Objective:To compare the clinical efficacy of laparoscopic pelvic floor three-level internal repair and stapled transanal rectum resection (STARR) in the treatment of male patients with intrarectal prolapse. Mlethds A total of 101 male patients with rectal intrarectal prolapse from Feb 2013 to Oct 2017 were enrolled into this study. Fifty-two patient in group A received laparoscopic pelvie floor three-level internal repair, and 49 patients in group B received STARR. The Wexner incontinence scale (WIS), Wexner constipation scale (WCS) score, gastrointestinal quality of life index (GIQLI) and degree of internal rectal prolapse (DIRP) were systematically evaluated before surgery and 3 months, 1 year and 3 years after surgery. Results:There were no significant differences in age, BMI, number of bowel movements(BM), WIS, WCS, GIQLI and DIRP between the two groups before surgery(all P>0.05). The WIS, WCS, GIQLI and DIRP in 3 months, 1year and 3 years after surgery in both two groups were significantly better than those before surgery ( t=20.169, 25.229, 27.278, 23.818, 23.489, 21.152, -3.550, -23.042, -22.901, 82.852, 40.915, 30.010, 11.323, 13.237, 11.452, 19.473, 18.647, 17.108, -8.791, -5.254, -5.846, 37.439, 30.598, 22.852, all P<0.001). The GIQLI in Group A was significantly better than that of group B at 1 year and 3 years after surgery ( P<0.001) but close to that in Group B at 3 months after surgery ( t=1.428, P=0.156). The WIS, WCS and DIRP in group A were significantly better than those in group B at 3 months, 1 year and 3 years after surgery, with statistical significance ( t=-8.243, -15.688, -20.193, -4.268, -4.768, -4.851, 11.329, 13.543, -5.399, -4.745, -4.598, all P<0.001). There was no signifcant difference in grade Ⅰ-Ⅲ complications between the two groups (χ 2=0.046, P=1.00). Conclusion:Laparoscopic pelvic floor three-level internal repair is more effective than transanal STARR in the treatment of male internal rectal prolapse.

Objective:To compare the clinical efficacy of laparoscopic integral pelvic floor/ligament repair (IPFLR) combined with a procedure for prolapse and hemorrhoids (PPH) and that laparoscopic IPFLR alone in the treatment of internal rectal prolapse (IRP) in women.Methods:Patients were divided into groups A in which 63 patients undergoing laparoscopic IPFLR alone, and group B of 67 patients reciving laparoscopic IPFLR combined with PPH. The degree of internal rectal prolapse (DIRP), Wexner constipation scale (WCS) score, Wexner incontinence scale (WIS) score, and Gastrointestinal Quality of Life Index (GIQLI) score were compared between these two groups and in each group those before surgery and 6 months, 2 years, and 5 years after surgery.Results:The number of bowel movements , DIRP, WCS score, WIS score, and GIQLI score before surgery were not significantly different between the two groups (all P>0.05). The DIRP, WCS score, WIS score, and GIQLI score in each group 6 months, 2 years, and 5 years after surgery in both two groups were significantly better than those before surgery (all P<0.001). The DIRP, WCS score, WIS score, and GIQLI score in group B were significantly better than those in group A at 6 months, 2 years, and 5 years after surgery (all P<0.05) except DIRP at 2 years after surgery (all P<0.05). There was a significant difference in the recurrence rate of IRP between the two groups when evaluated at 5 years after surgery ( P=0.001). Conclusions:Integral theory-guided laparoscopic IPFLR combined with PPH has a higher cure rate and a better clinical efficacy than laparoscopic IPFLR alone.

