Early postoperative anastomotic obstruction after colorectal surgery rarely develops. Herein, we present a case of a 50-year-old healthy woman who had an early postoperative anastomotic obstruction which was revealed caused by a blood clot and successfully managed by endoscopic approach. The patient was discharged after laparoscopic anterior resection and visited the emergency department one day after because of abdominal pain. Computed tomography showed that the anastomosis site was obstructed with low-density material. Intraoperative endoscopy was performed under general anesthesia and blood clot filling the lumen were identified. As the scope was advanced to the blood clot with air inflation, the blood clot was evacuated. The anastomosis site could be obstructed by blot clot with mucous debris albeit it is a rare condition. An endoscopic approach seems to be the first option in the diagnosis and treatment of postoperative obstruction at the anastomosis site and it could prevent unnecessary laparotomy.

Pelvic kidney, an ectopic renal mass caused by developmental failure, is a rare condition. Here, we report a case of laparoscopic anterior resection in a patient with a solitary pelvic kidney. A 76-year-old man was diagnosed as having rectosigmoid colon cancer. Preoperative computed tomography revealed a left ectopic kidney in his pelvis. Computed tomographic angiography and retrograde pyelography were performed preoperatively to identify the renal vessels and the ureter. To keep the surgical plane intact for complete mesocolic excision, a complete laparoscopic anterior resection was safely performed without open conversion, and there was no injury to the pelvic kidney. The patient was discharged on postoperative day eight without any complication. No deterioration of renal function was observed after surgery. This report describes a case of laparoscopic anterior resection that was safely performed without conversion to open surgery in a patient with a pelvic ectopic kidney.

Objective: To evaluate the association of serum malondialdehyde low-density lipoprotein (MDA-LDL), an oxidatively modified LDL, with the prevalence of high-risk plaques (HRP) determined with coronary computed tomography angiography (CTA) in statin-treated patients. Methods: This study was a single-center retrospective cohort comprising 268 patients (mean age 67 years, 58% men) with statin therapy and who underwent coronary CTA for suspected stable coronary artery disease. Patients were classified into two groups according to median MDA-LDL level or median LDL-C level. Coronary CTA-verified HRP was defined when two or more characteristics, including positive remodeling, low-density plaques, and spotty calcification, were present. Results: Patients with HRP had higher MDA-LDL (p = 0.011), but not LDL-C (p = 0.867) than those without HRP. High MDA-LDL was independently associated with HRP (odds ratio 1.883, 95% confidential interval 1.082–3.279) after adjustment for traditional risk factors. Regarding incremental value of MDA-LDL for predicting CTA-verified HRP, addition of serum MDA-LDL levels to the baseline model significantly increased global chi-square score from 26.1 to 32.8 (p = 0.010). Conclusions: A high serum MDA-LDL level is an independent predictor of CTA-verified HRP, which can lead to cardiovascular events in statin-treated patients.

Abstract Objective This study aimed to compare the necessary scutum defect for transmeatal visualisation of middle-ear landmarks between an endoscopic and microscopic approach. Method Human cadaveric heads were used. In group 1, middle-ear landmarks were visualised by endoscope (group 1 endoscopic approach) and subsequently by microscope (group 1 microscopic approach following endoscopy). In group 2, landmarks were visualised solely microscopically (group 2 microscopic approach). The amount of resected bone was evaluated via computed tomography scans. Results In the group 1 endoscopic approach, a median of 6.84 mm3 bone was resected. No statistically significant difference (Mann–Whitney U test, p = 0.163, U = 49.000) was found between the group 1 microscopic approach following endoscopy (median 17.84 mm3) and the group 2 microscopic approach (median 20.08 mm3), so these were combined. The difference between the group 1 endoscopic approach and the group 1 microscopic approach following endoscopy plus group 2 microscopic approach (median 18.16 mm3) was statistically significant (Mann–Whitney U test, p < 0.001, U = 18.000). Conclusion This study showed that endoscopic transmeatal visualisation of middle-ear landmarks preserves more of the bony scutum than a microscopic transmeatal approach.

Laparoscopic Anterior Resection

Anterior resection for the treatment of full thickness rectal prolapse has been around for over four decades. 1 However, its use has been limited due to fear of anastomotic leakage and related morbidity. It has been shown that high anterior resection is preferable to its low counterpart as the latter increases complication rates. 2 Although sparing the inferior mesenteric artery in sigmoid resection for diverticular disease has been shown to decrease leak rates in a randomized setting, 3 vascular division is current practice. We shall callenged this current practice of dividing the mesorectum in anterior resection for complete rectal prolapse developing a technique that allows the preservation of the superior rectal artery.
