Perforation is the rarest complication of duodenal diverticulum but also one of its most serious complications. Mortality rate was reported to up to 30%. Clinical diagnosis is usually vague and non-specific. High clinical suspicion is important as rapid deterioration is likely. Consensus regarding management is lacking and currently guided by a small series of case reviews. Surgical treatment is historically the standard therapeutic option. However, more current literature suggests improvement in patients with non-surgical management. In this paper, we discuss a case of a patient in her early 60s who had a perforated duodenal diverticulum that was treated conservatively. It highlights the importance of a good history and a CT scan to help with diagnosis. Close clinical observation is essential to detect disease progression. A step-up approach to clinical deterioration with either percutaneous drainage or surgical management should be considered if the patient does not respond to conservative treatment., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Most duodenal diverticula (DD) are asymptomatic and rarely develop perforations. Perforation is the most serious complication of DD and often requires emergency surgery. A 97-year-old woman who had undergone total gastrectomy and Roux-en-Y reconstruction 30 years ago was referred to our department with chief complaints of abdominal pain and fever during her hospitalization after femoral neck fracture surgery in the orthopedic department. Contrast-enhanced computed tomography showed free air and residue in the abdominal cavity and right retroperitoneum, and an emergency laparotomy was performed. The abdominal cavity was mildly contaminated, and a 6-cm DD with a 1-cm perforation in the wall of the diverticulum on the contralateral side of the mesentery of the duodenum was found. Diverticulectomy and duodenal closure were performed and a drainage tube was placed. The patient experienced no complications and was transferred to the orthopedic department on postoperative day 10. Reports of perforation of DD after gastrectomy are very rare. Particular attention should be paid to perforation of DD after Billroth-II and Roux-en-Y reconstructions as they involve the formation of a duodenal stump that differs from the normal anatomy and may be highly invasive surgical procedures, depending on the degree of inflammation and fistula formation., (© 2024.

Hayashi and colleagues developed a novel salvage technique using a cap-fitted ultrathin endoscope to cannulate the bile duct when a papilla concealed within a duodenal diverticulum is inaccessible with conventional methods. It can be a useful and safe option for endoscopic retrograde cholangiopancreatography in patients with papillae hidden in duodenal diverticula., (© 2024 Japanese Society of Hepato‐Biliary‐Pancreatic Surgery.)

The duodenum is the second most common location for a diverticulum to form after the colon. These duodenal diverticula (DD) are often found incidentally and rarely require intervention. In recent years, surgical management has been restricted to patients with significant complicated sequelae, such as perforation, abscess, or fistula formation. We present the rare case of a perforated broad-based diverticulum in the third portion of the duodenum necessitating surgical correction. The patient presented with persistent symptoms following failure of conservative management and underwent surgical resection. Due to difficulty visualizing the extent of the diverticulum, a novel intraoperative technique of bowel insufflation via nasogastric tube was used allowing for elucidation of the diverticular borders and complete resection. Although DD are common, there exists no consensus on when operative intervention is indicated. Given that significant morbidity and mortality can be associated with symptomatic DD, a systematic way to guide management decisions is needed. After conducting a review of the literature, we propose that the modified Hinchey classification can be used not only to categorize duodenal diverticulitis but to guide treatment choice in cases with unclear risk benefit profiles.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) for patients with periampullary diverticulum (PAD) remains a challenge. This study aims to investigate the factors and techniques related to successful and safe ERCP in patients with PAD., Methods: We enrolled patients who underwent ERCP in a large tertiary center. The difficult cannulation rate, technical success rate, clinical success rate, and adverse events (AEs) rate were compared between patients with or without PAD. Three independent logistic regression models were established to identify factors and techniques associated with difficult cannulation, clinical success, and AEs., Results: Five thousand five hundred and ninety patients were included, of which 705 (12.6%) were diagnosed with PAD. Patients with PAD had a significantly higher difficult cannulation rate compared with patients without PAD (10.6% vs 8.0%, P < 0.0001), but the rates of technical success (clinical success (95.2% vs 95.2%, P = 0.951), and AEs (16.5% vs 14.4%, P = 0.156) were similar. Type I PAD (odds ratio [OR] = 2.114, 95% confidence interval [CI]:1.05-5.25) and ERCP indication for pancreatic diseases (OR = 1.196, 95%CI: 1.053-1.261) were independently associated with difficult cannulation. Small endoscopic sphincterotomy (EST) with balloon dilatation (OR = 1.581, 95%CI: 1.044-2.393) was independently associated with clinical success. Somatostatin injection showed no preventive effect on post-ERCP pancreatitis (OR = 1.144, 95%CI: 1.044-1.254). Moreover, the auxiliary cannulation techniques were safe for PAD patients., Conclusions: PAD did not affect ERCP outcomes. However, the choice of techniques and AE prophylactic measures should be more specific, especially for patients with type I PAD., Competing Interests: None

