These patients can be fed after the endoscopy and treated with oral acid suppression medication; they do not require continued hospitalization unless indicated for other medical problems herbs chicken soup generic 400 mg hoodia otc. Therefore the risk of rebleeding is high herbs chips purchase hoodia with american express, and definitive hemostasis with standard techniques is usually required in patients with varices or ulcers with major stigmata herbals interaction with antihistamines buy generic hoodia on line. Current guidelines recommend utilization of hemospray as a stopgap or adjunct technique herbs good for hair generic hoodia 400mg with visa. Testing for Hp Infection In a patient with a bleeding gastric or duodenal ulcer, endoscopic mucosal biopsy specimens of the normal-appearing antrum and mid-body greater curvature should be obtained to assess for the presence of Hp infection. Biopsy specimens can be obtained safely after successful endoscopic hemostasis, but bleeding reduces the sensitivity of rapid urease testing. Therefore stool antigen and other tests for Hp infection are recommended (see Chapter 52). The rebleeding rate in the omeprazole-treated group was 11% compared with 36% in the placebo-treated group (P < 0. Second-Look Endoscopy Routine repeat, or second-look, endoscopy 24 hours after initial endoscopic hemostasis, with additional endoscopic hemostasis if persistent high-risk endoscopic stigmata are found, has been proposed as a way to improve patient outcomes. Rebleeding After Endoscopic Treatment the risk of rebleeding from peptic ulcers, which started bleeding in the outpatient setting and required endoscopic hemostasis, is greatest in the first 72 hours after diagnosis and treatment. The difference between ulcer hemorrhage that starts in the outpatient setting and hemorrhage that starts in the inpatient setting is substantial (Table 20. Further studies are warranted in this high-risk group to define optimal management. A large, well-designed, randomized trial from Hong Kong found that when endoscopic hemostasis is repeated in patients with hemodynamically significant rebleeding after initial endoscopic hemostasis, 73% of patients achieve sustained hemostasis and do not require surgery. Factors that predicted failure of endoscopic retreatment included an ulcer size of at least 2 cm and hypotension on initial presentation. This new treatment has the potential to reduce the need for surgery or angiography for recurrent ulcer bleeding. Surgery should also be considered if the endoscopist does not feel comfortable treating a large or pulsating visible vessel After successful endoscopic treatment and recovery from sedation, the patient can be started on a liquid diet, with subsequent advancement of the diet. For patients who have been on and need to continue antiplatelet agents or an anticoagulant, a cardiologist or vascular physician should be consulted to help determine whether, and for how long, these agents can be held. Intermediate-Risk Stigmata Patients with flat spots and arterial blood flow detected underneath, those with oozing bleeding from an ulcer and no other stigmata Angiography, Surgery, and Over-the-Scope Hemoclips Patients with recurrent bleeding despite 2 sessions of endoscopic hemostasis can be considered for angiographic embolization or surgical therapy. Antibiotic therapy does not have to *One point signifies a healthy person; 5 points signifies high likelihood of mortality within 24 hr. In patients who are found to have an Hp-induced ulcer, confirmation of the eradication of Hp after treatment is recommended (see Chapter 52). If the patient is also positive for Hp, the organism should be eradicated with standard therapy (see Chapter 52). Endoscopy with biopsies and brushings is critical for making these diagnoses and determining the appropriate pharmacologic therapy (see Chapter 45). Ulcer Hemorrhage in Hospitalized Patients Hemorrhage from an ulcer or erosions in hospitalized patients typically falls into 2 categories. Diffuse oozing is common, and patients have a poor prognosis and high rebleeding rate, often related to impaired wound healing and multiple organ failure. The 2 main risk factors are severe coagulopathy and mechanical ventilation for longer than 48 hours. By contrast, focal inpatient ulcer hemorrhage often requires endoscopic hemostasis for severe hemorrhage In areas of the world where the population is at intermediate risk for gastric cancer, 2% to 4% of repeat upper endoscopies to confirm ulcer healing have been reported to disclose gastric cancer. It is usually located in the gastric fundus, within 6 cm of the gastroesophageal junction, although lesions in the duodenum, small intestine, and colon have been reported. The cause is unknown, and congenital and acquired (related to mucosal atrophy or an arteriolar aneurysm) causes are thought to occur (see Chapter 38). Dieulafoy lesion can be difficult to identify at endoscopy because of the intermittent nature of the bleeding; the overlying mucosa may appear normal if the lesion is not bleeding. Mallory-Weiss Tears Mallory-Weiss tears are mucosal or submucosal lacerations that occur at the gastroesophageal