Acute cholecystitis management in high-risk, critically ill, and unfit-for-surgery patients: the Italian Society of Emergency Surgery and Trauma (SICUT) guidelines.

Dealing with acute cholecystitis in high-risk, critically ill, and unfit-for-surgery patients is frequent during daily practice and requires complex management. Several procedures exist to postpone and/or prevent surgical intervention in those patients who temporarily or definitively cannot undergo surgery. After a systematic review of the literature, an expert panel from the Italian Society of Emergency Surgery and Trauma (SICUT) discussed the different issues and statements in subsequent rounds. The final version of the statements was discussed during the annual meeting in Rome (September 2022). The present paper presents the definitive conclusions of the discussion. Fifteen statements based on the literature evidence were provided. The statements gave precise indications regarding the decisional process and the management of patients who cannot temporarily or definitively undergo cholecystectomy for acute cholecystitis. Acute cholecystitis management in high-risk, critically ill, and unfit-for-surgery patients should be multidisciplinary. The different gallbladder drainage methods must be tailored according to each patient and based on the expertise of the hospital. Percutaneous gallbladder drainage is recommended as the first choice as a bridge to surgery or in severely physiologically deranged patients. Endoscopic gallbladder drainage (cholecystoduodenostomy and cholecystogastrostomy) is suggested as a second-line alternative especially as a definitive procedure for those patients not amenable to surgical management. Trans-papillary gallbladder drainage is the last option to be reserved only to those unfit for other techniques. Delayed laparoscopic cholecystectomy in patients with percutaneous gallbladder drainage is suggested in all those patients recovering from the conditions that previously discouraged surgical intervention after at least 6 weeks from the gallbladder drainage.

Intestinal Ischemia: Unusual but Fearsome Complication of COVID-19 Infection.

The pathophysiology of gastrointestinal damage in coronavirus disease (COVID-19) is probably multifactorial. It is not clear whether the etiology of intestinal ischemia may be directly related to viral replication or may result from hyper-coagulability following SARS-CoV-2 infection.To confirm a pathogenic role of COVID-19, we retrospectively investigated the presence of SARS-CoV-2 virus in the ischemic bowel of five COVID-19 patients undergoing emergency surgery for intestinal ischemia in the period of March 2020-May 2021. Immunohistochemical positivity with weak intensity was observed in four out of five cases, but only one case was strongly positive both at immunohistochemistry and at molecular analysis. The histological alterations in the intestinal tissue samples showed similarity with the well-known alterations described in typical targetorgans of the virus (e.g., the lung). This observation suggests a similar mechanism of action of the virus. Further larger studies are, thus, required to confirm this preliminary finding. Clinicians should carefully monitor all COVID-19 patients for the possible presence of a SARS-CoV-2 intestinal infection, a potential cause of ischemia and bowel perforation.

Indocyanine Green (ICG) for the assessment of splenic perfusion during laparoscopic splenic artery aneurysmectomy. A case report.

CASE REPORT: We describe the case of a 54-year-old man with a 20mm splenic aneurysm, who underwent laparoscopic aneurysmectomy, without splenic removal. The residual splenic blood supply was assessed by using indocyanine green i.v. administration. CLINICAL FINDINGS: The patient presented at ED with abdominal pain, syncopal episode, and tachycardia. A CT scan with contrast showed hemoperitoneum with a 20mm splenic aneurysm, which was located at the bifurcation of the splenic and left gastroepiploic artery. Treatment and Outcome Laparoscopic surgery was then warranted. Abdominal exploration revealed a serohemorrhagic collection without active source of bleeding. After opening the gastro-colic ligament and obtaining vascular control of the splenic artery, the aneurysm was clipped and resected. No macroscopic modifications occurred to the spleen. This finding was confirmed by intravenous administration of indocyanine green. The operating time was 265 minutes. During the postoperative course, a grade A pancreatic fistula occurred. The patient was discharged on postoperative day seventh. CLINICAL RELEVANCE: The management of true splenic artery aneurysms should be patient-tailored, considering the location of the aneurysm, operative risks and the patient's age, life expectancy and clinical status. The use of ICG in splenic surgery helps delineate the splenic parenchyma and evaluate residual splenic vascularization. KEY WORDS: Indocyanine Green, Laparoscopy, Mini-invasive Surgery, Splenic Artery Aneurysm.

A delayed conversion may increase the risk of major complications in acute cholecystitis approached laparoscopically. A retrospective comparative cohort study.

