Hepatectomy is often a larger procedure and patients tend to have a longer recovery time after surgery; in my observation, even a young person with no major preoperative physical problems usually takes 3 months – 6 months before his or her strength returns to preoperative levels. Since hepatectomy is discharged from the hospital after about 1 week, nutritional support during this period after discharge from the hospital depends entirely on dietary sources, therefore, proper dietary formula plays a very critical role during this period. We know that glucose – fat – protein are the three major nutrients for the human body, sugar and fat are relatively single sources and can be fully satisfied in a normal diet, except for protein, which is composed of more than 20 amino acids, and the importance of different amino acids to the human body varies, and the amino acid profile of different foods varies greatly, therefore, the only way to replenish liver resection patients after surgery is to consume more high-quality protein Adequate amounts of the essential amino acids that build the body play a key role in the nutritional support after hepatectomy. There are also more sources of high quality protein, and not the more expensive and rare food is better. I personally believe that animal protein contained in foods such as fish (especially sea fish), lean meat, eggs, and cow’s milk is a good source of high quality protein. Cooking methods can be based on personal preference. Fish is mainly steamed, for lean meat I recommend the steamer stew broth, because the steamer cooking process first produced distilled water, and then the formation of broth, this process not only filtered the harmful impurities in the tap water, and a long time low fire stew also makes the lean meat in the protein more fully hydrolyzed into peptides and amino acids dissolved in the broth, delicious, nutrients are very easy to be absorbed by the body. In addition, an egg weighs about 50 grams and contains 7 grams of protein (a bottle of human albumin injection priced at 400 yuan is only 10 g of protein), 6 grams of fat and 82 kcal of calories, with cholesterol and lecithin mainly found in the yolk. Egg protein is also high-quality protein, with an excellent amino acid profile and a utilization rate of more than 98%. 1-2 cooked eggs per day is an affordable nutritional product for recovery from liver and gallbladder surgery, but, of course, too much cholesterol can be detrimental to health, so patients with high blood cholesterol can eat less egg yolk to reduce cholesterol intake.