junction and usually extend distally into a hiatal hernia. Patients generally present with hematemesis or coffee-ground emesis and a history of nonbloody vomiting followed by hematemesis, although some patients do not recall vomiting. The tear is thought to result from increased intra-abdominal pressure, in combination with a shearing effect caused by negative intrathoracic pressure above the diaphragm, which is often related to vomiting. Mallory-Weiss tears have been reported in patients who vomit while taking a bowel purge before colonoscopy. A retroflexed view in the stomach may provide better visualization than a forward view. Usually, the bleeding is self-limited and mild, but occasionally it can be severe, especially in patients with esophageal varices or coagulopathies. Mucosal (superficial) Mallory-Weiss tears can start healing within hours and can heal completely within 48 hours. The management of patients with esophageal varices caused by portal hypertension who also have a Mallory-Weiss tear should be targeted toward the esophageal varices, with esophageal band ligation or variceal sclerotherapy (see later and Chapter 92). The tumors are usually large, ulcerated masses in the esophagus, stomach, or duodenum. Note that the tear starts at the gastroesophageal junction (long arrow) and extends distally into the hiatal hernia (short arrow). External beam radiation can provide palliative hemostasis for patients with bleeding from advanced gastric or duodenal cancer (see Chapter 54).

In patients with dyspepsia, additional clinical investigations may identify underlying organic disease that is likely to cause the symptoms. In these subjects, symptoms are attributable to an organic cause of dyspepsia (Box 14. The term uninvestigated dyspepsia refers to dyspeptic symptoms in persons in whom diagnostic investigations have not yet been performed and in whom a specific diagnosis that explains the dyspeptic symptoms has not been determined. Systematic studies indicate that 20% to 25% of patients with dyspeptic symptoms in Western societies have erosive esophagitis, 20% are estimated to have endoscopy-negative reflux disease, 10% have peptic ulcer, 2% have Barrett esophagus, and 1% or less have malignancy. In the literature, dyspepsia is often broadly defined as pain or discomfort centered in the upper abdomen1, 2 but may include multiple and varying symptoms such as epigastric pain, postprandial fullness, early satiation, anorexia, belching, nausea and vomiting, upper abdominal bloating, and even heartburn and regurgitation. With time, definitions of dyspepsia have evolved to become more restrictive and focused on symptoms that are thought to arise from the gastroduodenal region, not the esophagus. Intolerance to Food or Drugs Contrary to popular beliefs, ingestion of specific foods However, the frequency of peptic ulcer in persons with dyspepsia is only 5% to 10%.
Pain may be exacerbated by lying recumbent and relieved by sitting or leaning forward herbs chicken soup generic hoodia 400mg line. Severe abdominal pain also may be seen with aortic dissection as the splanchnic vessels become compromised and acute intestinal ischemia develops herbs names 400mg hoodia fast delivery. Less commonly herbs native to outland purchase hoodia in united states online, the aneurysm may communicate with the peritoneal cavity wholesale herbs discount 400mg hoodia with amex, in which case hemorrhagic shock develops rapidly. Indeed, many of these patients will have a "herald bleed" followed by massive hemorrhage several hours or days later. In a large population of patients with small aneurysms (average initial size of 4 cm) studied over an average of 3. In elective cases, preoperative angiography is useful to demonstrate additional vascular disease Symptoms if present are left upper quadrant or epigastric pain that may radiate to the left shoulder. There is a female to male predominance of 3 to 4:1, and it is associated with pregnancy. Similarly, increased splenic blood flow is considered the cause of splenic artery aneurysms in portal hypertension. Aneurysmal rupture occurs in less than 2% of patients except for in pregnant women in whom the risk of rupture is much higher. More than 95% of aneurysms in pregnant woman are diagnosed after rupture and are associated with a 75% maternal and 95% fetal mortality rate. It is said that the period in which the bleeding is localized in the lesser sac allows time for surgical intervention in about 25% of patients. Mortality after emergency surgery is as high as 40%, compared with a very low mortality rate after elective repair. A symptomatic aneurysm or an aneurysm of any size in a pregnant woman or a woman planning to get pregnant should undergo repair before pregnancy. If the location of the aneurysm is proximal and it is larger than 2 cm, surgical management should be considered and would include resection and an end to end vascular repair; if the location is distal or involves the hilum, splenectomy is recommended. For patients with portal hypertension, embolization is preferred because the extensive collateral circulation makes surgery more difficult. Complications of embolization