Laparoscopic ileocecal resection in Crohn's disease: a case-matched comparison with open resection

Redo Ileocolic Resection Is Not an Independent Risk Factor for Anastomotic Leak in Recurrent Crohn's Disease

BACKGROUND

Redo ileocolic resection for recurrent Crohn's disease is associated with increased technical complexity and higher complication rates compared to primary resection. Literature concerning redo surgery for recurrent Crohn's disease is scarce and it is controversial whether a redo is a risk factor for postoperative anastomotic leak.

OBJECTIVE

This study aimed to hypothesized that redo ileocolic resection for Crohn's disease is an independent risk factor for anastomotic leak.

DESIGN

Retrospective, case-control study from 1994 to 2019 with multivariate analysis and propensity score weighting.

SETTING

Quaternary, IBD-referral center.

PATIENTS

Adult patients aged >18 years were included in the study.

INTERVENTIONS

Primary or redo ileocolic resection with an anastomosis, with or without diverting ileostomy.

MAIN OUTCOME MEASURES

Thirty-day anastomotic leak rate.

RESULTS

A total of 991 patients (56% primary and 44% redo ileocolic resections) were included. Patients who underwent redo resection were significantly older with more comorbidities, fewer medications, and less fistulizing disease compared to the primary group. On univariate analysis, patients who underwent redo resection had more overall complications (50.5% vs 36.2%, p < 0.001), and the cumulative number of prior ileocolic resections was significantly associated with increased risk for overall morbidity ( p < 0.001). There were 31 (3%) anastomotic leaks; leak rates did not differ between groups ( p = 0.60). Multivariable analysis indicated that extensive adhesiolysis ( p < 0.001), ileostomy omission ( p = 0.009), and intraoperative abscess/fistula ( p = 0.02) were independently associated with leaks but not redo resection ( p = 0.27). Patients with 0, 1, 2, or 3 of these risk factors had observed leak rates of 1.1%, 1.3%, 6.0%, and 11.6.% ( p = 0.03), respectively.

LIMITATIONS

The limitations of this study were selection bias, referral bias, and single quaternary center.

CONCLUSIONS

Compared to primary procedures, redo ileocolic resection for recurrent Crohn's disease is associated with increased overall morbidity but not anastomotic leak. See Video Abstract at http://links.lww.com/DCR/C132 .

Surgical Strategies to Reduce Postoperative Recurrence of Crohn's Disease After Ileocolic Resection

Postoperative recurrence after ileocaecal resection for fibrostenotic terminal ileal Crohn's disease is a significant issue for patients as it can result in symptom recurrence and requirement for further surgery. There are very few modifiable factors, aside from smoking cessation, that can reduce the risk of postoperative recurrence. Until relatively recently, the surgical technique used for resection and anastomosis had little or no impact on postoperative recurrence rates. Novel surgical techniques such as the Kono-S anastomosis and extended mesenteric excision have shown promise as ways to reduce postoperative recurrence rates. This manuscript will review and discuss the evidence regarding a range of surgical techniques and their potential role in reducing disease recurrence. Some of the techniques have been shown to be associated with significant benefits for patients and have already been integrated into the routine clinical practice of some surgeons, while other techniques remain under investigation. Current techniques such as resection of the mesentery close to the intestine and stapled side to side anastomosis are being challenged. It is looking more likely that surgeons will have a major role to play when it comes to reducing recurrence rates for patients undergoing ileocaecal resection for Crohn's disease.

MANAGEMENT OF ILEOCECAL CROHN'S DISEASE DURING SURGICAL TREATMENT FOR ACUTE APPENDICITIS: A SYSTEMATIC REVIEW

BACKGROUND

In many patients, the diagnosis of Crohn's disease (CD) is made during surgery for appendicitis in urgent settings. Intraoperative diagnosis can be challenging in certain cases, especially for less experienced surgeons.

OBJECTIVE

Review of the literature searching for scientific evidence that can guide surgeons through optimal management of ileocecal CD found incidentally in surgery for acute appendicitis (AA).

METHODS

Included studies were identified by electronic search in the PubMed database according to the Preferred Items of Reports for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The quality and bias assessments were performed by Methodological Index for Non-Randomized Studies (MINORS) criteria for non-randomized studies.

RESULTS

A total of 313 studies were initially identified, six of which were selected (all retrospective) for qualitative assessment (two studies were comparative and four only descriptive case series). Four studies identified a high rate of complications when appendectomy or ileocolectomy were performed and in only one, there was no increased risk of postoperative complications with appendectomy. In the sixth study, diarrhea, previous abdominal pain, preoperative anemia and thrombocytopenia were independent predictors for CD in patients previously operated for suspected AA.

CONCLUSION

Despite the paucity of data and low quality of evidence, a macroscopically normal appendix should be preserved in the absence of complicated disease when CD is suspected in surgery for AA. Ileocecal resections should be reserved for complicated disease (inflammatory mass, ischemia, perforation or obstruction). Further prospective studies are needed to confirm these claims.

A scoring system to predict a prolonged length of stay after surgery for Crohn's disease

AIM

Many factors influence the postoperative length of stay (LOS) in Crohn's disease (CD). This study aims to identify the factors associated with a prolonged LOS after ileocolic resection (ICR) for CD and to develop a scoring system to predict the postoperative LOS in CD.

METHOD

Patient data were collected from St Marks Hospital, London, UK, and the Humanitas Clinical and Research Center Milan, Italy, for all patients who underwent an ICR for CD from 2005 to 2017. Logistic regression was used for multivariate analysis. The scoring system was developed from the logistic regression model. The performance of the scoring system was evaluated using the area under the receiver operating characteristic curve (AUROC).

RESULTS

A total of 628 surgeries were included in the analysis. Eighty eight surgeries were excluded due to missing data. The remaining 543 were divided into two cohorts for the development (n = 418) and validation (n = 125) of the scoring system. The regression model was statistically significant (p < 0.0001). The statistically significant independent variables included the time since diagnosis, American Society of Anesthesiologists (ASA) grade, perioperative use of steroids, surgical access, strictureplasty and platelet count. The AUROCs for the development and validation cohorts were 0.732 and 0.7, respectively (p < 0.0001). The cut-off score suggested by Youden's index was 50, with a sensitivity of 65.6% and a specificity of 73.3%.

CONCLUSION

The time since diagnosis, ASA grade, steroid use, surgical access, strictureplasty and platelet count were associated with a prolonged LOS and were used to develop a scoring system. The calculator is available online at https://rebrand.ly/Crohnscal.

