Functional outcome and quality of life after stapled transanal rectal resection for obstructed defecation syndrome

Stapled Transanal Rectal Resection (Starr) in the Treatment of Obstructed Defecation: A Systematic Review

Obstructed defecation syndrome (ODS) is a form of constipation that influences the quality of life in most patients and is an important health care issue. In 2004 Longo introduced a minimal invasive trans-anal approach known as Stapled Trans-Anal Rectal Resection (STARR) in order to correct mechanical disorders such as rectocele or rectal intussusception, two conditions present in more than 90% of patients with ODS. Considering the lack of a common view around ODS and STARR procedure. the aim of our study is to review the literature about preoperative assessment, operative features and outcomes of the STARR technique for the treatment of ODS. We performed a systematic search of literature, between January 2008 and December 2020 and 24 studies were included in this review. The total number of patients treated with STARR procedure was 4,464. In conclusion STARR surgical procedure has been proven to be safe and effective in treating symptoms of ODS and improving patients Quality of Life (QoL) and should be taken in consideration in the context of a holistic and multi modal approach to this complex condition. International guidelines are needed in order to optimize the diagnostic and therapeutic process and to improve outcomes.

Standard stapled transanal rectal resection versus stapled transanal rectal resection with one high-volume stapler to prevent complications in the elderly

BACKGROUND

The causes of obstructed defecation syndrome (ODS) can actually be either functional or mechanical (primary or secondary deficit of the sensitivity, slow bowel transit, pelvic floor dyssynergia, internal and external rectal prolapse, recto-anal intussusceptions, anterior or posterior rectocele and pelvic prolapse of the bladder, uterus, bowel or sigma). The aim of our study was to evaluate the safety, efficacy and feasibility of stapled transanal rectal resection (STARR) procedure performed by a single or double stapler through clinical and functional outcomes for transanal stapled surgery.

METHODS

From January 2016 to October 2017, ninety patients with ODS secondary to rectal prolapse, anal-rectal intussusception and anterior rectocele, that underwent to a STARR procedure were enrolled. Thirty of these underwent a STARR procedure with double circular stapler PPH-01 (Group A); 30 with single circular stapler CPH34HV with a purse string suture (Group B); and 30 with single circular stapler CPH34HV with a "parachute technique" (Group C). All patients were selected with clinical examination, Wexner score for fecal incontinence and ODS score for constipation. Patients also underwent a Defeco RMN for an anatomical and dynamic evaluation of the pelvic floor.

RESULTS

No recurrence rates were observed in the three groups. The mean operative time was 46.3 minutes in group A; 34.5 minutes in group B; and 37.6 minutes in Group C. The volume of the resected specimen was 17 mL in group A; 15 mL in group B; and 16 mL in Group C. Complications were bleeding (3.3% in group A); fecal urgency (6.6% in group A, 10% in group B and 3.3% in group C); rectal hematoma (3.3% in group A). all symptoms significantly improved after the operation without differences between groups.

CONCLUSIONS

The STARR technique performed with a single stapler CPH34HV is safe, faster and less expensive than the STARR performed by a double PPH01. Besides, with the parachute technique, it is possible to resect asymmetric prolapses.

Expert consensus on the assessment and treatment of chronic constipation in the elderly

It is of significant importance to scientifically assess and efficiently address chronic constipation in the elderly population. Therefore, organizing some domestic experts of geriatrics and gastroenterology, we have formulated this consensus to reference for clinical staff.

[Intraoperative pitfalls and complications in defecation disorders and rectal prolapse]

BACKGROUND

No generally accepted gold standard exists for the operative therapy of rectal prolapse in its variety of manifestations. Existing evidence suggests that an individualized choice of procedure provides the best result for each single patient. Knowledge of possible pitfalls and intraoperative management of complications in frequently applied procedures are important prerequisites for reliable treatment of affected patients.

MATERIAL AND METHODS

A consecutive series of 233 patients (June 2011-May 2016) with individualized choice of operative procedure in patients with rectal prolapse and rectocele based on an algorithm for a clinical treatment pathway and stapled hemorrhoidopexy were included. Intraoperative pitfalls and complications and their management (iPCM) were prospectively documented and analyzed.

