Hemorrhagic radiation gastritis successfully treated with repeated intra-arterial steroid infusions

Intra-arterial steroid infusion therapy has previously been shown to be effective for inflammatory bowel disease; however, few cases in which it has been used for the treatment of hemorrhagic radiation gastritis have been reported. We report the case of a 70-year-old Japanese man with hemorrhagic radiation gastritis induced by radiation therapy for para-aortic lymph node metastases of hepatocellular carcinoma. Two months after completing radiation therapy, acute persistent bleeding occurred in the gastric irradiation area. Although argon plasma coagulation was performed five times over a month, the bleeding continued and the patient showed persistent anemia that required 50 units of blood transfusion. Finally, the patient was given intra-arterial steroid infusions through the right gastric artery and the right gastroepiploic artery. After three intra-arterial steroid infusions, the melena stopped, and the anemia no longer progressed. Hemorrhagic radiation gastritis was successfully treated with repeated intra-arterial steroid infusions through the regional vessels to the gastric mucosa. Repeated intra-arterial steroid infusions could be a clinically useful option for the treatment of intractable bleeding from radiation gastritis.     

Treatment of radiation-induced hemorrhagic gastritis with prednisolone: A case report

Radiation-induced gastritis is an infrequent cause of gastrointestinal bleeding.It is a serious complication arising from radiation therapy,and the standard treatment method has not been established.The initial injury is characteristically acute inflammation of gastric mucosa.We presented a 46-year-old male patient with hemorrhagic gastritis induced by external radiotherapy for metastatic retroperitoneal lymph node of hepatocellular carcinoma.The endoscopic examination showed diffuse edematous hyperemicmucosa with telangiectasias in the whole muscosa of the stomach and duodenal bulb.Multiple hemorrhagic patches with active oozing were found over the antrum.Anti-secretary therapy was initiated for hemostasis,but melena still occurred off and on.Finally,he was successfully treated by prednisolone therapy.We therefore strongly argue in favor of perdnisolone therapy to effectively treat patients with radiation-induced hemorrhagic gastritis.     

Growth hormone used to control intractable bleeding caused by radiation-induced gastritis

Intractable bleeding caused by radiation-induced gastritis is rare. We describe a 69-year-old man with intractable hemorrhagic gastritis induced by postoperative radiotherapy for the treatment of esophageal carcinoma. Although anti-secretory therapy with or without octreotide was initiated for hemostasis over three months, melena still occurred off and on, and the patient required blood transfusions to maintain stable hemoglobin. Finally growth hormone was used in the treatment of hemorrhage for two weeks, and hemostasis was successfully achieved. This is the first report that growth hormone has been used to control intractable bleeding caused by radiation-induced gastritis.     

An exceptional postoperative gastric tube bleeding after esophageal resection for cancer

A case of gastric tube bleeding after an Ivor-Lewis esophagectomy with gastroesophageal anastomosis is reported. During the early postoperative course, the patient had a gastric tube stasis that improved progressively. The subsequent onset of a serious and intermittent hematemesis, which was endoscopically deemed to be the result of a hemorrhagic gastritis, required multiple blood transfusions. The evolution to a severe hemodynamic instability obliged us to reoperate on the patient. During surgery, a band-related obstruction of the first jejunal loop with local signs of vascular hypertension was noted. As soon as the obstruction was solved, the gastric bleeding stopped. The authors discuss the clinical aspects and physiopathology of the gastric tube bleeding and, in particular, they evaluate the influence of the intestinal obstruction with vascular involvement on the development of this exceptional and severe complication.     

Endoscopic examination of the upper gastrointestinal tract in infancy

Forty endoscopic examinations of the upper gastrointestinal tract were performed in 38 infants with an age range from 2 days to 12 months. The main indications were upper gastrointestinal bleeding, chronic intractable vomiting, and small intestinal biopsy. Duodenal ulcer, hemorrhagic gastritis, and gastric erosions were the most common causes of upper gastrointestinal bleeding in infancy. An acute viral infection with fever, aspirin ingestion, and diarrhea frequently preceded gastrointestinal bleeding from duodenal ulcer and gastric erosion. Four of the 27 bleeding patients demonstrated no abnormality endoscopically.     

Gastric venous congestion and bleeding in association with total pancreatectomy

Background

Gastric venous congestion and bleeding in association with total pancreatectomy (TP) were evaluated.

Methods

Thirty‐eight patients of TP were retrospectively analyzed. TP was classified as TP with distal gastrectomy (TPDG), pylorus‐preserving TP (PPTP), subtotal stomach‐preserving TP (SSPTP), and TP with segmental duodenectomy (TPSD).

