What is a fixed sigmoid colon?

Are you tired of the same old boring conversation topics? Aching to spice things up and impress your friends with bizarre medical facts? Look no further than the world of gastrointestinal anomalies! In this article, we will explore the hilariously named fixed sigmoid colon – what it is, how it happens, and why you should care.

The Basics

Before we dive headfirst into fecal matter (pun intended), let’s review some digestive system vocabulary. The sigmoid colon is a part of your large intestine located just before your rectum. Its primary function is to store fecal matter until elimination. However, in rare cases, the sigmoid colon can become “fixed” or immobile due to various factors such as abdominal surgeries or congenital abnormalities.

How It Happens

So how exactly does one end up with a fixed sigmoid colon? Well my dear reader, there are several ways:

Blame it on Birth

One possible cause of a fixed sigmoid colon is congenital anomalies – meaning that someone was born with their intestine improperly formed. This could include conditions such as:

  • Hirschsprung’s disease
  • Chronic intestinal pseudo-obstruction

These conditions may contribute to an individual developing decreased motility in their intestines leading to various complications including constipation.

Did Someone Say Surgery?

Sometimes abdominal surgeries result in adhesions or scarring which tether parts of the bowel together creating restrictions within its lumen; If these scars occur in areas that restrict normal peristaltic movement eventually segments may undergo functional adaptation making them less mobile and less able from contracting propulsively especially when compared anatomically synonymous sections so they cannot carry out regular digestion activities effectively thus necessitating interventions[footnoteRef:1]. Since abdominal surgeries involve opening up parts of our gut for necessary operation resection taking out whole section/volume inadvertently occurs thereby contributing/reinforcing the concept of permanence and immobility.

Lifestyles of the Unhealthy

Another potential cause is a sedentary lifestyle or bad diet; this can lead to overall reduced peristalsis, which affects the entire GI tract including your sigmoid colon.


Now that we know how a fixed sigmoid colon occurs let’s talk about how it presents in people who have it:

  • Constipation
  • Abdominal bloating and pain while passing stool/pooping
  • Inability to pass gas effectively (fart way too much)
  • Feeling full even when you have not eaten much food

These symptoms may vary depending on individual predispositions but generally if they have perhaps undergone abdominal surgeries before then consider visiting physician pronto.


If you’ve read this far, congratulations! Now let’s get into some more juicy details like how do doctors diagnose a fixed sigmoid colon?
Common diagnosis procedures include:

  1. Imaging scans such as X-rays, CT Scans, Barium enemas permits visualisation however addition contrast medium might be employed for evaluation[footnoteRef:2]. Although this technique isn’t invasive, many describe an uncomfortable sensation therefore brave ready patients must note or rather endure that aspect.
  2. Physiologic testing to assess continence efficiency.[^3]
    Whereby urodynamics uretero-cystography urethrography defecography are employed [^4] ; these methods are invasive hence interventionists with necessary expertise should conduct them whilst administering suitable analgesics(pain killers) since those areas quite sensitive.

While there is no definitive diagnosis process/tests gastroenterologist/gynecologist will assist in alleviating whatever issue(s) is/are being experienced by affected persons after thorough assessments culminating in determining professionalism required [^5].


A “fixed” condition often implies something nonreversible so does anything any medical approach ever work? There’s no clear procedure for treating a fixed sigmoid colon but that does not mean all hope is lost yet. What follows are some ways to alleviated symptoms:

  1. Laxatives – these help the individual poop thereby reducing congestion or blockages in colonic lumen because constipation only worsens the situation exacerbating pain and bloating..
  2. Balloon-assisted sigmoidoscopy where EPs(GI endoscopists ) expand their selected balloons via catheters until appropriate tension reaches so as to create spaces between walls thus allowing smoother passage of stools.
  3. Surgery (in IVS cases) – this might be necessary if obstruction gets too intense.


Avoiding factors contributing to immobility such as bad diets, leading sedentary lifestyles, going about cleaning up post surgery after precise recommendations from licensed professionals/physicians can have healthy effects [^6]. It really all comes down towards living life healthily and avoid aggravations!


At last, you’re now an expert on a rare phenomenon fixed sigmoid colon; despite its odd name it isn’t a laughing matter for those affected by it[footnoteRef:7]. The goal of these discussions therefore entails encouragement regarding early detection, proper diagnosis along with suitable intervention which should alleviate problematic scenarios persons faced . If things persist please seek out professional medical assistance[^8] .
