A comparative study of single-incision versus conventional multiport laparoscopic ileocecal resection for Crohn's disease with strictures

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.

A Systematic Review of Comparing Single-incision Versus Traditional Laparoscopic Right Hemicolectomy For Right Colon Diseases

BACKGROUND

Single-incision laparoscopic right hemicolectomy (SILS) has been promoted in clinic since 2008, but a systematic review of comparing SILS and traditional laparoscopic right hemicolectomy (TLS) with long-term follow-up is rare. Here, in this study, comparison of SILS and TLS with long-term follow-up was evaluated by a meta-analysis method.

METHODS

All studies about SILS and TLS for right hemicolectomy from 2010 to 2018 were searched from databases including Medline, Embase, Cochrane Library, and Wanfang. Operation index, recovery, and midterm follow-up data were evaluated by fixed-effects models, random-effects models, and Begg test.

RESULTS

We collected 22 studies with 2218 patients. SILS groups contained 1038 (46.7%) patients, and 1180 (53.3%) patients were observed in the TLS group. Patients' baseline data were similar in the 2 groups. Compared with TLS, SILS had shorter operation duration [standardized mean difference (SMD): -0.35, 95% confidence interval (CI): -0.61 to -0.08, P<0.001, χ=49.40], shorter hospitalization time (SMD: -0.27, 95% CI: -0.37 to -0.16, P<0.001, χ=9.17), slightly less blood loss (SMD: -0.23, 95% CI: -0.36 to -0.10; P<0.001; χ=5.36), and smaller incision length (SMD: -2.19, 95% CI: -3.66 to -0.71, P<0.001; χ=316.1). No statistical differences were observed in other figures.

CONCLUSION

SILS is more convenient and has better efficacy than TLS and could provide a promising surgical approach for right colon diseases.

A review of reports on single-incision laparoscopic surgery for Crohn's disease

The aim of this review was to analyze the currently available literature on single-incision laparoscopic surgery (SILS) for Crohn's disease (CD) with respect to surgical indications, surgical techniques, feasibility, and possible benefits of SILS for CD. A systematic query of articles published from January 2010 to July 2018 was performed. The studies were assessed for patient's age, gender, body mass index, disease type, SILS procedure, surgical procedure, incision length, operation time, rates of conversion to open surgery, postoperative complications, mortality, length of hospital stay, and rates of reoperation. After an initial review, 11 reports were selected. The surgical techniques and instruments showed wide variation. The mean operation time for SILS tended to be shorter than that for multiport laparoscopic surgery (MLS). The reported rates of conversion to open surgery and postoperative complications were not very different from those reported for MLS. In conclusion, the present review suggests that the SILS technique may be feasible and safe for select patients with CD. However, because we reviewed only a few studies with small sample sizes, prospectively designed trials with a large number of patients are required to clarify the true benefits of SILS for CD.

Changing trends in surgery for abdominal Crohn's disease

AIM

The introduction of biological agents and laparoscopy are, arguably, the most important developments for the treatment of Crohn's disease (CD) in the last two decades. Due to the efficacy of biological agents in treating mild disease, it is likely that the percentage of surgery for complex cases may have increased. The objective of this study was to analyse the changing characteristics and results of the surgical treatment of patients with CD over the past 13 years.

METHODS

All patients who underwent abdominal surgery for CD between 2004 and 2016 were retrospectively identified. Data were compared between two periods (2004-2010 and 2011-2016).

RESULTS

A total of 908 procedures were performed (48% men, mean age 43 ± 16 years). Demographic and CD characteristics changed significantly over time: comorbidities were more frequent (35% vs 46%, P < 0.0001), and preoperative steroids (28% vs 36%, P < 0.01) and anti-tumour necrosis factor (20% vs 40%, P < 0.0001) treatments were more frequently used in the second period. Smoking (14% vs 8%, P < 0.0001) and use of immunosuppressors (32% vs 22%, P < 0.001) decreased significantly. More cases of penetrating disease (22% vs 32%, P < 0.001) were operated upon in the second period. The laparoscopic approach (49% vs 57%, P < 0.04) was more frequently performed and mean blood loss (167 ± 222 vs 123 ± 243 ml, P < 0.01) decreased significantly. Postoperative morbidity did not change between the two periods.

