AbstractThe water-jet hydro dissection technique has been shown to be effective for colorectal tumors. This case report illustrates type T hybrid knife for the elevation of the submucosal layer, cutting the mucosa and dissecting submucosal fibers. ESD was performed using ERBEJET 2 hydrodissection system and hybrid Knife. The resection was completed en bloc within 135 minutes without adverse events. Pathology examination revealed a well-differentiated adenocarcinoma confined to the shallow submucosal layer with free resection margins.

A 68-year-old female was operated for a giant dedifferentiated retroperitoneal liposarcoma (RLS) encasing entirely the right kidney. She had an en-bloc resection of the tumor with right nephrectomy. The en-bloc resection should avoid R1 resection margins. Renal conservation is suggested if the kidney is widely displaced and for elderly patient.

Aim: to identify the risk factors for conversion of endoscopic submucosal dissection to abdominal surgery.Patients and methods: the prospective cohort study included 405 patients: 166 (40.9%) males and 239 (59.1%) females. The median age was 66 (59; 72) years old; the patients underwent endoscopic submucosal dissection of colorectal epithelial neoplasms.Results: the median size of the removed neoplasms was 3.0 (2.4; 4) cm, tumor was removed en bloc in 324/363 (89.2%) cases; and R0 resection margins were detected in 218/324 (67.3%) cases. Significant risk factors for conversion were: the tumor size ≥ 3.2 cm (OR 2.9, 95% CI 1.2–7.1, p = 0.017), lifting ≤ 3 mm (OR 41, 95% CI 15–105, p = 0.000002) and the tumor vascular pattern IIIa according Sano’s capillary pattern classification (OR 4.0, 95% CI 1.3–11.9, p = 0.013).Conclusion: endoscopic submucosal dissection is a safe way to remove colorectal neoplasms. However, the presence of conversion risk factors can influence the outcome of endoscopic treatment.

Chordomas are rare, locally aggressive neoplasms that develop from remnants of the notochord. The typical approach to chordomas of the clivus and axial cervical spine often limits successful en bloc resection. In this case report, authors describe the first-documented transoral approach using both transoral robotic surgery (TORS) for exposure and the Sonopet bone scalpel under navigational guidance to achieve en bloc resection of a cervical chordoma. This 27-year-old man had no significant past medical history (Charlson Comorbidity Index 0). During a trauma workup following a motor vehicle collision, a CT of the patient’s cervical spine demonstrated an incidental 2.2-cm lesion situated along the posterior aspect of the C2 vertebral body. Postoperative imaging showed successful en bloc resection with adequate placement of hardware, and the pathology report demonstrated negative resection margins. The patient tolerated the procedure well, and because of the successful en bloc resection, radiation has been deferred. At 7 months postoperatively, the patient returned to work in New York City. Contrasted MRI at 15 months postoperatively showed the patient to be disease free. This approach offers a promising way forward in the treatment of these complex tumors.

Abstract Background Lipoleiomyoma is a rare, benign variant of the commonplace uterine leiomyoma. Unlike leiomyoma, these tumors are composed of smooth muscle cells admixed with mature adipose tissue. While rare, they are most frequently identified in the uterus, but even more infrequently have been described in extrauterine locations. Case presentation We describe a case report of a 45-year-old woman with a history of in vitro fertilization pregnancy presenting 6 years later with abdominal distention and weight loss found to have a 30-cm intra-abdominal lipoleiomyoma. While cross-sectional imaging can narrow the differential diagnosis, histopathological analysis with stains positive for smooth muscle actin, desmin, and estrogen receptor, but negative for HMB-45 confirms the diagnosis of lipoleiomyoma. The large encapsulated tumor was resected en bloc. The patients post-operative course was uneventful and her symptoms resolved. Conclusions Lipoleiomyoma should be considered on the differential diagnosis in a woman with a large intra-abdominal mass. While considered benign, resection should be considered if the mass is symptomatic, and the diagnosis is unclear or there is a concern for malignancy.

Abstract Background Gall bladder cancer (GBC) is the fifth most common malignancy in the gastrointestinal system and the most common malignancy of the biliary system. GBC is a very aggressive malignancy having a 5 year survival rate of 19%. Giant Gall Bladder (GGB) is an uncommon condition that can result from cholelithiasis or chronic cholecystitis and rarely with malignancy. Case report A 65 year old lady presented with vague abdominal pain for 12 years and right abdominal lump of size 20 × 8 cms was found on examination. CT scan showed a circumferentially irregularly thickened wall (2.5 cm) of gall bladder indicative of malignancy. Per-operatively a GB of size 24 × 9 cm was noted and patient underwent radical cholecystectomy. It was surprise to find such a giant malignant GB with preserved planes. Histopathology, it was well differentiated adenocarcinoma of gall bladder of Stage II (T2a N0 M0). Discussion It is known that mucocoele of GB can attain large size, however chronic cholecystitis will lead to a shrunken gall bladder rather than an enlarged one. A malignant GB of such size and resectable is rare without any lymph node involvement or liver infiltration. Few cases of giant benign gall bladder have been reported in literature, however this appears to be the largest resectable gall bladder carcinoma reported till date as per indexed literature. Conclusion Giant GB is an uncommon finding. They are mostly benign, however malignant cases can occur. Radiological findings may suggest features of malignancy and define extent of disease. Prognosis depends on stage of disease and resectability, irrespective of size.

AbstractIntroduction:Verrucous carcinoma is a variant of well differentiated squamous cell carcinoma characterised by an exophytic, warty growth which is slowly but locally invasive and which can cause extensive local destruction if left untreated.Case report:We report the first known case of veruccous carcinoma of the paranasal sinuses with rapid orbital invasion. A 58-year-old man presented with right-sided nasal obstruction, a huge right intranasal lesion, intractable dacryocystitis and cutaneous involvement of the nasolacrimal sac region. The tumour was partially removed using an endoscopic transnasal approach. Post-operatively, and while waiting for the histological result, the patient developed signs of rapid invasion of the orbit, with uniocular visual acuity deficit. He underwent combined radiochemotherapy, with a moderate response.Conclusion:Knowledge of the potentially aggressive nature of verrucous carcinoma may be helpful in early management of intraorbital invasion and salvaging of the eye.