RESULTS

The iPCM could be classified into three different categories: group I: iPCM was immediately noted and intraoperatively treated with no impact on the further clinical course (n = 20), group II: iPCM was successfully treated conservatively within a short time after the procedure (n = 9) and group III: iPCM required surgical revision (n = 5).

CONCLUSION

Individualized treatment of rectal prolapse and rectocele requires a broad spectrum of methods in specialized coloproctology units. A clinical treatment pathway facilitates the optimal choice of procedure. Overall the complication rates during surgical treatment of transanal rectal prolapse are low; however, available operative procedures hold specific risks and knowledge of these risks helps to avoid them. Once complications occur, measures demonstrated in this study lead to normal clinical courses in the majority of cases.

[Transtar™ operation for rectocele and obstructed defecation syndrome]

The Contour® Transtar™ operation represents a further methodological development of conventional transanal stapled rectal resection (STARR) for the treatment of obstructed defecation syndrome (ODS) and/or full thickness rectal prolapse. In contrast to the conventional STARR technique a specially designed single curved stapler is used with which the rectal wall is incised in a circular fashion and anastomosed. This results in a monoblock resection with almost unlimited extent of resection. In multicenter studies the procedure has generally been shown to be effective for treatment of ODS with intussusception and rectocele. In comparison to conventional STARR the resected tissue samples are larger and the functional effectiveness is comparable. Furthermore, data from prospective randomized trials revealed higher effectiveness in long-term follow-up. With reference to full thickness rectal prolapse, feasibility studies have been performed which showed low morbidity but long-term follow-up studies suggest a high recurrence rate of >40 %.

Transanal surgery for obstructed defecation syndrome: Literature review and a single-center experience

Obstructed defecation syndrome (ODS) is a functional disorder commonly encountered by colorectal surgeons and gastroenterologists, and greatly affects the quality of life of patients from both societal and psychological aspects. The underlying anatomical and pathophysiological changes of ODS are complex. However, intra-rectal intussusception and rectocele are frequently found in patients with ODS and both are thought to play an important role in the pathogenesis of ODS. With the development of evaluation methods in anorectal physiology laboratories and radiology studies, a great variety of new operative procedures, especially transanal procedures, have been invented to treat ODS. However, no procedure has been proved to be superior to others at present. Each operation has its own merits and defects. Thus, choosing appropriate transanal surgical procedures for the treatment of ODS remains a challenge for all surgeons. This review provides an introduction of the current problems and options for treatment of ODS and a detailed summary of the essential assessments needed for patient evaluation before carrying out transanal surgery. Besides, an overview of the benefits and problems of current transanal surgical procedures for treatment of ODS is summarized in this review. A report of clinical experience of some transanal surgical techniques used in the authors' center is also presented.

STARR with CONTOUR® TRANSTAR™ device for obstructed defecation syndrome: one-year real-world outcomes of the European TRANSTAR registry

PURPOSE

Stapled transanal rectal resection (STARR) in patients with obstructive defecation syndrome (ODS) is limited by the capacity of the circular stapler used. This prospective cohort study was conducted to assess real-world clinical outcomes of STARR with the new CONTOUR® TRANSTAR™ device, shortly named TRANSTAR, at 12 months postoperatively.

METHODS

From January 2009 to January 2011, consecutive patients who underwent TRANSTAR in 22 European colorectal centers were enrolled in the study. Functional outcomes and quality of life were assessed by the changes in a number of scoring systems (Knowles-Eccersley-Scott-Symptom (KESS) score, ODS score, St. Mark's score, Euro Quality of Life-5 Dimension (EQ-5D) score, and Patient Assessment of Constipation-Quality of Life (PAC-QoL) score), at 12 months as compared to baseline. All complications were recorded and analyzed.

RESULTS

A total of 100 patients (98% female), mean age 60 years, were entered in the study. Statistically significant improvements were seen in the KESS (median 18 vs. 6; p < 0.01), ODS (median 15 vs. 4; p < 0.01), and PAC-Qol scores (median 2.10 vs. 0.86; p < 0.01). St. Mark's and EQ-5D scores improved nonsignificantly. Complications were reported in 11 % of patients, including bleeding (5%), staple line complications (3%), urinary retention (2%), and persistent pain (1%). No major complications or mortality occurred.

