During planning of an alternative laparoscopic entry site, the surgeon identifies a left paraumbilical point on a line drawn 2.5 cm medial to the anterior superior iliac spine. Which access point is this?
Question Stem
A) Palmer's point
B) Lee-Huang point
C) Jain point
D) Umbilical point
E) Hasson point
B) Lee-Huang point
C) Jain point
D) Umbilical point
E) Hasson point
Options
A
Palmer's point
B
Lee-Huang point
C
Jain point
D
Umbilical point
E
Hasson point
Explanation
The Jain point is described as a left lateral paraumbilical laparoscopic access site located on a line drawn 2.5 cm medial to the anterior superior iliac spine. The defining feature in this question is therefore its relationship to the left paraumbilical region and the anterior superior iliac spine. Palmer's point is situated 3 cm below the left subcostal margin in the midclavicular line. The Lee-Huang point lies midway between the xiphoid process and umbilicus in the middle upper abdomen. The umbilical point is the commonest standard Veress needle site, while Hasson refers to an open entry technique rather than a surface landmark defined by this relationship. The described anatomy therefore identifies the Jain point.
Option Validity
A) Palmer's point is defined by the left subcostal margin and midclavicular line.
B) Lee-Huang point lies midway between the xiphoid and umbilicus.
D) The standard umbilical point is not defined by its relationship to the anterior superior iliac spine.
E) Hasson describes an open entry technique rather than this named surface landmark.
