Future perspectives and research initiatives in fast-track surgery

Background and aims Major surgery is still followed by a risk of morbidity, a need for hospitalisation and convalescence. Fast-track surgery has been introduced as a coordinated effort to combine unimodal evidence-based principles of care into a multi-modal effort to enhance recovery. The aim of this article was to update recent data on fast-track abdominal surgery and outline future strategies for research.Results The data from fast-track colonic resection support the validity of the concept because pain, ileus, cardiopulmonary function and muscle function were all improved, compared with traditional treatment and with reduced post-operative fatigue and convalescence. Although less data is available, similar positive results may be achieved in other types of major surgery. Current research initiatives include improved multi-modal non-opioid analgesia, rational principles for perioperative fluid management, pharmacological reduction of surgical stress responses and the role of laparoscopic procedures within the fast-track concept.Conclusions Fast-track surgery has evolved as a valid concept to improve post-operative outcome. Further progress may be expected based upon intensified research within perioperative pathophysiology and a multi-disciplinary collaboration between surgeons, anaesthesiologists and surgical nurses.     

成人腰椎峡部裂型滑脱症的微创治疗

Objective To investigate the clinical experiences and technical skills of adult isthmic spondylolisthesis. Methods Twenty-one patients with adult isthmic spondylolisthesis underwent minimally invasive surgery. There were 12 men and 9 women, with the mean age of 51.7 years. Isthmic spondylolisthe-sis occurred at the L4.5 in 7 patients, and at the L5S1 in 14 patients. According to Meyerding classification, 13 cases were of Grade Ⅰ, 7 of Grade Ⅱ, 1 of Grade Ⅲ. Under general anesthesia, guiding by fluoroscopy, the surgeries performed minimally invasive microendoscopic(METRx) techniques for posterior decompression, interbody cage fusion and novel Sextant-R percutaneous pedicle screw techniques for deformity reduction and fixation. Results Seventeen cases were followed up 1 year postoperatively. The average low back pain VAS reduced from preoperative 6.0±2.6 to postoperative 2.9±2.5. The average leg pain VAS decreased from preoperative 6.7±3.3 to postoperative 2.8±1.6. The average ODI decreased from preoperative 44.3% to post-operative 27.1%. The Nakai good and excellent rate was 90%. The mean operative time 170 min, blood loss 160 ml, and postoperative stay in bed 7.5 d. The sagittal spondylolisthesis rate significantly decreased from preoperative 35.5%±2.5% to postoperative 8.3%±7.5%. The lordotic angle from preoperative 11.5°±1.7° in-creased to postoperative 16.8°±9.5°; the intervertebral disc height from preoperative (5.4±2.5) mm increased to postoperative (9.1±3.0) mm. According to Lenke judgement for fusion, complete fusion rate was 76%, in-complete fusion rate was 12%, nonfusion rate was 12%. Conclusion The minimally invasive microendo-scopic (METRx) assisted with a novel Sextant-R percutaneous pedicle screw systems for deformity reduction and fixation to treat adult isthmic spondylolisthesis, is not only a minimally invasive and safe surgical tech-nique, also an effective treatment for deformity reduction and fixation.     

Free flap monitoring with continuous tissue oxygen tension measurement

Intraoperative and postoperative free flap monitoring by means of oxygen tension measurement was carried out in 11 patients. We used an invasive flexible microcatheter that allowed for measurement of oxygen tension in all types of free flaps. Two cases of the measured flaps were buried free flaps which do not allow monitoring by clinical assessment. All flaps monitored in this study survived. One case of displacement of the microcatheter occurred. In one patient, the tissue pO₂ monitor successfully detected early vascular thrombosis with subsequent reoperation and salvage of the free flap.

目的探讨溃疡性结肠炎的外科治疗方式。方法对16例行外科手术治疗的溃疡性结肠炎的临床资料进行回顾性分析。结果本组16例行外科手术治疗，占全部收治患者的20．5％（16／78）。手术原因包括保守治疗无效10例，肠梗阻3例，合并息肉可疑癌变3例。行全结直肠切除、回肠造口术8例，全结直肠全切除、回肠肛管吻合术4例，结肠全切除、回直肠吻合术2例，结肠部分切除2例。结论溃疡性结肠炎主要手术指征为内科治疗无效或合并肠梗阻及并发息肉可疑癌变者。全结肠切除、回肠造口术治疗较彻底，全结直肠切除、回肠贮袋肛管吻合术可改善排便控制功能，但吻合口溃疡发生率高。     

乳腺癌乳房部分切除术后即刻背阔肌肌皮瓣重建乳房的临床应用

Objective To study the immediate conservative breast surgical reconstruction by trans-ferring the same lateral latissimus dorsal myocutaneous flap (LDM) for the treatment of stage Ⅱ and stage Ⅲ breast cancer, combined with neoadjuvant chemotherapy. Methods Breast cancer patients in stage Ⅱ and Ⅲ with pathological diagnosis by core needle biopsy, had undergone immediate conservative breast reconstruction surgery with transferring the latissimus dorsal myocutaneous (LDM). We scored the reconstructed breast twice at one month after operation and completion of radiation. The final score was decided using the mean value of the twice evaluating score. Kaplan-Meier survival was used to analyze the survival of 18 cases with traditional mastectomy. Results The tumor size ranged from 30 mm to 55 mm before neoadjuvant chemotherapy, and ranged from 25mm to 45 mm after neoadjuvant chemotherapy. The median weight of the tumor specimens in breast conservative operation was 140 g (90 g to 220 g). A-mong the 18 patients, 16 cases had more than 3 scores with satisfied cosmetics (93.33 % ). Dorsal subcu-taneous seroma in donation area was observed in 5 of 18 patients (27.78 %) and dorsal incision dehiscence was observed in 2 of 18 patients (11.11%). None of the patients developed recurrence except that 1 pa-tient (5.55 %) had distance metastasis (bone metastasis} in a mean 22-months follow-up. The Kaplan-Meier survival curve in breast conservation reconstruction patients had no different from that of traditional mastectomy patients at the same time. Conclusions Immediate conservative breast surgical reconstruction by using the same lateral latissimus dorsal myocutaneous flap is an effective method for stage Ⅱ and stage Ⅲ breast cancer patients combined with neoadjuvant chemotherapy, which can increase satisfactory breast so that cosmetic outcome can be reached.     

Pedicled deltoid hatchet flap for treatment of pressure sore at the shoulder

Whereas decubitus ulcer in the back or hip region is a common entity in plegic or elderly patients, the occurrence in the lateral shoulder region is seldom seen. However, resulting from continuous lateral decubitus positioning or limited compliance by the patient, pressure sores may occur in almost any region of the body, but predominately, they arise in acral zones with underlying bone prominences. The deltoid area is such an anatomically critical region, especially if the underlying deltoid muscle is paralyzed. The transposition of a pedicled deltoid flap, slightly modified as a hatchet flap, is described for cover of a decubitus ulcer in the deltoid region in a paraplegic male. Although utilization of the deltoid flap as a free flap is an established procedure for selected indications [Russell et al. (1985) Extremity reconstruction using the free deltoid flap. Plast Reconstr Surg 76:586–595, Serafin D (1996) The deltoid flap. In: Serafin D (ed) Atlas of microsurgical composite tissue transplantation, chapter 19. Saunders, Philadelphia, PA, pp 153–159, Wang et al. (2003) The free deltoid flap: microscopic anatomy studies and clinical application to oral cavity reconstruction. Plast Reconstr Surg 112:404–411], transposition as a pedicled flap, to the best of our knowledge, has not been previously described in the available literature.
