Restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis:A narrative review

Restorative proctocolectomy with ileal pouch-anal anastomosis(RP-IPAA) is the gold standard surgical treatment for ulcerative colitis.However,despite the widespread use of RP-IPAA,many aspects of this treatment still remain controversial,such as the approach(open or laparoscopic),number of stages in the surgery,type of pouch,and construction type(hand-sewn or stapled ileal pouch-anal anastomosis).The present narrative review aims to discuss current evidence on the short-,mid-,and long-term results of each of these technical alternatives as well as their benefits and disadvantages.A review of the MEDLINE,EMBASE,and Ovid databases was performed to identify studies published through March 2016.Few large,randomized,controlled studies have been conducted,which limits the conclusions that can be drawn regarding controversial issues.The available data from retrospective studies suggest that laparoscopic surgery has no clear advantages compared with open surgery and that one-stage RP-IPAA may be indicated in selected cases.Regarding 2- and 3-stage RP-IPAA,patients who underwent these surgeries differed significantly with respect to clinical and laboratory variables,making any comparisons extremely difficult.The long-term results regarding the pouch type show that the W- and J-reservoirs do not differ significantly,although the J pouch is generally preferred by surgeons.Hand-sewn and stapled ileal pouch-anal anastomoses have their own advantages,and there is no clear benefit of one technique over the other.

AIM: To investigate the outcomes of treatments for complications after ileal pouch-anal anastomosis (IPAA) in Korean patients with ulcerative colitis.

Eviendep~ reduces number and size of duodenal polyps in familial adenomatous polyposis patients with ileal pouchanal anastomosis

AIM:To evaluate if 3 mo oral supplementation with Eviendep was able to reduce the number of duodenal polyps in familial adenomatous polyposis(FAP)patients with ileal pouch-anal anastomosis(IPAA).METHODS:Eleven FAP patients with IPAA and duodenal polyps were enrolled.They underwent upper gastrointestinal(GI)endoscopy at the baseline and after 3 mo of treatment.Each patient received 5 mg Eviendep twice a day,at breakfast and dinner time,for3 mo.Two endoscopists evaluated in a blinded manner the number and size of duodenal polyps.Upper GI endoscopies with biopsies were performed at the baseline(T0)with the assessment of the Spigelman score.Polyps>10 mm were removed during endoscopy and at the end of the procedure a new Spigelman score was determined(T1).The procedure was repeated 3 mo after the baseline(T2).Four photograms were examined for each patient,at T1 and T2.The examined area was divided into 3 segments:duodenal bulb,second and third portion duodenum.Biopsy specimens were taken from all polyps>10 mm and from all suspicious ones,defined by the presence of a central depression,irregular surface,or irregular vascular pattern.Histology was classified according to the updated Vienna criteria.RESULTS:At baseline the mean number of duodenal detected polyps was 27.7 and mean sizes were 15.8mm;the mean Spigelman score was 7.1.After polypectomy the mean number of duodenal detected polyps was 25.7 and mean sizes were 7.6 mm;the mean Spigelman score was 6.4.After 3 mo of Eviendep bid,all patients showed a reduction of number and size of duodenal polyps.The mean number of duodenal polyps was 8(P=0.021)and mean size was 4.4 mm;the mean Spigelman score was 6.6.Interrater agreement was measured.Lesions>1 cm found a very good degree of concordance(kappa 0.851)and a good concordance was as well encountered for smaller lesions(kappa 0.641).CONCLUSION:Our study demonstrated that shortterm(90 d)supplementation with Eviendep in FAP patients with IPAA and with recurrent adenomas in the duodenal mucosa,resulted effective in reducing polyps number of 32%and size of 51%.