AIM: Aim of this study was to evaluate whether timing of laparoscopy lasting longer than two hours before converting to open surgery can worsen the postoperative course during laparoscopic cholecystectomy (LC) for acute cholecystitis (AC). MATERIALS AND METHODS: Medical records of 1,161 patients who underwent urgent laparoscopic cholecystectomy for AC during the period 2001-2017 were retrospectively analyzed. A conversion to open surgery was performed in 70 (6%) patients. Among these, two groups of patients were identified: group 1 (n=51; 73%) included patients who underwent laparotomy within 2 hours from the beginning of the operation, and group 2 (n=19; 27%) included patients who underwent conversion to open surgery after more than 2 hours of laparoscopy. Patients were analyzed for demographic data and comorbidities. Major outcome measures were mortality, morbidity and length of stay. A p value < 0.05 was considered significant. RESULTS: Reasons for conversion to open surgery included severe inflammation (46%), visceral adhesions (27%), inability to manage common bile duct stones (17%), intolerance to pneumoperitoneum (7%) and the presence of a cholecystoduodenal fistula (1%). By comparing these groups, no significant differences were noted regarding overall morbidity (29% vs 42%, p=0.31), mortality (2% vs 5%, p=0.46) and mean postoperative length of stay (8.7 vs 8.2 days, p=0.75). Major postoperative complications (grade III-V according to Clavien and Dindo classification) were significantly more frequent in group 2 (p=0.03). CONCLUSIONS: When approaching AC laparoscopically, the decision to convert to open surgery within two hours may prevent the occurrence of major postoperative complications. Early conversion does not seem to affect the mortality and length of hospital stay. KEY WORDS: Acute Cholecystitis, Conversion, Laparoscopy.

Damage control surgery for perforated diverticulitis with diffuse peritonitis: saves lives and reduces ostomy.

Introduction: Over the last decade, damage control surgery (DCS) has been emerging as a feasible alternative for the management of patients with abdominal infection and sepsis. So far, there is no consensus about the role of DCS for acute perforated diverticulitis. In this study, we present the outcome of a multi-institutional series of patients presenting with Hinchey's grade III and IV diverticulitis managed by DCS. Methods: All the participating centers were tertiary referral hospitals. A total of 34 patients with perforated diverticulitis treated with DCS during the period 2011-2017 were included in the study. During the first laparotomy, a limited resection of the diseased segment was performed followed by lavage and use of negative pressure wound therapy (NPWT). After 24/48 h of resuscitation, patients returned to the operating room for a second look. Mortality, morbidity, and restoration of bowel continuity were the primary outcomes of the study. Results: There were 15 males (44%) and 19 females (56%) with a mean age of 66.9 years (SD ± 12.7). Mean BMI was 28.42 kg/m2 (SD ± 3.33). Thirteen cases (38%) were Wasvary's modified Hinchey's stage III, and 21 cases (62%) Hinchey's stage IV. Mean Mannheim Peritonitis Index (MPI) was 25.12 (SD ± 6.28). In 22 patients (65%), ASA score was ≥ grade III. Twenty-four patients (71%) had restoration of bowel continuity, while 10 (29%) patients had an end colostomy (Hartmann's procedure). Three of these patients received a temporary loop ileostomy. One patient had an anastomotic leak. Mortality rate was 12%. Mean length of hospital stay was 21.9 days. At multivariate analysis, male gender (p = 0.010) and MPI (p = 0.034) correlated with a high percentage of Hartmann's procedures. Conclusion: DCS is a feasible procedure for patients with generalized peritonitis secondary to perforated diverticulitis, and it appears to be related to a higher rate of bowel reconstruction. Due to the open abdomen, stay in ICU with prolonged mechanical ventilation is required, but these aggressive measures may be needed by most patients undergoing surgery for perforated diverticulitis, whatever the procedure is done.

Open abdomen and entero-atmospheric fistulae: An interim analysis from the International Register of Open Abdomen (IROA).

INTRODUCTION: No definitive data describing associations between cases of Open Abdomen (OA) and Entero-atmospheric fistulae (EAF) exist. The World Society of Emergency Surgery (WSES) and the Panamerican Trauma Society (PTS) thus analyzed the International Register of Open Abdomen (IROA) to assess this question. MATERIAL AND METHODS: A prospective analysis of adult patients enrolled in the IROA. RESULTS: Among 649 adult patients with OA 58 (8.9%) developed EAF. Indications for OA were peritonitis (51.2%) and traumatic-injury (16.8%). The most frequently utilized temporary abdominal closure techniques were Commercial-NPWT (46.8%) and Bogotà-bag (21.9%). Mean OA days were 7.9 ± 18.22. Overall mortality rate was 29.7%, with EAF having no impact on mortality. Multivariate analysis associated cancer (p = 0.018), days of OA (p = 0.003) and time to provision-of-nutrition (p = 0.016) with EAF occurrence. CONCLUSION: Entero-atmospheric fistulas are influenced by the duration of open abdomen treatment and by the nutritional status of the patient. Peritonitis, intestinal anastomosis, negative pressure and oral or enteral nutrition were not risk factors for EAF during OA treatment.

