ABSTRACT
Objective:To evaluate the clinical efficacy of endoscopy for early cancer of duodenal papilla.Methods:A retrospective analysis was performed on data collected from 23 consecutive patients with early cancer of duodenal papilla, who underwent endoscopic treatment from January 2015 to January 2021 in Beijing Friendship Hospital. Baseline data, endoscopic and pathological data, occurrence and outcome of complications were studied.Results:Twenty-three patients successfully received endoscopic treatment. The maximal diameter of lesions evaluated under endoscopy was 1.90±0.83 cm. Among the 23 cases, 20 underwent endoscopic mucosal resection and 3 underwent endoscopic piecemeal mucosal resection. Delayed bleeding occurred in 5 cases (21.7%), 3 patients (13.0%) developed postoperative hyperamylasemia, 6 patients (26.1%) developed mild acute pancreatitis, and 1 patient (4.3%) had pancreatic duct stent displacement after the operation, which improved after medical or endoscopic treatment. No perforation occurred during the perioperative period. In terms of final pathology, the en bloc resection rate was 82.6% (19/23), and the complete resection rate was 78.3% (18/23). Preoperative endoscopic ultrasonography showed that 19 lesions were confined to the mucosal layer, which were all demonstrated by postoperative pathology. Four other cases were suspected to be involved in the submucosa or the end of the pancreaticobiliary duct under endoscopic ultrasonography, two of which were confined to the mucosal layer, and the other 2 cases involved the submucosal layer, so additional surgery was performed. A total of 18 patients were followed up, among whom 14 achieved complete resection of postoperative pathology, and 2 patients (14.3%, 2/14) were found to have recurrence at 12 and 51 months respectively after the treatment and did not relapse after surgical treatment and endoscopic treatment respectively. Among 4 other patients of follow-up whose pathology did not achieve complete resection, 1 had no recurrence, and the other 3 received additional surgical treatment without recurrence.Conclusion:Endoscopic treatment for early cancer of duodenal papilla is safe and effective. It is necessary to improve preoperative evaluation, stay alert to perioperative complications, and pay attention to regular postoperative endoscopic follow-up.
ABSTRACT
Objective:To study the effect of duodenal papillary morphology on selective biliary cannulation (SBC).Methods:Data of 912 patients with biliopancreatic diseases treated with endoscopic retrograde cholangiopancreatography (ERCP) at the Department of Gastroenterology, Affiliated Hospital of Northwest Minzu University from January 2018 to January 2020 were retrospectively analyzed. Duodenal papillary morphology of patients was classified into 4 types by using Haraldsson's endoscopic classification. The success rate of SBC, the pre-incision rate, the difficult intubation rate and the incidence of post-ERCP pancreatitis (PEP) of different papillary types were analyzed.Results:A total of 912 patients were enrolled in this study, and 86.95% (793/912) duodenal papilla conformed to one type of the classification, of which 77.18% (612/793) were regular type (type Ⅰ), 10.21% (81/793) small nipple type (type Ⅱ), 8.58% (68/793) protruding or drooping type (type Ⅲ), and 4.04% (32/793) wrinkled or ridged type (type Ⅳ). The success rates of SBC in four types of duodenal papilla were 98.86% (605/612), 90.12% (73/81), 88.24% (60/68) and 96.60% (28/32) respectively. The success rate of SBC of type Ⅰ was higher than those of type Ⅱ-Ⅳ (all P<0.008) and there was no significant difference between those of type Ⅱ and type Ⅲ ( P> 0.008). The pre-incision rate in the four types of duodenal papilla were 7.84% (48/612), 32.10% (26/81), 50.00% (34/68) and 25.00% (8/32) respectively. The pre-incision rate of type Ⅰ was lower than those of type Ⅱ-Ⅳ (all P<0.008), and there was no significant difference between those of type Ⅱ and type Ⅲ ( P>0.008). The difficult intubation rate in the four types of duodenal papilla were 12.42% (76/612), 39.51% (32/81), 58.82% (40/68) and 28.12% (9/32) respectively .The difficult intubation rate of type Ⅰ was lower than those of type Ⅱ and type Ⅲ (both P<0.001), and that of type Ⅲ was higher than that of type Ⅳ ( P=0.004) . There was no significant difference between those of type Ⅰ and type Ⅳ or type Ⅱ and type Ⅲ (both P>0.008). The incidences of PEP of the four types were 2.61% (16/612), 12.35% (10/81), 5.88% (4/68) and 6.25% (2/32) respectively. The incidences of PEP of type Ⅱ was higher than that of type Ⅰ ( P<0.001) , and there was no significant difference between those of type Ⅰ and type Ⅳ or type Ⅱ and type Ⅲ (both P>0.008). Conclusion:SBC is affected by duodenal papilla morphology, easiest for type Ⅰ and hard for type Ⅱ and Ⅲ. Attention should be paid to risk of PEP in SBC of type Ⅱ.
