About

NIMS-trained Surgical Gastroenterologist with GI oncology focus

Dr. J.K. Kumar is a Visiting Consultant Surgical Gastroenterologist and GI Oncology Surgeon at Vivekananda Hospital, Begumpet. He holds an MBBS, DNB General Surgery, and DrNB Surgical Gastroenterology from Nizam's Institute of Medical Sciences (NIMS), Hyderabad. With over 10 years of specialist surgical practice, his clinical focus is advanced gastrointestinal surgery, particularly cancer surgery for stomach, colon, rectum and oesophagus.

The DrNB Surgical Gastroenterology from NIMS is a major credential. NIMS is Telangana state's premier tertiary teaching hospital, and the surgical gastroenterology training programme there exposes trainees to high-volume complex cases: advanced gastric cancers, rectal cancers needing low anterior resection, oesophageal cancer surgery, intestinal obstruction, inflammatory bowel disease surgery, and complex re-operative abdominal cases. Few private hospital surgeons in Hyderabad have this depth of training.

At Vivekananda Hospital, his evening OPD (6-8 PM Mon-Sat) is used for consultations, pre-operative evaluation, post-operative follow-up, and patients seeking second opinions on GI cancer diagnoses. He is the primary Surgical Gastroenterologist at the hospital, with Dr. Nava Kishore also available as Visiting Surgical Gastroenterologist focused on hepato-pancreatico-biliary (HPB) cases.

His sub-specialty focus is GI Oncology - cancers of the gastrointestinal tract. GI cancers are among the most common cancers in India: colorectal cancer, stomach cancer, and oesophageal cancer together account for a significant portion of cancer diagnoses. Surgical management of these cancers requires both technical precision and oncological judgment about lymph node dissection, margins, and adjuvant treatment coordination. His practice combines laparoscopic approach where appropriate with open surgery for complex cases.

GI cancer surgery is about more than removing the tumour. The right lymph node dissection, the right margins and the right adjuvant coordination decide long-term outcomes. NIMS training taught me to focus on the oncology, not just the surgery.

Patient Questions

Frequently asked questions

How do I book an appointment with Dr. Kumar?
Call +91 72079 04418 or WhatsApp the same number. OPD hours at Vivekananda Hospital are Monday to Saturday, 6:00 PM to 8:00 PM (evening only). Evening hours suit working professionals who need post-office consultations. Advance booking is recommended.
What is the difference between a Gastroenterologist and a Surgical Gastroenterologist?
A Gastroenterologist (Medical) is a physician trained in GI disease management through medication and endoscopy. A Surgical Gastroenterologist is a surgeon with specialist training in GI surgery, including advanced cancer surgery of stomach, colon, rectum, pancreas, liver and bile ducts. Dr. Kumar is a Surgical Gastroenterologist with DrNB from NIMS, Hyderabad.
Why is DrNB from NIMS a strong credential?
NIMS is Telangana's premier state tertiary teaching hospital. The DrNB Surgical Gastroenterology programme there involves 3 years of high-volume, high-complexity case exposure under experienced faculty. Trainees manage advanced cancers, complex re-operative cases and teaching responsibilities. Few private hospital surgeons in Hyderabad have this level of structured training.
How is he different from the other surgeons at the hospital?
Dr. Kumar is the primary Surgical Gastroenterologist with GI oncology focus - cancers of stomach, colon, rectum and oesophagus. Dr. Nava Kishore is the Visiting Surgical Gastroenterologist with HPB focus (liver, pancreas, bile duct). Dr. Deeraj Jaliwar handles laser proctology and general laparoscopy. Dr. Abhilash N is the Visiting General Laparoscopic Surgeon. Your condition determines which surgeon is most appropriate.
I have been diagnosed with colon cancer. What happens next?
Colon cancer management involves staging (CT scan, sometimes PET-CT), pre-operative optimisation, and surgery to remove the affected segment with adequate lymph nodes. Dr. Kumar discusses surgical approach (laparoscopic vs open), post-operative recovery, and coordinates with medical oncology for adjuvant chemotherapy if needed. Modern colon cancer surgery has good outcomes when done with proper oncological principles.
Are colonoscopy and endoscopy done at Vivekananda?
Yes. Vivekananda Hospital has the endoscopy setup for diagnostic and therapeutic upper GI endoscopy (gastroscopy) and colonoscopy. Dr. Kumar performs diagnostic procedures, polypectomy, biopsy, and GI bleeding control. These are usually day-care procedures with patient discharged the same day.
Does he perform robotic surgery?
Robotic surgery requires specific Da Vinci robotic equipment available only at select tertiary centres in Hyderabad. Dr. Kumar performs laparoscopic GI surgery at Vivekananda Hospital, which offers most of the same patient benefits (small incisions, less pain, faster recovery). For cases that specifically require robotic assistance, he coordinates referral to appropriate tertiary centres.
When should I consider surgery for Crohn's disease or ulcerative colitis?
Surgery is considered when medical therapy fails, when complications develop (strictures, fistulas, abscess, bleeding, perforation, high-grade dysplasia), or when quality of life is severely affected by poorly controlled disease. Modern IBD surgery often uses laparoscopic approach and aims to preserve bowel length. Surgery timing and technique are discussed with the patient's medical gastroenterologist.
I have a family history of colorectal cancer. Should I be screened?
Yes. Family history significantly increases colorectal cancer risk. Screening colonoscopy is recommended starting at age 45 for average risk, or earlier for those with family history (typically 10 years before the age of diagnosis in the affected relative). Very high-risk syndromes (Lynch, FAP) need even earlier and more frequent screening. Dr. Kumar evaluates risk and recommends appropriate screening interval.
Are GI cancer surgeries covered by insurance?
Yes. Vivekananda Hospital is empanelled with CGHS, ESI, Aarogyasri, Arogyabhadratha and 25+ private insurers. GI cancer surgeries, colon and rectum surgeries, laparoscopic procedures, and endoscopic interventions are typically covered as medically necessary. Bring policy documents before admission for cashless eligibility confirmation.
