ABSTRACT
PURPOSE: This study aims to determine the effects of perioperative dexmedetomidine infusion (PDI) on Asian patients undergoing bariatric-metabolic surgery (BMS), focusing on the need for pain medications and management of postoperative nausea and vomiting (PONV), and to investigate the association with these variables, including patients' characteristics and BMS data. MATERIALS AND METHODS: A retrospective review of prospectively collected data was conducted in an Asian weight management center from August 2016 to October 2021. A total of 147 native patients with severe obesity were enrolled. All patients were informed of the full support of perioperative pain medications for BMS. The pain numeric rating scale scores, events of PONV, needs for pain medications, and the associated patients' characteristics were analyzed. A p-value of < 0.05 was considered statistically significant. Furthermore, to verify the effects of perioperative usage of dexmedetomidine for BMS, a systematic review with meta-analysis of currently available randomized control trials was performed. RESULTS: Among the 147 enrolled patients, 107 underwent laparoscopic sleeve gastrectomy and 40 underwent laparoscopic Roux-en-Y gastric bypass. PDI has been used as an adjunct multimodal analgesia for BMS in our institution since June 2017 (group D; n = 114). In comparison with those not administered with perioperative dexmedetomidine (group C; n = 33), lower pain numeric rating scale scores (2.52 ± 2.46 vs. 4.27 ± 2.95, p = 0.007) in the postanesthesia care unit, fewer PONV (32.46% vs. 51.52%; p = 0.046), and infrequent needs of additional pain medications (19.47% vs. 45.45%; p = 0.003) were observed in group D. Multivariable analysis demonstrated that type II diabetes mellitus was correlated with the decreased need of pain medications other than PDI (p = 0.035). Moreover, dexmedetomidine seemed to have a better analgesic effect for patients with longer surgical time based on our meta-analysis. CONCLUSION: Based on our limited experience, PDI could be a practical solution to alleviate pain and PONV in Asian patients undergoing BMS. Moreover, it might reduce the need for rescue painkillers with better postoperative pain management for patients with type II diabetes mellitus or longer surgical time.

OBJECTIVES: Postoperative recurrent primary spontaneous pneumothorax (PSP) is a troublesome complication and an important issue to be discussed. This study is to determine whether Re-video assisted thoracoscopic surgery (VATS) should be performed for postoperative recurrent PSP (PORP). MATERIALS AND METHODS: Patients who had underwent needlescopic VATS for PSP between Jan. 2007 and Dec. 2011 were reviewed. RESULTS: VATS was initially performed on 239 patients with PSP in total. Eleven patients were found to have PORP during a follow-up period of 36.95 months. Nine patients received Re-VATS and only two patients receiving conservative treatment had no further recurrence. No conversion to thoracotomy, blood transfusion and prolong air leak were recorded. CONCLUSIONS: Even for smaller size cases, Re-VATS, which is technically feasible, safe and effective with better cosmetics and minor postoperative pain, should be a strong contender as priority treatment.
ABSTRACT
Minimally invasive surgery is the current trend of approach in various fields. Since May 2006, our team has started implementing needlescopic video-assisted thoracic surgery as the standard surgical treatment for primary spontaneous pneumothorax. During a seventeen-month period, 62 consecutive patients with primary spontaneous pneumothorax were operated on. The ages, sex ratio, operative times, blood loss, postoperative pain in visual analog scale (VAS), length of stay and hospital costs were recorded and compared with that of another 62 consecutive patients who received conventional video-assisted thoracic surgery between July 2004 and April 2006. Only the postoperative pain in VAS was significantly lower in the needlescopic video-assisted thoracic surgery group; the rest remained the same. Also the wounds were almost undetectable in the needlescopic video-assisted thoracic surgery patients. There were no major complications, mortality or recurrence in either group. Needlescopic video-assisted thoracic surgery is a high-tech technique which provides safety, effectiveness, economy and outcome comparable to that of conventional techniques. It is also associated with less pain and better cosmetics.
