Previous studies have reported on the association between perioperative morbidity and diminished oncologic outcomes in patients undergoing resection for colorectal or pancreatic cancer. However, the effect of anastomotic leak (AL) on the survival of patients with gastric or esophageal cancer remains unclear. ⋯ AL following resection for gastric and esophageal cancer has a negative prognostic impact on long-term survival, independent from tumor stage and biology. Further investigation of the interactions between AL and the development of tumor recurrence as well as the establishment of standardized perioperative care protocols are necessary for the improvement of outcomes after gastric and esophageal resection.

Obese patients may present with metabolic abnormalities that impact liver regeneration. We sought to assess the impact of body mass index (BMI) on liver volume regeneration index (RI) and kinetic growth rate (KGR) among patients undergoing liver resection. ⋯ BMI did not impact liver regeneration during the first 2 months. In contrast, KGR per week between 2 and 7 months postoperatively was less among overweight and obese patients.

Three-dimensional (3D) printing is becoming increasingly important in medicine and especially in surgery. The aim of the present work was to identify the advantages and disadvantages of 3D printing applied in surgery. ⋯ The additional cost and the time needed to produce devices by current 3D technology still limit its widespread use in hospitals. The development of guidelines to improve the reporting of experience with 3D printing in surgery is highly desirable.

Umbilical and epigastric (umb/epi) hernia repairs are performed commonly in fertile female patients. Recent studies suggest mesh repair to be superior to suture repair; however, evidence is lacking concerning the optimal treatment of umb/epi hernias in female patients who might wish future pregnancies. The aim of this study was to compare the cumulative recurrence rate after mesh versus suture repair of umb/epi hernia in female patients subsequently becoming pregnant. ⋯ Contrary to findings in the general operative patient, mesh repair was not associated with a lesser risk of recurrence compared with suture repair for treatment of umb/epi hernia in female patients with subsequent pregnancy.
