RESUMEN
INTRODUCTION: Haemobilia caused by pseudoaneurysms of the right hepatic or cystic artery is rare. Haemobilia classically causes gastro-intestinal hemorrhage, jaundice and upper abdominal pain. PRESENTATION OF CASE: A 76-year old female underwent laparoscopic cholecystectomy because of a severe acute on chronic cholecystitis. A massive arterial bleeding occurred during surgery, which was controlled with hemoclips. Approximately one week after surgery the patient developed severe colic pains and cholestatic liver enzyme alterations. Endo-ultrasound showed normal-width bile ducts, however during a subsequent ERCP haemobilia was observed. On computed tomography a pseudoaneurysm of the right hepatic artery was seen. Selective embolization was initially successful, however, a rebleed was observed two weeks later and a 6 × 50 mm Viabahn stent graft was placed in the right hepatic artery uneventfully. The patient remained free of complaints during 3-years of follow-up. DISCUSSION: Pseudoaneurysms of the cystic or hepatic arteries are described to be cholecystectomy or cholecystitis related. The etiology of the pseudoaneurysm in this case can be inflammatory or iatrogenic. Embolization is the golden standard in pseudoaneurysm treatment. Stent graft implantation has not been frequently described as an alternative option to surgery after a failed attempt of embolization. CONCLUSION: This case report presents a probable cholecystitis related pseudoaneurysm of the right hepatic artery, which caused haemobilia after cholecystectomy. The pseudoaneurysm was successfully eliminated with a stent graft after embolization had failed. Stent grafts should be considered a minimal invasive and effective alternative after failed embolization of a pseudoaneurysm.
RESUMEN
The guidelines for metastatic colorectal cancer crudely state that the best local treatment should be selected from a 'toolbox' of techniques according to patient- and treatment-related factors. We created an interdisciplinary, consensus-based algorithm with specific resectability and ablatability criteria for the treatment of colorectal liver metastases (CRLM). To pursue consensus, members of the multidisciplinary COLLISION and COLDFIRE trial expert panel employed the RAND appropriateness method (RAM). Statements regarding patient, disease, tumor and treatment characteristics were categorized as appropriate, equipoise or inappropriate. Patients with ECOG≤2, ASA≤3 and Charlson comorbidity index ≤8 should be considered fit for curative-intent local therapy. When easily resectable and/or ablatable (stage IVa), (neo)adjuvant systemic therapy is not indicated. When requiring major hepatectomy (stage IVb), neo-adjuvant systemic therapy is appropriate for early metachronous disease and to reduce procedural risk. To downstage patients (stage IVc), downsizing induction systemic therapy and/or future remnant augmentation is advised. Disease can only be deemed permanently unsuitable for local therapy if downstaging failed (stage IVd). Liver resection remains the gold standard. Thermal ablation is reserved for unresectable CRLM, deep-seated resectable CRLM and can be considered when patients are in poor health. Irreversible electroporation and stereotactic body radiotherapy can be considered for unresectable perihilar and perivascular CRLM 0-5cm. This consensus document provides per-patient and per-tumor resectability and ablatability criteria for the treatment of CRLM. These criteria are intended to aid tumor board discussions, improve consistency when designing prospective trials and advance intersociety communications. Areas where consensus is lacking warrant future comparative studies.

This study aimed to investigate whether pulmonary shunt grade on transthoracic contrast echocardiography (TTCE) predicts the size of pulmonary arteriovenous malformations (PAVMs) on chest computed tomography (CT) and subsequent feasibility for transcatheter embolotherapy. We prospectively included 772 persons with possible or definite hereditary haemorrhagic telangiectasia, who underwent both TTCE and chest CT for screening of PAVMs. A quantitative three-point grading scale was used to classify the pulmonary shunt size on TTCE (grade 1-3). Transcatheter embolotherapy was performed for PAVMs deemed large enough for endovascular closure on chest CT. TTCE documented pulmonary shunting in 510 (66.1%) patients. The positive predictive value of a pulmonary shunt grade 1, 2 and 3 on TTCE for presence of PAVMs on chest CT was 13.4%, 45.3% and 92.5%, respectively (p<0.001). None of the 201 persons with a pulmonary shunt grade 1 on TTCE had PAVMs on chest CT large enough for transcatheter embolotherapy, while 38 (25.3%) and 123 (77.4%) individuals with a pulmonary shunt grade 2 and 3 on TTCE, respectively, underwent endovascular closure of PAVMs. Pulmonary shunt grade on TTCE predicts the size of PAVMs on chest CT and their feasibility for subsequent transcatheter embolotherapy. Chest CT can be safely withheld from all persons with a pulmonary shunt grade 1 on TTCE, as any PAVM found in these subjects will be too small for transcatheter embolotherapy.

STUDY DESIGN: A prospective single-arm trial. OBJECTIVE: To investigate whether dynamic isolated resistance training of global lumbar extensor muscles leads to changes in lumbar multifidus (LM) morphology in terms of cross-sectional muscle, and, if so, whether these changes are associated with observed changes in self-experienced functional status of chronic nonspecific low back pain (CNSLBP). SUMMARY OF BACKGROUND DATA: LM morphology is associated with the recurrence of CNSLBP. METHODS: Sixteen male patients underwent a dynamic isolated resistance-training program for the lower back muscles of approximately 10 sessions in 12 weeks. In the next 12 weeks, frequency of training was tailored to the patients' need. Participants underwent lumbar magnetic resonance imaging at baseline (T0), after 12 weeks (T12), and after 24 weeks (T24). Functional cross-sectional area was obtained by analyzing the magnetic resonance images. Functional status was assessed using the patient-specific functional scale, Roland-Morris disability questionnaire, and global perceived effect scale. RESULTS: Roland-Morris disability questionnaire and patient-specific functional scale scores showed significant and clinically relevant improvements between baseline and T12, with 44% and 39%, respectively. Between T12 and T24, these scores did not change significantly. Seven participants (44%) reported clinically relevant improvements in global perceived effect at T12. At T24, 1 more participant reported a relevant global perceived effect improvement, whereas 2 participants (13%) reported worsening of their condition. The magnetic resonance imaging analysis showed minor nonsignificant changes in functional cross-sectional area. CONCLUSION: Our study shows that 10 weeks of dynamic isolated training of the lumbar extensors, once a week, leads to clinically relevant improvements in functional status of men with CNSLBP, without accompanying improvements in functional cross-sectional area of LM. These findings suggest that improvement in LM morphology is not a critical success factor in restoring functional status of patients with CNSLBP, at least in the short term (6 mo).
