What is a major concern when draining a gangrenous gallbladder?

Draining a gangrenous gallbladder poses a significant concern regarding contamination. This procedure involves handling infected and necrotic tissue, which can release bacteria and other harmful substances into the surrounding environment. If proper aseptic techniques are not meticulously followed, the risk of intra-abdominal infection increases, which can lead to severe complications such as sepsis or peritonitis.

It's essential to maintain strict infection control measures during the drainage procedure to prevent these potential complications. The presence of gangrene indicates that the gallbladder tissue is non-viable, and any manipulation of this tissue without careful consideration of the associated infection risks could result in a widespread contamination of the abdominal cavity. Therefore, the primary concern revolves around ensuring that the surgical field remains free from additional pathogens and that any contaminated materials are managed appropriately to safeguard the patient's overall health.
