Internal hernia as a rare cause of small bowel obstruction:An insight from 13 years of experience

BACKGROUND Internal hernia(IH)is a rare culprit of small bowel obstruction(SBO)with an incidence of<1%.It poses a considerable diagnostic challenge requiring a high index of suspicion to prevent misdiagnosis,improper treatment,and subsequent morbidity and mortality.AIM To determine the clinico-demographic profile,radiological and operative findings,and postoperative course of patients with IH and its association with SBO.METHODS Medical records of 586 patients with features of SBO presenting at a tertiary care centre at Lucknow,India between September 2010 and August 2023 were reviewed.RESULTS Out of 586 patients,7(1.2%)were diagnosed with IH.Among these,4 had congenital IH and 3 had acquired IH.The male-to-female ratio was 4:3.The median age at presentation was 32 years.Contrast-enhanced computed tomography(CECT)was the most reliable investigation for preoperative identification,demonstrating mesenteric whirling and clumped-up bowel loops.Left paraduodenal hernia and transmesenteric hernia occurred with an equal frequency(approximately 43%each).Intraoperatively,one patient was found to have bowel ischemia and one had associated malrotation of gut.During follow-up,no recurrences were reported.CONCLUSION IH,being a rare cause,must be considered as a differential diagnosis for SBO,especially in young patients in their 30s or with unexplained abdominal pain or discomfort post-surgery.A rapid imaging evaluation,preferably with CECT,is necessary to aid in an early diagnosis and prompt intervention,thereby reducing financial burden related to unnecessary investigations and preventing the morbidity and mortality associated with closed-loop obstruction and strangulation of the bowel.

Small bowel obstruction due to intra-abdominal hernia:New thoughts on diagnosis and treatment

Internal herniation(IH)refers to the movement of intra-abdominal organs or tissues out of their original position through normal or abnormal orifices and fissures in the peritoneum or mesentery and into an anatomic space within the abdominal cavity.Although the incidence of small bowel obstruction(SBO)caused by IH is very low(approximately 0.2%to 0.9%),its incidence may be increased in certain specific populations or in postoperative patients.Recently Kaw et al shared their 13-year experience of managing IHs in a tertiary care hospital in India.This retrospective study analyzed and determined the clinico-demographic profiles,radiological and operative findings and postoperative course of patients with IH and the association with SBO.The results provide valuable insights into early diagnosis and establishment of a timely treatment regimen for this condition and emphasize the importance of combining rapid imaging evaluation with the traditional therapeutic approach of laparoscopic surgery,thus providing a novel perspective on the diagnosis and treatment of SBO caused by IH.

Intestinal Obstruction Due to an Internal Hernia through a Defect of the Broad Ligament in an Adult Female Patient: Case Report and Literature Review

Internal hernia is a rare cause of intestinal obstruction. We present a case of 43-year-old woman without any prior surgical history who was referred as a case of obstructed para-umbilical hernia from a satellite clinic. The objective is to highlight the occurrence of such a rare clinical problem and to provide an insight into decision making especially when there is discordance between an obvious pathology and clinical features.

Clinical evaluation of endoscopic biliary stenting in treatment of malignant obstructive jaundice

BACKGROUND Malignant obstructive jaundice(MOJ)is characterized by the presence of malignant tumors infiltrating or compressing the bile duct,causing poor bile drainage,generalized yellowing,pain,itching,and malaise.MOJ is burdensome for both the society and the families of affected patients and should be taken seriously.AIM To evaluate the clinical effect of stent placement during endoscopic retrograde cholangiopancreatography for relieving MOJ and the efficacy of percutaneous transhepatic biliary drainage in terms of liver function improvement,complication rates,and long-term patient outcomes.METHODS The clinical data of 59 patients with MOJ who were admitted to our hospital between March 2018 and August 2019 were retrospectively analyzed.According to the treatment method,the patients were divided into an observation group(29 patients)and a control group(30 patients).General data,liver function indices,complications,adverse effects,and 3-year survival rates after different surgical treatments were recorded for the two groups.RESULTS There were no significant differences in baseline information(sex,age,tumor type,or tumor diameter)between the two groups(P>0.05).Alanine aminotransferase,aspartate aminotransferase,and total bilirubin levels were significantly better in both groups after surgery than before surgery(P<0.05).The overall incidence of biliary bleeding,gastrointestinal bleeding,pancreatitis,and cholangitis was 6.9%in the observation group and 30%in the control group(P<0.05).No significant differences in the rates of blood transfusion,intensive care unit admission,or death within 3 years were observed between the two groups at the 1-month follow-up(P>0.05).The 3-year survival rates were 46.06%and 39.71%in the observation and control groups,respectively.CONCLUSION Endoscopic biliary stenting effectively relieves MOJ and significantly improves liver function,with minimal complications.This technique is a promising palliative approach for patients ineligible for radical surgery.However,further research is needed to optimize current treatment strategies and to explore their potential in treating nonmalignant cases of obstructive jaundice.

