Acute upper gastrointestinal bleeding due to portal hypertension in children: What is the best timing of endoscopy?

OBJECTIVE: To compare initial clinical/laboratory parameters and outcomes of mortality/rebleeding of endoscopy performed <12 h(early UGIE) versus endoscopy performed after 12-24h(late UGIE) of ED admission in children with acute upper gastrointestinal bleeding(AUGIB) due to portal hypertension. METHODS: This is a retrospective cohort study. From January 2010 to July 2017, medical records of all children admitted to a tertiary care hospital with AUGIB due to portal hypertension were reviewed until 60 days after ED admission. RESULTS: A total of 98 ED admissions occurred from 73 patients. Rebleeding was identified in 8/98(8%) episodes, and 9 deaths were observed. UGIE was performed in 92(94%) episodes, and 53(58%) of them occurred within 12 h of ED admission. Episodes with early UGIE and late UGIE were similar in terms of history/complaints/laboratory data at admission, chronic liver disease associated, AUGIB duration, and initial management. No statistically significant associations were found between early UGIE and the outcomes of death/rebleeding and prevalence of endoscopic hemostatic treatment (band ligation or sclerotherapy) compared to late UGIE. In the multivariable logistic regression model, the endoscopic hemostatic treatment showed a negative association with early UGIE(OR=0.33;95%CI=0.1-0.9;p = 0.04). CONCLUSIONS: This study suggests that in pediatric patients with AUGIB and portal hypertension, UGIE may be performed after 12-24 h without harm to the patient, facilitating better initial clinical stabilization/treatment and optimization of resources.

Survival analyses of elderly gastric cancer patients with or without surgery.

PURPOSE: Deciding whether or not surgery should be performed for elderly patients is sometimes difficult. This study examined the prognosis of patients ≥ 80 years old with gastric cancer who underwent surgery or not. METHODS: The medical records of 111 patients who underwent surgery (surgery group) and 35 who received best supportive care (BSC group) were retrospectively reviewed, excluding those with clinical stage IVB disease, those with a performance status of 4, and those who underwent endoscopic submucosal dissection. The overall survival was compared between the two groups. RESULTS: The patients in the BSC group were significantly older and had worse performance status scores, worse physiological scores, and lower prognostic nutritional indexes than those in the surgery group. The patients in the surgery group showed a significantly better survival than those in the BSC group (median survival time, 38.9 vs. 11.4 months; p = 0.01) even after propensity score matching. In the subgroups of patients ≥ 90 years old and those with a performance status of 3, no marked difference in the survival between the 2 groups was observed. CONCLUSIONS: Surgery imbued a survival benefit to elderly gastric cancer patients, except for those ≥ 90 years old and those with a performance status of ≥ 3. The surgical indication of patients ≥ 90 years old and those with a performance status of ≥ 3 requires careful deliberation.

Utility of Endoscopy in Hospitalized Patients with Gastrointestinal Hemorrhage and Pulmonary Hypertension.

BACKGROUND: Gastrointestinal hemorrhage (GIH) has been reported as one of the most common GI complications in patients with pulmonary hypertension (PH). There is paucity of data on the national burden of GIH in patients with PH. We aimed to assess the prevalence, trends and outcomes of endoscopic interventions in patients with PH who were admitted with GIH. METHOD: We queried National Inpatient Sample (NIS) database from 2005 to 2014 and identified the patients hospitalized with primary or secondary discharge diagnosis of PH (ICD 9 CM Code: 416.0, 416.8, and 416.9). Using Clinical Classification Software Coding system (153) patients with concurrent diagnosis of GIH were then identified. We studied the prevalence and trends of GIH in PH, factors associated with GIH, use of endoscopy, factors associated with utilization of endoscopic interventions, endoscopy outcomes including mortality, and overall healthcare burden. RESULTS: Out of 7,586,973 PH hospitalizations 3.2% (N = 246,358) had concurrent GIH, with a rising prevalence of GIH in PH patients during the last decade. Clinical predictors for GIH in PH included older age, congestive heart failure, anticoagulation therapy and concurrent alcohol abuse. Mean length of stay (LOS) in PH patients hospitalized with GIH was significantly higher than without GIH (8.6 vs. 6.4 days, p < 0.01) along with a significant increase in hospitalization cost ($20,189 vs. $14,807, p < 0.01). Similarly, odds of in-hospital mortality increase by ~ 1.5 times in PH patients with GIH than those without it (adjusted odds ratio [aOR: 1.45, 95%CI: 1.43-1.47]). Endoscopic interventions were performed in 48.6% of patients with PH and GIH during their hospitalization. Older patients were more likely to undergo endoscopy, as well as the patients who received blood transfusion, and those with hypovolemic shock. Patients with acute respiratory failure and acute renal failure were less likely to get endoscopy. Mean LOS in patients undergoing endoscopic intervention was significantly higher than those who did not receive any intervention (8.7 vs. 8.4 days, p < 0.01), without a substantial increase in hospitalization cost ($20,344 vs. $20,041, p < 0.01). Also, there was a significant decrease in in-hospital mortality in patients undergoing endoscopic interventions. CONCLUSION: Concurrent GIH in patients with PH increases length of stay; healthcare costs and increases in-hospital mortality. Use of endoscopic interventions in these patients is associated with reduced length of stay, in-hospital mortality without significantly increasing the overall health care burden and should be considered in hospitalized patients with PH who are admitted with GIH. Future studies comparing GIH patients with and without PH should be done to assess if PH is a risk factor for worse outcomes. CLINICAL TRIAL REGISTRATION NUMBER: No IRB required due to use of national de-identified data.

