Goodbye Hartmann trial: a prospective, international, multicenter, observational study on the current use of a surgical procedure developed a century ago.

BACKGROUND: Literature suggests colonic resection and primary anastomosis (RPA) instead of Hartmann's procedure (HP) for the treatment of left-sided colonic emergencies. We aim to evaluate the surgical options globally used to treat patients with acute left-sided colonic emergencies and the factors that leading to the choice of treatment, comparing HP and RPA. METHODS: This is a prospective, international, multicenter, observational study registered on ClinicalTrials.gov. A total 1215 patients with left-sided colonic emergencies who required surgery were included from 204 centers during the period of March 1, 2020, to May 31, 2020. with a 1-year follow-up. RESULTS: 564 patients (43.1%) were females. The mean age was 65.9 ± 15.6 years. HP was performed in 697 (57.3%) patients and RPA in 384 (31.6%) cases. Complicated acute diverticulitis was the most common cause of left-sided colonic emergencies (40.2%), followed by colorectal malignancy (36.6%). Severe complications (Clavien-Dindo ≥ 3b) were higher in the HP group (P < 0.001). 30-day mortality was higher in HP patients (13.7%), especially in case of bowel perforation and diffused peritonitis. 1-year follow-up showed no differences on ostomy reversal rate between HP and RPA. (P = 0.127). A backward likelihood logistic regression model showed that RPA was preferred in younger patients, having low ASA score (≤ 3), in case of large bowel obstruction, absence of colonic ischemia, longer time from admission to surgery, operating early at the day working hours, by a surgeon who performed more than 50 colorectal resections. CONCLUSIONS: After 100 years since the first Hartmann's procedure, HP remains the most common treatment for left-sided colorectal emergencies. Treatment's choice depends on patient characteristics, the time of surgery and the experience of the surgeon. RPA should be considered as the gold standard for surgery, with HP being an exception.

Botulinum Toxin and Progressive Pneumoperitoneum in Loss of Domain Ventral Hernias: A Systematic Review.

Introduction: Preoperative progressive pneumoperitoneum (PPP) and botulinum toxin A (BTX) have been used together in the preoperative preparation of patients with loss of domain hernias. This study aims to evaluate the efficacy and safety of the combined use of PPP and BTX. Methods: A systematic electronic search was performed according to the PRISMA criteria. A literature search of scientific articles was conducted up to December 2023. Articles were chosen based on the reference to BTX and PPP in loss of domain ventral hernias with a defect width greater than 10 cm before surgery. The GRADE methodology and the modified Newcastle-Ottawa scale were used to assess the quality of the studies. Results: The research yielded seven articles, with 217 patients analysed in total. BTX was performed 29.5 ± 1.7 days before surgery and PPP was inflated 14.8 ± 5.8 days before surgery. PPP complications were reported in 25.6% of patients, The average reduction of the volume of hernia (VH)/volume of the abdominal cavity (VAC) ratio was 7.6% (range 0.9%-15%). Only 40 patients (18.4%) required a PCS or TAR to repair the loss of domain hernias. The SSI and SSO rates were 17.5% and 26.2%, respectively. No differences in SSI and SSO rates were found between the different repair techniques. The recurrence rate was 5.9% (13/217). Recurrence was significantly higher in patients who underwent IPOM repair than other techniques (p < 0.001). Conclusion: BTX and PPP may be useful tools for the management of loss of domain hernias presenting lower SSI and SSO. The combination of BTX and PPP reduces the use of more invasive repair techniques.

Are Surgeons Going to Be Left Holding the Bag? Incisional Hernia Repair and Intra-Peritoneal Non-Absorbable Mesh Implant Complications.

Ventral incisional hernias are common indications for elective repair and frequently complicated by recurrence. Surgical meshes, which may be synthetic, bio-synthetic, or biological, decrease recurrence and, resultingly, their use has become standard. While most patients are greatly benefited, mesh represents a permanently implanted foreign body. Mesh may be implanted within the intra-peritoneal, preperitoneal, retrorectus, inlay, or onlay anatomic positions. Meshes may be associated with complications that may be early or late and range from minor to severe. Long-term complications with intra-peritoneal synthetic mesh (IPSM) in apposition to the viscera are particularly at risk for adhesions and potential enteric fistula formation. The overall rate of such complications is difficult to appreciate due to poor long-term follow-up data, although it behooves surgeons to understand these risks as they are the ones who implant these devices. All surgeons need to be aware that meshes are commercial devices that are delivered into their operating room without scientific evidence of efficacy or even safety due to the unique regulatory practices that distinguish medical devices from medications. Thus, surgeons must continue to advocate for more stringent oversight and improved scientific evaluation to serve our patients properly and protect the patient-surgeon relationship as the only rationale long-term strategy to avoid ongoing complications.

