LAPAROSCOPIC APPENDICECTOMY: RISK FACTORS FOR CONVERSION TO LAPAROTOMY.

BACKGROUND: Laparoscopic appendectomy is the gold standard surgical procedure currently performed for acute appendicitis. The conversion rate is one of the main factors used to measure laparoscopic competence, being important to avoid wasting time in a laparoscopic procedure and proceed directly to open surgery. AIMS: To identify the main preoperative parameters associated with a higher risk of conversion in order to determine the surgical method indicated for each patient. METHODS: Retrospective study of patients admitted with acute appendicitis who underwent laparoscopic appendectomy. A total of 725 patients were included, of which 121 (16.7%) were converted to laparotomy. RESULTS: The significant factors that predicted conversion, identified by univariate and multivariate analysis, were: the presence of comorbidities (OR 3.1; 95%CI; p<0.029), appendicular perforation (OR 5.1; 95%CI; p<0.003), retrocecal appendix (OR 5.0; 95%CI; p<0.004), gangrenous appendix, presence of appendicular abscess (OR 3.6; 95%CI; p<0.023) and the presence of difficult dissection (OR 9.2; 95%CI; p<0.008). CONCLUSIONS: Laparoscopic appendectomy is a safe procedure to treat acute appendicitis. It is a minimally invasive surgery and has many advantages. Preoperatively, it is possible to identify predictive factors for conversion to laparotomy, and the ability to identify these reasons can aid surgeons in selecting patients who would benefit from a primary open appendectomy.

RESUMO RACIONAL: A apendicectomia laparoscópica é o procedimento cirúrgico padrão-ouro realizado atualmente para apendicite aguda. A taxa de conversão é um dos principais fatores utilizados para medir a competência laparoscópica, e importante para evitar perda de tempo em um procedimento laparoscópico e proceder diretamente à cirurgia aberta. OBJETIVO: Identificar os principais parâmetros pré-operatórios associados ao maior risco de conversão para determinar o método cirúrgico indicado para cada paciente. MÉTODOS: Estudo retrospectivo de pacientes admitidos com apendicite aguda, submetidos a apendicectomia laparoscópica. Foram incluídos 725 pacientes, sendo que destes, 121 (16,7%) foram convertidos para laparotomia. RESULTADOS: Os fatores significativos que predizem a conversão, identificados por análise univariada e multivariada, foram: presença de comorbidades (OR 3,1; IC95%; p<0,029), perfuração apendicular (OR 5,1; IC95%; p<0,003), apêndice retrocecal (OR 5,0; IC95%; p<0,004), apêndice gangrenoso, presença de abscesso apendicular (OR 3,6; IC95%; p<0,023) e a presença de dissecção difícil (OR 9,2; IC95%; p<0,008). CONCLUSÕES: A apendicectomia laparoscópica é um procedimento seguro para tratar apendicite aguda. É uma cirurgia minimamente invasiva e tem muitas vantagens. No pré-operatório, é possível identificar os fatores preditores de conversão para laparotomia, e a capacidade de identificar essas razões pode ajudar os cirurgiões na seleção de pacientes que se beneficiariam de uma apendicectomia aberta primária.

Ambulatory hernia repair: a study of 1294 patients in a single institution.

Introduction: ambulatory surgery is continuously expanding in global reach because of its several advantages. This study aimed to describe the experience of our department in outpatient hernia surgery, evaluate its feasibility and safety, and determine the predictive factors for failure of this surgery. Methods: we conducted a monocentric retrospective cohort study on patients who had ambulatory groin hernia repair (GHR) and ventral hernia repair (VHR) in the general surgery department of the Habib Thameur Hospital in Tunis between January 1st, 2008 and December 31st, 2016. Clinicodemographic characteristics and outcomes were compared between the successful discharge and discharge failure groups. A p-value of ≤ 0.05 was considered significant. Results: we collected data from the record of 1294 patients. One thousand and twenty patients had groin hernia repair (GHR). The failure rate of ambulatory management of GHR was 3.7%: 31 patients (3.0%) had unplanned admission (UA) and 7 patients (0.7%) had unplanned rehospitalization (UR). The morbidity rate was 2.4% while the mortality rate was 0%. On multivariate analysis, we did not identify any independent predictor of discharge failure in the GHR group. Two hundred and seventy-four patients underwent ventral hernia repair (VHR). The failure rate of ambulatory management of VHR was 5.5%: 11 patients (4.0%) had UA and 4 patients (1.5%) had UR. The morbidity rate was 3.6% and the mortality rate was zero. On multivariate analysis, we did not identify any variable predicting discharge failure. Conclusion: our study data suggest that ambulatory hernia surgery is feasible and safe in well-selected patients. The development of this practice would allow for better management of eligible patients and would offer many economic and organizational advantages to healthcare structures.

Surgical management of splenic artery aneurysm.

INTRODUCTION: Splenic artery aneurysms are a rare arterial disease. They are considered as the most common visceral artery aneurysms and found mostly in multiparous women and patients with portal hypertension. CASE PRESENTATION: We present a case of an unruptured SAA of the hilum in a 58-year-old woman, with vague abdominal pain, treated by open splenectomy. DISCUSSION: Splenic artery aneurysms are often difficult to diagnose due to their vague or asymptomatic forms. However, they present a high risk of rupture that may cause fatal hemorrhage and death. Symptomatic artery aneurysms or SAA, larger than 20 mm and aneurysms in pregnant or in women of childbearing age are indications for surgery because of the increased risk of rupture in these patients' groups. As known generally, the treatment of SAA has been surgical ligation of the splenic artery, ligation of the aneurysm or aneurysmectomy with or without splenectomy, depending on the aneurysm location. There are other percutaneous interventional procedures. CONCLUSION: A multidisciplinary discussion is an important step in choosing the optimal treatment for visceral aneurysms. Surgical approaches should take place especially in cases where splenic perfusion is seriously threatened.

Gastric EBV-positive mucocutaneous ulcer: A rare pathological entity.

The gastric location of EBVMCU is extremely rare. The pathology examination and immunochemistry are mandatory for the diagnosis. It is essential that physicians be aware of this new entity to accurately diagnose and handle this disease.
