ABSTRACT
Objective@#To evaluate the long-term healing rate of transsphincteric anal fistula treated with anal fistula plug procedure and the risk factors affecting the healing of anal fistula.@*Methods@#A retrospective case-control study was conducted to analyze the clinical data of 207 patients with transsphincteric anal fistulas who received anal fistula plug procedure at the Department of General Surgery, Beijing Chaoyang Hospital of Capital Medical University from August 2008 to September 2012. Inclusion criteria: (1) consistent with the diagnosis of transsphincteric anal fistula: the anal fistula passed through the internal and external sphincter; (2) complete data; (3) initial treatment with anal fistula plug procedure. Exclusion criteria: (1) acute rectal or perianal infection or poorly controlled focal infection; (2) recent incision and drainage of perianal abscess or spontaneous rupture of abscess; (3) patients with malignant tumor; (4) patients with Crohn′s disease or ulcerative colitis; (5) patients with heart, liver, brain, lung or renal insufficiency; (6) cachexia due to various chronic wasting diseases; (7) patients could not tolerate surgery. Patients were followed up for anal fistula healing. The cumulative healing rate of patients with transsphincteric anal fistula was plotted using the Kaplan-Meier method, and the factors affecting anal fistula healing were explored by univariate and multivariate logistic regression analysis.@*Results@#There were 186 males and 21 females with age of 15 to 69 (mean 38) years. The duration of anal fistula was 3-60 (mean 15) months. Three patients had a history of previous episodes of perianal abscess and underwent incision and drainage of perianal abscess (all more than 3 months). During follow-up ending on October 31, 2018, 72 patients (34.8%) were lost to follow-up. Among 135 patients who were successfully followed up, the average follow-up period was 96 (75-124) months. Seventy-five patients had anal fistula healing, with healing rate of 55.6%. Kaplan-Meier survival curve showed that the healing time of anal fistula was prolonged and finally stabilized at 55.6%. In the patients who failed initial treatment with anal fistula plug packing, there were 6 cases whose anal fistula healed spontaneously without other treatment. Among them, 3 cases healed spontaneously 2 years and 3 cases 3 years after operation without recurrence. From 2008 to 2012, the annual healing rates of anal fistula plug treatment were 3/6, 61.5% (24/39), 42.1% (24/57), 12/15 and 12/18, respectively. Multivariate logistic regression analysis showed that the duration of anal fistula≥6 months (OR=3.187, 95% CI: 1.361-7.466, P=0.008) was an independent risk factor for anal fistula healing after treatment with anal fistula plug.@*Conclusion@#The long-term efficacy of anal fistula plug procedure in the treatment of transsphincteric anal fistula is positive, and this procedure should be implemented as soon as possible.
ABSTRACT
Objective To evaluate complications from two anal stapling operations of anorectal surgery,the procedure for prolapse and hemorrhoids (PPH) and the stapled transanal rectal resection (STARR).Methods The data of 1 276 patients undergoing PPH for hemorrhoids and 149 patients having STARR for ODS from January 2010 to January 2015,in Beijing Chaoyang Hospital were studied.More than six months of follow-up was done.Statistics used included t Test and Chi-square test,Logistic regression analysis.Results Complications of PPH and STARR included hemorrhage in 27 cases (2.1％) vs.3 cases (2.0％);pain in 285 cases (22.3％) vs.6 cases (4.0％);uroschesis in 96 cases (7.5％) vs.12 cases (8.1％);edema in 227 cases (17.8％) vs.16 cases (10.7％);defecatory urgency in 194 cases (15.2％) vs.38 cases (25.5％);anastomotic infection in 17 cases (1.3％) vs.2 cases (1.3％);mild anal incontinence in 11 cases (0.9％) vs.2 cases (1.3％);anastomotic stenosis in 11 cases (0.9％) vs.1 case (0.7％).There was a positive correlation between dry stool,defecatory urgency and hemorrhage after PPH.PPH compared to STARR:The post-operative pain,edema and defecatory urgency and overall complication rate was significantly different (t =26.51,x2 =4.69,x2 =10.38,x2 =37.12,P ＜ 0.05).Conclusions PPH and STARR have rare serious complications and easy to handle.Abnormal defecation such as dry stool and defecatory urgency is an important risk of hemorrhage.
