Summary
Indocyanine green (ICG) fluorescence navigation aids laparoscopic hepatectomy for liver cancer recurrence. This method enhances tumor visualization during surgery, improving outcomes for patients with complex surgical histories.
Area of Science:
- Hepatobiliary surgery
- Surgical oncology
- Minimally invasive surgery
Background:
- Hepatocellular carcinoma (HCC) recurrence necessitates surgical intervention, often complicated by previous abdominal surgeries.
- Laparitic hepatectomy (LRH) offers benefits but requires precise tumor localization, especially in cases of recurrent disease.
- Indocyanine green (ICG) fluorescence has shown promise for intraoperative tumor visualization in liver cancer.
Observation:
- A 73-year-old male with a history of multiple laparotomies for HCC presented with liver recurrence.
- Laparoscopic repeat hepatectomy (LRH) was planned using an ICG fluorescence navigation system.
- ICG dye was administered intravenously two days prior to the surgical procedure.
Findings:
- Intraoperative ICG fluorescence provided clear visualization of the recurrent HCC in the lateral liver segment.
- The ICG fluorescence navigation system facilitated precise tumor identification and resection during laparoscopic surgery.
- Laparoscopic partial liver resection (S3) was successfully completed with a short operation time (197 minutes) and minimal blood loss (30 mL).
Implications:
- ICG fluorescence navigation is a valuable tool for enhancing intraoperative visualization in laparoscopic hepatectomy for recurrent liver cancer.
- This technique can improve surgical precision and potentially reduce complications in patients with challenging surgical histories.
- The successful application of ICG fluorescence navigation in LRH supports its broader adoption in liver cancer surgery.

01:21Green Algae
756
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...

01:24Data Reporting and Recording
5.4K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

02:11Reporter Genes
13.1K
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.
