[Study on thirty patients with slow-transmission constipation treated by acupuncture and moxibustion].

OBJECTIVE: To assess the therapeutic effects and acting specialty of acupuncture and moxibustion for treatment of slow-transmission constipation (STC). METHODS: A clinical pathway was created and Patient-Reported Outcomes (PROs) method was taken for efficacy evaluation dominantly. Acupuncture and moxibustion were applied to 30 STC patients on two groups of acupoints in alternation, with acupoints of Tianshu (ST25), Daheng (SP15), Fujie (SP14), Qihai (RN6), Guanyuan (RN4), Zusanli (ST36), and Shangjuxu (ST37) as group 1; Dachangshu (BL25), Shenshu (BL23), Baliao (BL31, BL32, BL33, BL34), and Sishencong (Ex-HN1) as group 2. Deep needling was applied on acupoints of abdominal and back region and moxibustion was put on Sishencong, 20 times as one course. The therapeutic effect was assessed based on the Patient Assessment of Constipation Quality of Life Questionnaire (PAC-QOL) method by comparing the Bristol scoring on quality of stool, awareness and frequency of defecation, degree of abdominal fullness sensation, and patients' quality of life (QOL) at different time points, i.e., pre-treatment, after 1, 2 and 3 weeks of treatment. RESULTS: Compared with the condition of pre-treatment, after 1, 2 and 3 weeks of treatment, cases using irritant laxative or glycerin enema reduced, with quality of stool normalized, scores for awareness and frequency of defecation increased, and abdominal fullness sensation lessened (all P < 0.01); both the total score and scores on the 4 domains of QOL (malaise, psychosocial complaint, anxiety and interest related to constipation, and satisfaction) were obviously reduced. No adverse event occurred during the treatment course. Therapeutic effectiveness assessment at the end of treatment showed that 13 patients were cured, 9 improved and 8 treated in vain; the corresponding cases assessed at 1 month after treatment were 10, 7, 13; and those at 3 months after were 7, 8, 15, respectively. CONCLUSION: Establishing a clinical pathway is helpful to patients in their continuous diagnosis and treatment. Using PROs method to evaluate the therapeutic effect could clearly reveal the superiority of acupuncture and moxibustion in improving symptoms and QOL in patients of STC.

Role of three-dimensional endoanal ultrasound in assessing the anal sphincter morphology of female patients with chronic proctalgia.

AIM: To assess the role of three-dimensional endoanal ultrasound (3D-EAUS) for morphological assessment of the anal sphincter of female patients with chronic proctalgia (CP). METHODS: In this unmatched case control study, 30 consecutive female patients with CP and 25 normal women (control group) were enrolled. 3D-EAUS was performed in all subjects. Thickness and length of internal anal sphincter (IAS), thickness of puborectalis muscle (PR), length of the external anal sphincter (EAS) plus PR, and puborectalis angle were measured and compared between the two groups. RESULTS: Patients with CP had significantly shorter IAS length and greater PR thickness, as compared to those in normal individuals (26.28 ± 3.59 mm vs 28.87 ± 4.84 mm, P < 0.05 and 9.67 ± 1.57 mm vs 8.85 ± 0.97 mm, P < 0.05, respectively). No significant between-group differences were observed with respect to IAS thickness and the EAS plus PR length (P > 0.05). Puborectalis angle in the CP group was significantly decreased, both in resting (88.23° ± 1.81° vs 89.94° ± 2.07° in control group, P < 0.05) and straining (88.47° ± 3.32° vs 90.72° ± 1.87° in control group, P < 0.05) phases, which suggest the presence of paradoxical contraction of PR in patients with CP. In the CP group, no significant difference in puborectalis angle was observed between the resting and straining phases (88.23° ± 1.81° vs 88.47° ± 3.32° respectively, P > 0.05). CONCLUSION: The association of greater PR thickness and paradoxical contraction of PR with CP suggest their potential value as markers of CP.

[Research on the Angle and Effective Depth of Deep Acupuncture at Baliao Points by Three-dimensional Reconstruction of Computed Tomography].

