Increased use of percutaneous technique for totally implantable venous access devices. Is it real progress? A 27-year comprehensive review on early complications.

BackgroundFirst implantation of a totally implantable venous access device (TIVAD) was performed in 1982 with surgical technique. Since then, these devices have permitted infusion of total parenteral nutrition, antibiotics, blood products, and, above all, they have definitively changed the quality of life of patients with cancer. However, with the increase of percutaneous procedures, we have assisted with a concomitant raise of immediate postprocedural life-threatening complications. The aim of this study was to review the literature during a 27-year period, with regard to the changes of incidence of immediate complications after percutaneous or surgical cutdown for TIVAD’s implant.Materials and MethodsAn extensive search of relevant literature was carried out by using MEDLINE (PubMed) and Google Scholar. We gathered articles from 1982 to 2009 that quoted patient’s number, type of pathology, specialist involved, number of devices implanted, site and technique of implantation (surgical cutdown or percutaneous technique), and immediate complications occurrence.ResultsA total of 952 reports were screened, and finally only 45 articles addressing all inclusion criteria were used for the present study. A total of 11,430 TIVADs implanted in 11,381 patients were analyzed. Pneumothorax, hemothorax, arterial puncture, and hemoptysis developed only after percutaneous procedures. Atrial fibrillation, hematomas, and malpositioning were more frequent after percutaneous approach. The total amount of immediate complications in patients submitted to percutaneous implant was 4.5%, compared with 0.9% subsequent to cutdown technique.ConclusionsDespite the increased use of percutaneous technique for TIVADs’ implantation, surgical cutdown, because of its safety, remains the best approach to avoid possible fatal immediate complications.

TachoSil use in abdominal surgery: a review

The success of any surgical procedure is based on adequate hemostasis. Many different biomaterial products can be used to achieve that aim. The products that can be used during surgery may be classified as topical hemostats, sealants, and adhesives. Hemostats can clot blood. Sealants can create sealing barriers. Adhesives bond tissue together. Collagen, gelatin, and cellulose are hemostat agents. TachoSil® is a development of TachoComb® and TachoComb® H. TachoComb is made with equine collagen, bovine thrombin, bovine aprotinin, and human fibrinogen. The clinical efficacy of TachoSil was shown firstly by a clinical study of hepatic surgery. In the study, TachoSil proved to be superior to argon beamer in obtaining effective and fast intraoperative hemostasis. Following the study, many applications in different fields of surgery have been reported in the literature. The use of TachoSil in open abdominal surgery and its relevant results have encouraged the use of TachoSil in laparoscopic surgery. Unfortunately, its use in laparoscopy has not become as popular as it is in open surgery, due to a lack of efficacious techniques. Immunologic reactions to compounds of TachoSil and the transmission of infectious diseases are two major risks concerning topical hemostasis. Even though the risk of severe immunologic reactions to bovine material is low, TachoSil has gradually replaced all bovine material with material of human origin and has therefore eliminated the associated risks of bovine material. TachoSil has a good satisfaction rate among surgeons and reduces both the operating time for patients and the time spent in intensive care units.

Laparoscopic Reversal of Hartmann’s Procedure: State of the Art 20 Years after the First Reported Case

Introduction. Aim of the present work is to review the literature to point out the role of laparoscopic reversal of Hartmann procedure. Material and Methods. Number of patients, age, sex, etiology, Hinchey classification, interval between procedure and reversal, position of the first trocars, mean operative time (min), number and causes of conversion, length of stay, mortality, complications, and quality of life were considered. Results. 238 males (52.4%) and 216 females (47.6%) between 38 and 67 years were analyzed. The etiology was diverticulitis in 292 patients (72.1%), carcinoma in 43 patients (10.6%), and other in 70 patients (17.3%). Only 7 articles (22.6%) reported Hinchey classification. The interval between initial procedure and reversal was between 50 and 330 days. The initial trocar was open positioned in 182 patients (43.2%) through umbilical incision, in 177 patients (41.9%) in right upper quadrant, and in 63 patients (14.9%) in colostomy site. The operative time was between 69 and 285 minutes. A total of 83 patients (12.1%) were converted and the causes were reported in 67.4%. The length of stay was between 3 and 12 days. 5 patients (0.7%) died. The complications concern 112 cases (16.4%). Conclusion. The laparoscopic Hartmanns reversal is safer and achieves faster positive results.

