Colorectal Surgery in Dhaka — Dr. Muhammad Nazrul Islam: Best Colorectal Surgeon in Bangladesh for Piles, Fistula, Fissure, Cancer & All Anorectal Conditions
Colorectal Surgery / কোলোরেক্টাল সার্জারি / পায়ু ও মলাশয়ের অস্ত্রোপচার
কোলোরেক্টাল সার্জারি (colorectal surgery) হলো কোলন, রেক্টাম এবং পায়ু (anus) এর রোগ নির্ণয় ও চিকিৎসার শল্য বিশেষত্ব। এতে জরুরি অবস্থা (তীব্র ডাইভার্টিকুলাইটিস, বোয়েল অবস্ট্রাকশন) এবং পরিকল্পিত অপারেশন (পাইলস, ফিস্টুলা, পলিপ, কোলোরেক্টাল ক্যান্সার) অন্তর্ভুক্ত।
Colorectal surgery is the surgical specialty covering diagnosis and treatment of diseases of the colon, rectum and anus. It encompasses both emergency procedures (acute diverticulitis, bowel obstruction, perforation) and elective procedures (piles, fistula, polyp removal, colorectal cancer surgery).
Dr. Muhammad Nazrul Islam is a colorectal surgeon with 20+ years of experience treating the full spectrum of colorectal conditions — from common benign conditions (piles, fissure, fistula) to complex colorectal cancer requiring multidisciplinary planning and sphincter-preserving surgery. He is one of the few surgeons in Bangladesh with dedicated postgraduate training in colorectal surgery (MS, Colorectal Surgery) combined with fellowship qualifications (FCPS Surgery, FACS).
Dr. Muhammad Nazrul Islam manages colorectal emergencies and elective procedures in Dhaka — including laparoscopic colectomy, low anterior resection (LAR) for rectal cancer, MIPH stapled haemorrhoidopexy for piles, VAAFT fistula repair, and management of inflammatory bowel disease (IBD). This page covers everything a Bangladeshi patient needs to know about colorectal conditions and their treatment.
সংক্ষেপে / Quick Summary
- Colorectal surgery — surgical specialty covering colon, rectum and anus diseases
- Most common colorectal conditions in Bangladesh: piles (50-60% prevalence), anal fissure, fistula, rectal bleeding, constipation, anal itching, rectal prolapse, pilonidal sinus, colorectal cancer, and inflammatory bowel disease (IBD: ulcerative colitis, Crohn’s disease)
- Piles: Most common colorectal condition — 50-60% of Bangladeshis experience piles at some point — usually managed medically but 10-20% require surgical treatment with MIPH or haemorrhoidectomy
- Rectal bleeding: Most alarming symptom — has 8 causes from piles to colorectal cancer — requires proper assessment, never assume it is only piles
- Anal fissure: Painful tear in the anal canal — common in Bangladesh — usually heals with conservative treatment but chronic fissures require surgical sphincterotomy
- Fistula: Abnormal connection between rectum and skin — usually results from abscess — requires surgical fistulotomy or VAAFT for complex cases
- Constipation: Chronic constipation affects large proportion of Bangladeshis — assessment identifies treatable causes — medical and surgical options available
- Anal itching: Persistent itching — 9 causes including piles, fistula, pinworm, fungal infection — usually highly treatable once cause identified
- Rectal prolapse: Rectum protrudes outside anus — more common in women and elderly — treated surgically with rectopexy (Wells operation)
- Proctitis & rectal pain: Inflammation of rectum — multiple causes including ulcerative proctitis, infectious proctitis, radiation proctitis
- Pilonidal sinus: Sinus tract in natal cleft — very common in young men — Dr. Nazrul performs Karydakis and Limberg flap procedures with <5% recurrence
- Colorectal cancer: 3rd most common cancer globally — most Bangladeshi patients present at advanced stage — curative treatment is colectomy or LAR with D3 lymphadenectomy + adjuvant chemotherapy
- Ulcerative colitis: Chronic autoimmune IBD of colon — frequently misdiagnosed in Bangladesh as dysentery — diagnosed by colonoscopy + biopsy — treated with mesalazine, immunosuppressants, biologics, or surgery
- Crohn’s disease: Chronic autoimmune IBD affecting any part of gut — causes perianal fistula in 30% of patients — must be differentiated from abdominal TB before starting immunosuppressants
- Minimally invasive techniques: MIPH, VAAFT, laparoscopic colectomy, endoscopic polypectomy now standard — faster recovery, less pain, shorter hospital stay
- Dr. Nazrul Islam: 20+ years experience, 50,000+ procedures, FCPS + MS (Colorectal Surgery) + FACS — performs all colorectal procedures including complex cancer surgery with sphincter preservation

সকল কোলোরেক্টাল রোগ / All Colorectal Conditions Treated by Dr. Nazrul Islam
Dr. Nazrul treats the complete range of colorectal and anorectal conditions. Select your condition below for the full patient guide — symptoms, causes, diagnosis and treatment options in Bangladesh:
পাইলস / গেজ রোগ — Piles (Haemorrhoids)
The most common colorectal condition in Bangladesh — 50-60% of Bangladeshis experience piles at some point. Internal and external piles, Grades I–IV. Symptoms: bleeding, itching, pain, prolapse. Treated with MIPH stapled haemorrhoidopexy (daycare procedure), rubber band ligation or conventional haemorrhoidectomy depending on grade.
