RESUMEN
BACKGROUND AND STUDY AIM: The study compared the efficacy of bowel cleansing using a low-volume mixed preparation (15âmg bisacodyl plus 2âL polyethylene glycol [PEG] solution) versus a standard high-volume preparation (4âL PEG) in patients with previous colorectal resection. PATIENTS AND METHODS: A total of 120 patients with prior colorectal resection for cancer undergoing surveillance colonoscopy were randomized to receive either a split-dose low-volume (nâ=â60) or high-volume (nâ=â60) preparation for bowel cleansing. The quality of bowel preparation, rated according to a modified Ottawa Bowel Preparation scale (mOBPS), represented the primary outcome measure. Tolerability, safety, and lesion detection rates were secondary outcomes. RESULTS: No significant difference was observed between the low-volume and high-volume preparations in achievement of adequate cleansing (i.âe. mOBPS ≤â4; low-volume vs. high-volume group, 85.0â% vs. 81.7â%, Pâ=â0.624). The low-volume preparation showed a higher success rate for cleansing of the right colon (Pâ=â0.025); better tolerability in terms of intake of the whole amount of the preparation (Pâ<â0.001) was also observed. According to the logistic regression analysis, the only predictors of unsuccessful cleansing were previous left colectomy (Pâ=â0.012) and a longer elapsed time since the intervention (Pâ=â0.034). Lesion detection rates were comparable between the groups. No serious adverse events were reported. CONCLUSION: A low-volume preparation is not inferior to a high-volume preparation for adequate bowel cleansing in patients with prior colorectal resection for cancer. If larger, multicenter, prospective studies confirm our findings, a low-volume preparation will represent a more tolerable option for such patients. TRIAL REGISTRATION NUMBER: ClinicalTrial.gov identifier NCT01887158.

Background and Aim: Double-balloon enteroscopy (DBE) is a well-established procedure for direct visualisation of the entire small bowel mucosa, and, in contrast with other imaging techniques, allows to perform biopsies and therapeutic interventions. The aim of this study was to evaluate the indications, diagnostic yield, therapeutic yield, and complications of DBE in a cohort of consecutive patients according to patients' age. Methods: We conducted a retrospective study of consecutive patients who underwent DBE in our endoscopy unit between January 2006 and December 2021. Results: A total of 387 consecutive patients who underwent 460 DBE procedures were included. Mean age of the patients was 63 years. The overall diagnostic yield was 67.6%; vascular lesions were the predominant endoscopic findings (31.5%), followed by polyps or neoplastic masses (17.6%). Older patients (≥65 years) showed statistically higher rates of clinically relevant findings than adult patients (18-65 years) (p = 0.001). Crohn's disease and polyps or neoplastic masses were more frequent in the younger group (p = 0.009 and p = 0.066, respectively), while vascular lesions and non-specific inflammation were the most common findings in the older group (p < 0.001 and p < 0.001, respectively). The therapeutic intervention rate was 31.7%. Rates of endoscopic treatment were significantly higher in the older group (p < 0.001). Total complications occurred in five procedures (1.1%). Conclusion: In clinical practice, DBE is an efficient diagnostic and therapeutic tool with a high safety profile, particularly in the elderly population.
RESUMEN
Herpes Zoster (HZ) presents a considerable public health burden in Italy among people aged ≥50 years. This study aimed to assess the clinical and economic impact of HZ vaccination in the 65 years of age (YOA) cohort in Italy, by comparing the new Adjuvanted Recombinant Zoster Vaccine (RZV) with the currently available Zoster Vaccine Live (ZVL). A static Markov model was developed to follow all 65 YOA subjects from the year of vaccination over their lifetime by comparing three different HZ vaccination strategies: no vaccination, vaccination with ZVL and vaccination with RZV. In the base-case scenario, three 65 YOA cohorts were assumed to be vaccinated within three years, with a vaccine coverage rate of 20%, 35% and 50% at Year 1, 2 and 3 respectively, as recommended by the National Immunization Plan. The three 65 YOA Italian cohorts accounted altogether for 2,290,340 individuals. Of these, it was assumed that 564,178 subjects could be vaccinated with either RZV or ZVL in three years. The vaccination with RZV could prevent an additional total number of 35,834 HZ and 8,131 postherpetic neuralgia (PHN) cases over ZVL, leading to additional total savings of 12.4 million for the national healthcare and social systems. The introduction of RZV can be expected to have higher impact on the burden of HZ disease in the 65 YOA cohort in Italy. The avoided HZ and PHN cases can lead to an associated reduction in economic burden to the healthcare and social systems.

