Background In December 2019, a novel coronavirus was identified as the cause of many pneumonia cases in China and eventually declared as a pandemic as the virus spread globally. Few reports were published on the outcome of surgical procedures in diagnosed COVID-19 patients and even fewer on the surgical outcomes of asymptomatic undiagnosed COVID-19 surgical patients. We aimed to review all published data regarding surgical outcomes of preoperatively asymptomatic untested coronavirus disease 2019 (COVID-19) patients. Methods This report is a review on the perioperative period in COVID-19 patients who were preoperatively asymptomatic and not tested for COVID-19. Searches were conducted in PubMed April 4th, 2020. All publications, of any design, were considered for inclusion. Results Four reports were identified through our literature search, comprising 64 COVID-19 carriers, of them 51 were diagnosed only in the postoperative period. Synthesis of these reports, concerning the postoperative outcomes of patients diagnosed with COVID-19 during the perioperative period, suggested a 14/51 (27.5%) postoperative mortality rate and severe mostly pulmonic complications, as well as medical staff exposure and transmission. Conclusions COVID-19 may have potential hazardous implications on the perioperative course. Our review presents results of unacceptable mortality rate and a high rate of severe complications. These observations warrant further well-designed studies, yet we believe it is time for a global consideration of sampling all asymptomatic patients before surgical treatment.

Laparoscopic right hemicolectomy with intracorporeal anastomosis is associated with improved short- and long-term outcomes. The rates of postoperative complications requiring intervention and incisional hernias are decreased.

In octogenarians LC is safe and associated with acceptable morbidity and mortality. Therefore, it should be considered for this age group. The relatively high incidence of complicated gallstone disease in this age group may be decreased if surgery is offered to them at earlier stage of the disease, leading to further decrease in perioperative morbidity.

LA for benign adrenal disorders is a safe procedure that is associated with significantly lower morbidity, shorter ileus and hospitalization, reduced postoperative pain, and a faster return to normal activity than the open procedure.

Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessively inherited disorder consisting of the triad of oculocutaneous tyrosinase-positive albinism, prolonged bleeding time secondary to platelet storage pool defect and ceroid depositions within the reticuloendothelial system. Some patients also reportedly have gastrointestinal (GI) complications related to chronic granulomatous colitis, enterocolitis and extensive granulomatous perianal disease, the later previously unreported in the literature. These observations suggest that the GI complications of HPS are due to the development of classical Crohn's disease. The implications for disease pathogenesis and surgical management are discussed.

Objective: To describe the incidence of, the patterns of clinical presentation of, and the reasons for portomesenteric vein thrombosis among patients who underwent laparoscopic bariatric surgery.

Based on our findings, we recommend the routine use of preoperative imaging studies to exclude synchronous asymptomatic renal lesions in patients presenting with colorectal cancer.

The risk of recurrence after VHR in obese patients is high. Laparoscopic approach offers a better perioperative and recurrence outcome. We believe that change in those outcomes is possible through weight loss procedures, but may need further studies to be conducted in the form of prospective randomized trials.
