Single-incision laparoscopic surgery (SILS) for the treatment of ileocolonic Crohn's disease: a propensity score-matched analysis

Predicting conversion to tailor patient expectations and perioperative pain management in ileocecal resection for Crohn's disease

This study aims to identify risk factors of conversion to open surgery for patients undergoing minimally invasive surgery for their CD and to develop a predictive scoring system. Data from patients undergoing minimally invasive resection for their CD were collected in two European referral centers. The scoring system was developed from a logistic regression model including clinical and operative variables and its performance was evaluated using receiver operating characteristics (ROC) area under the curve (AUC). The study included 309 patients including surgery for recurrence. Conversion to open surgery occurred in 21% (65/309) of patients. The logistic regression analysis identified male sex, BMI, preoperative evidence of multiple disease localizations and abscess or perforation, and previous surgery for CD as independent risk factors for conversion. The risk score values in the converted group were significantly higher compared to non-converted group (MD = - 20.40; 95%CI - 14.12 to - 26.69; p < 0.0001). In the ROC analysis, the score achieved an AUC of 0.80 (SE = 0.03; 95%CI 0.74-0.86; p < 0.0001). Male sex, BMI, preoperative evidence of multiple disease localizations and abscess or perforation, and previous surgery for CD were associated with an increased risk of conversion to open surgical approach in patients undergoing minimally invasive surgery and were used to develop a predictive score. The results of this study might be useful to tailor patient expectations and perioperative pain management in ileocecal resection for Crohn's disease.

The Role of Minimally Invasive Surgery in the Management of Inflammatory Bowel Disease: Current Trends and Future Directions

Minimally invasive surgery (MIS) provides superior results in the surgical treatment of inflammatory bowel disease (IBD). There exist various minimally invasive procedures, each possessing its own set of benefits and drawbacks. This literature review outlines these methodologies and underscores their importance in enhancing the outcomes of patients with IBD. A grand total of 192 studies were carefully chosen and succinctly summarized. Conventional multiport laparoscopy is the most widely used MIS for IBD, with single-incision laparoscopy showing even better results. Robotic surgery offers comparable results but at higher costs and longer operation times. In the future, there will be widespread acceptance of single-incision laparoscopy and robotic surgery due to improved training and reduced expenses. Further research into the technology's utility in different IBD presentations could increase its usage.

Perioperative outcomes for single-port robotic versus single-incision laparoscopic surgery: a comparative analysis in colorectal cancer surgery

BACKGROUND

Single-incision laparoscopic surgery (SILS) may offer improved cosmesis, reduced postoperative pain and faster recovery than conventional platforms, but widespread implementation was limited by technical demands. A single-port robotic platform was recently introduced, with components that further enhance SILS benefits without the technical challenges. No study to date has compared the two platforms to validate benefits. Our goal was to compare outcomes of SP robotics and SILS in colorectal cancer (CRC).

METHODS

A prospective cancer registry was reviewed for CRC patients undergoing curative resection through a SILS or SP robotic approach from 2010 to 2022. Patient and cancer demographics, intraoperative, and postoperative outcomes were compared in a 1:1 propensity score-matched cohort, adjusting for baseline characteristics. The main outcome measures were complications, operative time, and oncologic quality measures.

RESULTS

Matching resulted 50 SP robotic and 50 SILS patients. Cohorts were well matched in all demographics, but SP robotic rectal cancer cases were significantly closer to the anorectal ring than SILS (1.8 cm vs. 3.4 cm, p = 0.018). SP robotic and SILS platforms had similar operative times. Intraoperative conversions was comparable, but more SILS cases required additional ports to be placed (p = 0.040). The intraoperative complications rate, complete total mesorectal excision rates, and lymph node yield were not statistically significantly different. There were no positive margins in either group. Postoperatively, groups had analogous day of return of bowel function, comparable morbidity, and discharge destination. There was no mortality in either group. The length of stay was significantly shorter with SP robotics than SILS (mean 4.135 vs. 5.282 days, median 4 (2-8) vs. 5 (2-14) days; p = 0.045).

CONCLUSIONS

Single-port robotics provided high quality oncologic surgery, adding the technical benefits of robotics to clinical and cosmetic benefits of single-port surgery. There were comparable operative time, complication rates, and oncologic outcomes in CRC cases, with shorter hospital stays with SP robotics. This early data is encouraging for expansion SP robotic technology.

Single-incision versus multi-port laparoscopic ileocolic resections for Crohn's disease: Systematic review and meta-analysis

Introduction

The aim of this systematic review and meta-analysis is to compare the outcomes of single-incision laparoscopic surgery (SILS) versus multi-port laparoscopy for ileocolic resection in patients with Crohn's disease (CD).

