Laparoscopic management of intestinal obstruction in a young adult with a virgin abdomen: Unusual presentation of combined vitellointestinal duct remnants: A clinical case report.

Key Clinical Message: In an 18-year-old, Meckel's diverticulum and a rare vitellointestinal fibrous band caused bowel obstruction. Clinicians should be vigilant for such anomalies, especially in young adults with virgin abdomens, as potential sources of intestinal obstruction. Abstract: In this case report, we highlight the rarity of vitellointestinal or omphalomesenteric duct anomalies causing intestinal obstruction in the adult population. The patient, an 18-year-old male, presented to the emergency department with a two-day history of abdominal pain and vomiting. Physical examination revealed mild distension of his virgin abdomen with generalized tenderness. Abdominal X-ray displayed dilated small bowel loops, and a computed tomography scan indicated features consistent with closed-loop bowel obstruction. Diagnostic laparoscopy confirmed a vitellointestinal duct remnant as the cause of the small intestinal obstruction, involving a combined Meckel's diverticulum and vitellointestinal fibrous band. In early fetal development, the vitellointestinal duct communicates between the midgut and the yolk sac, expected to disappear during fetal growth. Failure to obliterate can lead to issues such as intestinal blockage, primarily observed in children, making occurrences in adults, as in this case, infrequent with only a few documented instances. Despite its uncommon occurrence in young adults, healthcare providers should consider the vitellointestinal duct anomalous remnant as a potential source of intestinal obstruction, particularly in individuals with a virgin abdomen. Early detection of intestinal obstruction is imperative for patient survival, facilitating prompt management and minimizing the risk of serious morbidities, ultimately contributing to a better patient outcome.

Adult appendicitis score versus Alvarado score: A comparative study in the diagnosis of acute appendicitis.

Background: Acute Appendicitis (AA) is the most common abdominal surgical emergency. It requires proper management to decrease mortality and morbidity. Clinical scoring systems for diagnosing AA aimed to decrease the use of radiological scans and the rate of negative appendectomies (NA). We aim to assess the adult appendicitis score (AAS) in the diagnosis prediction of AA. Method: A retrospective study with 1303 cases of AA is performed. We compared the correlation of AAS and Alvarado scores to postoperative histopathology. Specificity, sensitivity, Positive Predictive Value (PPV), and Negative Predictive Value (NPV) were assessed. ROC was used. Results: AAS risk stratification was applied to the study population. Group I for a low probability, and groups II and III for an intermediate and high probability of AA. We found that 159 patients were matched in group I, 505, and 639 were in groups II and III of AAS, respectively. The correlation between Alvarado and AAS with HP was significant. AAS ≥ 16 presented sensitivity and specificity of 50 % and 75.47 %, respectively, with PPV of 97.96 % and NPV of 6.02 %, with an accuracy of 51.04 %. Regarding AAS ≥ 11, the sensitivity was 88.96 %, specificity was 39.62 %, PPV was 97.2 %, NPV was 13.21 %, and accuracy was 86.95 %. Conclusion: AAS is relatively more accurate than Alvarado's score, especially in selecting a safe candidate for discharge from an emergency. In addition, AAS is found to decrease the need for radiological images and NA rate more than Alvarado.

The Role of Alvarado Score in Predicting Acute Appendicitis and Its Severity in Correlation to Histopathology: A Retrospective Study in a Qatar Population.

