The week in GI, filtered to what is worth knowing.

Two current US guidelines govern Crohn's disease and should be read together. ACG 2025 (Lichtenstein et al.) remains the reference for diagnosis, mild-to-moderate disease, perianal, postoperative and abscess management. DIAGNOSIS: fecal calprotectin (>50-100 μg/g) separates inflammatory from noninflammatory disease of the colon. Workup is ileocolonoscopy with biopsies, including uninvolved mucosa, plus small-bowel imaging. CTE and MRE are comparable; prefer MRE in patients <35 y and when serial exams are likely. Intestinal ultrasound is an ungraded adjunct. Do routine CRC surveillance in Crohn's colitis. MILD-TO-MODERATE: recommend against oral mesalamine; sulfasalazine only for symptomatic mild colonic CD; ileal-release budesonide 9 mg for induction in ileocecal disease but not for maintenance. MODERATE-TO-SEVERE (AGA Living Guideline, Scott et al., Gastroenterology 2025;169(7):1397-1448, 16 recommendations: 1 strong, 9 conditional, 6 knowledge gaps; updated quarterly, adult outpatients only): RECOMMEND infliximab, adalimumab, ustekinumab, risankizumab, mirikizumab, guselkumab or upadacitinib over no treatment; SUGGEST certolizumab pegol or vedolizumab over no treatment. Advanced-therapy-naive: suggest higher-efficacy agents (infliximab, adalimumab, vedolizumab, ustekinumab, risankizumab, mirikizumab, guselkumab) over lower-efficacy ones (certolizumab pegol, upadacitinib). Prior advanced-therapy (especially anti-TNF) exposure: suggest higher- or intermediate-efficacy agents (adalimumab, risankizumab, guselkumab, upadacitinib; ustekinumab, mirikizumab) over lower-efficacy ones (vedolizumab, certolizumab pegol). Suggest against thiopurine monotherapy for induction; suggest it for maintenance of remission. Suggest SC/IM methotrexate monotherapy; suggest against oral methotrexate. In thiopurine-naive patients starting infliximab, suggest infliximab + thiopurine over infliximab alone. No recommendation on IFX + MTX, adalimumab + immunomodulator, or non-TNF biologic + immunomodulator. After ≥6 months of steroid-free remission on anti-TNF + immunomodulator, suggest withdrawing the immunomodulator and suggest against withdrawing the anti-TNF. SUGGEST upfront advanced therapy over step-up therapy (corticosteroids and/or immunomodulator first). No recommendation on treating to endoscopic vs symptomatic remission. The ACG 2025 moderate-to-severe recommendations (anti-TNF, IFX + thiopurine combination and IL-12/23/IL-23 agents, each strong/moderate; upadacitinib after anti-TNF exposure; steroids for short-term induction only; TPMT/NUDT15 testing before thiopurines) still stand alongside AGA. ACG perianal (infliximab first; drain abscesses and place setons before escalating), postoperative (endoscopy at 6-12 months; anti-TNF strong, vedolizumab conditional in high-risk patients) and intra-abdominal abscess (>2 cm: antibiotics plus drainage, hold immunosuppression) positions are unchanged. THERAPEUTIC ENDOSCOPY (AGA Clinical Practice Update, CGH 2026; details below come from AGA news coverage, not the full text, and are ungraded advice): get cross-sectional imaging before the procedure. Endoscopic balloon dilation is first-line for short strictures (about ≤4-5 cm) with few risk factors (fistula, prestenotic dilation >5 cm, high CRP, prior anti-TNF). Longer or multiple strictures, or ≥3 risk factors, favor surgery.