Postoperative morbidity and mortality after mesorectal excision with laparoscopic versus conventional open lateral lymph node dissection for advanced rectal cancer: A meta-analysis.

Lateral lymph node dissection (LLND) is a challenging procedure due to its technical difficulty and higher incidence of surgical morbidity, thus the purpose of this study is to compare the postoperative morbidity and mortality between laparoscopic and conventional open LLND after mesorectal excision (ME) for advanced rectal cancer. A comprehensive search was conducted in August 2019 based on data from PubMed, Embase, Cochrane Library, CNKI and Wanfang Data to identify relevant studies, and studies comparing laparoscopic with conventional open LLND were included. Seven studies with 335 cases in the laparoscopic LLND group and 841 cases in the conventional open LLND group were finally included. Compared with the conventional open LLND group, the laparoscopic LLND group enjoys a lower postoperative morbidity (OR = 0.47,95% CI [0.23, 0.97], P = 0.04), same postoperative mortality (Postoperative mortality in both groups was zero), shorter length of postoperative hospitalization (WMD = -5.30, 95% CI [-8.42, -2.18], P = 0.0009), less wound infection (OR = 0.40,95% CI [0.21, 0.77], P = 0.006), less intestinal obstruction (OR = 0.50,95% CI [0.29, 0.84], P = 0.009), and less urinary retention (OR = 0.61,95% CI [0.38, 0.97], P = 0.04). There were no significant differences in the incidence of anastomotic leakage, abdominal pelvic abscess and urinary tract infection between the two groups (P > 0.05). But in the sensitivity analysis, there was a significant change of urinary tract infection (OR = 0.22, 95%CI [0.06, 0.89], P = 0.03), and the degree of between-study heterogeneity decreased greatly. In conclusion, laparoscopic LLND may be a better alternative to conventional open LLND for advanced rectal cancer with lower postoperative morbidity and shorter postoperative hospital stay.

Predictors of endoscopic intervention in upper gastrointestinal bleeding patients hospitalized for another illness: a multi-center retrospective study.

BACKGROUND: To characterize variables that may predict the need for endoscopic intervention in inpatients admitted for several causes who during the hospitalization developed acute non-variceal upper gastrointestinal bleeding (NVUGIB). METHODS: A retrospective analysis of inpatients who underwent upper gastro-intestinal endoscopy for acute NVUGIB while hospitalized for other causes from 1 January 2016 to 1 December 2017, was performed. In the primary outcome analysis, patients (N.=14) who underwent endoscopic intervention (group A) were compared to those (N.=87) who did not need for endoscopic intervention (group B). Secondary outcome analysis included patients who had significant endoscopic findings compared to those who did not have them. RESULTS: Multivariate regression analysis showed that in the primary outcome analysis, two parameters were significant: the number of packed red blood cells (PRBC) units transfused (odds ratio [OR]: 1.5, P=0.01) and Rockall Score (RS) (OR: 1.4, P=0.06) with receiver operator characteristic (ROC) curve of 0.7844. In the secondary outcome analysis, only the use of proton pump inhibitor drugs at admission was associated with protective effect for the development of significant endoscopic findings (odds ratio [OR]: 0.42, P=0.05) with ROC curve of 0.7342. CONCLUSIONS: In hospitalized patients, in case of de novo NVUGIB, the number of PRBC units transfused and RS are predictive of significant endoscopic findings.

Open colectomy vs. laparoscopic colectomy in Japan: a retrospective study using real-world data from the diagnosis procedure combination database.

