RESUMO

INTRODUCTION: Several articles have been published about the reorganisation of surgical activity during the COVID-19 pandemic but few, if any, have focused on the impact that this has had on emergency and trauma surgery. Our aim was to review the most current data on COVID-19 to provide essential suggestions on how to manage the acute abdomen during the pandemic. METHODS: A systematic review was conducted of the most relevant English language articles on COVID-19 and surgery published between 15 December 2019 and 30 March 2020. FINDINGS: Access to the operating theatre is almost exclusively restricted to emergencies and oncological procedures. The use of laparoscopy in COVID-19 positive patients should be cautiously considered. The main risk lies in the presence of the virus in the pneumoperitoneum: the aerosol released in the operating theatre could contaminate both staff and the environment. CONCLUSIONS: During the COVID-19 pandemic, all efforts should be deployed in order to evaluate the feasibility of postponing surgery until the patient is no longer considered potentially infectious or at risk of perioperative complications. If surgery is deemed necessary, the emergency surgeon must minimise the risk of exposure to the virus by involving a minimal number of healthcare staff and shortening the occupation of the operating theatre. In case of a lack of security measures to enable safe laparoscopy, open surgery should be considered.

RESUMO

Acute calculus cholecystitis is a very common disease with several area of uncertainty. The World Society of Emergency Surgery developed extensive guidelines in order to cover grey areas. The diagnostic criteria, the antimicrobial therapy, the evaluation of associated common bile duct stones, the identification of "high risk" patients, the surgical timing, the type of surgery, and the alternatives to surgery are discussed. Moreover the algorithm is proposed: as soon as diagnosis is made and after the evaluation of choledocholitiasis risk, laparoscopic cholecystectomy should be offered to all patients exception of those with high risk of morbidity or mortality. These Guidelines must be considered as an adjunctive tool for decision but they are not substitute of the clinical judgement for the individual patient.

RESUMO

AIM: Laparoscopic adhesiolysis has been demonstrated to be technically feasible in small bowel obstruction and carries advantages in terms of post-surgical course. The increasing dissemination of laparoscopic surgery in the emergency setting and the lack of concrete evidence in the literature have called for a consensus conference to draw recommendations for clinical practice. METHODS: A literature search was used to outline the evidence, and a consensus conference was held between experts in the field. A survey of international experts added expertise to the debate. A public jury of surgeons discussed and validated the statements, and the entire process was reviewed by three external experts. RESULTS: Recommendations concern the diagnostic evaluation, the timing of the operation, the selection of patients, the induction of the pneumoperitoneum, the removal of the cause of obstructions, the criteria for conversion, the use of adhesion-preventing agents, the need for high-technology dissection instruments and behaviour in the case of misdiagnosed hernia or the need for bowel resection. CONCLUSION: Evidence of this kind of surgery is scanty because of the absence of randomized controlled trials. Nevertheless laparoscopic skills in emergency are widespread. The recommendations given with the consensus process might be a useful tool in the hands of surgeons.

RESUMO

INTRODUCTION: Early restored patency of the papilla has been hypothesized to reduce complications and mortality of acute biliary pancreatitis. The aim of this study was to evaluate the role of urgent laparoscopic cholecystectomy with intraoperative cholangiography and rendezvous when necessary in acute biliary pancreatitis natural history. PATIENTS AND METHODS: Patients observed in the early stage of an acute biliary pancreatitis were included in the study. Operative risk assessment based on American Society of Anesthesiologists (ASA) score allowed the performance of urgent laparoscopic cholecystectomy within 72 h from onset of symptoms in 55 patients and a delayed intervention during the same admission in 21 patients. Intraoperative cholangiography was performed in all cases, and clearance of common bile duct was performed by flushing when possible, or rendezvous when necessary. Evolution of pancreatitis was evaluated with clinical and radiological monitoring. RESULTS: Urgent laparoscopic cholecystectomy was performed in all cases without conversion. At intraoperative cholangiography common bile duct was free in 25 patients, a papillary spasm was observed in 9, and common bile duct stones in 21 patients. Patency of the papilla was restored by flushing in 13 patients, while a rendezvous was necessary in 17 patients. The rate of organ failure and pancreatic necrosis was 1.8%, overall mortality was 1.8%, and overall morbidity 21.8%. No infectious complications of peripancreatic collections were observed. CONCLUSION: Urgent laparoscopic cholecystectomy with selective intraoperative rendezvous may be considered as a treatment option in the early stage of acute biliary pancreatitis.

