Purpose: This study aimed to assess combined effects of early oral feeding after Cesarean section (C/S) under regional anesthesia on bowel function, gastrointestinal complications and surgical recovery. Methods: A systematic literature search was conducted using KISS, RISS, PubMed, CINAHL, EMBASE, CENTRAL and Google Scholar to identify randomized clinical trials comparing early oral feeding (EOF) with delayed oral feeding (DOF) after C/S. Outcome variables were bowel function and gastrointestinal complications and surgical recovery. Effect size was calculated using weighted mean differences (WMDs) and relative risks (RRs), with 95% confidence intervals (CIs). Results: Seven studies involving 1,911 patients from 568 studies, 7 studies were included in meta-analysis. EOF was significantly associated with shorter time to recover bowel movement compared with DOF (WMD, - 2.50; CI, - 3.50~- 1.50). EOF was not associated with nausea (RR, 1.15; CI, 0.87~1.53) and vomiting (RR, 0.96; CI, 0.65~1.42), but lower incidence of abdominal distension (RR, 0.70; CI, 0.50~0.98). EOF was significantly associated with shorter time to discontinuation of intravenous fluids (WMD, - 8.88; 95% CI, - 16.65~- 1.11) and removal of urinary catheter (WMD, - 15.23; CI, - 25.62~- 4.85). Conclusion: This meta-analysis provides evidence that EOF after C/S under regional anesthesia not only accelerates return of bowel function and surgical recovery but also reduces gastrointestinal complications. These results suggest that EOF should be offered to women who have undergone C/S to improve the recovery experience and reduce overall medical costs.

Aortoenteric fistula is a rare but potentially fatal condition causing massive gastrointestinal bleeding. In particular, double primary aortoenteric fistulae are vanishingly rare. We encountered a 75-year-old male patient suffering from abdominal pain, hematochezia, hematemesis, and hypotension. His computed tomography images showed abdominal aortic aneurysm and suspected aortoenteric fistulae. During surgery, we found two primary aortoenteric fistulae. The one fistula was detected between the abdominal aorta and the third portion of the duodenum, and the other fistula was detected between the abdominal aorta and the sigmoid colon. We conducted the closure of the fistulae, the exclusion of the aneurysm, and axillo-bifemoral bypass with a polytetrafluoroethylene graft. The patient was discharged with no complications on the 21st postoperative day.

We report a 10-year-old girl with the blue rubber bleb nevus syndrome (BRBNS) who had chronic severe anemia caused by chronic occult bleeding in the gastrointestinal (GI) tract. The patient was admitted to the hospital frequently for recurrent pallor and fatigue since the age of 7 years. Gastroduodenoscopy and capsule endoscopy revealed multiple venous malformations with blood oozing in the stomach, small bowel and colon. The patient was treated by aggressive surgical resection of the 23 vascular malformations in the GI tract. The patient is well without anemia 15 months post surgery.

Aim: We conducted a case-control matched study to investigate the role of IL-16 gene polymorphisms, rs4072111, rs1131445, rs4778889 and rs11556218, in the risk of gastric cancer in a Chinese population, also performing subgroup analysis by subsites. Methods: To test the hypothesis of involvement, we analyzed the four SNPs of IL16 in 347 cancer patients and 368 controls. Demographic data and other information were collected using a newly designed questionnaire. Genotyping of IL16 (rs4072111, rs1131445, rs4778889 and rs11556218) was performed in a 384-well plate format on the MassARRAY(R) platform. Results: In our study, we found the gastric cancer patients were more likely to be male and have a family history of cancer (P<0.05). We found the rs4778889 CC and rs11556218 GG genotype was significantly associated with 1.97 and 1.84-fold increased risk of non-cardia gastric cancer, while we did not find significant association between the four IL-16 SNPs and cardia gastric cancer. Conclusions: In conclusion, our study indicated that IL-16 rs4778889 CC and rs11556218 GG genotypes are associated with an increased risk of non-cardia gastric cancer in a Chinese population. Our results offer insights into the influence of IL-16 on development of gastric cancer.