PURPOSE: To compare the short-term outcomes of conventional open colectomy with those of laparoscopic colectomy for colon cancer. METHODS: We retrieved data between January 2014 and March 2016 from the Diagnosis Procedure Combination database. A total of 69,418 patients who underwent colectomy for colon cancer were analyzed from among 15,901,766 cases of colorectal cancer. We applied a multilevel logistic regression model using a 2-level structure of individuals nested from 1065 hospitals. RESULTS: A total of 22,440 open colectomy and 46,978 laparoscopic colectomy procedures were performed. The in-hospital mortality rate was significantly lower in the laparoscopic group than in the open group (0.28% vs. 0.06%, odds ratio [OR] 0.40, p < 0.001). Similarly, the 30-day postoperative mortality rate (0.14% vs. 0.03%, OR 0.47, p = 0.019) and surgical morbidity rate (43.0% vs. 25.3%, OR 0.47, p < 0.001) were significantly lower in the laparoscopic group than in the open group. The postoperative length of stay was significantly longer in the open group (mean difference - 5.6 days, p < 0.001) than in the open group. The admission cost was significantly greater in the open group than in the laparoscopic group (mean difference - 95,080 yen, p < 0.001). CONCLUSIONS: Laparoscopic colectomy is safe and effective in the short term.

The use of emergency laparoscopy for acute abdomen in the elderly: the FRAILESEL Italian Multicenter Prospective Cohort Study.

As the world population is aging rapidly, emergency abdominal surgery for acute abdomen in the elderly represents a global issue, both in developed and developing countries. Data regarding all the elderly patients who underwent emergency abdominal surgery from January 2017 to December 2017 at 36 Italian surgical departments were analyzed with the aim to appraise the contemporary reality regarding the use of emergency laparoscopy for acute abdomen in the elderly. 1993 patients were enrolled. 1369 (68.7%) patients were operated with an open technique; whereas, 624 (31.3%) underwent a laparoscopic operation. The postoperative morbidity rate was 32.6%, with a statically significant difference between the open and the laparoscopic groups (36.2% versus 22.1%, p < 0.001). The reported mortality rate was 8.8%, with a statistically significant difference between the open and the laparoscopic groups (11.2% versus 2.2%, p < 0.001). Our results demonstrated that patients in the ASA II (58.1%), ASA III (68.7%) and ASA IV (88.5%) groups were operated with the traditional open technique in most of the cases. Only a small percentage of patients underwent laparoscopy for perforated gastro-duodenal ulcer repair (18.9%), adhesiolyses with/without small bowel resection (12.2%), and large bowel resection (10.7%). Conversion to open technique was associated with a higher mortality rate (11.1% versus 2.2%, p < 0.001) and overall morbidity (38.9% versus 22.1%, p = 0.001) compared with patients who did not undergo conversion. High creatinine (p < 0.001) and glycaemia (p = 0.006) levels, low hemoglobin levels (p < 0.001), oral anticoagulation therapy (p = 0.001), acute respiratory failure (p < 0.001), presence of malignancy (p = 0.001), SIRS (p < 0.001) and open surgical approach (p < 0.001) were associated with an increased risk of postoperative morbidity. Regardless of technical progress, elderly patients undergoing emergency surgery are at very high risk for in-hospital complications. A detailed analysis of complications and mortality in the present study showed that almost 9% of elderly patients died after surgery for acute abdomen, and over 32% developed complications.

Tracheostomies and PEGs: When Are They Really Indicated?

Surgeons are often asked to perform tracheostomies and percutaneous endoscopic gastrostomies for a wide variety of patients. As consultants, surgeons are tasked with honoring the relationship between the referring provider and the patient while also assessing whether the consult is appropriate given the patient's prognosis and goals of care. This article discusses the most common conditions for which these procedures are requested and reviews the evidence supporting either the placement or avoidance of these tubes in each condition. It provides a framework for surgeons to use when discussing these procedures in the context of goals of care.

Impact of the protocol proposed by the American Society for Gastrointestinal Endoscopy in patients at high risk of choledocholithiasis, in Puebla Regional Hospital ISSSTE in Mexico.