ABSTRACT
ABSTRACT BACKGROUND: Duodenal papilla neuroendocrine tumors (DP-NET) are rare. Surgical therapy may be recommended for their treatment. However, they have high rates of morbidity and mortality. Endoscopic papillectomy (EP) is safe and effective for complete resection of tumors at this site. OBJECTIVE: This study aimed to describe a case series of DP-NETs resected by EP and perform a literature review. METHODS: A series of patients with DP-NETs underwent EP as primary treatment between Jan/2008 and Mar/2020 at a tertiary referral center. A comprehensive search was made on the MEDLINE primary electronic database. The search strategy was designed to find all articles related to DP-NETs published in the literature. RESULTS: Six patients underwent EP for presenting DP-NETs, four of whom were women (mean age, 63 years). The mean diameter of DP-NETs was 1.6±0.3 cm. Four of six patients were followed up, one of whom suffered relapse at the resection site after 3 months and was referred to surgery (pT3n1b) and the remaining three patients experienced no endoscopic or histological recurrence during follow-up periods of 10, 7, and 4 years, respectively. Eighteen articles were found in the literature search in MEDLINE. The articles included case reports of endoscopically treated DP-NETs. CONCLUSION: EP is safe and effective for DP-NETs that are ≤20 mm, confined to the submucosal layer, well-differentiated, and without local or remote metastasis. Adequate endoscopic follow-up and definitive surgical treatment in the presence of relapse are necessary.
RESUMO CONTEXTO: Tumores neuroendócrinos da papila duodenal (TNE-PD) são raros. A cirurgia deve ser recomendada para o tratamento. No entanto, apresentam altas taxas de morbimortalidade. A papilectomia endoscópica (PE) é segura e eficaz para a ressecção completa de tumores nesta região. OBJETIVO: Descrever uma série de casos de TNEs-PD ressecados por PE e realizar uma revisão da literatura. MÉTODOS: Pacientes com TNEs-PD submetidos a PE como tratamento primário com intenção curativa entre jan/2008 e mar/2020 em um centro de referência terciário foram estudados. Uma pesquisa abrangente foi feita no MEDLINE. A estratégia de busca foi desenhada para encontrar todos os artigos relacionados a TNEs-PD publicados na literatura, que haviam sido submetidos a PE. RESULTADOS: Seis pacientes foram submetidos a PE por apresentar TNEs-PD, sendo quatro mulheres, com média de idade de 66 anos (22-96). O diâmetro médio dos TNEs-PD foi de 1,8±0,4 cm. Quatro dos seis pacientes foram acompanhados, um dos quais sofreu recidiva no local da ressecção após 3 meses e foi encaminhado para cirurgia (pT3n1b), e os três pacientes restantes não apresentaram recorrência endoscópica ou histológica durante os períodos de acompanhamento de 10, 7 e 4 anos, respectivamente. Dezoito artigos foram encontrados no MEDLINE. Os artigos incluíram relatos de casos de TNEs-PD tratados pela PE. CONCLUSÃO: A PE é segura e eficaz para TNEs-PD ≤20 mm, confinados à camada submucosa, bem diferenciados e sem metástases locais ou remotas. Acompanhamento endoscópico adequado e tratamento cirúrgico definitivo na vigência de recidiva são necessários.

