In our outpatient clinic, we often come across patients who ask if minimally invasive surgery can be performed to treat inguinal hernias. After receiving our affirmative answer, they will immediately ask for further clarification: “Does minimally invasive surgery mean that a single injection will be enough?” At this point, our doctors often have to go to great lengths to explain to him that truly minimally invasive surgery is not just a shot, but that laparoscopic hernia repair is the minimally invasive surgery that cures inguinal hernias. We have talked about laparoscopy more thoroughly in many of our previous articles. Today, we mainly focus on the harmful injection method (the so-called “a needle spirit”), to pick up its true colors. Inguinal hernia injection therapy, commonly known as “a needle spirit”, in the 30s and 40s in Europe and the United States was popular for a while. The theory is that the hardener or adhesive (such as glycerol carbolic acid, sodium cod liver oil, compound quinine, medical glue, etc.), injected into the hernia ring mouth and inguinal canal. After injection into the body, the sclerosing agent will undergo a biochemical reaction and harden rapidly like cement, thus bonding the local muscles and fascia together to block the hernia contents from protruding, thus playing a therapeutic role. But soon, medical experts found its various shortcomings: 1, injection treatment has a great blindness. Whether operated with bare hands or under ultrasound guidance, it is difficult to accurately localize. Therefore, the recurrence rate after injection is as high as more than 50%; 2, injection often leads to damage or adhesion of spermatic cord blood vessels and vas deferens, affecting fertility, and in serious cases, even ischemic orchitis leading to testicular atrophy, which is self-evident to men with fertility requirements; 3, if sclerosing agent injection mistakenly enters into the abdominal cavity and intestinal cavity, it may lead to intestinal adhesion, intestinal obstruction, intestinal necrosis and other serious complications, or mistakenly enters into femoral blood vessels to cause Lower extremity vascular embolism, these complications are serious and even endanger the patient’s life; 4, after the failure of injection therapy, when surgery is needed, due to the complete change of local anatomical structure, the tissues are hard as cement, which will lead to intraoperative anatomical difficulties, more bleeding, and the chances of postoperative pain, hematoma, and infection will be greatly increased; Due to the above reasons, injection therapy was completely banned in the 1960s and 1970s in foreign countries. But in recent years in China, this treatment method has made a comeback under the banner of minimally invasive. In fact, careful readers can easily find that those who carry out this treatment are often some informal medical institutions or small private clinics. They take advantage of some patients’ fear of surgery and their greed for a cheaper alternative. In fact, now the hernia repair surgery in the technology has been very mature, whether laparoscopic or open surgery are safe and fast, usually one or two days after the operation can be discharged from the hospital, the impact on daily work and life is very small. Here we call on the majority of patients and friends, in the choice of medical institutions and treatment options, must be vigilant, keep your eyes peeled, do not lose because of small.
