Percutaneous catheter drainage of uncomplicated amoebic liver abscess: prospective evaluation of a clinical protocol for catheter removal and the significance of residual collections.

INTRODUCTION: Patients with amoebic liver abscess (ALA) may require percutaneous catheter drainage (PCD). Once the PCD output is substantially reduced or has ceased along with clinical recovery, residual collections on radiological evaluation may concern the treating physicians. The prevalence and significance of such collections is unknown, and the subsequent approach how to tackle them is unclear. METHODS: Consecutive patients with one or more uncomplicated ALAs requiring drainage were prospectively enrolled from 3 hospitals and managed based on a standard approach. Catheter removal was attempted after the patients fulfilled all 4 of the following criteria: disappearance of abdominal pain, absence of fever for at least 48 h, an improving trend of TLC (documented on 2 consecutive reports), and catheter drain output of < 10 ml/day for at least 2 consecutive days. RESULTS: A total of 110 patients (mean age 46.6 ± 10.5 years, 93.6% males, 89.1% alcoholics) underwent PCD placement; 69 patients (69/110; 62.7%) met all 4 criteria within 5 days of PCD placement (optimal response) and had an uncomplicated course. Patients with suboptimal responses (41/110; 37.3%) were evaluated for local and systemic complications; the appearance of fresh collections (5/110; 4.5%), abscess rupture (2/110; 1.8%), bile leakage (3/110; 2.7%), cholangitis (2/110; 1.8%), thrombophlebitis (2/110; 1.8%) and hospital-acquired infections (2/110; 1.8%) were diagnosed and treated accordingly. Ultimately, PCD removal (based on the fulfilment of all 4 criteria) was universally successful after a median of 5 days (IQR, 4-9 days). None of the patients had symptom recurrence after PCD removal, although residual collections were still seen in 97.3% of patients at the time of PCD removal and in 92.1% and 84.9% of patients available for follow-up at 1 and 3 months, respectively. CONCLUSION: Based on our clinical protocol, PCD removal in ALA can be successfully expedited even in the presence of residual collections. An inability to fulfill all 4 criteria within 5 days of PCD placement warrants further evaluations for local and systemic complications that require additional therapeutic measures.

Perception of Illness and Its Association with Treatment Willingness in Patients with Newly Diagnosed Nonalcoholic Fatty Liver Disease.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease of immense public health relevance. Understanding illness perceptions in the NAFLD population will provide sound scientific evidence for planning high-quality patient-centered care and implementing effective interventions. The Brief Illness Perception Questionnaire (BIPQ) is a robust psychometric tool to systematically assess the dimensions of illness perceptions in various chronic ailments. METHODS: In a cross-sectional study enrolling patients with newly diagnosed NAFLD, the sociodemographic, anthropometric, biochemical, and radiological determinants of enhanced illness perceptions (measured by the BIPQ score) were investigated using univariate and multivariable binary logistic regression analyses. Finally, the association between individual domains of the BIPQ and willingness to participate in comprehensive medical management was explored. RESULTS: In total, 264 patients (mean age 53 ± 11.9 years, 59.8% males) were enrolled in the final analysis. The mean and median BIPQ scores in the study population were 30.3 ± 12.8 and 31.0 (IQR, 22.0-40.0), respectively. The variables having a significant independent association with heightened perceptions (BIPQ > 31) were family history of liver disease (aOR, 5.93; 95% CI, 1.42-24.74), obesity (aOR, 3.33; 95% CI, 1.57-7.05), diabetes mellitus (aOR, 2.35; 95% CI, 1.01-5.49), and transaminitis (aOR, 2.85; 95% CI, 1.42-5.69). Patients with a higher level of illness perceptions (31.6 ± 12.9 vs 27.8 ± 12.3, p = 0.022) were more likely to express a willingness to participate in the comprehensive management plan, with 3 of the 8 domains (consequence, identity, and treatment control) mainly affecting willingness. CONCLUSION: A family history of liver disease, obesity, diabetes, and transaminitis were independently associated with increased illness perceptions. A belief in serious consequences, a strong illness identity, and higher perceived treatment control were significantly associated with the willingness to undergo comprehensive care for NAFLD.
