GASTRO INTESTINAL MALIGNANCIES

GASTROINTESTINAL CANCER 

  • Cancer of the Esophagus

  • Stomach Cancer

  • Anal Cancer

  • Colon Cancer

  • Rectal Cancer

  • Small Intestine Tumors

  • Appendix Tumors

  • Gastrointestinal Stromal Tumor (GIST)

  • Liver Cancer

  • Neuroendocrine Tumors

  • Pancreatic Cancer

  • Bile Duct Cancer

  • Gallbladder Cancer


Surgical Treatment for Cancer of the Esophagus:

  • Surgery is the most common treatment for cancer of the esophagus. The goal of surgery is to completely remove the cancer and all surrounding lymph nodes. Surgery is most effective with early disease, but can be used in conjunction with chemotherapy and radiation for advanced cancer

  • Surgery also provides relief of symptoms such as obstruction and dysphagia (difficulty swallowing)


SURGICAL PROCEDURES:

  • Three hole esophagectomy

  • Ivor-Lewis esophagectomy

  • Transhiatal esophagectomy

  • Thoracoabdominal esophagectomy

  • Minimally Invasive esophagectomy 

 

Stomach Cancer Surgery

 Surgery is a common treatment for stomach cancer, especially when it’s in its early stages. Depending on your situation, we may incorporate minimally invasive surgical techniques when performing gastrectomy to help lessen the risk for complications, shorten your recovery time, and minimize pain.

TYPES OF SURGERY :

  • Partial gastrectomy: It involves removing part of your stomach and the nearby lymph nodes (lymphadenectomy) to determine if they contain cancer cells. Depending on the tumor’s location, your surgeon may also remove parts of other tissues and organs.

  • Total gastrectomy : Your surgeon removes your entire stomach and may also remove parts of other organs and tissues near the tumor. To enable you to continue eating and swallowing normally the surgeon then connects your esophagus to your small intestine.


Lymphadenectomy (lymph node dissection) : 

  • As the cancer might have spread to nearby lymph nodes, your doctor will usually remove some lymph nodes from around your stomach. This reduces the risk of leaving any cancer behind.

  • Laparoscopic Gastrectomy: With his approach, your surgeon inserts a laparoscope (a thin, lighted tube with a video camera at its tip) into your abdomen through a tiny incision in the skin.



COLO RECTAL CANCER SURGERY:

  • Surgery is considered the most common treatment for early stage or resectable (removable) colorectal cancers.

  • Doctors will evaluate which type of surgery is best for a patient, depending on the extent of the tumor, where it is located. 

  • Historically, open surgery for colorectal cancer has been the conventional method for removing tumors. Recent advancements in technology, however, have enabled more laparoscopic  approaches. These are considered minimally invasive surgeries that let doctors make smaller incisions and can decrease recovery time.

 

  • Four common types are right hemicolectomy, sigmoid colectomy, left hemicolectomy, and lower anterior resection (LAR).


Right hemicolectomy:

  • The surgeon removes the ascending colon and a portion of the transverse colon and then connects the transverse colon to the end of the small intestine. Most patients gain bowel function within 3 days after surgery. 

Sigmoid colectomy

  • The surgeon removes the diseased portion of the sigmoid colon and then connects the descending colon to the rectum.

Left hemicolectomy

  • The surgeon removes a portion of the transverse colon, the descending colon, and the sigmoid colon and then connects the transverse colon to the rectum. 

Lower anterior resection (LAR)

  • The surgeon removes the diseased portion of the rectum and then reconnects it to the descending colon. With this type of surgery patients are at higher risk of a leak from the site of reattachment of the health ends of the rectum (anastomotic leak) and fecal incontinence.