CONCLUSION

TRANSTAR facilitated a tailored, real circumferential full-thickness rectal resection, leading to improved patient functional and quality of life outcomes at 12 months postoperatively. It represents a safe and effective treatment for ODS in local clinical practice, although the sustainability of real-world results needs to be proven in the long-term follow-up.

Stapled transanal rectal resection (STARR) for obstructive defaecation syndrome: patients with previous pelvic floor surgery have poorer long-term outcome

AIM

Stapled transanal rectal resection (STARR) is used for patients with obstructive defaecation syndrome (ODS) not responding to conservative management. Reports indicate mixed results and there are no studies publishing the long-term outcome.

METHOD

Following full investigation, 37 patients with ODS underwent a STARR procedure by one of the authors (SP) between 2005 and 2010.

RESULTS

The median (range) patient age was 53.0 (28-79) years and all were female. Median (range) follow up was 13 (0-57) months, and nine (24.3%) patients were followed for longer than 24 months. Eighteen patients had undergone at least one (and often multiple) previous gynaecological procedures, including hysterectomy (n = 14), colposuspension (n = 3), vaginal rectocele repair (n = 4) and pelvic floor repair (n = 5). Four patients had had at least one previous rectal operation [stapled anopexy (n = 3) and Delorme's procedure (n = 2)]. One patient did not attend for postoperative follow up. Of the remaining 36 patients, 18 had resolution of obstructive symptoms. Of the 18 with residual symptoms, 17 eventually reported the same level of symptoms as before the STARR procedure. There was a significant correlation between the presence of residual symptoms and long-term ODS recurrence (P < 0.0005). For those with residual symptoms, the mean (95% CI) time to symptom recurrence was 3 (2.86-11.81) months. Twenty (56%) patients were satisfied with the outcome from the STARR procedure.

CONCLUSION

Residual symptoms are a strong indicator of long-term failure. STARR was effective for symptom resolution in 50% of patients. Those who had undergone pelvic floor or rectal prolapse surgery were significantly more likely to experience recurrent symptoms.

Internal Delorme's procedure for rectal outlet obstruction

AIM

The outcome of the internal Delorme's procedure (IDP) for obstructed defaecation was assessed.

METHOD

From October 2001 to March 2009, 167 patients with obstructed defaecation associated with rectal intussusception were operated on. Patients were selected on the basis of validated constipation and continence scores, clinical examination and defaecography. Seventy-six patients were treated by the IDP alone and 91 patients were treated by the IDP with a levatorplasty. Before surgery and after a mean ± SD follow up of 3.0 ± 1.5 years, patients were assessed using the Cleveland Clinic Incontinence and Constipation Score (CCIS and CCCS), the Obstructed Defecation Score (ODS), faecal urgency and the Patient Assessment of Constipation Quality of Life (PAC-QoL) questionnaire.

RESULTS

Seventeen (10.2%) patients developed a postoperative complication including fissure-in-ano (4.2%), proctalgia (3.0%), suture-line dehiscence with stenosis (1.8%) and Clostridium difficile colitis (1.2%). Faecal urgency changed from 22% to 17.6% (P = 0.754). Tenesmus fell from 53.9% to 17.1% (P < 0.001). The CCCS and the ODS fell by 50% or more in 82.6% and 73.7% of the patients, respectively. The CCIS did not worsen significantly in patients who remained incontinent, and 45.7% of the previously incontinent patients regained normal continence. The CCCS decreased from 11 to 3 (P < 0.001) in the patients treated by the IDP and from 12 to 3 (P < 0.001) in the patients treated by the IDP with levatorplasty. The overall recurrence rate was 5.4%. The PAC-QoL showed a reduction of anxiety/depression and of physical and psychological discomfort (P < 0.001).

CONCLUSION

The IDP is an effective and safe option for rectal outlet obstruction caused by rectal intussusception with excellent function and patient satisfaction.

Long-term outcome after transanal rectal resection in patients with obstructed defecation syndrome

BACKGROUND

Stapled transanal rectal resection with a new, curved, multifire stapler (Transtar procedure) has shown promising short- and midterm results for treating obstructed defecation syndrome. However, few results have been published on long-term outcome.

