Abstract
OBJECTIVE To analyze postoperative ileus rates and postoperative complications between the different pneumoperitoneum settings. The secondary objective was to evaluate narcotic use and intraoperative blood loss between the different pneumoperitoneum settings. METHODS A prospective, randomized, double blinded study was conducted at pneumoperitoneum pressures of either 12 mmHg or 15 mmHg for patients undergoing robotic assisted radical prostatectomy with bilateral pelvic lymph node dissection by a single high volume surgeon. RESULTS The risk of ileus in the 12 mmHg group was 1.9% (2/105) compared to 3.2% (3/93) in the 15 mmHg group (OR 0.58, 95%CI 0.1-3.6). There was no difference in the risk of any complication with a complication rate of 4.8% (5/105) in the 12 mmHg arm compared to 4.3% (4/93) in the 15 mmHg arm (OR 1.1, 95% CI 0.3 - 4.3). CONCLUSION Pneumoperitoneum pressure setting of 12 mmHg has no significant difference to 15 mmHg in the rate of postoperative complications, narcotic use, and intraoperative bleeding. Additional research is warranted to understand the optimal.

Int J Surg 2024; 110:1744-1754. [PMID: 38085848 PMCID: PMC10942148 DOI: 10.1097/js9.0000000000000988] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Accepted: 11/27/2023] [Indexed: 03/16/2024]
Abstract
BACKGROUND Postoperative ileus (POI) is a complication that may occur after abdominal or nonabdominal surgery. Intravenous dexmedetomidine (Dex) has been reported to accelerate postoperative gastrointestinal function recovery; however, updated evidence is required to confirm its robustness. METHODS To identify randomized controlled trials examining the effects of perioperative intravenous Dex on gastrointestinal function recovery in patients undergoing noncardiac surgery, databases including MEDLINE, EMBASE, Google Scholar, and Cochrane Library were searched on August 2023. The primary outcome was time to first flatus. Secondary outcomes included time to oral intake and defecation as well as postoperative pain scores, postoperative nausea/vomiting (PONV), risk of hemodynamic instability, and length of hospital stay (LOS). To confirm its robustness, subgroup analyses and trial sequential analysis were performed. RESULTS The meta-analysis of 22 randomized controlled trials with 2566 patients showed that Dex significantly reduced the time to flatus [mean difference (MD):-7.19 h, P <0.00001), time to oral intake (MD: -6.44 h, P =0.001), time to defecation (MD:-13.84 h, P =0.008), LOS (MD:-1.08 days, P <0.0001), and PONV risk (risk ratio: 0.61, P <0.00001) without differences in hemodynamic stability and pain severity compared with the control group. Trial sequential analysis supported sufficient evidence favoring Dex for accelerating bowel function. Subgroup analyses confirmed the positive impact of Dex on the time to flatus across different surgical categories and sexes. However, this benefit has not been observed in studies conducted in regions outside China. CONCLUSIONS Perioperative intravenous Dex may enhance postoperative gastrointestinal function recovery and reduce LOS, thereby validating its use in patients for whom postoperative ileus is a significant concern.

[PMID: 37892902 PMCID: PMC10604161 DOI: 10.3390/bioengineering10101172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 09/25/2023] [Accepted: 09/26/2023] [Indexed: 10/29/2023] Open
Abstract
Individualized positive end-expiratory pressure (PEEP) combined with recruitment maneuvers improves intraoperative oxygenation in individuals undergoing robot-assisted prostatectomy. However, whether electrical impedance tomography (EIT)-guided individualized PEEP without recruitment maneuvers can also improve intraoperative oxygenation is unknown. To test this, fifty-six male patients undergoing elective robot-assisted laparoscopic prostatectomy were randomly assigned to either individualized PEEP (Group PEEPIND, n = 28) or a control with a fixed PEEP of 5 cm H2O (Group PEEP5, n = 28). Individualized PEEP was guided by EIT after placing the patients in the Trendelenburg position and performing intraperitoneal insufflation. Patients in Group PEEPIND maintained individualized PEEP without intermittent recruitment maneuvers, and those in Group PEEP5 maintained a PEEP of 5 cm H2O intraoperatively. Both groups were extubated in a semi-sitting position once the extubation criteria were met. The primary outcome was arterial oxygen partial pressure (PaO2)/inspiratory oxygen fraction (FiO2) prior to extubation. Other outcomes included intraoperative driving pressure, plateau pressure and dynamic, respiratory system compliance, and the incidence of postoperative hypoxemia in the post-operative care unit (PACU). Our results showed that the intraoperative median for PEEPIND was 16 cm H2O (ranging from 12 to 18 cm H2O). EIT-guided PEEPIND was associated with higher PaO2/FiO2 before extubation compared to PEEP5 (71.6 ± 10.7 vs. 56.8 ± 14.1 kPa, p = 0.003). Improved oxygenation extended into the PACU with a lower incidence of postoperative hypoxemia (3.8% vs. 26.9%, p = 0.021). Additionally, PEEPIND was associated with lower driving pressures (12.0 ± 3.0 vs. 15.0 ± 4.4 cm H2O, p = 0.044) and better compliance (44.5 ± 12.8 vs. 33.6 ± 9.1 mL/cm H2O, p = 0.017). Our data indicated that individualized PEEP guided by EIT without intraoperative recruitment maneuvers also improved perioperative oxygenation in patients undergoing robot-assisted laparoscopic radical prostatectomy, which could benefit patients with the risk of intraoperative hemodynamic instability caused by recruitment maneuvers. Trial registration: China Clinical Trial Registration Center Identifier: ChiCTR2100053839. This study was registered on 1 December 2021. The first patient was recruited on 15 December 2021.