BACKGROUND: Choledocholithiasis is one of the main complications of cholelithiasis with a prevalence in the Mexican population of 14%. The management through the guide proposed by the American Society for Gastrointestinal Endoscopy (ASGE) in 2010 can support the surgeon for the timely resolution of the pathology. OBJECTIVE: To determine that the guide proposed by ASGE for the management of choledocholithiasis in patients with "high risk" reduces the complications of this pathology. METHODS: A comparative, retrospective case-control study was conducted from January 1, 2015 to December 31, 2017. We included patients who were stratified at high risk of choledocholithiasis according to the ASGE guidelines. They were divided into 2 groups: the case group (diagnosis by ASGE guidelines) was submitted directly to endoscopic retrograde cholangiopancreatography (ERCP), the second group (no ASGE) followed the protocol of performing computed tomography, magnetic cholangioresonance, and finally ERCP. RESULTS: Of 61 patients with choledocholithiasis, the following groups were compared: the appearance of cholangitis, the complications after ERCP, time of ERCP, days of hospital stay and mortality. Obtaining significant difference in: "complications post ERCP" group ASGE 3/35 (9%), group no ASGE 8/26 (30.7%) with OR of 0.2 (0.05 - 0.9 IC 95%) and a p = 0.03; "Cholangitis" group ASGE 2/35 (5.7%), group no ASGE 8/26 (30-7%) with ORP 0.13 (0.03-0.71 IC 95%) and p = 0.009. CONCLUSION: In our setting, the use of the ASGE guideline reduces the presence of cholangitis and post-ERCP complications.

ANTECEDENTES: La coledocolitiasis es una de las principales complicaciones de la colelitiasis, con una prevalencia en la población mexicana del 14%. El manejo a través de la guía propuesta por la American Society for Gastrointestinal Endoscopy (ASGE) en 2010 puede apoyar al cirujano para la resolución oportuna de la patología. OBJETIVO: Determinar que el uso de la guía de la ASGE para el manejo de coledocolitiasis en pacientes con «alto riesgo¼ reduce las complicaciones de esta patología. MÉTODO: Estudio comparativo, retrospectivo, de casos y controles, del 1 de enero de 2015 al 31 de diciembre de 2017. Se incluyeron pacientes que se estratificaron en alto riesgo de coledocolitiasis de acuerdo con la guía ASGE y se dividieron en dos grupos: el grupo de casos (diagnóstico por guía ASGE) fue sometido directamente a colangiopancreatografía retrógrada endoscópica (CPRE), y el otro grupo (no ASGE) siguió el protocolo de realizar tomografía computarizada, colangiorresonancia magnética y finalmente CPRE. RESULTADOS: De 61 pacientes con coledocolitiasis, se comparó entre los grupos la aparición de colangitis, las complicaciones posteriores a la CPRE, el tiempo de realización de la CPRE, los días de estancia hospitalaria y la mortalidad. Se obtuvo diferencia significativa en complicaciones tras la CPRE (grupo ASGE 3/35 [9%], grupo no ASGE 8/26 [30.7%]; odds ratio [OR]: 0.2; intervalo de confianza del 95% [IC 95%]: 0.05-0.9; p = 0.03) y en colangitis (grupo ASGE 2/35 [5.7%], grupo no ASGE 8/26 [30-7%]; OR: 0.13; IC 95%: 0.03-0.71; p = 0.009). CONCLUSIÓN: En nuestro medio, el empleo de la guía ASGE reduce la presencia de colangitis y las complicaciones tras la CPRE.

Nutritional profile and mortality in patients undergoing percutaneous endoscopic gastrostomy.

INTRODUCTION: Background: malnutrition is a common problem in hospitalized patients, being associated with increased morbidity, mortality and costs. Multiple factors contribute to a deficient nutritional status, making malnutrition the cause or consequence of severe diseases. Percutaneous endoscopic gastrostomy (PEG) is a minimally invasive procedure indicated for long-term administration of enteral nutrition in patients with limited ability for oral intake who have an intact, functional gastrointestinal tract. The aim of this study was to determine the profile of patients undergoing PEG in a tertiary hospital in southern Brazil. Methods: single-center retrospective study of all patients who underwent PEG from January 1st to December 31st, 2016, in a private tertiary hospital located in southern Brazil. Data were collected retrospectively from the patients' medical records, including nutritional status, indications, complications and outcomes. Results: one hundred and thirty-three patients underwent PEG at our institution and were eligible for inclusion in the study. Median patient age was 82 years, and 57.9% were females. The main indication for PEG was dementia syndrome, followed by stroke. As much as 68.4% were diagnosed as severely malnourished and 23.0% had procedure-related complications. Conclusions: PEG tubes are being increasingly used for enteral nutrition in patients with dysphagia or inability to maintain adequate nutritional intake. The findings of the present study highlight the importance of regular nutritional risk screening by a multidisciplinary team, paying special attention to the patient's nutritional status and conditions that may place the patient at risk of developing dysphagia, with the implementation of measures to minimize malnutrition in hospitalized patients.

