Analysis of patients attitude to undergo urgent endoscopic procedures during COVID-19 outbreak in Italy.

We conducted a survey to investigate to what extent the fear of COVID-19 has influenced the patients decision to undergo or to cancel endoscopic procedures. We collected data from 847 patients from 13 centres. The main indication for endoscopy was anemia, followed by pain and unexplained weight loss. The percentage of not presenters progressively increased throughout the three weeks of study, from 15.1% at the beginning to 48.2% at the end. 37 (34.2%) upper GI endoscopies and 112 (56.3 %) colonoscopies showed an organic cause explaining the symptoms presented by the patients, respectively; 5 cases of gastric cancer (4.6%) and 16 cases of colorectal cancer (CRC) (6.0%), respectively, were detected; during the second week the percentage of organic diseases found at upper endoscopy was 19 (33.3%) with 5 cancer (8.7%), and 61 (49.1% ) at colonoscopy, with 2 CRC (1.6%); finally, during the third week the corresponding figures were 19 (48.7%) for upper GI examinations, with 3 gastric cancers (7.7%), and 43 (60.5%) with 4 (6.5%) CRC cases found.We conclude that patients weighted the fear of having a clinically relevant disease with the fear of becoming infected by coronavirus, and a relevant percentage of them (29.4%) decided not to attend the endoscopy suites at the scheduled date.

The 2018 ISDE achalasia guidelines.

Achalasia is a relatively rare primary motor esophageal disorder, characterized by absence of relaxations of the lower esophageal sphincter and of peristalsis along the esophageal body. As a result, patients typically present with dysphagia, regurgitation and occasionally chest pain, pulmonary complication and malnutrition. New diagnostic methodologies and therapeutic techniques have been recently added to the armamentarium for treating achalasia. With the aim to offer clinicians and patients an up-to-date framework for making informed decisions on the management of this disease, the International Society for Diseases of the Esophagus Guidelines proposed and endorsed the Esophageal Achalasia Guidelines (I-GOAL). The guidelines were prepared according the Appraisal of Guidelines for Research and Evaluation (AGREE-REX) tool, accredited for guideline production by NICE UK. A systematic literature search was performed and the quality of evidence and the strength of recommendations were graded according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Given the relative rarity of this disease and the paucity of high-level evidence in the literature, this process was integrated with a three-step process of anonymous voting on each statement (DELPHI). Only statements with an approval rate >80% were accepted in the guidelines. Fifty-one experts from 11 countries and 3 representatives from patient support associations participated to the preparations of the guidelines. These guidelines deal specifically with the following achalasia issues: Diagnostic workup, Definition of the disease, Severity of presentation, Medical treatment, Botulinum Toxin injection, Pneumatic dilatation, POEM, Other endoscopic treatments, Laparoscopic myotomy, Definition of recurrence, Follow up and risk of cancer, Management of end stage achalasia, Treatment options for failure, Achalasia in children, Achalasia secondary to Chagas' disease.

Role of symptoms, trend of liver tests, and endotherapy in management of post-cholecystectomy biliary leak.

AIM: Biliary leaks are widely reported complications of cholecystectomy, but standard management remains undecided. The objective of our study was to report the role of symptoms, biochemical tests, and ERCP in patients with a leak. MATERIALS AND METHODS: Twenty-one patients (8 M, 26-77 years) with suspected post-cholecystectomy biliary leak were retrospectively studied. Symptoms and liver tests (LTs) after surgery were monitored. Trends of LTs were considered positive if increases at >48 h were seen. ERCP was performed in all patients. Findings at endoscopy and treatments were reported. Outcome results were obtained for all patients. RESULTS: Seventeen of 21 patients had persistent biliary leak at ERCP, because of direct injury (n = 10), accessory duct (n = 4), or cystic duct stump (n = 3). Eleven of 17 patients (six without symptoms), had distal obstruction because of surgical injury (n = 8), stone (n = 2), or cholangiocarcinoma (n = 1) and underwent stenting (n = 4), naso-biliary drainage, NBD (n = 3), or surgery (n = 4). Among the six patients without obstruction (four without symptoms), stenting was performed in two and NBD in four. The four patients without apparent leak underwent NBD. Impairment of LTs was present in ten out of eleven (91%) patients with obstruction versus six of ten (60%) without obstruction. No complications occurred after ERCP. During a median follow-up of 33 months (cholangiocarcinoma excluded) all but one remained asymptomatic. CONCLUSIONS: Symptoms and trend of LTs were not predictive of biliary obstruction in patients with a leak after cholecystectomy. Both endotherapy and surgery had favorable outcomes.