OBJECTIVE: To explore the needle insertion parameters of deep acupuncture at Baliao points for clinic and teaching. METHODS: A retrospective analysis of 100 cases of prone pelvic CT from January to June 2016 in Nanjing Hospital was carried out. The 3 D images were scanned with continuous 5 mm slice thickness. The optimum needle angle is defined as the angle of the needle along the central axis of sacral anterior and posterior hole, and the angle between the needle body and the skin surface and the center line of the body was observed. The effect needle depth is defined as the thickness of the sacral back soft tissue plus 1/2 sacral depth, to observe the best needle angle of deep acupuncture parameters of Baliao points. RESULTS: For deep acupuncture at Baliao, the oblique thorn method should be used with the needle-point toward the inner bottom. The best insertion angle between needle body and skin surface is: Shangliao(BL 31) (61.04±12.15)°ï¼Œ Ciliao(BL 32) (57.57±10.01)°ï¼Œ Zhongliao(BL 33) (58.25±8.69)°ï¼Œ Xialiao(BL 34) (54.39±10.94)°. The optimum angle of insertion between the needle body and the posterior midline of the human body is: BL 31 (24.54±6.21)°ï¼Œ BL 32 (18.58±7.76)°ï¼Œ BL 33 (17.36±7.90)°ï¼Œ BL 34 (30.73±9.45)°. The effective insertion depth show a decreasing trend: BL 31 (58.16±12.43) mm, BL 32 (44.57±11.55) mm, BL 33 (33.96±10.74) mm, BL 34 (31.13±10.94) mm. The effective depth is positively correlated with BMI, and has no correlation with gender and weight. CONCLUSIONS: The study of the parameters of needle insertion should be taken into account both clinical efficacy and safety, and CT three-dimensional reconstruction can accurately, rationally and scientifically perform acupoint anatomical measurements.

[Variation of Locations of Baliao Acupoints in 290 Volunteer Subjects Analyzed by Using Computed Tomography-aided Three-dimensional Reconstruction Technique].

OBJECTIVE: To observe the variation of sacral vertebrates and foramen involving the bilateral Shangliao (BL 31), Ciliao (BL 32), Zhongliao (BL 33) and Xialiao (BL 34, Baliao acupoints), so as to provide an anatomic basis of acupoint needling in clinical practice. METHODS: A total of 290 patients[161 men and 129 women, mean age and standard devia-tion, (63.6±13.3)years old and (59.5±13.3) years old, respectively] with intact pelvic structure were recruited in the present study. Computed tomography (CT) scans of intact pelves were taken using a SOMATOM Definition AS 128 and the acquired signals were imported into Siemens Syngo Inspace platform for 3 D reconstruction, followed by identification, classification and analysis of the variation of sacral foramen (Baliao acupoint). RESULTS: The total variation rate of posterior sacral foramen (Baliao acupoint) was 20.34%(59/290). The detected three types of variation were sacral vertebrae number variation (4 sacral vertebraes, 6 sacral vertebraes), fusion variant (lumbosacral fusion, sacrococcygeal fusion, lumbosacral & sacrococcygeal fusion, and lumbosacral fusion & S 4 variation) and mixed type. CONCLUSIONS: Variations of sacral vertebrae including the number and fusion exist in the human body, suggesting an increase of the difficulty of acupoint needling. Since posterior iliac spine does not change generally, it is recommended to be used as a reference point for locating the Baliao acupoint.

Effect of modified Sinisan on anorectal manometry of the constipation predominant type of irritable bowel syndrome.

OBJECTIVE: To explore the mechanism in patients with irritable bowel syndrome (IBS) of the constipation predominant type and observe the therapeutic effects of Sinisan (SNS). METHODS: Forty-seven IBS patients with the constipation predominant type were randomly divided into the treated group (n = 24) and the control group (n = 23). Another group of 22 healthy subjects was set up for healthy control. The treated group was treated with modified SNS, and the control group was treated with Cisapride, the therapeutic course for both groups was 8 weeks. The changes of symptom scoring and anorectal manometry (the anorectal resting pressure, anal tract systolic pressure, anal tract diastolic pressure, rectal threshold feeling, maximal tolerance volume of rectum, and rectum compliance) of these two groups were recorded respectively and compared with each other. RESULTS: Compared with the healthy control group, the rectal threshold feeling, maximal tolerance volume of rectum and rectal compliance of the treated groups got reduced significantly before treatment (P < 0.05). After treatment, the symptom scoring, rectal threshold feeling and maximal tolerance volume of rectum were improved in both groups (P < 0.05), and the improvement of the treated group was more significant than that of the control group (P < 0.01). The total effective rate and recurrence rate of the treated group were superior to those of the control group significantly (P < 0.05, P < 0.01). CONCLUSION: SNS has good effect on IBS of the constipation predominant type.