RESUMO

AIM: Infiltration of the superior vena cava (SVC) due to advanced non small cell lung cancer (NSCLC) or thymoma can be treated by prosthetic replacement or tangential resection. These two technical procedures and their results are described. METHODS: From 1988 to 2002, we performed 37 SVC resections: 21 replacements with polytetrafluoroethylene (PTFE) prostheses and 16 tangential exereses. Sixteen patients affected by locally advanced NSCLC (12 T4; 4 extracapsular N2) and 5 subjects with thymoma (Stage III Masaoka) underwent prosthetic replacement of the SVC. After neoadjuvant polychemotherapy, tangential resection was performed on 12 patients with extracapsular N2 NSCLC, and in 1 patient with T4 and in 3 patients with T3a disease. We performed prosthetic replacement in 18 cases using a straight prosthesis (?18-20 mm). A bridge (10-14 cm) between the innominate vein and the right atrium was created in 3 patients. The main indication for a prosthetic replacement was infiltration of more than 30% of the circumference of the SVC. There were 4 thromboembolic complications (19%), with one intraoperative death (4.8%). Tangential resection of the SVC for infiltration <20% was performed both manually and with staplers (double clamping) without any major complications. RESULTS: Mean survival was 23 months in those patients who had undergone PTFE replacement for T4 lung cancer and for thymoma. Mean survival was 15 months in those who had undergone tangential resections for NSCLC with extracapsular N2. We performed restaging of the tumor using chest angio-CT scan in 11 patients, one year after the operation. We found 80% patency in 7 SVC prostheses and 50% patency in 4 others: the two bridges between the left innominate vein and the right atrium appeared to be partially closed but were compensated by important collateral circles. CONCLUSION: SVC replacement, associated with pulmonary resection or removal of mediastinal masses, can be performed in selected cases. It should not be considered as palliative treatment because of the important perioperative risks. SVC tangential resection involves fewer surgical problems. However, since this procedure is used mostly for N2 NSCLC subjects, patients have a low mean survival in spite of adjuvant therapy.

RESUMO

BACKGROUND: Although laparoscopy in general surgery is increasingly being performed, only recently has liver surgery been performed with laparoscopy. We critically review our experience with laparoscopic liver resections. METHODS: From January 2000 to April 2004, we performed laparoscopic hepatic resection in 16 patients with 18 hepatic lesions. Nine lesions were benign in seven patients (five hydatid cysts, three hemangiomas, and one simple cyst), five were malignant in five patients (five hepatocarcinoma), and four patients had an uncertain preoperative diagnosis (one suspected hemangioma and three suspected adenomas). The mean lesion size was 5.2 cm (range, 1-12). Twelve lesions were located in the left lobe, three were in segment VI, one was in segment V, one was in segment IV, and one was in the subcapsular part of segment VIII. RESULTS: The conversion rate was 6.2%; intraoperative bleeding requiring blood transfusions occurred in two patients. Mean operative time was 120 min. Mean hospital stay was 4 days (range, 2-7). There were no major postoperative complications and no mortality. CONCLUSIONS: Hepatic resection with laparoscopy is feasible in malignant and benign hepatic lesions located in the left lobe and anterior inferior right lobe segments (IV, V, and VI). Results are similar to those of the open surgical technique in carefully selected cases, although studies with large numbers of patients are necessary to drawn definite conclusions.

