Laparoscopic-assisted anorectoplasty for anorectal malformation with rectobulbar fistula: A two-center comparative study with posterior sagittal anorectoplasty. Medicine (Baltimore) 2023; 102:e35825. [PMID: 37986398 PMCID: PMC10659725 DOI: 10.1097/md.0000000000035825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Revised: 10/05/2023] [Accepted: 10/06/2023] [Indexed: 11/22/2023] Open
Abstract
Due to the controversy on the feasibility of laparoscopic-assisted anorectoplasty (LAARP) for the treatment of the anorectal malformation (ARM) with rectobulbar fistula (RBF), this study aimed to compare the outcomes of LAARP and posterior sagittal anorectoplasty (PSARP) for ARM with RBF. Demographic data, postoperative complications, and bowel function of RBF patients who underwent LAARP and PSARP at 2 medical centers from 2016-2018 were retrospectively reviewed. Eighty-eight children with RBF were enrolled, including 43 in the LAARP group and 45 in the PSARP group. There were no significant differences in the sacral ratio (P = .222) or sacral agenesis (P = .374). Thirty-seven and 38 patients in the LAARP and PSARP groups were followed up for a median of 4.14 years. The postoperative complications were comparable between the groups (P = .624), with no cases of urethral diverticulum. The urination of all cases was normal and no evidence of cyst formation was found on MCU or MRI during the follow-up period. The incidence of rectal prolapse was similar between the 2 groups (9.3% vs 17.8%, P = .247). The groups had equivalent Bowel Function Score (15.29 ± 2.36 vs 15.58 ± 2.88, P = .645), but the LAARP group had better voluntary bowel movement (94.6% vs 84.2%, P = .148) by Krickenbeck classification. The intermediate-term outcomes of LAARP show that the urethral diverticulum was rare by the intraluminal incision of the fistular and the bowel function was comparable to that of PSARP in ARM with rectobulbar fistula. However, LAARP was associated with smaller perineal wounds.

Photodiagnosis Photodyn Ther 2023; 42:103335. [PMID: 36781006 DOI: 10.1016/j.pdpdt.2023.103335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 02/03/2023] [Accepted: 02/08/2023] [Indexed: 02/13/2023]
Abstract
BACKGROUND Rectourethral fistulae (RUF) are the most prevalent type of anorectal malformations in boys, with various surgical treatment methods investigated in recent years. Currently, research is focused on preventing urethral damage or urethral diverticulum formation caused by imprecise dissection during the laparoscopically assisted anorectal pull-through (LAARP) technique. This study aimed to determine the efficacy of indocyanine green (ICG) fluorescence imaging to improve the localization and separation of the RUF during laparoscopic surgery. METHODS ICG was intrarectally injected through a pre-inserted gastric tube at the distal enterostomy port to locate the fistula. This retrospective analysis included children with RUF who were treated surgically with ICG fluorescence imaging localization-assisted LAARP between January and June 2022. We investigated the patient demographics, perioperative conditions, and subsequent follow-up results. RESULTS Four patients underwent ICG-assisted LAARP. Their median age was 80 days (range, 63-120) and the median duration of each procedure was 145 min (range, 120-165). Postoperatively, the duration of catheter retention and hospital stay was eight days. The children's prognosis was based on the follow-up outcomes of gastrointestinal, urinary tract function, and imaging examination. None of the included patients was diagnosed with urinary diverticulum, urinary tract injury, anal stricture, or rectal prolapse. CONCLUSIONS Injection of ICG at the end of the rectum during LAARP surgery is a feasible adjunct for locating the RUF, providing a greater degree of accuracy for laparoscopic separation and resection of fistulae, thereby decreasing the risk of urological complications.

