# What is Small Bowel Resection? Overview, Benefits and Expected Results

Small bowel resection is a surgical procedure involving the removal of⁣ a small portion of‌ the small ‌intestine, or small bowel. Small bowel resection is commonly⁢ used to treat conditions ⁤such as Crohn’s disease, cancer, ⁤intussusception, volvulus, and strictures. ⁤It is also ⁤sometimes used to treat gastrointestinal bleeding.

## What⁣ is Small Bowel ‌Resection?

Small bowel resection is a‌ procedure where a portion of⁢ the small ‍intestine is surgically removed. This procedure ‌is⁤ typically done to treat medical conditions ⁤such as cancer, Crohn’s disease, ‌diverticulitis, intussusception,⁣ volvulus, strictures and gastrointestinal ⁣bleeding. The length of the section of small bowel removed vary depending on the condition being treated and can range ‌from a few centimeters to several feet.

During small‌ bowel resection, the surgeon will use equipment⁣ to ‍carefully cut away the affected portion of ⁢the small intestine. The ends of the healthy intestine are then⁢ stitched⁣ together. This allows for ‌the normal flow of ‍food and nutrients through⁣ the remaining⁢ intestine and ‌prevents hazardous leakage.​

Sometimes, a portion of the​ affected⁢ intestine​ will be ‍removed and ‌examined in⁣ a laboratory to confirm the diagnosis. This procedure‌ is known‍ as an intraoperative biopsy.

## Benefits of Small Bowel Resection

The primary benefit of small bowel⁢ resection is improvement‌ in, or complete resolution of, the symptoms ‌associated with the‍ condition that is being treated. ‌Conditions ​such as Crohn’s disease can cause severe abdominal pain, abdominal cramping, ⁤diarrhea, and even life-threatening malnutrition. Removing the affected portion of ⁣the⁢ small intestine⁣ can thus provide tremendous relief⁢ from these symptoms.

In some cases, small bowel resection can also reduce ‍the‍ risk of long-term complications ⁢associated with certain medical conditions. For instance, in cases where small bowel resections are used to treat ⁢cancer,⁤ it can help to slow the progression of ⁣the disease or even ⁢reduce the ⁣chance​ of it spreading to other areas in the body.

##⁢ Expected‌ Results‌ After Small Bowel Resection ⁣

Most ⁣people who undergo small bowel resection can expect to‌ recover completely ⁤within 6-12 weeks. However, the recovery period​ may be‍ longer for some people. ‌It is important to consult with your health care provider to​ get an accurate estimation of ‍recovery‍ time.

The recovery process typically includes ⁤both physical and emotional elements. It is important to ⁢take time to rest and⁤ to follow the ‍instructions from your health care provider regarding medications,​ lifestyle changes, and other ⁢recommended treatments.

It is also important to note that it⁢ is normal ⁣to⁣ experience⁤ some pain and discomfort during the recovery process. Your pain ​should gradually subside over ‍time.⁣

The expected outcome of small bowel resection is usually improved, or complete‍ resolution, of the symptom being⁢ treated. In the⁤ long run, small bowel ⁤resection can reduce​ the risk of long-term complications for some medical conditions.

In summary,‌ small bowel resection is a surgical procedure involving the removal of part or all​ of the small intestine and can be used to ‌treat conditions such as Crohn’s disease, cancer, ⁢intussusception, volvulus, and ​strictures. The benefits of​ small bowel‌ resection include relief‍ of symptoms associated with the condition ‍being treated and in some cases it can reduce the risk of long-term complications. Following small bowel resection, most people can‍ expect to recover within 6-12‌ weeks ⁣and can expect improved or complete resolution of the symptom being ⁢treated.

Definition and Overview

The small bowel or small intestine is the tube that connects the stomach to the colon (large intestine). It is the part of the digestive system responsible for absorbing nutrients from the food a person eats. The organ is made up of three segments, namely:

  • Duodenum – The first and shortest segment that receives partially digested food from the stomach.

  • Jejunum – The middle segment where most nutrients from food are absorbed.

  • Ileum – The last segment that intersects with the large intestine.

Any of these parts can be damaged and if the damage is beyond repair, small bowel resection can be performed. Depending on which part is removed, the procedure is referred to as duodenectomy (removal of all or part of the duodenum), jejunectomy (excision of all or part of the jejunum), or ileectomy (removal of all or part of the ileum).

Who Should Undergo and Expected Results

Small bowel resection is used to treat the following conditions:

  • Cancer of the small intestine – Malignant tumours can form in the small intestine and cause a blockage. In the majority of cases, doctors elect to remove the section where the cancer is found to treat the condition. The surgery is often followed by chemotherapy or radiation therapy to ensure that no cancer cells remain in the small intestine. Small bowel resection is also used if precancerous polyps and noncancerous tumours are found in the organ.

  • Crohn’s diseaseCrohn’s disease is a painful and debilitating inflammatory bowel disease that is associated with a number of life-threatening complications. It is initially treated with lifestyle changes and drug therapy with surgery reserved as the last option. If patients are unable to experience symptoms relief with non-invasive treatments, small bowel resection is performed.

  • Severe ulcers – Ulcers refer to holes in the mucous membrane of the small bowel. They usually occur due to infections or cancer and often cause severe bleeding.

As for the expected results, most patients recover well from surgery while some experience complications including problems with absorbing enough nutrients, which can lead to malnutrition.

How is the Procedure Performed?

Prior to the procedure, the patient undergoes blood, urine, and imaging tests as well as electrocardiogram (EKG). The surgeon will also discuss the details of the surgery, the technique to be used, and possible risks and complications. Preoperative bowel preparations, such as completely cleaning the bowel and taking antibiotics, are standard practice.

Before the actual surgery, a nasogastric tube is inserted through the nose. It prevents vomiting and nausea as well as removes gastric secretions during the procedure. A urinary catheter is also used to keep the bladder empty.

Small bowel resection can be performed either through traditional open surgery or laparoscopically.

In a traditional open surgery, the surgeon makes a long incision in the abdominal wall to access and remove the diseased part of the intestine. The same is the goal of laparoscopic surgery, which uses up to five small incisions where a miniature camera, light, and surgical tools are inserted. The two healthy ends of the resected small intestine are then stapled or sewn together (anastomosis). If this is not possible, the surgeon will create an opening in the belly called a stoma where the end of the resected intestine is attached.

Many surgeons and patients prefer laparoscopic surgery because it is minimally invasive. Patients typically recover faster because their wounds are much smaller and the interruption to their digestive system is minimal.

The procedure, which is often performed under general anaesthesia, can last between one to four hours. Following surgery, patients are transferred to a recovery room until the effects of anaesthesia wear off. They are then moved to a regular hospital room where they typically stay for a week before being discharged.

Possible Risks and Complications

Most people who undergo small bowel resection recover fast and return to their normal activities weeks after the procedure. Some, however, suffer from chronic diarrhea and malnutrition as the small intestine’s ability to absorb enough nutrients from food has been compromised.

Small bowel resection rarely leads to serious risks and complications. However, a small number of patients experience the following:

  • Excessive bleeding

  • Scar tissue formation resulting in the blockage of intestine

  • Infection

  • Hernia at the incision site

The risk of complication is higher in patients who are smokers, malnourished, or suffering from chronic illnesses or have undergone abdominal surgery in the past.

Patients are discharged about a week following a small bowel resection. They are urged to call their doctor if they develop any signs of infection, persistent abdominal pain, rectal bleeding, chest pain, and urinary symptoms.