Laparoscopic restorative proctocolectomy with ileal pouch-anal anastomosis for Peutz-Jeghers syndrome with synchronous rectal cancer

We report on a patient diagnosed with PeutzJeghers syndrome(PJS) with synchronous rectal cancer who was treated with laparoscopic restorative proctocolectomy with ileal pouch-anal anastomosis(IPAA). PJS is an autosomal dominant syndrome characterized by multiple hamartomatous polyps in the gastrointestinal tract, mucocutaneous pigmentation, and increased risks of gastrointestinal and nongastrointestinal cancer. This report presents a patient with a 20-year history of intermittent bloody stool, mucocutaneous pigmentation and a family history of PJS, which together led to a diagnosis of PJS. Moreover, colonoscopy and biopsy revealed the presence of multiple serried giant pedunculated polyps and rectal adenocarcinoma. Currently, few options exist for the therapeutic management of PJS with synchronous rectal cancer. For this case, we adopted an unconventional surgical strategy and ultimately performed laparoscopic restorative proctocolectomy with IPAA. This procedure is widely considered to be the first-line treatment option for patients with ulcerative colitis or familial adenomatous polyposis. However, there are no previous reports of treating PJS patients with laparoscopic IPAA. Since the operation, the patient has experienced no further episodes of gastrointestinal bleeding and has demonstrated satisfactory bowel control. Laparoscopic restorative proctocolectomy with IPAA may be a safe and effective treatment for patients with PJS with synchronous rectal cancer.

Ileal pouch anal anastomosis with modified double-stapled mucosectomy-the experience in China

AIM:To investigate the feasibility and long-term functional outcome of ileal pouch-anal anastomosis with modified double-stapled mucosectomy.METHODS:From January 2002 to March 2011,fourtyfive patients underwent ileal pouch anal anastomosis with modified double-stapled mucosectomy technique and the clinical data obtained for these patients were reviewed.RESULTS:Patients with ulcerative colitis(n = 29) and familial adenomatous polyposis(n = 16) underwent ileal pouch-anal anastomosis with modified doublestapled mucosectomy.Twenty-eight patients underwent one-stage restorative proctocolectomy,ileal pouch anal anastomosis,protective ileostomy and the ileostomy was closed 4-12 mo postoperatively.Two-stage procedures were performed in seventeen urgent patients,proctectomy and ileal pouch anal anastomosis were completed after previous colectomy with ileostomy.Morbidity within the first 30 d of surgery occurred in 10(22.2%) patients,all of them could be treated conservatively.During the median follow-up of 65 mo,mild to moderate anastomotic narrowing was occurred in 4 patients,one patient developed persistent anastomotic stricture and need surgical intervention.Thirtyfive percent of patients developed at least 1 episode of pouchitis.There was no incontinence in our patients,the median functional Oresland score was 6,3 and 2 after 1 year,2.5 years and 5 years respectively.Nearly half patients(44.4%) reported "moderate functioning",37.7% reported "good functioning",whereas in 17.7% of patients "poor functioning" was observed after 1 year.Five years later,79.2% of patients with good function,16.7% with moderate function,only 4.2% of patients with poor function.CONCLUSION:The results of ileal pouch anal anastomosis with modified double-stapled mucosectomy technique are promising,with a low complication rate and good long-term functional results.

Management of pouch related symptoms in patients who underwent ileal pouch anal anastomosis surgery for adenomatous polyposis

BACKGROUND Adenomatous polyposis syndromes(APS)patients with ileal pouch anal anastomosis(IPAA)suffer frequent symptoms with scarce signs of inflammation,distinct from ulcerative colitis patients.While the management of pouchitis in ulcerative colitis patients is well established,data regarding response to treatment modalities targeting pouch-related disorders in APS patient population is scarce.AIM To assess clinical,endoscopic and histologic response to various treatment modalities employed in the therapy of pouch related disorders.METHODS APS patients who underwent IPAA between 1987-2019 were followed every 6-12 mo and pouch-related symptoms were recorded at every visit.Lower endoscopy was performed annually,recording features of the pouch,cuff and terminal ileum.A dedicated gastrointestinal pathologist reviewed biopsies for signs and severity of inflammation.At current study,files were retrospectively reviewed for initiation and response to various treatment modalities between 2015-2019.Therapies included dietary modifications,probiotics,loperamide,antibiotics,bismuth subsalicylate,mebeverine hydrochloride,5-aminosalicylic acid compounds and topical rectal steroids.Symptoms and endoscopic and histologic signs of inflammation before and after treatment were assessed.Pouchitis disease activity index(PDAI)and its subscores was calculated.Change of variables before and after therapy was assessed using Wilcoxon signed rank test for continuous variables and using McNemar's test for categorical variables.RESULTS Thirty-three APS patients after IPAA were identified.Before treatment,16 patients(48.4%)suffered from abdominal pain and 3(9.1%)from bloody stools.Mean number of daily bowel movement was 10.3.Only 4 patients(12.1%)had a PDAI≥7.Mean baseline PDAI was 2.5±2.3.Overall,intervention was associated with symptomatic relief,mainly decreasing abdominal pain(from 48.4%to 27.2%of patients,P=0.016).Daily bowel movements decreased from a mean of 10.3 to 9.3(P=0.003).Mean overall and clinical PDAI scores decreased from 2.58 to 1.94(P=0.016)and from 1.3 to 0.87(P=0.004),respectively.Analyzing each treatment modality separately,we observed that dietary modifications decreased abdominal pain(from 41.9%of patients to 19.35%,P=0.016),daily bowel movements(from 10.5 to 9.3,P=0.003),overall PDAI(from 2.46 to 2.03,P=0.04)and clinical PDAI(1.33 to 0.86,P=0.004).Probiotics effectively decreased daily bowel movements(from 10.2 to 8.8,P=0.007),overall and clinical PDAI(from 2.9 to 2.1 and from 1.38 to 0.8,P=0.032 and 0.01,respectively).While other therapies had minimal or no effects.No significant changes in endoscopic or histologic scores were seen with any therapy.CONCLUSION APS patients benefit from dietary modifications and probiotics that improve their pouch-related symptoms but respond minimally to anti-inflammatory and antibiotic treatments.These results suggest a functional rather than inflammatory disorder.