BACKGROUND: The aim of our study was to test the long-term efficacy of Endo-SPONGE® therapy in a group of patients treated in our center with vacuum-assisted therapy because of anastomotic leakages after colorectal surgery. METHODS: Eleven patients [male: 6; mean age: 71 (range: 44-82) years] who had anastomotic leakage treated with Endo-SPONGE® placement were included in the study. Patient records were examined retrospectively. All patients with documented anastomotic leakage on abdominal computed tomography following an anterior resection of the rectum for rectal cancer underwent sigmoidoscopy to determine the extent of the anastomotic defect and the size of the presacral abscess. RESULTS: Ten of the 11 patients (90.9%) showed closure of the anastomotic leakage after a mean of 16 sponge changes. During follow up [mean: 29 (range: 6-64) months], we observed two cases of anastomotic stricture. Treatment failure was observed in one patient who presented an increased size of dehiscence after 23 sessions of endoscopic treatment, despite an initial good response. CONCLUSIONS: Our study substantially confirms previous conclusions and reaffirms that Endo-SPONGE® treatment for colorectal anastomotic leakages, performed in suitable patients, represents a successful and safe approach. The reduction in wound closure time, mild-to-moderate discomfort and possibly shorter hospitalization suggest that Endo-SPONGE® treatment can be a prominent therapeutic regimen with adequate patient acceptance.
RESUMEN
BACKGROUND: Capsule endoscopy is an established tool for the evaluation of obscure gastrointestinal bleeding but published literature is mostly limited to PillCam SB (Given Imaging, Israel). AIMS: The aims of this study were to determine the findings, the diagnostic yield and the rebleeding rate in a series of patients with overt or occult obscure gastrointestinal bleeding studied with MiroCam(Intromedic, Seoul, Korea) capsule endoscopy. METHODS: Data of 118 patients who underwent capsule endoscopy for overt or occult obscure gastrointestinal bleeding were prospectively collected between March 2009 and March 2011. RESULTS: Evaluation of the entire small bowel (completion rate) was achieved in 96% of cases. Relevant lesions occurred in 58% of patients. Angiodysplasias was the most common finding. Six patients (9% of the positive findings) had a non-small-bowel lesion detected by capsule. The yield of capsule endoscopy in the overt group was greater than in the occult group but without achieving a significant difference (61% vs. 54%, p>0.05). Rebleeding rate was lower in patients with a negative examination (6%) than in patients with a positive one (17%) (p=0.03). Capsule retention was registered in 3 of 118 patients (2.5%). CONCLUSIONS: MiroCam capsule endoscopy is a safe and effective tool for exploring small bowel with a high completion rate.

BACKGROUND: The 24-h ambulatory pH-metry with multichannel intraluminal impedance monitoring (24-h pH-metry+MII) allows the simultaneous assessment of chemical and physical properties of esophageal refluxes and the detection of its proximal migration. METHODS: Gastroesophageal reflux (GER) was investigated in obese symptomatic (obese gastroesophageal reflux disease, GERD) and asymptomatic (obese non-GERD) patients. The data were compared with those obtained from non-obese GERD patients and a control group. Thirty-five (20 non-GERD, 15 GERD) obese patients and 15 non-obese GERD were investigated with 24-h pH-metry+MII. Ten normal weight subjects with normal 24-h pH-metry+MII were used as control group. RESULTS: The percent time acid exposure was significantly higher in obese non-GERD than controls (p = 0.007). Acid reflux episodes were increased vs. controls in obese non-GERD (p = 0.005) and obese GERD (p = 0.034). Upright position showed a significant increase of reflux episodes in non-obese GERD (p = 0.034) and in obese non-GERD (p = 0.027) vs. controls. Recumbent position showed reflux episodes significantly increased vs. controls in obese non-GERD (p = 0.002), obese GERD (p = 0.021), and non-obese GERD (p = 0.033). In obese non-GERD, waist circumference (WC) correlated negatively with upright position episodes (r = -0.53; p = 0.043) and with proximal migration episodes, i.e., total (r = -0.60; p = 0.018), acid (r = -0.55; p = 0.033), and weakly acidic refluxes (r = -0.56; p = 0.031). CONCLUSIONS: Obese patients showed an increased number of refluxes with acid content. Refluxes with proximal extent were significantly higher in obese non-GERD than in controls and non-obese GERD patients. No difference was observed between the two obese patient groups. In asymptomatic obese patients, the WC correlated with proximal extent episodes.
