Transanal proctocolectomy and ileal pouch-anal anastomosis (TaIPAA) for ulcerative colitis: medium term functional outcomes in a single centre

State of the Art: Pouch Surgery in the 21st Century

BACKGROUND

An ileoanal pouch with IPAA is the preferred method to restore intestinal continuity in patients who require a total proctocolectomy. Pouch surgery has evolved during the past decades thanks to increased experience and research, changes in the medical management of patients who require an ileal pouch, and technological innovations.

OBJECTIVE

To review the main changes in pouch surgery over the past 2 decades, with a focus on staging, minimally invasive and transanal approaches, pouch design, and anastomotic configuration.

RESULTS

The decision on the staging approach depends on the patient's conditions, their indication for surgery, and the risk of anastomotic leak. A minimally invasive approach should be performed whenever feasible, but open surgery still has a role in this technically demanding operation. Transanal IPAA may be performed in experienced centers and may reduce conversion to open surgery in the hostile pelvis. The J-pouch is the easiest, fastest, and most commonly performed design, but other designs may be used when a J-pouch is not feasible. A stapled anastomosis without mucosectomy can be safely performed in the majority of cases, with a low incidence of rectal cuff neoplasia and better functional outcomes than handsewn. Finally, Crohn's disease is not an absolute contraindication to an ileoanal pouch, but pouch failure may be higher compared to other indications.

CONCLUSIONS

Many technical nuances contribute to the success of an ileoanal pouch. The current standard of care is a laparoscopic J-pouch with double-stapled anastomosis, but this should not be seen as a dogma, and the optimal approach and design should be tailored to each patient. See video from symposium.

Controversies in IPAA for Ulcerative Colitis: A Systematic Review of Different Anastomotic Techniques

BACKGROUND

Available techniques for IPAA in ulcerative colitis include handsewn, double-stapled, and single-stapled anastomoses. There are controversies, indications, and different outcomes regarding these techniques.

OBJECTIVE

To describe technical details, indications, and outcomes of 3 specific types of anastomoses in restorative proctocolectomy.

DATA SOURCE

Systematic literature review for articles in the PubMed database according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria.

STUDY SELECTION

Studies describing outcomes of the 3 different types of anastomoses, during pouch surgery, in patients undergoing restorative proctocolectomy for ulcerative colitis.

INTERVENTION

IPAA technique.

MAIN OUTCOME MEASURES

Postoperative outcomes (anastomotic leaks, overall complication rates, and pouch function).

RESULTS

Twenty-one studies were initially included: 6 studies exclusively on single-stapled IPAA, 2 exclusively on double-stapled IPAA, 6 studies comparing single-stapled to double-stapled techniques, 6 comparing double-stapled to handsewn IPAA, and 1 comprising single-stapled to handsewn IPAA. Thirty-seven studies were added according to authors' discretion as complementary evidence. Between 1990 and 2015, most studies were related to double-stapled IPAA, either only analyzing the results of this technique or comparing it with the handsewn technique. Studies published after 2015 were mostly related to transanal approaches to proctectomy for IPAA, in which a single-stapled anastomosis was introduced instead of the double-stapled anastomosis, with some studies comparing both techniques.

LIMITATIONS

A low number of studies with handsewn IPAA technique and a large number of studies added at authors' discretion were the limitations of this strudy.

CONCLUSIONS

Handsewn IPAA should be considered if a mucosectomy is performed for dysplasia or cancer in the low rectum or, possibly, for re-do surgery. Double-stapled IPAA has been more widely adopted for its simplicity and for the advantage of preserving the anal transition zone, having lower complications, and having adequate pouch function. The single-stapled IPAA offers a more natural design, is feasible, and is associated with reasonable outcomes compared to double-stapled anastomosis. See video from symposium.

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.

Effect of comfort nursing on postoperative recovery and life quality of patients undergoing thoracic surgery

OBJECTIVE

To evaluate the effect of comfort nursing on postoperative recovery and life quality of patients undergoing thoracic surgery.

METHODS

A total of 400 patients undergoing thoracic surgery in our hospital from October 2017 to July 2020 were identified as research subjects and retrospectively studied. These patients were assigned to a control group (Con group, n=196, given conventional nursing) and an observation group (Obs group, n=204, given conventional nursing combined with comfort nursing) according to nursing modality. The following items of the two groups were compared: incidence of adverse reactions after surgery, MOS 36-Item Short-Form Health Survey (SF-36) score, visual analog scale (VAS) scores at 24, 48, and 72 h after surgery, length of stay, first postoperative exhaust time, drainage duration, nursing satisfaction, and systolic blood pressure (SBP), diastolic blood pressure (DBP), mean atrial pressure (MAP), and heart rate before and after the intervention.

