Intra-abdominal desmoid tumors in familial adenomatous polyposis: How much do clinical and surgical variables interfere with their development?

Abstract Objective: Familial Adenomatous Polyposis is a complex hereditary disease that exposes the carrier to a great risk of Colorectal Cancer (CRC). After prophylactic surgery, intra-abdominal desmoid tumors are known to be one the most important cause of death. Therefore, recognition of increased-risk patients and modification of operative strategy may be crucial. Aim: The objective of this study was to estimate the desmoid tumor risk in relation to various surgical and clinical variables. Methods: Patients who had undergone polyposis since 1958 were included in the study. After exclusion criteria were met, those who had developed desmoid tumors were selected to undergo further evaluation. Results: The study revealed that the risk of developing desmoid tumors was associated with various factors such as sex ratio, colectomy, and reoperations. On the other hand, the type of surgery, family history, and surgical approach did not affect the risk of developing desmoid tumors. The data collected from 146 polyposis patients revealed that 16% had desmoid polyps. The sex ratio was 7:1, and the median age at colectomy was 28.6 years. Family history, multiple abdominal operations, and reoperations were some of the characteristics that were common in desmoid patients. Conclusion: Recognition of clinical (female sex) and surgical (timing of surgery and previous reoperations) data as unfavorable variables associated with greater risk may be useful during the decision-making process.

Reservoritis secundaria a infección por citomegalovirus: reporte de caso y revisión de la literatura / Pouchitis secondary to cytomegalovirus infection: Case report and literature review

Resumen La proctocolectomía total con reservorio ileal es el procedimiento quirúrgico de elección para la colitis ulcerativa refractaria (CUR) al tratamiento médico y la reservoritis es la complicación más frecuente y puede afectar hasta al 50% de los pacientes en los primeros 5 años del procedimiento. Aunque la etiología no está bien establecida, su presentación podría estar relacionada con disbiosis como resultado de la estasis fecal en individuos genéticamente susceptibles y con una respuesta inmunitaria alterada. Los síntomas típicos de reservoritis como diarrea, dolor abdominal, tenesmo, urgencia, incontinencia fecal y, menos frecuentemente, sangrado rectal no son específicos y el diagnóstico debe confirmarse mediante una evaluación endoscópica e histológica. La infección por citomegalovirus es infrecuente como causa de reservoritis; sin embargo, debe considerarse en pacientes con reservoritis refractaria al manejo antibiótico inicial. Las pruebas diagnósticas incluyen pruebas serológicas como la medición de anticuerpos, antigenemia y proteína C-reactiva (PCR) en sangre. El tratamiento de elección es el ganciclovir, medicamento de administración endovenosa que puede inducir complicaciones graves como mielosupresión, neutropenia y trombocitopenia. Se recomienda el seguimiento endoscópico posterior al tratamiento para asegurar la cicatrización mucosa, especialmente cuando hay sospecha de enfermedad de Crohn o compromiso del asa aferente en la endoscopia inicial.

Abstract Total proctocolectomy with ileal pouch is the surgical procedure of choice for ulcerative colitis refractory to medical treatment, and pouchitis is the most frequent complication. It can affect up to 50% of patients in the first five years of the procedure. Although the etiology is not well established, its manifestation could be related to dysbiosis resulting from fecal stasis in genetically susceptible individuals with altered immune responses. Typical symptoms of pouchitis, such as diarrhea, abdominal pain, tenesmus, urgency, fecal incontinence, and, less commonly, rectal bleeding, are nonspecific, and the diagnosis must be confirmed by endoscopic and histologic examination. Cytomegalovirus infection is an infrequent cause of pouchitis; however, it should be considered in patients with pouchitis refractory to initial antibiotic management. Diagnostic tests include serological tests such as the measurement of antibodies, antigenemia, and C-reactive protein (CRP) in blood. The treatment of choice is ganciclovir, an intravenous drug that can induce severe complications such as myelosuppression, neutropenia, and thrombocytopenia. Post-treatment endoscopic follow-up is recommended to ensure mucosal healing, especially when there is suspicion of Crohn's disease or involvement of the afferent loop on initial endoscopy.

A rare case of obstructive ileus due to ileal pouch torsion: a case report and systematic review

Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become the standard surgical treatment for ulcerative colitis patients. Among others, it is important for clinicians to be aware of a rare, though urgent situation, the ileal pouch torsion. A high degree of suspicion is essential as obstruction due to pouch torsion is not likely to resolve conservatively. Delay in diagnosis and treatment can lead to pouch jeopardy and life-threatening complications. The aim of this study was to present a systematic review of the literature combined with the presentation of a case report of our department regarding this rare entity. A systematic literature review according to QUORUM guidelines was conducted in July 2019 using MEDLINE, SCOPUS, and COCHRANE databases. We included studies reporting pouch torsion after IPAA in English or German language with no restriction regarding publication time.  Outcomes after different treatment options, such as operative pouch detorsion, and/or pouchpexy, and/or pouch reconstruction, and/or end-ileostomy through laparoscopic or open procedures were evaluated. We identified 170 publications. After duplicates and irrelevant articles have been excluded, 25 publications remained for full-text review. Finally, 12 articles were included in this systematic review, concerning 14 cases. To the best of our knowledge, this is the first comprehensive systematic review on this topic to date.

