CEA levels in serum and BAL in patients suffering from lung cancer: correlation with individuals presenting benign lung lesions and healthy volunteers.

BackgroundCarcinoembryonic antigen (CEA) is a tumor marker belonging to the immunoglobulin gene superfamily of adhesion molecules. CEA is synthesized by epithelial and tumor cells. In this study, CEA levels in sera and bronchoalveolar lavage fluid (BAL) were measured in patients with malignant lung cancer and benign lung diseases.MethodsIn the present study CEA was measured in serum using IRMA methods and in bronchoalveolar lavage of individuals undergoing fiberoptic bronchoscopy. Fifty patients with lung cancer (G1), 20 patients with benign lung lesions (G2), and a control group consisted of 20 individuals (G3) were enrolled in the study.ResultsWe found that serum CEA levels were significantly higher in G1 compared to G2 and G3 (p < 0.01). No significant difference in serum CEA levels was found between smokers and nonsmokers in any of the three groups studied. CEA was significantly higher in G1 BAL (p < 0.05) compared to G2 and G3 BAL. Furthermore, a statistically significant difference was found in CEA levels in BAL between smokers and nonsmokers of G2.ConclusionsCEA levels in BAL of normal individuals may be influenced by smoking and other factors that affect lung epithelial cell function. Thus, CEA measurement in BAL alone has little value in the diagnosis of malignancy. BAL CEA levels in smokers of G2 are found significantly higher compared with nonsmokers of the same group and healthy individuals. Smokers of G2 have to be followed up carefully for the possibility of lung cancer growth.

Diabetes mellitus type I associated with dermatomyositis: an extraordinary rare case with a brief literature review

Insulin dependent diabetes mellitus (IDDM) is considered to be an autoimmune disease. IDDM is associated with other autoimmune diseases such as rheumatoid arthritis, autoimmune thyroid disease, multiple sclerosis, ankylosing spondylitis, psoriasis and systemic lupus erythematosus. Dermatomyositis (DM) is a disease of autoimmune aetiology involving skin and skeletal muscles damaged by an inflammatory process dominated by lymphatic infiltration. The association of IDDM with DM is extraordinarily rare. To our best knowledge, to date only two reports—one of them referring to a patient in childhood—have been published worldwide. DM and IDDM affect children and young adults. Herein, a case of DM in association with IDDM in a 28-year-old man is presented.

Gastric conduit obstruction due to gastroduodenal compression: a new complication post-Ivor–Lewis oesophagectomy

Abstract Introduction: Oesophagectomy for oesophageal carcinoma carries a high risk of significant morbidity and mortality. Delayed gastric emptying is a relatively common complication following this procedure. A variety of medical, surgical and endoscopic strategies have been described to manage it. The vast majority of cases are related to post-operative pyloric dysfunction and are amenable to conventional management strategies. Patients and methods: We present a new case of a patient with a duodenal hiatus hernia resulting in extrinsic gastroduodenal compression by the massively distended gastric conduit as a cause of gastric outlet obstruction following laparoscopic-assisted Ivor–Lewis oesophagectomy 2 years previously. Results and conclusions: Surgical repair of the hiatus hernia restored the post-oesophagectomy anatomy and resolved this patient’s symptoms where conventional management of post-oesophagectomy gastric outlet obstruction had failed on multiple occasions. Most cases of delayed gastric emptying post-oesophagectomy occur as a result of pyloric dysfunction and can be managed using a combination of prokinetics, surgical intervention or more commonly, endoscopic dilatation. Other potential causes and therefore investigative and management strategies should be considered in patients who repeatedly fail conventional management. We offer an alternative diagnosis that may be considered in these patients and present a novel approach to their investigation and management.

Chronic ileitis with transmural migration of ingested foreign body treated by laparoscopy

Abstract Background: Ingestion of foreign bodies such as fish bone or chicken bone is relatively common in adults; however, resultant transmural migration is extremely rare. Methods: We present a case of a 79-year-old woman with chronic low-grade abdominal pain, worsening over the last 4 days. Computed tomography revealed segmental small bowel wall thickening with chronic inflammation suggestive of Crohn’s ileitis and oral steroids were commenced; only later, ingestion of a foreign body was suspected. Results and conclusion: At diagnostic laparoscopy, a linear foreign body resembling a wooden splinter was identified. It had partly migrated through the chronically inflamed bowel wall without causing perforation or abdominal contamination. It was removed laparoscopically without an enterotomy or bowel resection. Microscopy revealed non-viable bone, likely fish or chicken bone. The patient made an uneventful recovery and was discharged 3 days later. Herein we emphasise on the differential diagnosis and presentation of chronically ingested foreign bodies, as well as the feature of chronic ileitis with uncomplicated transmural migration of the ingested foreign body that was treated laparoscopically without an enterotomy.