Objective:To evaluate pelvic floor holistic theory used in the treatment of complete rectal prolapse (CRP).Methods:Forty-two CRP patients at No. 989 Hospital between Oct 2015 and Jun 2019 were divided into group A ( n=23) treated by laparoscopic rectopexy associated with the procedure for PPH, and group B ( n=19), by Altemeier precedure. The degree of rectal prolapse, Wexner fecal incontinence score and Wexner constipation score were evaluated before operation and at the 6th,12th and 24th months after operation Results:The operation time of the two groups were (53±6) and (90±9) min; intraoperative blood loss was (14±5) and (80±19) ml; the hospital stay was (8.9±1.7) and (13.5±2.1)d, all P<0.05. There was no significant difference in postoperative recurrence between the two groups ( P>0.05). The degree of rectal prolapse in group A and B were (9.5±1.7) and (8.7±1.5)cm; the 6 th, 12 th and 24 th months after operation were [(-1.0±1.6), (-0.2±1.8)cm; (-1.0±1.3), (-0.3±1.5)cm; (-0.8±1.2), (-0.5±1.6)cm], all P<0.05. The preoperative constipation in group A and group B was (6.4±1.7) and (6.4±1.5) respectively; the 6 th, 12 th and 24 th months after operation were [(2.8±1.0) vs. (3.0±1.3); (2.6±1.1) vs. (2.8±1.3); (2.0±0.9) vs. (2.3±1.1)], all P<0.05. The preoperative fecal incontinence score of group A and group B were (7.6±1.7) vs. (7.1±1.5); the 6 th, 12 th and 24 th months after operation were [(3.7±1.7) vs. (3.4±1.2); (3.5±1.8) vs. (3.1±1.1); (3.4±1.9) vs. (2.6±1.3)], all P<0.05. Conclusion:Pelvic floor holistic theory help improve the treatment of complete rectal prolapsed.

Objective:To investigate the diagnosis, surgical methods, perioperative treatment and surgical results of Kommerell's diverticulum with double aortic arch in infants.Methods:From December 2014 to December 2019, 22 cases of double aortic arch combined with Kommerell diverticulum were operated in our hospital, 14 males and 8 females, with an average age of (13.7±11.6) months (1-36 months) and mean body mass of (9.8±3.4)kg (5-20 kg). The children had respiratory symptoms such as asthmatic suffocation, shortness of breath, repeated respiratory tract infection and chronic cough before operation. All patients underwent cardiac CT examination. The average diverticulum was 8 mm×9 mm, in the trachea The average compression degree of the lower segment was 56%±16% (30%-80%). The distal part of the left arch was atresia and Kommerell's diverticulum was found in all patients. The operation methods were left aortic arch separation, ligament separation and diverticulectomy. In one case, tracheal stent was placed simultaneously during the operation because of severe tracheal malacia.Results:The average time in the ward was(1.4±0.8)days (1-4)days, and the average time in hospital was (6.7±2.8)days (4-13 days). The average follow-up period was (25.5±16.9) months (2-60 months). During the follow-up period, 18 children had no persistent respiratory symptoms, and 4 children had only slight respiratory symptoms.Conclusion:Kommerell's diverticulum can also be combined with double aortic arch. The operation method is to separate the aortic arch and ligament at the atresia end and resect the diverticulum at the same time. It has a good early prognosis and may eliminate the residual symptoms and late complications.

