Cancer is a large group of diseases that can start in almost any organ or tissue of the body when abnormal cells grow uncontrollably, go beyond their usual boundaries to invade adjoining parts of the body and/or spread to other organs. The latter process is called metastasizing and is a major cause of death from cancer. A neoplasm and malignant tumor are other common names for cancer.

Cancer is the second leading cause of death globally. It is certain that early diagnosis saves life.

Our clinic provides ‘Hybrid’ Cancer Screening according to patient`s age , family history or own risk factors. This non-invasive solutions include Circulating tumor clusters (CTCs) in blood for Colon & Rectum, Breast, Gastric, Pancreas, Gallbladder, Liver cancers, etc. combination with advanced screening tools as Artificial Intelligence Endoscopy, Mammography, Elastography Ultrasound, MRI and multi-slice CT scans.

Overweight and obesity are major risk factors for a number of chronic diseases, including cardiovascular diseases such as heart disease and stroke, which are the leading causes of death worldwide. Being overweight can also lead to diabetes and its associated conditions, including blindness, limb amputations,

and the need for dialysis. Carrying excess weight can lead to musculoskeletal disorders including osteoarthritis. Obesity is also associated with some cancers, including endometrial, breast, ovarian, prostate, liver, gallbladder, kidney and colon. The risk of these non communicable diseases increases even when a person is only slightly overweight and grows more serious as the body mass index (BMI) climbs.

Non-Surgical combination  treatments of endoscopic bariatric procedures combination with medical treatments aim both prevention of population from morbid obesity and treatment of morbid obese patients. Prevention strategies are suitable for overweight adults(BMI 25-30) and Class1 and Class2 obese adults (BMI>30). Treatment is needed for Class3 Morbidly obese patients(BMI>40).

Endocrine Diseases (Thyroid, parathyroid, adrenal, endocrine pancreas) and Cancer Treatment

The endocrine system is a collection of glands and organs that regulate bodily processes using hormones. Endocrine system regulates a range of processes, including metabolism, reproduction, and growth.  Most of cancers in endocrine system and some of function disorders of endocrine system need surgical treatment.

The upper gastrointestinal tract encompasses the mouth, esophagus, stomach and duodenum, the first part of the small intestine. There are many diseases of the upper digestive tract and  they can significantly impact your health. The symptoms can substantially affect your quality-of-life and psychological wellbeing. Symptoms of upper gastrointestinal diseases vary depending upon the condition. Some of the symptoms include difficulty swallowing, nausea, vomiting, heartburn, difficulty in the passage of food, belching, bloating, regurgitation of food and loss of appetite.

Prof.Dr.Bas provides both surgical and non-surgical solutions for upper gastro-intestinal diseases that includes:

• Gastritis, stomach and duodenal ulcers treatments

• Esophageal strictures treatments(Endoscopic balloon dilatation and stenting treatments)
• Stomach cancer surgeries
• Esophageal cancer surgeries,

• Gastrointestinal stromal tumor (GIST) surgeries

There are many common problems affecting the colon and rectum. These conditions include irritable bowel syndrome, constipation, hemorrhoids, anal fissures, abscess, colitis, polyps and colon cancer.

Colon cancer is one of most common cancer worldwide. But it is also one of the most preventable types of cancer – if you undergo regular colon cancer screenings. Having a periodic colonoscopy can identify growths (called polyps) within your large intestine. Because almost all colon cancers begin as a polyp, this type of screening is very effective at removing suspicious tissue before cancer has a chance to develop. It is also particularly important to have regular colonoscopies because colon cancer typically causes no symptoms. When symptoms do appear, it may mean that the cancer has already significantly advanced.

Prof.Dr.Bas provides a Hybrid Cancer Screening Program by Artificial Intelligence Colonoscopy and CTCs in blood sample.