INTRODUCCIÓN: Introducción: la desnutrición es común en pacientes hospitalizados y se está convirtiendo en causa o consecuencia de enfermedades graves, asociándose a morbilidad, mortalidad y costos aumentados. Múltiples factores contribuyen a un estado nutricional deficiente. La gastrostomía endoscópica percutánea (PEG) es un procedimiento mínimamente invasivo para la administración de nutrición enteral en pacientes con capacidad limitada de ingesta oral que tengan el tracto gastrointestinal intacto y funcional. El objetivo de este estudio fue determinar el perfil de pacientes sometidos a PEG en un hospital terciario del sur de Brasil. Métodos: estudio retrospectivo unicéntrico de todos los pacientes sometidos a PEG del 1 de enero al 31 de diciembre de 2016 en un hospital terciario privado del sur de Brasil. Se recolectaron los datos retrospectivamente en los registros médicos, incluyendo estado nutricional, indicaciones, complicaciones y evolución. Resultados: ciento treinta y tres pacientes se sometieron a PEG en nuestra institución y fueron elegibles para el estudio. La edad mediana fue de 82 años y el 57,9% eran mujeres. Las principales indicaciones para PEG fueron demencia y accidente cerebrovascular. El 68,4% fueron diagnosticados con desnutrición grave y el 23,0% presentaron complicaciones relacionadas al procedimiento. Conclusiones: se utilizan cada vez más tubos de PEG para nutrición enteral en pacientes disfágicos o incapaces de mantener una ingesta nutricional adecuada. Nuestros hallazgos señalan la importancia del cribado para riesgo nutricional por un equipo multidisciplinario, con atención especial al estado nutricional del paciente y a condiciones que pueden ponerlo en riesgo para disfagia y la implementación de medidas para minimizar la desnutrición.

Laparoscopic versus open colectomy: the impact of frailty on outcomes.

Frailty in the elderly population is an important predictor of surgical outcomes. It has been quantified by several models, including the modified frailty index, which has demonstrated applicability in many surgical subspecialties. We aim to conduct the first decade-long retrospective analysis of frailty and complications between open and laparoscopic colectomy. We used the American College of Surgeons National Surgical Quality Improvement Program database to identify colectomies performed between 2005 and 2014. Our primary outcome was 30-day mortality. Secondary outcomes were grouped into five categories: wound, hematologic, pulmonary, renal, or cardiac/vascular complications. Chi-square and multivariate logistic regression were used to identify significant predictors of outcomes. Of the 244,639 colectomies identified in our data set, 117,064 cases were included after exclusion criteria were applied. 42,192 (36%) cases were laparoscopic. Mortality rates among open colectomies in mFI cohorts 0, 1, 2, 3, and ≥ 4 were 1.2, 3.4, 7.9, 14.3, and 20.3%, respectively, while rates in laparoscopic colectomies 0.2, 0.7, 2, 3.5, and 5.4%, respectively (p < 0.05). Logistic regression showed increase likelihood of mortality with open colectomies in all mFI cohorts (p < 0.05). The open approach also had statistically significant higher rates of secondary outcomes in nearly all frailty levels. Our study analyzed the relationship of frailty, approach to colectomy, and postoperative complications. Laparoscopic colectomies resulted in lower mortality rates as well as less wound, hematologic, pulmonary, renal, and cardiovascular complications.

Acute sedation-associated complications in GI endoscopy (ProSed 2 Study): results from the prospective multicentre electronic registry of sedation-associated complications.

OBJECTIVES: Sedation has been established for GI endoscopic procedures in most countries, but it is also associated with an added risk of complications. Reported complication rates are variable due to different study methodologies and often limited sample size. DESIGNS: Acute sedation-associated complications were prospectively recorded in an electronic endoscopy documentation in 39 study centres between December 2011 and August 2014 (median inclusion period 24 months). The sedation regimen was decided by each study centre. RESULTS: A total of 368 206 endoscopies was recorded; 11% without sedation. Propofol was the dominant drug used (62% only, 22.5% in combination with midazolam). Of the sedated patients, 38 (0.01%) suffered a major complication, and overall mortality was 0.005% (n=15); minor complications occurred in 0.3%. Multivariate analysis showed the following independent risk factors for all complications: American Society of Anesthesiologists class >2 (OR 2.29) and type and duration of endoscopy. Of the sedation regimens, propofol monosedation had the lowest rate (OR 0.75) compared with midazolam (reference) and combinations (OR 1.0-1.5). Compared with primary care hospitals, tertiary referral centres had higher complication rates (OR 1.61). Notably, compared with sedation by a two-person endoscopy team (endoscopist/assistant; 53.5% of all procedures), adding another person for sedation (nurse, physician) was associated with higher complication rates (ORs 1.40-4.46), probably due to higher complexity of procedures not evident in the multivariate analysis. CONCLUSIONS: This large multicentre registry study confirmed that severe acute sedation-related complications are rare during GI endoscopy with a very low mortality. The data are useful for planning risk factor-adapted sedation management to further prevent sedation-associated complications in selected patients. TRIAL REGISTRATION NUMBER: DRKS00007768; Pre-results.