Comparing different pneumoperitoneum (12 vs. 15 mmHg) pressures with cytokine analysis to evaluate clinical outcomes in patients undergoing robotic-assisted laparoscopic radical cystectomy and intracorporeal robotic urinary diversion. BJUI COMPASS 2023; 4:575-583. [PMID: 37636200 PMCID: PMC10447212 DOI: 10.1002/bco2.240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 03/05/2023] [Accepted: 03/17/2023] [Indexed: 08/29/2023] Open
Abstract
Background Robotic cystectomy is the mainstay surgical intervention for treatment-refractory nonmuscle-invasive and muscle-invasive bladder cancer. However, paralytic ileus may complicate the postoperative recovery and may be a consequence of an inflammatory response associated with transient gut ischaemia. We have therefore investigated clinical, operative and inflammatory biomarker associations between paralytic ileus in the context of robotic cystectomy and intracorporeal ileal conduit urinary diversion. Methods Prospective consective patients referred for robotic cystectomy were consented and included in the study, while patients >75 years old and converted to open procedure were excluded. The pneumoperitoneum pressure (PP) for carbon dioxide insufflation required to perform the procedure efficiently and safely was recorded (12 or 15 mmHg). We also recorded the postoperative days patients passed flatus and stools, whether they developed ileus, as well as other standard clinical and demographic data. The expression of select proinflammatory and anti-inflammatory cytokines was determined by multiplex analysis using a cytometric bead array with changes in profiles correlated with the pressures applied and with the existence of an ileus. Results Twenty-seven patients were recruited, but only 20 were used in the study with 10 patients in each PP group. Seven patients were excluded all of whom had an extracorporeal ileal conduit formation. There were differences in the 40-min shorter operative time and 1 day shorter length of stay, as well as passing flatus 1 day and stools 1.5 days earlier in the 12 mmHg compared with the 15 mmHg group. More patients had ileus in the 15 mmHg group vs 12 mmHg group (30% vs. 10.0%). These were not statistically significant. Similarly, there were no statistical differences in the expression of proinflammatory cytokines at the two different pressures or between patient groups, but there were outliers, with the median indicating nonsymmetrical distribution. By comparison, anti-inflammatory cytokines showed some significant differences between groups, with IL-6 and IL-10 showing elevated levels postsurgery. No statistical difference was observed between pressures or the existence of an ileus, but the maximum levels of IL-6 and IL-10 detected in some patients reflect a pressure difference. Conclusions The initial findings of this novel scientific study indicated a higher risk of paralytic ileus postrobotic cystectomy and robotic intracorporeal urinary diversion when a higher pressure of 15 mmHg is used compared with 12 mmHg. Although further studies are required to establish the linkage between cytokine profile expression, pressure and ileus, our initial data reinforces the advantages of lower pressure robotic cystectomy and intracorporeal urinary diversion in patient outcomes.