RESUMO

BACKGROUND: Emergency laparoscopic exploration can be used to identify the causative pathology of acute abdominal pain. Laparoscopic surgery also allows treatment of many intraabdominal disorders. This report was prepared to describe the effectiveness of laparoscopic surgery compared to laparotomy or nonoperative treatment. METHODS: A panel of European experts in abdominal and gynecological surgery was assembled and participated in a consensus conference using Delphi methods. The aim was to develop evidence-based recommendations for the most common diseases that may cause acute abdominal pain. RECOMMENDATIONS: Laparoscopic surgery was found to be clearly superior for patients with a presumable diagnosis of perforated peptic ulcer, acute cholecystitis, appendicitis, or pelvic inflammatory disease. In the emergency setting, laparoscopy is of unclear or limited value if adhesive bowel obstruction, acute diverticulitis, nonbiliary pancreatitis, hernia incarceration, or mesenteric ischemia are suspected. In stable patients with acute abdominal pain, noninvasive diagnostics should be fully exhausted before considering explorative surgery. However, diagnostic laparoscopy may be useful if no diagnosis can be found by conventional diagnostics. More clinical data are needed on the use of laparoscopy after blunt or penetrating trauma of the abdomen. CONCLUSIONS: Due to diagnostic and therapeutic advantages, laparoscopic surgery is useful for the majority of conditions underlying acute abdominal pain, but noninvasive diagnostic aids should be exhausted first. Depending on symptom severity, laparoscopy should be advocated if routine diagnostic procedures have failed to yield results.

RESUMO

BACKGROUND: Some authors have assessed the feasibility of laparoscopy in the treatment of postoperative adhesive obstruction, but conclusions about its effectiveness are related to different selection criteria used for surgery. This paper reports on our experience in laparoscopic adhesiolysis and analyses the results on the basis of the selection criteria used. METHODS: From January 1993 to December 2001, 65 patients were submitted to laparoscopic adhesiolysis for small bowel obstruction according to specific selection criteria. Of the 65 patients, 40 were admitted for acute obstruction and 25 for chronic or recurrent transit disturbances. Correlation between historical and clinical data and the results of surgical treatment were statistically analyzed. RESULTS: The procedure was completed by laparoscopy in 52 patients (conversion rate: 20%). Mean postoperative stay was 4.4 days with a 12.3% morbidity and no mortality. Recurrence rate was 15.4%; a single correlation was found between recurrence and age. CONCLUSIONS: Laparoscopic adhesiolysis in the treatment of small bowel obstructions seems to be effective; further studies are required to define selection criteria for surgery and confirm real advantages in terms of recurrences.

RESUMO

BACKGROUND: The incidence of paraaortic lymph node metastasis (N4) in relation with the site of the tumour, and survival in patients with gastric cancer who underwent gastric resection and superextended lymphadenectomy (D4), have been analyzed. METHODS: The frequency of paraaortic lymph node metastasis was studied in 132 patients who underwent gastrectomy with D4 lymphadenectomy during the period June 1988 - December 2000. Six patients with plastic linitis and 3 with carcinoma of the gastric stump were excluded from the analysis. RESULTS: In personal experience the most frequent postoperative morbidity were respiratory complication (7.6%) and pancreatic fistula (6.8%). Among the 132 patients the total number of dissected nodes was 6362 and the mean number of dissected nodes per case was 48.2. The total number of retrieved lymph nodes from the paraaortic station was 755 with a mean number 5.7 per patients. N4 nodal involvement was found in 25 (19%) of 132 patients: 14 (36%) patients with carcinoma located in the proximal third, 5 (13%) with tumour located in the middle third and 6 (11%) with carcinoma of the distal third of the stomach. The median survival time and the overall cumulative 5-year survival rate for curatively (R0) resected patients were 74 months and 52% respectively. CONCLUSIONS: The presence of metastasis in paraaortic lymph nodes in 19% of our patients, the low morbidity and mortality, the good survival after superextended lymphadenectomy, suggest that this lymphadenectomy should be considered in the curative surgical treatment of advanced gastric cancer, especially if located in the proximal third of the stomach (N4 in 36% of cases).

RESUMO

BACKGROUND: To assess an additional prognostic value of Goseki histological classification to TNM staging system in adenocarcinoma of the cardia. METHODS: Sixty-one patients curatively resected for advanced (T2, T3 and T4) cardia cancer at the I Division of General Surgery, University of Verona were classified in four different grades according to Goseki. Survival curves were estimated with Kaplan-Meier method and compared by the log-rank test. Multivariate analysis was performed by Cox regression model. c2 test was used to compare Goseki to Lauren classification and grading. After discharge from hospital all patients were followed with a mean follow-up of 39.5 months. RESULTS: Lauren classification and grading were significantly related to tubular differentiation (p<0.01). Kaplan-Meier estimates of survival showed a better 5-year outcome for tumors with good tubular differentiation (19%), even though the difference with poor tubular differentiated tumors was not statistically significant (p'0.06). Diffuse type carcinomas and tumors with poor cytological differentiation showed a worse prognosis at univariate analysis (p<0.01). Multivariate analysis showed no additional prognostic significance of any of the histological classification analyzed. Only T (p<0.02; RR 2.2; IC 1.2-4) and N (p<0.01; RR 5; IC 2.4-11) were independent prognostic factors. CONCLUSIONS: In adenocarcinoma of the cardia, Goseki classification did not add any information to Lauren classification and to TNM staging system.

