Endoscopic Management of Difficult Biliary Stones: An Evergreen Issue

Choledocholithiasis is one of the most common indications for endoscopic retrograde cholangiopancreatography (ERCP) in daily practice. Although the majority of stones are small and can be easily removed in a single endoscopy session, approximately 10-15% of patients have complex biliary stones, requiring additional procedures for an optimum clinical outcome. A plethora of endoscopic methods is available for the removal of difficult biliary stones, including papillary large balloon dilation, mechanical lithotripsy, and electrohydraulic and laser lithotripsy. In-depth knowledge of these techniques and the emerging literature on them is required to yield the most optimal therapeutic effects. This narrative review aims to describe the definition of difficult bile duct stones based on certain characteristics and streamline their endoscopic retrieval using various modalities to achieve higher clearance rates.

Orlando protocol for single session ductal clearance of common bile duct stones at ERCP

OBJECTIVES

Approach to management of common bile duct stones (CBDS) by endoscopic retrograde cholangiopancreatography (ERCP) is not standardized. We examined outcomes by applying predetermined protocol for CBDS management.

METHODS

When standard extraction techniques failed at ERCP, presence of tapered bile duct and stone-duct ratio were calculated. Large balloon sphincteroplasty (LBS) and/or mechanical (ML)/single-operator cholangioscopy-guided lithotripsy (SOCL) was performed based on presence of tapered bile duct and stone-duct mismatch. Primary outcome was single-session ductal clearance. Secondary outcome was adverse events.

RESULTS

Of 409 patients treated over 16 months, 321 (78.5%) had no tapered bile duct or stone-duct mismatch and single-session ductal clearance was achieved using standard techniques in 99.7% over median duration of 14 minutes (IQR 9-21 mins). Of 88 (21.5%) patients with difficult CBDS, tapered duct was seen in 79 (89.8%) and/or stone-duct mismatch in 36 (40.9%). Single-session ductal clearance was achieved in all 88 patients (100%) by LBS in 79 (89.8%), ML in 20 (22.7%) and SOCL in 16 (18.2%) over median duration of 29 minutes (IQR 17-47 mins). Overall, single-session ductal clearance was achieved in 99.8% with adverse events in 17 (4.2%) that included perforation in 2, post-sphincterotomy bleeding in 1, and mild/moderate post-ERCP pancreatitis in 14 patients.

CONCLUSIONS

A predetermined protocol optimized outcomes by enabling single-session ductal clearance of CBDS with high technical success and low adverse events.

Application of nanofat for treatment of traumatic faecal incontinence after sphincteroplasty - A pilot study

AIM

The aim of this study was to investigate whether the application of nanofat containing stem cells improves continence in women who had previously undergone anal sphincteroplasty with unsatisfactory long-term outcomes.

METHOD

This prospective pilot study included nine women with various degrees of anal incontinence who had previously undergone anal sphincteroplasty due to obstetric trauma. In all patients, the Wexner Incontinence Score (WS) and Faecal Incontinence Quality of Life Score (FIQLS), as well as anal manometry and endoanal ultrasound measurements, were performed before the procedure and during follow-up. In all patients, liposuction was performed and 50 ml of raw lipoaspirate was obtained and processed using a NanoFat Kit device. Approximately 20 ml of the mechanically emulsified and filtrated fat was obtained and the anal sphincter complex was infiltrated with it. Patient follow-up was conducted in person or via telephone 6 and 12 months after the procedure.

RESULTS

The squeeze pressure was significantly increased 6 months after the procedure (p = 0.01). The external anal sphincter measured at the 12 o'clock position was significantly thicker (p = 0.04). A significant decrease in the WS was observed both 6 and 12 months after the procedure compared with baseline values (p < 0.05 for both).

CONCLUSION

This study is the first to show that the application of nanofat as an injectable product improves continence in patients with unsatisfactory results after sphincteroplasty, suggesting it to be a promising and effective therapeutic tool. The procedure is safe and can be easily performed as an ambulatory procedure.

