Abstract.

Colon interposition is an established technique for esophageal reconstruction. We describe the case of primary adenocarcinoma arising in a colonic interposition graft that was performed after total esophagectomy for recurrence adenocarcinoma derived from the Barrett esophagus.

1. Introduction

In 1911, Kelling and Vuillet described the anatomic and surgical bases for the use of colon as replacement for the esophagus [1, 2].

Early postoperative complications are common, including necrosis of the transplant, leaks, fistulae, and strictures at the anastomoses. Late complications are rare. We describe an unusual late complication of a primary adenocarcinoma arising in the interposed colon after a right colonic bypass in a patient with adenocarcinoma derived from the Barrett esophagus.

2. Case Report

A 66-year-old male presented with history of progressive dysphagia for solid food.

Six years ago, he underwent a proximal gastrectomy and distal esophagectomy for adenocarcinoma derived from Barrett esophagus. Four years later, an esophagoscopy revealed a recurrence at the anastomotic site. A biopsy of the lesion showed a well-differentiated adenocarcinoma of the esophagus. Further investigation showed no evidence of metastatic disease, and a three-stage procedure with total esophagectomy was performed. The right-sided colon from the ileocaecal junction to the mid-transverse colon was used in a prevertebral position to reestablish continuity between the cervical esophagus and the remnant of the pyloric antrum. Histological examination revealed a pT2N0 lesion, and the patient recovered well without major complications. Two years after this intervention, the patient developed a progressive dysphagia for solid food. Endoscopy showed a circumferential mass arising from the colon (Figure 1), and biopsy confirmed a colonic type of adenocarcinoma. Barium swallow revealed the circumferential tumor at the ileocaecal junction (Figure 2). Further investigation with PET scan (Figure 3) demonstrated a tumor paravertebral right at the level of D7–D9 and no metastatic disease. Reintervention was proposed to the patient. Through a right thoracotomy an ileocaecal resection with end-to-end anastomosis was performed with preservation of the “cardial” marginal arcades artery to prevent necrosis of the proximal ileal segment.

Figure 1: The PET-CT showed a tumor paravertebral right at the level of D7–D9 and no metastatic disease.

Figure 2: Barium swallow revealed a circumferential mass arising from the colon.

Figure 3: Endoscopy showed circumferential tumor at the ileocaecal junction.

Histological examination revealed a pT2 tumor of the colon and one normal lymphenode.

The patient recovered well with a good functional conduit and remained disease-free now at 24 months.

3. Discussion

The potential use of a pedicled segment of colon to bypass esophageal pathology was first described since the early sixthies. Colonic grafts have been used in the treatment of both benign (e.g., esophageal atresia and stricture) and malignant oesophageal pathology (e.g., cancer of esophagus and cardia).

Early complications of this procedure are common, including graft necrosis, anastomotic leak, fistulae, and stricture of the anastomosis [3–5]. Other unusual sequelae, including paracolic hiatal herniation and herniation of small intestine through the mesocolon have been reported [6].

Late complications are rare: progressive fibrostenosis of the graft, peptic colitis with ulceration of the colonic segment, gastrocolic reflux, and colopericardial and colobronchial fistula were described [4, 7]. The progressive development of diverticular disease in colon interposition has also been reported in previous literature by Nelson and Grayer [8].

Primary carcinoma arising in a colonic interposition is obviously rare. Review of literature showed only 11 cases (Table 1). These cases describe the use of colonic grafts in the treatment of both benign (e.g., esophageal atresia and stricture) and malignant oesophageal pathology (e.g., cancer of esophagus and cardia). Table 2 shows the pathology in the colonic graft at long term and the treatment.

The late development of dysphagia in a patient with a colonic interposition graft should be examined seriously.

Contrast studies of colonic grafts can be difficult to interpret due to altered anatomy. Barium esophagography has the advantage of providing functional evaluation of the graft and integrity of the conduit anastomosis. However, radiographic evaluations and interpretations of the interposed colon may be difficult if there is unfamiliarity with the various surgical procedures and the postoperative appearances [10, 11].

Endoscopy with biopsy should therefore be considered.

Computed tomography plays a limited role in the examination of the interposed colon. It may provide valuable evaluation of the extent of the tumor invasion and for the staging preoperatively.

So far, there is no definable association between the primary carcinoma of the esophagus or stomach and the colon cancer [20, 21].

As more patients are followed over a long period, the later sequelae of colon interposition will become more evident. Whether the interposed segment of colon is more likely to develop carcinoma than a normally sited segment of colon remains to be seen.

In our case, a pre-existing lesion of the colon was indeed missed: during the examinations preoperatively an existing little spot was not remarked on PET scan (Figure 4). This was probably a tubulovillous adenoma of the colon. It is clear that examination of the colon before using it as a graft to exclude colonic disease is preferred.

Figure 4: Pre-existing lesion of the colon missed on PET-CT.

On the other hand, to rule out the existence of a second primary cancer arising in the interposed colonic mucosa, an endoscopy of the colonic graft should be considered regularly as follow up in the postoperative period.

In summery, malignancy arising in the interposed colon graft is rare.

Total colonoscopy should be included in the preoperative setting when interposition of colonic segment needs to be used for replacement of the esophagus. This is to detect unexpected lesions.

Development of new symptoms in a patient with a colonic graft should always be taken seriously and investigated.
