Stasis Gastric Ulcer: A Complication of Duodenal Ulcer

A causal relation between gastric stasis and gastric ulceration is suggested by the literature reviewed. In obstructive duodenal ulcer disease it is important to know that a concomitant gastric ulcer may be present and causing the symptoms. In combined ulcers, symptoms are more severe and treatment is more difficult.A clinical study of 60 cases of stasis gastric ulcer associated with chronic duodenal ulcer disease is presented. Twenty-six of these patients with gastric ulcers were bleeding at the time of their admission. The mortality rate was at least twice that for solitary ulcer. Early warning symptoms of stasis were fatigue, anorexia, fullness and weight loss; vomiting was a late manifestation. X-ray findings were often inaccurate; evidence of retention was reported in only 21. Gastric residue measurements were particularly useful in showing gastric retention.Since the basic disease in combined ulcers is the duodenal lesion, surgical treatment is primarily that for duodenal ulcer.     

Vagotomy and Pyloroplasty for Gastric Ulcer

In a series of 68 patients with gastric ulcer who were treated by vagotomy and pyloroplasty there were no operative deaths, though one patient who received massive transfusions died 14 weeks later from hepatic necrosis probably associated with serum hepatitis. Four patients developed recurrent peptic ulceration requiring further surgical treatment. The clinical condition of all but three of the remainder was satisfactory after an average follow-up period of three years and two months. Of the 14 patients who presented with an acutely bleeding gastric ulcer, one subsequently required gastrectomy for continued bleeding; in all the others the immediate and long-term results were satisfactory. Of 21 patients with a “high” ulcer and 29 with combined gastric and duodenal ulceration one (4·8%) and three (10%) respectively suffered recurrences. We conclude that vagotomy and pyloroplasty is a satisfactory form of treatment for a high or bleeding gastric ulcer, but that for all other gastric ulcers some form of gastric resection is preferable.     

Parathion Poisoning—A New Antidote!

Two thousand five hundred forty-five cases of upper gastrointestinal tract hemorrhage were studied especially with a view to determining the indications for urgent surgical treatment.Decisions as to whether and when to operate were as follows:Immediate operation for patients over 50 years with a good history of ulcer and a severe initial bleed.Operation after the first repetition of bleeding in patients (1) over 50 with a good history and a mild initial bleed, (2) over 50 with inconclusive history but severe initial bleed, (3) under 50 with a good history and a severe initial bleed.In all other cases, operation was used only if conservative treatment failed.Absolute indications for operation were (a) association with perforation, (b) association with stenosis, (c) persistence of severe ulcer pain after hemorrhage, (d) continuous bleeding.Since operation is to be avoided if possible in cases of esophagitis, erosive gastritis and small acute or subacute ulcers, emergency gastroscopy has valuable uses.Where operation is deemed necessary and no obvious lesion found at laparotomy, blind gastrectomy^* appears to be the most satisfactory procedure.The mortality rate associated with upper gastrointestinal tract bleeding in patients less than 60 years of age was low (2.5 per cent). Even in cases in which operation was required, it was 6.2 per cent. Over 60 years the mortality rises steeply with increasing age, and in cases of operation the rise is even steeper.By using the methods of selection the overall mortality rate was appreciably reduced.     

Mortality in patients with haematemesis and melaena: a prospective study.

In a prospective study of death in 817 patients with haematemesis and melaena admitted on 894 occasions, the protocol included admission of all patients to a defined unit, early endoscopy and resuscitation, and planned management. Over the three consecutive two-year periods of the study mortality significantly decreased from 9% to 2.4%. Although the operative rate remained the same, the operative mortality fell from 16% to 1.6%. The fall in mortality was greatest in patients with bleeding gastric ulcers. These results suggest that prospective studies with a defined policy can influence the mortality in patients with upper gastrointestinal bleeding.     

Gastric cancer: a curable disease in Britain.

