The effect analysis of gastric peroral endoscopic myotomy in the treatment of 14 cases of gastroptosis / 中华消化杂志

Objective:Analyze the efficacy and safety of gastric peroral endoscopic myotomy (G-POEM) in the treatment of gastroptosis.Methods:From August 1, 2016 to August 1, 2020, at Zhongda Hospital, Southeast University, the baseline data of 14 patients with gastroptosis who underwent G-POEM were retrospectively collected, including age, weight, length of hospital stay, and modified gastroparesis cardinal symptom index(mGCSI). Regular follow-ups were made, and relevant data were recorded for comparative analysis. The main observation indicators were body weight and mGCSI. Friedman rank sum test and Bonferroni correction test were used for statistical analysis.Results:The age of 14 patients with gastroptosis was 50.0 years old(24.5 years old), the operations were successfully completed in all patients without any serious surgical complications, the time of hospital stay was 10.5 d (5.0 d), and all the postoperative follow-up time was >12 months. There were statistically significant differences in mGCSI and body weight between before operation and at 1st week, 1st month, 3rd month, 6th month, and 12th month after operation (1.94(1.19), 0.78(0.47), 0.36(0.19), 0.17(0.45), 0.13(0.57) and 0.29(0.50), 43.5 kg(5.8 kg), 43.5 kg(5.8 kg), 42.5 kg(7.1 kg), 43.5 kg(6.9 kg), 45.0 kg(8.0 kg) and 45.5 kg(7.5 kg); Z=42.78 and 34.28, both P<0.001). After Bonferroni correction in the pairwise comparison, there were statistically significant differences in the mGCSI of the 14 patients between before operation and at 1st month, 3rd month, 6th month, and 12th month after operation ( Z=4.09, 5.05, 5.00 and 4.14, P=0.001, <0.001, <0.001 and =0.001). The weight of 14 patients at 12th month after operation were compared with the weight before operation, 1st week after operation, and 1st month after operation, and the differences were statistically significant (all Z=-3.64, all P=0.004). Conclusion:G-POEM has a good therapeutic effect on patients with gastroptosis and is expected to become a new treatment for gastroptosis.

ABSTRACT Hypertrophic stenosis of the pylorus is the partial or complete obstruction of the pylorus lumen, its muscles are so strongly thickened that gastric emptying is difficult. Although the diagnosis is basically clinical, imaging studies are decisive to confirm the disease. A retrospective descriptive study was carried out in 119 patients with clinical manifestations of hypertrophic pyloric stenosis, whose diagnosis was confirmed by imaging studies, at the "William Soler" University Pediatric Hospital from 2000 to 2015. The ultrasound measurements were the length of the pyloric channel ≥ 16mm in 95.8%, the wall of the pyloric muscle in 88.2% and pyloric olive diameter in 68.1% of the patients. In 90 children, the diagnosis was done by initial abdominal sonography. The remaining 29 were done barium upper gastrointestinal studies under fluoroscopic vision, observing the string sign in 100%, gastric dilatation in 72.4% and delayed gastric emptying in 58.6%. With a second positive abdominal sonography. Corroborating the diagnosis in the surgical act. Abdominal sonography was a highly positive and sensitive diagnostic study, with the length of the pyloric canal as the main ultrasound measurement and the string sign the major radiological finding.

ABSTRACT Hypertrophic pyloric stenosis is characterized by hypertrophy and hyperplasia of the muscle fibers and narrowing of the pyloric canal, which causes non-bilious vomiting, giving rise to one of the most common causes of surgical treatment in the newborn stage. A retrospective descriptive study was carried out in 119 patients with a diagnosis of hypertrophic pyloric stenosis at the "William Soler" University Pediatric Hospital from 2000 to 2015. 70.6% of the children were between three and five weeks old and 83.2% a weight at diagnosis between 2500 g to 4500 g. Vomiting was present in all patients, alterations in body weight in 79.8% and hydroelectrolyte and basic acid imbalances in 53.8%. Male sex, white racial appearance, being first-born, and artificial or mixed breastfeeding were significant prevalent risk factors associated with the disease (p <0.05). Hypertrophic pyloric stenosis was most frequently diagnosed at the 4th week of life and in children weighing between 3000 and 4500 g. The weight variations denote the importance of following the weight curve in these patients.

