Does transthoracic compared to transhiatal resection alter the early postoperative course of oesophagectomy?

Abstract

SUMMARY. Several techniques for esophageal resections have been reported. However, clear clinical evidence is still lacking whether any of the procedures is superior to the others regarding morbidity and mortality in the early postoperative period. Two operative approaches for esophageal carcinoma, transhiatal and transthoracic, were compared with respect to operative morbidity, mortality and systemic inflammatory response. In our prospective study between 2000 and 2002 83 patients were investigated. In a retrospective post hoc analysis patients were divided into two groups due to the performed operational procedure, transhiatal (TH) or transthoracic (TT). Multiple Organ Dysfunction Score (MODS) was monitored daily (t1,t2,t 3). Serum procalcitonin (PCT) levels were determined on admission to the ICU (t0), then 24 hourly (t24,t48,t 72). Microalbuminuria (M:Cr) was measured before (tp), and after surgery (t0,t6,t24,t48,t 72). For statistical analysis Wilcoxon rank sum test, Mann-Whitney U-test and chi-square test were used as appropriate. We examined 52 patients in the TH group, and 31 patients in the TT group. There was no significant difference between the two groups regarding age, male/female ratio, and SAPS II scores. Operations lasted significantly longer in the TT group: 375 (300-480) min compared to the TH group 240 375 (180-319) min, P < 0.001. ICU mortality was similar in both groups (TH: 46 survivors/6 non-survivors; TT: 27 survivors/4 non-survivors; P = 0.607, respectively). Daily MODS did not differ significantly between the two groups. The observed inflammatory markers (PCT and M:Cr) followed the pattern we described earlier, without significant difference. In this study there was no difference in the clinical and biochemical variables of the patients between the transthoracic and transhiatal groups. The observed early postoperative morbidity and mortality may indicate, that both procedures can be considered as procedures with similar postoperative risk. © 2005 ISDE.
