Mr. Zhang, 52 years old, had recurrent right upper abdominal pain for more than 1 year, and was admitted to our laparoscopic surgery department in May 2009 for “acute attack of gallbladder stone and chronic cholecystitis”. 3 years ago, he also suffered from inguinal hernia (commonly known as hernia), and recently a goose egg-sized lump often appeared in his right groin, which has affected his daily life. Mr. Zhang and his family asked if minimally invasive treatment could be adopted and cure both diseases at once. As a rule, in order to reduce the risk of surgery, doctors generally have to operate on such patients in two operations, such as traditional open surgery, which usually requires two 5-10 cm surgical incisions in the upper and lower abdomen, respectively. After meticulous preoperative evaluation and careful preparation, we developed the best surgical plan: after general anesthesia, four 0.5-1.0 cm poke holes were made in the abdomen, then laparoscopic inguinal hernia repair and laparoscopic cholecystectomy were completed, and the patient ate the next day and was discharged 4 days after surgery with no discomfort at 8 months of follow-up. A procedure such as Mr. Zhang’s, in which two or more abdominal lesions of different organs are treated simultaneously in the same laparoscopic operation, is called combined laparoscopic surgery. I. What are the advantages of combined laparoscopic surgery? 1, with the advantages of general laparoscopic conventional surgery: less trauma, less bleeding, faster recovery, fewer complications, shorter hospital stay, and beautiful abdomen. 2, two birds with one stone (multi-bird): treating two or more diseases through one operation, reducing the need for extended incisions and multiple incisions in traditional surgery, fully reflecting the advantages of minimally invasive; avoiding patients’ second admission and second operations, which not only reduces patients’ pain, but also reduces treatment costs, with the incomparable advantages of traditional surgery. 3, to achieve joint surgery of different disciplines: in the past, patients with abdominal surgical diseases, gynecological diseases and urological diseases were mostly operated in separate departments and sub-operations. Laparoscopy can treat and diagnose interdisciplinary diseases at the same time because of clear vision, slender instruments and flexible operation. Second, which diseases are suitable for combined laparoscopic surgery? 1.Two or more abdominal surgical diseases at the same time: gallbladder stones (polyps), bile duct stones, appendicitis, inguinal hernia, intestinal adhesions, liver cysts, hepatic hemangioma, spleen cysts, pancreatic cysts, benign tumors of the gastrointestinal tract, early to mid-stage gastric cancer and colorectal cancer, etc. 2.Abdominal surgical diseases combined with gynecological diseases or urological diseases: ovarian cysts, teratoma, uterine fibroids, renal cysts, ureteral calculi, etc. 3, abdominal surgical diseases with severe diabetes: 8 months ago, the director of our department, Jiang Feizhao, completed the world’s first laparoscopic partial colectomy combined with duodenojejunal bypass, which not only cured the colon disease, but also made the patient completely free from the long-term use of insulin; recently, he also completed laparoscopic cholecystectomy combined with duodenojejunal bypass, which cured the gallbladder stones and relieved diabetes.
