In the present work, ZnO nanoparticles (NPs) were prepared using hydrothermal method with Trimethyl Ammonium Bromide (CTAB) as surfactant in 1- (hydroxyethyl)-3-methylimidazolium sulfate [EtOHMIM+] [HSO4 -] ionic liquid (IL). ZnO / PANI nanocomposite was prepared via in situ polymerization. The structures of the modified ZnO particles were characterized by X-ray diffraction, Raman spectroscopy and, scanning electron microscopy (SEM). The optical properties of (ZnO / PANI) nanocomposite were examined by photoluminescence (PL) analysis. XRD and, Raman analysis confirmed that pure ZnO (NPs) synthesized with (CTAB) in [EtOHMIM+] [HSO4 -] IL were formed. The addition of (CTAB) and [EtOHMIM+] [HSO4 -] IL does not change the ZnO phase but reduces the particle size of ZnO and converts shallow defects to deep defects. The SEM images of the ZnO / PANI nanocomposite showed the formation of hexagonal wurtzite ZnO (NPs) embedded in polyaniline matrix. The PL intensity of the ZnO / PANI nanocomposite is improved as compared to pure ZnO (NPs). This indicates that [EtOHMIM+] [HSO4 -] IL may be acting as a dye, since it is constituted by an organic part, [EtOHMIM+]. This good performance indicates that the synthesised nanocompsite is promising material as photoanode in solar cells. [ABSTRACT FROM AUTHOR]

Composite gel electrolytes of poly(IL)/IL/TiO2 containing poly [1-(hydroxyethyl)-3-vinylimidazolium hydrogen sulfate] (poly [EtOHVIM.][HSO4.]) as Poly(IL), 1-butyl-3-methyl-imidazolium hexafluorophosphate ([BMIM] PF6) as IL and Titanium Dioxide (TiO2) are prepared for dye-sensitized solar cells (DSSCs), without any volatile organic solvent. The performance of most (DSSCs) based on TiO2 was limited by the low electron mobility within TiO2. To produce a much higher power conversion efficiency performance and better long-term stability of the composite electrolyte without TiO2, a proper amount of TiO2 was added. Overall power conversion efficiency of 7.46% under simulated AM 1.5 solar spectrum irradiation for (DSSCs) based on the composite electrolytes were showed. This type of composite electrolytes had long-term stability of the (DSSCs), could overcome the drawbacks of volatile liquid electrolytes, and offer a feasible method to fabricate (DSSCs) in future practical applications.

Introduction: Jejunogastric intussusception (JGI) is a rare but potentially lethal complication following gastrectomy or gastrojejunostomy surgeries. Diagnosis of this condition can be challenging due to its rarity and non-specific symptoms. This article presents a case report of a 60-year-old male with a history of trans mesocolic gastrojejunostomy who developed acute symptoms of JGI., Case Report: The patient presented with acute epigastric pain, vomiting, and hematemesis. Physical examination and laboratory tests indicated dehydration, tachycardia, and leukocytosis. Computed tomography (CT) revealed intussuscepted loops within the stomach. Emergency laparotomy was performed, and the intussusception was manually reduced without the need for resection. The patient recovered well and was discharged five days post-surgery., Discussion: Retrograde jejunogastric intussusception is a rare complication, often occurring years after gastric surgery. It can be classified into acute and chronic forms, with the former presenting with intense pain and potential hematemesis. The condition can arise in different surgical contexts and even spontaneously. The cause of JGI remains unclear, but factors such as hyperacidity, abnormal motility, and increased intra-abdominal pressure have been implicated. Diagnosis can be made through endoscopy or alternative imaging modalities such as CT. Surgical intervention is the treatment of choice, with various options available based on intraoperative findings., Conclusion: Retrograde jejunogastric intussusception is challenging to diagnose and treat due to its rarity and lack of understanding of its causes. Imaging techniques and endoscopy play important roles in diagnosis, while surgery remains the primary treatment option. Vigilance is necessary among medical professionals to consider JGI in cases of acute abdominal pain and vomiting following gastric surgery, allowing for prompt diagnosis and intervention to prevent bowel necrosis. Further research is needed to establish optimal surgical strategies and evaluate recurrence rates., (© 2024. The Author(s).)

