Collis-Nissen gastroplasty for short oesophagus.

The Collis-Nissen procedure is performed for the surgical treatment of 'true short oesophagus'. When this condition is strongly suspected radiologically, the patient is placed in the 45° left lateral position on the operating table with the left chest and arm lifted to perform a thoracostomy in the V-VI space, posterior to the axillary line. The hiatus is opened and the distal oesophagus is widely mobilized. With intraoperative endoscopy, the position of the oesophago-gastric junction in relationship to the hiatus is determined and the measurement of the length of the intra-abdominal oesophagus is performed to decide either to carry out a standard anti-reflux procedure or to lengthen the oesophagus. If the oesophagus is irreversibly short ('true short oesophagus'), the short gastric vessels are divided and the gastric fundus is mobilized. An endostapler is introduced into the left chest. The left thoracoscopic approach is suitable to control effectively the otherwise blind passage of the endostapler into the mediastinum and upper abdomen (if a second optic is not used). The tip of the stapler is clearly visible while 'walking' on the left diaphragm. The Collis gastroplasty is performed over a 46 Maloney bougie. A floppy Nissen fundoplication and the hiatoplasty complete the procedure.
