Preoperative Blood Transfusion Requirements for Hemorrhoidal Severe Anemia: A Retrospective Study of 128 Patients.

BACKGROUND Severe anemia caused by hemorrhoidal hematochezia is typically treated preoperatively with reference to severe anemia treatment strategies from other etiologies. This retrospective cohort study included 128 patients with hemorrhoidal severe anemia admitted to 3 hospitals from September 1, 2018, to August 1, 2023, and aimed to evaluate preoperative blood transfusion requirements. MATERIAL AND METHODS Of 5120 patients with hemorrhoids, 128 (2.25%; male/female: 72/56) experienced hemorrhoidal severe anemia, transfusion, and Milligan-Morgan surgery. Patients were categorized into 2 groups based on their preoperative hemoglobin (PHB) levels after transfusion: PHB ≥70 g/L as the liberal-transfusion group (LG), and PHB <70 as the restrictive-threshold group (RG). The general condition, bleeding duration, hemoglobin level on admission, transfusion volume, length of stay, immune transfusion reaction, surgical duration, and hospitalization cost were compared between the 2 groups. RESULTS Patients with severe anemia (age: 41.07±14.76) tended to be younger than those with common hemorrhoids (age: 49.431±15.59 years). The LG had a significantly higher transfusion volume (4.77±2.22 units), frequency of immune transfusion reactions (1.22±0.58), and hospitalization costs (16.69±3.31 thousand yuan) than the RG, which had a transfusion volume of 3.77±2.09 units, frequency of immune transfusion reactions of 0.44±0.51, and hospitalization costs of 15.00±3.06 thousand yuan. Surgical duration in the LG (25.69±14.71 min) was significantly lower than that of the RG (35.24±18.72 min). CONCLUSIONS Patients with hemorrhoids with severe anemia might require a lower preoperative transfusion threshold than the currently recognized threshold, with an undifferentiated treatment effect and additional benefits.

Over-the-scope clip as a rescue treatment for massive bleeding due to Dieulafoy lesion at the colorectal anastomosis: A case report.

RATIONALE: The bleeding of Dieulafoy lesion predominantly involves the proximal stomach and leads to severe gastrointestinal bleeding. However, these lesions have also been reported in the whole gastrointestinal tract. Bleeding of Dieulafoy lesions at the anastomosis was seldomly reported and was very easy to be ignored clinically. PATIENT CONCERNS: We describe a 72-year-old woman with a past history of surgery for rectal carcinoma hospitalized with chief complaint of massive rectal bleeding. No gross bleeding lesion was found during the first emergency colonoscopy. Despite multiple blood transfusions, her hemoglobin rapidly dropped to 5.8 g/dL. DIAGNOSIS: She was diagnosed with Dieulafoy lesion at the colorectal anastomosis during the second emergency colonoscopy. INTERVENTIONS: Primary hemostasis was achieved by endoscopic hemostatic clipping. However, she experienced another large volume hematochezia 3 days later, and then received another endoscopic hemostatic clipping. She was improved and discharged. However, this patient underwent hematochezia again 1 month later. Bleeding was arrested successfully after the over-the-scope clip (OTSC) was placed during the fourth emergency colonoscopy. OUTCOMES: This patient underwent 4 endoscopic examinations and treatments during 2 hospitalizations. The lesion was overlooked during the first emergency colonoscopy. The second and third endoscopes revealed Dieulafoy lesion at the colorectal anastomosis and performed endoscopic hemostatic clippings, but delayed rebleeding occurred. The bleeding was stopped after the fourth emergency colonoscopy using OTSC. There was no further rebleeding during hospitalization and after 2-year of follow-up. LESSONS: As far as we know, there is no reported case of lower gastrointestinal bleeding caused by Dieulafoy lesion at the colorectal anastomosis, OTSC is a safe and effective rescue treatment for Dieulafoy lesions.

Surgical Emergencies in Inflammatory Bowel Disease.

Inflammatory bowel disease (IBD) patients are at risk for undergoing emergency surgery for fulminant disease, toxic megacolon, bowel perforation, intestinal obstruction, or uncontrolled gastrointestinal hemorrhage. Unfortunately, medical advancements have failed to significantly decrease rates of emergency surgery for IBD. It is therefore important for all acute care and colorectal surgeons to understand the unique considerations owed to this often-challenging patient population.

Intestinal obstruction as a result of intra-abdominal hematoma: a complication of low molecular weight heparin in pediatric patients. / Obstrucción intestinal por hematoma intraabdominal: una complicación de la heparina de bajo peso molecular en el paciente pediátrico.

