End to side circular stapled anastomosis during robotic-assisted Ivor Lewis minimally invasive esophagectomy (RAMIE)

Robotic-assisted minimally invasive esophagectomy (RAMIE) represents an established approach for the treatment of esophageal cancer. Aim of this study is to evaluate the feasibility and safety of our technique for performing the intrathoracic anastomosis during RAMIE.All the procedures were performed by the same surgeon using the same technique for performing the intrathoracic anastomosis. Intraoperative and postoperative outcomes were recorded. Postoperative complications were classified according to the Esophagectomy Complications Consensus Group (ECCG); the primary outcome was the evaluation of the feasibility and safety of our technique. From 2016 to 2021, 204 patients underwent Ivor Lewis RAMIE at our Center. Two patients (0.9%) were converted during the thoracic phase. The anastomosis was completed in all the other patients forming complete anastomotic rings. The median duration for the robotic-assisted thoracoscopic phase was 224 minutes. Twenty-two of the RAMIE-Ivor Lewis patients had an anastomotic leakage (10.3%). The overall 90-day postoperative mortality was 1.9%. The procedure resulted to be feasible and safe in our cohort of patients.

ENHANCED RECOVERY PATHWAYS (ERAS) IMPLEMENTATION IN MINIMALLY INVASIVE ESOPHAGECTOMY; AN EARLY EXPERIENCE

Objective: To evaluate the impact of enhanced recovery pathways (ERAS) on hospital stay and postoperative outcomes in patients undergoing minimally invasive esophagectomy in comparison to conventional pathway. Study Design: Quasi experimental study. Place and Duration of Study: Thoracic Surgery Department, Combined Military Hospital Rawalpindi Pakistan, from Jul 2018 to Mar 2020. Methodology: A total of 80 patients who underwent minimally invasive esophagectomy were divided in two groups. Group A underwent ERAS pathway and group B underwent conventional pathway. Both groups were compared for demographic characteristics, mean ICU stay, length of hospital stay, commencement of oral intake, and time of chest drain removal, readmission rates, postoperative morbidity and mortality. Results: There was no significant difference in age, gender and diagnostic indication among both groups. ERAS group was found to have shorter mean ICU stay (1.18 ± 0.55 vs 2.06 ± 1.10 days p<0.012), shorter hospital stay (7.50 ± 1.23 vs 11.6 ± 3.65 days, p<.001), earlier commencement of oral feeding (4.30 ± 1.41 vs 9.10 ± 4.26 days, p<0.001) and early removal of chest drains (3.22 ± vs 4.11 ± 1.52 p<0.001); when compared to conventional group. Overall morbidity in ERAS group was 50 (40%) versus 65% (81.25%) in conventional group. Mortality was same in both groups (2.5%). There was no readmission in ERAS group. Conclusion: ERAS in minimally invasive esophagectomy is safe and has positive impact on postoperative outcomes with marked reduction in overall morbidity in comparison to conventional regime. Results can be enhanced by ensuring better compliance to its.......

Stroke Volume Variation-Guided Goal-Directed Fluid Therapy Did Not Significantly Reduce the Incidence of Early Postoperative Complications in Elderly Patients Undergoing Minimally Invasive Esophagectomy: A Randomized Controlled Trial

Study Objective: This study aimed to investigate whether stroke volume variation (SVV)-guided goal-directed therapy (GDT) can improve postoperative outcomes in elderly patients undergoing minimally invasive esophagectomy (MIE) compared with conventional care.Design: A prospective, randomized, controlled study.Setting: A single tertiary care center with a study period from November 2017 to December 2018.Patients: Patients over 65 years old who were scheduled for elective MIE.Interventions: The GDT protocol included a baseline fluid supplement of 7 ml/kg/h Ringer's lactate solution and SVV optimization using colloid boluses assessed by pulse-contour analysis (PiCCO™). When SVV exceeded 11%, colloid was infused at a rate of 50 ml per minute; if SVV returned below 9% for at least 2 minutes, then colloid was stopped.Measurements: The primary outcome was the incidence of postoperative complications before discharge, as assessed using a predefined list, including postoperative anastomotic leakage, postoperative hoarseness, postoperative pulmonary complications, chylothorax, myocardial injury, and all-cause mortality.Main Results: Sixty-five patients were included in the analysis. The incidence of postoperative complications between groups was similar (GDT 36.4% vs. control 37.5%, P = 0.92). The total fluid volume was not significantly different between the two groups (2,192 ± 469 vs. 2,201 ± 337 ml, P = 0.92). Compared with those in the control group (n = 32), patients in the GDT group (n = 33) received more colloids intraoperatively (874 ± 369 vs. 270 ± 67 ml, P &lt;0.05) and less crystalloid fluid (1,318 ± 386 vs. 1,937 ± 334 ml, P &lt;0.05).Conclusion: The colloid-based SVV optimization during GDT did not significantly reduce the incidence of early postoperative complications after minimally invasive esophagectomy in elderly patients.Clinical Trial Number and Registry URL: ChiCTR-INR-17013352; http://www.chictr.org.cn/showproj.aspx?proj=22883