Objective:To investigate the role of blood ammonia in the evaluation of the prognosis of septic patients in the emergency department and to compare its value with mortality in emergency department sepsis (MEDS) score.Methods:A retrospective clinical study was conducted to septic patients who were diagnosed in the Emergency Department of West China Hospital of Sichuan University from June 2017 to May 2018, and met the diagnostic criteria established by the diagnostic criteria of the American College of Chest Physicians/Society of Critical Care Medicine in 2001. The subjects who had other diseases that affected blood ammonia level and were lost to follow-up were excluded. MEDS scores were collected, and the survival status of patients was followed up by telephone. The independent samples t test was used to compare the differences between the two groups, receiver operating characteristic (ROC) curve was used to assess the accuracy of the prediction of sepsis mortality, and the logistic regression model was used to explore the value of the combined use of blood ammonia and MEDS score.Results:Eighty subjects were finally included in the study and divided into the 1-week survival group ( n=52), 1-week death group ( n=28); 4-week survival group ( n=37), 4-week death group ( n=43); 12-week survival group ( n=33), 12-week death group ( n=47); 1-year survival group ( n=32), and 1-year death group ( n=48). There was no statistical difference in the demographic characteristics of subjects between the groups. The average blood ammonia level of all the subjects who died was higher than that of the patients who survived in the same period [(116.57 ± 85.33) μmol/L vs (77.63 ± 35.82) μmol/L, (108.53 ± 73.00) μmol/L vs (71.19 ± 32.53) μmol/L, (106.74 ± 71.59) μmol/L vs (69.21 ± 28.84) μmol/L, (105.77 ± 71.14) μmol/L vs (69.50 ± 29.25) μmol/L, P<0.05]. Based on death after one week, four weeks, twelve weeks and one year, the area under ROC curve (AUC) of blood ammonia was 0.668 (95% CI: 0.542-0.793, P=0.014), 0.706 (95% CI: 0.593-0.819, P=0.002), 0.705 (95% CI: 0.592-0.818, P=0.002), and 0.697 (95% CI: 0.582-0.811, P=0.003), respectively. Compared with the use of blood ammonia, lactic acid or MEDS score alone, the combined use of blood ammonia and MEDS score increased the accuracy of prognosis evaluation in sepstic patients ( P<0.05). Conclusions:Blood ammonia has a high value in predicting the short-term and 1-year prognosis of septic patients in the emergency department. The combined use of blood ammonia and MEDS score can further improve its predictive value.

Objective:To investigate the morphological characteristics and operative methods of mixed total anomalous pulmonary venous connection (TAPVC), and to analyze the risk factors of postoperative death.Methods:From January 2011 to January 2019, 17 cases of mixed TAPVC were operated in Department of Cardiovascular Surgery, Beijing Children′s Hospital, Capital Medical University, with 10 males and 7 females.The average age was (4.4±3.8) months (1-15 months) and the average body mass was (5.6±1.7) kg (3.5-10.0 kg), including 1 case of ventricular septal defect, 17 cases of atrial septal defect and 15 cases of ductus arteriosus.Preoperative pulmonary vein stenosis was discovered in 4 cases and severe pulmonary hypertension was in 10 cases.A total of 5 cases needed ventilator support before operation, and 2 cases needed emergency operation.The diagnosis was confirmed by color Doppler ultrasound and CT before operation.There were 2 cases of type Ⅰ (type 2+ 2), 13 cases of type Ⅱ (type 3+ 1), and 2 cases of type Ⅲ (anatomic variant).Results:All the patients were treated through operation.The principle of operation was to correct all pulmonary veins to the left atrium.The cardiopulmonary bypass time was (182.3±122.8) min, the aortic occlusion time was (84.3±15.9) min, the postoperative ventilator support time was (92.9±70.0) h, and the monitoring room time was (6.9±4.9) d. In this group, 3 cases died in hospital (17.6%) and 1 case died out of hospital (5.9%).Conclusions:The mortality of mixed TAPVC type Ⅲ was high, while preoperative pulmonary vein stenosis, severe pulmonary hypertension and the combination of sub-cardiac type were the important risk factors of death.The operation mode depends on the anatomic drainage mode, so individualized operation is recommended.

