Doctors in Mumbai have extracted a gigantic 11-kg tumour from the abdomen of a 55-year-old woman after a marathon nine-hour surgery.A team of medicos headed by oncologist Dr Tanveer A. Majeed, urologist Dr Santosh Palkar and Dr Shilpa Deshmukh performed the complicated surgery at the Zen Multispeciality Hospital in Chembur.The patient Sujata Sinha (name changed) is a housewife who noticed her abdomen growing daily accompanied by breathing difficulties.At the height of lockdown in June, she consulted a local doctor who confirmed the presence of a tumour with ultrasound and CT scan.However, owing to the lockdown she did not take any further steps or medicines, even as the tumour continued to grow rapidly, making her look obese.Finally, she was referred to the ZMH and Dr Majeed checked her condition on September 8 to find she was weighing around 80 kgs, and suffered from diabetes and hypertension.Further tests revealed the huge abdominal tumour encroaching the right half of the abdomen, pushing the right kidney to the left side, duodenum, liver, small intestine and colon to the left side, besides her major blood vessels supplying to the heart.After further clinical diagnosis, the patient was advised surgery by Dr Majeed as it indicated a rare cancer of connective tissues that resemble fat cells under a microscope."After opening the abdomen, we found a huge tumour which had displaced all the other body organs to the left side. It weighed 11 kgs and had dimensions of 55 cm x 40 cm x 35 cm, and the patient lost around one litre of blood during the nine-hour operation," said Dr Majeed.The patient is recuperating well at the hospital now, has started an oral liquid diet, can breathe normally, and will be required for a follow-up after three months."We delayed treatment due to the pandemic lockdown. But I am fortunate to be operated at ZMH where the doctors saved my life. I feel much lighter now, can eat and breathe properly and resume normal life," said the patient gratefully.Prior to this, a team of doctors at the Global Hospital, Parel, had extracted a massive 12-kg tumour from a woman's abdomen in December 2014.
