The colon or stomach is generally used for extended oesophagoplasty. These pediculated plasties may be complicated by necrosis or stenosis and require total or partial resection at a later stage. We report such an outcome in this case report: failure of left coloplasty, partial failure of right coloplasty and stomach then rendered unusable. The cervico-thoracic oesophagus was reconstructed using a free revascularised small bowel transplant, re-establishing the continuity between the cervical oesophagus and the retrosternal right colon. This case presents several particularities: semi-emergency salvage procedure, use of a saphenous vein graft to revascularise the intestinal artery using the lingual artery as nutrient artery, venous drainage of the transplant via the intrathoracic left brachiocephalic vein, necessity for resection of the left half of the manubrium sterni and the head of the left clavicle.
Between March 1982 and December 1987, 112 patients with oesophageal cancer were treated by gastroplasty following oesophagectomy to restore gastrointestinal continuity. This technique was used in all oesophageal cancers regardless of their site, with the exception of paryngo-oesophageal and oesophago-cardio-fundal cancers. The overall mortality of 12.5% fell to below 6% during the last two years. The postoperative course was straightforward in 54.5% of cases. The most frequent complications were respiratory tract complications (19 cases of ARDS out of 112 patients, i.e. 17%) and fistulae at the oesophago-gastric anastomosis (9 cases out of 112, i.e. 8%). The secondary complications were dominated by anastomotic stenoses (19/98, i.e. 19.3%).

Gastric oesophagoplasty (GOP) after total oesophagectomy or circular pharyngolaryngectomy is complicated by an average anastomotic breakdown or fistula rate of 15%, and a stenosis rate of 8%. Ischemia related to the actual procedure itself undoubtedly plays a role in the production of such complications in spite of the rich vascular supply to the stomach. The authors report the results of an anatomical study involving 24 stomachs from non-embalmed adults studied by various forms of arteriography depending in the GOP technique employed. For healthy normotensive gastric arteries, they demonstrate the principal elements likely to influence the vascularisation of the graft and propose a provisional vascular score for ischemia. Based on this, they discuss the vascular risks associated with GOP techniques in general.

Oesophagoplasty from colon and jejunum to exclude the stomach from digestive passage is a cause of Dumping syndrome. Severe postprandial hypoglycaemia occurred, after the stomach had been re-included into food passage. An analysis was made of the behaviour of carbohydrate metabolism and of the humoral factors associated with disorders.