Abstract
Objective To determine the preventive effect of melatonin on delirium in the intensive care units. Methods We conducted a systematic search of the PubMed, Cochrane Library, Science, Embase, and CNKI databases, with retrieval dates ranging from the databases' inception to September 2022. Controlled trials on melatonin and placebo for preventing delirium in the intensive care units were included. The meta-analysis was performed using Review Manager software (version 5.3) and Stata software (version 14.0). Results Six studies involving 2374 patients were included in the meta-analysis. The results of the meta-analysis showed that melatonin did not reduce the incidence of delirium in ICU patients (odds ratio [OR]: 0.71; 95% confidence interval [CI]: 0.46 to 1.12; p = 0.14). There was a strong hetero-geneity between the selected studies (I2 = 74%). Subgroup analysis results showed that melatonin reduced the incidence of delirium in cardiovascular care unit (CCU) patients (OR: 0.52; 95% CI: 0.37 to 0.73; p=0.0001), but did not in general intensive care unit (GICU) patients (OR: 1.14; 95% CI: 0.86 to 1.50; p=0.35). In terms of the secondary outcomes, there were no significant differences in all-cause mortality (OR: 0.85; 95% CI: 0.66 to 1.09; p=0.20), length of ICU stay (mean difference [MD]: 0.33; 95% CI: -0.53 to 1.18; p=0.45), or length of hospital stay (MD: 0.51; 95% CI: -1.17 to 2.19; p=0.55). Conclusion Melatonin reduced the incidence of delirium in CCU patients, but did not significantly reduce the incidence of delirium in GICU patients.

The Impact of intra-abdominal Pressure on Perioperative Outcomes in Robotic-Assisted Radical Prostatectomy: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials. JOURNAL OF ONCOLOGY 2022; 2022:4974027. [DOI: 10.1155/2022/4974027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 10/23/2022] [Accepted: 10/31/2022] [Indexed: 11/16/2022]
Abstract
Objective. The aim of the study is to analyze the impact of intra-abdominal pressure (IAP) on perioperative outcomes in robotic-assisted radical prostatectomy (RARP). Methods. We searched the PubMed, Cochrane Library, Science, Embase, and CNKI databases systematically, and the retrieval date was from the inception of the databases to April 2022. Randomized controlled trials on high intraabdominal pressure (HIAP) and low intraabdominal pressure (LIAP) in RARP were included. The meta-analysis was performed using Review Manager software (version 5.3). Results. Six studies involving 2,271 patients were included in the meta-analysis. Compared with patients who experienced HIAP, those who experienced LIAP had a lower incidence of postoperative ileus (POI) (risk ratio (RR): 0.42; 95% confidence interval (CI): 0.24 to 0.72;
). However, there were no significant differences in hematoma (RR 2.22; 95% CI, 0.61 to 8.15;
), positive margin rate (RR, 1.06; 95% CI, 0.84 to 1.32;
), urinary retention (RR, 0.99; 95% CI, 0.51 to 1.94;
), operative time (mean difference (MD), −0.36; 95% CI, −12.24 to 6.12;
), or intraoperative blood loss (MD, −21.80; 95% CI, −55.28 to 11.68;
) among patients undergoing LIAP and HIAP. Conclusion. Our study of published trials indicates that using LIAP during RARP may reduce the incidence of POI, and there were no differences in terms of hematoma, positive margin rate, urinary retention, operative time, or intraoperative blood loss.

Clinical outcomes of low-pressure pneumoperitoneum in minimally invasive urological surgery. J Robot Surg 2022; 16:1183-1192.

Abstract
The adoption of minimally invasive laparoscopic techniques has revolutionised urological practice. This necessitates a pneumoperitoneum (PNP) and the impact the PNP pressure has on post-operative outcomes is uncertain. During the current COVID-19 era guidance has suggested the utilisation of lower PNP pressures to mitigate the risk of intra-operative viral transmission. Review the current literature regarding the impact of pneumoperitoneum pressure, within the field of urology, on post-operative outcomes. A search of the PubMed, Medline and EMBASE databases was undertaken to identify studies that met the inclusion criteria. The Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines were adhered to. Ten studies, that included both randomised controlled trials and retrospective case series reviews, were identified that met the inclusion criteria. The effect of PNP pressure on outcomes following prostatectomy, live donor nephrectomy, partial nephrectomy and a variety of benign upper tract procedures were discussed. Low pressure PNP appears safe when compared to high pressure PNP, potentially reducing post-operative pain and rates of ileus. When compared to general surgery, there is a lack of quality evidence investigating the impact of PNP pressures on outcomes within urology. Low pressure PNP appears non-inferior to high pressure PNP. More research is required to validate this finding, particularly post-cystectomy and nephrectomy.

Lower vs standard pressure pneumoperitoneum in robotic-assisted radical prostatectomy: a systematic review and meta-analysis. J Robot Surg 2022; 17:303-312.

