Natural Orifice Transanal Endoscopic Rectopexy for Complete Rectal Prolapse: Prospective Evolution of a New Technique and Short-term Outcomes.

BACKGROUND: Endoluminal surgery for the management of rectal prolapse remains largely experimental. OBJECTIVE: To evaluate the evolution and short-term outcomes of a new endoluminal technique for the management of complete rectal prolapse. DESIGN: This was a prospective study. SETTINGS: This study was conducted at a single tertiary care teaching center. PATIENTS: A total of 29 patients were included. The first 12 patients underwent the procedure with our initial technique, and the last 17 patients were subjected to the new modified procedure. The follow-up duration was 3 years for the older technique and 26 months for the newer technique. INTERVENTION: This technique involves: 1) ventral "suture" rectopexy: rectum is fixed anteriorly to the anterior abdominal wall using percutaneously placed sutures. 2) Posterior rectum is fixed to the sacral promontory using tackers through a submucosal tunnel. MAIN OUTCOME MEASURES: Safety, recurrence, functional outcomes, morbidity, and mortality were the main outcome measures. RESULTS: There were improvements in constipation and incontinence scores, anal manometric pressures, anorectal angle, anorectal descent, and quality of life postoperatively in both groups. In patients undergoing the modified procedure, there was a significant decrease in duration of surgery (220 ± 48.89 vs 110 ± 12.51 min), shortened hospital stay (4.6 ± 1.71 vs 2.6 ± 0.65 d), decreased recurrence (25% vs 5.8%), and complications (surgical-site infection and retrorectal abscess). LIMITATIONS: Short follow-up, small sample size, and single-center study were the limitations. CONCLUSION: This is a novel endoluminal technique for treating rectal prolapse obviating perirectal dissection, abdominal incisions, or a mesh. This can now be performed under complete endoscopic and fluoroscopic vision. It avoids general anesthesia and therefore can be an alternative for patients with comorbid conditions in whom the standard abdominal procedure may not be well tolerated. Larger randomized multicentric studies with longer follow-ups are warranted. See Video Abstract at http://links.lww.com/DCR/C59. RECTOPEXIA ENDOSCPICA TRANSANAL POR ORIFICIO NATURAL PARA EL PROLAPSO RECTAL COMPLETO EVOLUCIN PROSPECTIVA DE UNA NUEVA TCNICA Y RESULTADOS A CORTO PLAZO: ANTECEDENTES:La cirugía endoluminal para el tratamiento del prolapso rectal ha permanecido en gran parte experimental.OBJETIVO:Este estudio tiene como objetivo evaluar la evolución y los resultados a corto plazo de una nueva técnica endoluminal para el manejo del prolapso rectal completo.DISEÑO:Estudio prospectivo.ÁMBITOS:Único centro docente de tercer nivel de atención.PACIENTES:Se incluyeron un total de 29 pacientes (19 hombres y 10 mujeres) con prolapso rectal completo. Los primeros 12 pacientes fueron sometidos al procedimiento con nuestra técnica anteriormente descrita y los últimos 17 pacientes fueron sometidos al nuevo procedimiento modificado.

B) El recto posterior se fija al promontorio sacro mediante grapas a través de un túnel submucoso.PRINCIPALES MEDIDAS DE RESULTADO:Seguridad, recurrencia, resultados funcionales, morbilidad y mortalidad.RESULTADOS:Hubo mejorías en las puntuaciones de estreñimiento (ODS) e incontinencia (SMIS), presiones manométricas anales (reposo y contracción), ángulo anorrectal, descenso anorrectal y calidad de vida post operatoria en ambos grupos. En los pacientes sometidos al procedimiento modificado hubo una significativa disminución en la duración de la cirugía (220 + 48,89 vs 110 + 12,51 minutos), acortamiento de la estancia hospitalaria (4,6 + 1,71 vs 2,6 + 0,65 días), disminución de la recurrencia (25% vs 5,8%) y complicaciones (infecciónes del sitio quirúrgico y abscesos retrorrectales).LIMITACIONES:Seguimiento corto, tamaño de muestra pequeña, estudio de un solo centro.CONCLUSIÓNES:La rectopexia endoscópica transanal por orificio natural (NOTER) es una novedosa técnica endoluminal para el tratamiento del prolapso rectal que evita la disección perirrectal, las incisiones abdominales o la fijación de una malla. Este procedimiento puede realizar hoy día bajo visión completa endoscópica y fluoroscópica. Evita la anestesia general y, por lo tanto, puede ser una alternativa para pacientes con condiciones comórbidas donde el procedimiento abdominal estándar puede no ser bien tolerado. Se justifican estudios multicéntricos aleatorios más grandes con un seguimiento más prolongado para validar aún más esta nueva técnica. Consulte Video Resumen en http://links.lww.com/DCR/C59.

