RESUMO
OBJECTIVES: To assess the impact of the learning curve (LC) on perioperative and long-term functional outcomes of a consecutive single-centre series of robot-assisted radical cystectomy with Padua intracorporeal orthotopic neobladder. PATIENTS AND METHODS: Patients treated between 2013 and 2022 were included, with ≥1 year of follow-up. The entire cohort was divided in tertiles. Categorical and continuous variables were compared. Joinpoint regression analysis was used to identify significant changes over the decade in linear slope of the 1-year day- and night-time continence. Uni- and multivariable Cox regression analyses identified predictors of day- and night-time continence recovery. Day-time continence was defined as 'totally dry' (no pads), night-time continence as pad wetness ≤50 mL (one safety pad). RESULTS: Overall, 200 patients were included. The mean hospital stay (P = 0.002) and 30-day complications (P = 0.04) significantly reduced over time; the LC significantly impacted on Trifecta achievement (P < 0.001). The 1-year day- and night-time continence probabilities displayed a significant improving trend (day-time continence annual average percentage change [AAPC] 11.45%, P < 0.001; night-time continence AAPC 10.05%, P = 0.009). The LC was an independent predictor of day- (hazard ratio [HR] 1.008; P < 0.001) and night-time continence (HR 1.004; P = 0.03) over time. CONCLUSION: Patients at the beginning of the LC had significantly longer hospitalisations, more postoperative complications, and lower Trifecta rates. At the 10-year analyses, we observed a significant improving trend for both the 1-year day- and night-time continence probabilities, highlighting the crucial role of the LC. However, we are unable to assess the case volume needed to achieve a plateau in terms of day- and night-time continence rates.

AIM: The aim of this work was to compare lymph node (LN) yield in patients operated on for right colon cancer (RCC) using a laparoscopic approach between those receiving an intracorporeal (ICA) or extracorporeal anastomosis (ECA). METHOD: This is a retrospective multicentre study involving patients operated on for RCC in nine tertiary referral centres in Latin America during a 2-year period. The main comparative outcome between groups was the number of LNs harvested between groups. RESULTS: The study included 416 patients, 261 (62.7%) in the ECA group and 155 (37.3%) in the ICA group. Patients in the ECA group were elderly (66 vs. 61 years, p < 0.001). Patients receiving an ICA achieved a significantly higher LN yield than those receiving an ECA (24 vs. 18, p < 0.001). This group also had a lower percentage of patients achieving a substandard LN yield (<12 LNs) (10% vs. 24.8%, p = 0.001) and more patients achieving a high number of harvested LNs (>32 LNs) (15.5% vs. 8.3%, p = 0.039). In the multivariate analysis, ICA was independently related to the primary outcome (LN yield) (OR 3.28, p = 0.027, 95% CI 1.14-9.38). CONCLUSION: In this retrospective study, patients operated on for RCC who received an ICA achieved a higher LN yield. Further studies are needed to reconfirm these findings, and also to find an explanation for these results.

AIM: Natural orifice specimen extraction (NOSE) in left-sided colorectal surgery requires application of the circular stapler anvil to the proximal bowel without exteriorization through an additional abdominal incision. We describe an intracorporeal method to secure the stapler anvil, termed the intracorporeal antimesenteric ancillary trocar (IAAT) technique. METHOD: The ancillary trocar is attached to the stapler anvil before introduction into the abdominal cavity through the anal or vaginal orifice. The colon is incised before the trocar spike is brought out through the antimesenteric surface 3-4 cm within the cut edge. A linear stapler is used to seal the bowel end. The ancillary trocar is detached and retrieved via the NOSE conduit. Following the NOSE procedure, a side-to-end colorectal anastomosis is performed with the transanal circular stapler. RESULTS: Ten consecutive patients underwent elective left-sided colorectal resection with IAAT for NOSE (seven transanal, three transvaginal) from January to June 2023. Median age and body mass index were 66 (range 47-74) years and 24.3 (range 17.9-30.8) kg/m2 respectively. Two (20%) patients underwent sigmoid colectomy for sigmoid volvulus while eight (80%) underwent anterior resection for colorectal cancer. Median operating time, operative blood loss and postoperative length of hospital stay were 170 (range 140-240) min, 20 (range 10-40) mL and 1 (range 1-3) day respectively. There were no postoperative complications, readmissions or reoperations. Median follow-up duration was 3 (range 1-6) months. CONCLUSION: The IAAT double-stapling side-to-end anastomotic technique is safe and feasible for patients undergoing left-sided colorectal resection with NOSE, resulting in good outcomes.

