A Rare Case of Isolated Hepatocellular Carcinoma Metastasis in Left Mandibular Region in a Patient with Hepatitis C Virus Liver Cirrhosis Diagnosed after the Onset of COVID-19 Infection. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1992. [PMID: 38004041 PMCID: PMC10673151 DOI: 10.3390/medicina59111992] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Revised: 11/03/2023] [Accepted: 11/08/2023] [Indexed: 11/26/2023]
Abstract
Background and Objectives: Hepatocellular carcinoma (HCC) most frequently metastasizes in the lungs, abdominal lymph nodes and adrenal glands. Metastatic spread to the head and neck area is extremely rare. In the presented case, an uncommon site of solitary metastatic spread of HCC to the mandible confirmed after the core biopsy of the lesion is reported. There have been only about 80 cases of mandibular HCC metastases described in the literature to date. We contribute our experience to the pool of data. Case presentation: A 65-year-old female with HCV-related liver cirrhosis was diagnosed with an HCC that was successfully treated with liver resection. Subsequently, the patient had developed COVID-19 disease, which was associated with a painless swelling in the left jaw. A neck MDCT scan demonstrated an osteolytic soft-tissue mass in the left mandible, with the characteristics consistent for the metastasis of HCC. In order to confirm the diagnosis, a core biopsy of the mandibular mass was performed. The pathohistological evaluation confirmed the presence of a metastatic HCC in the mandible. No other sites of disease dissemination were identified in extensive MDCT scans. Despite considering various treatments, including symptomatic and palliative, the patient's overall prognosis remained poor. Conclusions: Isolated metastases of HCC to the orofacial region are extremely rare; however, it should be considered in patients with known risk factors for HCC development. Early diagnosis is critical, and clinicians should consider this possibility of HCC spread when assessing patients with orofacial swelling, among those patients with risk factors for HCC. The overall prognosis for such patients remains poor, emphasizing the challenges in managing these cases.

Abstract
Abstract
Nischarin is a scaffolding protein involved in the regulation of cell cytoskeletal organization and metabolic homeostasis. In breast and ovarian cancers, nischarin has been demonstrated to have tumor suppressive functions. We have found that nischarin was expressed in both the epithelial and stromal compartments of the PDAC patient tissue, in cancer cell lines and patient-derived stellate cells. Of interest, nischarin is a functional imidazoline 1 receptor for which there are several FDA-approved agonists used for treatment of hypertension. The aim of this study was to examine the effects of nischarin agonists on PDAC cancer cells and stellate cells, separately and in co-culture and determine the potential for their repurposing in treatment of PDAC. mRNA sequencing revealed that cancer cell treatment with nischarin agonist rilmenidine induced transcriptional changes associated with regulation of cell adhesion, EMT and vesicular transport. In vitro, rilmenidine treatment of cancer cells decreased their migration and invasion potential and treatment of stellate cells decreased the αSMA-positive fraction. Treatment of cancer cell-stellate cell co-cultures decreased the production of pro-inflammatory cytokines IL-6, IL-8 and CCL-2, known drivers of the metastatic progression. Ultimately, rilmenidine treatment decreased PDAC cell invasion in Tg(fli1: EGFP) zebrafish model. Taken together, nischarin agonist rilmenidine has a potential for limiting the processes involved in PDAC metastatic cascade and may be a good candidate for drug repurposing.

Effect of Percutaneous Biliary Drainage on Enzyme Activity of Serum Matrix Metalloproteinase-9 in Patients with Malignant Hilar Obstructive Hyperbilirubinemia. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59020336. [PMID: 36837539 PMCID: PMC9958900 DOI: 10.3390/medicina59020336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/27/2022] [Revised: 01/29/2023] [Accepted: 02/05/2023] [Indexed: 02/15/2023]
Abstract
Background and Objectives. Cholestasis activates complex mechanisms of liver injury and as a result has an increased production of matrix metalloproteinases (MMP). Depending on the stage of liver disease, different matrix metalloproteinases expressions have been detected and could serve as indirect biomarkers as well as therapeutic targets. MMP-9 proteolytic activity has a proven role in both liver regeneration and neoplastic cell invasion in various malignancies. The purpose of this prospective cohort study was to evaluate the effect of external biliary drainage on enzyme activity of MMP-9 in the serum of patients with malignant hilar biliary obstruction. Materials and Methods. Between November 2020 and April 2021, 45 patients with malignant hilar biliary obstruction underwent percutaneous biliary drainage following determination of serum MMP-9 enzyme activity (before treatment and 4 weeks after the treatment) by gelatin zymography. Results. MMP-9 values decreased statistically significantly 4 weeks after percutaneous biliary drainage (p = 0.028) as well as the value of total bilirubin (p < 0.001), values of direct bilirubin (p < 0.001), aspartate aminotransferase (AST) (p < 0.001), alanine transaminase (ALT) (p < 0.001), and gamma-glutamyl transferase (GGT) (p < 0.001). Conclusions. In patients with malignant hilar biliary obstruction treated by external percutaneous biliary drainage for cholestasis resolution, a significant reduction in MMP-9 serum values was noted 4 weeks after the treatment.

Prognostic Nutritional Index (PNI) and Neutrophil to Lymphocyte Ratio (NLR) as Predictors of Short-Term Survival in Patients with Advanced Malignant Biliary Obstruction Treated with Percutaneous Transhepatic Biliary Drainage. J Clin Med 2022; 11:jcm11237055. [PMID: 36498630 PMCID: PMC9741251 DOI: 10.3390/jcm11237055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Revised: 11/16/2022] [Accepted: 11/25/2022] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Effective biliary tree decompression plays a central role in the palliation of malignant biliary obstruction (MBO). When endoscopic drainage is unfeasible or unsuccessful, percutaneous transhepatic biliary drainage (PTBD) is the method of choice and preferred treatment approach in advanced hilar MBO. The prognostic nutritional index (PNI) reflects the patient's immunonutritional status, while the neutrophil to lymphocyte ratio (NLR) reflects the patient's inflammation status. The aim of the present study was to evaluate the prognostic value of preprocedural PNI and NLR on short-term survival in the advanced stage MBO population threatened with PTBD and to characterize the differences in immunonutritional and inflammatory status between 60-day survivors and non-survivors, as well as analyze other variables influencing short-term survival. METHODS This single-center retrospective study was conducted on patients undergoing palliative PTBD caused by MBO as a definitive therapeutic treatment between March 2020 and February 2022. After the procedure, patients were followed until the end of August 2022. RESULTS A total of 136 patients with malignant biliary obstruction were included in the study. Based on receiver operating characteristic (ROC) curve analysis, optimal cut off-values for NLR (3) and PNI (36.7) were determined. In univariate regression analysis, age, absolute neutrophil count, albumin level, NLR ≤ 3, and PNI ≥ 36.7 were significant predictors of 60-day survival. Level of obstruction and PNI ≥ 36.7 were statistically significant independent predictors of 60-day survival in a multivariate regression model. Using PNI ≥ 36.7 as a significant coefficient from the multivariate regression model with the addition of NLR ≤ 3 from univariate analysis, a 60-day survival score was developed. CONCLUSIONS PNI and NLR are easy to calculate from routine blood analysis, which is regularly conducted for cancer patients. As such, they represent easily available, highly reproducible, and inexpensive tests capable of expressing the severity of systemic inflammatory responses in patients with cancer. Our study highlights that preprocedural PNI and NLR values provide predictors of short-term survival in patients with MBO treated with palliative PTBD. In addition, the proposed 60-day survival score can contribute to better selection of future candidates for PTBD and recognition of high-risk patients with expected poor outcomes.