Peroral endoscopic myotomy in a pediatric patient with refractory achalasia: a case report and review of the literature

A 15-year-old male patient presented with dysphagia, regurgitation, weight loss and retrosternal pain. The diagnosis of achalasia was made 4 years before. The esophagogram revealed severe esophagus dilatation and the classic "bird-beak" termination. A Heller myotomy plus fundoplication and endoscopic balloon dilatation were conducted four months previously. Nevertheless, the symptoms persisted and the last high-resolution manometry study still showed achalasia type II. The patient underwent a peroral endoscopic esophageal myotomy (POEM). POEM is a feasible and safe procedure for experienced and properly- equipped health care delivery centers and could be used as a rescue treatment in refractory achalasia. We present the youngest patient with achalasia in our region who had a successful response to rescue POEM.

Un paciente varón de 15 años, con el diagnóstico de acalasia realizado 4 años antes, acudió a evaluación por presentar disfagia, regurgitación, pérdida de peso y dolor restroesternal. El esofagograma baritado evidenció una dilatación severa del esófago y la terminación clásica en "pico de pájaro". El paciente había sido sometido a una miotomía de Heller más fundoplicatura y posteriormente a una dilatación esofágica con balón 4 meses atrás. Sin embargo, los síntomas persistían y la última manometría de alta resolución reveló acalasia tipo II. Finalmente, se realizó una miotomía endoscópica por vía oral (POEM); el cual es un procedimiento seguro y accesible en centros experimentados y debidamente equipados, pudiendo ser una adecuada opción de tratamiento en casos de acalasia refractaria. Presentamos el caso del paciente más joven en nuestra región con acalasia con una respuesta exitosa a un POEM de rescate.

Adult idiopathic hypertrophic pyloric stenosis: an infrequent cause of gastric outlet obstruction

Hypertrophic pyloric stenosis is a congenital disease, presenting within two weeks of birth. However adult idiopathic hypertrophic pyloric stenosis (AIHPS) presents in middle age, predominantly in males and usually without any antecedent cause. Secondary variant may be due to intra gastric causes or extra gastric post-operative adhesions. Patient presents with symptoms of gastric outlet obstruction. Diagnosis depends on clinical, radiological and endoscopic findings. Treatment is subtotal gastrectomy. Pyloroplasty and endoscopic dilatation may be tried in debilitated patients. We present a case of AIHPS presenting as gastric outlet obstruction in a 16 year old female, that was surgically managed with an antrectomy.

Comparison of the curative effect between laparotomy and laparoscopic pyloromyotomy in the treatment of congenital hypertrophic pyloric stenosis / 新乡医学院学报

Objective To compare the clinical effect between laparotomy and laparoscopic pyloromyotomy in the treatment of congenital hypertrophic pyloric stenosis (CHPS).Methods Sixty-three children with CHPS were selected from March 2010 to July 2016 in the Second People's Hospital of Luohe City.The children were divided into laparoscopic operation group (n =31) and laparotomy group (n =32) according to the treatment methods.The children in the laparoscopic operation group were treated with laparoscopic pyloromyotomy,and the children in the laparotomy group were treated with laparotomy.The operation time,intraoperative blood loss,postoperative recovery feeding time,hospitalization time,complications,intragastric pressure and lower esophageal sphincter pressure (LESP) were compared between the two groups.Results There was no significant difference in operation time between the two groups (t =0.277,P ＞ 0.05).The postoperative hospitalization time and recovery feeding time in the laparoscopic operation group were significantly shorter than those in the laparotomy group (t =14.302,17.935;P ＜0.05),and the intraoperative blood loss in the laparoscopic operation group was significantly less than that in the laparotomy group (t =13.064,P ＜ 0.05).There was no significant difference in the intragastric pressure and LESP between the two groups before operation (t =0.316,0.529;P ＞ 0.05).The intragastric pressure after operation was significantly lower than that before operation in the two groups (t =10.613,9.851;P ＜0.05).There was no significant difference in LESP before and after operation in the two groups (t =2.643,2.772;P ＞ 0.05).There was no significant difference in the intragastric pressure and LESP between the two groups after operation (t =0.237,0.329;P ＞ 0.05).The incidence of postoperative complications in the laparotomy group and laparoscopic operation group was 15.63％ (5/32) and 3.23％ (1/31) respectively,the incidence of complications in laparoscopic operation group was significantly lower than that in laparotomy group (x2 =3.991,P ＜ 0.05).Conclusion laparoscopic pyloromyotomy can effectively relieve pyloric stenosis in the treatment of CHPS,and it has the characteristics of small trauma,quick recovery and less complications.

