Reinforced tension-line suture after laparotomy: early results of the Rein4CeTo1 randomized clinical trial.

Background: The aim was to investigate whether adding a reinforced tension-line (RTL) suture to a standard 4 : 1 small-bite closure would reduce the incidence of incisional hernia after colorectal cancer surgery.

Methods: Patients aged at least 18 years, who were scheduled for elective colorectal cancer surgery through a midline incision at two Swedish hospitals (2017-2021), were randomized in a 1 : 1 ratio to either fascial closure with RTL and 4 : 1 small-bite closure with polypropylene sutures (RTL group) or 4 : 1 small-bite closure with polydioxanone suture alone (PDS group). The primary outcome was CT-detected incisional hernia 1 year after surgery.

Predictive factors for recurrent acute appendicitis after conservative treatment.

Introduction: Conservative treatment of acute appendicitis is gaining popularity, and identifying patients with a higher risk of recurrence is becoming increasingly important. Previous studies have suggested that older age, male sex, diabetes, appendicolith and abscess formation may be contributing factors, however, results from the adult population are inconsistent.

Aim: This study aims to identify predictive factors for recurrent appendicitis after conservative treatment.

Oesophageal fluoroscopy in adults-when and why?

Oesophageal fluoroscopy is a radiological procedure that uses dynamic recording of the swallowing process to evaluate morphology and function simultaneously, a characteristic not found in other clinical tests. It enables a comprehensive evaluation of the entire upper gastrointestinal tract, from the oropharynx to oesophagogastric bolus transport. The number of fluoroscopies of the oesophagus and the oropharynx has increased in recent decades, while the overall use of gastrointestinal fluoroscopic examinations has declined.

Mold Odor from Wood Treated with Chlorophenols despite Mold Growth That Can Only Be Seen Using a Microscope.

We previously reported that indoor odorous chloroanisoles (CAs) are still being emitted due to microbial methylation of hazardous chlorophenols (CPs) present in legacy wood preservatives. Meanwhile, Swedish researchers reported that this malodor, described since the early 1970s, is caused by hazardous mold. Here, we examined to what extent CP-treated wood contains mold and if mold correlates with perceived odor.

Abdominal Closure With Reinforcing Suture Decreases Incisional Hernia Incidence After CRS/HIPEC.

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) entails several risk factors for incisional hernia (IH). A few reports available showing incidences between 7% and 17%. At our institution fascia closure has been performed in a 4:1 suture to wound length manner, with a continuous 2-0 polydiaxanone suture (PDS-group) or with a 2-0 polypropylene suture preceded by a reinforced tension line (RTL) suture (RTL-group).

Intussusception After Roux-en-Y Gastric Bypass: Correlation Between Radiological and Operative Findings.

Introduction: Intussusceptions diagnosed on computed tomography (CT) scans in Roux-en-Y gastric bypass (RYGB) patients could cause serious small bowel obstruction (SBO) or be an incidental finding. The objective of this study was to correlate radiological findings with clinical outcomes to differentiate intussusceptions requiring emergent surgery for SBO.

Methods: A search for acute abdominal CT scans reporting intussusceptions in RYGB patients between 2012 and 2019 at Skåne University Hospital, Malmö, Sweden, retrieved 35 scans.

Extravascular incidental findings in computed tomography angiography are associated with lower amputation-free survival in patients with acute lower limb ischaemia.

Motility index measured by magnetic resonance enterography is associated with sex and mural thickness.

Background: Recently, a technique has been developed to use magnetic resonance enterography (MRE) for the evaluation of small bowel motility. The hypothesis was that assessment of the motility index (MI) should reflect differences in motility between clinical conditions.

Aim: To aim of the present observational, cross-sectional study was to evaluate the use of the MI in daily clinical practice.

Quantified small bowel motility in patients with ulcerative colitis and gastrointestinal symptoms: a pilot study.

Background: Gastrointestinal (GI) symptoms are common in patients with ulcerative colitis (UC), even when the disease is in remission, possibly due to abnormalities in GI motility. Small bowel motility can be assessed globally and in specific intestinal regions during magnetic resonance enterography (MRE) using a displacement mapping technique.

Purpose: To investigate whether small bowel motility in MRE differs between patients with UC and controls, and if altered motility correlates with GI symptoms.

Validation of computed tomography angiography using mean arterial pressure gradient as a reference in stented superior mesenteric artery.

Purpose: The aim of this prospective study was to validate the diagnostic performance of computed tomography angiography (CTA) in endoprosthesis stenosis in the superior mesenteric artery (SMA) using mean arterial pressure (MAP) gradients during angiography as a reference method.

Methods: Twenty-nine patients with mesenteric atherosclerotic disease underwent 45 paired measurements of endoprosthesis stenosis in the SMA with CTA and MAP gradients between March 2009 and July 2015. The grade of endoprosthesis stenosis in the SMA at CTA using the TeraRecon Aquarius workstation was correlated with MAP gradients.

Volumetric analysis of small bowel motility in an unselected cohort of patients with Crohn's disease.

Background: Quantified terminal ileal motility during magnetic resonance enterography (MRE) has been suggested to be used as a biomarker of Crohn's disease (CD). The aim of the present study was to evaluate this method in clinical practice.

Methods: Healthy volunteers and all consecutive patients referred to MRE during a 2-year period were asked to participate and complete the Irritable Bowel Syndrome-Symptom Severity Scale (IBS-SSS) to assess gastrointestinal symptoms.

Simultaneous X-ray Video-Fluoroscopy and Pulsed Ultrasound Velocimetry Analyses of the Pharyngeal Phase of Swallowing of Boluses with Different Rheological Properties.

The Ultrasound Velocity Profiling (UVP) technique allows real-time, non-invasive flow mapping of a fluid along a 1D-measuring line. This study explores the possibility of using the UVP technique and X-ray video-fluoroscopy (XVF) to elucidate the deglutition process with the focus on bolus rheology. By positioning the UVP probe so that the pulsed ultrasonic beam passes behind the air-filled trachea, the bolus flow in the pharynx can be measured.

Radiological findings in anastomotic leakage after anterior resection may predict a permanent stoma.

Background: Permanent stoma (PS) is common following treatment of anastomotic leakage (AL) after anterior resection (AR) and ways of predicting successful treatment outcome are missing.

Purpose: To explore radiological variables in rectal contrast studies in their relation to end-result of PS following treatment for AL after AR.

Material And Methods: The Swedish Cancer Registry (SCRCR) was explored for AL cases after AR for rectal cancer in patients operated in the region of Skåne from 1 January 2001 to 31 December 2011.

Assessment of the Food-Swallowing Process Using Bolus Visualisation and Manometry Simultaneously in a Device that Models Human Swallowing.

The characteristics of the flows of boluses with different consistencies, i.e. different rheological properties, through the pharynx have not been fully elucidated.

A Device that Models Human Swallowing.

The pharynx is critical for correct swallowing, facilitating the transport of both air and food transport in a highly coordinated manner, and aberrant co-ordination causes swallowing disorders (dysphagia). In this work, an in vitro model of swallowing was designed to investigate the role of rheology in swallowing and for use as a pre-clinical tool for simulation of different routes to dysphagia. The model is based on the geometry of the human pharynx.
