Factors affecting the number of lymph nodes retrieved after colo-rectal cancer surgery: A prospective single-centre study.

BACKGROUND: The number of harvested lymph nodes (LNs) in colorectal cancer surgery relates to oncologic radicality and accuracy of staging. In addition, it affects the choice of adjuvant therapy, as well as prognosis. The American Joint Committee on Cancer defines at least 12 LNs harvested as adequate in colorectal cancer resections. Despite the importance of the topic, even in high-volume colorectal centres the rate of adequacy never reaches 100%. The aim of this study was to identify factors that affect the number of harvested LNs in oncologic colorectal surgery. MATERIALS AND METHODS: We prospectively collected all consecutive patients who underwent colorectal cancer resection from January 1st 2013 to December 31st 2017 at Emergency Surgery Unit St Orsola University Hospital of Bologna. RESULTS: Six hundred and forty-three consecutive patients (382 elective, 261 emergency) met the study inclusion criteria. Emergency surgery and laparoscopic approach did not have a significant influence on the number of harvested LNs. The adequacy of lymphadenectomy was negatively affected by age >80 (OR 3.47, p < 0.001), ASA score ≥3 (OR 3.48, p < 0.001), Hartmann's or rectal resection (OR 3.6, p < 0.001) and R1-R2 resection margins (OR 3.9, p = 0.006), while it was positively affected by T-status ≥3 (OR 0.33 p < 0.001). CONCLUSION: Both the surgical technique and procedure regimen did not affect the number of lymphnodes retrieved. Age >80 and ASA score ≥3 and Hartmann's procedure or rectal resection showed to be risk factors related to inadequate lymphadenectomy in colorectal cancer surgery.

Antibiotic Treatment and Appendectomy for Uncomplicated Acute Appendicitis in Adults and Children: A Systematic Review and Meta-analysis.

OBJECTIVE: The aim of this meta-analysis was to summarize the current available evidence on nonoperative management (NOM) with antibiotics for uncomplicated appendicitis, both in adults and children. SUMMARY BACKGROUND DATA: Although earlier meta-analyses demonstrated that NOM with antibiotics may be an acceptable treatment strategy for patients with uncomplicated appendicitis, evidence is limited by conflicting results. METHODS: Systematic literature search was performed using MEDLINE, the Cochrane Central Register of Controlled Trials, and EMBASE databases for randomized and nonrandomized studies comparing antibiotic therapy (AT) and surgical therapy-appendectomy (ST) for uncomplicated appendicitis. Literature search was completed in August 2018. RESULTS: Twenty studies comparing AT and ST qualified for inclusion in the quantitative synthesis. In total, 3618 patients were allocated to AT (n = 1743) or ST (n = 1875). Higher complication-free treatment success rate (82.3% vs 67.2%; P < 0.00001) and treatment efficacy based on 1-year follow-up rate (93.1% vs 72.6%; P < 0.00001) were reported for ST. Index admission antibiotic treatment failure and rate of recurrence at 1-year follow-up were reported in 8.5% and 19.2% of patients treated with antibiotics, respectively. Rates of complicated appendicitis with peritonitis identified at the time of surgical operation (AT: 21.7% vs ST: 12.8%; P = 0.07) and surgical complications (AT: 12.8% vs ST: 13.6%; P = 0.66) were equivalent. CONCLUSIONS: Antibiotic therapy could represent a feasible treatment option for image-proven uncomplicated appendicitis, although complication-free treatment success rates are higher with ST. There is also evidence that NOM for uncomplicated appendicitis does not statistically increase the perforation rate in adult and pediatric patients receiving antibiotic treatment. NOM with antibiotics may fail during the primary hospitalization in about 8% of cases, and an additional 20% of patients might need a second hospitalization for recurrent appendicitis.

"To stent or not to stent?": immediate emergency surgery with laparoscopic radical colectomy with CME and primary anastomosis is feasible for obstructing left colon carcinoma.