Is there a correlation between the outcome of transurethral resection of prostate and preoperative degree of bladder outlet obstruction？

To compare the impact of transurethral resection of prostate （TURP） on symptom scores and maximal flow rates （Qmax） in patients with equivocal bladder outlet obstruction （BOO） and definite BOO and to assess the relationship between the surgical outcomes and degree of preoperative BOO, we prospectively evaluated men with lower urinary tract symptoms and bladder outlet obstruction index （BOO1） greater than 20, who were refractory to conventional medical treatment and underwent TURP. Urodynamic evaluation, International Prostate Symptom Score （IPSS）, uroflowmetry, post-void residual volume （PVR） check and transrectal ultrasound were performed. 20〈B001〈40 was defined as equivocal BOO and BOO1 〉~40 as definite BOO. Changes of IPSS, Qmax, PVR and correlation analysis was performed between the degree of improvement of Qmax, subdomains of I PSS and BOO1. Fifty-four patients showed equivocal BOO and 80 patients showed definite BOO. Preoperatively equivocal BOO group and definite BOO group showed significant differences in maximal bladder capacity and prevalence of detrusor overactivity, whereas no difference was noted in prostate volume. Postoperatively both groups showed improvements in Qmax, obstructive （IPSSO） and irritative （IPSSI） subdomain of IPSS, but the degree of improvement in Qmax and IPSSI subdomain was statistically significantly greater in definite BOO group. The degree of improvement of Qmax and IPSSI showed weak correlation with preoperative BOO1. As a weak correlation was identified between preoperative degree of BOO and outcome of TURP, other factors other than BOO1 such as severity of patients＇ symptoms should be considered in deciding treatment modality.

Current status of laparoscopic and robotic ventral mesh rectopexy for external and internal rectal prolapse

External and internal rectal prolapse with their affiliated rectocele and enterocele, are associated with debilitating symptoms such as obstructed defecation, pelvic pain and faecal incontinence. Since perineal procedures are associated with a higher recurrence rate, an abdominal approach is commonly preferred. Despite the description of greater than three hundred different procedures, thus far no clear superiority of one surgical technique has been demonstrated. Ventral mesh rectopexy(VMR) is a relatively new and promising technique to correct rectal prolapse. In contrast to the abdominal procedures of past decades, VMR avoids posterolateral rectal mobilisation and thereby minimizes the risk of postoperative constipation. Because of a perceived acceptable recurrence rate, good functional results and low mesh-related morbidity in the short to medium term, VMR has been popularized in the past decade. Laparoscopic or robotic-assisted VMR is now being progressively performed internationally and several articles and guidelines propose the procedure as the treatment of choice for rectal prolapse. In this article, an outline of the current status of laparoscopic and robotic ventral mesh rectopexy for the treatment of internal and external rectal prolapse is presented.

Therapeutic effects of the TST36 stapler on rectocele combined with internal rectal prolapse

BACKGROUND The most common causes of outlet obstructive constipation(OOC)are rectocele and internal rectal prolapse.The surgical methods for OOC are diverse and difficult,and the postoperative complications and recurrence rate are high,which results in both physical and mental pain in patients.With the continuous deepening of the surgeon’s concept of minimally invasive surgery and continuous in-depth research on the mechanism of OOC,the treatment concepts and surgical methods are continuously improved.AIM To determine the efficacy of the TST36 stapler in the treatment of rectocele combined with internal rectal prolapse.METHODS From January 2017 to July 2019,49 female patients with rectocele and internal rectal prolapse who met the inclusion criteria were selected for treatment using the TST36 stapler.RESULTS Forty-five patients were cured,4 patients improved,and the cure rate was 92%.The postoperative obstructed defecation syndrome score,the defecation frequency score,time/straining intensity,and sensation of incomplete evacuation were significantly decreased compared with these parameters before treatment,and the differences were statistically significant(P<0.05).The postoperative anal canal resting pressure and maximum squeeze pressure in patients decreased compared with before treatment,and the differences were statistically significant(P<0.05).The initial and maximum defecation thresholds after surgery were significantly lower than those before treatment,and the differences were statistically significant(P<0.05).The postoperative ratings of rectocele,resting phase,and defecation phase in these patients were significantly decreased compared with those before treatment,and the differences were statistically significant(P<0.05).CONCLUSION The TST36 stapler is safe and effective in treating rectocele combined with internal rectal prolapse and is worth promoting in clinical work.

