Total laparoscopic hysterectomy: how does training for surgeons in a standardized operation affect hospitals and patients?

PurposeSurgical training usually means inexperienced physicians initially doing operations supervised by an experienced physician, to gain the experience and skills needed to conduct surgery independently. Various issues arise here for both hospitals and patients. Are training procedures associated with higher complication rates, blood losses, and transfusion rates? What does training in the operating room ultimately cost in terms of valuable surgical time? Do longer hospitalization periods potentially mean financial losses for the hospital under the diagnosis-related groups (DRG) system?MethodsA retrospective analysis was carried out of data for 571 patients who underwent total laparoscopic hysterectomy (TLH) in the Department of Gynecology at the University of Erlangen from 2009 to 2012, with/without adnexectomy, due to benign indication; and of data for 255 patients who underwent the same procedures in Karlsruhe Municipal Hospital in 2013-2014. The patients were classified into two groups: those in whom surgery was carried out by experienced specialists who had carried out at least 40 independent operations; and those in whom it was carried out by a trainee resident who had personally done fewer than 40 operations.ResultsIn the two groups, the patients had similar mean body mass indexes, uterus weights, and blood losses. Patients in the specialist group were slightly older. There were no differences in complication rates. Over two-thirds of complications occurred in patients with previous surgery. Procedures by residents took significantly longer. Hospitalization periods in both groups were still below the mean threshold length of stay under Germany's DRG system, so that no income losses occurred even with training procedures.ConclusionsTraining and teaching operations supervised by experienced surgeons are just as safe as operations by experienced surgeons themselves. Interpretation of these data is of course limited by the retrospective study design; patients treated by specialists tended to have more prior operations and were older, with a trend toward larger uteri. Surgical training, as the example of TLH in benign indication shows here, involves an additional time of approximately 10-20min per operation. With regard to the revenue situation, the hospitalization periods in both groups were within the profit zone for the hospital concerned.
