Fluorescence angiography with indocyanine green for low anterior resection in patients with rectal cancer: a prospective before and after study.

Background: Inadequate bowel perfusion is among risk factors for colorectal anastomotic leaks. Perfusion can be assessed with indocyanine green fluorescence angiography (ICG) during colon resections. Possible benefits from its systematic use in high-risk patients with rectal cancer remain inconsistent.

TEMPOUR: A Randomized Controlled Trial Assessing Perioperative Use of An Alpha-1-Blocker to Reduce Postoperative Urinary Retention Following Transanal Endoscopic Microsurgery Procedures.

Background: Transanal endoscopic microsurgery is a treatment option for a wide range of rectal lesions. Postoperative urinary retention is a frequently associated complication. Some studies have suggested that the use of alpha-1-blockers may reduce the risk of postoperative urinary retention after hernia and colorectal surgery, but evidence is lacking.

Surgical management of rectal cancer with synchronous treatment of prostate cancer.

Purpose: To assess the safety and efficacy of synchronous treatments for rectal (RC) and prostate (PC) cancers.

Methods: Single-center retrospective study (2007-2021) of patients treated with neoadjuvant radiotherapy (RT) and total mesorectal excision (TME) for RC with synchronous PC treatment. The endpoints were 30-day postoperative severe complications, R0 resection rates, 3-year disease-free survival (DFS) and 3-year overall survival (OS).

Loop Ileostomy Closure as a 23-Hour Stay Procedure With Preoperative Efferent Limb Enteral Stimulation: A Randomized Controlled Trial.

Background: Loop ileostomy closure is a common procedure in colorectal surgery. Often seen as a simple operation associated with a low complication rate, it still leads to lengthy hospitalizations. Reducing postoperative complications and ileus rates could lead to a shorter length of stay and even ambulatory surgery.

Recurrence following transanal total mesorectal excision for rectal cancer: a monocentric retrospective series of technically difficult cases.

Purpose: Transanal total mesorectal excision (TaTME) has been proposed to overcome surgical difficulties encountered during rectal resection, especially for patients having high body mass index or low rectal cancer. The aim of this study was to evaluate oncologic outcomes following TaTME.

Methods: This retrospective study included all consecutive patients with rectal cancer who had a TaTME from 2013 to 2019.

Intracorporeal versus extracorporeal anastomosis in laparoscopic right hemicolectomy: a retrospective cohort study of anastomotic complications.

Purpose: Laparoscopic right hemicolectomy (LRH) can be performed with an intracorporeal anastomosis (IA) or extracorporeal anastomosis (EA). It is not clear which technique is best. This study evaluated the impact of each anastomosis technique on perioperative safety and postoperative evolution.

Prophylactic retromuscular mesh placement for parastomal hernia prevention: a retrospective cohort study of permanent colostomies and ileostomies.

Purpose: Parastomal hernia (PSH) is the most common complication of stoma formation. The safety and efficiency of prophylactically placing mesh to prevent PSH remain controversial. To address this question, we examined the incidence of clinical and radiological PSH when using parastomal prophylactic mesh (PPM).

Canadian taTME expert collaboration (CaTaCO) position statement.

Introduction: Transanal total mesorectal excision (taTME) is a novel approach to surgery for rectal cancer. The technique has gained significant popularity in the surgical community due to the promising ability to overcome technical difficulties related to the access of the distal pelvis. Recently, Norwegian surgeons issued a local moratorium related to potential issues with the safety of the procedure.

Transanal endoscopic microsurgery for rectal villous tumours: Can we rely solely on preoperative biopsies and the surgeon’s experience?

Background: Transanal endoscopic microsurgery has become the standard of treatment for rectal villous adenomas. However, the role of preoperative imaging for these lesions is not clear. The aim of this study was to compare the value of preoperative imaging and surgeon clinical staging in the preoperative evaluation of patients with rectal villous adenomas having transanal endoscopic microsurgery resection.

Prediction model and web-based risk calculator for postoperative ileus after loop ileostomy closure.

Background: Postoperative ileus (POI) is a significant complication after loop ileostomy closure given both its frequency and impact on the patient. The purpose of this study was to develop and externally validate a prediction model for POI after loop ileostomy closure.

Methods: The model was developed and validated according to the TRIPOD checklist for prediction model development and validation.

McKittrick-Wheelock Syndrome Presenting with Acute Kidney Injury and Metabolic Alkalosis: Case Report and Narrative Review.

A rare combination of severe volume depletion and electrolyte imbalance caused by a rectal villous adenoma is often referred to as the McKittrick-Wheelock syndrome. Patients usually seek medical care because of chronic hypersecretory diarrhea and display renal failure, metabolic acidosis, hyponatremia, and hypokalemia. We report the case of a 68-year-old woman who presented with this condition but showed unusual features such as severe hypokalemia and metabolic alkalosis, without diarrhea.

Assessing the safety and outcomes of repeat transanal endoscopic microsurgery.

Background: Transanal endoscopic microsurgery (TEM) is the treatment of choice for benign rectal tumors and select early rectal cancers. This surgical approach has become ubiquitous and surgeons are seeing recurrent lesions after TEM resection. This study aims to outline the safety and outcomes of repeat TEM when compared to primary TEM procedures.

Salvage TME following TEM: a possible indication for TaTME.

Background: Salvage surgery after transanal endoscopic microsurgery (TEM) has shown mixed results. Transanal total mesorectal excision (TaTME) might be advantageous in this population. The aim of this study was to assess the short-term oncologic and operative outcomes of salvage surgery after TEM, comparing TaTME to conventional salavge TME (sTME).

Tattooing or not? A review of current practice and outcomes for laparoscopic colonic resection following endoscopy at a tertiary care centre.

Background: Because small colonic tumours may not be visualized or palpated during laparoscopy, location of the lesion must be identified before surgery. The aim of this study was to evaluate the effectiveness of the current recommendation of endoscopic tattooing of lesions prior to laparoscopic colonic resections.

Methods: All consecutive patients who underwent elective laparoscopic resection for a colonic lesion at a single tertiary institution between 2013 and 2015 were identified for chart review.

Laparoscopic versus open colonic resection for complicated diverticular disease in the emergency setting: a safe choice? A retrospective comparative cohort study.

Background: We conducted a retrospective cohort study to compare the outcomes of laparoscopic colon resection (LCR) with open colon resection (OCR) for complicated diverticular disease (CDD) during emergent hospital admission.

Methods: Charts from all patients undergoing colon resection for CDD during emergent hospital admission at a single academic institution were reviewed. The primary outcomes were overall 30-day postoperative morbidity and mortality.

Laparoscopic emergency surgery for diverticular disease that failed medical treatment: a valuable option? Results of a retrospective comparative cohort study.

Background: Laparoscopic surgery has become the standard of treatment for elective management of diverticular disease. However, its use in the acute setting remains controversial.

Objective: The aim of this study is to compare the outcomes of laparoscopic surgery with open surgery in the acute management of complicated diverticular disease that failed initial medical treatment.

Low and high density lipoprotein metabolism in primary cultures of hepatic cells from normal and apolipoprotein E knockout mice.

Apolipoprotein E (apoE) plays a major role in lipoprotein metabolism by mediating the binding of apoE-containing lipoproteins to receptors. The role of hepatic apoE in the catabolism of apoE-free lipoproteins such as low density lipoprotein (LDL) and high density lipoprotein-3 (HDL(3)) is however, unclear. We analyzed the importance of hepatic apoE by comparing human LDL and HDL(3) metabolism in primary cultures of hepatic cells from control C57BL/6J and apoE knockout (KO) mice.
