Gastroenterology Surgery

Assoc. Prof. Dr. Fuat Atalay, who leads the Gastroenterological Surgery team at Güven Hospital, has been conducting research in this field for over 30 years and has worked at Port Royal Hospital in Australia for a period, specifically focusing on laparoscopic techniques. Dr. Atalay performs approximately 250-300 minimally invasive surgeries annually, with a track record including over 300 esophagus and pancreas cancer surgeries and a series of more than 800 stomach cancer cases. All diseases within the Gastroenterology Surgery Department are evaluated by a specialized team, and a treatment plan is developed, taking into consideration the patient's expectations and quality of life.

These include:

• Esophageal diseases (cancer, reflux, hiatal hernia, achalasia)

• Stomach and duodenum diseases (cancer, morbid obesity, metabolic surgery, tumors), small and large intestine diseases (ulcerative colitis, Crohn's disease, cancers)

• Anus and anal canal diseases (fissure, fistula, hemorrhoids, incontinence, prolapse, abscess)

• Liver diseases (cancer, hydatid cyst, portal hypertension)

• Pancreas diseases (cancer, pancreatic pseudocysts, and cysts)

• Gallbladder and bile duct diseases (gallstones, bile duct stones, cholecystitis, cancers).

Diseases treated in the Gastroenterology Surgery Department:

• Benign and malignant tumors of the esophagus Tumors

In the esophagus can be benign or malignant, and in most cases, they need to be removed through surgical operations due to their potential danger. This procedure is performed by specialized physicians in our gastroenterology surgery department.

• Benign and malignant tumors of the stomach Tumors

Occurring in the stomach mucosa can be benign or malignant. After investigating their type, size, and tendency to become cancerous, stomach tumors should be surgically removed by specialists in our gastroenterology surgery department.

• Surgical procedures for diaphragmatic hernia and reflux disease

Diaphragmatic hernias and gastroesophageal reflux diseases, which can be observed in all age groups, can be completely eliminated or their effects minimized through surgical operations performed by specialists in our gastroenterology surgery department.

• Surgical diseases of the small intestine

Surgical procedures are involved in the treatment of obstructions, adhesions, ulcer formation, tumors, fistulas, diverticula, and hernias that occur in the small intestine. The surgery for these diseases is performed by physicians in the gastroenterology surgery department.

• Laparoscopic and open surgeries for colon and rectum cancers

Benign tumors detected in the large intestine and rectum are usually removed through surgical operations, considering their sizes and following the physician's recommendation. Malignant tumors, regardless of their size, are removed through surgical interventions. After the procedure, an examination is conducted to determine whether there is any spread to different tissues, and additional treatments are applied if necessary.

Surgical procedures for inflammatory bowel diseases (Crohn's disease and Ulcerative colitis)

Inflammatory bowel diseases such as Crohn's disease and ulcerative colitis are managed by evaluating various factors together, including how the treatment will be directed, the location of the disease, the patient's symptoms, and the patient's age. In some cases, it may be necessary to remove a portion of the small intestine and the entire large intestine. Laparoscopic and robotic methods are applied in surgical procedures for this purpose.

• Treatment of hemorrhoids, anal fissure, anal fistula, and pilonidal sinus

Pilonidal sinus, also known as pilonidal cyst, anal fistula developing between the last part of the large intestine and the skin, anal fissure described as a crack in the anus, and hemorrhoid disease, commonly known as piles, are diseases within the scope of gastroenterology surgery that can be treated with surgical operations.

• Surgery for pancreatic cysts and tumors

Various cysts and tumors can occur in the pancreas. In some cases, if these cysts do not pose any danger to patients, they can be monitored. However, the majority of these cysts and tumors are lesions that need to be surgically removed.

• Treatment of acute and chronic pancreatitis and complications

In the treatment of acute and chronic pancreatitis and their complications, surgical operations may be required in addition to endoscopic methods.

• Surgical treatment of all types of liver tumors

Liver tumors are common and, in some cases, may not cause any problems for the patient. However, in certain situations, they may tend to become cancerous, leading to serious issues. Surgical removal is performed when necessary, considering the size and malignancy of these tumors.

