This paper introduces Professor HUANG Jinchang's experience in treating low anterior resection syndrome (LARS) of rectal cancer. Based on the clinical experience in treating fecal incontinence after rectal cancer surgery, Professor HUANG Jinchang proposes that the primary pathogenesis of LARS is spleen-kidney yang deficiency with internal obstruction of damp turbidity. The treatment approach should focus on strengthening the spleen, warming the kidney, and eliminating turbidity. The Baliao acupoints are specifically selected to eliminate turbidity, promote yang , facilitate the qi flow of the viscera, and regulate the opening and closing of the anus. Emphasis is placed on deep needling at the Baliao acupoints, with flexible acupoint selection based on accompanying symptoms. Additionally, moxibustion and bloodletting cupping are used to restore regular bowel movements and improve the quality of life for patients who have undergone anus-preserving surgery for rectal cancer.

Colonic and anorectal manometry includes anorectal manometry and colonic manometry. Anorectal manometry is a common method to evaluate anorectal function, which can objectively reflect the pathological and physiological abnormalities of outlet obstructive constipation and fecal incontinence, as well as the impact of anorectal surgery on continence. Colonic manometry is a new type of colon motility detection method developed in recent years. It can record the peristalsis and contraction of the whole colon through a pressure measuring catheter, which helps physicians further evaluate various colonic diseases. However, various factors such as testing equipment, operating standards, and evaluation parameters are difficult to unify. There is no consensus on the operation and interpretation of colorectal anal pressure measurement. Under the guidance of the Anorectal Branch of Chinese Medical Doctor Association, in collaboration with Clinical Guidelines Committee, Anorectal Branch of Chinese Medical Doctor Association, Anorectal motility disorders Committee , Colorectal Surgeons Branch of Chinese Medical Doctor Association, Colonic Branch of China international exchange and promotive association for medical and healthcare, Tianjin Union Medical Center is leading the organization of domestic experts in this field. Based on searching relevant literature and combining clinical experience at home and abroad, after multiple discussions, the "Chinese expert consensus on colonic and anorectal manometry" has been prepared. This consensus discusses the indications, contraindications, pre examination management and technical procedures, treatment of complications, and interpretation of examination reports for colonic and anorectal manometry , aiming to guide the standardized clinical practice of colonic and anorectal manometry.

Intersphincteric resection (ISR) has been performed as an ultimate sphincter-sparing strategy in selected patients with low rectal cancer. Accumulating evidence suggests that ISR may be an interesting alternative to abdominoperineal resection to avoid a permanent stoma without compromising oncological outcomes. However, bowel dysfunction is a most common consequence of ISR not to be neglected. To date, limited clinical research has reported functional and quality of life outcomes according to patient-reported outcome measures. Also, data concerning management of low anterior resection syndrome are scarce due to lack of quality evidence. Therefore, this review provides an up-to-date summary of systematic assessment (including function, quality of life, manometry and morphology) and bowel rehabilitation for ISR patients. Postoperative anal function is often assessed by a combination of scales, including the Incontinence Assessment Scale, the Gastrointestinal Function Questionnaire, the Specific LARS Assessment Scale and the Faecal Diary. The condition-specific Quality of Life Scale is more appropriate for Quality-of-life measures in fecal incontinence after ISR. Patients' physiological function after ISR can be assessed using water- or high-resolution solid-state anorectal manometry. Anatomical and morphological changes can be assessed using defecography and 3D endorectal ultrasound. Electrical stimulation and biofeedback, pelvic floor exercises, rectal balloon training, transanal irrigation and sacral neuromodulation are all options for post-operative rehabilitation.

Fecal incontinence is one of the common diseases in the field of colorectal and anal surgery. Its etiology is complex, the treatment response is suboptimal, and there are controversies in clinical care. There is no consensus on the clinical practice of fecal incontinence in China currently. Launched by Anorectal Branch of Chinese Medical Doctor Association, Expert Committee on Anorectal Disease of Anorectal Branch of Chinese Medical Doctor Association, and Clinical Guidelines Committee of Anorectal Branch of Chinese Medical Doctor Association, and organized by the editorial board of Chinese Journal of Gastrointestinal Surgery, Chinese experts on this field were convened to write the Chinese expert consensus on clinical practice of fecal incontinence based on relevant references. After rounds of discussion, the final consensus combines the latest evidence and experts' clinical experience. This expert group suggested that a comprehensive assessment of fecal incontinence should be conducted before treatment, including medical history, relevant scales, physical examination and special examinations. Special examinations include anorectal endoscopy, anorectal manometry, transrectal ultrasound, magnetic resonance, rectal sensation and compliance, balloon ejection test, pelvic floor electromyography, defecography, colonoscopy and pudendal nerve terminal motor latency. Treatment methods include life style modification, medication, surgery, traditional Chinese medicine and other treatments. This consensus aims to standardize the algorithm of fecal incontinence management and improve therapeutic efficacy.