Background: The perforated duodenal diverticulum remains a rare clinical entity, the optimal management of which has not been well established. Historically, primary surgery has been the preferred treatment modality. This was called into question during the last decade, with the successful application of non-operative therapy in selected patients. The aim of this systematic review is to identify cases of perforated duodenal diverticula published over the past decade and to assess any subsequent evolution in treatment., Methods: A systematic review of English and non-English articles reporting on perforated duodenal diverticula using MEDLINE (2008-2020) was performed. Only cases of perforated duodenal diverticula in adults (> 18 years) that reported on diagnosis and treatment were included., Results: Some 328 studies were identified, of which 31 articles met the inclusion criteria. These studies included a total of 47 patients with perforated duodenal diverticula. This series suggests a trend towards conservative management with 34% (16/47) of patients managed non-operatively. In 31% (5/16) patients initially managed conservatively, a step-up approach to surgical intervention was required., Conclusion: Conservative treatment of perforated duodenal diverticula appears to be an acceptable and safe treatment strategy in stable patients without signs of peritonitis under careful observation. For patients who fail to respond to conservative treatment, a step-up approach to percutaneous drainage or surgery can be applied. If surgery is required, competence in techniques ranging from simple diverticulectomy to Roux-en-Y gastric diversion or even Whipple's procedure may be required depending on tissue friability and diverticular collar size., (© 2021.

A man in his 70s visited our hospital for abdominal pain. Upon admission, abdominal computed tomography findings suggested a duodenal diverticular perforation. Upper gastrointestinal endoscopy revealed an incarcerated enterolith in the periampullary diverticulum. We achieved conservative management by inserting an endoscopic nasobiliary drainage tube into the duodenal diverticulum to aid drainage. The patient was discharged without serious complications 35 days after admission. We report a case of duodenal diverticular perforation with an incarcerated enterolith managed conservatively using endoscopic therapy.

Background: Endoscopic negative pressure therapy is a novel and successful treatment method for a variety of gastrointestinal leaks. This therapy mode has been frequently described for rectal and esophageal leakages. Duodenal diverticular perforations are rare but life-threatening events. The early diagnosis of duodenal diverticular perforation is often complicated by inconclusive symptoms. This is the first report about endoscopic negative pressure therapy in patients with perforated duodenal diverticula., Case Presentation: We present two cases of duodenal diverticula perforations treated with endoscopic negative pressure therapy as stand-alone treatment. Start of symptoms varied from one to three days before hospital admission. Early sectional imaging led to the diagnosis of duodenal diverticular perforation. Both patients were treated with endoluminal endoscopic negative pressure therapy with simultaneous feeding option. Three respective changes of the suction device were performed. Both patients were treated with antibiotics and antimycotics during their hospital stay and be discharged from hospital after 20 days., Conclusions: This is the first description of successful stand-alone treatment by endoscopic negative pressure therapy in two patients with perforated duodenal diverticulum. We thus strongly recommend to attempt interventional therapy with endoluminal endoscopic negative pressure therapy in patients with duodenal diverticular perforations upfront to surgery., (© 2021.

The duodenum is the second most common location of intestinal diverticula. Periampullary duodenal diverticulum rarely causes obstructive jaundice and this condition was first described by German surgeon Gerhard Lemmel in 1934. Lemmel's syndrome is defined as obstructive jaundice due to a periampullary duodenal diverticulum in the absence of choledocholithiasis or a neoplasm.