Laparoscopic resection of multiple aneurysms of the gastroepiploic arterial arcade.

BACKGROUND: Gastroepiploic arterial aneurysms (GEAA) represent a very rare disorder [1, 2]. The risk of GEAA rupture is high, and it is associated with a high mortality rate [3]. GEAAs are usually identified following rupture or are incidentally diagnosed. In emergency, an open surgical approach to treat GEAAs has been most frequently reported [4]. Alternatively, if the patient is hemodynamically stable, an angiography and embolization can be attempted. Herein we report the case of a patient presenting with two fissurated GEAAs that were successfully excised laparoscopically after failure of the endovascular approach. MATERIALS AND METHODS: A 83-year-old lady was admitted for acute epigastric pain. Upon admission, her general status was stable. The abdomen was soft and slightly painful at deep palpation in epigastrium, with no sign of peritonism. In her past medical history, she had a transient ischemic attack and atrial fibrillation episodes for which a pacemaker had been placed. Her blood examinations showed a slight anemia (hemoglobin 10.5 g/dl). An abdominal ultrasonography identified two solid, circular, nodules next to the gastric anterior wall that, in a following angio-TC, were diagnosed as two aneurysms of the gastro-epiploic arterial arcade (GEA), one measuring 17 mm × 13 mm, the other 39 mm × 33 mm. Both showed X-ray signs of impending rupture and intraluminal "thrombization". The patient underwent selective angiography, during which, after an attempt of common hepatic artery catheterism, a dissection and, consequently, an occlusion of the hepatic artery and the celiac trunk unfortunately occurred. Therefore, after a catetherism of the superior mesenteric artery, only a partial and incomplete embolization procedure was possible. As a matter, at the end of the angiographic procedure, reperfusion of the GEA coming from the splenic and hepatic artery was recognized. After 24 h, repeated abdominal CT scan with contrast showed the persistence of the aneurysms with no dimensional changes and the presence of a small active extravasation of contrast from the lateral aneurysm. RESULTS: Laparoscopic surgical exploration was then warranted. Two voluminous GEA arcade aneurysms, very close to greater curvature of the stomach, were identified. After a cautious visceral dissection, the right and left gastroepiploic arteries were clipped and sectioned. Due to the presence of strength adhesions between the aneurysms and the greater curvature of the stomach, we decided to perform double aneurismectomy "en bloc" with the excision of the adjacent greater gastric curve by using an articulated laparoscopic stapler (Endo GIA™ 60 mm Articulating Medium/Thick Reload with Tri-Staple™ Technology, MEDTRONIC, Minneapolis, US). No intraoperative complications were reported. The patient was discharged in fifth post-operative day. CONCLUSIONS: In case of failure of a non-surgical management of ruptured GEA aneurysms, the laparoscopic resection is a safe and effective procedure.

Less is more: an outcome assessment of patients operated for gallstone ileus without fistula treatment.

BACKGROUND: The treatment of gallstone ileus (GI) consists of surgical removal of the impacted bilestone with or without cholecystectomy and repair of the biliodigestive fistula. The objective of this study was to assess whether sparing patients a definitive biliary procedure adversely influenced the outcome. MATERIALS AND METHODS: Patients with a diagnosis of GI were reviewed. Two groups were identified: patients who underwent a definitive biliary procedure with relieving the intestinal obstruction (group 1/G1) and those who did not have a definitive biliary procedure (group 2/G2). In G2, patients were evaluated on long-term follow-up for the risk of recurrent GI disease, cholecystitis, cholangitis and gallbladder cancer. RESULTS: Among 1075 patients admitted for small bowel obstruction, 20 (1.9%) were diagnosed with gallstone ileus. 3 (15%) of these belong to G1, 17 (85%) to G2. The overall postoperative morbidity rate was 35% (7/20) with one complication exceeding grade II in each group. No deaths were reported. Mean follow-up was 50 months. During follow-up, one of G2 patients had recurrent disease. No biliary tract infections or gallbladder cancer were identified. CONCLUSION: Enterolithotomy without fistula closure is confirmed to be safe and effective for the management of gallstone ileus both on a short- and long-term basis.

Acute appendicitis complicating De Garengeot's hernia treated with combined laparoscopic-open technique: a case series and literature review.

