- Three-stage Laparoscopic Ileal Pouch-anal Anastomosis Is the Best Approach for High-risk Patients with Inflammatory Bowel Disease: An Analysis of 185 Consecutive Patients(2016) MEGE, D.; FIGUEIREDO, M. N.; MANCEAU, G.; MAGGIORI, L.; BOUHNIK, Y.; PANIS, Y.There are very few studies and no consensus concerning the choice between two- and three-stage ileal pouch-anal anastomosis [IPAA] in inflammatory bowel diseases [IBD]. This study aimed to compare operative results between both surgical procedures. Only patients who underwent a laparoscopic IPAA for IBD were included. They were divided into two groups: two-stage [IPAA and stoma closure] [Group A] and three-stage IPAA [subtotal colectomy, IPAA, stoma closure] [Group B]. From 2000 to 2015, 185 patients (107 men, median age of 42 [range, 15-78] years) were divided into Groups A [n = 82] and B [n = 103]. Patients in Group B were younger than in Group A (39 [15-78] vs 43 [16-74] years; p = 0.019), presented more frequently with Crohn's disease [16% vs 5%; p < 0.04], and were more frequently operated in emergency for acute colitis [37% vs 1%; p < 0.0001]. Cumulative operative time and length of stay were significantly longer in Group B (580 [300-900] min, and 19 [13-60] days) than in Group A (290 [145-490] min and 10 [7-47] days; p < 0.0001). Cumulative postoperative morbidity, delay for stoma closure, and function were similar between the two groups. Long-term morbidity was similar between Group A [13%] and Group B [21%; p = 0.18]. Our study suggested that postoperative morbidity was similar between two- and three-stage laparoscopic IPAA. It suggested that the three-stage procedure is probably safer for high-risk patients [ie in acute colitis].
- Desmoid tumors: clinical features and outcome of an unpredictable and challenging manifestation of familial adenomatous polyposis(2015) CAMPOS, Fabio Guilherme; MARTINEZ, Carlos Augusto Real; NOVAES, Marleny; NAHAS, Sergio Carlos; CECCONELLO, IvanBackground/Aims Desmoid tumors (DTs) are rare, locally invasive neoplasms that may affect 10-25 % of familial adenomatous polyposis (FAP) patients. Our aim was to evaluate incidence and clinical presentation among our patients, the potential impact on FAP outcome and to discuss treatment. Materials and methods Charts from 133 FAP (1977-2013) were reviewed. Patients with DTs were separated to retrieve demographic, clinical and management data. Follow-up was focused on disease evolution causing complications or death. Results 19 (14.3 %) DTs were diagnosed, either after previous trauma (16) or during FAP surgery (3). This group comprised 8 men (42.1 %) and 11 women (57.9 %) with an average age of 32.9 years. Intervals from surgical trauma to DTs ranged from 7 to 60 months. ECMs were detected in 12 (63.1 %) patients. DTs were located in the abdominal wall (8), abdominal cavity (8), abdominal wall and cavity (2) and left arm (1). Five patients (26.3 %) referred family history of DTs. Patients presented severe complications such as small bowel obstruction (4) and hydronephrosis (2), being directly responsible for death in three patients. Conclusions (1) DTs developed in 14.3 % of FAP, mostly after surgical trauma; (2) 30 % caused severe morbidity; (3) identification of clinical risk factors may help surgeons to develop screening and therapeutic decisions.
- Current evidence for universal molecular testing for colorectal cancer patients(2017) CAMPOS, Fábio Guilherme; FIGUEIREDO, Marleny Novaes; MARTINEZ, Carlos Augusto RealAbstract Background Risk assessment for Lynch Syndrome may be a complex and challenging task. Demonstration of germline mutations has the benefits of confirming Lynch Syndrome diagnosis and may also provide screening and surgical orientation for affected members and relief for non-affected relatives. Objective The present paper aimed to critically review the criteria to diagnose Lynch Syndrome, focusing the attention on the new perspective of adopting universal screening for patients diagnosed with colorectal cancer. Methods We performed a literature review about the rationale and preliminary results of universal testing for Lynch Syndrome. Results The use of selective eligibility criteria to determine who should undergo Lynch Syndrome testing may fail in a substantial proportion of cases. Moreover, universal strategy is feasible, cost-effective and more sensitive than previous methods. However, there still exist problems regarding clinical practice implementation and compliance either by medical doctors and patients. Conclusions Standard guidelines for colorectal cancer screening are not ideal to provide early detection of Lynch Syndrome patients. And although universal screening has been associated with an increased identification of Lynch Syndrome patients, a successful implementation of this approach is still limited by the lack of clinical expertise among physicians, and also requires standardization of the existing protocols for routine genetic screening.