Introduction: Dieulafoy's lesion, a rare but life-threatening condition accounting for a small percentage of acute gastrointestinal bleeding cases, has historically posed diagnostic and therapeutic challenges., Case Presentation: In this article, we present two cases that required surgical intervention due to unsuccessful attempts with endoscopy. Case 1 involved a 40-year-old patient with a history of treated duodenal ulcers, while Case 2 featured a 74-year-old woman with no notable medical history. Both patients exhibited severe bleeding, necessitating urgent surgical procedures. The surgical approach involved wide gastrotomy, careful inspection, and successful suturing of the bleeding vessel., Discussion: Dieulafoy lesions, discovered by French surgeon Georges Dieulafoy in 1885, constitute 1-2 % of acute gastrointestinal bleeding cases. These anomalies involve enlarged submucosal arteries, predominantly in the stomach, but occurrences in other sites are documented. Endoscopic methods, surpassing surgical intervention, are preferred for treatment, boasting success rates over 90 %. Surgical measures become a last resort for uncontrolled bleeding, with laparoscopic surgery emerging as a minimally invasive alternative, facilitated by various intra-operative localization techniques. Laparoscopic wedge resection, in particular, exhibits lower re-bleeding rates than traditional oversewing methods, although feasibility depends on lesion location., Conclusion: While endoscopic methods are preferred, surgery remains a vital option when bleeding persists or endoscopic intervention fails. This report highlights the significance of surgical management in selected cases of Dieulafoy's lesion., Competing Interests: Declaration of competing interest All authors declare that they have no conflicts of interest., (Copyright © 2023 The Authors.

Introduction: Gallstone spillage during cholecystectomy is a recognized complication that can lead to various postoperative complications., Case Presentation: We present a rare case of a gallstone abscess that developed 20 years after an open cholecystectomy. An 80-year-old woman with a history of high blood pressure and previous gallbladder removal presented with severe abdominal pain. Imaging revealed a large abscess with a suspicious calcification, indicating a lost gallstone. Surgical intervention was performed, resulting in the removal of multiple gallstone fragments from the abscess cavity., Clinical Discussion: Gallbladder perforations and the spillage of gallstones are common complications during cholecystectomies, with laparoscopic procedures being more prone to stone spillage. Studies show a significant difference between open and laparoscopic cholecystectomies, with laparoscopy having a higher risk of spilled stones. Complications from spilled gallstones are rare but can vary in presentation and location. They may lead to long-term issues such as abscesses and even erosion into other organs. These complications can manifest years after surgery. Treatment involves evacuating the abscess and addressing the gallstone. Surgical intervention, like laparotomy or laparoscopy, is required for retrieval. Ensuring proper traction during surgery is crucial to prevent gallbladder perforation and stone spillage. Consideration of alternative, gentler instruments for traction may be beneficial., Conclusion: Surgeons should be vigilant, proactive, and employ prophylactic measures to minimize complications related to gallstone spillage, ensuring the best possible patient outcomes., Competing Interests: Conflict of interest statement All authors declare that they have no conflicts of interest., (Copyright © 2023 The Author(s).

Introduction and Importance: A common mesentery is defined by the persistence of an embryonic anatomical arrangement secondary to an anomaly of rotation of the primary umbilical loop. Caecal volvulus is a rare cause of intestinal obstruction, which account for 1 to 1.5 % of all intestinal obstructions. A combination of both, intestinal mal rotation and caecal volvulus is rare., Case Presentation: We report this rare entity in a 50 year old male with no history of abdominal surgery who was admitted for an acute intestinal obstruction. Clinical examination found a non-complicated right inguinal hernia. Radiological assessment showed signs of an incomplete common mesentery and an important small bowl distention with a transitional zone near the profound inguinal ring. Emergency surgery was performed. Surgical exploration didn't find signs of strangulation in the inguinal hernia which motivated midline laparotomy. We discovered a caecal volvulus with an incomplete common mesentery and ischemic lesions in the caecum. Ileocaecal resection was performed with ileocolostomy., Discussion: Common mesentery can be complete or incomplete. It is often well tolerated in adulthood. This intestinal malrotation can sometimes cause serious complications such as volvulus. Their association is rare. Radiology can be very helpful in leading to the diagnosis, but the diagnostic process should not delay surgical intervention which is the basis of the treatment., Conclusion: Caecal volvulus is a serious complication of intestinal malrotation. This association is rare in adulthood and symptoms are not specific. Emergency surgery is necessary., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to declare., (Copyright © 2023 The Authors.