Abstract
BACKGROUND A posterior urethral diverticulum (PUD) is a serious postoperative complication after anorectal malformation correction. Complete resection is technical demanding because of limited retrourethral working space deep in the pelvis. OBJECTIVE We pioneered the single-incision laparoscopic approach for PUD excision and evaluated the efficacy. DESIGN, SETTING, AND PARTICIPANTS Twenty-six PUD patients undergoing redo surgeries between June 2011 and June 2021 were reviewed. SURGICAL PROCEDURE A series of transabdominal retraction sutures were placed through the PUD to facilitate dissection. The contents were evacuated to create a working space. Distal PUD dissection was carried along the submucosal layer to prevent injury of the urethra/pelvic nerve complex. The rectal mucosa was peeled off from the junction site for complete PUD excision. The muscular cuff of the distal rectum was then oversewn. MEASUREMENTS Operative time, postoperative recovery, and complications were assessed. RESULTS AND LIMITATIONS The mean age of redo surgery was 2.46 yr. The average operative duration was 2.35 h. The mean postoperative hospital stay, resumption of full diet, and bowel movement were 10.23, 2.15, and 1.54 d, respectively. The median follow-up period was 46 mo (12-132 mo). No remnant of PUD, recurrent fistula, or urinary leak was detected. None of the patients had difficulty in urination, urinary dribbling, urinary tract infection, constipation, or soiling. All patients retained morning erection, and two postpubertal patients had ejaculations. CONCLUSIONS Our single-incision laparoscopic redo surgery provides an effective approach for PUD excision. It minimizes complications. It also preserves urinary and bowel continence and sexual function. PATIENT SUMMARY Complete resection of a posterior urethral diverticulum (PUD) in anorectal malformation is technically demanding because of limited retrourethral working space in the deep pelvis. The outcomes of single-incision laparoscopic PUD excision were satisfactory.

Abstract
The etiology of anorectal malformations (ARM) is complicated because of the spectrum of anomalies seen clinically, many of which are isolated and seemingly unique. Recent studies suggest that ARMs result from abnormal cloacal membrane (CM) development that contributes to disrupt normal local muscle and nerve development. If CM maldevelopment is severe, the rectal pouch lies above the pelvic floor, resulting in asymmetric and/or deviated musculature, so a midline incision is likely to cause trauma or be detrimental. Autonomic nerve plexuses can be associated with a fistula tract in ARMs and are also at risk for damage during surgery and contribute to genitourinary complications. Understanding the anatomy and development of the perineum is crucial for treating the broad spectrum of anomalies associated with ARMs and may assist in predicting/managing other related morbidity.

Abstract
PURPOSE To report the sequelae of and preventive strategies for selected lower urinary tract (LUT) complications, i.e., posterior urethral diverticulum (PUD), intraoperative LUT injuries, postoperative dysuria, and fistula recurrence in male imperforate anus (IA) with rectourethral/rectovesical (RU/RV) fistula after laparoscopy-assisted anorectoplasty (LAARP) or posterior sagittal anorectoplasty (PSARP). METHODS 153 boys with IA and RU/RV fistula treated 1986-2019 by LAARP (n = 56) or PSARP (n = 97) at two unrelated institutes were studied retrospectively. RESULTS After mean follow-up of 17.0 years (range: 36.5 days-32.0 years), the overall incidences of LUT complications were: LAARP (6/56; 10.7%); PSARP (7/97; 7.2%); p = 0.55, comprising PUD: LAARP (n = 5), PSARP (n = 0); p = 0.006; injuries: LAARP (n = 0), PSARP (n = 5); p = 0.16; dysuria: LAARP (n = 1), PSARP (n = 1); p>0.999; and recurrence: LAARP (n = 0), PSARP (n = 1); p>0.999. Mean onset of PUD was 5.1 years (range: 1.0-15.1 years). TREATMENT PUD: surgery (n = 2/5), conservative (n = 3/5); injuries: intraoperative repair (n = 5/5); dysuria: conservative (n = 2/2), and recurrence: redo PSARP (n = 1/1). CONCLUSIONS Strategies devised to improve dissection accuracy resolved the specific technical issues causing LUT complications (remnant RU fistula dissection in LAARP and blind posterior access in PSARP). Currently, the incidence of new cases of PUD and LUT injuries is zero. LEVEL OF EVIDENCE Level III.