Pediatric Crohn's Disease

The incidence of Crohn's disease in the pediatric population is increasing. While pediatric patients with Crohn's disease exhibit many of the characteristics of older patients, there are important differences in the clinical presentation and course of disease that can impact the clinical decisions made during treatment. The majority of children are diagnosed in the early teen years, but subgroups of very early onset and infantile Crohn's present much earlier and have a unique clinical course. Treatment paradigms follow the traditional laddered approach, but growth and development represent special considerations that must be given to pediatric-specific complications of the treatment and disease. Surgical intervention is an important component of Crohn's management and is often employed to allow improved nutritional intake or decrease reliance on medical treatments that compromise growth.

Laparoscopy for Benign Diseases of the Colon

Laparoscopic surgery has revolutionized the delivery of care to the surgical patient undergoing colorectal resection. Since the first laparoscopic-assisted colectomy in 1991, significant advances have been made in minimally invasive colorectal surgery. For many benign conditions, laparoscopic colectomy has been proven to be safe and effective, and in some instances superior when compared with open surgery. Complex laparoscopic resections such as those for diverticulitis and inflammatory bowel disease have also been shown to have equivalent outcomes when compared with open surgery. Short-term benefits of a minimally invasive approach include less pain, decreased rates of wound infection and postoperative morbidity, faster return of bowel function, and shorter length of stay. Improvements in long-term complications have also been noted with lower incidence of incisional hernias and small bowel obstructions secondary to adhesions. As surgeons become more facile with laparoscopic resection, more complex cases such as those for complicated diverticulitis and reoperative surgery for inflammatory bowel disease can be completed with shorter operative times and decreased cost.

Prognostic Nutritional Index Predicts Short-Term Postoperative Outcomes After Bowel Resection for Crohn's Disease

BACKGROUND

Bowel resection is required in the majority of patients with Crohn's disease (CD) during their lifetime. The Prognostic Nutritional Index (PNI) is a useful tool for predicting postoperative outcomes in patients undergoing cancer surgery. We examined the ability of the PNI to predict short-term outcomes in patients with CD-related bowel resection.

MATERIALS AND METHODS

Seventy-three patients who underwent bowel resection for CD were retrospectively enrolled in the study. The PNI was calculated as follows: 10 × serum albumin (g/dL) + 0.005 × total lymphocyte count (per mL). Patients were divided into 2 groups: PNI <40 (n = 30) and PNI ≥40 (n = 43).

RESULTS

A significant difference was found in body mass index (17.9 ± 2.4 vs 19.2 ± 2.2, P = .018) between the 2 groups. Postoperative overall and infectious complications occurred more frequently in patients with PNI <40 than in those with PNI ≥40 (50.0% and 46.7% vs 23.3% and 16.3%, P = .018 and P = .005, respectively). In the univariate analysis, body mass index <18.5, penetrating behavior, open surgery, and PNI <40 were associated with an increased risk of overall complications and infectious complications. In the multivariate analysis, only PNI <40 was an independent prognostic factor for infectious complications (odds ratio: 3.846, 95% confidence interval: 1.145-12.821).

CONCLUSIONS

Preoperative PNI is a useful predictor of postoperative infectious complications in patients with CD-related bowel resection.

Preoperative risk factors and radiographic findings predictive of laparoscopic conversion to open procedures in Crohn's disease

INTRODUCTION

Laparoscopy is accepted as a standard surgical approach for Crohn's disease. However, the rate of conversion is high, ranging from 15 to 70 % depending on the population. There are also concerns that conversion results in worsened outcomes versus an initial open procedure.

METHODS

This study evaluated preoperative radiographic findings to determine who is at increased risk of conversion and may therefore benefit from an initial open approach. A case-matched study included patients from 2004 to 2013 with preoperative CTE/MRE who underwent laparoscopic surgery converted to an open approach, and compared them to laparoscopically completed controls with similar age, same surgeon, and number of previous abdominal operations. Studies were reviewed by two blinded radiologists. Variables included abdominal AP diameter, amount of subcutaneous fat, peritoneal versus pelvic location of disease (greater or lesser hemipelvis or abdomen), intestinal location of disease (colon, TI, ileum, jejunum), and presence, length, and location of strictures, simple or complex fistula, phlegmon, or abscess. Conditional logistic regression evaluated relationships between radiographic variables and conversion. Twenty-seven patients meeting study criteria were compared with 81 controls.

RESULTS

A negative association between conversion and disease in the left lesser pelvis was found (p = 0.019) and neared significance for left abdomen (p = 0.08). Positive correlations were found with pelvic fistulas (p = 0.003), complex fistulas (p = 0.017), and pelvic abscesses (p = 0.009) and neared significance for Society of Abdominal Radiology classification (p = 0.058).

CONCLUSION

Preoperative imaging in patients with Crohn's disease can help in selecting the most suitable cases to approach laparoscopically and reduce conversion rates and should be evaluated in conjunction with other preoperative factors.

Laparoscopic approach for inflammatory bowel disease is a real alternative to open surgery: an experience with 574 consecutive patients

OBJECTIVE

This study aimed to report a 14-year experience of laparoscopic approach for inflammatory bowel disease (IBD), including complicated and recurrent cases.

BACKGROUND

Feasibility of laparoscopic approach for IBD surgical management has been questioned.

METHODS

From 1998 to 2012, all patients undergoing colorectal resection for IBD were prospectively enrolled. Adjusted risks of conversion and severe postoperative morbidity after laparoscopic resection were computed, according to a multivariate regression logistic model.

RESULTS

A total of 790 consecutive resections for IBD were performed on 633 patients. Laparoscopic approach was performed in 574 (73%) procedures, including 286 ileocecal resections (48%), 118 subtotal colectomies (19%), 134 ileal pouch-anal anastomoses (21%), 23 segmental colectomies (8%), and 18 abdominoperineal resections (4%). A total of 145 (25%) complex laparoscopic procedures were performed, considered as such because of iterative surgery for IBD recurrence (n = 66, 12%) or because of intra-abdominal-abscess or fistula (n = 93, 16%). Conversion to laparotomy occurred in 67 procedures (12%). Postoperative death occurred in 1 patient (0.2%). Severe postoperative morbidity occurred in 66 laparoscopic procedures (13%). Splitting the study in 5 time periods, the rate of laparoscopic procedures significantly increased from 42% in period 1 to 80% in period 5 (P < 0.001). With time, the rate of complex procedures performed laparoscopically significantly increased (P = 0.023), whereas both mean adjusted risks of conversion and severe postoperative morbidity significantly decreased (P < 0.001).

CONCLUSIONS

Laparoscopic approach is a safe and effective alternative to open surgery for IBD management. With growing experience, the rate of laparoscopic complex procedures increased, whereas adjusted risks of conversion and severe postoperative morbidity significantly decreased.

Laparoscopy in Crohn's disease

In Crohn's disease (CD) surgical management, laparoscopic approach offers several theoretical advantages over the open approach. However, the importance of inflammatory lesions associated with CD, and the frequent presence of adhesions from previous surgery have initially questioned its feasibility and safety. In the present review article we will discuss the role of laparoscopic approach for Crohn's disease surgical management, along with its potential benefits as compared to the open approach.

