If a patient with a history of gallstones experiences RUQ pain along with elevated inflammatory markers, it is more likely to be acute cholecystitis or cholangitis rather than biliary colic. The presence of fever and abnormal LFTs suggests ascending cholangitis, as opposed to cholecystitis, which is indicated by Charcot’s triad of RUQ pain, fever, and jaundice. Acute pancreatitis is unlikely if amylase levels are normal, and the sudden onset of symptoms makes malignancy, particularly cholangiocarcinoma, less probable.

Understanding Ascending Cholangitis

Ascending cholangitis is a bacterial infection that affects the biliary tree, with E. coli being the most common culprit. This condition is often associated with gallstones, which can predispose individuals to the infection. Patients with ascending cholangitis may present with Charcot’s triad, which includes fever, right upper quadrant pain, and jaundice. However, this triad is only present in 20-50% of cases. Other common symptoms include hypotension and confusion. In severe cases, Reynolds’ pentad may be observed, which includes the additional symptoms of hypotension and confusion.

To diagnose ascending cholangitis, ultrasound is typically used as a first-line investigation to look for bile duct dilation and stones. Raised inflammatory markers may also be observed. Treatment involves intravenous antibiotics and endoscopic retrograde cholangiopancreatography (ERCP) after 24-48 hours to relieve any obstruction.

Overall, ascending cholangitis is a serious condition that requires prompt diagnosis and treatment. Understanding the symptoms and risk factors associated with this condition can help individuals seek medical attention early and improve their chances of a successful recovery.

The appropriate surgical procedure for a patient with rectal cancer on the anal verge is abdominoperineal excision of the rectum. This procedure involves the removal of the anus, rectum, and a section of the sigmoid colon. Symptoms of rectal cancer include blood mixed with stools, changes in bowel habits, and copious mucus in stools. Haemorrhoidectomy is not the correct choice for this patient as the diagnosis is unlike. High anterior resection is used for upper rectal tumours, while low anterior resection is used for low rectal tumours, but not for anal verge tumours. Rubber band ligation is used to treat haemorrhoids in outpatient clinics, which is not the diagnosis for this patient.

Colorectal cancer is typically diagnosed through CT scans and colonoscopies or CT colonography. Patients with tumors below the peritoneal reflection should also undergo MRI to evaluate their mesorectum. Once staging is complete, a treatment plan is formulated by a dedicated colorectal MDT meeting.

For colon cancer, surgery is the primary treatment option, with resectional surgery being the only cure. The procedure is tailored to the patient and tumor location, with lymphatic chains being resected based on arterial supply. Anastomosis is the preferred method of restoring continuity, but in some cases, an end stoma may be necessary. Chemotherapy is often offered to patients with risk factors for disease recurrence.

Rectal cancer management differs from colon cancer due to the rectum’s anatomical location. Tumors can be surgically resected with either an anterior resection or an abdomino-perineal excision of rectum (APER). A meticulous dissection of the mesorectal fat and lymph nodes is integral to the procedure. Neoadjuvant radiotherapy is often offered to patients prior to resectional surgery, and those with obstructing rectal cancer should have a defunctioning loop colostomy.

Segmental resections based on blood supply and lymphatic drainage are the primary operations for cancer. The type of resection and anastomosis depend on the site of cancer. In emergency situations where the bowel has perforated, an end colostomy is often safer. Left-sided resections are more risky, but ileo-colic anastomoses are relatively safe even in the emergency setting and do not need to be defunctioned.

Management of New-Onset Dyspepsia in a Middle-Aged Patient

When a middle-aged patient presents with new-onset dyspepsia, it is important to take a thorough clinical history to rule out more serious conditions such as malignancy. A 4-week course of full-dose PPI is typically recommended, although there is no clear evidence on whether this or Helicobacter pylori testing should be done first. If PPIs are used, a 2-week washout period is necessary before testing for H. pylori to avoid false-negative results.

While alginate preparations like Gaviscon® can be used to inhibit gastric acid reflux, it may be more appropriate to increase the PPI dose if the patient has already experienced some improvement with this medication. However, if the patient exhibits ‘red flag’ symptoms like gastrointestinal bleeding, anorexia, weight loss, dysphagia, or the presence of an epigastric mass, urgent endoscopy is necessary. Endoscopy is also recommended for patients over 55 with persistent, unexplained dyspepsia that has not responded well to PPIs.

