Liver Transplantation for Alagille's Syndrome

Twenty-three children with Alagille's syndrome and end-stage liver disease underwent liver transplantation with cyclosporine and low-dose steroid immunosuppression. Two to 9 years (mean, 4.4 years) after surgery, 13 (57%) of the children were still alive, with normal liver function. Three of the fatalities were due to cardiovascular failure secondary to associated cardiopulmonary disease. Mortality was higher among patients who had more severe cardiac disease and patients who had previously undergone a Kasai procedure. Although it has a higher than average risk, liver transplantation can be efficacious in patients with Alagille's syndrome and end-stage liver disease.

Acute pancreatitis after liver transplantation: incidence and contributing factors

In order to assess the incidence and possible predisposing and contributing factors in the development of acute pancreatitis after liver transplantation, we reviewed the medical records of all 1832 adult patients who underwent 2161 orthotopic liver transplantation (OLTx) procedures in our center between January 1987 and September 1992. Of these patients, 55 (3 % incidence) developed clinical pancreatitis and 247 (13.4 % incidence) developed hyperamylasemia (biochemical pancreatitis). Overall mortality in cases of clinical pancreatitis was 63.6 %. The mortality in cases of hyperamylasemia was similar to that found in the general liver transplant population (i. e., 23 %). A strong correlation was found between pancreatitis after liver transplantation and end-stage liver disease due to hepatitis B (30 % of the cases, P = 0.00001). Extensive surgical dissection around the pancreas (P < 0.05), the type of biliary reconstruction following liver transplantation (P < 0.05), and the number of liver grafts received by the same patient (P = 0.00001) appeared to be possible contributing factors as did the duration of venovenous bypass and the quantity of IV calcium chloride administered intraoperatively

Hepatic artery pseudoaneurysm ligation after orthotopic liver transplantation-a report of 7 cases

Pseudoaneurysm (PA) is a rare but life-threatening complication of liver transplantation. The authors present their experience on 7 patients treated by ligation of a post-OLT PA. Hepatic artery ligation or embolization was performed from 10 to 70 days after liver transplantation. Of the seven patients, four survived, one developed a biliary stricture, treated by percutaneous ballon dilatation, two died of a complication not related to treatment, and one died of multiple organ failure. © 1992 by Williams & Wilkins

Techniques and Current Role of Sentinel Lymph Node (SLN) Concept in Gastric Cancer Surgery

Gastric cancer patients represent a rather divergent patient group and in certain carefully selected cases of early forms of gastric cancer the D2 gastrectomy could be considered a more radical procedure than the biological and oncological characteristics of the primary tumor on the gastric wall would require. As any unnecessary dissection increases morbidity without always respective survival benefits, an approach that could accurately predict and actually dictate the exact extent of lymph node dissection would be ideal. It is more than logical the assumption that the standard D2 lymphadenectomy could represent an overtreatment in distinct patients groups such as patients with early gastric cancer with favorable pathological characteristics and clinically negative nodes not suitable for endoscopic treatment because this early stage disease shows limited lymph node metastasis incidence and excellent overall survival. Considering that the D2 gastrectomy has a negative impact on the quality of life of gastric cancer patients due to the post-gastrectomy functional results, a concept of a more targeted lymph node dissection, when appropriate, is certainly appealing. It is yet to be proven whether sentinel lymph node navigation surgery can fulfill such expectations providing the appropriate balance between morbidity and oncological safety in selected gastric cancer patients

Simple excision and closure of a distal limb of loop colostomy prolapse by stapler device

Stomal prolapse is one of the common complications in transverse colostomy and can be managed conservatively in most cases; however, laparotomy and reconstruction of the stoma may sometimes be required, especially in case of irreducible colostomy prolapse. We have reported a simple local repair with reconstruction of the loop colostomy. We herein report a new more simple technique to avoid laparotomy and allow excision of the irreducible colostomy prolapse and complete closure of the distal limb of loop colostomy when no decompression is required in the distal limb of the stoma. In this procedure, the number of stapler and the time with blood loss for the operation can be saved

Usefulness of vessel-sealing devices combined with crush clamping method for hepatectomy: A retrospective cohort study

