Endosonography-Guided Versus Percutaneous Gallbladder Drainage Versus Cholecystectomy in Fragile Patients with Acute Cholecystitis-A High-Volume Center Study.

Background and Objectives: Acute cholecystitis is a frequent cause of admission to the emergency department, especially in old and frail patients. Percutaneous drainage (PT-GBD) and endosonographic guided drainage (EUS-GBD) could be an alternative option for relieving symptoms or act as a definitive treatment instead of a laparoscopic or open cholecystectomy (LC, OC). The aim of the present study was to compare different treatment groups. Materials and Methods: This is a five-year monocentric retrospective study including patients ≥65 years old who underwent an urgent operative procedure. A descriptive analysis was conducted comparing all treatment groups. A propensity score was estimated based on the ACS score, incorporated into a predictive model, and tested by recursive partitioning analysis. Results: 163 patients were included: 106 underwent a cholecystectomy (81 laparoscopic (LC) and 25 Open (OC)), 33 a PT-GBD and 21 EUS-GBD. The sample was categorized into three prognostic groups according to the adverse event occurrence rate. All patients treated with EUS-GBD or LC resulted in the low risk group, and the adverse event rate (AE) was 10/96 (10.4%). The AE was 4/28 (14.2%) and 21/36 (58.3%) in the middle- and high-risk groups respectively (p < 0.001). These groups included all the patients who underwent an OC or a PT-GBD. The PT-GBD group had a lower clinical success rate (55.5%) and higher RR (16,6%) when compared with other groups. Conclusions: Surgery still represents the gold standard for AC treatment. Nevertheless, EUS-GBD is a good alternative to PT-GBD in terms of clinical success, RR and AEs in all kinds of patients.

Clinical Frailty Score is a good predictor of postoperative mortality in patients undergoing open abdomen surgery: a multicenter retrospective cohort study.

BACKGROUND: Open Abdomen (OA) is gaining popularity in damage control surgery (DCS) but there is not an absolute prognostic score to identify patients that may benefit from it. Our study investigates the correlation between the clinical frailty scale score (CFSS) and postoperative morbidity and mortality in patients undergoing OA. METHODS: Patients ≥65 yo undergoing OA in two referral centres between 2015 and 2020 were included and stratified according to CFSS in non-frail (NF), frail (F) and highly-frail (HF). The primary endpoint was 30-day mortality. Secondary endpoints were postoperative morbidity and 1- year survival. RESULTS: One hundred and thirty-six patients were included: 35 NF (25.7%), 56 F (41.2%), 45 HF (33.1%). Average age 76.8. The 73.5% of cases were non-traumatic diseases with no difference in preoperative characteristics. 95 (71.4%) had one complication, 26 NF (74.3%), 34 F (63.2%), 35 HF (77.8%) (P=0.301) and 59.4% had a complication with a CD≥3, 57.1% NF, 56.6% F and 64.4 HF. The 30-day mortality was 32.4%, higher in HF (46.7%) and F (30.4%) compared to NF (17.1%, P=0.018). The Overall 1-year survival was 41% (SE ±4) with statistically significant difference between HF vs. NF and HF vs. F (P=0.009 and P=0.029, respectively). In the univariate analysis, the only significant prognostic factor impacting mortality was CFSS, with HF having an HR of 1.948 (95% CI 1.097-3.460, P=0.023). CONCLUSIONS: When OA is a surgical option, frail patients should not be precluded, while HF should be carefully evaluated. The CFSS might be a good prognostic score for patients that may safely benefit from OA.

State of the art of trauma teams in Italy: A nationwide study.

Trauma teams play a vital role in providing prompt and specialized care to trauma patients. This study aims to provide a comprehensive description of the presence and organization of trauma teams in Italy. A nationwide cross-sectional epidemiological study was conducted between July and October 2022, involving interviews with 137 designated trauma centers. Centers were stratified based on level: higher specialized trauma centers (CTS), intermediate level trauma centers (CTZ + N) and district general hospital with trauma capacity (CTZ). A standardized structured interview questionnaire was used to gather information on hospital characteristics, trauma team prevalence, activation pathways, structure, components, leadership, education, and governance. Descriptive statistics were used for analysis. Results showed that 53 % of the centers had a formally defined trauma team, with higher percentages in CTS (73 %) compared to CTZ + N (49 %) and CTZ (39 %). The trauma team activation pathway varied among centers, with pre-alerts predominantly received from emergency medical services. The study also highlighted the lack of formally defined massive transfusion protocols in many centers. The composition of trauma teams typically included airway and procedure doctors, nurses, and healthcare assistants. Trauma team leadership was predetermined in 59 % of the centers, with anesthesiologists/intensive care physicians often assuming this role. The study revealed gaps in trauma team education and governance, with a lack of specific training for trauma team leaders and low utilization of simulation-based training. These findings emphasize the need for improvements in trauma management education, governance, and the formalization of trauma teams. This study provides valuable insights that can guide discussions and interventions aimed at enhancing trauma care at both local and national levels in Italy.