Abstract
BACKGROUND Gallbladder cancer (GBC) is an aggressive, uncommon malignancy, with variation in operative approaches adopted across centres and few large-scale studies to guide practice. We aimed to identify the extent of heterogeneity in GBC internationally to better inform the need for future multicentre studies. METHODS A 34-question online survey was disseminated to members of the European-African Hepatopancreatobiliary Association (EAHPBA), American Hepatopancreatobiliary Association (AHPBA) and Asia-Pacific Hepatopancreatobiliary Association (A-PHPBA) regarding practices around diagnostic workup, operative approach, utilization of neoadjuvant and adjuvant therapies and surveillance strategies. RESULTS Two hundred and three surgeons responded from 51 countries. High liver resection volume units (>50 resections/year) organised HPB multidisciplinary team discussion of GBCs more commonly than those with low volumes (p < 0.0001). Management practices exhibited areas of heterogeneity, particularly around operative extent. Contrary to consensus guidelines, anatomical liver resections were favoured over non-anatomical resections for T3 tumours and above, lymphadenectomy extent was lower than recommended, and a minority of respondents still routinely excised the common bile duct or port sites. CONCLUSION Our findings suggest some similarities in the management of GBC internationally, but also specific areas of practice which differed from published guidelines. Transcontinental collaborative studies on GBC are necessary to establish evidence-based practice to minimise variation and optimise outcomes.

Abstract
Aim
To investigate short and long-term outcome after the open preperitoneal flat mesh technique (OPPFMT) for umbilical, epigastric, spigelian, small incisional and “port-site” hernia performed as a day case procedure.
Materials and Methods
We retrospectively analyzed records of patients who underwent OPFMT for umbilical, epigastric, Spigelian, small incisional and “port-site” hernia. All patients were operated under local anesthesia in ambulatory settings. The operative technique is as follows: polypropylene flat mesh exceeding the size of the hernia defect for 2–3 cm in all directions is placed into a pre-peritoneal position above the intrabdominaly repositioned hernia sac (mesh is placed into hernia sac) and fixed by at least 8 transfascial “U” sutures.
Results
In the period from January 2004 to April 2022, 531 patients with ventral hernias (272 with umbilical, 155 with epigastric, 69 with small incisional, 17 with “port site” and 18 with Spigelian hernia) underwent surgery. During the median follow-up of 44 months, 8 (1,5%) hematomas, 2 (0,4%) seromas, 2 (0,4%), superfitial wound infections, 8 (1,5%) mesh infections and 24 (4,6%) recurrences occurred.
Conclusion
Management of epigastric, umbilical, spigelian and small incisional hernia with OPFMT under local anesthesia as a day case procedure is a safe and associated with favorable long-term outcome.

Abstract
Abstract
Aim
To present our strategy for surgical treatment of patients with giant inguinoscrotal hernia whose hernia defect is ≥10 cm or who have a loss of domain.
Material and methods
Between January 2006 - January 2022, 21 consecutive patients with giant inguinoscrotal hernia and high risk of postoperative intra-abdominal hypertension were managed. The hernia was repaired in the following manner: modified Rives technique performed through direct inguinal approach in 10 patients; additional procedures were needed to reduce the volume of organs returned to the abdomen in four patients; the primary abdominal cavity was enlarged by various components separation techniques with or without mesh hernioplasty in seven patients.
Results
The hernia defect size was in range 7–17 cm. In three patients the contents of the hernia sac accounted for more than 50% of the intestines: entire large bowel without the rectum, ileum, jejunum except proximal 15 cm and greater omentum). Postoperative complications occurred in eight patients were: scrotal hematoma, deep mesh infection, seroma and hydrocele. There were three postoperative deaths: 12 hours, 17 and 42 days after the surgery because ischemic enteritis, cerebrovascular stroke and heart failure, respectively.
Conclusion
Our strategy consisting of modified Rives technique performed through direct inguinal approach with or without additional procedures to reduce the volume of organs returned to the abdomen or to enlarge the primary abdominal cavity can be a good solution for giant inguinoscrotal hernias. Procedure is followed by the risk of deadly complications and requires trained team in intesive care unit.

Abstract
Abstract
Aim
To present a concept combining three modifications of the component separation technique (CST) in one procedure as an original solution for the management of complex subcostal abdominal wall defect.
Material and Methods
Between January 2010 and January 2022, seven patients with complex subcostal hernia defects compromised by infection, radiation, or chemotherapy underwent surgery in which three modifications of CST were combined into one procedure. Major complex subcostal hernia was defined by either width or length of the defect being greater than 10 cm. The following were the stages of the operative technique: (a) the “method of wide myofascial release” at the side of the hernia defect; (b) “openbook variation” of the component separation technique at the opposite side of the hernia defect; (c) a modified component separation technique for closure of midline abdominal wall hernias in the presence of enterostomies; (d) suturing of the myofascial flaps to each other to cover the defect; and (e) repair augmentation with an absorbable mesh in the onlay position.
Results
The median (range) length and width of the complex subcostal hernias were 15 cm (10–19) and 15 cm (8–24), respectively. The overall morbidity rate was 57.1% (wound infection, seroma and skin necrosis). There was no hernia recurrence during the median follow-up time of 19 (range 3–84) months.
Conclusion
The operative technique integrating three modifications of CST in one procedure with onlay absorbable mesh reinforcement is a feasible solution for the management of complex subcostal abdominal wall defect.

Abstract
Background Horseshoe kidney is a well-known congenital anomaly and the most common anomaly of the upper urinary tract. This condition is rarely associated with anomalous inferior vena cava (IVC). Polycystic horseshoe kidney is a very rare occurrence and however IVC anomalies common with polycistic disease are an increasingly recognized risk factor for iliofemoral deep venous thrombosis. Method We present a case of 75-year-old patient with recurrent deep vein thrombosis (DVT) of right leg as a result of compression of large horseshoe kidney cysts in double inferior vena cava. Results Large renal cyst were successful treated percutaneously punctured for the relief of compression and received injection of acidic solutions of 95% ethanol under ultrasound guidance for prevention against re-accumulation of cyst fluid. Conclusion Percutaneous aspiration with ultrasound guidance with injection of sclerosing solutions as a relatively simple procedure and can be the method of choice for treatment of renal cysts. Also, any recurrent deep vein thrombosis on lower extremity requires additional evaluation in the form of an ultrasound or multidetector computed tomography examination of the abdomen.

