In this editorial we comment on an article published in a recent issue of the World J Gastrointest Surg . A common gene mutation in gastric cancer (GC) is the TP53 mutation. As a tumor suppressor gene, TP53 is implicated in more than half of all tumor occurrences. TP53 gene mutations in GC tissue may be related with clinical pathological aspects. The TP53 mutation arose late in the progression of GC and aided in the final switch to malignancy. CDH1 encodes E-cadherin, which is involved in cell-to-cell adhesion, epithelial structure maintenance, cell polarity, differentiation, and intracellular signaling pathway modulation...

In this editorial, we review the article published in World J Gastrointest Oncol 2019, 11: 1031-1042. We specifically focus on the occurrence, clinical characteristics, and risk factors of fluoropyrimidine drug-related cardiotoxicity in patients with gastrointestinal tumors. Despite significant advancements in diagnostic and therapeutic techniques that have reduced mortality rates associated with digestive system tumors, the incidence and mortality rates of treatment-related cardiotoxicity have been increasing, severely impacting the survival and prognosis of cancer patients...

This study aimed at determining whether there is a difference in the safety profile between fast release (FR) aspirin tablets and regular galenic formulations of aspirin. This study was based on a clinical study database pool (Bayer HealthCare) including 84 clinical studies and 16,095 human subjects. The meta-analysis included 72 studies applying a single dose of aspirin of at most 1000 mg and was, therefore, based on individual data from 9288 subjects. Of these, 6029 subjects took aspirin and 3259 subjects took placebo...

BACKGROUND: Superior mesenteric artery syndrome (SMAS), also known as Wilkie's syndrome, is a rare disease that mainly presents as intestinal obstruction with a variable incidence ranging from 0.013 to 0.3% (Salehzadeh et al. in Case Rep Gastrointest Med, 2019, 10.1155/2019/3458601). In this syndrome, the third part of the duodenum, located between the abdominal aorta and the superior mesenteric artery, is wholly or partially obstructed (Mosalli et al. in J Pediatr Surg 46:e29-31, 2011)...

INTRODUCTION: Lower Gastro intestinal bleeding (LGIB) is one of the most important clinical symptoms which have significant morbidity and mortality. It has an annual admission rate of 0.15% with mortality rate of 5-10%. LGIB can be caused by number of causes which includes both neoplastic and non-neoplastic lesions. Colonoscopy is the gold standard diagnostic measure which is simple, convenient and cost effective procedure. The present study was aimed to assess the Colonoscopic profile of LGIB presenting to our tertiary care centre in south India...

INTRODUCTION: Cyanoacrylate glue injection has become standard of care for acutely bleeding as well as for primary and secondary prophylaxis of high risk gastric varices. There is limited data on safe and effective amount of glue injected. Our study was aimed to fulfill the gap. MATERIALS: It was retrospective analysis of endoscopy laboratory chart, videos and corresponding case sheets of all consecutive endoscopies January to September 2022. Number, type and size of gastric varices, amount of glue injected and outcomes (technical success, intra procedural and post-procedural complications) were noted...

OBJECTIVES: Computed tomography has become a critical component in evaluating adult patients with acute caustic ingestions and an alternative to endoscopy for detecting transmural gastrointestinal necrosis. This study assessed the performance and reliability of computed tomography findings of transmural gastrointestinal necrosis, given that the presence of the disease potentially signifies the need for surgery. METHODS: A retrospective database search was performed to identify consecutive adult patients with acute caustic ingestions who had computed tomography with endoscopy or surgery within 72 h of admission...

Clostridioides difficile infection (CDI) is a global health problem. The association of appendectomy on the severity and prognosis of CDI has been reported in many literatures, but there are still contradictions. In a retrospective study entitled "Patients with Closterium diffuse infection and prior appendectomy may be prone to word outcomes" published in World J Gastrointest Surg 2021, the author found that prior appendectomy affects the severity of CDI. Appendectomy may be a risk factor for increasing the severity of CDI...

The following letter to the editor highlights the review titled "Inflammatory bowel disease-related colorectal cancer: Past, present and future perspectives" in World J Gastrointest Oncol 2022 March 15; 14(3): 547-567. It is necessary to explore the role of inflammation in promoting tumorigenesis and development of gastrointestinal cancers.

Liver transplantation (LT) withstands as the most preferred therapeutic option for patients afflicted with hepatocellular carcinoma (HCC) and cirrhosis. To improve prognosis post-transplant, as well as to prevent the occurrence of rejection, a life-long immunosuppression strategy is implemented. The following letter to the editor highlights and provides novel evidence from recently published literature on topics discussed within the review article titled "Trends of rapamycin in survival benefits of liver transplantation for hepatocellular carcinoma" in World J Gastrointest Surg 2021; 13: 953-966...

