Flexible Sigmoidoscopy at Apollo Hospitals, Lucknow

Flexible sigmoidoscopy is one of the most commonly performed lower gastrointestinal endoscopy procedures for patients with rectal bleeding, altered bowel habit, chronic diarrhoea or a suspected inflammatory bowel condition. At Apollo Hospitals Lucknow, the procedure is carried out within a dedicated endoscopy suite by gastroenterologists and GI surgeons working alongside trained endoscopy nurses and anaesthesia support.

Why Patients Choose Apollo Hospitals, Lucknow

• A gastroenterology and GI surgery team with combined decades of endoscopy experience ? consultants, DM/DNB-qualified gastroenterologists and MCh/MS GI surgeons work together, so a sigmoidoscopy that reveals surgical pathology is reviewed by the right specialist without the patient needing a fresh referral elsewhere.
• Part of the Apollo Hospitals group, established in 1983 ? India's first large-scale corporate hospital network, now operating more than 70 hospitals with over 10,000 beds and a group-wide record of several million patient encounters each year. Apollo's endoscopy protocols, infection-control audits and clinical governance are standardised across the group.
• High-definition video endoscopy systems with narrow-band or equivalent image-enhanced imaging, which improves detection of small or flat polyps and subtle mucosal changes in ulcerative colitis compared with older white-light-only scopes.
• Same-sitting therapeutic capability ? biopsy forceps, cold and hot snare polypectomy, haemostatic clips, argon plasma coagulation for radiation proctitis and injection therapy are available in the same room, so a diagnostic test can become a treatment when appropriate.
• Dedicated endoscope reprocessing using automated endoscope reprocessors and documented high-level disinfection cycles, with traceability of scope, patient and cycle.
• On-site histopathology and laboratory services, so biopsy reporting does not depend on samples being couriered out of the city.
• Anaesthesia and critical care backup for patients who need sedation, and for elderly patients or those with cardiac, respiratory or renal comorbidity.
• Separate pathways for adults, elderly patients and children ? paediatric lower GI endoscopy is planned with paediatric-calibre scopes, weight-based bowel preparation and paediatric anaesthesia input rather than adapting adult protocols.
• Insurance and TPA desk on campus handling cashless pre-authorisation for most major insurers, CGHS/ECHS and state schemes where empanelled.
• Referral catchment across central and eastern Uttar Pradesh, with the hospital used to scheduling same-day pre-procedure workup for patients travelling from outside Lucknow.

Overview

Flexible sigmoidoscopy is a minimally invasive procedure that allows healthcare professionals to examine the lower part of the colon, known as the sigmoid colon, using a flexible tube equipped with a camera. At Apollo Hospitals Lucknow, we pride ourselves on our reputation for excellence in gastrointestinal care, utilising current-generation endoscopic technology and established techniques to work towards the best achievable outcomes for our patients. Our team of skilled gastroenterologists is dedicated to providing personalised care, ensuring that each patient feels comfortable and informed throughout their journey. Apollo Hospitals Lucknow aims to make patient safety and satisfaction the guiding priorities of every endoscopy performed.

In practical terms, the scope is passed through the anus and advanced through the rectum, sigmoid colon and usually up to the descending colon or splenic flexure ? roughly the last 60 centimetres of the large bowel. It does not examine the transverse or right colon; that requires a full colonoscopy.

Why Flexible Sigmoidoscopy is Necessary

Flexible sigmoidoscopy is a crucial diagnostic tool in the early detection and management of various gastrointestinal conditions. This procedure is particularly important for identifying issues such as:

• Colorectal Cancer: Early detection significantly increases the chances of successful treatment.
• Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease and ulcerative colitis can be diagnosed and monitored.
• Polyps: The procedure allows for the identification and removal of polyps before they develop into cancer.
• Rectal Bleeding: It helps determine the cause of unexplained rectal bleeding.

The benefits of flexible sigmoidoscopy extend beyond diagnosis; it can also facilitate therapeutic interventions, such as biopsy or polypectomy, which may improve patient outcomes. At Apollo Hospitals Lucknow, we combine clinical expertise with modern equipment so that patients receive a high standard of care.

Risks of Delay

Delaying a flexible sigmoidoscopy can have serious consequences. Conditions such as colorectal cancer can progress, and early intervention is generally associated with better treatment options. Postponing the procedure may lead to:

• Worsening Symptoms: Conditions like IBD can flare, leading to complications such as severe colitis, strictures or fistulae.
• Increased Risk of Cancer: Adenomatous polyps can transform into cancer over a period of years, making earlier detection important.
• Complicated Treatment: Delayed diagnosis may mean more extensive surgery, chemotherapy or radiotherapy becomes necessary later on.

At Apollo Hospitals Lucknow, we recognise the value of timely assessment. The team works to offer prompt consultations and procedure slots so that patients are not left waiting with unexplained symptoms.

