Am J Gastroenterol. Epub 2014 Sep 30. The normal adult gallbladder measures from 7-10 cm in length and 3-4 cm in transverse diameter 6. Imaging modalities used in evaluating gallbladder diseases include ultrasonography, endoscopic ultrasonography, computer tomography, and MRI (26). (2017), 7. The gallbladder neck tapers into the cystic duct. Endoscopic ultrasound guided therapy of benign and malignant biliary obstruction: a case series. The gallbladder communicates with the rest of the biliary system by way of the cystic duct, with bidirectional drainage of bile to and from the common hepatic duct. Traditionally, persistent collections are treated by percutaneous drainage and bile duct decompression. i have had a cholecystectomy and have reacurring pain. PURPOSE: To determine the frequency on magnetic resonance (MR) images of a widened pericholecystic space, which the authors call the expanded gallbladder fossa sign, and to assess the sensitivity and specificity of this sign for cirrhosis. In general, most pathological processes affecting the gallbladder will cause thickening, either due to inflammation or due to precipitation of bile contents due to prolonged stasis. The adult gallbladder holds ~30-50 mL of bile when distended 4-6, although if obstructed can distend to accommodate up to 300 mL 2. 2016 Jul;43(3):421-6. doi: 10.1007/s10396-016-0720-2. Rokitansky-Aschoff sinuses are deep outpouchings or diverticula of the mucosal layer that extend into the outer muscular layer and are variably present 4,6. III. Under endoscopic ultrasound (EUS) control, a 19-gauge needle was inserted through the duodenal wall into the gallbladder fossa fluid collection. Ultrasound and CT are both sensitive to the diagnosis. The main lobar fissure is the functional division of the liver (divides right and left lobes) and is seen in most patients; however, it may be short or absent in some patients. eCollection 2018. 2. 2009 Oct;70(4):786-92. doi: 10.1016/j.gie.2009.04.049.

Laparoscopic cholecystectomy for a left-sided gallbladder. A single center experience in minimally invasive treatment of postcholecystectomy bile leak, complicated with biloma formation. In some cases, the gallbladder "hangs" from the liver from a short mesentery of redundant connective tissue 4. An abdominal ultrasound showed a dilated common bile duct (CBD) with stones inside it. (2006) ISBN:0443100071. J Investig Med High Impact Case Rep. 2020. Ultrasound images of post-cholecystectomy abdomen These are ultrasound images of middle aged female patient who underwent surgical removal of the gall bladder. Evidence of a cholecystectomy is often seen on imaging procedures with surgical clips in the gallbladder fossa and radiologists should be aware of possible complications. 2017 Apr;5(8):190. doi: 10.21037/atm.2017.02.22. Mucus-secreting glands are only present at in the lamina propria layer at the gallbladder neck, and may be joined by enteroendocrine cells 4,6. 0 comment. 2012 Feb 14;18(6):491-7. doi: 10.3748/wjg.v18.i6.491.

