Objective: Laparoscopic sleeve gastrectomy (LSG) was considered mainly as a restrictive procedure due to anatomic alterations in the upper gastrointestinal tract. Additionally, due to neurohormonal alterations, LSG modifies the gastrointestinal motility, which controls appetite and feeling of satiety.

Aim: The aim of the study was to review the impact of laparoscopic sleeve gastrectomy on gastrointestinal motility.

Background: Because of the poor quality of life that results from the open technique (open excision and packing) for surgically treating pilonidal cyst disease, several alternatives that accelerate the wound-healing process have been proposed. This study aimed to evaluate the effect of platelet-derived growth factors on the healing process.

Methods: Fifty-two patients with pilonidal sinus disease who underwent open excision and secondary closure of the surgical wound (n = 22) or additional local postoperative infusion of platelet-derived growth factors (n = 30) were evaluated.

Background: Radiofrequency (RF) ablation has recently been expanded from palliative treatment into tissue-preserving surgery with controversial results. RF has been accused of septic complications and dysfunction of the target organ due to uncontrolled energy distribution. The aim of this study was to evaluate the short- and long-term implications of RF energy to the remaining splenic tissue after laparoscopic and open RF-assisted partial splenectomy.

Background: The intraoperative blood loss and the biliary leak constitute the major causes of postoperative morbidity following liver resection. We describe a new technique for liver parenchyma transection using the Atlas modification of the ligasure vessel sealing system. The gradual closure of the instrument may cause crushing of the hepatic tissue and heat sealing of the vessels and bile ducts at the same time.
