GASTRIC SLEEVE

POSSIBLE COMPLICATIONS

Overweight Women

Laparoscopic gastric sleeve gastrectomy (LSG)is gaining popularity for the treatment of morbid obesity. It is a simple, low-cost procedure resulting in significant weight loss within a short period (Dakwar, Assalia, Khamaysi, Kluger, & Mahajna, 2013). This method is very efficient regarding weight reduction; however, it is associated with some early and long-term complications.

Gastric sleeve is becoming a standard stand-alone surgical procedure in providing treatment for morbid obesity. Of the few complications, most shared and essential are staple-line bleedingstrictures (usually located at the middle or distal portion of the residual stomach), and the most severe, dangerous complication being staple-line leaks (Dakwar, Assalia, Khamaysi, Kluger, & Mahajna, 2013).

Most complications become present within the first 30-days of original surgery date, and less than 0.1% of complications are deadly

Bleeding

The risk of postoperative bleeding has been reported to be between 1% and 6% after gastric sleeve. The source of bleeding can be intra- or extraluminal. Intraluminal bleeding from the staple line usually presents with an upper gastrointestinal bleed. Common symptoms include hematemesis or melena stools (Sarkhosh, Birch, Sharma, & Karmali, 2013). Extraluminal bleeding usually presents with a serial drop in serum hemoglobin levels or signs of tachycardia or hypotension. Typical sources for extraluminal bleeding include the gastric staple line, spleen, liver or abdominal wall at the sites of trocar entry (Sarkhosh, Birch, Sharma, & Karmali, 2013).

Gastric Leak along Staple Line

The gastric leak is one of the most severe and dreaded complications of the laparoscopic gastric sleeve. It occurs in up to 5% of patients following LSG (Sarkhosh, Birch, Sharma, & Karmali, 2013). In a retrospective study of patients who underwent LSG, an incidence of 5.6% was found (Frezza, Reddy, Gee, & Wachtel, 2008). It is early when it occurs within the first three days of after surgery and late if it happens after the 8th-day post-surgery.

However, recent research has found that gastric leaks have dramatically been reduced to less than 3%.

Intra-abdominal Abscess

An intra-abdominal abscess is another possible complication of gastric sleeve surgery. It usually presents with symptoms of abdominal pain, fever/chills or nausea and vomiting. If there are clinical suspicions, a computed tomography scan of the abdomen should be done to rule out the presence of intra-abdominal abscess (Sarkhosh, Birch, Sharma, & Karmali, 2013).

Stricture

It could present either acutely after surgery due to tissue edema or more commonly in a delayed fashion. Presenting symptoms include food intolerance, dysphagia or nausea, and vomiting. The most common site of stenosis is at the incisura angular. An upper gastrointestinal study or endoscopy is usually diagnostic (Sarkhosh, Birch, Sharma, & Karmali, 2013).

Malnutrition

Nutrient deficiency is another complication of bariatric surgery. This is majorly due to reduced intake and absorptive capacity. Vitamin B 12, folate, zinc, and vitamin D are the primary nutrients affected.

Gastroesophageal Reflux Disease

Gastroesophageal reflux disease appears in approximately 12% of cases after laparoscopic sleeve gastrectomy. Management includes dietary and lifestyle interventions along with pharmacotherapy, but sometimes revisional surgery is needed (Hernandez & Boza, 2016).

Other non-specific complications are anesthetic complications, injury to the adjacent organs, wound infection, deep vein thrombosis, postoperative adhesive intestinal obstruction, and those related to laparoscopic procedures. These difficulties are not peculiar to LSG and can also occur in other intra-abdominal surgeries.

Laparoscopic sleeve gastrectomy has been a surgical treatment choice for morbid obesity. It is effective in reducing weight in obese patients. Though associated with a small risk of complications, a condition like gastric leak can be life-threatening if not detected and treated early.