পায়খানায় রক্ত — Rectal Bleeding / Bleeding from Anus
Blood in stool or on toilet paper — the most alarming symptom that sends patients to a colorectal surgeon. Has 8 causes from piles to colorectal cancer. Symptoms: bright red blood on paper or in stool, dark/tarry stools. Requires proper assessment — never assume it is only piles without examination and colonoscopy if indicated.
পায়ুপথে ঘা — Anal Fissure
A painful tear in the lining of the anus — causes sharp pain during and after passing stool, often with bright red blood. Very common, very treatable. Most fissures heal with conservative treatment (stool softeners, topical anesthetics, sitz baths). Chronic fissures (>6 weeks) may need lateral internal sphincterotomy (LIS) surgery.
ভগন্দর — Fistula & Anorectal Abscess
An abnormal tunnel between the anal canal and perianal skin — causes persistent discharge, pain and recurrent abscess. Usually results from perirectal abscess. Requires surgery. Simple fistulas treated with fistulotomy. Complex fistulas (high level, recurrent, Crohn’s-related) need specialist technique: VAAFT, LIFT, advancement flap.
কোষ্ঠকাঠিন্য — Constipation
Chronic constipation affects a large proportion of Bangladeshis — often untreated or self-medicated with laxatives. Symptoms: infrequent bowel movements, hard stools, straining, incomplete evacuation. Assessment identifies treatable causes: slow transit constipation, outlet obstruction, pelvic floor dysfunction. Medical and surgical options available.
মলদ্বারে চুলকানি — Anal Itching (Pruritus Ani)
Persistent itching around the anus — 9 causes including piles, fistula, pinworm, fungal infection, dermatitis, poor hygiene, irritant contact dermatitis, lichen sclerosus, and idiopathic. Accurate diagnosis determines treatment. Usually highly treatable once cause is identified.
মলদ্বার বের হয়ে আসা — Rectal Prolapse
The rectum protrudes outside the anus — partial or complete. More common in women and the elderly. Often misidentified as piles. Symptoms: bulge during bowel movements, mucus discharge, incomplete evacuation, fecal incontinence. Treated surgically with rectopexy (Wells operation) — Dr. Nazrul’s recurrence rates far below the national average.
মলদ্বারে ব্যথা — Proctitis & Rectal Pain
Inflammation of the rectum causing pain, urgency and discharge. Multiple causes: ulcerative proctitis (IBD), infectious proctitis (STI, TB), radiation proctitis (post-cancer treatment), solitary rectal ulcer syndrome. Also covers proctalgia fugax — sudden severe rectal pain with no structural cause. Treatment depends on underlying cause.
নিতম্বের ঘা — Pilonidal Sinus
A sinus tract in the natal cleft (between the buttocks) — causes recurrent abscess and discharge. Very common in young men. Symptoms: pain, swelling, drainage of pus/blood. Simple excision has 15–40% recurrence; Dr. Nazrul performs Karydakis and Limberg flap procedures with <5% recurrence rate.
কোলন ক্যান্সার — Colon & Rectal Cancer
Colorectal cancer — the most serious colorectal condition — 3rd most common cancer globally. Most Bangladeshi patients present at advanced stage. Symptoms: rectal bleeding, change in bowel habit, weight loss, abdominal pain. Highly treatable if caught early. Surgery: laparoscopic colectomy, LAR (sphincter-preserving), APR. Colonoscopy screening available.
রক্ত আমাশয় (IBD) — Ulcerative Colitis
Chronic autoimmune inflammatory bowel disease (IBD) of the colon — NOT infectious dysentery. Frequently misdiagnosed in Bangladesh as রক্ত আমাশয় and treated with antibiotics for years. Symptoms: chronic diarrhea, blood in stool, abdominal pain, weight loss. Diagnosed by colonoscopy + biopsy. Treated with mesalazine, immunosuppressants, biologics, or surgery if refractory.
পেটের প্রদাহ (IBD) — Crohn’s Disease
Chronic autoimmune IBD affecting any part of the gut — mouth to anus. Critical Bangladesh distinction: must be differentiated from abdominal tuberculosis before starting immunosuppressants. Causes perianal fistula in 30% of patients. Symptoms: chronic diarrhea, abdominal pain, weight loss, perianal disease. Surgery is NOT curative — disease recurs. Medical management first-line.