[Development of Researches on the Underlying Mechanism of Acupuncture Stimulation of Baliao-points for Improving Outlet Obstruction Constipation].

Outlet obstruction constipation (OOC) is a common clinical problem affecting many people's daily life quality nowadays. Acupuncture therapy is effective in easing OOC to reduce patients' sufferings by stimulation of Baliao-points i. e., bilateral Shangliao (BL 31), Ciliao (BL 32), Zhongliao (BL 33) and Xialiao (BL 34), which has been confirmed repeatedly in clinical practice. In the present paper, the authors reviewed development of studies on the underlying mechanisms of acupuncture stimulation of Baliao-points for OOC from: 1) lowering the sensitivity of intraganglionic laminar nerve endings (rIGLEs) to rectal mechanical distension during defecation, 2) raising the level of circulating cholecystokinin (CCK) to improve the sensory threshold of the rectum, 3) lowering the excitability of γ-motor neurons in the spinal anterior horns controlling the slow contraction of the rectal sphincter muscle, 4) inhibiting the excitability of sympathetic output from the spinal lateral horns, 5) easing the tonic contraction of the pelvic muscles to reduce the release of 5-hydroxy tryptamine (5-HT), histamine, and other related chemical mediators due to local ischemia. Moreover, further study on the mechanism of acupuncture stimulation of Baliao-points underlying improving OOC may help up find more specific and effective therapeutic targets and provide more reliable experimental foundation and theoretical basis.

[Observation on effect characteristics of electroacupuncture for different types of functional constipation].

OBJECTIVE: To explore the differences of electroacupuncture (EA) on onset time and symptom improvement for treatment of different types of functional constipation. METHODS: Thirty-eight cases of constipation were selected, including 9 cases of constipation-predominant irritable bowel syndrome (IBS-C), 10 cases of slow transit constipation (STC), 10 cases of pelvic floor dyssynergia (PFD) and 9 cases of inadequate defecatory propulsion (IDP). The electroacupuncture was applied at Tianshu (ST 25), Fujie (SP 14), Shenshu (BL 23), Dachangshu (BL 25) and so on in abdominal and lumbosacral area, 5 times per week, 10 times as a treatment course. The onset time, score of clinical symptoms of constipation and improvement of every symptom in each group were compared. RESULTS: (1) The onset time was (1.78 +/- 0.83) days in IBS-C type, (3.11 +/- 1.90) days in IDP type, (4.10 +/- 1.85) days in STC type and (4.30 +/- 2.00) days in PFD type, indicating statistical differences between IBS-C type and STC type, IBS-C type and PFD type (both P < 0.05). (2) Compared before the treatment, the total scores of symptoms on the onset day in each group were all improved (P < 0.05, P < 0.01), and score of IBS-C type was superior to the rest 3 types (P < 0.05, P < 0.01). (3) EA improved desire to defecate or frequency of defecation in each type (P < 0.05, P < 0.01), in which both were improved in STC type and PFD type, and the improvement of defecation frequency was more significant in STC type (P < 0.01). EA relieved unsmooth defecation or pendant-expansion feeling in each type (all P < 0.05), in which both were improved in IBS-C type (both P < 0.05). EA relieved abdominal distension and pain in IBS-C type, STC type and PFD type (all P < 0.05), while its effects were not obvious on defecation difficulty, defecation time and defecation texture (all P > 0.05). CONCLUSION: The electroacupuncture for treatment of 4 types of constipation is characterized by rapid onset; the improved symptoms are not identical in the electroacupuncture treatment plan for each type of defecation; the main improvement of symptoms are lied on desire to defecate and frequency of defecation, unsmooth defecation or pendant-expansion feeling and abdominal distension and pain. Meanwhile the improvements of defecation texture, defecation difficulty and defecation time were not signi-ficant.