Benefits of Flexible Sigmoidoscopy

• Early Detection: Identifying disease at a treatable stage can meaningfully change outcomes.
• Minimally Invasive: The procedure is less demanding than a full colonoscopy, often requiring no sedation and allowing a quicker return to routine.
• Lighter Preparation: Usually one or two enemas rather than litres of oral bowel-cleansing solution ? an important advantage for elderly patients and those who tolerate purgatives poorly.
• Same-Day Findings: Visual findings are usually explained on the same day, though biopsy results take longer.
• Therapeutic Options: Polyp removal, biopsy and control of bleeding points can be performed in the same sitting.

Preparation and Recovery

Preparation

• Dietary Restrictions: Follow your doctor's instructions regarding dietary changes in the days leading up to the procedure. A low-fibre diet may be recommended.
• Bowel Preparation: You will likely need to take a laxative or use an enema to clear the lower bowel. This step is crucial for obtaining clear images.
• Medication Review: Inform your doctor about all medicines you take, as blood thinners, antiplatelet agents, insulin and iron tablets may need adjustment or temporary interruption.

Recovery

• Post-Procedure Monitoring: You will be observed for a short period to ensure there are no immediate complications.
• Rest: Plan to rest for the remainder of the day. Most patients return to normal activities the following day, and many the same evening if sedation was not used.
• Follow-Up Care: Attend scheduled follow-up appointments to discuss biopsy results and onward management.

At Apollo Hospitals Lucknow, the team provides written instructions tailored to your medical history, medicines and the type of preparation prescribed.

Current Guidance and What Has Changed

Recommendations relevant to Indian practice come from several recognised bodies, and it is worth knowing where they agree and where they diverge.

• Indian Society of Gastroenterology (ISG) and the Indian Society of Gastrointestinal Endoscopy (SGEI) have consistently held that population-wide colorectal cancer screening is not currently justified across India, because incidence is substantially lower than in Western countries. ISG consensus work on ulcerative colitis (published in the Indian Journal of Gastroenterology) instead positions lower GI endoscopy as a symptom-driven and risk-driven investigation, and recommends sigmoidoscopy with mucosal biopsy as the standard first step in suspected or relapsing distal colitis.
• Indian Council of Medical Research (ICMR) Consensus Document for Management of Colorectal Cancer similarly supports opportunistic and high-risk screening ? family history of colorectal cancer, known polyposis or Lynch syndrome, long-standing colitis ? rather than mass screening.
• Guidance that changed recently: the US Preventive Services Task Force lowered the recommended starting age for average-risk colorectal cancer screening from 50 to 45 years in its 2021 statement, and the American Cancer Society had already moved to 45 in 2018. Many Indian gastroenterologists now discuss age 45 with patients who have a family history or other risk factors, but Indian societies have not adopted 45 as a national screening age. Any decision to screen earlier in India is individualised.
• Sigmoidoscopy versus colonoscopy: long-term randomised trial follow-up (NORCCAP, UK Flexible Sigmoidoscopy Screening Trial, PLCO and SCORE) shows that a single flexible sigmoidoscopy reduces distal colorectal cancer incidence and mortality. It does not protect against right-sided cancers. This is why a colonoscopy is generally advised when the concern is proximal disease, iron-deficiency anaemia, positive faecal immunochemical test, or a strong family history.
• Ulcerative colitis surveillance: current international guidance (ECCO, ASGE, AGA) favours high-definition chromoendoscopy-assisted full colonoscopy with targeted biopsies for dysplasia surveillance in long-standing colitis ? sigmoidoscopy is used for assessing disease activity, not for cancer surveillance.

What Most Pages on This Topic Leave Out

Competing Indian pages for this procedure tend to cover the definition, indications and a short FAQ list. What they rarely address, and what patients actually ask about, is included below: how the procedure is timed around a working week, how it compares with the alternatives, what an unsedated procedure genuinely feels like, how insurance treats a day-care endoscopy, the specific waiting-period clauses that trip up Indian policyholders, what to do about Indian toilet posture and floor sleeping after polypectomy, and how patients travelling in from Barabanki, Sitapur, Rae Bareli or Gorakhpur should plan the day.

Timing of the Procedure and the Preparation Phase

Alternatives and Technique Options Compared

Your doctor's choice depends on your symptoms, age, haemoglobin, family history and fitness. If a sigmoidoscopy shows disease extending beyond the reach of the scope, a full colonoscopy is usually advised as the next step.