Introduction and Importance: Bleeding from ileal varices is a rare and a life-threatening situation. Its management is difficult and includes endoscopic, surgical and interventional radiology treatment. Here we report a successful emergency surgery for bleeding ileal varices in a patient with cirrhosis due to autoimmune hepatitis., Presentation of a Case: A 60-year-old woman was admitted for rectal bleeding. She had a history of autoimmune hepatitis. She was treated by endoscopic ligation for oesophageal varices. Eso-gastro-duodenal fibroscopy and colonoscopy failed to reveal the bleeding site. CT scan was then performed showing ileal varices due to a portocaval shunt, there was a communication between the superior mesenteric vein and the right internal iliac vein. As the embolization was not feasible and the bleeding did not stop, an exploratory laparotomy was performed showing two dilated veins on the surface of the ileal wall, communicating with the right internal iliac vein. We performed a ligation of the vessels. Postoperative course was uneventful., Discussion: Ectopic varices are a rare case of gastrointestinal bleeding. Most of those patients have portal hypertension and liver cirrhosis. Diagnosing bleeding ileal varices is difficult because endoscopic examination can't always reveal the bleeding site. Interventional radiology is a good option for patients having bleeding ileal varices knowing that they often have advanced liver cirrhosis making them poor candidates for surgery. Haemostasis by endoscopy is often temporary and bleeding frequently recurs. Surgery should be considered if non-invasive treatments failed to ensure the haemostasis., Conclusion: Bleeding ileal varices is a rare situation. Interventional radiology and endoscopy can be good options. If not feasible, surgical treatment should not be delayed., (Copyright © 2021. Published by Elsevier Ltd.)

Tuberculous (TB) disease remains an endemic pathology in Tunisia. the ileocecal region is the predominant site of involvement while gastroduodenal tuberculosis is very rare, this form is often presenting as one of the complications, mainly upper gastrointestinal stenosis or exceptionally as a perforation. We describe a case of female patient aged 33 years-old presented with a 2-day history of acute abdominal pain, with a tenderness of the right hypochondrium and the epigastrium, ultrasound of the abdomen revealed gallbladder distension with a wall thickening. The diagnosis of acute cholecystitis was suspected and the patient had an exploratory laparoscopy that revealed the presence of a perforated duodenal ulcer which was blocked by the gallbladder and several peri-duodenal lymph nodes. Cholecystectomy was performed and the edges of the ulcer were resected and the ulcer was sutured. Histological examination revealed duodenal tuberculosis and the patient was referred to the TB eradication program., Competing Interests: All authors declare that they have no any conflicts of interest., (© 2021 Published by Elsevier Ltd on behalf of IJS Publishing Group Ltd.)

Introduction: and importance: Caecal volvulus represents 30% of colonic volvulus. It happens due to torsion or hyperflexion of a hypermobile caecum. Usually it is secondary to an axial rotation of the caecum and the ileum around the mesentery. On the other hand Intestinal malrotation occurs due to incomplete or faulty rotation and fixation of the gut during fetal life. The occurrence of these two anomalies together is scarse which makes this case report interesting., Case Presentation: A 75 year old man with medical history of terminal kidney failure, presented to the emergency room with an intestinal obstruction syndrome. On examination the patient had a distended abdomen with tenderness in the left upper quadrant. Biology found an important biological inflammatory syndrome with hyperleukocytosis and elevated CRP. Plain X-ray of the abdomen in erect posture showed an air fluid colonic level in the left hypochondrium. CT scan showed signs of caecal volvulus with intestinal malrotation. A brief reanimation and nasogastric aspiration couldn't solve the problem therefore emergency laparotomy was needed ileocaecal resection was performed associated with LADD's procedure in order to treat both anomalies and prevent further gut volvulus., Clinical Discussion: Despite it's rareness, caecul volvulus represents the second cause of large bowel volvulus just behind sigmoid volvulus. Intestinal malrotation in adults subjects is estimated to occur in 0.2-0.5%.The uniqueness of our case is that these two anomalies were associated in such a way that it made both the diagnosis and the therapy even more difficult. Abdominal CT has become mandatory for pre-operative diagnosis of intestinal volvulus. Surgery is the gold standard treatment for caecal volvulus. The usual options are manual detorsion, carcopexy, caecostomy and colectomy., Conclusion: This case reports a rare association of a caecum volvulus with intestinal malrotation that emphasis the place of modern technologies such as CT scan in order to achieve correct preoperative diagnosis. We also describe our approach to this uncommon surgical emergency in order to provide an efficient treatement., (© 2021 Published by Elsevier Ltd on behalf of IJS Publishing Group Ltd.)

