Surgical repair of endoscopy-induced colonic perforations: a case-matched study of short-term morbidity and mortality.

BACKGROUND: Our aim was to describe the clinical outcomes of surgical interventions performed for the management of colonoscopy-related perforations and to compare these outcomes with those of matched colorectal surgeries performed in elective and emergency settings. METHODS: We included patients with endoscopic colonic perforation who underwent surgical intervention from the 2014-2017 National Surgery Quality Improvement Program participant use data colorectal targeted procedure file. The primary outcome in this study was short term surgical morbidity and mortality. Patients (group 1) were matched with 1:2 ratio to control patients undergoing same surgical interventions for other indications on an elective (group 2) or emergency basis (group 3). Bivariate analysis was conducted to compare categorical variables between the three groups, and multivariate logistic regression was used to evaluate the association between the surgical indication and 30-day postoperative outcomes. RESULTS: A total of 590 patients were included. The average age of the patients was 66.5±13.6 with female gender predominance (381, 64.6%) The majority of patients underwent open colectomy (365, 61.9%) while the rest had suturing (140, 23.7%) and laparoscopic colectomy (85, 14.4%). Overall mortality occurred in 4.1% and no statistically significant difference in mortality was found between the three techniques (P=0.468). Composite morbidity occurred in 163 patients (27.6%). It was significantly lower in laparoscopic colectomy (14.1%) compared to 30.2% and 29.4% in open colectomy and suturing approaches (P=0.014). Patients undergoing colectomy for iatrogenic colonic perforation had less mortality, infection rates and sepsis, as well as bleeding episodes compared to those who had colectomy on an emergent basis. Outcomes were comparable between the former group and patients undergoing elective colectomy for other indications. CONCLUSIONS: Surgical management of colonoscopy related perforations is safe and effective with outcomes that are similar to that of patients undergoing elective colectomy.

A Retrospective Study Comparing the Effect of Conventional Coagulation Parameters Vs. Thromboelastography-Guided Blood Product Utilization in Patients With Major Gastrointestinal Bleeding.

Background: The use of thromboelastography (TEG) has demonstrated decreased blood product utilization in patients with specific etiologies of major gastrointestinal bleeding (GIB), such as variceal and non-variceal bleeding in cirrhosis patients; however, in a non-cirrhosis patient with GIB, there is far less evidence in the literature. Our retrospective study compares the effect of TEG-guided blood product utilization in patients with major GIB with all etiologies, including cirrhosis, admitted to medical intensive care unit (MICU). Methods: A retrospective chart review was conducted on patients admitted to the MICU of a tertiary academic medical center diagnosed with GIB using ICD-9/10 codes from 2014 to 2018. A total of 1,889 patients were identified, and validation criteria such as "GI or hepatology consult note", type and screen, pantoprazole, or octreotide drip" were used, which resulted in 997 patients, out of which 369 had a diagnosis of cirrhosis. Propensity score matching was done for baseline variables (age, sex, and race), ICU length of stay, hospital length of stay, ventilator days, and vasopressor use. As a result, 88 patients were included in the final analysis, with 44 in TEG and 44 in non-TEG group. A sub-group analysis was done in 46 patients with cirrhosis, 23 in TEG group and 23 in non-TEG group after propensity score matching. Results: There was significantly higher total blood volume (4,207 mL vs. 2,568 mL, P = 0.04) in the TEG group as compared to the non-TEG group, including total volume of cryoprecipitate (80 mL vs. 55 mL, P = 0.03) and total volume of platelet (543 mL vs. 327 mL, P = 0.03). In the cirrhosis sub-group, there was no significant difference in the amount of blood products transfused between the two groups. Conclusion: This study revealed that TEG is not superior to conventional coagulation parameters in limiting the volume of blood product transfusion in major GIB patients in ICU settings.

Total esophageal food impaction in the era of the COVID-19 pandemic: a delayed presentation in a patient with Parkinson's disease.

Total esophageal food impaction is extremely rare. We report a patient with Parkinsonism who presented with total dysphagia to solids and liquids and with inability to swallow her saliva of 3 days duration. She did not present sooner as she was afraid of contracting COVID-19 during hospitalization. Chest CT scan revealed total esophageal food impaction. Awake fiberoptic endotracheal intubation followed by EGD and clearance of the impacted food were performed. This patient illustrates esophageal involvement in Parkinson's disease, delayed presentation with an emergency in the COVID-19 era, and the multidisciplinary approach to minimize the risk of aspiration during endoscopy.

Management of acute diarrhea in the emergency department of a tertiary care university medical center.

