Laparoscopic versus open bowel resection for Crohn's disease

Surgical management of pediatric Crohn's disease

Management of pediatric-onset Crohn's disease uniquely necessitates consideration of growth, pubertal development, psychosocial function and an increased risk for multiple future surgical interventions. Both medical and surgical management are rapidly advancing; therefore, it is increasingly important to define the role of surgery and the breadth of surgical options available for this complex patient population. Particularly, the introduction of biologics has altered the disease course; however, the ultimate need for surgical intervention has remained unchanged. This review defines and evaluates the surgical techniques available for management of the most common phenotypes of pediatric-onset Crohn's disease as well as identifies critical perioperative considerations for optimizing post-surgical outcomes.

Surgical features to reduce anastomotic recurrence of Crohn's disease that requires reoperation: a systematic review

Anastomotic recurrence after intestinal resection is one of the main embarrassing problems encountered during Crohn's disease (CD) management. This complication is often associated with an expected consequence, mainly a multiple intestinal resection. This systematic review evaluates published evidence on surgical features to reduce surgical recurrence after bowel resection and provide surgeons with recommendations based on published evidence. We conducted bibliographic research on September 05, 2020, through PubMed, Cochrane database, and Google scholar. We retained meta-analysis, randomized clinical trials, and controlled clinical trials. The strength of clinical data and subsequent recommendations were graded according to the Oxford Centre for Evidence-Based Medicine. Fourteen articles were retained. Early resection reduces surgical relapse and the need for additional medical treatment. There was no difference between conventional and laparoscopic bowel resection. Mesenteric excision seems to reduce surgical recurrence. Stapled side-to-side anastomosis reduces surgical recurrence. However, no difference was observed between Kono-S anastomosis ensure at least similar anastomotic recurrence rate compared to conventional anastomosis. Surgical recurrence was reduced after bowel resection when compared to stricturoplasty. There was no difference between the one and two steps resection. Several surgical features have been investigated. Some of them were unanimously found to be effective in lengthening the disease-free relapse. However, others are still controversial.

Impact of surgery on quality of life in Crohn's disease: short- and mid-term follow-up

Active Crohn's disease has a substantial impact on Quality of Life (QoL). Medical management could be associated to side effects, hospitalization, long treatment period and requires patient's compliance, impacting QoL. Ileocecal resection (ICR) is often required, open or laparoscopic. Aim of the study was to assess Health-Related (HR) QoL changes following ICR, and to identify factors impacting on QoL in the short and mid-term. From a single institution, we created a prospective database of patients undergoing ICR from 01/2009 to 12/2015. HRQoL was analysed with Cleveland Global Quality of Life (CGQL) score, Overall Quality of Happiness (OQH), and asking patients if they would have surgery again. QoL scores were recorded at 30 days, 6, 12 and 36 months postoperatively and compared according to follow-up timing, technique, medical treatment and demographics. Statistical analysis included 187 patients. Mean follow-up was 3.8 ± 2.9 years. Both at 30 days and 6 months postoperatively, CGQL, its items and OQH increased significantly (p < 0.001). Increased values were also recorded at 1 and 3 years; 88% of patients would undergo surgery again. Laparoscopy was associated with improved CGQL scores, while preoperative steroids with worsen data. Young female patients, with penetrating pattern, experienced greater HRQoL improvements. Surgery is associated with improvements of HRQoL and patients' happiness in the short and mid-term. Laparoscopy, steroid-free and young patients showed the best results. ICR should be considered a reasonable alternative to non-operative strategies in selected cases.

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.

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.

Postoperative recurrent luminal Crohn's disease: a systematic review

Despite improved immunosuppressive therapy, surgical resection is still often required for uncontrolled inflammatory disease and the stenosing and perforating complications of Crohn's disease. However, surgery is not curative. A majority of patients develop disease recurrence at or above the anastomosis. Subclinical endoscopically identifiable recurrence precedes the development of clinical symptoms; identification and treatment of early mucosal recurrence may therefore prevent clinical recurrence. Therapy to achieve mucosal healing should now be the focus of postoperative therapy. A number of clinical risk factors for the development of earlier postoperative recurrence have been identified, and reasonable evidence is now available regarding the efficacy of drug therapies in preventing recurrence. This evidence now needs to be incorporated into prospective treatment strategies.