Pancreatic metastasis (PM) of renal cancer is a rare condition. It is characterized by a long period after initial nephrectomy and a favorable prognosis compared to other pancreatic malignancies. Its diagnosis may confuse clinicians if the medical history is not known. In the era of targeted therapies for metastatic renal carcinoma, surgery stands as the best treatment option for PM of renal cancer. We report the case of a woman who underwent successfully left splenopancreatectomy for corporeal PM of renal cancer treated seven years ago. This case underlines the necessity of long-term follow-up of patients treated for kidney cancer., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2021 Feryel Letaief Ksontini et al.)

Introduction and Importance: Crohn's disease is a chronic inflammatory bowel disease with complex pathophysiology and multiple complications, some of which can be fatal. We report herein the management of an unusual case of Crohn's disease revealed by two life-threatening complications., Case Presentation: A 59-year-old patient presented with an acute abdominal pain evolving for one day with a clinical presentation in favor of peritonitis by perforation of the last ileal loop and acute limb ischemia. At emergency laparotomy, we found a fecal peritonitis by perforation of the last ileal loop. The patient underwent an ileo-caecal resection with rifle barrel ileo-colostomy associated with embolectomy using a Fogarty catheter of the femoral artery. Pathological examination of the specimen showed an aspect consistent with an ileo-caecal Crohn's disease and blood clot embolus of the femoral artery. Postoperative course was uneventful and the patient was kept in remission with immunosuppressants., Discussion: Several complications may arise during the evolution of the disease. However, Life-threatening complication scarcely inaugurate crohn's disease like in our patient. Free perforation of the small intestine in crohn's disease occurs rarely, which makes its statistical study difficult. Risk factors for perforation are still poorly identified. Patients diagnosed with crohn's disease have a higher risk of thromboembolic complications. Indeed, there is an association between the activity of the disease and thromboembolic events. In our case, the severity of the clinical presentation as well as its inaugural character are unique., Conclusion: The management of inaugural two uncommon acute conditions in Crohn's disease is challenging., (Copyright © 2021 The Authors.

Introduction: Hydatid disease is a global zoonosis. Any organ of the human body can be involved. Single or multiple locations are reported. However, retroperitoneal hydatid cysts are uncommon. Furthermore, parietal complications are rarely reported in literature. Therefore, the management of hydatid cysts ruptured in the abdominal wall remains challenging., Presentation of Case: In this case report, we aim to describe our experience in treating a primary retroperitoneal hydatid cyst with rupture into abdominal wall in an 87-year-old woman who presented with a 15-centimeter mass of the right flank. Hydatid serology test was positive. An abdominal CT scan showed a 20-centimeter cystic mass of retroperitoneum extended to the abdominal wall with several septa within and enhanced thick wall. The patient underwent a surgical elective drainage with perioperative antiparasitic chemotherapy. Follow-up showed no recurrence., Discussion: Primary retroperitoneal hydatid cyst with parietal complications is scarce and barely described in literature. We performed a review of the recent relevant literature that deals with this subject. None of the hydatid cysts reported in 55 cases was located in retroperitoneum. The top seven countries of origin are located in Mediterranean region except for India. Imaging is compulsory for the diagnosis along with patient's history, physical examination and hydatid serology. The treatment is surgical and must be must be covered by antiparasitic chemotherapy., Conclusion: Primary retroperitoneal hydatid cyst extended to the abdominal wall remains a rare and challenging diagnosis that must be considered in endemic countries., (Copyright © 2020 The Authors.