A novel combined enteroscopy and laparoscopy approach to prevent urethral complications in management of rectourethral fistula. Surg Endosc 2021; 35:1921-1926. [PMID: 33523272 DOI: 10.1007/s00464-020-08268-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Accepted: 12/22/2020] [Indexed: 10/22/2022]
Abstract
BACKGROUND For the last 20 years, laparoscopy management of anorectal malformations (ARM) has been challenged due to the development of postoperative urethral diverticulum or injury caused by the imprecise transection of rectourethral fistulae, particularly rectobulbar fistulae situated deep in the pelvis. We have developed a combined approach of enteroscopy and laparoscopy for intraluminal incision of a rectourethral fistula. METHODS We retrospectively reviewed 47 ARM patients who underwent surgical corrections using the combined approach between January 2019 and June 2020. Early postoperative and subsequent follow-up results were evaluated. RESULTS The median follow-up period was 12 months. The average age at surgery was 3.18 ± 0.64 months. The mean operative time of a single-incision laparoscopic-assisted anorectoplasty (SILAARP) was 1.19 ± 0.29 h. The time for intraluminal incision of the fistula was shortened from 14 to 2 min. No patients underwent a conversion. The average postoperative hospital stay, time to full feeds and placement of an anal tube were 10 days, 1 day, and 5 days, respectively. No urethral diverticulum, urinary injury, wound infection, rectal retraction, anal stenosis or rectal prolapse was encountered in the cohort. CONCLUSIONS The combined enteroscopy and laparoscopy approach offers precise management of rectourethral fistulae. It could effectively obviate urethral complications, eliminating the obstacles of laparoscopy application in the management of ARMs.

Abstract
AIM It has long been considered surgical dogma that the length of the shared common wall (CW) between a fistula and the urethra in males with anorectal malformation (ARM) and rectourethral bulbar fistula (RUBF) is considerably longer than in males with ARM and rectourethral prostatic fistula (RUPF). This belief has led surgeons who perform laparoscopic-assisted anorectoplasty (LAARP) for RUPF to avoid LAARP for RUBF for risk of potential injury to the urethra or incomplete removal of the fistula. In this study, we compared CW between RUBF and RUPF using distal colostography (DCG) and direct intraoperative measurements. METHODS DCG of rectourethral fistula patients (n = 63; RUBF: n = 44; RUPF: n = 19) were used to measure CW retrospectively. Results were expressed as a ratio of the height of L4; i.e., CW:L4. If less than 0.7, the CW was classified as being "short"; if 0.71-1.4, as being "medium"; and if greater than 1.41, as being "long". CW that could not be measured was classified as indeterminate. 24 of these patients also had CW measured intraoperatively during LAARP as previously described. The results obtained using both techniques were also compared. RESULTS Surprisingly, CW:L4 in RUBF patients was short in 47.7%, medium in 27.3%, long in 20.5%, and indeterminate in 4.5% on DCG, equivalent to mean lengths of 7 mm, 8.5 mm, and 10.3 mm obtained using direct intraoperative measurement for short, medium, and long CW:L4 categories, respectively. CW:L4 in RUPF was short in 73.6%, medium in 10.5%, and long in 5.2% on DCG, while mean intraoperative measurements were 5 mm, 7 mm, and 10 mm, respectively. Differences in CW measured intraoperatively were not significantly different between RUBF and RUPF (p = NS). CONCLUSION From our findings, 47.7% of CWs in RUBF were short using two independent methods, with only 20.5% being long. Thus, LAARP should be considered actively for treating selected RUBF cases and not be excluded on the basis of CW length.

Abstract
Aim: This study aimed to compare the surgical outcomes of patients with the intermediate-type imperforate anus who underwent laparoscopically assisted anorectoplasty (LAARP; L group) with those of patients who underwent sacroperineal anorectoplasty (S group). Materials and Methods: The medical records of patients with intermediate-type imperforate anus at a single institution between April 1983 and April 2017 were retrospectively reviewed. Fecal continence was evaluated using the clinical assessment score for fecal continence developed by the Japanese Study Group of Anorectal Anomalies (maximum score, 8). Results: Twelve cases (rectobulbar urethral fistula, 7; anal agenesis without fistula, 4; and rectovaginal fistula, 1) were included in the L group versus 14 cases (rectobulbar urethral fistula, 11, and anal agenesis without fistula, 3) in the S group. Age and body weight at the time of surgery and rate of associated anomalies did not differ significantly between the two groups. The total scores for fecal continence 3, 5, and 7 years after anorectoplasty were 4, 5, and 4 points in the L group and 4, 5, and 6 points in the S group, respectively, showing no significant intergroup differences. Mucosal prolapse occurred in 50% of the L group and 29% of the S group (P = .42), but failed rectocutaneous anastomosis and anal stenosis were not identified in either group. Conclusions: Postoperative fecal continence and the incidence of complications after LAARP were comparable with those after sacroperineal anorectoplasty in patients with intermediate-type imperforate anus.

