Delayed superficialization of brachiobasilic fistula: technique and initial experience

HYPOTHESIS: Angioaccess procedures for dialysis have varied patency rates with frequent need for intervention. A superficialized arteriovenous brachiobasilic fistula created as a 2-step procedure will have good long-term patency with minimal complication. DESIGN: Retrospective medical record review and patient interview. SETTING: Tertiary referral university hospital. PATIENTS: Twelve patients who underwent delayed superficialization of brachiobasilic fistula from September 1994 to April 2000. MAIN OUTCOME MEASURES: Patency of fistula for dialysis, and major and minor complications, including revisions. RESULTS: Delayed superficialization of brachiobasilic fistula was performed in 12 patients. Fistulas have been used for a mean duration of 22.4 months (range, 10-59 months). Two patients required alternate access owing to thrombosis of brachiobasilic fistula. CONCLUSIONS: The delayed superficialized brachiobasilic arteriovenous fistula has a good initial patency rate with minimal complications. It should be considered early in patients if radiocephalic fistula is unavailable.     

Colonoscopic Perforation Management by Laparoendoscopy: An Algorithm

Background and Objectives:

The role of laparoscopy in the management of iatrogenic colonoscopic injuries has increased with surgeons becoming facile with minimally invasive methods. However, with a limited number of reported cases of successful laparoscopic repair, the exact role of this modality is still being defined. Drawing from previous literature and our own experiences, we have formulated a simple algorithm that has helped us treat colonoscopic perforations.

Methods:

A retrospective review was undertaken of patients treated for colonoscopic perforations since the algorithm''s introduction. For each patient, initial clinical assessment, management, and postoperative recovery were carefully documented. A Medline search was performed, incorporating the following search words: colonoscopy, perforation, and laparoscopy. Twenty-three articles involving 106 patients were identified and reviewed.

Results:

Between May 2009 and August 2012, 7 consecutive patients with colonoscopic perforations were managed by 2 surgeons using the algorithm. There were no complications and no deaths, with a mean length of stay of 4.43 days (range, 2–7 days). Of the 7 patients, 6 required surgery. A single patient was managed conservatively and later underwent an elective colon resection.

Conclusions:

Traditionally, laparotomy was the preferred method for treating colonoscopic perforations. Our initial experience reinforces previous views that laparoendoscopic surgery is a safe and effective alternative to traditional surgery for managing this complication. We have formulated a simple algorithm that we have found helpful for surgeons considering a laparoscopic approach to managing this condition.     

A new,bioactive, antibacterial‐eluting,composite graft for infection‐free wound healing

The current work focuses on the in vivo performance of a newly developed injectable composite graft in infected full‐thickness wounds. The composite graft was composed of bioactive porous Poly dl‐lactide‐co‐glycolide scaffolds, antibiotic gentamicin, and crosslinked gelatin as carrier gel. Treated infected wounds exhibited a faster wound closure, rapid weight gain, lower neutrophil count, higher breaking strength, and 100 times lesser microbial count (10² colony forming units/g in infected treated vs. 10⁴ colony forming units/g in infected control group) in comparison with infected control group 28 days post treatment. During healing, collagen production was more in the treated groups at day 7 than controls and thereafter gradually reduced to normal levels. Histology revealed a mature scar tissue formation, fibroblast proliferation, epidermal resurfacing, and collagen deposition in reticular alignment similar to normal healthy skin in treated wounds. Further, the plasma concentration of gentamicin was 35–45 μg/mL during the initial 12 hours and reduced to 1 μg/mL in 24 hours, which indicated safe levels of the antibiotic drug during healing. These results clearly indicate a faster, infection‐free, and safe after treatment with the developed graft.     

Miniarthrotomy assisted percutaneous screw fixation for displaced medial malleolus fractures – A novel technique

Aim

To describe here a technique of miniarthrotomy assisted percutaneous screw insertion for displaced Herscovici type B and C medial malleolar fractures.

Method

Incision was made centred over the superomedial angle of the ankle mortise, about half a cm medial to tibialis anterior. Arthrotomy was done and reduction obtained. Percuntaneously, two 4 mm cancellous cannulated screws were inserted through medial malleolus.

Results and conclusion

This approach allows direct visualization of reduction, removal of entrapped soft tissue and preservation of saphenous vein and nerve.     

Analysis of youtube as a source of information for peripheral neuropathy

Introduction: YouTube is an important resource for patients. No study has evaluated the information on peripheral neuropathy disseminated by YouTube videos. In this study, our aim was to perform a systematic review of information on YouTube regarding peripheral neuropathy. Methods: The Web site ( www.youtube.com ) was searched between September 19 and 21, 2014, for the terms “neuropathy,” “peripheral neuropathy,” “diabetic neuropathy,” “neuropathy causes,” and “neuropathy treatment.” Results: Two hundred videos met the inclusion criteria. Healthcare professionals accounted for almost half of the treatment videos (41 of 92; 44.6%), and most came from chiropractors (18 of 41; 43.9%). Alternative medicine was cited most frequently among the treatment discussions (54 of 145, 37.2%), followed by devices (38 of 145, 26.2%), and pharmacological treatments (23 of 145, 15.9%). Conclusions: Approximately half of the treatment options discussed in the videos were not evidence‐based. Caution should be exercised when YouTube videos are used as a patient resource.