RESUMO

The Authors reported the results of surgical treatment of acute gallstone cholecystitis (AGC) in patients in whom different selection criteria have been applied. Two-hundred-eighty patients with a clinical and/or ultrasonographic diagnosis of ALC were admitted to the 1st Division of General Surgery-University of Verona Italy between January 1992 and June 2001, the patients were divided into five groups according to clinical features, laboratory tests and echographic signs. A specific approach was used in the different groups. An urgent laparoscopic cholecystectomy was performed in 67 patients. Elective laparoscopic treatment after urgent US guided percutaneous cholecystostomy (US-PC) was performed in 119 and after US-PC and ERCP in 50 patients. Laparoscopic cholecystectomy was performed in 236 patients with a conversion rate of 7.6%. No mortality, 6.7% morbidity and a mean hospital stay of 7.5 days. A selective therapeutic approach to AGC allow immediate treatment in all cases and correct diagnosis of associated diseases treatment. This approach makes it possible to reduce the conversion rate of laparoscopic cholecystectomy, morbidity and mortality.

RESUMO

AIM OF THE STUDY: The aim of this study is to evaluate the results of acute gallstone pancreatitis treatment and to discuss indications in relation with the different forms of the disease. MATERIAL AND METHOD: From january 1992 to june 2001, 137 patients have been treated for an acute gallstone pancreatitis. Diagnostic criteria were given by the history, clinical examination, biochemical and radiological findings. After exclusion of patients with a systemic disease, a group of 129 patients have been enrolled in a treatment regimen with an endoscopic retrograde cholangiopancreatography (ERCP) and eventual sphincterotomy, a percutaneous US-guided cholecystostomy (PC) when necessary and an elective laparoscopic cholecystectomy. RESULTS: ERCP has been successfully performed in 121/129 patients. A PC has been performed in 5/8 patients of the failed endoscopic procedure and in 14 with acute cholecystitis. Retrograde and percutaneous cholangiographies showed main bile duct stones in 89 patients, a dilatation of the main bile duct without stones in 26 patients and a negative finding in 6 patients. An endoscopic sphincterotomy has been performed in 117 patients. A laparoscopic cholecystectomy has been performed in 118 patients. Mortality and morbidity rates were 1.6 and 10.3%, respectively. CONCLUSION: ERCP and sphincterotomy seem to be indicated in all patients observed during the first 72 hours. Endoscopic treatment and percutaneous procedure make it possible to reduce at a very low rate the cases with an unfavourable course of the disease. A definitive treatment may then be performed by the way of a laparoscopic cholecystectomy.

RESUMO

BACKGROUND: In order to improve the accuracy in the assessment of depth of tumor invasion, we performed an ultrasound examination of the resected specimen intraoperatively just after removal by the surgeon (Intraoperative Ultrasonography (IUS). This prospective blind study reports the results obtained with the IUS in the staging of T in a group of 281 patients who underwent curative gastrectomy for gastric cancer. METHODS: After the removal by the surgeon, the portion of the stomach harboring the tumor was submitted to ultrasonography with a linear 7.5 Mhz probe. An echo-free standoff pad was placed between the probe and the organ; a second echo-free standoff pad was interposed between the stomach and the support surface. The diagnosis of depth of invasion was based on the degree of disruption of the five-layer sonographic structure of the gastric wall. RESULTS: The IUS staging of T corresponded to the pathological diagnosis in 256 out of 281 cases (overall accuracy 91.1%). The sensitivity in the different classes of T was, respectively, 91.2 in T1m cases, 83.3 in the T1sm cases, 89.6 in the T2 cases, and 93.5% in the T3 cases. CONCLUSION: The IUS on the resected specimen has a high degree of accuracy in the assessment of depth of tumor invasion and seems to be an important advance in the clinical staging of gastric cancer.