Finally, while this patient’s BMI is on the higher end of the healthy range, referral to a dietician is unlikely to be necessary unless there are specific concerns about weight loss measures. Overall, a comprehensive approach to managing new-onset dyspepsia in middle-aged patients involves careful consideration of symptoms, medication options, and potential underlying conditions.

Differential Diagnosis for Abdominal Pain: Chronic Mesenteric Ischaemia, Chronic Pancreatitis, Diverticulitis, Gastric Cancer, and Acute Mesenteric Ischaemic Embolism

Abdominal pain is a common presenting symptom in clinical practice, and it can be caused by a variety of conditions. In this article, we will discuss the differential diagnosis for abdominal pain, including chronic mesenteric ischaemia (CMI), chronic pancreatitis, diverticulitis, gastric cancer, and acute mesenteric ischaemic embolism.

CMI usually results from atherosclerotic disease of two or more mesenteric vessels, while chronic pancreatitis is characterised by a continuing, chronic, inflammatory process of the pancreas. Diverticulitis is an inflammation of one or more diverticula, while gastric cancer is the third most common cause of cancer-related death in the world. Acute mesenteric ischaemic embolism is characterised by pain that is disproportionate to physical examination findings.

Each condition has its own unique set of symptoms and clinical presentation. By understanding the differential diagnosis for abdominal pain, clinicians can make an accurate diagnosis and provide appropriate treatment for their patients.

Management of Dyspepsia in Primary Care: Guidelines and Recommendations

Dyspepsia is a common complaint in primary care, encompassing a range of symptoms such as epigastric pain, heartburn, acid regurgitation, bloating, nausea, and vomiting. Here are some guidelines and recommendations for managing dyspepsia in primary care:

One-month trial of full-dose PPI: NICE guidelines recommend offering empirical full-dose PPI therapy for 4 weeks to patients with dyspepsia. Helicobacter pylori testing should also be offered, but a 2-week washout PPI-free period is necessary before testing.

Helicobater pylori stool test and routine referral for OGD: In young patients with no risk factors and relatively benign history and physical findings, routine referral for an endoscopy or testing for Barrett’s esophagus is not necessary.

Long-term low-dose PPI: If symptoms recur after initial treatment, offering a PPI at the lowest dose possible to control symptoms would be appropriate. H2 receptor antagonist therapy should be considered if there is an inadequate response to a PPI.

Refer urgently for OGD: Patients presenting with dyspepsia and significant acute GI bleeding should be referred for same-day assessment to a specialist. Other reasons for urgent referral would be the suspicion of malignancy, which in young patients with no red flag symptoms would be unwarranted.

Triple therapy for Helicobacter pylori eradication: Testing for Helicobacter pylori should be offered to patients with dyspepsia after a 2-week washout PPI-free period. It would be inappropriate to initiate triple therapy treatment without a positive test result first.

In summary, dyspepsia in the general population in primary care is defined broadly to include patients with recurrent epigastric pain, heartburn or acid regurgitation, with or without bloating, nausea, or vomiting. Management should follow evidence-based guidelines and recommendations to ensure appropriate and effective treatment.

Understanding Geographic Tongue: Symptoms, Causes, and Management

Geographic tongue is a common and benign condition that affects the tongue. It is characterized by irregular, smooth, red patches with a white border that resemble a map. While some individuals may experience pain or discomfort, others may not have any symptoms at all. The cause of geographic tongue is unknown, and there is currently no cure. However, symptomatic pain relief and avoidance of certain triggers may help manage the condition.

It is important to differentiate geographic tongue from other oral conditions such as oral candidiasis, oral leukoplakia, and vitamin deficiencies. Oral candidiasis can present with white/yellow plaques that can be easily removed, while oral leukoplakia presents with painless white plaques that cannot be easily scraped away and may be pre-malignant. Vitamin deficiencies such as B12 and C can also cause oral symptoms.

Overall, geographic tongue is a harmless condition that primarily affects females. While it may cause discomfort for some individuals, it does not pose any serious health risks. If you are experiencing symptoms of geographic tongue, it is recommended to seek advice from a healthcare professional for proper diagnosis and management.