include splenic infarction and reperfusion of the aneurysm which can occur in 5% to 20% of patients. On physical exam, a bruit may be heard on auscultation, but an abdominal mass is rarely palpable because the aneurysms are small. In general, treatment is considered if the diameter of the aneurysm is greater than 2 cm even if asymptomatic. Treatment options include embolization, surgical repair, or endovascular stenting. Ligation can be performed followed by aortohepatic bypass or direct aortic reimplantation. If the aneurysm ruptures, intervention may include ligation or percutaneous transcatheter embolization. Aneurysm-related thrombus or dissection can occur, which can cause symptoms of intestinal ischemia. In recent series, the common causes include atherosclerosis, polyarteritis nodosa, pancreatitis, biliary tract disease, neurofibromatosis, and trauma. They were so named by Sir William Osler because their appearance reminded him of fungi (mykes, fungus). In the past, mycotic aneurysms were most commonly caused by septic emboli from bacterial endocarditis. Other important risk factors include contiguous spread from adjacent infectious processes, arterial manipulation, and immunocompromise Salmonella (especially Salmonella choleraesuis) and Staphylococcus are the most common infecting organisms. Early in the course, symptoms of mycotic aneurysms are nonspecific; fever, chills, and abdominal pain typically occur later. Diagnosis is by imaging the vasculature: mycotic aneurysms typically are lobulated and saccular. The destructive process can develop quickly, leading to rapid expansion and rupture. Life-long suppressive oral antibiotic therapy also has been used to prevent prosthetic graft infection. Newer surgical techniques, including the use of endovascular grafts, nonabsorbable sutures, antibiotics, strict hemostasis, and coverage of suture lines with retroperitoneal tissue and peritoneum, may reduce the frequency of fistula formation. Primary aortoenteric fistulas develop in the absence of prior aneurysm repair and are associated with atherosclerosis, infection (most commonly Salmonella spp. Telangiectasias of varying size and shape in the proximal gastric body (B), antrum (C). Primary aortoenteric fistulas are less common than secondary aortoenteric fistulas, with an incidence of 0. Severe hemorrhage is unusual before the fourth decade and has a peak incidence in the sixth decade. Bleeding is intermittent and chronic and may be severe; patients may receive more than 60 transfusions in a lifetime. Telangiectasias usually are present on the lips, oral and nasopharyngeal membranes, tongue, and periungual areas; lack of involvement of these sites casts suspicion on the diagnosis.

Sponge changes are performed every 3 to 5 days until closure of the cavity and defect euphoric herbs hoodia 400 mg visa. Initial attempts of nonsurgical interventions do not preclude surgery and may spare some patients having to undergo highly morbid procedures herbals vaginal dryness order hoodia once a day. More complex fistulas may require surgery to remove mesh or other foreign bodies before spontaneous closure can occur or definitive surgery is undertaken. The goal of surgical therapy is to resolve infection and restore intestinal continuity-usually requiring resection. In the case of the postoperative enterocutaneous fistula, further surgery should occur either in the favorable "window period," 7 to 12 days after laparotomy or deferred at least 6 weeks thereafter to allow improvement of intra-abdominal inflammation and adhesions. If operative intervention is performed beyond the window period, it is often doomed to fail. Moreover, these patients have an increased likelihood of developing additional enterotomies. In the setting of sepsis, the general consensus in the literature is to wait at least 6 weeks after stabilization and resolution of sepsis, with many advocating for longer waiting periods. Different techniques have been used in the surgical treatment of fistulas, and some success has been seen with innovative techniques such as pedicled flaps. The typical setting for septic complications is provided by complex fistulas for which there is inadequate or uncontrolled drainage. In this setting, pooling of enteric contents occurs within the abdominal cavity and acts as a nidus of infection. Therefore, as noted, aggressive attempts must be made to ensure that fistulous drainage is well controlled. Often, patients who are terminally ill secondary to malignancy forgo further operative procedures. The rate of spontaneous closure of fistulas varies in the literature from 15% to 71%. Of those fistulas that close spontaneously, about 90% will do so within 30 days of stabilization and control of sepsis. Important factors for resolution are control of sepsis, control of fistula output, and nutritional support. Although innovative therapy and supportive care have resulted in improving spontaneous closure rates, management of these difficult problems requires a multidisciplinary approach that includes a nutritional support service, an enterostomal therapist, a surgeon, an interventional radiologist, and a gastroenterologist.