Background: The duodenal intussusception is rarely reported and usually occurs secondary to organic diseases of the duodenum such as polyps, tumors and duplication cysts. Herein we report a case of duodenal intussusception caused by duodenal diverticulum., Case Presentation: A 21-year old male patient presented with abdominal pain and vomiting for one day. A contrast enhanced computed tomography of the abdomen revealed duodenal intussusception. On emergency laparotomy, the intussusception had reduced spontaneously while an invaginated diverticulum was seen at the junction of the descending and horizontal segments of the duodenum. The diverticulum was resected and the patient had uneventful recovery., Conclusion: Duodenal intussusception is a rare complication of duodenal diverticulum. Being aware of this complication of diverticulum can help in timely diagnosis and treatment.

Background: Different types of periampullary diverticulum (PAD) may differentially affect the success of endoscopic retrograde cholangiopancreatography (ERCP) cannulation, but the clinical significance of the two current PAD classifications for cannulation is limited., Aim: To verify the clinical value of our newly proposed PAD classification., Methods: A new PAD classification (Li-Tanaka classification) was proposed at our center. All PAD patients with native papillae who underwent ERCP from January 2012 to December 2017 were classified according to three classification systems, and the effects of various types of PAD on ERCP cannulation were compared., Results: A total of 3564 patients with native papillae were enrolled, including 967 (27.13%) PAD patients and 2597 (72.87%) non-PAD patients. In the Li-Tanaka classification, type I PAD patients exhibited the highest difficult cannulation rate (23.1%, P = 0.01), and type II and IV patients had the highest cannulation success rates (99.4% in type II and 99.3% in type IV, P < 0.001). In a multivariable-adjusted logistic model, the overall successful cannulation rate in PAD patients was higher than that in non-PAD patients [odds ratio (OR) = 1.87, 95% confidence interval (CI): 1.04-3037, P = 0.037]. In addition, compared to the non-PAD group, the difficulty of cannulation in the type I PAD group according to the Li-Tanaka classification was greater (OR = 2.04, 95%CI: 1.13-3.68, P = 0.004), and the successful cannulation rate was lower (OR = 0.27, 95%CI: 0.11-0.66, P < 0.001), while it was higher in the type II PAD group (OR = 4.44, 95%CI: 1.61-12.29, P < 0.01)., Conclusion: Among the three PAD classifications, the Li-Tanaka classification has an obvious clinical advantage for ERCP cannulation, and it is helpful for evaluating potentially difficult and successful cannulation cases among different types of PAD patients., Competing Interests: Conflict-of-interest statement: The authors declare that they have no conflicts of interest to disclose., (©The Author(s) 2020.

We describe the case a 92-year-old woman who was admitted to our hospital with choledocholithiasis and periampullary diverticulum (PAD). Due to PAD, clear visualization of the ampulla of Vater could not be obtained. Although selective bile duct cannulation was difficult, a 7-Fr plastic stent was placed during the first session. Fifteen days later, endoscopic retrograde cholangiopancreatography was retried using traction devices, and the papilla became visible. Endoscopic sphincterotomy and stone extraction were performed without any complications. The application of traction devices in endoscopic submucosal dissection may be a promising technique in cases in which endoscopic biliary intervention is difficult due to PAD.

Lemmel's syndrome is a very rare condition as a cause of obstructive jaundice secondary to the presence of a duodenal diverticulum. We report a case, a 68-year-old female patient with a cholestatic pattern, biliary tract dilatation, who underwent ERCP, with a juxtapapillary diverticulum compressing the distal bile duct, which was sphincterotomy.

Background: Bleedings such as melaena are related to diseases in the upper gastrointestinal tract. In 0.06% - 5% of cases these incidents are due to the presence of diverticula of the small intestine, which are asymptomatic and unrecognized in most patients and are only fully diagnosed in cases when complications occur., Case Report: An 88-year old male patient presented with severe anaemia, asthenia and melaena in the previous days. An esophagogastroduodenoscopy (EGDS) was performed with evidence of stenosis in the second part of the duodenum and a blood clot in the posterior wall without signs of active bleeding. A complete CT scan was carried out of the thorax, abdomen and pelvis using a contrast medium, which revealed a dilation of the stomach and of the first part of the duodenum with a diverticulum of the second. On the fourth day following admission the patient suffered a haemorrhagic shock and underwent an emergency surgical procedure with a bleeding diverticulum on the posterior wall of the duodenum tightly adhering to the pancreas being found. Therefore an atypical duodenal-jejunal resection was performed using a gastrojejunal Roux-en-Y bypass and the closure of the duodenal stump., Conclusion: Diverticulosis of the duodenum and small intestine is considered a rare disease. According to the literature, treatment should be conservative, and surgical options considered only in those very rare cases of complicated and life-threatening diverticulosis.