RESUMO

AIMS: To determine the significance of superextended lymphadenectomy (D4) in patients with gastric cancer. The incidence of para-aortic lymph node metastases (N4) was analysed as well as its relationship to the site of the tumour. PATIENTS AND METHODS: The frequency of para-aortic lymph node metastases was assessed in 110 patients who underwent gastrectomy with D4 lymphadenectomy during the period from June 1988 to October 1999; five patients with plastic linitis and three with carcinoma of the gastric stump were excluded from the study. RESULTS: The postoperative mortality rate was 2.7% (n = 3) and the postoperative morbidity rate was 29.1% (n = 32). In our experience the most frequent postoperative complications were pancreatic fistulas (7.3%) and respiratory complications (6.4%). Among the 110 patients, the total number of dissected nodes was 5245 and the mean number of dissected nodes per case was 47.7. The total number of retrieved lymph nodes from the para-aortic station level was 639, with a mean number of 5.8 per patient. N4 nodal involvement was found in 20 (18.2%) out of 110 patients: 12 (33%) patients with a carcinoma located in the proximal third, two (6%) with a tumour located in the middle third and six (15%) with a carcinoma of the distal third of the stomach. CONCLUSION: The presence of para-aortic lymph node involvement in 18.2% of the patients suggests that D4 lymphadenectomy should be considered in the curative surgical treatment of advanced gastric cancer, especially if located in the proximal third of the stomach (N4 + in 33% of the patients).

RESUMO

The aim of the study was to verify the long term results obtained in primary gastric lymphoma with a strategy consisting in surgery as first-line treatment. Over the period from January 1988 to December 1999, 44 patients with histologically proven primary gastric lymphoma underwent surgical treatment in the First Department of General Surgery of the University of Verona. Tumours were staged according to the Ann Arbor classification and divided, according to the Kiel classification, into high- and low-grade lymphoma. Patients received adjuvant chemotherapy depending on the grade of malignancy and/or completeness of resection. Of the 44 patients, 40 (90.9%) underwent curative resections, i.e. with complete macroscopic and microscopic tumour removal (R0), consisting in total gastrectomy in 34 cases and subtotal gastrectomy in 6. Twenty-five of 40 patients had stage IE and 15 stage IIE tumours. Adjuvant chemotherapy was given to 33 patients (30 high-grade lymphomas and 3 low-grade lymphomas with N2 metastases). The overall cumulative 10-year survival rate in patients who underwent R0 resection was 79% without any significant differences in 10-year survival between patients with high- and low-grade malignancy (both 79%; P = 0.582) or between patients with or without lymph node metastases (91% and 70%, respectively; P = 0.426). In conclusion, the present investigation suggests that surgery yields prolonged complete remission in a high percentage of patients affected by gastric lymphoma irrespective of histopathologic grade of the disease and nodal involvement.

RESUMO

BACKGROUND AND STUDY AIMS: For several years now there has been an increasingly widespread use of a tissue adhesive in the treatment of bleeding gastric varices to achieve rapid, safe control of hemostasis and prevent rebleeding. In this study we report on our experience with the use of Bucrylate (Hystoacryl) for the treatment of gastric varices over a period of more than a decade. PATIENTS AND METHODS: Since 1988, 174 cirrhotic patients with actively bleeding gastric varices have been admitted to our department, where they received emergency treatment with injections of Bucrylate. Any associated nonbleeding esophageal varices were subjected to traditional sclerotherapy in combination with the Bucrylate treatment. The gastric varices were subdivided into four distinct groups according to the method advocated by Sarin in 1989. The patients underwent weekly sclerotherapy sessions until their varices were eradicated, and the follow-up with a mean of 36 months (range 9-90 months) consisted of endoscopy at 3, 6, and 12 months during the first year and then yearly checks to confirm obliteration of the varices. RESULTS: The hemostasis (97.1%), early rebleeding (15.5%), and hospital mortality (19.5%) rates of the patients with bleeding gastric varices, treated with the tissue adhesive, were very similar to those of patients treated for esophageal varices over the same period (98.1%, 13.0%, and 16.4%, respectively). The most frequent cause of death at 30 days was liver failure (76% of cases), followed by hemorrhagic shock (8.8%), and other less frequent causes. Sclerotherapy achieved obliteration rate for gastric varices (70-75%) similar to that for esophageal varices in those patients with portal hypertension due to intrahepatic block (alcoholic and posthepatitis cirrhosis), but a rate of only 32% in the group of patients with prehepatic block (splenoportomesenteric thrombosis), where surgery proved more effective (69%). The medium- and long-term survival rates depended on the stability of the patients' liver conditions, on rapid, effective control of variceal hemostasis, and on complete, lasting obliteration of the gastric varices. CONCLUSIONS: The use of Bucrylate in emergency sclerotherapy achieved results in bleeding gastric varices on a par with those obtained in esophageal varices in cases of alcoholic and posthepatitis cirrhosis. The group of patients with portal hypertension due to prehepatic block (splenoportal thrombosis) showed no benefit from sclerotherapy in terms of obliteration of gastric varices, but benefited from elective surgery. The choice of the obliterating treatment indicated may be facilitated by classifying gastric varices into distinct groups on the basis of anatomicotopographic criteria.

