Colon colorectal anal

OBJECTIVE: Predicting the risk of anastomotic leak (AL) is of importance when defining the optimal surgical strategy in colorectal surgery. Our objective was to perform a systematic review of existing scores in the field. METHODS: We followed the PRISMA checklist (S1 Checklist). Medline, Cochrane Central and Embase were searched for observational studies reporting on scores predicting AL after the creation of a colorectal anastomosis. Studies reporting only validation of existing scores and/or scores based on post-operative variables were excluded...

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...

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: Despite advances in neoadjuvant chemoradiotherapy and anal sphincter-preserving surgery for rectal cancer, bowel dysfunction is still unavoidable and negatively affects patients' quality of life. In this longitudinal study, we aimed to investigate the changes in bowel function with follow-up time and the effect of neoadjuvant chemoradiotherapy on bowel function following low anterior resection for rectal cancer. METHODS: In this study, 171 patients with upper or middle rectal cancer who underwent low anterior resection between 2012 and 2018 were included...

BACKGROUND: Restorative proctocolectomy with ileal pouch-anal anastomosis improves the quality of life in patients with ulcerative colitis by the removal of diseased large bowel and preservation of the natural route of defecation. Although the surgery may improve preexisting extraintestinal manifestations in the joint, skin, and eyes, extraintestinal manifestations, particularly primary sclerosing cholangitis can persist after colectomy. OBJECTIVES: A systemic review of diagnosis and treatment of liver, joint, skin, and eye manifestations in patients with restorative proctocolectomy and ileal pouch-anal anastomosis for ulcerative colitis...

BACKGROUND: Socioeconomic inequities have implications in access to health care and may be associated with disparities in treatment and survival. OBJECTIVE: To investigate the impact of socioeconomic inequities on time to treatment and survival of anal squamous cell carcinoma. DESIGN: This is a retrospective study using a nationwide dataset. SETTINGS: The patients were selected from National Cancer Database enrolled from 2004 to 2016...

AIM: Venous thromboembolic events (VTEs) are relatively common adverse surgical complications. Extended VTE prophylaxis for 4 weeks is recommended after colorectal cancer surgery, but its use in inflammatory bowel disease surgery lacks high-quality evidence. This retrospective study aimed to assess and characterize VTEs within the first 30 days after ileal pouch-anal anastomosis (IPAA) procedures and subtotal colectomies (STCs) for ulcerative colitis (UC). METHODS: All patients who underwent IPAA for UC between 1 January 2017 and 31 December 2021 were included...

BACKGROUND: Chronic antibiotic refractory pouchitis after restorative proctocolectomy with ileal pouch-anal anastomosis, characterized by at least 4 weeks of pouchitis symptoms that have not responded to standard antibiotic therapy, presents a therapeutic challenge for patients and healthcare providers. OBJECTIVE: The aim of this narrative review was to summarize the current evidence regarding management of chronic antibiotic refractory pouchitis. DATA SOURCES: Studies were identified through search of PubMed database from the National Library of Medicine...

BACKGROUND: Up to 20% to 40% cases of redo ileal pouch anal anastomosis will result in pouch failure. Whether to offer a second redo procedure to maintain intestinal continuity remains a controversial decision. OBJECTIVE: To report our institutional experience of second redo ileal pouch anal anastomosis procedures. DESIGN: This was a retrospective review. Patient-reported outcomes were compared between patients undergoing second redos with those of patients undergoing first redos using propensity score matching to balance the 2 cohorts...

AIM: Quality of life (QoL) is a crucial and core outcome in assessing the effectiveness of treatments for cryptoglandular anal fistula. Despite its extensive impact, there is a lack of patient-centred, disease-specific QoL measurement instruments of adequate quality. The aim of this study is to develop a disease-specific measurement instrument that can accurately measure QoL for patients with cryptoglandular anal fistula. METHOD: Semi-structured qualitative patient interviews and a systematic review of current instruments were used to generate items for the draft instrument...

BACKGROUND: There is no criterion to guide and evaluate the anastomosis of laparoscopic low anterior resection (LAR). We developed a new technique for precise anastomosis. This study endeavored to evaluate the effectiveness and safety of this new technology. METHODS: Patients with mid-low rectal cancer who underwent laparoscopic LAR in our department were enrolled retrospectively between January 1, 2021 and July 1, 2023. During the LAR, the distance between the sacral promontory and the rectal stump was measured and used to determine the length of the sigmoid colon, which was preserved for anastomose...

