Spontaneous splenic rupture (SSR) is a relatively rare but potentially lethal complication of infectious mononucleosis (IM). While SSR is extremely rare in patients with proven IM, it is the most lethal complication of the infection (9% mortality rate) and can present completely asymptomatically or with abdominal pain and hemodynamic instability. As adolescents and young adults are the most affected population group, with this case report, we intend to raise the vigilance of any doctor treating those patients in the emergency department. We present the case of a 16-year-old patient with an atraumatic splenic rupture and hemoperitoneum secondary to an Epstein–Barr virus (EBV) infection. The patient underwent an exploratory laparotomy, and a splenectomy was performed. This case demonstrates that, even if SSR in patients with IM is extremely rare, it should always be considered in a patient with a relevant clinical presentation.

Vaginal cuff dehiscence can be a rare complication of total hysterectomy, with an estimated prevalence of 0.032% to 1.25% and a high mortality rate of 6 to 10%. Dehiscence is also reported in cases following total laparoscopic hysterectomy, with a prevalence of 0.87%. This case report details the emergency management of a 59-year-old female who complained of abdominal and pelvic pain and the feeling of a foreign body in her vagina. The patient reported a history of laparoscopic total hysterectomy 6 months prior to presenting at the Emergency Department. A clinical examination revealed small bowel loops protruding through the vagina. The patient underwent exploratory laparotomy through a Pfannenstiel incision, and the terminal ileum was found prolapsing through the vaginal cuff. The bowel loops were identified as viable and the vagina was sutured. The patient had an unremarked post operative course. This case report showcases that in patients with transvaginal evisceration, immediate surgical management is crucial in order to avoid serious life threatening complications, and both surgeons and gynecologists should remain vigilant regarding this pathology.

A 58-year-old female presented with abdominal pain, vomiting and constipation. Laboratory tests indicated elevated white blood cell count and C-reactive protein levels. Imaging via CT scan revealed a large cystic mass in the right ovary, abscesses and generalized small bowel distension, which initially raised suspicion of the existence of ovarian cancer with peritoneal carcinomatosis. Despite conservative management, the patient’s condition did not improve, prompting a laparotomy. Intraoperative findings included generalized peritonitis, significant small bowel dilation due to inflammatory adhesions and a perforated dermoid ovarian cyst. The cyst was resected and a prophylactic ileostomy was installed. Histopathological examination confirmed the diagnosis of a benign dermoid ovarian cyst. This case illustrates the rare presentation of a perforated dermoid cyst mimicking peritoneal carcinomatosis and emphasizes the importance of considering such complications in the differential diagnosis of bowel obstruction and peritoneal disease. Early recognition and appropriate surgical intervention are crucial for optimal outcomes.

In this 10-year retrospective study we used the data from patients who were operated upon due to acute bowel obstruction, at the Surgical Department of General Hospital of Katerini in Greece, from 2012 to 2022. Patients were classified based on the date of operation, their sex, their age group (ranging from 26 to 92 years) and the etiology of the bowel obstruction. A sample of 197 patients was studied. Out of these, it was found that in 73 (37%) the cause of the obstruction was colorectal cancer. In 46 of those patients (63%) the tumor was resected, while in the remaining 27 (37%), some kind of diverting stoma was installed. In 17(43,5%) of the 39 total patients, who suffered from some kind of rectosigmoid cancer, Hartmann's operation was chosen. Our results showcase that, at district hospitals, the surgeon is sometimes obligated to a damage control approach regarding obstructive colon cancer and thus the majority of the patients will eventually end up with a stoma.