Preoperative magnetic resonance enterography in predicting findings and optimizing surgical approach in Crohn's disease

BACKGROUND

Many Crohn's disease patients require surgery. Intraoperative detection of new lesions may lead to change in planned surgery. This study aimed to determine whether magnetic resonance enterography can optimize surgical planning and guide decision making in Crohn's disease.

METHODS

Seventy-five patients with complicated Crohn's disease were enrolled and underwent preoperative magnetic resonance enterography. Analysis included imaging accuracy and change in surgical strategy due to discordance with imaging findings.

RESULTS

Surgery was performed laparoscopically in 39/75 patients (52 %), with conversion to open surgery required in six (15 %). Concordance between observers was excellent (kappa value >0.8). Magnetic resonance enterography accuracy for stenosis, abscess, and fistula were all above 85 % in per-patient analysis. In 68/75 cases (90.7 %) surgery was correctly predicted. Conversely, in 7/75 cases (three false-positives and four false-negatives) surgical strategy (type of resection or strictureplasty, n = 5) and/or surgical approach (conversion from laparoscopy to open surgery, n = 2) changed due to discordance with magnetic resonance enterography findings.

CONCLUSION

Surgical strategy and approach are correctly predicted by magnetic resonance enterography in the majority of patients with complicated Crohn's disease.

Laparoscopic surgery for Crohn's disease: a meta-analysis of perioperative complications and long term outcomes compared with open surgery

Background

Previous meta-analyses have had conflicting conclusions regarding the differences between laparoscopic and open techniques in patients with Crohn’s Disease. The objective of this meta-analysis was to compare outcomes in patients with Crohn’s disease undergoing laparoscopic or open surgical resection.

Methods

A literature search of EMBASE, MEDLINE, The Cochrane Central Register of Controlled Trials and the US National Institute of Health’s Clinical Trials Registry was completed. Randomized clinical trials and non-randomized comparative studies were included if laparoscopic and open surgical resections were compared. Primary outcomes assessed included perioperative complications, recurrence requiring surgery, small bowel obstruction and incisional hernia.

Results

34 studies were included in the analysis, and represented 2,519 patients. Pooled analysis showed reduced perioperative complications in patients undergoing laparoscopic resection vs. open resection (Risk Ratio 0.71, 95% CI 0.58 – 0.86, P = 0.001). There was no evidence of a difference in the rate of surgical recurrence (Rate Ratio 0.78, 95% CI 0.54 – 1.11, P = 0.17) or small bowel obstruction (Rate Ratio 0.63, 95% CI 0.28 – 1.45, P = 0.28) between techniques. There was evidence of a decrease in incisional hernia following laparoscopic surgery (Rate Ratio 0.24, 95% CI 0.07 – 0.82, P = 0.02).

Conclusions

This is the largest review in this topic. The results of this analysis are based primarily on non-randomized studies and thus have significant limitations in regards to selection bias, confounding, lack of blinding and potential publication bias. Although we found evidence of decreased perioperative complications and incisional hernia in the laparoscopic group, further randomized controlled trials, with adequate follow up, are needed before strong recommendations can be made.

Laparoscopic surgery for inflammatory bowel disease--the experience in China

BACKGROUND

The incidence of inflammatory bowel disease (IBD) has risen rapidly in China over the last 15 years. Increasing numbers of people with IBD require surgery during their lifetime, but few reports of IBD in Eastern populations have been described to date. The aim of this study was to assess the short-term effects of the laparoscopic surgery for IBD in Chinese patients.

MATERIALS AND METHODS

From February 2010 to March 2012, 35 patients with IBD underwent laparoscopic operations and the clinical data obtained for these patients were reviewed.

RESULTS

Patients with Crohn's disease (CD) (N = 21) and ulcerative colitis (UC) (N = 14) underwent laparoscopic surgery. In the CD group, the mean age was 37.4 years. Two patients (9.5%) required conversion to an open procedure. The median length of postoperative hospitalization was 9 (7-40) days. Overall morbidity was 26.3% and no patients required re-operation. In the UC group, the mean age was 55.2 years. The conversion rate was 14.3% (2/14). The median time to regular diet was 4 (3-10) days and the median length of postoperative hospitalization was 8 (7-25) days. Four patients developed postoperative complications and one patient developed ileostomy retraction requiring urgent operative intervention to rebuild the stoma.

CONCLUSIONS

Laparoscopic surgery in patients with IBD can be accomplished safely and with reasonable operative times, conversion rates and morbidity rates. The main advantages of the laparoscopic approach are rapid recovery, improved cosmesis, less postoperative pain, and patient satisfaction.

Short-term outcomes of laparoscopy combined with enhanced recovery pathway after ileocecal resection for Crohn's disease: a case-matched analysis

BACKGROUND

Laparoscopy combined with an enhanced recovery pathway (ERP) is widely considered to be the first-choice option for patients with colorectal cancer. However, no previous reports have focused on patients with Crohn's disease (CD) treated by laparoscopy and ERP.

METHODS

Twenty patients with CD underwent laparoscopic ileocecal resection with an ERP at two institutions. The ERP protocol included no bowel preparation nor fasting, no nasogastric tube, no abdominal drains, early removal of urinary catheter, early solid dietary intake and mobilization, opioid-sparing analgesia and restrictive fluid management. This group was compared with a matched historical control group of 70 CD patients who underwent laparoscopic ileocecal resection treated with conventional care.

RESULTS

Compliance with the ERP was high (≥80 %) for all items except no drain placement. A significantly earlier return of bowel function (time to first flatus and stool) was observed in the ERP group. Mean postoperative and total length of stay were significantly shorter in the ERP group. Postoperative complications were similar in both groups.

CONCLUSIONS

This is the first reported experience of laparoscopy with ERP in CD patients and suggests that optimized perioperative care combined with minimally invasive techniques may lead to further improvements in surgical outcomes for CD patients.

Minimally invasive approaches for the treatment of inflammatory bowel disease

Despite significant improvements in medical management of inflammatory bowel disease, many of these patients still require surgery at some point in the course of their disease. Their young age and poor general conditions, worsened by the aggressive medical treatments, make minimally invasive approaches particularly enticing to this patient population. However, the typical inflammatory changes that characterize these diseases have hindered wide diffusion of laparoscopy in this setting, currently mostly pursued in high-volume referral centers, despite accumulating evidences in the literature supporting the benefits of minimally invasive surgery. The largest body of evidence currently available for terminal ileal Crohn’s disease shows improved short term outcomes after laparoscopic surgery, with prolonged operative times. For Crohn’s colitis, high quality evidence supporting laparoscopic surgery is lacking. Encouraging preliminary results have been obtained with the adoption of laparoscopic restorative total proctocolectomy for the treatment of ulcerative colitis. A consensus about patients’ selection and the need for staging has not been reached yet. Despite the lack of conclusive evidence, a wave of enthusiasm is pushing towards less invasive strategies, to further minimize surgical trauma, with single incision laparoscopic surgery being the most realistic future development.

