. Prolidase is a member of the matrix metalloproteinase family, plays a major role in collagen metabolism, cell growth, and matrix remodeling. Elevated serum prolidase activity have beendemonstrated in several types of carcinoma. The aim of this study is to investigate the serum prolidase activity, total oxidant status (TOS), total antioxidant status (TAS) and to evaluate their relationship with tumor stage, lymph node metastasis, and tumor size in patients with breast carcinoma. METHODS: Thirty-five patients with breast carcinoma and forty healthy controls were enrolled to this study.Serum TAS, TOS levels, and prolidase activities were measured and oxidative stress indices (OSI) were calculated. RESULTS: TOS, OSI levels and prolidase activities were significantly higher in the patients with breast carcinoma compared to the control group (P < 0.001, P < 0.001, P = 0.002, respectively).TAS levels were significantly lower in the in the patients with breast carcinoma compared to the control group (P = 0.016).Positive correlations were found between prolidase activity, TOS, OSI levels and tumor stage, lymph node metastasis, and tumor size. A negative correlation was found between TAS levels and tumor size,hovewer there were no correlationsbetween tas levels and stage of the tumor,as well as lymph node infiltration. CONCLUSION: We conclude that elevatedserum prolidase activity and oxidative stress may be associated with breast carcinoma. Increased serum prolidase activity may be related to stage and prognosis of breast carcinoma. KEY WORDS: Breast carcinoma, Oxidative stress, Proline dipeptidase.

RESUMO

INTRODUCTION: Intestinal malrotation refers to the partial or complete failure of rotation of midgut around the superior mesenteric vessels in embryonic life. Arrested midgut rotation results due to narrow-based mesentery and increases the risk of twisting midgut and subsequent obstruction and necrosis. PRESENTATION OF CASE: 40 years old female patient admitted to emergency service with acute abdomen and computerized tomography scan showed dilated large and small intestine segments with air-fluid levels and twisted mesentery around superior mesenteric artery and vein indicating "whirpool sign". DISCUSSION: Malrotation in adults is a rare cause of midgut volvulus as though it should be considered in differential diagnosis in patients presented with acute abdomen and intestinal ischemia. Even though clinical symptoms are obscure, adult patients usually present with vomiting and recurrent abdominal pain due to chronic partial obstruction. Contrast enhanced radiograph has been shown to be the most accurate method. Typical radiological signs are corkscrew sign, which is caused by the dilatation of various duodenal segments at different levels and the relocation of duodenojejunal junction due to jejunum folding. As malrotation commonly causes intestinal obstruction, patients deserve an elective laparotomy. CONCLUSION: Malrotation should be considered in differential diagnosis in patients presented with acute abdomen and intestinal ischemia. Surgical intervention should be prompt to limit morbidity and mortality.

RESUMO

BACKGROUND: We aimed to investigate the relationship between the neutrophil to lymphocyte ratio (NLR) and postoperative length of hospital stay. In addition, the impact of radiological and histopathological findings on hospital stay was also evaluated. METHOD: This is a retrospective study. One hundred three patients with appendicitis were in-cluded. The diagnosis was confirmed by computed tomography (CT), ultrasonography and histopathological examination. Correlations between the length of hospital stay and age, gender, NLR, c-reactive peptide levels (CRP), the appendix diameter on CT or ultrasonogra-phy, appendix localisation and pathology reports were evaluated. RESULTS: The length of hospital stay was not related to age or gender. The length of hospital stay after appendectomy was correlated with appendix diameter on CT and phlegmonous appendicitis, but it was not associated with NLR, CRP levels or the appendix diameter on ultrasonography. CONCLUSION: To our knowledge, this is the first comprehensive study to evaluate the associa-tion between NLR levels and the length of hospital stay in patients with acute appendicitis. The NLR was not found to be associated with the length of hospital stay. The appendix di-ameter on CT and appendix pathology reports were correlated with the length of postopera-tive hospital stay in appendectomy patients.