Percutaneous endoscopic gastrostomy in older patients with and without dementia: Survival and ethical considerations.

BACKGROUND AND AIM: Notwithstanding multiple recommendations in guidelines, percutaneous endoscopic gastrostomy (PEG)-tube placement is still performed in patients with dementia. In this study, we aim to investigate survival in patients with and without dementia after PEG-tube placement. METHODS: We conducted a retrospective multicenter study in four different hospitals in the Netherlands. Furthermore, we explored the ethical considerations that may play a role in the decision whether or not to insert a PEG tube in a patient with dementia. RESULTS: Three-hundred-and-three patients were included, mean age of 77.4 years. Forty-two (13.9%) patients had dementia. Short-term complications did not differ between patients with and without cognitive disorders (P 0.224). However, patients with dementia survived significantly shorter after PEG placement than did patients without dementia. Adjusted for age and sex, patients with dementia had a 49% increased risk of mortality (hazard ratio 1.49, 95% confidence interval 1.01-2.19). In our exploratory literature search, we found that several ethical concerns and considerations play a role in the decision process of PEG placement. These considerations are both medical and nonmedical and include beliefs regarding the benefits of a PEG tube, a lack of knowledge about the natural course of dementia in both professionals and family of patients, and a fear of letting a patient die hungry. CONCLUSIONS: Patients with dementia had higher mortality rates after PEG placement than patients without dementia. Although multiple ethical concerns and considerations play a role, insertion of a PEG tube in patients with dementia is not appropriate.

Endoscopy Is Relatively Safe in Patients with Acute Ischemic Stroke and Gastrointestinal Hemorrhage.

BACKGROUND: Gastrointestinal hemorrhage (GIH) is reported to occur in 1-8% of patients admitted with acute ischemic stroke (AIS). AIS is considered to be a relative contraindication to GIE. AIMS: Evaluate the outcomes of gastrointestinal endoscopy (GIE) in patients hospitalized with AIS and GIH. METHODS: Patients hospitalized with AIS and GIH were included from the National Inpatient Sample 2005-2014. Primary outcome measure was in-hospital mortality in patients with AIS and GIH who underwent gastrointestinal endoscopy. Secondary outcomes were (1) resource utilization as measured by length of stay (LOS) and total hospitalization costs and (2) to identify independent predictors of undergoing GIE in patients with AIS and GIH. Confounders were adjusted for by using multivariable regression analysis. RESULTS: A total of 75,756 hospitalizations were included in the analysis. Using a multivariate analysis, the in-hospital mortality was significantly lower in patients who underwent GIE as compared to those who did not [aOR: 0.4, P < 0.001]. Patients who underwent GIE also had significantly shorter adjusted mean LOS [adjusted mean difference in LOS: 0.587 days, P < 0.001]. Patients with AIS and GIH who did not undergo GIE had significantly higher adjusted total hospitalization costs. [Mean adjusted difference in total hospitalization costs was $5801 (P < 0.001).] Independent predictors of undergoing GIE in this population were male gender, age > 65 years, Asian or Pacific race, hypovolemic shock, need for blood transfusion and admission to urban non-teaching hospital. CONCLUSIONS: Gastrointestinal endoscopy can be safely performed in a substantial number of patients with AIS and GIH.

Comparison of treatment outcomes between laparoscopic and endoscopic surgeries for relatively small gastric gastrointestinal stromal tumors.