Transmural migration of azygous vein Hem-O-lok clip causing food bolus 3 months following uneventful minimally invasive oesophagectomy

Abstract Background: Hem-o-lok clips are widely deployed in various laparoscopic and robotic operations. Their migration is not very common and majority of reported cases are limited to biliary, prostatic and vesico-urethral cases. Methods: Herein, we would like to report the first case of transmural migration of Hem-o-lok clip from azygous vein stump following totally minimally invasive two-stage oesophagectomy for squamous cell carcinoma of the distal oesophagus, into the gastric conduit 3-months following uneventful discharge. The patient presented with 5-days history of worsening dysphagia. Results: The subsequent gastroscopy revealed normal gastric conduit with two Hem-o-lok clips containing the azygous vein stump within its lumen at the level of the oesophago-gastric anastomosis, propagating a food bolus obstruction. The foreign body was successfully removed and the patient was discharged the same day without any complications at 5 months follow up. Conclusion: Hem-o-lok clip migration trends to be a well-established event. However, their mechanism and exact incidence remains elusive to this date. To the best of our knowledge, their migration in oesophageal cancer surgery has not been reported.

Thoracoscopic total esophagogastrectomy with supercharged colon interposition for the treatment of esophageal adenocarcinoma in situs inversus

Abstract Background: Esophagectomy in situs inversus is challenging. With long-segment supercharged reconstruction, it becomes more perplexing and multidisciplinary surgical skills are needed. Challenges met and the surgical technique used is presented in this case report. Methods: The case of a 49-year old patient with situs inversus abdominus and a locally advanced distal esophageal adenocarcinoma extending to the stomach is presented. Results: Following neoadjuvant chemotherapy and due to inability to use the stomach as a conduit, a thoracoscopic total esophagogastrectomy with long-segment reconstruction was performed. The conduit used was the left colon and was supercharged with venous and arterial anastomoses in the neck. Conduit perfusion, as assessed by the Spy system revealed marked improvement post supercharging. No anastomotic leak was noted and oral diet was started on day 4. On day 26 the patient developed pneumonia necessitating intubation that was declined. Organ support was withheld with patient death at day 29. Conclusion: In long-segment esophageal reconstruction with supercharged colon, although thoracoscopy is feasible, laparoscopy is found unsafe. Careful preoperative planning and colon assessment via computed tomography(CT) colonography/angiography and a multidisciplinary team approach is recommended. Adjuncts to assess conduit perfusion like the Spy system are helpful. Supercharging the long colonic conduit is a way of minimizing ischemia-related complications.

A rare presentation of an acute appendicitis.

Abstract Paraumbilical hernia sac usually contains omentum, bowel loop and rarely appendicular epiploicae, metastatic deposits and vermiform appendix. Presentation of acute appendicitis in a paraumbilical hernia is rare and limited to few case reports in the literature. Herein, we would like to report a case of a successfully treated acute appendicitis presenting in a paraumbilical hernia in an 84-year-old lady with 6-month follow-up.

Subtle presentation of jejunal lipomata with intussusception in a young adult

Abstract Lipomas of gastrointestinal (GI) tract could occur at any anatomical level and represent 1–2% of all GI tumours. Amongst them, <2% are noted in jejunum and almost all in later decade of life with varied and non-specific symptoms. Their intussusception is even rarer and mostly present with full obstructive symptoms. Herein, we would like to report a successfully treated case of subtle jejunal lipomata with intussusception in an otherwise healthy a 21-year-old female.

Laparoscopic transgastric removal of eroding gastric band: a different approach.

Gastric banding is a popular method for the treatment of morbid obesity. Amongst complications, gastric erosion remains uncommon but could prove fatal. Multiple techniques, from open surgery to endoscopic and standard laparoscopic technique for their removal, have been previously detailed in the literature. However, only a few reports have mentioned their total laparoscopic transgastric removal in the literature. Herein, we report a successful removal of an eroding gastric band with its technical suggestion in a 43-year-old female patient 22 months following its application.

Association between Oesophageal Diverticula and Leiomyomas: A Report of Two Cases.

We report two rare cases of female patients presenting with oesophageal leiomyoma associated with oesophageal diverticulum, both of whom were surgically managed. Oesophageal leiomyoma and oesophageal diverticulum are uncommon as separate entities and rare as combined disease presentation. Clinicians need to be aware of the rare combination of the two entities and need to be able to exclude the presence of a tumour (benign or malignant) within a diverticulum and so plan the optimum treatment. Herein, we present two cases of oesophageal leiomyoma within oesophageal diverticulum and we try to elucidate the association between the two. To date, there is no consensus whether a diverticulum is secondary to a leiomyoma or, on the contrary, a leiomyoma arises within a diverticulum.