AIM: Creation of an overlapped anastomosis using handsewn sutures for common enterotomy is very popular in robotic right colectomy (RRC) with intracorpareal anastomosis (IA). The aim of this study is to present a simple method for constructing a sutureless overlapped anastomosis using a 60 mm linear stapler with a reinforced bioabsorbable material in RRC with IA. METHOD: The distal ileum and proximal colon were put in overlapping positions. Enterotomies were created 2 cm proximal to the ileal stump and 8 cm distal to the colonic stump on the antimesenteric side. Subsequently, a 60 mm linear stapler with a reinforced bioabsorbable material was inserted into each lumen and fired. Finally, the bowel was elevated while holding the bioabsorbable material, and the common enterotomy was grasped with the robotic instrument in the middle and closed using a linear stapler with a reinforced bioabsorbable material. RESULTS: This technique was applied to 10 patients with tumours of the caecum, ascending colon, or transverse colon. The median operating time, anastomosis construction time, blood loss, and postoperative stay were 281 min (range 228-459 min), 12 min (range 11-17 min), 10 mL (range 0-110 mL), and 10 days (range 8-15 days), respectively. No adverse intraoperative events were observed. Postoperatively, one patient developed chylous ascites, but there were no other complications. CONCLUSION: The simple technique for constructing a sutureless overlapped anastomosis using a 60 mm linear stapler with a reinforced bioabsorbable material in robotic right colectomy with intracorporeal anastomosis appears to be safe and feasible.

INTRODUCTION: We introduced the robotic NICE procedure for left-sided colorectal resection in 2018 in which the entire procedure is performed without loss of pneumoperitoneum and without an abdominal wall incision by performing natural orifice-assisted transrectal extraction of the specimen and intracorporeal anastomosis. We compare the results of the NICE procedure versus conventional laparoscopic resection, which was our standard approach prior to 2018. METHODS: A matched pair case-control study compared patients following the NICE procedure versus those who underwent laparoscopic left-sided colorectal resection with conventional extracorporeal-assisted technique. Cases were performed at an Academic Medical Center and recorded in a prospective database to analyze perioperative outcomes. RESULTS: From a total cohort of 352 patients, 83 were matched in each group. When comparing the NICE procedure vs. the Extracorporeal-Assisted laparoscopic group, there were no significant differences in age (58.5 vs. 59.3 years old), sex (47 vs. 42 Female), body mass index (27.4 vs. 27.5 kg/m2), ASA, diagnosis, or type of surgery. Operative time (198.8 vs. 197.7 min), blood loss (56.0 vs. 53.3 ml), intraoperative complications (0.0% vs. 0.0%), and conversion rates (0.0% vs. 0.0%) were similar in both groups. The NICE procedure was associated with significantly earlier return of bowel function (40.7 vs. 23.6 h), shorter length of stay (3.1 vs. 2.2 days), and lower total opioid use (94.6 vs. 70.5 morphine milligram equivalents). Overall, there were no differences in postoperative abscess formation, complications, readmission, or reoperation rates. CONCLUSION: When compared to conventional laparoscopic resection, the NICE procedure is associated with short-term benefits including earlier recovery and less opioid use without increased operative time or increased risk of complications. Multicenter studies are recommended to validate benefits and limitations of this technique.

