Quality of life following laparoscopic inguinal hernia surgery with self-adhesive mesh in 552 patients: a two surgeon experience.

BACKGROUND: Given negative publicity surrounding surgical mesh in the media, the aim of this study was to assess post-operative morbidity and quality of life (QoL) following laparoscopic inguinal hernia surgery with self-adhesive ProgripTM mesh. METHODS: This study is a retrospective analysis of ProgripTM mesh for laparoscopic inguinal hernia repairs by two experienced surgeons in the public and private sectors. Data were collected by screening electronic clinical records. A sample of participants were contacted directly for QoL assessment using the Carolinas Comfort Scale (CCS). Descriptive statistical analysis was performed in Microsoft Excel. RESULTS: Five hundred and fifty-two patients had 648 hernia repairs using ProgripTM mesh from 2013 to 2019. The rate of hernia recurrence was 0.2% (n = 1). The rate of reoperation was 0.5% (n = 3). There were no mesh explant procedures, no adhesion-related readmissions and no perioperative deaths. Haematoma was the most common post-operative complication, occurring in 3.1% of participants (n = 17). The CCS assessment had a response rate of 55.8%. A total of 93% of CCS questions were answered with no sensation of mesh, 92% with no pain and 98% with no movement limitation. No participants reported severe or disabling symptoms. CONCLUSION: In this cohort, laparoscopic inguinal hernia repair with ProgripTM has shown a low recurrence rate and excellent post-operative QoL. The QoL data shows that the public perception of mesh based on media reports of complications may not be relevant for this operation. The knowledge gained from this study reinforces the potential value of a national mesh registry such as those seen overseas.

The impact of the COVID-19 pandemic on colorectal cancer diagnosis and management: a Binational Colorectal Cancer Audit study.

BACKGROUND: The COVID-19 pandemic has resulted in global disruptions to the delivery of healthcare. The national responses of Australia and New Zealand has resulted in unprecedented changes to the care of colorectal cancer patients, amongst others. This paper aims to determine the impact of COVID-19 on colorectal cancer diagnosis and management in Australia and New Zealand. METHODS: This is a multicentre retrospective cohort study using the prospectively maintained Binational Colorectal Cancer Audit (BCCA) registry. Data is contributed by over 200 surgeons in Australia and New Zealand. Patients receiving colorectal cancer surgery during the pandemic were compared to averages from the same period over the preceding 3 years. RESULTS: There were fewer operations in 2020 than the historical average. During April to June, patients were younger, more likely to have operations in public hospitals and more likely to have urgent or emergency operations. By October to December, proportionally less patients had Stage I disease, proportionally more had Stage II or III disease and there was no difference in Stage IV disease. Patients were less likely to have rectal cancer, were increasingly likely to have urgent or emergency surgery and more likely to have a stoma created. CONCLUSION: This study shows that the response to COVID-19 has had measurably negative effects on the diagnosis and management of colorectal cancer in two countries that have had significantly fewer COVID-19 cases than many other countries. The long-term effects on survival and recurrence are yet to be known, but could be significant.

Role of post-operative serum C-reactive protein levels as a predictor of complications in upper gastrointestinal surgery.

BACKGROUND: This study was undertaken to assess the value of C-reactive protein (CRP) in predicting infective complications after elective upper gastrointestinal surgery. METHODS: Demographic data, clinical outcomes and serial CRPs preoperatively to post-operative day (POD) 7 were collected for patients undergoing pancreatectomy, hepatectomy and oesophago-gastrectomy between 2005 and 2016. Areas under the curve (AUC) were used to evaluate diagnostic accuracy per day of measurement. RESULTS: Of the 249 patients, 63 (25.3%) developed infective complications and 25 (10%) developed severe infective complications (≥Clavien-Dindo Grade III). Patients with infective complications trended towards higher CRP levels on POD1-POD4 and had significantly higher CRP levels on POD5 (156 versus 114 mg/dL; P = 0.03), POD6 (146 versus 93 mg/dL; P < 0.01) and POD7 (135 versus 84.6 mg/dL; P < 0.01). CRP had the best diagnostic accuracy for severe infective complications on POD6 (AUC: 0.73) and POD7 (AUC: 0.63). A CRP cut-off of 120 mg/dL on POD6 had a negative predictive value of 96.1% and a CRP cut-off of 80 mg/dL on POD7 had a negative predictive value of 94.9%. CONCLUSION: CRP measurements can be used as a negative predictive marker of infective complications in the first post-operative week after major elective upper gastrointestinal surgery.

