The large intestine is a part of the digestive tract and it comprises several parts, which have different structures and functions. Hemicolectomy is a surgical procedure performed in order to remove approximately half of the colon and to unite the ileum with the transverse colon. It is usually used to treat diseases of the terminal ileum, cecum or ascendant colon (usually tumors).
While performing a right hemicolectomy, the surgeon removes a part of the small intestine (the terminal ileum), the entire right colon and the afferent lymphatic ganglions that supply the excised portion with blood. After that, he/she unites the rest of the small intestine with the part of the colon that is left (transverse colon). When the tumor affects other organs that cannot be removed, the disease is too advanced and the health state of the patient makes it impossible to perform a broad surgery. Therefore, the tumor is not removed anymore.
There are several complications that a patient might encounter when undergoing a right hemicolectomy, both specific and nonspecific. The diarrhea syndrome appears in 22% of the cases and can have various causes:
- The lack of water and electrolytes absorption because the colon is missing
- Accelerated intestinal transit and retrograde bacterial colonization because the Bauhin valve is missing
- The absence of the terminal ileum, the part of the intestine where the bile salts, which have a role of laxatives, are absorbed
- The terminal ileum is contaminated with colonic bacterial flora, negatively influencing the absorption of bile salts and acids, water and electrolytes
Left hemicolectomy is the surgical intervention that consists in the removal of the left half of the transverse colon, splenic angle, descendant colon and the sigmoid. The digestive continuity is rebuilt through transverso-rectal anastomosis.
General anesthesia is the most used as it allows detailed exploration of the abdomen, perfect muscle relaxation, hemodynamic stability and increased surgical comfort. Tracheal intubation and controlled ventilation are required when the patient is anesthetized completely.
