Recently, our department admitted a patient with a huge and complex incisional hernia after colostomy. The patient was a female, 76 years old, whose abdominal wall defect reached a maximum diameter of 30 cm, and two other defects were also at 5 cm, with the abdomen obviously bulging out, and a second abdominal cavity had been formed. The patient had episodes of abdominal pain, which significantly affected her daily life. He had been to all the major hospitals in the city and underwent surgical repair, but he was not cured. The patient came to our department for surgical treatment. We analyzed: abdominal wall incisional hernia is a common complication after abdominal surgery, and its incidence reaches 2%~11%. The incidence of incisional hernia is 2%~11%. It is related to incisional infection, postoperative intra-abdominal pressure, surgical technique, type of incision, and nutritional status of the patient. Incisional hernia can not be self-healing, all need surgery to repair. According to the hernia and abdominal wall surgery group of the Chinese Surgical Association of the classification of incisional hernia of the abdominal wall, the diameter of the hernia ring ≥ 10cm for a huge incisional hernia, is a high recurrence rate, very difficult to deal with the surgical disease, the disease occurs more often in the complex or elderly patients after abdominal surgery, due to the age of the patient, the abdominal wall subcutaneous fat is thicker, the abdominal muscles and fibrous tissue is weak, incisional hernia is prone to rapid expansion, so that the patient movement is limited, and the patient can not move, and the patient can not move. The incisional hernia is easy to expand rapidly after the incisional hernia occurs, so that the patient’s movement is limited, or even suddenly incarcerated, rupture and endanger the patient’s life. In addition, due to a large number of abdominal organs prolonged prolapse in the hernia sac outside the abdominal cavity to form a second abdominal cavity, resulting in the abdominal cavity capacity gradually become smaller, this kind of patients are often combined with constipation, chronic respiratory diseases (such as emphysema, chronic asthmatic bronchitis) and hypertension and other diseases, and thus less tolerant to the operation and the failure rate and high. There are two key issues that must be addressed in the treatment of this type of incisional hernia: one is the retraction of the many visceral tissues that have been dislodged into the extra-abdominal hernia sac, and the other is the repair of the large defect in the abdominal wall. Due to the prolonged prolapse of intra-abdominal intestinal tubes and omental tissues into the extra-abdominal hernia sac, the capacity of the original abdominal cavity is significantly reduced, and if the contents of the hernia sac are retracted into the abdominal cavity and the defect is forcibly sutured, it will inevitably result in a short period of sharp rise in abdominal pressure, resulting in the formation of the abdominal septal compartment syndrome, which will lead to the patient’s respiratory and circulatory failure, and this will bring about serious consequences in the clinical field. Because of the large abdominal wall defect, forced closure of the hernia ring will result in recurrence or new defects, which need to be repaired by filling with a specific piece of material. Currently, the latest concepts and norms are: (1) to guarantee tension-free: therefore, the patch should be large enough and required to exceed the hernia edge by 3-5 cm; (2) to prevent the occurrence of enterocutaneous fistulae: applying anti-adhesion composite materials, the abdominal side of which is expanded polytetrafluoroethylene, to prevent intestinal adhesions and enterocutaneous fistulae. The other side of the polypropylene material, in good tissue compatibility, easy to heal. (3) Skillful surgical operation and short time; (4) Avoiding the use of silk threads: silk threads are poor in anti-infection and prone to suture reaction, which can cause surgical failure. Therefore, for this patient, the abdominal wall defect is huge and rare, the conventional surgical method can not be solved at all, the specific composite patch must be used to perform a huge complex incisional hernia tension-free patch repair, and it must be performed according to the specifications. After adequate preoperative preparation, the patient successfully underwent tension-free patch repair of huge complex incisional hernia of the abdominal wall, and the patient’s wound healed well and was successfully repaired. The success of this operation signifies that the level of abdominal wall and hernia treatment in our hospital has reached the leading level in China, which is also the first case in Tianjin. The successful implementation of this operation also proved that the combined Chinese and Western medicine surgery department of our hospital is in the leading position in the field of hernia surgery in Tianjin.