An acute appendicitis in the context of a De Garengeot's hernia is a very rare event and represents a hard challenge for surgeons. As only few cases have been reported in literature, there is no consensus about its optimal surgical strategy of treatment. Here we present two consecutive cases of female patients presenting an uncommon acute appendicitis in a femoral hernia treated with a combined laparoscopic/open technique. KEY WORDS: Acute appendicitis, De Garengeot's hernia, Laparoscopy.

IROA: International Register of Open Abdomen, preliminary results.

BACKGROUND: No definitive data about open abdomen (OA) epidemiology and outcomes exist. The World Society of Emergency Surgery (WSES) and the Panamerican Trauma Society (PTS) promoted the International Register of Open Abdomen (IROA). METHODS: A prospective observational cohort study including patients with an OA treatment. Data were recorded on a web platform (Clinical Registers®) through a dedicated website: www.clinicalregisters.org. RESULTS: Four hundred two patients enrolled. Adult patients: 369 patients; Mean age: 57.39±18.37; 56% male; Mean BMI: 36±5.6. OA indication: Peritonitis (48.7%), Trauma (20.5%), Vascular Emergencies/Hemorrhage (9.4%), Ischemia (9.1%), Pancreatitis (4.2%),Post-operative abdominal-compartment-syndrome (3.9%), Others (4.2%). The most adopted Temporary-abdominal-closure systems were the commercial negative pressure ones (44.2%). During OA 38% of patients had complications; among them 10.5% had fistula. Definitive closure: 82.8%; Mortality during treatment: 17.2%. Mean duration of OA: 5.39(±4.83) days; Mean number of dressing changes: 0.88(±0.88). After-closure complications: (49.5%) and Mortality: (9%). No significant associations among TACT, indications, mortality, complications and fistula. A linear correlationexists between days of OA and complications (Pearson linear correlation = 0.326 p<0.0001) and with the fistula development (Pearson = 0.146 p= 0.016). Pediatric patients: 33 patients. Mean age: 5.91±(3.68) years; 60% male. Mortality: 3.4%; Complications: 44.8%; Fistula: 3.4%. Mean duration of OA: 3.22(±3.09) days. CONCLUSION: Temporary abdominal closure is reliable and safe. The different techniques account for different results according to the different indications. In peritonitis commercial negative pressure temporary closure seems to improve results. In trauma skin-closure and Bogotà-bag seem to improve results. TRIAL REGISTRATION: ClinicalTrials.gov NCT02382770.

Early cholecystectomy for non-severe acute gallstone pancreatitis: easier said than done.

BACKGROUND: Laparoscopic cholecystectomy (LC) carried out within 3 days after an attack of non-severe acute gallstone pancreatitis (NSAGP) is recommended to reduce hospital stay and overall costs. Aim of the study was to evaluate factors that may delay a timely surgical management of NSAGP and the consequences of this deviation. METHODS: We reviewed the charts of patients admitted for NSAGP and managed by LC during the last 14 years. A total number of 316 patients entered the study, 98 of whom underwent early LC. A comparison of pre-operative and outcome data from the group of patients undergone early LC and those who received a delayed LC (>3 days since the admission) was made. RESULTS: Only 31% of patients presenting with NSAGP were managed by early LC. Respect to these, patients who received a delayed LC were significantly older and had a greater occurrence of clinical signs suggesting common bile duct stones (CBDS). Stabilization of co-morbidities and need to investigate preoperatively the common duct were the main factors associated to the surgical delay. By comparing patients undergone early LC and those who received delayed LC, differences regarding conversion to open surgery (2% vs. 1.3%), need to explore the common bile duct (18.3% vs. 25.6%), CBDS clearance rates (94.4% vs. 94.6%), morbidity (8.1% vs. 8.7%), and postoperative hospital stay (3.9 vs. 3.2 days) were however statistically not significant. CONCLUSIONS: Several reasons could delay the 3-day recommendation for surgery in NSAGP. These include the need to achieve before surgery the control of age-related co morbidities, and the workup to investigate for common duct stones. A fast track program aiming to early surgery would be advisable for patients presenting with NSAGP. Compared to delayed LC, early LC appears to shorten overall hospitalization but it does not seem to have any clinical impact on the course.

An unusual case of repeated splenectomy: traumatic rupture of an accessory spleen in a previously splenectomized patient.

The traumatic rupture of an accessory spleen is a very rare condition and only few cases have been reported in the literature. We describe the case of a 51-year-old man undergone splenectomy for trauma several years before, who developed hemoperitoneum due to a laceration of a voluminous accessory spleen, following an accidental two-meter fall. As a conservative management of the injury was not possible, an accessory splenectomy was then required. Thus, a briefly review of the literature about this uncommon topic was perfomed. KEY WORDS: Accessory spleen, Laparotomy, Trauma.

