HI Thank for asking to HCM The small intestine resection surgery done, but for what resection done, you have not stated it here, without knowing this it is difficult to say anything on medical ground, we always looking for at least brief medical and surgical history, so we can provisionally advise you something, more over in a surgical cases only the surgeon knows the exact intraoperative procedure, the anastomosis done by him the method he applied, these all factor are greatly responsible for post surgical events, so you better discus it with the surgeon who did the surgery, have nice day .
