Duodenal Diverticulitis Following Biliopancreatic Diversion: A Case Report.

Duodenal diverticulitis is a relatively uncommon finding in patients. Treatment of complications of duodenal diverticulitis may be challenging in patients with altered intestinal anatomy such as those with altered anatomy from weight loss procedures involving intestinal bypass. We present a case report describing the management of duodenal diverticulitis following a biliopancreatic diversion, our decision-making process, and our final treatment strategy.

Diverticulitis associated pancreatitis: a report of 2 cases and review of the literature.

Duodenal diverticula are the second most common type of digestive diverticula after those in the colon. They are present in approximately 27% of patients who undergo upper digestive endoscopy. Most of these diverticula, especially those located near the papilla, are asymptomatic. However, in rare cases, they can be associated with obstructive jaundice (Lemmel Syndrome), bacterial infection, pancreatitis, or bleeding. In this report, we present two cases of acute obstructive pancreatitis caused by duodenal diverticulitis. Both patients were managed conservatively, resulting in a positive outcome.

Perforated Duodenal Diverticulitis: A Case Report of a Rare Surgical Entity Treated by Roux-en-Y Deriving Intestinal Patch.

Perforated diverticulitis is a rare but serious complication associated with a significant mortality rate. Although many cases of conservative treatment have been reported, surgery remains the mainstay for perforated duodenal diverticulitis. We report a rare case of a 55-year-old female who presented with epigastric pain without fever. Computed tomography revealed a 3 cm perforated duodenal diverticulum of the D2 part of the duodenum with a localized abscess. After the failure of conservative treatment, we performed a deriving intestinal patch completed by cholecystectomy and biliary decompression via a transcystic drain, as well as feeding jejunostomy. The patient was discharged on day 32. Removal of the transcystic drainage at eight weeks postoperatively was complicated by the appearance of an iatrogenic bilioperitoneum, which was effectively treated with percutaneous drainage. Surgery remains challenging; our experience suggests that perforation covering with a deriving jejunal patch offers an alternative to direct beach suturing when the latter is deemed precarious. Part of the treatment success lies in local drainage and duodenal exclusion that can be achieved by various surgical approaches.

Lemmel's Syndrome Secondary to Common Bile Duct Compression by an Inflamed Duodenal Diverticulum.

A 50-year-old female presented with acute epigastric abdominal pain, diarrhea, nausea, and vomiting for two days. Laboratory data showed hyperbilirubinemia and leukocytosis. Abdominal imagining was concerning for a pancreatic head/uncinate process lesion concerning a pancreatic neoplasm. Subsequent esophagogastroduodenoscopy with endoscopic ultrasound and endoscopic retrograde cholangiopancreatography found the major papilla adjacent to an inflamed and infected duodenal diverticulum, which was extrinsically compressing the distal common bile duct, causing biliary obstruction and common bile duct dilation. These findings are consistent with a diagnosis of Lemmel's syndrome. A biliary sphincterotomy was performed to relieve the obstruction and one temporary plastic biliary stent was placed into the common bile duct. The duodenal diverticulitis was treated with antibiotics for 10 days and the patient made a good recovery.

Duodenal Diverticulitis: To Operate or Not To Operate?

Duodenal diverticulum (DD) is a common incidental finding, which rarely causes complications. Perforation is one of the most feared and the least common complications. Surgery is the mainstay for complicated duodenal diverticulum, but with the advancement of medical treatment and intensive care, nonoperative management has been reported. We present a rare case of perforated DD that failed medical management and subsequently underwent surgical intervention. A 77-year-old, healthy female presented with right-sided abdominal pain with low-grade fever and leukocytosis. Computed tomography (CT) of the abdomen showed retroperitoneal fluid collection around the second part of the duodenum, which was not amenable to percutaneous drainage. Contrast studies showed no evidence of perforation or leak of the stomach or duodenum. The diagnosis was made via an upper endoscopy that showed a large periampullary duodenal diverticulum with purulent drainage and normal-looking ampulla. After failed conservative management with broad-spectrum antibiotics and worsening symptoms, she underwent excision and primary repair of the diverticulum with a jejunal serosal patch and exploration of the common bile duct (CBD). She had an uncomplicated postoperative course and was discharged home on postoperative day four. Although rare, the duodenal diverticular perforation can be a life-threatening complication. Combined subjective, clinical, and radiological assessment of the patient is crucial in deciding whether to operate or not.

Lemmel Syndrome Secondary to Duodenal Diverticulitis: A Case Report.

Lemmel syndrome occurs when a duodenal diverticulum causes obstructive jaundice due to a mechanical obstruction of the common bile duct. Additional pathophysiologic processes may also contribute to the development of Lemmel syndrome. These include duodenal diverticula causing dysfunction of the sphincter of Oddi as well as compression of the common bile duct by duodenal diverticula. It is uncommon for duodenal diverticulum to become inflamed. We report the case of a 25-year-old female presenting with unintentional weight loss and fatigue. Since her initial labs were concerning for possible infection with hepatobiliary abnormalities, a contrast-enhanced CT was obtained. This study revealed a large periampullary diverticulum with mucosal enhancement and fat stranding consistent with diverticulitis.

Duodenal diverticulitis accompanied by abscess formation treated successfully using an endoscopic nasobiliary drainage catheter: a case report.

Diverticulitis and diverticular abscesses are rare and potentially serious complications of duodenal diverticulum. These conditions often lead to perforation of the diverticulum, necessitating surgical treatment. There have been few reported cases of duodenal diverticulitis with or without perforation treated by endoscopic drainage. Here, we present a case of duodenal diverticulitis accompanied by abscess formation that was treated successfully with an endoscopic nasobiliary drainage catheter. We suggest this treatment could be an acceptable option for selected patients with a localized abscess that is resistant to conservative treatment.

A Case of Duodenal Diverticulitis Mimicking Cholangitis / 대한소화기내시경학회지

The duodenum ranks second to the colon as the most common site of diverticulosis in the gastrointestinal tract with a prevalence of more than 20%. It is usually asymptomatic, and rarely requires treatments for complications, including diverticulitis, hemorrhage, and luminal obstructions. Unlike diverticulosis, duodenal diverticulitis is extremely rare. Given that the radiological appearance and clinical presentation of duodenal diverticulitis often mimic those of pancreaticobiliary neoplasms or inflammations, it is a challenge for clinicians to diagnose it correctly, which often leads to misdiagnosis and inappropriate management. Here we report a case of a 69 year-old female patient with duodenal diverticulitis, whose clinical symptoms and radiological images were similar to those of acute cholangitis. We also briefly review the literature.
