Restorative proctocolectomy with ileal pouch-anal anastomosis in elderly patients - is advanced age a contraindication?

AIM: We aimed to determine pouch function and retention rate for restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC) in elderly patients. METHODS: We identified patients over 50 years old subjected to IPAA for confirmed pathological UC from 1980 until 2016. Patients were grouped according to age: 50-59, 60-69 and 70+ years. Short and long-term outcomes and quality of life (QOL) were compared among the groups. RESULTS: Six hundred and one patients were identified (399 (66.4%) between 50-59 181 (30.1%) between 60-69, and 21 (3.5%) over 70 years of age). More males were in the 70+ arm, and more two-stage procedures were performed in this group. Wound infection increased with age (P = 0.023). There was a trend of more fistula and pouchitis in the 70+ patients (P = 0.052 and P = 0.055, respectively). Pouch failure rate increased with age, and it was statistically significant in the 70+ cohort (P = 0.015). Multivariate stepwise logistic regression showed that pelvic sepsis (HR 4.8 (95% CI 1.5-15.4), P = 0.009), fistula (HR 6.0 (95% CI 1.7-21.5), and mucosectomy with handsewn anastomosis (HR 4.5 (95% CI 1.4-14.7)), were independently associated with pouch failure. No difference was observed in the QOL among the groups, but pouch function was better for patients younger than 60 years. CONCLUSION: In elderly patients with UC, IPAA may be offered with reasonable functional outcomes, and ileal pouch retention rates, as an alternative to the permanent stoma. Stapled anastomosis increases the chance of pouch retention and should be recommended as long as the distal rectum does not carry dysplasia.

Serum zinc, selenium, copper, and lead levels in women with second-trimester induced abortion resulting from neural tube defects: a preliminary study.

Neural tube defects are important causes of infant mortality and childhood morbidity. We investigated the relationship between zinc, selenium, copper, and lead concentrations and neural-tube-defect occurrence in women with a second-trimester termination due to fetal-neural-tube defects (NTDs) in this case-control study. Fourteen pregnant women whose pregnancies were terminated as a result of second-trimester ultrasonographic diagnosis of neural tube defects were recruited as cases. The control group (n = 14) consisted of women who were selected among age-, gravidity-, and socio-economic-state (SES)-matched women who had a normal triple-screen and targeted ultrasound during the second trimester with documented normal fetal outcome. Zinc and copper determinations were made using flame atomic absorption spectrophotometer (AAS). Graphite furnace AAS was used for Pb, and Se levels were measured with hydride generation AAS. Cases had significantly low serum zinc and selenium levels (62.48+/-15.9 vs 102.6+/-23.7 and 55.16+/-11.3 vs 77.4+/-5.5, respectively, p<0.001). Serum Cu and whole-blood Pb levels were significantly high when compared to controls. There was a negative correlation between serum zinc and selenium levels, and serum copper levels (r=-425 and -0.443, p<0.05). Our results are consistent with some previous reports. The etiology of NTDs cannot be explained with one strict etiologic mechanism. On the contrary, an interaction among environmental, genetic, and nutritional factors such as trace elements and vitamins would explain these anomalies. If folic acid supplementation is given, additional Zn supplementation should be considered for the further decrease in the recurrence and occurrence of NTDs.