Functional outcomes in patients submitted to restorative proctocolectomy with ileal pouch anal anastomosis in a single tertiary center / Resultados funcionais em pacientes submetidos a proctocolectomia restauradora com anastomose íleoanal e bolsa ileal em um centro terciário

ABSTRACT Background: Functional results after restorative proctocolectomy for ulcerative colitis and familial adenomatous polyposis are variable. We assessed functional results in patients with ileal pouch anal anastomosis and evaluated potential factors associated with poor functional results. Methods: Retrospective cohort study of 38 patients who were submitted to a restorative proctocolectomy with ileal pouch anal anastomosis, in the context of ulcerative colitis and familial adenomatous polyposis, in at tertiary referral center, in the period between 1993 and 2013. Clinical records were analyzed and telephone interviews with protocoled questionnaire to 32 patients (12 ulcerative colitis, 20 familial adenomatous polyposis) were performed. Pouch functional results were also evaluated based in the Oresland score. The functional results were analyzed at four points of the patient outcome. Results: In 25 patients were performed restorative proctocolectomy with ileal pouch anal anastomosis and in 7 patients total colectomy preceded protectomy with ileal pouch anal anastomosis. Protective ileostomy was performed in all patients. There was no mortality and post-operative complications related with the pouch was 12.5% but treated conservatively. The mean follow-up was 13.2 years. Pouch failure occurs in 9.4% (2 in familial adenomatous polyposis and 1 in ulcerative colitis). Familial adenomatous polyposis patients achieved the best outcome but the outcome was acceptable in both groups. The median Oresland score was good with small variations over the years, although the best score being reached at 5 years after the surgery. Conclusions: The long-term results in patients undergoing restorative proctocolectomy with ileal pouch anal anastomosis were good in both groups, although better in familial adenomatous polyposis. In both, the best score of functional results seems to be reached at 5 years after surgery.

RESUMO Introdução: Os resultados funcionais após proctocolectomia restauradora em casos de colite ulcerativa e polipose adenomatosa familiar são variáveis. Avaliamos os resultados funcionais em pacientes com anastomose ileoanal e bolsa ileal bem como os fatores potenciais associados a resultados funcionais fracos. Métodos: Estudo retrospectivo de coorte com 38 pacientes submetidos a proctocolectomia restauradora com anastomose ileoanal e bolsa ileal, no contexto de colite ulcerativa e polipose adenomatosa familiar, em um centro de referência terciário, no período entre 1993 e 2013. Analisamos os registos clínicos e realizamos entrevistas telefónicas com um questionário protocolado a 32 pacientes (12 colite ulcerativa, 20 polipose adenomatosa familiar). Também foram avaliados os resultados funcionais da bolsa, com base no escore de Oresland. Os resultados funcionais foram analisados em quatro pontos do desfecho de cada paciente. Resultados: Em 25 pacientes foi realizada proctocolectomia restauradora com anastomose ileoanal e bolsa ileal, e em 7 pacientes uma colectomia total precedeu a protectomia com anastomose ileoanal e bolsa ileal. Todos os pacientes foram submetidos a uma ileostomia protetora. Não ocorreram óbitos e as complicações pós-operatórias relacionadas com a bolsa chegaram a 12,5%, mas foram tratadas conservadoramente. O seguimento médio foi de 13,2 anos. Ocorreu defeito na bolsa em 9,4% (2 em polipose adenomatosa familiar e 1 em colite ulcerativa). Os pacientes com polipose adenomatosa familiar obtiveram o melhor resultado; contudo, em ambos os grupos o resultado foi considerado aceitável. A mediana do score de Oresland foi boa, tendo sido observadas pequenas variações ao longo dos anos, embora o melhor score tenha sido verificado 5 anos após a cirurgia. Conclusões: A longo prazo, os resultados para os pacientes submetidos a proctocolectomia restauradora com anastomose ileoanal e bolsa ileal foram bons em ambos os grupos, embora tenham sido considerados melhores nos pacientes com polipose adenomatosa familiar. Nos dois grupos, o melhor escore de resultados funcionais parece ser alcançado por volta dos 5 anos após a cirurgia.

Clinical efficacy of laparoscopic and open total proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis / 中华消化外科杂志