Congenital duodenal obstruction is a one of the emergent surgical conditions in neonates. Almost of them were diagnosed with double-bubble sign in prenatal ultrasonography. However, partial obstruction caused from duodenal web could be overlooked. We reported a duodenal web in early childhood. A three-year-old girl visited at our pediatric clinic for constipation. She had been showed non-bilious vomiting after weaning meal since 6 months old of her age, but her weight was relevant for 50-75 percentile of growth curve. Barium enema was initially checked, but any abnormal finding was not found. We noticed the severely distended stomach and 1st portion of duodenum. Upper gastrointestinal series revealed partial obstruction in 2nd portion of duodenum. After laparotomy, we found the transitional zone of duodenum and identified a duodenal web via duodenotomy. We performed duodeno-duodenostomy without any injury of ampulla of Vater. She was recovered uneventfully. During 6 months after operation, she does well without any gastrointestinal symptoms or signs, such as vomiting or constipation.

The incidence of gastroesophageal junction adenocarcinoma (GEJAC) in Western countries has increased in recent decades, in addition to a rise in the incidence of esophageal adenocarcinoma (EAC). Gastroesophageal reflux disease (GERD), obesity, smoking, alcohol consumption, and low Helicobacter pylori (HP) infection rate have been nominated as risk factors for such cancers. Among these risk factors, the increased prevalence of GERD and obesity and the decreased prevalence of HP infection are of special interest owing to the currently increasing prevalence of GEJAC in Western countries. Although similar trends in the prevalence of GERD, obesity, and HP infection are observed in Asian countries after a time lag from Western countries, it is still uncertain if the prevalence of GEJAC in Asian countries is increasing, especially in Korea. The incidence of GERD in Korea is currently increasing; it was below 3% in the 1990s. The incidence of obesity in the Korean population is increasing owing to the adoption of westernized lifestyles, including food preferences, and the HP infection rate in Korea is known to be decreasing. Therefore, based on logical extrapolation of observations of Western countries, the incidence of GEJAC will increase in Korea. However, the proportion of GEJAC among other upper gastrointestinal malignancies in Korea appears to be currently unchanged compared with that in the 1990s. Presently, there is a lack of epidemiologic studies on this issue in this region; therefore, more studies are needed to clarify the characteristics of these tumors and to improve clinical outcomes for patients with these tumors.

In 2019, coronavirus disease (COVID-19), which originated in Wuhan, has spread worldwide. In most people, COVID-19 symptoms are not severe. However, the mortality rate and severity were high in risk groups such as in older people and patients with underlying diseases. As patients with cancer are one of the risk groups, the vaccination for COVID-19 is emphasized in these patients. However, COVID-19 vaccines are not tested enough in special groups such as in patients with cancer because these vaccines are developed at an unprecedented speed. This causes confusion about whether patients undergoing chemotherapy should be vaccinated or not. In this study, international guidelines and studies were reviewed. Most of the studies recommended vaccination. No evidences of any negative effects for the efficacy or safety were recorded in patients undergoing cytotoxic, targeted, and immune agents. However, in critical conditions such as cytopenia, vaccination must be decided according to the patient's condition. COVID-19 vaccines were also recommended for patients on surgery or radiation therapy. If possible, vaccine is given before surgery to avoid confusion between surgical complications and side effects of the vaccine. The radiation recall phenomenon after vaccination has been reported in some cases of radiation therapy. Clinicians should consider these situations before vaccinating each patient. We hope that clearer guidelines will be established by accumulating verified data.