Left paraduodenal hernia presenting as recurrent small bowel obstruction

Internal hemiation of the small bowel is a relatively rare cause of intestinal obstruction. Left paraduodenal hernia resulting from abnormal rotation of the midgut during embryonic development is the most common form of congenital internal hernia. We report our experience in the diagnosis and management of a young male with left paraduodenal hernia presenting as recurrent intestinal obstruction. Correct preoperative diagnosis of left paraduodenal hernia had been difficult due to non-specific clinical presentations, but the advent of modern imaging technology makes early and correct diagnosis possible, Due to the risk of obstruction and strangulation, surgical treatment is indicated; however, timely intervention increases the likelihood of a favorable outcome.

Crohn’s disease complicated by multiple stenoses and internal fistulas clinically mimicking small bowel endometriosis

We report a 31-year-old woman with Crohn's disease complicated by multiple stenoses and internal fistulas clinically misdiagnosed as small bowell endometriosis, due to the patient's perimenstrual symptoms of mechanical subileus for 3 years; at first monthly, but later continuous, and gradually increasing in severity. We performed an exploratory laparotomy for small bowel obstruction, and found multiple ileal strictures and internal enteric fistulas. Because intraoperative findings were thought to indicate Crohn's disease, a right hemicolectomy and partial distal ileum resection were performed for obstructive Crohn's ileitis. Histopathology of the resected specimen revealed Crohn's disease without endometrial tissue. The patient made an uneventful recovery from this procedure and was discharged home 10 d post-operatively. The differential diagnosis of Crohn's diease with intestinal endometriosis may be difficult pre-operatively. The two entities share many overlapping clinical, radiological and pathological features. Nevertheless, when it is difficult to identify the cause of intestinal obstruction in a woman of child-bearing age with cyclical symptoms suggestive of small bowel endometriosis, Crohn's disease should be included in the differential diagnosis.

Efficacy of Bladder Neck Incision (BNI) Versus Transurethral Resection of Prostate (TURP) in Management of Benign Prostatic Hyperplasia (BPH) Causing Obstruction: A Randomised Controlled Study

Objective: To compare the efficacy of bladder neck incision (BNI) with transurethral resection of prostate (TURP) in the treatment of patients with urinary obstruction caused by benign prostatic hyperplasia (BPH) on the basis of short term follow up of 4 months. Patient and Methods: The study was conducted in Department of General Surgery in Maulana Azad Medical College, New Delhi. 60 men with proven clinical diagnosis of BPH of size 30 grams and less presenting with symptoms of bladder outlet obstruction (BOO) were randomised prospectively to undergo either of the two operative modalities. Preoperatively size of the prostate, symptom scoring (IPSS), peak flow rate (Qmax) were assessed. Postoperatively and during 4 months follow up the following data were collected—operative time, catheterisation period, hospital stay, blood loss, Qmax and IPSS. Results: Preoperative parameters in both the groups showed no statistically significant differences with respect to prostate size, Qmax and IPSS Scoring. At 4 months follow up Qmax increased from (6.35 ± 4.49) to (16.41 ± 2.28) in TURP group and (4.51 ± 3.57) to (15.95 ± 2.58) in BNI group. IPSS decreased from 18.70 to 5.7 in TURP group and 18.90 to 6.00 in BNI group. All differences were statistically significant. There was a statistically significant difference in operative time, blood loss, hospital stay, catheterisation timing favouring BNI. Conclusion: TURP and BNI are equally effective in providing symptomatic improvement. BNI has an upper hand in reference to operative time, hospital stay, duration of catheterisation and blood loss.

A Rare Fatal Case of Internal Hernia Caused by Meckel’s Diverticulum in a Paediatric Patient

We describe a very rare case of an internal hernia associated with a Meckel’s diverticulum, which lead to the death of a young 3 year old boy. The case describes symptoms of abdominal pain and vomiting, on a background of previous intermittent abdominal pain. The possibility of small bowel obstruction was suspected, and appropriate imaging was performed. This case illustrates the need for a high index of suspicion for small bowel obstruction, with appropriate investigations and review. It also highlights the limitations of imaging modalities in identifying complications of Meckel’s diverticulum. It is important to raise awareness of this fatal cause for small bowel obstruction and to help identify suggestive imaging features, which may point towards a possible complicated Meckel’s diverticulum. Earlier recognition and diagnosis could reduce morbidity and mortality.

