Pain is the predominant symptom troubling patients. Pain management is one of the most important aspects in the management of surgical patients leading to early recovery from surgical procedures or in patients with chronic diseases or malignancy. Various groups of drugs are used for dealing with this; however, they have their own implications in the form of adverse effects and dependence. In this article, we review the concerns of different pain-relieving medicines used postoperatively in gastrointestinal surgery and for malignant and chronic diseases...

Liver transplantation (LT) in patients with hepatocellular carcinoma (HCC) and chronic liver disease (CLD) is limited by factors such as tumor size, number, portal venous or hepatic venous invasion and extrahepatic disease. Although previously established criteria, such as Milan or UCSF, have been relaxed globally to accommodate more potential recipients with comparable 5-year outcomes, there is still a subset of the population that has advanced HCC with or without portal vein tumor thrombosis without detectable extrahepatic spread who do not qualify or are unable to be downstaged by conventional methods and do not qualify for liver transplantation...

BACKGROUND: Functional constipation (FC) is a common gastrointestinal disorder characterized by abdominal pain and bloating, which can greatly affect the quality of life of patients. Conventional treatments often yield suboptimal results, leading to the exploration of alternative therapeutic approaches. AIM: To evaluate the efficacy of KiwiBiotic in the management of FC and related symptoms. METHODS: This prospective, interventional, single-center, crossover study compared the safety and effectiveness of KiwiBiotic® vs psyllium husk in managing FC, abdominal pain, and bloating...

Clostridium difficile infection (CDI) has been increasing due to the effect of recurrent hospitalizations. The use of antibiotics has been shown to alter the gut microbiome and lead to CDIs. The treatment is limited to three major antibiotics; however, the incidence of recurrent CDIs has been increasing and drug resistance is a major concern. This aspect is a growing concern in modern medicine especially in the elderly population, critical care patients, and immunocompromised individuals who are at high risk of developing CDIs...

BACKGROUND: The gastrointestinal symptom rating scale (GSRS) is a questionnaire in English language which is designed to assess the clinical symptoms in patients with irritable bowel syndrome (IBS) and peptic ulcer disease. This validated scale has questions on around 15 items and has been validated in patients with dyspepsia and IBS. AIM: To translate and validate the English version of the GSRS questionnaire to the Hindi version. METHODS: The purpose of the present work was to create a Hindi version of this questionnaire for use in the Indian population...

Biliary complications like cholelithiasis and choledocholithiasis are more common in bariatric surgery patients due to obesity and rapid weight loss. Patients with a body mass index > 40 face an eightfold risk of developing cholelithiasis. Post-bariatric surgery, especially after laparoscopic Roux-en-Y gastric bypass (LRYGB), 30% of patients develop biliary disease due to rapid weight loss. The aim of this review is to analyze the main biliary complications that occur after bariatric surgery and its management...

BACKGROUND: Peptic ulcer disease (PUD) remains a significant healthcare burden, contributing to morbidity and mortality worldwide. Despite advancements in therapies, its prevalence persists, particularly in regions with widespread nonsteroidal anti-inflammatory drugs (NSAIDs) use and Helicobacter pylori infection. AIM: To comprehensively analyse the risk factors and outcomes of PUD-related upper gastrointestinal (GI) bleeding in Pakistani population. METHODS: This retrospective cohort study included 142 patients with peptic ulcer bleeding who underwent upper GI endoscopy from January to December 2022...

BACKGROUND: Irritable bowel syndrome (IBS), defined according to the Rome IV diagnostic criteria, is a chronic functional gastrointestinal disorder characterized by recurrent abdominal pain related to altered bowel habits. First-line recommended treatments are limited to combining drugs targeting predominant symptoms, particularly pain (antispasmodics), constipation (laxatives), and diarrhea (loperamide), yielding only a limited therapeutic gain. GASTRAP® DIRECT is a class IIa medical formulation composed of a combination of chitin-glucan and simethicone indicated for the symptomatic treatment of gas-related gastrointestinal disorders by combining different mechanisms of action...

A treat-to-target strategy in inflammatory bowel disease (IBD) involves treatment intensification in order to achieve a pre-determined endpoint. Such uniform and tight disease control has been demonstrated to improve clinical outcomes compared to treatment driven by a clinician's subjective assessment of symptoms. However, choice of treatment endpoints remains a challenge in management of IBD via a treat-to-target strategy. The treatment endpoints for ulcerative colitis (UC), recommended by the Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE) consensus have changed somewhat over time...

Irritable bowel syndrome with diarrhea is a very frequent clinical condition characterized by disabling intestinal symptoms. This disease presents with daily abdominal pain for at least 3 months related to defecation and associated with a change in the frequency of bowel movements and the shape of the stool. International surveys about this disease report a global prevalence of about 1.5%. A new amino acid based electrolyte solution has recently been commercialized for oral rehydration in diarrhea. It is composed of water, electrolytes, and five selected amino acids that function as sodium co-transporters without containing glucose...