Patients and Methods

A systematic search of multiple electronic databases was conducted. The peri- and post-operative outcomes were evaluated between Crohn's patients undergoing SILS versus multi-port laparoscopy for ileocolic resection. The primary outcomes included operative time, anastomotic leak rate, post-operative wound infections and length of hospital stay. Analysed secondary outcomes were conversion rates, ileus occurrence, intra-abdominal abscess formation, return to theatre and re-admissions. Revman 5.3 was used to perform the statistical analysis.

Results

Five observational studies with 521 patients (SILS: 211; multi-port: 310) were included in the data synthesis. Patients undergoing SILS had a reduced total operative time compared to multi-port laparoscopy (mean difference [MD]: -16.14, 95% confidence interval: [CI] -27.23 - 5.05, P = 0.004). Post-operative hospital stay was also found to be significantly less in the SILS group (MD: -0.57, 95% CI: -0.73--0.42, P < 0.0001). No significant difference was seen in the anastomotic leak rate (MD: -16.14, 95% CI: 0.18-1.71, P = 0.004) or post-operative wound infections (odds ratio: 0.78, 95% CI: 0.24 - 2.47, P = 0.67) between the two groups. Moreover, all the measured secondary outcomes were comparable.

Conclusion

SILS seems to be a feasible alternative to multi-port laparoscopic surgery for ileocolic resection in patients with CD. Improved outcomes in terms of total operative time and length of hospital stay were observed in patients undergoing SILS surgery. Adopting this procedure into routine clinical practice constitutes the next step in the development of minimally invasive surgery.

Minimally invasive surgery in Crohn's disease: state-of-the-art review

Surgery for Crohn's disease (CD) has undergone significant advancements over the last two decades, especially minimally invasive surgery. In addition to its feasibility and safety, minimally invasive surgery provides manifold advantages, including a decreased hospitalization duration, improved aesthetic results, and fewer occurrences of intra-abdominal adhesions. Due to the special intraoperative characteristics of CD, such as chronic inflammation, a thickened mesentery, fistulas, abscesses and large masses, a minimally invasive approach seems to be challenging. Complete implementation of this technique for complex disease has yet to be studied. In this review, we provide a review on the applicability of minimally invasive surgery in CD and future perspectives for the technical advances in the field.

Comparison of laparoscopic and open ileocecal resection for Crohn's disease in children

PURPOSE

Ileocecal resection (ICR) is the most frequently performed surgery in paediatric Crohn's disease (CD) patients. The aim of the study was to compare laparoscopic-assisted and open ICR.

METHODS

Retrospective review of consecutive CD patients undergoing ICR between March 2014 and December 2021 was performed. The patients were divided into open (OG) and laparoscopic (LG) groups. Compared parameters included patients' demographics, clinical characteristics, surgery, duration of hospitalisation and follow-up. Complications were classified according to the Clavien-Dindo classification (CDc). Risk factors were identified using multivariable analysis.

RESULTS

Sixty-two patients (29 females, 46.7%) were included in the analysis, forty-two patients in OG. The median duration of surgery was 130 in OG versus 148 in LG (p = 0.065) minutes. Postoperative complications were reported in 4 patients (12.1%). There was no significant difference in postoperative complications according to CDc (OG 7.14 vs LG 5%, p = 1). The median length of hospitalisation was 8 in OG and 7 days in LG (p = 0.0005). The median length of follow-up was 21.5 months.

CONCLUSION

The laparoscopic-assisted approach had shorter hospital stay and was not associated with increased risk of 30-day postoperative complications. Laparoscopic surgery should be considered the preferred surgical approach for primary ICR.

Targeting P2 receptors in purinergic signaling: a new strategy of active ingredients in traditional Chinese herbals for diseases treatment

Adenosine triphosphate (ATP) and its metabolites adenosine diphosphate, adenosine monophosphate, and adenosine in purinergic signaling pathway play important roles in many diseases. Activation of P2 receptors (P2R) channels and subsequent membrane depolarization can induce accumulation of extracellular ATP, and furtherly cause kinds of diseases, such as pain- and immune-related diseases, cardiac dysfunction, and tumorigenesis. Active ingredients of traditional Chinese herbals which exhibit superior pharmacological activities on diversified P2R channels have been considered as an alternative strategy of disease treatment. Experimental evidence of potential ingredients in Chinese herbs targeting P2R and their pharmacological activities were outlined in the study.
