Correction to: Two years later: Is the SARS-CoV-2 pandemic still having an impact on emergency surgery? An international cross-sectional survey among WSES members

Background: The SARS-CoV-2 pandemic is still ongoing and a major challenge for health care services worldwide. In the first WSES COVID-19 emergency surgery survey, a strong negative impact on emergency surgery (ES) had been described already early in the pandemic situation. However, the knowledge is limited about current effects of the pandemic on patient flow through emergency rooms, daily routine and decision making in ES as well as their changes over time during the last two pandemic years. This second WSES COVID-19 emergency surgery survey investigates the impact of the SARS-CoV-2 pandemic on ES during the course of the pandemic. Methods: A web survey had been distributed to medical specialists in ES during a four-week period from January 2022, investigating the impact of the pandemic on patients and septic diseases both requiring ES, structural problems due to the pandemic and time-to-intervention in ES routine. Results: 367 collaborators from 59 countries responded to the survey. The majority indicated that the pandemic still significantly impacts on treatment and outcome of surgical emergency patients (83.1% and 78.5%, respectively). As reasons, the collaborators reported decreased case load in ES (44.7%), but patients presenting with more prolonged and severe diseases, especially concerning perforated appendicitis (62.1%) and diverticulitis (57.5%). Otherwise, approximately 50% of the participants still observe a delay in time-to-intervention in ES compared with the situation before the pandemic. Relevant causes leading to enlarged time-to-intervention in ES during the pandemic are persistent problems with in-hospital logistics, lacks in medical staff as well as operating room and intensive care capacities during the pandemic. This leads not only to the need for triage or transferring of ES patients to other hospitals, reported by 64.0% and 48.8% of the collaborators, respectively, but also to paradigm shifts in treatment modalities to non-operative approaches reported by 67.3% of the participants, especially in uncomplicated appendicitis, cholecystitis and multiple-recurrent diverticulitis. Conclusions: The SARS-CoV-2 pandemic still significantly impacts on care and outcome of patients in ES. Well-known problems with in-hospital logistics are not sufficiently resolved by now; however, medical staff shortages and reduced capacities have been dramatically aggravated over last two pandemic years

Assessing the feasibility of full robotic interaortocaval nodal dissection for locally advanced gastric cancer

BACKGROUND: The clinical value of super-extended lymph node dissection (D2(+) ) is still debated. This procedure has not been reported using the laparoscopic or robotic approach. Although this technique, in low-volume centres, could lead to an increased risk of morbidity, in high-volume centres morbidity and mortality are similar to those of the standard D2 lymphadenectomy. Robotic surgery could overcome the limitations of laparoscopic surgery, especially in the removal of posterior nodal stations. In this report we describe the feasibility of fully robotic interaortocaval lymphadenectomy, following similar steps to those of the traditional open approach. METHODS: The procedure was a total gastrectomy with oesophago-jejunal Roux-en-Y reconstruction in a 73 year-old male patient with clinically advanced (cT3) gastric adenocarcinoma, located in the lesser curvature (middle-upper third). The da Vinci® Si HD with a double-docking robot set-up was employed. RESULTS: The histological specimen examination showed a pT4aN3bM0, Borrmann type III, intestinal histotype, G3 gastric adenocarcinoma. No involvement of resection margins was found (R0 resection). The numbers of total harvested and positive nodes were 57 and 41, respectively; the number of harvested interaortocaval nodes was 14, and all of them were negative for tumour involvement. Operative time for lymphadenectomy was comparable with that of the traditional open approach. The postoperative period was uneventful and hospital stay was 11 days. CONCLUSIONS: Robotic-assisted interaortocaval lymphadenectomy is a feasible technique in high-volume centres for gastric cancer surgery, and should be considered in curative surgery for selected advanced cases, especially for the high-risk group of lymph node metastases in the posterior area

Re-evaluation of Mannheim prognostic index in perforative peritonitis: Prognostic role of advanced age. A prospective cohort study

Background: Peritonitis from perforation of abdominal viscera is associated with high mortality. In western countries individuals older than 65 years constitute a significant proportion of the population and intra abdominal infections are more challenging to manage in these aged patients. Methods: This prospective cohort study included 143 consecutive patients operated on for primary perforative peritonitis. The aim of the study was to assess the prognostic efficacy of Mannheim Peritonitis Index (MPI) in a population with a significant proportion of older patients and to substantiate advanced age as an independent prognostic factor. Patients' informations were collected both on hospitalization and after surgical exploration; severity of peritonitis was evaluated using the MPI. The prognostic value of MPI was compared to older age and other clinical variables. Results: The intra-hospital mortality was 25.2%. According to the MPI score, the ROC curve identified 21 as cut-off value with a sensitivity of 86% and a specificity of 59% in predicting the risk of death. MPI score and age over 80 years old resulted independent predictors of mortality at multivariate analysis. In the subgroup of patients with MPI score 21, the mortality rate was 46.4% for patients older than 80 years old and 38.3% for younger patients (p ¼ 0.07); in patients with MPI score <21, the mortality of those aged more than 80 years reached 33.3% compared to 3.4% for younger patients (p ¼ 0.001). Conclusions: Age older than 80 years is strongly related to major increase in mortality rates and should be taken into account together with the MPI score in planning the surgical approach and the post-operative care

Laparoscopy Versus Robotic Surgery for Colorectal Cancer: A Single-Center Initial Experience

Background Minimally invasive approach has gained interest in the treatment of patients with colorectal cancer. The purpose of this study is to analyze the differences between laparoscopy and robotics for colorectal cancer in terms of oncologic and clinical outcomes in an initial experience of a single center. Materials and Methods Clinico-pathological data of 100 patients surgically treated for colorectal cancer from March 2008 to April 2014 with laparoscopy and robotics were analyzed. The procedures were right colonic, left colonic, and rectal resections. A comparison between the laparoscopic and robotic resections was made and an analysis of the first and the last procedures in the 2 groups was performed. Results Forty-two patients underwent robotic resection and 58 underwent laparoscopic resection. The postoperative mortality was 1%. The number of harvested lymph nodes was higher in robotics. The conversion rate was 7.1% for robotics and 3.4% for laparoscopy. The operative time was lower in laparoscopy for all the procedures. No differences were found between the first and the last procedures in the 2 groups. Conclusions This initial experience has shown that robotic surgery for the treatment of colorectal adenocarcinoma is a feasible and safe procedure in terms of oncologic and clinical outcomes, although an appropriate learning curve is necessary. Further investigation is needed to demonstrate real advantages of robotics over laparoscopy

Robotic single docking total colectomy for ulcerative colitis: First experience with a novel technique

INTRODUCTION: We describe a novel technique that could aid the surgeon to perform a total proctocolectomy with a single docking position of the da Vinci Si HD System. METHODS: Patients were positioned in 20° Trendelenburg lithotomy split legs position. A 12-mm trocar was for camera and 3 more trocars were placed: two robotics on left and right flanks and one laparoscopic in left iliac fossa. The robot was docked between the legs of the patients. RESULTS: Four proctocolectomies were performed. Mean operative time was 235 min (range 215-255); mean blood loss was 100 cc (range 50-200). Median post-operative stay was 6 days. Overall morbidity was 75%, whereas major complications occurred in 25%. Post-operative mortality was null. CONCLUSIONS: The robotic single docking approach to perform total proctocolectomy for ulcerative colitis is a time-saving technique respect to the multiple docking approach
