Background: Esophageal cancer is comprised of adenocarcinoma and squamous cell carcinoma and is the sixth leading cause of cancer-related mortality worldwide. Upper endoscopy may reveal a partially or completely lumen-occluding mass at diagnosis, yet the prognostic significance of such a presentation is not clear.

Objectives: To investigate whether endoscopic obstructing lesions have a meaning regarding patient prognosis.

Methods: We reviewed upper gastrointestinal endoscopic studies performed over a 20-year period (2000–2020). We compared overall survival, disease stage, histologic criteria, and anatomic location of the lesions in esophagus lumen-obstructing and non-obstructing tumors. Differences between the two groups were statistically evaluated.

Results: Sixty-nine patients were diagnosed with histologically confirmed esophageal cancer. As assessed through endoscopy, 32/69 (46%) patients had obstructive and 37/69 (54%) had non-obstructive cancers. Median survival was significantly shorter in the lumen-obstructing lesions compared with the non-obstructing lesions (3.5 months vs. 10 months, P = 0.001). Female median survival displayed a trend toward shorter survival compared to males (3.5 months vs. 10 months, P = 0.059). There was no statistically significant difference in the percentages of advanced, stage IV disease in the obstructive group and the non-obstructive group (11/32 [34.3%] and 14/37 [37.8%], respectively P = 0.80).

Conclusions: Obstructive esophageal cancers predict shorter median overall survival compared with non-obstructive cancers, without any correlation between obstruction of the lesion and tumor metastatic stage.

Background: Polyp detection rate (PDR) is a convenient quality measure indicator. Many factors influence PDR, including the patient's background, age, referral (ambulatory or hospitalized), and bowel cleansing.

Objectives: To evaluate whether years of professional experience have any effect on PDR.

Methods: A multivariate analysis of a retrospective cohort was performed, where both patient- and examiner-related variables, including the experience of doctors and nurses, were evaluated. PDR, as the dependent variable was calculated separately for all (APDR), proximal (PPDR), and small (SPDR) polyps.

Results: Between 1998 and 2019, 20,996 patients underwent colonoscopy at a single center. After controlling for covariates, the experience of both doctors and nurses was not found to be associated with APDR (odds ratio [OR] 0.99, 95% confidence interval [95%CI] 0.98–1.00, P = 0.15 and OR 1.03, 95%CI 1.02–1.04, P < 0.0001, respectively). However, after 2.4 years of colonoscopy experience for doctors, and 9.5 years of experience for nurses, a significant increase in APDR was observed. Furthermore, results revealed no association for PPDR and SPDR, as well.

Conclusions: Years of colonoscopy experience for both doctors and assisting nurses were not associated with APDR, PPDR, and SPDR. In doctors with 2.4 years of experience and nurses with 9.5 years of experience, a significant increase in APDR was observed.

Background: Non-alcoholic fatty liver disease (NAFLD) is emerging as an important public health condition. The effect of Ramadan fasting on several metabolic conditions has been previously assessed.

Objectives: To assess the impact of Ramadan fasting on non-alcoholic steatohepatitis (NASH) severity scores.

Methods: A retrospective, case control study was conducted in Nazareth Hospital between 2017 and 2019. We included NAFLD patients who had been diagnosed by abdominal ultrasonography. The study population was divided in two matched groups: NASH subjects who fasted all of Ramadan and NAFLD/NASH subjects who did not fast (control). Metabolic/NASH severity scores, homeostatic model assessment of β-cell function and insulin resistance (HOMA-IR), NAFLD Fibrosis Score (NFS), BARD scores, and fibrosis-4 (FIB4) scores were assessed in both groups before and after the Ramadan month.

Results: The study included 155 NASH subjects, 74 who fasted and 81 who did not. Among the fasting group, body mass index decreased from 36.7 ± 7.1 to 34.5 ± 6.8 after fasting (P < 0.003), NFS declined from 0.45 ± 0.25 to 0.23 ± 0.21 (P < 0.005), BARD scores declined from 2.3 ± 0.98 to 1.6 ± 1.01 (P < 0.005), and FIB4 scores declined from 1.93 ± 0.76 to 1.34 ± 0.871 (P < 0.005). C-reactive protein decreased from 14.2 ± 7.1 to 7.18 ± 6.45 (P < 0.005). Moreover, HOMA-IR improved from 2.92 ± 1.22 to 2.15 ± 1.13 (P < 0.005).

Conclusions: Ramadan fasting improved on inflammatory markers, insulin sensitivity, and noninvasive measures for NASH severity assessment.

Background: While the routine performance of terminal ileum (TI) intubation during colonoscopy procedures is perceived to have a low yield, its utility during colonoscopies performed for specific indications have not been well studied.

Objectives: To assess the diagnostic yield of an indication-based ileoscopy in real-life practice.

Methods: The authors reviewed endoscopic reports of patients who underwent colonoscopies over an 8-year period (2011–2018) and had routine ileoscopy during these procedures. Demographic data, indications for colonoscopy, and endoscopic findings were documented. Diagnostic yield and odds ratio for TI findings were calculated.

Results: Over 30,000 colonoscopy reports performed during the study period were reviewed. Ilesocopy was performed in 1800 patients, 216 patients had findings in the TI (ileitis or ulcers). TI findings were more prevalent in younger ages (38.3 ± 17.6 vs. 43.6 ± 20, P < 0.05). The greatest yield of ileoscopy was evident when performed for the evaluation of chronic abdominal pain and diarrhea (14.4% vs. 9.3%, odds ratio [OR] 1.62, P < 0.05). Positive fecal occult blood test (FOBT) (OR 0.1, 95% confidence interval [95%CI] 0.02–0.5, P = 0.005) and constipation (OR 0.44, 95%CI 0.2–0.9, P = 0.04) were negatively associated with TI findings.

Conclusions: Ileoscopy may have the greatest utility in evaluating suspected inflammatory bowel disease (IBD) patients, but may not add value to the evaluation of constipation and positive FOBT

Background: Bariatric surgery has become the most common and effective therapeutic option for obesity. However, it is associated with morbidity and complications. Identification of predictors for surgical complications is an unmet need.

Objectives: To determine a simple non-invasive parameter that predicts early postoperative complications following bariatric surgery.

Methods: In this retrospective study of all patients who underwent elective bariatric surgery at Nazareth Hospital EMMS during a 4-year period (2015–2018). We collected clinical and laboratory parameters and determined predictors of complications.

Results: A total of 345 patients underwent bariatric surgery during the study period. Of the patients, 51 experienced early post-bariatric surgery complications as compared to 294 patients who had no complications. Univariate analysis revealed that neutrophil-to-lymphocyte ratio (NLR) (odds ratio [OR] 1.912, P < 0.0001) and platelet to lymphocyte ratio (OR 1.015, P < 0.0001) were associated with post-bariatric surgery complications. In a multivariate logistic regression analysis, only NLR remained a significant predictor (OR 1.751, 95% confidence interval 1.264–2.425, P = 0.0008) with a receiver operating characteristic curve for NLR of 0.8404.

Conclusions: We found that the NLR predicts post bariatric surgery early complications. Further prospective studies are needed to validate our findings.
