A systematic review and meta-analysis of laparoscopic vs open restorative proctocolectomy

Surgical trend including minimally invasive surgeries for ulcerative colitis in the COSUC study: the largest multicenter cohort study in Japan

BACKGROUND

The number of patients with ulcerative colitis (UC) is increasing rapidly in Asia. No large study has evaluated the clinical outcomes of hand-sewn ileal pouch-anal anastomosis (IPAA). This study aimed to create a large database of the surgical outcomes of UC, present the trends of surgical procedures, and evaluate the impact of minimally invasive procedures on UC.

METHODS

Data of patients first treated from 2005 to 2019 were collected; two-staged surgery data were extracted, and minimally invasive surgery (MIS) and open surgery (OS) outcomes were compared using propensity-score matching.

RESULTS

The data of 1558 cases were selected as the main analysis set. The number of surgical cases of UC has been increasing, with increasing proportion of MIS cases (2005: 43%, 2019: 84%). The median age of the patients increased in these 15 years (39.5-56 years old). Of 873 patients who underwent two-staged surgery, after 3:1 matching, 408 MIS and 176 OS cases were compared. Hand-sewn anastomoses were performed in 293 MIS (72.0%) and 142 OS-IPAA (80.7%) cases. The proportion of early complications (≥ Grade 3) did not vary between the two groups. Intraoperative blood loss was lower and blood transfusions were less frequent in the MIS group.

CONCLUSIONS

The proportion of MIS for UC has rapidly increased over the past 15 years. The total number of MIS and OS complications did not vary significantly between the groups. The short-term advantages of MIS include reduced blood loss and less necessity for blood transfusions.

Colorectal cancer in ulcerative colitis after liver transplantation for primary sclerosing cholangitis: a systematic review and pooled analysis of oncological outcomes

INTRODUCTION

Patients with ulcerative colitis (UC) receiving liver transplantation (LT) due to primary sclerosing cholangitis (PSC) have higher risk of developing colorectal cancers (CRC). Aim of this systematic review was to define the patients' features, immunosuppressive management, and oncological outcomes of LT recipients with UC-PSC developing CRC.

METHODS

Searches were conducted in PubMed (MEDLINE), Cochrane Library, Web of Science for all English articles published until September 2023. Inclusion criteria were original articles including patients specifying outcomes of interest. Primary endpoints comprised incidence of CRC, disease free survival (DFS), overall survival (OS) and cancer recurrence. Secondary endpoints were patient's and tumor characteristics, graft function, immunosuppressive management and PSC recurrence. PROSPERO CRD42022369190.

RESULTS

Fifteen studies included, 88 patients were identified. Patients (mean age: 50 years) had a long history of UC (20 years), mainly with active colitis (79%), and developed tumor within the first 3 years from LT, while receiving a double or triple immunosuppressive therapy. Cumulative incidence of tumor was 5.5%. At one, two and three years, DFS was 92%, 82% and 75%, while OS was 87%, 81% and 79% respectively. Disease progression rate was 15%. After CRC surgery, 94% of patients maintained a good graft functionality, with no reported cases of PSC recurrence.

CONCLUSIONS

After LT, patients with PSC and UC have an increased risk of CRC, especially in presence of long history of UC and active colitis. Surgical resection guarantees satisfactory mid-term oncological outcomes, but samples are limited, and long-term data are lacking. National and international registry are auspicial to evaluate long-term oncological outcomes and to optimize clinical management.

Usefulness of Hand-assisted Laparoscopic Restorative Proctocolectomy for Ulcerative Colitis in the Era of Laparoscopic Surgery - A Single-center Observational Study

Objectives

Hand-assisted laparoscopic surgery (HALS) combines the benefits of laparoscopic surgery with the tactile feedback from open surgery. In the current era of laparoscopic surgery, the significance of HALS as a technical transition has diminished. This study clarified the usefulness of HALS in restorative proctocolectomy (RPC) for ulcerative colitis (UC) in the era of laparoscopic surgery.

Methods

The 212 patients who underwent RPC with ileal pouch-anal anastomosis between 2007 and 2023 were included in this study. The patients were divided into three groups, open surgery (OS), HALS, and conventional laparoscopic surgery (LAP), and their characteristics, surgical outcomes, surgical complications, and functional outcomes were compared.

Results

The number of surgical techniques was OS in 21 cases, HALS in 184 cases, and LAP in 7 cases. The number of surgeons was two for OS and HALS, and four for LAP, with OS and HALS having fewer surgeons than LAP. The length of the skin incision was 13, 7, and 3 cm for OS, HALS, and LAP, respectively, and the operation times was 250, 286, and 576 minutes for OS, HALS, and LAP, respectively, with LAP having the longest operation time. The postoperative complications and function did not differ markedly among the three groups.

Conclusions

In RPC for UC, HALS involved fewer surgeons and a shorter operative time than LAP. Even in the era of laparoscopic surgery, HALS remains a useful option, especially when a shorter operation time is required or when the number of available surgeons is insufficient.

Transanal ileal pouch-anal anastomosis: A systematic review and meta-analysis of technical approaches and clinical outcomes

PURPOSE

Transanal minimally invasive surgery has theoretical advantages for ileal pouch-anal anastomosis surgery. We performed a systematic review assessing technical approaches to transanal IPAA (Ta-IPAA) and meta-analysis comparing outcomes to transabdominal (abd-IPAA) approaches.

METHODS

Three databases were searched for articles investigating Ta-IPAA outcomes. Primary outcome was anastomotic leak rate. Secondary outcomes included conversion rate, post operative morbidity, and length of stay (LoS). Staging, plane of dissection, anastomosis, extraction site, operative time, and functional outcomes were also assessed.

RESULTS

Searches identified 13 studies with 404 unique Ta-IPAA and 563 abd-IPAA patients. Anastomotic leak rates were 6.3% and 8.4% (RD 0, 95% CI -0.066 to 0.065, p = 0.989) and conversion rates 2.5% and 12.5% (RD -0.106, 95% CI -0.155 to -0.057, p = 0.104) for Ta-IPAA and abd-IPAA. Average LoS was one day shorter (MD -1, 95% CI -1.876 to 0.302, p = 0.007). A three-stage approach was most common (47.6%), operative time was 261(± 60) mins, and total mesorectal excision and close rectal dissection were equally used (49.5% vs 50.5%). Functional outcomes were similar. Lack of randomised control trials, case-matched series, and significant study heterogeneity limited analysis, resulting in low to very low certainty of evidence.

CONCLUSIONS

Analysis demonstrated the feasibility and safety of Ta-IPAA with reduced LoS, trend towards less conversions, and comparable anastomotic leak rates and post operative morbidity. Though results are encouraging, they need to be interpreted with heterogeneity and selection bias in mind. Robust randomised clinical trials are warranted to adequately compare ta-IPAA to transabdominal approaches.

