The combination of duodenal atresia (DA) with esophageal atresia with tracheoesophageal fistula (EA-TEF) is a rare pathology, the frequency of which ranges from 1% to 6% of all cases of EA. Surgical treatment of the DA+EA-TEF combination always causes significant difficulties, primarily in determining the timing and stages of surgical correction. Objective of the study: to evaluate the results of treatment with a combination of DA+EA-TEF to determine the effective tactics of surgical treatment. Materials and methods of research: a retrospective, nonrandomized, uncontrolled, multicenter study was carried out. The work is based on the results of treatment of 15 newborns – 6 (40%) boys, 9 (60%) girls with a combination of DA+EA-TEF, who were treated in clinics of 6 university centers for pediatric surgery in the Russian Federation in 2015–2021. Simultaneous operations (SIMOPs) were performed in 10 (60%) patients, two-stage operations (TO) – in 5 (40%) newborns. The following criteria were taken into account: the period of antenatal (weeks) and postnatal (days) of establishing the diagnosis of obstruction of the gastrointestinal tract (GIT), gestational age (weeks), birth weight (g), weight at the time of surgery (g), type of concomitant pathology , sequence and methods of surgical treatment, terms of complete enteral feeding (days), outcomes of operations and reasons for unsatisfactory outcomes. The average gestational age of children who underwent SIMOPs was 35.1 weeks. (Q1 – 31.5, Q3 – 39; Me – 37; SD – 5.1; min/max – 25–40; 95% CI: 31.1–39.0) versus 29.8 weeks. at DO (Q1 – 29, Q3 – 30.5; Me – 30; SD – 1.0; min/max – 28–31; 95% CI: 28.4–31.6) did not differ statistically significantly (р=0.083). The mean body mass values did not have statistically significant differences (p=0.081) and amounted to 2224 g (Q1 – 1410, Q3 – 2930; Me – 2665; SD – 890.8; min/max – 760–3260; 95% CI: 1556–2926) for SIMOPs, versus 1322 g (Q1 – 1165, Q3 – 1450; Me – 1380; SD – 196; min/max – 980–1450; 95% CI: 1078.4–16565) in the TO group. Results: the average duration of SIMOPs was on average 144.4 min (Q1 – 125, Q3 – 155; Me – 147.5; SD – 22; min/max – 120–190; 95% CI: 1321–159.3), TO – 147.0 (Q1 – 125, Q3 – 172; Me – 140; SD – 33.4; min/max – 120–205; 95% CI: 126–178.6). The sequence of surgical correction of defects in SIMOPs in 8 (53%) patients consisted of thoracotomy, ligation of the TEF, direct anastomosis of the esophagus and the imposition of duodeno-duodenoanstomosis (DDA). In one case, DDA was selected as the first operation, which was supplemented with Kader gastrostomy followed by thoracotomy, ligation of the TEF and anastomosis of the esophagus after elongation according to I. Livaditis. In one patient, after thoracotomy and ligation of the TEF in connection with an insurmountable diastasis of the esophagus, a cervical esophagostomy (CE), duodenojejunoanastomosis (DEA) and a gastrostomy according to Kader were applied. In a two-stage correction (TO), the first operation in 3 patients was DDA (20%), supplemented in one case (7%) with Kader gastrostomy, and the second stage after 2 days performed thoracotomy with the elimination of TEF and EA. In 2 (13%) newborns, the first stage was thoracotomy, elimination of TEF and EA, followed by imposition of DDA 2 days later. In one case, due to an insurmountable diastasis of the esophagus after thoracotomy and ligation of the TEF, intrathoracic elongation of the esophagus according to Foker with delayed anastomosis of the esophagus (on the 7th day) and laparoscopic fundoplication according to Nissen (at 5 months) were performed. The duration of hospitalization did not statistically significantly depend on the chosen method for correcting the combination of DA+EA-TEF (p=0.79) and averaged 28.4 days for SIMOPs (Q1 – 16, Q3 –34.5; Me – 26; SD – 21.4; min/max – 5.0–79; 95% CI: 17.6–42.4), and for TOs – 27,2 days (Q1 – 21, Q3 – 33; Me – 28; SD – 7.1; min/max – 19–38; 95% CI: 27.2–33). In the group of patients with SIMOPs, 2 deaths (13%) were recorded on the 5th and 7th days after surgery due to progressive multiple organ failure and intractable pulmonary hypertension. In one case (7%), a lethal outcome was recorded 8 months after primary surgery due to progressive cardiovascular failure. Early postoperative mortality after SIMOPs was 20%, overall mortality was 30%. In the TO group, 3 (20%) deaths were recorded: 2 in the early postoperative period (on day 3 and day 19) and one at the age of 3 months of life. Early postoperative mortality after TO was 40%, overall mortality – 60%. Conclusion: it is preferable to choose the ligation of the TEF as the first operation and, if the child's condition allows, to impose an esophageal anastomosis and restore duodenal patency, followed by a nasogastric tube through the esophageal anastomosis into the stomach. If, after ligation of the TEF, the patient's cardiorespiratory status does not stabilize, it is possible to restore the patency of the esophagus and pass the probe into the stomach without imposing a gastrostomy, which will allow the patient to be further treated as an isolated DA, and the operation to restore the patency of the duodenum is delayed. In the presence of insurmountable diastasis, the use of esophageal elongation technology with subsequent delayed EA is justified.
