Diseases related to the spleen include certain hematopoietic disorders, infectious diseases, congestive splenomegaly, splenic trauma, splenic space-occupying lesions and malformed vascular lesions. Long-term clinical practice has shown that the effective treatment for these diseases is splenectomy. Traditional open splenectomy involves long abdominal incision, long hospitalization time and many postoperative complications. Since the first case of laparoscopic splenectomy in adults was firstly accomplished abroad in 1991, this technique has also been carried out in China one after another. Clinical data show that laparoscopic splenectomy is safe and feasible, with the advantages of small surgical trauma, mild postoperative pain, less interference with physiological functions, fast postoperative recovery, short hospitalization time and beautiful wounds. Currently, laparoscopic splenectomy has become one of the most common laparoscopic parenchymal organ surgeries in abdominal surgery. Advantages of laparoscopic splenectomy 1. Laparoscopy is a truly minimally invasive treatment method with minimal trauma. 2. Poking holes in the abdominal wall instead of open surgery avoids damage to the abdominal wall muscles, blood vessels and corresponding nerves, and there will be no abdominal wall weakness and abdominal wall incisional hernia after the operation, no scarring of the abdominal wall muscles affecting the motor function, no numbness of the corresponding skin caused by severing of the abdominal wall nerves, and avoiding the intra-abdominal adhesion. 3. Four holes are poked in the abdomen, eliminating the psychological fear of abdominal incision scarring, which is especially welcomed by female patients. 4. Laparoscopic surgery has little disturbance to the organs in the abdominal cavity, hemostasis is complete during the operation, bleeding is minimal, and rinsing is thorough before the end of the operation to keep the abdominal cavity clean. As a result, the postoperative intestinal function recovers quickly, can eat earlier, and greatly reduces the factors of postoperative intestinal adhesion. 5. Early getting out of bed after operation, unlimited sleeping posture, turning over at will, greatly reducing the intensity of accompanying family care. 6. Fast postoperative recovery, significantly reduced complications, thus greatly reducing hospitalization costs. Indications for laparoscopic splenectomy 1, hematologic diseases related to hypersplenism, including idiopathic thrombocytopenic purpura, hereditary spherocytosis, thalassemia, hemolytic anemia, chronic granulocytic leukemia, lymphoma, and myelodysplastic syndromes, etc. Benign splenic tumors, including splenic cysts, splenic hemangiomas. 3.Vital signs of patients with traumatic splenic rupture are stable and the estimated bleeding volume is not big. 4.Liver cirrhosis with mild portal hypertension, without obvious esophagogastric fundus varices, combined with hypersplenism. 5.Infectious splenic diseases such as splenic abscess, splenic tuberculosis, etc., estimated that the abdominal inflammation is not heavy and the adhesion is mild. 6.Other splenic diseases such as wandering spleen.
