Application experience of prelacrimal recess combined with septotomy in resection of recurrent inverted papilloma / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the effectiveness of nasal endoscopic anterior lacrimal recess approach combined with temporary fenestration of the nasal septum in resecting recurrent nasal inverted papilloma. Methods:Patients with recurrent nasal inverted papilloma who underwent reoperation in our hospital during the past 2 years were included . The nasal septum may hinder full access to and effective treatment of the lesions at the anterior and medial wall of the maxillary sinus by endoscope, aspirator and surgical instrument in the narrow aperture of the prelacrimal recess, although these lesions could be observed by 70° nasal endoscope. Results:The nasal septum is temporarily opened on the basis of the prelacrimal recess approach, and the nasal endoscope and instrument was introduced through trans-septal window, so as to provide a better view of the operative field and the angular range of the instrument's movement. Conclusion:The recurrent nasal inverted papilloma could be successfully managed by re-endoscopic anterior lacrimal recess approach combined with temporary fenestration of the nasal septum, and no recurrence was observed during the 2-year follow-up. This surgical approach is recommended for the inverted papilla which originates from the anterior medial wall of the maxillary sinus, as the tumor can be removed completely using this surgical approach.

Septotomía endoscópica del divertículo de Zenker / Endoscopy septotomy in zenker diverticulum

Introducción: La Diverticulotomía o Septotomía endoscópica en el divertículo de Zenker, es una alternativa a otros abordajes terapéuticos. El presente estudio muestra nuestra experiencia de esta técnica endoscópica. Pacientes y Métodos: Análisis retrospectivo, entre el 2009 y 2017 en pacientes con divertículo de Zenker. La septotomía se realizó utilizando videoendoscopio flexible, esfinterótomo aguja, electrobisturi para DSE tipo Hibridknife, mediante una técnica ya estandarizada. Resultados: Se trataron 25 pacientes con edad promedio de 71 años (rango etario de 45 a 84 años). En una paciente su mejoría fue muy poca, por lo que se sometió a intervención quirúrgica, donde tampoco hubo resultados consistentes. Veintiún pacientes mostraron un alivio completo de la disfagia. Tres pacientes que tuvieron recurrencia sintomática fueron tratados con el mismo método endoscópico entre 2 y 4 sesiones evolucionando de forma satisfactoria. Conclusiones: La septotomía endoscópica del divertículo de Zenker es un método eficaz y seguro, por lo tanto representa una alternativa real a la cirugía.

Introduction: Diverticulotomy or Endoscopic septotomy in Zenker's diverticulum is an alternative to others therapeutics approaches. The present study shows our experience of this endoscopic technique. Patients and methods: Retrospective analysis between 2009 and 2017 in patients with Zenker's diverticulum. The procedure was performed using a flexible video endoscope and a needle knife, Erbe hybrid knife probe, using an already standardized technique. Results: Twenty-five patients with an average age of 71 years (age range 45-84 years) were treated. In one patient his improvement was very little, therefore surgical procedure was performed, nevertheless this procedure had not consistent results. Twenty-one patients showed complete relief of dysphagia. Three patients who had symptomatically relapsed were retreated with the same endoscopic method between 2 and 4 sessions with good results. Conclusions: Zenker's endoscopic septotomy of the diverticulum is an effective and safe method; thereby it represents a real alternative to surgical treatment.

Application of pancreatic duct guide wire and transpancreatic septotomy with precutting techniques in dififcult endoscopic retrograde cholangiopancreatography / 中国内镜杂志

Objective To investigate the application value of pancreatic duct guide wire and transpancreatic septotomy with precutting technique in difficult endoscopic retrograde cholangiopancreatography.Method258 patients who underwent difficult endoscopic retrograde cholangiopancreatography from April 2014 to April 2016 were selected as study subject, 128 patients among them received the technique of pancreatic duct guide wire, the other 130 patients received transpancreatic septotomy with precutting techniques. The success rate, intubation time and incidence of complications were compared between these two methods for cannulation.Result There was no signiifcant difference in preoperative clinical data between the two groups, the success rate did not differ signiifcantly between the two groups (93.75 % vs 93.85 %). Compared with transpancreatic septotomy with precutting techniques group, pancreatic duct guide wire group is less intubation time consuming (5.92 ± 0.69 vs 12.81 ± 3.67) min, the difference was statistically significant (t = -2.27,P < 0.05). 25 patients experienced complications, with 6 cases of acute pancreatitis, 2 cases of biliray tract infection in pancreatic duct guide wire group, and 8 cases of acute pancreatitis, 3 cases of hemorrhage,6 cases of biliray tract infection in transpancreatic septotomy with precutting techniques group. The pancreatic duct guide wire group had a signiifcantly lower incidence of complications (6.25 % vs 13.08 %). the difference was statistically signiifcant (χ2 = 3.27,P < 0.05). The incidence of acute pancreatitis did not differ signiifcantly between the two groups (4.69 % vs 6.15 %).ConclusionsPancreatic duct guide wire and transpancreatic septotomy with precutting techniques both can further improve the success rate of bile duct cannulation with ERCP. The incidence of acute pancreatitis did not differ significantly between two groups. But pancreatic duct guide wire group is less intubation time consuming, and had a significantly lower incidence of complications. Because of the convenience and safety of the pancreatic duct guide wire technique, and the insertion of the pancreatic duct does not increase the risk of postoperative acute pancreatitis. We think that this method is more worthy of Clinical promotion.