Understanding and Managing Irritable Bowel Syndrome (IBS)

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder that affects 10-20% of the population, with women being more likely to develop it than men. It is characterized by abdominal pain, bloating, and altered bowel habits without any specific organic pathology.

Diagnosis of IBS is based on the presence of symptoms such as abdominal pain or discomfort, bloating, and change in bowel habit for at least 6 months. Physical examination and further investigations are necessary to exclude other differential diagnoses.

Management of IBS primarily involves psychological support and dietary measures such as fiber supplementation, low FODMAP diets, increased water intake, and avoiding trigger foods. Pharmacological treatment is adjunctive and should be directed at symptoms. Anti-spasmodics, anti-diarrheals, and antidepressants may have a positive effect on symptoms.

It is important to note that symptoms not consistent with IBS, such as rectal bleeding, anorexia/weight loss, nocturnal symptoms, or fecal incontinence, should alert the clinician to the possibility of an organic pathology. Referral for psychological therapies should be considered for patients who do not respond to pharmacological treatments after 12 months and who develop a continuing symptom profile.

Treatment Options for Primary Biliary Cholangitis

Primary biliary cholangitis (PBC) is a liver disease that can lead to cirrhosis if left untreated. Ursodeoxycholic acid (UDCA) is the main treatment for PBC, as it can prevent or delay the development of cirrhosis. UDCA increases bile flow, inhibits toxic bile acid production, prevents hepatocyte apoptosis, and reduces the liver’s immune response. However, UDCA may cause side effects such as diarrhea, nausea, and thinning hair.

Spironolactone is a diuretic that can be useful for end-stage liver disease with ascites, but it is not indicated for treating fatigue in PBC patients. Aspirin and ibuprofen should be avoided by PBC patients, as they can worsen liver disease. Cholestyramine is used for cholestatic itching, but it should not be taken with UDCA as it can prevent UDCA absorption.

In summary, UDCA is the primary treatment for PBC, and other medications should be used with caution and only for specific symptoms or complications.

Ulcerative colitis can be managed through inducing and maintaining remission. The severity of the condition is classified as mild, moderate, or severe based on the number of stools and presence of systemic upset. Treatment for mild-to-moderate cases of proctitis involves using topical aminosalicylate, while proctosigmoiditis and left-sided ulcerative colitis may require a combination of oral and topical medications. Extensive disease may require a high-dose oral aminosalicylate and topical treatment. Severe colitis should be treated in a hospital with intravenous steroids or ciclosporin. Maintaining remission can involve using a low maintenance dose of an oral aminosalicylate or oral azathioprine/mercaptopurine. Methotrexate is not recommended, but probiotics may prevent relapse in mild to moderate cases.

Abnormal liver function tests in the context of obesity may suggest the presence of non-alcoholic fatty liver disease.

Non-Alcoholic Fatty Liver Disease: Causes, Features, and Management

Non-alcoholic fatty liver disease (NAFLD) is a prevalent liver disease in developed countries, primarily caused by obesity. It encompasses a range of conditions, from simple steatosis (fat accumulation in the liver) to steatohepatitis (fat with inflammation) and may progress to fibrosis and liver cirrhosis. Insulin resistance is believed to be the primary mechanism leading to steatosis, making NAFLD a hepatic manifestation of metabolic syndrome. Non-alcoholic steatohepatitis (NASH) is a type of liver damage similar to alcoholic hepatitis but occurs in the absence of alcohol abuse. It affects around 3-4% of the general population and may be responsible for some cases of cryptogenic cirrhosis.

NAFLD is usually asymptomatic, but hepatomegaly, increased echogenicity on ultrasound, and elevated ALT levels are common features. The enhanced liver fibrosis (ELF) blood test is recommended by NICE to check for advanced fibrosis in patients with incidental NAFLD. If the ELF blood test is not available, non-invasive tests such as the FIB4 score or NAFLD fibrosis score, in combination with a FibroScan, may be used to assess the severity of fibrosis. Patients with advanced fibrosis should be referred to a liver specialist for further evaluation, which may include a liver biopsy to stage the disease more accurately.

The mainstay of NAFLD treatment is lifestyle changes, particularly weight loss, and monitoring. Research is ongoing into the role of gastric banding and insulin-sensitizing drugs such as metformin and pioglitazone. While there is no evidence to support screening for NAFLD in adults, NICE guidelines recommend the management of incidental NAFLD findings.