OBJECTIVE--To determine whether more vigorous efforts aimed at earlier diagnosis allied to radical surgical resection lead to improved survival of patients with gastric cancer. DESIGN--Prospective audit of all cases of gastric cancer treated during 1970-89. SETTING--Department of surgery, general hospital. SUBJECTS--493 consecutive patients with gastric adenocarcinoma. MAIN OUTCOME MEASURES--Operative mortality, postoperative morbidity, and five year survival after radical potentially curative resection. RESULTS--207 (42%) patients underwent potentially curative resection. The proportion of all patients in whom this was possible increased significantly (p < 0.01) from 31% in the first five year period to 53% in the last five year period. The proportion of patients who had early gastric cancer rose from 1% to 15% (p < 0.01) and stage I disease rose from 4% to 26% (p < 0.001). After potentially curative resection, mortality 30 days after operation was 6%. Operative mortality decreased from 9% in the 1970s to 5% in the 1980s. Likewise, the incidence of serious postoperative complications decreased from 33% in the 1970s to 17% in the 1980s (p < 0.01). Five year survival was 60% in patients who underwent curative resection, 98% in patients with early gastric cancer, and 93%, 69%, and 28% in stage I, II, and III disease respectively. By the late 1980s five year survival after operation was about 70%. CONCLUSIONS--These findings suggest that an increasing proportion of patients with gastric cancer could be diagnosed at a relatively early pathological stage when about two thirds are curable by means of radical surgery.     

Comparison of surgical and medical management of bleeding peptic ulcers.

During 1975-80, 908 patients admitted to Nottingham hospitals with gastrointestinal bleeding and found to have gastric or duodenal ulcers were analysed retrospectively for short-term outcome of treatment. Overall one-quarter of all patients underwent operation, but when the years 1975-7 were compared with 1978-80 the operation rate fell from one in three to just over one in five. Death rates were much lower in patients treated medically than in those who underwent operation, and the risks of operation were greater for patients with gastric ulcer. Less conventional operations were attended by greater mortality. Almost all patients who died during medical treatment and three-quarters of those who died after operation were over 65. No differences in age or clear variations in haemoglobin concentrations or transfusion requirements were found between the earlier and later periods. Reduction in operation rates had no appreciable effect on mortality, despite the accepted view that early operation is advisable.     

Stigmata of recent haemorrhage in diagnosis and prognosis of upper gastrointestinal bleeding

In 277 consecutive episodes of suspected upper gastrointestinal bleeding, lesions bearing stigmata of recent haemorrhage (stigmata) were found by endoscopy in 110 (47%) out of 233 patients who were judged to have bled; 78 (33%) had lesions without stigmata, and in 45 (19%) no lesion was seen. Results in 176 entirely unselected admissions for upper gastrointestinal bleeding were similar.Forty-eight chronic duodenal and 41 chronic gastric ulcers were identified by endoscopy. Stigmata were found in 27 (56%) and 33 (80%) of these cases respectively. Sixteen patients had multiple lesions, and in 12 (75%) the presence of stigmata permitted diagnosis of the source of the haemorrhage. Stigmata were more likely to be seen in cases of duodenal ulcer, Mallory-Weiss lesions, and oesophageal varices when endoscopy was performed within 12 hours of bleeding, but were as common in cases of gastric ulcer after longer intervals.In the absence of stigmata one out of 21 patients with duodenal ulcer had further haemorrhage and one other needed emergency surgery; no patient with gastric ulcer had further haemorrhage or needed emergency surgery. In contrast, when stigmata were present 15 of the 27 patients with duodenal ulcer (56%) had further haemorrhage and 17 (63%) needed emergency surgery; of the 33 patients with gastric ulcer, 10 (30%) had further haemorrhage and 15 (45%) required emergency surgery. Superficial mucosal lesions may have been the source of haemorrhage when an ulcer unmarked by stigmata was seen at endoscopy. Stigmata were superior to any other single factor or combination of factors in predicting rebleeding and the need for emergency surgery.     