Objective:To investigate the risk factors of duodenal papilla hemorrhage after endoscopic papillary balloon dilatation (EPBD) for choledocholithiasis.Methods:Clinical data of 411 cases of choledocholithiasis treated by EPBD in Hangzhou First People′s Hospital from January 2016 to December 2019 were analyzed retrospectively. Based on the development of hemorrhage after EPBD, patients were divided into the hemorrhage group and the non-hemorrhage group. The risk factors of hemorrhage after EPBD were analyzed by single and Logistic regression.Results:Among 411 patients who received EPBD, 29 patients had EPBD-related duodenal papilla hemorrhage and the overall incidence was 7.1%.Univariate analysis showed that there were significant differences between the hemorrhage group and the non-hemorrhage group in diameter≥1.2 cm of balloon dilation ( P=0.001), endoscopic sphincterotomy (EST) ( P=0.002)and the incision length of EST ( P<0.001). Logistic regression analysis showed that the incision length of EST ( OR=69.771, 95% CI: 7.544-645.296, P<0.001) was the independent risk factor for duodenal papilla hemorrhage after EPBD. Diameter≥1.2 cm of balloon dilation( OR=0.192, 95% CI: 0.071-0.524, P=0.001) was a protective factor. Conclusion:The incision length of EST is an independent risk factor of duodenal papilla hemorrhage after EPBD. Endoscopic papillary large balloon dilation is a protective factor for postoperative hemorrhage, which can reduce the incidence of bleeding.
ABSTRACT
Objective To evaluate the efficiency and safety of full-spectrum endoscopy for detection of major duodenal papilla. Methods Patients underwent painless gastroscopy in Chinese PLA General Hospital from March 2017 to December 2017 were enrolled and randomly divided into two groups according to random number method. The group A underwent conventional gastroscopy, and the group B underwent full-spectrum endoscopy. The detection rate of major duodenal papilla was calculated and compared between the two groups. Results A total of 100 patients were recruited in the study, including 51 in the group A and 49 in the group B. The whole detection rate of major duodenal papilla of the group B was higher than that of the group A [79. 59％ (39/49) VS 41. 18％ (21/51), χ2 =15. 366, P=0. 000]. There was no statistical difference on the whole plus partial detection rate of major duodenal papilla between the two groups [100. 00％ (49/49) VS 92. 16％ (47/51), χ2=2. 221, P=0. 136]. All patients completed endoscopy examination succesfully without bleeding, peforation or death. Conclusion With the broad view-field, full-spectrum endoscopy is useful to improve the efficiency and safety in detection of major duodenal papilla.
ABSTRACT
Introduction: Without the knowledge of the normal pattern of the duct system and its variations, a radiologistcan’t interpret an Endoscopic Retrograde Cholangiopancreatography (ERCP) picture. So it becomes important tostudy the anatomy of pancreatic ducts, their relation to each other, to common bile duct and to duodenum in theavailable human cadavers. The present paper is about the study of distance between minor and major duodenalpapilla from pylorus which was carried out on 96 cadaveric specimens of human duodeno-pancreas. To visualiseand to see distance between minor and major duodenal papillae is necessary for the endoscopist who aims toperform the dilation, stenting, or papillotomy of the minor papilla.Materials and Methods: The study was conducted in 96 (64 male and 32 female) cadavers. Major and minorduodenal papillae were visualized through eosin dye installation in both common bile duct and the accessorypancreatic duct. The measurement of distance between the duodenal papillae and to pylorus was done in cm.Results: In the present work, the mean ± SD of the Distance between pylorus to MAP is 8.05 ± 1.71 cm, pylorus toMIP is 6.19 ± 1.49 cm, the major to minor duodenal papilla was on an average 2.02 ± 0.40 cm, these distanceswere more in males as compared to females. But the size of Orifice of MAP in specimens is 7.25 ± 1.25 mm morein females as compared to males.Conclusion: The length of the duct shows sexual dimorphism; the length being more in males than females.