Abstract
Rectourethral fistula is an uncommon but devastating condition resulting from surgery, radiation, trauma, inflammation, or occasionally anorectal anomaly. Because of involving the urinary and the digestive system, surgical repair can be challenging. More than 40 different surgical approaches were described in the literature. However, no standardized management exists due to the rarity and complexity of the problem. Spontaneous closure of fistula is rare and most cases need reconstructive procedures. Appropriate preoperative assessment is crucial for the decision of operation time and method. Gradually accumulating evidence indicates surgeons should take fistula size, tissue health and vascularity associated with radiation or infection, urethral stricture, and bladder neck sclerosis into consideration and make a proper treatment plan according to the features of various approaches. Accurate preoperative evaluation and proper approach selection would increase success rates. Multiple surgical team corporation, including colorectal, urological and plastic surgeons, would optimize the outcomes.

Is measuring the residual rectourethral fistula during laparoscopically assisted anorectal pull-through for male high/intermediate type imperforate anus beneficial? Mid-term follow-up. J Pediatr Surg 2017; 52:1994-1996.

Abstract
BACKGROUND/PURPOSE We evaluated routine intraoperative residual rectourethral fistula measurement (IRRFM) in 20 consecutive male imperforate anus with recto-bulbar (RB; n=12) or recto-prostatic (RP; n=8) fistula during laparoscopically assisted anorectal pull-through (LAARP) for preventing incomplete fistula excision (IFE) on mid-term follow-up. METHODS Twenty consecutive LAARP performed at a mean age of 10months (range: 3-30) followed-up for a mean of 4.8years (range: 1.5-9) were reviewed. IRRFM involves using a calibrated catheter and a cystoscope to measure the distance between where dissection was ceased at the rectal end and the urethral orifice (Figure). Dissection and IRRFM were repeated until the fistula was <5mm, then tied, and divided. Magnetic resonance imaging (MRI) and pelvic ultrasonography were used to exclude IFE and cyst formation. RESULTS Residual fistula was 4-18mm on initial IRRFM. Unless measured, dissection cannot proceed to <5mm safely with poentical for urethral injury or IFE. With experience, initial IRRFM were shorter, especially in RP (Table 1). Before the IRRFM era, our incidence of cysts was 2/11 (18%), but here we found no evidence of cyst formation on MRI, no dysuria, and no urinary tract infections. CONCLUSIONS Mid-term review demonstrates that IFE can be prevented successfully by IRRFM during LAARP. LEVEL OF EVIDENCE Case Series with no Comparison Group, Level IV.

Abstract
Anorectal malformations are an important group of congenital anomalies that vary widely in their anatomical characteristics and complexity. Understanding the long-term functional outcomes after modern treatments, and how these compare to the general population, are essential for ensuring that patients receive optimal, evidence-based care. With increasing appreciation of the wider impact of the illness on patients and their families, minimizing social disability from fecal incontinence and enabling normal social integration from the outset are key management concerns. This review summarizes the current knowledge on the functional outcomes by type of malformation, reflecting on the literature, and our institutional experience over a follow-up period of nearly 30 years.

Abstract
Anorectal malformations are uncommon but complex congenital anomalies that require an individualised strategy of care for each step of the treatment process. These steps, which include preoperative evaluation, operative reconstruction, and postoperative care, are each unique and vitally important to overall patient outcomes. In this Review, we discuss some of the pivotal decisions that should be made at each stage of patient care. Through this process, we highlight some of the more controversial aspects of caring for patients with anorectal malformation and offer insights into various management philosophies.

