The document discusses tips for managing ascites, including performing large volume paracentesis with albumin and continuing diuretics if renal sodium excretion is over 30 mmol/day. It also discusses using non-selective beta-blockers and transjugular intrahepatic portosystemic shunts (TIPS) to treat refractory ascites, noting that TIPS significantly reduces hepatic encephalopathy compared to large volume paracentesis alone. TIPS is an effective option for controlling ascites but carries a higher risk of hepatic encephalopathy compared to large volume paracentesis.

Biliary complications after liver transplantationApollo Hospitals
Liver transplantation (LT) has become the established means of treating patients with end-stage liver disease. However, biliary complications remain a significant cause of postoperative morbidity and possibly mortality. Biliary strictures and leaks are the most common complications following liver transplantation. The incidence of biliary tract complications after orthotopic LT (OLT) varies from 11% to 34%. The reported incidence of biliary complications is 5–15% after deceased donor liver transplantation (DDLT) and 20–34% after right lobe living-related liver transplant (LRLT). There are several predisposing risk factors for development of biliary complications post transplant with a higher risk in LRLT compared to DDLT. Bile duct strictures occur in 4–13% of patients after DDLT and account for approximately 40% of all biliary complications where as the incidence of biliary leaks after LT ranges between 2% and 25%. Biliary strictures after liver transplantation have been classified as anastomotic strictures (AS) and non-anastomotic strictures (NAS). Most bile leaks and strictures can be resolved nonoperatively with early endoscopic intervention. Endoscopic retrograde cholangiopancreatography (ERCP) is the first line treatment at our center for both bile leaks as well strictures. However, in spite of excellent results surgery is required in small proportion of patients.
Portal biliopathy is defined as abnormalities in the intrahepatic and extrahepatic biliary tract, gallbladder and cystic duct secondary to portal hypertension

Acute pancreatitis is a common medical problem. Initial phase of acute pancreatitis is characterized by inflammation. This is caused by release of cytokines and other pro inflammatory mediators. These further cause vasodilatation, intravascular volume depletion, and end organ hypoperfusion. The etiology can be varied but common causes are biliary (stone in CBD) and alcohol. Other causes are drugs, infections, trauma, idiopathic, post ERCP etc. Patients with severe pancreatitis have high risk of mortality (10%) which can go upto 30% if necrosis gets infected, which occurs in about 40% patients. Further, persistent organ failure increases the mortality up to 34–55% as compared to 0.3% with transient organ failure. Traditionally as per Atlanta classification, acute pancreatitis has been classified as mild or severe depending upon organ failure or local complications. Acute pancreatitis is a hyper-catabolic state. Moreover some of these patients may be malnourished to begin with (alcoholics). Thus their nutritional requirements are much more than ordinary person. There are good quality studies available to show that in absence of cholangitis, there is no benefit of doing early ERCP. Also, technically it is more difficult to do in such situations, and procedure related complication may be more. If in doubt, it may be worthwhile to do endoscopic ultrasound to document the presence of CBD stone before attempting to cannulate the CBD.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

3. Ascites
• Ascites is the MC cause of decompensation in LC, as 5-10% of pts with compensated cirrhosis per year
develop this complication.1
• The appearance of ascites heralds a poor prognosis, as the five-year survival drops from about 80% in
compensated pts to about 30% in pts with DLC and ascites.2
• Refractoriness of ascites is associated with a poor prognosis, with a median survival of about six months.3

4. Refractory ascites (ra)
• In about 5-10% of cirrhotic pts per year and as liver disease progresses, response to sodium restriction
and diuretics diminishes, leading to RA.[1]
• RA is defined by the failure to mobilize ascites despite high-dose diuretics, typically about 400 mg/day
spironolactone and 160 mg furosemide or equivalent dose of loop-acting diuretic.[1]
• Ascites is also considered to be refractory when effective doses of diuretics cannot be used because of
development of diuretic-associated complications. RA is often a/with dilutional hyponatremia, type 2
HRS, SBP, and muscle wasting.[2]

