G-POEM in patients with gastroparesis - gambling for healing or bigger armamentarium ? A case series and review of the literature.

Approximately 30% of all affected patients suffering from gastroparesis do not respond to any available treatment modality. Gastric peroral endoscopic myotomiy (G-POEM, antropyloromyotomy) represents a new principle of therapy. In this single center study, G-POEM showed a high technical success rate with a very low procedural complication rate. However, the clinical response beyond a short-term post-interventional improvement did not succeed in a single patient. The heterogeneity of the clinical picture, which represents a spectrum of different pathophysiological, etiological and clinical characteristics, still requires a therapy tailored to the individual patient. G-POEM should be considered especially in patients with pylorus-dominant gastroparesis.

Calprotectin as Diagnostic Marker for Hepatic Encephalopathy and Spontaneous Bacterial Peritonitis in Cirrhosis.

BACKGROUND: Calprotectin is a well-established marker for intestinal inflammation, mainly in inflammatory bowel disease, and represents one of the most studied biomarkers in stool samples. METHODS: Apart from its important diagnostic role in inflammatory bowel disease, there are few studies showing that calprotectin can also be used as a diagnostic tool in patients suffering from hepatic encephalopathy (HE) and spontaneous bacterial peritonitis (SBP) in cirrhosis. RESULTS: Since calprotectin concentration in the human stool or in ascites is elevated at an early stage of inflammation, it might serve as an early screening tool for patients suffering from cirrhosis who are at risk to develop these conditions. As detection and monitoring of HE and SBP may be unclear and resource-intensive, identification of valid new markers of disease activity is necessary. In this review, we summarize the current knowledge of calprotectin as a diagnostic biomarker in cirrhosis, indicating that it is a highly promising diagnostic surrogate marker to screen for the presence of HE and SBP. CONCLUSIONS: To screen cirrhotic patients for SBP, calprotectin should be assessed in ascitic fluid while it should be measured in feces when screening for HE. However, the value of calprotectin in managing individual patients must be considered in the specific clinical context.

Disease phenotype rather than treatment strategy impacts the long-term quality of life in patients with diverticular disease.

PURPOSE: To identify the impact of the severity of diverticular disease on long-term quality of life. METHODS: Consecutive patients, hospitalized between October 2009 and November 2015 due to uncomplicated (UD) and complicated diverticulitis (CD) of the left colon, were analyzed. Patients undergoing emergent surgery for perforated disease were excluded. Primary endpoint was health-related quality of life (HrQol), measured by the Short Form 36 questionnaire (SF-36). Physical (PCS) and mental (MCS) compository scores were calculated from SF-36 subscales. To overcome bias, one-to-one propensity score matching and multivariable logistic regression analysis were performed. RESULTS: Two hundred eighty of the overall 392 patients (Male 138, Female 142; mean age 60.5 years, range 27-91) answered the SF-36 questionnaire. The median follow-up period was 37.8 months (range 15-85). After propensity score matching, each group consisted of 51 patients. Results of the SF-36 questionnaires showed a statistically significant difference, favoring patients with CD in 5 of 8 domains. Also, PCS (56.3 vs. 52.9, p = 0.13) and MCS (53.3 vs. 46.7, p = 0.005) were higher in patients treated for CD. By a multivariate analysis, complicated disease was independently associated with a better scoring on 6 out of 8 SF-36 subscales and on MCS. Treatment strategy (surgery or conservative) did not have any impact on SF-36 subscales, MCS, or PCS on multivariate analysis. CONCLUSION: In contrast to complicated disease, the uncomplicated diverticular disease is associated with an impaired long-term quality of life especially in domains composing mental health scores independently of chosen treatment strategy. STUDY REGISTRATION: The study is registered with the Research Registry at June 19, 2019. Research registry UIN: researchregistry4959 .

Patient perception and approval of faecal microbiota transplantation (FMT) as an alternative treatment option for obesity.