Results

Portal vein or superior mesenteric vein resection and reconstruction was performed in 24 patients (62.2%). Gastric bleeding occurred immediately after tumor resection in one of eight patients who underwent SSPTP, and urgent anastomosis between the right gastroepiploic and left ovarian vein stopped the bleeding. Another case of gastric bleeding was observed a few hours after TP in one of nine patients who underwent PPTP, and hemostasis was achieved after conservative therapy. Gastric bleeding was not observed in 16 patients who underwent TPDG and five who underwent TPSD. Some patients underwent preservation of gastric drainage veins (left gastric vein, right gastric vein, or right gastroepiploic vein). Neither patient with bleeding underwent preservation of a gastric drainage vein.

Conclusions

To preserve the subtotal or whole stomach when performing TP, one of the gastric drainage veins should undergo preservation or reconstruction, and anastomosis between the right gastroepiploic vein and left ovarian vein may be beneficial.     

Ethanol-derived Microbial Production of Carcinogenic Acetaldehyde in Achlorhydric Atrophic Gastritis

Background: Acetaldehyde is a local carcinogen in the digestive tract in humans. Atrophic gastritis leads to microbial colonization of the stomach, which could enhance microbial production of acetaldehyde from ethanol. The aim of the study was to study microbial ethanol metabolism and acetaldehyde production in the stomach of achlorhydric atrophic gastritis patients. Methods: For the in vivo study, glucose or ethanol was infused via a nasogastric tube to the stomach of seven achlorhydric atrophic gastritis patients and five healthy controls. Gastric juice samples for ethanol and acetaldehyde determinations and microbial analysis were obtained at 30 and 60 min after the infusions. For the in vitro study, gastric juice samples from 14 atrophic gastritis patients and 16 controls were obtained during gastroscopy, whereafter the samples were incubated for 2 h with 1% ethanol at 37 °C and acetaldehyde was determined. Results: Minor endogenous ethanol and acetaldehyde concentrations were detected after glucose infusion in the gastric juice of four atrophic gastritis patients. After ethanol infusion, the mean intragastric acetaldehyde level of the atrophic gastritis patients was 4.5-fold at 30 min and 6.5-fold at 60 min compared to controls. In vitro, the difference between the study groups was even higher, 7.6-fold. A vast selection of oral bacterial species and some Enterobacteriaceae and yeasts were presented in the gastric juice of atrophic gastritis patients. Conclusions: Microbial ethanol metabolism leads to high intragastric acetaldehyde levels after ethanol drinking in achlorhydric atrophic gastritis patients. This could be one of the factors responsible for enhanced gastric cancer risk among atrophic gastritis patients.     

Prospective endoscopic follow-up results of reconstructed gastric tube

BACKGROUND/AIMS: Recent advances in the treatment of esophageal cancer have afforded better prognosis for patients. Despite the increased need to monitor the progress of patients with reconstructed digestive tracts over the long-term, no reliable prospective studies have yet been conducted. This prospective study determined secondary disease of the reconstructed gastric tube after esophagectomy for esophageal cancer. METHODOLOGY: One hundred and fourteen patients who underwent esophagectomy and reconstructed gastric tube via the posterior mediastinal route between April 1992 and March 1999 at Akita University Hospital, were followed up. Follow-up endoscopy was carried out once a year to determine the incidence and characteristics of secondary disease of the reconstructed gastric tube. RESULTS: Fifty-four (47%) patients were found to have secondary gastric abnormalities. Of these, 4 patients (3.5%) had carcinoma of the gastric tube, 12 patients (10.5%) had benign gastric tumor, 7 patients (6.1%) had gastric ulcers, and 40 patients (35.1%) had erosive or hemorrhagic gastritis. Three patients found to have early gastric cancer upon periodic follow-up endoscopy underwent successful complete resections. CONCLUSIONS: Annual follow-up endoscopy is vital to the detection of early, curative secondary gastric cancer and ulceration in patients following esophagectomy for esophageal cancer.     

