Abstract:
Laparoscopic cholecystectomy (LC) is preferred in the treatment of symptomatic cholecystolithiasis. Gallstone spillage is not uncommon, and there have been reports of associated complications. We report a case of a free intraperitoneal gallstone, left inadvertently during LC, which developed an inflammatory phlegmon with abscess containing gallstone, causing extraluminal compression on the distal ileum, resulting in small bowel obstruction. This complication in particular is almost unheard of. The patient underwent laparoscopic drainage of abscess and retrieval of gallstone, which relieved the obstruction. Clinicians, therefore, need to keep an open mind in the workup for bowel obstruction. During LC, gallstone spillage should be prevented and retrieved whenever possible to minimize early and late complications associated with it.

Unusual Results
According to the range rule of thumb, any value above or below two standard deviations, 2σ from the mean, μ is considered unusual.

z Scores and Unusual Values
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...
Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