Accuracy of imaging for predicting operative approach in Crohn's disease

Background

The aim of this study was to assess the accuracy of preoperative imaging in detecting the extent of disease and predicting the operative approach in patients with Crohn's disease.

Methods

Patients with Crohn's disease who were scheduled to undergo operation were evaluated before operation using computed tomography enteroclysis (CTE) and magnetic resonance enterography (MRE). Preoperative imaging findings were correlated with intraoperative and pathological findings to estimate the capabilities of preoperative imaging in detecting lesions due to Crohn's disease. The operative approach determined before surgery was compared with the procedure actually performed, which was based on intraoperative findings.

Results

Fifty-two patients with Crohn's disease were studied; 26 were evaluated before surgery with CTE and 26 with MRE. Eighty-nine lesions due to Crohn's disease were confirmed surgically (60 small bowel stenoses, 21 fistulas and 8 abscesses). CTE confirmed the presence of 38 of 41 lesions (sensitivity 93 per cent) and MRE 48 of 48 lesions (sensitivity 100 per cent); a correct estimation of the disease with an exact prediction of the operative approach was obtained in 49 (94 per cent) of 52 patients. Discrepant findings between preoperative imaging and operative findings were observed in three patients (6 per cent), who had CTE.

Conclusion

Preoperative imaging using CTE or MRE is highly accurate for assessing Crohn's disease lesions before operation, allowing correct prediction of the operative approach.

A laparoscopic approach reduces short-term complications and length of stay following ileocolic resection in Crohn's disease: an analysis of outcomes from the NSQIP database

AIM

Studies to date examining the impact of laparoscopy in resection for Crohn's disease on short-term morbidity have been limited by small study populations. The aim of this study was to establish the impact of the operative approach (laparoscopic or open) on outcomes after ileocolic resection for Crohn's disease.

METHOD

Ileocolic resections for Crohn's disease were identified using Current Procedural Terminology (CPT) and International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) codes from the National Surgical Quality Improvement Program (NSQIP) database (2005-2009). Complications were categorized as major (organ system damage and systemic sepsis) or minor (incisional and urinary infections). Multivariate 30-day outcomes and length of stay were determined using linear models adjusting for patient characteristics, comorbidities and operative approach.

RESULTS

Of 1917 ileocolic resections, 644 (34%) were performed laparoscopically. At baseline, the open group was significantly older, had more comorbidities, higher American Society of Anesthesiology (ASA) classes, and more intra-operative transfusions (all variables, P<0.05). On multivariate analysis, laparoscopic ileocolic resections were associated with a decrease in major (OR=0.629, 95% CI: 0.430-0.905, P=0.014) and minor (OR=0.576, 95% CI: 0.405-0.804, P=0.002) complications compared with open resections. Laparoscopy was associated with a significant reduction in adjusted length of stay compared with the open approach (-1.08±0.29 days, P=0.0002).

CONCLUSION

After adjusting for comorbidities and perioperative factors, such as preoperative sepsis, higher ASA class and higher transfusion rates in the open group, laparoscopic ileocolic resection for Crohn's disease was found to be a safer choice than the open approach, resulting in fewer complications and length of stay. All other things being equal, such patients should be offered the laparoscopic approach as a first-choice option.

Hospital discharge criteria following colorectal surgery: a systematic review

AIM

The aim of this study was to identify and synthesize the hospital discharge criteria that have been used in the colorectal surgery literature.

METHODS

A systematic literature search was conducted using eight bibliographic databases. Searches were limited to English language journal articles published between January 1996 and October 2009. Primary research applying hospital discharge criteria following colorectal surgery was included. Study selection was made independently by two reviewers. Discharge criteria were extracted from each included study.

RESULTS

The 156 studies identified by the search strategy described 70 different sets of criteria to indicate readiness for discharge. The majority of studies applied a combination of three or four criteria; those most frequently cited were tolerance of oral intake (80%), return of bowel function (70%), adequate pain control (44%) and adequate mobility (35%). End-points employed to determine the achievement of criteria were generally poorly defined.

CONCLUSION

A variety of hospital discharge criteria were applied in the colorectal surgery literature. Development of standardized criteria will allow more accurate comparison of results between studies assessing hospital length of stay or other discharge-related outcome measures.

Laparoscopic surgery for recurrent Crohn's disease

In spite of the recent improvements in drug therapy, surgery still represents the most frequent treatment for Crohn's disease (CD) complications. Laparoscopy has been widely applied over the last twenty years in colorectal surgery and was associated with lower postoperative pain, shorter hospitalization, faster return to daily activities, and better cosmetic results. Laparoscopy experienced a slower diffusion in inflammatory bowel disease surgery than in oncologic colorectal surgery, but proved to be safe and effective, and is currently considered the gold standard for the treatment of primary uncomplicated ileocolic CD. Indications for laparoscopy in CD have recently been widened to embrace more complicated or recurrent CD. This paper reviews the available data on the subset of recurrent CD patients. The reported results indicate that laparoscopy may be safely applied even in selected recurrent CD cases in hands of IBD surgeons with broad laparoscopic experience.

Laparoscopic surgery for recurrent ileocolic Crohn's disease is as safe and effective as primary resection

AIM

The safety and short-term outcome of laparoscopic surgery for recurrent ileocolic Crohn's disease was compared with the outcome following primary resection.

METHOD

Between June 2002 and June 2010, 59 consecutive unselected patients (30 of whom had recurrent disease) underwent laparoscopic ileocolic resection. Four primary resections and one revision were performed as a single incision laparoscopic surgery (SILS) procedure.

RESULTS

There was no difference between the two groups in terms of age, body mass index, American Society of Anesthesiology (ASA) grade or the presence or absence of fistulating disease. The median operating time was significantly longer for the revision group (125 min vs 85 min; P < 0.001). The rate of conversion was 8.5%, morbidity was 20% and mortality was 0% (P = not significant between groups). Risk factors for conversion included a complex fistula, fibrosis and the need to carry out multiple stricturoplasty. Patients in whom surgery was converted had a longer hospital stay and a higher morbidity (40%). The median hospital stay was 3 days, the return to theatre rate was 5% and the re-admission rate was 5% (P = not significant between groups).

CONCLUSION

Laparoscopic surgery for recurrent ileocolic Crohn's disease is safe and can lead to significant short-term benefit, including earlier discharge. Conversion increases the length of stay in hospital and the overall morbidity.

