In the past 20 years, we have used elimination of hemorrhoid spirit rectal and internal and external injection, endorectal scar fixation based on the addition of anal canal tightening treatment of complete rectal prolapse, and achieved better results, is reported below. I. Data and methods 1. General data: Of the 67 patients in this group, 16 were men and 51 were women, aged 12 to 18 years; medical history ranged from 3 to 63 y; the number of births in female patients ranged from 2 to 12, including 33 cases with more than 5 births. According to the criteria set by the National Anal Conference in 1975, all 67 patients had Ⅲ° rectal prolapse. The length of prolapse ranged from 10 to 17 cm. All cases had different degrees of anal flaccidity and weak contraction. Among them, 64 cases had two fingers (100 px in diameter) and 3 cases had three fingers (150 px in diameter) of anal flaccidity in the natural state; all had mucosal ectasia on anal examination. Anal rectal manometry indicated that the anal sphincter function was severely decreased in all cases. During the course of the disease, 3 cases were treated by eversion folding, and 13 cases were treated by simple injection therapy. 2.Surgical method: After the completion of lumbar anesthesia, take a truncated position, routinely disinfect the skin and anal canal and rectum, lay a sterile towel, and perform the surgery in 3 steps: ① Rectal submucosal injection and suture method: ask the patient to make the rectum prolapse by force, or pull out the rectum completely from the anus with a mouse tooth clamp, use a 5ml syringe to draw 0.5% procaine mixed with anti-hemorrhoid liquid to form a 1:1 liquid, attach a No. 7 intracardiac injection needle at 3 The rectal submucosal bi-directional column injection was carried out at 3, 6, 9 and 12 o’clock orientation, with 5~8ml of drug injected in each column, and point supplemental injection was given between each column according to the situation. After injection, the rectal mucosa was clamped longitudinally at 3, 9 and 12 points with a longitudinal clamp of 8~250px at the distal end of the prolapsed rectum, and 3~5 stitches were interrupted with “0” intestinal suture at the base under the longitudinal clamp to narrow the rectum and make it produce a postoperative The postoperative columnar scar will strengthen the columnar support of the rectum after injection. ② high interstitial injection around the rectum outside the anus: after the columnar suture, the rectum is sent back to the anus, if it is not easy to send back due to tissue swelling, the cotton pad can be wrapped and squeezed with both hands, on the one hand, so that the injected solution is evenly dispersed in the submucosal tissue, on the other hand, the rectal congestion can be improved, after the rectum is returned, the anal canal and perianal skin are disinfected with 10% thimerosal or iodophor, and then the aforementioned 1:1 anti-hemorrhoid solution is used on both sides The injection should be guided by the index finger into the anus to avoid necrosis of the intestinal wall and the occurrence of intestinal fistula. The perianal skin is disinfected with 10% thimerosal or iodophor and the perianal skin is disinfected with 10% thimerosal or iodophor, and the extent of reduction is decided according to the preoperative measurement of anal laxity, generally 1/2 of the anal canal is reduced by two horizontal fingers (diameter 100px), and 2/3 of the anal canal is reduced by three horizontal fingers (diameter 150px). (50 px in diameter), the posterior side is the flap to be reduced. A “∨”-shaped incision was made between the anal margin and the caudal bone from 1 cm on both sides of the anus in the truncated position, with a side length of about 5 cm, and the flap was subcutaneously free with scissors from the distal end to the anal margin and separated from the lower and superficial parts of the external sphincter skin, which was then seen to be relaxed and the anal caudal triangle angle increased. The lower part of the skin and the superficial muscle were sutured longitudinally with 3~4 stitches using a No. 4 silk thread to make the angle smaller and tighter against the anal canal. The wound is then moistened with iodophor and then carefully rinsed with saline to stop bleeding, and the “∨”-shaped skin incision is closed with No. 4 silk or absorbable sutures. When the suture reaches the anal edge, a “∧” incision is made downward from the dentate line to the original incision, only to the subcutis, and finally the “∨” and “∧” incisions are combined into a shuttle shape, and then the suture is continued from Then continue to suture from the outside to the inside until the top of the incision. After suturing, the anal canal can only be passed by a horizontal finger (50px in diameter) at most, and an oiled gauze strip or a rubber tube is placed inside the canal to drain it. If a rubber tube is used for drainage, a sterile drainage bag can be connected to the outer end. The results were evaluated according to the diagnostic efficacy standards of Chinese medicine in the national Chinese medicine industry. 64 of 67 patients were cured; 2 were improved; and 1 was invalid. There were no postoperative prolapse, perianal dampness, intestinal fistula, stricture, bleeding, urinary retention, sexual hypogonadism, and stool impaction in 56 cases (79%); urinary retention in 8 cases (12%), but the symptoms disappeared after a week of urinary catheterization; obstruction of defecation in 4 cases (6%); postoperative wound infection at the constricted anal canal, which was healed by timely stitch removal and drug change in 2 cases (3%). The patients’ hospital stay ranged from 15 to 37 d, with an average of 20 d. Analysis of the causes of early recurrence of single injection Complete rectal prolapse treated with a single injection method is effective in the near future, but the long-term effect is poor. In some cases, the symptoms of mucosal ectasia are as before within a short period of time. This is mainly due to the fact that the thickened rectal mucosa is still easy to dislodge and fold in the cavity until it flips out; after rectal mucosal injection, it does not change the angle of the rectal eccrine curve, resulting in the ability to support the rectum is not completely strengthened; after surgery, the patient’s loose anal caudal triangle is not effectively closed, and the contraction function of the anal canal is weakened, resulting in the anal canal still being “open “This results in easy recurrence. Our experience: intraoperative longitudinal columnar suture with mucosal layer is used to narrow the rectal cavity and produce columnar scar, which can play the role of columnar support for a longer period of time to prevent mucosal folding down; we use sclerosing agent to eliminate hemorrhoid injection in the posterior rectal space, and tighten the anal canal, and close the anal caudal triangle subcutaneously behind the anal canal, so that the angle of the external sphincter becomes smaller and tightens against the intestinal wall, in order to restore the perineal curvature of the rectum In order to ensure that the repaired sphincter does not tear during defecation in the short term, we also repair the skin of the anal canal together, thus also strengthening the local tension of the anal canal and ensuring the efficacy of the postoperative anal canal tightening. The site of injection to the perirectal area should be accurate and the dosage of drugs should be sufficient. Our experience is that both sides of the pelvic rectal gap and the posterior rectal gap should be fan-shaped and multi-angle when injected, and the injected site should be massaged with the index finger in the rectal cavity after injection to make the injected drug evenly dispersed, especially for the posterior rectal gap, the injection dose should be sufficient, and 15ml can be injected if necessary to make the rectal and sacral flexure adhesions dense. In addition, the intestinal tract should be well prepared before surgery, and the infection should be actively prevented after surgery, and the surface sutures should be removed in time in case of infection, so that the drainage is adequate and the muscle layer is avoided, and the two cases of infection in this group were cured, which is related to proper treatment.
