The landscape of chronic liver disease in Egypt has drastically changed over the past few decades. The prevalence of metabolic-associated fatty liver disease (MAFLD) has risen to alarming levels. Despite the magnitude of the problem, no regional guidelines have been developed to tackle this disease. This document provides the clinical practice guidelines of the key Egyptian opinion leaders on MAFLD screening, diagnosis, and management, and covers various aspects in the management of MAFLD. The document considers our local situations and the burden of clinical management for the healthcare sector and is proposed for daily clinical practical use. Particular reference to special groups was done whenever necessary.

REVIEW ARTICLES
Wilson disease in children and young adults - State of the art
p. 21
Atchariya Chanpong, Anil Dhawan
DOI
:10.4103/sjg.sjg_501_21
PMID
:35042319
Wilson disease (WD) is an autosomal recessive disorder caused by mutations of the
ATP7B
gene, with a reported prevalence of 1:30,000–50,000.
ATP7B
encodes an enzyme called transmembrane copper-transporting ATPase, which is essential for copper incorporation into ceruloplasmin and for copper excretion into the bile. A lack or dysfunction of this enzyme results in a progressive accumulation of copper in several organs, especially in the liver, the nervous system, corneas, kidneys, and heart. Children with WD can present with asymptomatic liver disease, cirrhosis, or acute liver failure, with or without neurological and psychiatric symptoms. Approximately 20%–30% of WD patients present with ALF, while most of the other patients have chronic progressive hepatitis or cirrhosis if untreated. Although genetic testing has become a more important diagnostic tool for WD, the diagnosis remains based on both clinical features and laboratory investigations. The aims of treatment are to reduce copper levels and prevent its accumulation in the liver and other organs, especially in the central nervous system. Liver transplantation in WD is a life-saving option for patients presenting with liver failure and encephalopathy. For WD patients treated with chelating agents, adherence to the therapy is essential for long-term success. In this review, we also address specific issues in young adults as compared to children.

ORIGINAL ARTICLES
Development and validation of a predictive model for feeding intolerance in intensive care unit patients with sepsis
p. 32
Kunlin Hu, Xin lei Deng, Lin Han, Shulin Xiang, Bin Xiong, Liao Pinhu
DOI
:10.4103/sjg.sjg_286_21
PMID
:34528519
Background:
Feeding intolerance in patients with sepsis is associated with a lower enteral nutrition (EN) intake and worse clinical outcomes. The aim of this study was to develop and validate a predictive model for enteral feeding intolerance in the intensive care unit patients with sepsis.
Methods:
In this dual-center, retrospective, case-control study, a total of 195 intensive care unit patients with sepsis were enrolled from June 2018 to June 2020. Data of 124 patients for 27 clinical indicators from one hospital were used to train the model, and data from 71 patients from another hospital were used to assess the external predictive performance. The predictive models included logistic regression, naive Bayesian, random forest, gradient boosting tree, and deep learning (multilayer artificial neural network) models.
Results:
Eighty-six (44.1%) patients were diagnosed with enteral feeding intolerance. The deep learning model achieved the best performance, with areas under the receiver operating characteristic curve of 0.82 (95% confidence interval = 0.74–0.90) and 0.79 (95% confidence interval = 0.68–0.89) in the training and external sets, respectively. The deep learning model showed good calibration; based on the decision curve analysis, the model's clinical benefit was considered useful. Lower respiratory tract infection was the most important contributing factor, followed by peptide EN and shock.
Conclusions:
The new prediction model based on deep learning can effectively predict enteral feeding intolerance in intensive care unit patients with sepsis. Simple clinical information such as infection site, nutrient type, and septic shock can be useful in stratifying a septic patient's risk of EN intolerance.