[Dynamic three-dimensional ultrasound in the diagnosis of pelvic floor dyssynergia].

OBJECTIVE: To explore the feasibility of dynamic three-dimensional ultrasound measurement in the diagnosis of pelvic floor dyssynergia(PFD). METHODS: Thirty female patients with PFD received dynamic three-dimensional ultrasound. The differences in angle α measured by transperineal three-dimensional ultrasound, and angle ß, angle γ, and H line as measured by transanorectal three-dimensional ultrasound were compared between resting state and Valsalva maneuver. In addition, the detective rate of PFD by different parameters was analyzed. RESULTS: In 30 patients, rectocele was found in 13 cases(43.3%), rectal internal mucous intussusception in 14 cases(46.7%), uterine prolapse in 11 cases(36.7%), and bladder prolapse in 1 case(3.3%). Compared with the resting state, α, ß and H decreased obviously, but γ increased apparently in Valsalva maneuver, and differences of these parameters were statistically significant(all P<0.01). Detective rates of PFD for parameters of α, ß, γ and H were 93.3%(28/30), 96.7%(29/30), 96.7%(29/30) and 86.7%(26/30), respectively. CONCLUSION: Measurements of α, ß, γ and H can provide feasible indicators for clinical diagnosis of PFD.

[Dynamic three-dimensional ultrasound study on levator ani muscle fissures for female pelvic floor relaxation syndrome].

OBJECTIVE: To explore the value of dynamic three-dimensional ultrasound in detecting the levator ani muscle fissures morphological changes of female pelvic floor relaxation syndrome after biofeedback and acupuncture treatments. METHODS: Forty female constipation patients with pelvic floor relaxation syndrome were screened from the Constipation Designed Disease Clinic in our hospital between October 2011 and September 2012. Cleveland Constipation Score (CCS) scale was used. Anteroposterior and transverse diameters of the levator ani muscle fissures were measured by dynamic three-dimensional ultrasound in Valsalva maneuver. After a course (10 days) of biofeedback and acupuncture treatments, CCS scale was filled, and dynamic three-dimensional ultrasound was performed in Valsalva maneuver as well. Associated data before and after treatment were compared. RESULTS: Twenty-five patients completed the trial. As compared to pre-treatment, the longitudinal axes of levator ani muscle fissure [(4.89±0.89) cm vs. (5.13±0.82) cm, P<0.01], the horizontal axes of the levator ani muscle fissure [(4.62±0.75) cm vs. (4.86±0.74) cm, P<0.01], and the area of the levator ani muscle fissure [(18.16±6.42) cm(2) vs. (19.92±6.33) cm(2), P<0.01] decreased significantly after treatment, while CCS scale (9.52±2.50 vs. 15.80±3.42, P<0.01) declined significantly as well. CONCLUSIONS: The dynamic three-dimensional ultrasound is an effective, simple and non-invasive method for the determination of levator ani muscle fissure in female patients with pelvic floor relaxation syndrome.

[Study on the measurement and locating of Baliao points (eight sacral foramina)].

OBJECTIVE: To seek the problems of position, measuring and locating methods of Baliao points (posterior sacral foramina) in modern researches. METHODS: Using Baliao (eight sacral foramina), Shangliao(BL 31), Ciliao(BL 32), Zhongliao(BL 33), Xialiao(BL 34), Dihoukong (posterior sacral foramina), Dikong (sacral foramina) and Digu(sacrum) as the key words, literature in the database of the CNKI from 1957 to 2012 were re trieved and analyzed. RESULTS: Problems were found in the past researches including limited numbers of relative literature, disunity of the measurement targets, complicated terms of indices, disunity of the starting and ending point of measurement, unclear weight of indices, deviation of results, lacking of combination with clinical practice and variety of locating methods. CONCLUSION: Position of Baliao points (eight sacral foramina) are clear. However, the locating methods are blurred and vary a lot. Study on living body has more significance for measurement and researches. Factors of gender, body weight, height and childbearing should also be taken into consideration. Therefore, it is necessary to find a more accurate and easier way of locating.

[A multi-center, randomized, double-blind, placebo-controlled trial of glyceryl trinitrate ointment in the treatment of anal fissure].