The Challenge of Pneumatosis Intestinalis: A Contemporary Systematic Review.

PURPOSE: Pneumatosis intestinalis is a radiological finding with incompletely understood pathogenesis. To date, there are no protocols to guide surgical intervention. METHODS: A systematic review of literature, according to PRISMA criteria, was performed. Medline and PubMed were consulted to identify articles reporting on the items "emergency surgery, pneumatosis coli, and pneumatosis intestinalis" from January 2010 up to March 2022. This study has not been registered in relevant databases. RESULTS: A total of 1673 patients were included. The average age was 67.1 ± 17.6 years. The etiology was unknown in 802 (47.9%) patients. Hemodynamic instability (246/1673-14.7% of the patients) was associated with bowel ischemia, necrosis, or perforation (p = 0.019). Conservative management was performed in 824 (49.2%) patients. Surgery was performed 619 (36.9%) times, especially in unstable patients with bowel ischemia signs, lactate levels greater than 2 mmol/L, and PVG (p = 0.0026). In 155 cases, surgery was performed without pathological findings. CONCLUSIONS: Many variables should be considered in the approach to patients with pneumatosis intestinalis. The challenge facing the surgeons is in truly identifying those who really would benefit and need surgical intervention. The watch and wait policy as a first step seems reasonable, reserving surgery only for patients who are unstable or with high suspicion of bowel ischemia, necrosis, or perforation.

Management of complicated diaphragmatic hernia in the acute setting: a WSES position paper.

BACKGROUND: Diaphragmatic hernia (DH) presenting acutely can be a potentially life-threatening condition. Its management continues to be debatable. METHODS: A bibliographic search using major databases was performed using the terms "emergency surgery" "diaphragmatic hernia," "traumatic diaphragmatic rupture" and "congenital diaphragmatic hernia." GRADE methodology was used to evaluate the evidence and give recommendations. RESULTS: CT scan of the chest and abdomen is the diagnostic gold standard to evaluate complicated DH. Appropriate preoperative assessment and prompt surgical intervention are important for a clinical success. Complicated DH repair is best performed via the use of biological and bioabsorbable meshes which have proven to reduce recurrence. The laparoscopic approach is the preferred technique in hemodynamically stable patients without significant comorbidities because it facilitates early diagnosis of small diaphragmatic injuries from traumatic wounds in the thoraco-abdominal area and reduces postoperative complications. Open surgery should be reserved for situations when skills and equipment for laparoscopy are not available, where exploratory laparotomy is needed, or if the patient is hemodynamically unstable. Damage Control Surgery is an option in the management of critical and unstable patients. CONCLUSIONS: Complicated diaphragmatic hernia is a rare life-threatening condition. CT scan of the chest and abdomen is the gold standard for diagnosing the diaphragmatic hernia. Laparoscopic repair is the best treatment option for stable patients with complicated diaphragmatic hernias. Open repair is considered necessary in majority of unstable patients in whom Damage Control Surgery can be life-saving.

Conservative management of complicated colonic diverticulitis: long-term results.