Surgical management of Crohn's disease

INTRODUCTION

Crohn's disease is an inflammatory bowel disease that can affect the entire gastrointestinal tract. It is chronic and incurable, and the mainstay of therapy is medical management with surgical intervention as complications arise. Surgery is required in approximately 70% of patients with Crohn's disease. Because repeat interventions are often needed, these patients may benefit from bowel-sparing techniques and minimally invasive approaches. Various bowel-sparing techniques, including strictureplasty, can be applied to reduce the risk of short-bowel syndrome.

METHODS

A review of the available literature using the PubMed search engine was undertaken to compile data on the surgical treatment of Crohn's disease.

RESULTS AND CONCLUSION

Data support the use of laparoscopy in treating Crohn's disease, although the potential technical challenges in these settings mandate appropriate prerequisite surgical expertise.

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.

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.

Small bowel emergency surgery: literature's review

Emergency surgery of the small bowel represents a challenge for the surgeon, in the third millennium as well. There is a wide number of pathologies which involve the small bowel. The present review, by analyzing the recent and past literature, resumes the more commons. The aim of the present review is to provide the main indications to face the principal pathologies an emergency surgeon has to face with during his daily activity.

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.

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.

Advances in surgical approaches to Crohn's disease: minimally invasive surgery and biologic therapy

In the last 5 years, significant advances have been made in the surgical approaches to, and medical management of, Crohn's disease (CD). This review summarizes these advances as they relate to the care of surgical patients with CD, with an emphasis on innovations in surgical techniques, specifically minimally invasive (laparoscopic) surgery, as well as on recent developments in biologic pharmacotherapies for CD that have important clinical implications for surgical patients. These include recent insights gained into the role of biologic therapy with infliximab and other newer agents in preoperative and postoperative therapy of CD patients. We will also review other recent developments relevant to the current and future surgical care of CD patients, including the treatment of less common forms of CD, such as duodenal and colonic CD, and the role of novel strategies such as fibrin glue, fistula plugs and stem cell therapy for the treatment of fistulizing anorectal CD.

National trends and outcomes for the surgical therapy of ileocolonic Crohn's disease: a population-based analysis of laparoscopic vs. open approaches

PURPOSE

The laparoscopic approach to Crohn's disease has demonstrated benefits in several small series. We sought to examine its use and outcomes on a national level.

METHODS

All admissions with a diagnosis of Crohn's disease requiring bowel resection were selected from the 2000-2004 Nationwide Inpatient Sample. Regression analyses were used to compare outcome measures and identify independent predictors of undergoing laparoscopy.

RESULTS

Of 396,911 patients admitted for Crohn's disease, 49,609 (12%) required surgical treatment. They were predominately Caucasian (64%), female (54%), and with ileocolic disease (72%). Most had private insurance (71%) and had surgery in urban hospitals (91%). Laparoscopic resection was performed in 2,826 cases (6%) and was associated with lower complications (8% vs. 16%), shorter length of stay (6 vs. 9 days), lower charges ($27,575 vs. $38,713), and mortality (0.2% vs. 0.9%, all P < 0.01). Open surgery was used more often for fistulas (8% vs. 1%) and when ostomies were required (12% vs. 7%). Independent predictors of laparoscopic resection were age <35 [odds ratio (OR) = 2.4], female gender (OR = 1.4), admission to a teaching hospital (OR = 1.2), ileocecal location (OR = 1.5), and lower disease stage (OR = 1.1, all P < 0.05). Ethnic category, insurance status, and type of admission (elective vs. non-elective) were not associated with operative method (P > 0.05).

CONCLUSIONS

A variety of patient- and system-related factors influence the utilization of laparoscopy in Crohn's disease. Laparoscopic resection is associated with excellent short-term outcomes compared to open surgery.