Research advances in the surgical approach of congenital hypertrophic pyloric stenosis / 国际儿科学杂志

Congenital hypertrophic pyloric stenosis(CHPS)is a common gastrointestinal congenital mal-formation in neonate and small infants.Pyloromyotomy is an effective method for treatment of CHPS,including several methods.Traditional open pyloromyotomy for the patient's body injury is serious,such as accident of an-esthesia,postoperative infection,skin scar;laparoscopic pyloromyotomy can cause the pylorus muscle incision uncomplete,invasive operation damage,etc.Endoscopic pyloromyotomy for neonatal has some advantages:a lit-tle injury,no scars,simple operation,less complications,quicker recovery of feeding.Endoscopic mucosal pyloro-myotomy may be a new method of treatment,needing further exploration and research.

Outcomes of Laparoscopic Pyloromyotomy with Microscope and Stab Incision vs. Open Pyloromyotomy in Infantile Hypertrophic Pyloric Stenosis; Single Institution Experience

PURPOSE: We attempted to evaluate the outcomes of a newly inaugurated surgical technique of laparoscopic pyloromyotomy with microscope and stab incision (MS-LP) with right upper quadrant transverse open pyloromyotomy (RT-OP), which were performed in a single institution. METHODS: The outcome variables in terms of total anesthesia time, operative time, postoperative emesis, time to full-enteral feeding, postoperative hospital stay, cosmetic result score, medical cost, and postoperative wound complications were compared between the MS-LP and RT-OP groups. RESULTS: Fifty-one consecutive pyloromyotomy cases were enrolled; MS-LP (n=33) and RT-OP (n=18). There was no difference in age, pyloric thickness, and preoperative electrolyte levels between the two groups. The total anesthesia time and operative time of MS-LP were not significantly longer than that of RT-OP. Time to full-enteral feeding and postoperative hospital stay were shorter in MS-LP (20.0±18.3 vs. 35.3±14.8 hrs. and 2.4±1.3 vs. 3.4±1.2 days; p=0.047 and 0.050, respectively). The cosmetic result score and medical cost were significantly higher in MS-LP (9.1±1.0 vs. 7.3±1.2 in terms of scores and 3,501,950±1,093,147 vs. 2,522,474±68,605 in terms of KRW; p=0.001 and 0.021, respectively). No difference in postoperative wound complications was observed between the two groups. CONCLUSION: Laparoscopic pyloromyotomy with microscope and stab incision may suggest recovery benefits with a shorter time to full-enteral feeding and postoperative hospital stay, as well as better cosmetic results than RT-OP. However, MS-LP may induce higher costs.

Ultrasound-guided paravertebral block for pyloromyotomy in 3 neonates with congenital hypertrophic pyloric stenosis / Bloqueio paravertebral guiado por ultrassom para piloromiotomia em 3 recém-nascidos com estenose hipertrófica de piloro congênita / Bloqueo paravertebral ecoguiado para la piloromiotomía en 3 neonatos con estenosis hipertrófica de píloro congénita

Hypertrophic pyloric stenosis is a relatively common affection of gastrointestinal tract in childhood that results in symptoms, such as projectile vomiting and metabolic disorders that imply a high risk of aspiration during anesthetic induction. In this way, the carrying out of a technique with general anesthesia and intravenous rapid sequence induction, preoxygenation and cricoid pressure are recommended. After the correction of systemic metabolic alkalosis and pH normalization, cerebrospinal fluid can keep a state of metabolic alkalosis. This circumstance, in addition to the residual effect of neuromuscular blocking agents, inhalant anesthetics and opioids could increase the risk of postoperative apnea after a general anesthesia.