Abstract
BACKGROUND The aims of this study were to present the concept of original technique in the management of major incisional subcostal hernias and to evaluate short- and long-term outcome. METHOD Between January 2010 and January 2020, 280 patients underwent hernia repair surgery for incisional lateral abdominal hernia at Clinic for Digestive Surgery, Clinical Center of Serbia. Among them, 37 patients underwent the modified sublay technique for major incisional subcostal hernia with minimal hernia defect surface of 100 cm2 or greater or minimal hernia defect width or height of 10 cm or greater. The operative techniques are as follows: retromuscular dissection of rectus muscle from posterior sheath on the both sides of hernia defect, external oblique muscle dissection from internal oblique muscle in a circle around hernia defect at the side of the hernia defect, complete reconstruction of the posterior myofascial layer, large heavyweight polypropylene mesh placement in a sublay position, and complete or partial reconstruction of anterior myofascial layer. RESULTS A median (range) hernia defect surface was 150 (100-500) cm2. A median operative time was 130 (90-330) minutes. The morbidity rate was 18.9%. A median (range) postoperative hospital stay was 7 (2-24) days. After the median follow-up of 50 (1-108) months, 2 patients (5.4%) developed recurrent hernia. CONCLUSIONS The modified sublay technique using large heavyweight polypropylene mesh provides good results in the management of major subcostal abdominal wall defects.

Prognostic potential of circulating miR-93-5p in patients with colorectal cancer liver metastases. Neoplasma 2022; 69:430-442. [PMID: 35037761 DOI: 10.4149/neo_2021_210603n749] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Accepted: 09/07/2021] [Indexed: 11/08/2022]
Abstract
This study aimed to examine the expression pattern of tumoral and circulating miR-93-5p in patients with colorectal cancer (CRC) liver metastasis (CRLM) and to explore its predictive and prognostic potential. CRLM tissue, surrounding non-tumor liver tissue, and serum were obtained from 35 patients with CRLM. The expression pattern of tissue and circulating miR-93-5p in patients with CRLM was determined using quantitative polymerase chain reaction, using miR-16-5p for normalization. Sample-based cut-off values for CRLM and serum miR-93-5p expression were calculated using Receiver Operating Characteristic curve analysis to stratify the patients into high and low miR-93-5p expression groups which were that compared with patients' clinicopathological data, therapy response, one-year disease-free survival, and disease recurrence. Relative miR-93-5p expression was higher in CRLM in comparison to the non-metastatic liver tissue (p < 0.001). CRLM miR-93-5p expression showed moderate negative correlation with carcinoembryonic antigen levels (r = -0.406; p = 0.016). There were no differences in high-/low-miR-93-5p expression and therapy responders vs. non-responders, which was confirmed in vitro using metastatic and normal colonic cells SW620 and HCEC-1CT, respectively. No difference was observed in one-year recurrence-free survival in patients with high vs. low miR-93-5p expression in CRLM or serum. However, high miR-93-5p serum levels were significantly associated with early disease recurrence (p = 0.035). In conclusion, miR-93-5p serum levels could be potentially used as a prognostic factor for early disease recurrence in CRLM patients.

Total Fluoroscopy Time Reduction During Ultrasound- and Fluoroscopy-Guided Percutaneous Transhepatic Biliary Drainage Procedure: Importance of Adjusting the Puncture Angle. Med Sci Monit 2021; 27:e933889. [PMID: 34802031 PMCID: PMC8614062 DOI: 10.12659/msm.933889] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Accepted: 09/30/2021] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND The purpose of this observational cohort study was to assess patient and operator-dependent factors which could have an impact on total fluoroscopy time during ultrasound and fluoroscopy-guided percutaneous transhepatic biliary drainage (PTBD). MATERIAL AND METHODS Between October 2016 and November 2020, 127 patients with malignant biliary obstruction underwent ultrasound- and fluoroscopy-guided PTBD with the right-sided intercostal approach. The initial bile duct puncture was ultrasound-guided in all patients, and the puncture angle was measured by ultrasound. Any subsequent steps of the procedure were performed under continuous fluoroscopy (15 fps). The patients were divided in 2 groups based on the puncture angle: ≤30° (group I) and >30° (group II). In a retrospective analysis, both groups were compared for inter- and intragroup variability, technical success, total fluoroscopy time, and complications. RESULTS In group II, the recorded total fluoroscopy time (232.20±140.94 s) was significantly longer than that in group I (83.44±52.61 s) (P<0.001). In both groups, total fluoroscopy time was significantly longer in cases with a lesser degree of bile duct dilatation, intrahepatic bile duct tortuosity, presence of liver metastases, and multiple intrahepatic bile duct strictures. CONCLUSIONS The initial bile duct puncture angle was identified as an operator-dependent factor with the possible impact on total fluoroscopy time. The puncture angle of less than 30° was positively correlated with overall procedure efficacy and total fluoroscopy time reduction.

Abstract
Background The number of elderly patients with HCC who undergo liver resection is increasing. Because of the advanced age of the patients, increased postoperative morbidity and reduced overall survival are expected in this population. The study aim was to compare clinicopathologic and operative features, short- and long-term outcomes among hepatocellular carcinoma (HCC) patients from three age groups undergoing potentially curative liver resection in a developing country. Methods Prospectively collected data relating to 229 patients who underwent curative-intent liver resection from January 2009 until December 2018 were analyzed. The patients were divided into two age groups: G1 was below 70 years old (n=151) and G2 was 70 years old and older (n=78). Demographic, clinical, operative data, short- and long-term outcomes were compared between the two groups. Univariate and multivariate analyses of prognostic factors were performed. Results The mean overall morbidity rate of the patients was 31.1% (G1), and 46.2% (G2) by age group. Postoperative morbidity was significantly higher in the G2 group (p=0.03). There was no difference in major morbidity between the two groups (p=0.214). No significant difference in mortality rate and overall survival was found between the study groups (p=0.280, p=0.383). Both age ≥70 years (ie, G2 group) and liver cirrhosis were identified as prognostic factors for postoperative morbidity, and a Child-Pugh score B as a negative prognostic factor for overall survival. In subgroup analysis of patients with cirrhosis, age ≥70, diabetes mellitus and perioperative transfusion were identified as prognostic factors for postoperative morbidity. Conclusion The study confirmed the safety and feasibility of liver resection in elderly patients with HCC. However, appropriate patient selection among the elderly is mandatory in order to improve short- and long-term outcomes.