Repair of episiotomy and obstetrical perineal lacerations (first-fourth)

Perineal injury after vaginal delivery is common, affecting up to 90% of women. Perineal trauma is associated with both short- and long-term morbidity, including persistent pain, dyspareunia, pelvic floor disorders, and depression, and may negatively affect a new mother's ability to care for her newborn. The morbidity experienced after perineal injury is dependent on the type of laceration incurred, the technique and materials used for repair, and the skill and knowledge of the birth attendant. After all vaginal deliveries, a systematic evaluation including visual inspection and vaginal, perineal, and rectal exams is recommended to accurately diagnose perineal lacerations. Optimal management of perineal trauma after vaginal birth includes accurate diagnosis, appropriate technique and materials used for repair, providers experienced in perineal laceration repair, and close follow-up. In this article, we review the prevalence, classification, diagnosis, and evidence supporting different closure methods for first- through fourth-degree perineal lacerations and episiotomies. Recommended surgical techniques and materials for different perineal laceration repairs are provided. Finally, best practices for perioperative and postoperative care after advanced perineal trauma are reviewed.

Multimodal Management of Fecal Incontinence Focused on Sphincteroplasty: Long-Term Outcomes from a Single Center Case Series

The management of patients with fecal incontinence and an external anal sphincter (EAS) defect remains controversial. A retrospective series of overlapping anal sphincteroplasties performed between 1985−2013 from a single center, supplemented by selective puborectalis plication and internal anal sphincter repair is presented. Patients were clinically followed along with anorectal manometry, continence scoring (Cleveland Clinic Incontinence Score—CCS) and patient satisfaction scales. Patients with a suboptimal outcome were managed with combinations of biofeedback therapy (BFT), peripheral tibial nerve stimulation (PTNS), sacral nerve stimulation (SNS) or repeat sphincteroplasty. There were 120 anterior sphincter repairs with 90 (75%) levatorplasties and 84 (70%) IAS repairs. Over a median follow-up of 120 months (IQR 60−173.7 months) there were significant improvements in the recorded CCIS values (90.8% with a preoperative CCIS > 15 vs. 2.5% postoperatively; p < 0.001). There were 42 patients who required ancillary treatment with four repeat sphincteroplasties, 35 patients undergoing biofeedback therapy, 10 patients treated with PTNS and three managed with SNS implants with an ultimate good functional outcome in 92.9% of cases. No difference was noted in ultimate functional outcome between those treated with sphincteroplasty alone compared with those who needed ancillary treatments (97.1% vs. 85.7%, respectively). Overall, 93.3% considered the outcome as either good or excellent. Long-term functional outcomes of an overlapping sphincteroplasty are good. If the initial outcome is suboptimal, response to ancillary treatments remains good and patients are not compromised by a first-up uncomplicated sphincter repair.

[Postpartum fecal incontinence. State of the problem]

A review of the current national and foreign literature is devoted to epidemiology, risk factors, causes, diagnosis and modern treatment approaches for fecal incontinence (FI). Incidence of FI in early and delayed period after childbirth is 30% or more. At the same time, up to 87% of postpartum injuries of anal sphincter remain undiagnosed. Importantly, routine caesarean section does not reduce the risk of incontinence. In addition to typical complaints of spontaneous gas and stool, diagnosis of FI after childbirth includes transrectal ultrasound, MRI, anorectal manometry and pudendal nerve terminal motor latency testing. Survey of proctologists from different regions of Russia revealed a high demand from medical community for educational programs devoted to diagnosis, treatment and rehabilitation of patients with postpartum perineal injuries.

Diagnosis and management of fecal incontinence in children and adolescents

Fecal incontinence (FI) is a commonly occurring disease of high concern. It is characterized by voluntary and involuntary defecation in children and adolescents. It is not only a physical disease but also a psychological and behavioral disorder. FI poses a serious burden on individuals and their families and therefore has become a social problem. Unfortunately, the management of FI among children is still a challenge because the etiology varies widely. Constipation has been found to be the most common cause, while sphincter dysfunction and neurogenic abnormalities may also play a role. Currently, no consensus guidelines exist, and the criteria for selecting optional methods remain unclear. It is therefore necessary to improve the efficacy of diagnosis and management strategies of FI in children. This review focused on the classification and etiology, discussed the diagnosis and management methods of FI in children and adolescents, and aimed to guide future studies.