Spread and feasibility of non-operative management (NOM) of traumatic splenic injuries in adults: a national survey.

In hemodynamically stable adults sustaining a splenic trauma, non-operative management (NOM) represents the standard approach even in high-severity injuries. However, knowledge, structural, and logistic limitations still reduce its wider diffusion. This study aims to identify such issues to promote the safe and effective management of these injuries.A survey was developed using the SurveyMonkey® software and spread nationally in Italy. The survey was structured into: (1) Knowledge of classification systems; (2) Availability to refer patients; (3) Patients monitoring and follow-up; (4) Center-related.The survey was filled in by 327 surgeons, with a completeness rate of 63%. Three responders out of four are used to manage trauma patients. Despite most responders knowing the existing classifications, their use is still limited in daily practice. If a patient needs to be centralized, the concern about possible clinical deterioration represent the main obstacle to achieving a NOM. The lack of protocols does not allow standardization of patient surveillance according to the degree of injury. The imaging follow-up is not standardized as well, varying between computed tomography, ultrasound, and contrast-enhanced ultrasound.The classification systems need to be spread to all the trauma-dedicated physicians, to speak a common language. A more rational centralization of patients should be promoted, ideally through agreements between peripheral and reference centers, both at regional and local level. Standardized protocols need to be shared nationally, as well as the clinical and imaging follow-up criteria should be adapted to the local features.

Open abdomen: is a dedicated emergency surgery team needed? A single center retrospective study on 141 consecutive patients.

BACKGROUND: Open Abdomen (OA) is widely used when facing a catastrophic abdomen. Still, no indication is validated by a strong and high quality of evidence. The study reports the 5 year experience of a dedicated emergency general surgery (EGS) team. METHODS: Retrospective observational cohort study. Patients undergoing OA management from 2/01/2015 to 19/07/2020 for trauma, non-traumatic emergencies or rescue surgery. RESULTS: One hundred and forty-one patients. Age 66.9 ± 15.1. Male 58.2%.9.3% OA for trauma, 64.5% for non-traumatic emergencies and 26.2% for rescue surgery. 40.4% performed by the EGS team 52.4% indication for surgery was a severe intra-abdominal infection. TAC device: commercial negative pressure wound therapy (NPWT) (83%), Sandwich VAC (12%), commercial NPWT with polypropylene mesh (5%) for pregressive fascial traction. Enteroatmospheric fistula (EAF) in 3 patients. OA duration 5.3 days (1-25). A 1.8 revision surgeries (0-12) required for definitive closure; ICU stay 9.9 days (0-78). 30-day mortality 23.5%. Overall and 1-year mortality were 47.5% and 43.3%. Overall survival 9.9 months. An increased one-year mortality rate was found in the >65 group (P = 0.01). CONCLUSIONS: We reported a wide use of OA in septic abdomen (90% of cases). We had a low rate of EAF, short ICU stay and OA duration. These results are related to the fact that patients were treated by a dedicated EGS team, suggesting that OA management should be cared for as much as possible by trained and experienced surgeons. Prospective studies with more accurate patient selection are needed to prove our conclusions.

Adhesive small bowel obstruction: Single band or matted adhesions? A predictive model based on computed tomography scan.