Background: Blood loss during resection of the hepatic parenchyma in hepatectomy can be minimized using vessel-sealing (VS) devices. Some sealing devices were retrospectively compared to evaluate the efficacy of each device for controlling blood loss, transection time and postoperative complications in hepatectomy as a cohort study. Methods: Between 2005 and September 2012, hepatectomy was underwent in 150 patients using one of three types of LigaSure™ (Dolphin Tip Laparoscopic Instrument, Precise or Small Jaw) or the Harmonic Focus or Ace ultrasonic dissecting sealer. Results were compared to crush-clamping alone as the control method by the historical study (n=81). Results: Irrespective of the vessel-sealing device used for underlying chronic hepatitis, blood loss, blood transfusion rate, operating time and transection time were significantly reduced in the VS group compared with controls (p<0.05). Rates of postoperative bile leakage and intra-abdominal abscess formation were significantly lower in the VS group than in controls (p<0.05). Comparing devices, LigaSure Small Jaw and Harmonic Focus showed lower blood loss, shorter transection time and reduced rates of post-hepatectomy complications, in turn resulting in shorter hospital stays (p<0.05). Tendencies toward uncontrolled ascites and bile leakage were only concern with the use of Harmonic Focus. Satisfactory surgical results were achieved using the sealing device for laparoscopic hepatectomy. Conclusions: The use of energy sealing devices improves surgical results and avoids hepatectomy-related complications. Adequate use of vessel sealers is necessary for safe and rapid completion of hepatic resection

Advanced trauma life support course for medical students. A new era?

IntroductionTrauma represents a major public health issue and is one of the leading causes of death and disability worldwide. A systematic approach toward dealing with trauma patients was facilitated through the ATLS program, which has become a milestone in trauma care. Our new ATLS course for medical students was set in motion in 2015. Our aim was to make medical students familiar with trauma patients interactively, through a program like ATLS, and here we present the results of this endeavor.MethodsA two-day ATLS-Medical Student (MS) course was offered from November 2015 to July 2018, and analysis was performed retrospectively on the data gathered over a three-month period through online questionnaires. Before graduating, 261 newly qualified medical doctors were interviewed and evaluated as part of the ATLS course.ResultsAfter the course, the vast majority of medical students (251 MSs; 96.16%) felt more capable of managing severely injured patients and 58% of students felt that the medical services they offered were better due to the ATLS training. Regarding the educational fee for the course, 56.7% of the students reported that they felt the fee of 100 euros was fair.DiscussionThe interactive format of the course, which differs from more traditional methods of teaching, has been endorsed by medical students. Though they lack clinical experience, that does not prohibit them from acquiring more specialized or specific knowledge, enabling them to excel. Most of the students improved their skillset either in theoretical knowledge, practical skills, or even in the emotional component of the course, i.e., dealing with treating a severely injured patient. It was decided that the program would be re-evaluated and extended to all Greek Medical Schools.ConclusionThe advantage of providing doctors with trauma training at the beginning of their careers is evident. For that reason, it was decided that the program would be re-evaluated and extended to all Greek Medical Schools

Evidence of functional deficits at the single muscle fiber level in experimentally-induced renal insufficiency

Chronic kidney disease patients present with metabolic and functional muscle abnormalities, called uremic myopathy, whose mechanisms have not yet been fully elucidated. We investigated whether chronic renal insufficiency (CRI) affects skeletal muscle contractile properties at the cellular level. CRI was induced surgically in New Zealand rabbits (UREM), with sham-operation for controls (CON), and samples were collected at 3 months post-surgery, following euthanasia. All protocols had University Ethics approval following national and European guidelines. Sample treatments and evaluations were blinded. Maximal isometric force was assessed in 382 permeabilized psoas fibers (CON, n=142, UREM, n=240) initially at pH7, 10oC (‘standard’ conditions), in subsets of fibers in acidic conditions (pH6.2, 10oC) but also at near physiological temperature (pH7, 30oC and pH6.2, 30oC). CRI resulted in significant smaller average CSA (~11%) for UREM muscle fibers (vs CON, P<0.01). At standard conditions, UREM fibers produced lower absolute and specific forces (i.e. normalized force per fiber CSA) (vs CON, P<0.01); force increased in 30oC for both groups (P<0.01), but the disparity between UREM and CON remained significant. Acidosis significantly reduced force (vs pH7, 10oC P<0.01), similarly in both groups (in UREM by -48% and in CON by -43%, P>0.05). For the first time, we give evidence that CRI can induce significant impairments in single psoas muscle fibers force generation, only partially explained by fiber atrophy, thus affecting muscle mechanics at the cellular level