Is fistulotomy with immediate sphincter reconstruction (FISR) a sphincter preserving procedure for high anal fistula? A systematic review and meta-analysis

AIM

This systematic review aimed to assess the outcomes of fistulotomy or fistulectomy and immediate sphincter repair (FISR) in relation to healing, incontinence and sphincter dehiscence both overall and in patients with high anal fistulae.

METHODS

Medline, Embase and The Cochrane library were searched for studies of patients undergoing FISR for anal fistula. Data regarding healing, continence and sphincter dehiscence were extracted overall and for high anal fistulae. The DerSimonian-Laird random-effects method was used for pooled analysis, heterogeneity between studies was assessed based on the significance of between-study heterogeneity, and on the size of the I²  value. Risk of bias was assessed using the Cochrane risk of bias tool and the Newcastle-Ottawa scale.

RESULTS

We identified 21 studies evaluating 1700 patients. Pooled analysis of healing reached 93% (95% CI: 91%-95%, I²  = 51% p-value for heterogeneity = 0.004), with continence disturbance and worsening continence reaching 11% (95% CI: 6%-18%, I²  = 87% p < 0.001) and 8% (95% CI: 4%-13%, I²  = 74% p < 0.001), respectively. Subgroup analysis according to fistula height could only be conducted on limited data. Pooled healing in high anal fistulae was 89% (95% CI: 84%-94%, I²  = 76% p < 0.001), 16% suffered disturbance of continence (95% CI: 7%-27%, I²  = 89% p < 0.001), 8% worsening continence from baseline (95% CI: 2%-16%, I²  = 80% p < 0.001) and 2% suffered sphincter dehiscence (95% CI: 0%-10%, I²  = 89% p < 0.001).

CONCLUSION

The evidence suggests FISR is a safe, effective procedure. However, data are limited by inconsistencies in reporting of continence and definition of fistula height, particularly high anal fistulae. Significant heterogeneity means that outcomes in high fistulae remain uncertain.

Percutaneous removal of common bile duct stones using a modified balloon technique

To evaluate the effectiveness of percutaneous removal of common bile duct (CBD) stones using a modified balloon technique (balloon catheter sphincteroplasty and expulsion of the stones using half-captured balloons within the sheath) in patients difficult to treat with endoscopy.Fifty patients underwent a modified balloon technique (balloon group), and 53 patients underwent CBD stone removal by the basket method (stone basket group) between 2016 and 2019. We compared the balloon and stone basket groups to evaluate the effectiveness of the modified balloon technique. Outcome variables such as demographics, technical success rates, procedural details, and complications were analyzed. Statistical analysis was performed using Student t test, Fisher exact test, or the χ2 test.The technical success rate in the balloon group was 66% (33/50) in 1 session, 32% (16/50) in 2 sessions, and 2% (1/50) in 3 sessions. That of the stone basket group was 45% (24/53) in 1 session, 38% (20/53) in 2 sessions, and 17% (9/53) in 3 sessions.The total procedure time was significantly shorter in the balloon group (29.5 ± 15.1 minutes) than in the stone basket group (41.7 ± 20.2 minutes) (P < .01), whereas the number of stones was higher in the balloon group than in the stone basket group (P = .03). Maximal stone size, balloon size, pancreatitis, and hospitalization stay did not show statistical differences between the 2 groups. Most complications (9 patients, balloon group; 8 patients, stone basket group) were mild and transient. Major complications occurred in one patient in the stone basket group, who experienced hemobilia due to arterial injury caused by percutaneous transhepatic biliary drainage, which was treated by endovascular embolization without mortality.The modified balloon technique is an effective and safe treatment method for CBD stone removal in patients presenting difficulties in the endoscopic approach.

Changing paradigm of sacral neuromodulation and external anal sphincter repair for faecal incontinence in specialist centres

AIM

The aim of this study was to determine whether the paradigm of surgical intervention for faecal incontinence (FI) has changed between 2000 and 2013.

METHOD

This was a multi-centre retrospective study of patients who had undergone either sacral neuromodulation (SNM) or delayed sphincter repair or sphincteroplasty (SR) as a primary surgical intervention for FI in five centres in Europe and one in the United States. The flow of patients according to the intervention, sustainability of the treatment at a minimum follow-up of 5 years, complications and requirement for further interventions were recorded.