BACKGROUND: Complete surgical resection remains the predominant treatment modality for primary gastrointestinal stromal tumors (GISTs). No therapeutic consensus exists for 2-5 cm gastric GISTs. We compared the efficacy, safety, and prognosis of laparoscopic and endoscopic surgeries in the treatment of relatively small (2-5 cm) intraluminal gastric GISTs. METHODS: We collected 101 patients with relatively small intraluminal gastric GISTs who had integrated clinicopathological data and underwent laparoscopic or endoscopic resection (laparoscopic group n = 66; endoscopic group n = 35). Clinicopathological characteristics, perioperative data, and long-term oncological outcomes were retrospectively analyzed. Comparative analysis of clinicopathological data in the two groups was performed by using a chi-square test, Fisher's exact test, and Student's t-test. Recurrence-free survival (RFS) was analyzed by the log-rank test. RESULTS: All clinicopathological characteristics had no significant difference between the two groups. Patients in the endoscopic group had shorter operation time (P < 0.001), postoperative hospital stay (P < 0.001), time to a liquid diet (P < 0.01), and time to a semi-liquid diet (P < 0.01), and lower hospital charges (P < 0.001), compared to those in the laparoscopic group. Four patients (6.1%) in the laparoscopic group and one patient (2.9%) in the endoscopic group had perioperative complications, but with no significant difference. Recurrence occurred in 6 patients (9.1%) and 2 patients (5.7%) in the laparoscopic and endoscopic groups, respectively. There was no significant difference in RFS between the two groups. CONCLUSION: Endoscopic resection is a feasible and safe treatment modality for patients with relatively small (2-5 cm) intraluminal gastric GISTs. Due to faster recovery and lower cost, endoscopic resection is more suitable for elderly and weak patients, or patients with a poor financial situation.

There Is No Excuse for Mortality Due to Lack of Competency and Training of Paediatric Endoscopists in Gastrointestinal Bleeding Therapy in 2018.

Acute upper gastrointestinal bleeding in children is possibly the last medical emergency which continues to lead to the death of a child due to the lack of competency/clinical judgement of the doctor, as opposed to the disease itself, leading to mortality despite optimum medical intervention. This is unacceptable in any circumstances in 2018. It occurs due to a number of conspiring factors including lack of appreciation of the clinical presentation requiring urgent endoscopic intervention; misapprehension of the urgency of timing required of such an intervention predicated on the severity of the gastrointestinal (GI) bleed; lack of application of a paediatric-specific validated score predicting for such endoscopic intervention; lack of skill in endo-haemostatic intervention techniques by paediatric endoscopists; poor training in such techniques among paediatric endoscopists; paucity of cases with lack of exposure of the paediatric endoscopist regularly to enable skills to be maintained, once acquired; reluctance of adult endoscopists in many centres to support paediatric GI bleeding services. In essence then the paediatric GI community urgently needs to identify centres of excellence to whom these children should be transferred. Transfer is safe in all but the most critical cases once stabilised with transfusion, octreotide/terlipressin and iv proton pump inhibitors. The resources are country-dependent but this is really no excuse. We must not let this parlous state of affairs continue. Solutions are explored in this article and please let this serve as a call to action for all those involved in this continuing debacle in order to save "save-able" lives.

Factors Associated with Rebleeding in Patients with Peptic Ulcer Bleeding: Analysis of the Korean Peptic Ulcer Bleeding (K-PUB) Study.

BACKGROUND/AIMS: Rebleeding is associated with mortality in patients with peptic ulcer bleeding (PUB), and risk stratification is important for the management of these patients. The purpose of our study was to examine the risk factors associated with rebleeding in patients with PUB. METHODS: The Korean Peptic Ulcer Bleeding registry is a large prospectively collected database of patients with PUB who were hospitalized between 2014 and 2015 at 28 medical centers in Korea. We examined the basic characteristics and clinical outcomes of patients in this registry. Univariate and multivariate analyses were performed to identify the factors associated with rebleeding. RESULTS: In total, 904 patients with PUB were registered, and 897 patients were analyzed. Rebleeding occurred in 7.1% of the patients (64), and the 30-day mortality was 1.0% (nine patients). According to the multivariate analysis, the risk factors for rebleeding were the presence of co-morbidities, use of multiple drugs, albumin levels, and hematemesis/hematochezia as initial presentations. CONCLUSIONS: The presence of co-morbidities, use of multiple drugs, albumin levels, and initial presentations with hematemesis/hematochezia can be indicators of rebleeding in patients with PUB. The wide use of proton pump inhibitors and prompt endoscopic interventions may explain the low incidence of rebleeding and low mortality rates in Korea.

Transjugular intrahepatic portosystemic shunt placement before abdominal intervention in cirrhotic patients with portal hypertension: lessons from a pilot study.

