In univariate analysis, uLAR and a low tumor location from the anal verge
were significant risk factors of weight loss after 3 years (p = 0.003 and 0.02, respectively; Table 3).
The following parameters were examined: continuous parameters (distance of the tumor from the anal verge
, age, duration of operation), dichotomous parameters (gender, type of anastomosis (CSA vs.
The distance from the distal flange of the stent to the anal verge
ranged from 15 to 20 cm.
The inferior border was placed 2 cm below the anal verge
or 2 cm below visible tumour if the tumour protruded from the anal canal.
The level of the primary tumor within the rectum was calculated mostly by rigid proctoscopy and/or digital rectal examination and expressed as the distance from the anal verge
. Low rectum was defined as 0-5 cm from the anal verge
, mid-rectum as 6-10 cm and high rectum as 11-15 cm.
Through the anterior puncture in front of the anus, 5-10 ml solution is then infiltrated subdermally on each side at the level of the anal verge
to secure superficial analgesia.
Miles Jones stated that the bruise on Trentadue's anal verge
was most likely the result of Trentadue having been kicked.
In most cases, the diagnosis can be made by visual inspection of the anal verge
with the patient in the prone jackknife position.
Anal canal length is determined by measuring the point at which the anal canal pressure suddenly rises higher than basal rectal tone to the point where it drops again suddenly (at or near the anal verge
Surgical method, level of anastomosis from the anal verge
, use of defunctioning stoma, duration of surgery (minutes), and blood transfusions utilized in the surgery were recorded.
The anaesthetic mixture was deposited in the sphincter complex approximately 3 cm from the anal verge
through the anococcygeal ligament into the ischiorectal fossae to the level of levator ani muscle.
Rectal exploration demonstrated the FB 6 cm proximally from the anal verge
. An abdominal X-ray was performed, giving details about object's characteristics: a long silicone penis, reaching the splenic flexure (Figure 1).
