Is ERCP manometry useful in the choice of treatment of stones of the common bile duct?

Summary To verify the appropriateness of sphincterotomy as the treatment of choice of choledocholithiasis, since 1980 we have been using endoscopic retrograde cholangiopancreatographic (ERCP) manometry of the sphincter of Oddi (SO). This method allows direct investigation of SO motor activity and provides useful information regarding the presence of benign papillary stenosis (BPS). Thirty-four patients were investigated because the radiological examination indicated BPS might be present. Of these, 20 had common bile duct (CBD) stones, while the remaining 14 presented with biliarylike pain and one or more of the following: CBD dilation (larger than 12 mm); emptying of the ERCP contrast medium took longer than 45 min; abnormal liver function tests. Moreover, 8 healthy volunteers served as controls. Our results show that the incidence of SO motor anomalies is very low in the presence of choledocholithiasis, while it is substantial in patients with suspected SO dysfunction. These observations would suggest that, unlike the traditional view, BPS is rarely secondary to biliary lithiasis. Therefore, most of the sphincterotomies performed that are based on the assumption of underlying SO pathology should be considered unnecessary. Under these circumstances, the physiological role of a functioning SO has induced us to advocate sphincterotomy, surgical or endoscopic, in selected cases only.     

Vascular anatomy of gracilis muscle arterial findings to enhance graciloplasty

Dynamic graciloplasty has recently been developed for reconstruction of anal function in patients who are fecally incontinent in preference to permanent abdominal colostomy. Since the muscular portion of gracilis is wrapped around the neoanus, the length of the gracilis arc influences the functional outcome of graciloplasty. Although dissection of the main pedicle (i.e. the main artery and vein) can facilitate gracilis to have enough muscle arc, it has been unclear whether there are any vessels proximal to the main pedicle or through the origin of the muscle which could support blood flow into the whole of gracilis. In this study, the vascular anatomy of gracilis in both legs of 26 Japanese cadavers was examined. All muscles had a main pedicle, mean maximum diameter 1.08 mm, entering at the proximal one-third of the muscle. However, only 18 muscles (34.6%) had an accessory artery in the proximal portion in addition to the main pedicle. Some arteries always exist at the origin of the muscle, having a mean maximum diameter of 0.34 mm, suggesting that they might be able to support the whole gracilis without supply from the main pedicle.     

Cytokeratin polypeptide expression in a cloacogenic carcinoma and in the normal anal canal epithelium

Summary The aim of the present study was to explore the origin of cloacogenic carcinoma in the anal canal by immunohistochemical methods. We compared cytokeratin polypeptide expression of a cloacogenic carcinoma to normal anal epithelia, to anal squamous cell carcinoma and to basal and squamous cell carcinoma of the skin, using a battery of monoclonal anti-cytokeratin, polypeptide-specific antibodies. Our results indicate that cloacogenic carcinoma expresses cytokeratin polypeptides similar to those of the basal layer of anal squamous epithelium, of the anal transitional zone epithelium and of a layer of basal cells in the anal glands. Thus we concluded that each of the above cell types may be the cell of origin of cloacogenic carcinoma.     

Expanding the phenotypic spectrum of Mabry Syndrome with novel PIGO gene variants associated with hyperphosphatasia,intractable epilepsy,and complex gastrointestinal and urogenital malformations

Mabry syndrome is a glycophosphatidylinositol (GPI) deficiency characterized by intellectual disability, distinctive facial features, intractable seizures, and hyperphosphatasia. We expand the phenotypic spectrum of inherited GPI deficiencies with novel bi-allelic phosphatidylinositol glycan anchor biosynthesis class O (PIGO) variants in a neonate who presented with intractable epilepsy and complex gastrointestinal and urogenital malformations.     

