Duration of postlaparoscopic pneumoperitoneum

Background: Patients who present with abdominal pain after recent laparoscopic surgery present a diagnostic dilemma when pneumoperitoneum is present. Previous studies do not define the duration of postlaparoscopic pneumoperitoneum. In this study, we attempted to define the duration of laparoscopic pneumoperitoneum and to identify factors which affect resolution time. Methods: We followed 57 patients who underwent laparoscopic cholecystectomy (34), inguinal herniorraphy (20), or appendectomy (three). Serial abdominal films were taken until all residual gas was resolved. Results: Thirty patients resolved their pneumoperitoneum within 24 h; 16 patients resolved between 24 h and 3 days; nine patients resolved between 3 and 7 days; two patients resolved between 7 and 9 days. Mean resolution time for all patients was 2.6 ± 2.1 days. There was no apparent difference in resolution time between the three types of procedures; however, the sample size may be insufficient. Duration of the pneumoperitoneum did not correlate with gender, age, weight, initial volume of CO₂ used, length of time for the procedure, or postoperative complications. Sixteen patients had bile spillage during cholecystectomy which significantly reduced the duration of postoperative pneumoperitoneum (p < 0.008), resulting in a mean resolution time of 1.3 ± 0.9 days. While 14 patients reported postoperative shoulder pain, no correlation was found between the presence or duration of shoulder pain and the extent or duration of pneumoperitoneum. Conclusions: We conclude that the residual pneumoperitoneum following laparoscopic surgery resolves within 3 days in 81% of patients and within 7 days in 96% of patients. The resolution time was significantly less in patients sustaining intraoperative bile spillage during cholecystectomy. There was no correlation found between postoperative shoulder pain and the presence or duration of the pneumoperitoneum. Received: 22 March 1996/Accepted: 12 July 1996     

Recurrent locking of knee joint caused by intraarticular migration of bioabsorbable tibial interference screw after arthroscopic ACL reconstruction

Two cases are reported in which, after ACL reconstruction with autologous hamstring grafts, tibial polylactide interference screws migrated into the knee joint. Clinically, both patients presented with recurrent locking of the joint. In one case, a broken 15 mm-long tip of the screw was found intra-articularly. In the other case, the whole screw had migrated into the joint cavity. The degradation process of polylactic acid, operative technique and bone quality are discussed as possible reasons for these complications.     

老年髋部骨折术后患者康复需求程度与康复状况调查

目的了解老年髋部骨折术后患者康复需求程度、需求满足度与康复状况的关系.方法上门随访82例老年髋部骨折术后患者家庭康复现状和康复需求情况.结果康复需求10个维度中他人支持、康复信息及功能训练指导位居前3位;需求程度与生理功能、躯体功能和社会功能有关(P＜0.05,P＜0.01);与髋关节功能评分中的疼痛程度、上楼梯、穿鞋袜和行走距离4个方面有关(P＜0.05,P＜0.01).结论出院后定期给予针对性的康复训练指导和健康教育是患者迫切的需求;康复需求程度高者,相应需求满足率低,其生活质量及髋关节功能恢复应成为干预的重点.

亲属活体部分小肠移植术后早期并发症的防治

目的探讨亲属活体部分小肠移植术后早期并发症的防治。方法为3例短肠综合征患者和1例肠神经节缺失导致小肠无功能患者施行亲属活体部分小肠移植术,供、受者HLA配型均有4个以上抗原相合,供肠均取自回肠末端,长度为(150±10)cm,应用他克莫司、霉酚酸酯及甲泼尼龙预防排斥反应。术后采取抗凝、改善微循环、输注人白蛋白等措施调控患者的出、凝血功能,预防血管吻合口血栓形成和出血,给予法莫替丁或奥美拉唑预防应激性溃疡；给予头孢三代为主的抗生素、更昔洛韦以及氟康唑预防细菌、病毒及真菌感染,并注重对体表易感染部的消毒和护理；术后鼓励患者多下床活动,早期给予谷氨酰胺,尽早将营养支持治疗过渡为肠内营养,以促进移植肠功能的恢复。结果术后3d,1例患者发生肺部鲍曼不动杆菌感染,经抗生素治疗后控制。1例术后5 d移植肠系膜根部出现血肿,手术清除血肿。2例消化道分泌物及大便中发现真菌生长,给予氟康唑治疗后好转。4例在术后20 d左右均发生急性排斥反应,经加大FK506的用量,并以甲泼尼龙冲击治疗后逆转。4例患者,2例获得长期存活,至今分别存活6年8个月和3年2个月,另2例分别于术后5个月、35 d因感染死亡。结论小肠移植术后早期的并发症较多,与小肠的生理结构有关,术后早期并发症的成功防治是临床小肠移植成败的关键。     

关节镜技术的历史与新进展

现代的关节镜从膀胱镜演变而来，创伤小，适用广泛。近年膝关节镜技术在半月板病变处理上有逆行全切法等新方法，交叉韧带重建、软骨移植成为研究热点；关节镜技术除应用于肩关节及其它小间隙关节，还开展治疗弹响髓等关节外应用；个性化康复锻炼提高了手术疗效。     

Cardiac rehabilitation and return to work after coronary artery bypass surgery

The work situation of 66 male patients who underwent elective coronary artery bypass surgery (CABS) and who had been randomly allocated to receive cardiac rehabilitation (group R) was compared with the work situation of 59 similar patients allocated to receive only standard care (group H). The follow-up time was one year. The proportions of subjects working in groups R and H were 26% and 20% (p=ns) before the CABS, 45% and 34% (p=ns) 6 months and 56% and 38% (p=ns) 12 months after the CABS, repectively. The increase in proportion of subjects who worked was significant in both groups at both 6 and 12 months after the CABS (p<0.05 for all changes). The increases were not significantly different between the whole groups, but in patients younger than 55 years of age, return to work was more frequent in group R than in group H (at 12 months 60% vs. 35%, p for the difference in change=0.02). Stepwise logistic regression analysis of the factors influencing return to work showed that a patient's judgement of his own working capacity as good 6 months after CABS (odds ratio (OR) 8.5, confidence interval (CI) 2.3–32.0), functional class 16 months after the CABS (OR 6.7, CI 1.8–24.5), his desire to work (OR 6.4, CI 1.6–26.0) and absence from work of less than 3 months before the CABS (OR 4.9, CI 1.2–20.2) were significant positive predictors of return to work 1 year after the CABS.
