RESUMO

BACKGROUND: Available techniques for IPAA in ulcerative colitis include handsewn, double-stapled, and single-stapled anastomoses. There are controversies, indications, and different outcomes regarding these techniques. OBJECTIVE: To describe technical details, indications, and outcomes of 3 specific types of anastomoses in restorative proctocolectomy. DATA SOURCE: Systematic literature review for articles in the PubMed database according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. STUDY SELECTION: Studies describing outcomes of the 3 different types of anastomoses, during pouch surgery, in patients undergoing restorative proctocolectomy for ulcerative colitis. INTERVENTION: IPAA technique. MAIN OUTCOME MEASURES: Postoperative outcomes (anastomotic leaks, overall complication rates, and pouch function). RESULTS: Twenty-one studies were initially included: 6 studies exclusively on single-stapled IPAA, 2 exclusively on double-stapled IPAA, 6 studies comparing single-stapled to double-stapled techniques, 6 comparing double-stapled to handsewn IPAA, and 1 comprising single-stapled to handsewn IPAA. Thirty-seven studies were added according to authors' discretion as complementary evidence. Between 1990 and 2015, most studies were related to double-stapled IPAA, either only analyzing the results of this technique or comparing it with the handsewn technique. Studies published after 2015 were mostly related to transanal approaches to proctectomy for IPAA, in which a single-stapled anastomosis was introduced instead of the double-stapled anastomosis, with some studies comparing both techniques. LIMITATIONS: A low number of studies with handsewn IPAA technique and a large number of studies added at authors' discretion were the limitations of this strudy. CONCLUSIONS: Handsewn IPAA should be considered if a mucosectomy is performed for dysplasia or cancer in the low rectum or, possibly, for re-do surgery. Double-stapled IPAA has been more widely adopted for its simplicity and for the advantage of preserving the anal transition zone, having lower complications, and having adequate pouch function. The single-stapled IPAA offers a more natural design, is feasible, and is associated with reasonable outcomes compared to double-stapled anastomosis. See video from symposium.

RESUMO

BACKGROUND: Proctocolectomy with ileal reservoir is the surgical procedure of choice for patients with ulcerative colitis and familial adenomatous polyposis. OBJECTIVES: To evaluate long-term postoperative complications (1994-2019) in patients operated for familial adenomatous polyposis (FAP) and ulcerative colitis (UC) and the degree of satisfaction with the procedure. METHODS: Observational study based on the analysis of a retrospective database with prospective follow-up in 115 consecutive patients: 79 with UC and 36 with FAP. A total of 88 patients were followed up, 60 with UC and 28 with PFA. RESULTS: 48 males (54.4%) with a mean age of 44.8 ± 10.6 years were evaluated. Indications for surgery were intractable disease in 54 patients (47%), dysplasia/cancer in 43 (37%), severe bleeding in 4 (4%) and perforation in 3 (3%). A proctectomy and mucosectomy of the rectal stump was performed in 67 (76.1%), and a double stapling technique in 21. A protective ileostomy was performed in all patients with UC and FAP. No differences were found in early complications between the two groups. Late complications showed a higher rate of reservoritis in UC patients compared to FAP (44.9 vs. 14.3%, p = 0.001), with more refractory reservoritis in the UC group (13.3 vs. 0%, p = 0.04) with no differences in bowel obstruction, strictures, or anastomotic fistulas. Overall satisfaction and adaptation were considered good in 87% of UC patients and only 57% in the FAP group (p < 0.01). CONCLUSIONS: Proctocolectomy with ileal reservoir has comparable morbidity and mortality, except for the higher rate of reservoritis in patients with a history of UC, despite this contingency there is a better quality of life and greater acceptance of surgery in UC patients than in FAP patients.

