Background: There is a rapidly growing literature available on right hemicolectomy comparing the short- and long-term outcomes of robotic right colectomy (RRC) to that of laparoscopic right colectomy (LRC). The aim of this meta-analysis is to revise current comparative literature systematically. Methods: A systematic review of comparative studies published between 2000 to 2021 in PubMed, Scopus and Embase was performed. The primary endpoint was postoperative morbidity, mortality and long-term oncological results. Secondary endpoints consist of blood loss, conversion rates, complications, time to first flatus, hospital stay and incisional hernia rate. Results: 25 of 322 studies were considered for data extraction. A total of 16,099 individual patients who underwent RRC (n = 1842) or LRC (n = 14,257) between 2002 and 2020 were identified. Operative time was significantly shorter in the LRC group (LRC 165.31 min ± 43.08 vs. RRC 207.38 min ± 189.13, MD: −42.01 (95% CI: −51.06−32.96), p < 0.001). Blood loss was significantly lower in the RRC group (LRC 63.57 ± 35.21 vs. RRC 53.62 ± 34.02, MD: 10.03 (95% CI: 1.61–18.45), p = 0.02) as well as conversion rate (LRC 1155/11,629 vs. RRC 94/1534, OR: 1.65 (1.28–2.13), p < 0.001) and hospital stay (LRC 6.15 ± 31.77 vs. RRC 5.31 ± 1.65, MD: 0.84 (95% CI: 0.29–1.38), p = 0.003). Oncological long-term results did not differ between both groups. Conclusion: The advantages of robotic colorectal procedures were clearly demonstrated. RRC can be regarded as safe and feasible. Most of the included studies were retrospective with a limited level of evidence. Further randomized trials would be suitable.

Purpose: Robotic assisted surgery is an alternative, fast evolving technique for performing colorectal surgery. The primary aim of this single center analysis is to compare elective laparoscopic and robotic sigmoid colectomies for diverticular disease on the extent of operative trauma and the costs. Methods: Retrospective analysis from our prospective clinical database to identify all consecutive patients aged ≥ 18 years who underwent elective minimally invasive left sided colectomy for diverticular disease from January 2016 until December 2020 at our tertiary referral institution. Results: In total, 83 patients (31 female and 52 male) with sigmoid diverticulitis underwent elective minimally invasive sigmoid colectomy, of which 42 underwent conventional laparoscopic surgery (LS) and 41 robotic assisted surgery (RS). The mean C-reactive protein difference between the preoperative and postoperative value was significantly lower in the robotic assisted group (4,03 mg/dL) than in the laparoscopic group (7.32 mg/dL) (p = 0.030). Similarly, the robotic´s hemoglobin difference was significantly lower (p = 0.039). The first postoperative bowel movement in the LS group occurred after a mean of 2.19 days, later than after a mean of 1.63 days in the RS group (p = 0.011). An overview of overall charge revealed significantly lower total costs per operation and postoperative hospital stay for the robotic approach, 6058 € vs. 6142 € (p = 0,014) not including the acquisition and maintenance costs for both systems. Conclusion: Robotic colon resection for diverticular disease is cost-effective and delivers reduced intraoperative trauma with significantly lower postoperative C-reactive protein and hemoglobin drift compared to conventional laparoscopy.

Background: Secondary resection rates in first-line chemotherapy trials for metastatic colorectal cancer (mCRC) remain below 15%, representing a clear contrast to reports by specialised surgical centres, where progressive liver, peritoneal-surface, and pulmonary surgery increased access to curative-intent treatment. We present a long-term evaluation of oncosurgical management in a single-centre, analysing the aggregate effect of gradual implementation of surgical subspecialties and systemic treatments on mCRC patients’ resection rates and prognosis. Methods: Patients with newly diagnosed mCRC from 2003 to 2014 were retrospectively categorised into palliative treatment (PAT) and curative intent surgery (CIS) and three time periods were analysed for treatment changes and factors associated with survival. Results: Four hundred-twenty patients were treated (PAT:250/CIS:170). Over time periods, the number of presenting patients remained consistent, whereas curative resection rates increased from 29% to 55%, facilitated by an increment of patients undergoing hepatectomy (21 to 35%), pulmonary surgery (6 to 17%), and peritonectomy/intraoperative chemotherapy (0 to 8%). Also, recently, significantly more multi-line systemic treatments were applied. The median survival markedly improved from 21.9 months (2003–2006; 95% confidence interval (CI) 17.3–26.5) to 36.5 months (2011–2014; 95% CI 26.6–46.4; p = 0.018). PAT was a significant factor of poor survival and diagnosis of mCRC in the latest time period was independently associated with a distinctly lower risk for palliative treatment (odds ratio 0.15). Conclusions: In modern eras of medical oncology, achieving appropriate resection rates through utilization of state-of-the-art oncological surgery by dedicated experts represents a cornerstone for long-term survival in mCRC.

