RESUMEN
PURPOSE: To assess the clinical outcomes and safety profiles of patients who underwent immediate sequential bilateral phakic lens surgery. METHODS: This retrospective multicenter study included 254 consecutive patients (508 eyes) who underwent bilateral same-day Implantable Collamer Lens (ICL) (STAAR Surgical) surgery. The authors focused on 1-year postoperative clinical outcomes and adverse events. RESULTS: In the initial cohort, 176 patients (352 eyes) met inclusion criteria. Of these, 335 eyes underwent myopic ICL placement, and 17 eyes received a hyperopic ICL. Notably, 87% of eyes achieved ±0.50 diopters (D) and 95% achieved ±1.00 D of the intended refraction. One year postoperatively, 78% of eyes demonstrated optimal vaulting (250 to 750 µm), with a significant 19% reduction in vaulting observed over the 12 months (P < .001). Only minor adverse events, including early cataract formation (1 case), secondary toric ICL rotation (3 cases), and ICL exchange due to inappropriate vaulting (6 cases), were noted. CONCLUSIONS: The findings corroborate the safety and efficacy of immediate sequential bilateral phakic lens surgery and indicate its potential as a treatment option. The low incidence of minor adverse events further reinforces its favorable safety profile. [J Refract Surg. 2024;40(5):e313-e320.].

PURPOSE: The protective role of bariatric surgery (BS) against COVID-19 has been reported by several studies, showing, in the first pandemic waves, better outcome of the infection in patients that had undergone BS. With the virus progressive endemicity, BS benefits on COVID-19 clinical course could appear less evident, while COVID-19 effects on BS outcomes must be investigated. In this national multicentric cross-sectional study, we compared COVID-19 incidence and clinical course between a cohort of patients that had undergone BS (OP) and a cohort of candidates to BS (WS); moreover, we analyzed BS outcomes based on SARS-CoV-2 positivity/negativity. METHODS: From June to December 2021, 522 patients from five Italian referral centers were administered an 87-item telephonic questionnaire completing the analysis of electronic medical records. Demographics, COVID-19 "tested" incidence, suggestive symptoms and clinical outcome parameters of OP and WS were compared. BS outcomes parameters were compared between OP that developed the disease or not. RESULTS: COVID-19 incidence was the same in OP and WS, while symptoms and clinical course seemed milder in OP, with no data individually reaching statistical significance. OP who developed SARS-CoV-2 infection had higher excess weight loss than negative OP (66.8% ± 22.1 vs. 57.7% ± 22.8, p = 0.029). Positive OP had had gastric-bypass (RYGB/OAGB) more frequently than negative ones (38.4% vs. 18.2%, p = 0.025). CONCLUSION: With the disease becoming endemic, BS protective role against COVID-19 seems clinically less relevant. BS outcomes can be affected by COVID-19, thus imposing careful follow-up for positive patients, especially if undergoing gastric-bypass.

hMTH1 protects against mutation during oxidative stress. It degrades 8-oxodGTP to exclude potentially mutagenic oxidized guanine from DNA. hMTH1 expression is linked to ageing. Its downregulation in cultured cells accelerates RAS-induced senescence, and its overexpression in hMTH1-Tg mice extends lifespan. In this study, we analysed the effects of a brief (5 weeks) high-fat diet challenge (HFD) in young (2 months old) and adult (7 months old) wild-type (WT) and hMTH1-Tg mice. We report that at 2 months, hMTH1 overexpression ameliorated HFD-induced weight gain, changes in liver metabolism related to mitochondrial dysfunction and oxidative stress. It prevented DNA damage as quantified by a comet assay. At 7 months old, these HFD-induced effects were less severe and hMTH1-Tg and WT mice responded similarly. hMTH1 overexpression conferred lifelong protection against micronucleus induction, however. Since the canonical activity of hMTH1 is mutation prevention, we conclude that hMTH1 protects young mice against HFD by reducing genome instability during the early period of rapid growth and maximal gene expression. hMTH1 protection is redundant in the largely non-growing, differentiated tissues of adult mice. In hMTH1-Tg mice, expression of a less heavily mutated genome throughout life provides a plausible explanation for their extended longevity.

