Article Synopsis
  • The study focuses on the complications that arise after oesophagogastric surgery and their impact on patient recovery.
  • The researchers analyzed surgeries performed at Galway University Hospital from 2014 to 2018 to evaluate the effectiveness of biomarkers like C-reactive protein (CRP) and CRP-lymphocyte ratio (CLR) in predicting postoperative morbidity, particularly anastomotic leaks (AL).
  • Findings show that CRP and CLR are effective indicators for predicting major complications, which can aid in improving patient care and recovery strategies.

Background: Advances in peri-operative oncological treatment, surgery and peri-operative care have improved survival for patients with oesophagogastric cancers. Neoadjuvant cancer treatment (NCT) reduces physical fitness, which may reduce both compliance and tolerance of NCT as well as compromising post-operative outcomes. This is particularly detrimental in a patient group where malnutrition is common and surgery is demanding.

Background: Following oesophagectomy, the most concerning complication is that of anastomotic leak (AL). Prompt diagnosis and intervention are crucial to facilitate an optimal outcome. Other complications, particularly respiratory, are not infrequent.

Purpose: The purpose of this paper is to evaluate staff opinion on the impact of the National Early Warning Score (NEWS) system on surgical wards. In 2012, the NEWS system was introduced to Irish hospitals on a phased basis as part of a national clinical programme in acute care.

Design/methodology/approach: A modified established questionnaire was given to surgical nursing staff, surgical registrars, surgical senior house officers and surgical interns for completion six months following the introduction of the NEWS system into an Irish university hospital.

Background: Urethral catheter (UC) removal is often delayed following colorectal resection due to the perceived increased risk of post-operative urinary retention (POUR) in patients with post-operative epidural analgesia (POEA). We aimed to determine if UC removal at 48 h, irrespective of ongoing POEA use, altered the risk of POUR and other morbidities associated with urethral catheterisation and immobility.

Methods: We performed a prospective randomised controlled pilot clinical study.

Background. One-fifth of people who develop colorectal cancer (CRC) have a first-degree relative (FDR) also affected. There is a large disparity in guidelines for screening of relatives of patients with CRC.

Background: Postoperative pain remains a significant challenge following laparoscopy. Aerosolized intraperitoneal local anesthetic (AILA) is a novel method to deliver local anesthetic. The aim was to evaluate aerosolized ropivacaine in pain management following laparoscopic Nissen fundoplication (LNF) and cholecystectomy (LC).

Study Objective: To evaluate intraperitoneal ropivacaine delivery with the AeroSurge device in the clinical setting and to evaluate the total systemic ropivacaine levels achieved following delivery of 50 mg of aerosolized ropivacaine.

Design: Preliminary, prospective, nonrandomized study.

Setting: Operating room of a university hospital.

Laparoscopic fundoplication (LF) is a surgical treatment for gastroesophageal reflux disease (GERD) that has been performed for more than 20 years. High-volume centers of excellence report long-term success rates greater than 90% with LF. On the other hand, general population-based outcomes are reported to be markedly worse, leading to a nihilistic perception of the procedure on the part of the medical referral population.

Purpose: Total mesorectal excision (TME) is the standard surgical treatment for rectal cancer. The roles of chemotherapy and radiotherapy have become more defined, accompanied by improvements in preoperative staging and histopathological assessment. We analyse our ongoing results in the light of changing patterns of treatment over consecutive time periods.

An 84 year-old gentleman presented with abdominal distension, anorexia and occasional epigastric pain over a four-week period. Blood parameters revealed a hypochromic microcytic anaemia. Both CT and US scan identified ascites and a mass in the left upper quadrant.

Purpose: Colorectal cancer (CRC) is a clinically diverse disease whose molecular etiology remains poorly understood. The purpose of this study was to identify miRNA expression patterns predictive of CRC tumor status and to investigate associations between microRNA (miRNA) expression and clinicopathological parameters.

Methods: Expression profiling of 380 miRNAs was performed on 20 paired stage II tumor and normal tissues.

The advent of minimally invasive surgery has facilitated the laparoscopic repair of diaphragmatic hernias. One of the difficulties associated with long-standing Bochdalek or Morgagni hernias is that the herniated contents are often quite adherent to the diaphragmatic defect and require considerable dissection before the reduction of herniated organs. Ultrasonic dissection using a harmonic coagulation shears allowed safe, bloodless division of the long-standing adhesions, which is essential for atraumatic reduction of herniated thoracic contents.

Background: Laparoscopic Nissen fundoplication (LNF) has established itself as the procedure of choice in the surgical management of the majority of patients suffering from gastroesophageal reflux disease (GERD). There are, however, few available data on the assessment of long-term failures after LNF.

Methods: We sought to clarify the mechanisms of failure among a group of patients who reported suboptimal results after LNF.
