Central ligation or partial preservation of the right gastric artery does not seem to affect conduit or anastomotic perfusion during robot-assisted resection of gastroesophageal junction cancer: a randomized clinical trial.

The gastric conduit can be created with partial preservation or a central ligation of the right gastric artery. Central ligation may facilitate complete removal of lymph node (LN) station 3; however, whether this influences conduit and anastomotic perfusion is unknown. Hence this study investigated whether a central ligation of the right gastric artery would affect conduit or anastomotic perfusion compared with partial preservation (local standard) during robot-assisted resection of gastroesophageal junction cancer.

Background And Objective: Minimally invasive liver surgery is evolving worldwide, and robot-assisted liver surgery (RLS) can deliver obvious benefits for patients. However, so far no large case series have documented the learning curve for RLS.

Methods: We conducted a retrospective study for robotic liver surgery (RLS) from June 2019 to June 2022 where 100 patients underwent RLS by the same surgical team.

Lower urinary tract injuries in patients with pelvic fractures at a level 1 trauma center - an 11-year experience.

Background: Urological injuries can occur in patients with pelvic fractures. Treatment recommendations lack solid evidence and is often pragmatical. There is a continuous need to describe short- and long-term morbidity following lower urinary tract trauma.

Intraoperative near-infrared lymphography with indocyanine green may aid lymph node dissection during robot-assisted resection of gastroesophageal junction cancer.

Background: Adequate lymphadenectomy during gastroesophageal junction (GEJ) cancer resection is essential, because lymph node (LN) metastasis correlates with increased recurrence risk. Fluorescence lymphography with indocyanine green (ICG) has been used for LN mapping in several surgical specialties; however, reports on GEJ cancer are lacking. Therefore, we investigated whether intraoperative ICG lymphography could facilitate LN harvest during robot-assisted resection of GEJ cancer.

Association between bacterial growth in chest tube and anastomotic leakage after esophageal resection: prospective cohort study.

Purpose: The aim of this study was to examine whether collagenase producing bacteria could be detected, in fluid collected from chest tubes, before clinical presentation of anastomotic leakage after esophageal resection.

Methods: We conducted a prospective single-center study of patients who underwent resection of the gastroesophageal junction. All patients had a chest tube placed in the pleural cavity perioperatively.

Mesenteric traction syndrome - Incidence, impact, and treatment: A systematic scoping review of the literature.

Background: Mesenteric traction syndrome (MTS) is commonly seen during major abdominal surgery and is characterised by facial flushing, hypotension, and tachycardia 15 min into surgery. MTS also impacts the postoperative course, as severe MTS has been associated with increased postoperative morbidity. However, despite MTS being common and severe MTS causing increased postoperative morbidity, the gaps in the literature are not clearly defined.

Evaluation of the systemic inflammatory response, endothelial cell dysfunction, and postoperative morbidity in patients, receiving perioperative corticosteroid, developing severe mesenteric traction syndrome - an exploratory study.

Objective: To determine whether a severe mesenteric traction syndrome (MTS) leads to increased surgical stress, endothelial dysfunction, and postoperative morbidity in a cohort in which all patients received a single dose of methylprednisolone.

Introduction: Preoperatively administered corticosteroids lower the incidence of severe MTS and may also attenuate surgical stress and endothelial damage associated with the development of severe MTS, ultimately lowering the postoperative morbidity.

Methods: This exploratory study analyzed prospectively collected data from 45 patients all receiving 125 mg methylprednisolone.

Expertise in colonoscopy intubation does not predict diagnostic accuracy: a simulation-based study.

 Studies have linked cecal intubation rate with adenoma detection rate; however, the direct association between technical performance during colonoscopy intubation and withdrawal has never been explored. Thus, it remains unclear whether gentle and efficient intubation predicts superior mucosal inspection. The aim of this study was to investigate the correlation between performance during intubation and withdrawal in a simulation-based setup.

Colonoscope retraction technique and predicting adenoma detection rate: a multicenter study.

Background And Aims: The success of preventing colorectal cancer relies on the expertise of the colonoscopists. Studies suggest that the retraction technique is a powerful indicator of expertise in distinguishing endoscopists with various adenoma detection rates (ADRs). We aimed to develop a retraction technique score and explore the correlation between endoscopists' retraction technique and their ADRs.

Intestinal perfusion assessed by quantitative fluorescence angiography in piglets with necrotizing enterocolitis.

Background: Reduced intestinal perfusion is thought to be a part of the pathogenesis in necrotizing enterocolitis (NEC). This study aims to evaluate the intestinal perfusion assessment in NEC-lesions by quantitative fluorescence angiography with indocyanine green (q-ICG) during laparoscopy and open surgery.

Methods: Thirty-four premature piglets were delivered by cesarean section and fed with parenteral nutrition and increasing infant formula volumes to induce NEC.

Time to maximum indocyanine green fluorescence of gastric sentinel lymph nodes and feasibility of combined indocyanine green/sodium fluorescein gastric lymphography.

Purpose: Indocyanine green (ICG) and sodium fluorescein (SF) are fluorescent dyes used for sentinel lymph node mapping. In oncological gastric surgery, ICG lymphography has increased the number of resected lymph nodes. However, the optimal time to administer ICG is unclear, and both preoperative and intraoperative injections have been practised.

Mesenteric traction syndrome in pigs: A single-blinded, randomized controlled trial.

Background: Mesenteric traction syndrome is commonly observed in patients undergoing upper abdominal surgery and is associated with severe postoperative complications. A triad of hypotension, tachycardia, and facial flushing seems provoked by prostacyclin (PGI) release from the gut in response to mesenteric traction. The administration of nonsteroidal anti-inflammatory drugs (NSAID) inhibits PGI release, stabilizing the hemodynamic response.

Quantitative fluorescence angiography aids novice and experienced surgeons in performing intestinal resection in well-perfused tissue.

Background: Anastomotic leakage (AL) after gastrointestinal resection is a devastating complication with huge consequences for the patient. As AL is associated with poor blood supply, tools for objective assessment of perfusion are in high demand. Indocyanine green angiography (ICG-FA) and quantitative analysis of ICG-FA (q-ICG) seem promising.

Severe mesenteric traction syndrome is associated with increased systemic inflammatory response, endothelial dysfunction, and major postoperative morbidity.

Unlabelled: This study aimed to determine if mesenteric traction syndrome (MTS) triggers increased systemic inflammation and endothelial cell dysfunction. Patients developing severe MTS had pronounced early IL6 elevations followed by endothelial cell damage. Furthermore, these processes were associated with increased postoperative morbidity.
