External Jugular Vein Cutdown Approach, as a Useful Alternative, Supports the Choice of the Cephalic Vein for Totally Implantable Access Device Placement

BackgroundCephalic vein (CV) cut down for totally implantable venous access device (TIVAD) placement has been accepted as an alternative to the percutaneous subclavian vein approach. The aim of this retrospective study was to validate the external jugular vein (EJV) cut-down approach when the CV is not feasible.MethodsPatients receiving a TIVAD from January 1995 to December 2003 were included in this study. Age, sex, surgical technique, disease, device used, length of the procedure, and morbidity were considered.ResultsA total of 427 TIVADs were placed in 425 patients: 253 men (59.5%) and 172 women (40.5%) aged 31 to 79 years. Of 425 patients, 5 were excluded; 420 underwent a CV cut down on the first attempt, and 391 (93.1%) procedures were successful. Among the final 29 patients, 20 (68.96%) underwent a TIVAD placement through the ipsilateral EJV cut-down approach. In the remaining nine patients (31.04%), TIVAD placement was performed through the ipsilateral internal jugular vein in four cases, via the ipsilateral axillary vein in three cases, and through the ipsilateral coracobrachial vein in the other cases. No immediate postoperative complications were detected in any of the patients.ConclusionsTIVAD placement by the CV cut-down approach is safe and fast, and its success rate is very high. By avoiding the immediate complications associated with the percutaneous approach, the EJV cut down has to be considered a valid, safe, and suitable alternative when the CV is not feasible.

Adjusting CA19-9 values to predict malignancy in obstructive jaundice: Influence of bilirubin and C-reactive protein

AIM To find a possible relationship between inflammation and CA19-9 tumor marker by analyzing data from patients with benign jaundice (BJ) and malignant jaundice (MJ). METHODS All patients admitted for obstructive jaundice, in the period 2005-2009, were prospectively enrolled in the study, obtaining a total of 102 patients. On admission, all patients underwent complete standard blood test examinations including C-reactive protein (CRP), bilirubin, CA19-9. Patients were considered eligible for the study when they presented obstructive jaundice confirmed by instrumental examinations and increased serum bilirubin levels (total bilirubin > 2.0 mg/dL). The standard cut-off level for CA19-9 was 32 U/mL, whereas for CRP this was 1.5 mg/L. The CA19-9 level was adjusted by dividing it by the value of serum bilirubin or by the CRP value. The patients were divided into 2 groups, MJ and BJ, and after the adjustment a comparison between the 2 groups of patients was performed. Sensitivity, specificity and positive predictive values were calculated before and after the adjustment. RESULTS Of the 102 patients, 51 were affected by BJ and 51 by MJ. Pathologic CA19-9 levels were found in 71.7% of the patients. In the group of 51 BJ patients there were 29 (56.9%) males and 22 (43.1%) females with a median age of 66 years (range 24-96 years), whereas in the MJ group there were 24 (47%) males and 27 (53%) females, with a mean age of 70 years (range 30-92 years). Pathologic CA19-9 serum level was found in 82.3% of MJ. CRP levels were pathologic in 66.6% of the patients with BJ and in 49% with MJ. Bilirubin and CA19-9 average levels were significantly higher in MJ compared with BJ (P = 0.000 and P = 0.02), while the CRP level was significantly higher in BJ (P = 0.000). Considering a CA19-9 cut-off level of 32 U/mL, 82.3% in the MJ group and 54.9% in the BJ group were positive for CA19-9 (P = 0.002). A CA19-9 cut-off of 100 U/mL increases the difference between the two groups: 35.3% in BJ and 68.6% in MJ (P = 0.0007). Adjusting the CA19-9 value by dividing it by serum bilirubin level meant that 21.5% in the BJ and 49% in the MJ group remained with a positive CA19-9 value (P = 0.003), while adjusting the CA19-9 value by dividing it by serum CRP value meant that 31.4% in the BJ group and 76.5% in the MJ group still had a positive CA19-9 value (P = 0.000004). Sensitivity, specificity, positive predictive values of CA19-9 > 32 U/mL were 82.3%, 45% and 59.1%; when the cut-off was CA19-9 > 100 U/mL they were, respectively, 68.6%, 64.7% and 66%. When the CA19-9 value was adjusted by dividing it by the bilirubin or CRP values, these became 49%, 78.4%, 69.4% and 76.5%, 68.6%, 70.9%, respectively. CONCLUSION The present study proposes CRP as a new and useful correction factor to improve the diagnostic value of the CA19-9 tumor marker in patients with cholestatic jaundice.

Liver damage after transarterial chemoembolization without embolizing agent in unresectable hepatocellular carcinoma.

Aim and Background Transarterial chemoembolization represents a therapy for hepatocellular carcinoma, but in cirrhotic patients affected by large or multifocal HCC with poor hepatic functional reserve, the procedure can damage normal parenchyma. We analyzed the effects on hepatic function of a modified chemoembolization consisting of ethiodized oil (Lipiodol Ultra Fluid) and epirubicin without gelatine sponge (C-LIP). Methods Of 90 patients with hepatocellular carcinoma observed from January 1995 to December 1999, 16 with a diagnosis of advanced (large or multifocal) disease underwent 19 C-LIP. The 30th post-C-LIP day was considered as a checkpoint of the biochemical parameters for a possible hepatic failure. The value of alpha-fetoprotein and the clinical finding of ascites were also considered after 30 days. Results Postoperative values of serum aspartate aminotrasferases, as well as alanine aminotransferase, were significantly higher than preoperative values (P = 0.002 and P = 0.019, respectively) (Table 1). In all patients, there was a significant increase in postoperative total serum bilirubin (P = 0.003). Statistical analysis showed a significant finding of postoperative ascites (P = 0.035) and the effectiveness of C-LIP on neoplastic tissue by a decrease of alpha-fetoprotein values at 30 days (P = 0.067). Conclusions Transcatether arterial chemoembolization could represent an effective therapy against multifocal or advanced hepatocellular carcinoma, and its effectiveness is probably not decreased by using a modified procedure without embolizing agent (C-LIP). However, even when performing such a safe procedure, the hepatic functional reserve of the individual patient needs to be accurately evaluated in order to avoid liver failure.

