Retroauricular Hairline Incision for Removal of Upper Neck Masses

THE LARYNGOSCOPE, Issue 12 2005
Jong-Lyel Roh MD
Abstract Background/Objectives: The general population has been increasingly concerned about cosmesis and hopeless about prominent or invisible postoperative scars of the face and neck. The purpose of this study was to evaluate the benefit of a retroauricular hairline incision (RAHI) by comparing it with conventional cervical incision for removal of upper neck masses. Study Design: Prospective clinical study. Methods: Thirty-four patients with upper neck masses were divided into two surgical groups of RAHI (17) and conventional cervical incision (17) matched by age, sex, marital status and size, location, pathology of lesions. The operation time, complications, length of hospital stay, and subjective satisfaction with incision scar checked by visual analogue scale were compared between groups. Results: The lesions of each group were congenital cysts (6), abscesses (2), inflammatory masses (2), and benign (6) or malignant (1) tumors and located in the upper neck. Mean operation time was 51 ± 17 minute in the RAHI group and 41 ± 13 minutes in the controls (P = .064). Mean hospital stay and complication rates were comparable between groups. Mean score of patient's satisfaction was 8.9 ± 0.7 in the RAHI group and 4.5 ± 2.7 in the controls (P < .001). The degree of incision scarring did not differ between groups, but the scars were less visible in the RAHI group because of hiding by the auricle and hair. Conclusions: The postauricular approach leading to a potentially invisible area of operation has a clear cosmetic benefit compared with conventional cervical incision. This will be helpful for patients with surgically indicated upper neck masses who hope for invisible incision scars. [source]

Single-port laparoscopic cholecystectomy: A comparative study in 106 initial cases

ASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 3 2010

Abstract Introduction: Laparoscopic cholecystectomy has been the standard of care for gallbladder diseases since the late 1980s. Many surgeons have rapidly adopted single-port laparoscopic cholecystectomy for gallbladder pathologies. The aim of the present study was to analyze the clinical outcome in initial single-port laparoscopic cholecystectomy. Methods: Data from 106 consecutive single-port laparoscopic cholecystectomies between May 2008 and April 2009 were analyzed retrospectively. We divided the patients into two groups , an early group (group I, n=56) and a late group (group II, n=50) , to compare clinical outcomes. During each procedure, only one longitudinal transumbilical incision, 1.5 to 2.0 cm in length, was made to access the abdominal cavity. A multichannel port system was assembled with existing devices. Standard laparoscopic instruments were used to perform each cholecystectomy. Results: Patient demographics did not differ between the two groups. Of the eight cases that were converted to conventional laparoscopic surgery, seven were part of group I (P=0.063). Mean operation time for single-port laparoscopic cholecystectomy was significantly shorter in group II (58.2 versus 71.6 min, P=0.004). There were two operative complications in group I, which were successfully managed with laparoscopic surgery. There was no statistical difference in occurrence of operative complication and hospital stay between the two groups. Conclusion: Single-port laparoscopic cholecystectomy can be safely performed for various gallbladder lesions in selected cases, and the operation time improved with accumulation of cases. [source]

Laparoscopic treatment of lymphoceles in patients after renal transplantation

CLINICAL TRANSPLANTATION, Issue 6 2001
Hans-Joachim Duepree
Postoperative lymphoceles after renal transplantation appear in up to 18% of patients, followed by individual indisposition, pain or impaired graft function. Therapeutic options are percutaneous drainage, needle aspiration with sclerosing therapy, or internal surgical drainage by conventional or laparoscopic approach. The laparoscopic procedure offers short hospitalisation time and quick postoperative recovery. From 1993 to 1997, 16 patients underwent laparoscopic fenestration of a post-renal transplant lymphocele, and were presented in a retrospective analysis. Three patients have had previous abdominal surgery. Following preoperative ultrasound and CT scan, 16 patients underwent laparoscopic drainage after drainage and staining of the lymphocele with methylene blue. No conversion was necessary. Mean operation time was 42 min, no intraoperative complications were seen. Oral nutrition and immunosuppression were continued on the day of surgery, and patients were discharged between the 2nd and 5th (median hospital stay 3.3 d) day after surgery. No recurrence was evident in a follow-up time of 15,54 months (median 31.4 months). Renal function remained unchanged in all patients postoperatively. [source]

Laparoscopic radical prostatectomy: Transfer validity

INTERNATIONAL JOURNAL OF UROLOGY, Issue 5 2010

Objectives: The impact of a formal fellowship training program on the independent practice of the trainees (i.e. transfer validity) has not been evaluated. We analyzed the transfer validity of a structured curriculum in an in-door as well as an out-door setting. Methods: After completing their training, two fourth generation laparoscopic surgeons who started at the same time compared operative parameters and oncological outcomes in their independent practice, prospectively analyzing the next 100 patients in each. One surgeon continued laparoscopic radical prostatectomy (LRP) in the same center of excellence (Group-In), whereas the other implemented the procedure in a separate academic center (Group-Out). Results: The demographics for both groups (Group-In vs Group-Out) were similar regarding age, prostate volume and preoperative prostate-specific antigen levels. Mean operation times (214.8 vs 224.2 min; P = 0.494) and estimated blood loss (472.4 vs 402.6 mL; P = 0.109) did not differ significantly in both groups as well as complication rate (20 vs 24%), median catheter time (8 vs 8.5 days) and continence rates at 12 months (95 vs 95.5%). According to the pathological stages, the rates of positive surgical margins were similar for pT2 (3.2 vs 4.3%) and pT3 (42.8 vs 45.2%), respectively. Conclusions: With a well designed, long-term preclinical and clinical fellowship training program, LRP techniques can be efficiently transferred from the center of excellence to other centers with no significant impact on surgical, functional and oncological outcomes.

PREPERITONEAL GROIN HERNIA REPAIR WITH KUGEL PATCH THROUGH AN ANTERIOR APPROACH

ANZ JOURNAL OF SURGERY, Issue 10 2008

Kugel hernia repair is classically carried out through the posterior approach; in this study we investigated the effectiveness and invasiveness of a Modified Kugel (Bard-Davol Inc., RI, USA) hernia repair procedure carried out through an anterior approach. A prospective series covering a 2-year period, including 122 patients (142 hernias) were carried out using the anterior approach. Patient comfort, complications and recurrence were evaluated. A total of 142 inguinal hernias were repaired, median age was 67 years, the mean operation time was 51 ± 23 min and the average incision was 4.5 cm. There was one case recurrence 5 months after repair. Other complications were few and not severe, only slight groin discomfort was observed in two patients during follow up. This Modified Kugel hernia through anterior approach is effective, mini-invasive and easy to learn with fewer complications. [source]