Lactobacillus acidophilus alleviates pouchitis after ileal pouch-anal anastomosis in rats

AIM To assess the therapeutic potential of Lactobacillus acidophilus(LA) for the treatment of pouchitis in a rat model.METHODS Sprague Dawley rats underwent proctocolectomy and ileal pouch-anal anastomosis followed by administration of dextran sulfate sodium(DSS) to induce pouchitis. Rats with pouchitis were randomly divided into three groups: no intervention(NI), normal saline(NS, 3 m L/d normal saline for 7 d), and LA(3 m L/d LA at 1× 1010 colony-forming units for 7 d). General body condition was recorded and pouch specimens were obtained for histological examination. m RNA expression levels of interleukin(IL)-1β, IL-6, IL-10, and tumor necrosis factor-α were determined by RT-PCR. Zonula occludens protein 1(ZO-1) levels were measured by immunohistochemistry. RESULTS LA reduced weight loss associated with pouchitis(P < 0.05) and improved the symptoms of pouchitis in rats. Compared with the NI and NS groups, rats in the LAgroup showed earlier disappearance of hematochezia(6.17 ± 0.75, 6.50 ± 0.55, 3.17 ± 0.75, P < 0.05) and higher fecal scores(2.67 ± 0.48, 2.50 ± 0.51, 4.42 ± 0.50, respectively, P < 0.05). Histological scores were also lower in the LA group compared with the other two groups(7.17 ± 0.98, 8.00 ± 0.89, 4.00 ± 0.89, respectively, P < 0.05). m RNA expression levels of IL-1β, IL-6, and tumor necrosis factor-α were significantly reduced, while IL-10 m RNA levels were significantly increased in the LA group(P < 0.05, respectively). ZO-1 protein levels were also significantly increased after administration of LA(P < 0.05). CONCLUSION LA alleviates pouchitis induced by DSS after ileal pouchanal anastomosis by decreasing pro-inflammatory factors and increasing anti-inflammatory factors, and restoring ZO-1 expression in the mucosa.

Long-axis rotational volvulus in an ileal J-pouch anal anastomosis: A preventable rare complication

Puropose: This study was designed to report a very rare long-term complication of ileal-Jpouch anal anastomosis: An 180 degree longaxial rotational volvulus causing J pouch obstruction. Methods: An Ovid and Medline search using the following keywords was performed: J pouch ileoanal anastomosis, J-pouch ileoanal anastomosis complications, J-pouch volvulus, J-pouch complications, restorative proctocolectomy complications, and restorative proctocolectomy volvulus. One J-pouch ileoanal anastomosis 180° volvulus report was found [1]. Result: We describe a long-axis 180° rotational volvulus complication of a J-pouch ileoanal anastomosis. The J pouch was performed three years prior after the laparoscopic total proctocolectomy for chronic ulcerative colitis. Pouch excision and new ileoanal J-pouch surgery were then performed along with pexy using alloderm mesh placement with excellent outcomes. Conclusion: Long-axis 180° rotational volvulus is a rare complication of a J-pouch ileoanal anastomosis. Pouch dysfunction after a long-axis rotational volvulus is an uncommon cause of acute abdomen. Lack of adhesions and pouch size are risk factors for the pouch torsion. Prompt diagnosis and treatment are essential for the pouch salvage. Simple abdominal x-ray, barium enema and CT scan represent important tools for diagnosis. Salvage surgery should be performed even if detorsion and decompression of the affected bowel are achieved. Surgery has excellent outcomes if performed after the prompt diagnosis. Pouch pexy should be done to prevent recurrent volvulus.