BACKGROUND: Amino-acid based medical foods have shown promise in alleviating symptoms of drug induced gastrointestinal side effects; particularly, diarrhea-predominant symptoms. Irritable bowel syndrome (IBS) is a gastrointestinal disorder that affects up to 9% of people globally, with diarrhea predominant IBS (IBS-D) being the most prevalent subtype. Further trials are needed to explore potential added benefits when integrated into standard care for IBS-D. AIM: To assess the effectiveness of an amino acid-based medical food as an adjunct to standard of care for adults with IBS-D...

BACKGROUND: Highly effective and well-tolerated direct-acting antiviral (DAA) therapies have revolutionised the management of hepatitis C virus (HCV); however, niche populations face treatment barriers. DAAs co-prescribed with several first-generation anti-epileptic drugs (AEDs) are contraindicated due to drug-drug interactions. A common example is carbamazepine whereby steady-state carbamazepine reduces the maximum concentration and area under the curve of velpatasvir, glecaprevir and pibrentasvir due to potent cytochrome P450 (CYP) 3A4 induction...

Fluid therapy/resuscitation is mandatory in acute pancreatitis due to the pathophysiology of fluid loss as a consequence of the inflammatory process. For many years, without clear evidence, early and aggressive fluid resuscitation with crystalloid solutions (normal saline solution or Ringer lactate solution) was recommended. Recently, many randomized control trials and meta-analyses on fluid therapy have revealed that high fluid rate infusion is associated with increased mortality and severe adverse events compared to those resulting from moderate fluid rates, and this has triggered a paradigm shift in fluid management strategies...

BACKGROUND: Slow transit constipation (STC) is a disorder with delayed colonic transit. Cinnamic acid (CA) is an organic acid in natural plants, such as Radix Scrophulariae (Xuan Shen), with low toxicity and biological activities to modulate the intestinal microbiome. AIM: To explore the potential effects of CA on the intestinal microbiome and the primary endogenous metabolites-short-chain fatty acids (SCFAs) and evaluate the therapeutic effects of CA in STC. METHODS: Loperamide was applied to induce STC in mice...

In this commentary, we summarize some of the key points of the original paper "Timing of percutaneous endoscopic gastrostomy tube placement in post-stroke patients does not impact mortality, complications, or outcomes" and offer support for the proposed results. Specifically, we address how early percutaneous endoscopic gastrostomy (PEG) tube placement may reduce hospital length of stay and costs. We also discuss topics related to the article including PEG weaning and post-stroke nutritional formulation. However, we note that concerns purported by previous studies that early PEG placement may worsen outcomes are not fully addressed, and further research is needed...

BACKGROUND: Obscure small bowel bleeding is defined as gastrointestinal bleeding (GIB) that is unidentifiable with esophagogastroduodenoscopy and a colonoscopy with video capsule endoscopy (VCE) being the next gold standard step for evaluation. Small bowel transit time (SBTT) is a metric of a VCE study that is defined as the time the capsule takes to travel through the small intestine. AIM: To determine if SBTT within the VCE study, correlates to overall detection of obscure small bowel bleeds...

BACKGROUND: In monotherapy studies for bleeding peptic ulcers, large volumes of epinephrine were associated with a reduction in rebleeding. However, the impact of epinephrine volume in patients treated with combination endoscopic therapy remains unclear. AIM: To assess whether epinephrine volume was associated with bleeding outcomes in individuals who also received endoscopic thermal therapy and/or clipping. METHODS: Data from 132 patients with Forrest class Ia, Ib, and IIa peptic ulcers were reviewed...

BACKGROUND: Percutaneous Endoscopic Gastrostomy (PEG) tubes are often placed for dysphagia following a stroke in order to maintain sufficient caloric intake. The 2011 ASGE guidelines recommend delaying PEG tube placement for two weeks, as half of patients with dysphagia improve within 2 wk. There are few studies comparing outcomes based on timing of PEG tube placement, and there is increasing demand for early PEG tube placement to meet requirements for timely discharge to rehab and skilled nursing facilities...

BACKGROUND: Low bone mineral density (BMD) is common in patients with inflammatory bowel disease. However, nutritional risk factors for low BMD in the ulcerative colitis (UC) population are still poorly understood. AIM: To investigate the association of anthropometric indicators and body composition with BMD in patients with UC. METHODS: This is a cross-sectional study on adult UC patients of both genders who were followed on an outpatient basis...

Biliary atresia (BA) and choledochal cysts are diseases of the intrahepatic and extrahepatic biliary tree. While their exact etiopathogeneses are not known, they should be treated promptly due to the potential for irreversible parenchymal liver disease. A diagnosis of BA may be easy or complicated, but should not be delayed. BA is always treated surgically, and performing the surgery before the age of 2 mo greatly increases its effectiveness and extends the time until the need for liver transplantation arises...
