Prognostic factors and predictive models in hot gallbladder surgery: A prospective observational study in a high-volume center.

Backgrounds/Aims: The standard treatment for acute cholecystitis, biliary pancreatitis and intractable biliary colics ("hot gallbladder") is emergency laparoscopic cholecystectomy (LC). This paper aims to identify the prognostic factors and create statistical models to predict the outcomes of emergency LC for "hot gallbladder." Methods: A prospective observational cohort study was conducted on 466 patients having an emergency LC in 17 months. Primary endpoint was "suboptimal treatment," defined as the use of escape strategies due to the impossibility to complete the LC. Secondary endpoints were postoperative morbidity and length of postoperative stay. Results: About 10% of patients had a "suboptimal treatment" predicted by age and low albumin. Postop morbidity was 17.2%, predicted by age, admission day, and male sex. Postoperative length of stay was correlated to age, low albumin, and delayed surgery. Conclusions: Several predictive prognostic factors were found to be related to poor emergency LC outcomes. These can be useful in the decision-making process and to inform patients of risks and benefits of an emergency vs. delayed LC for hot gallbladder.

Prognostic factors in the decision-making process for sigmoid volvulus: results of a single-centre retrospective cohort study.

BACKGROUND: Sigmoid volvulus is a common cause of emergency surgical admission. Those patients are often treated conservatively with a high rate of recurrence. We wondered if a more aggressive management might be indicated. METHODS: We have reviewed data of patients diagnosed with acute sigmoid volvulus over a 2-year period. The primary endpoint was patient survival. RESULTS: We analysed 332 admissions of 78 patients. 39.7% underwent resection. Survival was 54.9 ± 8.8 months from the first hospitalization, irrespective of the treatment. Long-term survival was positively influenced by being female, having a low "social score", a younger age and surgery. Multivariate analysis showed that only being female and surgery were independently associated with better survival. CONCLUSION: Early surgery may be the best approach in patients with recurrent sigmoid volvulus, as it ensures longer survival with a better quality of life, regardless of the patient's social and functional condition.

COVID-19 infection risk by open and laparoscopic surgical smoke: A systematic review of the literature.

BACKGROUND: The current COVID-19 pandemic has greatly changed the way surgery is delivered. In particular, current guidelines and policies have highlighted the need to use high level Personal Protective Equipment to reduce the risk of viral infection during open and laparoscopic surgical procedures. In particular, it was felt that the laparoscopic approach was at higher risk of viral transmission due to the chimney effect of the smoke escape from the trocars during and after the procedure. However, with this being a new and largely unknown viral agent, guidelines have been based on speculation and extrapolation from previous studies conducted in completely different situations, and led to anxiety amongst surgeons and theatre staff. We decided to conduct a systematic review of the Literature to try to clarify whether inhalation of surgical smoke can increase the risk of COVID-19 infection. METHODS: A thorough search of the relevant Literature was performed following the PRISMA guidelines and the most relevant papers on this topic were selected for qualitative analysis. Duplicates, review, personal opinions and guidelines have been excluded. Quantitative analysis has not been performed due to the lack of homogeneous high-quality studies. RESULTS: Literature search identified 740 papers but only 34 of them were suitable for qualitative analysis. The quality of those studies is generally quite low. We were not able to find any evidence directly linking surgical smoke with viral transmission, other than in patients with active HPV infection. DISCUSSION: Inhalation of surgical smoke can be generally hazardous, and therefore the use of PPE during surgical operations must be recommended in any case. However, the present systematic review of the existent Literature did not identify any significant evidence of the risk of viral transmission with the surgical smoke, therefore the current guidelines restricting the use of laparoscopy and/or diathermy during the current Covid-19 pandemic may be considered excessive and non-evidence based.

Sumatriptan dose increase-induced acute angle closure glaucoma in chronic migraine sufferer.

In this case study, we explore a case of bilateral acute angle closure (AAC) attack detected in a 52-year-old female patient with no other ophthalmic background or predisposition to angle closure, following an increase of her regular sumatriptan dose used for migraine relief. Even though the initial presentation was misinterpreted as migraine attack, it nevertheless alerted the treating physicians to immediate cessation of the drug, allowing for the pertinent ocular symptomatology to be unveiled. Drug-induced bilateral AAC is a rare occurrence and can lead to significant ocular morbidity if not detected and treated early. Clinicians of emergency care should be aware of this uncommon association, as prompt ophthalmology input is vital. Interestingly, although it would be anticipated that people prone to angle closure attack after sumatriptan intake would exhibit symptoms after initiation of the drug, our patient suffered an attack while on long-term treatment and following dose increase.