ERCP and short-term stent-trial in patients with anastomotic biliary stricture following liver transplantation.

BACKGROUND: Anastomotic biliary stricture represents one of the possible factors leading to liver dysfunction after transplantation. PURPOSE: Our aims were to evaluate the role of endoscopic retrograde cholangio-pancreatography and a short-term stenting (stent-trial) in assessment of the clinical relevance of the biliary stricture. MATERIALS AND METHODS: Thirty transplanted patients for HCV (n=17) or non-HCV (n=13)-related cirrhosis (27M, median age 53 yr, range 24-67 yr) who developed persistently abnormal liver function tests and presented with an anastomotic biliary stricture suggested by non-invasive cholangiography, underwent endoscopic retrograde cholangio-pancreatography. If the stricture was confirmed, dilation was performed and a plastic stent was placed. Clinical and biochemical evaluation was done one and two months later. Resolution of symptoms and normalization or > 50% reduction of at least one liver function test were needed to consider the stricture as clinically relevant. Patients were followed up for a median of 19 months. RESULTS: Endoscopic retrograde cholangio-pancreatography was successful in 29 patients and confirmed the anastomotic biliary stricture in 19 (66%); 14 patients underwent endoscopic dilation and stenting and five patients underwent surgery. The stent-trial suggested the stricture to be clinically relevant in 7 of 14 patients, confirmed by prolonged stenting and follow-up. A trend towards a higher likelihood of a clinically relevant stricture was observed in HCV-negative compared to HCV-positive patients (5 of 7, 71% vs 2 of 7, 29% , respectively; p=0.1). CONCLUSIONS: Our data suggest that endoscopic retrograde cholangio-pancreatography is a valuable tool to evaluate the clinical relevance of an anastomotic stricture, when coupled with a short-term stent-trial.

Impact of referral for gastro-oesophageal reflux disease on the workload of an academic Gastroenterology Unit.

BACKGROUND: Gastro-oesophageal reflux disease is known to be a frequent cause of patients' referral to hospital gastroenterologists. AIM: To increase knowledge on referral for reflux disease, in an Italian academic setting. PATIENTS AND METHODS: The impact of gastro-oesophageal reflux disease on 1 year's workload, comprising upper endoscopy, outpatients' consultations in the general clinic, oesophageal pH monitoring and oesophageal manometry was retrospectively assessed. Appropriateness of oesophageal pH monitoring and oesophageal manometry was also evaluated. RESULTS: Endoscopy: Out of 2269 upper endoscopies reflux symptoms comprised 16.9% (n=386) of referrals; 19.1% only of these 386 patients had erosive oesophagitis at endoscopy and none had oesophagogastric malignancies (68% of the patients were >45 years). Consultations: Thirty-three percent out of 553 patients were referred for reflux symptoms. Upper endoscopy had already been performed before consultation in 64% of them. pH monitoring and oesophageal manometry: Two hundred and sixteen oesophageal pH monitorings and 160 oesophageal manometries were performed and 29% and 28%, respectively, were inappropriate, being performed in the diagnostic work-up of patients with typical reflux symptoms. CONCLUSIONS: At an academic Gastroenterology Unit, (a) gastro-oesophageal reflux disease is a frequent referral for upper endoscopy and consultations, (b) prevalence of oesophagitis is low, (c) consultation is preceded by endoscopy in the majority of patients and (d) oesophageal pH monitoring and oesophageal manometry are often inappropriately used.

Gastric involvement in a patient with secondary syphilis.

A 30-year-old man was referred because of a short lasting history of severe epigastric pain and early satiety, with remarkable weight loss. Physical examination was fully consistent with secondary syphilis and upper GI tract endoscopy revealed multiple gastric mucopurulent erosions and several nodular lesions ranging from 2 to 3 cm in diameter, with central crater, abruptly ending at the pyloric level. Appropriate antibiotic treatment obtained a dramatic improvement and complete reversal of cutaneous and gastric lesions.

Endoscopic treatment of gastroesophageal reflux disease.