INTRODUCTION: Fecal microbiota transplantation (FMT) represents a treatment option for some diseases, e.g. recurring Clostridium difficile-associated colitis. However, there is also evidence that FMT can be effective in treating obesity. This pilot study established the approval and willingness of obese patients to undergo FMT. METHODS: We conducted a survey of adults with obesity using a questionnaire containing 21 both multiple choice and open questions was dispatched to a cohort of 101 persons with obesity. It included questions aiming at the process of FMT itself, donors as well as possible concerns. Additionally aspects of social background and disease activity were dealt with. RESULTS: The response rate amounted to 30.1% (n = 31). In our population, mean BMI was 40.5 kg/m2 while the vast majority already tried out treatment modalities to lose weight before. 25.8% of persons with obesity were aware of FMT. 62.1% were willing to undergo FMT if the donor was healthy and anonymous while only 6.9% clearly refused this option. Sixty preferred an anonymous donor or a person proposed by their doctor while colonoscopy was the preferred application by 76.7%. The absence of risks of the procedure (47.8%) formed the principal motivation while reduction of medication was considered as least important reason (in 26.1). Insufficient testing of the faeces concerning infections raised the most concerns (in 61.6%). CONCLUSION: For the majority of the persons with obesity surveyed FMT represents a treatment option. Approximately two thirds of the questionees would consider FMT as an alternative treatment option, even in spite of a satisfactory disease response to current standard therapies. Unsurprisingly there are concerns in regard to the transmission of possible infectious agents as well as to the hygieneic implementation of FMT itself.

[Endocrinology and interdisciplinary consultation in internal medicine : Illustrated using the example of polyglandular autoimmune syndrome]. / Endokrinologie als Schnittstelle in der interdisziplinären Inneren Medizin : Veranschaulichung anhand des polyglandulären Autoimmunsyndroms.

Polyglandular autoimmune syndromes encompass several endocrine and nonendocrine autoimmune disorders with variable onset and phenotype. Rheumatoid and gastroenterological symptoms in patients with autoimmune polyglandular syndromes are suggestive of additional rheumatoid gastrointestinal and hepatological autoimmune diseases. Autoimmune gastritis, celiac disease, autoimmune hepatitis, rheumatoid arthritis, Sjögren syndrome, and systemic Lupus erythematodus are of particular clinical relevance. In addition, unspecific rheumatoid and gastrointestinal attendant symptoms of the existing autoimmune endocrinopathy must be considered. Furthermore, certain disorders of polyglandular autoimmune syndromes, e. g., type 1 diabetes are frequently associated with particular gastrointestinal diseases such as small bowel bacterial overgrowth. An optimal patient-centered care of subjects with autoimmune diseases requires a comprehensive differential diagnostic work up and emphasizes the importance of an interdisciplinary cooperation.

Damage control strategy for the treatment of perforated diverticulitis with generalized peritonitis.

BACKGROUND: The best surgical strategy for the management of perforated diverticulitis with generalized peritonitis of the sigmoid colon is not clearly defined. The aim of this retrospective cohort study was to evaluate the value of a damage control strategy. METHODS: All patients who underwent emergency laparotomy for perforated diverticular disease of the sigmoid colon with generalized peritonitis between 2010 and 2015 were included. The damage control strategy (study group), included a two- stage procedure: limited resection of the diseased colonic segment, closure of proximal colon and distal stump, and application of an abdominal vacuum at the initial surgery followed by second-look laparotomy 24-48 h later At this point a choice was made between anastomosis and Hartmann's procedure. The control group consisted of patients receiving definitive reconstruction (anastomosis or Hartmann's procedure) at the initial operation. RESULTS: Thirty-seven patients were included in the study. Damage control strategy was applied in 19 patients and the control group consisted of 18 patients. Both groups were comparable in terms of demographics, severity of peritonitis, and comorbidities. The overall postoperative mortality was 11 % (n = 4). There were no statistically significant differences between both groups regarding postoperative morbidity and mortality; however, a significantly higher proportion of patients in the control group had a stoma after the initial hospital stay (83 vs. 47 %, p = 0.038). This difference was still significant after adjustment for sex, age, Mannheim Peritonitis Index, American Society of Anesthesiologists class and presence of septic shock at presentation. At the end of the follow-up period, 15 of 17 survivors in the study group and 13 of 16 survivors in the control group had their intestinal continuity restored (p = 0.66). CONCLUSIONS: Damage control strategy in patients with generalized peritonitis due to perforated diverticulitis leads to a significantly reduced stoma rate after the initial hospital stay without an increased risk of postoperative morbidity.

Clinical manifestations and treatment options in patients with cirrhosis and diabetes mellitus.

