Institutional report - Esophagus A surgeon's case volume of oesophagectomy for cancer does not influence patient outcome in a high volume hospital

c Abstract The aim of this study is to assess if individual case volume of oesophageal resections influences the operative mortality rate in a high volume hospital. Between June 1994 and June 2006, 252 total thoracic oesophageal resections (75% male, mean age 63 years) were performed by five surgeons in tertiary referral centre. Operative approach was standardised in all cases and consisted of left thoracolaparotomy, resection of all intrathoracic and abdominal oesophagus and left cervical incision for anastomosis. Operative mortality, defined as in-hospital death irrespective of length of stay, was compared among consultants and also trainees. A total of 207 operations were performed by five consultants with nine deaths (4.3%) compared to two deaths after 45 operations by 17 trainees (4.4%) wFisher's exact test, Ps0.61 (CIs0.84-1.26)x. Individual case volume for consultants ranged from 5 to 10.5 casesyyears wx -test, Ps0.34 (CIs0.89- 2 1.29)x with 0-5.4% mortality rate wx -test, Ps0.24 (CIs0.96-1.19)x. Overall hospital volume ranged from 17 to 57 casesyyears. This study 2