Background/objective Acute appendicitis (AA) is one of the most common surgical emergencies that require a proper diagnosis to avoid a negative outcome in the case of missed or delayed diagnosis. Our study aims to assess the diagnostic power of the Alvarado score and the prediction of the severity of acute appendicitis in correlation to intraoperative findings and the final histopathology (HP) result. Methods This retrospective study was applied to 1,303 patients with clinically proven acute appendicitis (AA) and available HP results. We correlated Alvarado score to the gold standard HP and intraoperative findings. We selected the cutoff point of Alvarado at 5 and 7 as they were the most frequent cutoff value mentioned in the literature and based on the ROC curve in this study to assess sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). Results The mean age of the study cohort is 33.3 ± 9.5 years, with a male predominance (75.8%). The negative appendectomy (NA) rate was 4%. The operative complication rate was 1.2%, and we recorded one mortality case (0.1%). The diagnostic evidence of AA was in 95.9% of cases. Alvarado score ≥ 7 presented sensitivity and specificity of 66.4% and 69.8%, respectively, with PPV of 98.1% and NPV of 8.1%, with an accuracy of 66.5%. For Alvarado score ≥ 5, the sensitivity was 91.2%, specificity was 22.6%, PPV was 96.5%, NPV was 9.8%, and accuracy was 88.4%. In addition, we demonstrated statistical significance between Alvarado risk stratification with HP and intraoperative grades (p = 0.001 each). Conclusion The Alvarado scoring system alone is not enough to diagnose AA with unsatisfactory sensitivity and specificity. However, it is a good indicator of the severity of AA that we can depend on to prioritize those patients waiting for surgery.

Successful Surgical Management of Unusual Gallbladder Anatomy Through Laparoscopic Cholecystectomy of Ectopic Gallbladder.

Abnormalities in the position of the gallbladder are not encountered commonly such as the ectopic location. We present a case of laparoscopic cholecystectomy for gallbladder that was found in an ectopic position. The surgical procedure can be difficult in some cases of acute cholecystitis and ectopic position of the gallbladder may add to complexities of the procedure due to abnormal location or anatomical variants of the biliary tree. Preoperative identification of ectopic gallbladder may aid in planning and performing a safe surgical procedure.

From Diagnosis to Management; Mucocele of Stump Appendicitis, Extremely Rare Finding in an Uncommon Surgical Disease: Literature Review.

Mucocele of the appendix is the accumulation of mucoid material in the appendiceal lumen. Although the terminology is imprecise, as it does not differentiate between the benign and malignant nature of the condition, preoperative recognition is imperative as spillage of the mucus during surgical handling can result in grave complications like pseudomyxoma peritonei. Mucocele developing in a stump of the appendix, i.e., a remnant of appendiceal tissue after surgical removal of an inflamed organ, is an extremely uncommon phenomenon, as not many cases are reported in the literature. In this review, all cases reported in English literature are discussed.

Appendicitis Secondary to Trauma following a Camel Kick: Case Report and Review of Literature.

INTRODUCTION: Independently, trauma and appendicitis are two of the most common conditions in surgical practice. Rarely, both conditions may coexist, which raises the controversy whether it is merely a coincidence or trauma may lead to acute appendicitis. Presentation of Case. We report a case of acute appendicitis after blunt abdominal trauma caused by a camel hoof kick to the abdomen in a young man and discuss the potential underlying pathophysiologic mechanisms with review of the pertinent literature. CONCLUSIONS: Blunt abdominal trauma caused by a camel kick to the abdomen requires a close observation of the patients. A camel kick may increase intra-abdominal pressure and cause internal organ injury including the appendix. Therefore, acute appendicitis should be considered in differential diagnosis in any patient with abdominal pain resembling appendicitis following blunt abdominal trauma.

Incidental low grade mucinous neoplasm of appendix in pregnancy: A case report & literature review.

INTRODUCTION: Mucinous neoplasms of appendix account for 0.2-0.4% of all the appendix specimens. The occurrence of this neoplasm in pregnancy is extremely rare. We describe a case of a pregnant lady who was diagnosed as acute appendicitis and found to have Low-Grade Mucinous neoplasm on histopathology. In the existent literature, there are only a few such cases reported and none from our Middle East region. CASE PRESENTATION: 42-year-old pregnant lady at 24 weeks of gestation presented with classical symptoms of acute appendicitis. She had leukocytosis but the Ultrasound was equivocal. She underwent laparoscopic appendectomy and found to have an inflamed appendix. Postoperative recovery was satisfactory and was discharged home. The histopathology report showed low-grade mucinous neoplasm of the appendix and she was detailed about it on follow up. DISCUSSION: The incidence of appendiceal neoplasm is rare in routine appendectomy and carcinoid is the most common tumor of the appendix. Low-Grade mucinous neoplasm is a rare entity and its presence in pregnancy is further rarer. CONCLUSION: Since this neoplasm does not manifest with a characteristic clinical profile it is difficult to diagnose, even with extensive preoperative evaluation. Although surgical treatment is straight forward, the management of the appendiceal neoplasm during pregnancy necessitates full knowledge of the natural history of the disease to attain equilibrium of concern for maternal survival and fetal health.

