A young man from Shantou, Guangdong, with congenital megacolon, has been suffering from difficulty in defecation since birth, with abdominal distension, abdominal pain, dizziness, palpitations, and laxatives and enemas as a daily routine. In recent years, he has been suffering more and more from the difficulty of having a bowel movement, sometimes taking 2-3 weeks to have a bowel movement. At that time, he heard that the disease would naturally get better when he grew up, but now his condition was getting worse. At the local hospital, it was found that Adong’s large intestine was 13 cm wide and more than 1.5 meters long, making it inoperable locally. After moving around several hospitals, Adong came to Sun Yat Sen Memorial Hospital of Sun Yat Sen University in Guangzhou. Doctors only made four small holes in his abdomen and cut a small incision of less than 5 cm, and cured his persistent disease that had plagued him for more than 20 years. After a thorough examination and careful preparation, Professor Chen Shuang, Director of Gastrointestinal Surgery at Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University, received Adong and decided to perform a laparoscopic resection of his giant colon, followed by anastomosis of the small intestine to the rectum. Two days after the operation, Adong was able to get out of bed and was discharged from the hospital in a week. According to Prof. Chen Shuang, most adults with megacolon disease like Adon are of the short-stem type. Because the ganglion cells of the intestinal wall do not develop in the near anorectal part of the intestine, making this part of the intestine can not expand and peristaltic, so that the colon above this section of the intestine is passively expanded to become megacolon, the root of the disease is in the intestinal tube below the megacolon. Professor Chen said that congenital megacolon is a more common congenital disease, mainly manifested as difficult defecation and abdominal distension after birth. Patients with the short-dry type can have their symptoms relieved by enemas, but they often do not heal on their own. Children before the age of half a year are not suitable for surgery and can be treated by enema; after more than 6 months, they can be treated surgically. Nowadays, it is possible to remove the “narrow” intestine through the anus, and good results can be achieved without opening the abdomen.
