Influence of Conversion and Anastomotic Leakage on Survival in Rectal Cancer Surgery; Retrospective Cross-sectional Study

BackgroundConversion and anastomotic leakage in colorectal cancer surgery have been suggested to have a negative impact on long-term oncologic outcomes. The aim of this study in a large Dutch national cohort was to analyze the influence of conversion and anastomotic leakage on long-term oncologic outcome in rectal cancer surgery.MethodsPatients were selected from a retrospective...

Laparoscopic surgery for T4 colon cancer: a systematic review and meta-analysis

Background In colon cancer, T4 stage is still assumed to be a relative contraindication for laparoscopic surgery considering the oncological safety. The aim of this systematic review with meta-analysis was to evaluate short- and long-term oncological outcomes after laparoscopic surgery for T4 colon cancer, and to compare these with open surgery. Methods Using systematic review of...

Low Hartmann’s procedure or intersphincteric proctectomy for distal rectal cancer: a retrospective comparative cohort study

PurposeTwo non-restorative options for low rectal cancer not invading the sphincter are the low Hartmann’s procedure (LH) or intersphincteric proctectomy (IP). The aim of this study was to compare postoperative morbidity with emphasis on pelvic abscesses after LH and IP.MethodsAll patients that had LH or IP for low rectal cancer were included in three centres between 2008 and...

Locally Advanced Colorectal Cancer: True Peritoneal Tumor Penetration is Associated with Peritoneal Metastases

Background Findings show T4 colorectal cancer (CRC) to be a risk factor for the development of peritoneal metastases (PM). Heterogeneity regarding peritoneal involvement of T4 tumors might explain the wide range of reported PM incidences (8–50%). Hyperplastic and mesothelial inflammatory reactions complicate evaluation of the exact primary tumor involvement of the peritoneal...

Morbidity related to defunctioning ileostomy closure after ileal pouch-anal anastomosis and low colonic anastomosis

Purpose Defunctioning ileostomies are widely performed in order to prevent or treat anastomotic leakage after colorectal surgery. The aim of the present study was to determine morbidity related to stoma closure and to identify predictive factors of a complicated postoperative course. Methods A consecutive series of 138 patients were retrospectively analyzed after stoma reversal...

Alternative specimen extraction techniques after laparoscopic emergency colectomy in inflammatory bowel disease

Background Omitting the extraction site incision potentially further decreases the abdominal wall trauma in laparoscopic surgery. The purpose of this study was to report the results of alternative specimen extraction techniques after laparoscopic emergency colectomy in patients with inflammatory bowel disease (IBD). Methods Ten consecutive patients with IBD underwent (sub)acute...

Less adhesiolysis and hernia repair during completion proctocolectomy after laparoscopic emergency colectomy for ulcerative colitis

Background The aim of this study was to determine whether the need for adhesiolysis during completion proctectomy (CP) with ileopouch anal anastomosis (IPAA) is influenced by the surgical approach of the initial emergency colectomy for ulcerative colitis and the hospital setting. Methods One hundred consecutive patients who underwent CP with IPAA in our center between January...

Sexual and urinary functioning after rectal surgery: a prospective comparative study with a median follow-up of 8.5 years

Purpose The purpose of this study was to prospectively compare rectal resection (RR) with colonic resection on sexual, urinary and bowel function and quality of life in both short-term and long-term. Methods Eighty-three patients who underwent RR were compared to 53 patients who underwent a colonic resection leaving the rectum in situ (RIS). A questionnaire assessing sexual...

Surgical Treatment of Renal Cell Cancer Liver Metastases: A Population-Based Study

BackgroundTo evaluate outcomes of surgical treatment in patients with hepatic metastases from renal-cell carcinoma in the Netherlands, and to identify prognostic factors for survival after resection. Renal-cell carcinoma has an incidence of 2,000 new patients in the Netherlands each year (12.5/100,000 inhabitants). According to literature, half of these patients ultimately...

Randomized controlled multicentre study comparing biological mesh closure of the pelvic floor with primary perineal wound closure after extralevator abdominoperineal resection for rectal cancer (BIOPEX-study)

Background Primary perineal wound closure after conventional abdominoperineal resection (cAPR) for rectal cancer has been the standard of care for many years. Since the introduction of neo-adjuvant radiotherapy and the extralevator APR (eAPR), oncological outcome has been improved, but at the cost of increased rates of perineal wound healing problems and perineal hernia. This has...
