Methods: An in vivo porcine laparoscopic model course was developed to simulate seven di...

Background: In colorectal cancer, C-reactive protein (CRP) levels on postoperative days 3-4 have a strong negative predictive value for an anastomotic leak, with threshold values of ~15 on post-operative day (POD) 3 and ~13 on POD 4. In Crohn's disease, CRP levels are perceived as unreliable in the postoperative period because of the underlying in...

Background Entero-atmospheric fistula (EAF) is a devastating rare complication after abdominal surgery. When parenteral feeding is not feasible, an enteral feeding access must be obtained. A Trans-Fistula Percutaneous Endoscopic Jejunostomy (TF-PEJ) approach is presented. Case presentation A young male that underwent emergent pancreatoduodenectomy...

Background: In colorectal cancer, CRP levels on postoperative days 3-4 have a strong negative predictive value for an anastomotic leak, with threshold values of ~15 on POD 3 and ~13 on POD 4. In Crohn’s disease, CRP levels are perceived as unreliable in the postoperative period because of the underlying inflammatory process. The aim of this study w...

Background: Air leak tests (ALTs) and dye leak tests (DLTs) are the most common techniques for Intraoperative colorectal anastomosis assessment. The aim of our study was to compare the sensitivity of ALT with DLT in intraoperative evaluation of colorectal anastomotic integrity and to quantify the pressures routinely used in these tests. Methods:...

Post operative ventral hernias are common following Hartmann's procedure. There is a debate whether hernia repair is safe when performed concomitantly with colostomy closure. In this study we aimed to evaluate the outcomes of synchronous Hartmann reversal (HR) with a hernia repair, compared to a staged procedure. A retrospective multi-center study...

Background: Following an intestinal anastomotic leak, stoma creation may be the safest approach. However, this method may be challenging and cause significant morbidity. In selected cases, a T drain approach can be beneficial and a stoma can be avoided. Objectives: To present one group's experience with a T drain approach for anastomotic leaks....