Pancreatoduodenectomy for groove pancreatitis Report of two cases.

Groove pancreatitis is a rare condition with patients having clinical characteristics similar to those of chronic pancreatitis. Differentiating on clinical and radiological basis between groove pancreatitis and paraduodenal head cancer can be extremely challenging. Due to diagnostic uncertainty and to poor response to medical treatment surgery may offer these patients the best chance of cure. As the main localization of the inflammatory process is at the groove between the duodenum and the head of the pancreas, pancreato-duodenectomy is proposed as the most reliable surgical procedure. We report about two patients presenting with clinical and radiological features suggesting a groove pancreatitis in which control of symptoms was achieved by pancreatoduodenectomy. KEY WORDS: Groove pancreatitis, Paraduodenal pancreatic cancer.

Acute abdomen caused by greater omentum torsion: A case report and review of the literature.

Torsion of the greater omentum is a rare cause of acute abdomen. Based on etiopathogenesis, it can be classified as primary or secondary. However, regardless of the cause, segmentary or diffuse omental necrosis will follow. Preoperative diagnosis is not easy, though abdominal ultrasound and computed tomography (CT) scans may show peculiar features suggestive of omental torsion. Laparoscopic resection of the affected omentum is the treatment of choice. Presently reported was a case of primary omental torsion, in addition to a comprehensive literature review.

Incidental appendectomy? Microscopy tells another story: A retrospective cohort study in patients presenting acute right lower quadrant abdominal pain.

BACKGROUND: Optimal management of macroscopically normal appendix encountered during laparoscopy for acute abdominal pain is still unclear. METHODS: 164 acute abdominal pain cases in which laparoscopy showed a normal appendix were reviewed. No other intra-peritoneal acute disease was present in 50 patients (Group 1) whereas a miscellanea of intra-peritoneal conditions was identified in the other 114 (Group 2). All the patients underwent appendectomy with specimen examination. RESULTS: Following incidental appendectomy significant microscopical changes were seen in 125 specimens (76%). Among these, inflammation was found in 122 and neuroendocrine tumors in 3. Appendices harbored pathological changes in n = 45 patients (90%) of Group 1 and in n = 34 patients (70%) of Group 2 patients (p < 0.05). Morbidity for incidental appendectomy was 2%. CONCLUSION: This study supports an appendectomy in patients who are undergoing laparoscopy for acute right lower quadrant abdominal pain even when the appendix appears normal on visual inspection.

Hemoptysis caused by pulmonary sequestration in perforated appendicitis: A rare case report.

Pulmonary sequestration is a rare and usually asymptomatic congenital anomaly. Optimal management of this condition is still a subject of debate, including superiority of surgical resection or angiographic embolization of the aberrant arterial vessel. Presently described is rare case of a 51-year-old male who presented with hemoptysis related to pulmonary sequestration associated with acute right lower quadrant abdominal pain caused by perforated appendicitis.

Splenic abscess after splenic blunt injury angioembolization.

INTRODUCTION: Splenic Angioembolization (SAE), during Nonoperative Management (NOM) of Blunt Splenic Injury (BSI), is an effective therapy for hemodynamically stable patients with grade III, IV, and V OIS splenic injuries. We report a case of a patient with a blunt abdominal trauma due to an accidental fall, who presented splenic abscess a week after SAE and a review of the literature. CASE REPORT: A 38-year-old male arrived at Emergency after an accidental fall with contusion of the left upper quadrant of the abdomen. Abdominal CT scan revealed the fracture of the lower splenic pole with intraparenchymal pseudoaneurysms (OIS spleen injury scale IV). Considering the hemodynamic stability, NOM was undertaken and SAE was performed. After a week, the patient developed a splenic abscess confirmed by Abdominal CT; therefore, splenectomy was performed. There was no evidence of bacterial growing in the perisplenic hematoma cultures but the histological examination showed multiple abscess and hemorrhagic areas in the spleen. DISCUSSION: Splenic abscess after SAE during NOM of BSI is a rare major complication. The most frequently cultured organisms include Clostridium perfringens, Alpha-Hemoliticus Streptococcus, gram-positive Staphylococcus, gram-negative Salmonella, Candida, and Aspergillus. This case represents our first reported splenic abscess after SAE. CONCLUSION: SAE is a very useful tool for BSI managing; splenic abscess can occur in a short time, even if it is a rare major complication, so it may be useful to monitor patients undergoing SAE, focusing not only on the hemodynamic parameters but also on the inflammatory and infectious aspects.