BACKGROUND: Intracorporeal mechanical gastrogastrostomy (IMG) techniques have recently been developed and their short-term safety was presented in their initial evaluation. However, whether they are comparable to extracorporeal hand-sewing gastrogastrostomy (EHG) remains unclear. The aim of the study is to establish the safety of IMG in totally laparoscopic pylorus-preserving gastrectomy (TLPPG) compared to EHG in laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG). METHODS: We retrospectively analyzed the short-term outcomes of patients with middle-third early gastric cancer who underwent LAPPG or TLPPG between 2005 and 2022. The primary objective of this study was to evaluate the non-inferiority of IMG to EHG in terms of safety, with the primary endpoint being the risk difference in anastomosis-related complications (ARCs). The sample size required to achieve a statistical power of 80% for the non-inferiority test was 971 with a one-sided alpha level of 5% and non-inferiority of 5%. RESULTS: The analysis included a total of 1,021 patients who underwent LAPPG or TLPPG during the study period. Among them, 488 patients underwent EHG, while 533 underwent IMG. The incidences of ARCs were 11.3% and 11.4% in EHG and IMG, respectively. The observed difference in incidence was 0.0017 (90% confidence interval - 0.0313 to 0.0345), which statistically demonstrated the non-inferiority of IMG to EHG in the incidence of ARCs. Among other complications, the incidence of wound infection in IMG was lower than that in EHG. CONCLUSION: IMG is safe regarding ARCs compared with EHG. These results will encourage surgeons to introduce IMG for patients with early middle gastric cancer.

INTRODUCTION: Either extracorporeal anastomosis (EA) or intracorporeal anastomosis (IA) could be selected for digestive reconstruction in laparoscopic right hemicolectomy (LRH). However, whether LRH with IA is feasible and beneficial for overweight right-side colon cancer (RCC) is unclear. This study aims to investigate the feasibility and advantage of IA in LRH for overweight RCC. METHODS: Forty-eight consecutive overweight RCC patients undergoing LRH with IA were matched with 48 consecutive cases undergoing LRH with EA. Both clinical and surgical data were collected and analyzed. RESULTS: The incidence of postoperative complications was 20.8% (10/48) in the EA group and 14.6% (7/48) in the IA group respectively, with no statistical difference. Compared to the EA group, patients in the IA group revealed faster gas (40.2 + 7.8 h vs. 45.6 + 7.9 h, P = 0.001) and stool discharge (4.0 + 1.2 d vs. 4.5 + 1.1 d, P = 0.040), shorter assisted incision (5.3 + 1.3 cm vs. 7.5 + 1.2 cm, P = 0.000), and less analgesic used (3.3 + 1.3 d vs. 4.0 + 1.3 d, P = 0.012). There were no significant differences in operation time, blood loss, or postoperative hospital stays. In the IA group, the first one third of cases presented longer operation time (228.4 + 29.3 min) compared to the middle (191.0 + 35.0 min, P = 0.003) and the last one third of patients (182.2 + 20.7 min, P = 0.000). CONCLUSION: LRH with IA is feasible and safe for overweight RCC, with faster bowel function recovery and less pain. Accumulation of certain cases of LRH with IA will facilitate surgical procedures and reduce operation time.

PURPOSE: Performing intracorporeal anastomoses in minimally invasive colon surgery appears to provide better short-term outcomes for patients with colon cancer. The aim of the study is to compare surgical aspects and short-term outcomes between intracorporeal and extracorporeal techniques in left colectomies with both laparoscopic and robotic approaches and evaluate advantages and disadvantages of intracorporeal anastomosis according to IDEAL framework (Exploration, stage 2b). METHODS: This is a single center, ambispective cohort study comparing total intracorporeal anastomosis (TIA) and standard surgery with extracorporeal anastomosis (EA). Patients with colon cancer treated by left colectomy, sigmoidectomy and high anterior resection by total intracorporeal anastomosis between May 2020 and January 2023 without exclusion criteria were prospectively included in a standardized database. Short-term outcomes in the group undergoing TIA were compared with a historical EA cohort. The main assessment outcomes were intraoperative complications, postoperative morbidity according to the Clavien-Dindo scale and the comparison of pathological. We conducted a preliminary comparative study within the TIA group between approaches, a primary analysis between the two anastomotic techniques, and a propensity score matched analysis including only the laparoscopic approach, between both anastomotic techniques. RESULTS: Two hundred and forty-six patients were included: 103 who underwent TIA, 35 of them with laparoscopic approach and 68 with robotic approach, and a comparison group comprising another 103 eligible consecutive patients who underwent laparoscopic EA. There were no statistically significant differences between the two groups in terms of demographic variables. No statistically significant differences were observed in anastomotic dehiscence. Intraoperative complications are fewer in the TIA group, with a higher C-Reactive Protein levels. Relevant anastomotic bleeding and the number of retrieved lymph nodes were higher in EA group. Nevertheless, no differences were observed in terms of overall morbidity. CONCLUSION: Minimally invasive left colectomy with intracorporeal resection and anastomosis is technically feasible and safe suing either a laparoscopic or a robotic approach. Clinical data from this cohort demonstrate outcomes comparable to those achieved through the conventional EA procedure in relation to postoperative morbidity and oncological efficacy, with indications suggesting that the utilization of robotic-assisted techniques may play a contributing role in enhancing overall treatment outcomes.