Objective: To investigate the clinical features and improve the diagnosis and treatment of anomalous origin of the left coronary artery from the right coronary sinus with an interarterial course (ALCA-R-IAC) between the ascending aorta and main pulmonary artery in children. Methods: A retrospective analysis of the clinical manifestation, laboratory test, radiological feature, treatment and prognosis were conducted in four female children presented with ALCA-R-IAC in Beijing Children′s Hospital from November 2015 to June 2018. Results: The four girls with onset age of 7.5-14.7 years were diagnosed with ALCA-R-IAC by CT coronary angiography (CTCA). Four children presented with exercise-induced syncope and clinical manifestations of acute myocardial infarction including 3 patients with acute left heart failure, 1 cardiogenic shock and 1 cardiac arrest. Nervous system involvement was found in one patient. Troponin I increased significantly to 20.65-50.00 μg/L in the four patients. Electrocardiogram (ECG) developed signs of left main coronary artery involvement. Echocardiography revealed reduced left ventricular ejection fraction (LVEF) of 25%-45% in three children and suspected anomalous origin of the left coronary artery in one child. CTCA showed an anomalous left coronary artery originating from the right coronary sinus, which had an interarterial course between the aorta and pulmonary artery leading to a slim left main coronary trunk. Two children underwent unroofing procedure and the other two children in whom physical activities were restricted received conservative managements. During a regular follow-up period of 12-43 months, all the children survived without recurrent symptoms and had good prognosis. Conclusions ALCA-R-IAC can present as exercise-related syncope and acute myocardial infarction, even sudden death in children and adolescents. CTCA is helpful to clarify the early diagnosis of ALCA-R-IAC. Surgical intervention is the main treatment for ALCA-R-IAC and strenuous physical activities should be avoided.

Objective:To study the classification of persistent fifth aortic arch (PFAA) and the value of echocardiography in the diagnosis of PFAA.Methods:A total of 16 cases (male 6, female 10, at ages from 7 days to 4 years and 2 months old, the median age was 3 months) diagnosed with PFAA in Beijing Children′s Hospital Affiliated to Capital Medical University from January 2013 to June 2019 were studied retrospectively. The diagnosis standard, differential methods and misdiagnosed analysis of different subtypes of PFAA by echocardiography were summarized and analyzed.Results:The 16 cases included 1 case of type A1 double lumen aortic arch, 8 cases of type A2 single-lumen aortic arch, 3 cases of type B1 with pulmonary atresia and 4 cases of type B3 pulmonary artery branch arising from the distal end of ascending aorta. Only one patient of double lumen aortic arch missed diagnosis by echocardiography, and the rest were accurately diagnosed by echocardiography. CTA was performed in 13 cases, including 9 cases of type A, 1 case of type B1 and 3 cases of type B3, which confirmed the echocardiography diagnosis. Seven cases of Type A2 were operated.Conclusions:PFAA is a rare and complicated aortic arch malformation, which is divided into four major classification and multiple subtypes. Echocardiography can diagnose the PFAA and its classification, it is of great clinical significance for the early diagnosis, treatment and prognosis of children.