BACKGROUND: Abdominal interventions are usually contraindicated in patients with cirrhosis and portal hypertension because of increased morbidity and mortality. Decreasing portal pressure with transjugular intrahepatic portosystemic shunt (TIPS) may improve patient outcomes. We report our experience with patients treated by neoadjuvant TIPS to identify those who would most benefit from this two-step procedure. PATIENTS AND METHODS: All patients treated by dedicated neoadjuvant TIPS between 2005 and March 2013 in two tertiary referral hospitals were included. The primary endpoint was the rate of failure, defined by the inability to proceed to the planned intervention after TIPS placement or persistent liver decompensation 3 months after intervention. The secondary endpoints were the rate of complications, parameters associated with failure, and 1-year survival. RESULTS: Twenty-eight consecutive patients were included, with a mean age of 61.2±6.6 years, mean Child-Pugh score of 6.6±1.5, and mean model for end-stage liver disease score of 10.4±3.3. Procedures were digestive (43%) or liver (25%) resections, abdominal wall surgery (21%), or interventional gastrointestinal endoscopies (11%). The scheduled procedure was performed in 24 (86%) patients within a median of 25 days after TIPS. Procedure failures occurred in six (21%) patients: four did not undergo surgery and two experienced persistent liver decompensation. Seven (25%) patients had postoperative complications, mainly local. Viral origin of cirrhosis, history of encephalopathy, and hepatic surgery were found to be associated with failure. One-year survival in the whole cohort was 70%. CONCLUSION: In selected patients, extrahepatic surgery or interventional endoscopies can be safely performed after portal hypertension has been controlled by TIPS.

Endoscopic Cyanoacrylate Injection with Post-injection Audible Doppler Assessment of Gastric Varices: A Single-Institution Experience.

BACKGROUND AND AIMS: Gastric varices (GV) have higher rates of morbidity and mortality from hemorrhage than esophageal varices. Several studies have shown the safety and efficacy of cyanoacrylate (CA) injection for acute gastric variceal hemorrhage. We report data from our experience with CA injection for GV before and after routine use of post-injection audible Doppler assessment (ADA) for GV obturation and describe long-term outcomes after this therapy. METHODS: We retrospectively identified patients who had documented GV, underwent CA injection, and had at least 2 weeks of follow-up. We recorded and analyzed the survival and rebleeding rates with patient demographics, clinical data, and endoscopy findings between two groups of patients who were categorized by CA injection prior to and after inception of the ADA technique. RESULTS: Seventy-one patients were identified with 16 patients analyzed in a group where ADA was not used (Pre-ADA) and 55 analyzed where ADA was used (Post-ADA). No rebleeding events were observed within 1 week of initial CA injection. No embolic events were reported after any initial CA injection within 4 weeks. The rate of bleed-free survival at 1 year was 69.6% in the Pre-ADA group and 85.8% in the Post-ADA without statistical significance. The all-cause 1-year mortality was 13.8% in the Pre-ADA group and 10.7% in the Post-ADA group without statistical significance. CONCLUSIONS: ADA of CA-injected GV does not appear to significantly affect adverse events or clinical outcomes; however, our findings are limited by small sample size and cohort proportions allowing for significant type II statistical error. Further prospective investigation is required to determine the impact of ADA on clinical outcomes after GV obturation.

Endoscopic variceal ligation combined with argon plasma coagulation versus ligation alone for the secondary prophylaxis of variceal bleeding: a systematic review and meta-analysis.

Endoscopic variceal ligation (EVL) is often recommended as an effective method for the treatment of esophageal varices, despite the important tendency of variceal recurrence. Recent studies indicate that combining EVL with argon plasma coagulation (APC) may be a more effective therapy than ligation alone. To investigate these findings, we carried out a systematic review and meta-analysis to compare the safety and efficacy of EVL combined with APC versus ligation alone for the secondary prophylaxis of esophageal variceal hemorrhage. All studies were searched through PubMed, the Cochrane Library, and Science Direct. The outcome measures were relative risk (RR) or risk difference with 95% confidence intervals (CIs) for dichotomous data and standardized mean difference for continuous data. Heterogeneity was calculated using the χ and the I-tests. Two investigators independently identified four randomized-controlled trials included in the research. The variceal recurrence rate was significantly lower in the combined therapy group (RR=0.19, 95% CI: 0.09-0.41, P=0.000). The bleeding recurrence and mortalities in the two groups showed no significant differences (RR=0.29, 95% CI: 0.08-1.04, P=0.058; risk difference=-0.02, 95% CI: -0.08-0.04, P=0.576, respectively). Although the pyrexia incidence rate was significantly higher in the combined group (RR=3.42, 95% CI: 1.56-7.48, P=0.002), there was intertrial heterogeneity (I=52.5%, P=0.097). EVL combined with APC is superior to ligation alone for endoscopic variceal recurrence without severe adverse events in secondary prophylaxis against esophageal variceal bleeding. More high-quality studies are needed to strengthen this conclusion.
