[Surgical complications of esophageal resections: our experience with 168 operations].

: We performed 346 operations for oesophageal cancer between 1 June 1991 and 31 May 2001. 168 of them were resections. The resection rate was 48.5 percent. The most frequently performed operation was subtotal resection of the oesophagus with the removal of paraesophageal lymph nodes. Reconstruction was usually performed with gastric tube pulled up retrosternally according to Akiyama with cervical oesophago-gastrostomy (135/168). In 24 patients intrathoracic oesophago-gastrostomy and in 9 patients other type of reconstruction was performed. Considerable co-morbidity was present in 88 percent of our patients (148/168). Alcohol dependency was noted in 88 patients however we suspect there were patients who did not admit alcohol abuse. Extended resection i.e. other organs' resection together with the oesophagus was performed in 59 patients. Postoperative recovery was uneventful in 49.4 percent (83/168) of our patients. Surgical complications occurred in 28.6 percent. Anastomotic leak was observed in 21 cases (12.5 percent). The most severe complication was necrosis of an organ used in reconstruction (7 patients, 4.2 percent). 23 patients (13.7 percent) died in the postoperative period, 7 of them (4.2 percent) because of surgical complication. Statistical analysis proved that the R status and the extension of resection had no influence on the frequency of complications and mortality rate except for when the removal of the entire stomach or gastric stump was performed in one sitting with the oesophageal resection. The frequency of anastomotic leakage is grossly affected by the anastomosis technique and whether it was in cervical or in thoracic position.