6. Management of Refractory Ascites (summary)
• Large-volume paracentesis with albumin:
• Diuretics in patients with refractory ascites: continue if renal sodium excretion >30 mmol/day
• Non-selective beta-blockers in patients with refractory ascites: with caution
• Transjugular intrahepatic portosystemic shunts: HE significantly reduced from 50 % to about 18%
• Wang Q et al,2017. Eight mm covered TIPS does not compromise shunt function but reduces HE in
preventing RVH.
• Sauerbruch et al. 2015. Prevention of rebleeding from EV in pts receiving small-diameter stents vs.
hemodynamically controlled medical therapy.
• Indeed, underdilated 10 mm stent grafts passively expand to almost the full diameter within 1–6 weeks.
The final messages from Metaanalysis can be summarised as follow:
i) TIPS controlled ascites better than LVP
ii) TIPS is followed by a greater incidence of HE
iii) However, discrepant results were obtained with respect to survival.
Currently available data suggest that TIPS improves survival compared to LVP in pts with recurrent ascites, but it
does not in those with refractory ascites.

➢ a1-adrenergic agonist: midodrine
➢ a2-adrenoceptor agonist : clonidine
➢ Combinations of midodrine with either clonidine
➢ Antagonist of vasopressin V2-receptors: tolvaptan
➢ Terlipressin
➢ Octreotide and albumin
➢ Combined midodrine/rifaximin/diuretics
➢ Alfapump®: significant reduction of the number and volume of paracentesis, significantly improved
quality of life and nutritional parameters.AE: AKI
Inhibition of the AVP V2 receptor reduces the number of
aquaporin-2 water channels in the renal collecting duct and
decreases the water permeability of the collecting duct.
Collectively, agents that competitively block ADH action and
increase water excretion are called aquaretics.

10. Transjugular intrahepatic portosystemic shunt
(TIPSS): Introduction
• TIPS involve creation of a low-resistance channel between
the hepatic vein and the intrahepatic portion of the
portal vein (usually the right branch) using angiographic
techniques.
• The tract is kept patent by deployment of an expandable
metal stent across it, thereby allowing blood to return to
the systemic circulation.
• A TIPS is placed to reduce portal pressure in pts with
complications related to PHTN.[1,2]

• Intravenous heparin is given for prevention of shunt thrombosis (bolus dose of 2500–5000 U
followed by constant infusion for 1–2 weeks, targeted at an aPTT of 60–80 seconds.
• A color Doppler USG is obtained 24 hours after the procedure to show shunt patency.
• It is usually repeated one week later if it is an uncovered stent or one month later if it is covered.
After that, if there are no complications, the USG is repeated 3 months later and then every 6 months
until the clinical outcome.

15. Are blood products routinely required during
TIPS placement?
• FFP, or pro-haemostatic agents are not required in cirrhotic pts undergoing TIPS, irrespective of
INR value (1,2).
• Although the threshold of platelet count needed to ensure normal primary haemostasis in cirrhosis is
not clearly defined, the 50X109/L cut-off can be utilized for platelets infusion before TIPS (3).

17. EARLY EVENTS: Bacteriemia
• Bacteriemia after TIPS (defined by fever >38.5°C, or leucocytosis >15.000 / ul and positive blood
cultures) ranges between 2-25%(2-4,6) and in a prospective RCT was not influenced by antibiotic
prophylaxis (1)
• A longer duration of procedure, multiple stenting and the maintenance of a central venous line
are a/with a higher risk of infection after TIPS.
• In pts with uncomplicated procedure, the transjugular venous access should be removed at the end of the
intervention (1,5).
• A single dose of long acting cephalosporin ↓ the incidence of bacterial infection (20% to 2.6%)
justifying its use in anticipated complex procedures (2).