Abstract
Robotic-assisted laparoscopic radical prostatectomy (RARP) has been traditionally performed at a pneumoperitoneum insufflation pressure of 12-15 mmHg. This meta-analysis and systematic review aims to assess the current evidence comparing lower to standard pressure pneumoperitoneum in RARP. Systematic searches of MEDLINE, COCHRANE, SCOPUS and EMBASE were performed to identify articles published up until November 2021 comparing lower pressure with standard pressure pneumoperitoneum in RARP. Standard pressure was defined as > 12 mmHg and lower pressure ≤ 12 mmHg. Estimated blood loss, length of operation, length of hospital stay, post-operative ileus, 30-day readmissions, Clavien-Dindo complications and rate of positive surgical margins were extracted as endpoints of interest. Our searches identified 165 abstracts of which 4 articles with 1319 patients were eligible. Cumulative analysis demonstrated reduced length of stay when a lower pressure was used: WMD - 0.23 (- 0.45 to - 0.02) days (p = 0.03) as well as a reduced rate of post-operative ileus: OR 0.41 (0.22 to 0.77) (p = 0.006). There was no significant increase in length of operation WMD - 1.79 (- 15.96 to 12.38) (p = 0.8), estimated blood loss WMD - 2.89 (- 29.41 to 23.62) (p = 0.83), 30-day readmissions or positive surgical margins OR 1.04 (0.78 to 1.38) (p = 0.81) and RD - 0.01 (- 0.04 to 0.01) (p = 0.3) when using a lower pressure. We have demonstrated reduced length of stay and rates of post-operative ileus, when performing RARP at a lower pressure without a significant increase in length of operation, estimated blood loss, positive surgical margins or complications. The recommendation to use lower pressure pneumoperitoneum is moderate to weak and more randomised control trials are required to validate these results.

Abstract
This study was to show the impact of ‘prostate-muscle index (PMI)’, which we developed as a novel pelvic cavity measurement, in patients undergoing robot-assisted radical prostatectomy (RARP). We defined PMI as the ‘distance between the inner edge of the obturator internus muscle and the lateral edge of the prostate at the magnetic resonance imaging (MRI) slice showing the maximum width of the prostate’. Seven hundred sixty patients underwent RARP at the University of Tokyo Hospital from November 2011 to December 2018. MRI results were unavailable in 111 patients. In total, 649 patients were eligible for this study. Median values of blood loss and console time were 300 mL and 168 min. In multivariate analysis, body mass index (BMI), prostate volume-to-pelvic cavity index (PV-to-PCI), PMI, and surgical experience were significantly associated with blood loss > 300 mL (P = 0.0002, 0.002, < 0.0001, and 0.006 respectively). Additionally, BMI, PMI, and surgical experience were also significantly associated with console time > 160 min in multivariate analysis (P = 0.04, 0.004, and < 0.0001, respectively). In conclusion, PMI may provide useful information to surgeons and patients in preoperative decision-making.

Abaza R, Kogan P, Martinez O. Narcotic Avoidance After Robotic Radical Cystectomy Allows Routine of Only Two-Day Hospital Stay. Urology 2021; 161:65-70. [PMID: 34968571 DOI: 10.1016/j.urology.2021.10.049] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Revised: 10/22/2021] [Accepted: 10/31/2021] [Indexed: 11/17/2022]
Abstract
OBJECTIVE To evaluate the outcomes of a narcotic-sparing clinical pathway after robotic-assisted radical cystectomy (RARC) with ileal conduit targeting discharge on postoperative day #2 and report postoperative narcotic consumption, pain scores, and the resulting length of stay (LOS). METHODS We reviewed a single-surgeon series of consecutive RARCs between August 2015-September 2020. Acetaminophen and ketorolac were given with thorough patient education reserving oral narcotics for breakthrough pain. Intravenous narcotics were intentionally excluded from postoperative orders. Alvimopan was given once it became available. Subcutaneous ropivacaine pain pumps were removed before discharge. Discharge criteria included diet, oral analgesia, ambulation, and bowel function. Narcotic use and pain scores were evaluated to deternine the success of the applied narcotic-avoidance strategy. RESULTS None of the 54 patients required intravenous narcotics postoperatively, and 19 patients (35%) never required even oral narcotics. Mean pain scores were higher in patients who required oral narcotics (4.3/11 vs 3.0/11, p=0.001, respectively). Among 35 patients who received narcotics, mean tablets taken were 4.3/day (range, 1-13) with 68% using 8 or less tablets during their entire LOS. Mean LOS was 2.1d (range 1-4). Five patients (9%) were discharged on POD#1, 37/54 (68.5%) on POD #2, 10/54 (18.5%) on POD#3 and 2/54 (4%) on POD #4. Eight patients (15%) were readmitted within 90 days. CONCLUSION Minimizing narcotics after RARC with conduit allowed for a 2-day LOS in the majority of patients and the shortest ever reported mean LOS after cystectomy, essentially halving hospitalization time. Patient education is critical to minimizing narcotic usage.

