Profunda femoris pseudoaneurysm rupture post dynamic hip screw fixation after physiotherapy.

This case discusses an elderly female who presented acutely with compromised profunda femoris pseudoaneurysm and massive haematoma five weeks after dynamic hip screw insertion for a left neck of femur fracture. The only precipitating factor leading to this presentation was ongoing physiotherapy. She was referred from a rehabilitation hospital to the nearest vascular surgical unit for acute and definitive surgical intervention. Post-operatively, she fared incredibly well, regaining her baseline level of functioning. History taking is complex in a patient with dementia. Clinical examination should follow with a focused approach to the site of recent operation and also where complications are likely to manifest when an alteration from baseline cognitive function is noted. This is of course in addition to the complete work up required from a holistic perspective with any acute deterioration. Imaging should be arranged and prompt referral made if a treatable acute cause is identified. It is imperative to involve family and/or next of kin if possible, but this should not impede prompt decision-making in the patient's best interests by the clinical team if delays are likely to occur.

Perioperative Safety in Patient Under Oral Anticoagulation During Holmium Laser Enucleation of the Prostate.

INTRODUCTION AND OBJECTIVES: To evaluate the safety of holmium laser enucleation of the prostate (HoLEP) in patients on oral anticoagulation (OA) with respect to intra- and postoperative bleeding complications. METHODS: Between January 2013 and October 2016, 2178 patients were included in this study, of whom 94 received direct oral anticoagulants (DOACs) and 151 received vitamin K antagonists (VKAs) before HoLEP. All patients either ceased OA (DOACs) or were bridged subtherapeutically (VKAs, international normalized ratio <2) during surgery. These patients were compared to a sample size of 1933 nonanticoagulated patients. RESULTS: A significant longer postoperative stay was noted for the patients on DOACs (5.2 [4-6] days) and VKAs (5.3 [4-5] days) compared to the control group (4.5 [4-4] days). The mean drop in hemoglobin was significantly higher in the VKA group compared to the DOAC and control group. There was a significantly higher rate of postoperative bladder tamponades/secondary coagulation in patients on OA with 6 (7.9%)/3 (3.9%) patients in the DOAC group, 10 (7.4%)/6 (4.4%) patients in the VKA group compared to 37 (2.2%)/21 (2.1%) patients in the control group, respectively (p < 0.001). Eight patients required blood transfusions with a distribution of 1 (1.3%), 3 (2.2%), and 4 (0.2%) patients in the DOAC, VKA, and control group, respectively (p < 0.001). CONCLUSIONS: Our findings indicate that bridged patients who's DOACs and VKAs were ceased before HoLEP are at higher risk of intra- and postoperative bleeding complications. Nonetheless, HoLEP appears to be a safe and effective procedure in those patients.

A nomogram predicting re-operation due to secondary hemorrhage after monopolar transurethral resection of prostate.

We aim to develop a nomogram to predict re-operation due to secondary hemorrhage after Monopolar transurethral resection of the prostate (M-TURP). We identified patients undergoing M-TURP at Peking University First Hospital from 2000 to 2013. Univariate and multivariate logistic regression models were developed to predict the occurrence re-operation due to secondary hemorrhage. The discriminatory ability of the nomogram was tested using the area under the receiver operating characteristic curve (ROC), and internal validation was performed via bootstrap resampling. Of the 1901 patients who underwent M-TURP during the study period, 9.1% (173 patients) experienced hemorrhage after M-TURP, and they had a 22.0% re-operation rate (38 patients). Benign prostatic hyperplasia (BPH)-related complications (odds ratio, 0.386; 95% CI, 0.177-0.841), percent of resected prostate (OR, 0.156; 95% CI, 0.023-1.060) and suprapubic cystostomy (OR, 0.298; 95% CI, 0.101-0.881) were independently associated with re-operation. The nomogram accurately predicted re-operation (area under the ROC curve 0.718). The negative predictive value was 88.0%, while the positive predictive value was 47.9%. Re-operation due to secondary hemorrhage after M-TURP was associated with no BPH-related complications, lower percent of resected prostate and no suprapubic cystostomy and was accurately predicted with using the nomogram.

Evolution in the Treatment of Delayed Postpancreatectomy Hemorrhage: Surgery to Interventional Radiology.