RESUMO

BACKGROUND: The aim of the present study was to evaluate the incidence of abdominal lymph node involvement of adenocarcinoma of the gastric cardia in relationship with the site and depth of tumor invasion. METHODS: From July 1988 to April 1998, 79 patients with adenocarcinoma of the gastric cardia underwent surgical curative resection and D2 lymphadenectomy at the 1st Department of General Surgery of Verona University. Among these 79 patients, 16 had an adenocarcinoma of the distal esophagus (type I), 26 patients had an adenocarcinoma of the anatomic cardia (type II) and 37 had a subcardial adenocarcinoma (type III). The frequency of lymph node involvement in each of the lymph nodes as classified by the JRSGC were analyzed. RESULTS: In type I carcinoma positive lymph nodes occurred in 20% of pT1, 33% of pT2 and 100% of pT3. Positive nodes along the lower half of the stomach were never found. In type II carcinoma positive lymph nodes occurred in 57% of pT1, 86% of pT2 and 83% of pT3. Metastasis along the greater curvature in 18% of advanced cancers were found. In type III carcinoma positive lymph nodes occurred in 83% of pT2, 94% of pT3 and in 100% of pT4. Nodes along greater curvature were involved in 21% of advanced cases and also infrapyloric lymph nodes involved in 13% of cases. The type II and III advanced tumors had involved paraortic lymph node in 33% of cases. CONCLUSIONS: These results suggest that for tumors of the cardia an extended lymphadenectomy is necessary to ensure the removal of all metastatic nodes.

RESUMO

BACKGROUND: The morbidity and mortality rates associated with acute cholecystitis are higher in the elderly. This study reports the results of treatment of acute cholecystitis in the elderly with emergency ultrasonographically guided percutaneous cholecystostomy followed by elective cholecystectomy after endoscopic treatment of any common bile duct stones diagnosed by percutaneous cholangiography. METHODS: From January 1989 to December 1998, 92 patients aged over 70 years were treated for acute gallstone cholecystitis. A group of 84 patients with ultrasonographic signs of severe cholecystitis or an American Society of Anesthesiologists score of II to IV were submitted to ultrasonographically guided percutaneous cholecystostomy. Transcatheter cholangiography was performed in all patients and endoscopic sphincterotomy was performed before operation in patients with common bile duct stones. After resolution of the acute phase and treatment of any associated diseases, patients were submitted to cholecystectomy. RESULTS: Cholecystostomy was performed successfully in 83 patients and permitted resolution of the acute attack in all after a mean period of 1.8 days. Cholangiography yielded a diagnosis of non-gallstone obstruction in one patient and common bile duct stones in 19 patients; preoperative endoscopic sphincterotomy and stone extraction was performed in 18 patients. Elective cholecystectomy was then performed in 70 patients with no deaths and a morbidity rate of 24 per cent. CONCLUSION: Combining emergency ultrasonographically guided percutaneous cholecystostomy, preoperative endoscopic treatment of common bile duct stones and subsequent elective cholecystectomy constitutes an optimal treatment regimen for acute gallstone cholecystitis in selected elderly patients with a mortality rate of zero in the authors' experience.