Laparoscopic resection for Crohn's disease: an experience with 335 cases

BACKGROUND

Laparoscopic resection for Crohn's disease has had a slow adoption rate in gastrointestinal surgery. This is not unexpected considering the inflammatory nature of the disease, the need for reoperative surgery, and the presence of fistulas. The authors review their experience with 335 laparoscopic resections for Crohn's disease over the past 15 years.

METHODS

This study is a retrospective analysis of a prospective database from one surgeon at the Mount Sinai Hospital, New York, NY.

RESULTS

Since 1993, 335 patients with Crohn's disease in the current series have undergone laparoscopic resection. The mean age of the patients was 39 years, and 54% of the patients were women. In most cases, the indication for surgery was intestinal obstruction (73%) or abdominal pain (16%). The most common operation was primary ileocolic resection, performed for 178 cases (49%). Secondary ileocolic resections were performed for 20% and small bowel resections for 11% of the cases. Of the 117 patients with enteric fistulas, 45% had multiple fistulas. There were 80 enteroenteric, 51 ileosigmoid, 33 enteroabdominal wall, and 22 ileovesical fistulas. Multiple resections were performed for 33 patients (9%). Eight conversions occurred (2%), primarily because of large inflammatory masses involving the intestinal mesentery. The mean length of hospital stay was 5 days, and the mean operative time was 177 min (range, 62-400 min). There were no mortalities. The complications were primarily bowel obstruction, anastamotic leak, and postoperative bleeding, resulting in a postoperative complication rate of 13%.

CONCLUSION

This review summarizes the largest series of laparoscopic resection for Crohn's disease to date. The most common operation performed was ileocolic resection. Fistulous disease is common, but it is not a contraindication to laparoscopic resection. These cases can be managed safely and with acceptable morbidity in experienced hands.

Postoperative Crohn’s disease recurrence: A practical approach

Crohn's disease is a chronic inflammatory condition that may involve any segment of the gastrointestinal tract. Although several drugs have proven efficacy in inducing and maintaining disease in remission, resectional surgery remains as a cornerstone in the management of the disease, mainly for the treatment of its stenosing and penetrating complications. However, the occurrence of new mucosal (endoscopic) lesions in the neoterminal ileum early after surgery is almost constant, it is followed in the mid-term by clinical symptoms and, in a proportion of patients, repeated intestinal resections are required. Pathogenesis of postoperative recurrence (POR) is not fully understood, but luminal factors (commensal microbes, dietary antigens) seem to play an important role, and environmental and genetic factors may also have a relevant influence. Many studies tried to identify clinical predictors for POR with heterogeneous results, and only smoking has repeatedly been associated with a higher risk of POR. Ileocolonoscopy remains as the gold standard for the assessment of appearance and severity of POR, although the real usefulness of the available endoscopic score needs to be revisited and alternative techniques are emerging. Several drugs have been evaluated to prevent POR with limited success. Smoking cessation seems to be one of the more beneficial therapeutic measures. Aminosalicylates have only proved to be of marginal benefit, and they are only used in low-risk patients. Nitroimidazolic antibiotics, although efficient, are associated with a high rate of intolerance and might induce irreversible side effects when used for a long-term. Thiopurines are not widely used after ileocecal resection, maybe because some concerns in giving immunomodulators in asymptomatic patients still remain. In the era of biological agents and genetic testing, a well-established preventive strategy for POR is still lacking, and larger studies to identify good clinical, serological, and genetic predictors of early POR as well as more effective drugs (or drug combinations) are needed.

Long-term surgical recurrence, morbidity, quality of life, and body image of laparoscopic-assisted vs. open ileocolic resection for Crohn's disease: a comparative study

PURPOSE

Several studies have compared conventional open ileocolic resection with a laparoscopic-assisted approach. However, long-term outcome after laparoscopic-assisted ileocolic resection remains to be determined. This study was designed to compare long-term results of surgical recurrence, quality of life, body image, and cosmesis in patients who underwent laparoscopic-assisted or open ileocolic resection for Crohn's disease.