Comparison of Two Entry Methods for Laparoscopic Port Entry: Technical Point of View

Laparoscopic entry is a blind procedure and it often represents a problem for all the related complications. In the last three decades, rapid advances in laparoscopic surgery have made it an invaluable part of general surgery, but there remains no clear consensus on an optimal method of entry into the peritoneal cavity. The aim of this paper is to focus on the evolution of two used methods of entry into the peritoneal cavity in laparoscopic surgery.

Persistent increase in alpha-fetoprotein level in a patient without underlying liver disease who underwent curative resection of hepatocellular carcinoma. A case report and review of the literature

IntroductionAlpha-fetoprotein (AFP) is an oncofetal protein produced by hepatocellular carcinoma (HCC). AFP level can also be elevated in other neoplastic or non-neoplastic conditions. An elevated AFP level has high diagnostic significance for HCC; at a level of >200 ng/mL, the probability of HCC is >90%. The aim of the present paper is to report a patient who underwent curative resection of HCC, who had a persistently elevated AFP level postoperatively but did not develop recurrence during a 2-year follow-up period. A review of the literature is also presented.Case reportAn 82-year-old male was referred following a computed tomography scan showing a 160 mm diameter mass in the left lobe of the liver. This huge mass was diagnosed as HCC, arising in the absence of cirrhosis or viral hepatitis. After tumor removal, the patient’s high AFP level persisted for 2 years.ConclusionAs steatosis was the only pathological change in the remnant liver, this may have caused the persistently elevated AFP level in this patient.

Totally Implanted Venous Access Devices Implanted in the Saphenous Vein. Relation Between the Reservoir Site and Comfort/Discomfort of the Patients

BACKGROUND When a totally implantable venous access device (TIVAD) is implanted in the femoral or saphenous vein, the port can be placed in the abdominal wall, thigh, or anteroinferior thoracic wall. This study analyzed the relationship between the position of the port and patient comfort. METHODS All patients who underwent TIVAD implantation from 1995 to 2011 were included in the study. Sex, age, indication for TIVAD implantation, contraindication for implantation in a vein draining into the superior vena cava, surgical technique, length of procedure, complications, difficulties recorded by nurses, and patient comfort or discomfort were recorded. RESULTS The TIVAD was implanted in the saphenous vein in 6 of 581 patients (1.3%) who received a TIVAD, consisting of four male subjects and two female subjects aged 35 to 56 years (mean age: 47.3 years), who all underwent TIVAD implantation for the treatment of a solid tumor. The port was positioned in the anteroinferior thoracic wall in one patient, the abdominal wall in one patient, the anterior thigh in three patients, and the lateral thigh in one patient. The mean procedure duration was 52 minutes (range: 20-135 minutes). No immediate or early complications were recorded. The nurses had difficulty in puncturing the port in the abdominal wall. Patient comfort levels were high when the port was placed in the anterior thigh. CONCLUSION The anterior thigh may be the most useful and comfortable position for the port of a TIVAD implanted in the inferior vena cava. Larger studies should be undertaken to confirm this.