A estenose hipertrófica do piloro é uma condição relativamente comum do trato gastrintestinal na infância, que causa um quadro de vômitos em jato e alterações metabólicas que envolvem um alto risco de aspiração durante a indução da anestesia. Assim, recomenda-se uma técnica sob anestesia geral e indução intravenosa de sequência rápida, pré-oxigenação e pressão cricoide. Após a correção da alcalose metabólica sistêmica e normalização do pH, o líquido cerebrospinal pode manter um estado de alcalose metabólica. Isso, juntamente com os efeitos residuais de agentes bloqueadores neuromusculares, anestésicos e opioides, pode aumentar o risco de apneia pós-operatória após anestesia geral.

La estenosis hipertrófica de píloro es una afección relativamente común del tracto gastrointestinal en la infancia, que conlleva un cuadro de vómitos en proyectil y alteraciones metabólicas que implican un elevado riesgo de aspiración durante la inducción anestésica. Así, se recomienda la realización de una técnica con anestesia general e inducción de secuencia rápida intravenosa, preoxigenación y presión cricoidea. Tras la corrección de la alcalosis metabólica sistémica y normalización del pH, el líquido cefalorraquídeo puede mantener un estado de alcalosis metabólica. Esta circunstancia, junto con el efecto residual de los bloqueantes neuromusculares, agentes anestésicos inhalatorios y opioides podrían incrementar el riesgo de apnea postoperatoria tras una anestesia general.

Estenosis hipertrófica pilórica infantil / Hypertrophic pyloric stenosis child

La estenosis hipertrófica infantil representa la condición más común que requiere resolución quirúrgica en la infancia temprana. La función y motilidad del píloro está guiada por distintos sistemas que involucran sistema nervioso entérico, hormonas gastrointestinales y las células intersticiales de Cajal, es así como distintos factores que afecten dichos componentes se ven involucrados en las distintas hipótesis de la fisiopatogenia de la enfermedad. El diagnóstico se basa clásicamente en historia clínica, examen físico y estudios de imágenes. El manejo ha sido clásicamente quirúrgico, mediante la piloromiotomía de Ramstedt, sin embargo se ha planteado manejo farmacológico mediante sulfato de atropina.

Infantile hypertrophic stenosis is the most common condition requiring surgical intervention in early childhood. The function and motility of the pylorus is guided by different systems involving enteric nervous system, gastrointestinal hormones and the interstitial cells of Cajal, is how different factors affecting these components are involved in the different hypotheses of pathogenesis of the disease. The diagnosis is typically based on clinical history, physical examination and imaging studies. The surgical management has been classically by Ramstedt pyloromyotomy, however pharmacological management has been raised by atropine sulfate.

Comparison of Pyloromyotomy with Supraumbilical Incision and Laparoscopic Pyloromyotomy for Hypertrophic Pyloric Stenosis Performed by a Single Surgeon / 소아외과

PURPOSE: Hypertrophic pyloric stenosis (HPS) is known to be one of the most common cause of surgery for infants and pyloromyotomy was considered to the standard treatment. There has been an ongoing debate about whether laparoscopic pyloromyotomy (LP) or open pyloromyotomy (OP) is the best option for treating HPS. The aim of this study is to evaluate safety and effectiveness of LP by comparing the clinical results of both surgical strategies performed by single surgeon. METHODS: Between January 2000 and December 2013, 60 patients who underwent pyloromyotomy at Asan Medical Center performed by a surgeon were followed: open-supraumbilical incision (n=36) and LP (n=24). The parameters included sex, age and body weight at operation. Clinical outcomes included operation time, time to full feeding, postoperative hospital stay, and postoperative complications. RESULTS: There were no significant differences in characteristics, postoperative hospital stay between the two groups. Time to full feeding was shorter in LP (OP 24.5 hours vs. LP 19.8 hours; p=0.063). In contrast, the mean operation time was longer in LP (OP 37.5 minutes vs. LP 43.5 minutes; p=0.072). Complications such as perforation of mucosal layer (OP 1 vs. LP 0) and wound problems (OP 2 vs. LP 0) were found to be not worse in laparoscopic group as compared with open group. CONCLUSION: There has no difference both laparoscopic and open-supraumbilical incision in terms of postoperative hospital stay, time to full feeds and frequency of complications.