Procedures Sometimes Performed at the Same Time

• Mucosal biopsy ? routine even when the lining looks normal, in suspected microscopic colitis or chronic diarrhoea.
• Polypectomy ? cold snare for small polyps, hot snare or endoscopic mucosal resection for larger ones.
• Haemostasis ? clips, adrenaline injection or argon plasma coagulation for bleeding points, angiodysplasia or radiation proctitis.
• Band ligation of internal haemorrhoids, where these are found to be the bleeding source.
• Dilatation of a short distal stricture in selected cases.
• Tattooing with sterile ink to mark a lesion so a surgeon can locate it later.
• Upper GI endoscopy in the same session when both upper and lower symptoms need evaluation ? this is a common way to reduce cost and the number of hospital visits.

Phase-by-Phase Recovery

Returning to Work, Exercise and Daily Indian Routines

• Diagnostic sigmoidoscopy without sedation: most people return to office or shop work the same afternoon.
• With sedation: no driving, no two-wheeler, no operating machinery and no signing of legal or financial documents for 24 hours. Arrange an attendant.
• Squatting and Indian-style toilets: comfortable after a plain diagnostic test. After polypectomy, prefer a Western commode or a raised commode seat for about a week, since deep squatting increases intra-abdominal pressure and straining over the healing site.
• Sitting cross-legged and floor sleeping: acceptable after a diagnostic test. After polypectomy, avoid repeatedly getting up from the floor unsupported for the first few days; use a wall or a chair for support, or shift to a bed temporarily.
• Gym, weight training and heavy household work such as lifting water drums, gas cylinders or grain sacks: wait one week after polypectomy or hot biopsy; only 24 hours after a plain examination.
• Yoga: gentle walking and pranayama from the next day. Avoid strong abdominal asanas, kapalbhati and inversions for a week after any therapeutic procedure.
• Long journeys, pilgrimages and flights: reasonable after 24 hours for a diagnostic test; defer for about a week after polypectomy so that any delayed bleeding occurs within reach of the treating hospital.
• Fasting practices such as Navratri, Ekadashi, Karva Chauth or Ramzan: tell your doctor beforehand, especially if you are diabetic, so the bowel preparation and the procedure date can be planned sensibly.

Reducing the Chance of Recurrence and Future Disease

• Attend the repeat endoscopy at the interval advised ? polyp recurrence is common, and surveillance is the main protection.
• Increase dietary fibre through whole grains, seasonal vegetables, dals and fruit, while keeping fluid intake adequate.
• Reduce processed and red meat, deep-fried food and reheated oils.
• Stop tobacco in all forms, including gutkha, khaini, zarda and paan masala, and limit alcohol.
• Maintain a healthy weight and 30 to 45 minutes of daily activity; central obesity is an independent risk factor for colorectal neoplasia.
• Treat constipation properly rather than relying on long-term stimulant laxatives or unregulated churans.
• In ulcerative colitis, take maintenance mesalamine or other prescribed therapy continuously ? stopping when symptoms settle is the most common reason for relapse.
• Inform first-degree relatives if a significant polyp or cancer is found; their screening may need to start earlier.

Children, Older Adults and Other Special Situations

Children and adolescents

Sigmoidoscopy in children is most often done for rectal bleeding from juvenile polyps, suspected ulcerative colitis or solitary rectal ulcer syndrome. Paediatric-calibre scopes, weight-based enema volumes and general anaesthesia or deep sedation are standard, with a paediatric gastroenterologist and paediatric anaesthetist involved. A parent is allowed to accompany the child until anaesthesia begins.

Older adults

Sigmoidoscopy is often preferred over colonoscopy in frail elderly patients because the enema-only preparation avoids the dehydration, electrolyte disturbance and falls associated with full oral purgation. Cardiac, renal and diabetic medicines are reviewed in advance, and sedation is kept minimal or avoided where possible.

Pregnancy

Sigmoidoscopy can be performed during pregnancy when there is a clear indication such as significant bleeding or a suspected colitis flare, ideally in the second trimester, with obstetric input, left lateral positioning and minimal or no sedation.

Other situations

• Diabetes: morning slots are preferred; insulin and sulfonylurea doses are adjusted for the fasting period.
• On blood thinners: the decision to stop, continue or bridge is taken jointly with your cardiologist or neurologist.
• Anal fissure or acute painful piles: the test may be postponed or done under sedation to avoid severe pain.
• Suspected severe acute colitis or perforation: only a limited, unprepared examination is done, if at all, because of the higher perforation risk.

If You Decide Not to Have the Procedure

You have every right to decline, and the team will respect that decision. It is fair to know the trade-offs:

• The cause of rectal bleeding remains unconfirmed. Attributing it to piles without looking is the most common reason rectal cancers are diagnosed late in India.
• Treatable inflammatory conditions may go unrecognised, and symptomatic self-medication can mask progression.
• Polyps that could be removed in ten minutes today may need major surgery if they become malignant.
• Alternative, less complete options exist ? a FIT stool test, CT colonography, or an initial trial of treatment with a firm review date. Discuss these openly rather than simply not returning.
• If you defer, agree on specific red flags that would bring you back immediately: increasing bleeding, weight loss, anaemia, a change in stool calibre or new abdominal pain.