RESULTS

A total of 461 patients (median age 56 years, range 24-90 years, 41 men) had either SNM or SR as an index operation during the study period [SNM 284 (61.6%), SR 177 (38.4%)]. Among SNM patients, there were 169 revisional operations (change of battery and/or lead, re-siting or removal). At the time of last follow-up 203 patients (71.4%) continued to use SNM. Among SR patients, 30 (16.9%) had complications, most notably wound infection (22, 12.4%). During follow-up 32 patients (18.1%) crossed over to SNM. Comparing two 4-year periods (2000-2003 and 2007-2010), the proportion of patients operated on who had a circumferential sphincter defect of less than 90° was 48 (68%) and 45 (46%), respectively (P = 0.03), while those who had SNM as the primary intervention increased from 29% to 89% (P < 0.05).

CONCLUSION

The paradigm of surgical intervention for FI has changed with increasing use of SNM.

Current Position of Sacral Neuromodulation in Treatment of Fecal Incontinence

Fecal incontinence (FI) is defined as uncontrolled passage of feces or gas for at least 1-month duration in an individual who previously had control. FI is a common and debilitating condition affecting many individuals. Continence depends on complex relationships between anal sphincters, rectal curvatures, rectoanal sensation, rectal compliance, stool consistency, and neurologic function. Factors, such as pregnancy, chronic diarrhea, diabetes mellitus, previous anorectal surgery, urinary incontinence, smoking, obesity, limited physical activity, white race, and neurologic disease, are known to be the risk factors for FI. Conservative/medical management including biofeedback are recognized as the first-line treatment of the FI. Those who are suitable for surgical intervention and who have failed conservative management, sacral nerve stimulation (SNS) has emerged as the treatment of choice in many patients. The surgical technique involves placement of a tined lead with four electrodes through the S3 sacral foramen. The lead is attached to a battery, which acts as a pulse generator, and is placed under the patient's skin in the lower lumbar region. The use of SNS in the treatment of FI has increased over the years and the beneficial effects of this treatment have been substantiated by multiple studies. This review describes SNS as a modality of treatment for FI and its position in the current medical diaspora in patients with FI.

LONG-TERM EVOLUTION OF CONTINENCE AND QUALITY OF LIFE AFTER SPHINCTEROPLASTY FOR OBSTETRIC FECAL INCONTINENCE

Purpose

This study was performed to evaluate the long-term evolution of continence and patient’s quality of life after surgical treatment for obstetric fecal incontinence.

Methods

A prospective longitudinal study was conducted including consecutive patients who underwent sphincteroplasty for severe obstetric fecal incontinence. The first phase analyzed changes in continence and impact on quality of life. The second phase studied the long-term evolution reevaluating the same group of patients 6 years later. Degree of fecal incontinence was calculated using the Cleveland Clinic Score (CCS). Quality of life assessment was carried out with the Fecal Incontinence Quality of Life scale.

Results

Thirty-five patients with median age of 55 years (range, 28 to 73 years) completed the study. Phase 1 results: after a postoperative follow-up of 30 months (4 to 132 months), CCS had improved significantly from a preoperative of 15.7 ± 3.1 to 6.1 ± 5.0 (P < 0.001). Phase 2 results: median follow-up in phase 2 was 110 months (76 to 204 months). The CCS lowered to 8.4 ± 4.9 (P = 0.04). There were no significant differences between phases 1 and 2 in terms of quality of life; lifestyle (3.47 ± 0.75 vs. 3.16 ± 1.04), coping/behavior (3.13 ± 0.83 vs. 2.80 ± 1.09), depression/self-perception (3.65 ± 0.80 vs. 3.32 ± 0.98), and embarrassment (3.32 ± 0.90 vs. 3.12 ± 1.00).

Conclusion

Sphincteroplasty offers good short-medium term outcomes in continence and quality of life for obstetric fecal incontinence treatment. Functional clinical results deteriorate over time but did not impact on patients’ quality of life.

Secondary sphincter repair for anal incontinence following obstetric sphincter injury: functional outcome and quality of life at 18 years of follow-up

AIM

Secondary sphincter repair has been the conventional management of anal incontinence (AI) when a structural defect in the sphincter is recognized. However, disappointing long-term results have contributed to a tendency towards an increasing use of alternative treatment methods. This study aimed to assess the long-term functional outcomes following a secondary sphincter repair in women with AI after obstetric sphincter injury.

