The surgical management of ulcerative colitis (UC) often involves complex operations. We investigated the outcome of patients who underwent surgery for UC by analyzing a nationwide database. ⋯ Results from a large nationwide database demonstrate that a laparoscopic approach was utilized in an increasing number of UC patients undergoing colectomy and was associated with lower morbidity and mortality, even in more complex procedures, such as TAC and IPAA.

Incisional hernia is a frequent complication after abdominal surgery. Today open sublay mesh repair and the laparoscopic intraperitoneal onlay mesh repair are the most widely used techniques for its cure. We developed a laparoscopic transperitoneal sublay mesh repair for the treatment of small- and medium-size ventral and incisional hernias. Outcomes of the new technique and the Rives-Stoppa repair were compared. ⋯ Our initial results indicate that the new laparoscopic transperitoneal sublay mesh repair is a safe and effective method for the treatment of small- and medium-size ventral and incisional hernias.

Randomized Controlled Trial
High positive end-expiratory pressure preserves cerebral oxygen saturation during laparoscopic cholecystectomy under propofol anesthesia.
Positive end-expiratory pressure (PEEP) can improve respiratory mechanics during pneumoperitoneum, but may influence intracranial and cerebral perfusion pressure. This study investigated the changes in hemodynamic parameters and cerebral oxygen saturation (rSO(2)) associated with 10 cmH(2)O PEEP during pneumoperitoneum while undergoing laparoscopic cholecystectomy under propofol anesthesia. ⋯ Application of PEEP with 10 cmH(2)O during CO(2) pneumoperitoneum could preserve the rSO(2) value and hemodynamic stability in patients undergoing laparoscopic cholecystectomy under propofol anesthesia.

Comparative Study
Case-matched analysis comparing outcomes of revisional versus primary laparoscopic Roux-en-Y gastric bypass.
Laparoscopic Roux-en-Y gastric bypass (LRYGB) is one of the most common approaches used to revise post-bariatric patients with inadequate weight loss or significant weight regain. Previous studies have analyzed the outcomes of open revisional RYGB versus primary RYGB, but no case-control matched analysis comparing revisional LRYGB versus primary LRYGB has been performed. ⋯ Revisional LRYGB is characterized by lower EWL and higher morbidity than primary LRYGB. However, our data suggest that revisional LRYGB is still capable of providing significant weight loss in these high-risk patients.

Multicenter Study
The laparoscopic modified Sugarbaker technique is safe and has a low recurrence rate: a multicenter cohort study.
Parastomal hernia is a frequent complication of intestinal stomata. Mesh repair gives the best results, with the mesh inserted via laparotomy or laparoscopically. It was the aim of this retrospective multicenter study to determine the early and late results of the laparoscopically performed, modified Sugarbaker technique with ePTFE mesh. ⋯ The laparoscopic Sugarbaker technique is a safe procedure for repairing parastomal hernias. In our study, the overall morbidity was 19 % and the recurrence rate was 6.6 % after a mean follow-up of 26 months. Moreover, the laparoscopic approach revealed concomitant hernias in 41 % of the patients, which could be repaired successfully at the same time.