Great debate exists in the initial acute management of large bowel obstruction from obstructing left colon carcinoma. While endoscopic stenting is well established as the first approach in the setting of palliative care of patients with advanced metastatic disease as well as a bridge to elective surgery in elderly patients who have an increased risk of postoperative mortality (age >70 years and/or ASA status ≥3), controversies exist regarding oncological safety and long-term outcomes of endoscopic colonic stenting in younger patients and ESGE Guidelines do not recommend SEMS placement in patients <70 and fit for curative surgery. Particularly, the Consensus Panelists currently state that SEMS placement as a bridge to surgery is not recommended as the standard treatment because (1) it does not reduce the postoperative mortality in the general population, (2) SEMS may be associated with an increased risk of tumor recurrence, and (3) acute resection is feasible in young and fit patients, with an acceptable postoperative mortality rate. A 32-year-old lady was admitted with complete LBO from obstructing sigmoid carcinoma. Initial i.v. CE-CT scan detected a large bowel partial obstruction with fecal impaction in the entire colon until sigmoid with some mildly dilated SB loops. The presence of a thickened area in the colonic wall could not be assessed because the patient was young and thin and in such patients the CT appearance of bowel wall cannot be clearly appreciated. She was initially managed with laxatives and gastrografin. The patient's obstruction did not improve and abdominal distension worsened with nausea and colicky pain. Urgent endoscopy detected a friable mass, consistent with completely obstructing carcinoma of the mid sigmoid. Biopsies were taken and distal ink marking was made. Whole-body urgent CT scan with i.v. contrast was performed in order to obtain full preoperative staging and to rule out distant metastases. CT scan and the previously given oral gastrografin confirmed complete large bowel obstruction with a tight stricture in the sigmoid. Cecum was markedly distended.

Application of the AAST EGS Grade for Adhesive Small Bowel Obstruction to a Multi-national Patient Population.

BACKGROUND: The American Association for the Surgery of Trauma (AAST) anatomic severity grading system for adhesive small bowel obstruction (ASBO) has demonstrated to be a valid tool in North American patient populations. Using a multi-national patient cohort, we retrospectively assessed the validity the AAST ASBO grading system and estimated disease severity in a global population in order to correlate with several key clinical outcomes. METHODS: Multicenter retrospective review during 2012-2016 from four centers, Minnesota USA, Bologna Italy, Pietermaritzburg South Africa, and Bucharest Romania, was performed. Adult patients (age ≥ 18) with ASBO were identified. Baseline demographics, physiologic parameters, laboratory results, operative and imaging details, outcomes were collected. AAST ASBO grades were assigned by independent reviewers. Univariate and multivariable analyses with odds ratio (OR) and 95% confidence intervals (CIs) were performed. RESULTS: There were 789 patients with a median [IQR] age of 58 [40-75] years; 47% were female. The AAST ASBO grades were I (n = 180, 23%), II (n = 443, 56%), III (n = 87, 11%), and IV (n = 79, 10%). Successful non-operative management was 58%. Conversion rate from laparoscopy to laparotomy was 33%. Overall mortality and complication and temporary abdominal closure rates were 2, 46, and 4.7%, respectively. On regression, independent predictors for mortality included grade III (OR 4.4 95%CI 1.1-7.3), grade IV (OR 7.4 95%CI 1.7-9.4), pneumonia (OR 5.6 95%CI 1.4-11.3), and failing non-operative management (OR 2.4 95%CI 1.3-6.7). CONCLUSION: The AAST EGS grade can be assigned with ease at any surgical facility using operative or imaging findings. The AAST ASBO severity grading system has predictive validity for important clinical outcomes and allows for standardization across institutions, providers, and future research. Disease severity and outcomes varied between countries. LEVEL OF EVIDENCE III: Study type Retrospective multi-institutional cohort study.

Current status of laparoscopy for acute abdomen in Italy: a critical appraisal of 2012 clinical guidelines from two consecutive nationwide surveys with analysis of 271,323 cases over 5 years.