PURPOSE: The surgical approach to bowel endometriosis is still unclear. The aim of the study is to compare TICA to conventional specimen extractions and extra-abdominal insertion of the anvil in terms of both complications and functional outcomes. METHODS: This is a single-center, observational, retrospective study conducted enrolling symptomatic women underwent laparoscopic excision of deep endometriosis with segmental bowel resection between September 2019 and June 2022. Women who underwent TICA were compared to classical technique (CT) in terms of intra- and postoperative complications, moreover, functional outcomes relating to the pelvic organs were assessed using validated questionnaires [Knowles-Eccersley-Scott-Symptom (KESS) questionnaire and Gastro-Intestinal Quality of Life Index (GIQLI)] for bowel function. Pain symptoms were assessed using Visual Analogue Scale (VAS) scores. RESULTS: The sample included 64 women. TICA was performed on 31.2% (n = 20) of the women, whereas CT was used on 68.8% (n = 44). None of the patients experienced rectovaginal, vesicovaginal, ureteral or vesical fistula, or ureteral stenosis and uroperitoneum, and in no cases was it necessary to reoperate. Regarding the two surgical approaches, no significant difference was observed in terms of complications. As concerns pain symptoms at 6-month follow-up evaluations on stratified data, except for dysuria, all VAS scales reported showed significant reductions between median values, for both surgery interventions. As well, significant improvements were further observed in KESS scores and overall GIQLI. Only the GIQLI evaluation was significantly smaller in the TICA group compared to CT after the 6-month follow-up. CONCLUSIONS: We did not find any significant differences in terms of intra- or post-operative complications compared TICA and CT, but only a slight improvement in the Gastro-Intestinal Quality of Life Index in patients who underwent the CT compared to the TICA technique.

PURPOSE: The aim of this study was to present our initial experience and prove the feasibility of total intracorporeal laparoscopic ileal ureter replacement (TILIUR) in a single position for ureteral stricture based on membrane anatomy. MATERIALS AND METHODS: Between January 2021 and April 2023, six patients underwent TILIUR in a single position for ureteral strictures based on membrane anatomy. All patients with a past medical history underwent radical hysterectomy with bilateral pelvic lymph node dissection as well as extensive ureteral stricture due to radiotherapy. The procedure is performed completely laparoscopically. Dissection of the digestive system as well as ureteral stricture or renal pelvis is based on membrane anatomy. The surgery is performed in a single position. RESULTS: TILIUR in a single position for ureteral stricture based on membrane anatomy was successfully performed without open conversion in all patients. Among the 6 patients, 3 patients underwent combined ileal ureter replacement (IUR) and abdominal wall ostomy, 2 underwent unilateral IUR, and 1 underwent bilateral IUR. The mean length of the ileal substitution was 22.83 cm (range: 15-28). The average operative time was 458 ± 72.77 min (range 385-575 min), and the average intraoperative blood loss was 158 mL (range 50-400 mL). The median postoperative hospital stay was 15.1 d (range: 8-32). The median duration of postoperative follow-up was 15 months (range: 3-29 months). The success rate was 100%. CONCLUSIONS: TILIUR in a single position may be a promising option for ureteral stricture based on membrane anatomy in selected patients. Moreover, it has a positive effect on patients with renal insufficiency and urinary incontinence. Although IUR is difficult and risky, proficient surgeons can perform the procedure safely and effectively.

