The objectives of this study were to describe lung computed tomography findings of patients with COVID-19 diagnosed by real-time reverse transcription polymerase chain reaction test, investigate whether the findings differ regarding age and gender, and evaluate the diagnostic performance of chest computed tomography based on the duration of symptoms at the time of presentation to the hospital.

From March 11 to May 11, 2020, 1271 consecutive patients (733 males and 538 females) were included in this retrospective, cross-sectional study. Based on age, patients were divided into five separate subgroups. Then based on the duration of symptoms, patients were divided into five separate phases. The presence of lung lesion(s) and their characteristics, distribution patterns, and the presence of concomitant pleural thickening/effusion and other findings (malignancy, metastasis, chronic obstructive pulmonary disease, interstitial lung disease, bronchiectasis, bronchiectasis, cardiomegaly, pericardial effusion) were evaluated by five radiologists independently.

The "normal lung computed tomography finding" was the most common chest CT finding (37%), followed by ground-glass opacity (31%). Regardless of the shape of the lesion, the distribution features were significant (peripheral, subpleural, and lower lobe distribution) (p<0.05). The presence of pleural thickening posteriorly and adjacent to the lesion was statistically different in groups 1-3 (p<0.05). Other concomitant pathologies, except pulmonary congestion, did not suppress the typical findings of COVID-19.

Chest computed tomography findings were mostly normal in the early phase (P1). Therefore, it may be appropriate to perform the first computed tomography screening of COVID-19 after 6 days to decrease the radiation exposure.

While investigations into the spread of this new variant are ongoing, the first cases have been detected in Switzerland. Important questions have been raised (1) Will the PCR assays commonly used to detect SARS-CoV-2 still work for the Omicron variant? (2) Can specific PCR features, e.g. S-gene dropout, be used to identify potential Omicron samples? In this minireview we provide current knowledge on the Omicron variant and guidance on its PCR validation.

In many patients, the diagnosis of Crohn's disease (CD) is made during surgery for appendicitis in urgent settings. Intraoperative diagnosis can be challenging in certain cases, especially for less experienced surgeons.

Review of the literature searching for scientific evidence that can guide surgeons through optimal management of ileocecal CD found incidentally in surgery for acute appendicitis (AA).

Included studies were identified by electronic search in the PubMed database according to the Preferred Items of Reports for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. selleck inhibitor The quality and bias assessments were performed by Methodological Index for Non-Randomized Studies (MINORS) criteria for non-randomized studies.

A total of 313 studies were initially identified, six of which were selected (all retrospective) for qualitative assessment (two studies were comparative and four only descriptive case series). Four studies identified a high rate of complications when appendectomy or ileocolectomy wnfirm these claims.

Endometriosis is a common disease in reproductive-age women and it is estimated to occur in up to 50% of those with infertility. Intestinal involvement is reported in up to a third of the cases. This condition is related to chronic pain and loss of quality of life, resulting in emotional, social and economic costs. Treatment consists of hormonal block and surgical resection, with variable side effects and efficacy. The best choice for surgical treatment for rectal endometriosis is a matter of discussion regarding the indication and the best technique to be employed.

To summarize data on indications, results and complications of surgical techniques for the treatment of rectal endometriosis.

This comprehensive systematic review is a compilation of the available literature and discussion, carried out by a team with experience in the surgical treatment of intestinal endometriosis. Data regarding indications, results and complications of conservative and radical techniques for the surgical treatment of rectaisciplinary team.

Inflammatory bowel diseases (IBD), comprising Crohn's disease and ulcerative colitis, are chronic inflammatory diseases of the gastrointestinal tract that often have their onset among adolescents and young adults (AYA). IBD are characterized by episodes of active disease interspersed with periods of remission, and its activity is inversely correlated with health-related quality of life (HRQL).

This study aimed to determine whether AYA in remission or with low IBD activity would exhibit HRQL similar to that of age-matched healthy individuals, and whether demographic and disease factors could affect HRQL using a 'patient-reported outcome' instrument.

This study enrolled only AYA with IBD, with low activity. This research included five multidisciplinary clinics of two academic hospitals Paediatric Gastroenterology, Gastroenterology, Coloproctology, Paediatric Rheumatology and Adolescent divisions, São Paulo, Brazil. A total of 59 AYA with IBD (age, 13-25 years) and 60 healthy AYA (age, 13-25 years) completIBD patients.

AYA with low IBD activity reported poor HRQL in school/work and general health perception domains, which highlights a disability criterion in this vulnerable population.

Traditionally peptic ulcer disease was the most common cause of upper gastrointestinal (UGI) bleed but with the changing epidemiology; other etiologies of UGI bleed are emerging. Many scores have been described for predicting outcomes and the need for intervention in UGI bleed but prospective comparison among them is scarce.

