Abstract
Introduction
Duodenal diverticula are quite prevalent in general population, seen on up to 5% of radiology studies and up to 22% of autopsy examinations.
Presentation of the case
70 years old female was admitted to the hospital with epigastric pain, fevers and elevated white cell count. Abdominal CT scan demonstrated evidence of perforated duodenal diverticulitis which failed to improve with IV antibiotics. Emergent pancreatoduodenectomy was performed with full recovery and uncomplicated hospital stay.
Discussions
Conservative therapy with antibiotics and bowel rest is successful in majority cases of perforation. Failure of conservative therapy demands surgical management. Variety of surgical approaches ranging from simple diverticulectomy to segmental resection, duodenal exclusion/bypass to pancreatoduodenectomy are available.
Conclusion
Pancreatoduodenectomy is an option when complicated duodenal diverticulum is not resolved with conservative or interventional therapy. This report has been written in concordance with the SCARE criteria Agha et al. [1].
1. Introduction
Duodenal diverticula are quite prevalent in general population, seen on up to 5% of radiology studies and up to 22% of autopsy examinations. [2] Only 5% of all diverticula will ever become symptomatic and develop complications. We present a case of surgical management of freely perforated duodenal diverticulum with peritonitis [1].
2. Case presentation
70 years old female was admitted to the hospital with epigastric pain, fevers and elevated white cell count. Abdominal CT scan demonstrated evidence of duodenal diverticulitis and she was started on broad-spectrum IV antibiotics (Fig. 1). Overnight, her clinical condition had worsened with persistent tachycardia, increase in white count, fevers and signs of peritonitis on exam. Interval CT revealed significant amount of air and fluid in the abdomen concerning for free perforation. Patient was consented for exploration and possible pancreatoduodenectomy. During surgery, large perforation of the 4 cm juxtapapillary duodenal diverticulum originating from posterior-medial wall with peritonitis was found (Fig. 2). Due to very medial location in close proximity to insertion of the ampulla, segmental resection was not possible and decision was made to proceed with pancreatoduodenectomy. Pathology confirmed perforation originating from duodenal diverticulum with no additional abnormal findings. Patient tolerated procedure without complications and was discharged home after 10-day hospital stay. She is doing well at 2 months follow up and has returned to work.

3. Discussion
Duodenal diverticula are quite prevalent in general population, seen on up to 5% of radiology studies and up to 22% of autopsy examinations.2 Only 5% of all diverticula will ever become symptomatic. Clinical presentations include diverticulitis, perforation with localized abscess, fistulization, duodenal and bilio-pancreatic obstruction and bleeding [2]. Endoscopic therapy is the main therapeutic tool for diagnosis and management of certain complications such as bleeding and pancreatic or biliary obstruction [[2], [3], [4], [5]]. Conservative therapy with antibiotics and bowel rest is successful in majority cases of perforation [5]. Failure of conservative therapy could be associated with high mortality and demands surgical management. Variety of surgical approaches ranging from simple diverticulectomy to segmental resection, duodenal exclusion/bypass to pancreatoduodenectomy are available [[3], [4], [5], [6]].
4. Conclusion
Pancreatoduodenectomy is very rarely performed in situation of acute perforation but may be used when all other approaches are limited due to perforation location and inability to carry out local/segmental resection [5].
