Complete mesocolic excision (CME) in right-sided colon cancers appears to confer oncological benefits compared to conventional colectomy. Identification of the superior mesenteric vein (SMV) remains challenging. We describe the novel use of intra-operative robotic ultrasound scan (rUSS) in obese patients (BMI ≥ 29). All consecutive patients having robotic CME for colon cancer between 2014 and 2017 were included in this retrospective cohort study. Data were recorded on an ethics approved prospective database and included patient demographics, clinical and oncological outcomes. Patients were divided into group 1 (BMI ≤ 28) and group 2 (BMI ≥ 29). SMV first approach was employed in all cases and SMV detection was aided using rUSS in group 2. Primary outcome was postoperative morbidity. Secondary outcomes included conversion rate, operative time and length of stay (LOS). 41 (group 1, median 66 years) were compared to 32 patients (group 2, median 63 years). There were no conversions to laparoscopy or laparotomy. Median operative times for group 2 were 30 min longer (186 vs. 216 min, p = 0.05). Overall morbidity was similar (20% vs. 19% in group 1 and 2, p = 0.26). There was no significant difference between the two groups with regard to LOS (median 7 vs. 6 days, p = 0.48), readmissions (2 vs. 5, p = 0.13), R0 resection rate (98% vs. 94%, p = 0.43) and lymph node harvest (median 31 vs. 30, p = 0.28).CME can be technically more challenging than conventional colectomy in obese patients and is associated with longer operative times. The use of rUSS in obese patients can help to identify SMV and allow safer dissection.

A 52-year-old woman, who is a carrier of MLH-1 mutation (HNPCC-type Lynch syndrome) with a history of colon adenocarcinoma, was diagnosed with a 26 mm lobulated contrast-capturing mass located caudally of the pancreas tail, anteromedial of the spleen and medial of the splenic colon angle. She underwent an exploratory laparotomy with resection of the tumor. Initially, this mass was presumed to be metastasis in a patient with a history of colon adenocarcinoma. However, after further histopathological and immunohistochemical examination, the mass appeared to be a rare PEComa. Only a few cases of a PEComa in this retroperitoneal perirenal location have been described.

A 52-year-old male and 55-year-old female underwent surgical resection of a voluminous symptomatic epiphrenic diverticulum via a right thoracotomy. A formal myotomy of the distal esophagus was not performed. The first patient had an uncomplicated recovery whilst the other patient still suffers from an esophageal-cutaneous fistula and repetitive abscesses, treated by intravenous antibiotics and percutaneous drainage. The authors discuss the indication for resection, surgical techniques and complications.

Background Carotid endarterectomy (CEA) reduces the risk for stroke in patients with internal carotid artery stenosis. The optimal surgical technique remains subject of debate. Literature suggests patch angioplasty reduces complication risk. However, primary closure shortens cross-clamp times and eliminates graft-specific complications. This study aimed to assess complication rate after CEA with selective patching. Methods A total of 213 consecutive CEAs over a 3-year period from January 5th, 2011 to December 19th, 2013 were retrospectively analyzed. Postoperative complications were evaluated within 1 month after surgery. Results Primary closure was used in 110 operations and patch angioplasty in 103 procedures. Primary closure was performed when the carotid artery had a diameter above 5 mm, when there was a high carotid bifurcation, and when the contralateral carotid artery was occluded. After primary closure, we found 4 (3.6%) complications: 2 (1.8%) bleeding and 2 (1.8%) cranial nerve damage. After patch angioplasty 5 (4.9%) complications occurred: 1 (1.0%) bleeding, 2 (1.9%) cranial nerve damage, 1 (1.0%) cerebrovascular event, and 1 (1.0%) cerebral hyperperfusion resulting in mortality. There was no higher complication risk after primary closure ( P = 0.68). Clamp time was significantly longer when using patch angioplasty ( P Conclusions Primary closure appears to be an equivalent closure technique compared with patch angioplasty when used in selected patients.