Deep Neuromuscular Blockade Combined with Low Pneumoperitoneum Pressure for Nociceptive Recovery After Major Laparoscopic Gastrointestinal Surgery: Study Protocol for a Randomized Controlled Trial. J Pain Res 2021; 14:3573-3581. [PMID: 34815710 PMCID: PMC8605867 DOI: 10.2147/jpr.s336870] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Accepted: 11/09/2021] [Indexed: 11/23/2022] Open
Abstract
Purpose Patients undergoing major laparoscopic surgery often experience significant pain and postoperative nausea and vomiting (PONV). Deep neuromuscular block (NMB) improves surgical conditions and facilitates the application of low intra-abdominal pressure (IAP), which may be beneficial for these patients. This study is designed to determine the effects of deep NMB combined with low IAP, as compared to moderate NMB combined with standard IAP, on patients' nociceptive recovery after major laparoscopic gastrointestinal surgery. Study Design and Methods This single-center randomized controlled trial will include 220 patients scheduled for major laparoscopic gastrointestinal surgery (lasts for ≥ 90 minutes). Patients will be randomly assigned, with a 1:1 ratio, into a deep NMB + low IAP group (train of four = 0, post-tetanic count = 1-3, IAP = 8 mmHg) and a moderate NMB + standard IAP group (train of four = 1-3, IAP = 12 mmHg). If the surgical workspace is inadequate, the surgeons can request a step increase of 1 mmHg in IAP during 3-min intervals. The upper limit of IAP will be set at 15 mmHg. Postoperative recovery will be assessed using the postoperative quality recovery scale (PQRS). The primary outcome of this trial is the PQRS nociceptive recovery (including pain and PONV) at postoperative day (POD) 1. The secondary outcomes include recovery in other PQRS domains at POD 1, and recovery in all PQRS domains in a post-anesthesia care unit, at POD 3 in the surgical wards, at hospital discharge, and at postoperative 30 days. For the sample size estimation, 110 patients in each group (220 in total) would be needed to detect an absolute increase rate of 20% in the PQRS nociceptive domain in the deep NMB + low IAP group at POD 1. Discussion This study investigates the effects of deep NMB combined with low IAP on postoperative PQRS nociceptive recovery in patients undergoing major laparoscopic gastrointestinal surgery. We expect that this deep NMB + low IAP strategy would improve postoperative pain and PONV following major laparoscopic gastrointestinal surgery.

Impact of intravenous dexmedetomidine on postoperative bowel movement recovery after laparoscopic nephrectomy: A consort-prospective, randomized, controlled trial. World J Clin Cases 2021; 9:7762-7771. [PMID: 34621826 PMCID: PMC8462239 DOI: 10.12998/wjcc.v9.i26.7762] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Revised: 07/03/2021] [Accepted: 07/22/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Postoperative ileus is a frequent postoperative complication, especially after abdominal surgery. Sympathetic excitation is the primary factor for postoperative ileus. Sympathetic activation becomes increased by surgical stress, postoperative pain, and inflammation. Dexmedetomidine (DEX) can inhibit sympathetic nerve activity, inflammation, and pain.
AIM To observe whether DEX promotes bowel movements in patients after laparoscopic nephrectomy.
METHODS One hundred and twenty patients undergoing laparoscopic nephrectomy were assigned to three groups: C (normal saline infusion), D1 (DEX 0.02 µg/kg/h), and D2 (DEX 0.04 µg/kg/h). The primary outcomes were the recorded times to first flatus, defecation, and eating after surgery. The secondary outcomes were postoperative pain, assessed using the numerical rating scale (NRS), adverse effects, and the duration of the postoperative hospital stay.
RESULTS The times to first flatus, defecation, and eating in groups D1 and D2 were significantly shorter than those in group C (P < 0.01). The NRS scores at 8 h and 24 h after surgery were significantly lower in groups D1 and D2 than in group C (P < 0.05). No adverse effects were observed (P > 0.05).
CONCLUSION Postoperative infusion of DEX at 0.04 µg/kg/h facilitates bowel movements in patients undergoing laparoscopic nephrectomy.

