Gastric Surgery Side Effects And What To Expect After Surgery

Nowadays, gastric surgery is mainly performed to treat stomach tumors. After such procedures, patients may experience a range of short-term and long-term side effects. Understanding these potential complications can help patients prepare and manage their recovery more effectively.

Short-Term Side Effects After Gastric Surgery

The first few days after surgery are critical, and certain complications may arise during this period. One of the most common early complications is postoperative bleeding. This can occur if a blood vessel was not properly sealed during the operation or if sutures become dislodged, leading to internal hemorrhaging.

Another concern is anastomotic leakage. When part of the stomach is removed, the remaining portion must be reconnected to the intestine. If this connection—called an anastomosis—does not heal properly, it can result in a leak. This may happen due to poor surgical technique or the patient's compromised nutritional status, which can impair healing.

Long-Term Side Effects And Complications

Intestinal Obstruction

In the months or years following surgery, some patients may develop bowel obstruction. This can be caused by several factors, including the length or angle of the reconnected intestines, or the formation of adhesions—scar tissue that can cause the intestines to stick together or kink. In severe cases, a second surgery may be necessary to correct the issue.

Changing Trends In Gastric Surgery

It's important to note that aside from gastric cancer, the number of stomach surgeries being performed has decreased significantly over the years. Previously, patients suffering from peptic ulcers or perforations were often treated with partial gastrectomy. However, medical advancements have changed this approach.

Modern medications have drastically reduced the incidence of ulcers, and when they do occur, most can be effectively managed with pharmaceutical treatment and dietary adjustments. As a result, fewer patients are requiring surgical intervention for conditions like gastric ulcers or perforations.