• Surgical procedures for hepatic cystic diseases

Parasitic (infection-related) cysts and non-parasitic (structural or cancer-related) cysts in the liver are removed through surgical operations if they pose a danger or if deemed necessary by the physician.

 • Surgical treatment of gallstones and tumors in the gallbladder and ducts

Stones that form in the gallbladder can cause inflammation in the gallbladder and ducts, leading to infections and blockages in the ducts. Additionally, tumors can develop in the gallbladder or ducts. Surgical operations for diseases caused by tumors and stones in the gallbladder and ducts are performed by specialists in the Gastroenterological Surgery Department.

• Surgical treatment of hematological, cystic, and tumoral diseases of the spleen

Hematological diseases, cystic, and tumoral problems are among the diseases that can occur in the spleen. In cases where it is deemed necessary, surgical procedures are performed in our Gastroenterological Surgery Department. The most common of these procedures is splenectomy, the removal of the spleen.

• Laparoscopic surgery for abdominal wall and surgical site hernias

Gastroenterological surgery practices are utilized in the treatment of adhesions and similar issues in the abdominal wall, as well as hernias at the surgical site. Laparoscopic techniques can be employed for these procedures if the patient's health condition allows and the disease permits.

Endoscopy Applications

• Diagnostic gastroscopy and colonoscopy

Gastroscopy and colonoscopy procedures are required for the diagnosis and treatment of certain diseases. Gastroscopy is preferred for the examination of stomach diseases, while colonoscopy is chosen for the examination of colorectal diseases.

• Percutaneous endoscopic gastrostomy (PEG)

To ensure healthy and adequate nutrition for patients who cannot eat or should not eat through their mouths, a procedure called percutaneous endoscopic gastrostomy (PEG) is performed in the gastroenterological surgery department, where a feeding tube directly reaching the stomach is inserted.

• Endoscopic stent placement

In cases where there are strictures in the gastrointestinal system, the stricture can be eliminated by placing a stent in the relevant area using endoscopic methods. This procedure can be performed in the gastroenterological surgery department under suitable conditions.

Advanced laparoscopic applications

Laparoscopic obesity surgeries

Surgical operations for the rapid treatment of obesity include sleeve gastrectomy, gastric bypass, and diabetes surgery. These surgical interventions are performed laparoscopically to minimize potential health risks for the patient.

• Laparoscopic gastroesophageal reflux, achalasia, and hiatal hernia surgeries

Gastroenterological surgery utilizes advanced laparoscopic procedures to treat conditions such as reflux, which results from the breakdown of the structure between the esophagus and stomach, achalasia, causing food to get stuck in the esophagus, and hernias in the diaphragm muscle.

• Laparoscopic colectomy, laparoscopic anterior and lower anterior resections

In cases where complications arise or treatment is unresponsive in inflammatory bowel diseases (such as Crohn's disease or Ulcerative colitis), surgical removal of the intestines may be necessary. In these situations, laparoscopic small intestine resection, total proctocolectomy, and other surgeries allow for a much faster recovery compared to open surgical procedures.

• Laparoscopic splenectomy

The removal of the spleen due to hematological diseases or injuries is referred to as splenectomy. Laparoscopic splenectomies, performed using advanced laparoscopic techniques, involve much smaller incisions compared to open surgeries, resulting in a shorter hospital stay.

Laparoscopic appendectomy

Appendicitis, a common and acute condition, requires urgent surgery. The appendectomy procedure, which was previously performed as an open surgery, is now carried out using laparoscopy, a closed method. Patients undergoing the operation can return to their daily lives within 1-2 days.

• Laparoscopic adrenalectomy

The adrenal glands are endocrine glands located above the kidneys. Both benign and malignant tumors in the adrenal glands, as well as tumors that secrete hormones, can be removed using a laparoscopic adrenalectomy, a closed surgical procedure.

• Laparoscopic cholecystectomy

In cases of gallstones and inflammation, obstruction, and jaundice related to the gallbladder, the definitive solution is cholecystectomy surgery. Cholecystectomy, the removal of the gallbladder, can now be rapidly performed using the laparoscopic method with small incisions.