BACKGROUND: The management of recurrent diverticulitis after initial non-operative treatment remains controversial. Recurrences after medical treatment have been described up to 36% but only 3 to 5% develop complicated disease. AIM: To investigate the effectiveness of conservative treatment during a prolonged follow-up after first episode of complicated diverticulitis. METHODS: This retrospective single-center study describes the conservative management and outcomes of 207 with complicated acute colonic diverticulitis treated at Parma University Hospital from 1 January 2012 until 31 December 2019. The follow-up was performed until December 2020. Diverticulitis severity was staged according to WSES CT driven classification for acute diverticulitis. RESULTS: We enrolled 207 patients (118 males, 89 females). The mean age was 59 ± 14.5 years. CT scan of the abdomen was always performed. Almost all patients were treated with bowel rest and antibiotics (98.5%). Percutaneous drainage of abscessed diverticulitis was performed 12 times (5.7%). Average follow-up was 48 ± 28.8 months. 79 patients had new episodes of diverticulitis (38.1%) and 23 patients had high severity new episodes (11.1%). 11 patients underwent surgery (7.7%). Lower CT-Stages showed a higher recurrence rate (P = 0.002). Grade III diverticulitis showed a lower recurrence rate (P = 0.007). Patients with chronic NSAID use showed a higher incidence of high severity new episodes (P = 0.039). No recurrence rate differences were noted among patients with or without home therapy (P > 0.05). CONCLUSIONS: Non-operative treatment is an effective and safe option in selected patients with complicated diverticulitis. The recurrence's severity is generally lower than the previous episodes and this can justify the conservative management.

Anorectal emergencies: WSES-AAST guidelines.

Anorectal emergencies comprise a wide variety of diseases that share common symptoms, i.e., anorectal pain or bleeding and might require immediate management. While most of the underlying conditions do not need inpatient management, some of them could be life-threatening and need prompt recognition and treatment. It is well known that an incorrect diagnosis is frequent for anorectal diseases and that a delayed diagnosis is related to an impaired outcome. This paper aims to improve the knowledge and the awareness on this specific topic and to provide a useful tool for every physician dealing with anorectal emergencies.The present guidelines have been developed according to the GRADE methodology. To create these guidelines, a panel of experts was designed and charged by the boards of the World Society of Emergency Surgery (WSES) and American Association for the Surgery of Trauma (AAST) to perform a systematic review of the available literature and to provide evidence-based statements with immediate practical application. All the statements were presented and discussed during the WSES-AAST-WJES Consensus Conference on Anorectal Emergencies, and for each statement, a consensus among the WSES-AAST panel of experts was reached. We structured our work into seven main topics to cover the entire management of patients with anorectal emergencies and to provide an up-to-date, easy-to-use tool that can help physicians and surgeons during the decision-making process.

Open abdomen in the management of complicated diaphragmatic hernia: a case report.

Diaphragmatic hernia (DH) can be congenital or acquired. DH is a potentially life-threatening condition and the management in emergency setting remain unclear. Nonspecific symptoms can delay the diagnosis. We report a case of a 63-year-old man admitted for abdominal pain and nausea. He was successfully treated with damage control surgery.

Jejunal diverticulitis: Things to know to prevent diagnostic mistake.

We report a peculiar case of jejunal diverticulitis in 54-year-old female. Since hospital admission, a colonic diverticulitis was suspected. CT scan of the abdomen showed multiple fluid collections with free intraperitoneal extraluminal air, suggesting bowel perforation. A complicated acute diverticulitis of the colon was suspected but intraoperatively, a perforated acute diverticulitis of jejunum was detected. The aim of this work is to evidence the key role of CT scan of the abdomen in differential diagnosis of unfrequently pathological entities, such as jejunal diverticulitis, to prevent diagnostic mistakes.

Thoracic complications from retained abdominal gallstones after laparoscopic cholecystectomy: is it always mandatory a thoracic approach?

BACKGROUND: Thoracic complications from retained abdominal gallstones are quite rare and the incidence rate ranges between 0.08% and 0.3%. Diagnosis and treatment of these complications are challenging due to the uncommon presentations and the debated role of the thoracic approach. This review of all cases reported in literature aims to discuss the best practice of this rare condition. METHODS: A comprehensive literature search was performed for articles from January 1993 to May 2019 using PubMed, MEDLINE, Embase, ScienceDirect. The following mesh-words were used: 'cholelithopthysis', 'thoracic', 'gallstones' 'retained', and 'spilled'. All cases of thoracic complications from retained gallstones after laparoscopic cholecystectomy were extrapolated. RESULTS: Twenty-four patients were included in this study. The most common symptoms were fever, hemoptysis and lithoptysis. Symptoms after laparoscopic cholecystectomy were presented after a mean time of 9.8±14.2 months (range from one week to 60 months). Delayed diagnosis was found in fourteen patients (58.4.%). Only four subjects were treated successfully with antibiotic therapy alone (16.7%), whereas 20 patients needed surgery or interventional radiology (83.3%). Seven patients (29.2%) were successfully managed with an abdominal approach. Three patients were managed using thoracentesis, thoracoscopic-thoracotomic drainage (12.5%). Right lung decortication and pulmonary wedge resections were necessary for ten patients (41.6%). CONCLUSION: Clinicians always must inquire about the previous cholecystectomy for cholelithiasis related diseases in all patients suffering from recurrent right-sided pleural/lung affections, to improve diagnostic delay. The escalated approach must be performed: empirical antimicrobial therapy followed by targeted therapy as soon as microbiological data are available; afterwards, abdominal surgery is effective in approximately 30% of patients while the remaining patients have to be submitted to a thoracic approach.