Ileal pouch-anal anastomosis provides good functional and quality of life outcomes following proctocolectomy: A 33-year single centre experience

BACKGROUND

Restorative proctocolectomy (RP) with ileal pouch-anal anastomosis (IPAA) remains the gold standard for the surgical management of patients with medically refractive mucosal ulcerative colitis. We aimed to identify functional and quality of life (QOL) outcomes in RP and IPAA surgery patients at our institution.

METHODS

A retrospective observational study was performed including all patients who had undergone RP and IPAA between August 1984 and November 2017 at Royal Prince Alfred Hospital (RPAH).

RESULTS

316 consecutive patients were identified, median age 39 (range 5 to 81) years. The median duration of disease was 60 (range 1 to 528) months. Ulcerative colitis was the main preoperative diagnosis with the main RP indication being failure of medical treatment. The median postoperative stay post-IPAA was 11 (range of 5 to 67) days. Pouchitis was the most common late complication (22.1%), bleeding pouch (3.5%) the earliest, with a 6.8% rate of symptomatic anastomotic leak. Visual analogue scale QOL measure (P-value <0.001), St Marks incontinence score (P-value = 0.001) and Cleveland clinic score (P-value = 0.002) all revealed significant improvement in functional outcomes and QOL.

CONCLUSION

QOL and functional outcomes following RP with IPAA in patients at our institution are excellent and comparable to institutions with larger patient numbers.

Short-term outcomes in robotic vs laparoscopic ileal pouch-anal anastomosis surgery: a propensity score match study

PURPOSE

Laparoscopic ileal pouch-anal anastomosis (IPAA) surgery offers improved short-term outcomes over open surgery but can be technically challenging. Robotic surgery has been increasingly used for IPAA surgery, but there is limited evidence supporting its use. This study aims to compare the short-term outcomes of laparoscopic and robotic IPAA procedures.

METHODS

All consecutive patients receiving laparoscopic and robotic IPAA surgery at 3 centres, from 3 countries, between 2008 and 2019 were identified from prospectively collated databases. Robotic surgery patients were propensity score matched with laparoscopic patients for gender, previous abdominal surgery, ASA grade (I, II vs III, IV) and procedure performed (proctocolectomy vs completion proctectomy). Their short-term outcomes were examined.

RESULTS

A total of 89 patients were identified (73 laparoscopic, 16 robotic). The 16 patients that received robotic surgery were matched with 15 laparoscopic patients. Baseline characteristics were similar between the two groups. There were no statistically significant differences in any of the investigated short-term outcomes. Length of stay trend was higher for laparoscopic surgery (9 vs 7 days, p = 0.072) CONCLUSION: Robotic IPAA surgery is safe and feasible and offers similar short-term outcomes to laparoscopic surgery. Length of stay may be lower for robotic IPAA surgery, but further larger scale studies are required in order to demonstrate this.

Minimally Invasive and Robotic Surgery for Ulcerative Colitis

Significant advancements have been made over the last 30 years in the use of minimally invasive techniques for curative and restorative operations in patients with ulcerative colitis (UC). Numerous studies have demonstrated the safety and feasibility of laparoscopic and robotic approaches to subtotal colectomy (including in the urgent setting), total proctocolectomy, completion proctectomy, and pelvic pouch creation. Data show equivalent or improved short-term postoperative outcomes with minimally invasive techniques compared to open surgery, and equivalent or improved long-term bowel function, sexual function, and fertility. Overall, while minimally invasive techniques are safe and feasible for properly selected UC patients, surgeons must remember to abide by the principles of high-quality proctectomy and pouch creation and convert to open if necessary.

Equivalency of short-term perioperative outcomes after open, laparoscopic and robotic ileal anal pouch anastomosis. Does procedure complexity override operative approach?

Background

Ileal pouch anal anastomosis is the treatment of choice for patients with chronic ulcerative colitis and familial adenomatous polyposis undergoing a proctocolectomy and desiring bowel continuity. It is a technically complex operation associated with significant morbidity and may be performed by an open, laparoscopic, or robotic approach. However, there is a paucity of data regarding the comparative perioperative outcomes between these 3 techniques outside of institutional studies.

Methods

The NSQIP targeted proctectomy data set was used to identify patients who underwent open, laparoscopic, and robotic ileal pouch anal anastomosis between 2016 and 2019. Thirty-day outcomes between different surgical approaches were compared using univariate and multivariable analysis.

Results

During the study period, 1,067 open, 971 laparoscopic, and 341 robotic ileal pouch anal anastomosis were performed. The most frequent indications were inflammatory bowel disease (64%), malignancy (18%), and familial adenomatous polyposis (7%). Mean age of the cohort was 43 ± 15 years with 43% female and 76% with body mass index ≤ 30 kg/m². Overall morbidity was 26.8% for the entire cohort with 4% anastomotic leak, 6% reoperation, 21% ileus, and 21% readmission rate. After adjusting for available confounders, operative approach was not associated with better short-term outcomes, including length of stay, overall morbidity, anastomotic leak, reoperation, incidence of ileus, and 30-day readmissions.

Conclusion

Ileal pouch anal anastomosis continues to be associated with significant postoperative morbidity regardless of operative approach. Patient-related advantages in terms of perioperative outcomes for laparoscopic and robotic platforms compared to open surgery are less pronounced in complex operations such as ileal pouch anal anastomosis.

•

Ileal anal pouch anastomosis is a technically complex operation associated with significant postoperative 30-day morbidity.

•

Postoperative morbidity is similar between open, laparoscopic, and robotic approaches.

•

In complex operations such as ileal anal pouch anastomosis, the short-term perioperative advantages of minimally invasive approaches may not be clinically evident.

It probably worked: a Bayesian approach to evaluating the introduction of activity-based hospital payment in Israel

Background

In 2013–2014, Israel accelerated adoption of activity-based payments to hospitals. While the effects of such payments on patient length of stay (LoS) have been examined in several countries, there have been few analyses of incentive effects in the Israeli context of capped reimbursements and stretched resources.

Methods

We examined administrative data from the Israel Ministry of Health for 14 procedures from 2005 to 2016 in all not-for-profit hospitals (97% of the acute care beds). Survival analyses using a Weibull distribution allowed us to examine the non-negative and right-skewed data. We opted for a Bayesian approach to estimate relative change in LoS.

Results

LoS declined in 7 of 14 procedures analyzed, notably, in 6 out of 7 urological procedures. In these procedures, reduction in LoS ranged between 11% and 20%. The estimation results for the control variables are mixed and do not indicate a clear pattern of association with LoS.

