Closed Loop Obstruction. Closed loop obstruction is a specific type of obstruction in which two points along the course of a bowel are obstructed at a single location thus forming a closed loop. Usually this is due to adhesions, a twist of the mesentery or internal herniation. In the large bowel it is known as a volvulus Intestinal obstruction is a blockage that keeps food or liquid from passing through your small intestine or large intestine (colon). Causes of intestinal obstruction may include fibrous bands of tissue (adhesions) in the abdomen that form after surgery; hernias; colon cancer; certain medications; or strictures from an inflamed intestine caused by certain conditions, such as Crohn's disease or. Complications may include narrowing of the bowel (strictures) or abnormal tunnel-like openings (fistulas). Malignant (cancerous) tumors: Cancer accounts for a small percentage of all small bowel obstructions However, closed loop obstructions are characterized by their complete nature and high morbidity and risk of death in case of delayed surgery. In the colon, ischemic complications only occur on volvulus. The most important factor in the prognosis is the time before care

Closed-loop and strangulating intestinal obstruction: CT

These include anastomotic leaks, obstructions, bleeding, ulcers, strictures, and other complications. The timing of such complications varies between patients, but in general, early complications include a leak, bleeding, and postoperative edema. These tend to be more common in the first two weeks after RYG Intestinal volvulus, the prototypical closed-loop obstruction, causes torsion of arterial inflow and venous drainage, and is a surgical emergency

Appendiceal tie syndrome: A very rare complication of a

Introduction . Gallstone ileus (GSI) of the colon is an extremely rare entity with potentially serious complications including perforation. Case Presentation . An 88-year-old man presented to the emergency department with abdominal pain and distension. Clinical exam revealed signs of peritonism. Computed tomography (CT) revealed GSI of the transverse colon with a closed-loop large bowel. The median time interval for visceral complication was reported to be seventeen months (varying from four weeks to thirteen years).9 Medical literature mentions one case of a migrated IUCD which, after 31 years of insertion, had become embedded in the omentum, and each of the two arms of the coil had entered into the lumen of mid ileum, giving rise to a closed loop obstruction.9 Another case. The presence of a single loop of dilated bowel in a patient with acute severe abdominal pain is concerning for a closed-loop obstruction. However, plain X-rays are diagnostic in only 46% to 80% of.

  2. If the obstruction is severe enough, the distended afferent loop may not be able to sufficiently discharge its contents, and a clinical picture of closed loop obstruction manifested as an acute abdomen will result. If this condition is not recognized in its early stages, the afferent loop may actually perforate and result in peritonitis
  3. In closed loop obstruction the lumen of the bowel is occluded at two points thus preventing prograde and retrograde movement of bowel contents. In open-ended obstruction a one-point obstruction interferes with the prograde propulsion of bowel contents. Bowel obstruction may be partial or complete, simple or complicated

Complications after Roux-en-Y gastric bypass include anastomotic leaks and strictures, marginal ulcers, jejunal ischemia, small bowel obstruction, internal hernias, intussusception, and recurrent weight gain Closed Loop Obstruction. If there is a second obstruction proximally (such as in a volvulus or in large bowel obstruction with a competent ileocaecal valve) this is termed a closed-loop obstruction. This is a surgical emergency as the bowel will continue to distend, stretching the bowel wall until it becomes ischaemic or perforates

Surgery is indicated for complicated bowel obstruction, closed-loop bowel obstruction, or if there is no clinical improvement following NOM for simple bowel obstruction. The underlying cause of bowel obstruction should be sought for and managed appropriately. Definition. Bowel obstruction: the interruption of normal passage through the bowe Surgical exploration is indicated in all patients with complete intestinal obstruction, patients with closed-loop obstruction, patients who developed complications of ischemia and perforation and patients with incarcerated hernias. Surgeons apply careful examination of the bowel loops to exclude early ischemia or gangrene

In addition to the standard risks of surgery and anesthesia, possible complications following bowel obstruction surgery include: 3  Edema (accumulation of fluid and inflammation This is known as a closed loop obstruction because there exists an isolated (closed) loop of bowel. Acute volvulus often requires immediate surgical intervention to untwist the affected segment of bowel and possibly resect any unsalvageable portion. Volvulus occurs most frequently in middle-aged and elderly men Closed-loop large-bowel obstruction. Strategies to manage a closed-loop large-bowel obstruction include bowel resection, with or without the formation of a colostomy and colonic stenting. Stenting is associated with complications including migration, further obstruction and perforation, and may require further definitive management In closed loop obstruction, the small bowel is obstructed at two points along its course, thus forming a closed loop. These patients have a high risk of bowel ischemia due to venous infarction, which will result in perforation, septic shock and other complications with a high mortality rate

