ObjectiveTo investigate the influence of surgical treatment on early postoperative anal function in left colon cancer patients with acute complete obstruction. MethodsThe clinical data of left colon cancer patients with acute complete obstruction were retrospectively chosen from January 2017 to June 2020 in Yibin Second People’s Hospital. The patients were grouped according to the treatment plan including emergency operation group (54 cases), stent+operation group (46 cases) and stent+neoadjuvant chemotherapy (NAC)+operation group (44 cases). The anal function was evaluated at 4 weeks, 1 month and 6 months after operation, and quality of life was evaluated at 12 months after operation. Unconditional logistic regression model was used to explore the factors influencing early postoperative anal function injury. Results The proportion of open surgery in the emergency operation group was statistically higher than the stent+operation group and stent+NAC+operation group (P<0.05). The low anterior rectum resection syndrome (LARS) score at 4 weeks after operation of the emergency operation group was statistically higher than those of the stent+operation group and stent+NAC+operation group (P<0.05). However there was no statistical difference in LARS score at 1 month and 6 months after operation among the three groups (P>0.05). The score of social function in the emergency operation group at 12 months after operation was statistically lower than those of the stent+operation group and stent+NAC+operation group (P<0.05). Multivariate logistic regression analysis showed that body mass index (BMI) ≥24 kg/m2, emergency operation, and Eastern Collaborative Oncology Group (ECOG) score were the risk factors for early postoperative anal dysfunction in the left colon cancer patients with acute complete obstruction (P<0.05). ConclusionsLeft colon cancer patients complicated with acute complete obstruction who only received emergency surgery, BMI≥24 kg/m2, or one score of ECOG are more likely to have functional impairment, and the quality of life of those patients underwent emergency surgery alone is decreased. In addition, the stent placement at the obstruction site should be helpful to avoid the above problems.
ObjectiveTo investigate the curative effect of C-shaped mucosal resection and anastomosis above the dentate line in the treatment of mixed hemorrhoids and its effect on anal function. MethodsA total of 78 patients with degree Ⅳ mixed hemorrhoids treated in Nanjing Liuhe District People’s Hospital from June 2015 to February 2018 were retrospectively collected. The patients were divided into control group (n=39) and observation group (n=39) according to treatment methods. Patients of the control group received traditional procedure for prolapse and hemorrhoids operation, while patients of the observation group received C-shaped mucosal resection and anastomosis above the dentate line. The perioperative indexes (operation time, intraoperative blood loss, hospital stay, etc.), subjective function evaluation indexes (Wexner constipation score, Kirwan grade, etc.), clinical efficacy and recurrence rate were compared between the two groups. The random walking model was used to evaluate the clinical curative effect. ResultsThe intraoperative blood loss [(27.9±3.4) mL vs. (43.2±5.2) mL, P<0.001], 24 h visual analogue scale score [(4.2±1.5) points vs. (5.6±1.5) points, P<0.001], duration of first defecation pain [(22.1±3.2) min vs. (34.2±5.0) min, P<0.001], the time of carrying blood [(4.1±0.4) d vs. (5.7±0.6) d, P<0.001], and the time of edema [(3.2±0.6) d vs. (4.7±0.9) d, P<0.001] in the observation group were shorter (lower) than those in the control group. The difference between pre-and post-operation of Wexner constipation score [(13.2±2.4) points vs. (11.7±2.1) points, P=0.004], resting pressure [(23.1±4.9) mmHg vs. (17.8±3.4) mmHg, P<0.001] and maximum squeeze pressure [(33.5±7.3) mmHg vs. (23.1±5.6) mmHg, P<0.001] in the observation group were significantly higher than those in the control group. There was a long-term correlation between changes in random fluctuating power rate values of Wexner constipation score, Kirwan grade, rectoanal inhibitory reflex positive rate, resting pressure, maximum squeeze pressure and the surgical procedure received by the patient of the two groups. The total effective rate [97.4% (38/39) vs. 66.7% (26/39)] and non-recurrence rate [92.3% (36/39) vs. 76.9% (29/39)] in the observation group were higher than those in the control group, while there was no significant difference in the incidence of total complications between the two groups [5.1% (2/39) vs. 12.8% (5/39), P=0.235)]. ConclusionCompared with PPH, C-shaped mucosal resection and anastomosis above the dentate line for the treatment of degree Ⅳ mixed hemorrhoids can improve the therapeutic effect, reduce postoperative recurrence, maintain anal function and facilitate the recovery of patients.