BACKGROUND: Preoperative identification of the cause of adhesive small bowel obstruction (ASBO) is crucial for decision making. Some computed tomography (CT) findings can be indicative of single adhesive bands or matted adhesions. Our aim was to build a predictive model based on CT data to discriminate ASBO due to single adhesive band or matted adhesions. METHODS: A retrospective single center study was conducted, covering all consecutive patients with a preoperative CT scan, undergoing urgent surgery for ASBO between January 1, 2005, and December 31, 2017. Preoperative CT scans were blindly reviewed, and all the CT findings indicative of single adhesive band or matted adhesions described in literature were recorded. According to intraoperative findings, ASBOs were retrospectively classified into single band and matted ASBO. All observed CT findings were compared between the two groups. A predictive model based on logistic regression was developed, and its ability was quantified by discrimination and calibration. Internal cross-validation was conducted by bootstrap resampling. RESULTS: A total of 116 patients were analyzed (males, 53.5%; median age, 68 years; single band ASBO in 65.5% of cases). The odds of single band ASBO were increased four times in presence of complete obstruction (odds ratios, 4.19; 95% confidence interval, 1.49-12.56) and seven times in presence of fat notch sign (odds ratios, 7.37; 95% confidence interval, 1.83-40.03). The predictive model combining all CT findings had an accuracy of 86% in single band ASBO prediction. Accuracy decreased to 79% in the internal validation. Sensitivity, specificity, and positive and negative predictive values were calculated at different cut-points of the predicted risk: using a 0.70 cut-point, the specificity is 80%, the sensitivity is 68%, and the positive and negative predictive values are 87% and 57%, respectively. CONCLUSION: The proposed predictive model based on combination of specific CT findings may elucidate whether ASBO is caused by single bands or matted adhesions and, consequently, influence the clinical pathway. LEVEL OF EVIDENCE: Prognostic study, level IV.

Impact of lockdown on emergency general surgery during first 2020 COVID-19 outbreak.

PURPOSE: To evaluate and analyze the impact of lockdown strategy due to coronavirus disease 2019 (COVID-19) on emergency general surgery (EGS) in the Milan area at the beginning of pandemic outbreak. METHODS: A survey was distributed to 14 different hospitals of the Milan area to analyze the variation of EGS procedures. Each hospital reported the number of EGS procedures in the same time frame comparing 2019 and 2020. The survey revealed that the number of patients during the COVID-19 pandemic outbreak in 2020 was reduced by 19% when compared with 2019. The decrease was statistically significant only for abdominal wall surgery. Interestingly, in 2020, there was an increase of three procedures: surgical intervention for acute mesenteric ischemia (p = 0.002), drainage of perianal abscesses (p = 0.000285), and cholecystostomy for acute cholecystitis (p = 0.08). CONCLUSIONS: During the first COVID-19 pandemic wave in the metropolitan area of Milan, the number of patients operated for emergency diseases decreased by around 19%. We believe that this decrease is related either to the fear of the population to ask for emergency department (ED) consultation and to a shift towards a more non-operative management in the surgeons 'decision making' process. The increase of acute mesenteric ischaemia and perianal abscess might be related to the modification of dietary habits and reduction of physical activity related to the lockdown.

Long-term results (6-10 years) of laparoscopic fundoplication.

Most papers report excellent results of laparoscopic fundoplication but with relatively short follow-up. Only few studies have a follow-up longer than 5 years. We prospectively collected data of 399 consecutive patients with gastroesophageal reflux disease (GERD) or large paraesophageal/mixed hiatal hernia who underwent laparoscopic fundoplication between January 1992 and June 2005. Preoperative workup included symptoms questionnaire, videoesophagogram, upper endoscopy, manometry, and pH-metry. Postoperative clinical/functional studies were performed at 1, 6, 12 months, and thereafter every other year. Patients were divided into four groups: GERD with nonerosive esophagitis, erosive esophagitis, Barrett's esophagus, and large paraesophageal/mixed hiatal hernia. Surgical failures were considered as follows: (1) recurrence of GERD symptoms or abnormal 24-h pH monitoring; (2) recurrence of endoscopic esophagitis; (3) recurrence of hiatal hernia/slipped fundoplication on endoscopy/barium swallow; (4) postoperative onset of dysphagia; (5) postoperative onset of gas bloating. One hundred and forty-five patients (87 M:58 F) were operated between January 1992 and June 1999: 80 nonerosive esophagitis, 29 erosive esophagitis, 17 Barrett's esophagus, and 19 large paraesophageal/mixed hiatal hernias. At a median follow-up of 97 months, the success rate was 74% for surgery only and 86% for primary surgery and 'complementary' treatments (21 patients: 13 redo surgery and eight endoscopic dilations). Dysphagia and recurrence of reflux were the most frequent causes of failure for nonerosive esophagitis patients; recurrence of hernia was prevalent among patients with large paraesophageal/mixed hiatal hernia. Gas bloating (causing failure) was reported by nonerosive esophagitis patients only. At last follow-up, 115 patients were off 'proton-pump inhibitors'; 30 were still on medications (eight for causes unrelated to GERD). Conclusion confirms that laparoscopic fundoplication provides effective, long-term treatment of gastroesophageal reflux disease. Hernia recurrence and dysphagia are its weak points.

Long-term outcome of laparoscopic Heller-Dor surgery for esophageal achalasia: possible detrimental role of previous endoscopic treatment.