BACKGROUND: Several authors have demonstrated the safety and feasibility of laparoscopy in selected cases of abdominal emergencies. The aim of the study was to analyse the current Italian practice on the use of laparoscopy in abdominal emergencies and to evaluate the impact of the 2012 national guidelines on the daily surgical activity. METHODS: Two surveys (42 closed-ended questions) on the use of laparoscopy in acute abdomen were conducted nationwide with an online questionnaire, respectively, before (2010) and after (2014) the national guidelines publication. Data from two surveys were compared using Chi-square or Fisher's exact test, and data were considered significant when p < 0.05. RESULTS: Two-hundred and one and 234 surgical units answered to the surveys in 2010 and 2014, respectively. Out of 144,310 and 127,013 overall surgical procedures, 23,407 and 20,102, respectively, were abdominal emergency operations. Respectively 24.74 % (in 2010) versus 30.27 % (in 2014) of these emergency procedures were approached laparoscopically, p = 0.42. The adoption of laparoscopy increased in all the considered clinical scenarios, with statistical significance in acute appendicitis (44 vs. 64.7 %; p = 0.004). The percentage of units approaching Hinchey III acute diverticulitis with laparoscopy in 26-75 % of cases (14.0 vs. 29.7 %; p = 0.009), those with >25 % of surgeons confident with laparoscopic approach to acute diverticulitis (29.9 vs. 54 %; p = 0.0009), the units with >50 % of surgeons confident with laparoscopic approach to acute appendicitis, cholecystitis and perforated duodenal ulcer, all significantly increased in the time frame. The majority of respondents declared that the 2012 national guidelines influenced their clinical practice. CONCLUSIONS: The surveys showed an increasing use of laparoscopy for patients with abdominal emergencies. The 2012 national guidelines profoundly influenced the Italian surgical practice in the laparoscopic approach to the acute abdomen.

IPOD Study: Management of Acute Left Colonic Diverticulitis in Italian Surgical Departments.

BACKGROUND: In recent years, the emergency management of acute left colonic diverticulitis (ALCD) has evolved dramatically despite lack of strong evidence. As a consequence, management strategies are frequently guided by surgeon's personal preference, rather than by scientific evidence. The primary aim of IPOD study (Italian Prospective Observational Diverticulitis study) is to describe both the diagnostic and treatment profiles of patients with ALCD in the Italian surgical departments. METHODS: IPOD study is a prospective observational study performed during a 6-month period (from April 1 2015 to September 1 2015) and including 89 Italian surgical departments. All consecutive patients with suspected clinical diagnosis of ALCD confirmed by imaging and seen by a surgeon were included in the study. The study was promoted by the Italian Society of Hospital Surgeons and the World Society of Emergency Surgery Italian chapter. RESULTS: Eleven hundred and twenty-five patients with a median age of 62 years [interquartile range (IQR), 51-74] were enrolled in the IPOD study. One thousand and fifty-four (93.7%) patients were hospitalized with a median duration of hospitalization of 7 days (IQR 5-10). Eight hundred and twenty-eight patients (73.6%) underwent medical treatment alone, 13 patients had percutaneous drainage (1.2%), and the other 284 (25.2%) patients underwent surgery as first treatment. Among 121 patients having diffuse peritonitis, 71 (58.7%) underwent Hartmann's resection. However, the Hartmann's resection was used even in patients with lower stages of ALCD (36/479; 7.5%) where other treatment options could be more adequate. CONCLUSIONS: The IPOD study demonstrates that in the Italian surgical departments treatment strategies for ALCD are often guided by the surgeon's personal preference.

Pushing the envelope: laparoscopy and primary anastomosis are technically feasible in stable patients with Hinchey IV perforated acute diverticulitis and gross faeculent peritonitis.