OBJECTIVES: To examine the management of acute diarrhea in the emergency department (ED) of a large university medical center. METHODS: Retrospective cross-sectional study over a 10-month period of adult patients (age ≥18 years) presenting to the ED with acute diarrhea. RESULTS: Data for 780 patients were reviewed; 101 met the exclusion criteria. Of the 679 patients with acute community-acquired diarrhea, 582 (85.7%) were discharged home and constituted the study cohort of mostly healthy adults (mean age: 32.5 ± 14.5 years). The rate of antibiotic prescription at discharge was 26%. Inappropriate use of antibiotics occurred in 28% of the patients. The presence of fever (odds ratio (OR) = 3.52), leukocytosis (OR = 1.72), and older age (OR = 1.16) were predictors of antibiotic prescription. Patients with dehydration, comorbidities, or bloody diarrhea were more likely to receive antibiotics. Microbiological studies and cross-sectional imaging were ordered in 12.4% and 11.7% of the patients, respectively, but provided very low yield (<10% for both) resulting in significantly higher visit charges. Inappropriately prescribed antibiotics at discharge resulted in higher charges in the ED compared with no antibiotic prescription. CONCLUSION: Acute diarrhea management in our ED is suboptimal and does not adhere to practice guidelines, resulting in unnecessary antibiotic prescriptions, investigations, and cost.

Validation of the new ABC score for predicting 30-day mortality in gastrointestinal bleeding.

BACKGROUND/AIM: The ABC score is a new pre-endoscopic scoring system that was recently developed to accurately predict one-month mortality in upper and lower gastrointestinal bleeding (GIB). We aim to validate this new score on a cohort of Lebanese patients treated in a tertiary care center and to compare it to currently existing scores. METHODS: Adult patients admitted to the American University of Beirut Medical Center (AUBMC) with overt GIB between January 2013 and August 2020 were included. The area under receiver operating characteristic (AUROC) curves of the ABC score in predicting 30-day mortality was calculated using the SPSS software. Other optimal existing scores for predicting mortality (the Oakland score for lower GIB, the AIMS-65 and the Rockall scores for upper GIB)s were also assessed and compared to the ABC score. RESULTS: A total of 310 patients were included in our study. For upper GIB, the ABC score showed good performance in predicting 30-day mortality (AUROC: 0.79), outperforming both the AIMS-65 score (AUROC 0.67, p < 0.001) and the Rockall score (AUROC: 0.62, p < 0.001). For lower GIB, the ABC score also had good performance which was comparable to the Oakland score (AUROC: 0.70 vs 0.56, p = 0.26). CONCLUSION: In our cohort of patients, the ABC score demonstrated good performance in predicting 30-day mortality for patients with upper and lower GIB compared to other established risk scores, which may help guide management decisions. This simple and novel score provides valuable prognostic information for patients presenting with GIB and appears to be reproducible in different patient populations.

First or Second Biologic in Inflammatory Bowel Disease: Combination Therapy or Monotherapy?

The therapeutic armamentarium for patients with inflammatory bowel disease has been expanding. Current guidelines make recommendations about whether patients who are biologic naive should be receiving biologic monotherapy or combination therapy, depending on the class of biologics. However, due to the limited available data, guidance to inform clinical practice for patients receiving their second or more biologic are lacking. We hereby review the available data about the use of biologic monotherapy or combination therapy with concomitant immunomodulator therapies in patients receiving their first as well as those receiving their second biologic.

Large Cameron Ulcer Bleed.

Cameron ulcers usually present with chronic obscure gastrointestinal bleeding. Few cases of life-threatening bleeding have been reported. We hereby present an elderly man who presented with upper gastrointestinal bleeding associated with hemodynamic instability because of a large cratered Cameron ulcer. This ulcer contained a large pseudoaneurysm, and endoscopic therapy was deemed unsafe. The patient had a recurrence of his bleeding, necessitating intervention by our interventional radiology colleagues and then surgical intervention for definitive therapy. This case is important because it familiarizes gastroenterologists with the endoscopic appearance of huge Cameron ulcers and therapeutic options to control hemostasis. It also stresses the importance of a multidisciplinary team approach to ensure the best outcomes for patients.

Patient-Physician Communication in the Era of Mobile Phones and Social Media Apps: Cross-Sectional Observational Study on Lebanese Physicians' Perceptions and Attitudes.

BACKGROUND: The increased prevalence of virtual communication technology, particularly social media, has shifted the physician-patient relationship away from the well-established face-to-face interaction. The views and habits of physicians in Lebanon toward the use of online apps and social media as forms of patient communication have not been previously described. OBJECTIVE: The aim of this study is to describe the views of Lebanese physicians toward the use of social media and other online apps as means of patient communication. METHODS: This was a cross-sectional observational study using an online survey that addressed physicians' perceptions on the use of virtual communication in their clinical practice. The study took place between April and June 2016, and was directed toward physicians at the American University of Beirut Medical Center. RESULTS: A total of 834 doctors received the online survey, with 238 physicians completing the survey. Most of the participants were from medical specialties. Most responders were attending physicians. Less than half of the respondents believed that Web-based apps and social media could be a useful tool for communicating with patients. Email was the most common form of professional online app, followed by WhatsApp (an instant messaging service). The majority of participants felt that this mode of communication can result in medicolegal issues and that it was a breach of privacy. Participants strictly against the use of virtual forms of communication made up 47.5% (113/238) of the study sample. CONCLUSIONS: The majority of physicians at the American University of Beirut Medical Center are reluctant to use virtual communication technology as a form of patient communication. Appropriate policy making and strategies can allow both physicians and patients to communicate virtually in a more secure setting without fear of breaching privacy and confidentiality.