সচরাচর জিজ্ঞাসা / Frequently Asked Questions
কোলোরেক্টাল সার্জারি কি? / What is colorectal surgery?
Colorectal surgery is the surgical specialty covering diagnosis and treatment of diseases of the colon, rectum and anus. It includes both emergency procedures (acute diverticulitis, bowel obstruction, perforation) and elective procedures (piles, fistula, polyp removal, colorectal cancer surgery). Dr. Nazrul is one of the few surgeons in Bangladesh with dedicated postgraduate training (MS) in colorectal surgery.
পাইলস কেন হয়? / Why do piles develop?
Piles develop due to increased pressure in the rectal veins. Risk factors: chronic constipation, straining during bowel movements, prolonged sitting, pregnancy, obesity, heavy lifting, chronic diarrhea, aging. Internal piles are above the dentate line and usually painless but bleed. External piles are below the dentate line and cause pain and itching.
পায়খানায় রক্ত সবসময় পাইলসের কারণে হয় কি? / Is rectal bleeding always due to piles?
No — rectal bleeding has 8 causes: piles, anal fissure, fistula, polyps, colorectal cancer, diverticulosis, inflammatory bowel disease (IBD), and infectious colitis. Never assume rectal bleeding is only piles without proper examination and colonoscopy if indicated. Some causes (colorectal cancer) are serious and require urgent assessment.
MIPH কি? / What is MIPH?
MIPH (Procedure for Prolapse and Haemorrhoids) is stapled haemorrhoidopexy — a minimally invasive procedure for Grade III–IV piles. Single-session daycare procedure. No external wound. Rapid recovery (1-2 weeks). Lower pain compared to conventional haemorrhoidectomy. Dr. Nazrul performs MIPH for suitable candidates.
পায়ুর ফিস্টুলা কেন হয়? / Why do anal fistulas develop?
Anal fistulas develop when a perirectal abscess ruptures or is inadequately drained — creating an abnormal connection between the rectum and skin. Risk factors: inflammatory bowel disease (Crohn’s disease), trauma, infection, immunosuppression. Fistulas do not heal on their own — surgical treatment is required.
VAAFT কি? / What is VAAFT?
VAAFT (Video-Assisted Anal Fistula Treatment) is a minimally invasive technique for complex anal fistulas — uses an endoscope to visualize and treat the fistula tract from inside the rectum. Advantages: preserves anal sphincter, lower recurrence rate, faster recovery. Particularly useful for high-level, recurrent, or Crohn’s-related fistulas.
কোলোনোস্কপি কি? / What is colonoscopy?
Colonoscopy is a minimally invasive procedure using a flexible tube with a camera (colonoscope) to visualize the entire colon and rectum. Used for: screening for colorectal cancer and polyps, diagnosis of GI bleeding, IBD evaluation, polyp removal (polypectomy). Recommended screening: age 45-50+ every 10 years if normal. Therapeutic colonoscopy can remove polyps or perform biopsies.
রক্ত আমাশয় এবং আলসারেটিভ কোলাইটিস কি একই? / Is dysentery the same as ulcerative colitis?
No — they are completely different. Dysentery is infectious (bacterial or parasitic) and acute. Ulcerative colitis (UC) is chronic autoimmune IBD — NOT infectious. UC is frequently misdiagnosed in Bangladesh as dysentery and treated with antibiotics for years without improvement. Proper diagnosis requires colonoscopy + biopsy. UC is treated with mesalazine, immunosuppressants, biologics — not antibiotics.
ক্রোন্স ডিজিজ এবং আলসারেটিভ কোলাইটিসের মধ্যে পার্থক্য কি? / What is the difference between Crohn’s disease and ulcerative colitis?
Crohn’s disease: Can affect any part of gut (mouth to anus), transmural inflammation, causes fistulas and strictures. Ulcerative colitis: Affects only colon/rectum, mucosal inflammation only, causes bleeding and diarrhea. Both are chronic autoimmune IBD requiring long-term medical management. Surgery is NOT curative for either — disease can recur.
সার্জারির পর কতদিন কাজ করতে পারব? / How long before I can return to work after colorectal surgery?
Return to work depends on the type of surgery: MIPH (piles): 1-2 weeks desk work, 4-6 weeks heavy work. Fistula surgery: 2-3 weeks desk work, 6-8 weeks heavy work. Anal fissure surgery: 1-2 weeks desk work, 4-6 weeks heavy work. Rectal prolapse surgery: 4-6 weeks desk work, 8-12 weeks heavy work. Colectomy: 6-8 weeks desk work, 3-4 months heavy work.
