Summary
Early gallbladder cancer confined to the mucosa, detected via ultrasound, was successfully treated with laparoscopic cholecystectomy. Endoscopic ultrasonography (EUS) is crucial for precise evaluation before surgery.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Diagnostic Imaging
Background:
- Early detection of gallbladder cancer is crucial for effective treatment.
- Polypoid lesions require detailed examination to rule out malignancy.
- Ultrasound is a common screening tool for gallbladder abnormalities.
Observation:
- A 60-year-old woman presented with a polypoid gallbladder lesion found during a mass survey.
- Endoscopic ultrasonography (EUS) revealed a 10 mm broad-based lesion on the peritoneal surface, without wall invasion.
- Computed tomography (CT) excluded liver invasion or metastasis.
Findings:
- Histological examination confirmed a superficial elevated-type (Type-IIa) papillo-tubular adenocarcinoma, confined to the mucosa.
- The tumor measured 9x8 mm and showed no lymphatic, vascular, or perineural invasion.
- Laparoscopic cholecystectomy was performed, confirming the lesion's resectability.
Implications:
- Laparoscopic cholecystectomy is a viable option for specific early gallbladder cancers (Type-Ip or broad-based ≤10mm on the peritoneal side without wall invasion).
- Precise lesion evaluation using EUS is essential to determine surgical candidacy.
- This case highlights the importance of EUS in guiding treatment strategies for early gallbladder neoplasms.
