Cholecystitis or a quinolone antibiotic (such as ciprofloxacin) and anaerobic bacteria coverage, such as metronidazole. For penicillin allergic people, aztreonam or a quinolone with metronidazole may be used. In cases of severe inflammation, shock, or if the person has higher risk for general anesthesia (required for cholecystectomy), an interventional radiologist may insert a percutaneous drainage catheter into the gallbladder ('percutaneous cholecystostomy tube') and treat the person with antibiotics until the acute inflammation resolves. A cholecystectomy may then be warranted if the person's condition improves. Homeopathic approaches to treating cholecystitis have not been validated by evidence and should not be used in
Body of water example, most reservoirs are created by engineering dams, but some natural lakes are used as reservoirs. Similarly, most harbors are naturally occurring bays, but some harbors have been created through construction. Bodies of water that are navigable are known as waterways. Some bodies of water collect and move water, such as rivers and streams, and others primarily hold water, such as lakes and oceans. The term "body of water" can also refer to a reservoir of water held by a plant, technically known as a phytotelma. Bodies of water are affected by gravity which is what creates the tidal effects