METHODS

Seventy-eight consecutive patients who underwent ileocolic resection during the period 1995 to 1998 were analyzed; 48 underwent a conventional open approach in the Academic Medical Centre (Amsterdam, The Netherlands) and 30 underwent a laparoscopic-assisted approach in the Leiden University Medical Centre (Leiden, The Netherlands). Primary outcome parameters were reoperation and readmission rate. Secondary outcome parameters were quality of life, body image, and cosmesis.

RESULTS

The two groups were comparable for characteristics of sex, age, and immunosuppressive therapy. Seventy-one patients had a complete follow-up of median 8.5 years. Resection for recurrent Crohn's disease was performed in 6 of 27 (22 percent) and 10 of 44 (23 percent) patients in the laparoscopic and open groups, respectively. Reoperations for incisional hernia were only performed after conventional open ileocolic resection (3/44 = 6.8 percent). Quality of life and body image were comparable, but cosmesis scores were significantly higher in the laparoscopic group.

CONCLUSIONS

Despite small numbers, we found that surgical recurrence and quality of life after laparoscopic-assisted and open ileocolic resection were comparable. Incisional hernias occurred only after open ileocolic resection, and laparoscopic-assisted ileocolic resection resulted in a significantly better cosmesis.

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.

Laparoscopic surgery for Crohn's disease: a meta-analysis

PURPOSE

This study was designed to determine the safety and feasibility of laparoscopic surgery in Crohn's disease.

METHODS

A search of published studies in English between January 1990 and February 2006 was performed by using the MEDLINE and PubMed databases and the Cochrane Central Register of Controlled Trials. The studies were reviewed by two independent assessors. Meta-analysis with the Forest plot was performed when raw data, means, and standard deviations were available.

RESULTS

The rate of conversion from laparoscopic to open surgery was 11.2 percent. Laparoscopic procedures took longer to perform compared with open procedures, with a weighted mean difference of 25.54 minutes (P = 0.03). Patients who underwent laparoscopic surgery had a more rapid recovery of bowel function, with a weighted mean difference of 0.75 days (P = 0.02) and were able to tolerate oral intake earlier, with a weighted mean difference of 1.43 days (P = 0.0008). The duration of hospitalization was shorter, with a weighted mean difference of 1.82 days (P = 0.02). Morbidity was lower for laparoscopic procedures compared with open procedures (odds ratio, 0.57; 95 percent confidence interval, 0.37-0.87; P = 0.01). The rate of disease recurrence was similar for both laparoscopic and open surgery.

CONCLUSIONS

Laparoscopic surgery for Crohn's disease takes longer to perform, but there are significant short-term benefits to the patient. The morbidity also is lower, and the rate of disease recurrence is similar. Therefore, laparoscopic surgery for Crohn's disease is both safe and feasible.

Comparison of laparoscopic and open ileocecal resection for Crohn's disease: a metaanalysis

BACKGROUND

The role of laparoscopic surgery for patients with ileocecal Crohn's disease is a contentious issue. This metaanalysis aimed to compare open resection with laparoscopically assisted resection for ileocecal Crohn's disease.

METHODS

A literature search of the Medline, Ovid, Embase, and Cochrane databases was performed to identify comparative studies reporting outcomes for both laparoscopic and open ileocecal resection. Metaanalytical techniques were applied to identify differences in outcomes between the two groups. Sensitivity analysis was undertaken to evaluate the heterogeneity of the study.

RESULTS

Of 20 studies identified by literature review, 15 satisfied the criteria for inclusion in the study. These included outcomes for 783 patients, 338 (43.2%) of whom had undergone laparoscopic resection, with an overall conversion rate to open surgery of 6.8%. The operative time was significantly longer in the laparoscopic group, by 29.6 min (p = 0.002), although the blood loss and complications in the two groups were similar. In terms of postoperative recovery, the laparoscopic patients had a significantly shorter time for recovery of their enteric function and a shorter hospital stay, by 2.7 days (p < 0.001).

CONCLUSIONS

For selected patients with noncomplicated ileocecal Crohn's disease, laparoscopic resection offered substantial advantages in terms of more rapid resolution of postoperative ileus and shortened hospital stay. There was no increase in complications, as compared with open surgery. The contraindications to laparoscopic approaches for Crohn's disease remain undefined.

