Background: The ligation of intersphincteric fistula tract is a surgical technique designed to treat trans-sphincteric anal fistulas aiming to preserve sphincter integrity. Recent studies suggest its efficacy in short-term fistula healing with limited impact on continence. However, comprehensive prospective data on long-term outcomes, including recurrence and bowel continence, are limited.

Importance: Neoadjuvant short-course radiotherapy was routinely applied for nonlocally advanced rectal cancer (cT1-3N0-1M0 with >1 mm distance to the mesorectal fascia) in the Netherlands following the Dutch total mesorectal excision trial. This policy has shifted toward selective application after guideline revision in 2014.

Objective: To determine the association of decreased use of neoadjuvant radiotherapy with cancer-related outcomes and overall survival at a national level.

Background: It is often stated that loose seton drainage results in distal migration of a fistula tract in perianal fistula. The aim of the present study was to assess this distalization of trans- and suprasphincteric perianal fistulas after a silicone seton has been inserted.

Methods: Consecutive patients who underwent loose seton placement for the management of a transsphincteric or suprasphincteric fistula between January 2016 and December 2021 with a pre- and postoperative magnetic resonance imaging (MRI) were included in the present retrospective study.

JCO Whether adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) might prevent peritoneal metastases after curative surgery for high-risk colon cancer is an ongoing debate. This study aimed to determine 5-year oncologic outcomes of the randomized multicenter COLOPEC trial, which included patients with clinical or pathologic T4N0-2M0 or perforated colon cancer and randomly assigned (1:1) to either adjuvant systemic chemotherapy and HIPEC (n = 100) or adjuvant systemic chemotherapy alone (n = 102). HIPEC was performed using a one-time administration of oxaliplatin (460 mg/m, 30 minutes, 42°C, concurrent fluorouracil/leucovorin intravenously), either simultaneously (9%) or within 5-8 weeks (91%) after primary tumor resection.

Background: The ileostomy pathway, introduced in 2011, has proved to be successful in eliminating hospital readmissions for high-output ileostomy or dehydration in the following period of 7 months in a single institution. However, it is unclear whether this short-term success, immediately after the initiation of the program, can be sustainable in the long term.

Objective: The aim of this study was to assess the efficacy and the durability of the ileostomy pathway in reducing readmissions for dehydration over a longer period of time.

Background: In the recent years two innovative approaches have become available for minimally invasive en bloc resections of large non-pedunculated rectal lesions (polyps and early cancers). One is Transanal Minimally Invasive Surgery (TAMIS), the other is Endoscopic Submucosal Dissection (ESD). Both techniques are standard of care, but a direct randomised comparison is lacking.

Article Synopsis
  • A study aimed to compare the effectiveness of chronic seton drainage, anti-TNF therapy, and surgical closure in treating perianal Crohn's fistulas, focusing on the need for re-interventions after treatment.
  • The trial included 44 patients, but was halted early due to a lack of significant outcomes; seton drainage showed the highest re-intervention rates compared to the other two treatments.
  • The findings suggest that chronic seton drainage alone may not be a suitable treatment option for patients with this condition.

Background: Nearly a quarter of patients with locally advanced (T4 stage) or perforated colon cancer are at risk of developing peritoneal metastases, often without curative treatment options. We aimed to determine the efficacy of adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with locally advanced colon cancer.

Methods: This multicentre, open-label trial was done in nine hospitals that specialised in HIPEC in the Netherlands.

Background: Considerable morbidity (10-14%) and even mortality (4-30%) have been reported after reversal of intestinal continuity following Hartmann's procedure. Feasibility of and advantages in reducing peri- and postoperative morbidity by utilizing single-port techniques through the colostomy site have been suggested before in small case series. The purpose of the present prospective observational study is to evaluate the outcomes of reversal of intestinal continuity using single-port access in a relatively large consecutive cohort.

Purpose: This study has aimed to evaluate the effects of surgery on physical activity (PA), quality of life (QoL), and disease-specific health status, by analyzing the differences between sphincter-preserving surgery (low anterior resection (LAR)) and abdominoperineal resection (APR) among rectal cancer survivors.

Methods: Individuals who were diagnosed with rectal cancer and who underwent an APR or a LAR between 2000 and 2009 were included. The different questionnaires on QoL, disease-specific health status, and physical activity began their surveys in 2010.

Background: Transanal minimally invasive surgery (TAMIS) is considered the successor of transanal endoscopic microsurgery (TEMS). It makes use of more readily available laparoscopic instruments and single-port access platforms with similar perioperative, clinical and oncological outcomes. Little is known about quality of life (QoL) outcomes after the use of TAMIS.

Introduction: The completeness of the pathological examination of resected colon cancer specimens is important for further clinical management. We reviewed the pathological reports of 356 patients regarding the five factors (pT-stage, tumor differentiation grade, lymphovascular invasion, tumor perforation and lymph node metastasis status) that are used to identify high-risk stage II colon cancers, as well as their impact on overall survival (OS).

Methods: All patients with stage II colon cancer who were included in the first five years of the MATCH study (1 July 2007 to 1 July 2012) were selected (n = 356).

Background: Complications after restoration of intestinal continuity (RIC) following Hartmann's procedure occur frequently and are often serious. These complications result in a reported morbidity of 4-30 % and a reported mortality of 10-14 %. Reducing the amount of surgical trauma accompanying abdominal access seems an attractive tool to reduce perioperative morbidity.

Background: Currently, the preferred method for local excision of rectal polyps is transanal endoscopic microsurgery, avoiding rectal resection. Transanal minimally invasive surgery is a relatively new technique using a disposable port in combination with conventional laparoscopic instruments. This method is less expensive as compared with transanal endoscopic microsurgery, relatively easy to learn, and available.