RESULTS

Compared with the Con group, the Obs group showed a notably lower total incidence of adverse reactions and had higher SF-36 scores after surgery. The Obs group had lower VAS scores at 24, 48, and 72 h after surgery than the Con group. The Obs group also experienced significantly shorter length of stay and drainage duration and earlier first postoperative exhaust time in contrast to the Con group. In addition, the Obs group obtained a higher satisfaction rate than the Con group, and patients in the Obs group had better treatment compliance and emotionalal status than those in the Con group. Moreover, the two groups presented no significant difference in SBP, DBP, MAP, or heart rate before and after intervention (all P>0.05).

CONCLUSION

For patients undergoing thoracic surgery, comfort nursing can greatly improve their life quality and contribute to their postoperative recovery.

Psychosocial factors associated with j-pouch surgery for patients with IBD: a scoping review

BACKGROUND

Ulcerative colitis and Crohn's disease are subtypes of inflammatory bowel disease: a chronic condition of unclear etiology characterized by inflammation of the small and large intestine. Inflammatory bowel disease is managed with diet, medications, and surgeries, with the most common surgery, recommended to ulcerative colitis patients being j-pouch surgery.

PURPOSE

To assess the current literature concerning psychosocial factors associated with j-pouch surgery for patients with inflammatory bowel disease.

METHODS

A systematic scoping review of the empirical and grey literature was conducted for original research on j-pouch surgery and psychosocial variables. Eight databases were searched: Medline, PsychInfo, CINAHL, EBM Reviews, ProQuest Dissertations and Theses Global, ResearchGate, Prospero, and PrePubMed.

RESULTS

Thirty-nine articles were identified. Many studies (n = 18) adopted a case-series design, and none examined psychosocial interventions. The most popular psychosocial variables assessed were quality of life (n = 34) and those associated with sexual health and functioning (n = 9).

CONCLUSIONS

Despite being an established surgical procedure, little research has examined the psychosocial implications of j-pouch surgery. As such, clinicians lack a robust understanding of how this procedure affects patients' psychiatric and social status and adaptive abilities. There is a need for high-quality research utilizing validated measures and rigorous design methodologies with control populations.

Functional outcomes after transanal ileal pouch-anal anastomosis for ulcerative colitis: narrative review of the current literature

The transanal approach to ileal pouch-anal anastomosis (Ta-IPAA) for ulcerative colitis was introduced in 2015 and has since been shown to be a safe and feasible technique, although the impact of this approach on patient function remains unclear. A systematic literature review was performed to identify studies exploring functional outcomes and quality of life after Ta-IPAA. Seven papers were identified, which all demonstrated satisfactory functional outcomes after Ta-IPAA as measured by tools such as Cleveland Global Quality of Life (CGQOL), Oresland Score (OS), Pouch Functional Score (PFS), and Inflammatory Bowel Disease Questionnaire (IBDQ). Many gaps in the literature were identified including paucity of follow-up data beyond the 1-year mark, lack of fertility and fecundity assessment as functional outcomes, and limited evaluation of objective physiologic anal sphincter function. The Ta-IPAA therefore shows promise for good functional results in the short-term, although further research will be required to evaluate the stability of function over time as the technique becomes increasingly integrated into modern surgical practice.

Transanal ileal pouch anal anastomosis for ulcerative colitis in children and adults: a systematic review and meta-analysis

PURPOSE

The incidence of pediatric onset ulcerative colitis (UC) is increasing, with increasing rate of children eventually requiring surgical treatment. Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the preferred surgical treatment. Although transanal IPAA (ta-IPAA) is becoming widely accepted for adult UC patients, data regarding this procedure in children are scarce. Nevertheless, some adult publications also include patients under 18 years old. This systematic review and meta-analysis aimed to summarize surgical and functional outcomes following ta-IPAA, and extract conclusion regarding pediatric UC patients.

METHODS

PubMed, Cochrane Library databases, Embase, Web of science and Google Scholar databases were searched, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses [PRISMA] guidelines. The final search was updated in April 2022. Four comparative cohorts (n = 868) and 11 non-comparative case series (n = 241) were included. Six reports included children. Anastomotic leak, complications, operative time, conversion rate, length of stay and functional outcomes were examined.