He performs advanced endoscopic therapeutic approaches as:

• Endoscopic Mucosal Resection (EMR)
• Endoscopic Submucosal Dissection (ESD)
• Self-Expandable Metal Stent (SEMS) application for malignant stenosis for bridging to the surgical treatment
• Endoscopic balloon dilation for benign stenosis
• Endoscopic treatment of lower gastrointestinal bleeding
• Endoscopic treatment of lower gastrointestinal perforations

He also provides minimally invasive surgical solutions for  colon and rectum diseases as:

• ‘’Incision-less’’ Transanal Endoscopic Minimally Invasive Surgery (TAMIS)
• Pure Laparoscopic Colon and Rectum Surgery
• Hand-Assisted Laparoscopic Colon and Rectum Surgery (HALS)
• Single Incision Laparoscopic Surgery (SILS) for temporary ileostomy and colostomy

Breast disorders may be noncancerous (benign) or cancerous (malignant). Most are noncancerous and not life threatening. Often, they do not require treatment. In contrast, breast cancer can mean loss of a breast or of life. Thus, for many women, breast cancer is their worst fear.  Among women, breast cancer is the most common cancer and the second most common cause of cancer deaths.

Prof.Dr.Bas treats and follow ups benign breast diseases and provides a hybrid screening program for malign diseases by mammography, US-Elastogram and MRI and CTCs in blood sample.

He also provides surgical solutions for breast cancer as:

• “Oncoplastic” breast conserving surgery (OBCS)
• Breast Conserving Surgery with “Coil Marker” by Neoadjuvant Chemotherapy for Locally Advanced Breast Cancer treatment
• “Guide-wire localized” Breast Conserving Surgery
• Sentinel Lymph Node Biopsy (SLNB) by double tracer: Lymphoscintigraphy and Blue Dye Injection
• Modified Radical Mastectomy (MRM) with immediate or delayed breast reconstruction [accompanied by Plastic Surgeon]

• “Microductectomy” for Central Intraductal Papilloma or Ductal Ectasia

A hernia occurs when an internal organ or other body part protrudes through the wall of muscle or tissue that normally contains it. Most hernias occur within the abdominal cavity, between the chest and the hips.

The most common forms of hernia are inguinal hernia, femoral hernia, umbilical hernia and hiatal hernia.

A neglected hernia can grow larger and more painful — this can lead to complications and possibly emergency surgery. Early repair is more successful, less risky and offers a better recovery and outcome. Hernias usually do not get better on their own, and surgery may be the only way to repair them.

Prof.Dr.Bas provides minimally invasive surgical solutions for hernias as:

• Totally Extra Peritoneal (TEP) inguinal hernia repair
• Extended Totally Extra Peritoneal (e-TEP) abdominal wall hernia repair
• Transabdominal Pre-Peritoneal (TAPP) inguinal hernia repair

• Laparoscopic repair of parastomal hernia
• Laparoscopic repair of diaphragmatic hernia
• Laparoscopic treatment options for recurrent abdominal wall hernias

Benign Perianal Diseases (Hemorrhoids, Anal Fissure, Perianal Fistula, Rectal Prolapsus) Treatment

Anorectal disorders like hemorrhoids, rectal prolapse, anal fissures and peri-anal fistulae are bothersome benign conditions that warrant special attention. They, however, can all be diagnosed by inspection or proctoscopy . Hemorrhoids and anal fissures are generally treated conservatively and surgery is seldom required. Rectal prolapse and peri-anal fistulae are treated surgically.

Prof.Dr.Bas provides both surgical and non-surgical solutions for benign perianal diseases as:

• Non-surgical Laser hemorrhoidoplasty for early-stage Hemorrhoids
• Surgical Closed Hemorrhoidectomy for late-stage Hemorrhoids
• Stapler Hemorrhoidopexy for prolapsed Hemorrhoids
• Non-surgical Botox treatment for early-stage Anal Fissure
• Surgical treatment for late-stage Anal Fissure
• Stapled treatment for Rectal Prolapsus