BACKGROUND: Prophylactic abdominal drainage is current standard practice after distal pancreatectomy (DP), with the aim to divert pancreatic fluid in case of a postoperative pancreatic fistula (POPF) aimed to prevent further complications as bleeding. Whereas POPF after pancreatoduodenectomy, by definition, involves infection due to anastomotic dehiscence, a POPF after DP is essentially sterile since the bowel is not opened and no anastomoses are created. Routine drainage after DP could potentially be omitted and this could even be beneficial because of the hypothetical prevention of drain-induced infections (Fisher, Surgery 52:205-22, 2018)...

We report that rat stomach perforation (surgery with 5-mm diameter metal needle on the ventral side in the prepyloric area) induced a defect that would not heal. Also, stomach perforation rapidly induced the intracranial hypertension (superior sagittal sinus), portal and caval hypertension and aortal hypotension. Stable gastric pentadecapeptide BPC 157 largely attenuated or eliminated these pressure disturbances. Finally, BPC 157 completely healed stomach defect. Previously, BPC 157 largely attenuated or even eliminated the consequences of Budd-Chiari syndrome in rats, in particular, portal and caval hypertension and aortal hypotension, and then, huge thrombosis in both veins and arteries, and multiple organ dysfunction syndrome, heart, lung, liver, kidney and gastrointestinal lesions...

Several common hereditary disorders are associated with toxic iron overload which leads to liver cirrhosis, cardiomyopathy, and endocrine disorders. Hereditary hemochromatosis arises from mutations in the genes coding for any of several proteins involved in iron sensing (e.g. Hfe), hepcidin production (e.g. hemojuvelin), or hepcidin action, resulting in elevated iron absorption relative to the iron need. Divalent metal-ion transporter-1 (DMT1) is a H+ -coupled Fe2+ transporter and the principal or only mechanism by which nonheme iron is taken up at the intestinal brush border [Shawki A et al (2015) Am J Physiol Gastrointest Liver Physiol 309, G635-G647]...

Lymphoproliferative diseases arise when the physiological mechanisms that control the proliferation of T and B lymphocytes are disrupted, resulting in an uncontrolled and autonomous increase in immune cells leading to lymphocytosis and lymphadenopathy, and often to the involvement of extranodal sites. The differential diagnosis of malignant T cell tumors involves other neoplasms and non-clonal T cell proliferations. Immunological markers are essential, as a first step, to distinguish between T-cell and non-T-cell disorders...

BACKGROUND: Laparoscopic left hepatectomy with resection of the Spiegel lobe remains a technically demanding procedure as it is a deep-seated area surrounding the inferior vena cava (IVC). Mobilization of the Spiegel lobe requires safe exposure of the ventral side of the IVC while dissecting the short hepatic veins from the IVC. Additionally, wide space is needed to isolate the left Glissonean pedicle (Glt). We used a modified caudate lobe-first approach to overcome this challenge Maeda (J Hepato-Bil Pancreat Sci 25:335-41, 2018), Li (J Gastrointest Surg 23:1084-5, 2019), Homma (Surg Endosc 33:3851-7, 2019)...

BACKGROUND: It is difficult to laparoscopically approach tumors of the anatomically anomalous right lobe of the liver, such as cranially protruded liver. The intercostal port has been useful for laparoscopic hepatectomy, especially for tumors located in the dome of the liver. PLoS One. 15:e0234919; Surg Endosc. 31:1280-1286; J Gastrointest Surg. 21:2135-2143; J Hepatobiliary Pancreat Sci. 21:E65-68; Surg Oncol. 38:101576; Thus, we introduce our technique using triple intercostal transthoracic ports for laparoscopic hepatectomy for hepatocellular carcinoma located in segment 8...

The following letter to the editor highlights the review titled "Liquid biopsy in cholangiocarcinoma: Current status and future perspective" in World J Gastrointest Oncol 2021; 13: 332-350. It is necessary to realize individualized therapy to improve the clinical prognosis of patients with cholangiocarcinoma.

BACKGROUND: Walled-off pancreatic necrosis (WON) represents delayed sequelae of necrotizing pancreatitis, generally developing in 5-15% of cases 4 weeks after the initial attack (Boškoski and Costamagna Ann Gastroenterol 27(2):93-94, 2014). They are characterized by a well-circumscribed, encapsulated collection of necrotic parenchyma with variable degree of gland liquefaction (Boškoski and Costamagna Ann Gastroenterol 27(2):93-94, 2014, Khreiss et al. J Gastrointest Surg 19(8):1441-1448, 2015)...
