Inclusion criteria

  • \< 35
  • Hinchey I-III

Exclusion criteria

Exclusion Criteria:

  • > 35
  • Hinchey IV
  • Previous procedures that could have been modified the nervous mesenteric pattern (surgery, radiotherapy or chemotherapy)
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

Study arms

  • Experimental
    Inferior mesenteric artery preservation

    Performing colorectal resection for diverticular disease the IMA was preserved ligating the sigmoids arteries close to colonic wall.

    Procedure: IMA preserving

  • Active comparator
    Inferior mesenteric ligation

    Performing colorectal resection the IMA was sectioned just below the origin of left colic artery.

    Procedure: IMA sectioning

Interventions

  • ProcedureIMA preserving

    Performing left hemicolectomy, sigmoidectomy or rectal resection the IMA was preserved ligating the sigmoids arteries close to the colonic wall

  • ProcedureIMA sectioning

    Performing left emicolectomy, sigmoidectomy or rectal resection the IMA is sectioned after the origin of left colic artery.

    Time frame: 12 months from surgery

  3. Constipation

    The incidence and severity of postoperative constipation was evaluated with Cleveland Clinic Constipation Score ( score range from 0 to 30, the higher score defines worse constipation status)

    Time frame: 6 years from surgery

  4. Incontinence

    The presence of fecal incontinence was evaluated with Cleveland Clinic Incontinence Score( score range from 0 to 20, the higher score defines worse symptoms)

    Time frame: 6 months from surgery

  5. Incontinence

    The presence of fecal incontinence was evaluated with Cleveland Clinic Incontinence Score( score range from 0 to 20, the higher score defines worse symptoms)

    Time frame: 12 months from surgery

  6. Incontinence

    The presence of fecal incontinence was evaluated with Cleveland Clinic Incontinence Score( score ranges from 0 to 20, the higher score defines worse symptoms)

    Time frame: 6 years from surgery

  7. Anorectal Muscles function

    The anorectal muscles function was evaluated with anorectal manometry( sphincter lenght, maximum squeeze pression, resting anal pressure, squeeze duration, maximum pressure sustained)

    Time frame: 6 months from surgery

  8. Anorectal Muscles function

    the anorectal muscles function was evaluated with anorectal manometry ( sphincter lenght, maximum squeeze pression, resting anal pressure, squeeze duration, maximum pressure sustained)

    Time frame: 6 years from surgery

  9. Postoperative quality of life

    the postoperative QOL(quality of life) was evaluated with EORTC-30 tests( European organization for research and treatment of cancer, scores range from 0 to 100; a higher score represents a higher ("better") level of functioning, or a higher ("worse") level of symptoms)

    Time frame: 6 months from surgery

  10. Postoperative quality of life

    the postoperative QOL was evaluated with EORTC-30 tests( European organization for research and treatment of cancer,scores range from 0 to 100; a higher score represents a higher "better" level of functioning, or a higher "worse" level of symptoms

    Time frame: 12 months from surgery

  11. Postoperative quality of life

    The postoperative QOL was evaluated with EORTC-30 tests( European organization for research and treatment of cancer,scores range from 0 to 100; a higher score represents a higher "better" level of functioning, or a higher "worse" level of symptoms)

    Time frame: 6 years from surgery

  12. Postoperative quality of life

    The postoperative QOL was evaluated with EORTC-29 tests (European organization for research and treatment of cancer each question goes from 1 to 4 , the higher score defines worse symptoms)

    Time frame: 12 months from surgery

  13. Postoperative quality of life

    The postoperative QOL was evaluated with EORTC-29 tests (European organization for research and treatment of cancer each question goes from 1 to 4 , the higher score defines worse symptoms)

    Time frame: 6 years from surgery

  14. Postoperative quality of life

    The postoperative QOL was evaluated with EORTC-29 tests (European organization for research and treatment of cancer each question goes from 1 to 4 , the higher score defines worse symptoms)

    Time frame: 6 months from surgery

  15. Postoperative quality of life

    The postoperative QOL(quality of life) was evaluated with SF-36 score (Short form-36 score, each item scored from 0 to 100, the higher scores defines a favorable health state)

    Time frame: 6 months from surgery

  16. Postoperative quality of life

    The postoperative QOL was evaluated with SF-36 score (Short form-36 score, each item scored from 0 to 100, the higher scores defines a favorable health state)

    Time frame: 12 months from surgery

  17. Postoperative quality of life

    The postoperative QOL was evaluated with SF-36 score (Short form-36 score, each item scored from 0 to 100, the higher scores defines a favorable health state)

    Time frame: 6 years from surgery

  18. Postoperative surgical complication

    The incidence of postoperative surgical complications was evaluated

    Time frame: 1 month from surgery

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2012 to primary completion in Jan 2024, 144 months.

Of 70 non-industry interventional studies with no phase under Fecal Incontinence, half reached primary completion within 36 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 57. This study's 144 months is above that.

Counting every sponsor, half of 86 studies reached it within 36 months; a quarter within 20 and three quarters within 57.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 23, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
