### output:

Hi ! From the history you have mentioned, it could be just that starting of oral food was early, and so there is persisting paralytic illus due to which the present problems arose. It may get relieved of its own by conservative management. One perplexing finding is of loose stool post sportively, which usually occurs due to any kind of peritoneal irritation to the colon. I am not sure, but there could be some fluid accumulation due to very many causes resulting in peritonitis which caused the secondary bowel obstruction. The vomiting of bilious fluid points to obstruction of the intestines. The treating surgeon is the best judge, and he may go for some investigations like complete blood count, ultrasound abdomen, X-ray abdomen in erect posture to exclude pathological processes in the abdomen. If diagnosed as a mechanical obstruction, he may be in need for a relook surgery in the hospital. I wish him an early recovery.