Liver resection versus transarterial chemoembolization for huge hepatocellular carcinoma: a propensity score matched analysis. Sci Rep 2021; 11:4493. [PMID: 33627697 PMCID: PMC7904801 DOI: 10.1038/s41598-021-83868-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Accepted: 02/09/2021] [Indexed: 12/13/2022] Open
Abstract
To date, it is unclear which treatment modality, liver resection (LR) or transarterial chemoembolization (TACE) is the more appropriate for patients with huge (≥ 10 cm) hepatocellular carcinoma (HCC). The study aim was to compare, using propensity score matching, short- and long-term outcomes of patients with huge HCC who underwent potentially curative LR or TACE. Patients with huge HCC who had been managed at the Clinical Center by curative-intent LR or by palliative TACE between November 2001 and December 2018 were retrospectively identified. The morbidity and mortality rates and overall survival were compared between the groups before and after the propensity score matching. Independent predictors of long-term survival were determined by multivariate analysis. A total of 103 patients with huge HCC were included; 68 were assigned to the LR group and 35 to the TACE group. The overall morbidity rate was higher in the LR group than in the TACE group before matching (64.7% vs. 37.1%, p = 0.012), while there was no difference after matching (60% vs. 30%, p = 0.055). The major morbidity and 30-days mortality were similar between the groups before and after matching. The LR group was associated with longer overall survival than the TACE group before matching (p = 0.032) and after matching (p = 0.023). Total bilirubin and TACE treatment were independent prognostic factors associated with long-term survival. In patients with huge HCC, liver resection provides better long-term survival than TACE and should be considered as the initial treatment whenever possible.

Abstract
Purpose There are limited data on expression of epithelial–mesenchymal transition (EMT) markers in patients with colorectal liver metastases (CRLM). The study aim was to evaluate the expression and prognostic significance of E-cadherin (CDH1), fibronectin (FN1) and vimentin (VIM) in patients with CRLM after curative-intent liver resection. Patients and Methods Thirty patients with CRLM managed by curative-intent liver resection were included in this prospective pilot study. Blood samples, colorectal liver metastases and surrounding non-tumor liver tissue were collected. Expression of CDH1, FN1 and VIM was analyzed by quantitative real-time polymerase chain reaction. Expression in CRLM and non-tumor liver tissue was compared, while expression in serum was correlated with CRLM expression. One-year recurrence-free survival was compared between patients with low and high CDH1, FN1 and VIM expression. Results The expression of CDH1 was similar in CRLM and non-tumor liver tissues, while FN1 and VIM expression was significantly lower in metastatic tissue (P=0.003 and pP<0.001, respectively). Serum expression of CDH1 and VIM was detected in 66.7% and 93.3% of patients, respectively, while FN1 was not detected in any of the patients. The correlation of CDH1 and VIM expression between CRLM and serum was not statistically significant. Decreased CDH1 expression in CRLM and decreased VIM expression in serum were associated with early recurrence after surgical treatment of CRLM. Conclusion Lower expression of CDH1 in CRLM and lower serum expression of VIM were found to be associated with early recurrence after liver resection for CRLM.

Abstract
We present a case report that demonstrates diagnostic and intraoperative challenges in the laparoscopic management of initially unrecognized splenic hydatid disease. A male patient, aged 44, was admitted to our department with a big unilocular splenic cyst, radiologically (ultrasonography, computed tomography) characterized as a simple cyst. Serological tests for anti-Echonococcus antibody were negative, and chests X-ray findings were unremarkable, so laparoscopic cyst fenestration with omentoplasty was planned. The intraoperative finding did not correspond to a simple splenic cyst. Hydatid daughter cysts were recognized after the careful opening of the cyst wall. The operation was completed without shifting to open procedures. Laparoscopic partial pericystectomy with omentoplasty is a safe and effective surgical procedure for the management of splenic hydatid disease.

Abstract
Purpose The aim of the study was to evaluate a prognostic value of preoperative neutrophil-to-lymphocyte ratio (NLR) on long-term survival of cirrhotic and noncirrhotic hepatocellular cancer (HCC) patients managed by a curative-intent liver surgery in a developing country. Patients and methods During the study period between November 1, 2001, and December 31, 2012, 109 patients underwent potentially curative hepatectomy for HCC. Data were retrospectively reviewed from the prospectively collected database. The median follow-up was 25 months. NLR was estimated by dividing an absolute neutrophil count by an absolute lymphocyte count from the differential blood count. Receiver operating characteristic curve was constructed to assess the ability of NLR to predict long-term outcomes and to determine an optimal cutoff value for all patients group, the subgroup with cirrhosis, and the subgroup without cirrhosis. The optimal cutoff values were 1.28, 1.28, and 2.09, respectively. Results The overall 3- and 5-year survival rates were 49% and 45%, respectively, for low NLR group and 38% and 26%, respectively, for high NLR group. The difference was statistically significant (p=0.015). Overall survival was similar between low and high NLR groups in patients with cirrhosis; no difference was found between the groups (p=0.124). In patients without cirrhosis, low NLR group had longer overall survival compared with high NLR group (p=0.015). Univariate analysis identified four factors as significant predictors of long-term survival: cirrhosis, Child-Pugh score, platelet count, and NLR. On multivariate analysis, only platelet count and NLR were independent prognostic factors of long-term survival. Conclusion Prognostic value of NLR was confirmed in noncirrhotic HCC patients who underwent curative-intent liver surgery. In HCC patients with cirrhosis, the prognostic role of NLR was not confirmed.

Abstract
Background Intrahepatic mass-forming cholangiocellular carcinoma (IMC) is the second most common primary liver tumor. The differentiation between IMC and solitary hypovascular liver metastases (SHLM) represents a diagnostic challenge due to many overlapping magnetic resonance imaging (MRI) features. Purpose To determine the value of diffusion-weighted imaging (DWI) in addition to conventional MRI for the distinction between intrahepatic mass-forming cholangiocarcinoma and solitary hypovascular liver metastases. Material and Methods Fifty-three patients with pathologically proven IMC (n = 31) and SHLM (n = 22) who had undergone MRI and DWI before surgery or percutaneous biopsy were enrolled in this study. The following MRI features were analyzed: the size and shape of the lesion, presence of capsular retraction and segmental biliary dilatation, T2-weighted (T2W) signal intensity, the presence of target sign on DWI and enhancement pattern. Apparent diffusion coefficient (ADC) values were calculated for each lesion ( b = 800 s/mm2). Univariate and multivariate logistic regression analyses were used to identify significant differentiating features between IMCs and SHLMs. Results Univariate analysis revealed that following parameters favor diagnosis of IMCs over SHLMs: lobulating shape, heterogeneous T2W signal intensity, capsular retraction, segmental biliary dilatation, target sign on DWI and rim-like enhancement on arterial phase followed by progressive enhancement in delayed phases. ADC values measured in the periphery of the lesion were significantly lower in IMCs in comparison to SHLMs. Multivariate analysis revealed that target sign on DWI was the most significant predictor of IMCs. Conclusion Qualitative DWI analysis with target sign significantly improves diagnostic accuracy for differentiation among IMC and SHLM lesions.

