A, Kaplan-Meier survival plot illustrating the duration of convalescence from work (n = 85) and/or main recreational activity (n = 198) for patients recommended to have 2 days' convalescence. The duration to resume work was significantly longer than the duration to resume recreational activity (P<.001, log-rank test). B, Duration of convalescence from work (n = 25) and/or main recreational activity (n = 2) for patients recommended to have 1 week of convalescence. Since only 2 patients were recommended for 1 week of convalescence for recreational activity, the log-rank test for comparison was not performed.
Median self-registered fatigue scores after uncomplicated laparoscopic cholecystectomy in 108 consecutive patients (consecutive patients numbered 93-200). Fatigue was registered on a 10-point interval scale. Compared with preoperatively, fatigue scores were significantly increased (P<.001, Friedman test) until the fifth postoperative day (P = .04, day 3; P = .82, day 4; and P = .14, day 5, 6, and 7, Wilcoxon test) (Bonferroni correction for mass significance was P<.007).

Detailed information on duration and limiting factors for convalescence after uncomplicated laparoscopic cholecystectomy is lacking. Duration of convalescence may be associated with patients' expectations, given recommendations, and postoperative complaints such as pain and fatigue.
Prospective, descriptive study.
A university hospital.
Two hundred consecutive patients who underwent uncomplicated elective laparoscopic cholecystectomy.
For sedentary, light, or moderate workload or main recreational activity, we recommended 2 days of postoperative convalescence; for strenuous workload or recreational activity, we recommended 1 week.
Main Outcome Measures
Duration and reasons for absence from work.
Convalescence from work (n = 85) and recreational activity (n = 198) was 6 days (range, 0-28 days) and 2 days (range, 0-24 days), respectively, in patients recommended for 2 days' convalescence. In patients recommended for 1 week of convalescence, convalescence from work (n = 25) was 10 days (range, 0-52 days), and convalescence from main recreational activity (n = 2), 8 days (range, 5-11 days). Among 87 patients who resumed work or activity later than recommended, pain was a contributory cause in 41 patients, fatigue in 35 patients, and convalescent period falling on a weekend in 26 patients, while 29 patients had arranged vacation or sick leave preoperatively. Preoperative expectation of convalescence and pain were independent contributory factors (P<.01) for convalescence from work for longer than 2 days in patients recommended for 2 days' convalescence.
The period of convalescence after uncomplicated laparoscopic cholecystectomy is about 1 week from work and 2 days from recreational activity when 2 days of convalescence is recommended. Improved pain relief and patient information may further reduce convalescence.
CONVALESCENCE after laparoscopic cholecystectomy is often used as an outcome parameter, owing to its large socioeconomic impact and patient discomfort.1-4 Compared with open traditional cholecystectomy, laparoscopic cholecystectomy confers advantages such as reduced postoperative pain, immune and inflammatory responses, and pulmonary dysfunction.5 In randomized studies comparing different surgical techniques for cholecystectomy (traditional open, mini-incisional, and laparoscopic cholecystectomy),1-4 the median or mean postlaparoscopic cholecystectomy convalescence is surprisingly long, ranging from 1 to 3 weeks to resume recreational activities1-4 and 2 to 5 weeks to resume work.1,3,4,6 However, to our knowledge, no large-scale study has analyzed convalescence after uncomplicated laparoscopic cholecystectomy using short well-defined convalescence recommendations. Furthermore, specific information on the factors responsible for convalescence after laparoscopic cholecystectomy is lacking, and there is no scientific data to argue for prolonged convalescence after uncomplicated laparoscopic cholecystectomy. We have therefore prospectively analyzed limiting factors for short convalescence using standardized convalescence recommendations in patients undergoing uncomplicated laparoscopic cholecystectomy.
Our aim was to obtain valid prospective data on convalescence from 200 consecutive patients undergoing uncomplicated elective laparoscopic cholecystectomy. Patients with acute cholecystitis were not included. The setting was semi-ambulatory (patients were encouraged but not forced to be discharged from the hospital on the day of surgery) within a gastroenterologic surgery department in a public university hospital with unselected referral of patients. Collection of data was based on structured interviews and self-administered standardized questionnaires. All patients were contacted by telephone 1 week postoperatively for clinical control and to secure return of postoperative questionnaires. A 1-month follow-up for postoperative morbidity was performed in all patients.
In case of strenuous physical workload (ie, construction workers, day-care workers, furniture movers) or recreational activity (ie, energetic sporting activity), 1 week of convalescence was recommended (ie, 8 days' absence including the day of surgery). Two days of convalescence (ie, 3 days' absence including the day of surgery) was recommended for all other types of sedentary, light, or moderate work (ie, clerk, teacher, journalist, businessperson, postal worker) or recreational activity (sedentary hobby, watching television, going to the movies, walking, biking, shopping, gardening, exercising). All patients were informed that there were no postoperative restrictions and that work or recreational activity was allowed from the first postoperative day. Recommendations and information were given at the first preoperative ambulatory examination (verbally and in a folder) on the day before surgery and at hospital discharge.
