Deep infiltrating rectal endometriosis (DIRE)
represents an
advanced and particularly debilitating form of endometriosis, in
which lesions infiltrate the rectal wall. It is often associated with
severe
digestive symptoms (pain during defecation, constipation, diarrhea,
sub-obstructive syndrome) and
infertility. For women of reproductive age with a
desire for pregnancy,
surgical management becomes a major
therapeutic and
strategic challenge.
Among available options, segmental rectal
resection allows for complete removal of the affected area but involves a
more invasive procedure, potentially associated with postoperative functional
risks (bowel transit disorders, impaired anorectal function, urinary or sexual
complications). In contrast, conservative techniques such as shaving
(superficial lesion removal) or discoid resection (targeted excision of
infiltrated zones) aim to minimize complications while offering satisfactory
disease control, with the goal of preserving both fertility and quality of
life.
In this context, the
choice of surgical
technique raises important questions—especially for patients whose primary goal
is pregnancy.
This retrospective study assesses the
true
impact of these two surgical strategies on
pregnancy outcomes. It compares the
rates observed after radical surgery (segmental resection) versus conservative
surgery, with the aim of guiding therapeutic decisions based on patients’
reproductive goals.
Radical surgery or gentle approach: which wins
for fertility?
182 women with deep infiltrating rectal endometriosis who underwent surgery
between 2009 and 2019—and had a stated desire for pregnancy—were included in
the study:
- 109 underwent
segmental rectal resection,
- 73 had conservative
surgery (shaving or discoid resection).
A systematic two-year follow-up was conducted
after surgery, collecting data on
spontaneous pregnancies, use of
assisted
reproductive technologies (IVF, insemination), and
pregnancy outcomes (ongoing,
miscarriage, birth).
The goal was to
measure the overall pregnancy
rate (by any method) and assess whether the type of surgery had an impact on
postoperative fertility. The follow-up also aimed to document
postoperative
complications—especially digestive and urinary—that may affect quality of life
and the ability to pursue parenthood.
The results revealed no significant difference in fertility outcomes between the two groups.
The overall pregnancy rate was identical, reaching 61.5% in both groups,
with similar proportions of spontaneous pregnancies. However, conservative
surgery was associated with fewer severe postoperative complications,
suggesting a better safety profile without compromising conception rates.

Preserving the uterus without sacrificing the
chances?
Deep infiltrating rectal endometriosis is a severe form of the disease, often
responsible for intense digestive pain, reduced quality of life, and
infertility. Surgical treatment—often necessary—raises critical concerns for
women wishing to conceive.
The main challenge lies in the choice of
surgical approach: Should we opt for segmental resection, potentially more radical but also
more aggressive? Or should we favor conservative techniques like shaving or discoid
resection, which aim to reduce complications while preserving fertility?
The objective of this study was precisely to
assess the
impact of these two surgical strategies on
postoperative fertility
in patients desiring pregnancy, and to determine whether a less invasive
approach could offer comparable—or even better—benefit-risk outcomes.
The results show that pregnancy rates were
similar in both groups,
exceeding 60%, whether pregnancies were spontaneous or achieved through
assisted reproduction. However, conservative surgery led to significantly
fewer severe complications, indicating a better tolerance profile without
compromising clinical outcomes.
Nonetheless, the study has
several
methodological limitations, highlighting the need for
prospective, controlled
trials to refine surgical strategies based on
individual patient priorities:
symptom relief, functional preservation, and parenthood plans.
Ultimately, this study reignites a
fundamental
debate in endometriosis surgery:
Is doing more always better for effectiveness? Or, in some cases, can doing less actually preserve more—especially when it
comes to fertility?