Abstract
Hepatocellular carcinoma (HCC) is characterized by a growing number of new cases diagnosed each year that is nearly equal to the number of deaths from this cancer. In a majority of the cases, HCC is associated with the underlying chronic liver disease, and it is diagnosed in advanced stage of disease when curative treatment options are not applicable. Sorafenib is a treatment of choice for patients with performance status 1 or 2 and/or macrovascular invasion or extrahepatic spread, and regorafenib is the only systemic treatment found to provide survival benefit in HCC patients progressing on sorafenib treatment. Other drugs tested in different trials failed to demonstrate any benefit. Disappointing results of numerous trials testing the efficacy of various drugs indicate that HCC has low sensitivity to chemotherapy that is in great part caused by multidrug resistance. Immunotherapy for HCC is a new challenging treatment option and involves immune checkpoint inhibitors/antibody-based therapy and peptide-based vaccines. Another challenging approach is microRNA-based therapy that involves two strategies. The first aims to inhibit oncogenic miRNAs by using miRNA antagonists and the second strategy is miRNA replacement, which involves the reintroduction of a tumor-suppressor miRNA mimetic to restore a loss of function.

Abstract
OBJECTIVE The aim was to demonstrate a diagnostic challenge of sclerosing mesenteritis initially considered as liposarcoma. CLINICAL PRESENTATION AND INTERVENTION A 45-year-old man was admitted with a painful abdominal mass. Abdominal computed tomography demonstrated a well- demarcated tumor in his left hemiabdomen, with a large fat component and areas of soft tissue attenuation suggestive of liposarcoma. Intraoperative findings showed a tumor arising from the greater omentum. The tumor was completely removed, and histopathology confirmed a pseudotumorous type of sclerosing mesenteritis with dominant mesenteric lipodystrophy. CONCLUSION This case showed that a pseudotumorous type of sclerosing mesenteritis should be considered in the differential diagnosis of the mesenteric tumors.

Abstract
Hepatocellular carcinoma (HCC) is one of the major malignant diseases in many healthcare systems. The growing number of new cases diagnosed each year is nearly equal to the number of deaths from this cancer. Worldwide, HCC is a leading cause of cancer-related deaths, as it is the fifth most common cancer and the third most important cause of cancer related death in men. Among various risk factors the two are prevailing: viral hepatitis, namely chronic hepatitis C virus is a well-established risk factor contributing to the rising incidence of HCC. The epidemic of obesity and the metabolic syndrome, not only in the United States but also in Asia, tend to become the leading cause of the long-term rise in the HCC incidence. Today, the diagnosis of HCC is established within the national surveillance programs in developed countries while the diagnosis of symptomatic, advanced stage disease still remains the characteristic of underdeveloped countries. Although many different staging systems have been developed and evaluated the Barcelona-Clinic Liver Cancer staging system has emerged as the most useful to guide HCC treatment. Treatment allocation should be decided by a multidisciplinary board involving hepatologists, pathologists, radiologists, liver surgeons and oncologists guided by personalized -based medicine. This approach is important not only to balance between different oncologic treatments strategies but also due to the complexity of the disease (chronic liver disease and the cancer) and due to the large number of potentially efficient therapies. Careful patient selection and a tailored treatment modality for every patient, either potentially curative (surgical treatment and tumor ablation) or palliative (transarterial therapy, radioembolization and medical treatment, i.e., sorafenib) is mandatory to achieve the best treatment outcome.

Abstract
BACKGROUND The treatment of cancer patients with mistletoe extract is said to prolong their survival and, above all, improve their quality of life. We studied whether the quality of life of patients with advanced pancreatic cancer could be improved by mistletoe extract. METHOD An open, single-center, group-sequential, randomized phase III trial (ISRCTN70760582) was conducted. From January 2009 to December 2010, 220 patients with locally advanced or metastatic pancreatic cancer who were receiving no further treatment for pancreatic cancer other than best supportive care were included in this trial. They were stratified by prognosis and randomly allocated either to a group that received mistletoe treatment or to one that did not. Mistletoe extract was given in escalating doses by subcutaneous injection three times a week. The planned interim evaluation of data from 220 patients indicated that mistletoe treatment was associated with longer overall survival, and the trial was terminated prematurely. After termination of the study, the results with respect to quality of life (assessed with the QLO-C30 scales of the European Organisation for Research and Treatment of Cancer) and trends in body weight were evaluated. RESULTS Data on quality of life and body weight were obtained from 96 patients treated with mistletoe and 72 control patients. Those treated with mistletoe did better on all 6 functional scales and on 7 of 9 symptom scales, including pain (95% confidence interval [CI] -29 to -17), fatigue (95% CI -36.1 to -25.0), appetite loss (95% CI -51 to -36.7), and insomnia (95% CI -45.8 to -28.6). This is reflected by the trend in body weight during the trial. CONCLUSION In patients with locally advanced or metastatic pancreatic carcinoma, mistletoe treatment significantly improves the quality of life in comparison to best supportive care alone. Mistletoe is an effective second-line treatment for this disease.

Abstract
A recurrent incisional hernia resulting from the rupture of low-weight polypropylene mesh is rarely reported in the literature. Three patients with recurrent incisional hernia due to low-weight polypropylene mesh central rupture were operated 5, 7 and 13 months after initial sublay hernioplasty. The posterior myofascial layer was fully reconstructed in all patients during the hernioplasty, whereas the anterior myofascial layer was only partially reconstructed. The recurrent hernia was managed using heavy-weight polypropylene mesh; in two patients, a new sublay hernioplasty was performed and in one patient an "open preperitoneal flat mesh technique" was performed under local anaesthesia as a day case procedure. If closing of the anterior myofascial layer cannot be ensured during the incisional hernioplasty, the use of low-weight polypropylene meshes should be avoided; preference should be given to the heavy-weight polypropylene meshes.