In a patient with a hostile abdomen and multiple previous laparotomies, surgical management of a closed-loop large-bowel obstruction risks significant morbidity and mortality for the patient, necessitating other strategies for management Hernias can lead to clinically significant complications, such as a closed loop bowel obstruction with or without strangulation and have been reported to be the most common cause of small bowel obstruction (SBO) after laparoscopic RYGB [28,29]. The type of internal hernia is determined most often by the configuration of the Roux limb with three. Edwards, MS, et al. We present the case of a male evaluated in the emergency department for a closed-loop small bowel obstruction due to an adhesive band that likely formed after blunt abdominal trauma over two decades earlier. We review the epidemiology, pathophysiology, and treatment options for similar cases of adhesive SBO

This is usually self limited and rarely causes severe complication.

A closed loop obstruction or internal hernia may be present and requires urg ent surgery due to the risk of bowel wall ischaemia that can result in perforation A rare case of postsurgical small bowel obstruction where a closed intestinal circuit was accidentally created due to incorrect anastomosis of the bowel loops, with the Roux loop anastomosed on itself (Roux-en-O loop) and only the biliopancreatic loop anastomosed on the ileum 3 Suspected Small-Bowel Obstruction pain medication, and sometimes antibiotics. However, imaging and laboratory findings that suggest a higher grade SBO with a complication, such as ischemia, closed-loop obstruction, volvulus, or complete obstruction, may prompt more urgent surgical treatment Closed loop obstructions, other small bowel obstructions not caused by adhesions, or those adhesive small bowel obstruction that fail to resolve at 24 h, require urgent laparotomy. Untreated, or inadequately treated, small bowel obstruction in any setting may lead to bowel ischaemia, portal pyemia and death [ 5 , 6 ]

  2. CT identifies time-sensitive complications of bowel obstruction, including ischemia and perforation. Bowel obstructions can be complicated by time-sensitive catastrophes, such as perforation or intestinal ischemia resulting from a closed loop obstruction. Identification of these complications with CT guides patients toward rapid surgical.

  4. Mucocele can also occur, as it did in this case presentation, as a result of a closed loop obstruction of defunctionalized colon secondary to a stoma complication. In 1974, Nicosia and Abcarian described a patient who developed a colonic mucocele after perineal trauma . The patient had undergone end colostomy with mucus fistula 30 years prior.
  5. A serious and life-threatening complication of bowel obstruction is strangulation. Strangulation is more commonly seen in closed-loop obstructions. If the strangulated bowel is not treated promptly, it eventually becomes ischemic, and tissue infarction occurs. Tissue infarction progresses to bowel necrosis, perforation, and sepsis/septic shock

We report the first case in the peer-reviewed literature of superior mesenteric artery (SMA) syndrome after laparoscopic gastric banding further complicated by proximal obstruction and gastric distension of sufficient magnitude to compromise the venous return and result in necrosis of the mucosa. The closed loop obstruction was relieved by endoscopic decompression and by nasojejunal feeding The same pathophysiology might occur in this situation if the biliary limb becomes obstructed. A closed loop obstruction with potential life-threatening complications could occur if not treated timely. In this situation, one must decompress this closed loop, and typically, surgery is undertaken Bowel obstruction surgery is an interventional procedure that involves both: Removal of any material that's blocking the intestines (such as feces, cancer, a polyp, an infectious abscess, or a twist in the bowel) Repair of regions of the intestine that may have been damaged due to the obstruction Closed loop obstruction due to adhesive band. A Axial contrast-enhanced MDCT image demonstrates two abrupt adjacent transition zones in the right lower quadrant (arrows). B There is dilation and wall thickening of the small bowel loops both proximal to and within the closed loop (asterisks). The patient underwent surgery to release the adhesion.

The closed loop of small bowel was initially dark and congested, but immediately demonstrated healthy reperfusion after it was reduced. Because it was viable, no small bowel resection was performed. We used two Kelly clamps and 2-0 silk sutures to ligate and divide the sigmoid colon epiploica defect (Fig. 6 ) What Is Bowel Obstruction? Bowel (intestinal) obstruction is a partial or complete mechanical blockage of the bowel. Typical symptoms are cramping abdominal pain, nausea, rumbling bowel sounds and cessation of gas.You can suspect bowel obstruction, if you have intestinal hernia, abdominal cancer, diverticulosis, other chronic bowel disease, history of abdominal surgery, or you have ingested a. Complications include: Complete obstruction, closed-loop obstruction, bowel ischemia, necrosis, and perforation. Surgery. Open abdominal surgery is commonly performed in small bowel obstruction. Laparoscopic adhesiolysis is another viable option that has the advantages of: Lower morbidity; Less recovery time; Less complications Simple obstruction occurs at one point. Closed-loop obstruction occurs at two points, which results in rapid increase in intraluminal pressure. Venous and arterial compromise may occur rapidly as well in the proximal and distal bowel segments. Functional: Disruption of normal peristalsis with no true mechanical obstruction An intestinal obstruction means blockage of the small or large intestine and the blockage might be partial or total, thus it prevents the passage of fluids as • Closed - loop obstruction.

