Background

There is no effective treatment for gastroesophageal anastomotic strictures that are refractory to repeated endoscopic balloon dilation (EBD). However, EBD is still selected worldwide to manage such refractory strictures. To relieve the symptoms of dysphagia and keep a wide lumen, we developed a new incisional treatment, radial incision and cutting (RIC).

Objective

To evaluate the efficacy and safety of the RIC method for the treatment of refractory anastomotic strictures.

Design

Retrospective cohort study.

Setting

National Cancer Center and University Hospital.

Patients

This study involved 54 consecutive patients with refractory anastomotic stricture after esophagogastric surgery.

Intervention

RIC.

Main Outcome Measurements

The safety and clinical success of RIC and the long-term patency after RIC compared with those of continued EBD.

Results

The median procedure time of RIC was 14 minutes (range, 4-40 minutes). No serious adverse events associated with RIC were observed. Immediately after RIC, 81.3 % (26/32) of patients were able to eat solid food without symptoms of dysphagia. As a short-term effect, the dysphagia improved after RIC in 93.8 % (30/32) of the patients. As a long-term effect, 63 % (17/27) and 62 % (13/21) of patients were able to eat solid food 6 and 12 months after RIC, respectively. The 6-month and 12-month patency rates were significantly different between the RIC group and the continued EBD group (65.3 % vs 19.8 % , P < .005; 61.5 % vs 19.8 % , P < .005).

Limitations

Nonrandomized retrospective study.

Conclusions

RIC is an effective and safe method. The demonstration of the validity of this method may place RIC as a new medical treatment for patients with refractory stricture after surgical resection for esophagogastric diseases.