Abstract
Background/aim This study aimed to evaluate the effect of low- and high-pressure pneumoperitoneum pressures applied during robotic-assisted laparoscopic prostatectomy (RALP) using near-infrared spectroscopy (NIRS) on regional cerebral oxygenation saturation (rSO2). Materials and methods The prospective, comparative, and observational study included patients aged 18–80 years, with the American Society of Anesthesiologists (ASA) physical status I-II, who would undergo elective RALP. The patients were divided into two groups (12 mmHg of pneumoperitoneum pressure group, n=22 and 15 mmHg of pneumoperitoneum pressure group, n=23). Patients’ demographic data, durations of anesthesia, surgery, pneumoperitoneum, and Trendelenburg position, intraoperative estimated blood loss, fluid therapy, urine output, hemodynamic and respiratory data, and rSO2 values were recorded at regular intervals. Results The rSO2 values increased significantly during the pneumoperitoneum combined with steep Trendelenburg position (from
t3
to
t6
) and at the end of the surgery (
t7
) in both groups, compared to the values 5 min after the onset of pneumoperitoneum in the supine position (
t2
) (P < 0.05), but no statistical significance was observed between the two groups. No cerebral desaturation was observed in any of our patients. Hemodynamic and respiratory parameters were preserved in both groups. The blood lactate levels were significantly higher in patients operated at high-pressure pneumoperitoneum, compared to those with low-pressure pneumoperitoneum (P < 0.05). Conclusion We believe that low-pressure pneumoperitoneum, especially in robotic surgeries, such as robotic-assisted laparoscopic prostatectomy (RALP), can be applied safely.

Abstract
Background: To evaluate intraoperative and postoperative cytokines in patients who underwent robotic prostatectomy (RP) at a pressure of 12 or 15 mm Hg, and the risk of postoperative ileus. Materials and methods: We presented the first series evaluating intraoperative and postoperative cytokines in patients undergoing RP at a pressure of 12 or 15 mm Hg by a single surgeon. Changes in cytokine concentrations were shown to correlate with surgical outcomes and pathological states. The study investigated the changes in cytokine concentrations (interferon-γ, tumor necrosis factor-α, interleukin-1β [IL-1β], IL-2, IL-4, IL-6, IL-12, and IL-17) at different pneumoperitoneum pressures and their potential role in the development of postoperative ileus. Results: The data on 10 consecutive patients confirmed that a lower pneumoperitoneum pressure was associated with lower cytokine levels and a lower risk of ileus. There were increased levels of postoperative interferon-γ, tumor necrosis factor-α, IL-12p70, IL-1β, IL-2, IL-4, and IL-17a at 15 mm Hg when compared to 12 mm Hg. Conclusions: The data indicated that lower pressure RP reduced intra-/postoperative cytokine levels confirming our hypothesis. Larger patient numbers are required to further validate this but the implications of this data will benefit not only urological patients but also other speciality patients undergoing minimally invasive surgery.

Abstract
The aim of this study is to evaluate the influence of high-pressure CO2 insufflation during TaTME on the occurrence of postoperative ileus. All patients undergoing elective transanal total mesorectal excision (TaTME) between April 2015 and March 2019 were included in a prospective database. Eligible patients were adults with mid and low-level rectal cancer undergoing elective TaTME with colorectal anastomosis and diverting ileostomy, following a standardized ERAS pathway. Patients were divided into a low-pressure (LP) group, where surgery was performed with an intrabdominal CO2 pressure of 12 mmHg, and a high-pressure (HP) group, where the intrabdominal pressure reached 15 mmHg of CO2 once the two surgical fields were connected. Of 98 patients undergoing TaTME in the observed period, 74 met the inclusion criteria and were included in this study. There was no significant difference in postoperative complications between the LP and HP groups, except for postoperative ileus, which occurred in seven patients (13.2%) in the LP group and seven patients (33.3%) in the HP group (p value 0.046). The logistic multivariate analysis showed that a high intraabdominal CO2 pressure (OR 7040, 95% CI 1591-31,164, p value 0.01) and male sex (OR 10,343, 95% CI 1078-99,256, p value 0.043) were significantly associated with postoperative ileus after TaTME. Intraabdominal CO2 pressure should be carefully set, as it may represent a risk factor for postoperative ileus in patients undergoing TaTME.

