Objective. Surgery is one of the riskiest and most important medical acts that is performed today. Understanding the ways in which surgeries are similar or different from each other is of major interest. Desires to improve patient outcomes and surgeon training, and to reduce the costs of surgery, all motivate a better understanding of surgical practices. To facilitate this, surgeons have started recording the activities that are performed during surgery. New methods have to be developed to be able to make the most of this extremely rich and complex data. The objective of this work is to enable the simultaneous comparison of a set of surgeries, in order to be able to extract high-level information about surgical practices. Material and Method.We introduce Non-Linear Temporal Scaling (NLTS): a method to realign a set of surgeries along their intrinsic timeline. Experiments are carried out on a set of lumbar disc neurosurgeries. We assess our method both on a highly standardised phase of the surgery (closure) and on the whole surgery.Results. Experiments show that NLTS makes it possible to consistently derive standards of surgical practice and to understand differences between groups of surgeries.

NLTS realigns a set of sequences along their intrinsic timeline, which makes it possible to extract standards of surgical practices.Supplementary material.

“…Previous studies concentrated on analyzing surgical procedures, using task analysis to understand the complexities of procedures, with an aim to improve training systems [4,5,13,16]. Studies combining task analysis of procedures with error analysis have focused on surgical trainees, and thus have detected the skillbased errors that constitute the greater proportion of novice errors, implying targets for improved teaching of skills [10,12].…”

Sequence and task analysis of instrument use in common laparoscopic procedures

Abstract: This study demonstrated that laparoscopic instruments are often used to perform a variety of maneuvers in addition to their primary function. Furthermore, there are common patterns in instrument exchange that provide a potential source of design parameters for improved surgical efficiency.