Laparoscopic Heller myotomy has recently emerged as the treatment of choice for esophageal achalasia. Previous unsuccessful treatments (pneumatic dilations or botulinum toxin [BT] injections) can make surgery more difficult, causing a higher risk of mucosal perforation and jeopardizing the outcome. The study goal was to evaluate the effects of prior endoscopic treatments on laparoscopic Heller myotomy. Between January 1992 and February 2005, 248 patients (130 males and 118 females; median age, 43 years) underwent a laparoscopic Heller-Dor operation for achalasia: 203 underwent primary surgery (group A), 19 had been previously treated with pneumatic dilations (group B), and 26 had BT injections (alone [22] or with dilations [4] (group C)). Median duration of the operation and rate of intraoperative mucosal lesions were not different in the three groups. Median follow-up was 41 months. The 5-year actuarial of control of dysphagia was similar in groups A (86%) and B (94%), whereas only 75% of group C patients were symptom free at 5 years (P = 0.02). On logistic regression analysis, prior treatment with two BT injections or BT combined with dilation was associated with poor outcome of surgery. Further, dilations for surgical failure patients were effective in 80% of group A but in only 33% of group B or C patients. Heller-Dor surgery is safe and effective as a primary or a second-line treatment (after pneumatic dilations or BT injections) for achalasia. However, long-term results seem less satisfactory in patients previously treated with BT.

Barrett's epithelium after antireflux surgery.

Barrett's epithelium (BE), defined as endoscopically visible, histologically proved intestinal-type epithelium in the esophagus, is considered the ultimate consequence of long-standing gastro(duodeno)esophageal reflux disease (GERD). Recent reports suggest that effective antireflux therapy may promote the regression of this metaplastic process. This study aimed to establish whether antireflux surgery (laparoscopic fundoplication) can induce any endoscopic and/or histologic changes in BE. Thirty-five consecutive cases of BE (11 short-segment [SBE] and 24 long-segment [LBE]) were considered. All patients underwent extensive biopsy sampling before and after surgery (mean follow-up, 28 months; range, 12-99 mo). In all cases, (a) intestinal metaplasia (IM) extension (H&E), (b) IM phenotype (high-iron diamine [HID]), and (c) Cdx2 immunohistochemical expression were histologically scored in the biopsy material obtained before and after fundoplication. After surgery, a significant decrease in IM extension and a shift from incomplete- to complete-type IM were documented in SBE. No significant changes occurred in the LBE group in terms of IM extension or histochemical phenotype. A drop in the immunohistochemical expression of Cdx2 protein was also only documented in the SBE group. Antireflux surgery significantly modifies the histologic phenotype of SBE, but not of LBE.

Laparoscopic Heller-Dor for primary esophageal achalasia: outcomes in 173 patients.

AIM: Laparoscopic Heller myotomy combined with anterior (Dor) fundoplication is the most widely-used surgical procedure for treating esophageal achalasia in Europe MATERIAL OF STUDY: From November 1992 through May 2010 we performed laparoscopic Heller-Dor on 173 patients RESULTS: Conversion to laparotomy was required in three cases (1.7%) at the beginning of the experience (for mucosal) perforation which was the most frequent intraoperative complication, managed laparoscopically with the increasing experience. Five (2.9%) cases had minor postoperative complications. Clinical results were satisfactory in 99.4% of cases. One patient (0.6%) had severe persistent dysphagia. Mean esophageal diameter decreased from 50 mm ± 12 (range 20- 90) to 25 mm ± 7 (range 15-80). Lower esophageal sphincter pressure decreased from 32 mmHg (median, range 10- 93) pre-operatively to 11 mmHg (median, range 5-21) at one year follow up and residual pressure from 12 mmHg (median, range 3-30) to 4 mmHg (median, range 1-8). Impedance and pH monitoring showed normal levels in 39/47 (83%) patients who agreed to testing. CONCLUSION: The good outcomes of this experience, in part due to careful adherence to technical aspects of the operation, confirm that the laparoscopic Heller-Dor is the gold standard surgical treatment for esophageal achalasia.

Laparoscopic repair of epiphrenic diverticulum.