INTRODUCTION: Modern management of severe acute complicated diverticulitis continues to evolve towards more conservative and minimally invasive strategies. Although open sigmoid colectomy with end colostomy remains the most commonly used procedure for the treatment of perforated diverticulitis with purulent/faeculent peritonitis, recent major advances challenged this traditional approach, including the increasing attitude towards primary anastomosis as an alternative to end colostomy and use of laparoscopic approach for urgent colectomy. TECHNIQUE: Provided an accurate patients selection, having the necessary haemodynamic stability, pneumoperitoneum is established with open Hasson technique and diagnostic laparoscopy is performed. If faeculent peritonitis (Hinchey IV perforated diverticulitis) is found, laparoscopy can be continued and a further three working ports are placed using bladeless trocars, as in traditional laparoscopic sigmoidectomy, with the addition of fourth trocar in left flank. The feacal matter is aspirated either with large-size suction devices or, in case of free solid stools, these can be removed with novel application of tight sealing endobags, which can be used for scooping the feacal content out and for its protected retrieval. After decontamination, a sigmoid colectomy is performed in the traditional laparoscopic fashion. The sigmoid is fully mobilised from the retroperitoneum, and mesocolon is divided up to the origin of left colic vessels. Whenever mesentery has extremely inflamed and thickened oedematous tissues, an endostapler with vascular load can be used to avoid vascular selective ligatures. Splenic flexure should be appropriately mobilised. The specimen is extracted through mini-Pfannenstiel incision with muscle splitting technique. Transanal colo-rectal anastomosis is fashioned. Air-leak test must be performed and drains placed where appropriate. RESULTS: The video shows operative technique for a single-stage, entirely laparoscopic, washout and sigmoid colectomy with primary colorectal anastomosis in a 35-year-old male patient with severe and diffuse free faeculent diverticular peritonitis (Hinchey IV). The patient was managed post-operatively according to enhanced recovery protocol and discharged home after 9 days, following an uneventful recovery. CONCLUSIONS: This case documents the technical feasibility of a minimally invasive single-stage procedure in a patient with Hinchey IV perforated diverticulitis with diffuse feacal peritonitis. The laparoscopic approach facilitated an effective decontamination of the peritoneal cavity, with a combination of large suction devices and aid of protected retrieval by closed endobags for effectively and completely laparoscopic removal of the solid feacal matter, offering clear advantages and excellent results even in such challenging cases. With necessary expertise, the sigmoid resection can be thereafter safely and entirely performed laparoscopically, the specimen extracted through mini-Pfannenstiel incision, and a laparoscopic intracorporeal transanal circular primary anastomosis performed.

Classification, prevention and management of entero-atmospheric fistula: a state-of-the-art review.

BACKGROUND: Entero-atmospheric fistula (EAF) is an enteric fistula occurring in the setting of an open abdomen, thus creating a communication between the GI tract and the external atmosphere. Management and nursing of patients suffering EAF carries several challenges, and prevention of EAF should be the first and best treatment option. PURPOSE: Here, we present a novel modified classification of EAF and review the current state of the art in its prevention and management including nutritional issues and feeding strategies. We also provide an overview on surgical management principles, highlighting several surgical techniques for dealing with EAF that have been reported in the literature throughout the years. CONCLUSIONS: The treatment strategy for EAF should be multidisciplinary and multifaceted. Surgical treatment is most often multistep and should be tailored to the single patient, based on the type and characteristics of the EAF, following its correct identification and classification. The specific experience of surgeons and nursing staff in the management of EAF could be enhanced, applying distinct simulation-based ex vivo training models.

The 2023 WSES guidelines on the management of trauma in elderly and frail patients.

BACKGROUND: The trauma mortality rate is higher in the elderly compared with younger patients. Ageing is associated with physiological changes in multiple systems and correlated with frailty. Frailty is a risk factor for mortality in elderly trauma patients. We aim to provide evidence-based guidelines for the management of geriatric trauma patients to improve it and reduce futile procedures. METHODS: Six working groups of expert acute care and trauma surgeons reviewed extensively the literature according to the topic and the PICO question assigned. Statements and recommendations were assessed according to the GRADE methodology and approved by a consensus of experts in the field at the 10th international congress of the WSES in 2023. RESULTS: The management of elderly trauma patients requires knowledge of ageing physiology, a focused triage, including drug history, frailty assessment, nutritional status, and early activation of trauma protocol to improve outcomes. Acute trauma pain in the elderly has to be managed in a multimodal analgesic approach, to avoid side effects of opioid use. Antibiotic prophylaxis is recommended in penetrating (abdominal, thoracic) trauma, in severely burned and in open fractures elderly patients to decrease septic complications. Antibiotics are not recommended in blunt trauma in the absence of signs of sepsis and septic shock. Venous thromboembolism prophylaxis with LMWH or UFH should be administrated as soon as possible in high and moderate-risk elderly trauma patients according to the renal function, weight of the patient and bleeding risk. A palliative care team should be involved as soon as possible to discuss the end of life in a multidisciplinary approach considering the patient's directives, family feelings and representatives' desires, and all decisions should be shared. CONCLUSIONS: The management of elderly trauma patients requires knowledge of ageing physiology, a focused triage based on assessing frailty and early activation of trauma protocol to improve outcomes. Geriatric Intensive Care Units are needed to care for elderly and frail trauma patients in a multidisciplinary approach to decrease mortality and improve outcomes.