INTRODUCTION: A considerable step forward in low rectal cancer resection has been done in the last decades. Maintaining total mesorectal excision as the gold standard treatment, new techniques such as Trans-Anal Mini-Invasive Surgery (TAMIS) and Trans-Anal Total Mesorectal Excision (TATME), which have been added to improve skills in laparoscopic and robotic surgery, currently represent the advancement of this procedure. Despite improvements in surgical techniques, complications after low anterior resection for rectal cancer still remain a challenge. Drainage and colostomy are the main treatments used to overcome the problem caused by anastomosis failure, and most patients will never been restored. Different techniques of redo surgery could be proposed to deal complex cases, although remaining high risk procedures. CASE PRESENTATION: We present two clinical cases with a late complication of the colorectal anastomosis: one with a late leakage of low colorectal anastomoses, treated with Hartman procedure, that developed a pelvic chronic sinus; the another one with complete anastomotic disruption after massive suture bleeding; both treated with delayed pull-through anastomosis, according to Turnbull-Cutait technique. We also made a review of relative literature, in order to back our therapeutic iters. DISCUSSION: Both the procedures were carried out satisfactorily, with restoration of intestinal continuity and good anastomotic result. It allows the resolutions of the chronic sepsis caused by the pelvic sinus and maintenance of intestinal continuity with a good Wexner incontinence score. Literary review demonstrated that this procedure still remains undervalued and not widely exploited. CONCLUSION: Delayed pull-through coloanal anastomosis could be considered as a valid option, in order to preserve intestinal continuity in septic or complicated low colorectal anastomosis.
RESUMEN
When colorectal cancer presents with liver metastasis, hepatic resection remains the most important factor in prolonging survival, and new paradigms have been proposed to augment resectability. An adequate liver remnant and vascularisation are the only limits in complex liver resection, and parenchyma-sparing surgery is a strategy for minimising the complications, preserving liver function, and allowing patients to undergo further liver resection. The laparoscopic approach represents a new challenge, especially when lesions are located in the superior or posterior part of the liver. We discuss the case of an 81-year-old patient with a single synchronous liver metastasis involving the left hepatic vein and leaning into the middle hepatic vein at the common trunk, where we performed a simultaneous laparoscopic colonic resection with a left sectionectomy extended to segment 4a. The strategic approach to the Arantius ligament by joining the left and middle hepatic vein allowed us to avoid a major liver hepatectomy, preserve the liver parenchyma, reduce complications, enhance patient recovery, and perform the entire procedure by laparoscopy. Our example suggests that the Arantius approach to the left hepatic vein and the common trunk could be a feasible approach to consider in laparoscopic surgery for lesions located in their proximity.
RESUMEN
The cause of pleural empyema is bacterial pneumonia and three stages has been described in the evolution of this disease: exudative, fibrino-purulent and organizational phases. The first therapeutic intervention is the antibiotic therapy; where pharmacological therapy alone is not sufficient to eradicate the infection, it is also necessary a surgical treatment. Since the province of Piacenza having been in the epicenter area during the first Sars-Cov 2 pandemic wave in March 2020 and the number of patients with Covid-related pneumonia required invasive and non-invasive respiratory support, had a considerable organizational impact on pulmonology and respiratory unit, hindering an optimal treatment of the bacterial pneumonia both in community as well as in the hospital. Among the many "collateral" damages of the epidemiological wave of the infection with Sars Cov-2, we have been able to observe in our Hospital, also an increase of pulmonary empyemas diagnosed at an advanced stage for what we believe to be organizational and social causes directly related to the pandemic: in order to cope with the emergency the Unit of Pneumology has been since March nearly uninterruptedly dedicated to the exclusive treatment of covid patients so the pneumologist has been removed due to the need from outpatient and residential management of general pneumology.

BACKGROUND AND AIMS: Diaphragmatic ruptures are associated with blunt abdominal or thoracic trauma and often occur in car and motorbike accident with a high energy impact. CASE PRESENTATION: We report two cases of patients victims of car and motorbike accidents that were referred to the Emergency Department of our Hospital in August and September 2017 for a politrauma. The patients were both diagnosed with a left diaphragmatic rupture with herniation of the stomach in the chest, and decomposed fractures of the ribs. One of the two patients reported a large abdominal wound with loss of substance in the site of the impact. Both patients underwent to open emergency surgery with primary repair of the phrenic rupture. The post-operative course was characterized by the occurrence of complications such as respiratory distress and emothorax for one of the patients. CONCLUSION: Traumatic rupture of the diaphragm can be associated to blunt or penetrating abdominal trauma in car and motorbike accident with a prevalence of the left-sided lesions. In patients with politrauma an associate rupture of the diaphragm should be always suspected especially in motor accident where high energy impact can generate a traumatic laceration of the respiratory muscle. The treatment of associate thoracic wall fractures to prevent weaning and respiratory distress in intubated patient should be discussed.