Factors that predict conversion in 69 consecutive patients undergoing laparoscopic ileocecal resection for Crohn's disease: a prospective study

PURPOSE

This prospective study was designed to identify factors that could predict conversion in patients undergoing first laparoscopic ileocecal resection for Crohn's disease.

METHODS

Between 1998 and 2004, 69 consecutive patients (32 males; mean age, 32 +/- 9 years) who had undergone a first laparoscopic ileocecal resection for Crohn's disease were included in a prospective study. Twenty-one patients (30 percent) were converted into laparotomy. Possible factors for conversion were analyzed by both univariate and multivariate analyses.

RESULTS

No patient died. Four patients (9 percent; 2 in each group) required five reoperations because of intraperitoneal hemorrhage (n = 1), anastomotic fistula (n = 3), and small-bowel obstruction (n = 1). Mean hospital stay was significantly increased in converted compared with laparoscopic patients (9 +/- 4 vs. 7 +/- 3 days; P < 0.05). On univariate analysis, more than three episodes of acute flare of Crohn's disease (P = 0.02), male gender (P = 0.03), preoperative immunosuppressive drugs (P = 0.04), intra-abdominal abscess or fistula at the time of laparoscopy (P = 0.02), and resection of other intestinal segment (P = 0.02) were factors that predicted conversion. On multivariate analysis, recurrent medical episodes of Crohn's disease (odds ratio, 2; 95 percent confidence interval, 1-4), and intra-abdominal abscess or fistula at the time of laparoscopy (odds ratio, 15; 95 percent confidence interval, 4-78) were the two independent risk factors for conversion.

CONCLUSIONS

This prospective study demonstrated that the severity of the disease increased significantly the conversion rate of the first laparoscopic ileocecal resection. Knowledge of these risk factors for conversion could be helpful in preoperative preparation and counseling of patients.

Metaanalysis of trials comparing laparoscopic and open surgery for Crohn's disease

BACKGROUND

Several studies in the literature have suggested that laparoscopic surgery for Crohn's disease is associated with faster postoperative recovery and a morbidity and recurrence rate similar to that for open surgery. Most of these studies have been limited by a small sample size and a short follow-up period.

METHODS

To clarify whether open or laparoscopic resection results in a better outcome, a metaanalysis of studies was performed comparing the two procedures for Crohn's disease. Pooled effects were estimated using a random-effects model.

RESULTS

Laparoscopic surgery required more operative time than open surgery (26.8 min; 95% confidence interval [CI], 6.4-47.2 min), but resulted in a shorter duration of ileus and a decreased hospital stay (-2.62 days; 95% CI, -3.62 to -1.62). Laparoscopic surgery also was associated with a decreased rate for postoperative bowel obstruction and surgical recurrences.

CONCLUSIONS

Laparoscopic surgery for Crohn's disease is feasible, safe, and associated with shorter duration of ileus and a shorter hospital stay.

Assessment of long-term quality of life after laparoscopic and open surgery for Crohn's disease

OBJECTIVE

Surgery for Crohn's disease (CD) is associated with a high recurrence rate and quality of life (QOL) in these patients is controversial. The aim of this study was to assess QOL in patients after laparoscopic and open surgery for CD by two different validated instruments, a generic nonspecific score and a specific gastrointestinal QOL index.

PATIENTS AND METHODS

Patients with CD who underwent elective laparoscopic or open ileocaecal resection with primary anastomosis between 1992 and 2000 were followed for recurrence and surgery-related complications. QOL was assessed by the SF-36 Health Survey containing a mental (MCS) and a physical (PCS) component summary score and by the Gastrointestinal Quality of Life Index (GIQLI) developed by Eypasch.

