Whether patients can smoke after minimally invasive surgery should be objectively analyzed according to the specific surgical method of the patient and different factors of postoperative recovery.1. If patients undergo minimally invasive laparoscopic appendectomy due to acute suppurative appendicitis, the abdominal inflammation is absorbed more quickly after the surgery, the incision heals well, and gastrointestinal function recovers more quickly. At this time, the patient a small amount of smoking does not cause serious impact on the condition. However, it is not recommended to smoke too much, so as not to cause lung infection.2. If patients undergo minimally invasive laparoscopic surgery for malignant tumors, such as gastric malignant tumors, liver malignant tumors, after the surgery, patients will often be accompanied by varying degrees of peritoneal fluid, gastrointestinal peristalsis, lung infection and other related complications. If the patient smokes, it will aggravate the condition, which is not conducive to faster recovery, so it is not recommended that the patient smoke after surgery.