Systematic review and meta-analysis of proton pump inhibitor therapy in peptic ulcer bleeding

Objectives To review randomised controlled trials of treatment with a proton pump inhibitor in patients with ulcer bleeding and determine the impact on mortality, rebleeding, and surgical intervention.Design Systematic review and meta-analysis.Data sources Cochrane Collaboration''s trials register, Medline, and Embase, handsearched abstracts, and pharmaceutical companies.Review methods Included randomised controlled trials compared proton pump inhibitor with placebo or H₂ receptor antagonist in endoscopically proved bleeding ulcer and reported at least one of mortality, rebleeding, or surgical intervention. Trials were graded for methodological quality. Two assessors independently reviewed each trial, and disagreements were resolved by consensus.Results We included 21 randomised controlled trials comprising 2915 patients. Proton pump inhibitor treatment had no significant effect on mortality (odds ratio 1.11, 95% confidence interval 0.79 to 1.57; number needed to treat (NNT) incalculable) but reduced rebleeding (0.46, 0.33 to 0.64; NNT 12) and surgery (0.59, 0.46 to 0.76; NNT 20). Results were similar when the meta-analysis was restricted to the 10 trials with the highest methodological quality: 0.96, 0.46 to 2.01, for mortality; 0.41, 0.25 to 0.68, NNT 10, for rebleeding; 0.62, 0.46 to 0.83, NNT 25, for surgery.Conclusions Treatment with a proton pump inhibitor reduces the risk of rebleeding and the requirement for surgery after ulcer bleeding but has no benefit on overall mortality.     

Surgical Outcomes and Prognostic Factors of T4 Gastric Cancer Patients without Distant Metastasis

Objective

To evaluate surgical outcomes and prognostic factors for T4 gastric cancer treated with curative resection.

Methods

Between January 1994 and December 2008, 94 patients diagnosed with histological T4 gastric carcinoma and treated with curative resection were recruited. Patient characteristics, surgical complications, survival, and prognostic factors were analyzed.

Results

Postoperative morbidity and mortality were 18.1% and 2.1%, respectively. Multivariate analysis indicated lymph node metastasis (hazard ratio, 2.496; 95% confidence interval, 1.218–5.115; p = 0.012) was independent prognostic factor.

Conclusions

For patients with T4 gastric cancer, lymph node metastasis was associated with poorer survival. Neoadjuvant chemotherapy or aggressive adjuvant chemotherapy after radical resection was strongly recommended for these patients.     

Vagotomy or Gastrectomy for Gastric Ulcer

Patients treated in a randomized controlled comparison of management of benign gastric ulcer of the body of the stomach, comprising 50 patients treated by Billroth I partial gastrectomy and 50 patients treated by vagotomy and pyloroplasty and biopsy of the ulcer, were followed up for about five years (range one and a half to eight and a half years). No statistically significant difference has been found between the functional results (Visick grading) of the two groups. There was no operative mortality. Postoperative morbidity (17 against 5) and length of stay in hospital (14 against 10 days) were significantly greater after gastrectomy. Seven patients after vagotomy have been submitted to gastrectomy (three for recurrent gastric ulceration, three for gastric cancer, and one for bleeding), which is a statistically significant excess compared with no reoperation after gastrectomy. While vagotomy and pyloroplasty can be useful to avoid a technically difficult gastrectomy, it cannot be said to replace partial gastrectomy in the treatment of gastric ulcer.     

Perioperative surgery- and anaesthesia-related risks of laparoscopic Roux-en-Y gastric bypass - a single centre,retrospective data analysis

Background

Conservative obesity treatment often leads to limited results. Bariatric surgery is highly efficient, but the candidates are at risk of developing perioperative complications. Bariatric outcomes have been well described in the past, but there are only few reports of perioperative outcomes.The aim of this study was to evaluate the incidence of anaesthetic and surgical complications of Roux-en-Y bypass.

Methods

Data of all adult patients, who underwent primary Roux-en-Y gastric bypass surgery between 1/2006 and 12/2013 at the University Hospital Zurich were analysed. Using our clinical database, anaesthetic and surgical complications during the first 30?days after surgery were analysed and risk factors determined by multivariate analysis.

Results

Seven hundred eleven patients (72% female, median age 40?years) were analysed. Overall, surgical complications occurred in 34% patient, while complications attributable to anaesthesia occurred in 37%. Post-operative nausea and vomiting (PONV) were observed in 34%, intubation-related complications in 4%, and delayed extubation in 2% of our patients. Within the first 30?days after surgery, 22% of the patients presented with an infection. Gastrointestinal complications were found in 8%, and bleeding complications in 3%. Anaesthesia complications were less common in older patients and in patients anaesthetized with a volatile anaesthetic. Severe complications were more common in patients with a lower body mass index (BMI) and with longer surgery. The risk to develop a postoperative infection was higher in diabetic patients.

