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 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 summarize the latest research progress of intersphincteric fistula ligation in the treatment of anal fistula. MethodsThrough the retrieval of CNKI and PubMed literature database, the principle, clinical application and related improvement of LIFT were reviewed. ResultsLigation of intersphincteric fistula tract is a sphincter preserving surgery in recent years. 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 investigate long-term efficacy of infliximab (IFX) combined with seton placement in treatment of perianal fistulizing Crohn disease (CD) and to analyze factors affecting its clinical healing and recurrence.MethodsThe patients with perianal fistulizing CD underwent the IFX combined with seton placement therapy from July 2010 to January 2017 were collected from the HIS database of the Affiliated Hospital of Nanjing University of Traditional Chinese Medicine. The healing and recurrence of perianal fistulizing CD were counted and their influencing factors were analyzed.ResultsA total of 103 patients with perianal fistulizing CD were included in the study. After a median follow-up of 36 months, 64 patients (62.1%) had a complete fistula healing, 34 patients (33.0%) relapsed. The cumulative recurrence rates of fistula in the 1, 3, and 5 years was 21.8%, 32.6%, and 37.4%, respectively. The multivariate analysis showed that the Montreal classification B1 ［HR=3.987, 95% CI (1.640, 9.694), P=0.023］ and without abscess ［HR=2.724, 95% CI (1.101, 6.740), P=0.030］ were positively associated with the long-term healing of fistula, and the IFX maintenance treatment >3 times ［HR=5.497, 95% CI (1.197, 25.251), P=0.028］ was a risk factor for the recurrence of the fistula.ConclusionsLong-term healing rate of fistula by IFX combined with seton placement therapy is higher. Montreal classification B1, without abscess, and IFX maintenance treatment less than 3 times are expected to have a better long-term efficacy.
Objective To systematically evaluate the efficacy and safety for video-assisted anal fistula therapy in the treatment of complex anal fistula. Methods The databases of CKNI, Wanfang, VIP, CBM, Web of Science, PubMed, Cochrane Library and Embase were retrieved from the time of database establishment to may 31 2022. The two researchers independently screened the literatures and evaluated the quality of the literatures that met the inclusion criteria according to the research purpose and quality evaluation criteria. Meta-analysis were performed with the Revman 5.4.1 software. Results A total of 11 articles and 977 patients were included. The results of meta-analysis showed that the video-assisted group were superior to the traditional incision and thread hanging operation group in improved the cure rate [RR=1.14, 95%CI (1.04, 1.24), P<0.05], accelerated wound healing [MD=–10.40, 95%CI (–13.64, –7.17), P<0.05], protected the anal function after surgery [MD=–1.32, 95%CI (–1.85, –0.79), P＜0.05], relieved postoperative 24-hour pain [MD=–1.23, 95%CI (–1.60, –0.86), P＜0.05], shorten the operative time and hospital stay [MD=–9.46, 95%CI (–17.16, –1.75), P<0.05; MD=–3.87, 95%CI (–5.90, –1.84), P<0.05], reduced intraoperative bleeding [MD=–14.24, 95%CI (–17.49, –10.99), P<0.05] and the incidence of postoperative complications [RR=0.39, 95%CI (0.27, 0.56), P<0.05], which difference were statistically significant. However, there was no significant difference in the recurrence rate of 1-year after operation [OR=0.64, 95%CI (0.33, 1.23), P>0.05]. Conclusions Video-assisted anal fistula treatment is a safe and effective sphincter preserving operation for the treatment of complex anal fistula, which is superior to the traditional incision and thread hanging operation. However, due to the limitations and publication bias of the included literature, more prospective, large sample, multi center randomized controlled trial are needed to confirm its long-term efficacy.
Objective To summarize the research progression of video-assisted anal fistula treatment (VAAFT). Methods The related literatures in recent years were reviewed, and then the operation principle, operation process, advantages and disadvantages, matters needing attention, and clinical application of VAAFT were summarized. Results VAAFT is the treatment of fistulas by endoscopy. It don’t require the incision or resection of the fistula. It has the advantages of less surgical trauma, faster postoperative recovery, and less impact on the anal sphincter. The disadvantage of this method is relatively strict indications, fistula bending or horseshoe fistula is not suitable for this method. In addition, the endoscope using during the operation is a rigid mirror tube, and the operation is not convenient enough, so technical improvement is needed in the future. We should pay attention to distinguish true fistula and false fistula in clinical practice; the wall of the fistula should be adequately burned and the necrotic tissue should be cleaned; the treatment of the internal opening of anal fistula must be exact; the time of the first defecation should be appropriately delayed, and the incidence of infection should be reduced after operation. At present, the clinical reports of VAAFT are increasing gradually in foreign countries, and these reports have achieved good therapeutic effect. It is considered that this method maybe a safe and effective minimally invasive surgical treatment for anal fistula. However, there is few clinical reports on VAAFT in China, and it is still in the preliminary stage of exploration. Conclusion VAAFT is a new technology in the treatment of anal fistula, and it has advantages of minimally invasive, sphincter preservation, and so on, which is worthy of clinical application.
Objective To evaluate the value of magnetic resonanace imaging (MRI) on the diagnosis of complex anal fistula. Methods The preoperative digital examination and MRI with the phased-array coil were implemented for 22 patients who were clinically suspected with complex anal fistula. The final diagnosis were based on surgical findings. Outcomes of MRI and digital examination were compared with surgical results. Results Eighteen patients were diagnosed as complex anal fistula, 1 case of presacral cyst and 3 cases of chronic anorectal fistula combined with perianal mucinous adenocarcinoma. All the patients were correctly diagnosed by MRI, while the patients with presacral cyst and perinaal mucinous adenocarcinoma could not be diagnosed correctly by digital examination. According to the Parks classification, 3 patients suffered from transsphincteric fistula, 11 cases of supra-sphincteric and 5 cases of extra-sphincteric fistula. The diagnosis rates of the internal opening with digital examination and MRI were 33.3% and 72.2%, the rates of the primary tract were 83.3% and 100%, and the rates of the secondary extensions were 16.7% and 88.9%, respectively. The differences in detection of internal opening and secondary extensions between MRI and digital examination were significant (P=0.019, P=0.000), the difference in detection of primary tract was no significant (P=0.072). Conclusion MRI with the phased-array coil can develope the high accuracy in the diagnosis of complex anal fistulas, and reveal the relationship between anorectal sphincters and the complex fistula.