Increased rate of cholecystectomies performed with doubtful or no indications after laparoscopy introduction: a single center experience

BackgroundDuring recent years laparoscopic cholecystectomy has dramatically increased, sometimes resulting in overtreatment. Aim of this work was to retrospectively analyze all laparoscopic cholecystectomies performed in a single center in order to find the percentage of patients whose surgical treatment may be explained with this general trend, and to speculate about the possible causes.Methods831 patients who underwent a laparoscopic cholecystectomy from 1999 to 2008 were retrospectively analyzed.ResultsAt discharge, 43.08% of patients were operated on because of at least one previous episode of biliary colic before the one at admission; 14.08% of patients presented with acute lithiasic cholecystitis; 14.68% were operated on because of an increase in bilirubin level; 1.56% were operated on because of a previous episode of jaundice with normal bilirubin at admission; 0.72% had gallbladder adenomas, 0.72% had cholangitis, 0.36% had biliodigestive fistula and one patient (0.12%) had acalculous cholecystitis. By excluding all these patients, 21.18% were operated on without indications.ConclusionsThe broadening of indications for laparoscopic cholecystectomy is undisputed and can be considered a consequence of new technologies that have been introduced, increased demand from patients, and the need for practice by inexperienced surgeons. If not prevented, this trend could continue indefinitely.

Seizure attack and Morgagni diaphragmatic hernia: incidental diagnosis or direct correlation?

Asymptomatic Morgagni hernia can be discovered in adults as an incidental finding or because of acute gastrointestinal symptoms. We report a case of a 76-year-old man with an incidental diagnosis of seizure attack. Obesity and the increased abdominal pressure caused by abdominal muscles contraction during seizure could have contributed to the clinical presentation. The omentum, small bowel, and transverse colon were found in the right side of the chest using an open transabdominal approach. The hernia sac was excised and the diaphragmatic defect closed by direct suturing. The postoperative period was uneventful and the shortness of breath attributed to obesity disappeared.

Abdominal perineal resection or wilde local excision in primary anorectal malignant melanoma. Case report and review

Introduction Primary anorectal malignant melanoma is a rare and aggressive tumor that carries a poor prognosis. Anorectal melanoma (ARM) is often misdiagnosed as hemorrhoids adenocarcinoma polips and rectal cancer. ARM spreads along sub-mucosal planes and is often to wide-spread for complete resection at time of diagnosis and almost all patients die because of metastases. Presentation of the case A 77-year-old male patient presented a history of recurrent rectal bleeding and whose histopathological diagnosis was melanoma. Discussion The treatment of choice remains controversial. Surgery with complete resection represents the typical treatment. However standard operative procedures related to the area of resection and lymph dissection have yet to be established. Abdominal perineal resection (APR) with or without bilateral inguinal lymphadenectomy or wide local excision (WLE) have been used to manage patients with ARM. Conclusion The higher serum levels of LDH and YKL-40 are suggestive for Anorectal Melanoma diagnosis. The decrease of these findings may be associated with good prognosis. The review of both APR and WLE options suggests no significant difference in survival among patients.

Splenic autotransplantation in a patient with human immunodeficiency virus infection: a case report.

IntroductionSplenectomy is performed mostly because of traumatic events that cause rupture of the spleen. Postsplenectomy, a patient has a higher risk of developing sepsis. Autotransplantation of splenic tissue decreases the risk of opportunistic infection and sepsis, but its role in patients with human immunodeficiency virus is debated because the spleen is a replication site, especially during the asymptomatic phase of this infection. We present a case of a patient with human immunodeficiency virus infection who was admitted to our hospital for a traumatic rupture of the spleen and underwent spleen autotransplantation.Case presentationA 36-year-old Caucasian man was admitted to the shock trauma center of our hospital after a car accident. Anamnesis showed that the patient had been human immunodeficiency virus-positive for 13 years. A computed tomography scan showed abundant fluid collection in his superior and inferior abdomen caused by splenic rupture, with no other associated intra-abdominal lesions. During surgery, the spleen appeared severely damaged. A splenectomy was performed, and 35 g of splenic tissue was autotransplanted in a pouch created in the omentum. No complications occurred after surgery, and our patient was discharged from our hospital nine days after the operation. One year later, computed tomography and scintigraphy showed that the transplanted tissue was functioning well.ConclusionsAutotransplantation of splenic tissue decreases the risk of opportunistic infection and sepsis, and it might also be useful in patients with human immunodeficiency virus. Other studies need to be done to validate this hypothesis.