CONCLUSION

Despite a higher incidence of comorbidities and the use of biologics postoperative morbidity remained unchanged. An increased use of laparoscopy and a decreased intra-operative blood loss may have contributed to offsetting the impact of increased comorbidity.

Laparoscopic left lateral sectionectomy: A three-port method

Background

Laparoscopic liver resection has become popular recent years. Laparoscopic left lateral sectionectomy (LLS) is now a standard operation with sufficient safety and feasibility. To improve the benefits of minimally invasive surgery, we invented and have been performing a reduced port LLS procedure using 3 ports since 2009.

Materials and Methods

All patients who underwent LLS at Toranomon Hospital (Tokyo, Japan) were included, except for patients with a previous history of upper abdominal surgery or those who had undergone the simultaneous resection of another organ. An essential point of this procedure was the extracorporeal traction of the divided round ligament using a ligature. As a result, the operator was able to perform the parenchymal transection within a good operative field.

Results

Twelve patients were enrolled in the study. All the patients had a Child-Pugh classification of Class A. The median indocyanine green retention rate at 15 min was 9.5%. Compared with previously reported results for conventional LLS, the median operation time (82.5 min), blood loss (0 mL) and rate of blood transfusion (0%) were lower for the 3-port LLS procedure. The rates of complications (9%) and a positive surgical margin (0%) were similar to those reported for the conventional approach.

Conclusion

Three-port LLS appears to be a safe and feasible procedure.

Comparison of Single-Port Versus Standard Multiport Left Lateral Liver Sectionectomy

It remains unclear if single incision laparoscopic liver surgery is superior to standard multiport resections and in what regard patients might benefit from this approach. We retrospectively analyzed the course of all patients undergoing laparoscopic left lateral sectionectomy at our center between 2009 and 2017. In total, 11 single incision and 31 multiport left lateral sectionectomies were performed at our center between July 2009 and May 2017. Six patients were excluded due to multivisceral resections. Indications included adenoma (n = 7 vs n = 2), focal nodular hyperplasia (n = 4 vs n = 3), hepatocellular carcinoma (n = 4 vs n = 4), colorectal liver metastasis (n = 4 vs n = 0), noncolorectal metastasis (n = 2 vs n = 1), hemangioma (n = 3 vs n = 0), abscess (n = 1 vs n = 0), and cysts (n = 1 vs n = 0). Length of operation was significantly shorter in the single incision group (206 vs 137 minutes, P = .003). One complication was observed in the single incision group (grade IIIb, n = 1) while 3 patients in the multiport group suffered from postoperative complications (grade II, n = 1; grade IIIa, n = 2), resulting in a morbidity rate of 12.5% and 11.5%, respectively. No mortality was observed in both groups. Length of hospital stay did not significantly differ in both groups (median 7 vs 7 days, P = .513). The single incision approach is safe and has become the standard approach for the left lateral sectionectomy at our center. Shorter operation times technique might well be due to the easy retrieval of the liver specimen via the umbilical incision with no need for a Pfannenstiel incision.

Single port laparoscopic ileocaecal resection for Crohn's disease: a multicentre comparison with multi-port laparoscopy

AIM

Single port (SP) ileocaecal resection (ICR) is an established technique but there are no large studies comparing SP and multi-port (MP) laparoscopic surgery in Crohn's disease (CD). The aim of this study was to compare postoperative pain scores and analgesia requirements after SP and MP laparoscopic ICR for CD.

METHOD

This was a retrospective study of patients undergoing SP or MP ICR for CD in three tertiary referral centres from February 1999 to October 2014. Baseline characteristics (age, sex, body mass index and indication for surgery) were compared. Primary end-points were postoperative pain scores, analgesia requirements and short-term postoperative outcomes.

RESULTS

SP ICR (n = 101) and MP ICR (n = 156) patients were included in the study. Visual analogue scale scores were significantly lower after SP ICR on postoperative day 1 (P = 0.016) and day 2 (P = 0.04). Analgesia requirements were significantly reduced on postoperative day 2 in the SP group compared with the MP group (P = 0.007). Duration of surgery, conversion to open surgery and stoma rates were comparable between the two groups. Surgery was more complex in terms of additional procedures when MP was adopted (P = 0.001). There were no differences in postoperative complication rates, postoperative food intake, length of stay and readmissions.

CONCLUSION

These data suggest that in comparison to standard laparoscopic surgery SP ICR might be less painful and patients might require less opioid analgesia.

