BRIEF EXPLANATIONP OSTOPERATIVE COMPLICATIONS OF pancreatic surgery can be life-threatening and lead to major morbidity and mortality. 1 The most common complication after pancreatic surgery is peripancreatic fluid collection (PFC), which has been reported in up to 50% of cases. 1-3 A 70-year-old Japanese man underwent radical distal laproscopic pancreatectomy for pancreatic cancer. This was performed using purple Tri-Staple cartridges (Medtronic, Minneapolis, MN, USA). PFC was observed postoperatively, and the patient was treated conservatively with postoperative surgical drainage. The pancreatic endocavitary drain was removed on postoperative day 28, and the patient was discharged on day 33. However, the patient reported sudden abdominal pain on day 37. Abdominal computed tomography revealed high-contrast objects in the remnant main pancreatic duct (R-MPD)
A 44-year-old woman with an unremarkable medical history presented to another hospital complaining of lower abdominal pain and nausea. The clinical presentation was consistent with an acute abdomen, raising suspicion of gastrointestinal tract perforation. However, imaging studies failed to provide evidence of perforation. Subsequently, the patient was diagnosed with peritonitis of unknown origin and promptly administered broad-spectrum antibiotics in a fasting state. Although the patient initially exhibited unstable symptoms, hemodynamics, and serology, she gradually improved over three days, with values approaching normal levels. On the sixth day of hospitalization, a follow-up abdominal computed tomography scan revealed pleural effusions, extensive ascites, and intra-abdominal stranding. The thickened wall of the small intestine and intra-abdominal stranding that were suggestive of peritonitis were further exacerbated. On the seventh day of hospitalization, aerobic and anaerobic blood cultures revealed the presence of Gram-positive cocci, later confirmed to be

infection-induced primary peritonitis. The source of infection was identified as a 10 mm hydrosalpinx in the left fallopian tube, suggesting the possibility of retrograde infection. The patient ultimately made a complete recovery without relapse and has been doing well since. This case report highlights a unique and rare occurrence of primary peritonitis caused by group A Streptococcus associated with infection from a hydrosalpinx in an otherwise healthy and young female patient. The diagnosis of primary spontaneous bacterial peritonitis in such an individual presents an uncommon clinical manifestation, emphasizing the importance of considering atypical sources of peritoneal infection in clinical practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