Conclusion

Roux-en-Y bariatric surgery has few anaesthetic complications, the most common is PONV. PONV is more common in younger patients and not more common with volatile anaesthetics. Major complications are overall rare and occur in patients with lower BMI and longer surgery, likely reflecting more difficult procedures.

     

Pretreatment Gastric Lavage Reduces Postoperative Bleeding after Endoscopic Submucosal Dissection for Gastric Neoplasms

Aim

For patients receiving endoscopic submucosal dissection (ESD), there is urgent need pertaining to the prevention of postoperative bleeding. We conducted a retrospective propensity score-matched study that evaluated whether pre-ESD gastric lavage prevents postoperative bleeding after ESD for gastric neoplasms.

Methods

From September 2002 to October 2015, the 760 consecutive patients receiving ESD for gastric neoplasm were enrolled and data regarding them were retrospectively analyzed. All patients received conventional preventive treatment against delayed bleeding after ESD, including the administration of proton pump inhibitor and preventive coagulation of visible vessels, at the end of the ESD procedure.

Results

Pre-ESD risk factors for postoperative bleeding included tumor size and no gastric lavage. Using multivariate analysis tumor size >2.0 cm (HR 2.90, 95% CI 1.65–5.10, p = 0.0002) and no gastric lavage (HR 3.20, 95% CI 1.13–9.11, p = 0.029) were found to be independent risk factors. Next, we evaluated the effect of gastric lavage on the prevention of post-ESD bleeding using a propensity score-matching method. A total of 284 subjects (142 per group) were selected. Adjusted odds ratio of gastric lavage for post-ESD bleeding was 0.25 (95% CI 0.071–0.886, p = 0.032).

Conclusion

Pretreatment gastric lavage reduced postoperative bleeding in patients receiving ESD for gastric neoplasm.     

Prognosis following Upper Gastrointestinal Bleeding

Background

Upper gastrointestinal (GI) bleeding is one of the most common, high risk emergency disorders in the western world. Almost nothing has been reported on longer term prognosis following upper GI bleeding. The aim of this study was to establish mortality up to three years following hospital admission with upper GI bleeding and its relationship with aetiology, co-morbidities and socio-demographic factors.

Methods

Systematic record linkage of hospital inpatient and mortality data for 14 212 people in Wales, UK, hospitalised with upper GI bleeding between 1999 and 2004 with three year follow-up to 2007. The main outcome measures were mortality rates, standardised mortality ratios (SMRs) and relative survival.

Results

Mortality at three years was 36.7% overall, based on 5215 fatalities. It was highest for upper GI malignancy (95% died within three years) and varices (52%). Compared with the general population, mortality was increased 27-fold during the first month after admission. It fell to 4.3 by month four, but remained significantly elevated during every month throughout the three years following admission.The most important independent prognostic predictors of mortality at three years were older age (mortality increased 53 fold for people aged 85 years and over compared with those under 40 years); oesophageal and gastric/duodenal malignancy (48 and 32 respectively) and gastric varices aetiologies (2.8) when compared with other bleeds; non-upper GI malignancy, liver disease and renal failure co-morbidities (15, 7.9 and 3.9); social deprivation (29% increase for quintile V vs I); incident bleeds as an inpatient (31% vs admitted with bleeding) and male patients (25% vs female).

Conclusion

Our study shows a high late as well as early mortality for upper GI bleeding, with very poor longer term prognosis following bleeding due to malignancies and varices. Aetiologies with the worst prognosis were often associated with high levels of social deprivation.     

