RESUMO
AIM: Minimally invasive surgery has been increasingly adopted for locally advanced colon cancer. However, evidence comparing robotic (RRC) versus laparoscopic right colectomy (LRC) for nonmetastatic pT4 cancers is lacking. METHODS: This was a multicentre propensity score-matched (PSM) study of a cohort of consecutive patients with pT4 right colon cancer treated with RRC or LRC. The two surgical approaches were compared in terms of R0, number of lymph nodes harvested, intra- and postoperative complication rates, overall (OS), and disease-free survival (DFS). RESULTS: Among a total of 200 patients, 39 RRC were compared with 78 PS-matched LRC patients. The R0 rate was similar between RRC and LRC (92.3% vs. 96.2%, respectively; p = 0.399), as was the odds of retrieving 12 or more lymph nodes (97.4% vs. 96.2%; p = 1). No significant difference was noted for the mean operating time (192.9 min vs. 198.3 min; p = 0.750). However, RRC was associated with fewer conversions to laparotomy (5.1% vs. 20.5%; p = 0.032), less blood loss (36.9 vs. 95.2 mL; p < 0.0001), fewer postoperative complications (17.9% vs. 41%; p = 0.013), a shorter time to flatus (2 vs. 2.8 days; p = 0.009), and a shorter hospital stay (6.4 vs. 9.5 days; p < 0.0001) compared with LRC. These results were confirmed even when converted procedures were excluded from the analysis. The 1-, 3- and 5-year OS (p = 0.757) and DFS (p = 0.321) did not significantly differ between RRC and LRC. CONCLUSION: Adequate oncological outcomes are observed for RRC and LRC performed for pT4 right colon cancer. However, RRC is associated with lower conversion rates and improved short-term postoperative outcomes.

AIM: Operation time (OT) is a key operational factor influencing surgical outcomes. The present study aimed to analyse whether OT impacts on short-term outcomes of minimally-invasive right colectomies by assessing the role of surgical approach (robotic [RRC] or laparoscopic right colectomy [LRC]), and type of ileocolic anastomosis (i.e., intracorporal [IA] or extra-corporal anastomosis [EA]). METHODS: This was a retrospective analysis of the Minimally-invasivE surgery for oncological Right ColectomY (MERCY) Study Group database, which included adult patients with nonmetastatic right colon adenocarcinoma operated on by oncological RRC or LRC between January 2014 and December 2020. Univariate and multivariate analyses were used. RESULTS: The study sample was composed of 1549 patients who were divided into three groups according to the OT quartiles: (1) First quartile, <135 min (n = 386); (2) Second and third quartiles, 135-199 min (n = 731); and (3) Fourth quartile ≥200 min (n = 432). The majority (62.7%) were LRC-EA, followed by LRC-IA (24.3%), RRC-IA (11.1%), and RRC-EA (1.9%). Independent predictors of an OT ≥ 200 min included male gender, age, obesity, diabetes, use of indocyanine green fluorescence, and IA confection. An OT ≥ 200 min was significantly associated with an increased risk of postoperative noninfective complications (AOR: 1.56; 95% CI: 1.15-2.13; p = 0.004), whereas the surgical approach and the type of anastomosis had no impact on postoperative morbidity. CONCLUSION: Prolonged OT is independently associated with increased odds of postoperative noninfective complications in oncological minimally-invasive right colectomy.

BACKGROUND: Botulinum toxin is an effective therapeutic option for chronic anal fissure. However, there is no evidence about treatment standardization and long-term follow-up. We aimed to evaluate the short- and long-term efficacy and safety of botulinum toxin compared to close lateral internal sphincterotomy, with a 5-year follow-up. METHODS: This was a prospective, controlled, single-center study conducted at University Hospital of Ferrara, Ferrara, Italy. The primary outcome was fissure healing at 1 month. Secondary outcomes were Quality-of-Life (QoL) at 1 month and after 5 years, and fissure recurrence at 6 months and 5 years. RESULTS: A total of 59 patients received botulinum toxin injection (Botox), and 32 underwent lateral internal sphincterotomy. At 1 month after treatments, postoperative pain decreased faster and significantly more in the Botox group (30 vs. 60 mm; P<0.001); fissure re-epithelization was observed in 59.4% of the surgical group compared to 25.4% of Botox (P=0.0001). Anal sphincter pressures decreased more in surgical group (P=0.044), although severe anal incontinence was present only in this subset (6.2%; P=0.041). Compared to surgery, patients who received Botox had higher satisfaction rates (P<0.001). Fissure recurrence at 6 months was more common in Botox than surgical group (16.9% vs. 3.2%, respectively; P=0.053). The overall healing rate improved in all patients and persisted at 12 months and 5 years in both groups with overall high patient satisfaction despite mild anal incontinence in 21.8% in the surgery group (P<0.05). CONCLUSIONS: Botox, rather than surgery, should be considered the first-line treatment for chronic anal fissure.