OBJECTIVE

This study aimed to investigate long-term functional results and quality of life after the Transtar procedure.

DESIGN

This is a retrospective study.

SETTING

This study was conducted at a tertiary hospital in Switzerland.

PATIENTS

Seventy consecutive patients (68 female) with obstructed defecation syndrome had a median age of 65 years (range, 20-90).

INTERVENTION

The Transtar procedure was performed between January 2007 and March 2010.

MAIN OUTCOME MEASURES

Postoperative functional results were evaluated with the Symptom Severity Score, Obstructed Defecation Score, and Cleveland Incontinence Score. Quality of life was evaluated with the Fecal Incontinence Quality of Life Score and the SF-36 Health Survey. Data were divided into 4 groups of 1-, 2-, 3-, and 4-year follow-ups.

RESULTS

The functional scores showed significant postoperative improvement throughout the studied period (p = 0.01). The quality-of-life scores showed a tendency for improvement only in the mental components on the SF-36 Health Survey (p = 0.01). Sixteen patients reported postoperative fecal urgency, but this subsided within a few months. Nine patients reported new postoperative episodes of incontinence and required further treatment.

LIMITATIONS

This study was limited by its retrospective nature, the selection bias, and a bias by the small number of questionnaires available for some scores.

CONCLUSION

The Transtar procedure was successful for long-term treatment of obstructed defecation syndrome. Fecal urgency and incontinence were observed, but typically resolved within months. Therefore, the Transtar procedure appears to be a reasonable approach to treating obstructed defecation syndrome in the long term.

Stapled transanal rectal resection with contour transtar for obstructed defecation syndrome: lessons learned after more than 3 years of single-center activity

BACKGROUND

Obstructed defecation syndrome is a widespread and disabling disease.

OBJECTIVE

We aim to evaluate the safety and efficacy of stapled transanal rectal resection performed with a new dedicated curved device in the treatment of obstructed defecation syndrome.

DESIGN

A retrospective review of 187 stapled transanal rectal resections performed from June 2007 to February 2011 was conducted.

SETTINGS

The entire study was conducted at a university hospital.

PATIENTS

: All the patients with symptomatic obstructed defecation syndrome and the presence of a rectocele and/or a rectorectal or rectoanal intussusception, in the absence of sphincter contractile deficiency, were included in the treatment protocol.

INTERVENTIONS

All procedures were performed with the use of the Contour Transtar device. We analyzed the functional results of this technique, the incidence and features of the surgical and functional complications, and ways to prevent or treat them.

MAIN OUTCOME MEASURES

Constipation was graded by using the Agachan-Wexner constipation score; use of aids to defecate and patient satisfaction were assessed preoperatively and 6 months after surgery. Intraoperative and postoperative complications were also investigated.

RESULTS

The constipation intensity was statistically reduced from the preoperative mean value of 15.8 (± 4.9) to 5.2 (± 3.9) at 6 months after surgery (p < 0.0001). Of the 151 (80.3%) patients who took laxatives and the 49 (26.2%) who used enemas before treatment, only 25 (13.2%; p < 0.0001) and 7 (3.7%; p < 0.0001) continued to do so after surgery. None of the 17 (9.1%) patients who had previously helped themselves with digitations needed to continue this practice. Almost all patients showed a good satisfaction rate (3.87/5) after the procedure.

LIMITATIONS

Limitations are the short follow-up of 1 year and the design of the study that may introduce potential selection bias.

CONCLUSIONS

The results of this study show that stapled transanal rectal resection performed with the use of the Contour Transtar is a safe and effective procedure to treat obstructed defecation syndrome.

Modified technique for performing STARR with Contour Transtar™

Stapled Transanal Rectal Resection (STARR) performed using CCS-30 Contour Transtar™ despite its recent introduction seems to be an effective surgical procedure to treat obstructed defecation syndrome. The major constraint of this procedure is the need to open the prolapse longitudinally using the CCS-30. This is often difficult and can lead to an inadequate or spiralling resection. Our modified technique, presented in this paper, creates the prolapse opening with an electric scalpel between two Kocher clamps, placed to grab the whole prolapsed tissue at 2 and 4 o'clock, respectively. The results of the first 83 procedures confirm that this technique allows the surgeon to simplify the prolapse's longitudinal opening and especially the first loading of the tissue between the CCS-30 jaws, which is necessary to start the circular resection, as confirmed by the absence of spiralling and major complications in this series.