18. LATE EVENTS: Endotipsitis
• Defined by the presence of sustained bacteriemia a/with the evidence of thrombus or vegetations
inside the TIPS. This clinical condition is rare (1%).
• Early endotipsitis (< 120 days of the procedure) is usually related to Gram-positive organisms and the
antibiotic therapy must be long-lasting (at least 3 months) to avoid recurrence (1).
• In pts with uncontrolled or recurrent infection LT should be considered(2).
• There is no evidence for adopting long-term prophylaxis for the prevention of endotipsitis.

The term “endotipsitis” was proposed by Sanyal and Reddy[3], who defined it as: (1) the presence of continuous
bacteremia indicating an infectious focus in continuity with the venous circulation and (2) failure to find an alternate
source of infection despite an extensive search.
18
19. Hepatic encephalopathy
• HE is one of the major complications of TIPS. The incidence of overt episodic or recurrent HE post-
TIPS varies between 15 and 67% in a 2-year follow-up. The incidence of persistent overt HE is
around 8% (1) and that of covert HE around 35% (2-9,12,13).
• Prophylaxis of post-TIPS HE with either lactulose or rifaximin is not routinely recommended (9).
• Stent lumen reduction or occlusion is effective in case of persistent overt post-TIPS HE (10,11).
References are present at the end of the slides. 19
20. Contraindications to TIPS positioning
• The absence of vascular accesses represents the only technical CI to TIPS (1).
• The presence of PVT resulting in a portal cavernoma is not an absolute CI in presence of a “portal”
landing zone with adequate flow and calibre to receive the device (2,3)

S. Fagiuoli, “Consensus conference on TIPS management" 2017
Clinical contraindications to TIPS placement are:
• Advanced liver disease (CP > 11, serum bilirubin > 5 mg/dl, MELD >18) (4).
• Severe organic renal failure (serum creat > 3 mg/dl)
• Heart failure
• Severe porto-pulmonary HTN (mPAP>45mmHg)
• Recurrent or persistent overt HE grade > 2 (WH scale) despite adequate RX
• Uncontrolled sepsis
20
21. • Relative technical CIs are anatomical conditions a/with a reduction in technical success rate or with
an ↑ risk of complications, such as liver tumours, the presence of multiple hepatic cysts.
The clinical appropriateness of TIPS positioning should be evaluated on a case-by-case
basis according with the relevance of the indication and the presence of general CIs.
Indeed, in the context of a life-threatening condition such as AVH, a broader range can be
adopted (CP C score < 14).
21
22. TIPS: Bare stent Vs PTFE-covered stent
• A major complication after TIPS insertion using bare stent grafts is the development of HE, which
can occur in up to 50% of pts.[1,2]
• The incidence of this complication can be significantly reduced to about 18% with the use of PTFE-
covered stent grafts of 8 mm,[3] a result confirmed by a recent RCT comparing 8 mm and 10mm
stent grafts.[4]
• Dysfunction of TIPS with bare stent grafts because of stent thrombosis and stenosis can develop in
up to 80% of cases.[1] This complication has been significantly reduced with the use of PTFE-covered
stents.[5]
References are present at the end of the slides. 22

improved the shunt patency, but also significantly ↓the risk of death. Additionally,
the risk of HE was not ↑ by the use of covered stents.
23References are present at the end of the slides.
24. TIPS in mx of refractory ascites (ra)
• The goal of TIPS creation in the case for RA is to reduce the portosystemic pressure gradient to <12
mm Hg.[1]
• TIPS improves ascites via increased natriuresis through reduction in both proximal tubular sodium
reabsorption and activity in the RAAS.[2]
• Notably, even after TIPS creation, pts must continue to restrict their sodium intake, and a majority of pts
will require low dose diuretics to maintain an ascites-free state.