Objective To compare the short-term and long-term outcomes between laparoscopic and open total proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC).Methods The retrospective cohort study was conducted.The clinical data of 150 UC patients who underwent total proctocolectomy with IPAA in the Renji Hospital of Shanghai Jiaotong University between January 2003 and December 2016 were collected.Among 150 patients,87 undergoing laparoscopic total proctocolectomy with IPAA and 63 undergoing open total proctocolectomy with IPAA were respectively allocated into the laparoscopy group and open group.Observation indicators:(1) comparisons of intra-and post-operative situations;(2) postoperative complications;(3) follow-up situation.Follow-up using outpatient examination and telephone interview was performed to detect postoperative recovery and complications up to December 2017.Measurement data with normal distribution were represented as x-±s and comparison between groups was analyzed using the t test.Comparison between groups of count data was analyzed using the chi-square test.Results (1) Comparisons of intra-and post-operative situations:operation time,volume of intraoperative blood loss,time of initial intestinal stoma exsufflation and duration of hospital stay were respectively (306±3) minutes,(197± 12) mL,(62.1±1.8) hours,(8.2±0.4) days in the laparoscopy group and (224±4) minutes,(308±24) mL,(75.6±2.0) hours,(10.1±0.6) days in the open group,with statistically significant difference between groups (t =16.23,4.33,5.03,2.61,P＜ 0.05).All patients discharged successfully from hospital.All the 150 patients underwent stoma reversion of ileum at 3-12 months postoperatively,and the average time in the laparoscopy group and open group was respectively (6.0±5.6) months and (6.0±4.6)months,with no statistically significant difference between groups (t =0.01,P＞ 0.05).(2) Postoperative complications:cases with postoperative wound infection,retention of urine and frequency of defecation ＞ 4 times / day were respectively 2,8,21 in the laparoscopy group and 8,15,29 in the open group,with statistically significant differences between groups (x2 =5.25,4.37,0.96,P＜0.05).The cases with postoperative intestinal obstruction,anastomotic leakage,pelvic infection,pouch infection,pouch-related Crohn's disease and hyperplasia of ileal pouch were respectively 3,10,5,23,2,1 in the laparoscopy group and 8,7,4,24,1,0 in the open group,with no statistically significant differences between groups (x2=3.65,0.11,0.01,0.96,0.17,0.82,P＞0.05).Patients with postoperative complications were improved by acid suppression,fasting,anti-infection and fluid infusion.(3) Follow-up situation:150 patients were followed up for 12-60 months,with a median time of 48 months.There was no abnormality of postoperative anastomotic stoma and intestinal mucosa through comparison of colonoscopy results between pre-operation and 5 year postoperatively.During the follow-up,50 patients had shapeless stool and irregular defecation (times ＞ 4 times / day) at 3 years after stoma reversion of small intestine bypass,including 21 in the laparoscopy group and 29 in the open group,with a statistically significant differences between groups (x2 =4.72,P＜0.05).Eleven and 10 patients in the laparoscopy group and open group had shapeless stool and irregular defecation at 5 years postoperatively,but status were improved compared with the preoperative status,with no statistically significant difference between groups (x2=0.32,P ＞ 0.05).Conclusion The security of laparoscopic total proctocolectomy with IPAA for UC is equivalent to that of open total proctocolectomy,with the better short-term and long-term outcomes.

Surgical strategies of critical ulcerative colitis / 中华消化外科杂志

Surgical treatment of ulcerative colitis (UC) has received increasing attention.Total proctocolectomy with ileal pouch anal anastomosis (IPAA) has become a standard procedure.Acute severe UC (ASUC) is a difficult point of treatment.The commonly used strategy is to determine whether conversion therapy is performed after the observation of hormone therapy.Critical UC (CUC) is more urgent and complex due to the critical condition of the disease,which is often combined with uncontrollable massive hemorrhage,toxic megacolon or colonic perforation.Therefore,higher requirements for surgical and perioperative management are necessary.At present,when surgeons face CUC patients,what surgical strategy should be adopted is still lack of unified standard.The authors intended to sort out the timing,operation procedure and postoperative management of CUC so as to give full play to the value of surgical treatment and to improve the prognosis of CUC patients.

Surgery for ulcerative colitis in the era of biological agents therapy / 中华消化外科杂志

Ulcerative colitis is an inflammatory disease of colon and rectum whose etiology is still unclear.Infliximab is an anti-tumor necrosis factor antibody,which has been approved recently by the United States FDA for the treatment of ulcerative colitis to reduce signs and symptoms,to induce clinical remission and healing of the intestinal mucosa.Total proctocolectomy with pouch-anal anastomosis are the standard operation for ulcerative colitis now.The perioperative infliximab use,operation timing and procedures are the important factors affecting prognosis of patients in the era of infliximab therapy.

Analysis of complications of total proctocolectomy with ileal pouch-anal anastomosis in treatment of ulcerative colitis / 中华消化外科杂志

