alright, my mistake...it's clearly not cholelithiasis.
here's some information that I pull up from a site, I saved you the hassel of hunting for it while scrolling through the page.

GALLBLADDER DISEASE WITHOUT STONES (ACALCULOUS GALLBLADDER DISEASE)
Gallbladder disease can occur without stones, a condition called acalculous gallbladder disease. It can be acute (arising suddenly, often as a one-time occurrence) or chronic (persistent):
Acute acalculous gallbladder disease usually occurs in patients who are very ill from other disorders. In such cases, inflammation occurs in the gallbladder, usually from a diminished blood supply or an impairment in the ability of the gallbladder to contract.
Chronic acalculous gallbladder disease (also called biliary dyskinesia) appears to be caused by muscle defects or other problems in the gallbladder that impair its ability to contract and release bile.
Diagnosing Acalculous Gallbladder Disease
Diagnosing Acute Acalculous Gallbladder Disease. Symptoms are similar to acute cholecystitis with gallstones, but they may be obscured by other medical conditions, since patients with this condition are often critically ill with other illnesses.
Diagnosing Chronic Acalculous Gallbladder Disease. Chronic acalculous gallbladder disease is usually diagnosed when a patient complains of gallbladder symptoms but there is no evidence of stones using standard imaging techniques. (More than half of patients initially diagnosed with this disease, however, are eventually shown to have small stones or gallbladder sludge.) The patient is given the hormone cholecystokinin octapeptide (CCK), which induces gallbladder contraction, followed by a radioisotope scan that determines if the gallbladder is emptying correctly. If the gallbladder demonstrates difficulty releasing bile, doctors usually consider the diagnosis confirmed.
Treatment for Acalculous Gallbladder Disease
Treatment for Acute Acalculous Gallbladder Disease. Acute acalculous gallbladder disease has a very high rate of serious complications (gangrene, perforation, and pus in the gallbladder), so emergency removal of the gallbladder is warranted.
Treatment for Chronic Acalculous Gallbladder Disease. Most patients (75% to 90%) diagnosed with chronic acalculous gallbladder disease are relieved of their symptoms by cholecystectomy (removal of the gallbladder). [See What Are the Surgical Procedures for Gallstones and Gallbladder Disease?]
I hope this helps a bit.