Helicobacter pylori stool antigen test in patients with bleeding peptic ulcers

BACKGROUND: Helicobacter pylori has been linked to chronic gastritis, peptic ulcers, gastric cancer and mucosa-associated lymphoid tissue lymphoma. Invasive tests are less sensitive than noninvasive tests in diagnosing H. pylori infection in patients with bleeding peptic ulcers. The H. pylori stool antigen test has been useful in diagnosing H. pylori in patients with peptic ulcers before and after eradication of H. pylori. The aim of this study was to evaluate the H. pylori stool antigen test in patients with bleeding peptic ulcers. METHODS: Patients with bleeding and nonbleeding peptic ulcers underwent a rapid urease test, histology, bacterial culture and H. pylori stool antigen test. Positive H. pylori infection was defined as a positive culture or both a positive histology and a positive rapid urease test. Helicobacter pylori stool antigen was assessed with a commercial kit (Diagnostec H. pylori antigen EIA Kit, Hong Kong). RESULTS: Between October 2000 and April 2002, 93 patients with bleeding peptic ulcers (men/women: 78/15, gastric ulcer/duodenal ulcer: 58/35) and 59 patients with nonbleeding peptic ulcers (men/women: 47/12, gastric ulcer/duodenal ulcer: 30/29) were enrolled in this study. Forty-seven (50.5%) patients with bleeding peptic ulcers and 30 (50.8%) patients with nonbleeding peptic ulcers, were found to be infected with H. pylori (p > .1). Helicobacter pylori stool antigen tests were positive in 54 (58.1%) and 30 (50.8%) patients with bleeding peptic ulcers and nonbleeding peptic ulcers, respectively (p > .1). The sensitivity (82% vs. 93%), specificity (68% vs. 93%), positive predictive value (74% vs. 93%), negative predictive value (77% vs. 93%) and diagnostic accuracy (75% vs. 93%) were all lower in patients with bleeding vs. nonbleeding peptic ulcers. The specificity, positive predictive value, and diagnostic accuracy of the H. pylori stool antigen test in patients with bleeding peptic ulcers were significantly lower than those in patients with nonbleeding peptic ulcers (p = .01, p = .02 and p = .003, respectively). CONCLUSION: The H. pylori stool antigen test is not reliable for diagnosing H. pylori infection in patients with bleeding peptic ulcers.     

The value of oral contrast ultrasonography in the diagnosis of gastric cancer in elderly patients

Background

This study aims to investigate the value of oral contrast ultrasonography (OCUS) in the diagnosis of gastric cancer in elderly patients.

Methods

OCUS data obtained from patients ≥?60?years old were retrospectively analyzed and compared with gastroscopy results.

Results

Among the 12,716 subjects examined by OCUS, 5021 subjects were ≥?60?years old, which accounted for 39.48% (5021/12,716). Gastritis, gastric polyp, benign ulcer, and gastric cancer were detected by OCUS in 1099 patients. Among them, 196 patients underwent gastroscopy. Furthermore, ulcerative lesions were detected in 32 patients by OCUS and in 51 patients by gastroscopy, and the coincidence rate was 62.74%. Among these patients, gastric cancer was diagnosed in 18 patients by OCUS with a detection rate of 1.64% (18/1099) and detected in 19 patients by gastroscopy with a diagnostic coincidence rate of 94.73% (18/19). Furthermore, benign ulcer was detected in 14 patients by OCUS and in 32 patients by gastroscopy, and the diagnostic coincidence rate was 43.75% (14/32).

Conclusion

OCUS helps to timely detect senile gastric cancer and can be used as a suitable technique for the detection of gastric diseases.

     

MANAGEMENT OF UPPER GASTROINTESTINAL HEMORRHAGE

In the past few years gastric resection has become the therapy of choice for patients with massive hemorrhage from duodenal ulcer. When this is done as an emergency procedure the ability of the surgeon is often taxed to the limit. Although sometimes easy, control is often extraordinarily difficult. Many important technical details must be considered in order to attain a successful outcome. This method of therapy has proved to be very satisfactory with patients who are in good condition for operation, and even in the poorer risks seen on ward service has resulted in a surgical mortality of only 7 per cent in all patients less than 60 years of age treated for this extremely severe type of hemorrhage. In the older age groups mortality rates still remain high.     

