Sigmoidoscopy in Nepal
High-definition examination of the rectum and sigmoid colon with minimally invasive treatment options for lower digestive tract issues, by skilled GI specialists.
What is Sigmoidoscopy?
Sigmoidoscopy is a minimally invasive procedure that allows doctors to examine the rectum and the lower part of the colon (sigmoid colon) using a flexible tube with a camera. Unlike a full colonoscopy, which inspects the entire colon, it focuses on the lower digestive tract. It helps to detect early signs of colorectal disease, polyps, early tumors, inflammation, ulcers, hemorrhoids, or cancer.
At Clinic Neo, our sigmoidoscopy test follows strict safety protocols and uses the latest equipment, ensuring a comfortable and reliable examination.
सिग्मोइडोस्कोपी भनेको के हो?
सिग्मोइडोस्कोपी एक न्यून आक्रामक (Minimally Invasive) चिकित्सा प्रक्रिया हो, जसमा क्यामेरा जडित लचिलो ट्युबको प्रयोग गरेर मलाशय (Rectum) र ठूलो आन्द्राको तल्लो भाग (सिग्मोइड कोलोन) को जाँच गरिन्छ। सम्पूर्ण ठूलो आन्द्राको जाँच गर्ने कोलोनोस्कोपीभन्दा फरक, सिग्मोइडोस्कोपीले ठूलो आन्द्राको तल्लो भागको मात्र परीक्षण गर्छ।
यस परीक्षणले कोलोरेक्टल रोग, पोलिप्स (Polyps), प्रारम्भिक ट्युमर, सुन्निने समस्या (Inflammation), अल्सर, पाइल्स (बवासीर) तथा क्यान्सर जस्ता समस्याहरूको प्रारम्भिक चरणमै पहिचान गर्न मद्दत गर्छ।
क्लिनिक नियोमा सिग्मोइडोस्कोपी परीक्षण अन्तर्राष्ट्रिय सुरक्षा मापदण्डको पालना गर्दै अत्याधुनिक उपकरणको प्रयोगबाट गरिन्छ, जसले बिरामीलाई सुरक्षित, सहज र भरपर्दो परीक्षण अनुभव प्रदान गर्छ।
Conditions Diagnosed & Monitored with Sigmoidoscopy

Sigmoidoscopy is crucial for early detection, monitoring, and prevention of lower digestive conditions, including:
- Rectal bleeding or blood in stool
- Chronic constipation or diarrhea
- Unexplained abdominal or pelvic pain
- Colorectal polyps
- Early-stage colorectal cancer
- Inflammatory bowel diseases (Ulcerative colitis, Crohn’s disease affecting lower colon)
- Follow-up after abnormal stool tests or imaging

What Our Patients Say
EXCELLENT Based on 55 reviews Posted on Google Sikum LimbuTrustindex verifies that the original source of the review is Google. Nice one❤️Posted on Google dhanbahadur tamangTrustindex verifies that the original source of the review is Google. Nice friendly clinic for treatmentPosted on Google Phurba TamangTrustindex verifies that the original source of the review is Google. One of the best clinic for treatmentPosted on Google Lopasang GurungTrustindex verifies that the original source of the review is Google. I live abroad and was on holiday in Nepal. I had internal hemorrhoids since 2013 but I ignored it and decided not to treat it. When I was on holiday in Nepal last year 2025, I started to experience relentless discharge and pain while I seat. The pain was so immense that I decided to get surgery. Now the question is where do I go? I asked chat GPT and got Neo clinic as the top choice. I went to the clinic and to my surprise, they do triage (OPD) and surgery on same day. I went there at 4 pm and by 9PM, I was at my house. I was diagnosed with 3rd grade hemmoroids which i was aware of and fistula which was causing me a lot of pain. Thanks to Dr Romi Dahal (surgeon) and his team and the nurse Abishek bhai. They were extremely professional and made me feel very comfortable through out the process. It’s been a month and now I feel like a new and happy man. Thank you Clinic Neo. With that being said, if you experience symptoms of fistula, then I would recommend you immediately go check up because I later on found out that the reason one of my cousin passed away was the infection caused by fistula which she ignored. I know it’s kind of embarrassing which was exactly my initial thought before i got surgery, but trust me, Clinic Neo is the way to go.Posted on Google zygote69Trustindex verifies that the original source of the review is Google.

Frequently Asked Questions
A sigmoidoscopy is used to examine the lower part of the large intestine, mainly the rectum and sigmoid colon. It helps detect problems like polyps, inflammation, ulcers, bleeding, infections, and early colorectal cancer. It is commonly advised for symptoms such as blood in stool, bowel habit changes, or lower abdominal pain.
सिग्मोइडोस्कोपी परीक्षण ठूलो आन्द्राको तल्लो भाग (रेक्टम र सिग्मोइड कोलोन) जाँच गर्न प्रयोग गरिन्छ। यसले पोलीप, सुन्निने, अल्सर, रक्तस्राव, संक्रमण र प्रारम्भिक क्यान्सर पत्ता लगाउन मद्दत गर्छ। दिसामा रगत देखिनु, दिसाको बानीमा परिवर्तन वा तल्लो पेट दुखाइ हुँदा यो परीक्षण गरिन्छ।
The main difference lies in how much of the colon is examined. Sigmoidoscopy examines only the lower part of the colon (rectum and sigmoid colon), while colonoscopy examines the entire large intestine.
सिग्मोइडोस्कोपी र कोलोनोस्कोपीबीचको मुख्य फरक जाँच गरिने आन्द्राको भाग हो। सिग्मोइडोस्कोपीले केवल आन्द्राको तल्लो भाग (रेक्टम र सिग्मोइड कोलोन) जाँच गर्छ भने कोलोनोस्कोपीले सम्पूर्ण ठूलो आन्द्रा जाँच गर्छ।
Yes, some bowel preparation is needed for sigmoidoscopy, but it is much simpler than colonoscopy prep. Usually, a rectal enema or mild laxative is enough to clean the lower bowel.
हो, सिग्मोइडोस्कोपीका लागि आन्द्रा सफा गर्नुपर्छ, तर यो कोलोनोस्कोपीको तुलनामा धेरै सजिलो हुन्छ। प्रायः रेक्टल इनेमा वा हल्का रेचक औषधि प्रयोग गरेर तल्लो आन्द्रा सफा गरिन्छ।
No, sigmoidoscopy is usually less uncomfortable than colonoscopy. Most patients feel only mild pressure or cramping, and sedation is often not required. As the scope travels a shorter distance and the procedure is quicker, discomfort is minimal and well tolerated.
सिग्मोइडोस्कोपी सामान्यतया कोलोनोस्कोपीभन्दा कम असजिलो हुन्छ। अधिकांश बिरामीले हल्का दबाब वा ऐंठन मात्र महसुस गर्छन् र प्रायः निढ्स आवश्यक पर्दैन। नली कम दूरीसम्म मात्र जान्छ र प्रक्रिया छोटो हुने भएकाले दुखाइ न्यून हुन्छ र सजिलै सहन सकिन्छ।
Recovery after sigmoidoscopy is very quick. Most patients can resume normal activities within a few hours. Mild gas or bloating may occur but usually settles quickly.
सिग्मोइडोस्कोपीपछि रिकभरी छिटो हुन्छ। अधिकांश बिरामी केही घण्टाभित्रै सामान्य काममा फर्किन सक्छन्। हल्का ग्यास वा पेट फुल्ने समस्या हुन सक्छ, तर चाँडै निको हुन्छ।