INTRODUCTION: Hematomas are a rare cause of intestinal obstruction. Subcutaneous heparin can bring about direct punctures on small bowel loops, potentially leading to traumatic hematoma and intestinal obstruction. CASE REPORTS: We present three cases of pediatric patients with clinical signs of intestinal obstruction treated with subcutaneous heparin. Two cases had increased acute-phase reactants and radiological signs of intestinal suffering, so surgical treatment was decided upon, with intramural hematoma emerging as an intraoperative finding. The third case was conservatively managed with anticoagulant discontinuation and gut rest, since the patient had an adequate general condition and no findings compatible with ischemia or necrosis were noted in the complementary tests. DISCUSSION: The administration of subcutaneous heparin may cause intestinal wall hematomas due to its anticoagulating effect and to the risk of inadvertent punctures on small bowel loops.

INTRODUCCION: Los hematomas son una causa poco frecuente de obstrucción intestinal. La heparina subcutánea tiene riesgo de producir la punción directa de un asa intestinal, provocando un hematoma traumático que genere una obstrucción intestinal. CASOS CLINICOS: Se describen tres casos de pacientes pediátricos con clínica de obstrucción intestinal en tratamiento con heparina subcutánea. Dos casos presentaron elevación de reactantes de fase aguda y signos radiológicos de sufrimiento intestinal por lo que se optó por tratamiento quirúrgico, con el hallazgo intraoperatorio de hematoma intramural. El tercer caso fue manejado de manera conservadora con supresión de la anticoagulación y reposo intestinal, dado el adecuado estado general y ausencia de hallazgos compatibles con isquemia o necrosis en las pruebas complementarias. COMENTARIOS: La administración de heparina subcutánea puede provocar la aparición de hematomas de pared intestinal, tanto por su efecto anticoagulante, como por el riesgo de punción inadvertida de un asa intestinal.

Risk factors and predictive nomograms for bedside emergency endoscopic treatment following endotracheal intubation in cirrhotic patients with esophagogastric variceal bleeding.

Data on emergency endoscopic treatment following endotracheal intubation in patients with esophagogastric variceal bleeding (EGVB) remain limited. This retrospective study aimed to explore the efficacy and risk factors of bedside emergency endoscopic treatment following endotracheal intubation in severe EGVB patients admitted in Intensive Care Unit. A total of 165 EGVB patients were enrolled and allocated to training and validation sets in a randomly stratified manner. Univariate and multivariate logistic regression analyses were used to identify independent risk factors to construct nomograms for predicting the prognosis related to endoscopic hemostasis failure rate and 6-week mortality. In result, white blood cell counts (p = 0.03), Child-Turcotte-Pugh (CTP) score (p = 0.001) and comorbid shock (p = 0.005) were selected as independent clinical predictors of endoscopic hemostasis failure. High CTP score (p = 0.003) and the presence of gastric varices (p = 0.009) were related to early rebleeding after emergency endoscopic treatment. Furthermore, the 6-week mortality was significantly associated with MELD scores (p = 0.002), the presence of hepatic encephalopathy (p = 0.045) and postoperative rebleeding (p < 0.001). Finally, we developed practical nomograms to discern the risk of the emergency endoscopic hemostasis failure and 6-week mortality for EGVB patients. In conclusion, our study may help identify severe EGVB patients with higher hemostasis failure rate or 6-week mortality for earlier implementation of salvage treatments.

Referral for liver transplant following acute variceal bleeding: a multicenter cohort study.

OBJECTIVES: Referral for liver transplant (LT) following acute variceal bleeding (AVB) varies widely. We aimed to characterize and assess its impact on clinical outcomes. METHODS: Observational retrospective cohort including cirrhosis patients with AVB from 3 hospitals in Lisbon, Portugal, from 2018 to 2019. Primary exposure was referral for LT and primary endpoint was all-cause mortality within 2 years of index hospital admission. RESULTS: Among 143 patients, median (IQR) age was 59 (52-72) years and 90 (62.9%) were males. Median (IQR) MELDNa scores on hospital admission and discharge were 15 (11-21) and 13 (10-16), respectively. Overall, 30 (21.0%) patients were assessed for LT, 13 (9.1%) prior to and 17 (11.9%) within 2 years of hospital admission. Overall, 58 (40.6%) patients had at least one potential contra-indication for transplant. LT was performed in 3 (2.1%) patients (among 5 listed). Overall, 34 (23.8%) and 62 (43.4%) patients died at 6 weeks and 2 years post hospital admission, respectively. Following adjustment for confounders, referral for LT was associated with lower 2-year mortality (aHR (95% CI) = 0.20 (0.05-0.85)). CONCLUSION: In a multicenter cohort of cirrhosis patients with AVB, less than a quarter underwent formal LT evaluation. Improved referral for LT following AVB may benefit cirrhosis patients' longer-term mortality.

