Prevalence of Adenomas and Carcinomas in the Ileal Pouch After Proctocolectomy in Patients with Familial Adenomatous Polyposis

Purpose  Restorative proctocolectomy has become 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. Our aim was to evaluate the prevalence, nature, and etiology of ileal pouch and nonpouch adenomas and carcinoma in patients with FAP. Patients and methods  This was a retrospective study of 31 FAP patients with Kock’s continent ileostomy (Kock; n = 8), ileorectal anastomosis (IRA; n = 7), and ileal pouch–anal anastomosis (IPAA) (n = 16). All patients were followed with a standardized protocol including chromoendoscopy and biopsies of visible polyps in the ileal pouch and nonpouch mucosa. Results  Sixteen of 24 pouch patients (Kock and IPAA) developed adenomas in the ileal pouch mucosa, and all patients with IRA developed adenomas in the rectal mucosa. The prevalence of ileal adenomas was significantly higher in pouch patients than in IRA patients (P = 0.002). Only one patient with Kock showed adenoma in the prepouch area. Two cases of adenocarcinomas and one case of advanced adenoma were found in the ileal pouch mucosa. Conclusion  Our results show a high frequency of adenomas in the ileal pouch mucosa, with evolution into carcinoma in some patients. Regular endoscopic surveillance of the pouch is recommended at a frequency similar to that for the rectal mucosa after IRA in pouch patients with FAP.     

Laparoscope-Assisted Versus Conventional Restorative Proctocolectomy with Rectal Mucosectomy

To assess the advantages of a laparoscope-assisted proctocolectomy with ileal J-pouch anal anastomosis compared with conventional procedures, we retrospectively analyzed the results of the two procedures as follows: Eleven patients including five patients with familial adenomatous polyposis (FAP) and six with ulcerative colitis (UC) underwent a laparoscope-assisted proctocolectomy and hand-sewn ileal J-pouch anal anastomosis at our department from June 1997 to November 1999. This laparoscope-assisted colectomy (LAC) group was then compared with a group of 13 patients who had undergone conventional ileal pouch anal anastomosis using a standard laparotomy from 1986 to 1997. The median operative time of the LAC group was 8 h 23 min, which was 81 min longer than that of the standard colectomy (SC) group. The number of days during which eating was prohibited were similar in the two groups but the median postoperative hospital stay was significantly shorter in the LAC group (24.1 days). In the LAC group, the small incisions showed better cosmetic results and there was also a remarkable reduction in the degree of postoperative pain. In conclusion, a laparoscope-assisted proctocolectomy with ileal J-pouch anal anastomosis can be employed widely in patients with FAP and also in selected patients with UC.

家族性腺瘤性息肉病17例的诊断与外科治疗

目的：总结家庭性腺瘤性息肉病（FAP）的诊断和外科治疗经验。方法：回顾分析17例FAP的临床病理资料。结果：17例患者中男7例，女10例，平均年龄23．8岁，良性13例，平均年龄19．6岁，癌变4例，平均年龄37．8岁，13例有家庭史。家系调查发现1个家系至少有2例患者，最多可达7例，其中，6个家系中有7人已死于息肉癌变，全部患者均施行了全结肠切除，并分别采用回肠造口，回肠储袋，回肠肛管吻合等术式，随访2－20年，13例良性患者均存活。其中1例术后5年发生癌变，癌变者中1例术后5年发生肺部转移，行肺叶切除术后2年死亡，1例术后3年因广泛转移死亡，另2例为术后2年和6年，仍存活 。结论：FAP易癌变应尽早手术，手术宜选全结肠切除，直肠粘膜剥脱，回肠储袋，回肠肛管吻合术。     

直肠手术各种储袋的应用与评价

结肠储袋能改善低位直肠切除保肛术后早期控制排粪功能障碍,但其对患者术后远期（2年以上）控制排粪功能方面不具有优势。同时,随着时间的延长,排空障碍的发生率将逐渐提高,很多患者出现排粪困难,需要长期应用栓剂和灌肠。而储袋的制作延长了手术时间,增加了治疗费用。所以,低位直肠切除术后结肠储袋的价值正在遭受质疑,它的应用也变得越来越少。在溃疡性结肠炎（UC）和家族性腺瘤性息肉病（FAP）行全结肠切除术后,如果行回肠储袋肛管吻合（IPAA）,可通过增加新建直肠的容积并改变肠管的生理学动力,使排粪次数减少;且术后短期和长期控制排粪功能更好,生活质量更高。所以,IPAA是手术治疗UC和FAP的首选。     

Should ileal pouch–anal anastomosis include mucosectomy?

OBJECTIVE: Debate exists as to the benefits of performing mucosectomy as part of pouch surgery for ulcerative colitis (UC) and familial adenomatous polyposis (FAP). Whilst mucosectomy results in a more complete removal of diseased mucosa, this benefit may be at the price of poorer function. We examined these issues. METHOD: Using Medline, Embase, Ovid and Cochrane database searches papers were identified relating to the outcome following pouch surgery with and without mucosectomy. Potential reasons for functional problems were investigated, as were rates of 'cuffitis', dysplasia, polyposis and cancer in the ileal pouch and anal canal. RESULTS: The available evidence suggests that performing a mucosectomy leads to a worse functional outcome. Meta-analysis suggested that nighttime seepage of stool and resting and squeeze pressure were worse after mucosectomy. The most likely reason for functional impairment following pouch surgery was the degree of anal manipulation. Mucosectomy does seem to confer benefit in terms of disease control but this benefit does not reach statistical significance. CONCLUSION: Stapled anastomosis avoiding mucosectomy is the approach of choice for ileal pouch anal anastomosis because this leads to superior functional outcome. Performing mucosectomy results in some clinical benefits in terms of lower rates of inflammation and dysplasia in the retained mucosa in UC patients and lower rates of cuff polyposis in FAP patients. However, on the basis of available evidence mucosectomy is only indicated in those cases where the patient is at a high risk of disease in the retained rectal cuff.     