The critical view of safety during laparoscopic cholecystectomy: Strasberg Yes or No? An Italian Multicentre study.

BACKGROUND: Laparoscopic cholecystectomy is considered the gold standard for the treatment of gallbladder lithiasis; nevertheless, the incidence of bile duct injuries (BDI) is still high (0.3-0.8%) compared to open cholecystectomy (0.2%). In 1995, Strasberg introduced the "Critical View of Safety" (CVS) to reduce the risk of BDI. Despite its widespread use, the scientific evidence supporting this technique to prevent BDI is controversial. METHODS: Between March 2017 and March 2019, the data of patients submitted to laparoscopic cholecystectomy in 30 Italian surgical departments were collected on a national database. A survey was submitted to all members of Italian Digestive Pathology Society to obtain data on the preoperative workup, the surgical and postoperative management of patients and to judge, at the end of the procedure, if the isolation of the elements was performed according to the CVS. In the case of a declared critical view, iconographic documentation was obtained, finally reviewed by an external auditor. RESULTS: Data from 604 patients were analysed. The study population was divided into two groups according to the evidence (Group A; n = 11) or absence (Group B; N = 593) of BDI and perioperative bleeding. The non-use of CVS was found in 54.6% of procedures in the Group A, and 25.8% in the Group B, and evaluating the operator-related variables the execution of CVS was associated with a significantly lower incidence of BDI and intraoperative bleeding. CONCLUSIONS: The CVS confirmed to be the safest technique to recognize the elements of the Calot triangle and, if correctly performed, it significantly impacted on preventing intraoperative complications. Additional educational programs on the correct application of CVS in clinical practice would be desirable to avoid extreme conditions that may require additional procedures.

Conservative Management of Complicated Colonic Diverticulitis in Early and Late Elderly.

Background and Objectives: The management of complicated diverticulitis in the elderly can be a challenge and initial non-operative treatment remains controversial. In this study, we investigate the effectiveness of conservative treatment in elderly people after the first episode of complicated diverticulitis. Materials and Methods: This retrospective single-centre study describes 71 cases of elderly patients with complicated acute colonic diverticulitis treated with conservative management at Parma University Hospital from 1 January 2012 to 31 December 2019. Diverticulitis severity was staged according to WSES CT driven classification for acute diverticulitis. Patients was divided into two groups: early (65-74 yo) and late elderly (>75 yo). Results: We enrolled 71 elderly patients conservatively treated for complicated acute colonic diverticulitis, 25 males and 46 females. The mean age was 74.78 ± 6.8 years (range 65-92). Localized abdominal pain and fever were the most common symptoms reported in 34 cases (47.88%). Average white cells count was 10.04 ± 5.05 × 109/L in the early elderly group and 11.24 ± 7.89 in the late elderly group. CRP was elevated in 29 (78.3%) cases in early elderly and in 23 late elderly patients (67.6%). A CT scan of the abdomen was performed in every case (100%). Almost all patients were treated with bowel rest and antibiotics (95.7%). Average length of stay was 7.74 ± 7.1 days (range 1-48). Thirty-day hospital readmission and mortality were not reported. Average follow-up was 52.32 ± 31.8 months. During follow-up, home therapy was prescribed in 48 cases (67.6%). New episodes of acute diverticulitis were reported in 20 patients (28.1%), elevated WBC and chronic NSAID therapy were related to a higher risk of recurrence in early elderly patients (p < 0.05). Stage IIb-III with elevated WBC during first episode, had a higher recurrence rate compared to the other CT-stage (p = 0.006). Conclusions: The management of ACD in the elderly can be a challenge. Conservative treatment is safe and effective in older patients, avoiding unnecessary surgery that can lead to unexpected complications due to co-morbidities.