Water immersion sigmoidoscopy versus standard insufflation for colorectal cancer screening: A cohort study
p. 39
Calcedonio Calcara, Paolo Aseni, Keith Siau, Pietro Gambitta, Sergio Cadoni
DOI
:10.4103/sjg.sjg_198_21
PMID
:34494603
Background:
Although the efficacy of water-assisted colonoscopy is well established, the role of water immersion sigmoidoscopy (WIS) remains unclear. We compared WIS with carbon dioxide insufflation sigmoidoscopy (CO
2
S) on patient outcomes.
Methods:
We conducted an analysis of prospectively collected data from a single-center quality improvement program about patients undergoing unsedated screening sigmoidoscopy (WIS and CO
2
S) between May 2019 and January 2020. Outcomes studied included the following: Rates of severe pain <17% (score of ≥7 on a numeric rating scale of 0–10, and on a Likert scale), willingness to repeat the procedure without sedation, adequate bowel cleanliness >75% (proportion of Boston Bowel Preparation Scale score: 2–3) and adenoma detection rate (ADR).
Results:
In total, 234 patients (111 WIS; 123 CO
2
S) were included. All patients were aged 58 years and 58.9% were female; baseline characteristics were comparable between groups. There were no significant differences in rates of severe pain (WIS: 16.5%, CO
2
S: 13.8%;
P
= 0.586), willingness to repeat the unsedated procedure (WIS: 82.3%, CO
2
S: 84.5%;
P
= 0.713), adequate bowel cleanliness (WIS: 78.4%, CO
2
S: 78%,
P
= 0.999) or ADR (WIS: 25.2%, CO
2
S: 16.3%;
P
= 0.106) between groups. However, average procedure times were longer with WIS (9.06 min) compared to CO
2
S (6.45 min;
P
< 0.001). Overall, 29.6% of women reported that they would repeat sigmoidoscopy only if sedated.
Conclusions:
WIS does not ameliorate tolerance to and quality of sigmoidoscopy screening measured by several scores. When offered a choice, the women's willingness to repeat WIS or CO
2
S without sedation was poor and raises concern on the opportunity of screening sigmoidoscopy without sedation in these subjects.

Comparison of channel sampling methods and brush heads in surveillance culture of endoscope reprocessing: A propensity score matching and paired study
p. 46
Xue-Yue Ji, Pei-Yong Ning, Chun-Nan Fei, Jia Song, Xue-Mei Dou, Nan-Nan Zhang, Jun Liu, He Liu
DOI
:10.4103/sjg.sjg_437_21
PMID
:34856726
Background:
Endoscopy-related infections have caused multiple outbreaks. The importance of surveillance culture is gradually recognized, but sampling techniques are not consistent in many guidelines. It is unclear whether the Flush-Brush-Flush sampling method (FBFSM) is more sensitive than the conventional flush sampling method (CFSM) and whether different sampling brushes have different effects.
Methods:
The propensity score matching method was done with two matching ways, 1:1 nearest neighbor propensity score matching and full matching was used to analyze the surveillance culture data collected by FBFSM and CFSM. We fit a confounder-adjusted multiple generalized linear logistic regression model to estimate the marginal odds ratio (OR). A paired study was applied to compare the sampling effect of polyurethane foam (PU) head brush and polyamide (PA) head brush.
Result:
From 2016 to 2020, 316 reprocessed endoscope samples were collected from all 59 endoscopy centers in Tianjin. About 279 (88.3%) reprocessed endoscopes met the threshold of Chinese national standards (<20 CFU/Channel). The qualified rate of reprocessed endoscopes sampling by CFSM (91.8%) and FBFSM (81.6%) was statistically different (p < 0.05). The adjusted OR by full matching for FBFSM was 7.98 (95% confidence interval: 3.35-21.78). Forty one pairs of colonoscopes, after reprocessing from 27 centers, were tested by PA and PU brushes, and no difference was found in microbial recovery.
Conclusion:
FBFSM was confirmed to be a more sensitive sampling technique. PU and PA brushes had no significant difference in sampling effect.