METHOD

This is a questionnaire study of women who underwent a secondary sphincter repair in Denmark between January 1990 and December 2005. Patients were identified through the Danish National Patient Registry. Functional outcomes were assessed by a self-administered questionnaire in 2010 and 2018. Primary outcomes were Wexner and St. Mark's scores. Impact on quality of life was assessed using the Fecal Incontinence Quality of Life Scale.

RESULTS

Functional outcome was assessed in 370 women in 2010 and 255 women in 2018. At 18.3 [interquartile range (IQR 15.0-22.0)] years of follow-up, the mean ± SD Wexner score was 8.8 ± 4.8 and the mean St. Mark's score was 11.7 ± 5.0. Flatus incontinence was the most frequent symptom, reported by 97%. Incontinence for liquid and solid stools was reported by 75% and 54%, respectively. There were no significant changes in incontinence frequencies over time. Women with a Wexner score of ≥ 9 had a significantly lower quality of life score in all domains than did women with a Wexner score of < 9 (P < 0.001).

CONCLUSION

At long-term follow-up, few patients are fully continent following a secondary sphincter repair. However, it appears that the functional results remain stable at very long-term follow-up.

A surgical technique for secondary repair of obstetric anal sphincter injuries; sphinctero-vagino-perineoplasty

Objective:

This study was conducted to present the preliminary results of seven patients treated with sphinctero-vagino-perineoplasty for secondary repair of obstetric anal sphincter injuries.

Materials and Methods:

This retrospective study was conducted on the records of seven patients who underwent secondary repair of obstetric anal sphincter injuries at the colorectal surgery unit of a tertiary care center between February 2015 and December 2017.

Results:

All patients with solid stool incontinence were fully recovered at postoperative month 3. The Wexner incontinence score was significantly improved (decreased from 14.12 [range: 8-20] to 2.28 [range: 1-4]). The complication rate was 85.7% (wound infection, abscess, hematoma, detachment).

Conclusion:

Combined repair of anal sphinchters, perineal body, superficial transverse perineal muscles, and bulbospongious muscles, which contribute to anal continence, may improve surgical outcomes in patients with obstetric anal sphincter injuries.

Safety and efficacy of extending a previous endoscopic sphincterotomy for the treatment of retained or recurrent common bile duct stones

Background:

The aim of the study was to evaluate the safety and efficacy of extending a previous endoscopic sphincterotomy (ES) in patients with retained or recurrent common bile duct (CBD) stones.

Methods:

Between 2001 and 2013, extension of a previous ES, for known or suspected CBD stones, was performed in 118 patients (m/f, 53/65) with a median age of 74 (range: 31-91) years (group A). During the same period, ES was performed in 1064 patients with suspected or known choledocholithiasis (group B). The efficacy and complications of the extension (group A) were analyzed and a comparison was made between groups regarding complications.

Results:

Bile duct cannulation was straightforward in all patients in group A, while it was considered difficult in 49% of patients in group B. Complete clearance was achieved in 76/97 patients (78%) with CBD stones, after a mean of 1.18 attempts per patient. Mechanical lithotripsy was required in 10% of patients. After extension, immediate bleeding occurred in 24 patients (20%), which stopped spontaneously in 9 (37%) and endoscopic hemostasis was required in the remainder. Complications were more frequent in group B (5.3% vs. 0.8%, P=0.031), but there was no significant difference for any individual complication. Immediate bleeding was more common in group B (29% vs. 20%, P=0.035), but there was no difference in clinical bleeding.

Conclusion:

Extension of a previous ES seems to be a simple, effective and safe technique, allowing stone clearance in nearly 80% of patients; it is thus recommended in patients with CBD stones after ES.

Faecal incontinence in patients with a sphincter defect: comparison of sphincteroplasty and sacral nerve stimulation

AIM

Sphincteroplasty (SP) is used to treat faecal incontinence (FI) in patients with a sphincter defect. Although sacral nerve stimulation (SNS) is used in patients, its outcome in patients with a sphincter defect has not been definitively evaluated. We compared the results of SP and SNS for FI associated with a sphincter defect.

