About

Description

Procedure category: Small bowel surgery - Incision, excision or anastomosis of small intestine, excluding procedures which involve anastomosis of small to large bowel.

Procedure subcategory: Open extirpation of lesion of duodenum (Clean-Contaminated) (G50)

Methodology

Generated programmatically from the Surgical Site Infection Surveillance Service (SSISS) Operating Procedure Codes Supplement (OPCS) under the UK Open Government Licence v3.0. This includes codelists for 17 categories of surgical procedure. Within each category, there are subcategories of procedures. This codelist includes the codes for a single subcategory.

These can be included in the surveillance using the following Y75 .codes as a secondary code to indicate the laparoscopic approach For example, a laparoscopic assisted closure of perforated ulcer of duodenum would be given a primary procedure code of G52.1 and a secondary code of Y75.1. Y75.1 Laparoscopically assisted approach to the abdominal cavity Y75.2 Laparoscopic approach to the abdominal cavity not elsewhere classified.

Codelists are developed by a broad community of users for individual study purposes, which may or may not meet the needs of other studies. They should not be thought of as universal definitions of a particular condition.

We don't offer any guarantees about what they do or don't identify. Users should carefully check that any codelist meets their needs, and seek clinical input where appropriate.