Operating Room Setup: How to Improve Health Care Professionals Safety During Pandemic COVID-19-A Quality Improvement Study.

Background: COVID-19 is a terrific pandemic and a potential risk for every health care professional (HCP), especially during emergency conditions where the right timing is essential for the correct treatment. During surgery the correct setting of operative room (OR) is mandatory to reduce the risk of contamination. Personal protection equipment (PPE), specific devices, and planned OR setting are essential during surgery in pandemic COVID-19. Methods: Medline, PubMed, Scientific societies recommendations, and guidelines were consulted to identify articles reporting the setup of OR during pandemic COVID-19. Results: OR must have a high-efficiency particulate air (HEPA) filter with negative pressure and a high air exchange cycle rate. Every supply kit should be packed and placed in the OR before patient arrival. A detailed checklist of equipment and devices is necessary. Personal PPE at the highest level should be provided to every HCP (Association of the Advancement of Medical Instrumentation [AAMI]-Level-III surgical gowns; double latex-free gloves with Acceptable Quality Level <1.0; FFP3 or powered air-purifying respirator masks with face shield). Anesthesia should be performed with a rapid sequence intubation. During surgery energy devices should be settled to the lower level in combination with a smoke evacuation switch pen with disposable smoke evacuation HEPA filter to minimize surgical smoke spread. During laparoscopy low pneumoperitoneum pressures and aspiration systems must be provided. Conclusions: Emergency surgery during pandemic COVID-19 increases the risk for every HCP in the OR. A theoretical risk of transmission from the surgical field exists. It is mandatory the adoption of strong strategies to reduce the risk of contamination in the OR.

Complicated Diaphragmatic Hernia in Emergency Surgery: Systematic Review of the Literature.

INTRODUCTION: Complicated diaphragmatic hernia (DH) can be congenital or acquired. Congenital diaphragmatic hernias (CDH) are rare and often can be asymptomatic until adulthood. Traumatic diaphragmatic hernia (TDH) is a complication that occurs in about 1-5% of victims of road accidents and in 10-15% of penetrating traumas of the lower chest. CDH and TDH are potentially life-threatening conditions, and the management in emergency setting still debated. This study aims to evaluate the surgical treatment options in emergency setting. METHODS: A bibliographic research reporting the item "emergency surgery" linked with "traumatic diaphragmatic rupture" and "congenital diaphragmatic hernia" was performed. Several parameters were recorded including sex, age, etiology, diagnosis, treatment, site and herniated organs. RESULTS: The research included 146 articles, and 1542 patients were analyzed. Most of the complicated diaphragmatic hernias occurred for a diaphragmatic defect due to trauma, only 7.2% occurred for a congenital diaphragmatic defect. The main diagnostic method used was chest X-ray and CT scan. Laparotomic approach still remains predominant compared to the minimally invasive approach. CONCLUSION: Surgery is the treatment of choice and is strongly influenced by the preoperative setting, performed mainly with X-ray and CT scan. Minimally invasive approach is safe and feasible but is highly dependent on the surgeon's expertise, especially in emergency setting.

Management of intra-abdominal-infections: 2017 World Society of Emergency Surgery guidelines summary focused on remote areas and low-income nations.

BACKGROUND: Most remote areas have restricted access to healthcare services and are too small and remote to sustain specialist services. In 2017, the World Society of Emergency Surgery (WSES) published guidelines for the management of intra-abdominal infections. Many hospitals, especially those in remote areas, continue to face logistical barriers, leading to an overall poorer adherence to international guidelines. METHODS: The aim of this paper is to report and amend the 2017 WSES guidelines for the management of intra-abdominal infections, extending these recommendations for remote areas and low-income countries. A literature search of the PubMed/MEDLINE databases was conducted covering the period up until June 2020. RESULTS: The critical shortages of healthcare workers and material resources in remote areas require the use of a robust triage system. A combination of abdominal signs and symptoms with early warning signs may be used to screen patients needing immediate acute care surgery. A tailored diagnostic step-up approach based on the hospital's resources is recommended. Ultrasound and plain X-ray may be useful diagnostic tools in remote areas. The source of infection should be totally controlled as soon as possible. CONCLUSIONS: The cornerstones of effective treatment for intra-abdominal infections in remote areas include early diagnosis, prompt resuscitation, early source control, and appropriate antimicrobial therapy. Standardization in applying the guidelines is mandatory to adequately manage intra-abdominal infections.

