ObjectiveTo analyze the effect of anal fistula clip (AFC) in the treatment of anal fistula, and to evaluate its safety. MethodsA historical cohort study method was conducted. Eighty-three patients with glandular transsphincteric anal fistula in the Xuzhou Central Hospital from September 2018 to May 2021 were collected, of which 42 patients underwent the AFC treatment (AFC group), 41 patients underwent the endorectal advancement flap (ERAF) treatment (ERAF group). The operation time, intraoperative blood loss, visual analogue scale (VAS) score of anus pain on postoperative day 1, 3, and 7, wound healing time, Wexner incontinence score of anal function on postoperative month 6, and clinical efficacy (healing and failure) were compared between the two groups. ResultsThe operation was successfully completed in both groups. The operation time and intraoperative blood loss in the AFC group were shorter or less than those in the ERAF group (P<0.05). No complications such as internal opening infection and bleeding occurred in the two groups. There were no statistical differences in the VAS score of postoperative anus pain at all time point between the two groups (P>0.05). The median follow-up time was 22 months. There was no statistical difference in the wound healing time between the two groups (P>0.05). The Wexner score of anal function in the AFC group was lower than that in the ERAF group (P<0.05), and there was no statistical difference between after operation and before operation (Z=–1.751, P=0.089) in the AFC group, while that in the ERAF group after operation was higher than before operation (Z=–1.859, P=0.014). The healing rate had no statistical difference between the AFC group and ERAF group (85.7% versus 77.5%, χ2=0.925, P=0.336). Conclusion From the results of this study, the AFC is safe and effective in treatment of anal fistula, with the advantages of relatively simple operation, less bleeding during operation, lighter postoperative pain, and good protection of anal function.
Eighteen paticnts (17 females and 1 male ) with acguired preanal fistula were treated surgically. The ages ranged from 4 months to 12 years. Their locations were between the anorectum and the vestibulum (12 cases), the anorectum and the labia (2 cases), the anorectum and the vagina (3 cases), and the anorectum and the urethra (1 case). All of them were tueated by intraectal repair. The surgical procedures were briefly discused. The operation could be used in all types of acquired preanal fistula and has no danger of trauma to the anal sphincter and posterior vaginal wall. A long term follow-up study of 7 patients showed that there was a cure in 18 cases with normal function.
ObjectiveTo understand progress of stem cell transplantation in treatment of complex anal fistula.MethodThe relevant literatures were searched in the PubMed, Web of Science, CNKI, Wanfang, and other databases and the clinical efficacy, advantages and problems of the therapy were analyzed and summarized.ResultsThe stem cells currently used in the field of complex anal fistula were mainly the adipose tissue-derived stem cells, which had the biological characteristics of regenerative differentiation, immune regulation, and repair of intestinal mucosal barrier, which could be used as the seed cells for the treatment of complex anal fistula, its effectiveness was worthy of recognition. But its long-term clinical efficacy remained to be seen due to its clinical treatment options were different and lack of uniform standards. The safety of treatment for complex anal fistula was payed a attention because the stem cells had the oncogene activation and tumor suppressor gene inactivation characteristics.ConclusionsStem cell transplantation, as an emerging therapy, has broad prospects for patients with complex anal fistula that are difficult to solve by surgery, but its long-term efficacy is still unsatisfactory. Due to current sample size, short observation time, and lack of randomized control, current clinical data is not convincing, and high cost also limits its development of technology.
ObjectiveTo observe the effect of modified ligation of intersphincteric fistula tract (LIFT) combined with acellular anal fistula repair matrix packing in the treatment of high anal fistula, and to evaluate its clinical efficacy and safety.MethodsAll 86 patients who met the diagnostic criteria of high anal fistula in Beijing Anorectal Hospital from October 2018 to August 2019 were selected and randomly divided into observation group and control group. The observation group was treated with modified LIFT combined with acellular anal fistula repair matrix tamponade, while the control group was treated with traditional low incision and high thread drawing surgery. The curative effect, wound healing time, postoperative pain score, intraoperative blood loss, postoperative complications, hospitalization time, patient satisfaction and recurrence at 6 months after operation were compared between the two groups.ResultsThe effective rate of the observation group was 92.9% (39/42), and that of the control group was 86.4% (38/44), there was no significant difference between the two groups (Z=−1.251, P=0.211). The healing time of the observation group and the control group were (24.8±8.5) days and (32.1±10.9) days, respectively, the difference was statistically significant (t=3.472, P<0.001). Compared with the control group, the observation group had less intraoperative blood loss, less postoperative pain and shorter hospital stay (P<0.05). There was no anal incontinence after operation in the two groups, and the incidence of postoperative complications such as bloody stool, anal border edema and urinary retention were lower in the observation group (11.9%) compared with the control group (31.8%), with a statistically significant difference (P<0.05). The treatment satisfaction of the observation group was 90.5%, and that of the control group was 81.8%. There was no significant difference between the two groups (Z=−1.284, P>0.05).ConclusionModified LIFT combined with acellular anal fistula repair matrix in the treatment of high anal fistula has the advantages of small trauma, quick recovery and low incidence of complications.

Because it has the advantage of ensuring the integrity of the sphincter, less damage to the anal function after operation, the wound healing quickly and so on, it has been accepted by domestic and foreign scholars. ConclusionLIFT to cure anal fistula while ensuring the anal function integrity, is the development trend of anal fistula surgery, is worthy to be popularized.