Laparoscopic Hartmann's reversal has better clinical outcomes compared to open surgery: An international multicenter cohort study involving 502 patients.

Background: Hartmann's procedure (HP) is used in surgical emergencies such as colonic perforation and colonic obstruction. "Temporary" colostomy performed during HP is not always reversed in part due to potential morbidity and mortality associated with reversal. There are several contributing factors for patients requiring a permanent colostomy following HP. Therefore, there is still some discussion about which technique to use. The aim of this study was to evaluate perioperative variables of patients undergoing Hartmann's reversal using a laparoscopic and open approach. Methods: The multicenter retrospective cohort study was done between January 2009 and December 2019 at 14 institutions globally. Patients who underwent Hartmann's reversal laparoscopic (LS) and open (OS) approaches were evaluated and compared. Sociodemographic, preoperative, intraoperative variables, and surgical outcomes were analyzed. The main outcomes evaluated were 30-day mortality, length of stay, complications, and postoperative outcomes. Results: Five hundred and two patients (264 in the LS and 238 in the OS group) were included. The most prevalent sex was male in 53.7%, the most common indication was complicated diverticular disease in 69.9%, and 85% were American Society of Anesthesiologist (ASA) II-III. Intraoperative complications were noted in 5.3% and 3.4% in the LS and OS groups, respectively. Small bowel injuries were the most common intraoperative injury in 8.3%, with a higher incidence in the OS group compared with the LS group (12.2% vs. 4.9%, p < 0.5). Inadvertent injuries were more common in the small bowel (3%) in the LS group. A total of 17.2% in the OS versus 13.3% in the LS group required intensive care unit (ICU) admission (p = 0.2). The most frequent postoperative complication was ileus (12.6% in OS vs. 9.8% in LS group, p = 0.4)). Reintervention was required mainly in the OS group (15.5% vs. 5.3% in LS group, p < 0.5); mortality rate was 1%. Conclusions: Laparoscopic Hartmann's reversal is safe and feasible, associated with superior clinical outcomes compared with open surgery.

Laparoscopic splenectomy as a definitive management option for high-grade traumatic splenic injury when non operative management is not feasible or failed: a 5-year experience from a level one trauma center with minimally invasive surgery expertise.

Technique, indications and outcomes of laparoscopic splenectomy in stable trauma patients have not been well described yet. All hemodynamically non-compromised abdominal trauma patients who underwent splenectomy from 1/2013 to 12/2017 at our Level 1 trauma center were included. Demographic and clinical data were collected and analysed with per-protocol and an intention-to-treat comparison between open vs laparoscopic groups. 49 splenectomies were performed (16 laparoscopic, 33 open). Among the laparoscopic group, 81% were successfully completed laparoscopically. Laparoscopy was associated with a higher incidence of concomitant surgical procedures (p 0.016), longer operative times, but a significantly faster return of bowel function and oral diet without reoperations. No significant differences were demonstrated in morbidity, mortality, length of stay, or long-term complications, although laparoscopic had lower surgical site infection (0 vs 21%).The isolated splenic injury sub-analysis included 25 splenectomies,76% (19) open and 24% (6) laparoscopic and confirmed reduction in post-operative morbidity (40 vs 57%), blood transfusion (0 vs 48%), ICU admission (20 vs 57%) and overall LOS (7 vs 9 days) in the laparoscopic group. Laparoscopic splenectomy is a safe and effective technique for hemodynamically stable patients with splenic trauma and may represent an advantageous alternative to open splenectomy in terms of post-operative recovery and morbidity.

Is the minimally invasive trauma surgeon the next (r)evolution of trauma surgery? Indications and outcomes of diagnostic and therapeutic trauma laparoscopy in a level 1 trauma centre.

