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.展开更多

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.展开更多

T...Familial adenomatous polyposis (FAP) is an autosomal dominant inherited syndrome characterized by multiple adenomatous polyps (predisposing to colorectal cancer development) and numerous extracolonic manifestations. The underlying genetic burden generates variable clinical features that may influence operative management. As a precancerous hereditary condition, the rationale of performing a prophylactic surgery is a mainstay of FAP management. The purpose of the present paper is to bring up many controversial aspects regarding surgical treatment for FAP, and to discuss the results and perspectives of the operative choices and approaches. Preferably, the decision-making process should not be limited to the conventional confrontation of pros and cons of ileorectal anastomosis or restorative proctocolectomy. A wide discussion with the patient may evaluate issues such as age, genotype, family history, sphincter function, the presence or risk of desmoid disease, potential complications of each procedure and chances of postoperative surveillance. Therefore, the definition of the best moment and the choice of appropriate procedure constitute an individual decision that must take into consideration patient’s preferences and full information about the complex nature of the disease. All these facts reinforce the idea that FAP patients should be managed by experienced surgeons working in specialized centers to achieve the best immediate and long-term results.展开更多

The standard procedure is restorativeproctocolectomy (RPC) with ileal pouch-anal anastomosis, commonly performedas two- or three-stage RPC with diverting ileostomy. Postoperative stoma outletobstruction (SOO) is frequent, but the causes are not well known.AIM To identify the risk factors for SOO after stoma surgery in patients with UC.METHODS We retrospectively reviewed the files of 148 consecutive UC patients whounderwent surgery with stoma construction. SOO was defined as small bowelobstruction symptoms and intestinal dilatation just below the penetrating part ofthe stoma on computed tomography. Patients were divided into two groups:Those who developed SOO within 30 d after surgery and those who did not.Patient characteristics, intraoperative parameters, the stoma site, and rectusabdominis muscle thickness were collected. Moreover, we identified the patientswho repeatedly developed SOO. Univariate and multivariate analyses wereperformed to identify risk factors for SOO and recurring SOO.RESULTS Eighty-nine patients who underwent two-stage RPC were included betweenJanuary 2008 and March 2020. Postoperatively, SOO occurred in 25 (16.9%)patients after a median time of 9 d (range 2-26). Compared to patients withoutSOO, patients with SOO had a significantly higher rate of malignant tumors ordysplasia (36.0% vs 17.1%, P = 0.032), lower total glucocorticoid dose one monthbefore surgery (0 mg vs 0 mg, P = 0.026), higher preoperative total protein level(6.8 g/dL vs 6.3 g/dL, P = 0.048), higher rate of loop ileostomy (88.0% vs 55.3%, P= 0.002), and higher maximum stoma drainage volume (2300 mL vs 1690 mL, P =0.004). Loop ileostomy (OR = 6.361;95%CI 1.322–30.611;P = 0.021) and maximumstoma drainage volume (OR = 1.000;95%CI 1.000–1.001;P = 0.015) wereconfirmed as independent risk factors for SOO. Eighteen patients with SOO weretreated conservatively without recurrence (sSOO group). Seven (28.0%) patientsrepeatedly developed SOO (rSOO group) during the observation period. Asignificant difference was observed in the rectus abdominis muscle thicknessbetween the two groups (sSOO 9.3 mm, rSOO 12.7 mm, P = 0.006). Musclethickness was confirmed as an independent risk factor for recurring SOO (OR =2.676;95%CI 1.176-4.300;P = 0.008).CONCLUSION In this study, high maximum stoma drainage volume and loop ileostomy areindependent risk factors for SOO. Additionally, among patients with a thickrectus abdominis muscle, the risk of SOO recurrence is high.展开更多

Virtually, all surgically untreated patients with FAP inevitably develop colorectal-cancer in their lifetime because they carry the adenomatous polyposis coli gene. Thus prophylactic proctocolectomy is indicated. Surgical treatment of FAP is still controversial. There are however, four surgical options: ileorectal anastomosis, restorative proctocolectomy with ileal pouch-anal anastomosis, proctocolectomy with ileostomy, and proctocolectomy with continent-ileostomy. Conventional proctocolectomy options largely lie between colectomy with ileorectal anastomosis or ileal pouch-anal anastomosis. Detractors of ileal pouch-anal anastomosis prefer ileorectal anastomosis because of better functional results and quality of life. The functional outcome of total colectomy with ileorectal anastomosis is undoubtedly far superior to that of the ileoanal pouch;however, the risk for rectal cancer is increased by 30%. Even after mucosectomy, inadvertent small mucosal residual islands remain. These residual islands carry the potential for the development of subsequent malignancy. We reviewed the literature (1975-2012) on the incidence, nature, and possible etiology of subsequent ileal-pouch and anal transit zone adenocarcinoma after prophylactic surgery procedure for FAP. To date there are 24 studies reporting 92 pouch-related cancers;15 case reports, 4 prospective and 5 retrospective studies. Twenty three of 92 cancers (25%) developed in the pouch mucosa and 69 (75%) in anal transit zone (ATZ). Current recommendation for pouch surveillance and treatment are presented. Data suggest lifetime surveillance of these patients.展开更多
