Techniques for liver parenchymal transection: a meta-analysis of randomized controlled trials

HPB, Issue 4 2009
Viniyendra Pamecha
Abstract Background:, Different techniques of liver parenchymal transection have been described, including the finger fracture, sharp dissection, clamp,crush methods and, more recently, the Cavitron ultrasonic surgical aspirator (CUSA), the hydrojet and the radiofrequency dissection sealer (RFDS). This review assesses the benefits and risks associated with the various techniques. Methods:, Randomized clinical trials were identified from the Cochrane Library Trials Register, MEDLINE, EMBASE, Science Citation Index Expanded and reference lists. Odds ratio (ORs), mean difference (MDs) and standardized mean differences (SMDs) were calculated with 95% confidence intervals based on intention-to-treat analysis or available-case analysis. Results:, We identified seven trials including a total of 556 patients. Blood transfusion requirements were lower with the clamp,crush technique than with the CUSA or hydrojet. The clamp,crush technique was quicker than the CUSA, hydrojet or RFDS. Infective complications and transection blood loss were greater with the RFDS than with the clamp,crush method. There was no significant difference between techniques in mortality, morbidity, liver dysfunction or intensive therapy unit and hospital stay. Conclusions:, The clamp,crush technique is more rapid and is associated with lower rates of blood loss and otherwise similar outcomes when compared with other methods of parenchymal transection. It represents the reference standard against which new methods may be compared. [source]

Difficult laparoscopic cholecystectomy in acute cholecystitis: use of ,finger port', a new approach

HPB, Issue 3 2003
R Sinha
Background Adhesions in acute cholecystitis tax even the more experienced operator during laparoscopic cholecystectomy. Blunt and sharp dissection, electrocautery, laser, hydrodissection, and ultrasonic dissection may all have their limitations. Thus there is a need for an alternative and more effective method. Method Laparoscopic cholecystectomy was carried out in 281 patients with acute cholecystitis. Separation of the gallbladder from the adherent structures was carried out in 13 patients, using the forefinger of the left hand introduced through the right hypochondrial port. In two patients a second finger was introduced through the epigastric port. Results The mean time required for the dissection was 7.9 minutes. Finger dissection failed in three patients because of dense adhesions on a high subcostal position of the gallbladder. Discussion Finger dissection is easy, fast, and limits injury because of the direct vision and tactile sensation, which are missing in other methods of laparoscopic dissection. [source]

Endoscopic Treatment of Salivary Gland Injuries due to Facial Rejuvenation Procedures

THE LARYNGOSCOPE, Issue 5 2008
Oded Nahlieli DMD
Abstract Objective: The purpose of this article is to describe innovative surgical techniques for treatment of salivary gland injuries caused by facial rejuvenation procedures. Methods: Between 2001 and 2007, a total of 14 patients, all females ages 46 to 70 who suffered from salivary gland injuries caused by facial rejuvenation procedures, were treated, primarily by an endoscopic-guided technique that involved location of the injury and endoscopic repair. Results: There were four types of postsurgical injuries of the salivary glands that were caused by operations for facial rejuvenation: 1) compression of salivary ducts with temporary swelling (n = 1); 2) laceration of the capsule of the salivary gland (n = 3); 3) stretching and compression of the ducts with penetration of the capsule of the duct leading to sialocele and long-term swelling (types 1 and 2 combined) (n = 5); and 4) complete cut or penetration of the main salivary duct or of one of its main branches resulting in sialocele (n = 5). The endoscopic technique treatment was successful in all cases. Conclusion: The main reasons for salivary gland injuries due to facial rejuvenation procedures in our patients were: poor anatomical identification of the border between the superficial muscular aponeurotic system (SMAS) and the parotid capsule; penetration of the salivary gland capsule by blunt or sharp dissection; unnecessary use of sharp-tip scissors; and a tear of the salivary duct by hooks during a face-lift procedure. Plastic surgeons should be aware of these complications and try to improve their techniques accordingly. To avoid atrophy of the salivary gland, once the diagnosis it made, it is advisable to send the patient to a maxillofacial or ENT surgeon skilled in endoscopy. [source]

Endoscopic Management of Extruding Medialization Laryngoplasty Implants

THE LARYNGOSCOPE, Issue 6 2005
Stacey L. Halum MD
Abstract Background: Medialization laryngoplasty (ML) is a commonly performed procedure for vocal fold motion impairment with glottic incompetence. Although implant extrusion is a well-known risk of ML, management of this complication is rarely mentioned in the literature. The aim of this study was to review our experience with endoscopic implant retrieval for a group of patients with extruding ML implants. Methods: All patients identified in our institution from January 1989 through August 2004 with a history of ML and extruded implants were identified. Case management was reviewed, including information on presentation, management techniques, and outcomes. Results: Five patients presented with extruding ML (Gore-Tex [n = 2] or silastic [n = 3]) implants. All patients presented with worsening dysphonia and evidence of fullness and/or granulation tissue at the extrusion site. Endoscopic removal was performed using either sharp dissection or CO2 laser dissection. After removal, four patients underwent vocal fold injection augmentation. Conclusions: Endoscopic removal appears to be a safe, effective, and even preferred alternative to external transcervical removal in selected cases of extruding implants. [source]

Local recurrence following surgical treatment for carcinoma of the lower rectum

ANZ JOURNAL OF SURGERY, Issue 9 2004
Adrian L. Polglase
Background: The present paper examines the local recurrence rate following surgical treatment for carcinoma of the lower rectum with principally blunt dissection directed at tumour-specific mesorectal excision (including total mesorectal excision when appropriate). Methods: During the period April 1987,December 1999, 123 consecutive resections for carcinoma of the middle and distal thirds of the rectum were performed. The patients had low anterior resection, ultra low anterior resection or abdomino-perineal resection. Ninety-six eligible patients underwent curative resection. The mean follow-up period was 66.8 months ±44.3 (range 3,176 months). Data were available on all patients having been prospectively registered and retrospectively collated and computer coded. Results: The overall rate of local recurrence was 5.2% (four recurrences following ultra low anterior resection and one following abdomino-perineal resection. No local recurrence occurred after low anterior resections.). Local recurrences occurred between 16 and 52 months from the time of resection, and the cumulative risk of developing local recurrence at 5 years for all patients was 7.6%. The overall 5-year cancer specific survival of the 96 patients was 80.8%, and the overall probability of being disease free at 5 years, including both local and distal recurrence, was 71.8%. Conclusion: The results of the present series confirm the safety of careful blunt techniques combined with sharp dissection for rectal mobilization along fascial planes resulting in extraction of an oncologic package with tumour-specific mesorectal excision (or total mesorectal excision when appropriate).