Efficacy and safety of laparoscopic pyloromyotomy and open pyloromyotomy for the treatment of congenital hypertrophic pyloric stenosis:Meta analysis / 中华实用儿科临床杂志

Objective To evaluate the efficacy and safety of laparoscopic pyloromyotomy (LP) or open pyloromyotomy (OP) for the treatment of congenital hypertrophic pyloric stenosis(CHPS),and to provide a basis for reasonable treatment programme for clinic.Methods Randomized control trials (RCTs) about LP and OP for the treatment of CHPS were searched using Cochrane library,PubMed,Embase,Cumulative Index To Nursing And Allied Health Literature (CINAHL),Web of Science,Chinese biomedical literature database and China National Knowledge Internet database.Study selection and Meta analysis were conducted according to the Cochrane Handbook for systematic reviews.Extracted data from the selected studies were reviewed by the reviewers and analyzed using RevMan 5.1 software.Results Five RCTs with a total of 552 patients fulfilled the inclusion criteria and were analyzed in this review.Meta analysis showed that there was no statistically significant differences in incidence of postoperative complications between LP and OP (OR =2.59,95 ％ CI:0.90-7.47).Compared with OP,the postoperative recovery eating time and postoperative hospital stay in patient with LP were significantly reduced (MD =-3.63,95％ CI:-5.19--2.06) ;MD =-12.62,95 ％ CI:-16.13--9.11).Conclusions LP result in earlier feeding,shorter hospital stay,less trauma with superior cosmetic outcome and earlier recovery of the patient than the OP.But the postoperative complication between the two surgeries still remains the topic of concern.

Laparoscopic Versus Open Pyloromyotomy for Hypertrophic Pyloric Stenosis

PURPOSE: Hypertrophic pyloric stenosis (HPS) is a common condition affecting infants that causes severe projectile non-bilious vomiting in the first few months of life. Although open pyloromyotomy is the standard treatment for HPS, recently, the laparoscopic approach has rapidly been adopted by pediatric surgeons. The aim of this study is to determine the efficacy and safety of laparoscopic pyloromyotomy by comparing the clinical results of laparoscopic and open pyloromyotomy. METHODS: Between January 2007 and September 2012, a cohort of 69 children who underwent pyloromyotomy at Seoul National University Children's Hospital were followed; open pyloromyotomy (OP, n=56) and laparoscopic pyloromyotomy (LP, n=13). A retrospective analysis of patient's characteristics and clinical outcomes in patients with open or laparoscopic pyloromyotomy for HPS was performed. The evaluated characteristics included gestational age, sex, birth weight, age and weight at operation. Clinical outcomes included operation time, length of hospital stay, time to postoperative full feeds without vomiting, number of postoperative vomiting and complications. RESULTS: There were no significant differences in characteristics, length of hospital stay and time to postoperative full feeds without vomiting between the two groups. Incidence of postoperative vomiting in the LP group was significantly lower than that in the OP group (OP: 5.07+/-4.60 vs. LP: 2.00+/-2.16, p=0.035). In contrast, the operation time was longer, following the LP group (OP: 26.30+/-9.95 vs. LP: 44.15+/-19.56, p0.999) and wound problems (OP: 4 vs. LP 1, p>0.999) were found to be similar in both groups. CONCLUSION: Both open and laparoscopic pyloromyotomy are safe procedures for the management of hypertrophic pyloric stenosis. Incidence of vomiting was statistically superior in the laparoscopic group. In addition, postoperative complications were fewer in this group. However, an improvement in the operation time will be needed for the future development of laparoscopic pyloromyotomy.

Infantile Hypertrophic Pyloric Stenosis - Experiences of 77 Cases.

