Efficacy and safety of extended duration to perioperative thromboprophylaxis with low molecular weight heparin on disease-free survival after surgical resection of colorectal cancer (PERIOP-01): multicentre, open label, randomised controlled trial.

Objective: To determine the efficacy and safety of extended duration perioperative thromboprophylaxis by low molecular weight heparin when assessing disease-free survival in patients undergoing resection for colorectal cancer.

Design: Multicentre, open label, randomised controlled trial.

Settings: 12 hospitals in Quebec and Ontario, Canada, between 25 October 2011 and 31 December 2020.

Scandal mining: political nobodies and remediated visibility.

This article considers the 2015 federal election in Canada as the emergence of seemingly citizen-led practices whereby candidates' past missteps are unearthed and distributed through social and news media channels. On first pass, these resemble citizen-led engagements through digital media for potentially unmappable political goals, given the dispersed and either non-partisan or multi-partisan nature of these engagements. By bringing together journalistic accounts and social media coverage alongside current scholarship on citizenship and visibility, this case study traces the possibility of political accountability and the political weaponisation of mediated visibility through the targeted extraction of candidate details from dispersed profiles, communities and databases.

Plastic freezer bags: a cost-effective method to protect extraction sites in laparoscopic colorectal procedures?

Purpose: To review surgical-site infection (SSI) and retrieval-site tumor recurrence rates in laparoscopic colorectal procedures when using a plastic freezer bag as a wound protector.

Methods: Laparoscopic colorectal procedures where a plastic freezer bag used as a wound protector at the extraction site were reviewed between 1991 and 2008 from a prospectively collected database. χ test was used to compare SSI and tumor recurrence rates between groups.

Surgical residency training and international volunteerism: a national survey of residents from 2 surgical specialties.

Background: Many low- and middle-income countries (LMICs) lack basic surgical resources, resulting in avoidable disability and mortality. Recently, residents in surgical training programs have shown increasing interest in overseas elective experiences to assist surgical programs in LMICs. The purpose of this study was to survey Canadian surgical residents about their interest in international volunteerism.

Laparoscopic colostomy reversal after a Hartmann procedure: a prospective series, literature review and an argument against laparotomy as the primary approach.

Background: Open restoration of bowel continuity after a Hartmann procedure has been associated with significant morbidity, including anastomotic leak, incisional hernia, wound infections and inability to re-establish intestinal continuity. Few studies have examined the role of laparoscopy in performing a Hartmann reversal. The aim of this study was to review our laparoscopic Hartmann reversal (LHR) experience with an emphasis on intra- and postoperative adverse events.

Outpatient thyroid surgery: should patients be discharged on the day of their procedures?

Background: Outpatient surgery benefits patients and surgeons alike, as it is convenient, safe and cost-effective. We sought to assess the safety and feasibility of outpatient thyroid surgery (OTS) at an ambulatory site affiliated with a teaching hospital.

Methods: We performed a retrospective chart review of patients who underwent hemithyroidectomy, subtotal thyroidectomy, total thyroidectomy or completion thyroidectomy between 2002 and 2004 at the Riverside campus of The Ottawa Hospital.

Laparoscopic repair of paraesophageal hernias: a Canadian experience.

Background: The surgical approach to paraesophageal hernias (PEH) has changed with the advent of laparoscopic techniques. Variation in both perioperative outcomes and hernia recurrence rates are reported in the literature. We sought to evaluate the short- and intermediate-term outcomes with laparoscopic PEH repair.

The use of endoscopic hemoclips for postoperative anastomotic bleeding.

With the availability of endoscopy and its inherent use as a diagnostic and therapeutic modality, many surgeons and gastroenterologists are able to use this tool to remedy a wide range of gastrointestinal pathologies. The literature is replete with anecdotal endoscopic therapeutic strategies ranging from epinephrine injection, to use of cautery or argon plasma coagulation. This case report highlights the use of endoscopic hemoclips which were successfully applied in the acute postoperative period for a bleeding vessel at a fresh anastomotic site.

Nonsurgical treatment of chronic anal fissure: nitroglycerin and dilatation versus nifedipine and botulinum toxin.

Background: Surgical sphincterotomy for chronic anal fissure can cause fecal incontinence. This has led to the investigation of nonsurgical treatment options that avoid permanent damage to the internal anal sphincter.

Methods: We conducted a retrospective, ongoing chart review with telephone follow-up of 88 patients treated for chronic anal fissure between November 1996 and December 2002.
