RESUMO
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.

Introduction: There is a controversy in minimally invasive colorectal procedures regarding choosing optimal technique between intra-corporeal (ICA) and extra-corporeal anastomosis (ECA). Previous studies recognize the short-term benefits in right hemicolectomy with intra-corporeal approach; however, ICA can result in increased operative difficulty. The aim of this study is to understand attitudes towards teaching ICA in colorectal procedures and how this varies between subspeciality training. Methods: Active members of General Surgeons Australia were contacted through email to participate in a voluntary, unincentivized survey. Demographic details were collected and participants were asked to rate agreement for simulation-based training for increasing adoption of ICA through a Likert scale and when preferences for teaching ICA. Descriptive statistics were completed to describe frequencies and ordinal regression was completed to determine factors for Likert scale question. Results: There were 43 respondents and most participants recognized that ECA was easier to teach trainees and should be taught first. 53.5% of respondents recognized that simulation-based training would assist the adoption of ICA. Surgeons who routinely close bowel or enteric defects intra-corporeally are 354% more likely to show an interest in simulation-based training for adopting ICA, however, surgeons who are not involved in teaching trainees did not show an interest in simulation-based training. Conclusion: There is significant agreement that ECA forms the basis to learn ICA and simulation-based training would assist with the uptake of ICA. However, a multimodal approach, including expanding training avenues and providing financial incentives, would be necessary to enhance the adoption of ICA in colorectal surgery.

We recently read the study by Kayano et al on intracorporeal anastomosis (IA) for colon cancer, which assessed bacterial contamination and medium-term oncological outcomes and affirmed that IA is analogous to extracorporeal anastomosis in reducing intraperitoneal bacterial risk and achieving similar oncological results. Our commentary addresses gaps, particularly concerning bowel preparation and surgical site infections (SSIs), and highlights the need for comprehensive details on the bowel preparation methods that are currently employed, including mechanical bowel preparation, oral antibiotics (OA), their combination, and specific OA types. We emphasize the necessity for further analyses that investigate these methods and their correlation with SSI rates, to enhance clinical protocol guidance and optimize surgical outcomes. Such meticulous analyses are essential for refining strategies to effectively mitigate SSI risk in colorectal surgeries.
RESUMO
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.

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.

PURPOSE: We studied the effect of a platelet-rich fibrin matrix (PRFM) combined with prostaglandin E-1 (PGE-1) injection on erectile function in patients refractory to response for phosphodiesterase type 5 inhibitors (PDE5-Is). METHODS: This randomized, double-blind, placebo-controlled study included 80 patients. The patients were randomly assigned to four groups and blinded together with the administrating physicians to the nature of the intracorporeal injection (ICI) therapies. Group (1) received saline, group (2) received platelet-rich fibrin matrix (PRFM), group (3) received prostaglandin E-1 (PGE-1), and group (4) received a combination of PRFM + PGE-1. The patients received ICI therapy weekly for 8 consecutive weeks. Clinical information and follow-up data were obtained at 1, 2, 3, and 6 months. RESULTS: A significant increase occurred in the validated Arabic version of the International Index of Erectile Function (ArIIEF-5) score in group (4) compared to the other three groups (p value = 0.037). There was a significant difference in erection hardness scale (EHS) scores among all groups after receiving the different treatments (p = 0.004). A significant increase was seen in the ArIIEF-5 score in groups 4 and 3 compared to that in groups 1 and 2 (p < 0.001). There was also a significant increase in the arterial dilatation % in groups 4 and 3 compared to that in groups 1 and 2 (p = 0.019). CONCLUSION: The combination of PRFM plus PGE-1 had shown significant improvement in the ArIIEF-5 score, yet the patients still had mild to moderate ED.
RESUMO
INTRODUCTION: The benefits of intracorporeal anastomosis in laparoscopic colorectal cancer surgery remain unclear. Therefore, we aimed to investigate the short-term postoperative outcomes of intracorporeal anastomosis. METHODS: We retrospectively analyzed 87 patients who underwent laparoscopic surgery for right-sided colon tumors using a colon database. RESULTS: Of the 87 patients, 23 underwent intracorporeal anastomosis and 64 underwent extracorporeal anastomosis. Intraoperative bleeding, wound length, exhaust gas, preoperative white blood cell count, and C-reactive protein (postoperative day 1) were higher in the extracorporeal anastomosis group than in the intracorporeal anastomosis group. The incidence of wound infection was higher in the intracorporeal anastomosis group than in the extracorporeal anastomosis group. In the irrigation water bacterial culture collected after anastomosis, the positive group had a higher white blood cell count on postoperative day 1 and higher C-reactive protein levels on postoperative day 3 than did the negative group. Patients who underwent chemical preparation had lower C-reactive protein levels on postoperative day 1 than did the group who did not undergo chemical preparation. CONCLUSION: Despite the advantages of intracorporeal anastomosis in terms of wound length and intraoperative bleeding, the risk of infection may increase during the introduction phase. Fever and inflammatory responses are significantly elevated in culture-positive cases.

