“…However, it is mostly used in the extrahepatic bile duct and pancreatic duct and so reported cases of the use of IDUS of the gallbladder are few and its usefulness is therefore unknown. IDUS of the gallbladder in applications of the ENGBD technique is being attempted; 4,5 however, the number of cases are still few. Although insertion of the miniature probe into the gallbladder is difficult, when the guidewire was successfully placed into the gallbladder, it was possible to insert the miniature probe into gallbladder at a very high rate (96.4%).…”

“…As an endoscopic transpapillary approach for the gallbladder, Kozarek 1 first performed a selective cannulation towards a cystic duct in 1984. Thereafter, endoscopic retrograde catheterization of the gallbladder (ERCG), 2 and endoscopic transpapillary catheterization in the gallbladder (ETCG) 3 have been performed, and IDUS is also being tested for the gallbladder using this ETCG technique 4–6 . However, these endoscopic transpapillary approaches for the gallbladder and IDUS of the gallbladder have not been investigated using a large number of patients.…”

Background: Although endoscopic naso-gallbladder drainage (ENGBD) for gallbladder disease is useful, the procedure is difficult and investigations involving many cases are lacking. Furthermore, reports on transpapillary intraductal ultrasonography (IDUS) of the gallbladder using a miniature probe are rare. Methods: A total of 150 patients (119 suspected of having gallbladder carcinoma, 24 with acute cholecystitis (AC), and seven with Mirizzi's syndrome (MS)) were the subject. (i) ENGBD: We attempted to put ENGBD tube into the GB. (ii) IDUS of the gallbladder: Using the previous ENGBD tube, we attempted to insert the miniature probe into the gallbladder and perform transpapillary IDUS of the gallbladder. In five patients, we attempted three-dimensional intraductal ultrasonography (3D-IDUS). Results: (i) ENGBD: Overall success rate was 74.7% (112/150); the rate for the patients suspected of having gallbladder carcinoma was 75.6% (90/119), and was 71.0% (22/31) for the AC and MS patients. Inflammation and jaundice improved in 20/22 successful patients with AC and MS. Success rate was higher when cystic duct branching was from the lower and middle parts of the common bile duct than from the upper part, and was higher when branching was upwards than downwards. (ii) IDUS of the gallbladder: Success rate for miniature probe insertion into the gallbladder was 96.4% (54/ 56). Lesions could be visualized in 50/54 patients (92.6%). Of these, detailed evaluation of the locus could be performed in 41. In five patients attempted 3D-IDUS, the relationship between the lesion and its location was readily grasped. Conclusion: IDUS of the gallbladder is superior for diagnosing minute images. Improvement on the device will further increase its usefulness.Key words: endoscopic naso-gallbladder drainage (ENGBD), endoscopic transpapillary catheterization to gallbladder (GB), intraductal ultrasonography (IDUS) of GB, three-dimensional IDUS.

“…Ultrasonic microprobes to be applied during endoscopy have been developed for ultrasonic diagnosis of gastrointestinal tract diseases, and this technique was also applied through a transpapillary route in pancreatobiliary diseases 15 . Intra‐gallbladder sonography using the technique of ETCG was reported 10 . The ultrasonic microprobe (MP‐PN20–06L; Aloka Co., Tokyo, Japan) used has a length of 1900 mm long, a diameter of 2 mm and a tip containing a 20 MHz radial scan transducer.…”

It is often difficult to determine the precise nature of lesions in the gallbladder by radiographic, endoscopic and ultrasonographic methods. The approach to the gallbladder by a percutaneous transhepatic route has been reported. However, there is a possibility of seeding tumor cells into the peritoneal cavity and liver in a percutaneous procedure. On the contrary, transpapillary route can be performed without a possibility of seeding. The double‐contrast cholecystography, intragallbladder sonography, direct biopsy of gallbladder lesions and cytology using gallbladder bile have been performed by the procedure of the transpapillary catheterization into the gallbladder. Confirming malignancy by histopathological diagnosis is desirous for determining therapeutic strategy in gallbladder carcinoma. Gathering gallbladder bile is comparatively easier than biopsy of the lesion using the transpapillary catheterization into the gallbladder. Examination of telomerase‐related molecules is useful for diagnosis of pancreatic carcinoma. Usefulness of combination assay of human telomerase reverse transcriptase mRNA (hTERT mRNA) and cytology using gallbladder bile obtained by transpapillary catheterization is reported here. However, it would appear that hTERT mRNA is less important in the diagnosis of gallbladder carcinoma than in that of pancreatic carcinoma. When the molecular biological substances with higher sensitivity are found, the reliance of the combination assay of the molecular biological substances and cytology will be established.

Endoscopic ultrasonography (EUS) is nowadays a clinically relevant technology and its findings can have a major impact on patient management. This technique is currently indicated for staging digestive cancers, assessment of submucosal tumors, diagnosis of intestinal wall infiltrative diseases, common bile-duct stones and gut neuroendocrine tumors. As far as neoplasms are concerned, EUS appears to be a reliable and safe technique, thus making the physician able to plan either an aggressive surgical treatment, or a conservative palliative therapy. This is of the utmost importance in order to optimize medical-related costs, and to make the best therapeutic decision for each individual patient. EUS is also helpful in monitoring the course of a disease, as it is simple and virtually without complications. When EUS findings are not sufficient for a complete diagnosis, it is now possible to perform an EUS-guided fine-needle biopsy, which can allow a cytological diagnosis. Finally, some therapeutic endosonography-guided procedures are being increasingly adopted, such as cystoenterostomy, celiac plexus neurolysis, cholangio-pancreatography and selective injection of botulinum toxin in the muscle layer of the lower esophageal sphincter.