Ethanol-derived microbial production of carcinogenic acetaldehyde in achlorhydric atrophic gastritis

Modulation of gastric pH by continuous gastric and jejunal infusion of cimetidine

We studied the effect of gastric versus jejunal tube feedings on gastric pH and evaluated the acid-inhibiting effects of continuous gastric and jejunal infusions of cimetidine. pH was monitored by an intragastric pH probe in 19 gastrostomy and 13 jejunostomy patients during fasting, continuous infusions of Osmolyte, cimetidine, and simultaneously Osmolyte and cimetidine. Gastric Osmolyte increased fasting pH from a mean of 1.32 to 2.78 (P less than 0.01), while jejunal Osmolyte did not (pH 1.02). Continuous gastric infusion of cimetidine maintained a high gastric pH (5.06) in 17 of 19 patients. Jejunal cimetidine also achieved therapeutic serum levels and raised gastric pH to 4.81 in nine of 13 patients. We conclude that the persistently low gastric pH during jejunostomy tube feeding may play a major role in the upper gastrointestinal bleeding previously observed in such patients and that continuous gastric and jejunal cimetidine infusions effectively raise and sustain a high gastric pH.     

Role of radiation therapy in gastric adenocarcinoma

Outcomes in patients with gastric cancer in the United States remain disappointing, with a five-year overall survival rate of approximately 23%. Given high rates of local-regional control following surgery, a strong rationale exists for the use of adjuvant radiation therapy. Randomized trials have shown superior local control with adjuvant radiotherapy and improved overall survival with adjuvant chemoradiation. The benefit of adjuvant chemoradiation in patients who have undergone D2 lymph node dissection by an experienced surgeon is not known, and the benefit of adjuvant radiation therapy in addition to adjuvant chemotherapy continues to be defined. In unresectable disease, chemoradiation allows long-term survival in a small number of patients and provides effective palliation. Most trials show a benefit to combined modality therapy compared to chemotherapy or radiation therapy alone. The use of pre-operative, intra-operative, 3D conformal, and intensity modulated radiation therapy in gastric cancer is promising but requires further study. The current article reviews the role of radiation therapy in the treatment of resectable and unresectable gastric carcinoma, focusing on current recommendations in the United States.     

Indocyanine green fluorescence and three-dimensional imaging of right gastroepiploic artery in gastric tube cancer

A 79-year-old male was admitted to our hospital for the treatment of cancer of the gastric tube.Gastrointestinal examination revealed a T1 b Union for International Cancer Control(UICC) tumor at the pyloric region of the gastric tube.Laparotomy did not reveal infiltration intothe serosa,peritoneal dissemination,regional lymph node swelling,or distant metastasis.We performed a distal gastrectomy preserving the right gastroepiploic artery by referencing the preoperative three-dimensional computed tomoangiography.We also evaluated the blood flow of the right gastroepiploic artery and in the proximal gastric tube by using indocyanine green fluorescence imaging intra-operatively and then followed with a gastrojejunal anastomosis with Roux-en-Y reconstruction.The definitive diagnosis was moderately differentiated adenocarcinoma of the gastric tube,pT 1bN 0M0,pS tage IA(UICC).His postoperative course was uneventful.Three-dimensional computed tomographic imaging is effective for assessing the course of blood vessels and the relationship with the surrounding structures.Intraoperative evaluation of blood flow of the right gastroepiploic artery and of the gastric tube in the anastomotic portion is very valuable information and could contribute to a safe gastrointestinal reconstruction.     

Therapeutic effect of intraarterial prednisolone injection in severe intestinal Behçet's disease

A 64-year-old woman with severe intestinal Beh?et's disease who was unresponsive to conventional therapies, including intensive intravenous steroid injections, underwent intraarterial steroid injection therapy. After the infusion of prednisolone into the mesenteric arteries, her colon ulcers improved markedly, and the frequency of bloody stools decreased immediately. The present case suggests that intraarterial steroid injection therapy may be potentially useful in severe intestinal Beh?et's disease.     

Endoscopic comparison of two cases: distal resection of reconstructed gastric tube

Recently, with the improvement of the prognosis of esophageal cancer, subsequent gastric cancer has increased. However, the standard surgical treatment for such patients has not been established as of yet. Since the patient's physical condition is relatively poor after Ivor-Lewis esophagectomy, it is important that surgical strategies must be decided according to both physical and cancerous conditions. Hence, various surgical procedures have been reported to date. The authors experienced two cases with cancer occurring in the reconstructed gastric tube after Ivor-Lewis esophagectomy. One was subsequent primary gastric cancer, and the other was metastatic gastric cancer. Distal resection of the gastric tube including the dissection of the right gastroepiploic vessels was carried out in both cases. Vascular reconstruction by utilizing microsurgery technique was attempted for each case, but failed in one case. After surgery, four sessions of endoscopic examinations were carried out. In the early period, we could identify mucosal ischemic change in the remnant gastric tube in the case without successful vascular reconstruction. On the contrary, no ischemic change was revealed in the other with successful vascular reconstruction. Hence, we came to the conclusion that vascular reconstruction must be added to the cases, which undergo distal resection of the reconstructed gastric tube with regional vascular dissection.     

