Long-term follow-up after retrosternal ileocolic esophagoplasty in two cases of long-gap esophageal atresia: why it is still a valid option as a rescue strategy

IntroductionEsophageal replacement surgery in children is sometimes necessary for long-gap esophageal atresia. Ileocolic esophagoplasty in the retrosternal space can serve as a good alternative technique in case of hostile posterior mediastinum. We present two cases of successful ileocolic transposition performed at 6 months of age.MethodsEsophageal replacement was performed through a midline laparotomy incision associated with a left cervical approach. The ileocolic transplant was pediculized on the right superior colic artery after ligating the right colic and ileocolic vessels. A retrosternal tunnel was created, and the ileocolic transplant pulled through it to reach the cervical region. Proximally, esophageal-ileal anastomosis and, distally, colonic–gastric anastomosis were performed. Ileocolic continuity was repaired.ResultsThere were no early postoperative complications. In both cases, the patients presented oral feeding difficulties during the first 6 postoperative months. Thereafter, full oral feeding was achieved, and both patients were clinically asymptomatic during the following 18 and 20 years, respectively, with satisfactory oral radiological assessments, showing no redundancy or inappropriate growth of the graft and no anastomotic stricture. Currently, these patients do not complain of dysphagia, pathological reflux, or respiratory symptoms.ConclusionWhen native esophagus preservation in long-gap esophageal atresia is estimated unfeasible, ileocolic transposition in the retrosternal space might be considered a good and safe option, particularly in those difficult cases after multiple previous surgical attempts and mediastinitis. This technique is putatively associated with a beneficial anti-reflux effect, thanks to the presence of the ileocecal valve, in preventing cervical peptic esophagitis. Long-term follow-up confirms that the transposed colon in the retrosternal space did not suffer any abnormal modification in size and growth.

Usefulness of Gastrojejunostomy Prior to Fundoplication in Severe Gastro-Esophageal Reflux Complicating Long-Gap Esophageal Atresia Repair: A Preliminary Study

Background: Gastro-esophageal reflux disease (GERD), requiring surgical correction, and nutritional problems are reported after long-gap esophageal atresia (LGEA) repair and might jeopardize the postoperative course in some babies. We report an exploratory evaluation of the role of transgastric jejunostomy (TGJ) as a temporary nutritional tool before surgery for GERD in LGEA. Methods: Seven infant patients operated on for LGEA with intra-thoracic gastro-esophageal junction (GEJ) and growth failure, requiring improvement in their nutritional profile in anticipation of surgery, were retrospectively evaluated. Post-surgical follow-up, including growth evolution, complications, and parental quality of life (QoL), were considered. Results: The TGJ was placed at a mean age of 8.6 ± 5.6 months. The procedure was uneventful and well-tolerated in all seven cases. At 6.6 ± 2.0 months after TGJ placement, significant weight gain (weight z-score −2.68 ± 0.8 vs −0.9 ± 0.2, p < 0.001) was recorded, allowing the GERD surgery to proceed. A significant difference in hospital admissions between 3 months before and post-TGJ insertion was noted (4.8 ± 0.75 vs. 1.6 ± 0.52, p < 0.01). A significant amelioration of QoL after TGJ placement was also recorded; in particular, the biggest improvements were related to parents’ perceptions of the general health and emotional state of their babies (p < 0.001). Conclusions: The placement of TGJ as a temporary nutritional tool in selected cases of LGEA could improve nutritional conditions and parental QoL before fundoplication, allowing successful surgical treatment of GERD to be carried out.

Type-A long-gap esophageal atresia treated by thoracoscopic esophagoesophagostomy after sequential extrathoracic esophageal elongation (Kimura’s technique)

We report four cases of long-gap esophageal atresia (LGEA) treated with thoracoscopic esophagoesophagostomy (TEE) after sequential extrathoracic esophageal elongation (SEEE: Kimura's technique). All initially had gastrostomy, then SEEE. The proximal end of the esophagus was introduced into the apex of the thorax under direct vision during TEE. Mean birth weight was 1.9 kg. Mean gestational age was 35.0 weeks (range 30-39); mean age at initial esophagostomy was 43.2 days (range 15-110); SEEE was performed for a mean of 3 times (range 2-4) at mean intervals of 5.3 months (range 2-10), with the upper esophageal segment lengthened by a mean of 2.1 cm each time (range 1.1-3.5). Mean age and weight at TEE were 22.3 months and 9.8 kg, respectively. Gap was initially 4.5 vertebrae (range 4-5). Mean operating time was 9.6 h. TEE was successful in 3; 1 required thoracotomy, then re-anastomosis after 11 months of anastomosis leakage; 2 cases with post-TEE anastomosis leakage were treated conservatively. Postoperatively, all cases required fundoplication and esophageal dilatation (2, 3, 5, 8 times, respectively). At mean follow-up of 3.6 years, 2 eat normally and 2 eat minced food. TEE after SEEE appears to be a feasible option for treating LGEA.

Repair of long-gap esophageal atresia: gastric conduits may improve outcome—a 20-year single center experience

IntroductionTreatment of long-gap esophageal atresia (LEA) is a major challenge. Options for reconstruction include native esophagus, or replacement with stomach, colon, or small intestine. However, debate continues regarding the optimal conduit for esophageal replacement.MethodsMedical records of patients with a diagnosis of esophageal atresia during a 20-year period were reviewed.ResultsTwenty-eight cases of LEA were identified. Ten patients underwent primary anastomosis either after serial pouch dilations (9/10) and/or after a lengthening procedure (2/10). Nine received colonic interpositions, and the remainder were reconstructed with a gastric tube (n = 3), or gastric interposition (n = 2). One patient died prior to repair, and two await definitive treatment. Repeat esophageal reconstruction was required in four patients because of conduit ischemia. Two ischemic events occurred in the colonic interposition group, and two in the native esophageal repairs. All patients, except one who relocated, received long-term follow-up (mean 4.2 years: range 0.5–11.5 years).ConclusionsSurgeon’s expertise and patient’s anatomy should be considered when selecting an appropriate operation for LEA. Although native esophagus is generally preferred, it is associated with a high rate of stricture. Although our study has a limited by numbers, we found that patients with gastric conduits had lower complication rates and no conduit ischemia. We suggest that gastric transposition may be favored as an initial reconstructive option.

Colon esophagoplasty in the orthotopic position

Three cases of long-gap esophageal atresia were repaired using a technique that included a right extrapleural thoracotomy, preservation of the entire esophagus available, both anastomoses in the mediastinum, use of a short segment of colon, and preservation of the ileocecal valve. This approach, not previously described, combines multiple features aimed at decreasing complications related to traditional techniques. Successful early results are promising.