Advances in surgical techniques and treatment concept have allowed more patients with low rectal cancer to preserve sphincter without sacrificing survival benefit. However, postoperative dysfunctions such as fecal incontinence, frequency, urgency, and clustering often occur in patients with low rectal cancer. The main surgical procedures for low rectal cancer include low anterior rectum resection (LAR), intersphincteric resection (ISR), coloanal anastomosis (Parks) and so on. The incidence of major LARS after LAR is up to 84.6%. The postoperative function of ISR is even worse than LAR. Moreover, the greater the extent of resection ISR surgery, the worse the postoperative function. There are few studies on the function of Parks procedure. Current evidence suggests that the short-term function of Parks procedure is inferior to LAR, but function can gradually recovered over time. Colorectal surgeons have attempted to improve postoperative defecation by modifying bowel reconstructions. Current evidence suggests that J pouch or end-to-side anastomosis during LAR does not reduce the incidence of defecation disorders. Pouch reconstruction during ISR cannot reduce the incidence of severe LARS either. In general, the protection of postoperative defecation function in patients with low rectal cancer still has a long way to go.

PURPOSE: There is no established treatment of choice for low anterior resection syndrome (LARS). To evaluate the efficacy of biofeedback therapy for objective improvement of pelvic function in LARS, we performed the present study. METHODS: The primary endpoint was the change of Wexner score. Consenting patients between 20 and 80 years old with major LARS at least 2 months after sphincter preserving proctectomy for rectal cancer were enrolled. After recommendation of biofeedback therapy, patients who accept it were enrolled in the biofeedback group and patients who refuse were enrolled in the control group. Initial and follow-up evaluations were performed and analyzed. RESULTS: Fifteen and sixteen patients were evaluated in the control group and the biofeedback group, respectively. There was no statistically significant difference of LARS score between both groups. Decrease in Wexner score and increase in rectal capacity were significantly higher in the biofeedback group (odds ratio [OR], 5.386; 95% confidence interval [CI], 1.194–24.287; P = 0.028 and OR, 1.061; 95% CI, 1.002–1.123; P = 0.042). CONCLUSION: Biofeedback therapy was superior for objective improvement of pelvic function to observation in LARS. It can be considered to induce more rapid improvement of major LARS.

OBJECTIVETo observe the multiple symptom distribution, severity and quality of life of female pelvic floor dysfunction(FPFD) patients with constipation as chief complaint.

METHODSOne hundred FPFD patients with constipation as chief complaint from Speciaty Outpatient Clinic, Pelvic Floor Center of Nanjing Municipal Hospital of Traditional Chinese Medicine between September 2015 and February 2017 were retrospectively enrolled in this study. A comprehensive medical history questionnaire survey and systematical evaluation of severity and quality of life of these patients with constipation was conducted. Constipation scoring system scale (CSS) and patient-assessment of constipation quality of life questionnaire (PAC-QOL) were applied to evaluate the constipation. Other scales included: (1)pain visual analogue scale (VAS) and short form-36 questionnaire (SF-36): if combined with chronic functional anal rectal pain; (2) international consultation on incontinence questionnaire-short form (ICIQ-SF) and urinary incontinence quality of life questionnaires (I-QOL):if combined with urinary incontinence; (3) fecal incontinence severity score scale (Wexner-FIS) and fecal incontinence quality of life questionnaire (FI-QOL):if combined with fecal incontinence.

RESULTSThe mean age of 100 FPFD patients was (57.9±13.9) (24-89) years and the mean disease course was (7.0±8.2)(0.5-40.0) years. Seventy-five cases (75%) were complicated with anal pain, 70 with urinary incontinence, 37 with rectocele, 19 with nocturia, 11 with urinary frequency, 10 with defecation incontinence. Complication with only one symptom was observed in 20 cases (20%), and with two or more symptoms was observed in 80 cases (80%). Pelvic floor relaxation syndrome patients were dominant (58 cases, 58%). The severity of constipation (CSS) was 6-22 (13.89±3.79) points and the quality of life (PAC-QOL) was 45-133 (87.13±18.57) points in FPFD patients. VAS and SF-36 of patients combined with chronic functional anal rectal pain were 1-8 (3.0±1.9) points and 14.4-137.0(71.5±31.4) points respectively. ICIQ-SF and I-QOL of patients combined with urinary incontinence were 1-17 (6.1±3.6) points and 52-110 (90.0±15.8) points respectively. Wexner-FIS and FI-QOL of patients combined with fecal incontinence were 1-11 (4.4±3.0) points and 52-116 (83.4±23.3) points respectively.