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.

The primary objective of this study was to compare short-term outcomes between Intracorporeal ileocolic anastomosis (IIA) and extracorporeal ileocolic anastomosis (EIA) after laparoscopic right hemicolectomy in patients with visceral obesity. The secondary objective was to identify risk factors associated with prolonged postoperative ileus (PPOI) after laparoscopic right hemicolectomy. This single-center retrospective study analyzed visceral obesity patients who underwent laparoscopic right hemicolectomy for primary bowel cancer between January 2020 and June 2023. Patients were categorized into IIA and EIA groups based on the type of anastomosis, and a 1:1 propensity score-matched analysis was performed. A total of 129 patients were initially included in this study, with 45 patients in each group following propensity score matching. The IIA group had significantly longer anastomosis times (p < 0.001), shorter incision length (p < 0.001), and shorter length of stay (p = 0.003) than the EIA group. Meanwhile, the IIA group showed a shorter time to first flatus (p = 0.044) and quicker tolerance of a solid diet (p = 0.030). On multivariate analysis, postoperative use of opioid analgesics is an independent risk factor for PPOI (OR: 3.590 95% CI 1.033-12.477, p = 0.044), while IIA is an independent protective factor (OR: 0.195 95% CI 0.045-0.843, p = 0.029). IIA remains a safe and feasible option for visceral obesity patients. It is also associated with a quicker recovery of bowel function and shorter length of stay when compared to EIA. Additionally, IIA is an independent protective factor for PPOI.