Background: The role of robotic surgery for gastrointestinal stromal tumor (GIST) resection remains unclear. This systematic review and meta-analysis aimed to investigate the outcomes of robotic versus laparoscopic surgery in patients requiring surgery for gastric GISTs. Methods: MEDLINE, EMBASE, and the Cochrane databases were searched from inception to September 4, 2023. Two independent reviewers conducted a systematic review of the literature to select all types of analytic studies comparing robotic versus laparoscopic surgery for GISTs and reporting intraoperative, postoperative, and/or pathological outcomes. Results: Overall, 4 retrospective studies were selected, including a total of 264 patients, specifically 111 (42%) in the robotic and 153 (58%) in the laparoscopic group. Robotic surgery was associated with longer operating time (+42.46 min; 95% confidence interval [CI]: 9.34, 75.58; P=0.01; I2: 85%) and reduced use of mechanical staplers (odds ratio [OR]: 0.05; 95%CI: 0.02, 0.11; P<0.00001; I2: 92%;) compared with laparoscopy. Although nonsignificant, conversion to open surgery was less frequently reported for robotic surgery (2.7%) than laparoscopy (5.2%) (OR: 0.59; 95%CI: 0.17, 2.03; P=0.4; I2: 0%). No difference was found for postoperative and oncological outcomes. Conclusions: Robotic surgery for gastric GISTs provides similar intraoperative, postoperative, and pathological outcomes to laparoscopy, despite longer operative time.

The introduction of new technologies in current digestive surgical practice is progressively reshaping the operating room, defining the fourth surgical revolution. The implementation of black boxes and control towers aims at streamlining workflow and reducing surgical error by early identification and analysis, while augmented reality and artificial intelligence augment surgeons' perceptual and technical skills by superimposing three-dimensional models to real-time surgical images. Moreover, the operating room architecture is transitioning toward an integrated digital environment to improve efficiency and, ultimately, patients' outcomes. This narrative review describes the most recent evidence regarding the role of these technologies in transforming the current digestive surgical practice, underlining their potential benefits and drawbacks in terms of efficiency and patients' outcomes, as an attempt to foresee the digestive surgical practice of tomorrow.
RESUMO
Iatrogenic urinary tract injury (IUTI) is a severe complication of emergency digestive surgery. It can lead to increased postoperative morbidity and mortality and have a long-term impact on the quality of life. The reported incidence of IUTIs varies greatly among the studies, ranging from 0.3 to 1.5%. Given the high volume of emergency digestive surgery performed worldwide, there is a need for well-defined and effective strategies to prevent and manage IUTIs. Currently, there is a lack of consensus regarding the prevention, detection, and management of IUTIs in the emergency setting. The present guidelines, promoted by the World Society of Emergency Surgery (WSES), were developed following a systematic review of the literature and an international expert panel discussion. The primary aim of these WSES guidelines is to provide evidence-based recommendations to support clinicians and surgeons in the prevention, detection, and management of IUTIs during emergency digestive surgery. The following key aspects were considered: (1) effectiveness of preventive interventions for IUTIs during emergency digestive surgery; (2) intra-operative detection of IUTIs and appropriate management strategies; (3) postoperative detection of IUTIs and appropriate management strategies and timing; and (4) effectiveness of antibiotic therapy (including type and duration) in case of IUTIs.

