Introduction Infection of transjugular intrahepatic portosystemic stent shunt (TIPSS) called ‘Tipsitis’ has been reported but appears unusual. We report here our experience of patients who were diagnosed to have Tipsitis at our centre. Methods Retrospective single centre study. Patients identified from a dedicated data base. Patients with TIPSS with otherwise unexplained sustained bacteraemia were included. Results Over 14 years of age, of 785 patients with TIPSS, eight (1%) had Tipsitis. Indication for TIPSS: variceal bleed, seven; refractory ascites, one. Child–Pugh score: 8.3 (1.4). Seven patients had overlapping stents in situ. Duration to Tipsitis: 21.6 (7.1) months. At diagnosis, TIPSS was occluded in four and patent in three. Tipsitis developed within 2 weeks of shunt interventions in two patients and was owing to development of bilio-venous fistula in one. The organisms identified were: Lactobacillus rhamnosus, Escherichia coli, Enterobacter cloacae, Enterococcusfaecium and Staphylococcus aureus. Median duration of antibiotic therapy: 3 (0.3–3) months. Symptoms initially resolved in all but one. Symptoms recurred in three and this was related to premature cessation of antibiotics in two. Five patients died at a median 1.3 (0.3 to 33) months after Tipsitis with Tipsitis contributing to death in three. Conclusion Tipsitis is a rare but serious problem. It should be suspected in patients with TIPSS and unexplained sustained bacteraemia. Shunt interventions, where TIPSS is inserted for variceal bleed, and use of overlapping shunts at TIPSS insertion may be risk factors for its development. Prolonged antibiotics are usually required but Tipsitis may recur despite apparently successful treatment.

Aliment Pharmacol Ther 28, 294–303Summary: Background  Bleeding from ectopic varices is uncommon but can be difficult to manage.Aim  To report our experience of the use of transjugular intrahepatic portosystemic stent shunts (TIPSS) in the management of uncontrolled bleeding from ectopic varices.Methods  A retrospective study of patients who had TIPSS for bleeding ectopic varices. Patients were selected from a dedicated data base.Results  Over 14 years, of 750 TIPSS insertions, 28 patients had TIPSS for bleeding ectopic varices (Child–Pugh score: 8.8 ± 1.8). Varices were rectal (12), stomal (8), duodenal (4) and at other sites (4). Concomitant variceal embolization was performed in five. Portal pressure gradient fell from 18.2 ± 6.4 to 7.2 ± 3.5 mmHg. TIPSS achieved haemostasis in six of nine patients who presented with active bleeding. Five patients rebled from ectopic varices. This was related to shunt dysfunction in two and responded to shunt interventions. Three patients rebled despite a functional shunt. Of these, thrombin controlled bleeding in one. Eight patients developed hepatic encephalopathy post‐TIPSS.Conclusions  Transjugular intrahepatic portosystemic stent shunt is a safe and effective treatment for bleeding ectopic varices. Rebleeding from ectopic varices related to shunt dysfunction responds to shunt intervention. A significant proportion of patients have rebleeding despite a patent shunt, when other adjunctive measures like thrombin injection may be tried.

Background: Post-transjugular intrahepatic portosystemic stent shunt (TIPSS) hepatic encephalopathy (HE) can occur in up to one third of patients. In 5%, this can be refractory to optimal medical treatment and may require shunt modification. The efficacy of shunt modification has been poorly studied. Aims: To evaluate the efficacy of and natural history following TIPSS modification for treatment of refractory HE. Methods: From a dedicated database, we selected and further studied patients who had TIPSS modification for refractory HE. Results: Over a 14 year period, of 733 TIPSS insertions, 211(29%) patients developed HE post-TIPSS. In 38 patients, shunt modification (reduction (n = 9) and occlusion (n = 29)) was performed for refractory HE. Indications for TIPSS were: variceal bleeding (n = 32), refractory ascites (n = 5), and other (n = 1). Child’s grades A, B, and C were noted in 11%, 47%, and 42% of cases, respectively. HE improved in 58% of patients and remained unchanged or worsened in 42%, with similar results for occlusions and reductions. Following shunt modification, variceal bleeding recurred in three patients and ascites in three. Twenty five patients have died (liver related in 15) at a median duration of 10.2 months. Three patients died due to procedure related complications following shunt occlusions (mesenteric infarction (n = 2) and septicaemia (n = 1)). Median survival of patients whose HE did not improve following shunt modification was 79 days compared with 278 days in patients whose did (pConclusions: TIPSS modification is a useful option for patients with refractory HE following TIPSS insertion. Due to the significant risk of iatrogenic complications with shunt occlusions, shunt reduction is a safer and preferred option.