Swyer-James-MacLeod Syndrome (SJMS) is an uncommon, emphysematous disease characterized by obliteration of the small bronchioles, hypoplasia/or absence of pulmonary artery and peripheral vascular bed. It is most commonly diagnosed in childhood. Patients are often asymptomatic or they could suffer from symptoms of recurrent pulmonary infections. Spontaneous pneumothorax is a rare presentation of this syndrome. We report a case of a 42-year old female patient presented at our Emergency Department with complaints of dyspnea and pleuritic chest pain with a diagnosis of spontaneous pneumothorax in emphysematous disease. The diagnosis of SJMS is usually based on imaging and clinical findings rather than on the results of pathologic examination; indeed, asymptomatic adult patients with SJMS are often diagnosed after a chest radiograph obtained for another reason. High-resolution computed tomography (HRCT) seems to be the most appropriate technique for the diagnosis. SJMS can be associated with spontaneous pneumothorax which represent an emergency condition due to the underlying pathological disease. The surgical treatment of the affected lung should be considered when conservative approach is ineffective.
RESUMEN
BACKGROUND: Acute appendicitis (AA) is one of the most common causes of abdominal pain requiring surgical intervention. Approximately 20% of AA cases are characterized by complications such as gangrene, abscesses, perforation, or diffuse peritonitis, which increase patients' morbidity and mortality. Diagnosis of AA can be difficult, and evaluation of clinical signs, laboratory index and imaging should be part of the management of patients with suspicion of AA. METHODS: This consensus statement was written in relation to the most recent evidence for diagnosis and treatment of AA, performing a literature review on the most largely adopted scientific sources. The members of the SPIGC (Italian Polispecialistic Society of Young Surgeons) worked jointly to draft it. The recommendations were defined and graded based on the current levels of evidence and in accordance with the criteria adopted by the American College of Chest Physicians (CHEST) for the strength of the recommendations. RESULTS: Fever and migratory pain tend to be present in patients with suspicion of AA. Laboratory and radiological examinations are commonly employed in the clinical practice, but today also scoring systems based on clinical signs and laboratory data have slowly been adopted for diagnostic purpose. The clinical presentation of AA in children, pregnant and elderly patients can be unusual, leading to more difficult and delayed diagnosis. Surgery is the best option in case of complicated AA, whereas it is not mandatory in case of uncomplicated AA. Laparoscopic surgical treatment is feasible and recommended. Postoperative antibiotic treatment is recommended only in patients with complicated AA.

INTRODUCTION: Solitary fibrous tumors (SFTs) are rare spindle cells neoplasms most likely arising from mesenchymal cells. Usually they involve the pleura. Even if extra-thoracic SFTs are rare, lately they are diagnosed with increased frequency. CASE PRESENTATION: We describe the case of giant pelvic and retroperitoneal neoplasm, a rare solitary fibrous tumor, in a 51-year-old man that was admitted for abdominal pain. DISCUSSION: On CT a SFT appears usually as a smooth, lobulated mass with occasional calcifications, but the imaging differential diagnosis with other mesenchymal tumors is very difficult, if not impossible. CONCLUSION: The histological and immune-histochemical features of SFTs are helpful for the differential diagnosis. The malignant potential of this cancer is low, but it is very important to perform an optimized surgery and a close follow up in the patient. We believe that this case is particularly interesting and complex because of the difficulty of predicting the future biological behavior.
RESUMEN
The Sars-Cov2 Pandemic in Italy gave rise in Piacenza, northern Emilia, to one of the most extensive contagions ever recorded in Italy, the area being hit from the beginning of February, with all its dramatic force and enormous impact in terms of human lives, upsetting social lives. Piacenza is only few kilometers away from what was unexpectedly identified as the first known outbreak in the Western world, registered in Codogno, a small town in the province of Lodi, where the first verified Italian case of the infection Covid- 19 was isolated.Due to the advancement of the contagion and the exponential increase of Covid cases which required hospitalization all the surgical wards of our Hospital, except for the Emergency Surgery of the Hospital's central hub "Guglielmo da Saliceto" of Piacenza, were converted into Covid wards with various degrees of management care on behalf of the personnel, as also the operating theatres became new ICU units. Consequently, the professional life habits of the surgeons in general have radically changed: the surgeons have been working for about 70% of their working hours in internist support activities for the management of Covid-correlated pneumonia patients.Since then however, many questions have arisen during our daily reflections regarding the need for future planning of our surgery procedures: how much longer can we delay the planning of our selected surgery? Which epidemiological parameters, and other, should we identify in order to start up selected general surgery?For how long can selected surgery be deferred without compromising outcomes and mid to long term mortality in oncological patients in our province, considering also the diagnostic-therapeutic delays in these exceptional months of the Covid era?