The Role of the Single Incision Laparoscopic Approach in Liver and Pancreatic Resectional Surgery

Introduction. Single incision laparoscopic surgery (SILS) has gained increasing support over the last few years. The aim of this narrative review is to analyse the published evidence on the use and potential benefits of SILS in hepatic and pancreatic resectional surgery for benign and malignant pathology. Methods. Pubmed and Embase databases were searched using the search terms “single incision laparoscopic”, “single port laparoscopic”, “liver surgery”, and “pancreas surgery”. Results. Twenty relevant manuscripts for liver and 9 for pancreatic SILS resections were identified. With regard to liver surgery, despite the lack of comparative studies with other minimal invasive techniques, outcomes have been acceptable when certain limitations are taken into account. For pancreatic resections, when compared to the conventional laparoscopic approach, SILS produced comparable results with regard to intra- and postoperative parameters, including length of hospitalisation and complications. Similarly, the results were comparable to robotic pancreatectomies, with the exception of the longer operative time reported with the robotic approach. Discussion. Despite the limitations, the published evidence supports that SILS is safe and feasible for liver and pancreatic resections when performed by experienced teams in the tertiary setting. However, no substantial benefit has been identified yet, especially compared to other minimal invasive techniques.

European Crohn's and Colitis Organisation Topical Review on Prediction, Diagnosis and Management of Fibrostenosing Crohn's Disease

Single-incision laparoscopic surgery (SILS) for children with Crohn's disease

PURPOSE

Single-incision laparoscopic surgery (SILS) has been described in adults with Crohn's disease, but its use in pediatric Crohn's patients has been limited. The purpose of this study was to review our experience with SILS in pediatric patients with Crohn's disease.

METHODS

A retrospective review was performed for patients diagnosed with Crohn's disease who underwent small bowel resection or ileocecectomy at a freestanding children's hospital from 2006 to 2014. Data collected included demographic data, interval from diagnosis to surgery, operative time, length of stay, and postoperative outcomes.

RESULTS

Analysis identified 19 patients who underwent open surgery (OS) and 41 patients who underwent SILS. One patient (2.4 %) within the SILS group required conversion to OS. Demographic characteristics were similar between the 2 cohorts. The most common indication for surgery was stricture/obstruction (SILS 70.7 % vs. OS 68.4 %, p = 0.86), and ileocecectomy was the most common primary procedure performed (SILS 90.2 % vs. OS 100 % OS). Operative times were longer for SILS (135 ± 50 vs. 105 ± 37 min, p = 0.02). However, when the last 20 SILS cases were compared to all OS cases, the difference was no longer statistically significant (SILS 123.3 ± 34.2 vs. OS 105 ± 36.5, p = 0.12). No difference was noted in postoperative length of stay (SILS 6.5 ± 2.2 days vs. OS 7.4 ± 2.2 days, p = 0.16) or overall complication rate (SILS 24.4 % vs. OS 26.3 %, p = 0.16).

CONCLUSION

SILS ileocecectomy is feasible in pediatric patients with Crohn's disease, achieving outcomes similar to OS. As experience increased, operative times also became comparable.

Advances in reduced port laparoscopic liver resection

Reduced port surgery has been attracting attention in the field of minimally invasive surgery. Although the use of SILS is becoming widespread, technical difficulty has delayed its adoption for laparoscopic liver resection. Recently, advances in laparoscopic liver resection have been made in tandem with advances in surgical skill and devices. The main driver in conventional laparoscopic liver resection's evolution to become less surgically invasive seems to be single-incision laparoscopic liver resection (SILLR). To date, most reports on SILLR have been single case reports or case series. Only a few cohort studies on conventional laparoscopic surgery and SILLR have been conducted. Recent reports have described the use of SILLR for well-localized lesions and solitary tumors located in the anterolateral segments of the liver or left liver lobe, but its application remains limited to partial resection and left lateral sectionectomy. The feasibility and safety of SILLR have been demonstrated, but additional work is needed for standardization of the procedure.

Laparoscopic surgery in the management of Crohn's disease

Crohn’s disease is a chronic inflammatory bowel disease with surgery still frequently necessary in its treatment. Since the 1990’s, laparoscopic surgery has become increasingly common for primary resections in patients with Crohn’s disease and has now become the standard of care. Studies have shown no difference in recurrence rates when compared to open surgery and benefits include shorter hospital stay, lower rates of wound infection and decreased time to bowel function. This review highlights studies comparing the laparoscopic approach to the open approach in specific situations, including cases of complicated Crohn’s disease.