The aim of this study was to evaluate the trend in use, feasibility and safety of laparoscopy in a single level 1 European trauma centre. Laparoscopy in abdominal trauma is gaining acceptance as a diagnostic and a therapeutic tool as it reduces surgical invasiveness and may reduce post-operative morbidity. All trauma patients who underwent a laparoscopic procedure between January 2013 and December 2017 were retrospectively analysed. A sub-analysis of isolated abdominal trauma was also performed. There has been a significant increase in the use of this technique in the considered time period. A total of 40 patients were included in the study: 17 diagnostic laparoscopies and overall 32 therapeutic laparoscopies. Conversion rate was 15%. All patients were hemodynamically stable. The majority of patients were younger than 60 years, with an ASA score of I-II and sustained a blunt trauma. Mean ISS score was 17. Colon and diaphragm were the most commonly laparoscopically diagnosed injuries, while splenectomy was the most common operation. The average operating time was 106 min. There were no missed injuries, no SSI, no re-interventions and no mortality related to the surgical procedure. The average length of stay was 14 days. No significant difference was found in the isolated abdominal trauma group. Laparoscopy is an emergent safe and effective technique for both diagnostic and therapeutic purposes in selected stable abdominal penetrating or blunt trauma patients. However, these results need to be put in relation with the level of the centre and the expertise of the surgeon.

Diagnosis and treatment of acute appendicitis: 2020 update of the WSES Jerusalem guidelines.

BACKGROUND AND AIMS: Acute appendicitis (AA) is among the most common causes of acute abdominal pain. Diagnosis of AA is still challenging and some controversies on its management are still present among different settings and practice patterns worldwide. In July 2015, the World Society of Emergency Surgery (WSES) organized in Jerusalem the first consensus conference on the diagnosis and treatment of AA in adult patients with the intention of producing evidence-based guidelines. An updated consensus conference took place in Nijemegen in June 2019 and the guidelines have now been updated in order to provide evidence-based statements and recommendations in keeping with varying clinical practice: use of clinical scores and imaging in diagnosing AA, indications and timing for surgery, use of non-operative management and antibiotics, laparoscopy and surgical techniques, intra-operative scoring, and peri-operative antibiotic therapy. METHODS: This executive manuscript summarizes the WSES guidelines for the diagnosis and treatment of AA. Literature search has been updated up to 2019 and statements and recommendations have been developed according to the GRADE methodology. The statements were voted, eventually modified, and finally approved by the participants to the consensus conference and by the board of co-authors, using a Delphi methodology for voting whenever there was controversy on a statement or a recommendation. Several tables highlighting the research topics and questions, search syntaxes, and the statements and the WSES evidence-based recommendations are provided. Finally, two different practical clinical algorithms are provided in the form of a flow chart for both adults and pediatric (< 16 years old) patients. CONCLUSIONS: The 2020 WSES guidelines on AA aim to provide updated evidence-based statements and recommendations on each of the following topics: (1) diagnosis, (2) non-operative management for uncomplicated AA, (3) timing of appendectomy and in-hospital delay, (4) surgical treatment, (5) intra-operative grading of AA, (6) ,management of perforated AA with phlegmon or abscess, and (7) peri-operative antibiotic therapy.

Outcomes and indications for emergency thoracotomy after adoption of a more liberal policy in a western European level 1 trauma centre: 8-year experience.

The role of emergency thoracotomy (ET) in blunt trauma is still a matter of debate and in Europe only a small number of studies have been published. We report our experience about ET both in penetrating and blunt trauma, discussing indications, outcomes and proposing an algorithm for patient selection. We retrospectively analysed patients who underwent ET at Maggiore Hospital Trauma Center over two periods: from January 1st, 2010 to December 31st, 2012, and from January 1st, 2013 to May 31st, 2017. Demographic and clinical data, mechanism of injury, Injury Severity Score, site of injury, time of witnessed cardiac arrest, presence/absence of signs of life, length of stay were considered, as well as survival rate and neurological outcome. 27 ETs were performed: 21 after blunt trauma and 6 after penetrating trauma. Motor vehicle accident was the main mechanism of injury, followed by fall from height. The mean age was 40.5 years and the median Injury Severity Score was of 40. The most frequent injury was cardiac tamponade. The overall survival rate was 10% during the first period and 23.5% during the second period, after the adoption of a more liberal policy. No long-term neurological sequelae were reported. The outcomes of ET in trauma patient, either after penetrating or blunt trauma, are poor but not negligible. To date, only small series of ET from European trauma centres have been published, although larger series are available from USA and South Africa. However, in selected patients, all efforts must be made for the patient's survival; the possibility of organ donation should be taken into consideration as well.