Viscum album [L.] extract therapy in patients with locally advanced or metastatic pancreatic cancer: a randomised clinical trial on overall survival. Eur J Cancer 2013; 49:3788-97. [PMID: 23890767 DOI: 10.1016/j.ejca.2013.06.043] [Citation(s) in RCA: 108] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2013] [Revised: 06/20/2013] [Accepted: 06/28/2013] [Indexed: 12/15/2022]
Abstract
BACKGROUND The unfavourable side-effects of late-stage pancreatic cancer treatments call for non-toxic and effective therapeutic approaches. We compared the overall survival (OS) of patients receiving an extract of Viscum album [L.] (VaL) or no antineoplastic therapy. METHODS This is a prospective, parallel, open label, monocentre, group-sequential, randomised phase III study. Patients with locally advanced or metastatic cancer of the pancreas were stratified according to a binary prognosis index, composed of tumour stage, age and performance status; and were evenly randomised to subcutaneous injections of VaL extracts or no antineoplastic therapy (control). VaL was applied in a dose-escalating manner from 0.01 mg up to 10mg three times per week. Patients in both groups received best supportive care. The primary end-point was 12-month OS, assessed in a group-sequential analysis. FINDINGS We present the first interim analysis, including data from 220 patients. Baseline characteristics were well balanced between the study arms. Median OS was 4.8 for VaL and 2.7 months for control patients (prognosis-adjusted hazard ratio, HR=0.49; p<0.0001). Within the 'good' prognosis subgroup, median OS was 6.6 versus 3.2 months (HR=0.43; p<0.0001), within the 'poor' prognosis subgroup, it was 3.4 versus 2.0 months respectively (HR=0.55; p=0.0031). No VaL-related adverse events were observed. CONCLUSION VaL therapy showed a significant and clinically relevant prolongation of OS. The study findings suggest VaL to be a non-toxic and effective second-line therapy that offers a prolongation of OS as well as less disease-related symptoms for patients with locally advanced or metastatic pancreatic cancer.

Abstract
BACKGROUND/AIM The aim of this study was to evaluate the clinical reliability of the immunoscintigraphy with radiolabeled monoclonal antibodies for the detection of metastases and recurrences of rectal carcinomas. METHODOLOGY A total of 65 patients underwent immunoscintigraphy with radiolabeled monoclonal antibodies. Indication for that examination was suspicious rectal cancer or suspicious rectal cancer recurrence and/or metastases. RESULTS The method proved to have 92.7% sensitivity, specificity 83.3%, positive predictive value 90.5%, negative predictive value 87.0% and accuracy 89.2%. There was a statistically significant relationship between immunoscintigraphy findings and rectoscopy findings (rs=0.415, p=0.013), as well as significant relationship between immunoscintigraphy findings and US findings (rs=0.332, p=0.001). Tumor marker levels were in positive correlation with findings of immunoscintigraphy (rs=0.845, p=0.001), especially raised CEA level (rs=0.816, p=0.004). Patients with higher CA19-9 level had higher Duke's stage (p=0.025). CONCLUSIONS We can conclude that immunoscintigraphy can be helpful in the detection of metastases and recurrences of colon carcinomas.

Abstract
BACKGROUND/AIMS The aim is to compare the radionuclide (DC) and ultrasonographic (US) method in the assessment of gallbladder (GB) motility. METHODOLOGY The study was performed in 15 controls (C), 10 patients with acute cholecystitis (AC), 20 patients with chronic acalculous cholecystitis (CAC), 26 patients with chronic cholecystitis with calculosis (CCC) as well as in 15 patients with GB dyskinesia (D). GB emptying period (EP), ejection fraction (EF) and ejection rate (ER) were estimated with dynamic cholescintigraphy (DC) and US. RESULTS The DC and US finding in the patients with AC was typical in all the patients, i.e. GB was not visualized at all on DC, while on US, stone was visible in the cystic duct. There were significant differences (p<0.05) between the EF and ER values obtained between C and the three groups of patients CAC, CCC and D, using both methods. However, there were no significant differences in EF, EP and ER values among CAC, CCC and D (p>0.05). There was also high correlation between the results obtained with both methods in all the groups of patients studied. CONCLUSIONS The results obtained by both methods are valuable for the assessment of GB motility. Although there are no significant differences and there is a high correlation between the values, radionuclide method is more precise, because it can register motility continuously.

Abstract
BACKGROUND/AIMS The aim of this investigation was to evaluate the role of detection of late mesh infection following incisional hernia repair with radiolabeled antigranulocyte antibodies. METHODOLOGY Mesh infection diagnoses were set up with clinical examination and laboratory analysis and confirmed by ultrasonography (US), computerized tomography (CT), scintigraphy with 99mTc-antigranulocyte antibodies and microbiological examination. RESULTS Of the 17 patients investigated, 6 had a late mesh infection, and 11 had both mesh infection and recurrent incisional hernia. Clear clinical signs of late mesh infection were present in 13 patients. Four remaining patients had non-specific discomfort and recurrent incisional hernia without clinical manifestation of mesh infection ('silent infection'). US was positive in 12/17 patients, CT in 13/17 patients, while scintigraphy with antigranulocyte antibodies in 17/17 patients. Therefore, sensitivity of US was 71%, of CT 76% and of scintigraphy 100%. In four patients late mesh infection was confirmed exclusively by 99mTc-antigranulocyte antibody scintigraphy, while US and CT did not indicate the infection. CONCLUSIONS According to the present results, scintigraphy with 99mTc antigranulocyte antibodies is a useful method for the detection of 'silent' abdominal wall infections after surgery, which is very important for prompt and appropriate therapy.

Abstract
AIM: To assess the clinical role of monoclonal immunoscintigraphy for the detection of metastasis and recurrence of colorectal cancer.
METHODS: Monoclonal immunoscintigraphy was performed in patients operated on for colorectal adenocarcinoma suspected of local recurrence and metastatic disease. The results were compared with conventional diagnostics.
RESULTS: Immunoscintigraphic investigation was done in 53 patients. Tumor recurrence occurred in 38 patients, and was confirmed by other diagnostic modalities in 35. In 15 patients, immunoscintigraphic findings were negative, and confirmed in 14 with other diagnostic methods. Comparative analysis confirmed good correlation of immunoscintigraphic findings and the results of conventional diagnostics and the level of tumor marker carcinoembryonic antigen. Statistical analysis of parameters of radiopharmaceutical groups imacis, indimacis and oncoscint presented homogenous characteristics all of three radiopharmaceuticals. The analysis of immunoscintigraphic target focus was clearly improved using tomography.
CONCLUSION: Immunoscintigraphy is highly specific and has a good predictive value in local recurrence of colorectal cancer.

Abstract
BACKGROUND/AIMS The aim of the study was the evaluation of the clinical validity of immunoscintigraphy with 99mTc labeled antibodies for the detection of metastases and recurrences of colorectal carcinomas. METHODOLOGY We examined 17 patients with colorectal carcinomas. Scintigraphy was performed with anti-CEA MoAb 99mTc-BW 431/26. RESULTS Recurrences of carcinomas were detected and confirmed by surgery in 6 patients, recurrences with liver metastasis in 5 patients, and only liver metastases in 3 patients. Planar immunoscintigraphy was positive in 5/8 patients with liver metastases and 8/11 patients with recurrences, whereas in 1/8 liver metastases and 3/11 recurrences were detected only by tomography. In two patients with metastases in the abdominal lymph nodes immunoscintigraphic findings both on planar scintigraphy and tomoscintigraphy were false negative. CONCLUSIONS Immunoscintigraphy with 99mTc labeled antibodies can be useful in the diagnosis of recurrences and metastases of colorectal carcinoma, viability assessment after radiotherapy and in the choice of the adequate surgical treatment.