Gastroesophageal reflux disease is a common chronic disorder which has a severe effect on the patient's quality of life. In view of the high cost of medical therapy and the limitations of surgery, a variety of endoscopic techniques have been developed for the treatment of this condition, and these have shown apparently encouraging results, at least in the short term. However, promising results have been obtained in only around two-thirds of patients over a short-term follow-up period of about 6 months. Moreover, several inconsistencies have emerged between the efficacy of this form of treatment in improving symptoms and quality of life and a lack of improvement of objective parameters, such as lower esophageal sphincter pressure and esophageal acid exposure. The authors strongly endorse the need for comprehensive evaluation of clinical evidence on this topic. After an extensive evaluation of existing literature, we suggest that controlled studies are urgently needed in order to clarify the potential of endoscopic therapy, either in terms of cost-effectiveness or in comparison with standard therapy. Meanwhile, with regard to current practice, the use of endoscopic treatment should be limited to clinical trials, which should incorporate the provision of comprehensive and unbiased information to study patients.

Spontaneous perforation of an oesophageal diverticulum in achalasia.

Spontaneous perforation of the oesophagus is a rare occurrence that is usually due to vomiting and is seldom associated with an oesophageal lesion. We report a case of the spontaneous perforation of a large oesophageal diverticulum not preceded by any precipitating event in a 75-year-old male who was not known to have achalasia. The diverticulum was repaired by emergency surgery. Achalasia was later diagnosed and successfully treated with botulin toxin injection. Surgery decision-making and the treatment of achalasia are discussed.

Gastric emptying of oil and aqueous meal components in pancreatic insufficiency: effects of posture and on appetite.

The aims of this study were to evaluate the effects of posture on gastric emptying, intragastric distribution, and satiation after a meal containing oil and aqueous phases in patients with exocrine pancreatic insufficiency. Five patients with cystic fibrosis (CF) consumed 60 ml 99mTc-labeled (V)-thiocyanate olive oil and 290 ml 113mIn-labeled diethylenetriaminepentaacetic acid soup while sitting and while lying in the left lateral decubitus position. Hunger and fullness before and after the meal were recorded. Results were compared with those obtained in 11 normal volunteers. In both postures emptying of oil was faster (P < 0.01) in CF patients. Emptying of the aqueous phase was faster (P < 0.01) in CF patients in the decubitus position. In normal subjects there was no overall difference in emptying of oil between the two postures, whereas emptying of the aqueous phase was delayed (P < 0.01) in the decubitus position. In CF patients emptying of oil was faster (P < 0.01) in the decubitus position, and emptying of the aqueous phase was only slightly faster (P < 0.05) in the sitting position. For both postures there was greater retention (P < 0.05) of oil in the proximal stomach in normal subjects than CF patients. Hunger decreased (P < 0.05) after the meal in the control subjects, but there was no change in CF patients. These results indicate that in CF patients with pancreatic exocrine insufficiency 1) gastric emptying of nonhomogenized fat is faster than normal, 2) gravity affects gastric emptying of oil, and 3) effects of a fatty meal on hunger are reduced.

Giant fibrovascular polyp of the oesophagus: report of a case and effects on oesophageal function.

A 40 year old man with dysphagia and a giant fibrovascular polyp of the oesophagus is reported. The patient was followed for two years before removal of the polyp. During this period the tumour markedly increased in size and the oesophagus reached a maximum diameter of 5.9 cm. In presence of the polyp the body of the oesophagus had no pressure activity after swallows and a 22 hour intraoesophageal pH record showed pH greater than 7 for 31.4% of the time and never pH less than 4. After excision of the tumour the oesophagus regained normal size and peristalsis. Intraoesophageal pH greater than 7 and less than 4 were recorded for 1.6% and 16.1% of the time respectively. Dysmotility was probably a contributing factor to the genesis of dysphagia induced by the giant fibrovascular polyp. Prolonged alkalinisation of intraoesophageal pH conceivably reflected altered oesophageal clearing of alkaline salivary and/or oesophageal secretions.

Empiric treatment of infections in granulocytopenic patients with acute leukemia: a study on amikacin-carbenicillin-cotrimoxazole.

The amikacin-carbenicillin-cotrimoxazole combination was used as an empiric treatment for febrile episodes in patients with acute leukemia and severe granulocytopenia. The choice of drugs was based on the finding in our institute that the majority of infections are caused by gram-negative rods, particularly Pseudomonas, with high percentage of strains resistant to gentamycin and tobramycin. Granulocyte transfusions were given to the patients who did not show satisfactory clinical improvement 48 h after start of antibiotic therapy. There were cures in 84.6% of the febrile episodes treated with this antibiotic combination, including five of eight episodes of microbiologically confirmed bacteremia. Survival after 21 days of antibiotic therapy amounted to 89.1%. Renal toxicity occurred in 10.9% of the episodes treated. The prompt use of this antibiotic combination seems to be a safe and efficacious therapeutic tool for treating these high-risk patients.