ABSTRACT
Objective To investigate the clinical efficacy of ligation of intersphincteric fistula tract (LIFT) for the treatment of high anal fistula.Methods The clinical data of 77 patients with high anal fistula who were admitted to the Puren Hospital and Chaoyang Hospital from January 2011 to June 2012 were retrospectively analyzed.All the patients were treated using the LIFT method (LIFT group,37 patients) or fistulectomy + threaddrawing therapy (thread-drawing group,40 patients).The operation time,healing time,time and severity of postoperative pain,recurrence and anal sphincter dysfunction were compared between the 2 groups.The measurement data,the count data and the rank data were analyzed using the t test,chi-square test,and the rank sum test,respectively.Results The operation time of the LIFT group and the thread-drawing group were (21.4 ± 2.0) minutes and (20.6 ± 1.9) minutes,with no significant difference between the 2 groups (t =1.911,P ＞ 0.05).In the LIFT group,17 patients felt low-grade pain,no patient felt medium-grade or severe pain.In the thread-drawing group,7 patients felt low-grade pain,14 patients felt medium-grade pain,19 patients felt severe pain.The duration of postoperative pain in the LIFT group and the thread-drawing group were (3.0 ± 1.3) days and (14.1 ± 1.5)days,respectively.The severity and duration of postoperative pain of the LIFT group were significant lower and shorter than those of the thread-drawing group (u =-7.189,t =34.534,P ＜ 0.05).The healing time,anal scar area and anal sphincter function score were (26.0 ± 1.9) days,(1.24 ± 0.20) cm2 and 1 in the LIFT group,and (40.7 ± 2.8) days,(2.64 ± 0.25) cm2 and 4 in the thread-drawing group,with no significant difference between the 2 groups (t =26.574,26.868,Z =-7.513,P ＜ 0.05).The effective rate of the 2 treatment methods were 100％.The cure rate and recurrence rate were 51.4％ (19/37) and 5.4％ (2/37) in the LIFT group,and 42.5％ (17/40) and 2.5％ (1/40) in the thread-drawing group.There were no significant differences in the cure rate and recurrence rate between the 2 groups (x2=0.605,0.433,P ＞ 0.05).Conclusion LIFF method has higher cure rate for high anal fistula with short time of postoperative pain and healing,good anal sphincter function and low recurrence rate.
ABSTRACT
Objective To assess efficacy and safety of enhanced rehabilitation program for patients with colorectal cancer surgery. Methods One hundred and ten consecutive patients admitted to general surgery department at Beijing Chaoyang Hospital during October 2007 to October 2009 undergone with fasttrack colorectal cancer surgery and enhanced rehabilitation were prospectively studied, with 117 patients undergone with same colorectal cancer surgery by traditional perioperative treatment during May 2005 to September 2007 as controls. Restoration of their gastrointestinal function, occurrence of complications, fatality and length of hospital stay after surgical operation were observed in the group of enhanced rehabilitation and control group. Results Demographic characteristics, stage classification of illness and surgical operation methods were comparable in both groups. The first day with air discharge from the flux was earlier in enhanced rehabilitation group than that in controls (2. 5 vs. 3. 5 day after surgery, P ＜ 0. 05 ), and the former could tolerate solid food earlier than the latter (6.0 vs. 6.7 days after surgery, P=0.028). Overall morbidity of complications was less in the group with enhanced rehabilitation than that in controls (23.6% vs. 39. 3%,P =0. 011 ) and shorter length of hospital stay was observed in the former than that in the latter (9. 0 vs. 10. 8 days after surgery, P =0. 041 ). There was no difference in mortality, incidence of anastomotic leakage, and infectious and non-infectious complications between the two groups. Conclusions Enhanced rehabilitation program is safe and effective following colorectal cancer surgery to accelerate restoration of gastrointestinal function, reduce complications and shorten hospital stay after colorectal cancer surgery.