Laparoscopic versus open adhesiolysis for adhesive small bowel obstruction (LASSO): an international, multicentre, randomised, open-label trial.

BACKGROUND: Although laparoscopic adhesiolysis for adhesive small bowel obstruction is being done more frequently, it is not widely accepted due to the lack of supporting evidence of its superiority over an open approach and concerns regarding its benefits. We aimed to investigate whether laparoscopic adhesiolysis was a superior treatment for adhesive small bowel obstruction compared with an open approach in terms of length of postoperative hospital stay and morbidity. METHODS: In this international, multicentre, parallel, open-label trial, we randomly assigned patients (1:1) aged 18-95 years who had adhesive small bowel obstruction that had not resolved with conservative management to have either open or laparoscopic adhesiolysis. The study was done in five academic university hospitals and three community (central) hospitals in two countries (Finland [n=3 academic university hospitals; n=3 community hospitals] and Italy [n=2 academic university hospitals]). We included only patients with high likelihood of a single adhesive band in the trial; additionally, patients who had an anaesthesiological contraindication, were pregnant, living in institutionalised care, or who had a hospital stay of more than 1 week before the surgical consultation were excluded from the trial. The randomisation sequence was generated using block randomisation, with randomly varied block sizes and stratified according to centre. The primary outcome was postoperative length of hospital stay assessed at time of discharge in the modified intention-to-treat population. FINDINGS: Between July 18, 2013, and April 9, 2018, 566 patients were assessed for eligibility, of whom 104 patients were randomly assigned to the open surgery group (n=51) or to the laparoscopy group (n=53). Of these patients, 100 were included in the modified intention-to-treat analyses (49 in the open surgery group; 51 in the laparoscopy group). The postoperative length of hospital stay for open surgery group was on average 1·3 days longer than that in the laparoscopy group (geometric mean 5·5 days [range 2-19] vs 4·2 days [range 1 -20]; ratio of geometric means 1·31 [95% CI 1·06-1·61]; p=0·013). 21 (43%) patients in the open surgery group and 16 (31%) patients in the laparoscopy group had postoperative complications (Clavien-Dindo any grade) within 30 days (odds ratio 0·61 [95% CI 0·27-1·38]; p=0·23). One patient died in each group within 30 days. INTERPRETATION: Laparoscopic adhesiolysis provides quicker recovery in selected patients with adhesive small bowel obstruction than open adhesiolysis.

Laparoscopy for Trauma and the Changes in its Use From 1990 to 2016: A Current Systematic Review and Meta-Analysis.

BACKGROUND: The role of laparoscopy in the diagnosis and treatment of stable abdominal trauma patients is still a matter of serious debate and only incomplete data are available. MATERIALS AND METHODS: We performed a systematic review and meta-analysis of the literature between January 1990 and August 2016. RESULTS: Overall, 9817 laparoscopies were performed for abdominal trauma; only 26.2% of the cases were converted to a laparotomy. The incidence of therapeutic laparotomies showed a reduction from 69% to 47.5%, whereas the incidence of therapeutic laparoscopies increased from 7.2% to 22.7%.The overall perioperative mortality rate was significantly lower in the laparoscopy group [odds ratio (M-H, random); 95% confidence interval, 0.35 (0.26-0.48)]. The same group showed shorter length of hospital stay [odds ratio (M-H, random); 95% confidence interval, -3.48 (-8.91 to 1.96)]. CONCLUSIONS: This systematic review shows a significant decrease in the use of laparoscopy in trauma patients. Most likely the widespread use of imaging techniques allows a more accurate selection of patients for diagnostic laparoscopy. Infact, a reduction in incidence of nontherapeutic laparotomies is evident in these selected patients undergoing diagnostic laparoscopy. Moreover, the literature reported an increasing trend of therapeutic laparoscopy, demonstrating that it is safe and effective. The small number and poor quality of the studies identified, the retrospective observational nature of the studies (low level of evidence), the high risk of bias, and the high heterogeneity of some outcomes make the applicability of the results of this meta-analysis unclear.