25. Controlled studies and meta-analysis
• Numerous RCTs have compared LVP and TIPS.
• The clinical effects of TIPS with bare stents in pts with refractory or recurrent ascites have been
assessed in 6 prospective RCTs (next slide),[1-6] whose main features are reported.
• Based on these RCTs, 7 meta-analyses were performed.[7-13]
References are at the end of the slides
The final messages can be summarised as follow:
i) TIPS controlled ascites better than LVP,
ii) TIPS is followed by a greater incidence of HE.
However, discrepant results were obtained with respect to survival.
Note: Recurrent or recidivant ascites is a severe stage prior to further progression to refractory ascites and is defined
as ascites that recurs on at least 3 occasions within a 12-month period despite prescription of dietary sodium
restriction and adequate diuretic dosage.

27. Summary
• Thus, currently available data suggest that TIPS improves survival compared to LVP in pts with
Recurrent Ascites, but it does not in those with RA.
• A careful selection of pts is also crucial to maximise the beneficial effects of TIPS, as TIPS can even
be detrimental in pts with the most advanced stages of cirrhosis, such as those belonging to CP C.[1]

randomized trial. French Group of Clinicians and a Group of Biologists. J Hepatol 1996;25:135–144.
28. Predictor of survival
• A risk score (R) system based on SCr, INR, serum bilirubin and aetiology of cirrhosis has been
proposed to predict survival after TIPS insertion for RA.[3] Pts with R > 1.8 had a median survival of
3 months or less. This model was superior to both the CP classification, as well as the CP score, in
predicting survival.
• Another simple predictor of survival suggested for pts receiving TIPS for RA consists of the
combination of serum bilirubin and platelet count.[1]
• Another factor that seems to influence mortality is the number of TIPS procedures performed in a
centre, as the risk of inpatient mortality is lower in hospitals performing ≥20 TIPS per year.[2]

29. Models used for prediction of post–tips survival
• Numerous models have been used to predict post-TIPS survival (for any indication), of which the CP
score and MELD score have been the most used.[1]
• Of the two, the MELD score has shown to be superior to CP score as a predictor for short-term
outcomes.[2]
• In a meta-analysis by Salerno et al, a MELD score between 11 and 19 was found to have a significant
survival benefit in pts who underwent TIPS versus pts who underwent LVP.[3]

30. • In addition, a survival benefit for TIPS was seen across all MELD categories.
• Furthermore, in a recent single-center study of 100 pts who underwent TIPS placement, with an
expanding covered stent, the 1-year survival rate for a MELD score less than 15, 15 to 18, and greater
than 18 was 84%, 67%, and 54%, respectively.[1]

31. • Currently, no RCTs have evaluated TIPS for RA in pts with a MELD score greater than 20.
• As such, each pt with RA should be evaluated carefully by looking at other clinical factors that can
adversely affect outcomes. These factors include older age, high bilirubin, history of HE, and low sodium
concentration.[1]
• In those without severe hyperbilirubinemia or HE, TIPS may be considered in highly selected
individuals on a case-by-case basis and by individual assessment of risks and benefits.

➢TIPS in refractory/recidivant ascites/HRS/HH ?
➢TIPS in HPS/SOS?
➢TIPS in PVT ?
➢TIPS in NCIPH ?
➢TIPS in BCS ?
34. TIPS in refractory/recidivant ascites/HRS/HH ?
• TIPS is more effective than conservative/medical treatment to resolve refractory/recidivant
ascites, greatly reducing the need of paracentesis. TIPS should be considered in all pts with
refractory/recidivant ascites.
• TIPS is effective to treat type-II HRS associated to refractory/recidivant ascites. Cannot be
recommended in unselected patients with type-I HRS .
• TIPS can be considered in refractory hydrothorax (RH) aiming at resolution of hydrothorax and
reduction in number of thoracentesis. The effect of TIPS on survival are still not clearly defined in RH.
Thus, the final decision to insert a TIPS should be reached on an individual pt basis after a
multidisciplinary clinical evaluation.

