① Severe heart, lung, liver, and kidney insufficiency.
②Huge pelvic and abdominal mass: the upper boundary of the mass exceeds the level of the umbilicus or the pregnant uterus is more than 16 gestational weeks, and the volume of uterine fibroids exceeds 4 months of gestation. The pelvic and abdominal cavity have limited operating space, and the mass obstructs the field of vision and establishes a pneumoperitoneum. Or puncture may cause the lump to rupture.
③Abdominal hernia or diaphragmatic hernia: The pressure of the artificial pneumoperitoneum can press the contents of the abdominal cavity into the hernia hole, causing incarceration of the abdominal hernia. The contents of the abdominal cavity enter the thoracic cavity through the diaphragmatic hernia, which can affect the cardiopulmonary function.
④Diffuse peritonitis with intestinal obstruction: Due to the obvious expansion of the intestinal segment, it is easy to cause the danger of intestinal perforation when punctured with a pneumoperitoneum or trocar.
⑤ Inexperienced surgeons.
Severe pelvic adhesions: multiple operations such as bowel surgery, multiple uterine fibroids exfoliation, etc. have caused dense and extensive adhesions around important organs or tissues, such as adhesions of ureters and bowel flexures, which cause important viscera during the separation and adhesion process Damage to organs or tissues.