The results of Helicobacter pylori eradication on repeated bleeding in patients with stomach ulcer

The triple therapy of Helicobacter pylori eradication prevents repeated bleeding from stomach ulcer. The aim of this one-way blind prospective study was to evaluate the efficiency of the two-week triple therapy for Helicobacter pylori eradication in preventing renewed bleeding in patients with stomach ulcer within one year. This research included 60 hospitalized patients with bleeding stomach ulcer and positive Helicobacter pylori infection, 34 men and 26 women (average age 59.7 years). The patients were given therapeutic scheme of omeprazol--amoxicilin--metrodinazol (OAM) eradication for 14 days. Eradication of H. pylori infection was defined as lack of proof of the infection one month or several months after therapy suspension. By applying triple OAM therapy within two weeks the eradication was successful in 72%. In the group of 17 H. pylori positive patients there were 8 patients (47.6%) with repeated stomach ulcer and 3 patients (18%) with bleeding. Within the group of 43 H. pylori negative patients there were only 2 patients (4.65%) with repeated stomach ulcer and 1 patient (2%) with bleeding, during the observed period of 12 months. This research confirms the hypothesis about the necessity of eradication of Helicobacter pylori infection in patients with bleeding stomach ulcer as prevention of repeated bleeding.     

Gastric Cooling for Massive Upper Gastrointestinal Bleeding

The treatment of massive upper gastrointestinal hemorrhage by gastric hypothermia was studied clinically in 23 patients: five with peptic ulcer, six with multiple gastric erosions, nine with portal hypertension and varices, and three with coagulation defects. Hemorrhage was controlled in 13 of the patients. The high mortality (14 out of 23 patients) was attributed to the severity of the bleeding and to the underlying disease, particularly in patients with liver failure. This form of treatment is a useful method of treating selected patients with upper gastrointestinal hemorrhage.     

Perioperative cardiovascular complications versus perioperative bleeding in consecutive patients with known cardiac disease undergoing non-cardiac surgery. Focus on antithrombotic medication. The PRAGUE-14 registry

Background

Interruption of antithrombotic treatment before surgery may prevent bleeding, but at the price of increasing cardiovascular complications. This prospective study analysed the impact of antithrombotic therapy interruption on outcomes in non-selected surgical patients with known cardiovascular disease (CVD).

Methods

All 1200 consecutive patients (age 74.2 ± 10.2 years) undergoing major non-cardiac surgery (37.4 % acute, 61.4 % elective) during a period of 2.5 years while having at least one CVD were enrolled. Details on medication, bleeding, cardiovascular complications and cause of death were registered.

Results

In-hospital mortality was 3.9 % (versus 0.9 % mortality among 17,740 patients without CVD). Cardiovascular complications occurred in 91 (7.6 %) patients (with 37.4 % case fatality). Perioperative bleeding occurred in 160 (13.3 %) patients and was fatal in 2 (1.2 % case fatality). Multivariate analysis revealed age, preoperative anaemia, history of chronic heart failure, acute surgery and general anaesthesia predictive of cardiovascular complications. For bleeding complications multivariate analysis found warfarin use in the last 3 days, history of hypertension and general anaesthesia as independent predictive factors. Aspirin interruption before surgery was not predictive for either cardiovascular or for bleeding complications.

Conclusions

Perioperative cardiovascular complications in these high-risk elderly all-comer surgical patients with known cardiovascular disease are relatively rare, but once they occur, the case fatality is high. Perioperative bleeding complications are more frequent, but their case fatality is extremely low. Patterns of interruption of chronic aspirin therapy before major non-cardiac surgery are not predictive for perioperative complications (neither cardiovascular, nor bleeding). Simple baseline clinical factors are better predictors of outcomes than antithrombotic drug interruption patterns.     

Lesions Associated with Gastroduodenal Haemorrhage,in Relation to Aspirin Intake

The incidence of aspirin ingestion during the week preceding overt gastroduodenal bleeding was recorded in 582 patients. A positive aspirin history was found in 80% of patients with acute gastric lesions, in 63% of those in whom no lesion was found, in 52% of those with a chronic duodenal ulcer, and in 49% of patients with a chronic gastric ulcer. In a control series of 542 consecutive patients without overt bleeding admitted to the same wards during part of the time of this investigation the aspirin incidence was 32%.The difference in aspirin habits between these two series confirms that aspirin is a factor in precipitating overt haemorrhage in acute and chronic peptic ulcers, and that it is an important cause of bleeding from the stomach or duodenum, or both, in the absence of a chronic peptic ulcer.
