Small intestinal bacterial overgrowth (SIBO) is a clinical condition characterized by a malabsorption syndrome due to an increase in microorganisms within the small intestine. The main mechanisms restricting bacterial colonization in the upper gut are the gastric acid barrier, mucosal and systemic immunity and intestinal clearance. When these mechanisms fail, bacterial overgrowth develops. Diarrhea, steatorrhea, chronic abdominal pain, bloating and flatulence are common symptoms and are similar to those observed in irritable bowel syndrome. Breath tests (glucose and/or lactulose breath tests) have been proposed as a sensitive and simple tool for the diagnosis of bacterial overgrowth, being non-invasive and inexpensive compared to the gold standard represented by the culture of intestinal aspirates. Antibiotic therapy is the cornerstone of SIBO treatment. Current SIBO treatment is based on empirical courses of broad-spectrum antibiotics since few controlled studies concerning the choice and duration of antibiotic therapy are available at present.

The diagnosis and treatment of patients with pancreatic strictures presents a multitude of clinical challenges. The etiology of pancreatic strictures is varied, including benign strictures subsequent to acute pancreatitis, trauma, postsurgical, post-endoscopic retrograde cholangiopancreatography (ERCP), and malignancy. Patients with strictures usually present with symptoms of recurrent pancreatitis, abdominal pain, weight loss, and/or steatorrhea. The absence of a prior history of pancreatitis or surgery increases the likelihood of malignancy. High-quality imaging studies of the pancreas, CT, MRI/magnetic resonance cholangiopancreatography, or endoscopic ultrasound (EUS) scanning are utilized for better definition. Imaging detects an associated mass and/or demonstrates the ductal anatomy. Invasive procedures such as ERCP are performed to better define the causal relationships of the patient's symptoms or to obtain tissue diagnosis. Treatment goals include ameliorating symptoms, dilating the stricture, and ruling out cancer. The risk of malignancy underlies much of the intervention, which includes serology, cytologic analysis, and serial imaging. EUS has become the procedure of choice to rule out a mass, to evaluate the parenchyma for evidence of chronic pancreatitis, and to obtain fine-needle biopsies for tissue confirmation. In symptomatic patients or patients with indeterminate strictures, ERCP is used for direct pancreatography, tissue acquisition, and endoscopic treatment. Endotherapy includes sphincterotomy, dilation, and stenting to provide drainage. We view ERCP as the optimal first-line treatment modality. ERCP offers the potential of curative treatment and is less invasive than surgery, especially as some patients' symptoms are not severe enough to justify surgery. If patients do not experience relief of symptoms after several sessions of endoscopic therapy, surgery is the logical next step for definitive, long-term treatment.

Chronic pancreatitis (CP) is characterized by progressive, chronic inflammation of the pancreas, resulting in loss of exocrine and endocrine function and chronic abdominal pain. In most cases, CP is induced by long-term alcoholism. The second most frequent diagnosis is idiopathic CP, in the absence of known causes of CP. However, the identification of genetic and immunological causes continuously reduces the number of cases classified as idiopathic pancreatitis. Common symptoms of CP comprise abdominal pain radiating to the back, diarrhea, steatorrhea and the development of diabetes. The diagnosis is mainly based on clinical features, typical morphological findings such as pancreatic calcifications, duct stenoses and dilatations, as well as pathologic pancreatic function tests. Treatment of CP includes watch and wait strategies in asymptomatic patients, symptomatic treatment of the clinical features such as pain, exocrine and endocrine insufficiency, as well as interventional or surgical therapy of complications such as pseudocysts, pancreatic duct stenosis, stones or biliary obstruction.