Ileal pouch surgery for ulcerative colitis

Ulcerative colitis (UC) is a relapsing and remitting disease characterised by chronic mucosal and submucosal inflammation of the colon and rectum. Treatment may vary depending upon the extent and severity of inflammation. Broadly speaking medical treatments aim to induce and then maintain remission. Surgery is indicated for inflammatory disease that is refractory to medical treatment or in cases of neoplastic transformation. Approximately 25% of patients with UC ultimately require colectomy. Ileal pouch-anal anastomosis (IPAA) has become the standard of care for patients with ulcerative colitis who ultimately require colectomy. This review will examine indications for IPAA, patient selection, technical aspects of surgery, management of complications and long term outcome following this procedure.

Risk of ileal pouch neoplasms in patients with familial adenomatous polyposis

Restorative proctocolectomy is the most common surgical option for patients with familial adenomatous polyposis(FAP). However,adenomas may develop in the ileal pouch mucosa over time,and even carcinoma in the pouch has been reported. We therefore reviewed the prevalence,nature,and treatment of adenomas and carcinoma that develop after proctocolectomy in the ileal pouch mucosa in patients with FAP. In 25 reports that were reviewed,the incidence of adenomas in the ileal pouch varied from 6.7% to 73.9%. Several potential factors that favor the development of pouch polyposis have been investigated,but many remain controversial. Nevertheless,it seems certain that the age of the pouch is important. The risk appears to be 7%to 16% after 5 years,35% to 42% after 10 years,and75% after 15 years. On the other hand,only 21 cases of ileal pouch carcinoma have been recorded in the literature to date. The diagnosis of pouch carcinoma was made between 3 to 20 years(median,10 years) after pouch construction. Although the risk of malignant transformation in ileal pouches is probably low,it is not negligible,and the long-term risk cannot presently be well quantified. Regular endoscopic surveillance,especially using chromoendoscopy,is recommended.

Clinical outcome of ileal pouch-anal anastomosis for chronic ulcerative colitis in China

Background The incidence of chronic ulcerative colitis （CUC） in China is remarkably increasing, while little information on surgical treatment has been reported. This study aimed to completely describe and analyze the clinical outcome of restorative proctocolectomy with ileal pouch-anal anastomosis （IPAA）for CUC in China. Methods Ninety-five consecutive patients, who suffered CUC and had surgical indications, were carefully selected. All patients underwent IPAA. Data on patient characteristics, surgical indications, surgical details, postoperative complications, functional outcome, and quality of life were collected. Results The mean patient age at the time of the operation was 32 years. Twenty-nine （31%） patients underwent an emergency operation, and 66 （69%） underwent elective procedures. Four patients with severe dysplasia underwent operations, but no carcinoma was histologically confirmed. A two-stage operation was performed in 87 （92%） patients, and a hand-sewn technique was applied in 88 （93%） patients. Sixteen patients （17.0%） experienced early complications, and there was a significant difference between the emergency surgery group and the elective group （31.0% vs. 10.6%, respectively; P 〈0.01）. Five （5.3%） patients developed pouchitis as a late complication. The mean stool frequency after the operation was 4.6 （2-11） during the first 24 hours and 1.5 （0-4） overnight. According to the Kirwan grading scale, 87 （91.8%） patients showed satisfactory anal continence function. The quality of life improved significantly from a preoperative mean value of 0.28-0.61 before ileostomy closure to 0.78 after ileostomy closure （P 〈0.01） according to the Cleveland Global Quality of Life index. Conclusions IPAA is an effective and safe surgical procedure for patients with CUC in China. However, some characteristics, such as the low incidence of pouchitis, require further study.