RESULTS

A total of 1103 patients, ranging 9-79 years were included in this review. We found no difference in risk for anastomotic leak (OR 1.36, 95% CI 0.46-4.06), minor and major complications (OR 0.92, 95% CI 0.48-1.76 and OR 0.78 95% CI 0.36-1.69, respectively) comparing ta-IPAA to transabdominal IPAA. Short- and long-term follow-up showed satisfying functional outcomes and quality of life.

CONCLUSIONS

Our review suggests that ta-IPAA is not inferior to transabdominal IPAA. Implementation of this method in children is technically feasible due to familiarity with the dissection plane. Long-term functional outcomes and quality of life are paramount in the pediatric population and should be particularly investigated. Multicenter prospective studies are required to investigate pediatric UC patients undergoing ta-IPAA.

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.

Evolving Experimental Platforms to Evaluate Ulcerative Colitis

Ulcerative colitis (UC) is a multifactorial disease defined by chronic intestinal inflammation with idiopathic origins. It has a predilection to affect the mucosal lining of the large intestines and rectum. Management of UC depends upon numerous factors that include disease pathogenesis and severity that are maintained via medical or surgical means. Chronic inflammation that is left untreated or managed poorly from a clinical stance can result in intestinal ulceration accompanied by resulting physiological dysfunction. End-stage UC is mediated by surgical intervention with the resection of diseased tissue. This can lead to numerous health-related quality of life issues but is considered a curative approach. Regimens to treat UC are ever evolving and find their basis within various platforms to evaluate and treat UC. Numerous modeling systems have been examined to delineate potential mechanisms of action. However, UC is a heterogenous disease spanning unknown genetic origins coupled with environmental factors that can influence disease outcomes and related treatment procedures. Unfortunately, there is no one-size-fits-all model to fully assess all facets of UC. Within the context of this review article, the utility of various approaches that have been employed to gain insight into different aspects of UC will be investigated.

Transanal ileal pouch-anal anastomosis for ulcerative colitis: a single-center comparative study

BACKGROUND

Ileal pouch-anal anastomosis (IPAA) is the procedure of choice in patients with ulcerative colitis (UC) requiring surgery. Advantages of laparoscopic IPAA (lap-IPAA) compared to open surgery have been investigated. However, laparoscopic dissection in the pelvis is still a challenge. A transanal approach provides better access to lower pelvis and avoids multiple staple firings, which could reduce the risk of anastomotic complications. The aim of this study was to compare short-term outcomes of transanal proctectomy with IPAA (ta-IPAA) with conventional lap-IPAA in patients with UC.

METHODS

A single-center retrospective study was conducted on consecutive UC patients, treated at Copenhagen University Hospital, Hvidovre, undergoing either laparoscopic or transanal IPAA in the period between January 2013 and December 2020. Exclusion criteria were Crohn's disease, previous extensive abdominal surgery and impaired sphincter function. Primary outcomes were overall postoperative complications. Secondary outcomes were length of hospital stay and re-admissions. For comparison between ta-IPAA and lap-IPAA, the Mann-Whitney U test was used for continuous variables, and Chi-square and Fisher's exact test for categorical variables.

RESULTS

A total of 65 patients with ta-IPAA (34 males, 31 females, median age 31 years [range 12-66 years]) and 70 patients with lap-IPAA (35 males, 35 females, median age 26 years [range 12-66 years]) were included. There was no difference between ta-IPAA and lap-IPAA regarding age, sex, body mass index or American Society of Anesthesiologists class. The primary colectomy procedure was performed laparoscopically in 95% of the ta-IPPA and 91% of the lap-IPAA patients (p = 0.493). The mean time between total colectomy and IPAA was 15 and 9 weeks for ta-IPAA and lap-IPAA, respectively (p = 0.048). A higher proportion of patients with ta-IPAA were treated with biologics preoperatively (98 vs. 82%; p = 0.002). Patients with ta-IPAA had a significantly higher mean operative time compared to lap-IPAA (277 min vs. 224 min; p = 0.001). There was no difference in the overall postoperative complication rate (ta-IPAA: 23% vs. lap-IPAA: 23%; p = 0.99). Pouch-related complications occurred in 13% of the ta-IPAA patients and 29% of lap-IPPA patients (p = 0.402). There was no difference in the anastomotic leakage rates. Readmission rates were similar in the ta-IPAA and lap-IPAA group (26 vs. 29%; p = 0.85), including IPAA-related readmissions. The mean follow-up time was 24 and 75 months for ta-IPAA and lap-IPAA, respectively (p = 0.001), and the ileostomy closure rate was similar in both groups of patients (p = 0.96).