METHOD

Patients treated by SNS or SP for FI with an associated sphincter defect were retrospectively identified from an Institutional Review Board approved prospective database. Patients with ultrasound evidence of a sphincter defect were matched by age, gender and body mass index. The main outcome measure was change in the Cleveland Clinic Florida Faecal Incontinence Score (CCF-FIS).

RESULTS

Twenty-six female patients with a sphincter defect were included in the study. The 13 patients in each group were similar for age, body mass index, initial CCF-FIS and the duration of follow-up. No differences were observed in parity (P = 1.00), the rate of concomitant urinary incontinence (P = 0.62) or early postoperative complications. Within-group analysis showed a significant reduction of the CCF-FIS among patients having SNS (15.9-8.4; P = 0.003) but not SP (16.9-12.9; P = 0.078). There was a trend towards a more significant improvement in CCF-FIS in the SNS than in the SP group (post-treatment CCF-FIS 8.4 vs 12.9, P = 0.06). Net improvement in CCF-FIS was not significantly different between the groups (P = 0.06).

CONCLUSION

Significant improvement in CCF-FIS was observed in patients treated with SNS but not SP patients. A trend towards better results was seen with SNS.

Current surgical strategies to treat fecal incontinence

Fecal incontinence is a devastating condition, vastly under-reported, and may affect up to 18% of the population. While conservative management may be efficacious in a large portion of patients, those who are refractory will likely benefit from appropriate surgical intervention. There are a wide variety of surgical approaches to fecal incontinence management, and knowledge and experience are crucial to choosing the appropriate procedure and maximizing functional outcome while minimizing risk. In this article, we provide a comprehensive description of surgical options for fecal incontinence to help the clinician identify an appropriate intervention.

Obstetrical Anal Sphincter Injuries (OASIS): Prevention, Recognition, and Repair

OBJECTIVE

To review the evidence relating to obstetrical anal sphincter injuries (OASIS) with respect to diagnosis, repair techniques and outcomes. To formulate recommendations as to patient counselling regarding route of delivery for subsequent pregnancy after OASIS.

OPTIONS

Obstetrical care providers caring for women with OASIS have the option of repairing the anal sphincter using end-to-end or overlapping techniques. They may also be involved in counselling women with prior OASIS regarding the route of delivery for future pregnancies.

OUTCOMES

The outcome measured is anal continence following primary OASIS repair and after subsequent childbirth.

EVIDENCE

Published literature was retrieved through searches of Medline, EMBASE, and The Cochrane Library in May 2011 using appropriate controlled vocabulary (e.g., anal canal, obstetrics, obstetric labour complication, pregnancy complication, treatment outcome, surgery, quality of life) and key words (obstetrical anal sphincter injur*, anus sphincter, anus injury, delivery, obstetrical care, surgery, suturing method, overlap, end-to-end, feces incontinence). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational. There were no date or language restrictions. Searches were updated on a regular basis and incorporated in the guideline to September 2014. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies.

VALUES

The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1).

BENEFITS, HARMS, AND COSTS

Benefits from implementation of these guidelines include: improved diagnosis of OASIS, optimal functional outcomes following repair, and evidence-based counselling of women for future childbirth.

Delorme's operation plus sphincteroplasty for complete rectal prolapse associated with traumatic fecal incontinence

Rectal prolapse associated with traumatic fecal incontinence is a rare clinical combination. This study was designed to assess Delorme's operation with sphincteroplasty as a surgical management of this combination in terms of recurrence and improvement of fecal incontinence. In this prospective study, we enrolled patients suffering from short, full-thickness rectal prolapse associated with traumatic fecal incontinence who had been admitted to Alexandria Main University Hospital during the period of May 2010–January 2013. Preoperative data including cause of trauma, duration of symptoms, results of anal manometry, and degree of fecal incontinence using Wexner score were collected from all patients. Delorme's procedure with overlap sphincteroplasty was done in all patients. Recurrence of prolapse and improvement of fecal incontinence were assessed after 1, 3, 6 and 12 months. The study included 13 patients aged (32±8.7) years, 9 females and 4 males. Cause of sphincteric injury included previous anal surgery in 7 patients and normal labor in 6 patients. Duration between sphincteric injury and operation was (8.08±2.47) months. Preoperative Wexner's mean score was 16.07±3.4. Early postoperative complications included superficial wound infection (69.2%), minor wound dehiscence (61.5%), and postoperative bleeding (7.6%). Recurrence was detected in 1 patient at 6 month follow-up. Wexner's score showed significant improvement for all patients after 6 months (4.00±2.04). In conclusion, combination of Delorme's procedure and sphincteroplasty for treatment of patients with short complete rectal prolapse associated with traumatic fecal incontinence is a safe, effective surgical management with satisfactory results regarding anatomical and functional outcomes.