OBJECTIVE: To evaluate the clinical efficacy and safety of glyceryl trinitrate (GTN) ointment in the treatment of anal fissure. METHODS: In this multi-center, randomized, double-blind and placebo-controlled trial, 240 chronic anal fissure patients from 7 clinical centers were randomized to receive eight-week treatment with GTN ointment (treatment group) or vaseline ointment (control group) respectively. Healing rate, visual analogue score (VAS), maximum anal resting pressure (MARP) and adverse reactions were recorded and compared. RESULTS: A total of 221 patients (92.1%) finished the trial, including 114 patients in treatment group (95.0%, 114/120) and 107 in control group (89.2%, 107/120). At the endpoint of treatment (56 d), 90 patients in treatment group (78.9%, 90/114) healed completely compared to 31 patients in control group (29.0%, 31/107), and decrease rates of VAS in the two groups were (94.8±15.7)% and (61.2±35.7)% respectively, both differences were statistically significant (P<0.01). MARP after first administration was (20.2±18.5) mm Hg in treatment group (n=12) and (7.1±14.7) mm Hg in control group (n=6), which was not significantly different (P=0.152). Adverse reaction incidence was higher in treatment group (42.1% vs. 9.3%, P<0.05), while these adverse reactions were mainly headache and fullness in head, which were self-limiting. CONCLUSION: GTN ointment can effectively promote healing and relieve pain in anal fissure with safety and tolerance.

[Clinical study on acupuncture for treatment of chronic functional constipation].

OBJECTIVE: To discuss the effect of acupuncture for treatment of chronic functional constipation (CFC). METHODS: Ninety cases were treated with acupuncture. The following two groups of acupoints were used alternatively once every other day. The acupoints in the first group were Tianshu (ST 25), Qihai (CV 6), Shangjuxu (ST 37) etc., and Zhongliao (BL 33), Xialiao (BL 34), Dachangshu (BL 25) etc. in the second group, electroacupuncture was used at Zhongliao (BL 33), Xialiao (BL 34), Tianshu (ST 25) and Shangjuxu (ST 37), once a day, 10 times constituting one course. The defecation frequency, difficulty degree of defecation, defecation time, endless sensation of defecation, stool quality and awareness of defecation were observed and the Patient Assessment of Constipation Quality of Life (PAC-QOL) was evaluated by constipation patients' diaries. RESULTS: The scores of defecation frequency, difficulty degree of defecation, defecation time, endless sensation of defecation, stool quality, awareness of defecation and PAC-QOL were obviously improved after treatment (all P < 0.01). The total effective rate was 67.7% (61/90). The effect of acupuncture for chronic functional constipation in different dynamic mechanism was different. The effect of slow transit constipation (STC) was better than that of spastic pelvic floor syndrome (SPFS) (P < 0.05), and the effect of constipation caused by irritable bowel syndrome (IBS-C) was better than that of SPFS and relaxant pelvic floor syndrome (RPFS) (both P < 0.05). Fifty-two cases were effectively followed up. Three cases were cured, 6 cases were remarkably effective, 23 cases were effective and 20 cases were ineffective after 1 month of treatment. Three cases were cured, 5 cases were remarkably effective, 16 cases were effective and 28 cases were ineffective after 3 months. CONCLUSION: The effect of acupuncture for CFC with exact etiology, disease location and classification diagnosis is definite, but different dynamic mechanism has different effect. The treatment programs for SPFS and RPFS need to be optimized to improve the therapeutic effect.

[Application of magnetic resonance imaging in the diagnosis of complex anal fistula].

OBJECTIVE: To evaluate the value of magnetic resonance imaging (MRI) in the diagnosis of complex anal fistula. METHODS: The preoperative digital examination and MRI with the phased-array coil were implemented for 28 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: Twenty-five patients were diagnosed as complex anal fistula, 1 presacral cyst and 2 chronic anorectal fistula combined with perianal mucinous adenocarcinoma. All the patients were correctly diagnosed by MRI,while the patients with presacral cyst and perianal mucinous adenocarcinoma could not be diagnosed correctly by digital examination. According to the Parks classification, 3 patients were suffered from trans-sphincteric fistula, 10 intersphincteric, 5 supra- sphincteric and 7 extra-sphincteric. The diagnosis rates of the internal opening with digital examination and MRI were 48% and 84%, the rates of the primary tract were 76% and 100%, and the rates of the secondary extensions were 57.9% and 94.7% respectively. The differences in detection of internal opening, primary tract and secondary extensions between MRI and digital examination were significant (P<0.01). CONCLUSION: MRI with the phased-array coil can correctly orient the internal opening and direction of the complex anal fistula, and find the relationship between anorectal sphincters and the complex fistula.