Final Diagnosis Loop type of Cecal Volvulus caused by Meckel's diverticulum with an Omphalo-Mesenteric Band, resulting in acute intestinal obstruction and ischemic changes involving cecum, ascendin Acute appendicitis is known to cause intestinal obstruction. The presentation is commonly due to functional obstruction, but on very rare occasions it presents as mechanical obstruction, especially closed loop. We report a case of a 59-year-old Egyptian man who presented with symptoms suggestive of intestinal obstruction. On examination, he was afebrile with distended tender abdomen with no. Complications include: complete obstruction, closed-loop obstruction, bowel ischemia, necrosis, and perforation. Historical Perspective Bowel obstruction has been described as far back as 1550 b.c. in ancient Egypt, however, the earliest record of the first successful treatment of small bowel obstruction was in 350 b.c. by Praxagorus

  1. The differential diagnosis can be made with the following conditions: large bowel obstruction of other etiologies, caecal volvulus and colonic pseudo-obstruction. Sigmoid Volvulus Pictures Sigmoid Volvulus Picture 1 : In the left side image, you can see the unattached loop of bowel getting twisted resulting in the obstruction of bowel lumen.
  2. 3. Small bowel obstruction from internal hernias In Figures 4 and 5, the way how a loop of small bowel can herniate through both the mesenteric defect at the jejunojejunostomy and the Petersen's space are shown. As we can presume, the major risk for an internal hernia is to leave the spaces open
  3. ation with computed tomography (CT) were retrospectively.
  4. Finally, adhesive bands are common complications of laparoscopic surgical approaches, and can present with imaging findings mimicking internal hernias. 8 As adhesive bands may be associated with similar serious complications to internal hernias (i.e., closed-loop obstruction or bowel ischemia), misdiagnosis as an internal hernia is of uncertain.

  6. By the time dyspnea occurs, airway obstruction is moderately or severely advanced. Looked at differently, spirometry can detect airway obstruction in COPD 5 to 10 years before dyspnea occurs. Nevertheless, few primary care physicians routinely order pulmonary function tests for their patients who smoke or for patients with mild-to-moderate dyspnea
  7. Chilaiditi syndrome is a rare form of bowel obstruction caused by the interposition of the colon or small bowel into the hepatodiaphragmatic space. This condition usually resolves with conservative management, but in this case report, the patient had a closed-loop small bowel obstruction that required surgical intervention. Reference

Intestinal Complications after Roux-en-Y Gastric Bypass

  1. A closed-loop obstruction may develop when the bowel twists around on itself, isolating the looped section of the bowel and obstructing the portion above it. With a strangulated obstruction, there is decreased blood flow to the bowel that, if not relieved, will develop into an incarcerated obstruction, and the bowel will become necrotic
  2. al distension is common in the late stages of colon obstruction. During the closed-loop obstruction, the bowel distension will become obvious, and asymmetric local expansion can often be seen in the abdo
  3. al CT was performed that showed a subhepatic collection with anfractuous borders, a thick wall and an airfluid level in the surgical bed, suggestive of abscess. In a second reading of the CT, a closed loop small bowell obstruction (CL-SBO) with signs of ischemia was found
  4. Closed-loop large-bowel obstruction Strategies to manage a closed-loop large-bowel obstruction include bowel resection, with or without the formation of a colostomy and colonic stenting. Stenting is associated with complications including migration, further obstruction and perforation, and may require further definitive management
  5. Closed loop obstructions have higher complication rates for ischemia and perforation, and for a septic presentation. Many are diagnosed in the OR. Signs to look for on CT are a distended, fluid-filled bowel loop in C or U shape, the whirl sign (abdomen bowel rotated around its mesentery resembling a whirlpool), the beak sign.
  6. Closed-loop obstructions are usually treated as surgical emergencies because of the high risk of strangulation. Strangulation can occur with simple or closed-loop obstruction but is more frequent in the latter. 2 CT findings suggesting strangulation can be classified as mural or extramural (Table 7)
  7. In closed-loop obstruction, an intestinal segment is occluded at two points.Common forms of closed loops include an incarcerated hernia, in which a loop of the intestine is compressed at both ends within a hernial sac, and volvulus, in which a loop of intestine is mechanically compressed at both ends because of a twist in the supporting mesentery