RESUMO

PURPOSE: This study compared outcomes after laparoscopic (LAP) or conventional (open) total proctocolectomy with outcomes after ileal J-pouch anal anastomosis (IPAA) at a single institution. METHODS: Charts from 133 familial adenomatous polyposis patients (1997-2013) were reviewed. Demographic data (age, sex, color, American Society of Anesthesiologists [ASA] status, previous surgery, and body mass index) and surgical outcomes (length of stay, early and late morbidity, reoperation, and mortality rates) were compared among 63 patients undergoing IPAA. RESULTS: Demographic features were similar among patients (25 open and 38 LAP). Conversely, colorectal cancer at diagnosis prevailed in the open group (60% versus 31.6%; P = .02). Tumor stages (P = .65) and previous surgery index (20% versus 10.5%; P = .46) were similar. Surgical length was longer for LAP (374 versus 281 minutes, P = .003). Short-term complication rates (28% versus 28.9%), hospital stay (10.9 versus 8.9 days), and total long-term reoperations (28% versus 21%) were not statistically different. However, major late morbidity (16% versus 2.6%; P < .001) and late reoperation rates (16% versus 5.2%; P < .05) were greater among open patients. Both groups did not differ regarding pouch failure rates (8% versus 5.2%). There was no operative mortality in the present series. CONCLUSIONS: (1) LAP IPAA is a safe procedure associated with a low conversion rate, (2) short-term results showed no clear advantages for both approaches, and (3) a greater risk of major late complications and late reoperations should be expected after open procedures.

RESUMO

BACKGROUND: Pouchitis is the most common complication of proctocolectomy with ileo-pouch-anal anastomosis (IPAA) for ulcerative colitis (UC). No previous study in Mexico has evaluated this issue; our aim was to evaluate its frequency, clinical characteristics and factors associated with its presence in Mexican patients with UC and IPAA. METHODS: Retrospective-cohort study including 70 patients with histopathological diagnosis of UC and IPAA between 1983 and 2014 from inflammatory bowel disease clinic of a tertiary care center. The statistical analysis used descriptive statistics, chi-square and Fisher's exact test for categorical variables and Student's t test for numeric variables. Univariate analysis was performed to identify the factors associated. RESULTS: Patients presenting with pouchitis accounted for 48.6%. From the 34 cases, 12 (35.3%) had inactive pouchitis; 7 (20.6%) active acute pouchitis; 15 (44.1%) chronic active pouchitis. On average, pouchitis occurred 5.37 years after IPPA. Factors probably associated with its occurrence were the presence of autoimmune concomitant diseases (ACDs; p = 0.06, OR 4.40, 95% CI 0.84-22.9) and extra-intestinal manifestations (EIMs; p = 0.05, OR 2.53, 95% CI 0.96-6.64), which was also probably associated with chronic active pouchitis (p = 0.06, OR 0.31, 95% CI 0.07-1.31). CONCLUSIONS: The frequency of pouchitis is high in Mexican UC patients after IPAA. ACDs and EIMs were probably associated with its development.

RESUMO

Background: Ulcerative colitis patients who underwent restorative proctocolectomy with ileal pouch-anal anastomosis can develop various mechanical complications. Among them is presacral sinus resulting from chronic anastomotic leak. Methods: We present a symptomatic patient with a large fecalith blocking the sinus which was successfully treated with Doppler ultrasound guided endoscopic needle knife sinusotomy along with fecalith extraction. Results: A 67-year-old female presented with a 4-month history of perianal pain and urgency. Pouchocopy showed a 3-cm deep wide-mouthed anastomotic sinus, the orifice of which was blocked by a large hard fecalith. Removal of the fecalith using RothNet, Tripod, or Basket were made but failed. Then needle knife was applied to cut the orifice to enlarge the opening of the sinus. One month later, the patient returned and the fecalith was successfully removed with two Baskets and two Rothnets. Six months after fecalith extraction, pouchoscopy showed a compartalized distal pouch sinus with two cavities, which was treated by two sessions of Doppler ultrasound guided endoscopic needle knife sinusotomy. Six months following the treatment, the sinus was completed healed. The patient tolerated all procedures well without any complication. Conclusion: Fecalith blocking pouch anastomotic sinus is a rare complication in patients with restorative proctocolectomy. In our case, this surgical complication was successfully treated with a carefully planned, stepwise endoscopy approach. (AU)