35. TIPS in HPS/SOS?
• At present, there is no sufficient evidence to support the use of TIPS for the treatment of
hepatopulmonary syndrome.
• TIPS is not indicated in Sinusoidal Occlusion Syndrome in Bone Marrow Transplanted Patients, but
may be considered in individual basis in Solid Organ Transplant Recipient as stand-alone treatment or as
bridge to liver transplantation in a setting of multidisciplinary evaluation .
S. Fagiuoli, R. Bruno, and V. W. Debernardi, “Consensus conference on TIPS management: Techniques, indications, contraindications,” Digestive and Liver Disease, vol. 49, no. 2, pp. 121–137, 2017.
36. TIPS in PVT ?
• TIPS is feasible in pts with PVT with and without cirrhosis, but it bears higher failure and
complication rates when portal cavernoma, fibrous transformation of the main portal vein or
intrahepatic branches thrombosis, are present .
• Extension of the TIPS stent into the portal or SMV should be considered when recanalization of
PV/SMV is incomplete and the pt is not a LT candidate.
• TIPS can be considered to treat PVT in both cirrhotic and non-cirrhotic pts with progression of
thrombosis despite adequate anticoagulant treatment, or when there is an absolute CI to
anticoagulation, or with no response after a maximum of 6 months of anticoagulation treatment.

37. TIPS in NCIPH ?
• TIPS can be considered in NCIPH, applying the same indications utilized for the management of
portal hypertensive complications..
• Caution is needed in pts with refractory ascites, kidney failure and comorbidities.
S. Fagiuoli, R. Bruno, and V. W. Debernardi, “Consensus conference on TIPS management: Techniques, indications, contraindications,” Digestive and Liver Disease, vol. 49, no. 2, pp. 121–137, 2017.
38. TIPS in BCS ?
• In BCS pts, in a stepwise approach, TIPS with covered stent is indicated in case of failure of
anticoagulation (and angioplasty when feasible), represented by persistent ascites, AKI or elevated
transaminases .
• Listing for LT should be considered in case of a prognostic index score greater than 7 in pts candidate to
TIPS for BCS.
• When TIPS is attempted to treat hyper acute BCS with ALF presentation, the listing process for LT
should not be delayed.
BCS-TIPS PI (only for patients who underwent TIPS procedure): age × 0.08 + bilirubin × 0.16 + INR × 0.63[1].

124 patients. Gastroenterology. 2008;135:808–815.
40. History of TIPS
• The origins of TIPS date back to the 1960s with inadvertent portal access during the early years of transjugular cholangiography.
• In 1969, Rösch et al reported portal venography via a transjugular approach and discussed the potential of a “radiologic portocaval
shunt.” This was subsequently followed by animal experiments, initially with tract dilation utilizing dilators and then balloons.
• In 1982, Colapinto et al performed the first human balloon-dilated transjugular portosystemic shunt.
• However, it was in 1988 that the first human clinical procedure of a TIPS utilizing a metallic stent was documented (Palmaz stent) by
Goetz Richter (Freiburg, Germany).
• Subsequently, in the early to mid-1990s there was widespread clinical use of TIPS utilizing bare-metal stents. Selfexpanding stents
predominated as the primary stent utilized during TIPS (particularly the Wallstent, Boston Scientific, Natick, Massachusetts, United
States).
• In the second half of the 1990s, animal experimentation on covered stents using silicone coating and e-PTFE showed favorable
patency results for e-PTFE covered stents.
• Again, investigators at the Dotter Institute described a partly covered self-expanding stent, which the author believes has remarkable
resemblance to the currently commercially available Viatorr stent (Gore and Associates, Flagstaff, Arizona, United States).
• In the early 2000s, early human e-PTFE covered stent grafts for TIPS creation showed favorable and safe results with improved TIPS
patency.
• Finally, a decade ago (2003–2004) the Viatorr stent became commercially available in the United States and widespread utilization of
this e-PTFE covered stent grafts for TIPS occurred .