Laparoscopic treatment of Crohn's disease

The surgical and medical management of inflammatory bowel disease (IBD) has significantly evolved over the course of the last two decades. On the medical side, the introduction of biologic therapy has significantly changed the characteristics of the patients undergoing surgery for Crohn's disease (CD), while its impact on the need for surgical intervention and the surgical outcomes of these patients is still debated. On the surgical side, the introduction of and the growing experience with minimally invasive approaches to IBD have had a significant impact on outcomes and quality of life in this patient population. During the past three decades the evidence has been accumulating in favor of a minimally invasive approach to CD. Clearly, this is probably one of the most challenging diseases to treat laparoscopically for the colorectal surgeon, especially when the disease is located in the colon and involves multiple segments.

Video-assisted versus open ileocolic resection in primary Crohn's disease: a comparative case-matched study

Despite the technical difficulties, laparoscopic ileocolic resection for Crohn's disease (CD) has become widely accepted in recent years, due to its potential benefits. There are numerous reports concerning the use of laparoscopy in successfully treating CD, including two randomized trials and few comparative studies. For the most part, these reports outline use of laparoscopic approach in primary distal ileal or ileocolic disease, with a careful selection of the patients. The purpose of this comparative case-control study was to point out potential advantages and disadvantages in short- and long-term outcomes of the laparoscopic approach compared with the open one. From January 1999 to January 2004, 200 patients were admitted in our Surgical Unit for complicated primary CD. 100 patients (group 1) underwent a laparoscopic ileocolic resection, 100 patients (group 2), with alike demographic and clinical characteristics, underwent the same procedure using a traditional approach. The incidence of perforative disease was 32 and 40% in groups 1 and 2, respectively. Average operative time was 140 min (range 90-245 min) in the video-assisted group and 98 min (range 65-255 min) in group 2 (P < 0.05). Postoperative morbidity was 6 and 8% in groups 1 and 2, respectively (P = NS). Recovery of peristalsis occurred within 2-3 days in group 1 and 3-4 days in group 2 (P = NS). Median postoperative hospitalization was 7 days (range 5-18 days) in group 1 and 9 days (range 7-22 days) in control group (P < 0.05). The overall rate of surgical relapse of CD was 8 and 13% in groups 1 and 2, respectively (P = NS), at a mean follow-up of 52 and 60 months, respectively. The 1-year surgical recurrence rate was similar (3%) for the two groups. In conclusions, in spite of the technical difficulties, video-assisted surgery for CD offers advantages over laparotomy, including less postoperative pain, reduced postoperative hospital stay, less disability of the patient, and better cosmetic results. Potential advantages are: easier approach for re-resection, lower rate of postoperative adhesions and bowel obstruction, and lower rate of wound complications.

Crohn's disease: a surgeon's perspective

Crohn's disease (CD) is known for wide anatomic distribution, different presentations, life-threatening complications, and multiple modalities of management. Its multiple implications are still unaddressed. Since all the patients do not show a good response to medical modalities of treatment, a significant percentage of these patients are referred to the surgeon for the palliation of complications or for the ultimate curative treatment. Since most surgeons come across such patients only rarely, it is sometimes difficult for them to choose the appropriate procedure at the time of need. Moreover, the various surgical modalities available for the different presentations and complications of the disease have not been adequately discussed. The aim of this review is to offer insight and a detailed account of the management of CD from a surgical perspective. This review offers an overview of the various surgical options available, their utility in context, and an approach to various scenarios of complicated CD.

Can Laparoscopic Ileocolic Resection be Performed with Comparable Safety to Open Surgery for Regional Enteritis: Data from National Surgical Quality Improvement Program

Laparoscopic ileocolic resection is feasible for Crohn's disease but few studies adjust for the various preoperative, intraoperative, and postoperative variables that may confound comparisons with open surgery. The aim of this study is to compare outcomes after laparoscopic (LICR) and open ileocolic resection (OICR) performed for regional enteritis using National Surgical Quality Improvement Program (NSQIP) data. Retrospective evaluation of data prospectively accrued into the NSQIP database for patients undergoing ileocolic resection for Crohn's by LICR and OICR was performed. LICR (n = 104) and OICR (n = 203) groups had similar age ( P = 0.1), body mass index ( P = 0.9), smoking history ( P = 0.6), steroid use ( P = 0.7), diabetes ( P = 0.3), serum albumin ( P = 0.07), and American Society of Anesthesiologists class ( P = 0.13). LICR group had more female patients ( P = 0.005). Complications including surgical site infections ( P = 0.5), wound dehiscence ( P = 1), pneumonia ( P = 0.1), deep vein thrombosis ( P = 0.3), pulmonary embolism ( P = 1), urinary infection ( P = 0.1), and return to the operating room ( P = 0.2) were similar. LICR had shorter length of hospital stay than OICR ( P < 0.001). In current practice, as observed with the NSQIP data, LICR, performed by experienced surgeons, is comparable in safety to OICR and is associated with a shorter hospital stay.

Minimally invasive colectomy for Crohn's colitis: a single institution experience

BACKGROUND

Minimally invasive surgery for Crohn's ileocolitis is well established but few data exist regarding laparoscopic techniques for Crohn's colitis. We aimed to describe outcomes associated with minimally invasive surgery for Crohn's colitis, including predictors of conversion to laparotomy and postoperative complications.

METHODS

We identified all Crohn's patients who underwent minimal invasive colectomy at our institution from 1997-2008. Data represent frequency (proportion) or median (interquartile range). Multivariate regression identified factors associated with conversion and 30-day complications (odds ratio [95% confidence interval]).

RESULTS

Over 11 years we identified 92 patients, median age 40 (26-51) years, body mass index (BMI) 22.9 (19.3-26.4) kg/m(2); 61% were women. Median Crohn's duration was 6.5 (4-15) years, 11% had prior intestinal resection; medications included immunomodulators (62%), corticosteroids (54%), infliximab (35%). Forty-three cases (47%) were total colectomy, 17 (18%) subtotal colectomy, 32 (35%) were segmental. Straight laparoscopy was used in 57%; 43% were hand-assisted. Median operative time was 248 (190-292) minutes. There were 15 (16%) conversions; only small bowel disease predicted conversion (OR 7 [1.6-35]). Conversion was not associated with increased length of stay or with postoperative complications. Overall postoperative length of stay was 5 (4-7) days. Short-term complications occurred in 34% with reoperation in 5: obstruction n = 3, anastomotic leak n = 2. Only perianal disease predicted complications (2.6 [1.0-6.6]). There was no 30-day mortality.

CONCLUSIONS

Minimally invasive colectomy in patients with Crohn's colitis can be safely accomplished with reasonable operative times, conversion rates, and excellent postoperative outcomes.

