The malignant transformation of chronic fistula in ano is rare, accounting for 3% to 11% of all anal canal malignancies. It results from long-standing inflammation and chronic irritation. No guidelines are available for the management of these cases. We herein present a case report of a 55-year-old man who presented with a history of constipation, perianal pain, and discharging fistula in ano of 4-year duration and underwent fistula surgery with recurrence. Biopsy of the fistulous tract revealed adenocarcinoma...

One of the possible causes of chronic constipation is colonic duplication. Although seldom asymptomatic, its diagnosis is important due to the risk of malignancy that it carries. We present a case of a young female patient with long-standing constipation who was referred to Kolorektal Cerrahi Clinic (Izmir, Turkey) after scans revealed tubular type of colonic duplication. We successfully performed a laparoscopic total colectomy, and she recovered well. Identifying the type of duplication is important to ensure adequate resection and treatment...

PURPOSE: Prehabilitation (PH) is purported to improve patients' preoperative functional status. This systematic review and meta-analysis sought to compare short-term postoperative outcomes between patients who underwent a protocolized PH program and the existing standard of care among colorectal cancer patients awaiting surgery. METHODS: A search in MEDLINE/PubMed, the Cochrane Library, Embase, Scopus, and CINAHL was conducted to identify relevant articles. Repetitive and exhaustive combinations of MeSH search terms ("prehabilitation," "colorectal cancer," "colon cancer," and "rectal cancer") were used to identify randomized and nonrandomized studies comparing PH versus standard of care for colorectal cancer patients awaiting surgery...

The effectiveness of closed drainage tube insertion after low anterior resection has been controversial. We believe that drain tube displacement, which occurs up to 35% in real clinical practice, reduces the effectiveness of the drain tube. We report in this video a simple way to secure the drain tube in the pelvic cavity after low anterior resection and introduce a case that used the drain fixation method and treated anastomotic leakage without interventional procedure.

The benefits of minimally invasive approaches in colorectal surgery have been well demonstrated. However, some hesitancy remains with regards to the utilization of the robotic platform for total colectomies, mostly due to the perceived need for multiple re-dockings in multiquadrant surgery. This video aims to demonstrate how the robotic platform can be efficiently utilized in multiquadrant surgery without the need for multiple re-dockings, as well as some tips on how to overcome the potential challenges that may be encountered during this procedure...

PURPOSE: Colorectal cancer (CRC) is the most frequent cancer with limited therapeutic achievements. Recently, adoptive cellular immunotherapy has been developed as an antitumor therapy. However, its efficacy has not been tested in CRC. This study investigated the ability of an immune cell cocktail of dendritic cells (DCs), T cells, and natural killer (NK) cells to overcome immunological hurdles and improve the therapeutic efficacy of cell therapy for CRC. METHODS: CRC lysate-pulsed monocyte-derived DCs (Mo-DCs), CRC antigen-specifically expanded T cells (CTL), and in vitro-expanded NK cells were cultured from patient peripheral blood mononuclear cells (PBMC)...

Anastomotic and rectal stump leaks are feared complications of colorectal surgery. Diverting stomas are commonly used to protect low rectal anastomoses but can have adverse effects. Studies have reported favorable outcomes for transanal drainage devices instead of diverting stomas. We describe our use of the Heald anal stent and its potential impact in reducing anastomotic or rectal stump leak after elective or emergency colorectal surgery. We performed a single-center retrospective analysis of patients in whom a Heald anal stent had been used to "protect" a colorectal anastomosis or a rectal stump, in an elective or emergency context, for benign and malignant pathology...

JOURNAL ARTICLE
Pankaj Garg, Anvesha Mongia
Anal fistulas, especially complex and high fistulas, are difficult to manage. The transanal opening of the intersphincteric space (TROPIS) procedure was first described in 2017, and a high success rate of over 90% was reported in high complex fistulas. Since then, more studies and even a meta-analysis have corroborated the high efficacy of this procedure in high fistulas. Conventionally, the main focus was to close the internal (primary) opening for the fistula to heal. However, most complex fistulas have a component of the fistula tract in the intersphincteric plane...

PURPOSE: Submucosa-limited (pathological T1, pT1) colorectal cancers (CRCs) pose a continuing challenge in the choice of treatment options, which range from local excision to radical surgery. The aim of this study was to evaluate the morphometric and morphologic risk factors associated with regional lymph node metastasis (LNM) in pT1 CRC. METHODS: We performed a histological review of patients who underwent oncological resection between 2016 and 2022. Tumor grade, budding, poorly differentiated clusters (PDCs), cancer gland rupture, lymphovascular invasion (LVI), and presence of deep submucosal invasion (DSI), as well as width, length, total area, and area of DSI, were evaluated as potential risk factors for LNM...

PURPOSE: Minimally invasive surgery (MIS) is currently the standard treatment for rectal cancer. However, its limitations include complications and incomplete total mesorectal resection (TME) due to anatomical features and technical difficulties. Transanal TME (TaTME) has been practiced since 2010 to improve this, but there is a risk of local recurrence and intra-abdominal contamination. We aimed to analyze samples obtained through lavage to compare laparoscopic TME (LapTME) and TaTME...