The disease referred to eponymically as Whipple's disease (WD) in medical literature was thoroughly described by the American physician and pathologist George Hoyot Whipple (1878-1976) in 1907 and given a temporary denomination of "intestinal lipodystrophy". According to literature, WD is rare, but its precise incidence has not yet been established. Familial incidence of the disease is acknowledged, and its immunogenetic pathogenesis is assumed. The incidence ofWD is prevailingly observed in middle-aged men (mean age 55), exceptionally at child age - the ratio being 3 to 6 for men and women, respectively. 1. Clinical diagnosis is based on symptoms in the GIT region and, in rare cases, on extraintestinal symptoms. Clinical symptomatology includes: abdominal pain with persistent diarrhoea (steatorrhoea), symptoms typical of malabsorption connected with weight loss, fevers, polyarthritic symptoms, swollen lymph nodes and, in part of patients, skin hyperpigmentation. Anaemia and hypoalbuminaemia (reduced IgA) are typically detected in laboratory tests. Rarer extraintestinal symptoms of the disease are of a diverse nature: cardiac lesions, cerebral lesions, ocular symptoms, conspicuous or even tumour-like enlargement of lymph nodes, lesions of the hemopoietic system. The clinical course ofWD is of progressive or remittent nature and the disease is fatal without treatment. Long-term therapy with antibiotics, especially a combination oftetracyclines (doxycyclin) and corticoids (dexametazone), or chloramphenicol in case of cerebral lesion, have a significantly positive effect on the course and prognosis of WD. From the point of view of pathology, WD is a multisystem infectious disease (Tropheryma whipplei) primarily affecting the GIT (39, 47, 52, 103) or different extraintestinal locations. Due to the known diversity of clinical symptoms, no clinical-diagnostic standard has been established for WD. Differential diagnosis includes different multisystem diseases, primarily malignant lymphomas (especially Hodgkin's disease). From the pathogenetic point of view, we can either assume the effect of a particular cytokine (or TNFalpha) activating macrophage phagocytosis or, if its production is normal, a disorder or defect of the respective receptor in the macrophage cellular membrane. The identification of "Whipple's bacteria" - Tropheryma whipplei - gen. nov. et sp. nov. was made possible by modern molecular biology research methodologies. Its cultivation allows both for the acquisition of the specific antibody and of detailed knowledge of its genoma (PCR, 16S rRNA sequencing).

Early diagnosis and curative resection are significant predictors of survival in patients with pancreatic cancer. We hypothesize that cholecystectomy within 12 months of pancreatic cancer affects 1-year survival. The Surveillance Epidemiology and End Result (SEER) database linked to Medicare data was used to identify patients diagnosed with pancreatic cancer who underwent cholecystectomy 1 to 12 months prior to cancer diagnosis. The SEER database identified 32,569 patients from 1995 to 2002; 415 (1.3%) underwent cholecystectomy prior to cancer diagnosis. Patients who underwent cholecystectomy had a higher proportion of diabetes (40.2% vs 20.5%; P < 0.01), obesity (8.9% vs 3.1%; P < 0.01), jaundice (17.3% vs 0.7%; P < 0.01), cholelithiasis (70.4% vs 4.2%; P < 0.01), choledocholithiasis (0.7% vs 0.0%; P < 0.01), weight loss (17.3% vs 4.7%; P < 0.01), abdominal pain (79.5% vs 22.5%), steatorrhea (0.7% vs 0.0%; P < 0.01), and cholecystitis (32.3% vs 1.7% ; P < 0.0001). After controlling for tumor stage, patient demographics, and symptoms, survival at 1 year was significantly lower in patients undergoing cholecystectomy (OR, 0.75; 95% CI, 0.58-0.97). Recent cholecystectomy is associated with decreased 1-year survival among patients with pancreatic cancer. For patients older than 65 years of age, further evaluation prior to cholecystectomy may be necessary to exclude pancreatic cancer, especially patients with jaundice, weight loss, and steatorrhea.

Pancreatoblastoma (PB) is extremely rare. A 11-year-old boy, who had excision of dilated common bile duct with hepaticoduodenostomy when 9 years old was referred to our institute for further management of abdominal pain and steatorrhea. Imaging studies showed a solid 4 cm tumor in the head of the pancreas and two lesions in the liver. Needle biopsies diagnosed PB with liver metastases. After five courses of chemotherapy, the primary tumor was completely resected with pancreaticoduodenectomy (PD) and Child's pancreaticobiliary tract reconstruction. The liver metastases were resected. Postoperative recovery was uneventful. Here, we present this case and review the literature focusing on management of PB.

