Pregnancy, delivery, and breastfeeding after total gastrectomy for gastric cancer: a case report

BACKGROUND: The reports of pregnancy after total gastrectomy for gastric cancer are rare. CASE PRESENTATION: We report a case of a 35-year-old woman, gravida 0, para 0, who became pregnant and delivered a baby 2 years and 6 months after laparoscopic-assisted total gastrectomy for early gastric cancer. Postoperatively, she showed a good progress during the follow-up and was continuously taking oral iron supplement and administered with methylcobalamin intramuscular injection. Two years after gastrectomy, she became pregnant. During the pregnancy, she kept taking iron and vitamin B(12) supplementation and had a good course of pregnancy and a normal delivery. However, 2 months after the delivery, liver dysfunction was detected via blood examination. The patient switched from exclusive breastfeeding to combined feeding with formula, and her laboratory results returned to normal. During 10 years of follow-up after the delivery, the patient was in good condition without any recurrence and nutritional deficiencies, and her child had thrived. CONCLUSIONS: Careful monitoring and management of iron and vitamin deficiencies are essential during pregnancy and the lactation periods for patients who previously underwent total gastrectomy. During the lactation period, a combination of formula and breastfeeding provides maternal and fetal nutritional support.