Abstract
Postoperative ileus (POI) and postoperative gastrointestinal tract dysfunction (POGD) are well-known complications affecting patients undergoing intestinal surgery. GI symptoms include nausea, vomiting, pain, abdominal distention, bloating, and constipation. These iatrogenic disorders are associated with extended hospitalizations, increased morbidity, and health care costs into the billions and current therapeutic strategies are limited. This is a narrative review focused on recent concepts in the pathogenesis of POI and POGD, pipeline drugs or approaches to treatment. Mechanisms, cellular targets and pathways implicated in the pathogenesis include gut surgical manipulation and surgical trauma, neuroinflammation, reactive enteric glia, macrophages, mast cells, monocytes, neutrophils and ICC's. The precise interactions between immune, inflammatory, neural and glial cells are not well understood. Reactive enteric glial cells are an emerging therapeutic target that is under intense investigation for enteric neuropathies, GI dysmotility and POI. Our review emphasizes current therapeutic strategies, starting with the implementation of colorectal enhanced recovery after surgery protocols to protect against POI and POGD. However, despite colorectal enhanced recovery after surgery, it remains a significant medical problem and burden on the healthcare system. Over 100 pipeline drugs or treatments are listed in Clin.Trials.gov. These include 5HT4R agonists (Prucalopride and TAK 954), vagus nerve stimulation of the ENS-macrophage nAChR cholinergic pathway, acupuncture, herbal medications, peripheral acting opioid antagonists (Alvimopen, Methlnaltexone, Naldemedine), anti-bloating/flatulence drugs (Simethiocone), a ghreline prokinetic agonist (Ulimovelin), drinking coffee, and nicotine chewing gum. A better understanding of the pathogenic mechanisms for short and long-term outcomes is necessary before we can develop better prophylactic and treatment strategies.

Abstract
BACKGROUND Robotic surgery has revolutionized postoperative outcomes across surgical specialties. However, the use of pneumoperitoneum comes with known risks given the change in physiological parameters that accompany its utilization. A recent internal review found a 7% decrease in postoperative ileus rates when utilizing a pneumoperitoneum of 12 mmHg over the standard 15 mmHg in robotic assisted radical prostatectomies (RARP). OBJECTIVE The purpose of this study is to prospectively evaluate the utility of lower pressure pneumoperitoneum by comparing 8 mmHg and 12 mmHg during RARP. DESIGN, SETTING AND PARTCIPANTS Patients were randomly assigned to undergo robotic assisted radical prostatectomy at a pneumoperitoneum pressure of 12 mmHg or 8 mmHg. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary outcome was development of postoperative ileus and secondary outcomes were length of operation, estimated blood loss and positive surgical margin status. RESULTS AND LIMITATIONS A total of 201 patients were analyzed; 96 patients at 8 mmHg and 105 patients at 12 mmHg. The groups were adequately matched as there were no differences between demographic parameters or medical comorbidities. There was a decrease in postoperative ileus rates with lower pneumoperitoneum pressures; 2% at 8 mmHg and 4.8% at 12 mmHg. There were no clinically significant differences in estimated blood loss, total length of operative time and positive margin status. CONCLUSIONS Lower pressure pneumoperitoneum during robotic assisted radical prostatectomy is non-inferior to higher pressure pneumoperitoneum levels and the experienced surgeon may safely perform this operation at 8 mmHg to take advantage of the proposed benefits.

Abstract
OBJECTIVE To evaluate perioperative complications for open radical prostatectomy (ORP) and robot-assisted RP (RARP) for patients enrolled in the PREvention of VENous ThromboEmbolism Following Radical Prostatectomy (PREVENTER; ClinicalTrials.gov Identifier: NCT03006562) trial, to determine predictors and impact on opioid consumption. PATIENTS AND METHODS A prospective cohort of 500 patients undergoing ORP and RARP was followed to determine rates of complications and opioid use. Complications were classified 30 days after RP using the Clavien-Dindo system. Patient characteristics and outcomes were compared using appropriate statistical tests. Logistic and linear regressions were performed to identify predictors of complications and evaluate the relationship between complications and postoperative opioid use. RESULTS A total of 124 (24.8%) men underwent ORP and 376 (75.2%) RARP, with 418 (83.6%) receiving pelvic lymph node dissection (PLND). While 83 patients (16.6%) had complications, only 19 (3.8%) were major (Clavien-Dindo Grade ≥III), with no differences by surgical approach. PLND (odds ratio [OR] 2.96, 95% confidence interval [CI] 1.25-8.71; P = 0.03) and Stage pT3b (OR 2.76, 95% CI 1.23-6.00;P = 0.01) were the only predictors of complications after controlling for potential confounders. Patients who had complications had greater inpatient (P = 0.02) and outpatient (P = 0.005) opioid use, which persisted after controlling for patient-reported pain, attending surgeon variation, surgical approach, and undergoing PLND (inpatient β:77.2, 95% CI 17.9-136.5,P = 0.03; and outpatient β:21.9, 95% CI 4.7-39.1,P = 0.01). CONCLUSION In an analysis of prospectively collected data, overall and major complications rates did not differ by surgical approach. Patients receiving PLND and with Stage pT3b disease had more complications. Complications were independently associated with higher inpatient and outpatient postoperative opioid use.

