Summary
Routine port site excision (PSE) during completion extended cholecystectomy (CEC) for incidental gallbladder cancer (iGBC) is not essential. Studies show PSE does not significantly improve survival or reduce recurrence rates in iGBC patients.
Area of Science:
- Surgical Oncology
- Gastroenterology
Background:
- Completion extended cholecystectomy (CEC) is standard for incidental gallbladder cancer (iGBC).
- The role of laparoscopic port site excision (PSE) during CEC for iGBC is debated.
- This review assesses the necessity of routine PSE in iGBC management.
Purpose of the Study:
- To evaluate the clinical benefit of routine port site excision (PSE) in patients undergoing completion extended cholecystectomy (CEC) for incidental gallbladder cancer (iGBC).
Main Methods:
- A systematic literature search was performed across major databases (PubMed, Google Scholar, Scopus, Cochrane Library).
- Keywords included "incidental gallbladder carcinoma," "radical cholecystectomy," "extended cholecystectomy," "port site excision," "port site recurrence," and "port site metastasis."
- Analysis focused on outcomes comparing PSE and non-PSE groups in iGBC patients.
Main Results:
- Three studies with 503 iGBC patients were analyzed.
- Malignant port site involvement occurred in 8.2% of patients who had PSE.
- Recurrence rates (36% vs. 40%) and overall survival (36-89 vs. 30-45 months) were not significantly different between PSE and non-PSE groups.
Conclusions:
- Routine port site excision (PSE) during completion extended cholecystectomy (CEC) for incidental gallbladder cancer (iGBC) is not demonstrably necessary.
- PSE does not significantly decrease distant recurrence or enhance overall survival in iGBC management.