Epiphrenic diverticulum of the esophagus is an uncommon disease, and its pathogenesis remains unclear. Surgical repair of this disease is warranted only for symptomatic patients because treatment carries high risk of morbidity. Over the past decade, the laparoscopic approach to epiphrenic diverticulectomy has been shown to be safe and effective. The aim of the study was to describe our specific approach to the procedure and results. From 1994 to 2012, 30 patients with symptomatic epiphrenic diverticulum underwent laparoscopic surgery. There were no conversions to open surgery. The postoperative course was uneventful in 28 patients (93.3%). One patient had a suture line leak, which required repair through right thoracotomy, and 1 patient had a hemoperitoneum, which needed an open splenectomy. The median follow-up was 52 months (2-144). To date, no patient has presented with a recurrence. Laparoscopic transhiatal surgery is in our opinion the preferred approach to treatment of epiphrenic diverticulum of the esophagus. The procedure has proven to be feasible and safe in experienced hands. Long-term results, both clinical and with an objective evaluation, are satisfactory.

The preoperative manometric pattern predicts the outcome of surgical treatment for esophageal achalasia.

BACKGROUND: A new manometric classification of esophageal achalasia has recently been proposed that also suggests a correlation with the final outcome of treatment. The aim of this study was to investigate this hypothesis in a large group of achalasia patients undergoing laparoscopic Heller-Dor myotomy. METHODS: We evaluated 246 consecutive achalasia patients who underwent surgery as their first treatment from 2001 to 2009. Patients with sigmoid-shaped esophagus were excluded. Symptoms were scored and barium swallow X-ray, endoscopy, and esophageal manometry were performed before and again at 6 months after surgery. Patients were divided into three groups: (I) no distal esophageal pressurization (contraction wave amplitude <30 mmHg); (II) rapidly propagating compartmentalized pressurization (panesophageal pressurization >30 mmHg); and (III) rapidly propagating pressurization attributable to spastic contractions. Treatment failure was defined as a postoperative symptom score greater than the 10th percentile of the preoperative score (i.e., >7). RESULTS: Type III achalasia coincided with a longer overall lower esophageal sphincter (LES) length, a lower symptom score, and a smaller esophageal diameter. Treatment failure rates differed significantly in the three groups: I = 14.6% (14/96), II = 4.7% (6/127), and III = 30.4% (7/23; p = 0.0007). At univariate analysis, the manometric pattern, a low LES resting pressure, and a high chest pain score were the only factors predicting treatment failure. At multivariate analysis, the manometric pattern and a LES resting pressure <30 mmHg predicted a negative outcome. CONCLUSION: This is the first study by a surgical group to assess the outcome of surgery in 3 manometric achalasia subtypes: patients with panesophageal pressurization have the best outcome after laparoscopic Heller-Dor myotomy.

Zenker's diverticula: feasibility of a tailored approach based on diverticulum size.

BACKGROUND: Zenker's diverticula (ZD) can be treated by transoral diverticulostomy or open surgery (upper esophageal sphincter myotomy and diverticulectomy or diverticulopexy). The aim of this study was to compare the effectiveness of a minimally invasive (group A) versus a traditional open surgical approach (group B) in the treatment of ZD. MATERIAL AND METHODS: Between 1993 and September 2007, 128 ZD patients underwent transoral diverticulostomy (n = 51) or cricopharyngeal myotomy and diverticulectomy or diverticulopexy (n = 77). All patients were evaluated for symptoms using a detailed questionnaire. Manometry recorded upper esophageal sphincter (UES) pressure, relaxations, and intrabolus pharyngeal pressure. The size of the pouch was measured on the barium swallow. The choice of treatment was based on the size of the diverticulum and the patients' preference. Long-term follow-up data were available for 121/128 (94.5%) patients with a median follow-up of 40 months (interquartile range, 17-83). RESULTS: Mortality was nil. Three patients in group A (5.8%) and ten in group B (13%) had postoperative complications (p = n.s.). Hospital stays were markedly shorter for patients after diverticulostomy (p < 0.01). Postoperative manometry showed a reduction in UES pressure, improved UES relaxation, and lower intrabolus pressure in both groups (p < 0.05). Four patients in the open surgery group (5.2%) complained of severe dysphagia after surgery (three of them required endoscopic dilations). In the transoral diverticulostomy group, 11 patients (21.5%) required additional septal reduction (n = 8) or a surgical myotomy (n = 3) for persistent symptoms (p < 0.01); nine of these 11 patients had a ZD < or = 3 cm in size. After primary and complementary treatments, symptoms disappeared or improved significantly at long-term follow-up in 93.5% of patients in group A and 96% of those in group B. CONCLUSION: Diverticulostomy is safe, quick, and effective for most patients with medium-sized ZD, but open surgery offers better long-term results as a primary treatment and should be recommended for younger, healthy patients, especially those with small diverticula. Small ZD may represent a formal contraindication to the transoral approach because an excessively short septum prevents a complete division of the sphincter fibers.