Feasibility and safety study of day-case Transtar™ procedure

BACKGROUND

Short hospitalization surgery is cost effective and convenient for both patients and healthcare system. Stapled transanal rectal resection (STARR) conducted with the new curved device, Contour Transtar, has proved an effective and safe procedure for treatment of obstructed defecation syndrome. The aim of this study was to determine the safety and feasibility of STARR, performed as a day-case procedure.

MATERIAL AND METHODS

Retrospective review was performed of all STARR performed as day-case surgery between September 2009 and February 2011. The entire study (intervention, data collection and data analysis) was conducted at the One-day Surgery Unit of the St. Andrea Hospital, Rome, Italy. All patients with surgical indication to STARR for the presence of an obstructed defecation syndrome were included in the study. We excluded from day-case protocol, patients over 65 years old, with an ASA score of III-IV or with a BMI over 35. The surgical technique reflects the original technique proposed by Antonio Longo with the exception of the longitudinal prolapse opening, which was created with the use of an electric scalpel between two Kocher clamps and not by an application of Transtar stapler. To evaluate the feasibility and safety of performing this procedure with short hospitalization, we investigated the presence and the time of presentation of post-operative complications.

RESULTS

Eighty-nine patients underwent STARR as a day-case regimen, and none presented major complications or required an extension of hospital stay or readmission.

CONCLUSIONS

STARR performed with Contour Transtar, in selected patients, is safe and feasible in day-case regimen if performed by expert surgeons and in a structure that allows the physician to keep the patient hospitalized or to re-admit and promptly treat those patients who present major surgical complication.

Functional and morphologic outcome after stapled transanal rectal resection for obstructed defecation syndrome

BACKGROUND

Stapled transanal rectal resection is a novel surgery for obstructed defecation syndrome. Few data on the functional and morphologic outcome after the surgery have been reported.

OBJECTIVE

This study aimed to evaluate the functional and morphologic outcome after stapled transanal rectal resection.

DESIGN

This is a prospective study of consecutive patients undergoing transanal rectal resection.

SETTING

The study was conducted at a tertiary referral hospital, Beijing, China, from May 2007 to May 2009.

PARTICIPANTS

Eighty-six consecutive female patients with obstructed defecation syndrome were carefully selected.

INTERVENTIONS

All patients underwent stapled transanal rectal resection.

MAIN OUTCOME MEASURES

The main outcome measures were patients' symptoms, obstructed defecation syndrome score, Wexner incontinence score, anorectal manometry and defecography before and 1 year after surgery.

RESULTS

The occurrence of all symptoms were significantly reduced after the procedure (P < .0001). Obstructed defecation syndrome score was decreased from 18.17 ± 4.68 preoperatively to 7.36 ± 3.52 postoperatively (P < .0001) with the Wexner incontinence score unchanged. Maximum tolerable rectal volume was significantly decreased (236.08 ± 50.00 vs 205.25 ± 29.60, P < .0001) after surgery with anal sphincter pressures unchanged. Postoperative defecography was performed in 64 patients. Rectocele disappeared in 40 of 62 patients. The depth of rectocele was reduced from 35.40 ± 4.58 mm preoperatively to 19.77 ± 9.19 mm postoperatively (P < .0001). Incomplete evacuation disappeared in 41 of 51 patients. Intussusception was completely corrected in 39 of 56 patients. The reduction of obstructed defection syndrome score was greater in patients with both rectocele and intussusception corrected than others (12.75 ± 2.24 vs 9.17 ± 3.47; P < .0001).

LIMITATIONS

This study was limited owing to the lack of a control group and the medium-term results.

CONCLUSIONS

Stapled transanal rectal resection is an effective procedure for obstructed defecation syndrome. The functional outcome is good with the preservation of sphincter function and continence postoperatively. The morphologic outcome confirmed its efficacy in correcting rectocele and intussusception, and correlated well with clinical improvement.