Objective: To investigate the clinical efficacy of laparoscopic subtotal colonic bypass plus colostomy with antiperistaltic cecoproctostomy (SCBCAC) in the treatment of senile slow transit constipation. Methods: A retrospective cohort study was performed. Clinical data of 30 colonic slow transit constipation patients aged ≥70 years old undergoing laparoscopic SCBCAC from July 2012 to October 2016 (bypass plus colostomy group), and 28 patients undergoing laparoscopic subtotal colonic bypass with antiperistaltic cecoproctostomy (SCBAC) from February 2009 to June 2012 (bypass group) at our institute were collected. Efficacy was compared between the two procedures. Inclusion criteria: (1) meeting the Rome III diagnosis criteria for constipation; (2) confirmed diagnosis of slow transit constipation; (3) age ≥ 70 years old; (4) receiving non-surgical treatment for more than 5 years, and Wexner constipation score > 15; (5) follow-up for more than 2 years. Those with psychiatric symptoms or previous psychiatric history, obvious signs of outlet obstructive constipation, organic diseases of the colon and life-threatening cardiovascular diseases or cancer were excluded. In the bypass plus colostomy group, laparoscopy was performed via five trocars. The ileocecal junction and the ascending colon were mobilized and the ileocecal junction was pulled down to the pelvic inlet. The ascending colon was transected and the appendix was excised. The lateral peritoneum of the sigmoid colon and the rectal mesentery were dissected and the upper rectum was transected. The avil of a circular stapler was placed in the bottom of the cecum. The shaft of the stapler was placed in the rectum via the anal canal to complete end-to-side anastomosis (end rectum to lateral cecum). The end of the rectal-sigmoid colon was used for colostomy via an extraperitoneal approach to complete the operation. The following efficacy indexes were collected before surgery and 3, 6, 12, and 24 months after surgery: the number of daily bowel movements, the Wexner incontinence scale (WIS, 0-20, the lower the better), the Wexner constipation scale (WCS, 0-30, the lower the better), the gastrointestinal quality of life index (GIQLI, 0-144, the higher score, the better), abdominal pain intensity indicated by the numerical rating scale (NRS, 0-10, the lower score, the better), and the abdominal bloating score (ABS, 0-4, the lower score, the better). The complications defined as Clavien-Dindo class II or above were observed and recorded. Results: No significant differences in preoperative WCS, WIS, GIQLI, NRS, and ABS were observed between bypass plus colostomy group and bypass group (all P>0.05). All the patients successfully underwent laparoscopic surgery and no patient in either group experienced postoperative fecal incontinence. WCS and GIQLI were significantly improved (all P<0.001) at 3, 6, 12, and 24 months after surgery in both groups. At 12 months after surgery, the number of bowel movements was significantly less in bypass plus colostomy group than that in bypass group [(2.4±0.7) times vs. (3.4±1.2) times, t=4.048, P<0.001]. At 3, 6, 12 and 24 months after surgery, the improvement of GIQLI in bypass plus colostomy group was significantly better than that in bypass group (all P<0.001). At 24 months after surgery, GIQLI in bypass plus colostomy group and bypass group was 122.3±5.3 and 92.8±16.6, respectively, with a significant difference (t=9.276, P<0.001). At 12 and 24 months after surgery, NRS in bypass plus colostomy group was significantly better than that in bypass group (both P<0.001). At 24 months after surgery, NRS in bypass plus colostomy group was 0.9±0.7, while that in bypass group was 3.7±2.7. There was a significant difference between two groups (t=5.585, P<0.001). At 6, 12 and 24 months after surgery, the improvement of ABS in bypass plus colostomy group was also significantly better than that in bypass group. At 24 months after surgery, ABS in bypass plus colostomy group was 0.6±0.6, while that in bypass group was 2.5±1.0, with a significant difference between two groups (t=8.797, P<0.001). At 1 year after surgery, barium enema examination was performed in all the patients of both groups. The barium emptying time was (21.2±3.8) hours and (95.8±86.2) hours in bypass plus colostomy group and bypass group respectively. The former group was significantly better than the latter group (t=4.740, P<0.001). Conclusions Laparoscopic SCBCAC is an effective and safe procedure for the treatment of senile slow transit constipation and can significantly improve prognosis. Its clinical efficacy is better than laparoscopic SCBAC.

Objective To evaluate the effect of laparoscopic rectopexy with Douglas pouch repair combined with procedure for prolapse and hemorrhoids (PPH) based on pelvic anatomy for rectal internal mucosal prolapse.Methods From Mar 2009 to Sep 2011.37 patients (group A) received taparoscopic rectopexy with Douglas pouch repair based on pelvic anatomy,and group B (n =41) received laparoscopic rectopexy with Douglas pouch repair combined with PPH.Constipation level,degree of internal prolapse,relapse and postoperative complications were assessed in 5 years after operation.Results 5 years after operation,the relief of constipation and the improvement of internal prolapse in group B were better than in group A [(-0.4 ± 0.9) cm vs.(-1.0 ± 1.1) cm,t =2.370,P =0.020].The recurrence rate in group B was statistically lower than that in group A (10％ vs.30％,x2 =4.995,P =0.025).Grade Ⅰ to Grade Ⅲ complications between the two groups was not statistically different (11％ vs.12％,x2 =0.037,P =0.848).Conclusions The effect of laparoscopic rectopexy with Douglas pouch repair combined with PPH based on pelvic anatomy for rectal internal mucosal prolapse was superior to laparoscopic rectopexy with Douglas pouch repair.