The vascularization of a gastric tube as a substitute for the esophagus is affected by its diameter.

The stomach is used for reconstruction of the upper gastrointestinal tract after esophageal resection for cancer. The whole stomach can be used, but also a wide or narrow gastric tube can be constructed. Short-term functional results are superior after use of a narrow tube. Healing of the cervical esophagogastrostomy can be impaired, leading to leakage and stricture. The decreased vascularization at the site of the anastomosis may be one reason. It was hypothesized that the quality of the vascularization of the gastric tube, used as a substitute for the oesophagus after esophagectomy, depends on its diameter. The vascularization of postmortem specimens was studied using angiography. Whole stomachs (3), wide (3) and narrow gastric tubes (3) were constructed. In a patient with an anastomotic stricture of a narrow tube with a cervical esophagogastrostomy vascularisation was evaluated by angiography. After infusion of contrast through the supplying arteries, the whole stomachs and wide gastric tubes showed adequate vascularization, whereas the narrow gastric tube showed poor vascularization especially at the site of the anastomosis. In narrow gastric tubes, the right gastroepiploic artery was the only feeding artery. In the patient's angiography, a limited contrast visualization of the proximal end of the gastric tube could be demonstrated. Although a narrow gastric tube is favoured by some surgeons, the use of whole stomach or a type of gastric tube with preservation of the right gastric artery may lead to a better anastomotic healing.     

Gastric lesions in portal hypertension: inflammatory gastritis or congestive gastropathy?

This paper reports the incidence and natural history of macroscopic gastritis in a series of 127 consecutive patients with portal hypertension of various aetiologies. Gastritis was observed endoscopically in 65 patients (51%) and was of two main types. Twenty eight patients had severe or persistent gastritis which caused clinically significant bleeding on 80 occasions and accounted for 25% of the bleeds from all sources. The remainder had mild gastritis. The presence of gastritis seemed to be independent of the severity of liver disease or the degree of rise of wedged hepatic venous pressure and there was no difference in age, sex, or drugs prescribed in patients with or without gastritis. The mean follow up period and the mean number of sclerotherapy treatments was significantly greater (p less than 0.005) in patients with gastritis. Full thickness gastric biopsies in seven surgical patients and 11 autopsy specimens showed dilated and tortuous submucosal veins. Endoscopic biopsies in 14 patients showed vascular ectasia in the mucosal layer which was in excess of the degree of inflammatory infiltrate. Gastritis occurred in patients with portal hypertension of all common aetiologies and the clinical and pathological evidence supports the contention that it reflects a congested gastric mucosa and should be renamed congestive gastropathy. As injection sclerotherapy improves survival from variceal bleeding congestive gastropathy may become more common. The response to conventional ('anti-erosive') therapy is poor and measures aimed at reducing the gastric portal pressure may be the only effective means of treating this condition.     

Effect of simulated intragastric haemorrhage on gastric acid secretion, gastric motility, and serum gastrin.

The majority of upper gastrointestinal bleeds stop spontaneously despite the low pH and proteolytic activity of gastric juice which inhibit coagulation and platelet aggregation. In order to investigate this paradox six healthy male volunteers received intragastric infusions of 160 ml autologous venous blood or 160 ml egg white acting as control in random order on separate days. Basal acid output was calculated before infusion, net acid secretion and gastric volume emptied were calculated after intragastric infusions. Serum gastrin concentrations were also measured before and after intragastric infusions and expressed as the integrated gastrin response. Basal acid output (mmol/h) was 4.7 (1.9) (mean (SEM)) before egg white infusion and 5.9 (2.6) before venous blood infusion. After egg white infusion net acid secretion (mmol/20 min) increased to 5.6 (3.1) compared with 2.3 (1.3) after venous blood infusion (p less than 0.05). The gastric volume emptied (ml/20 min) was less after venous blood infusion at 105 (28) compared with 321 (66) after egg white infusion (p less than 0.03). Integrated gastrin response was similar after venous blood and egg white infusion. When compared with an equivalent protein meal intragastric blood stimulates less acid secretion and delays gastric emptying. This effect may facilitate haemostasis after gastric bleeding.     

