This study aims to evaluate the role of colonic stenting as a bridge to surgery in acutely obstructed left-sided colon cancer. Patients with acute left-sided malignant colonic obstruction with no evidence of peritonitis were recruited. After informed consent, patients were randomized to colonic stenting followed by elective surgery or immediate emergency(More)
The laparoscopic approach is increasingly becoming the gold standard for colorectal resections. While laparoscopic surgery of the left colon and rectum has been evaluated in many studies, laparoscopic resection of the right colon has not been as widely examined. The aim of this study was to examine the short-term outcomes after laparoscopic right(More)
Single-incision laparoscopic surgery (SILS) is a recent development of minimally invasive surgery for colorectal disease. The literature comparing it against conventional laparoscopic colectomy remains limited. A retrospective case–cohort study compared the benefits and outcomes of SILS right hemicolectomy (SRH) with those of conventional laparoscopic right(More)
Assessment of healing after low colorectal, colo-anal or ileo-pouch anal anastomosis is routinely performed with a water-soluble contrast enema (WSCE) prior to the reversal of the defunctioning stoma. Interpretation of these radiographs is sometimes difficult and imprecise. As these anastomoses are within the reach of a simple digital rectal examination(More)
INTRODUCTION A temporary loop ileostomy is often created to minimize the impact of peritoneal sepsis from an anastomotic dehiscence after a coloanal or low colorectal anastomosis. Such a stoma is usually closed after 6 to 12 weeks when the intestinal edema is reduced and the peristomal adhesions are less dense. This period is three to four times longer than(More)
OBJECTIVE The overall aim was to develop and validate a risk prediction score for laparoscopic colorectal surgery training cases. BACKGROUND Published risk prediction scores are not transferable between hospitals because they are derived from a single institution's data and are not designed for use in training situations. METHODS Cases from the(More)
INTRODUCTION Intestinal adhesion following abdominal surgery is a significant sequela to abdominal surgery. Intergel is a hyaluronate-based gel that reduces the incidence of postoperative adhesions when added to the peritoneal cavity before closure in gynecologic surgery. This is a randomized controlled trial evaluating the efficacy and safety of Intergel(More)
The ideal incision for laparoscopic specimen extraction is not known. There has been no randomised study thus far evaluating extraction site in laparoscopic colorectal surgery. The aim of our study was to compare post-operative outcomes, pain scores and quality of life scores of vertical periumbilical (VW) versus transverse left iliac fossa (TW) incisions(More)
Animal models have highlighted the importance of innate lymphoid cells (ILCs) in multiple immune responses. However, technical limitations have hampered adequate characterization of ILCs in humans. Here, we used mass cytometry including a broad range of surface markers and transcription factors to accurately identify and profile ILCs across healthy and(More)
INTRODUCTION Stapled hemorrhoidectomy (SH) has routinely been performed using Procedure for Prolapse and Hemorrhoids Proximate Hemorrhoidal Circular Staplers (Ethicon Endo-surgery, Cincinnati, OH). Premium Plus CEEA 34 (Tyco Healthcare, New Haven, CT) has been recently introduced for SH. This study aims to review the effectiveness of CEEA 34 for SH. (More)