Transverse mesocolic hernia with intestinal obstruction as a rare cause of acute abdomen in adults:A case report

BACKGROUND Internal hernia is a rare cause of acute abdomen and intestinal obstruction in adults.Internal abdominal hernias include paraduodenal,perigastric,foramen of Winslow,intersigmoid,and post-anastomotic hernias and can be congenital or acquired.Internal hernias occur in 1%-2%of patients,and transmesocolic hernias are extremely rare.This report presents a patient with a transverse mesocolic hernia with a preoperative diagnosis of small intestinal obstruction.CASE SUMMARY A 45-year-old Chinese woman was admitted to the hospital with middle and upper abdominal pain for 2 d,abdominal distension,and vomiting.After abdominal computed tomography,she was diagnosed with an internal abdominal hernia complicated by small intestinal obstruction and underwent emergency laparoscopic surgery.The patient recovered well and was discharged 6 d postoperatively.CONCLUSION Transmesocolic hernias must be considered in adult patients with signs and symptoms of intestinal obstruction,even without a history of abdominal trauma or surgery.

Effect of nocturia in patients with different severity of obstructive sleep apnea on polysomnography: A retrospective observational study

Patients with suspected OSA were examined using PSG.They were divided into two groups based on the presence of nocturia.Nocturia was defined as a patient who needed to void at least once.Apneaehypopnea index(AHI)was employed to classify patients according to degrees of severity:AHI<5 events/h,5 events/hAHI<15 events/h,15 events/hAHI<30 events/h,and AHI30 events/h,defined as normal,mild OSA,moderate OSA,and severe OSA,respectively.Demographic variables,PSG parameters,International Prostate Symptom Scores(IPSSs),and quality of life scores due to urinary symptoms were analyzed.Results:In total 140 patients,114 patients had OSA(48 had mild OSA;34 had moderate OSA;and 32 had severe OSA)and 107 patients had nocturia.The total IPSS was significantly higher in nocturia patients in all groups except the group of severe OSA patients.With the increasing severity of OSA,more correlated factors related to nocturia were determined.In mild OSA patients,nocturia related to increased age(p=0.025),minimum arterial blood oxygenation saturation(p=0.046),and decreased AHI of non-rapid eye movement(p=0.047),AHI of total sleep time(p=0.010),and desaturation index(p=0.012).In moderate OSA patients,nocturia related to increased age(p<0.001),awake time(p=0.025),stage 1 sleep(p=0.033),and sleep latency(p=0.033),and decreased height(p=0.044),weight(p=0.025),and sleep efficiency(p=0.003).In severe OSA patients,nocturia related to increased weight(p=0.011),body mass index(p=0.009),awake time(p=0.008),stage 1 sleep(p=0.040),arousal number(p=0.030),arousal index(p=0.013),periodic limb movement number(p=0.013),and periodic limb movement index(p=0.004),and decreased baseline arterial blood oxygenation saturation(p=0.046).Conclusion:Our study revealed that there were more correlated factors related to nocturia with increasing severity of OSA.This study helps in clinical education and treatment for OSA patients with different severity.

Parietal peritoneal hernia after abdominal hysterectomy for forty years: A case report

BACKGROUND Internal hernia is a rare complication following abdominal surgery,primarily resulting from structural defects caused by anastomosis.We report a unique case of a late abdominal wall internal hernia highly suspected as resulting from insu-fficient peritoneal closure.CASE SUMMARY A 72-year-old woman presented with symptoms of intestinal obstruction 40 years after undergoing an abdominal hysterectomy.Abdominal computed tomography revealed a suspicious closed loop of intestine;then,a laparotomy was performed for suspected internal hernia.During the procedure,herniation of intestine into the preperitoneal space through a parietal peritoneal defect between rectus abdominis and sigmoid colon was identified.Intestinal reduction,resection of the ischemic segment and closure of the peritoneal defect were performed.The patient recovered well.CONCLUSION Non-closure of peritoneum might lead to late internal hernias.Meticulous peritoneal closure should be considered to prevent this potentially lethal complication.