Bardet-Biedl Syndrome with Choledochal Cyst: Rare Association with a Novel Variant.

Bardet-Biedl syndrome is an autosomal-recessive ciliopathic disorder affecting multiple organ systems. Characteristic features include progressive retinal dystrophy, obesity, polydactyly hypogonadism, mental retardation, and renal disorders. Other manifestations include congenital heart diseases, hepatic fibrosis, ataxia, and diabetes. Approximately 30% of patients with Biedl-Bardet syndrome (BBS) have hepatobiliary disorders such as periportal fibrosis, nonalcoholic fatty liver disease, and cystic dilation of the bile ducts. The association of BBS with choledochal cysts (CDC) is extremely rare. Here, we report a case of a 14-year-old boy with a novel variant of BBS and associated type IV CDC. The patient was managed surgically with CDC excision and Roux-en-Y hepaticojejunostomy.

Forecasting major impacts of COVID-19 pandemic on country-driven sectors: challenges, lessons, and future roadmap.

The pandemic caused by the coronavirus disease 2019 (COVID-19) has produced a global health calamity that has a profound impact on the way of perceiving the world and everyday lives. This has appeared as the greatest threat of the time for the entire world in terms of its impact on human mortality rate and many other societal fronts or driving forces whose estimations are yet to be known. Therefore, this study focuses on the most crucial sectors that are severely impacted due to the COVID-19 pandemic, in particular reference to India. Considered based on their direct link to a country's overall economy, these sectors include economic and financial, educational, healthcare, industrial, power and energy, oil market, employment, and environment. Based on available data about the pandemic and the above-mentioned sectors, as well as forecasted data about COVID-19 spreading, four inclusive mathematical models, namely-exponential smoothing, linear regression, Holt, and Winters, are used to analyse the gravity of the impacts due to this COVID-19 outbreak which is also graphically visualized. All the models are tested using data such as COVID-19 infection rate, number of daily cases and deaths, GDP of India, and unemployment. Comparing the obtained results, the best prediction model is presented. This study aims to evaluate the impact of this pandemic on country-driven sectors and recommends some strategies to lessen these impacts on a country's economy.

Laparoscopic management of an ileal lipoma presenting with massive gastrointestinal haemorrhage.

Small bowel lipomas are benign submucosal neoplasm composed mainly of mature adipose tissue. Despite their rare occurrence, lipomas are the second most common benign tumour of the small intestine. These tumours are mostly small in size and remain clinically asymptomatic. However, larger lesions tend to be more symptomatic, presenting with complications such as intussusception, bleeding or obstruction. Definitive surgical or endoscopic intervention is indicated in such symptomatic lipomas. Herein, we describe a rare case of ileal lipoma presenting with ileo-ileal intussusception and a life-threatening haemorrhage that was managed by laparoscopic-assisted ileal resection.

Surgical management of cystic duct stump calculi causing post-cholecystectomy syndrome: A prospective study.