Videocirurgia no manejo da doença de Crohn intestinal

A doença de Crohn é uma moléstia com um amplo espectro de manifestações. Seu tratamento é complexo e freqüentemente os pacientes portadores desta afecção necessitam de intervenções cirúrgicas. Com o surgimento da laparoscopia e sua popularização no tratamento das afecções intestinais, demonstrando resultados superiores ao acesso convencional e quebrando paradigmas como sua utilização no tratamento do câncer colorretal, passou-se a cogitar se esse acesso seria indicado também nas doenças inflamatórias intestinais. Ainda hoje, a utilização desta via de acesso na doença de Crohn é tema controverso. Devido à natureza inflamatória desta patologia, o grau de dificuldade cirúrgico está aumentado e muitas dúvidas persistem: há benefício para o paciente? A taxa de conversão não está exageradamente aumentada? É possível indicar esse acesso em casos complicados? Qual o grupo de pacientes que se beneficia da técnica? Nesta revisão apresentamos os dados mais recentes e as evidências científicas que sustentam a indicação da via de acesso laparoscópica no tratamento cirúrgico da doença de Crohn.

Laparoscopic surgery for recurrent ileocolic Crohn's disease

BACKGROUND

Laparoscopic (LAP) surgery is increasingly performed for primary ileocolic Crohn's disease (CD), but its application in patients with recurrent ileocolic CD is less well described. Our aim was to assess whether or not a laparoscopic approach was safe, feasible, and conferred meaningful short-term benefits in this patient population.

METHODS

Patients undergoing LAP surgery for recurrent ileocolic CD at our institution from 1998-2008 were identified using a prospectively maintained database. Potential risk factors for conversion to open surgery and overall patient outcomes were assessed with univariate analysis.

RESULTS

Forty patients were identified, of which 30 (75%) were LAP-completed and 10 (25%) were LAP-converted. The groups did not differ with respect to clinicopathological features. LAP-converted patients were significantly more likely to require adhesiolysis than LAP-completed patients (100% versus 67%, P = 0.04). There was 1 intraoperative complication in a converted patient. LAP-converted patients had longer times to soft diet (4 versus 3 days, P = 0.03) and longer length of stay (7 versus 4 days, P = 0.003). The groups did not differ with respect to incidence of postoperative complications or frequency of readmission within 30 days. There was no mortality.

CONCLUSIONS

In up to 20% of patients with recurrent ileocolic, successful laparoscopic re-resection may be prevented by adhesions. Conversion increased the length of stay without increasing morbidity. We conclude that LAP surgery can be safely performed in selected patients with recurrent ileocolic CD and leads to short-term benefits.

Pre-operative management is associated with low rate of post-operative morbidity in penetrating Crohn's disease

BACKGROUND

Ileocaecal resection for penetrating Crohn's disease is still challenging with a high rate of post-operative morbidity and faecal diversion.

AIM

To report retrospectively the results of pre-operative management for penetrating Crohn's disease focusing on the rate of post-operative major morbidities and need for faecal diversion.

METHODS

Between 1997 and 2007, 78 patients with penetrating Crohn's disease underwent a first ileocaecal resection after a pre-operative management consisting in bowel rest, nutritional therapy, intravenous antibiotics, weaning off steroids and immunosuppressors, and drainage of abscesses when appropriate.

RESULTS

Resection was performed for terminal ileitis associated with (n = 41), abscesses (n = 37) or both (n = 5). A pre-operative nutritional therapy was performed in 50 patients (68%) for 23 days (range, 7-69 days) along with a weaning off steroids and immunosuppressors. A diverting stoma was performed for six patients (7.7%). There was no post-operative death. Post-operative complications were classified as minor in 10 patients (12.8%), and major in four patients (5%). Overall, the post-operative course was uneventful in 58 patients (74%).

CONCLUSION

Pre-operative management for penetrating Crohn's disease allowed ileocaecal resection with low rates of post-operative morbidity and faecal diversion.

A laparoscopic approach to iterative ileocolonic resection for the recurrence of Crohn's disease

BACKGROUND

Laparoscopy is a valuable approach to primary ileocecal resection for ileocolonic Crohn's disease (CD). This study aimed to evaluate the feasibility of using laparoscopy for reoperation in the case of ileocolonic CD recurrence and to determine the risk factors and consequences of conversion for these patients.

METHODS

From 1998 to 2008, 57 patients underwent 62 reoperations for CD recurrence. Of these 62 reoperations, 29 were laparoscopic procedures (laparoscopy group [LG]). Preoperative and intraoperative characteristics and postoperative outcome were compared with those for 33 open procedures (open group [OG]).

RESULTS

The preoperative characteristics were similar in the two groups. The number of intraoperative intestinal injuries was higher in the LG group (n = 5) than in the OG group (n = 0) (p = 0.01). The use of a temporary stoma (7/29 vs. 6/33; nonsignificant difference [NS]) and the mean operating time (215 + or - 70 vs. 226 + or - 107 min, NS) were similar in the two groups. The postoperative mortality was nil in both groups. The overall morbidity rate was 38% (11/29) in LG and 30% (10/33) in OG (NS). Severe complications (DINDO > or = 3) occurred for three of the 29 patients in LG (10%) compared with five of 33 patients in OG (15%) (NS). The median hospital stay was 9 days in both groups. The conversion rate was 31% (9/29). Univariate analysis showed that the risk factors for conversion were fistulizing disease (p = 0.02) and intraoperative intestinal injury (p < 0.001). The morbidity rate was not increased by the need for a conversion (7/20 for the nonconverted vs. 4/9 for the converted patients, NS).

CONCLUSION

Laparoscopy for ileocolonic CD recurrence is challenging and complex. The morbidity rate was similar to that for the open approach, and the risk of small bowel injury associated with laparoscopy could possibly induce postoperative septic complications. However, the authors believe that laparoscopy can be recommended for selected patients with CD recurrence, especially patients with nonfistulizing disease.

Laparoscopy in Crohn's disease

Crohn's disease represents a challenging operative dilemma. The nature of the disease increases the technical complexity of operations, their morbidity, and the likelihood of multiple operations. In this setting, the advantages of laparoscopic surgery, including shorter hospital stays, less adhesion formation, fewer wound complications, and faster recovery of bowel function, are particularly beneficial to the patient. Patients with Crohn's disease requiring operations in the elective and semi-elective setting can all be approached initially laparoscopically. The surgeon's skill set should include extensive experience in advanced laparoscopic bowel surgery as well as open management of Crohn's disease and its complications. Strict adherence to the basic tenet of bowel preservation is imperative. The operations most commonly performed for Crohn's disease include diagnostic laparoscopy, stricturoplasty, small bowel resection, ileocolic resection, colectomy, repair of fistulae, and gastrojejunostomy for bypass of gastric or duodenal disease. Postoperative management includes resumption of steroids, typically without the need for "stress-dosing," bowel rest for a short period, and pain control, which is also less than that experienced with a laparotomy.