Purpose: To investigate whether the 2-devices-in-1-channel method is useful for selective biliary cannulation in patients with parapapillary diverticulum or intradiverticular papilla, where the papilla cannot be seen from the front., Materials and Methods: Biliary cannulation using the 2-devices-in-1-channel method was performed in 28 patients who presented difficulty due to parapapillary diverticulum or intradiverticular papilla. There were 15 men and 13 women whose mean age was 68.8 (58 to 88) years. There were 22 patients with common bile duct stones, 5 with pancreatic cancer, and 1 with gallbladder cancer., Results: Selective biliary cannulation was successful in all 28 patients. Common bile duct stones could be removed in all 22 patients after endoscopic sphincterotomy or endoscopic balloon dilation, and all 5 patients with pancreatic cancer as well as the patient with gallbladder cancer were successfully drained. There were no procedure-related complications., Conclusions: From these results, we consider the 2-devices-in-1-channel method is useful and safe to perform selective biliary cannulation when the papilla cannot be seen from the front due to parapapillary diverticulum, or intradiverticular papilla.

Background: The use of needle-knife fistulotomy technique in patient with periampullary diverticula (PAD) for biliary duct cannulation may lead to risk of complications. The present study aimed to investigate the association between PAD and the complications of endoscopic retrograde cholangiopancreatography (ERCP), unsuccessful cannulation rates and to determine the rates of cannulation complications using sphincterotomy and needle-knife fistulotomy., Materials and Methods: The ERCP procedures were held in Gastroenterology Endoscopy Unit between September 2015 and October 2016 and were retrospectively evaluated. The patients were divided into two groups, a PAD group and a non-PAD group. These groups were compared regarding demographic characteristics, ERCP complications and mortality., Results: A total of 827 patients fulfilling the criteria for ERCP were enrolled in the study. Of 827 patients, 164 had PAD and 663 did not have PAD (non-PAD). The success rate of cannulation was 98.8% in patients with PAD and 98.6% in patients without PAD. There was no statistical difference of cannulation types with sphincterotomy and with needle-knife fistulotomy between the two groups. Mean baseline number of guide wire cannulation attempts was 1.96±0.20 in PAD group. No complications were observed in PAD patients treated with needle-knife fistulotomy. ERCP-related complications rates (bleeding, pancreatitis, and perforation) were higher in the PAD group (P=0.007)., Conclusion: In conclusion, there is a strong association between PAD and higher rates of cannulation complications, independent of cannulation technique. In certain situations, and in the hands of experienced endoscopists, needle-knife fistulotomy might be a feasible option for successful biliary cannulation in certain patients with PAD.

We present the case of an 82-year-old man with a history of heart failure, mitral regurgitation, type 2 DM, hypertension, dilated cardiomyopathy and a paroxysmal atrial flutter. The patient was under treatment with Sintrom. The patient presented to the emergency department due to melenic depositions of a one day evolution and dietary vomiting. There was no rectal bleeding and the patient was admitted three months previously due to self-limited melena with a normal gastroscopy. Anemia of 8 g and an overdose of Sintrom was diagnosed. A gastroscopy was performed and a large duodenal diverticulum with a fresh clot was found that was washed. A Dieulafoy lesion was subsequently found underneath with jet bleeding, which was sclerotic with adrenaline and a hemoclip. There was a favorable evolution after correcting the coagulopathy.