Abstract
PURPOSE Laparoscopically assisted anorectoplasty (LAARP) was compared to posterior sagittal anorectoplasty (PSARP) in the treatment of male imperforate anus associated with either recto-prostatic fistula (RPF) or recto-bulbar fistula (RBF). METHOD 19 RPF patients (12 treated by LAARP and 7 by PSARP) and 26 RBF patients (14 treated by LAARP and 12 by PSARP) between 1995 and 2014 were retrospectively assessed using a fecal continence evaluation questionnaire (FCE) (with a maximum score of 10), an FCE score coefficient variation, as well patients' MRI scores, anorectal angle values (AA), and incidence of postoperative complications. Statistical significance was determined at p < 0.05. RESULTS Both groups were similar in mean age and mean weight at repair, as well as sacral status. Postoperatively, mean MRI scores, mean AA, and biochemistry were also similar (p = NS). All cases treated with LAARP showed consistently higher and less variable FCES values, fewer wound infection incidence, but greater rectal mucosal prolapse unrelated with sacrum status. Significantly lower doses of postoperative analgesia were needed in all LAARP cases (p < 0.05). CONCLUSION Technical outcomes appear to be similar based on imaging studies, but FCES-assessed functional outcomes appear to favor LAARP for treatment of both RPF and RBF.

Abstract
Seventeen years have passed since the first description of the laparoscopic approach for anorectal malformation and approximately 68 articles have been published on the subject. In this review article, we aim to describe the advantages as well as the indications and contraindications of this approach when dealing with each specific type of anorectal malformation, according to what has been described in the literature and to our own experience. The ideal and undisputable indication for laparoscopy remains for cases in which the abdomen needs to be entered to repair the malformation. Only 10% of male patients with anorectal malformation are born with a recto-bladder neck fistula that requires an abdominal approach, this represents an ideal indication for laparoscopy. In females, only the complex cloacae with a common channel length greater than 3 cm are the ones that require a laparotomy; they represent about 30% of the cloacae. However, the repair of this type of cloacae also requires sophisticated and technically demanding maneuvers that have never been done laparoscopically. In cases of recto-urethral prostatic fistulas the malformation can be repaired either way: laparoscopically or posterior sagitally. In all other malformations: recto-perineal fistula, recto-urethral bulbar fistula, anorectal malformation without fistula, rectal atresia, recto-vestibular fistula; no justification for laparoscopy could be found; and in some cases, laparoscopy is contraindicated. In the published reports, there is no evidence supporting the idea that laparoscopic repair results in better functional results when compared with non-laparoscopic operation; there is a tendency to omit information relevant to bowel control such as the characteristics of the sacrum and the presence or absence of tethered cord; and most authors do not compare results between comparable malformations.

Abstract
PURPOSE All reports comparing laparoscopy-assisted anorectoplasty (LAARP) with posterior sagittal anorectoplasty (PSARP) in male high-type imperforate anus include a mix of recto-vesical, recto-prostatic, recto-bulbar, and absent fistula cases without focusing on recto-bulbar fistula (RBF), the most challenging type to treat laparoscopically. We compared LAARP with PSARP for treating only RBF. METHOD We used our fecal continence evaluation questionnaire (FCE; maximum score=10), scoring of magnetic resonance imaging (MRI) findings (MRI scores), and the angle between the rectum and the anal canal (RAA) to assess 20 RBF cases (LAARP=12, PSARP=8) treated from 2000 to 2013 prospectively. RESULTS Mean ages at surgery, MRI scores, mean RAA, and duration of raised C-reactive protein (6.6 vs. 6.7days; p=NS) were similar. In all cases, postoperative MRI showed no residual fistula and normal urination. LAARP had consistently higher FCE (7.9 vs. 7.8 at 3years; 8.6 vs. 8.3 at 5years; 8.9 vs 8.6 at 7years; p=NS, respectively), less wound infections (0 vs. 37.5%; p<0.05), higher incidence of rectal mucosal prolapse (50.0 vs. 0%; p<0.05), and required less analgesia (p<0.05). CONCLUSION Although LAARP and PSARP are comparable for treating RBF, LAARP is associated with less wound infections and higher incidence of rectal mucosal prolapse.