Aim: Remnant cystic duct stump calculi are an uncommon but important cause of 'post-cholecystectomy syndrome'. High index of suspicion is needed to diagnose this condition in a symptomatic post-cholecystectomy patient. We present our experience with the surgical management of this condition. Patients and Methods: This prospective study included 19 patients with residual gallstone disease who underwent completion cholecystectomy between August 2016 and October 2021. Investigations included abdominal ultrasound and magnetic resonance cholangiopancreatography. The demographic, clinical, surgical and early post-operative variables of these patients were prospectively maintained and analysed. Results: The study included 14 women and 5 men. The mean age was 42.1 years (range, 14-80 years). The median duration between index surgery and completion cholecystectomy was 36 months (range, 2-178 months) (interquartile range, 105 months). The follow-up duration was 2 months. The initial surgery was open cholecystectomy in 17 and laparoscopic cholecystectomy in 2 patients. All patients with residual stump stone presented with pain, while 10 out of 19 patients complained of dyspepsia. Completion cholecystectomy could be performed laparoscopically in 16 cases, whereas 3 patients underwent open surgery. The mean operative time was 80 min (range, 55-140 min), and the mean blood loss was 100 ml (range, 50-160 ml). The mean hospital stay was 3 days (range, 2-10 days). No post-operative mortality or major morbidity was recorded in any of our patients. Conclusion: Laparoscopic excision of the cystic duct stump is feasible and safe even after previous open cholecystectomy. It is increasingly becoming the treatment of choice where expertise is available.

Tactics, techniques, and challenges in the management of giant choledochal cyst in adolescents and adults: a retrospective cohort study.

BACKGROUND: Choledochal cyst is a rare congenital anomaly manifesting as cystic dilatation of the biliary tree. This study presents our 5-year experience with giant choledochal cyst in adolescents and adults, focusing primarily on its clinical presentation, operative challenges, and pragmatic solutions. METHODS: A retrospective observational study was conducted on 58 adolescent and adult choledochal cyst patients who were managed at a tertiary care hospital. Giant choledochal cyst is defined as cyst with a maximum diameter of ≥ 10 cm. Demographic profile, clinical presentation, and surgical outcome of these patients were analyzed. RESULTS: A total of 12 patients with giant choledochal cyst were managed in our department in a duration of 5 years. The median age of patients with giant choledochal cyst was 20 years (range, 13-30 years) and male to female ratio was 1:2. Giant choledochal cysts were more symptomatic and 8 out of 12 presented with classic triad of abdominal pain, mass, and jaundice. One patient with giant choledochal cyst had metastatic cholangiocarcinoma. Eleven patients underwent surgical cyst excision. Surgery of the giant cyst was challenging and required technical modifications for safe excision. CONCLUSION: Giant choledochal cyst is an unusual entity that is rarely encountered beyond first decade of life. These cysts pose unique surgical challenges and require modification of the standard operative technique.

Corrosive Esophageal Strictures: From Dilatation to Replacement: A Retrospective Cohort Study.

Endoscopic dilatation is the recommended primary therapy for chronic corrosive esophageal strictures (ES), and surgery is reserved for failed dilatation. Through this study, we intend to analyze the efficacy and long-term outcomes of both endoscopic and surgical interventions in corrosive ES. A retrospective cohort analysis of patients with chronic corrosive ES, managed with endoscopic or surgical procedures at a tertiary teaching institute in North India from December 2009 to December 2016, was performed from a prospectively maintained database. The primary outcome measure was the absence of dysphagia following dilatation or surgery. During the study period, 64 patients with ES underwent surgical or endoscopic treatment. Associated gastric strictures and pharyngeal strictures were present in 39 (60%) and 22 patients (28.9%), respectively. The mean age was 28.8 years and mean BMI was 14.2 kg/m2. Acid was the most common corrosive substance. Endoscopic dilatation using Savary-Gilliard (SG) dilators was successful in achieving persistent symptom relief in 46 patients (71.8%) after a total of 358 sessions (mean number of dilatations were 5.2 ± 1.2) of dilatations over 2 years. The dilatation therapy failed in 18 patients (28.1%) including technical failures (15.6%), perforations (3.1%), refractory stricture (1.5%) and recurrent strictures (7.8%). Increasing stricture length (more than 6 cm) was associated with poor outcome of endoscopic dilatation (p < 0.001). Only eleven patients (17%) required esophageal replacement (resection: 0, bypass: 11) for failed dilatations including seven gastric pull-ups and four pharyngo-coloplasty. The stricture rate after surgery was 36.3% (4/11). The median follows up was 32 months. Endoscopic dilatation of corrosive ES is safe and effective therapy and should be the first-line therapy for these patients and surgery should be considered only in patients who have unsuccessful outcome following dilatation therapy.

