Challenges in the treatment of a giant retroperitoneal liposarcoma.

Background: Retroperitoneal soft-tissue sarcoma is a very rare neoplasm, the most frequent histological subtype is liposarcoma with up to 45% of all cases. Unspecific clinical presentation, late diagnosis and high local recurrence rate represent important problems in clinical practice. We present the case of an adult patient with an unusual large liposarcoma of the retroperitoneum analyzing diagnostic workup, surgical approach and therapeutic strategies.

Incisional hernia at the site of stoma reversal-incidence and risk factors in a retrospective observational analysis.

Background: The closure of a stoma site has a high incidence of incisional hernia (IH) development, reaching 30% in some studies. Location and defect size in the abdominal wall depend on the type of stoma formed, most commonly a loop ileostomy or terminal sigmoid colostomy.

Methods: The retrospective single-centre study includes all consecutive patients who underwent stoma reversal between 2010 and 2016 at the Department of Visceral, Transplant and Thoracic Surgery in Innsbruck.

Damage control surgery for perforated diverticulitis: a two center experience with two different abdominal negative pressure therapy devices.

The adoption of abdominal negative pressure therapy (NPT) during urgent laparotomy has shown to be helpful to control abdominal sepsis, improve morbidity and increase anastomosis rate. The aim of this study was to compare feasibility and outcome of two different abdominal negative pressure devices. The retrospective two-center study includes 78 consecutive patients with perforated sigmoid diverticulitis, who underwent urgent laparotomy using the ABThera™ (KCI, Wien, Austria) abdominal NPT device (Group A,  = 51) or the Suprasorb® CNP (Lohmann & Rauscher, Wien, Austria) abdominal NPT device (Group B,  = 27).

Perianal minimally invasive surgery (PAMIS) for rectal stump resection after previous colectomy.

Purpose: Resection of a long rectal stump after previous colectomy or Hartmann procedure often requires a combined transperitoneal and transperineal approach because of limited access through a perineal incision alone. Risks associated with this procedure include iatrogenic injury to bowels, nerves, ureters, vessels and sexual organs. This study reports on the feasibility and safety of perianal minimally invasive surgery (PAMIS) for the resection of long rectal stumps that would otherwise require a combined transperitoneal and perianal approach.