Conclusions

The decrease in LoS freed resources to treat other patients, which may have resulted in reduced waiting times. It may have been more feasible to reduce LoS for urological procedures since these had relatively long LoS. Policymakers should pay attention to the effects of decreases in LoS on quality of care. Stretched hospital resources, capped reimbursements, retrospective subsidies and underpriced procedures may have limited hospitals' ability to reduce LoS for other procedures where no decrease occurred (e.g., general surgery).

Anastomotic Leak after Ileal Pouch-Anal Anastomosis

There are special considerations when treating anastomotic leak after restorative proctocolectomy and ileal pouch-anal anastomosis. The epidemiology, risk factors, anatomic considerations, diagnosis and management, as well as the short- and long-term consequences to the patient are unique to this patent population. Additionally, there are specific concerns such as "tip of the J" leaks, transanal management of anastomotic leak/presacral sinus, functional outcomes after leak, and considerations of redo pouch procedures.

State-of-the-art surgery for ulcerative colitis

Ulcerative colitis (UC) is an autoimmune-mediated colitis which can present in varying degrees of severity and increases the individual’s risk of developing colon cancer. While first-line treatment for UC is medical management, surgical treatment may be necessary in up to 25–30% of patients. With an increasing armamentarium of biologic therapies, patients are presenting for surgery much later in their course, and careful understanding of the complex interplay of the disease, its management, and the patient’s overall health is necessary when considering he appropriate way in which to address their disease surgically. Surgery is generally a total proctocolectomy either with pelvic pouch reconstruction or permanent ileostomy; however, this may need to be spread across multiple procedures given the complexity of the surgery weighed against the overall state of the patient’s health. Minimally invasive surgery, employing either laparoscopic, robotic, or transanal laparoscopic approaches, is currently the preferred approach in the elective setting. There is also some emerging evidence that appendectomy may delay the progression of UC in some individuals. Those who treat these patients surgically must also be familiar with the numerous potential pitfalls of surgical intervention and have plans in place for managing problems such as pouchitis, cuffitis, and anastomotic complications.

Robotic versus laparoscopic ileal pouch-anal anastomosis (IPAA): a systematic review and meta-analysis

BACKGROUND

Restorative proctocolectomy with ileal-pouch anal anastomosis (IPAA) is a curative and cancer preventative procedure in patients with ulcerative colitis (UC) and familial adenomatous polyposis (FAP). It can be technically difficult laparoscopically, and hence the robotic platform has been suggested as a way to enable minimally invasive surgery in more patients. This systematic review examines robotic proctectomy or proctocolectomy with IPAA. A limited meta-analysis was performed on data comparing the robotic approach to laparoscopy.

METHODS

We searched MEDLINE, EMBASE and the Cochrane database for case series of robotic IPAA procedures and studies comparing the robotic to laparoscopic or open procedures. Data examined includes operating time, conversion to open, length of stay, complications, blood loss, return of bowel function, reoperation rate and functional outcomes.

RESULTS

Five non-randomised studies compared robotic to laparoscopic techniques; one compared robotic to open surgery and three case series are included. Operating time was significantly longer in robotic cases. Estimated blood loss was significantly less in three of four studies which reported this; hospital stay was significantly less in two. There were nonsignificant reductions in complications and readmission rates. Pooled analysis of four papers with adequate data showed a nonstatistically significant trend to less complications in robotic procedures. Three studies assessed functional and quality of life outcomes, with little difference between the platforms.

CONCLUSIONS

Available data suggests that the robotic platform is safe to use for IPAA procedures. There is minimal evidence for clinical advantages, but with little data to base decisions and significant potential for improvements in technique and cost-effectiveness, further use of the platform for this operation is warranted. It is vital that this occurs within an evaluation framework.

Subtotal colectomy in ulcerative colitis—long term considerations for the rectal stump

BACKGROUND

The initial operation of choice in many patients presenting as an emergency with ulcerative colitis is a subtotal colectomy with end ileostomy. A percentage of patients do not proceed to completion proctectomy with ileal pouch anal anastomosis.

AIM

To review the existing literature in relation to the significant long-term complic-ations associated with the rectal stump, to provide an overview of options for the surgical management of remnant rectum and anal canal and to form a consolidated guideline on endoscopic screening recommendations in this cohort.

METHODS

A systematic review was carried out in accordance with PRISMA guidelines for papers containing recommendations for endoscopy surveillance in rectal remnants in ulcerative colitis. A secondary narrative review was carried out exploring the medical and surgical management options for the retained rectum.

RESULTS

For rectal stump surveillance guidelines, 20% recommended an interval of 6 mo to a year, 50% recommended yearly surveillance 10% recommended 2 yearly surveillance and the remaining 30% recommended risk stratification of patients and different screening intervals based on this. All studies agreed surveillance should be carried out via endoscopy and biopsy. Increased vigilance is needed in endoscopy in these patients. Literature review revealed a number of options for surgical management of the remnant rectum.

CONCLUSION

The retained rectal stump needs to be surveyed endoscopically according to risk stratification. Great care must be taken to avoid rectal perforation and pelvic sepsis at time of endoscopy. If completion proctectomy is indicated the authors favour removal of the anal canal using an intersphincteric dissection technique.

[Minimally invasive and robot-assisted surgery for chronic inflammatory bowel disease : Current status and evidence situation]

The majority of cases of inflammatory bowel disease (IBD) can be treated by minimally invasive surgery. The advantages of standard laparoscopic approaches compared to open surgery with respect to short-term and long-term outcome parameters have been adequately proven with evidence level 1 for ileocecal resection in Crohn's disease. For many other indications there are at least several larger registry or case-control studies that have shown advantages for laparoscopy. For robot-assisted surgery the feasibility has principally been demonstrated for IBD, whereby at least for ulcerative colitis limited data suggest comparable results to the standard laparoscopic approach. Single port approaches have so far not been able to demonstrate any relevant advantages in IBD surgery. Major advantages for transanal minimally invasive surgery (TAMIS) for performing restorative proctocolectomy could not be demonstrated in two larger case-controlled studies but it was at least shown to be a comparable alternative to standard laparoscopy. Overall, it seems unlikely that the recently described new laparoscopic approaches will result in measurable advantages for the patient in comparison to standard laparoscopy as the access trauma is not significantly changed. In general, the indications to perform minimally invasive surgery must always be based on the basic principles of IBD surgery and contraindications have to be considered in individual cases as the advantages of laparoscopic approaches are levelled out in the long run.

