Impact of barium enema on acute diverticulitis recurrence: A retrospective cohort study of 349 patients.

Objective: Acute diverticulitis (AD) is becoming a health concern with its increasing incidence. One of the accepted theories of the possible causes of diverticular perforation is the impaction of fecal residuals into some diverticula. We aimed to evaluate whether barium impaction had a negative effect by promoting diverticular inflammation or rupture and thereby AD recurrence.

Factors Associated With Disease Recurrence in Breast Cancer Patients With Negative Sentinel Lymph Node Biopsy.

Introduction: The objective of our study was to assess recurrence after negative sentinel lymph node biopsy (SLNB) and to determine the risk factors related to local and distant recurrence in this group of patients.

Materials And Methods: We conducted a prospective observational study from 2006 to 2011. It included 607 patients with early-stage breast cancer and negative SLNB with a 5-year follow-up period.

Validation of the NASA-TLX Score in Ongoing Assessment of Mental Workload During a Laparoscopic Learning Curve in Bariatric Surgery.

Background: Fatigue and mental workload are directly associated with high-complexity tasks. In general, difficult tasks produce a higher mental workload, leaving little opportunity to deal with new/unexpected events and increasing the likelihood of performance errors. The laparoscopic Roux-en-Y gastric bypass (LRYGB) learning curve is considered to be one of the most difficult to complete in laparoscopic surgery.

Effectiveness of an absorbable fibrin sealant patch to reduce lymphoceles formation after axillary lymphadenectomy for breast cancer: a matched-pair analysis.

Background: This study evaluated the use of TachoSil as an adjunctive therapy for reducing axillary lymphocele formation.

Methods: Eighty-six patients diagnosed with breast cancer N+ and treated with axillary lymphadenectomy received a TachoSil patch in the axillary wound. Using a database of patients without placing a hemostatic patch, we applied a matched case-control in a 1-to-2 fashion.