Complete mesocolic excision (CME) with D3 lymphadenectomy for colon cancer has been shown to improve overall as well as disease-free survival compared to conventional right hemicolectomy. Performing a laparoscopic CME/D3 right hemicolectomy with intracorporeal anastomosis (ICA) can be technically demanding even for experienced operators. Here, we present a systematic, standardized approach to the surgery.

BACKGROUND: We aimed to compare outcomes and cost effectiveness of extra-corporeal anastomosis (ECA) versus intra-corporeal anastomosis (ICA) for laparoscopic right hemicolectomy using the National Surgical Quality Improvement Programme data. METHODS: Patients who underwent elective laparoscopic right hemicolectomy for colon cancer from January 2018 to December 2022 were identified. Non-cancer diagnoses, emergency procedures or synchronous resection of other organs were excluded. Surgical characteristics, peri-operative outcomes, long-term survival and hospitalisation costs were compared. Incremental cost-effectiveness ratio (ICER) was used to evaluate cost-effectiveness. RESULTS: A total of 223 patients (175 ECA, 48 ICA) were included in the analysis. Both cohorts exhibited comparable baseline patient, comorbidity, and tumour characteristics. Distribution of pathological TMN stage, tumour largest dimension, total lymph node harvest and resection margin lengths were statistically similar. ICA was associated with a longer median operative duration compared with ECA (255 min vs. 220 min, P < 0.001). There was a quicker time to gastrointestinal recovery, with a shorter median hospital stay in the ICA group (4.0 versus 5.0 days, P = 0.001). Overall complication rates were comparable. ICA was associated with a higher surgical procedure cost (£6301.57 versus £4998.52, P < 0.001), but lower costs for ward accommodation (£1679.05 versus £2420.15, P = 0.001) and treatment (£3774.55 versus £4895.14, P = 0.009), with a 4.5% reduced overall cost compared with ECA. The ICER of -£3323.58 showed ICA to be more cost effective than ECA, across a range of willingness-to-pay thresholds. CONCLUSION: ICA in laparoscopic right hemicolectomy is associated with quicker post-operative recovery and may be more cost effective compared with ECA, despite increased operative costs.

Background and Objectives: Laparoscopic right hemicolectomy (LRHC) is commonly performed for patients with colon cancer, selecting between intracorporeal anastomosis (ICA) or extracorporeal anastomosis (ECA). However, the impact of ICA versus ECA on patient outcomes remains debatable. The varying levels of experience among surgeons may influence the outcomes. Therefore, this study sought to compare the short- and long-term outcomes of LRHC using ICA versus ECA. Materials and Methods: This retrospective study extracted patient data from the medical records database of Changhua Christian Hospital, Taiwan, from 2017 to 2020. Patients with colon cancer who underwent LRHC with either ICA or ECA were included. Primary outcomes were post-surgical outcomes and secondary outcomes were recurrence rate, overall survival (OS), and cancer-specific survival (CSS). Between-group differences were compared using chi-square, t-tests, and Fisher's exact tests and Mann-Whitney U tests. Associations between study variables, OS, and CSS were determined using Cox analyses. Results: Data of 240 patients (61 of ICA and 179 of ECA) with a mean age of 65.0 years and median follow-up of 49.3 months were collected. No recognized difference was found in patient characteristics between these two groups. The ICA group had a significantly shorter operation duration (median (IQR): 120 (110-155) vs. 150 (130-180) min) and less blood loss (median (IQR): 30 (10-30) vs. 30 (30-50) mL) than the ECA group (p < 0.001). No significant differences were found in 30-day readmission (ICA vs. ECA: 1.6% vs. 2.2%, p > 0.999) or recurrence (18.0% vs. 13.4%, p = 0.377) between the two groups. Multivariable analyses revealed no significant differences in OS (adjusted hazard ratio (aHR): 0.65; 95% confidence interval (CI): 0.25-1.44) or CSS (adjusted sub-hazard ratio (aSHR): 0.41, 95% CI: 0.10-1.66) between groups. Conclusions: Both ICA and ECA in LRHC for colon cancer had similar outcomes without statistically significant differences in post-surgical complications, 30-day readmission rates, recurrence rate, and long-term survival outcomes. However, ICA may offer two advantages in terms of a shorter operative duration and reduced blood loss.