Continuous infusion of lidocaine in pediatric colonoscopy: A randomized double-blind placebo-controlled study
p. 54
Chao Yuan, Chengli Wang, Jiayao Wu, Ningyang Gao, Kunwei Li, Yongle Li, Xizhao Huang, Wei Huang, Zurong Hu
DOI
:10.4103/sjg.sjg_275_21
PMID
:34806658
Background:
Propofol is commonly used for providing procedural sedation during pediatric colonoscopy. Intravenous (
i.v
.) lidocaine can mitigate visceral pain and reduce propofol requirements during surgery. The aim of this study is to investigate the effect of i.v. lidocaine on perioperative propofol and sufentanil dose, pulse oxygen saturation, postoperative pain score, and recovery time during pediatric colonoscopy.
Methods:
We designed a randomized, double-blind, placebo-controlled study and enrolled 40 children aged from 3 to 10 years who underwent colonoscopy. After titration of propofol to achieve unconsciousness, the patients were given
i.v
. lidocaine (1.5 mg/kg later 2 mg/kg
/
hour) or the same volume of saline. Sedation was standardized and combined propofol with sufentanil. The primary outcome variables were intraoperative propofol and sufentanil requirements, and the number of oxygen desaturation episodes. Secondary outcome variables were recovery time after colonoscopy and post-colonoscopy pain.
Results:
Lidocaine infusion resulted in a significant reduction in propofol requirements: (median (quartile) 1.8 (1.5-2.0) vs. 3.0 (2.8-3.3) mg/kg respectively;
P
< 0.001) and sufentanil requirements: (median (quartile) 0.06 (0.05-0.08) vs. 0.1 (0.1-0.1) μg/kg respectively;
P
< 0.001). The number of subjects who experienced oxygen desaturation below 95% in the lidocaine group was also significantly less than that in the control group: 1 vs. 6 (
P
= 0.04). The mean (SD) recovery time was significantly shorter in the lidocaine group: (19.2 (2.6) vs. 13.3 (2.6) min respectively;
P
< 0.001). There was no significant difference in post-colonoscopy pain.
Conclusion:
Continuous infusion of lidocaine resulted in reduction of propofol and sufentanil requirements, recovery time, and risk of hypoxemia during pediatric colonoscopy.

Is the nuclear factor kappa-b (NF-κB) pathway and inflammatory status associated with colorectal cancer?
p. 60
Büşra Atabilen, Gamze Akbulut, Merve Bacanli, Doğan Uncu
DOI
:10.4103/sjg.sjg_44_21
PMID
:34380870
Background:
Although genetic predisposition has a role in the etiology of colorectal cancer, there are many other factors that affect its development. In this study, it was aimed to evaluate the NF-κB pathway, inflammatory status and dietary antioxidant capacity in individuals with colorectal cancer.
Methods:
The study was carried out with 40 male subjects diagnosed with colorectal cancer aged between 39-65, years and a control group of the same number of healthy men. Subjects in the case and control groups were subdivided according to body mass index (BMI), as normal (BMI 20-24.9 kg/m
2
) or overweight/obese (BMI ≥25 kg/m
2
).
Results:
At the end of the study, NF-κB and interleukin-22 levels were higher in the case group, but no significant difference was found between the groups. Interleukin-23 and 8-Hydroxy-2-deoxyguanosine levels in the case group classified as overweight/obese according to BMI were significantly higher than in the control group (
P
= 0.001 and
P
< 0.001, respectively). Considering diet antioxidant capacity, it was higher in individuals in the control group than in the case group. However, there was no significant difference between the groups.
Conclusion:
Inflammatory status and reduced dietary antioxidant capacity are risk factors in the development of colorectal cancer.