Several recent studies of hydroxyl-functionalized ionic liquids (ILs) have shown that cation-cation interactions can be dominating these materials at the molecular level when the anion involved is weakly interacting. The hydrogen bonds between the like ions led to the formation of interesting chain-like, ring-like, or distinct dimeric (i. e. two ion pairs) supermolecular clusters. In the present work, vibrational spectroscopy (ATR-IR and Raman) and density functional theory (DFT) calculations of the hydroxyl-functionalized imidazolium ionic liquid C 2 OHmimCl indicate that anion-cation hydrogen bonding interactions are dominating, leading to the formation of distinct dimeric ion pair clusters. In this arrangement, the Cl - anions function as a bridge between the cations by establishing bifurcated hydrogen bonds with the OH group of one cation and the C(2)-H of another cation. Cation-cation interactions, on the other hand, do not play a significant role in the observed clusters., (© 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.)

Background: The ideal way to show treatment effectiveness is through randomized controlled trials the 'gold standard' in evidence-based surgery. Indeed, not all surgical studies can be designed as randomized trials, sometimes for ethical and otherwise, for practical reasons. This article aimed to compare laparoscopic cholecystectomy to open cholecystectomy, according to data from an administrative database, managed by a propensity matched analysis., Methods: Were included all patients with cholelithiasis admitted in Department B between June 1st, 2008 and December 31st, 2009. In this study, the propensity score represented the probability that a patient would be treated by a procedure based on variables that were known or suspected to influence group assignment and was developed using multivariable logistic regression used here to match patients who had laparoscopic cholecystectomy to a control patient who had open cholecystectomy. The main outcome measure was morbidity. This was expressed as the number of patients with 1 or more complications occurring during the hospital stay or within 30 days following discharge., Results: According to intention to treat, 535 patients had a laparoscopic approach (LC group) and 60 patients had a traditional open approach (OC group) regarding associated cardiac disease, previous laparotomy or when choledocholithiasis was suspected, however intra operative cholangiography showed that there was no choledocolithiasis. According to the propensity score, 28 patients in OC were matched with 58 in LC. Comparison between OC and LC before and after propensity matched analysis showed that OC was associated with a higher rate of Extra Surgical Site morbidity (p= 0.010), a longer median duration of intervention, post-operative stay and overall hospital stay (p= 0. 0001)., Conclusion: LC should be considered as first-line therapy to treat cholelithiasis surgically even if it becomes necessary to convert to OC because of intra operative findings.

Background: Gastrointestinal stromal tumors (GIST) are the most common digestive sarcomas. They develop in most cases in the stomach and small intestine, more rarely rectum, colon, esophagus or mesentery. These tumors typically express the phenotype CD117/KIT + and CD34 +., Aim: To evaluate epidemiologic, clinical, pathologic, therapeutic, characteristics and evaluative pattern of gastrointestinal tumor treated in our surgical department., Patients and Methods: We collected 24 cases of GIST (confirmed by the positivity of CD 117 and/or CD 33) treated between 1997 and 2010 in the department of surgery B of Charles Nicolle's Hospital. We analyzed demographic characteristics, clinic pattern, investigations treatment and therapeutic variables of our patients. We calculated the survival rate and identified prognostic predictive factors of survival., Results: Our retrospective study interested, during 13 years, 24 patients presenting GIST with a median age of 66 years and a sex ratio of 0.8. The median time for diagnosis was two months (3 days to 24 months). Abdominal pain, gastrointestinal bleeding and vomiting were the most common symptoms. The endoscopic appearance was tumor arising from muscular layer found in the stomach (13/24 cases; 54%), small bowel in four cases (16.5%) and duodenal or rectum three patients (12,5 %). Twenty three within 24 patients underwent surgical resection with R0 in 20/23 cases. Three patients were treated with neoadjuvant imatinib for an average of 12 months, one patient had adjuvant treatment and four patients in locoregional evolutive tumor and / or metastatic. The overall survival was 70% at one year and 65% at two years with a pejorative impact, in univariate analysis of abdominal pain, asthenia, anorexia, weight loss, cytonuclear atypia, tumor size ≥ 10 cm and a mitotic index ≥ 5/50. Multivariate analysis showed that tumor size (Hazard Ratio = 6 if size ≥ 10 cm 95% CI [1,539-24,017]) and weight loss (Hazard Ratio = 7 95% CI [1,664-29,100]) were influential factors on overall survival and recurrence-free survival., Conclusion: The prognostic predictive factors identified were the size of tumor ≥ 10cm and the mitotic index.