Objective To analyze the complications of total proctocolectomy with ileal pouch-anal anastomosis (TPC-IPAA) in treatment of severe or refractory ulcerative colitis (UC).Methods The retrospective cross-sectional study was conducted.The clinical data of 67 patients with severe or refractory UC who underwent TPC-IPAA in the Xinhua Hospital Affiliated to Shanghai Jiaotong University from February 2008 to October 2015 were collected.All the patients received open and laparoscopy-assisted TPC-IPAA,and two-stage or three-stage surgery was performed according to the patients' conditions.Observation indicators:(1) treatment and follow-up situations,(2) short-term complications after TPC-IPAA,(3) long-term complications after TPC-IPAA.The follow-up using telephone interview and outpatient examination was performed to detect the quality of postoperative life in patients and occurrence of complications up to July 2016.Measurement data with skewed distribution were described as M (range).The comparison of quality of pre-and post-operative life in patients was done using the paired t test.Results (1) Treatment and follow-up situations:all the 67 patients received successful surgery,including 45 with two-stage surgery and 22 with three-stage surgery.Thirty-seven patients underwent open surgery and 30 underwent laparoscopic surgery.The average frequency of postoperative daily defecation,average scores of quality of pre-and post-operative lifes were 5.6,0.47 and 0.67,respectively,with a statistically significant difference between preoperative indicators and postoperative indicators (t =-4.80,P ＜ 0.05).All the 67 patients were followed up for a median time of 4.6 years (range,1.0-8.4 years).(2) Short-term complications after TPC-IPAA:Of 67 patients,10 had short-term complications (some patients with multiple complications).One patient was complicated with presacral abscess secondary to sinus formation and then was cured by topical incision of sinus under colonoscopy.Five patients were complicated with anastomotic site-related complications of TPCIPAA,and 1 with pouch-anal anastomotic fistula combined with presacral abscess underwent drainage with ileostomy and didn't undergo stoma reversion of ileum.Two patients with fistula at the top of pouch were improved by surgery and repair.Of 2 patients with pouch-vagina fistula,1 underwent resection of pouch stump-vagina fistula and then were cured,and the space between pouch stump and posterior fornix was filled with a free greater omentum flap and temporary ileal bypass was simultaneously conducted.The other patient received twice transanal vaginal fistula repairs with advancement flap,and unclosed fistula was confirmed by angiography,with a clinical symptomatic relief.Eight patients with wound infection received actively dressing change after discharge,and no wound dehiscence was occurred.(3) Long-term complications after TPC-IPAA:28 of 67 patients had long-term complications.Twelve patients with intestinal obstruction underwent conservative treatments of gastrointestinal decompression,anti-inflammatory with corticosteroid and anti-infection with antibiotic,without the occurrence of severe intestinal perforation and prognosis needing surgical intervention,including 9 undergoing open TPC-IPAA and 3 undergoing laparoscopic TPC-IPAA.Thirteen patients with postoperative pouchitis received the conservative treatment of mesalazine.Three patients with failed pouch underwent small intestine permanent colostomy,including 2 with secondary pouch Crohn's disease and 1 with severe pouchitis.Conclusions TPC-IPAA is safe and effective in treatment of UC,with a lower incidence of complications.Anastomotic site-related complication of TPC-IPAA is the main short-term complication.And in the long-term complications,pouchitis is the most,followed it is intestine obstruction.

The postoperative complications and nursing experience of hand assisted laparoscopic J-type ileal pouch-anal anastomosis in familial adenomatous polyposis / 中国实用护理杂志

Objective To investigate the postoperative complication and nursing experience of hand-assisted laparoscopic J-type ileal pouch-anal anastomosis (IPAA) in familial adenomatous polyposis (FAP). Methods A total of 36 patients with FAP who had undergone hand-assisted laparoscopic J-type ileal pouch- anal anastomosis (IPAA) were analyzed retrospectively. Results The postoperative complication included ileal pouch bleeding in 2 cases, urinary retention in 3 female patients, external hemorrhoids swelling in 3 cases, and anastomotic fistula in 2 cases. Six cases had ileum pouch inflammation during the postoperative follow- up. All the complications were relieved after conservative medical therapy. Conclusions IPAA operation puts forward high technical requirements with more postoperative complications. Therefore, it is important to strengthen nursing of the patients, reduce postoperative complication and increase quality of life of FAP.

<b>A Case of Enterovaginal Fistula After Ileoanal Canal Anastomosis for Ulcerative Colitis Successfully Treated with Kampo Medicine </b> / 日本東洋医学雑誌

Enterovaginal fistula, which causes uncontrollable symptoms such as gas release, vaginal defecation, perineal erosion, and vaginitis, markedly reduces patients' quality of life. In this report, we present a case of successful treatment for enterovaginal fistula with Kampo medicine.<br>A 62 year-old female who had ileoanal canal anastomosis for ulcerative colitis developed symptoms of gas release and defecation from the vagina. Although these symptoms had disappeared with conventional medicine previously, they recurred 7 years later. There was no medical indication for surgery because the fistula could not be located by barium enema or endoscopic examination. She, therefore, visited our outpatient clinic 1 and a half years after all conventional management had ended in vain.<br>Her symptoms were slightly improved by the administration of ifutokaogi, a Kampo formula, although they persisted. Three months after switching her prescription to another Kampo formula, goreisan, her symptoms completely disappeared.<br>In recent years, there has been no report on goreisan for the successful treatment of enterovaginal fistulae. Our case suggests that Kampo medicine can be an option for the treatment of enterovaginal fistula refractory to conventional treatments.

Closure of leak at the tip of the "J" after ileal pouch-anal anastomosis using a novel over-the-scope clipping system / Fechamento de vazamento na extremidade de bolsa ileal em J após anastomose bolsa ileal-anal usando um novo sistema "over-the-scope" clip (OTSC)

OBJECTIVE: leaks from the body or the tip of the J-pouch can occur after restorative proctocolecotmy. Although it may follow an indolent clinical course, it often requires surgical repair or pouch revision. Here we describe a novel endoscopic approach to close the leak at the tip of the J pouch. DESIGN: pouchoscopy was performed under sedation and endoscopic over-the-scope clipping system was used for the management of a leak from the tip of a J-pouch. RESULTS: under sedation, a pouchoscopy was performed and the deep tip of "J" leak was detected with a guidewire, along with water-contrasted pouchogram. The contained cavity from the leak was cleaned with hydrogen peroxide and 50% dextrose. Debridement of the epithelialized mouth of the leak was performed with an endoscopic cytology brush. Then endoscopic over-the-scope clipping system was used and the leak defect was completely closed. There was no bleeding or perforation. The entire procedure took 25 min. The patient continued to do well and reported resolution of the low back pain symptom. CONCLUSION: we reported the first case in the literature that a leak from the tip of a J-pouch was endoscopically occluded using a novel over-the-scope clipping system. (AU)