CONCLUSIONS

The ta-IPAA approach for UC is a safe procedure and offers acceptable short-time outcomes.

Safety of transanal ileal pouch-anal anastomosis for ulcerative colitis: a retrospective observational cohort study

Background

Colectomy with transanal ileal pouch-anal anastomosis (taIPAA) is a surgical technique that can be used to treat benign colorectal disease. Ulcerative colitis is the most frequent inflammatory bowel disease (IBD) and although pharmacological therapy has improved, colectomy rates reach up to 15%. The objective of this study was to determine anastomotic leakage rates and treatment after taIPAA as well as short- and long-term pouch function.

Methods

We conducted a retrospective analysis of a prospective database of all patients undergoing taIPAA at an academic tertiary referral center in Germany, between 01/03/2015 and 31/08/2019. Patients with indications other than ulcerative colitis or with adjuvant chemotherapy following colectomy for colorectal carcinoma were excluded for short- and long-term follow up due to diverging postoperative care yet considered for evaluation of anastomotic leakage.

Results

A total of 22 patients undergoing taIPAA during the study time-window were included in analysis. Median age at the time of surgery was 32 ± 12.5 (14–54) years. Two patients developed an anastomotic leakage at 11 days (early anastomotic leakage) and 9 months (late anastomotic leakage) after surgery, respectively. In both patients, pouches could be preserved with a multimodal approach. Twenty patients out of 22 met the inclusion criteria for short and long term follow-up. Data on short-term pouch function could be obtained in 14 patients and showed satisfactory pouch function with only four patients reporting intermittent incontinence at a median stool frequency of 9–10 times per day. In the long-term we observed an inflammation or “pouchitis” in 11 patients and a pouch failure in one patient.

Conclusion

Postoperative complication rates in patients with benign colorectal disease remain an area of concern for surgical patient safety. In this pilot study on 22 selected patients, taIPAA was associated with two patients developing anastomotic leakage. Future large-scale validation studies are required to determine the safety and feasibility of taIPAA in patients with ulcerative colitis.

TaTME approach as a rescue during a laparoscopic TME for high rectal cancer. A case report

•

There are several surgical approaches for patient with rectal cancer, depending on tumor stage and tumor distance from anal verge. Total mesorectal excision (TME) is the gold standard surgical technique for rectal tumors, reducing rectal cancer local recurrence.

•

Transanal total mesorectal excision (TaTME) has been described in rectal cancer treatment, especially in challenging patients with narrow pelvis, improving not only dissection but also the preservation of autonomic pelvic nerves and the achievement of a restorative procedure.

•

This case report aims to describe the possible use of TaTME procedure as a rescue also when this approach is not the first choice. In conclusion, we believe that, if performed by experienced surgeons, TaTME is safe and useful and could be used not in his conventional use.

Introduction and importance

In the last years, transanal total mesorectal excision (TaTME) has been described in rectal cancer treatment, especially in challenging patients, difficulties in pelvic exposure and limitations of instrumentation improving not only dissection but also the preservation of autonomic pelvic nerves and the achievement of a restorative procedure.

Here we report a case report of anterior laparoscopic rectal resection for adenocarcinoma of the high-mid rectum converted to transanal approach.

Case presentation

A 69-year-old male presented hepatic nodules during radiological follow-up for prostate cancer treated with radical prostatectomy and adjuvant radiotherapy (70 Gy). The biopsy of the lesion demonstrated the presence of a metastatic lesion of an adenocarcinoma, with suspected intestinal origin. Then, we perform an endoscopic examination, which showed the presence of a rectal lesion, which cause a bowel stenosis extended from the middle part to the upper part of the rectum.

After chemoradiotherapy, an anterior rectal resection was performed. During surgery we could not perform the resection of the rectum due the thickness and fibrosis of the tissue, despite we used different branded mechanical stapler. So, we decided to complete the surgical treatment starting a TaTME procedure with resolution of the problem.

Clinical discussion

TaTME is a relatively new technique that had already become a valid option in the treatment of low rectal cancer, and, nowadays, also in the treatment of inflammatory bowel disease. As reported in literature, this technique has a number of advantages, especially in narrow pelvis and it is very useful in low rectal surgery.

Conclusion

This case report aims to describe the possible use of TaTME procedure as a rescue also when this approach is not the first choice.