Composite Antropyloric Valve and Gluteus Maximus Muscle Wrap for Neoanal Reconstruction: Initial Results.

BACKGROUND: Severe fecal incontinence has a significant negative impact on patient well-being. Current surgical methods of total anorectal reconstruction to substitute a colostomy have suboptimal results. A composite graft using antropyloric valve transposition and gracilis wrap has been described with good outcomes. However, this procedure requires extensive training of patients. Gluteus maximus, an accessory muscle for continence, may be better suited for this purpose. OBJECTIVE: The purpose of this study was to evaluate the outcomes of composite antropylorus-gluteus graft for intractable fecal incontinence. DESIGN: Patients underwent a 3-stage procedure: antropyloric transposition with diversion stoma followed by gluteus wrap. Stoma was closed after ensuring the anatomic and functional integrity of the graft. SETTINGS: This study was conducted at a single tertiary care institution. PATIENTS: Patients who were on permanent colostomy for intractable incontinence or would have had one after abdominoperineal resection were included. MAIN OUTCOME MEASURES: Endoultrasonography, MRI, loopogram, saline holding test, anal manometry, St. Mark's fecal incontinence score, and personal interviews were used for measurement. RESULTS: Eleven patients underwent the procedure with a median follow-up of 16 months (range, 13-34 mo). Digital rectal examination revealed a resting tone with a distinct squeeze provided by the composite graft. Radiological imaging confirmed healthy grafts. There was a significant improvement in mean anal manometry values (resting pressure: preoperative = 10.25 mm Hg vs postoperative = 20.45 mm Hg; squeeze pressure: preoperative = 22.63 mm Hg vs postoperative = 105.18 mm Hg) and mean incontinence score postprocedure (preoperative = 22.8 vs postoperative = 8.6). On personal interview, majority of the patients were continent and expressed satisfaction with the procedure. LIMITATIONS: The study was limited by its small sample size with no control group. CONCLUSIONS: Composite graft in patients with intractable fecal incontinence can serve as a viable novel method for total anorectal reconstruction. However, it should only be recommended for a highly select group of individuals in a surveillance setting. Its long-term outcomes remain to be determined as well as its risk versus benefit.

Blumgart's technique of pancreaticojejunostomy: Analysis of safety and outcomes.

BACKGROUND: Blumgart's pancreaticojejunostomy (PJ) has been described with low pancreatic leak rates. This study aimed to evaluate our experience with this technique regarding the pancreatic leak and other perioperative outcomes. METHODS: We performed a single-center retrospective analysis of a cohort of 81 patients who underwent pancreaticoduodenectomy in our department from January 2011 to February 2018. The primary endpoint was the occurrence of a clinically relevant postoperative pancreatic fistula (CR-POPF) and analysis of its risk factors. RESULTS: The CR-POPF rate was 12.3%. Fistula risk score (FRS) was the only significant risk factor for the occurrence of overall POPF in multivariate analysis. However, none of the other factors including FRS was found to be significantly associated with CR-POPF risk. A strong positive correlation was found between the CR-POPF and the incidence of delayed gastric emptying, post-pancreatectomy hemorrhage and increased length of hospital stay. CONCLUSION: Blumgart's technique is a safe technique of pancreatico-enteric anastomosis with low rates of CR-POPF. CR-POPF with this technique is independent of most of the preoperative and intraoperative factors. Therefore, this technique can be used for all types of the pancreas with consistently good results.