Surgery and paediatric inflammatory bowel disease

The incidence of paediatric Crohn's disease (CD) and ulcerative colitis (UC) is increasing. Surgical intervention is required during childhood in approximately 25% of children diagnosed with CD, and for 10% of those diagnosed with UC. Although there is evidence that the rate of surgical intervention undertaken in children is decreasing since the introduction of biologic therapy, this may only represent a delay rather than true reversal of the risk of surgery. Surgery for CD is not curative and limited resection is the key principle thus preserving bowel length. For UC, subtotal colectomy is relatively curative; ileo-anal pouch anastomosis can be performed to restore bowel continuity.

Ileal-anal pouches: A review of its history, indications, and complications

The ileal pouch anal anastomosis (IPAA) has revolutionised the surgical management of ulcerative colitis (UC) and familial adenomatous polyposis (FAP). Despite refinement in surgical technique(s) and patient selection, IPAA can be associated with significant morbidity. As the IPAA celebrated its 40^th anniversary in 2018, this review provides a timely outline of its history, indications, and complications. IPAA has undergone significant modification since 1978. For both UC and FAP, IPAA surgery aims to definitively cure disease and prevent malignant degeneration, while providing adequate continence and avoiding a permanent stoma. The majority of patients experience long-term success, but “early” and “late” complications are recognised. Pelvic sepsis is a common early complication with far-reaching consequences of long-term pouch dysfunction, but prompt intervention (either radiological or surgical) reduces the risk of pouch failure. Even in the absence of sepsis, pouch dysfunction is a long-term complication that may have a myriad of causes. Pouchitis is a common cause that remains incompletely understood and difficult to manage at times. 10% of patients succumb to the diagnosis of pouch failure, which is traditionally associated with the need for pouch excision. This review provides a timely outline of the history, indications, and complications associated with IPAA. Patient selection remains key, and contraindications exist for this surgery. A structured management plan is vital to the successful management of complications following pouch surgery.

Abnormal Pouchogram Predicts Pouch Failure Even in Asymptomatic Patients

BACKGROUND

Anastomotic complications after restorative total proctocolectomy with IPAA for ulcerative colitis alter functional outcomes and quality of life and may lead to pouch failure. Routine contrast enema of the pouch assesses anastomotic integrity before ileostomy reversal, but its clinical use is challenged.

OBJECTIVE

The purpose of this research was to assess the relationship among preoperative clinical characteristics, abnormal pouchography, and long-term pouch complications.

DESIGN

This was a retrospective chart review.

SETTINGS

The study was conducted at a tertiary care center between 2000 and 2010.

PATIENTS

Ulcerative colitis patients with IPAA undergoing pouchography before ileostomy closure were included.

MAIN OUTCOME MEASURES

Patient demographics, incidence of pouch-related complications, and findings on pouchogram were recorded. Primary outcome was pouch failure, defined as excision or permanent diversion of the ileoanal pouch. Independent predictors of pouch failure were determined by multivariate regression.

RESULTS

A total of 262 patients with ulcerative colitis were included. Contrast extravasation was seen in 27 patients (10.3%): 14 (51.9%) were clinically asymptomatic at the time of pouchogram. Six (22.2%) of 27 patients with extravasation developed pouch failure despite normalization of the pouchogram before ileostomy closure. Forty patients (15.3%) were found to have pouch-anal anastomotic stenosis; only 1 developed pouch failure. Pre-IPAA serum albumin and hemoglobin levels were inversely associated with contrast extravasation (serum albumin: OR = 0.42; hemoglobin: OR = 0.77; p < 0.05). Contrast extravasation was associated with delayed takedown operation (average = 67 d), increased risk (OR = 5.25; p < 0.01), and shorter time (median = 32.0 vs 72.5 mo; HR = 5.88; p < 0.05) to pouch failure, as well as increased risk of pouch-related complications (p < 0.05).

LIMITATIONS

The study was limited by its retrospective nature and small number of patients who developed pouch failure.

CONCLUSIONS

Pouchography before ileostomy takedown is useful in identifying patients with ulcerative colitis at risk for postoperative complications. Radiologic resolution of IPAA-related leak does not reliably predict healing; caution is warranted in this subgroup. See Video Abstract at http://links.lww.com/DCR/A818.

The Association of Coloproctology of Great Britain and Ireland consensus guidelines in surgery for inflammatory bowel disease

AIM

There is a requirement of an expansive and up to date review of surgical management of inflammatory bowel disease (IBD) that can dovetail with the medical guidelines produced by the British Society of Gastroenterology.

METHODS

Surgeons who are members of the ACPGBI with a recognised interest in IBD were invited to contribute various sections of the guidelines. They were directed to produce a procedure based document using literature searches that were systematic, comprehensible, transparent and reproducible. Levels of evidence were graded. An editorial board was convened to ensure consistency of style, presentation and quality. Each author was asked to provide a set of recommendations which were evidence based and unambiguous. These recommendations were submitted to the whole guideline group and scored. They were then refined and submitted to a second vote. Only those that achieved >80% consensus at level 5 (strongly agree) or level 4 (agree) after 2 votes were included in the guidelines.

RESULTS

All aspects of surgical care for IBD have been included along with 157 recommendations for management.

CONCLUSION

These guidelines provide an up to date and evidence based summary of the current surgical knowledge in the management of IBD and will serve as a useful practical text for clinicians performing this type of surgery.

Review of current practice and outcomes following ileoanal pouch surgery: lessons learned from the Ileoanal Pouch Registry and the 2017 Ileoanal Pouch Report

AIM

The second Association of Coloproctology of Great Britain and Ireland (ACPGBI) Ileoanal Pouch Registry (IPR) report was released in July 2017 following a first report in 2012. This article provides a summary of data derived from the most recent IPR report (2017 Ileoanal Pouch Report. https://www.acpgbi.org.uk/content/uploads/2016/07/Ileoanal-Pouch-Report-2017-FINAL.compressed.pdf).

METHOD

The IPR is an electronic database of voluntarily submitted data including patient demographics, disease, intra-operative and postoperative factors submitted by consultant surgeons or delegates. Data up to 31 March 2017 have been analysed for this report.

RESULTS

A total of 5352 pouch operations were carried out at 76 UK and four European centres by 154 surgeons over four decades. Recorded procedures have increased over time but data submission is voluntary and underestimates actual volume. Significant variation exists in institutional volume; 73 centres entered data on patients undergoing pouch surgery during the past 5 years. Of these, 44 centres have submitted ≤ 10 cases, with 10 centres submitting one patient and nine centres two cases. Since 2013, minimal access surgery has been employed in 54% of cases. Rectal dissection was undertaken in the total mesorectal excision plane in 69%. J-pouch configuration was used in 99% of cases and 90% of pouch-anal anastomoses were performed using a stapled technique. Including all years, the IPR rate of pelvic sepsis was 9.4% and the rate of pouch failure was 4.7%.

CONCLUSION

The IPR holds the largest voluntary repository of data on ileoanal pouch surgery. The second report from the IPR records marked refinements in surgical technique over time but also highlights wide variation in institutional caseload and outcome across the UK.

