GLENDA: The ITEC Gynecologic Laparoscopy Endometriosis Dataset

GLENDA (Gynecologic Laparoscopy ENdometriosis DAtaset) comprises over 25 000 images taken from 400+ gynecologic laparoscopy surgeries and is purposefully created to be utilized for a variety of automatic content analysis problems in the context of Endometriosis recognition.

Endometriosis

Endometriosis is a benign but potentially painful condition among women in child bearing age involving the growth of uterine-like tissue in locations outside of the uterus. Corresponding lesions can be found in various positions and severities, often in multiple instances per patient requiring a physician to determine its extent. This most frequently is accomplished by calculating its magnitude via utilizing the combination of two popular classification systems, the revised American Society for Reproductive Medicine (rASRM) and the European Enzian scores. Endometriosis can not reliably identified by laymen, therefore, the dataset has been created with the help of medical experts in the field of endometriosis treatment.

Purposes

Overview

The dataset includes region-based annotations of 4 pathological endometriosis categories as well as non pathological counter example images. Annotations are created for single video frames that may be part of larger sequences comprising several consecutive frames (all showing the annotated condition). Frames can contain multiple annotations, potentially of different categories. Each single annotation is exported as a binary image (similar to below examples, albeit one image per annotation).

Categories

Example class frames with associated annotations, including original/annotated images with a representative sample video sequence for the category.

Peritoneum

As one of the most frequently diagnosed types, peritoneal endometriosis is found on the peritoneum, i.e. the lining of the abdominal cavity, which occurs in a mixture of red, yellow and white colors.

Ovary

Endometriosis is as well very frequently found on ovaries, the outer capsule of which appears in a shade of white.

Uterus

Uterine endometriosis or adenomyosis thickens the organ, which typically is colored in a red-tint.

Deep infiltrating endometriosis (DIE)

Non-shallow endometriosis that is found on specific locations such as the rectum, the rectovaginal space or uterine ligaments is described as Deep Infil- trating Endometriosis (DIE). Due to the variety of involved locations no distinct visual appearance can be attributed to this type of class, other than highlighting that typically the color spectrum in recorded laparascopic videos lacks green tones.

No pathology

Video sequences containing no visible pathology in relation to endometriosis are included in the dataset, providing counter examples to above categories. Since this class does not contain any region-based annotations, in addition to a sequence showing a non-pathological uterus, below listing particularly includes examples of several anatomical structures from above pathological classes (e.g. peritoneum and ovaries). Again it is not possible to make any assumptions about the color and shape of objects within this class, since it includes images covering most areas of the pelvic region.