Infantile hypertrophic pyloric stenosis (IHPS) is the most common cause of gastric outlet obstruction in infants which needs surgical treatment. The aim of this study was to review the management of IHPS in our hospital to compare with other developed centers. This is a prospective analytical study carried out in the Department of Pediatric Surgery, Faridpur Medical College Hospital and Dr. Zahed Children Hospital at Faridpur, during the period of May 2002 to October 2010. Total 77 patients were treated by Ramstedt's pyloromyotomy after proper diagnosis and resuscitation. The male to female ratio was 10:1. Most of the patients presented to us within 40 days of age (90%).Younger one was 15 days and elder one was 69 days. In all cases diagnosis were done on clinical basis. The diagnosis is confirmed by barium meal x-ray in 71 cases and sonogram in 15 cases. Serum electrolytes were not estimated in all patients. There was moderate to severe dehydration in more than 60% cases. 71 cases were operated under general anesthesia and 06 cases were operated with local anesthesia. There was one postoperative death on 4th post-operative day. Oral feeding started after 8 to 10 hours postoperatively in all cases. Mucosal perforation occurred in 1 case and that was recognized and treated conservatively without any ill effect. Superficial wound infection encountered in 3 cases. Early diagnosis, preoperative correction of dehydration and electrolyte imbalance and experiences of surgeons play important role for management of IHPS.

Comparison of Outcomes between Open and Laparoscopic Pyloromyotomy

Hypertrophic pyloric stenosis (HPS) is the most common infantile surgical condition and the standard treatment is open pyloromyotomy. Recently, laparoscopic techniques have rapidly advanced, and the laparoscopic approach has become widely adopted by pediatric surgeons. The aim of this study was to compare the clinical outcomes between open and laparoscopic pyloromyotomy. We retrospectively evaluated outcomes of pyloromyotomy for HPS by the open (OP) and the laparoscopic (LP) method. The procedures were performed at the Samsung Medical Center between September 2001 and March 2009. We analyzed patient age, sex, birth weight, length of hospital stay, postoperative length of stay (LOS), operating time, time to feeding commencement, postoperative vomiting frequency, the time to full feeding without vomiting, and surgical complications. A total of 54 patients were included in the study. There were 26 OP and 28 LP patients. There was no statistically significant difference in age, sex, birth weight, operating time, postoperative emesis. In contrast, postoperative LOS in the LP group was statistically significantly shorter than that in the OP group (2.0 vs. 3.3 days, p=0.0003) and time to full feeding was significantly shorter following LP. (p=0.018) There were no wound complications. Laparoscopic pyloromyotomy significantly reduced postoperative LOS and time to full feeding compared to open pyloromyotomy.

Twins with congenital hypertrophy of infantile pyloric stenosis

Congenital hypertrophy of infantile pyloric stenosis (CHIPS) is an acquired condition where the thickened pyloric sphincter causes high grade gastric outlet obstruction. The incidence is higher in the West compared to the East. Over a 15 years period, there has only been a single case of pyloric stenosis in a patient of Caucasian descent in our local setting. A rare and interesting set of six weeks old male twins with CHIPS is reported. Both patients responded well to pyloromyotomy.

Clinical Analysis of the Infantile Hypertrophic Pyloric Stenosis

PURPOSE: Infantile hypertrophic pyloric stenosis (IHPS) is a common surgical emergency of infants that exhibits clearly unique characteristic symptoms, but its etiology and pathogenesis are still obscure. The Fredet-Ramstedt pyloromyotomy has gained worldwide acceptance. The advantages of this operation are immediate solution of the problem and few complication. Cosmetically circumumbilical incision or laparoscopic pyloromytomy can be used. METHODS: Forty cases of IHPS admitted to the Chuncheon Sacred Heart Hospital from Jan 1997. to Dec 2002 were reviewed retrospectively. These cases underwent Fredet-Ramstedt's operation. RESULTS: The most prevalent age group was 21~30 days (10 cases: 25%), mean age was 41.4+/-9.9 days, and the males to females ratio was 4.7: 1. Among the 40 cases, 24 (60%) involved the first baby. The mean gestation age was 39.9+/-1.7 weeks and mean birth weight was 3.3+/-0.5 Kg. The mean duration of symptom was 4.1+/-1.6 days. The common symptoms were non-bile stained, projectile vomiting in all cases, an olive-shaped mass in the right upper quadrant abdomen in 21 cases (52.5%), visible peristalsis on epigastrium in 16 cases (40%), and jaundice in 1 case (2.5%). Hypokalemic alkalosis was observed in 3 cases (7.5%). The mean length and thickness of the stenotic canal, as measured in the operation, were 28.8+/-8.5 mm and 4.9+/-0.6 mm, respectively. Postoperative complications were one case each (2.5%) pneumonia, wound seroma, and recurrence. Conclusion: Fredet-Ramstedt's pyloromyotomy for IHPS is an effective operation after the correction of dehydration and electrolyte imbalance.

