Ever since the beginning of laparoscopic Cholecystectomy, in 1985 by Erich Mühe in Germany followed by Harry Reich and Eddie Joe Reddick an American in 1989, the technique has seen many areas of refinements. Initially popularized techniques were turned down by the pioneers on the account of incredible and awful complications substantiated by controlled trials. The dissection of the cystic pedic...

OBJECTIVE Many studies have been conducted to investigate the efficacy of harmonic scalpels in thyroidectomies. Here, we present our clinical experiences with the instrument. MATERIALS AND METHODS The study was conducted at the General Surgery Department of the Ataturk University School of Medicine between January 2005 and July 2008. It was a prospective, randomized, controlled study. Patient...

Objective: To estimate the frequency of gallbladder perforation with conventional Monopolar Diathermy versus Harmonic scalpel in laparoscopic cholecystectomy.
 Study Design: Quasi-experimental study.
 Place and Duration Study: Department Surgery, Combined Military Hospital, Quetta Pakistan, from Sep 2018 to 2019.
 Methodology: A total 160 patients undergoing cholecystectomy for s...

conclusions hs in total thyroidectomy, reduces operating time, blood loss, postoperative pain, drainage volume, voice changes, and postoperative hypocalcemia, compared to conventional techniques. background traditional haemostatic techniques in total thyroidectomy may cause some damages to surrounding tissues. it is believed that these damages can be reduced using ultrasonic dissector devices l...

Design: A systematic search for randomized controlled trials comparing total tonsillectomies performed using vessel sealing systems (VSS), Harmonic Scalpel (HS), or radiofrequency ablation (ie, Coblation) with the conventional technique of cold steel and/or electrocautery dissection (CS/EC). Estimation of odds ratios and 95% confidence intervals (CIs), weighted mean differences (WMD), or standa...

Partial defect of the pericardium combined with bronchogenic cyst is a very rare congenital anomaly. We describe the case of a 32-year-old man with a partial defect of the left pericardium and a bronchogenic cyst arising from the border of the pericardial defect. The cyst was successfully resected with the harmonic scalpel by three-port videothoracoscopic approach.

We present an unusual complication of a ureteral injury occurring during a bilateral laparoscopic salpingo-oophorectomy with the Harmonic scalpel (HS). The case illustrates in the same patient the versatility of the HS as a laparoscopic surgical instrument and energy source while at the same time demonstrating the potential for adverse, unexpected complications.