Hey surgeons! It is time to lead and be a champion in preventing and managing surgical infections!

Appropriate measures of infection prevention and management are integral to optimal clinical practice and standards of care. Among surgeons, these measures are often over-looked. However, surgeons are at the forefront in preventing and managing infections. Surgeons are responsible for many of the processes of healthcare that impact the risk for surgical site infections and play a key role in their prevention. Surgeons are also at the forefront in managing patients with infections, who often need prompt source control and appropriate antibiotic therapy, and are directly responsible for their outcome. In this context, the direct leadership of surgeons in infection prevention and management is of utmost importance. In order to disseminate worldwide this message, the editorial has been translated into 9 different languages (Arabic, Chinese, French, German, Italian, Portuguese, Spanish, Russian, and Turkish).

Surgery in COVID-19 patients: operational directives.

The current COVID-19 pandemic underlines the importance of a mindful utilization of financial and human resources. Preserving resources and manpower is paramount in healthcare. It is important to ensure the ability of surgeons and specialized professionals to function through the pandemic. A conscious effort should be made to minimize infection in this sector. A high mortality rate within this group would be detrimental.This manuscript is the result of a collaboration between the major Italian surgical and anesthesiologic societies: ACOI, SIC, SICUT, SICO, SICG, SIFIPAC, SICE, and SIAARTI. We aim to describe recommended clinical pathways for COVID-19-positive patients requiring acute non-deferrable surgical care. All hospitals should organize dedicated protocols and workforce training as part of the effort to face the current pandemic.

Perforated and bleeding peptic ulcer: WSES guidelines.

Background: Peptic ulcer disease is common with a lifetime prevalence in the general population of 5-10% and an incidence of 0.1-0.3% per year. Despite a sharp reduction in incidence and rates of hospital admission and mortality over the past 30 years, complications are still encountered in 10-20% of these patients. Peptic ulcer disease remains a significant healthcare problem, which can consume considerable financial resources. Management may involve various subspecialties including surgeons, gastroenterologists, and radiologists. Successful management of patients with complicated peptic ulcer (CPU) involves prompt recognition, resuscitation when required, appropriate antibiotic therapy, and timely surgical/radiological treatment. Methods: The present guidelines have been developed according to the GRADE methodology. To create these guidelines, a panel of experts was designed and charged by the board of the WSES to perform a systematic review of the available literature and to provide evidence-based statements with immediate practical application. All the statements were presented and discussed during the 5th WSES Congress, and for each statement, a consensus among the WSES panel of experts was reached. Conclusions: The population considered in these guidelines is adult patients with suspected complicated peptic ulcer disease. These guidelines present evidence-based international consensus statements on the management of complicated peptic ulcer from a collaboration of a panel of experts and are intended to improve the knowledge and the awareness of physicians around the world on this specific topic. We divided our work into the two main topics, bleeding and perforated peptic ulcer, and structured it into six main topics that cover the entire management process of patients with complicated peptic ulcer, from diagnosis at ED arrival to post-discharge antimicrobial therapy, to provide an up-to-date, easy-to-use tool that can help physicians and surgeons during the decision-making process.

Intestinal duplications: incidentally ileum duplication cyst in young female.

Gastrointestinal tract duplication is a rare congenital malformation in young patients and in adults, that occur anywhere from the mouth to the anus and their macroscopic structure may be cystic or tubular. Intestinal duplication does not show specific symptoms, indeed they can present with a variety of symptoms including abdominal distension and pain, sickness, hemorrhage, chronic respiratory disorders, as well as non-painful abdominal mass. Nonetheless, intestinal duplication can remain completely asymptomatic and be diagnosed as an incidental finding. Presentation with acute complications such as intestinal invagination or mechanical occlusion is quite rare. We present a case of asymptomatic ileum duplication cyst in young female who referred to the emergency department for trauma and was screened by eco-Focus Assessment Sonography for Trauma (eco-FAST), followed by MR and CT. The patient underwent ileal resection and prophylactic appendicectomy with ileo-cecal termino-lateral anastomosis. In this case, the intestinal duplication cyst was an asymptomatic incidental finding.