Two Cases of Successful Treatment with Atropine Sulfate in Persistent Vomiting beyond Pyloromyotomy of Infantile Hypertrophic Pyrolic Stenosis

Infantile hypertrophic pyloric stenosis (IHPS) is the most common condition requiring abdominal surgery in early infancy, and is caused by hypertrophied pyloric muscle. The development of successful surgical treatment in the early 1900s by Fredet and Ramstedt made it possible for infants worldwide to survive. Modern pediatric anesthetic techniques have virtually eliminated mortality from surgical management. Atropine sulfate is a cholinergic blocking agent with potent antimuscarinic activity that decreases peristaltic contractions by relaxing smooth muscles. We treated two cases of IHPS with incomplete pyloromyotomy in 3-month-old and 5-month-old male infants by administering atropine sulfate intravenously. They were free from vomiting after 5 days of intravenous atropine sulfate treatment. In these rare cases of persistent vomiting or refractory emesis following incomplete pyloromyotomy, there may be a role for atropine sulfate.

Clinical Study of Infantile Hypertrophic Pyloric Stenosis

BACKGROUND: Infantile Hypertrophic Pyloric Stenosis (IHPS) is one of the most common surgical problems of early infancy and one for which an eminently successful surgical treatment has been available since the work of Ramstedt in 1912. A clinical study was begun to access further the accuracy of ultrasonography in identifying hypertrophic pylorus. METHODS: This study is a retrospective clinical analysis of 31 cases of IHPS treated at the Department of Surgery of Pohang St. Mary's Hospital from Jan. 1990 to Dec. 1997. RESULTS: (1) The most prevalent age group was between 3 weeks and 8 weeks in 24 cases (77.4%), and the ratio of males to females was 5.2:1. (2) Among the 31 cases, new born babies were 21 cases (67.7%). (3) In 30 cases (96.8%), the gestational age was between 37 weeks and 42 weeks, and the birth weight was more than 3.5 kg in 21 cases (67.7%). The body weight percentile at admission was lower than the 50 percentile in 31 cases. (4) Among the 31 cases, breast-fed infants were 15 cases (48.4%), milk-fed 13 cases (41.9%), and mixed-fed 3 cases (9.7%). B type blood group was 23 cases (74.2%), and O type was 4 cases (12.9%). (5) In 4 cases (12.9%), an inguinal hernia was noted as an associated anomaly. (6) The onset of symptoms was neonatal (1 week-12 weeks) in all 31 cases, and the duration of the symptoms was between 1 week and 2 weeks in 18 cases (58.1%). (7) Non-bile stained, projectile vomiting was noted in all 31 cases (100.0%), an olive-shaped mass in right upper quadrant of the abdomen was felt in 27 cases (87.1%), and visible peristalsis on the epigastrium was noted in 25 cases (80.6%). (8) On laboratory tests, 17 patients had leukocytosis, and anemia was observed in 2 cases. Hypokalemia was observed in 9 cases (29.0%), hypochloremia in 4 cases (12.9%), and moderate to severe alkalosis (CO2 content > 25 mEq) in 7 cases. (9) Among the 25 cases, for which an the ultrasonographic evaluation was performed, the length of the stenotic canal was from 16 mm to 20 mm in 23 cases (92.0%), and the thickness of the stenotic portion was from 5 mm to 6 mm in 21 cases (84.0%). (10) All 31 cases were surgically treated by using a Fredet-Ramstedt pyloromyotomy, and the mortality was nil. The average hospitalization was 9.4 days. (11) There was 1 case of duodenal perforation and 1 case of intermittent non-projectile vomiting after the operation. CONCLUSIONS: We conclude that early accurate diagnosis, adequate preoperative preparation of the fluid & electrolyte imbalance, immediate surgical correction, and scheduled careful oral feeding are important in treatment of IHPS. Ultrasonographic determination of pyloric muscle length and thickness is the most accurate of the currently available techniques. A Fredet-Ramstedt pyloromyotomy is a safe and successful surgical procedure.