INTRODUCTION: Malrotation of gut is a congenital anomaly of foetal intestinal rotation and it is mostly discovered in early childhood as acute intestinal obstruction. This condition is very rare and often silent in adults. PRESENTATION OF CASE: We present a case of 44-year-old woman admitted with acute abdominal pain. The abdominal CT scan showed ileal conglomerate loops with thickened walls filled of liquid in the right iliac side. Laparotomic Ladd's procedure was performed successfully with division of Ladd's band, adhesiolysis, reconstruction of Treitz's ligament, small bowel resection and Merckel's diverticulum removal. The patient made an unremarkable recovery. DISCUSSION: We discuss the rarity of intestinal malrotation in adulthood and made a literature review comparison of the therapeutic options available. CONCLUSION: Intestinal malrotation is a rare entity and adult presentation is even rarer. Some cases are asymptomatic, but when symptomatic a volvulus should be promptly suspected to avoid complications such as bowel ischemia.
RESUMEN
INTRODUCTION: Pneumatosis cystoides intestinalis (PCI) is a rare clinical pathology characterized by sub-mucosal and/or sub-serous cysts of free gas, forming cystic lesions usually ranging from 0.5 to 2.0â¯cm in size within the gastrointestinal tract. About 3% of patients with PCI develop complications such as pneumoperitoneum, intestinal volvulus, obstruction, or hemorrhage, these cases need immediate surgical intervention. Cyst rupture can produce peritoneal irritation and pneumoperitoneum. PRESENTATION OF CASE: A 65-years-old woman was admitted to the Emergency Department for epileptiform convulsions. Her medical hystory included epilepsy, diabetes, lichenoid dermatitis, hypothyroidism, severe cognitive impairment. Abdominal CT scan revealed a dilated large intestine with parietal pneumatosis from the appendix to the transverse colon associated to extensive pneumoperitoneum. The patient underwent emergency laparotomy which revealed the presence of gas within the wall of right and transverse colon and distension of great omentum. No resection was needed as normal blood supply to the bowel present. DISCUSSION: Pneumatosis coli can be both asymptomatic or life-threatening condition associated to bowel infarction; this situation can mimic a bowel perforation causing pneumoperitoneum - that sometimes is a non-surgical pneumoperitoneum - and it could be a misleading indication to surgical exploration especially in the case of uncertain origin of a septic shock. CONCLUSIONS: We report a case of pneuomoperitoneum due to PCI. Surgical intervention was required for patient's conditions and unclear origin of the sepsis.
RESUMEN
Several studies have demonstrated that training with a laparoscopic simulator improves laparoscopic technical skills. We describe how to build a homemade, low-cost laparoscopic training simulator (LABOT) and its validation as a training instrument. First, sixty surgeons filled out a survey characterized by 12 closed-answer questions about realism, ergonomics, and usefulness for surgical training (global scores ranged from 1-very insufficient to 5-very good). The results of the questionnaires showed a mean (±SD) rating score of 4.18 ± 0.65 for all users. Then, 15 students (group S) and 15 residents (group R) completed 3 different tasks (T1, T2, T3), which were repeated twice to evaluate the execution time and the number of users' procedural errors. For T1, the R group had a lower mean execution time and a lower rate of procedural errors than the S group; for T2, the R and S groups had a similar mean execution time, but the R group had a lower rate of errors; and for T3, the R and S groups had a similar mean execution time and rate of errors. On a second attempt, all the participants tended to improve their results in doing these surgical tasks; nevertheless, after subgroup analysis of the T1 results, the S group had a better improvement of both parameters. Our laparoscopic simulator is simple to build, low-cost, easy to use, and seems to be a suitable resource for improving laparoscopic skills. In the future, further studies should evaluate the potential of this laparoscopic box on long-term surgical training with more complex tasks and simulation attempts.

