Minimally invasive surgery was performed in &gt;90% of cases, with a conversion rate to laparotomy of 1%. The mean surgery time was 109.37\u2009\u00b1\u200937.67\u2009min. Estimated blood loss was minimal (93.74\u2009\u00b1\u200993.13\u2009mL), with a mean hemoglobin drop of 1.32\u2009\u00b1\u20091.01\u2009g\/dL. Transfusions were required in only three patients (2%). Postoperative hospital stays exceeded 2\u2009days in 51% of cases. Lymph node metastasis was observed in just one case (1%). Adverse events included 52 grade 1 and 2 grade 2 events (e.g., headache, paresthesia).