Study protocol for a Randomised controlled trial of EArly transjugular intrahepatiC porTosystemic stent-shunt in Acute Variceal Bleeding (REACT-AVB trial).

INTRODUCTION: In liver cirrhosis, acute variceal bleeding (AVB) is associated with a 1-year mortality rate of up to 40%. Data on early or pre-emptive transjugular intrahepatic portosystemic stent-shunt (TIPSS) in AVB is inconclusive and may not reflect current management strategies. Randomised controlled trial of EArly transjugular intrahepatiC porTosystemic stent-shunt in AVB (REACT-AVB) aims to investigate the clinical and cost-effectiveness of early TIPSS in patients with cirrhosis and AVB after initial bleeding control. METHODS AND ANALYSIS: REACT-AVB is a multicentre, randomised controlled, open-label, superiority, two-arm, parallel-group trial with an internal pilot. The two interventions allocated randomly 1:1 are early TIPSS within 4 days of diagnostic endoscopy or secondary prophylaxis with endoscopic therapy in combination with non-selective beta blockers. Patients aged ≥18 years with cirrhosis and Child-Pugh Score 7-13 presenting with AVB with endoscopic haemostasis are eligible for inclusion. The primary outcome is transplant-free survival at 1 year post randomisation. Secondary endpoints include transplant-free survival at 6 weeks, rebleeding, serious adverse events, other complications of cirrhosis, Child-Pugh and Model For End-Stage Liver Disease (MELD) scores at 6 and 12 months, health-related quality of life, use of healthcare resources, cost-effectiveness and use of cross-over therapies. The sample size is 294 patients over a 4-year recruitment period, across 30 hospitals in the UK. ETHICS AND DISSEMINATION: Research ethics committee of National Health Service has approved REACT-AVB (reference number: 23/WM/0085). The results will be submitted for publication in a peer-reviewed journal. A lay summary will also be emailed or posted to participants before publication. TRIAL REGISTRATION NUMBER: ISRCTN85274829; protocol version 3.0, 1 July 2023.

Prognosis of LSPD versus TIPS for the treatment of esophagogastric variceal bleeding in cirrhosis.

BACKGROUND: This study aimed to compare postoperative complications in patients with esophagogastric variceal bleeding (EVB) who underwent laparoscopic splenectomy combined with pericardial devascularization (LSPD) versus transjugular intrahepatic portosystemic shunt (TIPS) procedures. METHODS: A retrospective collection of medical records was conducted from January 2014 to May 2020 at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology. The study included patients from the departments of trauma surgery, interventional radiology, and general surgery who were diagnosed with EVB caused by portal hypertension and treated with LSPD or TIPS. Follow-up data were obtained to assess the occurrence of postoperative complications in both groups. RESULTS: A total of 201 patients were included in the study, with 104 cases in the LSPD group and 97 cases in the TIPS group. There was no significant difference in the 1-year and 3-year post-surgery survival rates between the TIPS and LSPD groups (P = 0.669, 0.066). The 3-year survival rate of Child-Pugh B patients in the LSPD group was higher than TIPS group (P = 0.041). The LSPD group also had a significantly higher rate of freedom from rebleeding at 3-year post-surgery compared to the TIPS group (P = 0.038). Stratified analysis showed no statistically significant difference in the rebleeding rate between the two groups. Furthermore, the LSPD group had a higher rate of freedom from overt hepatic encephalopathy at 1-year and 3-year post-surgery compared to the TIPS group (P = 0.007, < 0.001). The LSPD group also had a lower rate of severe complications at 3-year post-surgery compared to the TIPS group (P = 0.020). CONCLUSION: Compared to TIPS, LSPD does not increase the risk of mortality and rebleeding, while demonstrating fewer complications. In patients classified as Child-Pugh A and B, the use of LSPD for treating EVB is both safe and effective.

Learning curve of achieving competency in emergency endoscopy in upper gastrointestinal bleeding: how much experience is necessary?

OBJECTIVES: The management of upper gastrointestinal bleeding (UGIB) has seen rapid advancements with revolutionising innovations. However, insufficient data exist on the necessary number of emergency endoscopies needed to achieve competency in haemostatic interventions. DESIGN: We retrospectively analysed all oesophagogastroduodenoscopies with signs of recent haemorrhage performed between 2015 and 2022 at our university hospital. A learning curve was created by plotting the number of previously performed oesophagogastroduodenoscopies with signs of recent haemorrhage against the treatment failure rate, defined as failed haemostasis, rebleeding and necessary surgical or radiological intervention. RESULTS: The study population included 787 cases with a median age of 66 years. Active bleeding was detected in 576 cases (73.2%). Treatment failure occurred in 225 (28.6%) cases. The learning curve showed a marked decline in treatment failure rates after nine oesophagogastroduodenoscopies had been performed by the respective endoscopists followed by a first plateau between 20 and 50 procedures. A second decline was observed after 51 emergency procedures followed by a second plateau. Endoscopists with experience of <10 emergency procedures had higher treatment failure rates compared with endoscopists with >51 emergency oesophagogastroduodenoscopies performed (p=0.039) or consultants (p=0.041). CONCLUSIONS: Our data suggest that a minimum number of 20 oesophagogastroduodenoscopies with signs of recent haemorrhage is necessary before endoscopists should be considered proficient to perform emergency procedures independently. Endoscopists might be considered as advanced-qualified experts in managing UGIB after a minimum of 50 haemostatic procedure performed. Implementing recommendations on minimum numbers of emergency endoscopies in education programmes of endoscopy trainees could improve their confidence and competency in managing acute UGIB.

