RESUMO

This case report depicts the diagnosis and management of the largest documented appendicolith found in the medical literature so far, measuring 4.5 cm. A 44-year-old male patient presented with a distended abdomen, right lower quadrant (RLQ) pain, constipation, and the inability to consume solid food. Laboratory tests revealed leukocytosis and elevated C-reactive protein (CRP) levels. Abdominal X-rays showed a densely calcified structure in the right lower quadrant, and further imaging confirmed the diagnosis of appendicolithiasis. The surgical indication for appendectomy was determined, and an open surgical procedure was performed due to the severity of inflammation, minimal perforation, and extensive adhesions. The surgically removed appendix with the appendicolith was analyzed histologically, confirming appendicolithiasis, periappendicitis, perforation, and serositis. The patient was discharged in stable condition after postoperative management. Giant appendicoliths are rare and associated with an increased risk of complications. Diagnosis is typically clinical but can be enhanced by imaging modalities.

RESUMO

Background: Platelets were shown to be relevant for liver regeneration. In particular, platelet-stored serotonin (5-HT) proved to be a pro-regenerative factor in this process. The present study aimed to investigate the perioperative course of 5-HT and evaluate associations with patient and graft outcomes after othotopic liver transplantation (OLT). Methods: 5-HT was quantified in plasma and serum of 44 OLT recipients perioperatively, and in their respective donors. Olthoff's criteria for early allograft dysfunction (EAD) were used to evaluate postoperative outcomes. Results: Patients with higher donor intra-platelet 5-HT per platelet (IP 5-HT PP) values had significantly lower postoperative transaminases (ASAT POD1: p = 0.006, ASAT POD5: p = 0.006, ASAT POD10: p = 0.02, ALAT POD1: p = 0.034, ALAT POD5: p = 0.017, ALAT POD10: p = 0.04). No significant differences were seen between postoperative 5-HT values and the occurrence of EAD. A tendency was measured that donor IP 5-HT PP is lower in donor-recipient pairs that developed EAD (p = 0.07). Conclusions: Donor IP 5-HT PP might be linked to the postoperative development of EAD after OLT, as higher donor levels are correlated with a more favorable postoperative course of transaminases. Further studies with larger cohorts are needed to validate these findings.

RESUMO

BACKGROUND: Low anterior resection syndrome (LARS) is a common functional disorder after low anterior resection impacting the quality of life. Data on LARS derives nearly exclusively from rectal cancer studies. Therefore, the study was designed to assess LARS in advanced epithelial ovarian cancer (EOC) patients, who underwent rectal resection and to compare it with a female rectal cancer cohort. MATERIAL AND METHODS: A cross-sectional multi-centre analysis was performed on female patients suffering from either rectal or EOC who received a low anterior resection as part of their therapy regimen. None of the patients received pre- or postoperative radiotherapy. LARS was defined by using the validated LARS score and its severity was divided into "no", "minor" and "major LARS". RESULTS: In total, 125 female patients (44.8% (n = 56) EOC vs. 55.2% (n = 69) rectal cancer patients) met the final inclusion criteria and were retrospectively analyzed. Baseline characteristics were comparable between the groups. Median follow-up was 22 (IQR 12-56) months. In total, 30.4% (n = 38) of the patient group reported bowel dysfunction after surgery. Rates of LARS were not significantly different between EOC and rectal cancer patients (major LARS 16.1% (n = 9) vs. 15.9% (n = 11); minor LARS 17.9% (n = 10) vs. 11.6% (n = 8); p = 0.984). The time interval between surgery and final assessment had no impact on the postoperative bowel function (p = 0.820). CONCLUSION: LARS is a frequent and highly underreported postoperative disorder in EOC patients who require cytoreductive surgery with rectal resection. The functional outcome is comparable to female patients with rectal cancer who underwent low anterior resection without receiving radiotherapy.
