    Abstract:
    Operations were performed on 166 patients for adenocarcinoma of the cardia, between 1970 and 1986, with resections being applied to 102 of them (6.1 per cent), including 87 curative approaches with complete removal of tumours and no macroscopic evidence of metastases. Total gastrectomy with oesophagectomy was performed on 36 patients and proximal oesophagogastrectomy on 66, in 43 of these via left thoracic incision. Regional lymph nodes were free of tumour in 29 patients (28 per cent). The other approaches to proximal resection were thoracoabdominal in eight cases, abdominal in 13, and transmediastinal in two. Leakage of oesophageal anastomosis occurred in 19 cases and was followed by septicaemia and death in 13. Overall mortality during hospitalisation amounted to 22.5 per cent, including two patients who died on the 30th postoperative day as a result of dehiscence and septicaemia. Mortality figures were 17 per cent following total gastrectomy and 19 per cent in the wake of proximal gastrectomy by thoracic incision. Mortality amounted to 48 per cent in the 23 cases on which abdominal, thoraco-abdominal, and transmediastinal operations had been performed. Multiple logistic regression was used to determine age, ECG, spread of lymph nodes, and surgical techniques as potential risk factors. Emphasis in the context of surgical techniques was laid on proximal versus total gastrectomy, incision on both sides of the diaphragm, palliative resection, and anastomotic suturing (using one-layer or two-layer techniques or mechanical staples). Tumour spread to lymph nodes and proximal resection were the only independent variables associated with dehiscence. Electrocardiogram (ECG), lymph node involvement, and palliative resection proved to be of relevance to prognostication of lethality. No statistical correlations were found to exist between lethality, on the one hand, and surgical approach, age of patient, incision on either side of the diaphragm or suturing, on the other. The conclusion was drawn that in cases of cardia carcinoma total gastrectomy does not aggravate the risk of lethality, as compared to cardia resection.