Management of post cholecystectomy vascular injuries.

INTRODUCTION: Vasculobiliary and vascular injuries following cholecystectomy are the most serious complications requiring complex surgical management resulting in greater patient morbidity and mortality. METHODOLOGY: The study was performed at a tertiary teaching hospital of North India. Records of patients referred for biliary or vascular injury sustained during cholecystectomy were reviewed retrospectively to identify patients with vascular injury between January 2009 and March 2018. Clinical profile, hospital course and outcome of these patients were analysed. RESULTS: Over nine years, 117 patients were referred for cholecystectomy related complications. Total incidence of vascular injury was 5.1% (6/117). Combined vasculobiliary injury (VBI) occurred in 3.4% (4/117) while isolated vascular injury was present in 1.7% patients (2/117). Most (5/6) patients were operated for uncomplicated gall stone disease. Incidences of portal vein (PV) and right hepatic artery (RHA) injuries were equal (3/6). PV injuries were repaired either during cholecystectomy (1/3) or during re-exploration after damage control packing (2/3). RHA injuries presented as pseudoaneurysm and were managed surgically (2/3) or by coil embolization (1/3). All VBI referrals (4/117) were following open cholecystectomy. In VBI patients, vascular injury was diagnosed intra-operatively in two while it was diagnosed several weeks after cholecystectomy in two others. Biliary injury manifested as bile leak post-operatively in all four of them. Nature of biliary injury could be characterized in only 50% (2/4) patients. Definitive repair of biliary injury was performed in one patient only. There was one mortality in our series. CONCLUSION: Vascular injury is an uncommon complication of cholecystectomy with catastrophic outcome if not managed timely and properly. Adequate surgeon training, keeping the possibility of aberrant vasculobiliary anatomy in all cases, and proper surgical technique is crucial for prevention of such injuries. However in such an event, proper documentation and referral to tertiary centre will help in decreasing morbidity and further litigation.

Forgotten biliary stents: ignorance is not bliss.

BACKGROUND: Endoscopic biliary stenting is a common procedure in routine gastroenterology practice. Plastic stents are the most common type of stents used and are indicated mainly for short-term biliary drainage. Prolonged indwelling plastic stents can result in disastrous complications. METHODS: We conducted a retrospective analysis of patients who presented with complications of forgotten biliary stents in a tertiary care hospital during January 2010 to October 2016. All patients were managed either by endoscopic or surgical means. Details of these patients were obtained from departmental patient database, endoscopy records, and surgical register. RESULTS: A total of 21 cases of retained biliary stents were managed in the study period and their outcome was analyzed. The median age was 47 years (range 17-70 years) and 17 (80.9%) patients were female. Primary indication of biliary stenting was stone disease in 76.2% (n = 16), while benign biliary stricture accounted for 19% of cases (n = 4). Mean duration at presentation to hospital after ERCP stenting was 3.53 years (range 1-14 years), with cholangitis being the most common presentation (66.67%). Definitive endoscopic treatment for forgotten stent and its associated complication was possible only in five patients (23.8%); in remaining 16 (76.2%) cases, surgical exploration was required. Despite life-threatening complications and major surgical interventions, no mortality was recorded. CONCLUSIONS: Instances of forgotten biliary stents presenting with serious complications are not uncommon in Indian setup. Patients either ignore advice for timely stent removal or are unaware of the presence of endoprosthesis or need for removal. Adequate patient counseling, information, and proper documentation are essential to avoid this condition.

Improving quality of care for perinatal and newborn care at district and subdistrict hospitals in Haryana, India: Implementation research protocol.

