Foreign body ingestion in the upper digestive tract is a relatively common emergency. Less than 1% have to be treated surgically. We report the case of a 68-year-old man who ingested a dental prosthesis, probably during a seizure, and thus unknowingly, and presented two days later to the emergency department complaining of a mild dysphagia. A chest radiograph showed the presence of a removable dental prosthesis in the upper esophageal tract. The patient was brought to the operating room where a multidisciplinary equipe was assembled. Two attempts of retrieval with a flexible and a rigid endoscope failed because the removable dental prosthesis was stuck in the right pyriform sinus. Therefore, the surgeon performed an uncommon right cervicotomy and retrieved the foreign body through a right-side esophagotomy. The surgical approach depends on the nature and location of the foreign body. Urgent treatment is required whenever the patient develops dyspnea or dysphagia because of the high risk of inhalation and asphyxia. Removal of any esophageal foreign body has to be performed within 12–24 h. Repeated attempts to retrieve large dental prosthesis using an endoscope may result in esophageal perforation therefore when such risk of complication is too high, a surgical approach becomes inevitable. In our opinion, surgery remains the extrema ratio after a failed endoscopic retrieval attempt but can be lifesaving despite high risk of complications.

Meckel’s diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract with a 1–3% prevalence in the general population. The surgical management of symptomatic MD is well described in the literature, but there is still no consensus on the indication for prophylactic resection of incidental asymptomatic MD. To address this issue, we extensively reviewed the current literature and report our experience with laparoscopic management of an unusual case of MD causing ileal volvulus and acute peritonitis two weeks after a laparoscopic appendectomy for acute gangrenous appendicitis performed in another hospital. A 50-year-old man presented to the emergency department with acute and severe abdominal pain, vomiting, and constipation. He had undergone a laparoscopic appendectomy for acute appendicitis two weeks before in another hospital. The patient was apyretic, distressed, and seeking an antalgic position. The abdomen was mildly distended and tender, and the Blumberg sign was mildly positive in the central quadrants. The clinical picture deteriorated with fever, peritonismus, and leukocytosis. A CT scan showed an ileo–ileal adhesion near the ileocolic junction and dilatation of the upstream loops with the air–fluid levels. Through an urgent laparoscopy, a necrotic mass, the MD, was wedge-resected, and the surrounding ileal volvulus derotated. The postoperative course was uneventful. There is no definitive consensus on the appropriate management of incidental asymptomatic MD, although several studies have attempted to identify guiding criteria. Features of the MD, the patient’s risk factors, clinical presentation, and surgical approach need to be considered to establish definitive guidelines for the management of incidental asymptomatic MD. In the absence of definitive guidelines, personal expertise and judgement are the main resources for the surgeon approaching an incidental asymptomatic MD.

Delayed graft function (DGF) remains a relevant early complication after kidney transplantation (KT), and reliable non-invasive imaging markers may improve postoperative graft assessment. We retrospectively evaluated 381 KT recipients who underwent colour Doppler (CD) ultrasound (US) on postoperative day (POD) 1 and before discharge between January 2013 and February 2022. Resistive index (RI) measurements were analyzed in relation to DGF, defined as the need for at least one dialysis session within the first postoperative week. A prospective pilot subgroup of 25 recipients transplanted between February 2021 and February 2022 also underwent contrast-enhanced US (CEUS) between POD 1 and 3, with analysis of wash-in slope (WIS), time to peak (TTP), peak intensity (PI), and area under the curve (AUC). In the retrospective cohort, 71 (18.6%) developed DGF. Higher RI values on POD 1 and before discharge were significantly associated with DGF. In the CEUS pilot subgroup, 7 patients (28.0%) developed DGF. Among CEUS-derived parameters, AUC was significantly associated with DGF, with lower values in patients who developed DGF and a valuable ROC AUC of 0.794. These findings support a role for early postoperative CD in graft function assessment and suggest that CEUS-derived AUC may provide valuable complementary information in the early evaluation of grafts for DGF. However, the CEUS results are exploratory and require validation in larger prospective studies.

One of the main causes of post-transplant-associated morbidity and mortality is cancer. The aim of the project was to study the neoplastic risk within the kidney transplant population and identify the determinants of this risk. A cohort of 462 renal transplant patients from 2010 to 2020 was considered. The expected incidence rates of post-transplant cancer development in the referenced population, the standardized incidence ratios (SIR) taking the Italian population as a comparison, and the absolute risk and the attributable fraction were extrapolated from these cohort of patients. Kidney transplant recipients had an overall cancer risk approximately three times that the one of the local population (SIR 2.8). A significantly increased number of cases were observed for Kaposi's sarcoma (KS) (SIR 195) and hematological cancers (SIR 6.8). In the first 3 years post-transplant, the risk to develop either KS or hematological cancers was four times higher than in the following years; in all cases of KS, the diagnosis was within 2 years from the transplant. Post-transplant immunosuppression represents the cause of 99% of cases of KS and 85% of cases of lymphomas, while only 39% is represented by solid tumors. Data related to the incidence, the percentages attributable to post-transplant immunosuppression and the time of onset of neoplasms, particularly for KS and hematological tumors, could help improving the management for the follow-up in these patients.