Outpatient positioning is unchanged from the ACG 2025 UC guideline and the AGA living guideline for moderate-to-severe UC. Confirm UC with endoscopy showing continuous colonic inflammation from the rectum plus histology, after excluding infection with two-step C. difficile testing. Treat mild-moderate disease with 5-ASA chosen by route and extent: suppository for proctitis, enema for left-sided disease, oral plus rectal for extensive disease. If 5-ASA fails, treat as moderate-to-severe rather than stepping up gradually. Position advanced therapy by efficacy tier, not by an anti-TNF-first rule. Advanced-therapy-naive, higher efficacy: infliximab, vedolizumab, ozanimod, etrasimod, upadacitinib, risankizumab, guselkumab. Intermediate: golimumab, ustekinumab, tofacitinib, filgotinib, mirikizumab. Lower: adalimumab. Previously TNF-exposed, higher efficacy: tofacitinib, upadacitinib, ustekinumab. Lower: adalimumab, vedolizumab, ozanimod, etrasimod. After anti-TNF primary non-response, switch mechanism rather than cycling within the class. Treat to target (STRIDE-II): endoscopic improvement, Mayo endoscopic subscore 0-1. Begin CRC surveillance 8-10 years after diagnosis for extensive or left-sided disease; isolated proctitis follows average-risk screening. Inpatient care now follows the 2026 AGA Clinical Practice Update (13 best-practice statements). Admit for severe symptoms refractory to outpatient therapy, suspected complications (obstruction, abscess, toxic megacolon) or significant malnutrition, and identify acute severe UC by Truelove-Witts. Give every patient admitted with diarrhea two-step C. difficile testing. Test for CMV, with early endoscopy, if symptoms worsen, the patient is systemically toxic or disease is steroid-refractory. Give routine VTE prophylaxis with LMWH or fondaparinux unless contraindicated, and individualize post-discharge extension. Give IV methylprednisolone 60 mg/day or equivalent; the AGA living guideline says 40-60 mg/day, and higher doses add no benefit. Do not give adjunctive antibiotics without infection. Involve surgery early. Assess response by day 3 (72 h) using stool frequency and CRP (Oxford criteria); do not continue IV steroids beyond about 7 days without response. Rescue steroid non-responders with infliximab (accelerated or intensified dosing in selected patients with high inflammatory burden or protein-losing colopathy), cyclosporine, or a JAK inhibitor at standard or intensified dosing, or with colectomy. Before discharge, the response should be stable and a transition plan should be in place.

This standard applies to MASLD: hepatic steatosis on imaging or biopsy, at least one cardiometabolic criterion, no other liver disease, and alcohol below the MetALD range. The AGA 2026 MetALD update sets MetALD at about 140-350 g/week of alcohol in women and 210-420 g/week in men, averaged over at least 3 months. MASLD therefore means under about 140 g/week (women) or 210 g/week (men), and drinking above the MetALD range is ALD. Assess alcohol use in every patient with steatotic liver disease at diagnosis and at least once a year, by interview, a validated questionnaire (e.g., AUDIT-C) and/or biomarkers such as phosphatidylethanol (PEth). Advise every patient with steatotic liver disease to stop drinking. Screen people with type 2 diabetes, people with overweight or obesity plus at least one more metabolic risk factor, and anyone with incidental steatosis or raised aminotransferases. Use FIB-4 first. A score below 1.3 (below 2.0 at age 65 or older) is low risk: the patient stays in primary care and repeats FIB-4 every 1-2 years. A score at or above the cutoff goes to a second-line test: VCTE, or ELF if elastography is not available. VCTE below 8 kPa is low risk. VCTE of 8 kPa or more, or ELF of 9.2 or more, means clinically significant fibrosis is likely and the patient should be referred to hepatology. Read liver stiffness with caution if the patient is actively drinking. Reserve biopsy for discordant or unclear results. Lifestyle change is the base of treatment for everyone: at least 5% weight loss improves steatosis, and 10% or more is usually needed for fibrosis to improve. Pharmacotherapy is recommended for adults with non-cirrhotic MASH and F2-F3 fibrosis (by non-invasive tests or biopsy), alongside structured lifestyle intervention and optimised management of comorbidities. The NIT ranges that stand in for F2-F3 differ by society. AASLD uses VCTE 8-15 kPa, MRE 3.1-4.4 kPa or ELF 9.2-10.5. EASL-EASD-EASO 2026 frames the treatable high-risk group as, for example, VCTE 10-20 kPa, MRE 3.1-5.0 kPa or ELF 9.8-11.3. Two drugs are approved: resmetirom (80 mg oral daily, or 100 mg at body weight of 100 kg or more; AASLD Oct 2024 guidance) and semaglutide 2.4 mg subcutaneously once weekly (FDA accelerated approval Aug 2025, AASLD Nov 2025 guidance; in ESSENCE, MASH resolved without fibrosis worsening in 62.9% vs 34.3% on placebo). EASL-EASD-EASO 2026 says to choose between them by patient preference, risks and cardio-renal-metabolic profile. Semaglutide may be preferred with obesity, type 2 diabetes, established cardiovascular disease or high cardiovascular risk. Resmetirom may be prioritised without obesity, or when the patient is already on or cannot tolerate a GLP-1 receptor agonist. On semaglutide, monitoring includes nutrition and sarcopenia assessment, and fibrosis NITs are used over time to judge response. In MASH cirrhosis, resmetirom and semaglutide appear safe but should not be used as MASH-targeted treatment until liver-related benefit is shown. Pioglitazone or vitamin E remain options under the AASLD 2023 guidance. Neither resmetirom nor semaglutide has been formally studied in MetALD. Manage cardiometabolic risk in every patient whatever the fibrosis stage, including statins for ASCVD and control of glucose and blood pressure. On semaglutide, watch for GI side effects and rare risks (AKI, gallbladder disease, pancreatitis, retinopathy, loss of lean mass). For MetALD, treat moderate or severe alcohol use disorder with medication plus behavioural therapy, correct micronutrient deficiencies (folate, thiamine, vitamin D), and do not offer bariatric or endobariatric procedures. HCC surveillance with ultrasound, with or without AFP, every 6 months is indicated only when cirrhosis is present.

