[/INST] Hi. This is a par of the sequel after any surgery with septic peritonitis, whether due to perforated appendix or any part of the intestine. After the perforation the intestinal contents spread in the peritoneal cavity. The intestinal (appendix is a part of intestine) contents contain bad bacteria and once they reach the peritoneum, infection becomes widespread. Sometimes even the best antibiotics may take time to control the infection. The white foul smelling discharge is pus from peritonitis. This is coming from the peritoneal cavity. The bad odor is produced by the breakdown of the tissue by the bacteria as a byproduct of the process of pus formation. Pus culture and sensitivity guides for the best antibiotics which may help fasten the process of controlling infection. Blood proteins should be within normal limits for a good healing. Hemoglobin should be good. There must not be any affection of liver / kidneys. May need sonography or CT to decide what is the extent of infection inside abdomen before your Surgeon may decide to re-open the abdomen, if he feels necessary. </s>