Summary: Background: Some medical disciplines have reported a strong decrease of emergencies during the coronavirus disease 2019 (COVID-19) pandemic; however, the effect of the lockdown on general surgery emergencies remains unclear. Methods: This study is a retrospective, multicenter analysis of general surgery emergency operations performed during the period from 1 March to 15th 2020 lockdown and in the same time period of 2019 in three medical centers providing emergency surgical care to the area Salzburg-North, Austria. Results: In total 165 emergency surgeries were performed in the study period of 2020 compared to 287 in 2019. This is a significant decrease of 122 (42.5%) emergency surgeries during the COVID-19 lockdown (p = 0.005). The length of hospital stay was reduced to 3 days in 2020 compared to 4 in 2019. Appendectomy remained the most performed emergency surgery for both periods; however the number of surgeries was reduced to less than a half, with 72 cases in 2019 and 33 cases in 2020 (p = 0.118). Emergency colon surgery observed the strongest decrease of 75% from 17 cases in 2019 to 4 in 2020. In addition, the emergency abdominal wall hernia, cholecystectomies for acute cholecystitis, small surgeries and proctological emergencies recorded drops of 70%, 39%, 33% and 47% respectively. The strongest reduction in frequencies of emergency surgeries was reported from the designated COVID center in the examined region. Conclusions: Emergency general surgery is an essential service that continues to run under all circumstances. Our data show that COVID-19-related restrictions have resulted in a significant decrease in the utilization of acute surgical care.

Purpose: Sexual function is crucial for the quality of life and can be highly affected by preoperative therapy and surgery. The aim of this study was to identify potential risk factors for poor sexual function and quality of life. Methods: Female patients were asked to complete the Female Sexual Function Index (FSFI-6). Male patients were demanded to answer the International Index of Erectile Function (IIEF-5). Results: In total, 79 patients filled in the questionary, yielding a response rate of 41.57%. The proportion of women was represented by 32.91%, and the median age was 76.0 years (66.0–81.0). Sexual dysfunction appeared in 88.46% of female patients. Severe erectile dysfunction occurred in 52.83% of male patients. Univariate analysis showed female patients (OR: 0.17, 95%CI: 0.05–0.64, p = 0.01), older age (OR: 0.34, 95%CI 0.11–1.01, p = 0.05), tumor localization under 6cm from the anal verge (OR: 4.43, 95%CI: 1.44–13.67, p = 0.01) and extension of operation (APR and ISR) (OR: 0.13, 95%CI: 0.03–0.59, p = 0.01) as significant risk factors for poor outcome. Female patients (OR: 0.12, 95%CI: 0.03–0.62, p = 0.01) and tumors below 6 cm from the anal verge (OR: 4.64, 95%CI: 1.18–18.29, p = 0.03) were shown to be independent risk factors for sexual dysfunction after multimodal therapy in the multivariate analysis. Quality of life was only affected in the case of extensive surgery (p = 0.02). Conclusion: Higher Age, female sex, distal tumors and extensive surgery (APR, ISR) are revealed risk factors for SD in this study. Quality of life was only affected in the case of APR or ISR.

Background: The treatment of locally advanced rectal cancer (LARC) has steadily progressed over the past four decades, with recent focus shifting towards total neoadjuvant therapy (TNT). This survey aims to elucidate the perceived surgical challenges faced by Austrian colorectal surgeons performing total mesorectal excision (TME), focusing on the increased complexity and surgical difficulty introduced by intensified treatment regimens. Methods: A comprehensive survey was conducted among Austrian colorectal surgeons to explore various aspects of managing and performing TME following TNT. The survey included questions on the general management of LARC within their institutions and utilized a five-point Likert scale to assess the respondents’ perceptions and experiences regarding surgical precision and post-operative morbidity associated with TNT. Results: A total of 31 surgeons (54% response rate) completed the survey. Regarding multidisciplinary therapy preferences, 56% of respondents preferred conventional neoadjuvant therapy regimens, with 32% favoring chemoradiotherapy and 24% opting for short-course radiotherapy, while 31% chose TNT. The majority of respondents (65%) reported quality differences in tissue dissection during TME following TNT, with 57% experiencing difficulties in identifying tissue planes and 47% noting increased tissue fragility. Increased bleeding was reported by 32% of respondents. In cases of regrowth after a watch-and-wait approach, 64% observed quality changes in tissue dissection, and 47% noted tissue fragility. Conclusions: The survey results indicate that TNT impairs surgical precision due to changes in tissue quality and challenges in identifying surgical planes. Given the critical importance of surgical precision in achieving low local recurrence rates in mid-to-low LARC, these challenges could significantly impact patient outcomes. Further prospective studies are required to elucidate the extent of these effects.