ObjectiveTo explore the influence of individualized psychological nursing in perioperative patients with high complex anal fistula on their perioperative anxiety, depression, pain, and recovery. MethodsFifty-seven perioperative patients with high anal fistula treated between May 2011 and March 2012 were randomly divided into observation group (n=28) and control group (n=29). Patients in the control group were treated with traditional way of psychological nursing intervention, while patients in the observation group were given individualized psychological nursing intervention. Then, we compared the two groups of patients in terms of their perioperative anxiety, depression, and pain as well as the length of hospital stay, hospital expenses, wound healing time, and patients' quality of life. ResultsOn the day of surgery and on day 7 after surgery, anxiety, depression and pain scores of the observation group were significantly lower than those of the control group (P<0.05). Length of hospital stay and hospitalization expenses of the observation group were significantly shorter or less than the control group (P<0.05). There was no statistically significant diTherence between the two groups in postoperative wound healing time (P>0.05). The quality of life score for both the two groups of patients after treatment was significantly higher than that before treatment (P<0.05), but there was no statistically significant diTherence between the two groups (P>0.05). ConclusionIndividualized psychological nursing can relieve perioperative adverse psychological reactions such as anxiety, depression and pain, and promote postoperative recovery for patients with high complex anal flstula.
ObjectiveTo explore the clinical efficacy and safety of ligation of intersphincteric fistula tract in the treatment of high simple anal fistula.MethodsA prospective collection of 72 patients diagnosed with high simple anal fistula, who admitted to the department of the author’s hospital between March 2015 and December 2017 was performed, and then the patients were divided into two groups according to the random number table method combined with the patients’ wishes: the ligation of intersphincteric fistula tract group (experimental group, 32 cases) and the low incision and high hanging group (control group, 40 cases). Comparison of indexes on the operative effect and physiological function of the sphincter in six months after operation was performed.ResultsCompared with the control group, the patients in the experimental group had short postoperative pain duration, short postoperative wound healing time, high cure rate, low recurrence rate, low initial sensory threshold, high anal resting pressure, and long anal high pressure band length, with statistically significant differences (P<0.05). However, there was no statistically significant difference between the two groups in the operation time, anal maximal contractive pressure, and rectal resting pressure (P>0.05). The results suggested that the physiological function of anus in the experimental group recovered well.ConclusionThe ligation of intersphincteric fistula tract is a safe and reliable method in the treatment of high simple anal fistula, which can be widely used in the clinic.
ObjectiveTo investigate effect of preoperative three-dimensional anorectal endosonography (3D-AREUS) in anal fistula surgery.MethodsA total of 100 patients with anal fistula who were admitted to the Chaoyang Central Hospital from December 2017 to December 2018 were included prospectively, then were randomly divided into ultrasound group and control group with 50 cases in each group. The preoperative examination was performed by 3D-AREUS in the ultrasound group, and preoperative routine examination, finger examination or probe exploration were performed in the control group. The postoperative recurrence and anal functions were compared between the two groups.ResultsThere were no statistically significant differences in the gender, age, body mass index, anal surgery history, preoperative anal function, etc. between the two groups (P>0.05). The detection rate of branch fistulas in the ultrasound group was significantly higher than that in the control group (P=0.025). For the patients with complex anal fistula, compared with the control group, the location accuracy rate of internal opening was higher (P=0.014), the change value of preoperative and postoperative fecal incontinence score was lower (P=0.039), anorectal pressure status (resting pressure of anal canal, anal systolic pressure, and length of anal high pressure zone) were lower (P<0.05) in the ultrasound group; For the patients with simple anal fistula, which had no significant differences between the ultrasound group and control group (P>0.05). There were 4 cases of recurrence in each group.ConclusionsFor complex anal fistula, preoperative 3D-AREUS could clarify position of internal opening, presence of branching fistula, and the relationship between fistula and sphincter, so as to make accurate surgical plans, reduce secondary injuries, and retain postoperative anal function of patients.
ObjectiveTo compare clinical efficacy of 4 kinds of surgical treatment for high transsphincter fistula. MethodsThe clinical data of 116 patients with high transsphincter fistula in Jiangsu Province Hospital of TCM from January 2012 to December 2014 were analyzed retrospectively.These patients were divided into 4 groups according to surgical treatments,including cut seton group (n=30),loose seton group (n=34),ligation of intersphincteric fistula tract group (LIFT,n=41),mucosa advancement flap group (MAF,n=11).The length of stay,incision healing time,postoperative pain score on the second day,Wexner score when healed,postoperative complications,curative status,and recurrence were observed. Results① The length of stay in the loose seton group was significantly longer than that in the LIFT group (P<0.01),cut seton group (P<0.05) or MAF group (P<0.05),but which had no differences among the other groups (P>0.05).② The incision healing time in the loose seton group was significantly longer than that in the LIFT group (P<0.01) or the MAF group (P<0.05),but which had no differences among the other groups (P>0.05).③ The postoperative pain score on the second day in the cut seton group was significantly higher than that in the other three groups (P<0.01),which in the MAF group was lower than that in the LIFT group (P<0.05),but which had no difference between the other groups (P>0.05).④The Wexner score when healed in the cut seton group was significantly higher than that in the other three groups (P<0.01),bwt which had no differences among the other groups (P>0.05).⑤ The rate of postoperative complica-tion in the LIFT group was significantly higher than that in the loose seton group (P<0.05),but which had no differences among the other groups (P>0.05).⑥ The curative rate and recurrence rate had no statistically differences among the 4 groups (P>0.05). ConclusionsCurative rate and recurrence rate in loose seton,LIFT,and MAF group are similar with cut seton group,meanwhile they could protect anal function better and relieve pain.The length of stay and the incision healing time are longer in the loose seton group.The postoperative complications in LIFT group is increased as compared with loose seton group.The postoperative pain of MAF group is slighter than that in LIFT group.Comprehensive evaluation,MAF has more advantages,but the technique is more complex.The decision should be made individually according to patients and surgeons.