[Detection of microsatellite instability in colorectal cancer by fluorescence multiplex polymerase chain reaction and its clinical value].

OBJECTIVE: To detect microsatellite instability(MSI) in colorectal cancer by fluorescence multiplex polymerase chain reaction(FM-PCR) and explore its clinical value. METHODS: MSI of 110 colorectal cancer patients undergone surgical resection in our department from 2004 to 2005 were examined by FM-PCR, and the pathological characteristics were compared between MSI and microsatellite stable (MSS) colorectal cancer patients. RESULTS: Among 110 cases, the male were 66 and the female were 44. Mean age was 60.8 (26-94) yrs. All 5 microsatellite markers were amplified. Out of them, 10 cases (8.1%) were MSI-H, 13 cases (11.8%) were MSI-L and 87 cases (79.1%) were MSS. Instability of BAT-26 was found in 9 cases (8.2%), BAT-25 was in 11 cases (10.0%), D2S123 was in 11 cases (10.0%), D5S346 was in 6 cases (8.2%) and D17S250 was in 8 cases (7.3%). Age between MSI and MSS colorectal cancer patients was significant and other pathological characteristics were not significant. CONCLUSIONS: FM-PCR is a clinically stable method for MSI detection in colorectal cancer patients. There are no significant differences between MSI and MSS pathological characteristics of colorectal cancer patients.

[Diagnosis and treatment of pediatric anismus].

OBJECTIVE: To explore the diagnosis and treatment methods of pediatric anismus. METHODS: Twenty-nine patients with idiopathic chronic constipation, diagnosed with anismus by colon barium contrast and anorectal manometry from Nov. 2001 to Nov. 2004 in our hospital, were investigated retrospectively. RESULTS: This group consisted of 13 men and 16 women whose mean age was (6.7+/-4.0) years. Hirschsprung diseases were excluded from the patients by colon barium contrast and rectoanal inhibitory reflex (RAIR) examination. Normal RAIR (5-10 ml elicited) was showed on 21 cases while weakened RAIR (15-30 ml elicited) was showed on 8 cases. After the diagnosis, the patients were treated by toilet training, diet regulation and laxative for 1-2 months. 4 cases were recovered, 5 cases were improved and 20 cases were relied on glycerin suppository. Four cases, relied on glycerin suppository, underwent Lynn procedure and had good results after 5-24 months follow-up. Two cases were re-examined by anorectal manometry 3 and 6 months after surgery, the resting pressure and the high pressure zone (HPZ) decreased, but the simulation defecation reflex was still abnormal. CONCLUSIONS: The diagnosis of pediatric anismus relies on history of constipation, combined with anorectal manometry and colon barium contrast. Lynn procedure could be chosen for the patients unsatisfied in toilet training and other non-operative treatment.

[Diagnosis and surgical management of adult Hirschsprung disease].

OBJECTIVE: To investigate the diagnosis and surgical treatment of adult Hirschsprung disease (AHD). METHODS: Clinical data of 10 patients with AHD undergoing operation from May 1985 to May 2005 were analyzed retrospectively. RESULTS: There were 7 males and 3 females with an age ranged from 14 to 40 years. All the cases had constipation, and were diagnosed by barium enema. Aganglionosis was located in distal sigmoid and rectum in 2 cases, in rectum in 7 cases, unknown in one case. Colostomy was performed in one, Ikeda s operation in 6, Rehbein operation in two,modified Swenson operation in one. After radical operation,7 patients had excellent continence function, one had good function, one had poor function. CONCLUSIONS: The diagnosis of adult HD mainly depends on the history of constipation, barium enema and manometry examination. The pull-through procedures are effective surgical treatments for adult HD. The operation type should be selected individually.