Perform a diagnostic paracentesis as soon as possible in any patient with new-onset ascites that can be sampled. Also perform one in any patient with cirrhosis and ascites who is admitted to hospital. AASLD 2021 says this applies to emergent admission for any reason. AGA 2025 BPA 2 names admission for ascites- or encephalopathy-related symptoms. The tap rules out SBP even without signs of infection, because up to one-third of SBP is asymptomatic. Repeat it whenever signs, symptoms or labs suggest infection, and in tense ascites with AKI. Paracentesis is safe with coagulopathy: INR >1.5 or platelets <50×10^9/L is not a contraindication, and routine FFP or platelet transfusion is not recommended. Possible exceptions are DIC, and uremia with thrombocytopenia, where desmopressin may be considered. Initial fluid testing: neutrophil (PMN) count, total protein, and ascitic albumin with a same-day serum albumin to calculate the SAAG. AGA 2025 adds Gram stain and culture to the initial panel for new-onset ascites and hospitalized patients. AASLD 2021 treats culture as part of the SBP workup rather than the routine panel. Either way, inoculate ≥10 mL into aerobic and anaerobic blood-culture bottles at the bedside before antibiotics. Amylase, cytology, glucose, LDH, AFB/ADA and triglycerides are ordered only for a clinical reason. SAAG ≥1.1 g/dL means portal hypertension (~97% accuracy). SAAG <1.1 g/dL points to a non-portal-hypertensive cause: carcinomatosis, TB peritonitis, nephrotic syndrome, pancreatic or chylous ascites. Within high-SAAG ascites, total protein <2.5 g/dL suggests cirrhosis (also massive liver metastases or late Budd-Chiari). Total protein ≥2.5 g/dL suggests a cardiac or postsinusoidal cause (heart failure, portal vein thrombosis, SOS, early Budd-Chiari), so work up with echocardiography, hepatic-vein Doppler or right-heart catheterization. SBP is diagnosed by ascitic PMN >250/mm^3, with or without a positive culture, once a surgically treatable source has been excluded. SBE is diagnosed by pleural fluid PMN >250/mm^3 in a hepatic hydrothorax after pneumonia and other secondary causes are excluded. It is treated with antibiotics and no chest tube.

Diagnose acute pancreatitis (AP) by the Atlanta criteria (2 of 3: characteristic epigastric/LUQ pain, lipase or amylase >3x ULN [lipase preferred for specificity/duration], or characteristic imaging). ACG 2024 stratifies severity risk using SIRS on admission plus bedside risk factors, rising/elevated BUN, rising/elevated hematocrit (>44), obesity (BMI>30), extrapancreatic fluid collections/pleural effusion/infiltrates, altered mental status, and older age/comorbidities, rather than mandating a formal BISAP or APACHE II composite score. Give moderately aggressive lactated Ringer's, most important in the first 6-12 hours, reassessing volume status/BUN/HCT at 6 hours (further aggressive hydration has little added benefit after 24-48h). Start oral low-fat solid food within 24-48h as tolerated in mild disease; if enteral feeding is needed for moderately severe/severe disease, prefer nasogastric over nasojejunal with small-peptide/medium-chain-triglyceride formula and continuous (not bolus/cyclic) feeding; avoid parenteral nutrition if possible. Do not give prophylactic antibiotics, even in severe disease or sterile necrosis; reserve antibiotics for suspected infected necrosis (typically arising 10-14 days in), and choose agents that penetrate pancreatic necrosis while together covering both gut-derived gram-negative enterics and anaerobes, a carbapenem supplies this as monotherapy, whereas a fluoroquinolone or a third-or-higher-generation cephalosporin must be combined with metronidazole; metronidazole alone (anaerobic cover only), or a cephalosporin or a quinolone alone, does not adequately treat infected necrosis. Perform cholecystectomy preferably before discharge for mild acute biliary pancreatitis, and after a second unexplained AP episode even without identified gallstones; reserve ERCP within 24h for AP complicated by cholangitis, with rectal indomethacin +/- pancreatic duct stent and periprocedural hydration to reduce post-ERCP pancreatitis risk. Check triglycerides when gallstones/alcohol are absent (>1000 mg/dL supports a hypertriglyceridemia etiology). For stable pancreatic necrosis, defer surgical, radiological, or endoscopic intervention 4-6 weeks to allow walling-off (step-up approach).