Comparison of cold snare polypectomy and endoscopic mucosal resection for 3–10-mm colorectal polyps in end-stage renal disease patients
p. 67
Chang Kyo Oh, Ho Soon Choi, Young-Seok Cho
DOI
:10.4103/sjg.sjg_371_21
PMID
:34755710
Background
: Patients with end-stage renal disease (ESRD) have a higher incidence of clinically relevant complications, such as bleeding and perforation after polyp resection, compared to patients without underlying diseases. Cold snare polypectomy (CSP) is increasingly used for the removal of small polyps and diminutive polyps due to its shorter procedure time and low risk of bleeding and perforation. However, there have been few studies on the effectiveness and safety of CSP in patients with ESRD. The aim of this study was to compare the efficacy and safety of CSP and endoscopic mucosal resection (EMR) in ESRD patients.
Methods
: This study was a retrospective study. We performed propensity score-matched analysis in patients with ESRD who underwent endoscopic resection for 3–10-mm-sized colorectal polyps at Seoul St. Mary's Hospital, from January 2014 to December 2019.
Results
: After 1:1 ratio matching, 406 polyps were included: 203 polyps were resected with CSP and 203 polyps with EMR. There was no difference between the CSP group and EMR group in incomplete resection rate (4.43% vs. 1.97%,
P
= 0.16). There were no differences between the CSP and EMR group for immediate bleeding (5.42% vs. 7.88%,
P
= 0.32) and delayed bleeding (0% vs. 0.49%,
P
= 1.00). No perforation occurred in either group.
Conclusions
: There were no differences between the CSP and EMR group in terms of efficacy and safety. CSP can be one of the standard methods for the removal of 3–10-mm-sized colorectal polyps in patients with ESRD.

p. 74
Abed Al Lehibi, Shaimaa Elkholy, Mohamed Gouda, Ammar Al Dabbagh, Areej Al Balkhi, Abdullah Almtawa, Nawwaf Al Otaibi, Mohammed El-Sherbiny, Kareem Essam, Mohammed Attieh Alzahrani, Ahmed Al Ghamdi, Adel Al Ghamdi, Ahmad AlEid, Adel Qutub, Abdulrahman Alamr, Shameem Ahmad, Khalid Al Sayari, Bashaar Al Ibrahim, Abdullah Al Khathlan, Resheed Eid Alkhiari
DOI
:10.4103/sjg.sjg_49_21
PMID
:34259191
Background:
Peroral endoscopic myotomy (POEM) was proposed in 2010 as a minimally invasive procedure for the treatment of achalasia. In this article, we describe the Middle Eastern experience with the procedure in terms of efficacy, length of admission, and short- and long-term complications.
Methods:
A retrospective analysis of our prospectively collected data on patients who underwent a POEM procedure was conducted between March 2019 and May 2020. The primary outcome was clinical success rate, defined as a postprocedure Eckardt score ≤3 at ≥3 months. Secondary outcomes included the length of hospital stay, presence of reflux symptoms or need for proton pump inhibitors (PPIs) ≥3 months, and adverse events.
Results:
During the study period, 67 patients (35 females) underwent the procedure for achalasia. The participants' ages ranged from 11 to 80 years (mean 41 ± 18 years). Eckardt scores before the treatment ranged between 4 and 12 (mean 8.85 ± 1.75). Sixty-four patients (95.5%) achieved Eckardt scores of ≤3 at ≥3 months after the procedure (95% confidence interval [CI]: 91%–100%). The difference between pre- and post-procedural Eckardt scores averaged around -8 points (95% CI: −7.5 to -8.5
P
< 0.0001). Adverse events were reported in 24 patients (35.8%) and included pneumoperitoneum (32.8%), reflux symptoms at 3 months (29.9%), and surgical emphysema (3%). Six patients had adverse events that led to prolongation of admission; 3% of whom had aspiration pneumonia, 3% had pneumoperitoneum, 1.5% had both, and 1.5% had an esophageal tear.
Conclusions:
POEM is a promising procedure for the treatment of achalasia with a high clinical success rate, short hospital admission, and a reassuring safety profile.