BACKGROUND: Diabetes is frequently diagnosed in patients with cirrhosis and represents an important risk factor for morbidity and mortality. Pharmacological therapy is limited due to hepatotoxicity and the risk of hypoglycemia. Investigations on medical practice in this patient population, frequency of diabetes-associated complications and the impact of quality of metabolic control are rare. AIMS AND METHODS: A retrospective analysis was performed to compare the effects of hypoglycemic treatment, the achieved glycemic control under therapy, the prevalence of typical cirrhosis-related or microangiopathic complications, and cardiovascular comorbidities between a group of diabetic patients with cirrhosis (n = 87) and a nondiabetic cirrhotic population (n = 198). RESULTS: The prevalence of diabetes in our cohort was 30.5%. Of all diabetic patients, 39.1% received therapy which might potentially result in serious side effects in patients with end-stage liver disease. The rate of ongoing alcohol abuse (28.7%) and noncompliance under medication (41.4%) was high. Only 28.7% of all diabetic subjects showed satisfactory (as defined by HbA1c ≤ 6.5%) glycemic control under therapy. Patients achieving satisfactory control experienced a lower rate of certain cirrhosis-related complications such as hepatic encephalopathy (HE) and hepatocellular carcinoma (HCC), arterial hypertension, and hypercholesterolemia. HE was significantly more frequent in diabetic than nondiabetic cirrhotic patients.

The effect of osmolarity and caloric load on small bowel motility.

BACKGROUND: Although there is profound knowledge about cyclic fasting motility, the postprandial intestinal motor response is not well investigated. It is intriguing to speculate that nutrient composition alters small bowel motility significantly and, in a clinical setting, may account for adverse gastrointestinal symptoms in enteral nutrition (EN). We aimed to assess the impact of different caloric loads and osmolarities of EN on human jejunal motility. METHODS: Sixteen healthy subjects underwent a series of duodenal infusions of EN solutions, either with iso-osmolar solution with different caloric loads (1.32, 2.64, or 3.96 kcal min(-1)), or with solutions of different osmolarities with constant caloric loads (300, 600, or 1200 mosmol). Jejunal solid-state manometry was analyzed over 90 min both visually and using dedicated computer software. KEY RESULTS: All tested nutrient solutions were able to trigger conversion to a postprandial jejunal motility pattern after a mean lag phase of 9.4 + 2.3 min (P = NS between different nutrient solutions). Different caloric loads did not result in significant differences in small bowel motility. However, increasing osmolarities caused a significant inhibition of contractile and propagative activity. CONCLUSIONS & INFERENCES: Small bowel motility under duodenal infusion of nutrient solutions is not influenced by caloric load in a physiological range, whereas high osmolarities inhibit small bowel motility.

[Management of impacted foreign bodies in the upper gastrointestinal tract in adult patients - results of a retrospective case series]. / Management von impaktierten Fremdkörpern im oberen Gastrointestinaltrakt bei erwachsenen Patienten - Ergebnisse einer retrospektiven Fallserie.

INTRODUCTION: Impaction of foreign bodies in the upper gastrointestinal tract represents a rare endoscopic emergency regarding the danger of organic lesions. Therefore, the therapeutic strategy, rational postinterventional monitoring and potential consequences for the course in the future are often not clear. METHODS: Out of all oesophagogastroduodenoscopies performed between 2008 and 2010 (n = 10,830), the endoscopies due to bolus impaction were analysed retrospectively concerning endoscopic findings, course of intervention and causative predisposing factors using descriptive statistics. RESULTS: In the study period, endoscopy was performed in 45 different patients 49 times when foreign body impaction was suspected. In 38 cases (77.6%) a foreign body could be detected by endoscopy, most frequently a meat bolus (65.8%), followed by dental prostheses and tablets. Endoscopic removal could be successfully performed in 97.4%. An operation was necessary in only one patient. A macroscopically unremarkable upper gastrointestinal tract without any predisposing conditions for foreign body impaction could be detected in 33.3%. In one case eosinophilic oesophagitis could be diagnosed histologically. The foreign body was pushed into the stomach by the "push technique" in 54.1%. The foreign body removal was performed as an ambulant intervention in 63.2%. DISCUSSION: In the majority of cases, impacted foreign bodies of the upper gastrointestinal tract could be removed safely by endoscopy, e.g., using the "push technique". However, the therapeutic strategy should be individually adjusted based on the consistancy of the foreign body. If no predisposing conditions can be found, histological diagnosis should be performed to detect potential eosinophilic oesophagitis early enough.

[Frequency of cardiac arrhythmia in patients with liver cirrhoses and evaluation of associated factors]. / Häufigkeit von Herzrhythmusstörungen bei Patienten mit Leberzirrhose sowie Evaluierung assoziierter Faktoren.

