Inguinal hernia is a common disease in general surgery, and the mainstream surgical concept of repairing the pubic foramen area has become an important area for inguinal hernia repair. Conventional inguinal hernia patch repair and laparoscopic transperitoneal anterior hernia patch repair (TAPP) have become the mainstream surgical approaches. Minimally invasive surgery has a large proportion of TAPP procedures for inguinal hernia treatment due to the advantages of relatively fast clinical recovery and the possibility of abdominal exploration. Surgeons need basic surgical steps and related knowledge to master this procedure and patient communication, and this article provides knowledge related to TAPP for inguinal hernia in combination with related knowledge and beautiful illustrations by Professor Tang Rui. For every surgery and patient communication, it is always necessary to communicate with hand-drawn pictures or play videos, which is troublesome, and now summarize the simple process to facilitate communication. Indications: Adult inguinal hernia of all types, especially bilateral hernia and patients with recurrence after open surgery. Brief surgical procedure: Position: mostly in the flat position or with the head low and feet high at 15 degrees. Puncture hole: Mostly 1 cm below the umbilicus and 5 mm puncture holes are placed at the outer edge of the rectus abdominis muscle to the left and right of the flat umbilicus. After probing the abdominal cavity for no abnormalities, the preperitoneal tissues were observed for anatomical positioning of the tissue. Identify inguinal hernias as straight, hiatal, and femoral hernias, etc. This figure illustrates a hiatal hernia, which is located lateral to the inferior abdominal wall vessels. The peritoneum is opened 6-8 cm above the internal inguinal hernia orifice, not exceeding the medial umbilical fold to avoid injury to the bladder. The peritoneum is separated medial to the subabdominal vessels to expose the retropubic space. Care is taken to expose the pubic comb ligament, the pubic symphysis and coronary vessels of death, and the retropubic vascular plexus. The hernia sac is separated, the spermatic cord and spermatic vessels are exposed, and the ventralized spermatic cord is debulked for 5-6 cm. The anterolateral Bogros hiatus is also separated. The femoral ring, straight hernia triangle, hiatal hernia triangle, crown of death, danger triangle, and pain triangle are identified. After separating the peritoneal tissue above the opening of the internal ring, a suitable hernia patch is placed in this gap. The peritoneum is closed to avoid adhesions of the hernia patch to erode the intestinal canal due to peritoneal exposure. Of course, this procedure is still limited in cases of extensive abdominal adhesions and abdominal wall infection. Combined with the beautiful illustrations (, you can basically have a certain understanding of this surgical procedure, which can allow the surgeon to be familiar with the anatomy again, and also communicate with the patient to reduce the process of handwriting and drawing, which is very convenient ah.
