We present a case of a 79-year-old man with lower abdominal pain and negative Blumberg sign. An indwelling bladder catheter was inserted for urinary retention due to a tight phimosis 2 months earlier. A contrast-enhanced computed tomography scan revealed a huge gastrectasia and small bowel distention due to a suspected adherent bridle. The clinical signs and the laboratory tests were highly suspicious for bowel obstruction and emergency surgery was indicated. Exploratory laparoscopy showed a bladder hole tamponade by an ileum loop. The perforation was sutured laparoscopically and the patient was discharged on the 14th postoperative day. In our case, emergency laparoscopic exploration was useful for the diagnosis and the treatment of spontaneous bladder rupture. We hope this case report can be useful to give these patients better outcomes. Notably we would like to emphasize that the presence of a urinary catheter can be a risk factor for intraperitoneal bladder rupture.

In this note we describe the application of existing smart contract technologies with the aim to construct a new digital representation of a financial derivative contract. We compare several existing DLT based technologies. We provide a detailed description of two separate prototypes which are able to be executed on a centralized and on a DLT platform respectively. Beyond that we highlight some insights on legal aspects as well as on common integration challenges regarding existing process and system landscapes. For a further introductory note and motivation on the theoretical concept we refer to https://www.law.ox.ac.uk/business-law-blog/blog/2018/12/smart-derivative-contract-constructing-digital-financial-derivative . A very detailed methodological overview of the concept of a smart derivative contract can be found in doi:10.2139/ssrn.3163074., 51 pages, 7 figures

Eribulin mesylate is approved for the treatment of metastatic breast cancer after progression with anthracyclines and taxanes. Here we report the case of a woman with triple-negative breast cancer who, after nine lines of chemotherapy, showed striking primary tumor shrinkage and regression of metastatic lesions with eribulin treatment. This response allowed the patient to undergo debulking surgery. Even though the patient was heavily pretreated, eribulin was well tolerated and improved her quality of life. Biological analysis of tumor specimens was performed to investigate the underlying mechanism of action of the drug.

Purpose. This multicenter randomized study was designed to compare the clinical and functional results of stapled transanal rectal resection (STARR) performed with 2 staplers (PPH-01 vs. PPH-03) in the treatment of hemorrhoidal disease associated with a large internal rectal prolapse. Methods. From a total of 937 patients, referred for hemorrhoidal disease in the 20 centers involved in the study, 425 (45.3%) with prolapsed hemorrhoids associated with a large internal rectal prolapse were randomized to undergo STARR with PPH-01 or PPH-03. Postoperative evaluation was made at 3, 6, and 12 months. Results. The incidence of bleeding at the stapled line was significantly lower in the PPH-03 group than in the PPH-01 group (58/207 [28.0%] vs. 145/201 [72.1%]; P < .0001); the mean number of hemostatic stitches was significantly higher in the PPH-01 than in the PPH-03 group (3.2 ± 0.1 vs. 1.8 ± 0.8; P < .0001). The mean operative time was 25.1 ± 11.5 minutes in the PPH-03 group and 38.1 ± 15.7 minutes in the PPH-01 group ( P < .0001). No major complications occurred in either of the groups. At 12-month follow-up, the success rate in the 2 groups was 94.5% in the PPH01 group and 94.2% in the PPH03 group. Conclusion. STARR performed for the treatment of hemorrhoidal disease associated with a large rectal prolapse is a safe and effective procedure. The use of the PPH-03 stapler instead of the PPH-01 guarantees a statistically significant reduction of intraoperative bleeding and a significant decrease of the operative time.

The authors analyse clinical cases of penetrating thoracic, abdominal, perineal and anorectal injury and describe the traumatic event and type of lesion, the principles of surgical treatment, the complication rate and follow up.In the last 24 months, we analyzed 10 consecutive cases of penetrating thoracic and abdominal wounds [stab wound (n=7), with evisceration (n=4), gunshot wound (n=1)], and penetrating perineal and anorectal wounds (impalement n=4). In addition, we report an unusual case of neck injury from a stab wound. All the patients underwent emergency surgery for the lesions reported.In 7 cases of perforating vulnerant thoracoabdominal trauma from stab wounds there was hemoperitoneum due to bleeding from the abdominal wall (n=3), the omentum (n=1), the vena cava (n=1) and the liver (n=2). Evisceration of the omentum was observed in 4 cases. In 2 cases laparoscopy was performed. In one case laparotomy and thoracoscopy was performed. In a patient with an abdominoperineal gunshot wound, exploration was extraperitoneal. The 4 cases of perineal and anorectal impalement were treated with primary reconstruction, while in one case a laparotomy was needed to suture the rectum and fashion a temporary colostomy. In one case of anorectal injury rehabilitation resulted in a gradual improvement of fecal continence, while in the patient with the colostomy follow up at 2 months was scheduled to plan colostomy closure.Based on the our clinical experience and the literature, in penetrating abdominal trauma laparotomy may be required if patients are hemodynamically unstable (or in hemorrhagic shock), in patients with evisceration and peritonitis, or for exploration of penetrating thoracoabdominal and epigastric lesions. In anterior injuries of the abdominal wall from gunshot or stab wounds, laparotomy is indicated when there is peritoneal violation and significant intraperitoneal damage. In patients with actively bleeding wounds of the abdominal wall muscles minimal laparotomy is often necessary for control of hemorrhage and abdominal wall reconstruction to avoid herniation. If patients are asymptomatic, in cases of anterior lesions the indications for diagnostic laparoscopy are uncertain. Selective conservative treatment is reserved for asymptomatic patients who are hemodynamically stable. Further controlled studies are needed. Early surgery for perineal and anorectal trauma, and also for complex injuries, is the gold standard for treatment.