Objective To investigate the application of gluteus maximus transplantation for fecal incontinence after surgery of high anal atresia. Methods Between December 2002 and November 2010, 25 patients with fecal incontinence were treated with gluteus maximus transplantation, which was caused by surgery of high anal atresia. There were 11 malesand 14 females with an average age of 10.2 years (range, 3-22 years). Preoperative radiography, anorectal manometer, and electromyogram showed abnormality or deficiency of anal sphincter function. Wexner score, Fecal Incontinence Quality of Life (FIQL) questionnaire, and Self-rated Health Measurement Scale Version 1.0 (SRHMS) score were used to evaluate l ife qual ity of the patients. The anorectal manometer, intra-rectal ultrasound examination, and defecation radiography were performed. Results Healing of incision by first intention was achieved in 23 cases and rectal-wound fistula occurred in 2 cases. The follow-up time was 1 to 9 years (mean, 6.3 years). Defecation frequency was decreased from more than 10 times to 4-6 times every day. Wexner score and SRHMS were significantly improved at 1 or 2 years after surgery when compared with preoperative socres (P lt; 0.05). FIQL was also significantly improved after 2 years (P lt; 0.05). At 2 years after surgery, the anal maximum systol ic pressure, contraction duration, and maximum systol ic volume were improved, showing significant differences when compared with those at preoperation and 1 year after surgery (P lt; 0.05). Conclusion Gluteus maximus transplantation can improve defecation controls in the patients with fecal incontinence after surgery of high anal atresia.
ObjectiveTo observe and assess the therapeutic effect of posterior amputation of internal sphincter and partial external sphincter in the treatment of old anal fissure. MethodsEighty patients with old anal fissure treated between August 2012 and June 2014 were randomly divided into study group and control group with 40 in each. The study group received posterior amputation of internal sphincter and partial external sphincter, while the control group underwent single amputation of internal sphincter. Then we observed the cure rate, wound healing days, pain at defecation after operation, defecation control after operation, and long-term recurrence rate. ResultsAll the 40 patients in study group were healed with a recovery rate of 100%, while 38 in control group were healed with a recovery rate of 95%; the difference between the two groups were not significant (P>0.05). The wound healing time in study group[(17.0±3.5) days] was much longer than that in the control group[(10.5±3.8) days] (P<0.05). The pain extents of fundament during defecating on the first day and 3, 7, and 15 days later in study group were more alleviated than those in the control group (P<0.05). In the six-month follow-up period, one patient in study group had liquid stools out of control 3 months after the surgery, and the others had no similar symptoms (P>0.05). ConclusionPosterior amputation of internal sphincter and partial external sphincter is a reasonable method for the treatment of old anal fissure. It can not only cure old anal fissure but also alleviate pain at defecation after operation and facilitate defecation.