CONCLUSIONSThe symptoms of FPFD patients with constipation as chief complaint are complex. They are mainly complicated with anal diseases, then urinary incontinence, and mostly with more than 2 symptoms. Their quality of life is poor.

PURPOSE: Although numerous procedures have been proposed for the treatment of patients with a rectal prolapse, the most effective operation has not yet been established. Minimal rectal mobilization can prevent constipation; however, it is associated with increased recurrence rates. We describe our novel method for a laparoscopic posterolateral rectopexy, which includes rectal mobilization with a posterior-right unilateral dissection, suture fixation to the sacral promontory with a polypropylene mesh (Optilene), and a mesorectal fascia propria that is as wide as possible. The present report describes our novel method and assesses the short-term outcomes of patients. METHODS: Between June 2014 and June 2017, 63 patients (28 males and 35 females) with a full-thickness rectal prolapse underwent a laparoscopic posterolateral (LPL) rectopexy. We retrospectively analyzed the clinical characteristics and postoperative complications in those patients. The outcome of surgery was determined by evaluating the answers on fecal incontinence questionnaires, the results of anal manometry preoperatively and 3 months postoperatively, the patients’ satisfaction scores (0–10), and the occurrence of constipation. RESULTS: No recurrence was reported during follow-up (3.26 months), and 3 patients reported postoperative complications (wound infection, postoperative sepsis, which was successfully treated with conservative management, and retrograde ejaculation). Compared to the preoperative baseline, fecal incontinence at three months postoperatively showed an overall improvement. The mean patient satisfaction score was 9.55 ± 0.10, and 8 patients complained of persistent constipation. CONCLUSION: LPL rectopexy is a safe, effective method showing good functional outcomes by providing firm, solid fixation for patients with a full-thickness rectal prolapse.

PURPOSE: A cutting seton is used after a partial distal fistulotomy to treat patients with a high exrasphincteric fistula in ano to avoid fecal incontinence and recurrence. In Saudi Arabia, religious practices necessitate complete cleanness, which makes conditions affecting anal continence a major concern to patients affected by an anal fistula. Therefore, we aimed to evaluate the efficiency of the cutting seton in treating a high anal fistula among Saudi Arabians. METHODS: Between January 2005 and December 2014, a prospective study was done for 372 Saudi Arabian patients diagnosed as having a high anal fistula and treated with a cutting seton at Al-Ansar General Hospital, Medina, Saudi Arabia. 0-silk sutures were used. All patients underwent the same preoperative assessment, operative technique, and postoperative follow-up. Weekly, the seton was tightened in outpatient clinics. RESULTS: Two hundred ninety-eight patients (80.1%) were males and 74 (19.9%) females. The duration of symptoms varied from 3–21 months. The fistula healed completely in 363 patients (97.6%); 58 patients (15.6%) reported some degree of incontinence to flatus, but none to feces. In 9 patients (2.4%) the fistula recurred. CONCLUSION: The utilization of the cutting seton method in the treatment of patients with a high anal fistula is highly efficient as it simultaneously drains the abscess, cuts the fistulous tract, and causes fibrosis along the tract. Treatment of a high anal fistula by using a staged fistulotomy with a cutting seton was very rewarding to Saudi Arabian patients who feared anal incontinence for religious reasons and was associated with low postoperative complication and recurrence rates.

Because of the improvement of surgical technique and the widely use of multimodality therapy, more patients with rectal cancer undergo sphincter-preserving surgery. However, it has been reported that up to 90% of such patients will suffer from bowel dysfunction, ranging from increased bowel frequency to faecal incontinence or evacuatory dysfunction. This wide spectrum of symptoms after resection of the rectum has been termed anterior resection syndrome (ARS). This disordered bowel function has a substantial negative effect on quality of life, however, the causal mechanisms have not been clarified. The present review discusses the clinical manifestation, underlying mechanisms, as well as prevention and treatment strategies.
