RESUMO
BACKGROUND: Signet-ring cell carcinoma of the stomach (SRCC) is a particular gastric cancer entity. Its incidence is increasing. Its diagnosis is pathological; it corresponds to adenocarcinoma with a majority of signet-ring cells component (> 50%). These histological features give it its aggressiveness characteristics. This has repercussions on the prognostic level and implications for the alternatives of therapy, especially since some authors suggest a potential chemoresistance. This survey aimed to identify the epidemiological, pathological, therapeutic, and prognostic characteristics of SRCC as a separate disease entity. METHODS: This was a retrospective study of 123 patients admitted for gastric adenocarcinoma to Habib Thameur Hospital in Tunis over 11 years from January 2006 to December 2016. A comparative study was performed between 2 groups: the SRCC group with 62 patients and the non-SRCC (non-signet-ring cell carcinoma of the stomach) with 61 patients. RESULTS: The prevalence of SRCC in our series was 50%. SRCC affected significantly younger patients (55 vs 62 years; p = 0.004). The infiltrative character was more common in SRCC tumors (30.6 vs 14.8%; p = 0.060), whereas the budding character was more often noted in non-SRCC tumors (78.7 vs 58.1%; p = 0.039). There was no significant difference in tumor localization between both groups. Linitis plastica was noted in 14 patients with SRCC against a single patient with non-SRCC (p = 0.001). The tumor size was more important in the non-SRCC group (6.84 vs 6.39 cm; p = 0.551). Peritoneal carcinomatosis was noted in 4.3% of cases in the SRCC group versus 2.2% of cases in the NSRCC group (p = 0.570). Total gastrectomy was more often performed in the SRCC group (87 vs 56%; p = 0.001). Resection was more often curative in the non-SRCC group (84.4 vs 78.3%; p = 0.063). Postoperative chemotherapy was more commonly indicated in the SRCC group (67.4 vs 53.3%; p = 0.339). Tumor recurrence was more common in the non-SRCC group (35.7 vs 32%; p = 0.776). The most common type of recurrence was peritoneal carcinomatosis in the SRCC group (62.5%) and hepatic metastasis in the non-SRCC group (60%; p = 0.096). The overall 5-year survival in the SRCC group was lower than in the non-SRCC group, with no statistically significant difference (47.1 vs 51.5%; p = 0.715). The overall survival was more important for SRCC in early cancer (100 vs 80%; p = 0.408), whereas it was higher for non-SRCC in advanced cancer (48.1 vs 41.9%; p = 0.635). CONCLUSION: Apart from its epidemiological and pathological features, SRCC seems to have a worse prognosis. Indeed, it is diagnosed at a more advanced stage and has a worse prognosis in advanced cancer than non-SRCC. It is therefore to be considered as a particular entity of gastric adenocarcinoma requiring a specific therapeutic protocol where the place of chemotherapy remains to be more investigated.

INTRODUCTION AND IMPORTANCE: Locally advanced jejunal stromal tumors stand as a captivating and relatively rare entity, garnering attention for several reasons. Their inaccessible location by conventional endoscopy poses a diagnostic challenge. Further, treatment decisions necessitate a multidisciplinary approach, compounded by the absence of high-level evidence studies. CASE PRESENTATION: A 54-year-old patient was admitted to our surgical department with abdominal pain and chronic anemia. Abdominal CT imaging confirmed the presence of a non-metastatic sizable jejunal tumor. The patient underwent laparotomy, revealing a locally advanced jejunal tumor contracting the ileum and the ascending colon. A monobloc oncological resection was performed, followed by the restoration of digestive continuity. Anatomopathological analysis delineated a locally advanced Stromal Tumor with a high risk of recurrence. The patient underwent a course of tyrosine kinase inhibitors for 3 years, with no reported recurrence during the subsequent 3-year follow-up. DISCUSSION: Locally advanced jejunal stromal tumors are rare. Most patients present with unspecific symptoms. Diagnosis remains challenging due to their intricate anatomical location. Decisions regarding management must be deliberated within a multidisciplinary framework, tailored to each patient's unique characteristics. While combined therapeutic modalities have demonstrated efficacy in recent studies, prudence is advised given the heightened incidence of both short and long-term complications. CONCLUSION: In the absence of randomized controlled trials, the management of locally advanced jejunal stromal tumors underscores the imperative of multidisciplinary collaboration in treatment deliberations. A wide, sometimes mutilating excision is only permissible if it is complete.
RESUMO
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 signiï¬cant 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 beneï¬t from a primary open appendectomy.

BACKGROUND: Occlusion is the most common complication of colon cancer. Surgical treatment is associated with the highest morbidity and mortality rate (10-27%) and has the worst prognosis. It is necessary for immediate management, avoiding colic perforation and peritonitis. The increase in mortality in emergency colon cancer surgery is multifactorial. AIMS: The aim of this study was to identify the risk factors for early postoperative mortality that highlights the therapeutic strategy in the management of obstructive colon cancer. METHODS: A retrospective study was performed on patients admitted from 2008 to 2020 at the Department of General Surgery due to obstructive colon cancer and operated on as an emergency (within 24 h of admission). RESULTS: In all, 118 patients with colon cancer were operated, and the early postoperative mortality was 10.2%. The univariate analysis highlighted that the American Society of Anesthesiology score III or IV, perforation tumor, one postoperative complication, and two simultaneous postoperative complications were considered significant risk factors for early postoperative mortality after emergent surgery. Multivariate analysis showed that only tumor perforation and the occurrence of two postoperative complications were significant risk factors. CONCLUSION: This study showed that postoperative complication is the leading cause of early postoperative mortality after emergency surgery for obstructive colon cancer. Optimizing the postoperative management of these higher risk patients is still necessary and may reduce the mortality rate.