Peritoneal Cytokine Levels Can Predict Anastomotic Leak on the First Postoperative Day.

BACKGROUND: Accumulating evidence suggests that peritoneal cytokine concentrations may predict anastomotic leak after colorectal surgery, but previous studies have been underpowered. OBJECTIVE: We aimed to test this hypothesis by using a larger prospectively collected data set. DESIGN: This study is an analysis of prospectively collected data. SETTINGS: This study was conducted at 3 public hospitals in Auckland, New Zealand. PATIENTS: Patients undergoing colorectal surgery recruited as part of 3 previous randomized controlled trials were included. MAIN OUTCOME MEASURES: Data on peritoneal and plasma levels of interleukin-6, interleukin-8, interleukin-10, and tumor necrosis factor-α on day 1 after colorectal surgery were reanalyzed to evaluate their predictive value for clinically important anastomotic leak. Area under receiver operating characteristic curve analysis was performed. RESULTS: A total of 206 patients with complete cytokine data were included. The overall anastomotic leak rate was 8.3%. Concentration levels of peritoneal interleukin-6 and interleukin-10 on day 1 after colorectal surgery were predictive of anastomotic leak (area under receiver operating characteristic curve, 0.72 and 0.74; p = 0.006 and 0.004). Plasma cytokine levels of interleukin-6 were higher on day 1 after colorectal surgery in patients who had an anastomotic leak, but this was a poor predictor of anastomotic leak. Levels of other peritoneal and plasma cytokines were not predictive. LIMITATIONS: The study was not powered a priori for anastomotic leak prediction. Although the current data do suggest that peritoneal levels of interleukin-6 and interleukin-10 are predictive of leak, the discriminative value in clinical practice remains unclear. CONCLUSIONS: Peritoneal levels of interleukin-6 and interleukin-10 on day 1 after colorectal surgery can predict clinically important anastomotic leak.

Laparoscopic sleeve gastrectomy as a single-stage bariatric procedure.

BACKGROUND: Laparoscopic sleeve gastrectomy is increasingly being used as a stand-alone procedure in bariatric surgery, with medium-term follow-up data now emerging. We present our early experience in patients with a mean body mass index (BMI) in the super-obese range. METHODS: Review of prospectively collected data for the first 100 patients who underwent laparoscopic sleeve gastrectomy at Counties Manukau District Health Board between March 2007 and July 2008. RESULTS: One hundred patients were identified, with a mean age of 43 years (range, 20-60 years). Maori and Pacific Islanders made up 31% of the patient subset. Patients had a mean BMI of 50.3 kg/m(2) (range, 34.5-72.8 kg/m(2)). Forty-five patients were super-obese. The median hospital stay was 2 days (range, 1-7 days). Mean follow-up was 12.0 months (range, 0.9-23.3 months). Mean excess weight loss was 62.9% (range, 7.2-129.0%). Twenty-five percent of patients were diabetic and 45% of patients were hypertensive pre-operatively. Diabetics and hypertension resolved or improved in 72% and 60% of patients, respectively. There was a major complication rate of 7%, including three staple-line leaks (one requiring laparotomy), two staple-line bleeds (one requiring laparotomy) and one infected haematoma. There were no deaths. CONCLUSIONS: In this public hospital setting, laparoscopic sleeve gastrectomy has achieved satisfactory weight loss results with an acceptable complication rate in the medium-term.