FEASIBILITY OF A PORTO-INTRACAVAL SHUNT FOR LIVER TOTAL VASCULAR EXCLUSION IN THE RABBIT: PRELIMINARY REPORT

The animals do not tolerate prolonged caval and/or portal clamping which induces negative pathophysiological events such as release of chinines, damage of the intestinal mucosa, and bacterial translocation. In human liver surgery, these problems have been solved by bio‐pump for veno‐venous bypass. In order to find a simple method to reproduce a veno‐venous bypass, we developed the porto‐intracaval shunt and used it in six adult rabbits. The shunt tested was a self constructed 7‐french polyurethane shunt modeled as an inverted Y. The inferior vena cava vein below the diaphragm and below the liver and the portal vein were gently dissected. The two longer branches of the shunt were inserted in the cava vein, while the remaining branch of the Y shunt was inserted in the portal vein. After clamping the hepatic artery, the liver was partially resected in three animals and after 60 min the shunt was removed. The insertion of the shunt was always easy and the animals tolerated well the procedure and the anhepatic phase. Our study has been performed in order to test especially the technical feasiblity of this shunt in an effort to reduce portal and caval stasis during the anhepatic phase of the surgical procedures that require caval and portal clamping. The technical feasibility has been obtained but we believe that the materials and dimensions of the shunt have to be perfected and adapted depending on the size of the cava and portal veins.

Laparoscopic implementation of the Altemeier procedure for recurrent rectal prolapse. Technical note

INTRODUCTION Many surgical options exist to treat rectal prolapse with different indications, feasibility and results in urgent and complicated cases. These include perineal or abdominal approaches including rectopexy with or without resection. Perineal approaches have reduced surgical invasivity and hospital stay if compared to transabdominal approaches by open surgery or laparoscopy. Up to now there was still a clear dividing line for surgical treatment between the perineal approach, used more for complicated emergency case while the transabdominal open, or laparoscopic approach more common in elective surgery, but more complex to perform. PRESENTATION OF CASE A 37 year old female patient affected by psychiatric disease presented with an unreducible second recurrence of a complicated rectal prolapse. The patient was treated with a third Altemeier procedure but now performed under laparoscopic control. The patient recovered promptly without any complication or recurrence up to the 24 months follow-up. DISCUSSION To the best of our knowledge, this is the first case report describing the combined laparoscopic-perineal approach for the treatment of a complicated recurrence of rectal prolapse. The technical feasibility, the rapidity, the optimal outcome and the rationale behind this option all suggest that this laparoscopic assistance certainly allows an implementation of the effectiveness, safety and results of an established effective perineal approach. CONCLUSION This combined approach has the advantage of maintaining the simplicity and rapidity of conventional perineal surgery, adding the advantages of abdominal control and avoiding the risks, the invasivity, and the longer duration of more complex laparoscopic procedures.

Microsurgery and varicocele : State of the art

Many surgical procedures have been proposed in the treatment of varicocele; however, the rate of recurrence and of postoperative complications, together with important correlation of this disease with male sterility, has played an important role in determining the success of microsurgery. In the present brief review, the indications for microsurgery and microsurgical dissection and/or anastomosis are described in comparison to traditional surgery.

Efficacy of the Laparoendoscopic "Rendezvous" to Treat Cholecystocholedocholithiasis in 210 Consecutive Patients: A Single Center Experience

Objective: The simultaneous laparoendoscopic “rendezvous” (LERV) represents an alternative to sequential or totally laparoscopic approaches for patients affected by cholecystocholedocholithiasis. The aim of this study was to analyze the results in a large series of 210 consecutive patients. Materials and Methods: From 2002 to 2016 all patients affected by cholecystocholedocholithiasis were treated with a standardized “tailored” LERV. The relevant technical features of the procedure were recorded. An analysis of feasibility, effectiveness in stone clearance, and safety was performed. Results: Among 214 patients with common bile duct stones, 210 were treated with LERV and 4 with open rendezvous approach. Intraoperative cholangiography confirmed common bile duct stones in 179 patients (85.2%) or sludge in 18 (8.5%) and in 98.9% stone clearance was obtained endoscopically. Endoscopic papilla cannulation was feasible in 161 patients (76.7%), whereas in 49 (23.3%) a transcystic guidewire was needed. The overall LERV feasibility was 96.6%. The conversion rate to open surgery was 3.3%. Minor morbidity was observed in 1.9% of cases, mortality in 0.47%, and the mean hospital stay was 4.3 days. Conclusions: These results confirm the high effectiveness of LERV. This approach to treat cholecystocholedocholithiasis should be preferred and therefore implemented where a strong collaboration between surgeons and endoscopists is possible.