Post-operative morbidity and mortality of a cohort of steroid refractory acute severe ulcerative colitis: Nationwide multicenter study of the GETECCU ENEIDA Registry

BACKGROUND

Despite the increased use of rescue medical therapies for steroid refractory acute severe ulcerative colitis, mortality related to this entity still remains high. We aimed to assess the mortality and morbidity related to colectomy and their predictive factors in steroid refractory acute severe ulcerative colitis, and to evaluate the changes in mortality rates, complications, indications of colectomy, and the use of rescue therapy over time.

METHODS

We performed a multicenter observational study of patients with steroid refractory acute severe ulcerative colitis requiring colectomy, admitted to 23 Spanish hospitals included in the ENEIDA registry (GETECCU) from 1989 to 2014. Independent predictive factors of mortality were assessed by binary logistic regression analysis. Mortality along the study was calculated using the age-standardized rate.

RESULTS

During the study period, 429 patients underwent colectomy, presenting an overall mortality rate of 6.3% (range, 0-30%). The main causes of death were infections and post-operative complications. Independent predictive factors of mortality were: age ≥50 years (OR 23.34; 95% CI: 6.46-84.311; p < 0.0001), undergoing surgery in a secondary care hospital (OR 3.07; 95% CI: 1.01-9.35; p = 0.047), and in an emergency setting (OR 10.47; 95% CI: 1.26-86.55; p = 0.029). Neither the use of rescue medical treatment nor the type of surgical technique used (laparoscopy vs. open laparotomy) influenced mortality. The proportion of patients undergoing surgery in an emergency setting decreased over time (p < 0.0001), whereas the use of rescue medical therapy prior to colectomy progressively increased (p > 0.001).

CONCLUSIONS

The mortality rate related to colectomy in steroid refractory acute severe ulcerative colitis varies greatly among hospitals, reinforcing the need for a continuous audit to achieve quality standards. The increasing use of rescue therapy is not associated with a worse outcome and may contribute to reducing emergency surgical interventions and improve outcomes.

Perioperative outcomes and adverse events of robotic colorectal resections for inflammatory bowel disease: a systematic literature review

The purpose of this study was to assess outcome measures and cost-effectiveness of robotic colorectal resections in adult patients with inflammatory bowel disease. The Cochrane Library, PubMed/Medline and Embase databases were reviewed, using the text "robotic(s)" AND ("inflammatory bowel disease" OR "Crohn's" OR "Ulcerative Colitis"). Two investigators screened abstracts for eligibility. All English language full-text articles were reviewed for specified outcomes. Data were presented in a summarised and aggregate form, since the lack of higher-level evidence studies precluded meta-analysis. Primary outcomes included mortality and postoperative complications. Secondary outcomes included readmission rate, length of stay, conversion rate, procedure time, estimated blood loss and functional outcome. The tertiary outcome was cost-effectiveness. Eight studies (3 case-matched observational studies, 4 case series and 1 case report) met the inclusion criteria. There was no reported mortality. Overall, complications occurred in 81 patients (54%) including 30 (20%) Clavien-Dindo III-IV complications. Mean length of stay was 8.6 days. Eleven cases (7.3%) were converted to open. The mean robotic operating time was 99 min out of a mean total operating time of 298.6 min. Thirty-two patients (24.7%) were readmitted. Functional outcomes were comparable among robotic, laparoscopic and open approaches. Case-matched observational studies comparing robotic to laparoscopic surgery revealed a significantly longer procedure time; however, conversion, complication, length of stay and readmission rates were similar. The case-matched observational study comparing robotic to open surgery also revealed a longer procedure time and a higher readmission rate; postoperative complication rates and length of stay were similar. No studies compared cost-effectiveness between robotic and traditional approaches. Although robotic resections for inflammatory bowel disease are technically feasible, outcomes must be interpreted with caution due to low-quality studies.

Surgery in ulcerative colitis: When? How?

Ulcerative Colitis (UC) is an idiopathic chronically-remitting inflammatory bowel disorder characterized by a contiguous inflammation of the colonic mucosa affecting the rectum that generally extends proximally in a continuous manner through the entire colon. Patients typically experience intermittent exacerbations, with symptoms characterized by bloody diarrhea associated with urgency and tenesmus. The anatomical extent of mucosal involvement is the most important factor determining disease course and is an important predictor of colectomy. The precise etiology of UC is unknown. However, a combination of genetic predisposition and environmental factors seems to have a key role in the development of the disease. UC usually is mildly active but it can be a life-threatening condition because of colonic and systemic complications, and later in the disease course due to the development of colorectal cancer. Interestingly, even if pathogenetic features detected in patients with sporadic CRC can be also found in UC-related colorectal cancer (UC-CRC), this latter is, usually, driven by an inflammation-driven pathway rising from a non-neoplastic inflammatory epithelium to dysplasia to cancer. Thus, a long-term follow-up with colonoscopy surveillance has been recommended. Approximately 15% of UC patients develop an acute attack of severe colitis, and 30% of these patients require colectomy. The initial treatment strategy in UC typically follows the traditional step-up approach. One third of the patients will not respond to steroid therapy and cyclosporine and infliximab are the most common salvage agents employed in these cases in order to avoid emergent surgery. Unfortunately, although a significant short-term benefit have been observed after infliximab treatment, the colectomy rate have remained stable. Surgery in UC depends on the stage of the disease as well as patient's status and is divided into the following settings: urgent, emergent and elective. Despite many efforts the surgical management of UC remains a significant challenge. A multidisciplinary management of UC is key in order to define the best timing and the best procedure for each patient in an individualized basis.

Laparoscopic Versus Open Restorative Proctocolectomy for Familial Adenomatous Polyposis

PURPOSE

This study compared outcomes after laparoscopic (LAP) or conventional (open) total proctocolectomy with outcomes after ileal J-pouch anal anastomosis (IPAA) at a single institution.

METHODS

Charts from 133 familial adenomatous polyposis patients (1997-2013) were reviewed. Demographic data (age, sex, color, American Society of Anesthesiologists [ASA] status, previous surgery, and body mass index) and surgical outcomes (length of stay, early and late morbidity, reoperation, and mortality rates) were compared among 63 patients undergoing IPAA.

RESULTS

Demographic features were similar among patients (25 open and 38 LAP). Conversely, colorectal cancer at diagnosis prevailed in the open group (60% versus 31.6%; P = .02). Tumor stages (P = .65) and previous surgery index (20% versus 10.5%; P = .46) were similar. Surgical length was longer for LAP (374 versus 281 minutes, P = .003). Short-term complication rates (28% versus 28.9%), hospital stay (10.9 versus 8.9 days), and total long-term reoperations (28% versus 21%) were not statistically different. However, major late morbidity (16% versus 2.6%; P < .001) and late reoperation rates (16% versus 5.2%; P < .05) were greater among open patients. Both groups did not differ regarding pouch failure rates (8% versus 5.2%). There was no operative mortality in the present series.