OBJETIVE: vazamentos do corpo da bolsa e da extremidade da bolsa ileal em J podem ocorrer após proctocolectomia restauradora. Embora possam apresentar um curso clínico indolente, muitas vezes requerem procedimentos abdominais. DESENHO: endoscopia da bolsa ileal foi realizada sob sedação e clipagem endoscópica usando o sistema "over-the-scope" foi utilizada para fechar um vazamento na extremidade da bolsa ileal em "J". RESULTADOS: sob sedação, uma endoscopia de bolsa ileal foi realizada e a extremidade profunda do vazamento da bolsa ileal em "J" foi detectada com um fio-guia. A cavidade que continha o vazamento foi limpa com peróxido de hidrogênio e 50% de dextrose. Desbridamento da borda epitelizada do vazamento foi realizada com uma escova de citologia endoscópica. Então o sistema endoscópico "over-the-scope" clip foi usado e o vazamento foi completamente fechado. Não houve sangramento ou perfuração. O processo todo levou 25 minutos. O paciente evoluiu bem e relatou a resolução do sintoma de dor lombar. CONCLUSÃO: relatamos o primeiro caso na literatura de vazamento na extremidade de bolsa ileal em J que foi fechado através de procedimento endoscópico usando um novo sistema "over-the-scope" clip (OTSC).

Clinical value of hand-sewn ileal pouch anal anastomosis after proctocolectomy for the treatment of ulcerative colitis / 中华消化外科杂志

Objective To investigate the clinical value of hand-sewn ileal pouch anal anastomosis (HIPAA) for the treatment of ulcerative colitis.Methods The clinical data of 191 patients with ulcerative colitis who were admitted to the General Hospital of Tianjin Medical University from January 1989 to December 2013 were retrospectively analyzed.All the patients received proctocolectomy and open or laparoscopic HIPAA.Patients were followed up by questionnaire at postoperative month 3 and 12.The function of pouch was evaluated according to the defecation frequency per 24 hours and per night,Bristol scale stool form and Kirwan classification.The quality of life was assessed according to the Cleveland global quality of life (CGQL).Patients were followed up till April 2014.The independent samples were compared by t test,and data from multiple groups were compared by analysis of variance,pairwise comparison was done by LSD-t test,and the count data were analyzed using the chi-square test.Results Of the 191 patients,180 received open surgery and 11 received laparoscopic surgery.Nine patients were treated by one-stage surgery,175 by two-stage surgery and 7 by three-stage surgery.The pouches of 181 patients were J shape,9 were H shape and 1 was W shape.No patient died perioperatively.Eight patients had abdominal infection and 7 had incisional infection at early period after the operation,and they were cured by antibiotics.Four patients had pouch anastomotic bleeding and 4 had anastomotic leakage at postoperative week 1-2,and they were cured by local hemostasis or titanium clipping.Six patients had high intestinal obstruction,and they were alleviated by symptomatic treatment.Eight patients had inflammation of pouch,and they were alleviated by diet adjustment or antibiotics treatment.Two patients had sexual dysfunction.All the patients were followed up for 1-25 years.The function of the pouch was improved gradually.At postoperative month 12,the defecation frequencies were (3.7 ± 1.4)/24 hours and (1.3 ±0.5)/night,and the number of patients with type Ⅳ (Bristol classification),type Ⅴ,type Ⅵ and in grade Ⅰ (Kirwan classification),grade Ⅱ,grade Ⅲ were 107,76,8 and 177,8,6,respectively,which were significantly improved when compared with (6.5 ±2.8)/24 hours,(2.9 ± 1.5)/night,86,89,16 and 160,19,12 at postoperative month 3 (t =12.36,3.98,x2=7.76,29.27,P＜ 0.05).The CGQL indexes before operation and at postoperative month 3 and 12 were 0.37 ±0.19,0.67 ±0.16 and 0.82 ±0.13,respectively,with significant differences (F =6.011,P ＜0.05).There were significant differences between the CGQL indexes before operation and at postoperative 12 and 3 months (t =16.69,10.06,P ＜ 0.05).A significant difference was also observed between the CGQL indexes before operation and at postoperative 12 months (t =27.01,P ＜ 0.05).Conclusions HIPAA is suitable for the surgical treatment of ulcerative colitis.The function of the pouch is good and the quality of life is improved.