OBJECTIVES: We summarized a single center's evolution in the management of postpancreatectomy hemorrhage (PPH) from surgical toward endovascular management. METHODS: Between 2003 and 2013, 337 patients underwent Whipple procedures. Using the International Study Group of Pancreatic Surgery (ISGPS) consensus definition, patients with PPH were identified and retrospectively analyzed for the presentation of hemorrhage, type of intervention, and 90-day mortality outcome measures. RESULTS: Management evolved from operative intervention alone, to combined operative and on-table angiographic intervention, to endovascular intervention alone. The prevalence of PPH was 3.0%. Delayed PPH occurred with a mean of 13.8 days. On angiography, visceral arteries affected were the gastroduodenal artery, hepatic artery, jejunal branches of the superior mesenteric artery, pancreaticoduodenal artery, and inferior phrenic artery. Ninety-day mortality for PPH was 20%. From early to recent experience, the mortality rate was 100% for operative intervention alone, 25% for combined operative and on-table angiographic intervention, and 0% for endovascular intervention alone. CONCLUSIONS: Our 10-year experience supports current algorithms in the management of PPH. Key considerations include the recognition of the sentinel bleed, the presence of a pancreatic fistula, and the initial operative role of a long gastroduodenal artery stump with radiopaque marker for safe and effective embolization should PPH occur.

Efficacy and safety of over-the-scope clip: including complications after endoscopic submucosal dissection.

AIM: To retrospectively review the results of over-the-scope clip (OTSC) use in our hospital and to examine the feasibility of using the OTSC to treat perforations after endoscopic submucosal dissection (ESD). METHODS: We enrolled 23 patients who presented with gastrointestinal (GI) bleeding, fistulae and perforations and were treated with OTSCs (Ovesco Endoscopy GmbH, Tuebingen, Germany) between November 2011 and September 2012. Maximum lesion size was defined as lesion diameter. The number of OTSCs to be used per patient was not decided until the lesion was completely closed. We used a twin grasper (Ovesco Endoscopy GmbH, Tuebingen, Germany) as a grasping device for all the patients. A 9 mm OTSC was chosen for use in the esophagus and colon, and a 10 mm device was used for the stomach, duodenum and rectum. The overall success rate and complications were evaluated, with a particular emphasis on patients who had undergone ESD due to adenocarcinoma. In technical successful cases we included not only complete closing by using OTSCs, but also partial closing where complete closure with OTSCs is almost difficult. In overall clinical successful cases we included only complete closing by using only OTSCs perfectly. All the OTSCs were placed by 2 experienced endoscopists. The sites closed after ESD included not only the perforation site but also all defective ulcers sites. RESULTS: A total of 23 patients [mean age 77 years (range 64-98 years)] underwent OTSC placement during the study period. The indications for OTSC placement were GI bleeding (n = 9), perforation (n = 10), fistula (n = 4) and the prevention of post-ESD duodenal artificial ulcer perforation (n = 1). One patient had a perforation caused by a glycerin enema, after which a fistula formed. Lesion closure using the OTSC alone was successful in 19 out of 23 patients, and overall success rate was 82.6%. A large lesion size (greater than 20 mm) and a delayed diagnosis (more than 1 wk) were the major contributing factors for the overall unsuccessful clinical cases. The location of the unsuccessful lesion was in the stomach. The median operation time in the successful cases was 18 min, and the average observation time was 67 d. During the observation period, none of the patients experienced any complications associated with OTSC placement. In addition, we successfully used the OTSC to close the perforation site after ESD in 6 patients. This was a single-center, retrospective study with a small sample size. CONCLUSION: The OTSC is effective for treating GI bleeding, fistulae as well as perforations, and the OTSC technique proofed effective treatment for perforation after ESD.

[Complications of central venous access devices: outcome analysis of 2359 implantations]. / Komplikationen zentralvenöser Portsysteme: Erfahrungsbericht über 2359 Implantationen.

BACKGROUND AND OBJECTIVE: The implantation of venous access devices is of great importance in the treatment of oncological patients. Such systems allow a safe application of highly efficacious drugs with great comfort for the patient. Knowing the rate of complications, is wide indication for such implantations justified? METHODS: From July 1 (st), 1995 to December 31 (st), 2003, 2359 access systems were implanted under local anaesthesia mainly for chemotherapy. All patients were examined for postoperative complications and followed up throughout the complete duration of treatment. RESULTS: In 147 out of 2359 patients we saw complications which had to be treated. In all cases treatment was effective. No patient suffered severe consequences. Main complications were infections (2.4%), and thrombosis (2.0%). In 17 cases (0.7%) bleeding occurred postoperatively which required reoperation in 12 patients. We saw 5 instances of pneumothorax after puncture of the subclavian vein four of which were drained. In 11 cases (0.5%) we found dislocation of the catheter. In 10 cases we were able to reposition the catheter by open procedure, and only in one patient was repositioning not successful. In three cases (0.1%) there occurred disconnection between access catheter and access chamber with extravasation in two cases. In one patient the catheter had to be removed surgically out of the right atrium. CONCLUSION: The implantation of venous access systems under local anaesthesia is a safe procedure with a low rate of complications and allows permanent venous access with very acceptable comfort for the patient. The indication for implantation can therefore be set liberally.