CONCLUSIONS

(1) LAP IPAA is a safe procedure associated with a low conversion rate, (2) short-term results showed no clear advantages for both approaches, and (3) a greater risk of major late complications and late reoperations should be expected after open procedures.

溃疡性结肠炎的外科微创治疗

外科治疗是溃疡性结肠炎(ulcerative colitis, UC)的重要组成部分, 全结直肠切除、回肠贮袋肛管吻合术(ileal pouch-anal anastomosis, IPAA)已成为标准术式. 近年来在微创外科技术的迅猛发展与普及下, 越来越多医疗中心开展腹腔镜IPAA手术. 腹腔镜IPAA手术相比于开腹手术的在术后近、远期疗效中的优势逐渐突显, 且其安全有效性已达成共识. 目前更多更为微创的技术也陆续尝试应用于IPAA手术. 但是由于UC患者自身疾病的特点和IPAA术式的复杂性, 腹腔镜IPAA手术仍未达到标准化、规范化水平. 本文主要针对UC微创外科术后疗效和合理应用的研究进展作一述评.

[Laparoscopic proctocolectomy technique : Restorative proctocolectomy with ileal pouch-anal anastomosis in ulcerative colitis. Video article]

Laparoscopic restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) constitutes a curative treatment option for therapy-refractory ulcerative colitis. A two-stage procedure with loop ileostomy at the time of IPAA is the most frequent variant of surgery. The aim of the procedure is the complete removal of the colon and rectum with simultaneous restoration of gastrointestinal continuity and preservation of continence functions. Long-term quality of life following laparoscopic proctocolectomy with IPAA is good and comparable with a healthy reference population. The surgical technique is demonstrated in detail with the help of a video of the operation, which is available online.

[The technique of restorative proctocolectomy with ileal J‑pouch : Standards and controversies]

BACKGROUND

Restorative proctocolectomy (RPC) is the standard of care in the case of medically refractory disease and in neoplasia in ulcerative colitis (UC).

OBJECTIVES

This review aims at providing an overview of the current evidence on standards, innovations, and controversies with regard to the surgical technique of RPC.

RESULTS

RPC is the standard of care in the surgical management of UC refractory to medical treatment and in neoplasia. Due to its simplicity and good functional outcomes, the J‑pouch is the most used pouch design. RPC is usually performed as a two-stage procedure. In the presence of risk factors, a three-stage procedure should be performed. The technically more demanding mucosectomy and hand sewn anastomosis does not seem to result in a better oncologic outcome than stapled anastomosis. Functional results appear marginally better after stapled anastomosis, but the rectal cuff should not exceed 2 cm in this reconstruction. The laparoscopic approach is at least as good as the open approach. For the new, innovative surgical approaches such as robotics and transanal surgery, only feasibility but no advantages have yet been demonstrated.

CONCLUSION

The evidence in regard to controversial points remains limited.

Restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis: A narrative review

Restorative proctocolectomy with ileal pouch-anal anastomosis (RP-IPAA) is the gold standard surgical treatment for ulcerative colitis. However, despite the widespread use of RP-IPAA, many aspects of this treatment still remain controversial, such as the approach (open or laparoscopic), number of stages in the surgery, type of pouch, and construction type (hand-sewn or stapled ileal pouch-anal anastomosis). The present narrative review aims to discuss current evidence on the short-, mid-, and long-term results of each of these technical alternatives as well as their benefits and disadvantages. A review of the MEDLINE, EMBASE, and Ovid databases was performed to identify studies published through March 2016. Few large, randomized, controlled studies have been conducted, which limits the conclusions that can be drawn regarding controversial issues. The available data from retrospective studies suggest that laparoscopic surgery has no clear advantages compared with open surgery and that one-stage RP-IPAA may be indicated in selected cases. Regarding 2- and 3-stage RP-IPAA, patients who underwent these surgeries differed significantly with respect to clinical and laboratory variables, making any comparisons extremely difficult. The long-term results regarding the pouch type show that the W- and J-reservoirs do not differ significantly, although the J pouch is generally preferred by surgeons. Hand-sewn and stapled ileal pouch-anal anastomoses have their own advantages, and there is no clear benefit of one technique over the other.

Systemic Acute-phase Response in Laparoscopic and Open Ileal Pouch Anal Anastomosis in Patients With Ulcerative Colitis: A Case-matched Comparative Study

AIM

The current trial was designed to study and compare the postoperative outcomes and systemic acute responses between patients undergoing laparoscopic-ileal pouch anal anastomosis (LAP-IPAA) and open IPAA for ulcerative colitis.

METHODS

The clinical records of patients who underwent 89 restorative proctocolectomy procedures with IPAA were reviewed. After determining which patients underwent LAP-IPAA versus open IPAA, an equivalent number of controls matched for age and ulcerative colitis severity were selected.

RESULTS

Twenty of 22 patients who underwent laparoscopic surgery met the inclusion criteria. Patients who underwent LAP-IPAA had significantly shorter times to first walking (P=0.021) and food intake (P=0.0003). The LAP-IPAA group had significantly lower interleukin-6 and interleukin-1ra levels soon after surgery (P=0.011 and P=0.0076). The LAP-IPAA group had significantly lower C-reactive protein levels on postoperative day 1 (P=0.0027).

CONCLUSIONS

LAP-IPAA is a less-invasive operative procedure than open IPAA with respect to the postoperative systemic inflammatory response and postoperative recovery.

Laparoscopic restorative proctocolectomy with ileal pouch-anal anastomosis for Peutz-Jeghers syndrome with synchronous rectal cancer

We report on a patient diagnosed with Peutz-Jeghers syndrome (PJS) with synchronous rectal cancer who was treated with laparoscopic restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA). PJS is an autosomal dominant syndrome characterized by multiple hamartomatous polyps in the gastrointestinal tract, mucocutaneous pigmentation, and increased risks of gastrointestinal and nongastrointestinal cancer. This report presents a patient with a 20-year history of intermittent bloody stool, mucocutaneous pigmentation and a family history of PJS, which together led to a diagnosis of PJS. Moreover, colonoscopy and biopsy revealed the presence of multiple serried giant pedunculated polyps and rectal adenocarcinoma. Currently, few options exist for the therapeutic management of PJS with synchronous rectal cancer. For this case, we adopted an unconventional surgical strategy and ultimately performed laparoscopic restorative proctocolectomy with IPAA. This procedure is widely considered to be the first-line treatment option for patients with ulcerative colitis or familial adenomatous polyposis. However, there are no previous reports of treating PJS patients with laparoscopic IPAA. Since the operation, the patient has experienced no further episodes of gastrointestinal bleeding and has demonstrated satisfactory bowel control. Laparoscopic restorative proctocolectomy with IPAA may be a safe and effective treatment for patients with PJS with synchronous rectal cancer.