The authors present a rare case of perforated duodenal diverticulum diagnosed in an 80-year-old Caucasian woman with vomiting and abdominal pain localised to the epigastrium. CT scan showed thickening of the second portion of the duodenum with retroperitoneal fat stranding and perihepatic free fluid, with a presumptive diagnosis of a duodenal perforation. A laparotomy was performed which showed a perforated diverticulum in the second portion of the duodenum. A diverticulectomy with single-layer closure was performed, without complications. The postoperative course was uneventful., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

A 64-year-old man underwent abdominal computed tomography (CT) as periodic follow-up following a distal gastrectomy with lymphadenectomy for gastric cancer and mucosal-associated lymphoid tissue (MALT) lymphoma conducted 31 months earlier. Contrast-enhanced CT demonstrated a well-circumscribed mass lesion with heterogeneous density measuring 2.2 cm in diameter located between the second segment of the duodenum and uncinate process of the pancreas. Esophagogastroduodenoscopy revealed no remarkable findings in the remnant stomach; however, the scope could not reach the duodenum due to altered anatomy by Roux-en-Y reconstruction after the distal gastrectomy. The patient underwent surgical resection of the mass lesion under the clinical diagnosis of MALT lymphoma relapse. An orange calculus was apparent in the thinly extended duodenal wall on stretching, and the hall was closed by meticulous primary suture after the duodenal resection. Macroscopically, the extracted calculus was solid and quite hard, measured 2.2 × 2.1 × 2.1 cm, and the cut surface revealed a layered structure in the outer areas with granulated contents in the center. Although duodenal diverticula are relatively common, an enterolith developing within a juxtapapillary duodenal diverticulum is rare, and to the best of our knowledge, this is the first such case due to altered anatomy after gastrectomy reported in the English literature.

Periampullary duodenal diverticula are associated with the presence of common bile duct stones, being encountered more frequently with the increase of age. We present the case of a 76 years old female patient, who underwents emergency surgery for a perforated lithiasic gangrenous acute cholecystitis and for whom we perform a cholecystectomy and an external biliary drainage using a transcystic tube. Both preoperative and postoperative imaging and endoscopic examinations certify the presence of a periampullary duodenal diverticulum. Postoperative cholangiography performed on the transcystic tube raises the suspicion of retained common bile duct lithiasis. An endoscopic retrograde cholangiopancreatography is performed, initially failing to cannulate the common bile duct. A precut sphincterotomy fistula technnique is performed, using as reference a guide inserted on the transcystic tube, with the extraction of biliay sludge from the common bile duct, and with subsequently favorable development. Association between common bile duct lithiasis and a periampullary duodenal diverticulum may represent a therapeutic challenge because of the increased risk of failure of the endoscopic treatment., (Celsius.)

Unlabelled: Juxtapapillary duodenal diverticula are reported as a potential cause of many pancreatobiliary diseases. However, data concerning this association is inconsistent and the role of the diverticulum is often underestimated or even denied in clinical practice. This case report and literature review is aimed at pointing out this problem.Obstruction of the diverticulum with a food bezoar can be considered as an important clinical clue of the etiological role of the diverticulum in pancreatobiliary disease development.Endoscopic sphincterotomy is considered to be the treatment of the first choice, with surgery (diverticulectomy and/or biliodigestive anastomosis) reserved for cases where the minimally invasive approach fails., Key Words: juxtapapillary duodenal diverticulum obstructive jaundice acute pancreatitis endoscopic papilosphincterotomy biliodigestive anastomosis.

Basis and Purpose: The presence of peripapillary diverticulum (PPD) can cause some biliary diseases, especially common bile duct stones, and also, literally, can change the technique of endoscopic retrograde cholangiopancreatography (ERCP) and affect the complication ratio of this procedure. In this study, we investigate the effect of localization and position of the papilla according to the diverticulum on the success of therapeutic ERCP procedures., Materials and Methods: The study was conducted prospectively in the patients with naive papillae, who underwent ERCP for a period of 16 months. In all patients, the position of papillae according to the diverticulum (the periphery of the diverticulum is thought as the clock circumference, and the position of papillae is defined as the dials of clock), the success rate of biliary cannulation, total procedure time, overall treatment success rate of ERCP, and the complications are investigated., Results: During this period, 222 (18.5%) of the 1205 enrolled patients who underwent ERCP had PPD. Of the patients with PPD, 123 (55.4%) were female and 99 (44.6%) were male, and the median age was 68.9±10.1 years. According to the position of the papilla by the diverticulum, 90 (40.5%) patients have it on 7 o'clock position, 64 (28.8%) patients have on 6 o'clock position, 63 (28.3%) patients have on 5 o'clock position, and 5 (2.3%) patients have on 1 o'clock position. In the cases of the papilla on 1 o'clock position according to the diverticulum, cannulation procedures were found to be more difficult than other patients (P<0.05). The presence of the diverticulum did not affect the success of therapeutic procedures and did not increase the ratio of complications., Conclusions: In the presence of PPD, additional cannulation techniques may be required for the procedure. Particularly, the aid of percutaneous techniques may be needed for the papilla on 1 o'clock position.