ObjectiveTo compare the efficacy of totally transanal endorectal pull-through and laparoscopic assistance endorectal pull-through in the treatment of Hirschsprung’s disease (HD).MethodsPubMed, EMBASE, The Cochrane Library, CNKI, Wanfang, and VIP Database were searched to screen out the comparative studies published between January 1998 and May 2020 on the treatment of HD with totally transanal endorectal pull-through and laparoscopic assistance endorectal pull-through. Then two reviewers independently completed the literatures screening, data extraction, and quality evaluation. The Review Manager 5.3 software was used to combine the effect size of the postoperative effect indicators included in the literatures. Stata 14.0 software was used to perform Begg’s and Egger’s tests on the publication bias of the included literatures.ResultsA total of 8 clinical studies conforming to the standards were included and 702 cases of children undergoing HD radical resection were recorded, including 335 cases in the totally transanal endorectal pull-through group and 367 cases in the laparoscopic assistance endorectal pull-through group. Compared with the laparoscopic assistance endorectal pull-through group, the totally transanal endorectal pull-through group had an advantage in the incidence of postoperative faecal incontinence/soiling [OR=0.20, 95%CI was (0.07, 0.54), P=0.001], and the postoperative constipation recurrence rate was higher than the laparoscopic assistance endorectal pull-through group [OR=2.39, 95%CI was (1.05, 5.42), P=0.04]. There were no statistically significant differences between the two groups in terms of postoperative enterocolitis [OR=1.01, 95%CI was (0.59, 1.75), P=0.96], postoperative adhesion intestinal obstruction [OR=0.74, 95%CI was (0.28, 1.95), P=0.54], and postoperative anastomotic stenosis [OR=1.14, 95%CI was (0.51, 2.56), P=0.74].ConclusionsCompared with laparoscopic assistance endorectal pull-through, the totally transanal endorectal pull-through can reduce the incidence of postoperative faecal incontinence/soiling, but the rate of recurrence of postoperative constipation is higher. The two surgical procedures for HD have similar incidences of postoperative enterocolitis, anastomotic stenosis, and adhesive intestinal obstruction.
ObjectiveTo evaluate the postoperative anal function of rectal cancer patients treated with transanal total mesorectal excision (taTME), and to analyze the influencing factors which resulted in low anterior resection syndrome (LARS) after taTME in this paper, so as to provide guidance for clinical practice.MethodsThe data about the patients with rectal cancer treated with taTME were collected at the Affiliated Nanchong Central Hospital of North Sichuan Medical College from December 2018 to December 2019, including the clinical data and follow-up data. Postoperative recovery condition of the patients’ anal function and the affecting factors caused the occurrence of severe LARS after taTME were analyzed. The patients’ anal function within 1, 6, and 12 months after taTME were evaluated, and the evaluation tools were LARS scale and Wexner scale. The follow-up period was up to December 30, 2020.ResultsA total of 67 patients were completed preoperative and postoperative follow-up at 1, 6, and 12 months. In terms of anal function, within 1 month after taTME was the worst period in which the anal function was the worst among all the points of time evaluated (1.49±0.33, 10.28±0.64, 6.42±0.60, and 3.73±0.61, respectively), and there was time trend during the follow-up period (F=66.101, P<0.001). In the first year after taTME, the patient’s anal function was in a state of continuous recovery, and the differences between the three points of time at 1, 6, and 12 months after taTME and preoperative anal function were statistically significant (P<0.010). The results of multivariate analysis indicated that the distance between the anastomotic stoma and the anal verge was independent risk factor affecting the postoperative anal function of the patients with taTME at 1 month and 6 months (P<0.010).ConclusionsWith time going, the postoperative anal function of the patients with taTME can be recovered to a certain extent. The distance between the anastomotic stoma and the anal verge was the independent factor affecting the postoperative function of the rectal cancer patients received taTME.
Objective To study the safety and feasibility of modified laparoscopic Dixon surgery for rectal cancer. Methods In the procedure of modified laparoscopic Dixon surgery, the rectum with tumor was pulled out and cut and colon-rectum anastomosis was performed through anus. The clinical data of patients with rectal cancer between modified laparoscopic Dixon surgery (laparoscopy group) and open Dixon surgery (open group) were compared and analysed prospectively. The clinical data included operative time, volume of bleeding, number of lymph node dissection, volume of abdominal drainage, time to bowel gas passage, hospital stay and relative complications, such as anastomotic leakage, ureteral injury, dysuria and fecal incontinence. Results Fifty-eight cases were selected in this study between September 2007 and July 2008, including 25 laparoscopic surgery in laparoscopy group and 33 open surgery in open group. Patient’s data on gender, age, distance between tumor and anus edge, tumor diameter, tumor pathologic type and Dukes stage were similar between two groups by statistic analysis (Pgt;0.05). All the operations were performed successfully. Two cases experienced anastomotic leakage in laparoscopy group, while 1 case experienced anastomotic leakage in open group. All these patients got recovered by conservative treatment at last. No other complications were experienced, such as ureteral injury, dysuria, fecal incontinence, and so on. There were no significant differences in term of operative time, volume of bleeding and number of lymph node dissection between two groups (Pgt;0.05). The volume of abdominal drainage was less while the time to bowel gas passage and hospital stay were shorter in laparoscopy group than those in open group (P＜0.05). Conclusion This study reveals that it is safe and feasible to perform modified laparoscopic Dixon surgery for rectal cancer, and it presents the character of minimal invasion.
