Purpose: As part of the wide adoption of minimally invasive surgery, intracorporeal anastomosis is becoming increasingly common. The benefits of minimally invasive versus open right colectomy are well known although the additional benefits of an intracorporeal anastomosis, performed laparoscopically or robotically, are unclear. The aim of this study was to assess the current literature comparing intracorporeal and extracorporeal anastomosis in the setting of laparoscopic and robotic-assisted right colectomy. Methods: A systematic review and meta-analysis was conducted according to PRISMA and AMSTAR methods. Studies included were randomized controlled trials and prospective or retrospective cohort studies, between January 1 2010 and July 1 2021, comparing intracorporeal and extracorporeal anastomosis with laparoscopic and robotic approaches. Four groups were identified: laparoscopic extracorporeal anastomosis (L-ECA), laparoscopic intracorporeal anastomosis (L-ICA), robotic extracorporeal anastomosis (R-ECA), and robotic intracorporeal anastomosis (R-ICA). Operative time, rate of conversion to an open procedure, surgical site infection, reoperation within 30 days, postoperative complications within 30 days, and length of hospital stay were assessed. Results: Twenty-one retrospective cohort studies were included in the final analysis. R-ICA and R-ECA had comparable operative times, but a robotic approach required more time than laparoscopic (68 min longer, p < 0.00001). Conversion to open surgery was 55% less likely in the R-ICA group vs. L-ICA, and up to 94% less likely in the R-ICA group in comparison to the R-ECA group. Length of hospital stay was shorter for R-ICA by a half day vs. R-ECA, and up to 1 day less vs. L-ECA. There were no differences in postoperative complications, reoperations, or surgical site infections, regardless of approach. However, the included studies all had high risks of bias due to confounding variables and patient selection. Conclusion: Robotic-assisted right colectomy with intracorporeal anastomosis was associated with shorter length of hospitalization and decreased rate of conversion to open surgery, compared to either laparoscopic or extracorporeal robotic approaches. Prospective studies are needed to better understand the true impact of robotic approach and intracorporeal anastomosis in right colectomy. [ABSTRACT FROM AUTHOR]

Background: Femoral intramedullary nailing is traditionally performed with the patient supine on a fracture table. We aimed to describe a case series of femoral intramedullary nailing for fracture in the lateral position, with discussion of the operative technique. Methods: A retrospective analysis identified 52 patients who underwent femoral intramedullary nailing performed in a lateral position without traction over a 5-year period at a single level 1 trauma center. Medical records were reviewed for demographics, blood loss including need for transfusion, operative duration, complications, length of stay, fracture union, re-operation and death. Results: There were 24 subtrochanteric, 16 peri-trochanteric and 12 diaphyseal femoral fractures. Mean operative time was 136.2 ± 101.4 min with a mean estimated blood loss of 372.5 ± 349.6 ml. Seventeen patients required blood transfusion. Mean length of stay was 10.3 ± 8.1 days. There were 3 (5.8%) surgical (compartment syndrome, infection and retained drain) and 12 (23.1%) medical complications, with a 30-day mortality rate of 3.8% (2). Mean follow-up was 9.9 ± 8.7 months. The union rate was 94.2% (49) and 3.8% (2) patients required revision fixation (hardware exchange for irritation and exchange nailing for non-union). Discharge destination was home, rehabilitation center and specialized nursing facility in 21 (40.4%), 16 (30.8%) and 15 (28.8%) patients, respectively. Discussion and conclusion: Femoral intramedullary nailing in the lateral decubitus position is a useful technique of managing peri-trochanteric, subtrochanteric and diaphyseal femoral fractures. We describe a known technique with technical tips, which has distinct advantages over traditional supine positioning especially in certain patient and fracture types. In addition, operative times, blood loss, length of stay, revision and outcomes were comparable to the literature. [ABSTRACT FROM AUTHOR]

Purpose: The neonatal period is the most vulnerable period for a child. There is a paucity of data on the burden of neonatal surgical disease in our setting. The aim of this study was to describe the frequency with which index neonatal surgical conditions are seen within our setting and to document the 30-day outcome of these patients. Methods: This was a single-centre prospective observational study in which all neonates with paediatric surgical pathology referred to the paediatric surgical unit with a corrected gestational age of 28 days were included. Results: Necrotising enterocolitis was the most frequent reason for referral to the paediatric surgical unit (n = 68, 34.34%). Gastroschisis was the most frequent congenital anomaly referred (n = 20, 10.10%). The overall morbidity was 57.58%. Surgical complications contributed to 18.51% of morbidities. The development of gram negative nosocomial sepsis was the most frequent cause of morbidity (n = 98, 50.78%). Mortality at 30 days was 21.74% (n = 40). Sepsis contributed to mortality in 35 patients (87.5%), 16 of which had gram negative sepsis. Conclusion: Gram-negative sepsis was a major contributing factor in the development of morbidity and mortality in our cohort. Prevention and improvement in infection control are imperative if we are to improve outcomes in our surgical neonates. [ABSTRACT FROM AUTHOR]

Vascular access for renal dialysis is a lifeline for about 120 000 individuals in the United States. Stethoscope auscultation of vascular sounds has some utility in the assessment of access patency, yet can be highly skill-dependent. The objective of the study was to identify acoustic parameters that are related to changes in vascular access patency. The underlying hypothesis is that stenoses of haemodialysis access vessels or grafts cause vascular sound changes that are detectable using computerised data acquisition and analysis. Eleven patients participated in the study. Their vascular sounds were recorded before and after angiography, which was accompanied by angioplasty in most patients. The sounds were acquired using two electronic stethoscopes and then digitised and analysed on a personal computer. Vessel stenosis changes were found to be associated with changes in acoustic amplitude and/or spectral energy distribution. Certain acoustic parameters correlated well (correlation coefficient = 0.98, p < 0.0001) with the change in the degree of stenosis, suggesting that stenosis severity may be predictable from these parameters. Parameters also appeared to be sensitive to modest diameter changes (> 20%), (p < 0.005, Wilcoxon rank sum test). These results suggest that computerised analysis of vascular sounds may be useful in vessel patency surveillance. Further testing using longitudinal studies may be warranted. [ABSTRACT FROM AUTHOR]