BACKGROUND: Esophagojejunostomy after minimally invasive total gastrectomy (MITG) for gastric cancer (GC) is technically challenging. Failure of the esophagojejunal anastomosis can lead to significant morbidity, leading to short- and long-term quality of life (QoL) impairment or mortality. The optimal reconstruction method following MITG remains controversial. We evaluated outcomes of minimally invasive esophagojejunostomy after laparoscopic or robotic total gastrectomies. METHODS: We retrospectively reviewed MITG patients between 2015 and 2020 at two high-volume centers in China and the United States. Eligible patients were divided into groups by different reconstruction methods. We compared clinicopathologic characteristics, postoperative outcomes, including complication rates, overall survival rate (OS), disease-free survival rate (DFS), and patient-reported QoL. RESULTS: GC patients (n = 105) were divided into intracorporeal esophagojejunostomy (IEJ, n = 60) and extracorporeal esophagojejunostomy (EEJ, n = 45) groups. EEJ had higher incidence of wound infection (8.3% vs 13.3%, P = 0.044) and pneumonia (21.7% vs 40.0%, P = 0.042) than IEJ. The linear stapler (LS) group was inferior to the circular stapler (CS) group in reflux [50.0 (11.1-77.8) vs 44.4 (0.0-66.7), P = 0.041] and diarrhea [33.3 (0.0-66.7) vs 0.0 (0.0-66.7), P = 0.045] while LS was better than CS for dysphagia [22.2 (0.0-33.3) vs 11.1 (0.0-33.3), P = 0.049] and eating restrictions [33.3 (16.7-58.3) vs 41.7 (16.7-66.7), P = 0.029] at 1 year. OS and DFS did not differ significantly between LS and CS. CONCLUSIONS: IEJ anastomosis generated better results than EEJ. LS was associated with a better patient eating experience, but more diarrhea and reflux compared with CS. Clinical and patient-reported outcomes show the superiority of IEJ with the LS reconstruction method in MITG for GC.

OBJECTIVE: To provide the first clinical validation of the European Association of Urology Robotic Urology Section (ERUS) curriculum for training in robot-assisted radical cystectomy with intracorporeal urinary diversion (iRARC). PATIENTS AND METHODS: The ERUS proposed a structured curriculum, divided into 11 steps, to train novice surgeons and help overcome the steep learning curve associated with iRARC. In this study, one trainee completed the curriculum under the mentorship of an expert. Twenty-one patients were operated on by the trainee following the proposed iRARC curriculum [(t)iRARC group] and were compared with 42 patients treated with the standard of care by the mentor [(m)iRARC group]. To evaluate curriculum safety, peri-operative outcomes, surgical margins and complications were assessed. Propensity-score matching (1:2) was used to identify comparable (t)iRARC and (m)iRARC cases. Matched variables included age, body mass index, neoadjuvant therapy, American Society of Anesthesiologists score and cT stage. Mann-Whitney and chi-squared tests were used to compare peri- and postoperative outcomes between the two cohorts. To evaluate curriculum efficacy, steps attempted and completed by the trainee were assessed and studied as a function of growing surgical experience of the trainee. RESULTS: The trainee progressed in proficiency-based training through steps of increasing difficulty. No differences in estimated blood loss, positive soft tissue margins, number of resected lymph nodes, overall and high-grade complications, or 90-day readmissions between the (t)iRARC and (m)iRARC groups were observed (all P > 0.05). However, operating time was significantly longer in the (t)iRARC group (P = 0.01). Of the 209 available steps, the trainee attempted 168 (80%) and successfully performed 125 (60%). Increasing experience was associated with more steps being successfully performed (P < 0.001). CONCLUSIONS: The proposed ERUS curriculum assists naïve surgeons during the learning curve for iRARC and should be encouraged in order to guarantee optimal outcomes during the learning phase of this procedure.