Complications:-Dehydration-Bowel perforation- especially in closed loop obstruction i.e. obstruction at two points, such as a sigmoid volvulus with distended proximal colon and a competent ileocaecal valve. Even with simple obstruction, with increased distension, the intestinal wall blood supply becomes impaired and mucosal ulceration and bowel. Volvulus - Volvulus is an abnormal twisting of a segment of bowel around itself. This twisting motion typically produces a closed loop of bowel with a pinched base, leading to intestinal obstruction. In Western countries, volvulus is most common among people over age 65, and these patients often have a history of chronic (long-lasting) constipation studies. A closed-loop obstruction occurs when a segment of intestine, usually small bowel, is obstructed in two locations, creating a segment with no proximal or distal outlet. Only a short segment of intestine may be distended because of minimal abdominal distention. Closed-loop obstruction can rapidly lead to complications (ischemia

Radiologists and surgeons should be aware of a closed-loop obstruction associated with colon cancer because this is an urgent surgical situation that can lead to a perforated colon. Fig. 2 75-year-old woman with closed-loop obstruction secondary to adenocarcinoma of ascending colon and she had competent ileocecal valve Closed-loop obstruction is at risk of strangulation and is mostly caused by mesenteric torsion, volvulus, or hernia. It can be dilated when one dilated bowel loop obstructed at a single point, i.e., a closed loop, and another dilated bowel loop proximal to the obstructive site are depicted on CT CLOSED LOOP OBSTRUCTION • Two points along the course of the gut are obstructed at a single site. • Most often found with an adhesive band and occasionally by an internal or external hernia. • C-shaped, U-shaped, or coffee bean configuration of the bowel loop with converging toward the torsion. • Beak or whirl sign at the site of. A biliary obstruction is a blockage of the bile ducts. The bile ducts carry bile from the liver and gallbladder through the pancreas to the duodenum, which is a part of the small intestine

Closed-loop obstruction is a relatively uncommon subcategory of small-bowel obstruction; however, it is associated with a high risk of vascular impairment and is, therefore, important to diagnose accurately. Closed-loop obstruction is often caused by conditions such as internal hernias, congenital bands, postoperative adhesions, and malrotation Closed-loop obstruction. CT. scan through the pelvis shows three loops of mildly dilated small-bowel with a thickened small-bowel wall with increased attenuation. The prominent mesenteric vascularity of the middle loop is the result of arterial inflow, but no venous outflow, in a closed-loop obstruction. Figure 5.17 Most closed-loop obstructions (75%) are caused by adhesions. A closed-loop obstruction occurs when a loop of bowel is not decompressed by the caudal passage of gas and fluid. This obstruction may be associated with a U-shaped distended loop of small bowel. This loop may be fixed and does not change position over time In the surgical group, the causes of surgery were the failure of conservative management (59%), ischemic signs (intractable pain, leukocytosis, or unstable vital signs) during conservative management (30%), and a CT finding of ischemia or closed-loop obstruction at diagnosis (11%)

Intestinal Malrotation. III. Pathophysiology: Process (Occurs quickly in closed loop obstruction) Obstruction forms in either Small Bowel (much more common) or Large Bowel. Bowel dilates proximal to obstruction. Flatus and Bowel Movement s cease. Dehydration results from Vomiting, minimal absorption, and bowel edema Closed loop obstruction in sigmoid volvulus leading to gangrene and other complications are known. Gangrenous changes are confined only to the bowel involved in the volvulus. To our knowledge, gangrene involving the entire large bowel secondary to a sigmoid volvulus has not been reported Findings on the CT scan that predict the need for operative management, include a closed-loop obstruction, markers of bowel ischemia (mesenteric edema, free intraperitoneal fluid), and the small bowel feces sign, and additional radiological scores can be used to predict the need for surgery [37, 40] A ureteral obstruction is a blockage in one or both of the tubes (ureters) that carry urine from your kidneys to your bladder. Ureteral obstruction can be curable. However, if it's not treated, symptoms can quickly move from mild — pain, fever and infection — to severe — loss of kidney function, sepsis and death

A volvulus is when a loop of intestine twists around itself and the mesentery that supports it, resulting in a bowel obstruction. Symptoms include abdominal pain, abdominal bloating, vomiting, constipation, and bloody stool. Onset of symptoms may be rapid or more gradual. The mesentery may become so tightly twisted that blood flow to part of the intestine is cut off, resulting in ischemic bowel Rotation can be clockwise or counterclockwise. Once the volvulus has a 360° twist, then a closed loop obstruction is produced. Fluid and electrolyte shifts result from fluid secretion into the closed loop producing an increase in pressure and tension on the colonic wall that will eventually impair colonic blood supply Closed loop obstruction is a specific type of obstruction in which two points along the course of a bowel are obstructed at a single location thus forming a closed loop. Usually this is due to adhesions, a twist of the mesentery or internal herniation. In the large bowel it is known as a volvulus