BACKGROUND: Robotics represents the most technologically advanced approach in minimally invasive surgery (MIS). Its application in general surgery has increased progressively, with some early experience reported in emergency settings. The present position paper, supported by the World Society of Emergency Surgery (WSES), aims to provide a systematic review of the literature to develop consensus statements about the potential use of robotics in emergency general surgery. METHODS: This position paper was conducted according to the WSES methodology. A steering committee was constituted to draft the position paper according to the literature review. An international expert panel then critically revised the manuscript. Each statement was voted through a web survey to reach a consensus. RESULTS: Ten studies (3 case reports, 3 case series, and 4 retrospective comparative cohort studies) have been published regarding the applications of robotics for emergency general surgery procedures. Due to the paucity and overall low quality of evidence, 6 statements are proposed as expert opinions. In general, the experts claim for a strict patient selection while approaching emergent general surgery procedures with robotics, eventually considering it for hemodynamically stable patients only. An emergency setting should not be seen as an absolute contraindication for robotic surgery if an adequate training of the operating surgical team is available. In such conditions, robotic surgery can be considered safe, feasible, and associated with surgical outcomes related to an MIS approach. However, there are some concerns regarding the adoption of robotic surgery for emergency surgeries associated with the following: (i) the availability and accessibility of the robotic platform for emergency units and during night shifts, (ii) expected longer operative times, and (iii) increased costs. Further research is necessary to investigate the role of robotic surgery in emergency settings and to explore the possibility of performing telementoring and telesurgery, which are particularly valuable in emergency situations. CONCLUSIONS: Many hospitals are currently equipped with a robotic surgical platform which needs to be implemented efficiently. The role of robotic surgery for emergency procedures remains under investigation. However, its use is expanding with a careful assessment of costs and timeliness of operations. The proposed statements should be seen as a preliminary guide for the surgical community stressing the need for reevaluation and update processes as evidence expands in the relevant literature.

Abstract Objective Transanal hemorrhoidal artery ligation with mucopexy (ligation anopexy [LA]) and open hemorrhoidectomy (OH) can both be performed under local anesthesia. The aim of the present study was to analyze the impact and the cost-effectiveness of performing these techniques in an ambulatory setting of an Italian academic center on the postoperative outcome. Methods A series of 122 consecutive patients with grades II and III hemorrhoidal disease undergoing ambulatory surgical treatment of hemorrhoids in 2015 to 2018 (group A) was comparedwith 122 patients operated at the same institution in the same period (group H) in a hospital setting. The primary outcome was the number of days required to return to work/daily activities. Secondary outcomes included postoperative pain and complications, costeffectiveness, patient satisfaction, and recurrence at 12 months. In group A, all the procedures were performed under local anesthesia with early discharge. In group H, the procedureswere performed under general or loco-regional anesthesia with hospital admission. Results The mean number of days required to return to work/daily activities was 8.4 ± 4.8 days in group A, compared with 12.5 ± 3 days in group H (p<0.001). The visual analog scale (VAS) pain score at 1 week, 2 and 3 weeks, and 1 month after surgery was lower for patients undergoing LA in the ambulatory setting (p<0.01). We observedmore postoperative complications in hospitalized (12.5%) than in ambulatory patients (7.5%) (p<0.001). The total mean direct costs per patient were significantly lower in the ambulatory setting versus the hospital stay group (351.3 versus 1,746 euros). Conclusion Implementing ambulatory surgery for hemorrhoids is feasible, safe, and cost-effective.
Resumo Objetivo A ligação transanal da artéria hemorroidária com mucopexia e a hemorroidectomia aberta (HA) podem ser realizadas em anestesia local. O objetivo do presente estudo foi analisar o impacto no resultado pós-operatório e a relação custo-eficácia da realização destas técnicas em ambiente ambulatorial de um centro acadêmico italiano no desfecho pós-operatório. Métodos Uma série de 122 pacientes consecutivos com patologia hemorroidária de graus II e III submetidos a cirurgia de hemorroidas em regime ambulatório de 2015 a 2018 (grupo A) foi comparada com 122 pacientes operados na mesma instituição no mesmo período (grupo H) por hospitalização. O desfecho primário foi o número de dias necessários para regressar ao trabalho/atividades diárias. Os desfechos secundários incluíram dor e complicações pós-operatórias, custo-eficácia, satisfação do paciente, e recidiva aos 12 meses. No grupo A, todos os procedimentos foram realizados em anestesia local. No grupo H, os procedimentos foram realizados em anestesia geral ou loco-regional. Resultados A espera média para o regresso ao trabalho foi de 8,4 ± 4,8 dias no grupo A em comparação com 12,5 ± 3 dias no grupo H (p<0,001). A pontuação na escala visual analógica (EVA) da dor 1 semana, 2 e 3 semanas, e 1 mês após a cirurgia foi mais baixa para os pacientes submetidos a cirurgia de ligadura com anopexia em ambiente ambulatorial (p<0,01). Observamosmais complicações pós-operatórias empacientes hospitalizados (12,5%) do que em pacientes ambulatórios (7,5%) (p<0,001). Os custos diretosmédios totais por paciente foram mais baixos em ambiente ambulatório do que no grupo de hospitalização (351,3 contra 1.746 euros). Conclusão A implementação da cirurgia ambulatória para hemorroidas é possível, segura e rentável.