AIM: This implementation research aims to improve quality of care for mothers and newborns in three districts of Haryana, India at different public health facilities. BACKGROUND: The decline in key maternal and newborn health indicators in India is relatively slower than expected and missed the millennium development goals. The multifold rise in institutional delivery in last decade has limited impact on neonatal and maternal mortality. Despite investments in infrastructure, equipment, supplies, monitoring tools, and also manpower, suboptimal gains in indicators point towards potential challenge in quality of care. DESIGN: This study adopts pre-post, quasi-experimental study design with repeated observations using mixed research methods to document the impact of the plan-do-study-act implementation cycles. METHODS: The quality improvement interventions shall be implemented at three district hospitals and six-first referral unit hospitals in three districts of Haryana targeting the antenatal, delivery, newborn care services with nurses as the key partners. Formative research, situational analysis, and root-cause analysis shall inform the contextualization, prioritization of interventions. Incremental plan-do-study-act cycles over 15 months shall be implemented. The changes in adherence to protocols, appropriate documentation, reduction in delays, and client satisfaction shall be documented for 16 indicators across delivery, antenatal, and sick newborn care domains. DISCUSSION: The successful implementation of the quality improvement processes has the potential of improving the pregnancy outcomes in terms of stillbirths, maternal, and newborn mortality and sick newborn outcomes. The feasibility and learning of coimplementation in the public health system shall inform integration into standards and scaling up.

Liver hydatid cyst with cystobiliary communication: Laparoscopic surgery remains an effective option.

INTRODUCTION: Most centres offer laparoscopic treatment for liver hydatid cyst (LHC). There have been concerns about the management of intra-peritoneal spillage, bleeding, and cystobiliary communication (CBC) during laparoscopic surgery for LHC. CBC can exist in 13%-37% of cases of LHC. No randomised studies have compared open versus laparoscopic approach for the treatment of LHC. We specifically analysed the outcomes of laparoscopic treatment of LHC with special reference to associated biliary complications. PATIENTS AND METHODS: We analysed our prospectively collected data of patients undergoing laparoscopic treatment of LHC from 2009 to 2016. Patients undergoing open surgery or interventional radiology procedures were not included. Data analysed included demographic profile, investigational parameters, intra-operative findings and postoperative results with special reference to biliary complications and presence/management of CBC. RESULTS:: A total of 41 patients underwent laparoscopic treatment of LHC. History of jaundice was present in 5 (12.2%) patients. CBC was documented in 16 (39.02%) patients. In 11 patients, CBC was detected intra-operatively as visible communication, which was suture ligated or clipped. Five patients had occult CBC, detected as bile leak in the post-operative period. The leak resolved spontaneously in 7 patients and with biliary stenting in 2 patients. Only one patient had a persistent biliary leak. Postoperative bile leak was more common in patients with raised alkaline phosphatase. No statistically significant association was seen with size or location of the cyst, number of cysts and World Health Organisation classification. CONCLUSION: Laparoscopic treatment of LHC with associated CBC provides acceptable results.

Laparoscopic ventral rectopexy: A viable option in procidentia with redundant sigmoid - An Indian perspective.

INTRODUCTION: Laparoscopic ventral mesh rectopexy (LVMR) has gained widespread acceptance for the management of complete rectal prolapse (CRP). However, there have been concerns considering its use in patients with a redundant sigmoid colon. This study was conducted to evaluate the anatomical and functional results following LVMR, particularly in cases of CRP with a redundant sigmoid colon. MATERIALS AND METHODS: Retrospective analysis of 25 patients who underwent LVMR from January 2011 to September 2016 was performed. Patients were divided into two groups according to the duration of follow-up. Group A (long-term) with follow-up >3 years and Group B (mid-term) <3 years. RESULTS: The study included 25 patients (M:F = 1.5:1) with a median age of 38 years. Eighty-eight percent of the patients had a redundant sigmoid colon. Significant improvement in post-operative Wexner score as compared to pre-operative values was seen in patients with pre-existing constipation (P < 0.0001). In patients presenting with faecal incontinence (FI), significant improvement in post-operative St. Mark's incontinence score was observed. Functional outcomes remain consistent in long-term follow-up (>3 years). CONCLUSIONS: LVMR seems to be a feasible surgical procedure with minimum morbidity and good long-term functional outcomes. It provides satisfactory results in patients with redundant sigmoid colon and improves pre-existing constipation and FI.