Volvulus of the ileal pouch-anal anastomosis:a meta-narrative systematic review of frequency,diagnosis,and treatment outcomes

Background:Proctocolectomy with ileal pouch–anal anastomosis(IPAA)is the surgical procedure of choice for medically refractory ulcerative colitis and familial adenomatous polyposis.While rare,a pouch volvulus can occur.We aimed to determine the frequency,presentation,and management approach of pouch volvulus in patients with IPAA.Methods:A systematic search of published literature was performed by a medical reference librarian on 10 August 2018 and two independent reviewers identified relevant publications,extracted data,and assessed the methodological quality based on a validated tool.A retrospective review of the Mayo Clinic electronic medical records identified one case of pouch volvulus between January 2008 and August 2018.Results:The frequency of pouch volvulus from one large published study reporting long-termoutcomes of IPAA was 0.18%(3/1,700).A total of 22 patients(18 ulcerative colitis)were included(median age 32 years,73%females).Median time to volvulus after IPAA was 36 months while median interval to volvulus diagnosis from symptom onset was 24 hours.Abdominal pain was the most commonly reported symptom(76%).The diagnosis was made primarily by abdominal computed tomography(13/17 patients,76%).Endoscopic treatment was successful in 1 of 11 patients(9%).Surgery was performed in 20 patients and pouch-pexy and pouch excision were the most frequent surgical operations.A redo IPAA was performed in five patients(25%).Conclusion:Pouch volvulus is a rare but serious complication of IPAA and should be suspected even in the absence of obstruction symptoms.Endoscopic treatment often fails and surgery is effective when performed early.

Infliximab for the treatment of pouchitis

Pouchitis is not a rare complication that develops after an ileal-pouch anastomosis, performed after colectomy in patients refractory to treatment or with complicated ulcerative colitis. This condition may become chronic and unresponsive to medical therapies, including corticosteroids, antibiotics and probiotics. The advent of biological therapies(tumor necrosis factor-α inhibitors) has changed the course of these complications. In particular, in these cases, infliximab(IFX) may represent a safe and effective therapy in order to avoid the subsequent operation for a permanent ileostomy. This article reviews the therapeutic effects of one of the most widely used anti-tumor necrosis factor-α molecules, IFX, for the treatment of complicated pouchitis(refractory to conventional treatment and/or fistulizing).

Cumulative incidence and risk factors for pouch adenomas associated with familial adenomatous polyposis following restorative proctocolectomy

BACKGROUND The emergence of restorative total proctocolectomy has significantly reduced the lifetime colorectal cancer risk associated with familial adenomatous polyposis(FAP).However,adenomas may develop in the ileal pouch over time and may even progress to carcinoma.We evaluated the cumulative incidence,time to development,and risk factors associated with ileal pouch adenoma.AIM To evaluate the cumulative incidence,time to development,and risk factors associated with pouch adenoma.METHODS In this retrospective,observational study conducted at a tertiary center,95 patients with FAP who underwent restorative proctocolectomy at our center between 1989 and 2018 were consecutively included.The mean follow-up period was 88 mo.RESULTS Pouch adenomas were found in 24(25.3%)patients,with a median time of 52 mo to their first formation.Tubular adenomas were detected in most patients(95.9%).There were no high-grade dysplasia or malignancies.Of the 24 patients with pouch adenomas,13 had all detected adenomas removed.Among the 13 patients who underwent complete adenoma removal,four(38.5%)developed recurrence.Among 11(45.8%)patients with numerous polyps within the pouch,seven(63.6%)exhibited progression of pouch adenoma.The cumulative risks of pouch adenoma development at 5,10,and 15 years after pouch surgery were 15.2%,29.6%,and 44.1%,respectively.Severe colorectal polyposis(with more than 1000 polyps)was a significant risk factor for pouch adenoma development(hazard ratio,2.49;95% confidence interval:1.04-5.96;P=0.041).CONCLUSION Pouch adenomas occur at a fairly high rate in association with FAP after restorative proctocolectomy,and a high colorectal polyp count is associated with pouch adenoma development.