Quality of life in patients with ileal pouch for ulcerative colitis / Qualidade de vida em portadores de reservatório ileal por retocolite ulcerativa

INTRODUCTION: proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the standard surgical procedure for the treatment of ulcerative colitis (UC) and is associated with the prospect of cure. Experience gained over the years has demonstrated the occurrence of a high number of complications as well as bowel disorders that can compromise quality of life (QoL). OBJECTIVE: evaluate QoL in patients with IPAA for ulcerative colitis. PATIENTS AND METHODS: the Inflammatory Bowel Disease Questionnaire (IBDQ) was used to assess QoL in patients with IPAA after its validation in Portuguese. RESULTS: thirty-one patients submitted to IPAA by the same group of professionals were evaluated. QoL was classified as regular in all domains evaluated (intestinal and systemic symptoms and emotional and social aspects). There were no differences in relation to gender, type of pouch or postoperative time. However, elderly patients showed a tendency toward lower scores. Having a professional activity was associated with higher scores in systemic symptoms and social aspects (p < 0.05). Patients with ileostomy showed lower values in the domains of systemic symptoms, emotional and social aspects (p <0.05). CONCLUSION: in all domains assessed, patients with IPAA for UC had QoL classified as regular. Ileostomy and lack of professional activity negatively influenced QoL. (AU)

OBJETIVO: Avaliar a qualidade de vida em portadores de RI por RCUI. PACIENTES E MÉTODOS: Foi empregado IBDQ, validado em português na avaliação da QoL em portadores de RI. RESULTADOS: Foram avaliados 31 pacientes submetidos a RI pelo mesmo grupo. QoL foi classificada como regular em todos os domínios avaliados (sintomas intestinais e sistêmicos e aspectos emocionais e sociais). Não houve diferenças em relação ao sexo, tipo de reservatório ou tempo de pós-operatório. Entretanto, pacientes idosos apresentaram uma tendência a escores mais baixos. Atividade profissional relacionou-se com escores mais altos em sintomas sistêmicos e aspectos sociais (p < 0,05). Portadores de ileostomia apresentaram valores mais baixos nos domínios sintomas sistêmicos, aspectos emocionais e sociais (p < 0,05). CONCLUSÃO: Em todos os domínios avaliados, portadores de RI por RCUI apresentaram QoL classificada como regular. Ileostomia e inatividade profissional influenciaram negativamente a QoL. (AU)

The epidemiological and clinical features of familial adenomatous polyposis in Ribeirão Preto / Caracteristicas clínicas e epidemiológicas da polipose adenomatosa familiar em Ribeirão Preto

PURPOSE: to study 75 familial adenomatous polyposis (FAP) patients treated in a single institution in Ribeirão Preto/SP, from January 1981 to December 2011. METHODS: this is a retrospective study and the following data were collected: gender, age, main symptoms, familial history, coexisting malignancies, surgical treatment, surgical morbidity and mortality, factors related to life quality. RESULTS: median age was 29 years. Male-to-female ratio was 1.2:1. Bleeding was the most common symptom (62.6%). Colorectal cancer incidence was 25.5% (n = 19). Extracolonic neoplasia incidence was 8%. Colectomy with ileorectal anastomosis (IRA) was performed in 72% of the patients. Eighteen patients (24%) were submitted to proctocolectomy with "J-pouch" ileoanal anastomosis. In three patients (4%) proctocolectomy with terminal ileostomy was performed. Early and late complication rate were similar (22.7% × 24%). Ileal pouch surgery exhibited tendency to a higher morbidity and mortality but no significance could be found. Overall mortality rate was 7.46%. Malignant neoplasia was the main cause of mortality, accounting for 60% of deaths. CONCLUSION: FAP is a rare pathology in our country. Genetic counseling and proper screening programs are essential tools to early diagnosis and follow-up. Surgery is the most effective treatment and the best option to prevent malignant neoplasia. (AU)

OBJETIVO: analisar 75 pacientes com polipose adenomatosa familiar (PAF) tratados no Hospital das clínicas da Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo, entre janeiro de 1981 a dezembro de 2011. MATERIAIS E MÉTODOS: trata-se de estudo retrospectivo com coleta dos seguintes dados: sexo, idade, sintomas principais, história familiar, presença de malignidade, cirurgia realizada, morbidade e mortalidade cirúrgicas e fatores relacionados à qualidade de vida. RESULTADOS: a idade média encontrada foi de 29 anos. A razão entre os sexos foi de 1,2:1 com predomínio no sexo masculino. Sangramento intestinal foi o sintoma mais comum (62,7%). A incidência de câncer colorretal foi de 25,3% (n = 19). Neoplasias extracolônicas foram diagnosticadas em 8% dos pacientes. Colectomia total com íleo-reto anastomose (IRA) foi realizada em 72% (n = 54) dos pacientes. Proctocolectomia com anastomose ileoanal e bolsa ileal em "J" foi realizada em 24% (n = 18) dos casos e em 4% (n=3) dos pacientes optou-se pela proctocolectomia com ileostomia terminal (PCI). As taxas de complicações precoces e tardias foram semelhantes (22,7% × 24%). A cirurgia de bolsa ileal apresentou tendência a maior morbimortalidade, porém sem relevância estatística. A taxa geral de mortalidade foi de 7,46%. Neoplasias malignas foram responsáveis por 60% dos óbitos e complicações cirúrgicas por 40%. CONCLUSÕES: a PAF é uma patologia de baixa incidência no nosso país. O aconselhamento genético e o rastreamento familiar são instrumentos essenciais para o diagnóstico precoce e seguimento adequado. A cirurgia persiste como melhor opção para prevenção do câncer colorretal e tratamento da doença. (AU)