ObjectiveTo summarize the occurrence of anal fistula in Crohn disease (CDAF) accompanying with preoperative rectal stenosis and analyze its influencing factors. Meanwhile to explore the effect of improved anal sphincter retention virtual-hanging (hereafter this text will be abbreviated as virtual-hanging) for treatment of CDAF. MethodsThe CDAF patients admitted to the Third People’s Hospital of Bengbu from January 2019 to June 2021 were retrospectively collected, who were treated with virtual-hanging. Meanwhile the multivariable logistic regression analysis was used to identify the risk factors for accompanying with preoperative rectal stenosis and which were used to establish a decision tree model by Chi squared automatic interaction detection method. ResultsA total of 234 patients with CDAF were collected, and the incidence of accompanying with preoperative rectal stenosis was 22.2% (52/234). The multivariate logistic regression analysis found that the patients with preoperative proctitis, Montreal subtype B2, fistula located above the musculi levator ani (MLA), single fistula accompanied by branches or multiple fistulas, lymphocyte count (Lym) ≥6.03×109/L, platelet count (PLT) ≥0.61×109/L, erythrocyte sedimentation rate (ESR) ≥39.11 mm/h, C-reactive protein (CRP) ≥5.13 mg/L, and brain natriuretic peptide (BNP) ≥313.26 ng/L had higher probability of accompanying with preoperative rectal stenosis (P<0.05). For the patients with or without preoperative rectal stenosis, the CD activity index score and perianal CD activity index score, and anal resting pressure all showed decreasing trends after treatment with the virtual-hanging, and the anal maximal contraction pressure showed a increasing trend as compared to before treatment. The decision tree consisted 18 nodes and 9 terminal nodes. The gain map of the decision tree model gradually increased from 0% to 100%; The index chart maintained a high level starting from 198% and then rapidly decreased to 100%. The area under the receiver operating characteristic curve of the decision tree model was 0.852 [95%CI (0.821, 0.908)], with a sensitivity of 84.35% and a specificity of 82.33%. ConclusionsThe incidence of accompanying with preoperative rectal stenosis in patients with CDAF is relatively higher. The effect of virtual-hanging for treatment of CDAF is better. For patients with preoperative proctitis, Montreal subtype B2, fistula above the MLA, single fistula accompanied by branches or multiple fistulas, and higher Lym, PLT, ESR, CRP, and BNP, attention should be paid to their accompanying with preoperative rectal stenosis. The decision tree model based on these factors to distinguish whether accompanying with preoperative rectal stenosis is better.
Objective To investigate the applied significance of adjustable low-concentration of mixed oxygenand nitrous oxide inhalation sedation combined with lidocaine local anesthesia in anorectal surgery. Methods Three hundreds patients underwent anorectal surgery in our hospital were divided into control group （n=154） and observation group （n=146）. Patients of control group underwent pure lidocaine local anesthesia， and patients of observation group underwent mixed oxygen and nitrous oxide sedation analgesia combined with lidocaine local anesthesia. Vital signs before and after operation as well as results of sedation and analgesia were compared between the 2 groups. Results Anorectal surgeries of all patients were performed successfully. There were no significant differences on change of heart rate， blood pressure， and oxygen saturation between the 2 groups before and after operation （P＞0.05）. The operation time between the control group 〔（36.3±6.8） min〕 and observation group 〔（35.4±6.5） min〕 had no statistically significant difference（t=-0.607， P=0.544）. The analgesic effects （Z=-6.859， P=0.000） and sedative effects （Z=-5.275， P=0.000） of obser-vation group were both better than those of control group. Conclusions Low-concentration of mixed oxygen and nitrous oxide inhalation sedation combined with lidocaine local anesthesia can relieve the discomfort of fear and pain， no side-impacts on vital sign before and after operation were observed，and it has better effects of sedation and analgesia， therefore it can be recommended to clinical application.