Intramural Duodenal Hematoma after Transpancreatic Septotomy during ERCP: A Case Report and Literature Review / 대한췌담도학회지

Transpancreatic septotomy is known to improve the success rate of selective bile duct cannulation in endoscopic retrograde cholangiopancreatography. Recent retrospective study reported that transpancreatic septotomy is more effective and safer than needle knife sphincterotomy. Herein, we report a case of patient with gallstone pancreatitis who suffered from intramural duodenal hematoma after transpancreatic septotomy that caused obstruction of the duodenum and hypovolemic shock. The intramural hematoma improved after conservative management. The rare adverse event such as intramural duodenal hematoma seems to be considered after transpancreatic septotomy, especially when acute pancreatitis is accompanied.

Different Strategies for Transpancreatic Septotomy and Needle Knife Infundibulotomy Due to the Presence of Unintended Pancreatic Cannulation in Difficult Biliary Cannulation

BACKGROUND/AIMS: Several precut techniques have been used to gain biliary access for difficult cases. The aim of this study was to evaluate the success and complication rates of two precut techniques, transpancreatic septotomy (TPS) and needle knife infundibulotomy (NKI), in difficult biliary cannulation due to the presence of unintended pancreatic cannulation. METHODS: Eighty-six patients who failed standard biliary cannulation were included. TPS was performed when we failed to achieve biliary access despite 5 minutes of attempted cannulation or when more than three attempted unintended pancreatic cannulations occurred. If deep cannulation was not achieved within 5 minutes for any duct, NKI was performed. If this failed, we crossed over to the other technique in the second attempt. RESULTS: The initial total success rate of biliary cannulation was 88.4% (86.6% for the TPS group and 94.7% for the NKI group, p=0.447). After crossover of the techniques, the final success rate was 95.3%. The complication rate was 20.9% in patients with TPS and 15.8% in patients with NKI (p=0.753). CONCLUSIONS: The use of different strategies based on the presence of unintended pancreatic cannulation may help increase the success rate for difficult biliary cannulation without increasing complication rates.

Hysteroscopic Septotomy of a Complete Septate Uterus Using a Balloon with Methylene Blue / 대한불임학회지

A complete septate uterus with cervical duplication and a longitudinal vaginal septum is a rare uterine malformation. The dissection of the septum can be difficult because it is difficult for hysteroscopists to find out initial point, direction and final point of a complete septum. This study aimed the introduction of more efficient surgical procedure using a balloon with methylene blue. We have experienced three cases with a complete septate uterus. We performed hysteroscopic dissection of a complete uterine septum using a balloon with methylene blue and obtained good reproductive outcomes. So we report three cases with a brief review of literatures.

A variant of complete septate uterus with double cervix and vagina: A case report / 대한산부인과학회지

Rare mullerian anomalies without any present classification were sometimes reported. A 30-year-old nulligravid woman was referred to our hospital with 2-year history of primary infertility. Laparoscopic examination revealed a relatively intact uterine fundus with both patent fallopian tubes. Hysteroscopic exam confirmed the presence of double vagina and cervix, as well as complete uterine septum with opening at the lower segment. Hysteroscopic septotomy was successfully performed through the right-sided cervix. A variant of complete septate uterus with double cervix that communicated at the isthmic portion could be successfully treated by hysteroscopic operation.

Reproductive Outcome of Women with Recurrent Abortions or Infertility Following Treatment by Operative Hysteroscopy for an Intrauterine Septum / 대한산부인과학회잡지

Uterine anomalies have been reported in 4% of women with infertility and in up to 15% of those with recurrent abortion. One of the major intrauterine disorder associated with infertility and recurrent abortions is intrauterine septum, The reproductive outcome of 41 patients of intrauterine septum (7 complete, 34 incomplete) with repeated abortions or infertility was assessed after the uterine septotomy. 5 of 7 patients with comlete uterine septum undergone uterine septotomy (3; hysteroscopic metroplasty, 2; abdominal metroplasty) had total 6 pregnancies and all of them had live biths. 28 patients with incomplete uterine septum got the hysteroscopic intrauterine septotomy and the viable pregnancy rate was 62% (3 ongoing pregnancies, 13 live biths of total 26 pregnancies). 6 patients with incomplete uterine septum had not the operation and 5 patients had 5 live births after total 6 pregnancies with 1 spontaneus abortion. Even though, the number of cases were small, the live birth rate in the group of septotomy of the patients of complete uterine septum (100%, 6/6) was higher than that in the group of not-done (50%, 1/2). The live birth rate in the group of not-done of the patients with incomplete uterine septum (83%, 5/6) was higher than that in the group of hysteroscopic uterine septotomy (62%, 16/26), but 5 of 6 had short uterine septal length (<1 cm), 1 had 1.5 cm septal length in the group of not-done. All the patients with successful pregnancy outcome had no other co-factors at the diagnostic laparoscopy, but the 5 primary infertility patients with no live birth even after treatment (all were with incomplete septum; 3 undergone hysteroscopic septotomy, 2 not-done with one abortion) had other co-factors such as endometriosis, peritoneal or tubal facor. In conclusion, hysteroscopic uterine septotomy would be useful for the patients with habitutal abortion or infertility and more advanced managemnet protocols should be applied to the patients having other co-factors if there was no pregnancy even after the uterine septotomy.
