Intestinal transit time
The gastric, small intestinal and colonic mean transit times were significantly longer in women.
Ageing was shown to accelerate the gastric and small intestinal transit significantly.
In the group of men the colonic mean transit time was unaffected by age, but middle-aged women had a significantly slower colonic transit than young women.
Graff J, et al. Clin Physiol 2001 Mar;21(2):253-9
both age and gender have to be considered
when reference values for gastric, small
intestinal and colonic mean transit times
have to be established.
Conclusion
Intestinal transit time
Normal colonic transit time: 72 hours
Tt can be measured:
– Radioopaque markers study
– Scintigraphically

Colonic Constipation
Anorectal manometry
There is no uniform criteria for defining manometric abnormalities
No pathognomonic data
No differences between Colonic constipation and Outlet obstruction

possible aetiological factors of rectal

Constipation
Anorectal manometry
Rectal hyposensivity and sensory threshold volumes
elevated beyond the normal range:
– 33% of patients with rectocele
– 40% of rectal intussusception
– 53% of patients with no mechanical obstruction evident on
defecography.
SS Rao et al, Gastroenterologist 1996
This suggests that damage to the rectal wall can be associated
and not only consequent to rectal intussusception.!!!!!

Fifty patients (8 with slow transit constipation, 36
with obstructed defecation and 6 with mixed one)
have been dealt with biofeedback training:
The results were related to psychological state rather than anorectal tests.
70% of patients found biofeedback helpful and 62%
improved, irrespective of the type of constipation

Percutaneous tibial nerve stimulation for slow transit
constipation: a pilot study. Collins B, Norton C, Maeda Y. Colorectal Dis. 2012 14(4):165-70.
18 pts, (range 21-74) with slow transit constipation previously failing maximal
biofeedback therapy participated in the study.
12 sessions of 30 minutes of percutaneous tibial nerve stimulation.
constipation score improved significantly (median 18 pre-treatment,
range 10-24, to median 14 post-treatment, range 7-22; P = 0.003).
The PAC-QOL also showed significant improvement (median 2.31, range
1.36-3.61, to median 1.43, range 0.39-3.78; P = 0.008).
Stool frequency increased (P= 0.048) and the use of laxatives decreased
(P = 0.025).
There was no change in colonic transit time (P = 0.45).
CONCLUSION:
Percutaneous tibial n stimulation has potential as an affordable and
minimally invasive treatment for slow transit constipation.
Outcome of colectomy for slow-transit constipation in
relation to presence of small-bowel dysmotility
• the outcome of surgery was good or excellent in
7/7 patients with normal findings on antroduodenal
manometry
• only 5/9 patients with abnormal manometry
findings attained a good result after surgery.

Regression analysis revealed a significant correlation
between GIQLI and urgency and abdominal pain

Laparoscopic versus open colectomy for patients with American Society of
Anesthesiology (ASA) classifications 3 and 4: the minimally invasive approach
is associated with significantly quicker recovery and reduced costs. da Luz Moreira A, Kiran RP, Kirat HT, Remzi FH, Geisler DP, Church JM, Garofalo T, Fazio VW.
Surg Endosc. 2010 Jun;24(6):1280-6.
• Estimated blood loss, return of bowel function, length of
hospital stay, and total direct costs were decreased in the LC
group.
• Wound infection was significantly greater with OC (p = 0.02).
• When patients with previous major laparotomy were excluded,
the two groups had similar overall morbidity.
•LC is a safe option for pts with a high ASA classification.
•LC approach faster postop recovery, lower morbidity
rates, and lower hospital costs than the OC approach.
Total abdominal colectomy has a similar short-term outcome
profile regardless of indication: data from the National Surgical
Quality Improvement Program. Alves-Ferreira PC, et al. Am Surg. 2011;77(12):1613-8.
cConstipated pts had more neurologic and renal complications when
compared with the IBD group (P = 0.01).
NNone of the other categories of complications were statistically different
among the diagnosis groups.
uUrinary tract infection higher in the constipation pts vs IBD (10 vs 4%, P =
0.03), no statistically significant differences among the other short-term
specific complications.
TThe 30-day complication rate after TAC is similar for chronic
constipation, neoplasia, and IBD