Role of Minimally Invasive Surgery in the Reoperative Abdomen or Pelvis

Laparoscopy has become widely accepted as the preferred surgical approach in the management of benign and malignant colorectal diseases. Once considered a relative contraindication in patients with prior abdominal surgery (PAS), as surgeons have continued to gain expertise in advanced laparoscopy, minimally invasive approaches have been increasingly incorporated in the reoperative abdomen and pelvis. Although earlier studies have described conversion rates, most contemporary series evaluating the impact of PAS in laparoscopic colorectal resection have reported equivalent conversion and morbidity rates between reoperative and non-reoperative cases, and series evaluating the impact of laparoscopy in reoperative cases have demonstrated improved short-term outcomes with laparoscopy. The data overall highlight the importance of case selection, careful preoperative preparation and planning, and the critical role of surgeons' expertise in advanced laparoscopic techniques. Challenges to the widespread adoption of minimally invasive techniques in reoperative colorectal cases include the longer learning curve and longer operative time. However, with the steady increase in adoption of minimally invasive techniques worldwide, minimally invasive surgery (MIS) is likely to continue to be applied in the management of increasingly complex reoperative colorectal cases in an effort to improve patient outcomes. In the hands of experienced MIS surgeons and in carefully selected cases, laparoscopy is both safe and efficacious for reoperative procedures in the abdomen and pelvis, with measurable short-term benefits.

Minimally invasive surgery for inflammatory bowel disease: Review of current developments and future perspectives

Patients with inflammatory bowel disease (IBD) comprise a population of patients that have a high likelihood of both surgical treatment at a young age and repetitive operative interventions. Therefore surgical procedures need to aim at minimizing operative trauma with best postoperative recovery. Minimally invasive techniques have been one of the major advancements in surgery in the last decades and are nowadays almost routinely performed in colorectal resections irrespective of underlying disease. However due to special disease related characteristics such as bowel stenosis, interenteric fistula, abscesses, malnutrition, repetitive surgeries, or immunosuppressive medications, patients with IBD represent a special cohort with specific needs for surgery. This review summarizes current evidence of minimally invasive surgery for patients with Crohn’s disease or ulcerative colitis and gives an outlook on the future perspective of technical advances in this highly moving field with its latest developments in single port surgery, robotics and trans-anal techniques.

Laparoscopic colorectal surgery: Current status and implementation of the latest technological innovations

The introduction of laparoscopy is an example of surgical innovation with a rapid implementation in many areas of surgery. A large number of controlled studies and meta-analyses have shown that laparoscopic colorectal surgery is associated with the same benefits than other minimally invasive procedures, including lesser pain, earlier recovery of bowel transit and shorter hospital stay. On the other hand, despite initial concerns about oncological safety, well-designed prospective randomized multicentre trials have demonstrated that oncological outcomes of laparoscopy and open surgery are similar. Although the use of laparoscopy in colorectal surgery has increased in recent years, the percentages of patients treated with surgery using minimally invasive techniques are still reduced and there are also substantial differences among centres. It has been argued that the limiting factor for the use of laparoscopic procedures is the number of surgeons with adequate skills to perform a laparoscopic colectomy rather than the tumour of patients’ characteristics. In this regard, future efforts to increase the use of laparoscopic techniques in colorectal surgery will necessarily require more efforts in teaching surgeons. We here present a review of recent controversies of the use of laparoscopy in colorectal surgery, such as in rectal cancer operations, the possibility of reproducing complete mesocolon excision, and the benefits of intra-corporeal anastomosis after right hemicolectomy. We also describe the results of latest innovations such as single incision laparoscopic surgery, robotic surgery and natural orifice transluminal endoscopic surgery for colon and rectal diseases.

Occult and Manifest Colorectal Carcinoma in Ulcerative Colitis: How Does It Influence Surgical Decision Making?

Background

The incidence of colorectal cancer (CRC) among patients with ulcerative colitis (UC) is increased compared to the general population. The diagnosis of CRC potentially influences surgical decision making in patients with UC.

Methods

This review considers clinical studies, systematic reviews, and guidelines on the surgical therapy of CRC in UC. We searched the bibliographic databases The Cochrane Library and Medline (applying MeSH terms such as ‘Colitis, Ulcerative/surgery’, ‘Colorectal Neoplasms’, and ‘Proctocolectomy, Restorative’) with no restriction on language, date, or country. Search results as well as references of relevant publications were independently screened by both authors of this review.

Results

The surgical gold standard for proven CRC in UC is oncological proctocolectomy, if possible preferably as a restorative procedure with formation of an ileal pouch-anal anastomosis. Mucosectomy and hand-sewn anastomosis is the preferred option for fashioning the anastomosis in these patients, especially in case of dysplasia or cancer in the rectum, although the available data is not conclusive. In highly selected cases of patients with histologically confirmed sporadic CRC without dysplasia in multiple random biopsies and without relevant inflammation, a conventional limited oncological resection is adequate. If UC patients with rectal cancer require radiotherapy, it should be performed in a neoadjuvant setting because of the high risk of radiation-induced pouch failure.

Conclusion

Although restorative proctocolectomy is clearly the gold standard therapy for patients with CRC in UC, surgical decision making has to take into account the various settings and patient factors.

Reduced-port laparoscopic restorative proctocolectomy without diverting ileostomy

INTRODUCTION

We introduced a reduced-port procedure for laparoscopic restorative proctocolectomy without diverting ileostomy for patients with familial adenomatous polyposis and ulcerative colitis.

MATERIALS AND SURGICAL TECHNIQUE

A multichannel port was inserted through a 2.5-cm umbilical incision. A 12-mm port in the right lower abdomen and a 3- or 5-mm port were also employed. A proctocolectomy was performed intracorporeally, and the entire colon and rectum were delivered through the umbilical incision. An ileal J-pouch was made extracorporeally following division of the mesenteric vessels. Ileal j-pouch-anal anastomosis was performed intracorporeally or transanally after rectal mucosectomy. A drain was inserted through the 12-mm port incision, and a transanal decompression tube was placed in the pouch. Two women and one man underwent this surgery, and their postoperative recovery was uneventful.

DISCUSSION

Laparoscopic restorative proctocolectomy without a diverting stoma by a reduced-port technique is feasible and provides excellent cosmetic outcomes in selected patients.