Endoscopic management of anastomotic bleeding in the ileal pouch with staples removal and clipping / Abordagem endoscópica do sangramento anastomótico da bolsa ileal com a remoção dos grampos e clipagem

OBJECTIVE: Postoperative pouch bleeding is a rare but detrimental complication following ileal pouch surgery. It is usually self-limited, however continuous bleeding requires intervention. There is limited published data on its management. DESIGN: Ileoscopy via stoma for loop ileostomy and pouchoscopy via anus for ileal pouch were performed under sedation for the purpose of diagnosis and management of postoperative bleeding. RESULTS: Ileoscopy demonstrated a large, long blood clot in the lumen of efferent limb, but no sign of active bleeding was identified. Pouchoscopy showed that lumen of pouch body as well as afferent limb was filled with maroon-colored liquid stool. Pouch and neo-terminal ileum mucosa was normal. Two dislodged staples at the anastomotic line with sharp tips towards the lumen were found, with activating bleeding at one site. The staples were removed by biopsy forceps, and active bleeding was successfully controlled by the deployment of one endoclip. CONCLUSIONS: We reported the first case that postoperative pouch bleeding, which was caused by dislodged staples, was successfully managed by endoscopic removal of the staples combined with clipping.

OBJETIVO: O sangramento pós-operatório da bolsa ileal é uma complicação rara, mas prejudicial após abordagem cirúrgica da bolsa ileal. Esse sangramento é geralmente autolimitado, porém, requer intervenção quando contínuo. Não há dados publicados sobre o tratamento. MÉTODO: Ileoscopia através de estoma para ileostomia em alça e endoscopia via ânus para a bolsa ileal foram realizadas sob sedação para diagnóstico e tratamento do sangramento pós-operatório. RESULTADOS: A ileoscopia demonstrou um grande e longo coágulo sanguíneo no lúmen do ramo eferente, mas nenhum sinal de sangramento ativo foi identificado. A endoscopia da bolsa ileal mostrou que os lumens do corpo da bolsa e ramo aferente estavam cheios de fezes líquidas de cor marrom. A bolsa e a mucosa do íleo neoterminal estavam normais. Dois grampos deslocados na linha da anastomose e com pontas afiadas em direção ao lúmen foram encontrados, com sangramento ativo em um dos locais. Os grampos foram removidos com pinça de biópsia e o sangramento ativo controlado com sucesso pela implantação de um endoclipe. CONCLUSÃO: Relatamos o primeiro caso em que o sangramento pós-operatório da bolsa ileal causado por grampos deslocados foi controlado com sucesso pela remoção endoscópica dos grampos combinada com clipagem.

Management of ileal pouch prolapse with endoscopic hot snare / Tratamento de prolapso da bolsa ileal com alca diatermica endoscopica

Pouch prolapse is a complication following the creation of restorative proctocolectomy. There is a paucity of information in the literature pertaining to its management. An ileal J pouch patient with dyschezia presented to our Pouch Center. Under sedation, pouchoscopy was performed with a gastroscope. We detected an anterior distal pouch mucosal prolapse, 1.5 cm in diameter, blocking the anal canal. The prolapsed mucosa was excised with hot snare under a retroflex view. There was no bleeding or perforation. The entire procedure took 25 minutes. The patient tolerated the procedure well and was discharged home 30 minutes after post-procedural observation. The patient reported the resolution of the dyschezia symptom. The histopathological examination of excised specimen showed small bowel mucosa and sub-mucosa with changes compatible with mucosal prolapse. Endoscopic hot snare appears to be feasible in the management of pouch mucosal prolapse. (AU)

O prolapso da bolsa ileal é uma complicação que pode surgir após a criação da proctocolectomia restauradora. As informações na literatura são escassas quanto ao tratamento. Um paciente com bolsa ileal em "J" e apresentando disquezia deu entrada em nosso centro médico. Sob sedação, realizamos uma endoscopia da bolsa ileal. Detectamos uma bolsa distal anterior com prolapso da mucosa, com 1,5 cm de diâmetro, bloqueando o canal anal. O prolapso da mucosa foi retirado com alça diatérmica sob visão retroflexa. Não houve sangramento ou perfuração. A duração de todo o processo foi de 25 minutos. O paciente tolerou bem o procedimento e recebeu alta após 30 minutos de observação pós-procedimento. O paciente relatou a resolução do sintoma de disquezia. O exame histopatológico do espécime extirpado mostrou a mucosa e submucosa do intestino delgado com alterações compatíveis com o prolapso da mucosa. A alça diatérmica endoscópica parece ser viável no tratamento de prolapso da mucosa da bolsa ileal. (AU)

Current trends regarding protective ileostomy after restorative proctocolectomy / Tendências atuais sobre ileostomia protetora após proctocolectomia restauradora

The decision to perform a protective ileostomy after ileoanal-pouch anastomosis is controversial, and most of the discussion is based on its advantages and disadvantages. Although a temporary intestinal diversion has been routinely indicated in most patients, this choice is also associated with complications. The present work aims to review the outcomes after restorative proctocolectomy with or without a protective ileostomy in the treatment of ulcerative colitis and polyposis syndromes. Most papers emphasize that diversion protects against anastomosis leaks; consequently, it may prevent pelvic sepsis and pouch failure. Otherwise, a defunctioning ileostomy may cause morbidity such as dehydration, electrolyte imbalance, psychological problems, skin irritation, anastomosis strictures and intestinal obstruction, among others. There are those who believe that the omission of an ileostomy after the confection of ileal pouches should be reserved for selected patients, with quite acceptable results. The selection criteria should include surgeon, patient and procedure features to ensure a good outcome. (AU)