WORKUP (NCCN ESOPH-1): H&P; EGD with biopsy; chest/abdomen CT with oral and IV contrast; pelvis CT with contrast ONLY as clinically indicated; FDG-PET/CT (skull base to mid-thigh) if no evidence of M1 disease; CBC and comprehensive chemistry; EUS if no evidence of M1 or unresectable disease; endoscopic resection (ER) is recommended for accurate staging of early-stage cancers (Tis, T1a, or T1b) and may also be therapeutic; bronchoscopy if the tumor is at or above the carina with no evidence of M1; biopsy of metastatic disease as clinically indicated; assign Siewert category; nutritional assessment and counseling; smoking-cessation counseling; screen for family history. BIOMARKERS: universal MSI (PCR/NGS) or MMR (IHC) testing AND universal PD-L1 testing in ALL newly diagnosed patients; HER2 and CLDN18.2 testing if advanced/metastatic adenocarcinoma is documented or suspected; NGS should be considered. Multidisciplinary evaluation is recommended for stage I-IVA (locoregional) disease (ESOPH-E). ENDOSCOPIC THERAPY (ESOPH-A): the goal of endoscopic therapy (EMR, ESD, and/or ablation) is complete removal or eradication of early-stage disease, pTis, pT1a, and SELECTED superficial pT1b without LVI, plus the pre-neoplastic Barrett's segment. Tis/HGD must first be fully characterized for nodularity, lateral spread and multifocality, with EUS to rule out nodal metastases in select higher-risk cases. Areas of nodularity or ulceration must be RESECTED, not ablated. Completely flat lesions ≤2 cm (squamous HGD/Tis, and BE with flat HGD) should be treated by ER because it gives more accurate histologic assessment; flat lesions >2 cm can be treated by ER but with greater complication risk, and may be treated by ablation alone (data for ablation-alone in squamous HGD are very limited). Lesions pathologically limited to lamina propria/muscularis mucosae (pT1a) or superficial submucosa (pT1b), in the absence of nodal metastases, LVI, or poor differentiation, can be treated with full ER, HOWEVER a thorough patient-and-surgeon discussion of esophagectomy versus the risk of concurrent nodal disease should be undertaken, especially for larger tumors or deeper invasion. Ablation of residual Barrett's should follow ER; complete BE eradication may also be achieved by widefield EMR or ESD at the initial intervention when needed to resect superficial tumor or nodularity ≤2 cm. For SCC, the level of evidence for ablation after ER is LOW; additional ablation may be needed only for multifocal HGD/CIS elsewhere, and may not be needed for completely excised lesions. Endoscopic therapy is 'PREFERRED' for limited early-stage disease: Tis and T1a, ≤2 cm, well or moderately differentiated. Esophagectomy is indicated for extensive carcinoma in situ (pTis/HGD), pT1a, or superficial pT1b, especially nodular disease not adequately controlled endoscopically. PRIMARY TREATMENT, MEDICALLY FIT PATIENTS, ADENOCARCINOMA (ESOPH-13): cT1b-cT2, N0 LOW-RISK (<3 cm, well differentiated) → esophagectomy. cT2 N0 HIGH-RISK (LVI, ≥3 cm, or poorly differentiated), cT1b-cT2 N+, or cT3-cT4a any N → perioperative systemic therapy is PREFERRED (FLOT: 5-FU 2600 mg/m2 IV over 24 h day 1, leucovorin 200 mg/m2, oxaliplatin 85 mg/m2, docetaxel 50 mg/m2, every 14 days, 4 cycles pre- and 4 cycles postoperatively; or FLOT + durvalumab 1500 mg for PD-L1 CPS ≥1 or TAP ≥1%, category 1 for EGJ, category 2A for esophageal adenocarcinoma; note MATTERHORN showed no EFS advantage for durvalumab in diffuse-type disease), QUALIFIER: perioperative therapy is preferred for patients medically fit and with access to frequent toxicity evaluation; preoperative chemoradiation for planned esophagectomy remains an option and may be considered for borderline-resectable patients or patients who are not FLOT candidates (perioperative FOLFOX/CAPOX is another alternative). Consider neoadjuvant or perioperative immune checkpoint inhibitor if the tumor is MSI-H/dMMR (in multidisciplinary