A Unique Case of Low-Grade Mucinous Neoplasm in Stump Appendectomy.

BACKGROUND: We describe a case of a young male with a history of appendectomy one year ago, who developed symptoms of stump appendicitis, and after removing this stump, histopathology showed low grade neoplasm. Summary. Stump appendicitis is an uncommon complication after appendectomy and may lead to serious complications. Management of low-grade appendiceal mucinous neoplasm (LAMN) is controversial, and we discuss the importance of the case. CONCLUSION: The case of young male post stump appendectomy with histopathology showing LAMN in the stump of the appendix, which to our knowledge, is the first in the medical literature and, discuss the stump appendicitis and incomplete appendectomy concerning malignancy, mucinous neoplasm, and adenocarcinoma.

Post-trauma transmesocolic hernia: a case report.

The prevalence of transmesocolic hernias, a subtype of internal hernias (IHs), is generally low. Its clinical consequences, including strangulation, ischemia and even death, however, necessitate awareness. IHs are classified as congenital or acquired as resulting from surgery, trauma or intraperitoneal inflammation. This is a case of a 37-year-old male victim of a motor vehicle collision 1 month prior to the index admission. The trauma-related injuries were managed conservatively and then discharged home. The patient was re-admitted with a 2-day history of epigastric pain, vomiting and abdominal distension. A diagnosis of small bowel obstruction due to a transmesocolic hernia was made on CT and emergency laparotomy performed. The post-operative course was unremarkable. It is vital to consider transmesocolic hernias in trauma patients presenting with a picture of bowel obstruction even in the absence of prior surgery.

Emphysematous Cholecystitis and Necrotizing Pancreatitis: Unusual Combination of Critical Pathology in a Healthy Young Patient.

Emphysematous cholecystitis (EC) is a rare form of severe cholecystitis, more common among old, frail males, with comorbidities like diabetes mellitus and peripheral vascular disease. The coexistence of emphysematous cholecystitis with necrotizing pancreatitis is extremely uncommon and in the literature, though it has been reported, no case was of a young patient like the one we are describing. He was treated with laparoscopic cholecystectomy, and his pancreatitis managed conservatively.

Adenocarcinoma of Stump Appendicitis: An Extremely Rare Pathology - A Literature Review.

Emergency appendectomy for acute appendicitis is the most common emergency surgical procedure performed all over the world. While amputating the appendix from the cecum, a small (usually less than 5 mm) stump is left behind. Below this, the suture or stapler is applied to secure the base of the appendix, which is now known as a stump. Stump appendicitis, the inflammation of appendiceal remnant after an appendectomy, is a rare phenomenon. Additionally, the incidence of adenocarcinoma in the stump of the appendix is also extremely rare and can present with the symptoms of appendicitis. Adenocarcinoma in stump appendectomy patients can present from 5-43 years after the index appendectomy surgery. The majority of patients present with symptoms similar to that of appendicitis, with right lower quadrant abdominal pain, usually diagnosed via CT scans, after which they undergo stump appendectomy. The diagnosis of adenocarcinoma is only made on the histopathology report. We engaged in a review of the relevant literature published in the English language for the last 100 years. This was conducted by reviewing Google Scholar, PubMed, and MEDLINE® databases, as well as references to all related articles. There are only six cases reported in the literature, which shows the rarity of this condition. Regarding the appropriate treatment for this rare entity, multi-disciplinary team discussions should be carried out for optimum management of the individual patients. Right hemicolectomy is the recommended procedure for all patients, and prognosis depends on the staging of the disease.

Peripartum Severe Acute Pancreatitis with Rare Complications: Case Report and Review of Literature.