Background: Administrative database, used previously for control of cost, patient flow and invoicing, offer to researchers a large sample of patients representative of population providing interesting information's in the field of descriptive and analytic epidemiology with less cost., Aim: To compare spinal to general anesthesia for inguinal hernia repair concerning a population extracted from administrative database after propensity matched analysis., Methods: Prospective study concerning 4690 hospitalizations in Department B of General Surgery of Charles Nicolle hospital during a period of 18 months, between June 1st, 2008 and December 31st, 2009. A descriptive analysis followed by a comparison between spinal and general anesthesia according propensity matched analysis were performed. Résultats: 595 inguinal hernias were operated on. Mean age was 55±15.We mentioned a male predominance: 326 men (84.2%) and 61 women (15.8%). 137 patients had previous medical diseases(35.4%). 47(12.1%) patients were operated on in emergent situation on the other hand 340(87.9%) had elective surgery.264(68.2%) were ASA I, 110(28.4%) ASA II, 13(3.4%) ASA III. Post operative course were uneventful in 96.1% (372) and complicated in 11 patients (2.9%).Four deaths were observed (1%). Comparison before and after propensity matched analysis showed a statistical difference regarding postoperative stay and all hospital stay in favor of spinal anesthesia (p=0.007)., Conclusion: Postoperative stay is significantly shorter in the group of spinal anesthesia (p=0.007). A randomized clinical trial comparing spinal anesthesia to general anesthesia is needed.

Background: Administrative database, used previously for control of cost, patient flow and invoicing, offer to researchers a large sample of patients representative of population providing interesting informations in the field of descriptive and analytic epidemiology with less cost., Aim: To assess the usefulness of administrative database for quality of care and research., Methods: It was a prospective study concerning 4690 hospitalisations in Department B of General Surgery of hôpital Charles Nicolle during a period of 18 months, between June 1st, 2008 and December 31st, 2009. A descriptive analysis followed by a pronostic study with a univariate and multivariate analysis was performed. RÉSULTATS : Our study showed the usefulness of an administrative database in assessing the quality of care, it allowed us to determine postoperative mortality rate (2.7%), deep morbidity (2.5%), parietal morbidity (1.2%), medical complications (6%), nosocomial infections (3.6%) and re intervention (2.7%), with independent predictive factors of these events. To reduce the incidence of these events we should reduce length of pre-operative stay, prevent intra operative accidents, avoid intra operative bleeding in order to reduce intra operative transfusions and avoid as far as possible the stay in ICU Independent predictors of post trauma death are multiple trauma [OR: 6.14, 95% (from 1.68 to 16.94), p = 0.002], a traumatized patient in distress on arrival [OR: 8.74, 95% (3.59 -27.77), p = 0.000] and overall medical complications [OR: 13.18, 95% (from 4.01 to 31.25), p=0.000]. The ISS is a good discriminative indice to assess the severity and life-threatening risk., Conclusion: Administrative databases provide information on the efficiency of care, it helps to realise observational studies on large samples representative of the population at low cost. They are very useful in the research, despite the lack of clinical data.

Enterosalpingeal fistula is a rare complication of Crohn's disease which is rarely diagnosed preoperatively. We describe a new case of this complication suspected by CT scan and confirmed by hysterosalpingogram and contrast from the ileum. This case is about a 50-year-old woman suffering from ileal Crohn's disease diagnosed two years previously and actually complicated by stenosis and entero-salpingeal fistula. The treatment consisted on resection of the ileocaecal region with salpingectomy. Postoperative course was uneventful.
