Clinical Experience of Interventional Techniques of Electronic Linear Scanning Endoscopic Ultrasonography
Aim:
To summarize the clinical experience of interventional techniques of electronic linear scanning endoscopic ultrasonography (EUS) in the diagnosis and therapy of gastrointestinal disease.
Methods:
Interventional techniques were adopted in 24 cases with Olympus GF-UCT240 echogastroscopy.
EUS-guided fine needle aspiration (EUS-FNA) was performed in 12 cases.
Drainage of pancreatic pseudocyst was carried out in 5 cases.
EUS-guided celiac plexus neurolysis (EUS-CPN) was done in 5 cases.
Intratumoral injection of recombinant human adenovirous p53 in 2 cases.
Results:
Biopsy specimens enough for pathological diagnosis were acquired in 10 of 12 patients by EUS-FNA (83.3%).
All of 12 patients with EUS-FNA, mediastinal tumors in 3 cases, pancreatic tumors in 7 cases, retroperitoneal tumor in 1 case, esophageal tumor in 1 case.
There are no recurrences in 5 patients with drainage of pancreatic pseudosyst over 1 year follow-up survey.
The pain scores were reduced by at least 5 points of visual analog pain scale in 5 cases of advanced pancreatic cancer after EUS-CPN.
All of patients with interventional techniques have no any complications.
Conclusion:
Interventional technique of electronic linear scanning endoscopic ultrasonography is security and efficiency in diagnosis and treatment of gastrointestinal disease.
Case 1
Male, 40 year-old, difficulty in swallowing for 2 months
(A) endoscopy:stenosis in the middle of esophagus,
(B) EUS: mediastinal tumor with low echo, 4.5cm×3.7cm in size, EUS-FNA by 22G needle of puncture,
biopsy result: low-differentiated adenocarcinoma
Case 2
Female, 52 year-old, interval upper abdominal pain for 4 months
CT: tumour in the body of pancreas,.
EUS: tumour 4.3cm×3.7cm in size, asymmetric middle and low echo, EUS-FNA biopsy:cystadenocarcinoma
Case 3
Male, 26 year-old, trauma of abdomen for 5 months
(A) CT: Large pseudocyst in tail of pancreas
(B) EUS: EUS-guided drainage of pancreatic pseudocyst
(C) Place the drainage-tube in stomach
(D) Follow up after 3 months, CT: pancreatic pseudocyst was disappear
