One-stage approach to cholecystocholedocholithiasis treatment: a feasible surgical strategy for emergency settings and frail patients.

BACKGROUND: Cholecystocholedocholithiasis (CCL) occurs in up to 18% of patients undergoing laparoscopic cholecystectomy (LC). The two-stage treatment using endoscopic retrograde cholangiopancreatography (ERCP) followed by LC is the treatment of choice for CCL. However, only 10 to 60% of patients have common bile duct (CBD) stones at the time of ERCP, thus exposing patients to unnecessary ERCPs, causing 3 to 15% of post-interventional pancreatitis. One-stage laparoscopic-endoscopic rendezvous (LERV) is an alternative for the treatment of CCL. Given the selective top-to-bottom CBD cannulation, LERV reduces the risk of pancreatitis and failed CBD cannulation. Additionally, LERV is performed exclusively in patients presenting CBD stones at intraoperative cholangiography, avoiding unnecessary ERCPs. Despite its advantages, considering the logistical burden of coordinating different specialties, LERV is performed in few centers. Here, we present the largest retrospective series of LERVs performed at our department, analyzing elective and emergency procedures. METHODS: All consecutive patients undergoing LERV for CCL between January 2014 and December 2021 were included. LERV success rate, operative time, biliary outflow restoration rate, postoperative complications (POC), length of hospital stay (LOS), and recurrences were analyzed. RESULTS: 181 patients were included (61 elective LERVs, 120 emergency LERVs). We reported a 100% LERV success rate, a 97.79% biliary outflow restoration rate, a 0% conversion rate, a mean intraoperative time of 120.17 ± 31.35 min, and LOS of 4.00 ± 2.82 days. POC included 7 Clavien-Dindo type 1, 11 type 2, and 3 type 3 cases. Seven patients presented with CBD stone recurrence: 2 within 30 days after discharge, 3 within 6 months after discharge, and 2 patients at 1 year. No statistically significant difference was found between elective and emergency patients. CONCLUSION: LERV is safe, representing a valid option even in emergency settings, thus enabling the management of CCL within a single procedure, consequently sparing additional anesthesia and decreasing post-ERCP complications.

Effectiveness and Safety of A Nutraceutical Formulation for the Treatment of Functional Dyspepsia in Primary Care.

BACKGROUND: Although FD may affect up to 10% of the general population, the therapy for FD is not standard. Recently, ginger-based food supplements have been proposed in order to restore FD symptoms. Our aim was to assess the efficacy of a new nutraceutical formulation containing extract of gingerol and thymus as a possible natural treatment in managing the symptoms of functional dyspepsia (FD). METHODS: We retrospectively analyzed the efficacy and safety profiles of a nutraceutical formulation containing Zingiber officinalis root extract and a standardized Thymus extract. It was administered as 1 ml/day twice a day for 90 days. Patients were assessed at baseline and after 1, 2 and 3 months of treatment, following a month of pharmacological washout by completing a questionnaire reporting the trend of the following symptoms: epigastric pain, epigastric heaviness, early satiety, belching, and regurgitation. Every symptom was assessed by a Visual Analogic Scale (VAS), ranging from 0= absence to 10= maximal severity. RESULTS: We enrolled 272 patients (99 males and 173 females; median IQR age 49.5, 36-64 yrs). Obesity (BMI>30) was present in 28 (12.5%) patients; smokers were 83 (30.5%); and comorbidities were present in 107 (39.3%) patients. Improvement of symptom scores during treatment and one month after its suspension was extremely significant (p<0.000). CONCLUSION: This large study found that nutraceutical formulation could be one of the tools for an empirical approach to treat patients with FD, especially when a non-conventional drug treatment is preferable for the patient and considered suitable by the physician.

Record Rate Enhancements for Tetrathiafulvalene Guests in the Formation of Bipyridinium- and Diazapyrenium-Based [2]Pseudorotaxanes.

The catalytic effects of guests 5-7 on the cyclization of 1 and 3 have been measured at 62 °C in MeCN. A record rate acceleration of more than 2000 times has been observed in the cyclization of the tricationic host 3 featuring large diazapyrenium π-surfaces by tetrathiafulvalene guests 6 and 7. The results emphasize the role played by extended π-surfaces in the host and the goodness of a tetrathiafulvalene core in the guest, enhanced by polyethereal side arms.

[Colorectal cancer surgery. Analysis of risk factors in relation to incidence of morbidity and mortality]. / Chirurgia oncologica colo-rettale. Analisi dei fattori di rischio nell'incidenza di morbi-mortalità.

