Background. Benign stenosis of the posterior anastomoses after colorectal surgery appears in 8 to 30% of the cases. Balloon dilatation is the current standard of treatment given it effectiveness and safety. Several dilatation techniques are available at the moment; we present here our experience with TTS hydrostatic dilatation balloon of 20 mm. and its short and long term follow up. Patients and Methods. Seven patients who presented with intestinal obstruction (total or partial) by benign stenosis of the colorectal anastomoses were selected and dilatation with of 20 mm hydrostatic TTS balloon under our protocol was performed. (90 PSI/6 ATM). All received one session and follow up was made to them (up to 67 months). Results. Balloon dilatation was successful in all the patients, remaining asymptomatic in short and long term follow up. One of the patients in whom an anastomotic leak appeared early after the surgery required two sessions of hydrostatic balloon dilatation and one session of pneumatic balloon dilatation because of recurrent stenosis. No complications were observed in the studied sample. Conclusions. TTS hydrostatic balloon dilatation is safe and effective in the treatment of benign stenosis of the anastomoses after colorectal surgery.