A think tank of the Italian Society of Colorectal Surgery (SICCR) on the surgical treatment of inflammatory bowel disease using the Delphi method: ulcerative colitis

The majority of patients suffering from ulcerative colitis (UC) are managed successfully with medical treatment, but a relevant number of them will still need surgery at some point in their life. Medical treatments and surgical techniques have changed dramatically in recent years, and available guidelines from relevant societies are rapidly evolving, providing UC experts with updated and valid practical recommendations. However, some aspects of the management of UC patients are still debated, and the application of guidelines in clinical practice may be suboptimal. The Italian Society of Colorectal Surgery (SICCR) sponsored the think tank in order to identify critical aspects of the surgical management of UC in Italy. The present paper reports the results of a think tank of Italian colorectal surgeons concerning surgery for UC and was not developed as an alternative to authoritative guidelines currently available. Members of the SICCR voted on several items proposed by the writing committee, based on evidence from the literature. The results are presented, focusing on points to be implemented. UC management relies on evaluations that need to be individualized, but points of major disagreement reported in this paper should be considered in order to develop strategies to improve the quality of the evidence and the application of guidelines in a clinical setting.

Surgical Principles in the Treatment of Ulcerative Colitis

Background

The primary treatment of ulcerative colitis (UC) is conservative; surgical intervention is carried out in the case of therapy-refractory situation, imminent or malignant transformation, or complications. Surgery for UC should be indicated by interdisciplinary means. Despite the development of drug therapy – in particular the introduction of biologics -, a surgical intervention becomes necessary in a relevant proportion of patients with UC throughout lifetime.

Methods

A selective literature search was conducted, taking into account the current studies, reviews, meta-analyses, and guidelines. PubMed served as a database. The present work gives an overview of the surgical options, outcome as well as peri- and postoperative management for patients with UC.

Results

Approximately 20% of patients with UC will require surgery during the course of their disease. The rate of colectomy after a disease duration of 10 years is at approximately 16%. Unlike Crohn's disease, UC is principally surgically curable since it is naturally limited to the colon and rectum. Restorative proctocolectomy with an ileal pouch-anal anastomosis represents the surgical treatment of choice. Large studies show a postoperative complication rate of around 30% and a low mortality of 0.1% for this procedure. Chronic pouchitis is one of the main factors limiting the surgical success of curing UC. Despite a high postoperative complication rate, there is a long-term pouch success rate of >90% after 10 and 20 years of follow-up.

Conclusion

A close cooperation between the various disciplines in the pre- and postoperative setting is essential for an optimal outcome of patients with UC. Despite a 30% rate of early postoperative complications, normal quality of life can ultimately be reached in more than 90% of patients in experienced centers.

Role of laparoscopic surgery in the treatment of ulcerative colitis; short- and mid-term results

OBJECTIVES

Laparoscopy is used more widely for the surgery of ulcerative colitis. The objective of this study was a comparison of the surgical and 3-year follow-up results of patients treated with conventional and minimally invasive methods.

MATERIALS AND METHODS

A total of 45 patients received surgery for ulcerative colitis, 16 as emergency and 29 as elective cases. Laparoscopy was used in 23 and a conventional method in 22 cases. No difference was found between the two groups from the aspects of American Society of Anesthesiologists physical status (ASA) class, mean body mass index (BMI) and age. There were 4 emergency cases in the laparoscopy group, and 12 in the open group. Nineteen elective surgeries were performed in the laparoscopy group, and 10 in the open group.

RESULTS

There was no significant difference between the groups as concerns the length of hospital or intensive care unit (ICU) stay, the time to bowel function recovery, but the duration of open surgery was significantly shorter. There was no difference between the groups in the rate of early postoperative complications, whereas among potential late complications, the rates of intestinal obstruction (8.7% vs. 45%) and a septic condition (0% vs. 27%) were significantly lower in the laparoscopy group. There was a significant improvement in the quality of life after surgery in both groups, and better cosmetic results were observed in the laparoscopy group.

CONCLUSION

Laparoscopy can be used for ulcerative colitis both emergency and elective cases, it provides a good quality of life and the mid-term rate of complications is lower as compared with open surgery.

Characterizing readmission in ulcerative colitis patients undergoing restorative proctocolectomy

BACKGROUND

Postoperative readmissions increase costs and affect patient quality of life. Ulcerative colitis (UC) patients are at a high risk for hospital readmission following restorative proctocolectomy (RP).

OBJECTIVE

The objective of this study is to characterize UC patients undergoing RP and identify causes and risk factors for readmission.

DESIGN

A retrospective review of a prospectively maintained institutional database was performed. Postoperative readmission rates and reasons for readmission were examined following RP. Univariate and multivariate analyses were performed to evaluate for risk factors associated with readmission.

RESULTS

Of 533 patients who met our inclusion criteria, 18.2 % (n = 97) were readmitted within 30 days while 22.7 % (n = 121) were readmitted within 90 days of stage I of RP. Younger patient age (OR 1.825, 95 % CI 1.139-2.957), laparoscopic approach (OR 1.943, 95 % CI 1.217-3.104), and increased length of initial stay (OR 1.155, 95 % CI 1.090-1.225) were all associated with 30-day readmission. The most common reason for readmission was dehydration/ileus/partial bowel obstruction, with 10 % of patients readmitted for this reason within 30 days.

CONCLUSIONS

Patients undergoing restorative proctocolectomy are at high risk for readmission, particularly following the first stage of the operation. Novel treatment pathways to prevent ileus and dehydration as an outpatient may decrease the rates of readmission following RP.

Outcomes and cost of diverted versus undiverted restorative proctocolectomy

BACKGROUND

Some observational studies suggest that diversion during restorative proctocolectomy mitigates the risk of anastomotic complications. However, diversion has its own costs and complications. The aim of this study was to compare the cost and outcomes of diverted to undiverted restorative proctocolectomy.

METHODS

This study took advantage of a natural experiment within one surgical department to understand the clinical and financial implications of diversion during restorative proctocolectomy. For the last 10 years, two surgeons routinely diverted all patients undergoing restorative proctocolectomy, and two other surgeons routinely did not. The medical records of 288 consecutive restorative proctocolectomy patients were reviewed. Minimum follow-up time was 1 year, with an average of 4.7 years. Complications rates and costs of care were collected.

RESULTS

There were no significant differences between rates of anastomotic leak, fistula, or hernias in diverted versus undiverted patients. The odds of having stricture (odds ratio (OR) = 17.08, P < 0.001) and small bowel obstruction (OR = 5.05, P = 0.02) were both significantly higher in diverted patients. The average cost per patient was $43,000 more in the routinely diverted patients.

CONCLUSION

Undiverted restorative proctocolectomy may be the highest value procedure with the most favorable outcomes at the lowest cost.
