Can hernia recur after surgery?
dr. Teoh Tiong Ann replied 2 years ago

Hernia can recur after surgery. The reported recurrence rates range from 1% to 20%. As in all surgical procedures, it would be best to consult an experienced surgeon to perform the surgery. The common type of surgery performed nowadays is Laparoscopic Hernia Repair. This is the key-hole method where a few small incisions are made and a hernia mesh is used to repair the hernia. It is also important that the patient has adequate rest and restrain from carrying heavy weights and strenuous physical exercise for a few weeks after surgery to allow the wound to heal and for the repair to be strong. This can also help to reduce the recurrence.

Doctor, my mother’s stools are watery, and she always defecates after eating. I gave her medicines for diarrhoea but her condition persists. Please give me your advice on what happened to her. She is 68 years old.
dr. Teoh Tiong Ann replied 2 years ago

At 68 years old with recent bowel symptoms, it is important to get an accurate diagnosis and ensure that there are no serious conditions causing her symptoms. I would suggest that you bring her to consult a gastroenterologist or colorectal surgeon for assessment. She may require tests like blood tests, stool tests and a colonoscopy.

Doctor, my left stomach hurts so much and my bowel movement is hard and hot. Why is this so? I am a 32 year old male.
dr. Teoh Tiong Ann replied 2 years ago

At 32 years old, it is unlike that you have a serious disease. Chronic constipation is a relatively common condition. It usually arises out of poor habits. It is important to drink adequate water, have a healthy diet with adequate fibre, exercise regularly. It is also important not to hold your stool for too long as the stools will harden and it makes it more difficult to defecate after that. It is also best not to consume laxative medication. If your symptoms are recent, it would be better to see a gastroenterologist or colorectal surgeon to ensure that there are no other serious causes.

I often find it hard to defecate, I feel a stomach ache, but when I go to the toilet I will be squatting for long durations of time but the feces does not emerge. I feel bloated because of this issue.  I can always hold back when I want to defecate, up to 12 hours. Do you know why and is it dangerous?

I am a 39 year old male. I have suffered from haemorrhoids for a long time but in the past year, I had trouble defecating. There was a lump in my anus during defecation and I inserted it back in afterwards. The feces that came out were flat, sometimes dark brown. Could this possibly mean I have cancer?
dr. Teoh Tiong Ann replied 2 years ago

The symptoms that you describe suggest a prolapse of the hemorrhoids. This is when the hemorrhoids ‘pop out’ or ‘prolapse of the anus. Hemorrhoids do not affect the size of stools as hemorrhoids are usually soft and do not obstruct the anal canal. It would be best to consult a colorectal surgeon to examine your anus properly to find any causes of the change in calibre of the stools. You may require a colonoscopy to ensure that there are no other serious causes.

I had digestive problems, diarrhoea, blood in my feces, and am experiencing bloating and sudden weight loss for about 1 month. I’ve consulted with the doctor, and consumed some medicines but I’m not getting better. Does this condition usually require surgery?
dr. Teoh Tiong Ann replied 2 years ago

From the combination of symptoms as well as the one month history without any improvement, I strongly suggest that you consult a specialist like a gastroenterologist or colorectal surgeon for proper assessment and more tests. You may require blood tests, stool tests and a colonoscopy. Many conditions do not require surgery and can be treated with medication.

My anus itches after hemorrhoids surgery. Is this normal?

Sadam Farizzi answered 2 years ago

Good afternoon, Doctor. My anal canal is red and swollen, and there is a lump inside it. What is the cause? It hurts and it is uncomfortable.

Rishi answered 2 years ago
Hello Sir, I was feeling a small lump ( mostly in the evening ) in my left side of scrotum . So i went to GP and Urologist , Both have done the clinical examination and said i do not have Hernia for sure . just To clear my worried mind , He asked me to to do ultrasound if i think so. When i did ultrasound , As per ultrasound i am dignosed with bilateral inguinal hernia with left side is large and right one very small. Should i rely on ultrasound or clinical examination in this case ? How soon i need to repair it . It casuse mild discomfort when i sit for long time and my appetite is low.
dr. Teoh Tiong Ann replied 2 years ago

In this instance, it would be best to rely on a clinical examination by the doctor. Ultrasound to look for hernia will also pick up ‘clinically insignificant’ hernia. There is no need to rush to operate on clinically insignificant hernia. However, sometimes, the hernia are not seen during the physical examination by the doctor as they are small. You should look for some of the signs so that you can report this to your doctor.

Some signs that would be very suggestive of a hernia include:
1. Lump is more obvious on standing up
2. Lump disappears or gets smaller on lying down
3. Ability to feel the lump and push the lump back in
4. Usually, when the lump is pushed back in, you can feel a ‘gurgle’

Hernia and the symptoms of discomfort are usually more pronounced on standing up, not sitting. Hernia also do not affect the appetite.