功能性胃肠病从“三焦胀”辨治探讨

功能性胃肠病的病理本质是以三焦腑功能受损,进而病及脾胃,导致脾胃功能失调,兼及心失藏神、肝失疏泄、肺失宣肃、肾(膀胱)失气化表现的多系统多方位的临床综合征。“三焦胀”是以三焦气机升降失司导致气机不畅或逆乱为核心、以脾胃功能失调为基本症状,兼及其他脏腑功能失调的脾胃综合征,与功能性胃肠病的各类症状具有高度类同性。三焦与脾胃的关系密切,三焦气机失调容易引发脾胃病症状,说明“三焦胀”与功能性胃肠病具有内在联系。其辨证应以三焦功能为核心,以调复三焦气化为根本,力求“三焦胀”与功能性胃肠病的病、证、理、法、方、药的有机统一,体现临床证治一元论、精准度、靶向性,提高功能性胃肠病的临床疗效。功能性胃肠病表现为“三焦胀”类同症状时常可分为以下4种证型辨治:腠理失通型、三焦郁热型、相火僭越型、水道壅滞型;常用方剂有小柴胡汤、柴胡桂枝汤、旋覆代赭汤、生姜泻心汤、栀子豉汤、乌梅丸等。

Procedure for prolapse and hemorrhoids vs traditional surgery for outlet obstructive constipation

AIM: To compare the clinical efficacies of two surgical procedures for hemorrhoid rectal prolapse with outlet obstruction-induced constipation.METHODS: One hundred eight inpatients who underwent surgery for outlet obstructive constipation caused by internal rectal prolapse and circumferential hemorrhoids at the First Affiliated Hospital of Xinjiang Medical University from June 2012 to June 2013 were prospectively included in the study.The patients with rectal prolapse hemorrhoids with outlet obstructioninduced constipation were randomly divided into two groups to undergo either a procedure for prolapse and hemorrhoids(PPH)(n = 54) or conventional surgery(n = 54; control group).Short-term(operative time,postoperative hospital stay,postoperative urinary retention,postoperative perianal edema,and postoperative pain) and long-term(postoperative anal stenosis,postoperative sensory anal incontinence,postoperative recurrence,and postoperative difficulty in defecation) clinical effects were compared between the two groups.The short- and long-term efficacies of the two procedures were determined.RESULTS: In terms of short-term clinical effects,operative time and postoperative hospital stay were significantly shorter in the PPH group than in the control group(24.36 ± 5.16 min vs 44.27 ± 6.57 min,2.1 ± 1.4 d vs 3.6 ± 2.3 d,both P < 0.01).The incidence of postoperative urinary retention was higher in the PPH group than in the control group,but the difference was not statistically significant(48.15% vs 37.04%).Theincidence of perianal edema was significantly lower in the PPH group(11.11% vs 42.60%,P < 0.05).The visual analogue scale scores at 24 h after surgery,first defecation,and one week after surgery were significantly lower in the PPH group(2.9 ± 0.9 vs 8.3 ± 1.1,2.0 ± 0.5 vs 6.5 ± 0.8,and 1.7 ± 0.5 vs 5.0 ± 0.7,respectively,all P < 0.01).With regard to long-term clinical effects,the incidence of anal stenosis was lower in the PPH group than in the control group,but the difference was not significant(1.85% vs 5.56%).The incidence of sensory anal incontinence was significantly lower in the PPH group(3.70% vs 12.96%,P < 0.05).The incidences of recurrent internal rectal prolapse and difficulty in defecation were lower in the PPH group than in the control group,but the differences were not significant(11.11% vs 16.67% and 12.96% vs 24.07%,respectively).CONCLUSION: PPH is superior to the traditional surgery in the management of outlet obstructive constipation caused by internal rectal prolapse with circumferential hemorrhoids.

Abdominal ventral rectopexy with colectomy for obstructed defecation syndrome:An alternative option for selected patients