系统化整体护理模式对肛裂患者术后疼痛及便秘的效果观察

为观察系统化整体护理模式对肛裂患者术后疼痛及便秘的效果,将肛裂手术患者184例随机分为对照组和观察组,每组92例。对照组患者术后采用常规护理,观察组患者术后采用系统化整体护理模式护理;比较2组患者术后疼痛及便秘效果。结果显示,观察组患者术后疼痛评分低于对照组(P <0.05),观察组患者3d未排便、用力排便、排便堵塞、粪便干硬比率低于对照组(P <0.05)。结果表明,系统化整体护理模式能有效缓解肛裂患者术后疼痛,改善肛裂术后患者便秘症状。     

Is barium esophagram enough? Comparison of esophageal motility found on barium esophagram to high resolution manometry

BackgroundThe aim of the study is to determine if barium esophagram (BE) alone is sufficient to diagnose esophageal dysmotility when compared to the gold standard, high-resolution manometry (HRM).MethodsThis is a retrospective review of patients that underwent laparoscopic fundoplication by two surgeons at a single institution from 10/1/2015-6/29/2019. Patients with large paraesophageal hernias and patients without both BE and HRM were excluded.ResultsForty-six patients met the inclusion criteria. BE was found to be concordant with HRM for esophageal motility in only 21 patients (46%). Setting HRM as the gold standard, BE had a sensitivity of 14% (95% CI: 5%–35%), specificity of 72% (95% CI: 52%–86%), PPV of 30% (95% CI: 11%–60%), and NPV of 50% (95% CI: 35%–66%). The accuracy was 46%, while a McNemar test showed p = 0.028.ConclusionTraditional BE should not be used in place of HRM for assessing pre-operative motility in patients undergoing anti-reflux surgery.     

Early postoperative colonic ventriculoperitoneal shunt migration with trans-anal protrusion: A unique case report

Introduction and importanceColonic ventriculoperitoneal shunt (VPS) migration with trans-anal protrusion remains uncommon. Patients may be asymptomatic, and diagnosis may only be made on visualization of the prolapsed catheter from the anus. This unique case of early post-operative trans-anal shunt protrusion highlight the possibility of this rare complication specially when shunt revision accompanies bowel surgery.Case presentationThe authors present a case of early postoperative colonic shunt migration in a thirteen-year-old female with who underwent Malone Antegrade Continence Enema (MACE) with concomitant revision of the distal part of the peritoneal catheter. She presented two weeks post operatively with shunt catheter protruding from the anus. This was noticed by her carer and she was asymptomatic on her presentation.Clinical discussionDelayed post-operative shunt related bowel perforation and trans-anal shunt protrusion is an uncommon complication after ventriculoperitoneal shunting. Most cases present months after surgery and majority are asymptomatic on presentation. The exact pathophysiology is not established, and mechanisms have been proposed. Early post -operative trans-anal shunt protrusion is rare and suggests inadvertent occult bowel injury especially when shunt placement or revision accompanies extensive bowel surgery.ConclusionThe authors recommended shunt imaging within the first two to three weeks after shunt revision in patient who undergo concomitant bowel surgery with risk of inadvertent bowel injury to identify early colonic migration and avoid its potentially fatal sequelae.

Laparoscopic rectopexy for complete rectal prolapse

Background: The purpose of this study was to evaluate the clinical outcome of laparoscopic rectopexy and its effect on anorectal function investigations. Methods: Twelve patients with complete rectal prolapse without constipation underwent laparoscopic rectopexy. Pre- and postoperative evaluation included scoring of incontinence, anorectal manometry, and anal endosonography. Results: No recurrences of rectal prolapse were seen (median follow-up 19 months). Continence improved in eight of nine preoperatively incontinent patients. Two patients had mild constipation after surgery. Median maximum basal pressure measured by anorectal manometry increased from 20 to 25 mmHg (p=0.005) and the rectoanal inhibitory reflex improved in seven patients (p=0.03). Rectal sensitivity did not change significantly. Endosonography showed asymmetry and thickening of the internal anal sphincter and submucosa preoperatively. After surgery the maximum internal anal sphincter thickness decreased from 3.0 mm to 2.6 mm (p=0.02). Conclusions: Laparoscopic rectopexy improved continence in our patients. Anorectal function tests show a partial recovery of the internal anal sphincter. Laparoscopic rectopexy combines the low morbidity of minimal invasive surgery with the good outcome of abdominal rectopexy.Presented at the annual meeting of the Society of American Gastrointestinal Endoscopic Surgeons (SAGES), Orlando, Florida, USA, 11–14 March 1995