RESULTS

Thirty-seven patients with a mean age of 48.8 +/- 18.4 years including 23 females and 14 males were evaluated at a mean follow-up of 42.6 +/-25.8 months (minimum of 8 months). Twenty-one (57%) patients underwent laparoscopic resection and 16 (43%) open surgery. Both groups were well matched for age, gender, ASA class and body mass index. Fourteen (38%) patients developed recurrent disease and 3 (8%) had postoperative incisional hernias. Overall, QOL scores were 103 +/- 26.8 for the GIQLI, 47.2 +/- 11.8 for the PCS, and 49.2 +/- 11.5 for the MCS. The GIQLI correlated well with the SF36, correlation coefficient = 0.68 for GIQLI vs PCS (95% CI, 0.41,0.95) and 0.67 for GIQLI vs MCS (95%CI, 0.39, 0.95), respectively. When compared to the general US population, mean GIQLI scores (-13.8, P = 0.002) and mean PCS scores (-4.7, P = 0.001) were significantly lower in these patients than in healthy individuals. In a multivariate analysis of impact factors on QOL, recurrence within the follow-up period was the single significant determinant reducing the PCS (-35.1, P = 0.026) and the GIQLI (-36.1, P = 0.018).

CONCLUSION

QOL is significantly reduced in patients with CD at long-term follow-up after both laparoscopic and open surgery. Recurrence is the only factor adversely affecting QOL of CD patients in remission irrespective of the operative technique applied.

Laparoscopic versus open ileocolic resection for Crohn's disease

OBJECTIVE

Laparoscopic ileocolic (LI) resection for Crohn's disease has several potential advantages over the traditional open technique. The objective of this study was to compare early surgical outcomes in patients having laparoscopic versus open ileocolic resections for Crohn's disease.

METHODS

Data collected prospectively from 21 patients having LI resection for Crohn's disease between 1995 and 2001 were compared to data from 19 patients having open ileocolic resection for Crohn's disease between 1990 and 1995.

RESULTS

Patients in both groups had similar ages, sex distribution, and rates of previous abdominal surgery. Mean operating time was not significantly different between the groups. There was a nonsignificant trend to less postoperative analgesic requirement in the laparoscopic group. Resumption of liquid (P <.001) and solid (P =.01) diet, return of bowel function [flatus (P =.008), feces (P =.008)] and time to discharge (P =.001) all occurred significantly more quickly in the laparoscopic group. There was no difference in the rates of morbidity between the two groups.

CONCLUSIONS

LI resection for Crohn's disease appears to be safe and has comparable if not superior results to open surgery in the short term.

Laparoscopic surgery for inflammatory bowel disease

Laparoscopic surgery for inflammatory bowel disease is an expanding field, which has physical benefits to the patient and economic benefits to the trust and community.

Laparoscopic-assisted bowel resection offers advantages over open surgery for treatment of segmental Crohn's disease in children

BACKGROUND/PURPOSE

Minimally invasive approaches have been shown to decrease hospital length of stay (LOS), decrease postoperative pain, and speed return to normal activity for a number of intraabdominal procedures. In this study, laparoscopic (LAP)-assisted bowel resection is compared with an open technique for patients undergoing an initial bowel resection.

METHODS

A retrospective review was conducted of 28 patients (12 LAP, 16 open) undergoing initial bowel resection for segmental Crohn's disease.

RESULTS

Patients in the LAP group had decrease LOS (5.5 days v 11.5 days) decreased days of parenteral narcotics (3 days v 5 days) and more rapid return to regular diet (3 days v 5 days).

CONCLUSIONS

The data suggest that the laparoscopic approach may offer advantages to pediatric patients undergoing an initial bowel resection for segmental Crohn's disease.

Total intracorporeal laparoscopic resection of Crohn's disease

BACKGROUND/PURPOSE

The benefits of laparoscopic resection for Crohn's disease have been well established in the adult literature. This modality more recently has been applied to children. The authors report their experience in this age group.

METHODS

A prospective series of all pediatric Crohn's patients treated laparoscopically in one surgical practice was studied for demographic data, operative details, and outcome.