At the first preoperative examination (prior to receiving information about the postoperative course and our recommendations), patients filled out a short questionnaire regarding their expectations of the duration of convalescence (convalescence was defined as sick leave or the period during which normal functions or activities were hindered). The categorical variables were given in 3 levels: 0 to 4 days, 1 week, and 2 weeks or more. To examine the influence of preoperative neuroticism on the duration of convalescence, a psychometric vulnerability test questionnaire7,8 was sent to patients preoperatively. Clinical information (preoperative health and physical examination, demographics, intraoperative data, etc) was obtained on preprinted forms. Information about occupation and recreational activities were obtained at personal interviews, and patients were stratified according to paid work (employee, self-employed) or not working (retired or unemployed) and to the level of main activity (sedentary, light, moderate, or heavy/strenuous) during work and/or recreational activity.
All patients received a similar general anesthetic regimen, including cisatracurium besylate (for induction, 0.15 mg/kg), fentanyl citrate (for induction, 0.003 mg/kg), propofol (maintenance, 10 mg/kg per hour), and supplemental doses of alfentanil hydrochloride (0.5-1.0 mg) if required. Premedication was not used. Fifty-three patients received incisional local anesthetics. The anesthetic regimen and infiltration technique for local anesthesia has been described in detail elsewhere.9 For postoperative analgesia all patients received intravenous ketorolac tromethamine (30 mg) approximately 20 minutes before the end of surgery, and in the recovery room, patients received acetaminophen (2 g) as suppositories. Three hours postoperatively, oral treatment with ibuprofen (600 mg every 8 hours for 4 days) was commenced (tablets were distributed to patients for self-administration). During hospitalization additional morphine was administered on request. All operations were conducted or supervised by experienced laparoscopic surgeons (J.R.) who used two 10-mm and two 5-mm trocars.
Participants completed a questionnaire on the day of returning to work and/or main recreational activity. If work and/or recreational activity were resumed later than recommended, responsible reasons (patients were allowed to give multiple reasons) were stated (pain, fatigue, wound problems, advice from general practitioner, hindered owing to weekend, planned vacation or sick leave prior to operation, or "other" [in case of other, details could be specified]). For 108 consecutive patients, numbered 93 to 200, fatigue and postoperative nausea and vomiting (PONV) were registered. Fatigue was registered on a 10-point interval scale covering the preceding 24 hours (1, fit; 10, fatigued)10 the day before surgery and daily during the first postoperative week. Nausea was registered on a verbal rating scale (0, no nausea; 1, light; 2, moderate; 3, severe), and vomiting episodes were noted covering 3 intervals: the day before surgery, and postoperative hours 0 to 6 and 6 to 24.
The Pearson χ2 test with Yates correction, Fisher exact test, Friedman 2-way analysis of variance by ranks, Mann-Whitney rank sum test, and Wilcoxon signed rank test with Bonferroni correction for mass significance were used when appropriate. The duration of convalescence from work and recreational activity was compared in patients receiving the same recommendations for convalescence by using Kaplan-Meier plots. Kaplan-Meier plots and a univariate log-rank test were also used to assess the influence of individual factors on convalescence from work in patients recommended for 2 days' convalescence. For this group of patients, significant factors to influence convalescence from work were included as categorical variables in a Cox proportional hazards model using the forward stepwise method (likelihood ratio). Data are given as median and ranges and percentages when appropriate. A probability of less than .05 was accepted as statistically significant. The local Ethics Committee approved the study, and patients gave their written informed consent to participate.
During the period from October 22, 1997, to June 25, 1999, 268 patients underwent elective laparoscopic cholecystectomy. Thirty patients were not included: 4 patients refused to participate in the study; 19 were not sufficiently compliant (non–Danish-speaking, drug addiction, or mental disorder); 4 were used as "pilot patients" in another study; and 3 were lost owing to summer vacation. Of the remaining 238 patients, 38 patients were excluded from the study (21 patients had postoperative complications; 12 underwent conversion to open procedure; and 5 did not return the postoperative registration questionnaire), leaving data from 200 patients for analysis. In these 200 patients, median age was 43 years (age range, 20-79 years). There were 170 women and 30 men. One hundred fifty-five patients had an American Society of Anesthesiologists physical status of I; 42, status II; and 3, status III. The median hospital stay was 1 night after surgery (range, 0-5 nights).
There were 110 employed patients (median age, 39 years [age range, 21-69 years]), 85 of whose main employment involved sedentary/light/moderate work (6 were self-employed, and 79 were employees). For the remaining 25 patients, the main workload was strenuous (all employees). The main recreational activity was characterized as sedentary/light/moderate in 198 patients and in 2 patients as strenuous (elite sport).
Convalescence data are given in Table 1 together with the main reasons for not following our recommendations to resume work and recreational activity. The duration of convalescence of those patients returning to work was significantly longer than the duration for those returning to recreational activity (P<.001) (Figure 1). Convalescence from work (n = 85) and recreational activity (n = 198) was 6 days (range, 0-28 days, including the day of surgery) and 2 days (range, 0-24 days), respectively, in patients recommended for 2 days' convalescence. The overall convalescence (pooled data from work and main recreational activity in patients recommended for 2 days' convalescence) was 3 days (range, 0-28 days).