A decisão de realizar ileostomia de proteção após anastomose da bolsa ileal ao canal anal é controversa, sendo a discussão baseada em suas vantagens e desvantagens. Embora a derivação intestinal temporária tenha sido indicada rotineiramente na maioria dos pacientes, essa escolha também está associada a complicações. O presente trabalho teve como objetivo rever os resultados após proctocolectomia restauradora com ou sem ileostomia de proteção no tratamento da colite ulcerativa e síndromes polipoides. Muitos trabalhos enfatizam que a derivação protege contra fístulas anastomóticas; consequentemente, ela pode prevenir sepse pélvica e perda da bolsa. Por outro lado, a derivação por ileostomia pode ser causa de morbidade como desidratação, distúrbios eletrolíticos, problemas psicológicos, lesões dérmicas, estenose de anastomose e obstrução intestinal, entre outras. Há aqueles que acreditam que a omissão de ileostomia após a confecção de bolsa ileal deve ser reservada a pacientes selecionados, obtendo-se resultados aceitáveis. Os critérios de seleção devem incluir características do cirurgião, do paciente e do procedimento na tentativa de se obter bons resultados. (AU)

Histopathological evaluation and risk factors related to the development of pouchitis in patients with ileal pouches for ulcerative colitis

OBJECTIVE: Many changes in mucosal morphology are observed following ileal pouch construction, including colonic metaplasia and dysplasia. Additionally, one rare but potential complication is the development of adenocarcinoma of the reservoir. The aim of this study was to evaluate the most frequently observed histopathological changes in ileal pouches and to correlate these changes with potential risk factors for complications. METHODS: A total of 41 patients were enrolled in the study and divided into the following three groups: a non-pouchitis group (group 1) (n = 20; 8 males; mean age: 47.5 years) demonstrating optimal outcome; a pouchitis without antibiotics group (group 2) (n = 14; 4 males; mean age: 47 years), containing individuals with pouchitis who did not receive treatment with antibiotics; and a pouchitis plus antibiotics group (group 3) (n = 7; 3 males; mean age: 41 years), containing those patients with pouchitis who were administered antibiotics. Ileal pouch endoscopy was performed, and tissue biopsy samples were collected for histopathological analysis. RESULTS: Colonic metaplasia was found in 15 (36.6%) of the 41 patients evaluated; of these, five (25%) were from group 1, eight (57.1%) were from group 2, and two (28.6%) were from group 3. However, no correlation was established between the presence of metaplasia and pouchitis (p = 0.17). and no differences in mucosal atrophy or the degree of chronic or acute inflammation were observed between groups 1, 2, and 3 (p>0.45). Moreover, no dysplasia or neoplastic changes were detected. However, the degree of mucosal atrophy correlated well with the time of postoperative follow-up (p = 0.05). CONCLUSIONS: The degree of mucosal atrophy, the presence of colonic metaplasia, and the degree of acute or chronic inflammation do not appear to constitute risk factors for the development of pouchitis. Moreover, we observed that longer postoperative follow-up times were associated with greater degrees of mucosal atrophy.

Early postoperative and long-term oncological outcomes of laparoscopic treatment for patients with familial adenomatous polyposis / 대한외과학회지

PURPOSE: We evaluated the short- and long-term outcomes of laparoscopic total proctocolectomy with ileal pouch-anal anastomosis (TPC/IPAA) for treatment of familial adenomatous polyposis (FAP). Also, we assessed the oncologic outcomes in FAP patients with coexisting malignancy. METHODS: From August 1999 to September 2010, 43 FAP patients with or without coexisting malignancy underwent TPC/IPAA by a laparoscopic-assisted or hand-assisted laparoscopic surgery. RESULTS: The median age was 33 years (range, 18 to 58 years) at the time of operation. IPAA was performed by a hand-sewn method in 21 patients (48.8%). The median operative time was 300 minutes (range, 135 to 610 minutes), which reached a plateau after 22 operations. Early postoperative complications within 30 days occurred in 7 patients (16.3%) and long-term morbidity occurred in 15 patients (34.9%) including 6 (14.0%) with desmoid tumors and 3 (7.0%) who required operative treatment. Twenty-two patients (51.2%) were diagnosed with coexisting colorectal malignancy. The median follow-up was 58.5 months (range, 7.9 to 97.8 months). There was only 1 case of local recurrence in the pelvic cavity. No cases of adenocarcinoma at the residual rectal mucosa developed. 5-year disease-free survival rate for 22 patients who had coexisting malignancy was 86.5% and 5-year overall survival rate was 92.6%. Three patients died from pulmonary or hepatic metastasis. CONCLUSION: Laparoscopic TPC/IPAA in patients with FAP is feasible and offers favorable postoperative outcomes. It also delivered acceptable oncological outcomes in patients with coexisting malignancy. Therefore, laparoscopic TPC/IPAA may be a favorable treatment option for FAP.