consultation; the role of surgery after complete response is unclear). Definitive chemoradiation for patients who are medically unfit/inoperable for surgery or who decline surgery. cT4b → definitive chemoradiation, or chemotherapy alone with invasion of trachea, great vessels, vertebral body, or heart. SQUAMOUS CELL CARCINOMA (ESOPH-2): cT1b-cT2, N0 LOW-RISK (<3 cm, well differentiated) → esophagectomy (non-cervical esophagus). cT2 N0 high-risk (LVI, ≥3 cm, poorly differentiated), cT1b-cT2 N+, or cT3-cT4a any N → PREOPERATIVE CHEMORADIATION is preferred (or definitive chemoradiation). cT4b → definitive chemoradiation, or chemotherapy alone for trachea/great-vessel/vertebral/cardiac invasion. NCCN states explicitly: 'Preoperative chemoradiation is preferred for esophageal SCC.' Preoperative RT dose 41.4-50.4 Gy at 1.8-2.0 Gy/day (23-28 fractions); preferred concurrent regimens include weekly paclitaxel 50 mg/m2 + carboplatin AUC 2 (CROSS, category 1) and fluorouracil + oxaliplatin (category 1). POSTOPERATIVE (ESOPH-F): nivolumab is the preferred postoperative regimen ONLY after PREOPERATIVE CHEMORADIATION with R0 resection and residual pathologic disease (category 1), 240 mg IV every 14 days for 16 weeks, then 480 mg IV every 28 days, maximum treatment duration 1 year. PALLIATION (ESOPH-A/H): esophageal dilation with balloons or bougies for temporary relief of malignant or treatment-related obstruction (avoid overdilation, perforation risk); long-term dysphagia palliation by endoscopic tumor ablation (Nd:YAG laser, PDT, cryoablation) or expandable metal/plastic stents; feeding gastrostomy or jejunostomy for anorexia/dysphagia/malnutrition, but placement of a GASTROSTOMY preoperatively may compromise the gastric vasculature and interfere with gastric-conduit reconstruction and SHOULD BE AVOIDED (feeding jejunostomy is generally preferred for postoperative nutritional support; multidisciplinary expertise is recommended before percutaneous gastrostomy).

Offer anal cancer screening only where there is capacity to perform high-resolution anoscopy (HRA) and to treat what it finds. Screening is RECOMMENDED for: MSM and transgender women with HIV, beginning at age 35; all other people with HIV, and MSM and transgender women without HIV, beginning at age 45; solid organ transplant recipients, beginning 10 years post-transplant; and persons with a history of vulvar HSIL or vulvar cancer, beginning within 1 year of that diagnosis. Screening may be CONSIDERED via shared decision-making, and only where HRA capacity is adequate, for persons aged 45 or older with a history of cervical or vaginal HSIL/cancer, perianal warts, persistent (>1 year) cervical HPV16, or autoimmune conditions. Screen with anal cytology alone, high-risk HPV testing alone (with HPV16 genotyping), or hrHPV-cytology co-testing, all three perform acceptably; HRA is the DIAGNOSTIC procedure for an abnormal screen, not itself a screening test. Perform digital anal rectal examination as part of the physical exam at every screening visit. Refer immediately to HRA for any abnormal cytology, ASC-US or worse, when screening is by cytology alone, since there is no hrHPV result available to triage it; for ASC-US or worse cytology accompanied by a positive hrHPV result on co-testing; for ASC-H or HSIL cytology regardless of HPV result; and for any HPV16-positive result regardless of cytology. Repeat screening in 12 months after NILM cytology alone or a negative HPV test alone, or after ASC-US cytology with negative hrHPV; repeat in 12-24 months after co-testing that is both NILM and hrHPV-negative. Where HRA capacity is reduced, restrict immediate referral to ASC-H/HSIL cytology and to HPV16-positive results, and manage the remainder with repeat screening. Treat HSIL found at HRA-directed biopsy rather than observing it: in ANCHOR, treatment reduced progression to invasive cancer by approximately 57% in people with HIV aged 35 and older.