Background: Timing and adequacy of peritoneal source control are the most important pillars in the management of patients with acute peritonitis. Therefore, early prognostic evaluation of acute peritonitis is paramount to assess the severity and establish a prompt and appropriate treatment. The objectives of this study were to identify clinical and laboratory predictors for in-hospital mortality in patients with acute peritonitis and to develop a warning score system, based on easily recognizable and assessable variables, globally accepted. Methods: This worldwide multicentre observational study included 153 surgical departments across 56 countries over a 4-month study period between February 1, 2018, and May 31, 2018. Results: A total of 3137 patients were included, with 1815 (57.9%) men and 1322 (42.1%) women, with a median age of 47 years (interquartile range [IQR] 28-66). The overall in-hospital mortality rate was 8.9%, with a median length of stay of 6 days (IQR 4-10). Using multivariable logistic regression, independent variables associated with in-hospital mortality were identified: age > 80 years, malignancy, severe cardiovascular disease, severe chronic kidney disease, respiratory rate ≥ 22 breaths/min, systolic blood pressure < 100 mmHg, AVPU responsiveness scale (voice and unresponsive), blood oxygen saturation level (SpO2) < 90% in air, platelet count < 50,000 cells/mm3, and lactate > 4 mmol/l. These variables were used to create the PIPAS Severity Score, a bedside early warning score for patients with acute peritonitis. The overall mortality was 2.9% for patients who had scores of 0-1, 22.7% for those who had scores of 2-3, 46.8% for those who had scores of 4-5, and 86.7% for those who have scores of 7-8. Conclusions: The simple PIPAS Severity Score can be used on a global level and can help clinicians to identify patients at high risk for treatment failure and mortality.

INTRODUCTION: Left sided gallbladder is a rare congenital abnormality more often discovered as incidental finding during laparoscopic cholecystectomy requiring surgical challenge to prevent complication. We present a case of a true left sided gallbladder treated with laparoscopic cholecystectomy. CASE: A 90 y/o woman with acute abdominal pain was hospitalised and underwent a laparoscopic cholecystectomy. A preoperative CT scan didn't show the variation. Intraoperative finding revealed a true left sided gallbladder that was carefully dissected at the Calot's triangle with identification of the cystic duct and artery. After a complete separation of the gallbladder from the liver, the cystic duct and the artery were safely clipped and transected. CT scan reconstruction reveal agenesis of the right superior sector with simultaneous absence of the right biliary duct. DISCUSSION: True left sided gallbladder is defined as one attached in the left of the ligamentum teres and falciform ligament. This abnormality predispose to a numerous anatomical variation. Unfortunately its finding is more often incidentally during intervention and recognition of such variation could be difficult that can be of high risk for surgical injury. CONCLUSION: Left sided gallbladder presents a significant challenge to the surgeon and makes it even more difficult to avoid postoperative complications. Therefore, a careful dissection of Calot's triangle and the complete mobilisation of the gallbladder should be done before clipping the cystic duct and artery. However, if a preoperative finding suggests a left sided gallbladder, then an in-depth preoperative anatomical study is advocated.
RESUMEN
PFAS (perfluoroalkyl substances) are considered non-genotoxic. However, PFAS exposure has been associated with the induction of oxidative stress in vitro and in vivo, and the possible induction of indirect genotoxic effects under sustained PFAS exposure has not been investigated. In order to shed light on this aspect, in this study a comprehensive assessment of genotoxicity was carried out in mice administered with perfluorooctanoic acid (PFOA, 0.1, 1 and 5â¯mg/kg body weight) and its C4 analogue perfluorobutyric acid (PFBA, 5â¯mg/kg body weight) for five weeks through drinking water. Markers of cell toxicity, oxidative stress and DNA strand breaks were measured in liver, the main target of toxicity of PFOA in rodents; systemic genotoxicity was also assessed by the analysis of micronuclei in reticulocytes and spleen lymphocytes, and germ cell effects by the Comet assay on testis cells. PFOA administration at the highest dose (5â¯mg/kg body weight) induced marked liver hypertrophy with signs of cell injury (elevated ALT and AST), with no concurrent evidence of lipid peroxidation and oxidative stress (decreased antioxidant capacity). Only mild liver hypertrophy, with no other signs of toxicity, was determined by PFBA administration. No evidence of treatment related genotoxicity was observed in any experimental group. Overall, data indicate that under the experimental conditions of this study, severe liver toxicity induced by PFOA administration is not associated with oxidative stress. Accordingly, no genotoxic effect is observed in liver and in the other tissues examined. Milder evidence of liver toxicity, with no genotoxicity, and a lower tendency to bioaccumulation were observed in PFBA treated mice.
