Perforated colonic diverticulitis usually requires surgical resection, which is associated with significant morbidity. Cohort studies have suggested that laparoscopic lavage may treat perforated less morbidity than resection procedures.To compare the outcomes from those for colon diverticulitis.Multicenter, randomized clinical superiority trial recruiting participants 21 centers in Sweden and Norway February 2010 to June 2014. The last patient follow-up was December 2014 final review...

Abstract Background Recent randomized trials demonstrated that laparoscopic lavage compared with resection for Hinchey III perforated diverticulitis was associated similar mortality, less stoma formation but a higher rate of early reintervention. The aim this study to compare 1-year outcomes in patients who participated the Scandinavian Diverticulitis (SCANDIV) trial. Methods Between February 2010 and June 2014, from 21 hospitals Norway Sweden presenting suspected were enrolled multicentre...

Perforated colonic diverticulitis usually requires surgical resection, with significant morbidity. Short-term results from randomized clinical trials have indicated that laparoscopic lavage is a feasible alternative to resection. However, it appears no long-term are available.To compare (5-year) outcomes of peritoneal and primary resection as treatments perforated purulent diverticulitis.This international multicenter trial was conducted in 21 hospitals Sweden Norway, which enrolled patients...

The creation of functional muscles/muscle tissue from human stem cells is a major goal skeletal muscle engineering. Mesenchymal (MSCs) fat/adipose (AT-MSCs), as well bone marrow (BM-MSCs) have been shown to bear myogenic potential, which makes them candidate for engineering applications. aim this study was analyse the differentiation potential AT-MSCs and BM-MSCs cultured in six different cell culture media containing mixtures growth factors. following were used our experiments: mesenchymal...

Giant Colonic Diverticulum (GCD) is a rare but potentially life-threatening complication of diverticular disease, defined as diverticulum larger than 4 cm, most commonly arising in the sigmoid colon. Its rarity could lead to diagnostic delays and mismanagement. A 64-year-old Caucasian female presented with persistent abdominal pain swelling. Examination revealed palpable mass left flank. computed tomography (CT) scan demonstrated an 11x10x14 cm air-filled cavity adjacent colon, initially...

Abstract Aim This study aimed to evaluate the implementation of nonantibiotic management acute uncomplicated diverticulitis at a large university hospital in Norway with regard failure, disease recurrence and complications. Method On 1 January 2013 we implemented new policy for without antibiotics. Antibiotic treatment was only provided case defined criteria.

Abstract Methods Recent randomized control trials (RCTs) have confirmed that antibiotics in acute uncomplicated diverticulitis (AUD) neither accelerate recovery nor prevent complications or recurrences. A retrospective cohort study was conducted, including all consecutive AUD patients hospitalized 2015- 2018 at Helsingborg Hospital (HH) and Skåne University (SUS), Sweden. HH had implemented a non-antibiotic treatment protocol 2014 while SUS not. Main outcomes were proportion of treated with...