Background Anastomosis formed in minimally invasive laparoscopic right hemicolectomy (LRH) may be achieved intra-corporeally (ICA) or extra-corporeally (ECA). This study compared the return of bowel function and other associated early patient outcomes and morbidity rates after an ICA or ECA in LRH. Methodology The study conducted a single-center retrospective cohort study of elective LRH from January 2021 to September 2023. Patient demographics, surgical techniques, and outcomes were analyzed using IBM SPSS Statistics for Windows, Version 29.0 (IBM Corp., Armonk, NY). Results Ninety participants underwent LRH, and the anastomotic type was evenly distributed - with male patients comprising 53 (58.9%) of the total. The mean age was 64 (standard deviation [SD] ±16.8) years, and the median body mass index (BMI) was 27.0 (interquartile range [IQR] = 7.8). The mean follow-up period was 5.1 (SD ± 6.0) months. Univariate analysis showed that ICA had a shorter time for return of bowel function (P < 0.01). Additionally, ICA was associated with lower pain scores (P < 0.01), low morbidity (P = 0.02), and shorter hospital stays (P = 0.01). When comparing ICA to ECA, no significant difference was observed for procedure duration (P = 0.13), anastomotic leak (AL, P = 1.00), surgical-site infections (P = 0.36), lymph node yield (P = 0.26), and any-cause mortality. Multivariate logistic regression, controlling for statistically insignificant confounding factors, revealed that ECA was significantly and independently associated with increased time to first flatus (odds ratio [OR] 2.3, P = 0.01) and higher average postoperative pain (OR 1.5, P = 0.02) compared to ICA. Conclusions This single-center experience showed that ICA is associated with a quicker return to normal bowel function and low morbidity outcomes. ICA participants were positively associated with clinically relevant and health economics outcomes of shorter hospital stays without significantly adding to the procedure's duration times or compromising principles of oncological resection yield.
RESUMO
To compare the short-term outcomes and explore the potential economic benefits of laparoscopic-assisted colectomy with extracorporeal anastomosis (LAC/EA) vs. laparoscopic complete colectomy with intracorporeal anastomosis (LCC/IA) for patients with non-metastatic resectable colon cancer. Data of patients who underwent laparoscopic hemicolectomy from January 2017 to March 2023 were collected and analyzed. Propensity score matching (PSM) analyses was carried out to minimize the selection bias. Before PSM, a total of 113 patients met the inclusion criteria (39 in the LCC/IA vs. 74 in the LAC/EA). Clinicopathologic characteristics were comparable except for the median number of removed lymph nodes (P = 0.023). LCC/IA was associated with longer operative time, less intraoperative blood loss, and shorter incision length. The rate of 30-day postoperative complications was similar, but the time to first flatus and soft diet was shorter in the LCC/IA. No deaths were reported in either group within 30 days after surgery. Costs of surgical instruments (25,945.8 ± 1,918.0 vs. 23,551.9 ± 2,665.5 RMB; P < 0.01) were higher for the LCC/IA but overall costs were similar (LCC/IA, 43,220.0 ± 4,954.0 vs. LAC/EA, 41,269.2 ± 6,685.9 RMB; P = 0.112). After PSM, 38 patients in the LCC/IA and 63 patients in the LAC/EA were compared. LCC/IA was superior in terms of intraoperative blood loss, incision length, and postoperative functional recovery. There was an extra charge of 2385.0 RMB regarding surgical instruments in the LCC/IA but the overall cost did not reach statistical significance. LCC/IA is a feasible, safe, and cost-effective surgical treatment for patients with non-metastatic resectable colon cancer.
RESUMO
Objective: Closure of the appendix stump after appendectomy is considered one of the most important parts of laparoscopic appendectomy. Various techniques are used during this surgery, commonly including endoclips and ligatures. Therefore, this study was conducted to compare endoclips with intra-corporeal ligatures in closing the appendix stump during laparoscopic appendectomy. Methods: This retrospective study was conducted using data from 50 patients with acute appendicitis who underwent uncomplicated laparoscopic appendectomy. The data from patients whose stumps were closed using endoclips in 25 patients (Group I) and with intra-corporeal ligatures in 25 patients (Group II) were extracted and compared regarding the occurrence of intraoperative and postoperative complications. Results: There were no differences between the two methods in terms of intraoperative and postoperative complications. The duration of surgery in the ligature group was significantly longer than in the clip group (p = 0.044). The hospital stay duration was clinically longer in the ligature group, but this difference was not statistically significant (p > 0.05). Conclusion: Endoclips for closing the appendix stump are safer with a shorter operating time and also a simpler method. Therefore, they could be a reliable alternative to the method of closing the appendix stump with ligatures.
RESUMO
INTRODUCTION: Benefits and harms of avoid the sent placement during IntraCorporeal Neobladder configuration are still debated. Our objective was to describe the step-by-step technique of Florence intracorporeal neobladder (FloRIN) configuration performed with stentless procedure focusing on perioperative and mid-term functional outcomes. MATERIALS AND METHODS: In this single institution prospective randomized 1:1 series all consecutive patients underwent Robot-Assisted Radical Cystectomy (RARC) and FloRIN reconfiguration from January 2021 to March 2021 were enrolled. Functional perioperative and mid-term outcomes were gathered. Postoperative complications were graded according to Clavien-Dindo classification and divided in early (<30 days from discharge) and delayed (>30 days). RESULTS: Overall, 10 patients were included in the analysis. Of these, the 50.0% was treated with Stentless FloRIN. In terms of baseline features, no differences were recorded between the two groups. Median age was 65 and 66 years while median BMI was 27 and 25 in the stentless and in the stent group, respectively. Concerning intraoperative variables, no intraoperative complications as well as open conversion occurred among both groups. As regard introperative features, a shorter console time was associated with stentless procedure (331 min vs 365 min). In terms of perioperative outcomes, canalization and time to drainage removal didn't differ between groups while length of hospital stay was significantly lower in stentless group 10 days versus 14 days. Early and delayed postoperative complication rate was not influenced by the ureteral management at a preliminary assessment with comparable rates of Clavien Dindo ⩾ 3a between the two groups. Mid-term functional outcomes did not differ between groups in terms of kidney function loss. CONCLUSIONS: FloRIN with Stentless technique showed functional and perioperative preliminary outcomes comparable with the standard ureteral management strategy. Further series with longer functional follow-up assessment will be needed to confirm our preliminary results.