Factors That Influence the Cost

Apollo Hospitals Lucknow does not publish a fixed price for this procedure on its website, because the final amount depends on several clinical variables. Please ask the reception, the endoscopy coordinator or the insurance desk for a written estimate before the date. The factors below explain why two patients may be billed differently.

Insurance, Cashless Treatment and TPA Process in India

• Day-care coverage: most Indian health insurance policies now list endoscopic procedures under day-care treatment, meaning a 24-hour hospitalisation is not required for the claim. Purely diagnostic endoscopy done on an OPD basis, however, is often not covered unless the policy has an OPD or diagnostic rider.
• Initial waiting period: typically 30 days from policy inception for anything other than accidental injury.
• Pre-existing disease waiting period: commonly 2 to 4 years depending on the insurer. If you were diagnosed with ulcerative colitis, piles or polyps before buying the policy and disclosed it, the claim may fall within this exclusion.
• Specific-ailment waiting period: many policies carry a 1 to 2 year wait for conditions such as haemorrhoids, fistula and fissure ? relevant if the sigmoidoscopy is being done for those.
• Accident versus planned cover: accident-related admissions are usually payable from day one, while a planned diagnostic endoscopy must clear all applicable waiting periods.
• Cashless process: submit your e-card and photo ID to the insurance desk at least 48 to 72 hours before a planned procedure. The hospital sends a pre-authorisation request to the TPA or insurer, who responds with an approval, a query or a partial approval. Non-medical consumables, registration charges and any amount above the sanctioned limit are settled by you at discharge.
• Reimbursement route: if pre-authorisation is not obtained, pay and claim later with the original bills, discharge or day-care summary, endoscopy report, histopathology report and prescriptions. Most insurers require submission within 15 to 30 days.
• Government and scheme patients: coverage under Ayushman Bharat PM-JAY, state health schemes, CGHS and ECHS depends on current empanelment and package availability. Confirm this with the insurance desk before travelling.
• Do not accept verbal assurances about approval; ask for the written pre-authorisation letter and keep a copy.

Planning the Visit and What to Bring

• All previous endoscopy, colonoscopy, biopsy, ultrasound and CT reports, including films.
• A complete list of medicines with strengths, or the strips themselves.
• Photo identity proof, insurance e-card or TPA card, and any scheme card.
• A responsible adult attendant, mandatory if sedation is planned.
• Loose, comfortable clothing; a spare set of undergarments and a change of clothes.
• Adult diaper or sanitary pads if you have urgency or incontinence ? the nursing staff can also arrange these.
• Water and a light snack for after the procedure, and diabetic patients should carry their glucose monitor and something sweet.
• Leave jewellery and valuables at home; remove nail polish if sedation is planned.
• Note down your questions in advance ? most patients forget them once the report is handed over.

Warning Signs That Need Urgent Review

Contact the hospital or attend the emergency department without waiting for your follow-up appointment if you develop:

• Heavy or repeated fresh bleeding, or passing clots per rectum.
• Severe or steadily worsening abdominal pain rather than settling gas cramps.
• A hard, rigid or markedly distended abdomen.
• Fever with chills in the days after the procedure.
• Persistent vomiting or inability to pass stool or wind.
• Dizziness, fainting, breathlessness, cold clammy skin or a racing pulse.
• Chest pain or palpitations.

Perforation and significant bleeding are uncommon after flexible sigmoidoscopy, but both are treatable when reported early.

For Patients Travelling from Nearby Districts

Apollo Hospitals Lucknow receives patients from Barabanki, Sitapur, Unnao, Rae Bareli, Hardoi, Kanpur, Lakhimpur Kheri, Faizabad and Ayodhya, Sultanpur, Bahraich, Gonda, Basti, Pratapgarh, Jaunpur, Gorakhpur, Varanasi, Prayagraj and parts of Bihar and Nepal's Terai belt. A few practical points:

• Ask the endoscopy coordinator to combine consultation, pre-procedure tests and the procedure so that one or two trips are enough.
• Enemas are usually given at the hospital before the procedure, so you do not have to attempt bowel preparation during a long road or rail journey.
• If sedation is planned, do not travel back on the same day by two-wheeler or as the driver. Plan an overnight stay near the hospital, or bring a driver.
• After polypectomy, staying in Lucknow for 24 hours is sensible so that any early bleeding can be managed at the same centre.
• Biopsy reports can often be shared electronically and discussed by teleconsultation, avoiding a second long journey. Confirm this option at the time of the procedure.
• Carry originals of all outside reports; scans and reports done elsewhere are usually accepted if the films are available.