Abstract
Abstract
Background
It remains uncertain whether individualization of pneumoperitoneum pressures during laparoscopic surgery improves postoperative recovery. This study compared an individualized pneumoperitoneum pressure (IPP) strategy with a standard pneumoperitoneum pressure (SPP) strategy with respect to postoperative recovery after laparoscopic colorectal surgery.
Methods
This was a multicentre RCT. The IPP strategy comprised modified patient positioning, deep neuromuscular blockade, and abdominal wall prestretching targeting the lowest intra-abdominal pressure (IAP) that maintained acceptable workspace. The SPP strategy comprised patient positioning according to the surgeon's preference, moderate neuromuscular blockade and a fixed IAP of 12 mmHg. The primary endpoint was physiological postoperative recovery, assessed by means of the Postoperative Quality of Recovery Scale. Secondary endpoints included recovery in other domains and overall recovery, the occurrence of intraoperative and postoperative complications, duration of hospital stay, and plasma markers of inflammation up to postoperative day 3.
Results
Of 166 patients, 85 received an IPP strategy and 81 an SPP strategy. The IPP strategy was associated with a higher probability of physiological recovery (odds ratio (OR) 2·77, 95 per cent c.i. 1·19 to 6·40, P = 0·017; risk ratio (RR) 1·82, 1·79 to 1·87, P = 0·049). The IPP strategy was also associated with a higher probability of emotional (P = 0·013) and overall (P = 0·011) recovery. Intraoperative adverse events were less frequent with the IPP strategy (P < 0·001) and the plasma neutrophil–lymphocyte ratio was lower (P = 0·029). Other endpoints were not affected.
Conclusion
In this cohort of patients undergoing laparoscopic colorectal surgery, an IPP strategy was associated with faster recovery, fewer intraoperative complications and less inflammation than an SPP strategy. Registration number: NCT02773173 (http://www.clinicaltrials.gov).

Abstract
Background Single port (SP) robotic assisted laparoscopic surgery was approved by the FDA for urologic surgery and clinically available in 2018. This new robotic system enables a camera and 3 separate instruments, with fully wristed motions, to be placed through a single 25 mm port. This system was designed to perform complex surgery in narrow deep spaces making it very suitable for complex urinary tract reconstruction surgery. This paper will describe our early experience of using the SP system for several types of urinary reconstruction procedures and will present our lessons learned, surgical philosophy to using the SP and early data. As with all new technologies, there is an associated learning curve and nuances to be discovered and overcome. Methods The da Vinici SP™ surgical system was acquired and delivered to at our institution in January 2019. Five high volume robotic urologic surgeons at our institutions underwent certification with the da Vinci SP™ and have been adding this technology into their armamentarium. Almost all cases were recorded for quality improvement initiatives and evaluated with the goal of creating standard operating procedures in terms of access, steps of procedure and minimizing pit falls. Data from all patients undergoing SP urinary tract reconstruction that were entered into our prospective institutional database were reported. Results From 1/2019 to 8/2019 we have performed 71 urologic SP cases with the SP of which 18 were for urinary tract reconstructive procedures. These cases included 15 pyeloplasties, 1 buccal mucosa ureteroplasty, 1 ureteral implant and 1 repair of vesico-vaginal fistula. This paper outlines our standard operating procedures for table positioning, port placement, access and surgical steps for these complex SP cases. Our early data suggests that use of the SP system for urinary reconstruction is safe and reproducible. Conclusions The SP robotic surgical system has the potential to be used for nearly all robotic urologic reconstructive procedures. Advantages include a superior cosmetic result and ability to access all surgical quadrants without re-docking or repositioning. Limitations include no near infrared fluorescence imaging, smaller working space and slightly increased difficulty with retraction. We believe these obstacles will be overcome with time and experience. The da Vinci SP™ surgical system, in our initial experience, appears to be as safe and effective as its multiport counterpart for reconstructive surgeries.