Duodenal diverticula are common, but perforated duodenal diverticulum is rare. Because of the disease rarity, there is no standard management protocol for perforated duodenal diverticulum. To properly manage this rare complication, a clear preoperative diagnosis and clinical disease severity assessment are important. An abdomino-pelvic CT is an unquestionably crucial diagnostic tool. Perforation is considered a surgical emergency, although conservative treatment based on fasting and broad-spectrum antibiotics may be offered in some selected cases. Herein, we report two cases of perforated duodenal diverticulum, one case managed with surgical treatment and one with conservative treatment.

Duodenal diverticula are relatively common and usually asymptomatic (95%). Their perforation is a rare but harmful event. Traumatic perforation is exceptional. We report the case of a patient with such a lesion following a blunt trauma secondary to a car accident, and review the literature. Clinical presentation is aspecific and diagnosis is based upon CT scan imaging. Surgery is the recommended treatment consisting of diverticulectomy with transverse duodenal closure of the duodenum associated with retroperitoneal drainage., (Copyright© Acta Chirurgica Belgica.)

Background: Previous studies have evaluated the presence of juxtapapillary duodenal diverticula (JPDD) and the association with pancreatobiliary disease, but not the association of the papilla with an existing JPDD. We investigated the association of different localizations of the papilla with JPDD., Methods: We studied patients in whom JPDD was detected during endoscopic retrograde cholangiopancreatography. Patients were classified into 3 groups: 1) papilla located inside the diverticulum, 2) papilla located at the edge of the diverticulum and 3) papilla located closer than 3 cm to the diverticulum. The patients were examined with respect to localization of papilla-diverticula and to the association of the localization with pancreaticobiliary disease., Results: We enrolled 274 patients in our study. Biliary stone disease more frequently existed in group 3. The number of patients presenting with obstructive jaundice was higher in groups 2 (83.6%) and 3 (83.3%) than group 1 (66%). Cholangitis was more common in group 1 (21.3%) than in groups 2 (6.7%) and 3 (2.3%). The presence of biliary stone disease among patients presenting with pancreatitis was significantly different between groups 1 and 3 (p = 0.013) and between groups 2 and 3 (p = 0.017). The common bile duct more frequently contained stones or sludge in group 3 than in groups 1 and 2., Conclusion: When the papilla is located close to the JPDD, the incidence of biliary stone disease decreases, and pancreatobiliary diseases are caused mostly in the absence of biliary stone disease.

We present the case of a 78-year-old woman who was admitted for an elective left hemicolectomy for diverticular disease. Two days following the elective procedure, bilious fluid was noted in her pelvic drain. The patient returned to theatre, where a perforated duodenal diverticulum was excised and the defect primarily repaired. The patient then developed a low output enterocutaneous fistula which was treated conservatively with nasojejunal feeding and resolved spontaneously., (2014 BMJ Publishing Group Ltd.)

We herein describe that a Roux-en-Y duodenojejunostomy is a simple and secure procedure for perforated diverticulum in the second portion of the duodenum. The surgical technique for perforated duodenal diverticulum can be adaptable when it is difficult to achieve closure of the perforated site easily. Patients who undergo the operation may be able to eat meals, even if duodenal fistula occurs in the postoperative course.

The successful management of upper gastrointestinal (GI) bleeding requires identification of the source of bleeding and when this is achieved the bleeding can often be treated endoscopically. However, the identification of the bleeding can be challenging due to the location of the bleeding or technical aspects. Therefore it might be necessary to use other measures than endoscopy such as CT angiography. Duodenal diverticula is a rare cause of upper GI bleeding and can be challenging to diagnose as they often require specialised endoscopy procedures such as endoscopy with a side-viewing scope. This case describes the first successful management of this rare condition with an upper GI endoscopy with a colonoscope and afterwards intravascular coiling., (2014 BMJ Publishing Group Ltd.)