Abstract
We report a case of heparin-induced thrombocytopenia thrombosis (HITT) syndrome in a patient prophylactically treated with low molecular weight heparin. A 66-year-old men underwent radiofrequency-assisted partial liver resection for colorectal carcinoma liver metastases a year-and-a-half after he had been operated for rectal cancer. In the postoperative period, patient was prophilactically treated with reviparin sodium. On the 8th postoperative day, the platelet count decreased by more than 50% without clinical signs of thrombosis. HITT syndrome was suspected on the 19th postoperative day, after iliacofemoropopliteal thrombosis had developed, and related diagnosis was supported by the strongly positive particle gel agglutination technique immunoassay. Heparin was withdrawn and alternative anticoagulant, danaparoid sodium, was introduced in therapeutic doses. Despite delayed recognition, favorable clinical outcome was achieved. HITT syndrome should be considered with priority among the possible causes of thrombocytopenia in a surgical patient on heparin.

Abstract
INTRODUCTION The results of numerous studies carried out over the last two decades have increasingly important cause of intrahospital infections (IHI). The aim of the study was to determine potential differences in distribution of individual risk factors between the group of patients in whom multiresistant Acinetobacter spp. was isolated and the group of patients in whom it was not. MATERIAL AND METHODS A prospective cohort study of 64 patients hospitalized with recorded IHI at the University Hospital for Digestive Surgery, Clinical Center of Serbia in the period between January and July 2011. The subjects were divided into two groups: patients with IHI in whom multiresistant Acinetobacter spp. was isolated from the biological material samples, and those with IHI without the presence of Acinetobacter spp. RESULTS Univariate data analysis indicated presence of statistically significant difference in distribution of certain types of surgeries (esophageal, pancreatic and hepatobiliary) among the two groups of subjects, distribution of CVC placement, application of mechanical ventilation and nasogastric tube placement, length of stay in ICU, lethal outcomes and administration of third generation cephalosporins. The results of multivariate analysis indicated that length of hospitalization in ICU (> 7 days), CVC, mechanical ventilation, esophageal, pancreatic and hepatobiliary surgeries as well as administration of third generation cephalosporins are independent risk factors for colonization and infection of patients with Acinetobacter spp. CONCLUSION Colonized or infected patients with Acinetobacter spp. play a major role in contamination of hands of the medical staff in the course of care and treatment, while inadequate hand hygiene of the staff leads to cross transmission of the causative organism to infection-free patients. Selective antibiotic pressure, particularly administration of quinolones and broad-spectrum cephalosporins, favor onset of multiresistant species of Acinetobacter spp., and therefore appropriate prophylaxis and treatment represent basic preventive measures against the onset and spreading of the causative organisms.

Abstract
The phenomenon now known as haemobilia was first recorded in XVII century by well known anatomist from Cambridge, Francis Glisson and his description was published in Anatomia Hepatis in 1654. Until today etiology, clinical presentation and management are clearly defined. Haemobilia is a rare clinical condition that has to be considered in differential diagnosis of upper gastrointestinal bleeding. In Western countries, the leading cause of haemobilia is hepatic trauma with bleeding from an intrahepatic branch of the hepatic artery into a biliary duct (mostly iatrogenic in origin, e.g. needle biopsy of the liver or percutaneous cholangiography). Less common causes include hepatic neoplasm; rupture of a hepatic artery aneurysm, hepatic abscess, choledocholithiasis and in the Orient, additional causes include ductal parasitism by Ascaris lumbricoides and Oriental cholangiohepatitis. Clinical presentation of heamobilia includes one symptom and two signs (Quinke triad): a. upper abdominal pain, b. upper gastrointestinal bleeding and c. jaundice. The complications of haemobilia are uncommon and include pancreatitis, cholecystitis and cholangitis. Investigation of haemobilia depends on clinical presentation. For patients with upper gastrointestinal bleeding oesophagogastroduodenoscopy is the first investigation choice. The presence of blood clot at the papilla of Vater clearly indicates the bleeding from biliary tree. Other investigations include CT and angiography. The management of haemobilia is directed at stopping bleeding and relieving biliary obstruction. Today, transarterial embolization is the golden standard in the management of heamobilia and if it fails further management is surgical.

Abstract
AIM To review and discuss the current strategies and controversies in the surgical management of colorectal cancer liver metastases. METHODS An analysis of indications, contraindications and scoring systems and concepts for expanding the indications for resection are discussed. The findings and discussion are related to our own experience, especially with radiofrequency assisted liver resection for colorectal cancer liver metastases. RESULTS Resection is the only management strategy that can potentially cure the patient. Certain controversies still exist, such as contraindications for surgery, timing of treatment of synchronous metastases, significance of extra-hepatic disease etc. Strategies that can improve respectability are discussed. Parenchyma oriented, tissue sparing surgery facilitates reresection should it become necessary. CONCLUSION The management of colorectal cancer liver metastases is still a confusing issue for general oncologists and general surgeons. A multidisciplinary approach that tailors the management strategy to the individual patient is the only option that provides optimal results for patients with advanced disease.

Abstract
BACKGROUND/AIMS Intraoperative blood loss is still a major concern for surgeons operating on the liver since it is associated with a significantly higher rate of postoperative complications and shorter long-term survival. An original radiofrequency (RF)-assisted minimal blood loss technique for transecting liver parenchyma is presented. METHODS In a prospective study, starting November 2001 and ending December 2005, a total of 90 RF-assisted liver resections were done. Pre-cut coagulative desiccation was produced by the Cool-tip (Valleylab, Tyco) water-cooled, single, RF tumor ablation electrode connected to a 480-kHz 200 W generator (Valleylab Cool-tip RF System). Vascular occlusion techniques and low central venous pressure anesthesia were not used. RESULTS Only 14 (15.5%) patients received blood transfusion (mean transfused blood volume 397 ml; mode 310 ml) and 10 of 14 patients received <310 ml of blood. There was no statistical difference between the patients who underwent major and minor liver resection in frequency of blood transfusion. Blood loss was associated with dense adhesions and difficult liver mobilization and not with liver transection. CONCLUSION The 'sequential coagulate-cut' RF-assisted liver resection technique is a safe liver transection technique associated with minimal blood loss and it has facilitated tissue-sparing liver resection.