RESUMO

The aim of our study was to evaluate the relationship between neutrophil to lymphocyte ratio (NLR) and adenoma size in parathyroidectomized patients who underwent a parathyroidectomy. The neutrophil to lymphocyte ratio has recently become popular as a biomarker for malignant diseases or for estimating tumor size preoperatively. This study aimed to estimate the relationship between adenoma size and NLR. Furthermore, we assessed whether a higher level of NLR is correlated with the presence of parathyroid carcinoma. A retrospective chart review was performed for patients with parathyroid adenoma who underwent parathyroidectomy between January 2012 and August 2014. Data related to age, sex, NLR, parathyroid hormone level (PTH), preoperative calcium, phosphorus, adenoma size, and pathology reports were collected. The neutrophil to lymphocyte ratio was significantly correlated with calcium levels, PTH levels, parathyroid adenoma size, and the presence of cancer. However, there was no correlation between NLR and age, sex, and phosphorus levels. This study is the first to document a positive correlation between NLR and parathyroid adenoma size, as well as the presence of cancer, in patients who underwent surgery as a result of primary hyperparathyroidism.

RESUMO

Right lower quadrant pain is one of the most common symptoms of the emergency patients. For accurate diagnosis and treatment; the patients must be questioned and examined very well. Also accompanying conditions due to right lower quadrant pain may be noticed. In this case presentation, we discussed a patient who was presented with right lower quadrant pain and cervical dystonia. By limiting the usage of metoclopramide the patient was followed seamlessly. In this case presentation we want to accentuate that a patient who with abdominal pain may be presented with rare symptoms such of dystonia. In such conditions a detailed anamnesis and physical examination are the first steps of the evaluation to prevent potential hazardous outcomes. In particular, a surgeon must be always carefully while taking history and examining the patient.

RESUMO

AbstractObjective: This study aimed to determine the relationship between MPV and thyroid malignancy by comparing patients who underwent surgery for benign or malignant thyroid diseases. BACKGROUND: Mean platelet volume (MPV) is a useful early indicator of platelet activation. Platelets differ in terms of functional activity and size. Large platelets are relatively new, more reactive and produce more thrombogenic factors. Therefore, in conditions that involve increased platelet activation, an increase in the proportion of young platelets and MPV is expected. PATIENTS AND METHODS: This study involved 146 patients who underwent total thyroidectomy because of benign (99 patients) or malignant (47 patients) diseases of the thyroid. Data on age, sex, MPV, white blood cell (WBC) count, hemoglobin level and platelet count were collected retrospectively. RESULTS: MPV was significantly higher in patients with malignant thyroid diseases than in those with benign thyroid diseases. Age, sex, hemoglobin level, WBC count and platelet count did not significantly differ between the two groups. CONCLUSION: MPV was significantly higher in patients with thyroid malignancies than in patients with benign thyroid diseases. We propose that MPV might be an important predictive factor for thyroid malignancies. Further prospective studies with a larger number of patients in high-volume endocrine surgery centers are required to confirm our findings.

RESUMO

INTRODUCTION: Alveolar echinococceal disease of the liver is rare. Echinococcus multilocularis is responsible for the development of the related clinical conditions. Advanced disease may result with serious complications such as end stage liver disease and Budd-Chiari syndrome. PRESENTATION OF CASE: In this presentation, a 28 years-old woman who was a case with advanced alveolar echinococcosis complicated with a Budd-Chiari syndrome and was performed successful living donor liver transplantation, has been demonstrated with clinical and radiological images. DISCUSSION: Initially there may be no clinical evidence of the disease in humans for years. Severity and fatality are the significant characteristics of the natural history. Extension to the surrounding tissues and metastasis of the parasitic mass may be observed. Prevention is essential in disease control. Serologic assay may identify the parasite. However, early diagnosis is rare. Staging is based on radiologic imaging. Some patients with advanced disease may require surgery. Hepatic resection and liver transplantation are accepted procedures in selected patients. CONCLUSION: The importance of early diagnosis to prevent advanced complications such as development of Budd-Chiari syndrome and metastasis has been underlined.
