Comparison between Focus Harmonic scalpel and other hemostatic techniques in open thyroidectomy: A systematic review and meta-analysis.

BACKGROUND: The purpose of this review was to compare the efficacy and surgical outcomes of total thyroidectomy between the Focus Harmonic scalpel (Ethicon, Cincinnati, OH) and other hemostatic procedures. METHODS: An extensive search was conducted using the PubMed and Cochrane databases from January 2008 to October 2014. Operating time, blood loss, pain, complications, and hospital stay were evaluated. RESULTS: When compared with conventional techniques or LigaSure Precise Vessel Sealing System (Medtronic, Minneapolis, MN), the use of the Focus Harmonic scalpel reduced operative time by 22,428 minutes and blood loss by 13,914 mL. Length of hospital stay was significantly shorter in the Focus Harmonic scalpel group with a mean reduction of 0.410 days. CONCLUSION: According to our meta-analysis, when comparing the Focus Harmonic scalpel versus conventional techniques, it seems evident that the use of this device in thyroid surgery is associated with a mean reduction in operating time, blood loss, and hospital stay, without any increase in pain and complications. There was no appreciable difference between the Focus Harmonic scalpel and the LigaSure Precise Vessel Sealing System. © 2016 Wiley Periodicals, Inc. Head Neck 38: First-1578, 2016.

The use of FOCUS Harmonic scalpel compared to conventional haemostasis (knot and tie ligation) for thyroid surgery: a prospective randomized study.

Haemostasis is crucial in thyroid surgery to avoid intraoperative and postoperative complications. In the present study, we evaluated the efficiency and the safety of Harmonic scalpel when compared to conventional suture ligation in open total thyroidectomy. We enrolled 265 patients who underwent total thyroidectomy for multinodular disease since October 2011 up to October 2013. They were randomized into two groups: 141 in group HS (Harmonic Scalpel), 124 in group CT (Conventional tecnique). We recorded the following data: operative time, post-operative blood loss, length of hospital stay and complications. The patients were monitored for 48 hours after surgery. Several differences were observed between the two groups (HS vs CT): the use of Harmonic scalpel was associated to a significant reduction of surgical operative time (110 min in CT vs 79.36 min in HS, p = 0.00001) and also associated to a lower blood loss (97.38 ml in CT vs 68.72 ml in HS, p = 0.00001). The length of stay was significantly shorter in the HS group (2.75 days in CT vs 1.93 days in HS) Complication rate was similar in the two groups. According to our experience, the Harmonic scalpel represents a safe alternative to conventional haemostasis in thyroid surgery, allowing for a significant reduction of operative time, blood loss and hospitalization. The rate of complication demonstrated no significant difference among the two groups.

Managing the incidentally detected gallbladder cancer: algorithms and controversies.

INTRODUCTION: Gallbladder cancer (GBC) is the fifth most common neoplasm of the gastrointestinal tract and the most common cancer of the biliary tract. GBC is suspected preoperatively in only 30-40% of patients. The other 60-70% are discovered incidentally (IGBC) by the pathologist on a gallbladder specimen following cholecystectomy for benign diseases such as polyps, gallstones, and cholecystitis. MATERIALS AND METHODS: Between 1995 and 2011, 30 cases of GBC, who underwent resection with curative intent in our institutions, were retrospectively reviewed. They were analyzed for demographic data, and type of operation, surgical morbidity and mortality, histopathological classification, and survival. Incidental GBC was compared with suspected or preoperatively diagnosed GBC. Overall survival, disease-free survival (DFS) and the difference in DFS between patients previously treated with laparoscopic cholecystectomy and those who had oncological resection as first intervention were analyzed. The authors also present a systematic review to evaluate the role of extended surgery in the treatment of the incidental GBC. RESULTS: GBC was diagnosed in 30 patients, 16 women and 14 men. The M/F ratio was 1:1.14 and the mean age was 69.4 years (range 45-83 years). A preoperative diagnosis was possible only in 14 cases; fourteen of the incidental cases were diagnosed postoperatively after the pathological examination; two were suspected intraoperatively at the opening of the surgical specimen and then confirmed by frozen sections. The ratio between incidental and nonincidental cases was 1, 14/1, with twelve cases discovered after laparoscopic cholecystectomy. Eighty-one per cent of the incidental cases were discovered at an early stage (≤II). The preoperative diagnosis of the 30 patients with GBC was: GBC with liver invasion diagnosed by preoperative CT (nine cases); gallbladder abscess perforated into hepatic parenchyma and involving the transversal mesocolon and hepatic hilum (one case); porcelain gallbladder (three cases); gallbladder adenoma (four cases); and chronic cholecystolithiasis (thirteen cases). Every case, except one, with a T1b or more advanced invasion underwent IVb + V wedge liver resection and pericholedochic/hepatoduodenal lymphoadenectomy. One patient refused further surgery. Cases with Tis and T1a involvement were treated with cholecystectomy alone. Nine of the sixteen patients with incidental diagnosis reached 5-year DFS (56.25%) and eight of them are recurrence free. Surprisingly, one patient reached 38 mo survival despite a port-site recurrence (the only one in our experience) 2 years after the original surgery requiring further resection. Cases with non incidental diagnosis were more locally advanced and only two patients experienced 5 years DFS (Tables 2 and 3). CONCLUSION: Laparoscopic cholecystectomy does not affect survival if implemented properly. Reoperation should have two objectives: R0 resection and clearance of the lymph nodes.