Argon plasma coagulation is an effective treatment for refractory hemorrhagic radiation proctitis

INTRODUCTION: Chronic radiation proctitis complicating pelvic radiotherapy can be debilitating. It commonly presents with rectal bleeding, which can be difficult to control. Medical management of hemorrhagic radiation proctitis is not very successful, although surgery carries high risks. Thus, endoscopic treatments are preferred. The aim of this study is to assess the efficacy of argon plasma coagulation applied endoscopically to treat hemorrhagic radiation proctitis that has been refractory to topical formalin therapy. METHODS: Twelve patients who had ongoing bleeding from radiation proctitis, after previously failed formalin therapy, underwent endoscopic treatment using argon plasma coagulation. The efficacy of treatment was assessed by grading the frequency and severity of bleeding (0–4, 0 being no bleeding), hemoglobin level, and transfusion requirements. RESULTS: At a median follow-up of 11 months, ten patients (83 percent) had a significant reduction in the severity and frequency of bleeding, with complete cessation in six (50 percent). The presence of coexistent radiation-induced sigmoiditis in two patients was associated with reduced but persistent bleeding, because of difficulty in targeting the bleeding sites in the sigmoid colon. The median number of treatment sessions per patient was two (range, 1–3), with the number of sessions correlated with the extent of the proctitis. All patients had an improvement in their hemoglobin level, with the mean increasing from 11.2 to 12.3 g/dl. In the six months before starting therapy, all patients had been taking iron supplements, and four had required blood transfusions (median 3 units, range, 2–6). Iron supplements were ceased four weeks after the completion of therapy in all cases, and no further transfusions were required during the study period. None of the patients experienced any significant side effects or complications. CONCLUSIONS: Argon plasma coagulation is an effective and safe treatment for hemorrhagic radiation proctitis that has been refractory to topical formalin therapy.     

Omentoplasty for cervical esophagogastrostomy following radical esophagectomy with three-field dissection

BACKGROUND/AIMS: Anastomotic leakage is the main cause of postoperative mortality and incidence of which, following three-field lymph node dissection, is around 30%. The study was undertaken to investigate the role of omentoplasty to reinforce cervical esophagogastrostomy with the expectation of lowering the rate of anastomotic leakage after radical esophagectomy with three-field lymph node dissection. METHODOLOGY: Between July 1995 and Dec 1997, a total of 32 patients underwent total thoracic esophagectomy with three-field lymph node dissection and cervical esophagogastrostomy. Eleven patients were stage IIA, 3 stage IIB, 5 stage III and 13 stage IV. After radical esophagectomy and lymph node dissection, several omental branches of the gastroepiploic vessels remained to supply a gastric tube. An end-to-side cervical esophagogastrostomy was performed on the posterior wall of the gastric tube using a circular stapler. The omentoplasty--wrapping the esophagogastrostomy--was performed. A retrosternal route for reconstruction was used in 23 patients and a posterior mediastinal route in 9 patients. RESULTS: Esophageal anastomotic leakage occurred in only 1 patient, 3.1% overall. There was neither pyothorax nor mediastinitis. There was no lethal anastomotic leakage. Later, 2 patients (6.2%) developed an anastomotic stricture that required balloon dilatation. CONCLUSIONS: Omentoplasty to reinforce cervical esophagogastrostomy decreases anastomotic failure following radical esophagectomy with three-field lymph node dissection.     

Extensive hemorrhagic erosive gastritis associated with acute pancreatitis successfully treated with a somatostatin analog

In massive hemorrhage from acute gastric mucosal lesions, it is occasionally difficult to control the bleeding with nonsurgical therapy. We used the somatostatin analog, octreotide, which suppresses gastric and pancreatic function, to treat severe hemorrhagic erosive gastritis in a patient with acute pancreatitis. A 22-year-old man presented with epigastralgia and melena. Blood levels of pancreatitis markers were elevated. Computed tomography revealed diffuse enlargement of the pancreas, without fluid collection around the organ. An endoscopic examination showed extensive hemorrhagic erosions over almost the whole gastric mucosa. We diagnosed extensive hemorrhagic erosive gastritis with acute pancreatitis. A protease inhibitor (nafamostat mesilate 50 mg/day) and an H₂ receptor antagonist (famotidine 40 mg/day) were administered by injection for 6 days; the patient's serum and urine amylase levels fell, but the gastric erosions with hemorrhage were not attenuated. Octreotide was given subcutaneously, at a daily dose of 100 μg for 5 days, without famotidine administration. His melena disappeared, and the gastric erosions were markedly decreased. Administration of the somatostatin analog, octreotide, proved to be effective treatment in a patient with severe hemorrhagic erosive gastritis associated with acute pancreatitis.