RESULTS

Fifteen patients with diagnosis of Crohn's disease, ages 9 to 17 years, underwent laparoscopic ileocolic resection between February of 1998 and 2002. Patients' weights ranged from 42 to 80 kg. All patients had fixed strictures involving the terminal ileum and ileocecal valve and had failed medical therapy. A 4-port approach (one 12-mm and 3 5-mm) was utilized in all cases. Resection and anastomosis was performed intracorporeally, and the specimen was retrieved through the 12-mm port site. The average operating time was 110 minutes (range, 90 to 180 minutes). Oral feedings were started after 24 hours of nasogastric suction. Hospital stay averaged 4 days (range, 3 to 8 days). One patient had a fever on postoperative day 3. Contrast study showed a small anastomotic leak with no associated collection, and the patient responded to conservative management. One other patient whose pathologic diagnosis questioned the initial Crohn's diagnosis presented with an anastomotic stricture and underwent redo resection laparoscopically with good outcome. No other complications were noted, and all patients were symptom free at follow-up.

CONCLUSIONS

Laparoscopic resection of Crohn's disease in children is safe and effective.

Laparoscopic segmental intestinal resection

There are numerous disease processes in the pediatric population that require segmental intestinal resection with primary anastomosis. These include intestinal strictures from necrotizing enterocolitis in neonates, resection of congenital lesions such as a Meckel's diverticulum or intestinal webs, and strictures from inflammatory bowel disease. Whereas the treatment of these lesions previously required a major laparotomy, they now can be approached using a minimally invasive surgical (MIS) approach. Techniques from laparoscopic intestinal mobilization with extracorporeal resection and anastomosis to complete intracorporeal resection and anastomosis have been successfully developed for pediatric patients. The benefits are similar to those achieved from other laparoscopic procedures and include decreased postoperative pain and morbidity, reduced postoperative hospitalization and faster return to normal activity. Early experience suggests that the minimally invasive approach is acceptable and, perhaps, favorable in the treatment of segmental intestinal disease in infants and children.

Surgical treatment of inflammatory bowel disease

Appropriate surgical management of Crohn disease is predicated on multiple variables, but stricturoplasty is generally reserved for small bowel disease, whereas resection is utilized in ileocolonic inflammation and favored for large bowel disease. Laparoscopic resection is becoming increasingly useful and justified for ileocolic resections, and segmental resection should be strongly considered for limited large bowel inflammation. Some centers are also using a laparoscopic approach for the surgical treatment of acute or chronic ulcerative colitis, although the benefits are less apparent. Proctocolectomy with ileostomy or ileal pouch-anal anastomosis returns the patient's quality of life to a level comparable to that enjoyed by the general population. Creation of a pouch is performed in most instances, but early complications may warrant pouch revision and later complications, such as pouchitis, can mandate pouch excision.

Review article: indication and type of surgery in Crohn's disease

The large majority of patients affected by Crohn's disease require surgery during their clinical history. Radical resection originally advocated for Crohn's disease does not decrease the recurrence rate, and repeated resections predispose patients to the development of short-bowel syndrome. Over the last few years, conservative surgery has become accepted by many authors as a safe means of treating obstructive Crohn's disease. In this review article we analyse the efficacy and safety of conservative techniques, in comparison with resective surgery. Indications, advantages and technical aspects of resective and conservative surgery are reported. The experience with 489 patients treated for complicated or treatment refractory Crohn's disease in our Institution suggests that strictureplasty is a safe and effective procedure in many cases, as reported by other authors. The risk of cancer in areas of active disease as in stenosis treated with strictureplasty seems to be negligible. Resective surgery still represents the 'gold standard' in patients with perforating Crohn's disease; however, conservative surgery, usually contraindicated in perforating Crohn's disease, can be advocated in patients with localized perforating disease presenting an actual risk of short bowel syndrome.

Surgery of the small intestine

The small intestine is the portal of entry of virtually all nutrients and is also the site of diverse inflammatory and neoplastic diseases. This field has recently attracted intense excitement as a result of novel clinical and experimental techniques, combined modality therapies, and basic science applications. This review will highlight important clinical advances in surgery for Crohn disease, short bowel syndrome, transplantation, trauma, and polyposis. Promising experimental approaches, novel methods of clinical assessment, and multimodality treatment will also be considered.