ABSTRACT
The accessory pancreatic duct is the smaller and less constant pancreatic duct in comparison with the mainpancreatic duct. We investigated the patency of the accessory pancreatic duct and its role in pancreaticpathophysiology. The present study was carried out in the department of Anatomy and forensic medicine, ACSRGovt. medical college, Nellore, Andhra Pradesh, India and in the department of Anatomy, RIMS, Ongole, AndhraPradesh, India. With 96 human cadavers (64 males and 32 females) with 30 to 80 years age group have beenstudied after obtained of ethical committee permission. The dissection method was followed to obtain specimenof pancreas along with C-loop of duodenum, papillae were identified ad dye was injected into APD to see itspatency at MIP. 93.75% specimens present MIP. The prevalence of patency of APD at MIP in population understudy was 38.89%; this is more in males was 43.33%, when compared to the females was 30% but this differencewas not significant statistically. It observed that out of 35 patent APD cases, 33 cases had inter papillarydistance either 2cm or more than 2cm. I t indicates 94.29% of patent APD cases had inter-papillary distancee”2cm. So there is strong relationship between APD patency and inter papillary distance in population understudy. The means inter-papillary distance in patent APD cases was 2.29 ± 0.2cm and non-patent APD cases was1.85 ± 0.25 cm. This difference was statistically significant.
ABSTRACT
Neuroendocrine tumor (NET) of the major duodenal papilla is a rare occurrence. However, that of the minor duodenal papilla is even rarer. To date, only a few cases have been reported. Herein, we present a rare case of NETs detected at the major and minor duodenal papilla synchronously, which were successfully treated with endoscopic papillectomy without procedure-related complication. To the best of our knowledge, this is the first report of this kind in the world. Photomicrograph of the biopsy specimen stained immunohistochemically for synaptophysin showed a positive reaction of tumor cells. All resection margins were negative. Further experience with more cases will be needed to establish the exact indication of endoscopic papillectomy for duodenal papillary NETs.

ABSTRACT
Objective To evaluate the efficacy and safety of double guidewire technique in perforation of duodenal papilla caused by guide wire during endoscopic retrograde cholangiopancreatography ( ERCP ) intubation. Methods A retrospective analysis was performed on data of 57 patients whose duodenal papilla were perforated by guidewire in ERCP from January 2008 to September 2016. Among the 57 patients, 30 patients were cannulated with double guidewire technique ( double guidewire group ) and 27 patients were performed with traditional technique ( standard group ) for continue. The biliary intubation success rate, intubation time, and post-ERCP complication rate were compared between the two groups. Results The rate of successful intubation of the double guidewire group was significantly higher than that of the standard group[96. 7％ (29/30) VS 74. 1％ (20/27),χ2=5. 545, P=0. 019]. The intubation time of the double guidewire group was significantly shorter than that of the standard group (21. 8±7. 8 min VS 40. 7 ±8. 4 min, t=8. 076, P=0. 000). The double guidewire group had a similar incidence of post-ERCP complication compared to the standard group[ 13. 3％ ( 4/30) VS 11. 1％ ( 3/27) ,χ2=0. 292, P=0. 596] , and the complication in two groups was hyperamylasemia. Conclusion Double guidewire technique is safe and effective for difficult biliary cannulation because of perforation of duodenal papilla with a higher success rate and less time compared to classic technique.
ABSTRACT
Objective To investigate the clinical characteristics of incarcerated stones at duodenal papilla and to evaluate the efficacy of endoscopic needle-knife sphincterotomy ( NKS ) . Methods Data of 316 patients who underwent endoscopic treatment for incarcerated stones at duodenal papilla between 2007 and 2016 were retrospectively studied. Endoscopic treatment outcomes, proportion changes of incarcerated stones in total number of choledocholithiasis, changes of diameter of common bile duct( CBD) and diameter of incarcerated stones were analyzed. Results Obstruction was relieved and endoscopic nasobiliary drainage was successfully performed in all 316 cases ( 100. 0％) , and NKS procedures were performed in 231 patients ( 73. 1％) . The incidence of incarcerated stone at duodenal papilla in choledocholithiasis showed a decreased trend ( P=0. 000) . Diameters of both CBD and incarcerated stones showed a decreased trend in hierarchical data by year ( P=0. 000, P=0. 000) . Conclusion The incidence of incarcerated stones at duodenal papilla in choledocholithiasis, the diameters of CBD and incarcerated stones are all on the decrease. NKS is the primary method for treatment of incarcerated stones at duodenal papilla.