Safety and efficacy of transjugular intrahepatic portosystemic shunts vs endoscopic band ligation plus propranolol in patients with cirrhosis with portal vein thrombosis: a systematic review and meta-analysis.

BACKGROUND: This systematic review and meta-analysis aimed to assess the efficacy and safety of transjugular intrahepatic portosystemic shunts (TIPS) against the combined treatment of endoscopic band ligation (EBL) and propranolol in managing patients with cirrhosis diagnosed with portal vein thrombosis (PVT). METHODS: A literature search from inception to September 2023 was performed using MEDLINE, the Cochrane Library, Web of Science, and Scopus. Independent screening, data extraction, and quality assessment were performed. The main measured outcomes were the incidence and recurrence of variceal bleeding (VB), hepatic encephalopathy, and overall survival. RESULTS: A total of 5 studies were included. For variceal eradication, there was initially no significant difference between the groups; however, after sensitivity analysis, a significant effect emerged (risk ratio [RR], 1.55; P < .0001). TIPS was associated with a significant decrease in the incidence of VB (RR, 0.34; P < .0001) and a higher probability of remaining free of VB in the first 2 years after the procedure (first year: RR, 1.41; P < .0001; second year: RR, 1.58; P < .0001). TIPS significantly reduced the incidence of death due to acute GI bleeding compared with EBL + propranolol (RR, 0.37; P = .05). CONCLUSION: TIPS offers a comprehensive therapeutic advantage over the combined EBL and propranolol regimen, especially for patients with cirrhosis with PVT. Its efficacy in variceal eradication, reducing rebleeding, and mitigating death risks due to acute GI bleeding is evident.

Variceal and Nonvariceal Upper Gastrointestinal Bleeding Refractory to Endoscopic Management: Indications and Role of Interventional Radiology.

For over 60 years, diagnostic and interventional radiology have been heavily involved in the evaluation and treatment of patients presenting with gastrointestinal bleeding. For patients who present with upper GI bleeding and have a contraindication to endoscopy or have an unsuccessful attempt at endoscopy for identifying or controlling the bleeding, interventional radiology is often consulted for evaluation and consideration of catheter-based intervention.

Endoscopic Treatment of Small Bowel Bleeding.

Approximately 5% of all gastrointestinal (GI) bleeding originates from the small bowel. Endoscopic therapy of small bowel bleeding should only be undertaken after consideration of the different options, and the risks, benefits, and alternatives of each option. Endoscopic therapy options for small bowel bleeding are like those treatments used for other forms of bleeding in the upper and lower GI tract. Available endoscopic treatment options include thermal therapy (eg, argon plasma coagulation and bipolar cautery), mechanical therapy (eg, hemoclips), and medical therapy (eg, diluted epinephrine injection). Patients with complicated comorbidities would benefit from evaluation and planning of available treatment options, including conservative and/or medical treatments, beyond endoscopic therapy.

Endoscopic Treatment of Acute Esophageal and Gastric Variceal Bleeding.

Acute variceal bleeding is a serious complication of portal hypertension. This most often manifests as bleeding from esophageal varices. Although less likely to occur, bleeding from gastric varices is usually more severe. The best endoscopic management for acute esophageal variceal bleeding is band ligation and this often proves to be definitive therapy for these patients. For gastric variceal bleeding, the best endoscopic therapy is endoscopic cyanoacrylate injection but this can be cumbersome to perform and is not a readily available resource at most centers in the United States.

Surgical Management of Upper Gastrointestinal Bleeding.

The use of surgery in managing upper gastrointestinal (GI) bleeding has rapidly diminished secondary to advances in our understanding of the pathologies that underlie upper GI bleeding, pharmaceutical treatments for peptic ulcer disease, and endoscopic procedures used to gain hemostasis. A surgeon must work collaboratively with gastroenterologist and interventional radiologist to determine when, and what kind of, surgery is appropriate for the patient with upper GI bleeding.