Restorative operations for Crohn's disease

Restoration of the continuity of the intestinal tract is one of the key concepts for maintaining the quality of life in patients with Crohn's disease. Restorative procedures have an important role in the scope of operative modalities for these patients. The authors review operative options aimed at fulfilling these goals including restorative partial small bowel resection; segmental, subtotal, and total colectomies; and ileal pouch anal anastomosis in patients with Crohn's disease.

Laparoscopy for inflammatory bowel disease: pushing the envelope

Despite the slower learning curve of laparoscopic colectomy and the lack of prospective randomized trials, laparoscopic procedures have repeatedly demonstrated a shortened length of stay, reduction in postoperative ileus, and earlier resumption of diet. However, laparoscopy in inflammatory bowel disease has unique challenges that must be overcome. For the patient with uncomplicated terminal ileal Crohn's disease, there are definite reproducible advantages to a minimally invasive approach. As surgeons gain experience, more complex cases may be attempted laparoscopically with a low threshold to alternate the approach if difficulties are encountered. We will continue to "push the envelope" in patients with complex Crohn's disease to allow more to be done in complex cases. For the patient with Crohn's colitis and ulcerative colitis, the role of a minimally invasive approach is less well defined. In experienced hands, a laparoscopic total colectomy can be performed safely and offers the patient all the advantages seen with laparoscopic segmental resection. Outcomes are likely to improve with better training, techniques, and equipment. As the field of minimally invasive surgery continues to expand, what is being "pushed" today will be routine in the future.

Surgery for intestinal Crohn's disease recurrence

BACKGROUND

Operative therapy for Crohn's disease (CD) recurrence is supposed to be more complex and demanding than primary resection. The purpose of this study was to assess a postoperative course after reoperation for the recurrence of CD.

METHODS

From 1998 to 2008, 61 patients underwent reoperation for the recurrence of CD. First, risk factors for postoperative morbidity, with special reference to major postoperative complications, were analyzed. Second, a case-matched study was used to compare the postoperative morbidity of 54 ileocolonic resections for the recurrence of CD (reoperation group) with 57 identical primary ileocolonic resections (primary resection group) according to matching criteria (age, fistulizing or stenotic disease, pre-operative steroids therapy, pre-operative general status, and surgical approach).

RESULTS

Postoperative mortality was nil. Postoperative complications were observed in 23 cases (38%). Of these cases, 6 (10%) had major complications (2 anastomotic leakages and 6 intra-abdominal abscesses requiring radiological drainage). Univariate analysis did not identify risk for major complication. None of the 14 patients with temporary stoma developed a major complication (NS). A case-matched study showed a higher morbidity rate (21/54 vs 5/57; P = .0006) with a greater risk of postoperative intra-abdominal abscess (9/59 vs 1/59; P = .007) and a longer postoperative hospital stay in reoperation versus the primary resection group (9 vs 7 days; P < .001).

CONCLUSION

Reoperation for CD recurrence is demanding and complex with a frequent need for an associated surgical procedure (because of the severity of the disease and/or adherences). It also is associated with a higher morbidity rate and a longer hospital stay than primary resection. For these reasons, the indication of temporary defunctionning stoma should be discussed systematically in these patients.

Laparoscopy for benign colorectal diseases

The applicability of laparoscopy to many complex intraabdominal colorectal procedures continues to expand, and has been shown to be feasible and safe in experienced hands. Data are available on the elderly, rectal prolapse, diverticulitis, Hartman's takedown, small bowel obstruction, Crohn's disease, and ulcerative colitis. Clinically relevant advantages have been clearly demonstrated in selected patient populations. Laparoscopic surgery for benign colorectal disease should be considered in patients suitable for this approach to an abdominal operation.

Impact of complex Crohn's disease on the outcome of laparoscopic ileocecal resection: a comparative clinical study in 124 patients

PURPOSE

This prospective study assessed the feasibility of laparoscopic ileocolonic resection for complex Crohn's disease, i.e., recurrence or complication from abscess and/or fistula, and compared postoperative outcomes in patients with and without complex Crohn's disease.

METHODS

Between November 1998 and August 2007, 124 laparoscopic ileocolonic resections were attempted for Crohn's disease: 54 patients with complex Crohn's disease (group I) and 70 patients without complex Crohn's disease (group II). Postoperative mortality and morbidity were compared between group I and group II.

RESULTS

Indications for surgery in group I included fistula (43 percent), abscess (30 percent), and recurrent disease after ileocolonic resection (27 percent). Complex Crohn's disease was significantly associated with increased mean (standard deviations) operative time [214 (13) vs. 191(53) minutes, P < 0.05), increased conversion rate to open procedure (37 percent vs. 14 percent, P < 0.01), and increased use of temporary stoma (39 percent vs. 9 percent, P < 0.001). No patients died. Overall postoperative morbidity was similar between both groups [17 percent vs. 17 percent, P = not significant (NS)], including major surgical postoperative complications (7 percent vs. 6 percent, P = NS). Mean (SD) hospital stay was not statistically different between both groups [8 (3) vs. 7 (3) days, P = NS].

CONCLUSIONS

This large comparative study suggested that laparoscopic ileocolonic resection for complex Crohn's disease was feasible and safe with good postoperative outcomes. In our experience, complex Crohn's disease does not appear as a contraindication to a laparoscopic approach.

Laparoscopic 3-step restorative proctocolectomy: comparative study with open approach in 45 patients

BACKGROUND

To compare the results of a total laparoscopic versus open approach 3-time ileal pouch anal anastomosis (IPAA) for patients with acute or severe colitis complicating inflammatory bowel disease.

METHODS

Consecutive subtotal colectomy was followed by IPAA then by stoma closure. Between 2000 and 2006, 23 consecutive patients, operated through a total laparoscopic approach were well matched with 22 patients operated by open approach.

RESULTS

Overall major complications rate was lower after laparoscopic than after open approach (5/23 vs. 9/22; NS). Mean hospital stay for the 3 consecutive procedures was significantly reduced after laparoscopic versus open approach (27+/-7 d vs. 39+/-27 d; P<0.05).

CONCLUSIONS

Our case-control study suggests that, in experienced centers, a total laparoscopic approach can be viewed as a viable alternative to conventional open 3-step IPAA for the treatment of acute or severe colitis complicating inflammatory bowel disease.

Laparoscopy or conventional open surgery for patients with ileocolonic Crohn's disease? A prospective study

BACKGROUND

Crohn's patients have been considered challenging laparoscopic candidates. The aim of this study was to analyze the short-term and long-term outcomes of laparoscopic and open surgery in consecutive patients with ileocolonic Crohn's disease.

METHODS

Patients were enrolled prospectively but not randomized between August 2002 and October 2006. Patients and disease-specific characteristics, intraoperative variables, and short-term and long-term postoperative outcomes were analyzed.