ABSTRACT
Objective To evaluate the application value of emergency endoscopic needle-knife sphincterotomy(NKS) on acute cholangitis of severe type (ACST) resulting from impacted common bile duct stones at duodenal papilla. Methods A retrospective study was performed on the data of 90 ACST cases with impacted common bile duct stones at the native papilla and undergoing emergency NKS between January 2011 and January 2017 in Tianjin Nankai Hospital. The completion of treatment, mean operating time, impacted stone clearance rate, changes of laboratory indexes before and after endoscopic procedure, and complications were analyzed. Results All the 90 patients underwent emergency NKS successfully, with a total success rate of 100. 0％. The mean operating time was 25. 2±11. 7 min. The impacted stone clearance rate was 95. 6％(86/90). The complication rate was 5. 6％(5/90), including 3 cases of hemorrhage and 2 cases of post-ERCP pancreatitis. There was no procedure-related mortality. The postoperative white blood cell count, serum procalcitonin, total bilirubin, direct bilirubin, and glutamic-pyruvic transaminase decreased significantly compared with pre-operation ( all P<0. 001) . Conclusion Emergency NKS is effective and safe for treatment of ACST resulting from impacted common bile duct stones at duodenal papilla with a relative high application value.
ABSTRACT
Objective To investigate the risk factors and countermeasures for endoscopic retrograde cholangiopancreatography (ERCP) related duodenal papilla hemorrhage. Methods Retrospective analysis was performed on the clinical data of 890 patients who underwent ERCP. According to whether the patients with ERCP related duodenal papilla hemorrhage, they were divided into the hemorrhage group and the non hemorrhage group. And the risk factors of duodenal papilla hemorrhage and their countermeasures were investigated. Results 51 patients had ERCP related duodenal papilla hemorrhage, and the overall incidence rate was 5.7%. Compared with the non hemorrhage group, the patients proportion of common bile duct stones was lower, but the cholangiocarcinoma and pancreatic head cancer were higher in the hemorrhage group (P < 0.05). The incidence of hypertension and duodenal diverticulum in the hemorrhage group were significantly higher than that in the non hemorrhage group (P < 0.05). Subgroup analysis showed that patients with stone diameter >2 cm, stone incarceration and the duodenal papilla into diverticulum in the hemorrhage group were significantly higher than that in the non hemorrhage group (P < 0.05). Conclusion Common bile duct stone diameter >2 cm, stone incarceration, malignant biliary and pancreatic cancer, hypertension and duodenal papilla into diverticulum were objective risk factors of ERCP related duodenal papilla hemorrhage, focus on prevention of bleeding. Endoscopic hemostasis was safe and effective.
ABSTRACT
Objective:To evaluate the prognostic factors for duodenalpapilla carcinoma (DPC)treated by pancreatoduodenectomy (PD).Methods:Clinicopathological data of 68 patients with duodenalpapilla carcinoma who undergone PD and finally diagnosed by surgery and histopathology from January 2001 to June 2010 were retrospectively analyzed.The patients were followed-up until 2015.Survival analysis was conducted using the Kaplan-Meier survival and Cox proportional hazards model analysis.The difference in survival curves was evaluated with a log-rank test.Results:The patients were followed-up with a median follow-up of 57 months (ranging from 4 months to 168 months).The univariate analysis showed that increased serum levels of total bilirubin were correlated with a poor prognosis,as well as a senior grade of infiltration depth,lymph node metastases,and TNM stage (P=0.043,0.003,0.004 0.002,respectively).Only increased serum levels of total bilirubin and a senior grade of TNM stage retained their significance when adjustments were made for other known prognostic factors in Cox multivariate analysis (RR=2.031,P=0.031 and RR=2.255,P=0.029).Conclusions:Increased serum levels of total bilirubin were correlated with a poor prognosis,as well as a senior grade of infiltration depth,lymph node metastases,and TNM stage.Only increased serum levels of total bilirubin and a senior grade of TNM stage can serve as independent prognosis indexes in the evaluation of patients with DPC after PD.

