Insights
Laparoscopy (L) is a more accurate diagnostic tool for hepatic cirrhosis (HC) than hepatic biopsy by needle (HBN). L offers superior diagnostic yield and additional clinical insights, making it the preferred initial diagnostic method for HC.
Area of Science:
- Hepatology
- Diagnostic Imaging
- Gastroenterology
Background:
- Hepatic cirrhosis (HC) diagnosis relies on accurate methods.
- Needle biopsy has limitations in sample adequacy and contraindications.
Purpose of the Study:
- To compare the diagnostic performance of laparoscopy (L) and hepatic biopsy by needle (HBN) for hepatic cirrhosis.
- To evaluate the additional diagnostic benefits of laparoscopy beyond simple biopsy.
Main Methods:
- Analysis of 316 patients with proved hepatic cirrhosis who underwent laparoscopy.
- Comparison of diagnostic accuracy between laparoscopy and hepatic biopsy by needle.
- Follow-up of 96 patients until death, with 54 undergoing necropsy.
Main Results:
- Laparoscopy achieved 96.6% diagnostic accuracy for HC, compared to 74.7% for HBN.
- HBN failed to confirm diagnosis in 25.3% of cases due to insufficient samples.
- Laparoscopy identified coexisting pathologies and signs of portal hypertension, unavailable with HBN.
Conclusions:
- Laparoscopy is the preferred initial diagnostic method for hepatic cirrhosis due to its higher accuracy and comprehensive assessment.
- HBN is reserved for ambiguous cases or specific etiological investigations.
- Non-invasive imaging techniques do not currently replace laparoscopy or HBN for precise HC diagnosis.
Abstract:
316 cases of proved hepatic cirrhosis (HC) which underwent Laparoscopy (L) were analysed. In 94 cases, hepatic biopsy by needle (HBN) was also practised under laparoscopic view, 96 cases were controlled until death, with a follow-up of almost 90 months. In 54 of these, there is a complete necropsy study. The performance in diagnosis of cirrhosis, L and HBN are compared separately. L gave the exact result of 96.6% and HBN 74.7%. HBN commonly practised with a Menghini needle (1.2 or 1.4 mm) as it is one that produces less complications, gives and insufficient sample, which determines that in 25.3% of the cases under biopsy, the HC diagnosis could not be proved, while L only fails in this aspect, in 3.38%. To this disadvantage of HBN, we must add another negative factor, the frequency which HBN can not be practised due to prothrombin under 50%, which nevertheless is not an obstacle for practising an L. In this series we have not reported any deaths with this two techniques. L has the additional advantage to contribute other useful data which can not be obtained with HBN alone. as revealing signs of portal hypertension, and hepatobiliary or peritoneal pathology which can coexist with HC. Due to this reasons, in the study of HC, we preferred as the first method of diagnosis, L, instead of HBN. When through this endoscopy we obtain the typical aspect, we omit adding HBN, which we only practised in doubtful cases of not very nodular livers (glabra cirrhosis) or when a probable post-hepatis, Wilson disease or hemochromatosis is being investigated. In the present conditions, we believe that the new methods of diagnosis "of non invasive images" can not substitute L or HBN in precising the diagnosis of HC.