In patients recommended for 1 week of convalescence, convalescence from work (n = 25) was 10 days (range, 0-52 days), and convalescence from main recreational activity (n = 2) was 8 days (range, 5-11 days). The overall convalescence period (pooled data from work and main recreational activity in patients recommended for 1 week of convalescence) was 10 days (range, 0-52 days).
Among the 87 patients who resumed work later than recommended, pain was contributory in 41 patients and fatigue in 35. In 26 patients, an interposed weekend hindered return to work within 2 days, and 29 patients had arranged vacation or sick leave prior to the operation. In 2 patients, PONV was reported as a contributory factor for not resuming work as recommended. Absence from main recreational activities was mainly owing to pain and fatigue (Table 1). Two patients reported that PONV was contributory for not resuming recreational activity as recommended. Fatigue scores were significantly increased until the fifth postoperative day (P<.001, Friedman test; P<.005 for days 1-4, Wilcoxon test; Figure 2). Among the 108 patients registered, 28, 52, and 33 complained of nausea before surgery and during postoperative hours 0 to 6 and 6 to 24, respectively. For the same intervals, 0, 19, and 7 patients vomited once or more.
Univariate analysis of the effect on convalescence of the following variables did not reach statistical significance: age, sex, use of incisional local anesthetics, preoperative neuroticism, type of workload (sedentary vs light vs moderate), or the fact that postoperative vacation or sick leave was planned preoperatively. Preoperative expectations to convalescence (P<.001) and the following 3 self-reported contributory factors were significantly related to the duration of convalescence (univariate analysis): postoperative pain (P<.001), fatigue (P<.02), and hindrance owing to an interposed weekend (P<.04). The result of the multivariate analysis showed that preoperative expectations regarding the duration of convalescence and postoperative pain were independently and significantly associated with convalescence from work (P<.01).
Our study has demonstrated that convalescence after uncomplicated laparoscopic cholecystectomy for patients recommended for 2 days' convalescence lasted for roughly 1 week from work and 2 days from recreational activity. Preoperative expectations to the duration of convalescence, pain, fatigue, and weekends were important contributory factors for prolonged duration of convalescence from work.
In the present study, individual factors to influence convalescence from work were analyzed only in the group of patients recommended for 2 days' convalescence. We did not analyze factors to explain convalescence from recreational activity and work in the group of patients recommended for 1 week of convalescence because of the small number of patients (∼25 patients) with strenuous work who were recommended for 1 week of convalescence.
In this study, convalescence data from patients converted to open procedure or having complications (wound infections, common bile duct stones) were not included since convalescence in these circumstances is variable and dependent on the nature of the given situation. In controlled studies investigating the effect of laparoscopic cholecystectomy (vs open or mini-incisional cholecystectomy) on convalescence, absence from work varies from 2 to 5 weeks1,4,6,11 and 1 to 3 weeks from recreational activity or leisure time.1,2,4,11 These studies comprised data from all patients, including patients with complications and operations converted to open procedures. Other large-scale randomized3 or retrospective descriptive studies12 of uncomplicated laparoscopic cholecystectomy reported 3 weeks of convalescence from work. As specific recommendations for the duration of convalescence were not given in any of the mentioned studies, it may be argued that these studies reflected, in part, tradition and medical treatment culture. Thus, Majeed et al13 reported that surgeons and general practitioners were recommended for 1 to 12 weeks' convalescence after laparoscopic cholecystectomy, depending on age and workload. Another study with 15 patients undergoing uncomplicated laparoscopic cholecystectomy6 used well-defined convalescence recommendations (if the patients were able to return to work, no further sick leave was allowed 1 week after surgery) and found that patients resumed work after a mean of 12 days.
In our study, we recommended 1 week of convalescence in case of strenuous workload or recreational activity. This differentiation was not scientifically based, but at the initiation of the study, we considered a recommendation of 2 days' convalescence for all types of work and activity too dramatic compared with current traditions. In 2 descriptive studies of patients undergoing laparoscopic cholecystectomy,12,14 the workload and status was significantly related to convalescence from work as patients with a moderate workload (vs heavy workload) and self-employed patients (vs employees) resumed work significantly earlier than others (about 2 weeks vs 3 weeks and 1 week vs 3 weeks, respectively). In our study, only 6 patients were self-employed, and this group was therefore not analyzed separately.
The present study is, to our knowledge, the first large-scale study to provide specific clinical information on factors influencing convalescence after laparoscopic cholecystectomy. Preoperative expectations of convalescence and pain as well as fatigue and the presence of an interposed weekend were important contributory factors to explain convalescence from work for longer than 2 days. Consequently, we recommend 2 days' convalescence as routine after uncomplicated laparoscopic cholecystectomy, but pain and fatigue may prolong convalescence in some patients.