Diet of patients after pouch surgery may affect pouch inflammation

AIM:To investigate the diet of pouch patients compared to healthy controls,and to correlate pouch patients’diet with disease behavior.METHODS:Pouch patients were recruited and prospectively followed-up at the Comprehensive Pouch Clinic at the Tel Aviv Sourasky Medical Center.Pouch behavior was determined based on clinical,endoscopic and histological criteria.Healthy age-and sex-matched volunteers were selected from the"MABAT"Israeli Nutrition and Public Health Governmental Study and served as the control group.All the participants completed a 106-item food frequency questionnaire categorized into food groups and nutritional values based on those used in the United States Department of Agriculture food pyramid and the Israeli food pyramid.Data on Dietary behavior,food avoidance,the use of nutritional supplements,physical activity,smoking habits,and body-mass index(BMI)were also obtained.Pouch patients who had familial adenomatous polyposis(n=3),irritable pouch syndrome(n=4),or patients whose pouch surgery took place less than one year previously(n=5)were excluded from analysis.RESULTS:The pouch patients(n=80)consumed significantly more from the bakery products food group(1.2±1.4 servings/d vs 0.6±1.1 servings/d,P<0.05)and as twice as many servings from the oils and fats(4.8±3.4 servings/d vs 2.4±2 servings/d,P<0.05),and the nuts and seeds food group(0.3±0.6 servings/d vs 0.1±0.4 servings/d,P<0.05)compared to the controls(n=80).The pouch patients consumed significantly more total fat(97.6±40.5 g/d vs 84.4±39 g/d,P<0.05)and fat components[monounsaturated fatty acids(38.4±16.4 g/d vs 30±14 g/d,P<0.001),and saturated fatty acids(30±15.5 g/d vs 28±14.1 g/d,P<0.00)]than the controls.In contrast,the pouch patients consumed significantly fewer carbohydrates(305.5±141.4 g/d vs 369±215.2 g/d,P=0.03),sugars(124±76.2 g/d vs 157.5±90.4 g/d,P=0.01),theobromine(77.8±100 mg/d vs 236.6±244.5 mg/d,P<0.00),retinol(474.4±337.1μg/d vs 832.4±609.6μg/d,P<0.001)and dietary fibers(26.2±15.4 g/d vs 30.7±14 g/d,P=0.05)than the controls.Comparisons of the food consumption of the patients without(n=23)and with pouchitis(n=45)showed that the former consumed twice as many fruit servings as the latter(3.6±4.1 servings/d vs 1.8±1.7 servings/d,respectively,P<0.05).In addition,the pouchitis patients consumed significantly fewer liposoluble antioxidants,such as cryptoxanthin(399±485μg/d vs 890.1±1296.8μg/d,P<0.05)and lycopene(6533.1±6065.7μg/d vs 10725.7±10065.9μg/d,P<0.05),and less vitamin A(893.3±516μg/d vs1237.5±728μg/d,P<0.05)and vitamin C(153.3±130 mg/d vs 285.3±326.3 mg/d,P<0.05)than the patients without pouchitis.The mean BMI of the pouchitis patients was significantly lower than the BMI of the patients with a normal pouch:22.6±3.2 vs 27±4.9(P<0.001).CONCLUSION:Decreased consumption of antioxidants by patients with pouchitis may expose them to the effects of inflammatory and oxidative stress and contribute to the development of pouchitis.

目的探讨家族性腺瘤性息肉病(FAP)患者结直肠癌变外科预防的手术时机和术式选择。方法回顾性分析我院近年来连续诊治的43例FAP患者结直肠癌的发病状况及预防性手术治疗的疗效。结果未经手术干预的FAP患者,20岁、25岁、30岁、35岁、40岁、45岁、50岁时的累积结直肠癌变风险分别约为0、10.4%、25.3%、32.4%、63.0%、76.9%、86.2%;发生结直肠癌变的病例中有84.6%发生直肠癌变。11例患者在我院接受了预防性手术治疗,无手术死亡,3例全结直肠切除、回肠J-Pouch肛管手工吻合术患者术后并发吻合口瘘。1例结肠次全切除的患者于术后13年直肠癌变。3例回肠J-Pouch肛管吻合患者无肛门失禁,每日排便4～6次。结论FAP患者预防性手术治疗时机应在20岁之前,最迟不超过25岁,全结直肠切除、回肠J-Pouch肛管吻合器吻合术预防结直肠癌变安全有效,适合作为预防性手术的首选术式。