Gastrointestinal Physiology 2/E. 9. There are many features to look for as demonstrated in these cases. Piraka C, Shah RJ, Fukami N, Chathadi KV, Chen YK. The gallbladder is located in a shallow fossa along the inferior aspect of the liver, in line with the interlobar fissure that separates right and left liver lobes. 4. Rosai and Ackerman's Surgical Pathology - 2 Volume Set. EUS-guided transesophageal, transgastric, and transcolonic drainage of intra-abdominal fluid collections and abscesses. Gray's Anatomy. Fig. Evaluation consists of longitudinal (sagittal and parasagittal) and transverse images of all aspects of the liver (right side, midline, and left side of the liver). Acalculous cholecystitis presenting in an out-patient with no risk factors Ultrasonography (US) is the method of choice for detection of gallstones. Unable to process the form. (2010) ISBN:140518275X. The Gallbladder Fossa on the Undersurface of the Gallbladder The gallbladder fossa is a long and relatively narrow bed within which the gallbladder lies. ACG Case Rep J. 11: Ultrasound image showing abscess in the gallbladder fossa (red wheel). It consists of loose connective tissue and vessels that anchor and connect the gallbladder to the liver. Endoscopic Ultrasound-Guided Creation of a Gastrogastric Conduit After Pancreaticoduodenectomy in a Patient with Prior Roux-en-Y Gastric Bypass. Nayak SB, Aithal AP, Padavinangadi A, Prabhu G. Double pouched, sigmoid gallbladder that can cause a diagnostic dilemma to radiologists: a case report. Gray H. Anatomy of the Human Body, 20th edition. J Med Ultrason (2001). Endoprosthesis insertion was successful in both cases, resulting in rapid symptomatic and radiographic improvement. Jamieson GG. Collections of fluid in the gallbladder fossa can be detected by ultrasound in as many as 29% of patients following cholecystectomy. The gallbladder concentrates bile using mechanism of active transport of sodium and chloride, effectively removing water and slightly increasing acidity of bile. Electrocautery is used to dissect the gallbladder free from the liver. World J Gastroenterol. Endoscopic ultrasound-guided biliary drainage. Greenfield LJ, Mulholland MW. Gallbladder carcinoma may appear at any of these imaging modalities as (Fig.1): 1. For descriptive purposes, it may be divided into the following segments 6: The gallbladder is closely apposed to the liver within the fossa. Gallbladder carcinoma can appear as a mass in the gallbladder fossa with obliteration of the gallbladder (the most common finding), can present as focal or diffuse irregular gallbladder wall thickening, or can appear as an intraluminal polypoid gallbladder mass (typically >1 cm in size with prominent internal vascularity). Ultrasound or CT scan An ultrasound gives an image of your gallbladder and nearby structures. The outer muscular layer forms the framework of the gallbladder and consists of dense fibrous tissue interlaced with randomly-oriented smooth muscle fibers, contrasting with the well-organized longitudinal and circular organization within the intestine 4,6. This area is replaced by dense fibrous tissue, seen as a linear echogenic lesion (arrowed). Mass occupying or replacing lumen (40-60%) The fundus commonly projects inferior to the right liver margin. World J. Gastroenterol. Das R, Zeh H, Zureikat A, Slivka A, Papachristou GI. 2 doctors agree. There is no single cystic vein, but rather the gallbladder drains directly into the venous system of the liver through the gallbladder fossa (cystic veins) and by a number of veins into the right branch of the portal vein 2. It functions to accumulate and concentrate bile between meals. An intraoperative ultrasound showing a close association of the middle hepatic vein and gallbladder fossa is shown in Figure 3. Three distinct pathways have been described based on cadaveric dissection 8: These are thought to converge at aortocaval and para-aortic nodes near the renal veins 8. Susan Standring. The gallbladder fossa was considered expanded if there was an enlargement of the pericholecystic space, and the space was bounded laterally by the edge of the right hepatic lobe, The gallbladder is a pear-shaped musculomembranous sac located along the undersurface of the liver. Churchill Livingstone.

It shows increased echogenicity and coarsened echotexture. 15: Abdominal radiogram showing (a)) partial layer of mineralisation outlining the gallbladder wall. Most frequent aberrant locations in descending order are beneath left lobe of liver, intraheptic, retrohepatic, within the falciform ligament, within the interlobar fissure, suprahepatic, and within the anterior abdominal wall. Collections of fluid in the gallbladder fossa can be detected by ultrasound in as many as 29% of patients following cholecystectomy. No issue: The gallbladder fossa is simply an anatomic description of the location of the gallbladder on the liver. The normal gallbladder by ultrasound is usually more elongated and its shape is closer to a zucchini than a pear. There are extensive capillaries and small venules, but absent lymphatics 4. 2014 Sep;47(5):432-9. doi: 10.5946/ce.2014.47.5.432.