Incisional hernia in the elderly: risk factors and clinical considerations.

OBJECTIVE: Ventral incisional hernia is a common complication of abdominal surgery. The marked improvements in medical technology and healthcare, lead to an increasing number of elderly patients to take advantage of even complex surgical procedures. The objective of this literature review was to analyze the risk factors for ventral incisional hernia in elderly patients and to identify measures that might decrease the incidence of this complication. MATERIALS AND METHODS: An analysis of the surgical literature was performed using the search engines EMBASE, Cochrane Library, and PubMed with particular reference to elderly patients using the keywords: abdominal hernia, wound dehiscence, incisional hernia, incidence, trocar site hernia, and hernia prevention. RESULTS: In our opinion the risk factors for incisional hernia should be separately considered. First those related to the patients and to the abdominal surgery and, in addition, those related to the surgery of the abdominal wall defects. CONCLUSIONS: Reparative surgery of the abdominal wall, to date uniquely characterized by the use of the mesh, should be considered an additional risk factor for the occurrence of incisional hernia. However, the low incarceration risk, the risk of recurrence, the relevant rate of postoperative pain and discomfort and complications associated with mesh repair, as small bowel obstruction, mesh infection, and entero-cutaneous fistula, suggest that the general indication for surgical treatment of incisional hernias, in a symptomatic or oligosymptomatic elderly patients, should be critically reconsidered in order to avoid unnecessary surgery.

Appendix stump closure with endoloop in laparoscopic appendectomy.

AIM: To address the question of the appendix stump closure in laparoscopic appendectomy and evaluate the incidence of intraoperative and postoperative complications after application of endoloops. MATERIAL OF STUDY: Data included age and gender, ASA score, co-morbid illness, prior abdominal surgery, clinical presentation, operative time, conversion rate and reasons for conversion, postoperative morbidity and mortality rates, pathologic diagnosis, and length of hospital stay. RESULTS: Laparoscopic appendectomy with stump closure using endoloops was performed in 35 consecutive patients. Postoperative complications occurred in three patients. The mean postoperative hospital stay was 2 days. The perioperative mortality rate was 0%. DISCUSSION: The treatment of appendiceal stump closure in laparoscopic appendectomy represents the main technical aspect and it is an important step for its potentially serious postoperative complications due from an inappropriate management. Endostapling, hem-o-lok clips and intracorporeal knotting are the most commonly recommended methods. All alternatives have advantages and disadvantages against the different clinical stages of acute appendicitis, and it should be noted that the different forms of appendiceal stump closure have never been assessed in prospective randomized studies. CONCLUSIONS: From our experience we can confirm that the endoloop can be safely used and should be the preferred modality in treating the appendiceal stump, especially for low-grade appendicitis. Alternative methods should be used in case of phlegmonous or gangrenous appendicitis, perityphlitic abscess or simultaneous operation for Meckel's diverticulum. Knowledge about and appropriate use of all of them are important for a safe and more cost-effective procedure. KEY WORDS: Appendiceal stump closure, Laparoscopic appendectomy.

Can laparoscopic cholecystectomy be safety performed in the elderly?

AIM: To assess the suitability of laparoscopic cholecystectomy in elderly patients, although early reports have questioned the efficacy of this procedure in that patient group. MATERIAL OF STUDY: Retrospective study evaluating the medical records of the elderly patients who underwent laparoscopic cholecystectomy in our surgical unit. Data included age and gender, American Society of Anesthesiologists (ASA) score, comorbid illness, prior abdominal surgery, presentation, operative time, conversion rate, postoperative morbidity, and mortality rates and length of hospital stay. RESULTS: Fifty consecutive patients age 70 or older who underwent laparoscopic cholecystectomy were studied Postoperative complications occurred in five patients. DISCUSSION: Many Studies have shown that the incidence of complicated gallstone disease in the elderly is higher when compared with that of younger patients and gallbladder disease is particularly virulent in the elderly, with high rate of acute cholecystitis, biliary tract disease, increased morbidity, and prolonged hospital stay. This poor outcome has been attributed to the presence of severe co-morbid factors associated with the aging process. Compared to open cholecystectomy, laparoscopic cholecystectomy may cause less postoperative depression of respiratory function and cell-mediated immunity. In our study perioperative mortality rate was 0%. CONCLUSIONS: Laparoscopic cholecystectomy in elderly patients is a relatively safe procedure that can be accomplished with acceptable low morbidity. In this series of geriatric patients, there was no evidence of any increased risk for conversion to an open cholecystectomy, delayed recovery, or prolonged hospitalization.