Experiênria: Pacientes com colite ulcerativa tratados por proctocolectomia restauradora com anastomose bolsa ileal-anal podem ser acometidos por diversas complicações mecânicas. Entre elas, cita-se o seio pré-sacral resultante de vazamento crônico pela anastomose. Métodos: Apresentamos uma paciente sintomática com um grande fecálito bloqueando o seio, com tratamento bem-sucedido com sinusotomia por bisturi-agulha guiado por ultrassom, juntamente com a extração do fecálito. Resultados: Mulher, 67 anos, apresentou-se com história de 4 meses de dor perianal e urgência. A avaliação endoscópica da bolsa ileal revelou um seio anastomótico com grande abertura situada a 3 cm de profundidade, cujo orifício estava bloqueado por um grande fecálito endurecido. Foi tentada sem sucesso a remoção do fecálito com a ajuda de Roth-Net, Tripod, ou cestos recuperadores. Depois dessas tentativas, aplicamos um bisturi-agulha com o objetivo de seccionar o orifício com vistas à ampliação da abertura do seio. Um mês depois, a paciente retornou, e o fecálito foi removido com sucesso com dois cestos recuperadores e dois RothNets. Transcorridos seis meses após a remoção do fecálito, uma avaliação endoscópica da bolsa ileal revelou um seio distal compartimentado com duas cavidades, tratado por duas sessões de sinusotomia endoscópica por bisturi-agulha guiado por ultrassom. Seis meses depois do tratamento, o seio estava completamente curado. A paciente tolerou satisfatoriamente todos os procedimentos, sem qualquer complicação. Conclusão: A presença de um fecálito bloqueando o seio anastomótico de bolsa ileal é complicação rara em pacientes submetidos a uma proctocolectomia restauradora. Em nosso caso, essa complicação cirúrgica foi tratada com sucesso com uma abordagem endoscópica em etapas, cuidadosamente planejada. (AU)

RESUMO

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).

RESUMO

PURPOSES: We retrospectively assessed our experience with the W-shaped orthotopic ileal pouch, which was constructed with non-absorbable titanium staples. For these purpose, we discuss the results of bladder capacity, urinary continence and early and long-term postoperative complications. MATERIALS AND METHODS: We included in the study 17 patients who underwent radical cystoprostatectomy followed by construction of an orthotopic W-shaped ileal pouch between October 2000 and November 2009. A 65-70 cm segment of ileum was isolated and prearranged into a W-configuration, leaving two 10 cm intact segments on both sides of the ileal fragment. In our technique we entirely anatomized all adjacent limbs in order to create a sphere-shaped pouch. The ureters were directly anastomized to both intact segments of the ileal division. All our patients underwent pouchscopy 6 months after operation and annually. RESULTS: Mean operative time for neobladder reconstruction and ureteral anastomoses was 87 ± 7.67 minutes. In one patient a leak from the ileo-ileal anastomosis was confirmed on the 3rd day after operation. In 2 cases unilateral stricture of the ureteral-neobladder anastomosis was documented. Staple lines were mostly covered with ileal mucosa after 6 months. The mean functional bladder capacity was 340 ± 27.6 mL and 375 ± 43.4 mL at 6 and 12 months, respectively. First-year daytime and nighttime continence was good and acceptable in 90% and 78% of patients, while it increased to 95% during the 2nd year. CONCLUSIONS: The long term follow-up shows that non-absorbable titanium staples can be safely used for creation of an orthotopic ileal neobladder. However, these data should be further validated in a larger series of patients.

RESUMO

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)