Rectal eversion and double-stapled ileal pouch anal anastomosis in familial adenomatous polyposis syndrome

INTRODUCTION

Surgery is the only treatment option for familial adenomatous polyposis (FAP). Aim of surgery in FAP is to minimize colorectal cancer risk without need for permanent stoma. There are especially two operation options; Total colectomy with ileorectal anastomosis (IRA) and total proctocolectomy with ileo-pouch anal anastomosis (IPAA). We report here a patient with FAP who had resection via rectal eversion just over the dentate line under direct visualization and ileoanal-J pouch anastomosis by double-stapler technique.

PRESENTATION OF CASE

A 40 yr. old female patient with FAP underwent surgery. Firstly, colon and the rectum mobilized completely, and then from the 10 cm. proximal to the ileo-caecal valve to the recto-sigmoid junction total colectomy was performed. Rectum was everted by a grasping forceps which was introduced through the anus and then resection was performed by a linear stapler just over the dentate line. A stapled J-shaped ileal reservoir construction followed by intraluminal stapler-facilitated ileoanal anastomosis. Follow up at six months anal sphincter function was found normal.

DISCUSSION

There is only surgical management option for FAP patients up to now. Total colectomy with IRA and restorative proctocolectomy with IPAA is surgical options for FAP patients that avoid the need for a permanent stoma. Anorectal eversion may be used in the surgical treatment of FAP, chronic ulcerative colitis and early stage distal rectal cancer patients.

CONCLUSION

J-pouch ileoanal anastomosis can safely be performed by rectal eversion and double stapler technique in FAP patients.     

Adenocarcinoma after ileoanal anastomosis for familial adenomatous polyposis: Review of risk factors and current surveillance apropos of a case

Restorative proctocolectomy has become the most common surgical option for familial adenomatous polyposis (FAP) patients, based on the premise that it provides good functional results and reduces colorectal cancer risk. But several adenomas may develop in the pouch mucosa over the years, and even cancer at the anastomosis or in the pouch mucosa has been reported rarely. This article aims to describe a case of pouch cancer after restorative proctocolectomy for FAP, reviewing the possible causes of this unfortunate outcome. A 40-year-old man started presenting with fecal blood loss 12 years after restorative proctocolectomy with mucosectomy and hand-sewn anastomosis for FAP. Proctologic examination revealed an elevated mass 3 cm from the anal margin, which biopsy determined to be a mucinous adenocarcinoma.Thepatient underwent pouch excisionand terminal ileostomy. Histologic analysisshowed a 2.2 cm mucinous adenocarcinoma between the ileal and anal mucosa (T2N0Mx) and multiple tubular microadenomas in the ileal pouch. The present case and the data presented here suggest that restorative proctocolectomy is not a "cancer-free" alternative to ileorectal anastomosis, because it does not remove the risk of metachronous intestinal neoplasia. Although the long-term risk of malignancy is not known, lifelong follow-up seems to be necessary after restorative proctocolectomy. Current recommendations for pouch surveillance are presented.     

Prevalence and risk factors for adenomas in the ileal pouch and the afferent loop after restorative proctocolectomy for patients with familial adenomatous polyposis

Background

Restorative proctocolectomy with ileal pouch–anal anastomosis (IPAA) has become the treatment of choice in familial adenomatous polyposis (FAP) to prevent the risk of colorectal cancer. However, it currently is recognized that adenomas may develop in the ileal pouch. The risk of adenoma occurring in the afferent ileal loop above the pouch is less clearly identified. This study aimed to evaluate the difference in prevalence of adenomas between the ileal pouch and the afferent ileum after IPAA in FAP.

Methods

The study analyzed 442 endoscopies performed between 2003 and 2008 for 139 FAP patients. The patients had undergone an IPAA in 118 cases, an ileorectal anastomosis in 13 cases, or an ileostomy in 8 cases.

Results

Among the 118 IPAA patients, 57 (48.3 %) had pouch adenomas a median of 15 years after surgery. The risk factors for pouch adenomas were delay since pouch construction [odds ratio (OR), 1.11; p = 0.016] and presence of advanced duodenal adenomas (OR, 4.35; p = 0.011). Seven patients had pouch adenomas with high-grade dysplasia. Only nine patients had afferent ileal loop adenomas (6.5 %). The only significant risk factor for ileal adenomas was the presence of pouch adenomas (OR, 2.16; p = 0.007).

Conclusion

After restorative proctocolectomy in FAP, adenoma recurrence is frequent in the pouch, with a higher risk for patients with advanced duodenal adenomas and an increasing risk over time, whereas adenomas are rarely found in the afferent ileal loop. This finding may help to propose redo ileal pouch anal anastomosis if required.