Endoscopic sphincterotomy with sphincteroplasty for the management of choledocholithiasis: a single-centre experience

BACKGROUND

Balloon dilatation of the ampulla at endoscopic retrograde cholangiopancreatography (ERCP) is increasingly utilized in the management of large bile duct stones. The aim of this study was to review and compare the outcomes of using endoscopic sphincterotomy with endoscopic balloon dilatation (sphincteroplasty) in a combined approach as a single-stage (immediate) or a two-stage procedure (delayed).

METHODS

A retrospective review of medical records for all patients undergoing ERCP and balloon dilatation for choledocholithiasis between January 2010 and December 2012 was undertaken. Outcomes measured included patient demographics, stone size, degree of dilatation performed, success of stone extraction, number of procedures required for duct clearance and procedure-related complications.

RESULTS

One hundred and thirty-six ERCPs were performed with balloon sphincteroplasty. One hundred and four had a previous sphincterotomy with a delayed balloon dilatation and 32 had sphincterotomy with immediate dilatation. The overall clearance rate of the common bile duct for immediate and delayed groups was 93% (28/30) and 93% (81/87), respectively. Bile duct clearance after the first procedure was achieved in 70% (21/30) of patients in the immediate group and 74% (64/87) in the delayed group. There were six complications in the delayed group and four in the immediate group. The most frequently used balloon size was 10 mm for both groups with mean sizes of 10.34 (2.93) and 11.73 (2.87) in the immediate and delayed groups, respectively.

CONCLUSION

Our study suggests that use of a combined approach is safe and effective and may provide benefits over using endoscopic balloon dilatation or endoscopic sphincterotomy alone in the treatment of choledocholithiasis.

Endoscopic large balloon sphincteroplasty is a useful, safe adjunct for difficult to treat choledocholithiasis

BACKGROUND

The aim of this study was to assess the safety and efficacy of large balloon sphincteroplasty when used in conjunction with endoscopic biliary sphincterotomy during endoscopic retrograde cholangiopancreatography (ERCP) for therapy of choledocholithiasis.

METHODS

A retrospective audit of all ERCP's performed for choledocholithiasis between January 2012 and October 2013 at one institution was performed. Procedures that utilized large balloon sphincteroplasty were compared with those underwent standard endoscopic stone extraction. Outcomes including stone clearance rate for the individual procedure type, post-ERCP complications and need for surgical exploration of the bile duct were documented.

RESULTS

A total of 346 procedures on 306 patients that met the inclusion criteria were identified. Fifty-four (15.6%) procedures included large balloon sphincteroplasty and were compared with 292 (84.4%) procedures that used standard balloon extraction techniques. Despite those patients in the large balloon sphincteroplasty group having a higher rate of previous ERCP (33.3% versus 19.5%, P = 0.031) and a larger proportion of patients with stones greater than 10 mm (40.3% versus 11.3%, P < 0.001), the overall initial clearance rate was similar at 83%. Ultimately, only 14 out of 306 (4.6%) of all patients required surgical intervention. There was no significant difference in the rate of post-ERCP pancreatitis between the two groups (5.6% versus 3.8%, P = 0.466).

CONCLUSION

Large balloon sphincteroplasty of the sphincter of Oddi is a safe and effective adjunct to endoscopic biliary sphincterotomy in difficult to treat choledocholithiasis. The current study demonstrated large balloon sphincteroplasty did not result in more complications despite a tendency to being used for larger stones.

What is the best option for failed sphincter repair?

AIM

This study aimed to evaluate the outcome of various procedures for patients with fecal incontinence following failed sphincteroplasty.

METHOD

Patients who underwent surgery for failed sphincteroplasty from January 2000 to June 2011 [corrected] were identified. They were assessed using the Fecal Incontinence Quality of Life (FIQoL) scale and the Cleveland Clinic Florida-Wexner Fecal Incontinence Score (CCFFIS).