Purinergic Antagonism Prevents Mitochondrial Dysfunction and Behavioral Deficits Associated with Dopaminergic Toxicity Induced by 6-OHDA in Rats.

Purinoceptors are present in neurons, microglia and oligodendrocytes and regulate dopamine (DA) release, striatal-related function and striatal neuronal and DA cells damage. Therefore, purinoceptors may be involved in the pathology of Parkinson's disease (PD) and purinergic antagonism may show neuroprotective effect. The study investigated the role of the non-selective purinergic receptor antagonist pyridoxalphosphate-6-azophenyl-2', 4'-disulfonic acid (PPADS) and a selective purinergic receptor P2X7 receptor antagonist Brilliant Blue G (BBG) against 6-OHDA induced dopaminergic neurotoxicity in rats; while adenosine triphosphate (ATP) was used as a P2X receptor agonist. Behavioral parameters like spontaneous motor activity, narrow beam walk, footprint, bar catalepsy, grip strength and rotarod tests were performed to evaluate motor deficits in PD. Striatal DA contents were estimated as neurochemical measures of PD. Mitochondrial studies and oxidative status were assessed to investigate the mechanism of purinergic system antagonists. Involvement of purinergic receptors in apoptosis was assessed by expressing cytochrome-C, caspase-9 and caspase-3. Both the antagonists not only attenuated 6-OHDA induced motor deficits but also protected against 6-OHDA induced DA depletion in the striatum. Oxidative stress, mitochondrial integrity and dysfunction were attenuated by purinergic antagonists. Further, they attenuated mitochondrial-linked apoptosis as observed by a decrease in expression of cytochrome-C, caspase-9 and caspase-3. Therefore, purinoceptor antagonism shows neuroprotective effect in 6-OHDA induced dopamine toxicity through preservation of mitochondrial bioenergetics and anti-apoptotic activities.

Dynamic article: composite antropyloric valve and gracilis muscle transposition for total anorectal reconstruction: a preliminary report.

BACKGROUND: Technique and functional outcomes of anorectal reconstruction using an antropyloric graft have been reported previously. This technique had reasonable initial outcomes but lacked voluntary function. OBJECTIVE: We hereby report the initial results of patients who underwent gracilis muscle wrapping around the perineally transposed antropyloric valve in an attempt to improve voluntary fecal control. SETTING: This study was conducted at a single tertiary care institution. PATIENTS: Eight adult patients (7 men and 1 woman) with a median age of 38 years (range, 19-51 years) underwent this procedure. Seven patients already had anorectal reconstruction with a transposed antropyloric valve, and 1 patient with severely damaged anal sphincter complex underwent single-stage composite antropylorus transposition with a gracilis muscle wrap. MAIN OUTCOME MEASURES: The primary outcome measures were anatomical integrity and functional status of the composite graft in the perineum. RESULTS: No operative mortality or serious procedure-related morbidity occurred in any patient. The median postoperative resting pressure was 29 mmHg (range, 22-38 mmHg) and squeeze pressure was 72.5 mmHg (range, 45-267 mmHg). There was a significant improvement in the squeeze pressure following surgery (p = 0.039). Also, the St. Mark's incontinence scores significantly improved in all patients and varied between 7 and 9 (p = 0.003). The ability to defer defecation and the reduced frequency of leakage accidents were the prime reasons for improved postgraciloplasty outcomes in these patients. On personal interviews, all patients who underwent this procedure were satisfied with the results of their surgery. LIMITATIONS: A longer follow-up with a larger sample size is required. Quality-of-life data have not been evaluated in this study. CONCLUSIONS: Gracilis muscle wrapping around a perineally transposed antropyloric valve is possible and improves the voluntary control and overall functional outcomes in a select group of patients with end-stage fecal incontinence requiring anal replacement (Supplemental Digital Content 1, http://links.lww.com/DCR/A173).