Background and Aim: Periampullary diverticula (PAD) are found in 9-32% of patients who undergo endoscopic retrograde cholangiopancreatography (ERCP). PAD are acquired lesions which are rare in patients <40 years, but increasing with age. Several endoscopic studies have revealed an association between PAD and common bile duct (CBD) stones. The presence of a papilla located in the diverticula is also frequent (6.8-54.9%) and represents a restrictive factor for successful cannulation., Materials and Methods: A retrospective analysis has been made of data related to the patients with PAD treated at our GI Unit (small center with low case volume), who underwent ERCP in the period 1st January 2010 to 31st March 2014. For each patient were analyzed data regarding sex, age at diagnosis, indication to ERCP, cannulation rate, endoscopic treatment and complications. PAD were classified in 3 different types according to the position of the major papilla., Results: A total of 647 ERCPs have been performed of which 77 (16.5%) in pts with PAD (48 F, 29 M, mean age: 78.3 years; range: 48-95). PAD type I (inside the diverticulum) were found in 22 pts (28.6 %), Type II (in the margin of the diverticulum or between two PADs) in 36 pts (46.7 %) of which 12 cases between two PADs, type III (near the diverticulm) in 19 pts (24.7 %). The indication for ERCP were: 72 CBD stones (93.5%), 3 cholangiocarcinoma (3.9%) and 2 pancreatic head cancer (2.6%). In cases of difficult cannulation, precut was performed in 12 pts (15.6%). Deep CBD cannulation and endoscopic sphincterotomy (ES) was achieved in 70 cases (90.9%). The other 7 case of failure were all in patients with CBD stones. Complete clearance of CBD stones was achieved in 57 patients (87.7%) (57/65 ERCP/ES). Stent placement was necessary in 8 cases (12.3%) (8/65 ERCP/ES), due to multiple large stones. The adverse events related to ERCP/ES included 4 intraprocedural bleeding (5.7%) (4/70 ERCP/ES) and 1 mild pancreatitis (1.4%) (1/70 ERCP/ES), all managed conservatively., Conclusions: Our data show that ERCP is a safe procedure also in patients with PAD, with a good success rate and low complications.

Background: the presence of duodenal diverticula was first described in 1710 by Chromel. Duodenal diverticulum is the second most common site of diverticula in the digestive tract. Anatomically duodenal diverticula are located in 10 to 67% in the second portion of duodenum, and its finding in most cases incidental. About 90% of patients appear asymptomatic, manifesting symptoms mostly once established complications such as: gastrointestinal bleeding and perforation., Clinical Case: 78-years-old woman who attended our Emergency department with dyspnea, moderate epigastralgia, abdominal bloating, constipation and difficulty to pass gas; Laparotomy was performed to identify duodenal diverticulum in the third portion of the duodenum with a perforation of 5 mm in its cupula. It proceeds with diverticulectomy., Conclusions: The diagnosis of duodenal diverticulum as a cause of acute abdomen must be considered in our differential diagnosis in acute abdomen supported by imaging and endoscopy. The surgical management of duodenal diverticulum, in particular the resection of the diverticulum, remains as the recommendation for treatment with less morbidity and a good recovery.

The duodenum is the second most common location of intestinal diverticula after the colon. Duodenal diverticulum (DD) is usually located in the second portion of the duodenum (D2), close to the papilla. Most duodenal diverticula are extraluminal and acquired rather than congenital; more rare is the congenital, intraluminal diverticulum. DD is usually asymptomatic and discovered incidentally, but can become symptomatic in 1% to 5% of cases when complicated by gastroduodenal, biliary and/or pancreatic obstruction, by perforation or by hemorrhage. Endoscopic treatment is the most common first-line treatment for biliopancreatic complications caused by juxtapapillary diverticula and also for bleeding. Conservative treatment of perforated DD based on fasting and broad-spectrum antibiotics may be offered in some selected cases when diagnosis is made early in stable patients, or in elderly patients with comorbidities who are poor operative candidates. Surgical treatment is currently reserved for failure of endoscopic or conservative treatment. The main postoperative complication of diverticulectomy is duodenal leak or fistula, which carries up to a 30% mortality rate., (Copyright © 2013. Published by Elsevier Masson SAS.)