RESULTS

Fifty-nine patients [97% females; median age 52 (25-81) years] were identified. They underwent either repeat sphincteroplasty (RS; n = 33), artificial bowel sphincter (ABS; n = 11) or sacral nerve stimulation (SNS; n = 15). The median follow-up was 31 (3-138) months. The RS group had a significantly wider external sphincter defect and had undergone fewer previous sphincteroplasties. The most common complication was infection. The incidence of complications was significantly higher after ABS (73%) compared with RS (24%) and SNS (33%) (P = 0.01). Seventeen (29%) patients required re-operation for complications or failure, with a lower rate in the RS group (P = 0.004). There was no difference in the rates of device removal after ABS or SNS. Ten (17%) patients underwent further surgery or re-implantation of the device with no difference between the groups. At follow-up, five (45%) ABS and 10 (67%) SNS patients retained a functioning device (P = 0.4). The mean postoperative CCFFIS decreased from 17.5 to 11.5 in the RS group, from 18.7 to 8.6 in the ABS group, and from 17.6 to 9.1 in the SNS group (P ≤ 0.02 for all). There were no differences in the improvement of CCFFIS or FIQoL scores among groups.

CONCLUSION

RS, ABS and SNS are associated with similar improvements in continence after failed sphincteroplasty. Due to increased complications and re-operation with ABS and SNS, RS may be the first step in managing these patients.

Sphincteroplasty for anal incontinence

Sphincteroplasty (SP) is the operation most frequently performed in patients suffering from moderate-to-severe anal incontinence (AI) who do not respond to conservative treatment. Other costly surgeries, such as artificial bowel sphincter (ABS) and electro-stimulated graciloplasty, have been more or less abandoned due to their high morbidity rate. Minimally invasive procedures are widely used, such as sacral neuromodulation and injection of bulking agents, but both are costly and the latter may cure only mild incontinence. The early outcome of SP is usually good if the sphincters are not markedly denervated, but its effect diminishes over time. SP is more often performed for post-traumatic than for idiopathic AI. It may also be associated to the Altemeier procedure, aimed at reducing the recurrence rate of rectal prolapse, and may be useful when AI is due either to injury to the sphincter, or to a narrowed rectum following the procedure for prolapse and haemorrhoids (PPH) and stapled transanal rectal resection (STARR). The outcome of SP is likely to be improved with biological meshes and post-operative pelvic floor rehabilitation. SP is more effective in males than in multiparous women, whose sphincters are often denervated, and its post-operative morbidity is low. In conclusion, SP, being both low-cost and safe, remains a good option in the treatment of selected patients with AI.

Fecal incontinence

Fecal incontinence is a devastating problem for those afflicted. It can lead to embarrassment and social isolation. Treating the problem begins with a thorough history and physical examination. Further testing (such as anal physiology testing or anal endosonography) depends on the examination and treatment plan. Conservative medical therapies (such as dietary manipulation, medication to slow the stool, and biofeedback) are usually tried first. Surgery includes sphincter repair, SECCA, artificial bowel sphincter, and stoma. New therapies continue to evolve with the intention of further improving quality of life for these afflicted patients.

The sphincter of Oddi and acute pancreatitis--revisited

BACKGROUND

One of the rare causes of recurrent acute pancreatitis is sphincter of Oddi dysfunction. This condition is objectively diagnosed by manometry of the sphincter of Oddi. An abnormally elevated sphincter of Oddi basal pressure has been shown to predict patients who have a successful outcome after transduodenal sphincteroplasty and pancreatic duct septoplasty.

METHODS

Forty-nine patients presenting with recurrent pancreatitis and who had manometric stenosis of the sphincter of Oddi were treated by transduodenal division of the sphincter of Oddi. Clinical follow-up was conducted over a minimum of 2 years.

RESULTS

In all, 43 patients were either cured or improved. None of these patients had any further episodes of pancreatitis. Three of these patients developed recurrent symptoms and were noted to have restenosis of the sphincter of Oddi. They were treated by insertion of an endoscopic stent into the pancreatic duct.

CONCLUSION

The results from this series of patients re-affirm the efficacy of transduodenal sphincteroplasty and septoplasty for treatment of sphincter of Oddi stenosis in patients presenting with recurrent acute pancreatitis.