OBJECTIVES: To evaluate the oncological and perioperative outcomes from a large, single-centre, robot-assisted radical cystectomy (RARC) cohort performed with intracorporeal urinary diversion (ICUD). PATIENTS AND METHODS: Patients who underwent RARC because of bladder cancer or recurrent carcinoma in situ from June 2009 until August 2020 at Herlev and Gentofte Hospital were prospectively and consecutively included. Kaplan-Meier survival analysis was used to estimate recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS). A Cox proportional hazards model was used to identify individual predictors of outcomes. Multiple logistic regression analysis was used to identify predictors of high-grade complications (Clavien-Dindo Grade ≥III). RESULTS: A total of 542 patients were included. The median (interquartile range) follow-up was 5.3 (2.73-8.06) years. In all, 78 patients (14%) were converted to open surgery; 15 (3%) during cystectomy and 63 patients (12%) were converted from ICUD to extracorporeal urinary diversion. The 5-year RFS, CSS and OS rates were 63% (95% confidence interval [CI] 59%-68%), 75% (95% CI 72%-80%) and 67% (95% CI 63%-72%), respectively. Pathological non-organ-confined disease (tumour stage >T2 or positive lymph nodes) predicted poorer RFS, CSS and OS. Reconstruction with a neobladder (20% of cases) compared to an ileal conduit was the only predictor of high-grade complications (odds ratio 2.54, 95% CI 1.46-4.43; P < 0.001). CONCLUSION: A RARC with ICUD is feasible as a standard surgical procedure for bladder cancer with only a few patients converted to open surgery. In our hands reconstruction with a neobladder was a strong predictor for high-grade complications.

PURPOSE: To report long-term oncologic and functional outcomes of a large consecutive single center series of Robot-assisted radical cystectomy (RARC)- intracorporeal (IC) Urinary Diversion (UD), identifying their predicting factors. METHODS: A single center Bladder cancer (BC) database was queried for "RARC" and "ICUD", including patients treated between January 2012 and September 2020. Kaplan-Meier curves were assessed disease-free (DFS), cancer-specific (CSS) and overall survival (OS) probability. Univariable (UV) and multivariable (MV) analysis were adopted to identify predictors of DFS, CSS and OS. Kaplan-Meier method evaluated day- and night-time continence recovery probabilities; UV and MV analysis were adopted to identify predictors of Day-time continence. RESULTS: Overall, 251 patients were included. Among them, 192 patients underwent intracorporeal ileal orthotopic neobladder (ION) (76.5%). Five-year DFS, CSS and OS rates were 66.5%, 65.4% and 61.5%; pT stage ≥ 3 and pathologic nodal involvement were identified as negative independent predictors of DFS (HR 2.39, p = 0.001, HR 4.64, p ≤ 0.001), CSS (HR 2.20, p = 0.01, HR 3.97, p < 0.001) and OS (HR 2.25, p = 0.005, HR 3.95, p < 0.001). In RARC-ION patients, Trifecta rate was 64.1%. One-year day- and night-time continence rates were 78.6% and 48.3%. Age (HR 0.98, p = 0.03), female gender (HR 0.57, p = 0.008) and complications Clavien grade ≥ 3 (HR 0.55, p = 0.03) were identified as independent predictors of day-time incontinence. CONCLUSIONS: Long-term oncologic outcomes and their predicting factors seem aligned to the largest historical open series and multi-institutional robotic series data. According to the identified predicting factors undermining a proper achievement of day-time continence, this represents an objective support, in order to properly advice specific sub-group of patients.

BACKGROUND: There is a potential benefit on long-term outcomes following complete mesocolic excision (CME) for right-sided colon cancer when compared to conventional colectomy. This study aims to analyze the learning curve and short-term outcomes of laparoscopic CME with intracorporeal anastomosis (ICA) for right-sided colon cancer in the hands of experienced colorectal surgeons. METHODS: A two-center cohort study of consecutive patients undergoing right-sided colectomy from September 2021 to May 2022 at two tertiary colorectal centers in Denmark. Learning curves of surgical time were estimated using a cumulative sum analysis (CUSUM). RESULTS: A total of 61 patients were included. According to the CUSUM analysis, 32 cases were needed to obtain a peak in operative time, resulting in a decrease in time consumption (group 1/learning phase: 217.2 min [SD 53.6] and group 2/plateau phase 191.6 min [SD 45.1], p = 0.05). There was a nonsignificant reduction in the rates of severe surgical complications (Clavien-Dindo > 3) (13% vs. 7%, p = 0.67) between the two groups, while the length of hospital stay remained constant (median 3.0 days, interquartile range, IQR [2.0; 4.0]). CONCLUSION: The learning curve of laparoscopic CME with ICA for right-sided colon cancer demonstrated that 32 cases were needed to obtain a plateau phase expressed by operative time.