Operative Outcomes of Minimally Invasive Esophagectomy versus Open Esophagectomy for Resectable Esophageal Cancer

Background There is a recent rise in the incidence of esophageal carcinoma in India. Surgical resection with or without neoadjuvant chemoradiation is the current treatment modality of choice. Postoperative complications, especially pulmonary complications, affect many patients who undergo open esophagectomy for esophageal cancer. Minimally invasive esophagectomy (MIE) could reduce the pulmonary complications and reduce the postoperative stay. Methodology We performed a retrospective analysis of prospectively collected data of 114 patients with esophageal cancer in the department of surgical oncology at a tertiary cancer center in South India between January 2019 and March 2020. We included patients with resectable cancer of middle or lower third of the esophagus, and gastroesophageal junction tumors (Siewert I). MIE was performed in 27 patients and 78 patients underwent open esophagectomy (OE). The primary outcome measured was postoperative complications of Clavien–Dindo grade II or higher within 30 days. Other outcomes measured include overall mortality within 30 days, intraoperative complications, operative duration and the length of hospital stay. Results A postoperative complication rate of 18.5% was noted in the MIE group, compared with 41% in the OE group (p = 0.034). Pulmonary complications were noted in 7.4% in the MIE group compared to 25.6% in the OE group (p = 0.044). Postoperative mortality rates, intraoperative complications, and other nonpulmonary postoperative complications were almost similar with MIE as with open esophagectomy. Although the median operative time was more in the MIE group (260 minutes vs. 180 minutes; p < 0.0001), the median length of hospital stay was shorter in patients undergoing MIE (9 days vs. 12 days; p = 0.0001). Conclusions We found that MIE resulted in lower incidence of postoperative complications, especially pulmonary complications. Although, MIE was associated with prolonged operative duration, it resulted in shorter hospital stay.

P-OGC26 Learning curves in minimally invasive esophagectomy- a systematic review and evaluation of benchmarking parameters

Background Minimally invasive techniques are increasingly used in the treatment of esophageal cancer. The learning curve for minimally invasive oesophagectomy (MIO) is variable and can impact on patient outcomes. The aim of this study was to review the current evidence on learning curves in MIO and identify which parameters are used for benchmarking. Methods A search of the major reference databases (PubMed, Medline, Cochrane) was performed with no time limits up to February 2020. Results were screened in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies were included if an assessment of the learning curve was reported on, regardless of which (if any) statistical method was used. Results Twenty-nine studies comprising 3741 patients were included. Twenty-two studies reported on a combination of thoracoscopic, hybrid and total MIO, 6 studies reported robotic assisted MIO (RAMIE) alone and 1 study evaluated both RAMIE and thoracoscopic esophagectomies. Operating time was the most frequently used parameter to determine learning curve progression (23/39 studies), with number of resected lymph nodes, morbidity and blood loss also frequently used. Learning curves were found to plateau at 7-60 cases for thoracoscopic esophagectomy, 12-175 cases for total and thoracoscopic/hybrid esophagectomy and 9-85 cases for RAMIE. Conclusions Multiple parameters are employed to gauge MIO learning curve progression. However, there are no validated or approved sets of outcomes. Further work is required to determine the optimum parameters that should be utilised to ensure best patient outcomes and required length of proctoring.