Peripartum pancreatitis is a rare clinical condition that occurs usually in the third trimester of pregnancy. Pancreatitis is usually secondary to gallstones, and it can lead to life-threatening and rare complications. We report a case of necrotizing postpartum pancreatitis that developed abdominal compartment syndrome (ACS) in early course, posterior reversible encephalopathy syndrome (PRES), and splanchnic and extrasplanchnic thrombosis later on. Case. 31-year-old female, one week after delivery, presented to the emergency department with abdominal pain, nausea and vomiting, tenderness in the epigastrium, and raised pancreatic enzymes. Ultrasound (USG) showed bulky pancreas with gallstones. She was diagnosed as having acute biliary pancreatitis and started to be hydrated and was supplemented with analgesia. Her condition deteriorated on the 2nd day, and she was shifted to the surgical intensive care unit (SICU) where she developed abdominal compartment syndrome (ACS), respiratory distress, and acute kidney injury, requiring endotracheal intubation and ventilation. Computerized tomography (CT) showed pancreatic necrosis with multiple fluid collections and significant left-sided pleural effusion. Percutaneous drainage of pleural effusion was done, and she was stabilized to be weaned off from mechanical ventilation. On day 15, she underwent USG-guided drainage of the pancreatic collection and ERCP (endoscopic retrograde cholangiopancreatography) on day 19. Post-ERCP, she had tonic colonic convulsions which were treated with benzodiazepines and phenytoin. It was diagnosed by imaging studies as posterior reversible encephalopathy syndrome (PRES). Her abdomen was still distended and tender; CT showed a significant pseudocyst with splanchnic and extrasplanchnic thrombosis. She had laparotomy, gastrocystostomy, and cholecystectomy on day 28th. She made uncomplicated recovery and discharged in good health. Conclusion. Peripartum pancreatitis can be complicated by ACS, PRES, and splanchnic and extrasplanchnic thrombosis.

Heterotopic Gastric Mucosa Presenting as Lower Gastrointestinal Bleeding: An Unusual Case Report.

Heterotopic gastric mucosa (HGM) is gastric mucosal tissue outside the stomach. It can be discovered anywhere throughout the gastrointestinal tract and is mostly asymptomatic. HGM, although rare beyond the ligament of Treitz, should be included in the differential diagnosis in a young patient with a polyp causing obstructive symptoms or bleeding. Very few cases are published in literature. We describe a case of young male who presented with an episode of large amount of melena, from a bleeding jejunal lesion, diagnosed by endoscopy. Laparotomy and wedge resection of the jejunal lesion was done, and histopathology showed gastric heterotopia in a small jejunal diverticulum.

Rare occurrence of metastasis from lung cancer to the anus: case report and review of the literature.

BACKGROUND: Anal metastases from lung cancer are infrequent, and there are only 10 published cases. Life expectancy is no longer than 1 year after diagnosis because of the typically advanced stage of disease. Treatment, which is typically inefficient, is administered with the intent to cure or avoid local complications. CASE PRESENTATION: We report a case of a patient with non-small cell lung cancer presenting with perianal metastasis mimicking an abscess. CONCLUSIONS: Because perianal masses may be misdiagnosed, patients with lung and other cancers should be evaluated for metastatic disease.

Laparoscopy as a Diagnostic and Definitive Therapeutic Tool in Cases of Inflamed Simple Lymphatic Cysts of the Mesentery.

Mesenteric cysts are rare benign abdominal tumors. These cysts, especially those of lymphatic origin, very rarely become inflamed. The diagnosis of inflamed lymphatic cysts of the mesentery may be difficult. We herein report two cases of inflamed simple lymphatic cysts of the mesentery definitively diagnosed and excised by laparoscopy.

Unusual presentation of dermatofibrosarcoma protuberans in a male patient's breast: a case report and review of the literature.

We herein present a case report and literature review of dermatofibrosarcoma protuberans in the breast of a male patient. A 27-year-old man presented with a painless lump in his right breast with areas of bluish skin discoloration. The diagnostic work-up comprised clinical examination, ultrasonography, core biopsy, mammography, and magnetic resonance imaging. After surgical excision, the preoperative diagnosis of dermatofibrosarcoma protuberans was proven by pathological examination and immunohistochemistry. The patient was still free of recurrence 1 year after surgical excision. This extremely rare case is, to the best of our knowledge, the fifth such case reported in the literature.