The small bowel is a hollow organ involved in the transit and absorption of food. In relation to its anatomical location, a significant amount of this organ is exposed in whole or in part to ionizing radiation in external radiotherapy during abdominal or pelvic irradiation either for primary cancers or metastasis. The acute functional changes during external beam radiation are mainly leading to diarrhea, abdominal pain and bloating. The main late side effects of irradiation of the small intestine are chronic diarrhea, malabsorption with steatorrhea, abdominal spasms, intestinal obstruction, bleeding and fistulas. The architecture of the small intestine may be considered as parallel with a significant correlation between the irradiated volume of small bowel and the likelihood of acute toxicity, whatever the dose. The literature analysis recommends to consider the volume of small bowel receiving 15 Gy (threshold of 100 to 200 cm(3)) but also 30 and 50 Gy (thresholds of 35 to 300 cm(3), depending on the level of dose considered). Modern techniques of conformal radiotherapy with modulated intensity will probably have beneficial impact on small bowel toxicity.

Pancreatitis may be acute or chronic. Although both can be caused by similar aetiologies, they tend to follow distinct natural histories. Around 80% of acute pancreatitis (AP) diagnoses occur secondary to gallstone disease and alcohol misuse. AP is commonly associated with sudden onset of upper abdominal pain radiating to the back that is usually severe enough to warrant the patient seeking urgent medical attention. Onset of pain may be related to a recent alcohol binge or rich, fatty meal. The patient may appear unwell, be tachycardic and have exquisite tenderness in the upper abdomen. Overall, 10-25% of AP episodes are classified as severe, leading to an associated mortality rate of 7.5%. Disease severity is best predicted from a number of clinical scoring systems which can be applied at diagnosis in association with repeated clinical assessment, measurement of acute inflammatory markers, and CT. All patients with suspected AP should be referred urgently. Chronic pancreatitis (CP) follows continued, repetitive or sustained injury to the pancreas and 70% of diagnoses occur secondary to alcohol abuse. The characteristic presenting feature of CP is insidious progression of chronic, severe, upper abdominal pain, radiating to the back, caused by a combination of progressive pancreatic destruction, inflammation and duct obstruction. Signs and symptoms include weight loss and steatorrhoea and later on diabetes. CP patients may also present with recurrent episodes mimicking AP, both symptomatically and metabolically. Diagnosis of CP should be based on symptom profile, imaging and assessment of exocrine and endocrine pancreatic function. CT should be the first-line imaging investigation.

Cholecystocolic fistula is an uncommon biliary-enteric fistula with a variable clinical presentation that usually appears as a rare complication of gallstone disease. It can present with abdominal pain, nausea, weight loss, diarrhoea with or without associated steatorrhea, and dyspeptic symptoms. Rare cases have been reported with lower gastrointestinal haemorrhage and even with a gallstone ileous. The most useful techniques for diagnosis are CT, barium studies, and ERCP. We report a case of a cholecistocolic fistula in an elderly woman with multiple medical comorbidities that presented as lower gastrointestinal bleeding. She was explored with colonoscopy, abdominal CT and barium enema. She required a total of 4 units of whole blood and because of her comorbidities a decision was made not to proceed with invasive treatment. She had a good evolution and was asymptomatic two months later.

Chronic pancreatitis (CP) is progressive inflammatory process of the pancreas. Abdominal pain remains the most debilitating symptom affecting quality of life, apart from diabetes mellitus, steatorrhoea and weight loss. The treatment options have evolved over the past decades and are aimed to provide durable relief in pain with possible attempt to support or improve the failing endocrine and exocrine functions. Surgical treatment options have shown the potentials to provide superior long term results compared to the pharmacological and endoscopic modalities and are broadly divided in to drainage, resection and combination hybrid procedures. The choice is based on the morphology of the main pancreatic duct, presence of head mass and associated complication of CP. Knowing the basic nature of the disease, total pancreatectomy seems a curative option but not without significant morbidities. There is recent paradigm shift towards organ sparing surgical procedures with reasonable success. Despite recent advancement in the treatment modalities for CP the overall quality of life remains moderate which need further addressal.
