Transverse colon cancer is a type of colon cancer. Generally speaking, in terms of diet, one should not eat spicy, stimulating, or hard-to-digest foods, such as overly spicy food, hot pot, smoked, grilled, or pickled foods. It is best to avoid these, as well as alcohol and tobacco. Because transverse colon cancer can lead to intestinal blockage as the tumor grows, consuming spicy, stimulating, or indigestible foods, or overeating and causing indigestion, can lead to intestinal obstruction. This is a relatively high risk, and typically, once transverse colon cancer is diagnosed, consideration should begin for primarily curative surgery.

Colon cancer surgical methods

The surgical approach for colon cancer should be tailored based on the specific circumstances of the patient, involving a rational, comprehensive treatment strategy. The surgical principle is that early-stage cancers should undergo curative resection, while more advanced cancers should be treated with radical surgery or extended radical surgery. Once the treatment plan is determined, the choice of surgical methods should be made comprehensively based on the patient's specific conditions. For example, in the surgery of rectal cancer in the middle and lower segments, it should be considered whether to preserve the anus or perform abdominoperineal resection based on the tumor's biological characteristics, patient's age, overall health, and any concurrent diseases. It is not that there is one fixed type of surgery; the approach should be specifically tailored based on the detailed analysis of the issues at hand.

How to defecate after transverse colon cancer surgery

If transverse colon cancer is treated with curative resection surgery and no stoma creation, the anus is preserved, and defecation occurs through the original anus. If a colostomy is performed after surgery for transverse colon cancer, defecation occurs through an artificial anus, typically located in the lower left abdomen. There can be opportunities to reverse the stoma later if necessary. Even with a stoma, patients can gradually adapt. The main focus is always on completely removing the tumor. Generally, postoperative adjuvant chemotherapy is also used to control the condition.

Is minimally invasive surgery suitable for transverse colon cancer?

Transverse colon cancer can also be considered for minimally invasive surgical treatment. The main procedure involves a complete resection of the transverse colon, and sometimes, it may require the resection of part of other organs. For instance, if the cancer has invaded the splenic region of the colon, a splenectomy may be necessary. If there is invasion into the liver area, partial liver resection may be needed. In cases where minimally invasive surgery is not suitable or inconvenient, it is also possible to switch to open surgery. The goal is to completely remove the tumor. Whether minimally invasive or traditional surgery is used, it is just a method of operation. Additionally, postoperative adjunct chemotherapy and other comprehensive treatments are necessary.

Colorectal Cancer CT Manifestations and Differential Diagnosis

Early-stage colon cancer is difficult to clearly detect on a CT scan. In the moderate to late stages, colon cancer has more typical manifestations on CT, mainly characterized by thickening of the colon wall, irregular narrowing of the intestinal lumen, and stiffness of the intestinal wall. After enhancement, significant enhancement can be observed. The pericolonic fat space may appear blurred, and in the late stages, small lymph nodes can be seen, and even distant metastasis, most commonly to the liver, can be detected. It is necessary to differentiate colon cancer from colonic inflammation. Inflammatory lesions are usually more widespread and have typical clinical features such as fever and abdominal pain. It is also necessary to differentiate from lymphoma, as lymphomas also cause narrowing of the intestinal lumen but the narrowing is not eccentric and the intestinal wall remains soft, generally not leading to obstruction, whereas in late-stage colon cancer, colonic obstruction can be observed.

Differentiation between Colon Polyps and Colon Cancer

The most distinct diagnostic criteria between colon polyps and colon cancer are that colon polyps are benign lesions, whereas colon cancer is a malignant tumor of the intestines. Colon polyps are generally small in size or present as multiple polyps, with localized mucosal elevation. They may appear the size of mung beans or be pedunculated, and may be accompanied by mild abdominal pain, generally without blood in the stool. In contrast, during the onset of colon cancer, there is usually abdominal pain accompanied by bloody stools. In the later or advanced stages of colon cancer, after the tumor ruptures, it may also lead to severe gastrointestinal bleeding, as well as overall bodily wasting and anemia. The prognosis for colon polyps is relatively good; regular follow-up checks are sufficient. However, for colon cancer, if detected early, surgical removal can be an option. The survival rate in the middle and late stages is lower than in the early stage, and treatment may require a combination of radiotherapy and chemotherapy.