The aim of the study was to investigate risk factors in relation to the incidence of morbidity and mortality in surgery for colorectal cancer. Between 1986-2005, 328 patients underwent colorectal cancer surgery, 308 of whom (93.9%) in elective and 20 (6.1%) in emergency surgery. Radical resection was performed in 276 (84.2%) and palliative surgery in 52 (15.8%) patients. Bivariate statistical analysis was used for morbidity and mortality factors and multivariate analysis was performed in order to find independent variables (age, gender, ASA grade, elective or emergency surgery, tumour excision, cancer stage according to Dukes) associated with dependent variable interactions. Differences were considered statistically significant for p values < 0.05. The incidences of mortality and morbidity were 0.91% and 20.1%, respectively. In our study we observed a leakage incidence of 2.74% (9/328). In emergency surgery we found morbidity and mortality rates of 20% and 10%, respectively. Age and advanced cancer stage influenced results but were not found to be statistically significant. 18.3% of patients (60/328) were ASA I, 32% (105/328) ASA II, 39.6% (130/328) ASA III and 10.1% (33/328) ASA IV. Among the independent variables observed in the multivariate analysis, ASA grade was found to be the only positive predictive factor correlated with morbidity. Logistic regression showed an exponential increase in operative risk: odds ratio (OR) 2.9 in ASA I vs ASA II, OR 4.2 in ASA I vs ASA Ill, OR 10.3 in ASA I vs ASA IV (95% confidence interval). As regards the mortality rate, none of the independent variables were found to be statistically significant risk factors (p < 0.05).

[Extrauterine endometriosis: what interest for the general surgeon? Presentation of 3 clinical cases and review of the literature]. / Endometriosi extrauterina: quale interesse per il chirurgo generale? Presentazione di 3 casi clinici e revisione della letteratura.

Extragonadal endometriosis is rarely diagnosed preoperatively for the variety of its localizations. Presentations to general surgeons may be atypical and pose diagnostic difficulty, mimicking other acute diseases. We report three cases treated with surgical operation. Case 1: a 28-year-old woman admitted for bowel obstruction due to coecal endometriosis, with appendix mucocele, peritoneal pseudomyxoma and ovarian endometrioma. The patient underwent right colectomy and right adnexectomy in the emergency setting. Case 2: a 31-year-old woman with endometriosis of the distal extraperitoneal portion of the round ligament presenting as an irreducible inguinal hernia. An operation was performed: the round ligament and a polycystic structure encompassing it were completely excised. Case 3: a 41-year-old woman, with umbilical endometriosis diagnosed by her gynaecologist, was admitted to our department for excision. Surgical treatment of extragonadal endometriosis is adequate. However, postoperative follow-up is mandatory and hormonal suppressive therapy may be indicated by the gynaecologist.

[Severity of anemia and operative morbidity and mortality. Report on 3 clinical cases in Jehovah's Witnesses and review of the literature]. / Morbi-mortalità operatoria relativa alla severità dell'anemia acuta. Presentazione di 3 casi clinici complicati in pazienti Testimoni di Geova e revisione della letteratura.

It has been reported that patients who refuse blood transfusions, such as Jehovah's witnesses, can undergo major surgery. In a review of the literature, however, we critically examined the severity of anaemia in relation to operative mortality and morbidity rates. We report three cases of Jehovah's witnesses who underwent major surgery and presented complication during the postoperative period. Case 1: a 50-year-old man with oesophageal achalasia who underwent Heller's myotomy and Nissen's fundoplication. The postoperative period was complicated by massive haemorrhage and the patient was reoperated on postoperative day 1. After four years, he underwent total oesophagectomy because of severe chronic oesophagitis. On postoperative day 13 the patient suffered anteroseptal myocardial ischaemia, which was treated with medical therapy. Case 2: a 40-year-old man, admitted for ulcerative rectocolitis, who underwent total colectomy. On postoperative day 1 he presented massive haemorrhage and shock. He was reoperated and the postoperative period was complicated by myocardial ischaemia, renal failure and an enterocutaneous fistula. Case 3: a 65-year-old woman with ulcerative rectocolitis who underwent total colectomy and a temporary ileostomy. She suffered venous thrombosis of the lower limbs and pulmonary oedema. The patient died 14 months after surgery as a result of massive haemolysis by cryoagglutinins and cardiac arrest.
