BACKGROUND: Robotic surgery for right-sided colon and rectal cancer has rapidly increased; however, there is limited evidence in the literature of advantages of robotic left colectomy (RLC) for left-sided colon cancer. The purpose of this study was to compare the outcomes of RLC versus laparoscopic left colectomy (LLC) with complete mesocolic excision (CME) for left-sided colon cancer. METHODS: Patients who had RLC or LLC with CME for left-sided colon cancer at 5 hospitals in China between January 2014 and April 2022 were included...

BACKGROUND: Methylene blue staining of the resected specimen has been described as an alternative to the conventional palpation and visual inspection method to improve lymph node harvest. This meta-analysis evaluates the usefulness of this technique in surgery for rectal cancer, particularly after neoadjuvant therapy. METHODS: Randomized controlled trials (RCTs) comparing lymph node harvest in methylene blue-stained rectal specimens to those of unstained specimens were identified from the Medline, Embase, and Cochrane databases...

PURPOSE: The standard treatment for chronic anal fissures that have failed non-operative management is lateral internal sphincterotomy. Surgery can cause de novo incontinence. Fissurectomy has been proposed as a sphincter/saving procedure, especially in the presence of a deep posterior pouch with or without a crypt infection. This study investigated whether fissurectomy offers a benefit in terms of de novo post-operative incontinence. METHODS: Patients surgically managed with fissurectomy or lateral internal sphincterotomy for chronic anal fissures from 2013 to 2019 have been included...

BACKGROUND: Patients with inflammatory bowel disease (IBD) who have had a total colectomy remain with their rectum in situ, and are therefore at risk of rectal carcinoma. It is not clear how high the incidence of rectal cancer is in this cohort. The primary objective of this meta-analysis was to estimate the incidence of rectal cancer in patients with ulcerative colitis or Crohn's disease who have undergone colectomy but have a residual rectum, and to identify the risk factors for its development...

PURPOSE: Adequate staging of early rectal neoplasms is essential for organ-preserving treatments, but magnetic resonance imaging (MRI) frequently overestimates the stage of those lesions. We aimed to compare the ability of magnifying chromoendoscopy and MRI to select patients with early rectal neoplasms for local excision. METHODS: This retrospective study in a tertiary Western cancer center included consecutive patients evaluated by magnifying chromoendoscopy and MRI who underwent en bloc resection of nonpedunculated sessile polyps larger than 20 mm, laterally spreading tumors (LSTs) [Formula: see text] 20 mm, or depressed-type lesions of any size (Paris 0-IIc)...

PURPOSE: Anorectal, sexual, and urinary dysfunction are common issues after rectal cancer surgery, although seldom explored. The primary aim of this study was to investigate postoperative anorectal functional results. METHODS: Patients with mid/low-rectal cancer treated with transanal TME (TaTME) with primary anastomosis with/without diverting stoma between 2015 and 2020 were reviewed and selected if they had a minimum follow-up of 6 months (from the primary procedure or stoma reversal)...

BACKGROUND: Rectal prolapse is a debilitating disorder of the pelvic floor, and treatment outcomes are variable. Previous studies have identified underlying benign joint hypermobility syndrome (BJHS) in some patients. We sought to determine the outcomes of these patients after undergoing ventral rectopexy surgery (VMR). METHODS: All consecutive patients who were referred to the pelvic floor unit at our institution between February 2010 and December 2011 were considered for recruitment into the study...

BACKGROUND: Rubber band ligation (RBL) is a widely accepted intervention for the treatment of haemorrhoids. However, post procedure pain is a common complaint. The aim of this study was to determine whether the addition of local anaesthetic (LA) to the haemorrhoid pedicle base, post RBL, aids in reducing early post-procedure pain. Additionally, to compare perceived perianal numbness, oral analgesia usage and total consumption, and adverse events. METHODS: This study was a prospective, single-blinded randomised controlled trial...

BACKGROUND: The injection of allogeneic adipose tissue-derived mesenchymal stem cells (MSC) into anal fistulas in patients with Crohn's disease has never been evaluated in "real-life" conditions in France. METHODS: We prospectively studied the first patients receiving MSC injections at our center and undergoing 12 months of follow-up. The primary endpoint was the clinical and radiological response rate. The secondary endpoints were symptomatic efficacy, safety, anal continence, quality of life (Crohn's anal fistula-quality of life scale, CAF-QoL), and predictive factors of success...

Artificial intelligence (AI) has the potential to revolutionize surgery in the coming years. Still, it is essential to clarify what the meaningful current applications are and what can be reasonably expected. This AI-powered review assessed the role of AI in colorectal surgery. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-compliant systematic search of PubMed, Embase, Scopus, Cochrane Library databases, and gray literature was conducted on all available articles on AI in colorectal surgery (from January 1 1997 to March 1 2021), aiming to define the perioperative applications of AI...

BACKGROUND: Robot-assisted ventral mesh rectopexy is considered a valid option in the treatment of rectal prolapse. However, it involves higher costs than the laparoscopic approach. The aim of this study is to determine if less expensive robotic surgery for rectal prolapse can be safely performed. METHODS: This study was conducted on consecutive patients who underwent robot-assisted ventral mesh rectopexy at Fondazione Policlinico Universitario "A. Gemelli" IRCCS, Rome, from 7 November 2020 to 22 November 2021...

BACKGROUND: Gracilis muscle interposition (GMI) has been associated with favorable outcomes in treating complex perianal fistulas. Outcomes of GMI may vary according to the fistula etiology, particularly between rectovaginal fistulas in women and rectourethral fistulas (RUF) in men. The aim of this study was to assess the outcome of GMI to treat RUF acquired after prostate cancer treatment. METHODS: This retrospective cohort study included male patients treated with GMI for RUF acquired after prostate cancer treatment between January 2000 and December 2018 in the Department of Colorectal Surgery, Cleveland Clinic Florida...

BACKGROUND: There are various preoperative treatments that are useful for controlling local or distant metastases in lower rectal cancer. For planning perioperative management, preoperative stratification of optimal treatment strategies for each case is required. However, a stratification method has not yet been established. Therefore, we attempted to predict the prognosis of lower rectal cancer using preoperative magnetic resonance imaging (MRI) with artificial intelligence (AI). METHODS: This study included 54 patients [male:female ratio was 37:17, median age 70 years (range 49-107 years)] with lower rectal cancer who could be curatively resected without preoperative treatment at Tokyo Medical University Hospital from January 2010 to February 2017...

BACKGROUND: Robotic surgery (RS) is increasingly employed in colorectal surgical practice, widening the range of surgical techniques offered to patients. We investigated the perceptions of patients with colorectal cancer in relation to RS, open surgery (OS) and conventional laparoscopic surgery (CLS), to identify ideas or assumptions which, in the context of shared surgeon-patient decision-making, may affect the resultant choice of surgical technique. We also investigated salient factors affecting patients' perioperative experience, including those of RS patients, to guide improvements in care and preoperative patient preparation...

BACKGROUND: Laparoscopy has been increasingly applied in colorectal surgery, and imaging systems have been improving concurrently. The present study aims to compare outcomes following colorectal surgery with the 4K and traditional high-definition (HD) video systems. METHODS: All consecutive patients undergoing laparoscopic colorectal surgery between April 2016 and June 2020 were retrospectively retrieved from a prospective institutional database. The study population was matched according to the imaging system (4K versus HD groups) through a propensity score matching (PSM) based on perioperative characteristics of 15 patients...