BACKGROUND: Venous thromboembolism occurs in approximately 2% of patients undergoing abdominal and pelvic surgery for cancers of the colon, rectum, and anus, and is considered preventable. The American Society of Colon and Rectal Surgeons recommends extended prophylaxis in high-risk patients, but there is low adherence to the guidelines. OBJECTIVE: This study aims to analyze the impact of venous thromboembolism risk-guided prophylaxis in patients undergoing elective abdominal and pelvic surgeries for colorectal and anal cancers from 2016 to 2021...

Subepithelial rectal lesions, including gastrointestinal stromal tumours (GIST), leiomyomas, neuroendocrine tumours, lipomas, and schwannomas, are rare surgical conditions. 1 Surgical management in this region often entails radical surgical excisions with stoma creation. Radical surgical excisions with stoma creation are often required for surgical management in this region. In this video, we demonstrate a transanal minimally invasive surgery (TAMIS) approach to anterior low rectal GIST. Patient underwent neoadjuvant Imatinib Mesylate after multidisciplinary team discussion, and were evaluated preoperatively with colonoscopy, pelvis MRI, and endoscopic ultrasound-guided tissue biopsy...

Inflammatory myofibroblastic tumors (IMTs) are neoplastic lesions characterized by the proliferation of spindle cells with myofibroblastic features and lymphocyte infiltration. Primary lesions can develop in several locations but rarely arise in the colon as described herein. The present case was that of a 69-year-old woman who visited our hospital with complaints of bloody bowel discharge and a prolapsed mass from the anus. A 20-mm tumor was identified on visual and digital examination. Lower gastrointestinal endoscopy revealed a pedunculated, elevated lesion above the dentate line, which showed contrast enhancement on abdominal computed tomography...

A 77-year-old man with complaining of anemia and abdominal pain was admitted to our hospital. An abdominal computed tomography showed the sigmoid colon tumor with bowel obstruction. Laparoscopic transverse colostomy was performed to release intestinal obstruction. After first operation, he was diagnosed the sigmoid colon cancer: cT4b(bladder), cN0, cM0, and cStage Ⅱc. Radical laparoscopic operation(Hartmann's operation)was performed. On the 4th postoperative day, fecal juice was discharged from the abdominal drain placed in the Douglas fossa, so emergency laparotomy was performed...

A 27-year-old man was referred to our hospital for a detailed examination of abdominal distention, bloody stool, anorectal pain, and weight loss. A colonoscopy revealed a circumferential type 2 tumor at 9 cm from the anal verge which was diagnosed as an adenocarcinoma based on biopsy. Contrast-enhanced CT of the abdomen showed an elevated perineal lipid concentration in the rectum(Ra)which was suspicious for clinical T4a stage, and simultaneous S7/8 liver metastasis. We strongly suspected familial adenomatous polyposis(FAP)because his mother had a past history of total proctocolectomy for FAP...

AIM: Natural orifice specimen extraction (NOSE) in left-sided colorectal surgery requires application of the circular stapler anvil to the proximal bowel without exteriorization through an additional abdominal incision. We describe an intracorporeal method to secure the stapler anvil, termed the intracorporeal antimesenteric ancillary trocar (IAAT) technique. METHOD: The ancillary trocar is attached to the stapler anvil before introduction into the abdominal cavity through the anal or vaginal orifice...

AIM: The purpose of this study is to assess US operative trends and outcomes of ulcerative colitis (UC) patients undergoing total proctocolectomy with ileal pouch-anal anastomosis (TPC-IPAA) or completion proctectomy with IPAA (CP-IPAA). METHODS: Adult UC patients who underwent TPC-IPAA or CP-IPAA were analysed retrospectively using the 2016-2020 American College of Surgeons National Surgical Quality Improvement Program database. Factors associated with 30-day overall and serious morbidity were identified using multivariable logistic regression...

AIM: The heterogeneity in data quality presented in studies regarding Crohn's anal fistula (CAF) limit extrapolation into clinical practice. The ENiGMA collaborators established a core descriptor set to standardize reporting of CAF. The aim of this work was to quantify the use of these descriptors in recent literature. METHOD: We completed a systematic review of PubMed and the Cochrane Library, extracting publications from the past 10 years specific to the clinical interventions and outcomes of CAF, and reported in line with PRISMA guidance...

BACKGROUND: Ileal pouch-anal anastomosis is considered the procedure of choice for restorative surgery after total colectomy for ulcerative colitis. Previous studies have examined the rate of ileal pouch-anal anastomosis within individual states, but not at the national level in the United States. OBJECTIVE: Assess the rate of ileal pouch-anal anastomosis after total colectomy for ulcerative colitis in a national population and identify factors associated with ileal pouch-anal anastomosis...