RESULTS

Overall, 146 consecutive patients were included in the study: 59 in the laparoscopic operation group and 87 in the open operation group. Laparoscopic patients were younger (P = .001), with a lower body mass index (BMI) (P = .008). Operative time was similar between the 2 groups. Blood loss was less in the laparoscopic group (P = .012), and postoperative blood transfusions were administered only to patients in the open group. Narcotic requirement, which was expressed as days on the IV narcotics and as morphine equivalent, was less in the laparoscopic group (P = .01). Duration of stay was less in the laparoscopic group, 5.5 versus 7.0 days, (P = .001). Using step-wise multiple regression analysis, the use of laparoscopic operation was associated with a lesser hospital stay (P < .05). Complication rates were similar, which included 1 anastomotic leak that required reoperation in each group. At a median follow-up of 19 months, there have been no disease recurrences.

CONCLUSIONS

In selected patients, laparoscopy leads to a faster recovery without increasing morbidity and without compromising remission. It should be considered a safe and effective alternative to open operation.

Indications for laparoscopic surgery for Crohn's disease using the Vienna Classification

OBJECTIVE

The aim of this study was to investigate the clinical outcome of laparoscopic surgery for Crohn's disease and clarify the indications using the Vienna Classification.

METHOD

Between September 1994 and July 2004, 107 patients with Crohn's disease underwent 124 procedures. Of these, 91 laparoscopic procedures formed the basis of this study. The Vienna Classification, which consists of three subgroups - age at diagnosis (A1-2), location (L1-4) and behaviour (B1-3) - was applied to compare the conversion to open surgery and incidence of postoperative complications.

RESULTS

Conversion to open surgery was necessary in 12 (13.2%) patients. Major and minor postoperative complications occurred in five (5.5%) and 13 (19.8%) patients respectively. The conversion rate, major and total complications in the B3L3/4 subgroup were significantly greater than in the other subgroups. Multivariate analysis showed that B3L3/4 was the only predictive factor for all complications. However, the incidence of major and all complications in the B3L3/4 subgroup did not differ between the open and laparoscopic surgery groups.

CONCLUSION

Laparoscopic surgery for Crohn's disease is the procedure of choice for all uncomplicated cases (B2L1-4, B3L1/2). For patients in the complicated group (B3L3/4), laparoscopy is also feasible and justified; however, the surgeon must be aware of the propensity for higher rate of conversion.

Laparoscopic surgery for patients with Crohn's colitis: a case-matched study

INTRODUCTION

The purpose of this study was to compare short and long-term outcomes of laparoscopic colectomy with open colectomy in patients with Crohn's disease confined to the colon.

MATERIALS AND METHODS

We reviewed all patients undergoing laparoscopic colectomy for Crohn's disease at our institution between 1994 and 2005. Laparoscopic colectomies were matched to open colectomies by patient age, gender, American Society of Anesthesiologists score, type, and year of surgery. We excluded patients with concomitant small bowel disease.

RESULTS

Twenty-seven laparoscopic cases were matched with 27 open cases. There were seven conversions (26%). There was no mortality. Median operative times were significantly longer after laparoscopic colectomy (240 vs 150 min, P < 0.01), and estimated blood loss was comparable (325 vs 350 ml, P = 0.4). Postoperative complications were similar. Laparoscopic colectomies had shorter median length of stay (5 vs 6 days, P = 0.07) and median time to first bowel movement (3 vs 4 days, P = 0.4). When overall length of stay included 30-day readmissions, the difference in favor of laparoscopy became statistically significant (P = 0.02). Recurrent disease requiring surgery was decreased after laparoscopy, although median follow-up was significantly shorter.

CONCLUSION

Laparoscopic colectomy is a safe and acceptable option for patients with Crohn's colitis. Longer follow-up is needed to accurately establish recurrence rates.

Surgery insight: minimally invasive surgery for IBD

The most frequently described laparoscopic operations for the management of patients with IBD are restorative proctocolectomy for ulcerative colitis and ileocolic resection for Crohn's disease. For patients with Crohn's disease, there is level 1b evidence that, in experienced hands, laparoscopic ileocolic resection enhances recovery and leads to a shorter hospital stay compared with conventional ileocolic resection. The demonstrated advantages of laparoscopic ileocolic resection with regard to cost and cosmesis, and the acceptable long-term results achieved (which are at least comparable to those achieved by conventional ileocolic resection) favor the use of laparoscopic ileocolic resection over conventional ileocolic resection in patients with ileocolic Crohn's disease. For patients with ulcerative colitis, the expected advantages of laparoscopic restorative proctocolectomy over conventional restorative proctocolectomy have yet to be clearly shown. Although there is a trend towards a reduced hospital stay (of only 1.6 days) when laparoscopic restorative proctocolectomy is performed, operating times are disproportionably prolonged. The most important argument for offering patients with IBD the chance to undergo a laparoscopic procedure, rather than conventional open surgery, is (particularly for women) the long-term superior cosmesis and body image it confers.

Body image, cosmesis, quality of life, and functional outcome of hand-assisted laparoscopic versus open restorative proctocolectomy: long-term results of a randomized trial

BACKGROUND

This study aimed to compare quality of life (QOL), functional outcome, body image, and cosmesis after hand-assisted laparoscopic (LRP) versus open restorative proctocolectomy (ORP). The potential long-term advantages of LRP over ORP remain to be determined. The most likely advantage of LRP is the superior cosmetic result. It is, however, unclear whether the size and location of incisions affect body image and QOL.

METHODS

In a previously conducted randomized trial comparing LRP with ORP, 60 patients were prospectively evaluated. The primary end points were body image and cosmesis. The secondary end points were morbidity, QOL, and functional outcome. A body image questionnaire was used to evaluate body image and cosmesis. The Short Form-36 Health Survey and the Gastrointestinal Quality of Life Inventory were used to assess QOL. Body image and QOL also were assessed preoperatively.

RESULTS

A total of 53 patients completed the QOL and functional outcome questionnaires. There were no differences in functional outcome, morbidity, or QOL between LRP and ORP. At a median of 2.7 years after surgery, 46 patients returned the questionnaires regarding body image, cosmesis, and morbidity. The body image and cosmesis scores of female patients were significantly higher in the LRP group than in the ORP group (body image, 17.4 vs 14.9; cosmesis, 19.1 vs 13.0, respectively). The female patients in the ORP group had significantly lower body image scores than the male patients (14.9 vs 18.3).

CONCLUSIONS

This study is the first to show that ORP has a negative impact on body image and cosmesis as compared with LRP. Functional outcome, QOL, and morbidity are similar for the two approaches. The advantages of a long-lasting improved body image and cosmesis for this relatively young patient population may compensate for the longer operating times and higher costs, particularly for women.