Purpose: Increasing number of older adults are receiving cancer surgeries especially for gastrointestinal cancers, which brings forth attention to age-related postoperative complication prevention. Postoperative delirium (POD) is a common complication that rises after surgical procedures involving general anesthesia, largely in the elderly population. Due to its sudden onset and fluctuating symptoms, POD often goes underdiagnosed and undertreated even though it may lead to various adverse outcomes. POD in GI cancer surgical elderly patients is poorly understood in terms of prevalence, pathophysiology, assessment, treatment and nursing management. We aimed to identify available literature and investigate study results to broaden our understanding of geriatric GI cancer POD. Methods: The search process involved six databases to identify relevant studies abided by inclusion criteria. Results: Eleven studies were selected for this review. Geriatric POD is closely related to frailty and surgical complications. Frailty increases vulnerability to surgical stress and causes cerebral changes that affect stress-regulating neurotransmitter proportions, brain blood flow, vascular density, neuron cell life and intracellular signal transductions. These conditions of frailty result in increased risks of surgical complications such as blood loss, cardiovascular events and inflammation, which all may lead to the POD. Mini Metal State Examination (MMSE), Confusion Assessment Method (CAM) and Delirium Rating Scale-revised-98 (DRS-R-98) are recommended for POD assessment to identify high-risk patients. Conclusion: The POD prevalence ranged from 8.2% to 51.0%. The multifactorial causative mechanism suggests nurses to identify highrisk elderly GI-cancer surgical patients by reviewing patient-specific factors and surgery-specific factors.

Purpose: Gastrointestinal stromal tumors (GISTs) frequently harbor activating gene mutations in either KIT or platelet-derived growth factor receptor A (PDGFRA) and are highly responsive to several selective tyrosine kinase inhibitors. In this study, a targeted next-generation sequencing (NGS) assay with an Oncomine Focus Assay (OFA) panel was used for the genetic characterization of molecular targets in 30 Korean patients with GIST. Materials and Methods: Using the OFA that enables rapid and simultaneous detection of hotspots, single nucleotide variants (SNVs), insertion and deletions (Indels), copy number variants (CNVs), and gene fusions across 52 genes relevant to solid tumors, targeted NGS was performed using genomic DNA extracted from formalin-fixed and paraffin-embedded samples of 30 GISTs. Results: Forty-three hotspot/other likely pathogenic variants (33 SNVs, 8 Indels, and 2 amplifications) in 16 genes were identified in 26 of the 30 GISTs. KIT variants were most frequent (44%, 19/43), followed by 6 variants in PIK3CA, 3 in PDGFRA, 2 each in JAK1 and EGFR, and 1 each in AKT1, ALK, CCND1, CTNNB1, FGFR3, FGFR4, GNA11, GNAQ, JAK3, MET, and SMO. Based on the mutation types, majority of the variants carried missense mutations (60%, 26/43), followed by 8 frameshifts, 6 nonsense, 1 stop-loss, and 2 amplifications. Conclusions: Our study confirmed the advantage of using targeted NGS with a cancer gene panel to efficiently identify mutations associated with GISTs. These findings may provide a molecular genetic basis for developing new drugs targeting these gene mutations for GIST therapy.

Background: The XRCC1 protein facilitates various DNA repair pathways; single-nucleotide polymorphisms (SNPs) in this gene are associated with a risk of gastrointestinal cancer (GIC) with inconsistent results, but no data have been previously reported for the Sabah, North Borneo, population. We accordingly investigated the XRCC1 Arg194Trp and Arg399Gln SNPs in terms of GIC risk in Sabah. Materials and Methods: We performed genotyping for both SNPs for 250 GIC patients and 572 healthy volunteers using a polymerase chain reaction-restriction fragment length polymorphism approach. We validated heterozygosity and homozygosity for both SNPs using direct sequencing. Results: The presence of a variant 194Trp allele in the Arg194Trp SNP was significantly associated with a higher risk of GIC, especially with gastric and colorectal cancers. We additionally found that the variant 399Gln allele in Arg399Gln SNP was associated with a greater risk of developing gastric cancer. Our combined analysis revealed that inheritance of variant alleles in both SNPs increased the GIC risk in Sabah population. Based on our etiological analysis, we found that subjects ${\geq}50years$ and males who carrying the variant 194Trp allele, and Bajau subjects carrying the 399Gln allele had a significantly increased risk of GIC. Conclusions: Our findings suggest that inheritance of variant alleles in XRCC1 Arg194Trp and Arg399Gln SNPs may act as biomarkers for the early detection of GIC, especially for gastric and colorectal cancers in the Sabah population.