Proximal femoral fractures: Principles of management and review of literature

PurposeThe purpose of this study was to review the principles involved in the management of proximal femoral fractures as reported in the literature. Methods: A medical literature search in the MEDLINE (PubMed) and Cochrane database was undertaken to review strategies and principles in proximal femoral fracture treatment. Randomized control trials and meta analysis were given preference while case reports/small series were rejected. Results and conclusions: Early anatomical reduction and surgical fixation remains the best option to reduce the risk of complications like non-union and avascular necrosis in treating fracture neck femurs. Cancellous screws continue to be the preferred treatment for fixation of neck femur fractures in younger population until the benefit of using sliding hip screws is validated by large multicentric studies. In the geriatric age group, early prosthetic replacement brings down the mortality and morbidity associated with neck femur fractures. Sliding hip screw (DHS) is the best available option for stable inter trochanteric fractures. The use of intramedullary nails e.g. PFN is beneficial in treating inter trochanteric fractures with comminution and loss of lateral buttress. Intramedullary implants have been proven to have increased success rates in subtrochanteric fractures and should be preferred over extramedullary plate fixation systems.     

Transvesical NOTES: Survival Study in Porcine Model

Background and Objectives:

The optimal access route and method for natural orifice transluminal endoscopic surgery (NOTES) has not been established. A transvesical approach, with its low rate of peritoneal contamination, is an effective clean portal of entry, but a safe urinary bladder closure has been a challenge. We developed a new technique for a safe, pure transvesical NOTES approach.

Methods:

Four female piglets were used in the study. With the pigs under anesthesia, a flexible cystoscope (15Fr) was used to make an endoscopic cystotomy; diagnostic peritoneoscopy of the abdominal quadrants was done with biopsies and hemostasis. At the end, a Vicryl loop was pushed to close the bladder incision while the incision edges were pulled inwards. The pigs were euthanized after 2 wk, and necropsies were performed.

Results:

No bowel injury was noted in any of the 4 pigs. Satisfactory bladder closure was done in 2 pigs, while a partial closure was achieved in 1 case. In the postoperative period, the pigs showed no signs of pain or distress, voided normally, and had a good appetite. On necropsy, we noted healed cystotomy incisions, no intraabdominal adhesions, and no adhesions at the site.

Conclusion:

Our new technique for endoscopic cystotomy overcomes previously reported risks for bowel injuries. Using this route gives good spatial orientation and access to all quadrants, including the pelvis. Biopsies with good hemostasis can be easily achieved. Lack of intraperitoneal changes postoperatively indicate that this procedure may be safe for humans.     

Recurrent shoulder dislocations secondary to coracoid process fracture: a case report

Coracoid process fracture is easily missed in recurrent anterior shoulder dislocation. We report one such case in a 48-year-old man. Radiology revealed the Bankart lesion and the Hill-Sachs lesion only; the coracoid process fracture was discovered intra-operatively. The anatomy of the shoulder was restored by fixing the fragment to its scapular remnant with a 4-mm cannulated cancellous screw. The tip and the proximal fragment were reamed before inserting the screw. This fragment was routed with attached short head of biceps and coracobrachialis through the lower one third of the subscapularis, before homing it and fixing it to the proximal coracoid fragment. This extraarticular repair resulted in less stiffness than any intra-articular procedure. At the 2-year follow-up, the patient had had no further shoulder dislocation.     

Survival and quality of life after minimally invasive esophagectomy: a single-surgeon experience

Background

Reports on quality of life (QOL) after minimally invasive esophagectomy (MIE) have been limited. This report compares perioperative outcomes, survival, and QOL after MIEs with open transthoracic esophagectomy (TTE) and open transhiatal esophagectomy (THE).

Methods

After institutional review board approval, retrospective review of a prospectively maintained database identified patients who underwent esophageal resection for esophageal cancer at Creighton University between August 2003 and August 2010. Patients with preoperative stage 4 disease, emergent procedures, laparoscopic transhiatal esophagectomies, or esophagojeujunostomies were excluded from the study. The study patients were categorized as having undergone open TTE, open THE, or MIE. Overall survival (OS) was the interval between diagnosis and death or follow-up assessment. Disease-free survival (DFS) was the interval between surgery and recurrence, death, or follow-up assessment. For the patients who survived at least 1?year after surgery, QOL was assessed using European Organization for Research and Treatment of Cancer (EORTC-QLQ, version 3.0) and esophageal module (EORTC-QLQ OES 18) questionnaires.

Results

The study criteria were satisfied by 104 patients. Lymph node harvest with MIE (median = 20) was similar to that with open TTEs (median = 19) and significantly higher (P?P?Conclusions MIEs offer a safe and viable alternative to open esophagectomies because they reduce the need and volume of intraoperative blood product transfusion and postoperative respiratory complications without compromising oncological clearance, survival, and QOL.
