Laparoscopic excision of a Brunner's gland hamartoma of the duodenum

Brunneroma with duodenojejunal intussusception: a rare cause of gastric outlet obstruction

Duodenal adenoma presenting with duodenojejunal intussusception is very rare. Only a few have ever been reported. Upon evaluation it may be difficult to rule out malignancy. The final diagnosis may be reached only at surgery and confirmed at histopathology.

Rare presentation of Brunner's gland adenoma: another differentiation in patients with recurrent "idiopathic" pancreatitis

BACKGROUND

Brunner's gland adenoma (BGA) is an unusual benign neoplasm arising from Brunner's glands in the duodenum. When symptomatic it presents either with duodenal obstruction or bleeding. However, pancreatitis secondary to ampullary obstruction from a BGA is very rare.

METHODS

A 23-year-old female presented with recurrent episodes of "idiopathic" pancreatitis. She was extensively investigated and was found to have a large polypoid BGA, intermittently obstructing the ampulla. This created a ball-valve effect causing secondary intermittent obstruction of the pancreatic duct resulting in pancreatitis. The condition was cured surgically, through transduodenal excision of the BGA. We reviewed the surgical literature pertaining to these unusual and similar causes of obstructive pancreatitis, not related to gallstones.

RESULTS

BGA of the duodenum is a rare cause of pancreatitis. Extensive investigations should be carried out in all cases of unexplained pancreatitis before classifying the condition as "idiopathic". Discovery of a lesion of this nature gives an opportunity to provide a permanent surgical cure.

CONCLUSIONS

BGA adds an unusual etiology for pancreatitis. All patients with pancreatitis should undergo extensive investigations before being termed "idiopathic". Surgical excision of the BGA provides a definitive curative treatment for the adenoma and pancreatitis.

Hybrid resection of duodenal tumors

INTRODUCTION

The aim of this study was to review our experience with the hand-assisted laparoscopic management of duodenal tumors with no or low malignant potential and to compare this approach with published case reports of purely laparoscopic local duodenal resection.

PATIENTS AND METHODS

Eight cases of hand-assisted laparoscopic local duodenal resection performed from 2000 to 2008 were retrospectively reviewed. Hand-assistance was utilized for complete duodenal mobilization, and local duodenal resection was accomplished extracorporeally through the hand-access incision. Patient and tumor characteristics, operative time, length of stay, and complications were compared with 18 cases of totally laparoscopic local excision of duodenal tumors published since 1997. Patients with ampullary tumors were excluded.

RESULTS

Compared with the purely laparoscopic approach, the hand-assisted technique was associated with shorter operative time (179 versus 131 minutes, P=.03) and was more commonly used for lesions located in the third portion of the duodenum (0% versus 37.5%, P=.02). Tumor size (2.9 cm versus 3.2 cm, P=.61) and length of hospital stay (5.9 versus 5.9 days, P=.96) were similar between the two groups. The rate of complications was also comparable (0% versus 12.5%, P=.31); 1 of 8 patients in the hand-assisted group developed an incisional hernia at the hand-access site.

CONCLUSION

Hand-assisted laparoscopic local duodenal resection is a feasible, safe, and effective alternative to the totally laparoscopic approach. In addition to being associated with comparable length of hospital stay, hand-assistance can shorten operative time by facilitating duodenal mobilization as well as extracorporeal duodenal resection and closure.

Dual Transoral Endoscopic Resection of a Symptomatic Giant Brunneroma

Brunneroma is a rare, benign, proliferative lesion arising from the Brunner's glands of the duodenum that exceptionally may evolve towards a malignant transformation, usually discovered incidentally at endoscopy. Occasionally, these lesions manifest as a rare cause of duodenal obstruction or upper gastrointestinal bleeding and require resection, usually for tumors larger than 4 cm. The special aspect of our case is the technically difficult but successful dual transoral endoscopic resection of a giant (6.5 × 4 × 2.4 cm) brunneroma with a very thick and long peduncle located extremely close to the pylorus, highlighting the possibilities of endosurgery. Distal stomach resection with Roux-en-Y reconstruction as an alternative would have caused higher morbidity and costs.

Large Brunner’s gland adenoma: Case report and literature review

Brunner’s gland adenoma (BGA）is a very rare benign tumour of the duodenum, which is usually asymptomatic and discovered incidentally at endoscopy. Occasionally, this lesion may be large, causing upper gastrointestinal haemorrhage or intestinal obstruction. The case had a large Brunner’s gland adenoma, presenting melena that was managed by endoscopic excision.

[Gastrointestinal bleeding after endoscopic treatment of polypoid hamartoma (adenoma of Brunner's glands)]

The incidence of polypoidal tumors in the duodenum is scarce and Brunner's gland tumors represent 11% of these proliferations. Brunner's gland polypoid hamartoma or adenoma is a highly infrequent benign polypoid proliferation of Brunner's glands that is usually asymptomatic, although gastrointestinal bleeding or intestinal obstruction may sometimes occur. We present the case of a woman with an incidental diagnosis of duodenal polypoid hamartoma. The lesion was resected with polypectomy loop and at 48 h, the patient presented gastrointestinal bleeding as a complication. We describe the endoscopic treatment of the lesion and this complication.
