Short and long term outcomes of laparoscopic fenestrating or reconstituting subtotal cholecystectomy versus laparoscopic total cholecystectomy in the management of acute cholecystitis.

BACKGROUND: Strasberg proposed classifying subtotal cholecystectomy techniques into fenestrating (fSC) and reconstituting (rSC) subtypes. The aim of this study is to compare our outcomes of laparoscopic subtotal cholecystectomies of both subtypes against laparoscopic total cholecystectomy (TC) in difficult emergency laparoscopic cholecystectomies. METHODS: Patients undergoing emergency laparoscopic cholecystectomy were identified over 2 years and all Nassar scale 3 and 4 cholecystectomies were included for analysis. RESULTS: 108 fSC and 24 rSC were compared against 317 TC. Patients undergoing fSC and rSC were older and more likely to be male. fSC (128 min) and rSC (141 min) recorded longer median operative times than TC (109). Post-operative ERCP was more common after rSC (16.7%). Patients undergoing fSC (2 days) and rSC (3.5 days) had longer post-operative stays. Bile leaks were more likely in fSC (9.3%) and rSC (8.3%) compared to TC (1.9%), Long term morbidity was higher in the rSC group (12.5% vs 10%). And these were solely due to gallbladder remnant complications. CONCLUSION: Laparoscopic fSC and rSC techniques are associated with a higher rate of bile leaks and rSC has more long term morbidty as compared to TC.

Combined Vascular and Orthopaedic Approach for a Pseudotumor Causing Deep Vein Thrombosis after Metal-on-Metal Hip Resurfacing Arthroplasty.

Introduction. Metal-on-metal (MoM) hip resurfacings have been associated with a variety of complications resulting from adverse reaction to metal debris. Pseudotumors have rarely been reported to cause deep venous thrombosis (DVT). Study Design. A case report and a review of the literature. Case Presentation. A 75-year-old female who had left metal-on-metal hip resurfacing 6 years ago presented with left groin pain associated with unilateral lower limb edema and swelling. By duplex and MRI studies, our patient had an extensive soft tissue necrosis associated with a large pelvic mass causing extensive DVT of the lower limb secondary to mechanical compression of the left iliac vein. Results. Our case was initially treated for DVT followed by dual surgical approach. The pseudotumor was excised through a separate iliofemoral approach and revision of the hip implant was undertaken through a posterior approach in the same setting. An inferior vena cava (IVC) filter was inserted to minimise the perioperative risks of handling the iliac veins. Conclusion. A combined approach with vascular surgeons is required. Combined resection of the pseudotumor and revision of the metal bearing surfaces is essential, in order to achieve a good surgical outcome in this rare complication.

Evidence-based assessment: evaluation of the formocresol versus ferric sulfate primary molar pulpotomy.

PURPOSE: Formocresol and ferric sulfate were evaluated as pulpotomy medicaments using evidence-based dentistry principles. Formocresol has been challenged as a potential carcinogen and mutagen, leading to consideration of ferric sulfate. METHODS: The PICOT statement was: (P) In human carious primary molars with reversible coronal pulpitis, (I) does a pulpotomy performed with ferric sulfate, (C) compared with formocresol, (O) result in dinical/radiographic success, (T) in time periods up to exfoliation? Relevant papers (N=894) were identified from databases and inclusion criteria were applied; 94 papers remained (randomized clinical trials [RCTs]=7; clinical trials [CTs]=28; case-control studies=14; opinions, cohort, and cross-sectional studies=4; reviews=22; irretrievable papers=19). Three RCTs and 10 CTs (total teeth: formocresol=753; ferric sulfate=90) were meta-analyzed; 1 RCT and 1 CT were tested for homogeneity (odds ratios; 95% confidence intervals); 3 RCTs and 10 CTs were examined by student's t test. RESULTS: Clinical data indicated ferric sulfate was significantly more successful than formocresol (OR=1.95; CI=1.01-3.80). Radiographic data indicated no difference between medicaments (OR=0.90; CI=0.58-1.39). Medicaments did not differ with t-tests of clinical (P>.10) and radiographic (P>.50) data. CONCLUSIONS: This evidence-based assessment concluded that, in human carious primary molars with reversible coronal pulpitis, pulpotomies performed with either formocresol or ferric sulfate are likely to have similar clinical/radiographic success.