INTRODUCTION: This study was performed to evaluate the differences in the perioperative results, renal function, and incidence of hydronephrosis over time between the use of Bricker anastomosis and Wallace anastomosis for robot-assisted intracorporeal ileal conduit urinary diversion (RICIC). METHODS: Fifty-five patients who underwent RICIC at two institutions were evaluated (Bricker, n = 23; Wallace, n = 32). We investigated changes in estimated glomerular filtration rate and hydronephrosis before surgery and at 3, 6, and 12 months after surgery. RESULTS: The patients in the Bricker group were significantly older than those in the Wallace group. The urinary diversion time was significantly longer in the Bricker group. No significant difference in postoperative renal function was observed. Additionally, no significant difference was observed in the incidence of postoperative hydronephrosis. However, the incidence of right hydronephrosis tended to be high overall, especially in the Wallace group. No patients in either group required repair surgery or ureteral stent placement. CONCLUSIONS: In patients undergoing RICIC, there was no difference in postoperative renal function or the incidence of hydronephrosis between Wallace and Bricker anastomosis. Symptomatic hydronephrosis was not observed in either group. The present study showed that each method was equally effective and safe.

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.

BACKGROUND: Although intracorporeal anastomosis (IA) for colon cancer requires longer operative time than extracorporeal anastomosis (EA), its short-term postoperative results, such as early recovery of bowel movement, have been reported to be equal or better. As IA requires opening the intestinal tract in the abdominal cavity under pneumoperitoneum, there are concerns about intraperitoneal bacterial infection and recurrence of peritoneal dissemination due to the spread of bacteria and tumor cells. However, intraperitoneal bacterial contamination and medium-term oncological outcomes have not been clarified. AIM: To clarify the effects of bacterial and tumor cell contamination of the intra-abdominal cavity in IA. METHODS: Of 127 patients who underwent laparoscopic colon resection for colon cancer from April 2015 to December 2020, 75 underwent EA (EA group), and 52 underwent IA (IA group). After propensity score matching, the primary endpoint was 3-year disease-free survival rates, and secondary endpoints were 3-year overall survival rates, type of recurrence, surgical site infection (SSI) incidence, number of days on antibiotics, and postoperative biological responses. RESULTS: Three-year disease-free survival rates did not significantly differ between the IA and EA groups (87.2% and 82.7%, respectively, P = 0.4473). The 3-year overall survival rates also did not significantly differ between the IA and EA groups (94.7% and 94.7%, respectively; P = 0.9891). There was no difference in the type of recurrence between the two groups. In addition, there were no significant differences in SSI incidence or the number of days on antibiotics; however, postoperative biological responses, such as the white blood cell count (10200 vs 8650/mm3, P = 0.0068), C-reactive protein (6.8 vs 4.5 mg/dL, P = 0.0011), and body temperature (37.7 vs 37.5 °C, P = 0.0079), were significantly higher in the IA group. CONCLUSION: IA is an anastomotic technique that should be widely performed because its risk of intraperitoneal bacterial contamination and medium-term oncological outcomes are comparable to those of EA.
RESUMO
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.

OBJECTIVE: To assess the short-term functional outcomes and morbidity of robotic-assisted cystectomy (RAC) and intracorporeal urinary diversion (ICUD) in patients with lower urinary tract dysfunction (LUTD). METHODS: All consecutive patients who underwent RAC+ICUD for LUTD in a tertiary hospital center, between July 2018 and May 2021 were retrospectively included. Medical records were systematically reviewed and patient, perioperative and postoperative data were collected. A good short-term functional outcome was defined by the combination of a satisfying urostomy equipment (absence of urine leakage and easy appliance of the urostomy bag), the absence of pelvicaliceal system dilatation on sonography, and the absence of renal function decrease at the 2months post-operative consultation. Intraoperative parameters and post-operative complications were collected to assess morbidity. RESULTS: Thirty-five patients were included. Eight (22.8%) patients needed intraoperative conversion to laparotomy. Twenty-five patients (92,5%) met criteria for a good functional outcome 2months post-operatively. The median operative time was 346min (86.5-407.5). The median blood loss was 100mL (100-290) and 5 patients (18.5%) required blood transfusion. The median times to return of bowel function was 3 days (2-4) and the median length of hospital stay was 10 days (10-18). Peri-operative complications were reported in 16 patients (59.2%): 6 (22.2%) minor complications Clavien ≤ II and 10 (37%) major complications Clavien ≥ III. There was no significative decrease of the renal function (mean preoperative creatininemia of 61.2µmol/L (50.5-74.5) vs 64.5µmol/L (47-85.25) postoperatively) CONCLUSION: RAC+ICUD in LUTD can provide good short-term functional outcomes while limiting blood transfusion, time to return of bowel function and the length of hospital stay. These results should be confirmed by larger prospective study.

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.