This study was planned to determine the etiological pattern of UGI bleed and to compare Glasgow Blatchford score, Pre-Endoscopy Rockall score, AIMS65, and Modified Early Warning Score (MEWS) as predictors of outcome.

In this prospective cohort study 268 patients of UGI bleed were enrolled and followed up for 8 weeks. Glasgow Blatchford score, Endoscopy Rockall score, AIMS65, and MEWS were calculated for each patient, and the area under the receiver operating characteristic (AUC-ROC) curve for each score was compared.

The most common etiology for UGI bleed were gastroesophageal varices 150 (63.55%) followed by peptic ulcer disease 29 (12.28%) and mucosal erosive disease 27 (11.44%). Total 38 (15.26%) patients had re-bleed and 71 (28.5%) patients died. Overall, 126 (47%) patients required blood component transfusion, 25 (9.3%) patients required mechanical ventilation and 2 (0.74%) patients required surgical intervention. Glasgow Blatchford score was the best in predicting the need for transfusion (cut off - 10, AUC-ROC= 0.678). Whereas AIMS65 with a score of ≥2 was best in predicting re-bleed (AUC-ROC=0.626) and mortality (AUC-ROC=0.725).

Gastrointestinal bleed was most commonly of variceal origin at our tertiary referral center in Northern India. AIMS65 was the best & simplest score with a score of ≥2 for predicting re-bleed and mortality.

There are two phenotypes of the disease erosive GERD, when erosions are identified by upper digestive endoscopy, and non-erosive GERD, when the esophageal mucosa presents a normal endoscopic aspect. Relevant clinical findings are usually absent in the physical examination, but it should be highlighted that obesity is an important aggravating factor of reflux. The treatment is established based on clinical findings and, according to the clinical situation, on complementary exams such as upper digestive endoscopy. In dubious cases where a precise diagnosis is required, the indicated test is esophageal pHmetry or impedance-pHmetry. Clinical treatment is divided into behavioral/dietary measures and pharmacological measures. Most patients benefit from clinical treatment, but surgical treatment may be indicated in the presence of a larger hiatal hernia and complications of the disease.

Esophageal stenosis (ES) in children is a fixed intrinsic narrowing of the esophagus due to numerous aetiologies.

This study aimed to determine the clinical and nutritional impacts of endoscopic balloon dilation (EBD) in Iranian children with an esophageal stricture.

This retrospective study, pediatric patients (aged <18 years) who underwent EBD for esophageal stricture from April 2015 until March 2020 in Abuzar Children's Hospital (Ahvaz, Iran) were enrolled in the study. Outcome parameters were the frequency of dilations, nutritional status, complications, and clinical success rates. EBD was used in children with radiologic evidence of esophageal stenosis. The nutritional status was evaluated by weight-for-age (z-score). Clinical success was considered as no necessity of EBD for a minimum of one year and/or increasing interval among dilation and the frequency of EBD was less than four times per year.

A total of 53 cases (mean age, 4.72±3.38 years) were enrolled. There were 25 (47.2%) females and 28 (52.8%) males. During follow-up, a total of 331 EBD sessions were performed, with an average of 6.24 sessions per patient. There was one case of perforation and one case of mediastinitis, while there was no other complication or mortality. The clinical success rate of EBD therapy was 62.3% (33/53). The mean standard deviation z-score weight-for-age of patients before and after endoscopic dilation was 2.78 (2.41) and 1.18 (1.87), respectively. The t-test showed a significant difference between the weights-for-age (z-score) before and after endoscopic dilation. The majority of the patients had raised weight-for-age (z-score) after EBD treatment.

EBD attained a good clinical success rate and nutritional improvement in children with an esophageal stricture.

Robotic surgery has gained growing acceptance in recent years, expanding to liver resection.

The aim of this paper is to report the experience with our first fifty robotic liver resections.

This was a single-cohort, retrospective study. From May 2018 to December 2020, 50 consecutive patients underwent robotic liver resection in a single center. All patients with indication for minimally invasive liver resection underwent robotic hepatectomy. The indication for the use of minimally invasive technique followed practical guidelines based on the second international laparoscopic liver consensus conference.

The proportion of robotic liver resection was 58.8% of all liver resections. Thirty women and 20 men with median age of 61 years underwent robotic liver resection. Forty-two patients were operated on for malignant diseases. Major liver resection was performed in 16 (32%) patients. Intrahepatic Glissonian approach was used in 28 patients for anatomical resection. In sixteen patients, the robotic liver resection was a redo hepatectomy.