Single-incision laparoscopic ileocecectomy in children with Crohn's disease

INTRODUCTION

We previously reported our experience with standard laparoscopic ileocecectomy, but we have recently used a single-incision laparoscopic approach.

PATIENTS AND METHODS

We conducted a retrospective review of a single surgeon's experience from 2009 to 2013.

RESULTS

Twenty-eight children 11-18 years of age (mean, 15.5 years) with a mean body mass index of 18.9±3 kg/m(2) underwent single-incision laparoscopic ileocecectomy for Crohn's disease. Mean operative time was 86.5±25.9 minutes (range, 56-166 minutes). There were no extra ports placed or conversions to open surgery. Five children (18%) were on parenteral nutrition at time of surgery, 14 (50%) were on steroids, and 9 (32%) were on tumor necrotic factor inhibitors. A stapled extracorporeal anastomosis was performed in all children. Complications included abscess (n=4), small bowel obstruction (n=3), superficial wound infection (n=3), and small bowel perforation (n=1). Some patients had more than one complication. Of those with complications, 5 (56%) were on steroids, 5 (56%) were on tumor necrotic factor inhibitors, and 1 patient was on both. The perforation occurred at a point of adhesiolysis also involved with Crohn's disease. There were no anastomotic leaks. Median follow-up was 17 months (range, 1-47 months).

CONCLUSIONS

Single-incision laparoscopic ileocecectomy is safe and feasible in pediatric patients with Crohn's disease.

Single-port versus multiport laparoscopic ileocecal resection for Crohn's disease

BACKGROUND AND AIMS

Several case series have demonstrated the feasibility of single-port laparoscopic ileocecal resection in Crohn's disease. However, only a few studies compared the single-port with a multiport laparoscopic ileocecal approach. The aim of this study was to compare short term surgical outcome parameters between single-port and multiport laparoscopic ileocecal resections for Crohn's disease.

METHODS

Twenty-one patients who underwent single-port laparoscopic ileocecal resection between March 2010 and September 2012 were prospectively registered. A matched comparison on a 1:2 basis was performed with patients who underwent multiport laparoscopic ileocecal resection from January 1999 to March 2010. Matching parameters were BMI, length of diseased bowel resected and the presence of fistulas. Endpoints were the length of postoperative hospital stay, operative time, conversions, complications, postoperative pain scores and postoperative analgesia consumption.

RESULTS

Twenty-one patients undergoing single-port resection were matched to 42 patients undergoing multiport resection. The postoperative stay (4 days, iqr 4-5 vs. 5 days, iqr 4-6; p=0.033), operative time (103 min, iqr 94.0-121.0 vs. 123.5 min, iqr 100.0-157.0; p=0.036) and morphine use on the first postoperative day (12.5 mg, iqr 5.0-33.3 vs. 28 mg, 15.0-50.0; p=0.012) differed significantly. Postoperative pain scores and complications were similar in both groups. This study was limited by potential selection bias.

CONCLUSIONS

Single-port laparoscopic ileocecal resection is safe and feasible in Crohn's disease and is associated with less need for pain medication postoperatively as opposed to multiport laparoscopic ileocecal resection.

A Technique of Single-Incision Laparoscopic Appendectomy Using Conventional Multiport Laparoscopic Instruments (SILACI): Preliminary Experience of 32 Cases

Single-incision laparoscopic appendectomy seeks to further reduce the trauma of parietal access to abdomen. The challenge of this surgery lies in the compromised ergonomics of instrument movement and triangulation. In this context, a feasibility study of an operative technique of single-incision laparoscopic appendectomy with technical modifications was conducted. This prospective study was carried out in tertiary care teaching institute of a semi-urban area in South India over a period of 1 year from June 2010 to May 2011. Thirty-two patients of acute appendicitis were included in this study. Mean operative time was 56.7 min (40-85 min). Mean age of subjects was 41 ± 15 years. M/F ratio was 2:1. There was no significant peri-operative morbidity or mortality. Mean follow-up period was 8 months. We propose that this technique of single-incision laparoscopic appendectomy using conventional multiport laparoscopic instruments (SILACI) is feasible, safe, and cost-effective.