BACKGROUND: Minimally invasive right hemicolectomy has been increasingly used for the treatment of right hemicolectomy disease, and both intracorporeal anastomosis (ICA) and extracorporeal anastomosis (ECA) are available to restore intestinal continuity. However, the advantages and disadvantages of these two anastomoses are highly controversial. The present meta-analysis evaluated the effectiveness of ICA versus ECA in minimally invasive right colectomy to improve the grade of evidence. METHODS: We searched the PubMed, Embase, Cochrane Library, and Web of Science databases for randomized controlled trials (RCTs) comparing intracorporeal versus extracorporeal anastomosis in laparoscopic or robotic right hemicolectomy published from database inception to February 2023. Two researchers performed the literature review, data extraction, bias assessment, and meta-analysis of the data using Review Manager 5.4 software. RESULTS: Seven RCTs with a total of 750 patients were included in the meta-analysis. The results showed a lower incidence of postoperative paralytic ileus (RR 0.62, 95% CI 0.39 ~ 0.99, p = 0.04) and shorter incision length (MD - 1.38; 95% CI: - 1.98 ~ - 0.78, p < 0.00001), but longer operative time (MD 10.69; 95% CI: 2.76 ~ 18.63, p = 0.008). The remaining events including bleeding (RR 0.49, 95% CI: 0.12 ~ 2.04, p = 0.33), anastomotic leak (RR 0.62, 95% CI: 0.39 ~ 0.99, p = 0.85), surgical site infection (RR 0.15, 95% CI: 0.22 ~ 1.25, p = 0.15), overall perioperative morbidity (RR 0.86, 95% CI: 0.58 ~ 1.26, p = 0.44), number of harvested lymph nodes (MD 0.75; 95% CI: - 0.15 ~ 1.65, p = 0.10), and length of hospital stay (MD - 0.27; 95% CI: - 0.91 ~ 0.38, p = 0.42) were not statistically significant. CONCLUSIONS: Compared to ECA, ICA in minimally invasive right hemicolectomy reduced the risk of postoperative paralytic ileus and shortened the length of the incision but prolonged the operative time.

AIM: During surgery for mid-transverse colon cancer (MTC), surgeons often face the dilemma of whether to mobilize the hepatic or splenic flexure. There is no established optimal minimally invasive surgical procedure for MTC. METHODS: We present our novel minimally invasive surgical technique, called the 'moving the left colon' technique for MTC, along with a video demonstration. The procedure involves four main steps: (i) mobilization of the splenic flexure using a medial-to-lateral approach, (ii) dissection of lymph nodes around the middle colic artery from the left side of the superior mesenteric artery approach, (iii) separation of the pancreas and transverse mesocolon and (iv) 'moving the left colon' and performing an intracorporeal anastomosis. By mobilizing the splenic flexure, anatomical landmarks are revealed, which enables safer dissection. Combining this technique with intracorporeal anastomosis allows for a safe and easy anastomosis. RESULTS: Between April 2021 and January 2023, a single-skilled colorectal surgeon performed laparoscopic transverse colectomies using our new approach on three consecutive patients with MTC. The patients had a median age of 75 years (range 46-89 years). The median operative time was 194 min (range 193-228 min) and blood loss was 8 mL (range 0-20 mL). None of the patients experienced any perioperative complications and the median postoperative hospital stay was 6 days. CONCLUSION: We introduced a novel approach for laparoscopic surgery for MTC. This technique can be performed safely and may help standardize minimally invasive surgery for MTC.