BACKGROUND Abdominal ventral rectopexy(AVR)with colectomy is controversial in the treatment of obstructed defecation syndrome(ODS).Literature data on this technique for ODS are very limited.AIM To evaluate the safety and efficacy of AVR with colectomy for selected patients with ODS.METHODS Consecutive patients who underwent AVR with colectomy for ODS were identified prospectively from 2016 to 2017 in our department.Patient demographics,perioperative surgical results,and postoperative follow-up outcomes were collected and analyzed.Long-term follow-up was evaluated with standardized questionnaires.The severity of symptoms was assessed by the objective Wexner Constipation Score(WCS)and ODS Score.The quality of life was assessed by the Patients Assessment of Constipation Quality of Life score.Functional outcome was compared pre-and post-operatively for each patient.The primary outcomes were determined by the improvement in symptoms and quality of life.Secondary outcome measures were operating time,postoperative length of stay,morbidity and mortality,improvement of pelvic floor structure,and patient satisfaction.RESULTS Four patients underwent robotic-assisted surgery,and two patients underwent a laparoscopic-assisted procedure.The mean operating time for the robotic approach was 243 min(range 160–300 min),and the mean operating time for the laparoscopic approach was 230 min(range 220-240 min).The mean postoperative length of stay was 8.2 d(range 6-12 d).There was no conversion to open procedure and no postoperative mortality.No urinary retention,wound infection,prolonged ileus,pelvic infection and anastomosis leakage occurred.Six patients were followed up for 36 mo.The WCS,ODS,and Patients Assessment of Constipation Quality of Life score improved significantly postoperatively(P<0.05).The WCS and ODS scores showed the best remission and stabilization at 6 to 12 mo after surgery.There was no recurrence or novel constipation after surgery.None of the patients used laxative medication.CONCLUSION Robotic and laparoscopic-assisted ventral rectopexy with colectomy is a safe and effective procedure for selected patients with ODS.However,comprehensive preoperative evaluation and careful patient selection are essential.

基于“痰浊内阻”与“脂代谢紊乱”的联系论治结肠腺瘤复发与恶变

结直肠腺瘤作为结直肠癌的重要癌前病变,内镜下切除虽作为首要治疗手段,但腺瘤复发率较高,如何预防腺瘤的发生,阻断腺瘤癌序列的进展是我们的研究方向。中医理论中“痰浊内阻”是结肠腺瘤发生与复发的主要原因,并且“痰浊”与“脂代谢”二者联系密切,因此本文将就“痰浊内阻”与“脂代谢紊乱”在结肠腺瘤中的联系进行讨论,探讨结肠腺瘤“痰浊内阻”的现代生物学内涵。通过探讨二者之间的联系可为临床治疗结肠腺瘤提供思路,同时还可将其运用到其他有关痰浊内阻、脂代谢紊乱的疾病中,以扩展临床诊治思维。

“老年慢性阻塞性肺疾病全周期康复评估与治疗”呼吸与康复专家共识

慢性阻塞性肺疾病(COPD)是主要的慢性气道疾病之一,60岁以上的老年人群患病率最高,严重影响老年患者的身体健康。国内外COPD防治指南均推荐肺康复治疗作为药物治疗的协同手段和有效补充,肺康复能够明显提高患者的呼吸功能和体能,减轻症状,降低住院率和病死率。但处于不同疾病时期的老年COPD患者接受肺康复的具体内容不同。本专家共识详细阐述了急性发作期、急性发作缓解期、门诊稳定期老年COPD肺康复的评估及治疗内容,以期为不同疾病时期老年COPD患者的肺康复治疗提供指导。本共识认为老年COPD患者常见功能障碍主要包括呼吸功能障碍、运动耐受功能障碍、精神心理问题、吞咽功能障碍和认知功能障碍;建议基于《国际功能、残疾和健康分类》(ICF)框架下,从身体结构、身体功能(呼吸功能、心脏功能、运动功能、精神心理及认知功能、吞咽功能和营养因素)、活动和参与、环境因素4个方面对老年COPD多功能障碍患者进行整体评估。肺康复治疗适用于所有出现相关症状和/或急性加重风险较高的患者(高级证据),但随着病情的转归和变化,康复参与团队、治疗方案和治疗地点也应及时地调整,形成全周期康复循环。戒烟是延缓肺功能下降与COPD进展的重要干预措施(高级证据);通过合理的营养支持,老年COPD患者可以改善营养状况,提高体力和生活质量,从而更好地管理疾病并促进康复(低-中级证据);对于晚期COPD静息状态下仍处于低氧血症的患者建议氧疗(低-中级证据);一些新型的康复治疗(如神经肌肉电刺激、针灸、部分中药等)可能对老年COPD患者有一定价值(低-中级证据)。本专家共识根据老年COPD患者的不同阶段将康复治疗分为一期肺康复、二期肺康复、三期肺康复,并就不同阶段康复治疗的针对人群、实施地点、康复内容、评估内容、参与学科和康复目标进行细分,强调临床呼吸专科医生、基层医生、康复医生/康复治疗师、护理人员、营养科医生、精神心理科医生、社会工作者等多学科人员应积极协调、共同配合,协同参与老年COPD患者全周期康复过程。