INTRODUCTION: Studies analysing the frequency of rhythm disorders in patients with cirrhosis are rare. Nevertheless, factors triggering rhythm disorders occur frequently in cirrhosis. Therefore, a retrospective case control study was performed investigating the frequency of cardiac arrhythmia in a population of patients with cirrhosis while evaluating several associated factors. METHODS: The files of patients with cirrhosis (n  =  293) in the period 2004 - 2008 were analysed retrospectively regarding cardiac arrhythmia. The frequency of cardiac arrhythmia in the presence of relevant risk factors was analysed using χ ²tests and logistic regression models. RESULTS: 61.1  % of all patients were male (mean age 61.7 years) and 38.9  % female (mean age 62.8 years). The severity of cirrhosis according to the Child-Pugh score (CP) was as follows: CP A 43.3  %, CP B 32.8  % and CP C 23.9  %. Altogether, rhythm disorders were diagnosed in 16.4  % (48/293) of the study population, most frequently atrial fibrillation (68.8  %) and atrial flutter (6.7  %). An advanced age and comorbidities such as arteriosclerotic diseases, hypercholesterinemia (p  <  0.001, each) and diabetes mellitus (p  =  0.013) correlated significantly with the frequency of rhythm disorders which occurred more often in males than in females (p  = 0.066). Ongoing alcohol abuse, the severity of cirrhosis and arterial hypertension were not associated significantly with the onset of rhythm disorders. 84.4  % of all patients with cardiac arrhythmia were treated by diuretics. Decreased (<  3.5 mmol/L) and elevated (>  5 mmol/L) potassium values were observed in 60.6  % of the study collective. Rhythm disorders were more often observed in patients with hyperkalemia (especially atrioventricular block, p  < 0.01). CONCLUSION: Compared to the average population, the prevalence of atrial fibrillation was increased in our cirrhotic cohort. The occurrence of rhythm disorders was significantly associated with arteriosclerotic diseases, hypercholesterinaemia and diabetes mellitus. Additionally, cardiac arrhythmia must be considered under diuretic therapy and in the presence of electrolyte disturbances.

Accuracy of anorectal manometry in patients with fecal incontinence.

BACKGROUND/AIM: Patients with fecal incontinence (FI) have lower anal resting (MRP) and squeeze (MSP) pressure and an impaired sensitivity compared to healthy people. However, whether anorectal manometry (ARM) can separate precisely between health and disease is discussed controversially. The aim was to evaluate the accuracy of ARM in a huge cohort of patients and controls. METHODS: ARM was obtained in 144 controls and in 559 FI patients. MRP, MSP, and balloon volume at first perception (BVP) and urge sensation (BVU) were determined. Receiver operating curve analysis was used to determine optimal cut-offs and sensitivity, specificity and accuracy calculated. RESULTS: FI patients showed lower MRP, MSP, BVU (p < 0.001) and a higher BVP (p = 0.007). Deterioration of the ARM parameter increased with FI severity. ARM demonstrated an excellent sensitivity (91.4%) and accuracy (85.8%), but only a moderate specificity (62.5%). The sensitivity of ARM rose with FI severity. The pressure data showed higher sensitivity and accuracy than the sensory data despite comparable specificity. CONCLUSIONS: Sensitivity and accuracy of single ARM parameters is only moderate for the pressure data and poor for the sensory data. In contrast, ARM demonstrated an excellent sensitivity, a moderate specificity, and a convincing accuracy justifying its use in clinical routine.

Comparison of small-bowel motility of the human jejunum and ileum.

BACKGROUND: Knowledge about human cyclic fasting motility (MMC) and the postprandial response is mostly based on manometric findings in the upper small intestine. Hardly any data exist on human ileal motility, as the acquisition of data has been limited by methodological concerns. The aim was to study human jejunal and ileal motility in an optimized manometric setting. METHODS: Solid-state 24-h-manometry was performed in the jejunum and ileum of healthy individuals, applying a strict protocol for fasting, resting, and the consumption of a standardized meal. Both visual qualitative and validated computerized quantitative contraction and propagation analysis were performed. KEY RESULTS: MMC occurs in similar frequency in the jejunum and ileum, but it was significantly shorter in the jejunum at night. By many characteristics, ileal motility was less intense and propagative than jejunal: less migrating clustered contractions, and slower propagation velocity and shorter distance in phases II and III, and postprandially - possibly slowing and enhancing nutrient absorption. Prolonged propagated contractions in some individuals were identified as a unique ileal propulsive pattern. Postprandially, an abrupt conversion to a digestive motility pattern occurs simultaneously independent of the region. CONCLUSIONS & INFERENCES: We found similar basic phenomena of fasting and postprandial motility in the jejunum and ileum of healthy humans. However, different calibration of propagative and contractile activity and special motor events in the ileum may account for a different physiological role in digestion. Future studies of small-bowel motility in healthy and diseased subjects focusing on segmental differences of proximal and distal intestine may be rewarded.
