Laparoscopic Partial Adrenalectomy: Surgical Technique and Outcome
고오석,김지용,김형진,정영범 대한비뇨기종양학회 2019 대한비뇨기종양학회지 Vol.17 No.2
Purpose: To examine the perioperative surgical and long-term outcomes of laparoscopic partial adrenalectomy (LPA) by comparing the results of laparoscopic total adrenalectomy (LTA) Materials and Methods: A total of 132 transperitoneal laparoscopic adrenalectomies were performed for adrenal gland tumor between May 2006 and April 2019. All surgeries were performed by a single surgeon. Seventy patients underwent LTAs and 54 underwent LPAs. The data were collected retrospectively through review of the medical charts. We compared the perioperative and long-term outcomes between the 2 surgical methods. Results: A total of 70 patients, including 4 patients with bilateral tumors, underwent LTA. In contrast, 54 patients, including 4 patients with bilateral masses, underwent LPA. There were no differences between the 2 groups with regard to mean age at presentation, mean tumor size, or postoperative stay. However, the mean operating time was significantly shorter in the LPA group than that of the LTA group. The mean estimated blood loss in the LPA group was significantly higher than that in the LTA group. However, none of the LPA patients required blood transfusion. The biochemical markers and laboratory values normalized postoperatively in all patients with functional adrenal tumors. There was no local recurrence during the follow-up period. Conclusions: Our data demonstrate that the surgical outcomes and perioperative complications in LPA group are similar to those of LTA. When LPA is performed for small adrenal lesions, most patients remain steroid independent, as well as recurrence-free at long-term follow-up.

Purpose: The transobturator adjustable tape (TOA) sling operation is an effective procedure that allows for correction of postoperative incontinence or obstruction through adjustment of the mesh tension. During the operation, the outer cylinder of a ballpoint pen was used for proper mesh placement with less dissection. We evaluated the efficacy and safety of the TOA sling operation with the use of the outer cylinder of a ballpoint pen. Materials and Methods: A total of 127 consecutive women with stress urinary incontinence underwent the TOA sling operation with the use of the outer cylinder of a ballpoint pen. The preoperative evaluations included a stress cough test, urodynamic study, and questionnaires related to quality of life. The mesh tension was adjusted 1 day after the operation. Postoperative evaluation was done at 1 month and included a stress cough test, uroflowmetry, questionnaires, and asking about satisfaction. At 1 year, we evaluated the patients with a stress cough test and by asking about their satisfaction with the procedure. Results: The overall cure rate was 95.3% at 1 month and 96.8% at the 1-year follow-up. Postoperative adjustment of the mesh tension was done for 22 patients (17.3%). Eight patients needed increased tension for remaining stress urinary incontinence, and 14 patients needed reduced tension for urinary obstruction. The maximal flow rate was decreased significantly. However, the residual urine volume was not increased significantly. The total score on the questionnaires increased significantly. Conclusions: Results were excellent compared with outcomes of the traditional TOA sling procedure. Proper mesh placement by use of the outer cylinder of a ballpoint pen with less dissection and tension adjustment could improve the success rate of the TOA sling operation.

허당,전준민,서성규,고오석,서병량,윤형선 한국냄새환경학회 2006 실내환경 및 냄새 학회지 Vol.5 No.1
This study estimated the emission characteristics of odorous volatiles organic compounds (VOCs) from major 7 emission facilities by industrial classification in Yeosu petrochemical industrial complex. This study investigated terminal emission facilities (Inlet and outlet) in the industrial plant area, the plant boundary area and Samil-dong which has many civil appeal for an offensive odor to grasp VOCs concentration in ambient air of the plant boundary area and civil appeal area from May, 2002 to December, 2004, besides. VOCs were sampled 6 L using silicocan canisters and toluene, xylene and styrene which are known as odorous VOCs were analyzed by cryogenic preconcentration system and GC/MS. The removal efficiency of emission facilities in the industrial plant area for odor showed 96.5% of wet scrubber, 89.5% of RTO and 86.0% of RCO. The concentration of odorous VOCs at the plant limits area in 2003 were higher than 2002. The reason was guessed that toluene of high concentration emitted from terminal emission facilities in the industrial plant area influenced on ambient air at the plant boundary area. The concentration of odorous VOCs in ambient air at Samil-dong were decreasing from 1995 to 2001, but the concentration of toluene sharply increased from 2002. The reason was presumed that VOCs emission increased due to expansion of Yeosu petrochemical industrial complex and removal efficiency of terminal emission facilities dropped due to outworn equipments for VOCs prevent.