Abstract
Introduction. The dilemma whether to use the mesh or non mesh technique in the management of umbilical, epigastric and small incisional hernia is slowly fading away. The open preperitoneal "flat mesh" technique performed as ambulatory surgery may be one of the solutions. The Aim. The aim of this retrospective study is to present the results of open preperitoneal "flat mesh" technique in the management of umbilical, epigastric and small incisional hernia within Material and methods. This study included 34 patients (11 of them with umbilical, 13 with epigastric and 8 of them with small incisional hernia) operated by one surgeon in the period January 2004 - January 2006. Results. The median operative time was 52 minutes for umbilical hernia?s, 43 minutes for epgastric and 54 minutes for incisional hernia?s. The ambulatory surgery was performed at 91% of patients. The median hospitalization was 4h for patients with umbilical hernia?s, 3,7h for patients with epigastric and, 7,7h for patients with small incisional hernia. The follow up is 10,5 months. Apart of one superficial infection other complications were absent. Conclusion. The open preperitoneal "flat mesh" technique performed in local anesthesia as an ambulatory surgery provides good results in the management of umbilical, epigastric and small incisional hernia.

Abstract
Traditionally, the operation of hernia is considered as a clean operation due to expected, low incidence of infection, on the spot of surgical work (SSI). The incidence of SSI in hernia surgery is more frequent then it is assumed. The important risk factors for SSI are the following: type of hernia (inguinal, incisional), operative approach (open - laparoscopic), usage of the prosthetic material and drainage. Comparing to inguinal hernia repair, incisional hernia repair, is more frequently followed by the infection. The laparoscopic operations are followed with the lower incidence of SSI then in the case of open operation. The usage of the mesh does not increase the incidence of SSI, although the consequences of the mesh infection may be severe. A type I of the prosthesis is more resistant to the infection then prosthesis II and III. The mesh infection (type I) never involves its body but it is present around sutures and bended edges. The mesh infection Type II involves entire prosthesis while in the case of Type III it is present in its peripheral part. In the case of SSI, a prosthesis Type I is possible to be saved, while prosthesis Type II must be removed completely; and the same is for the Type III (the partial removal is rarely suggested). The defect that remained after excision of non-resorptive prosthesis is a long-term and very complicated surgical problem. In regard to the position of the mesh, SSI is more common if the mesh is placed subcutaneously then in the case of sub-aponeurotic peri-muscular, pre-aponeurotic retromuscular or pre-peritoneal mesh placemen. If the infection is present the non-tension techniques using non-resorptive prosthetic implants are not recommended. the presence of drainage and its duration increases the incidence of SSI. It is more common for incisional hernioplasty then for inguinal hernia repair. If there is an indication for drainage it should be as short as possible. The cause of SSI for elective operations are bacteria?s that arrives from the skin, while in the case of opening of various organs dominant bacteria?s originate from them. The superficial infection does not lead to the recurrence, while it is very possible in the case for deep infection. There are no prospective studies that justify the usage of antibiotic prophylaxes in hernia surgery. The antibiotic prophylaxis in hernia surgery. The antibiotic prophylaxis is indicated for the clean operations when placing the implants and when severe complication is expected. The appearance of SSI increases the price of treatment and may lead to the recurrence.

Abstract
In solving inguinal hernias, surgeons today have in front of them many variations of different operative procedures (both tensional and non-tensional techniques). They are performed through operative or endoscope approach. Classical tension techniques present the operation of choice for smaller indirect, direct or femoral hernias among younger patients while non/tensional techniques are the best solution for all types of inguinal hernia among older patients with big destruction of transversal fascia and the best solution for most of recurrent hernias. Positioning of mesh with non-tensional techniques can be completed on different levels, with big hernias where the biggest part of transversal fascia of miopectineal orifitium is destroyed it is anatomically the most useful to place the mesh in preperitoneal space. Rives technique is the base of that concept and it presents one of good solutions in that kind of situations. In the period January 2001 until december 2002 using different operative techniques the authors treated 99 inguinal hernias of which 78 were primary and 21 recurrent hernias. Rives technique was performed in 46 cases (46.5%) among which 26 cases were primary inguinoscrotal hernias (3 patients IIIA, 22 patients IIIB, 1 patient IIIC, according to Nyhus classification) and 20 cases were recurrent hernias (6 patients IVA, 11 IVB, 3 IVD). Complications after Rives technique were the following: 1 recurrence (2.17%), 1 ischemic orchitis (2.17%) and 1 scrotal hematoma (2.17%). Infections and chronic pain were not present. The follow up was from 30 days to 2 years. Authors have shown that Rives technique is reliable solution for primary indirect, direct and femoral hernias with big hernial defect (especially for big, so called "giant" inquinoscrotal hernias) and for all types of recurrent hernias. The advantage of the technique is an easy performance without some previous special training because of the fact that dissection and preparation is the same as for the tension techniques. With small amount of prosthetic material all weak points of miopectineal orifitium are closed. The real risks of this technique are ischemic orchitis and chronis neuralgia in treatment of recurrent hernias and the presence of polypropylene mesh in Bogras space.

Abstract
After the introduction of prosthetic material in hernia surgery the fundamental changes in operative strategy occurred. This is because the coverage of myopectineal orifitium with non-absorbable prosthesis decreases the incidence of recurrences. Because of the appearance of lateral re-recurrences after the classical Rives procedure, we modified the operative technique. The modified Rives technique consists of the following: always polypropilen mesh 15x10 cm; creation of the new internal inguinal ring between Poupart's ligament and mesh; no lateral notching the mesh and anchoring mesh 2-3 cm from the medial, inferior, lateral and superior edge. During the period January 2001-December 2003, 34 cases of recurrent hernias were operated on 7th dept. of I Surgical Clinic of CCS. The recurrences were managed by classical (10/34) or modified Rives technique through direct inguinal approach (22/34), less frequently Lichtenstein procedure (1/34) and McVay (1/34) technique. Among 10 patients with recurrent inguinal hernias managed by classical Rives technique 2 re-recurrences appeared (indirect and interstitial) and 2 cases of infection (immediately after the operation or 7 months after the operation), and in the group of 22 cases with recurrent inguinal hernias managed by modified Rives technique the aim complications didn't appear. Using the modified Rives technique we managed the primary hernias in 56 cases without recurrences and infections. The modified Rives technique, because of the way of mesh fixation (all around), no lateral notching of mesh and remaining hem in all directions secures abdominal wall protection 2-3 cm from the line of fixation and prevents any movement of the mesh. This procedure enables management of all inguinal hernias regardless to their size and full protection of the medial, femoral and lateral inguinal triangle. The modified Rives technique is the technique of choice for big multiple defects (giant inguino-scrotal and re-recurrences), especially among patients with increased intra-abdominal pressure when other techniques may be insufficient because of mesh protrusion.