ABSTRACT
Los tumores duodenales son menos frecuentes que los del estómago y colon. Los habituales son los carcinomas, linfomas y tumores de los estromas malignos o benignos; los pólipos duodenales suelen ser asintomáticos. Su manifestación más frecuente es la hemorragia. Las lesiones de gran tamaño pueden cursar con un cuadro suboclusivo y las periampulares producir ictericia. Se presentó el caso de una paciente de 68 años de edad, colecistectomizada que ingresa por íctero intermitente, con episodios de coluria, acolia, prurito generalizado, pérdida de peso y dolor en epigastrio, se realizó ecografía de hígado, vías biliares y páncreas en la cual se evidenció dilatación de vías biliares, se exploró endoscópicamente el duodeno y se observó una lesión sobreelevada se le realizó biopsia, diagnosticándose un adenoma de papila duodenal. La paciente fue sometida a una ampulectomía, no se observó focos de adenocarcinoma en la biopsia quirúrgica y el cuadro ictérico desapareció, no se presentaron complicaciones postoperatorias.
Duodenal tumors are less frequently than those of stomach and colon. The habitual ones are carcinomas, lymphomas and malignant or bening stromal tumors, duodenal polyps are usually asymptomatic. The haemorraghe is the most frequent sign. The great size lesions can show a suboclussive presentation and the periampullary ones can produce. A 68-year-old female patient to whom cholecystectomy was performed was presented in this article. The patient was admitted due to recurrent jaundice, episodes of dark urine, acholia, generalized pruritus, weight loss and epigastric pain. Ultrasonography of the liver, biliary tract and pancreas was performed in which bile duct dilatation was evident, duodenum was also explored and a lesion was observed. Biopsy was done and an adenoma of duodenal papilla was diagnosed. Surgical ampulectomy was performed without adenocarcinoma findings in the surgical biopsy, the jaundice disappeared and none postsurgical complication was observed.
ABSTRACT
Neuroendocrine tumors (NET) of the major duodenal papilla are rare and the natural history of this disease is not clear. We experienced a case in a 31-year-old male. Duodenoscopy revealed an enlarged major duodenal papilla with central umbilication and nodularity. Endoscopic ultrasonography (EUS) demonstrated a 3-cm hypoechoic mass that was confined to the submucosa. A biopsy led to the diagnosis of a grade 1 NET. The patient refused surgery, so we performed an endoscopic papillectomy. The tumor was removed completely. The resected specimen confirmed the diagnosis of a well-differentiated NET and all resection margins were negative. Surgical resection is currently considered to be the gold standard for the treatment of a large NET of the major duodenal papilla; however, endoscopic resection is a possible treatment modality for patients at high surgical risk or who are reluctant to undergo surgery.

Objective To study the therapeutic value of the endoscopic papillectomy for adenoma in the major duodenal papilla.Methods All 3 1 cases with the major duodenal papilla undergoing endoscopic papillectomy from January 2008 to June 2013 were retrospectively reviewed.The clinical data,endoscopic treatment,complications and follow-up were analysed.Results Endoscopic papillectomy was performed successfully in 29 patients.Post-operative pathology showed adenoma with low-grade dysplasia in 25 cases and high-grade dysplasia in 4 cases.One patient (3. 4%,1/29 )bled during operation;and there was no bleeding after operation. There was no perforation during and after the operation. Seventeen patients (58. 6%,17/29)developed hyperamylasemia and 3 patients(10. 3%,3/29)got mild pancreatitis,which were cured by conservative treatment.During follow-up,2 patients (6. 9%,2/29)with high-grade dysplasia had tumor recurrence after 6 months and 2 years respectively.The 27 other patients had no recurrence during the follow-up period.The shortest follow-up was 1 1 months,the longest was 5 years,with a mean time of 33. 5 ±8. 5 months.Conclusion Endoscopic papillectomy is feasible and safe for early tumors of the major duodenal papilla.Although the postoperative recurrence rate is low,it still needs close follow-up.