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.

BACKGROUND: Erector spinae plane (ESP) block is a recently described interfacial block, and since 2016, studies have shown that it is a safe technique related to the lower risk of neurovascular and pleural injury comparing to epidural or paravertebral blockade. The application of ESP block in abdominal surgery is relatively limited to case reports and small population studies, which is why we believe every new case of its application should be a valuable contribution. CASE PRESENTATION: With this present case, we explored the efficacy of bilateral ESP block as a post-operative analgesia technique for liver hydatid surgery on a 56-year-old patient. Ultrasound-guided bilateral ESP block was applied at T7 level, while the patient was awake before general anaesthesia induction. The local anaesthetic used was 20 mL ropivacaine (0.375%) and 2 mg dexamethasone on each side. After recovery from anaesthesia, she reported mild pain (visual analogue score of 5 on effort). After 12 hours post-operatively, she received only one dose of paracetamol 1 g considered as rescue analgesic. She did not experience nausea and vomiting episodes. We noted a sensory block extending from T4 to T10. CONCLUSION: To our knowledge, it may be the first adult bilateral single-shot case report for this specific procedure. This technique appears to be safe and effective on post-operative analgesia for this type of surgery; however, prospective studies comparing ESP block to other techniques are needed.

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.
RESUMO
INTRODUCTION: Laparoscopic cholecystectomy is the gold standard treatment for symptomatic gallstones. There is some debate as to whether it should be performed in outpatient surgery or in one-day surgery to improve patient safety. This study aimed to evaluate the impact of laparoscopic cholecystectomy performed in outpatient surgery versus one-day surgery on standards such as mortality, serious adverse events and quality of life. METHODS: We conducted a cross-sectional descriptive study in the Department of General Surgery at the Habib Thameur Hospital over the period May 2009-February 2010. We here report 67 cases of symptomatic vesical lithiasis treated with outpatient laparoscopic cholecystectomy (OLC). ASA III and IV patients, diabetic patients treated with sulfonamides or insulin, severely obese patients, patients over 65 years of age and under 18 years of age, patients with a history of major abdominal surgery, patients with suspected lithiasis of the common bile duct, acute cholecystitis or pancreatitis were excluded from the study. Patients had to reside within 50 km of the hospital and be accompanied by an adult to undergo OLC. RESULTS: Seventeen patients were included and then excluded from our study because of the perioperative detection of signs of acute cholecystitis or difficulties in dissection leading to subhepatic drainage using Redon catheter at the end of the intervention. Finally, our study included 50 patients, 7 men and 43 women; the average age was 48 years. Surgery was based on the most common procedures. After leaving the recovery room, patients were conducted in the outpatient sector where they received a liquid diet. The patients were examined before 7 o'clock in the evening and discharge was established on the basis of the possibility of establishing an oral analgesic treatment, patients tolerance to liquid diet, the lack of urinary disorder, patients acceptance for discharge and analgesic and anti-inflammatory treatment if needed. Thirty-nine patients (78%) were discharged from hospital and 11 were kept in hospital. Patients > 45 years of age, anesthesia duration > 70 minutes and post operative fatigue were identified as risk factors for unsuccessful discharge. No readmission was observed. Discharged patients were satisfied with the therapeutic protocol, resulting in excellent and good outcome in the majority of cases (94%). CONCLUSION: Outpatient laparoscopic cholecystectomy seems to be as safe as day surgery laparoscopic cholecystectomy having low rate of complications and of hospital readmissions in some selected patients and lower surgery costs.

RESUMO RACIONAL: A oclusão é a complicação mais comum do câncer de cólon. A cirurgia está associada à elevada morbimortalidade (10-27%) e pior prognóstico. É necessário indicação imediata, evitando perfuração cólica e peritonite. O aumento da mortalidade na cirurgia de emergência do câncer de cólon é multifatorial. OBJETIVOS: Identificar os fatores de risco de mortalidade pós-operatória precoce que levaram a destacar a estratégia terapêutica no manejo do câncer de cólon obstrutivo. MÉTODOS: Estudo retrospectivo em pacientes admitidos no Departamento de Cirurgia Geral, entre 2008 e 2020, por câncer de cólon obstrutivo e operados de emergência (dentro de 24 horas da admissão). RESULTADOS: Foram operados 118 pacientes e a mortalidade pós-operatória precoce foi de 10,2%. A análise univariada destacou que escore American Society of Anesthesiology III ou IV, tumor perfurado, uma complicação pós-operatória e duas complicações pós-operatórias simultâneas foram considerados fatores de risco significativos de mortalidade pós-operatória precoce após cirurgia de emergência no câncer de cólon obstrutivo. Na análise multivariada, apenas a perfuração tumoral e a ocorrência de duas complicações médicas pós-operatórias foram fatores de risco significativos. CONCLUSÃO: Este estudo mostrou que a complicação pós-operatória é a principal causa de mortalidade pós-operatória precoce após cirurgia de emergência de câncer de cólon obstrutivo. Otimizar o manejo pós-operatório desses pacientes de alto risco ainda é necessário e pode reduzir a taxa de mortalidade.
