Early laparoscopic cholecystectomy in severely comorbid patients with acute cholecystitis: results of a monocentric study.

Aim: The aim is to evaluate laparoscopic cholecystectomy safety based on American Society of Anesthesiologists score for acute cholecystitis in patients with comorbidities. Patients & methods: This is retrospective study of patients who underwent laparoscopic cholecystectomy for acute cholecystitis between 2003 and 2021. According to their respective ASA-score, patients were divided into group 1: ASA1-2 and group 2: ASA3-4. Results: We collected 578 patients. Even though the gangrenous forms were more frequent and the operative time was longer in group 2, laparoscopic cholecystectomy seems safe and effective. We didn't observe any differences in terms of intraoperative incidents, open conversion rate, or postoperative complications compared with other patients. Conclusion: ASA3-4 patients with acute cholecystitis don't face elevated risks of complications or mortality during laparoscopic cholecystectomy.

This study, involving 578 patients with acute cholecystitis, assessed the safety of early laparoscopic cholecystectomy based on their health scores. Despite longer operative times and more gangrenous forms in higher-scored patients, laparoscopic cholecystectomy was found to be safe and effective. No significant differences in complications or mortality were observed compared with lower-scored patients. In conclusion, early laparoscopic cholecystectomy is considered a safe option for patients with higher health scores facing acute cholecystitis.

Study assessed laparoscopic cholecystectomy safety in high-risk patients with acute cholecystitis based on ASA scores. Despite longer operative times, it's a safe and effective option. #CholecystectomySafety.

Functional analysis of MMR gene VUS from potential Lynch syndrome patients.

Lynch syndrome is caused by inactivating variants in DNA mismatch repair genes, namely MLH1, MSH2, MSH6 and PMS2. We have investigated five MLH1 and one MSH2 variants that we have identified in Turkish and Tunisian colorectal cancer patients. These variants comprised two small deletions causing frameshifts resulting in premature stops which could be classified pathogenic (MLH1 p.(His727Profs*57) and MSH2 p.(Thr788Asnfs*11)), but also two missense variants (MLH1 p.(Asn338Ser) and p.(Gly181Ser)) and two small, in-frame deletion variants (p.(Val647-Leu650del) and p.(Lys678_Cys680del)). For such small coding genetic variants, it is unclear if they are inactivating or not. We here provide clinical description of the variant carriers and their families, and we performed biochemical laboratory testing on the variant proteins to test if their stability or their MMR activity are compromised. Subsequently, we compared the results to in-silico predictions on structure and conservation. We demonstrate that neither missense alteration affected function, while both deletion variants caused a dramatic instability of the MLH1 protein, resulting in MMR deficiency. These results were consistent with the structural analyses that were performed. The study shows that knowledge of protein function may provide molecular explanations of results obtained with functional biochemical testing and can thereby, in conjunction with clinical information, elevate the evidential value and facilitate clinical management in affected families.

Median arcuate ligament syndrome (Dunbar syndrome): A diagnosis not to be underestimated.

Medial arcuate ligament syndrome (MALS) is an anatomoclinical entity underestimated in most situations due to the lack of specific signs. However, the consequences can be disastrous if the diagnosis is not seriously considered and investigations are not fully undertaken to confirm this hypothesis. We report a case of Median Arcuate Ligament Syndrome in a young woman who presented to the Emergency Department with moderate postprandial pain. All investigations were carried out promptly, with no abnormalities, and the diagnosis was retained on the evidence of a well-performed and appropriately interpreted abdominal CT. This case illustrates a rare cause of epigastralgia simulating a surgical emergency. This condition should be considered when biological and often radiological investigations are inconclusive. The relative youth of the patient is often suggestive, but confirmation is based on a CT scan with injection of a well-technical contrast product, or angiography. Treatment is debatable between a conservative approach and surgery. Surgical approach is discussed depending on the degree of vascular stenosis and the impact on the digestive tract. However, the recurrence of symptoms may be a contributory factor in the therapeutic decision. The impact could be lethal depending on the degree of stenosis and consequently on the repercussions on the digestive tract. A multidisciplinary approach is required for its management.
