Laparoscopic cholecystectomy. Treatment of choice for symptomatic cholelithiasis.

Our initial experience with laparoscopic cholecystectomy (LC) for symptomatic cholelithiasis has involved 152 patients. Patient age ranged from 17 to 83 years; most were female (78%). Their average weight was 170 pounds (range, 75 to 365 lbs.). Twenty-two per cent had a single gallstone, while 9% had two to three stones and 64% had more than three stones. Exclusion criteria initially included upper abdominal scarring, severe acute cholecystitis, choledocholithiasis, and inability to tolerate general anesthesia. The first two of these are now only relative contraindications with increased experience. Thirteen of the one hundred fifty-two procedures (8.5%) required conversion to an open operation. Average time of operation was 138 minutes. Intraoperative cholangiography was attempted in 78% of cases and was completed successfully in 66% of those attempted. There have been no deaths. The complication rate has been low: 4% major, 0% life-threatening, and 7.2% minor complications. Postoperative analgesic requirements are remarkably low: 36% of patients required no narcotics after leaving the recovery room. Eighty-seven per cent of patients successfully undergoing LC were discharged by the first postoperative day. Most patients resumed normal activities within 1 week after discharge. Laparoscopic cholecystectomy offers the majority of patients with symptomatic cholelithiasis an improved treatment option, resulting in significantly less postoperative pain, hospitalization, and recuperation time.

Psychosocial evaluation of bariatric surgery candidates: a survey of present practices.

Objective: Successful outcome for bariatric surgery is largely dependent on patients’ ability to adhere to postoperative behavior changes. A thorough psychological evaluation is often required before patients’ approval for surgery. In addition to a standard psychiatric interview, assessment of behavioral components specific to this surgery seems indicated. No uniform guidelines exist on how to conduct such an evaluation. This survey was designed to collect information on the level of involvement of mental health professionals with bariatric surgery programs and their approach to evaluating bariatric surgery candidates. Methods: Surveys about psychological evaluation practices were mailed to 188 bariatric surgery programs. Eighty-one surveys were returned. Results: Eighty-eight percent of programs require patients to undergo a psychological evaluation and almost half require formal standardized psychological assessment. Current illicit drug use, active symptoms of schizophrenia, severe mental retardation, and lack of knowledge about the surgery were the most commonly cited contraindications, preventing patients from gaining approval for surgery. Discussion: The majority of programs use psychological evaluations; however, the exclusion criteria for surgery vary greatly. Establishing uniform guidelines for the screening of bariatric surgery candidates is necessary. Suggestions on how to begin this process are provided. More research about behavioral and cognitive predictors of postsurgical success is needed. OCD = obsessive compulsive disorder.

Outpatient laparoscopic cholecystectomy: patient outcomes after implementation of a clinical pathway.

ObjectiveTo determine the success of a clinical pathway for outpatient laparoscopic cholecystectomy (LC) in an academic health center, and to assess the impact of pathway implementation on same-day discharge rates, safety, patient satisfaction, and resource utilization. Summary Background DataLaparoscopic cholecystectomy is reported to be safe for patients and acceptable as an outpatient procedure. Whether this experience can be translated to an academic health center or larger hospital is uncertain. Clinical pathways guide the care of specific patient populations with the goal of enhancing patient care while optimizing resource utilization. The effectiveness of these pathways in achieving their goals is not well studied. MethodsDuring a 12-month period beginning April 1, 1999, all patients eligible for an elective LC (n = 177) participated in a clinical pathway developed to transition LC to an outpatient procedure. These were compared with all patients undergoing elective LC (n = 208) in the 15 months immediately before pathway implementation. Successful same-day discharges, reasons for postoperative admission, readmission rates, complications, deaths, and patient satisfaction were compared. Average length of stay and total hospital costs were calculated and compared. ResultsAfter pathway implementation, the proportion of same-day discharges increased significantly, from 21% to 72%. Unplanned postoperative admissions decreased as experience with the pathway increased. Patient characteristics, need for readmission, complications, and deaths were not different between the groups. Patients surveyed were highly satisfied with their care. Resource utilization declined, resulting in more available inpatient beds and substantial cost savings. ConclusionsImplementation of a clinical pathway for outpatient LC was successful, safe, and satisfying for patients. Converting LC to an outpatient procedure resulted in a significant reduction in medical resource use, including a decreased length of stay and total cost of care.

Primary payer status affects mortality for major surgical operations.

Objectives:Medicaid and Uninsured populations are a significant focus of current healthcare reform. We hypothesized that outcomes following major surgical operations in the United States is dependent on primary payer status. Methods:From 2003 to 2007, 893,658 major surgical operations were evaluated using the Nationwide Inpatient Sample (NIS) database: lung resection, esophagectomy, colectomy, pancreatectomy, gastrectomy, abdominal aortic aneurysm repair, hip replacement, and coronary artery bypass. Patients were stratified by primary payer status: Medicare (n = 491,829), Medicaid (n = 40,259), Private Insurance (n = 337,535), and Uninsured (n = 24,035). Multivariate regression models were applied to assess outcomes. Results:Unadjusted mortality for Medicare (4.4%; odds ratio [OR], 3.51), Medicaid (3.7%; OR, 2.86), and Uninsured (3.2%; OR, 2.51) patient groups were higher compared to Private Insurance groups (1.3%, P < 0.001). Mortality was lowest for Private Insurance patients independent of operation. After controlling for age, gender, income, geographic region, operation, and 30 comorbid conditions, Medicaid payer status was associated with the longest length of stay and highest total costs (P < 0.001). Medicaid (P < 0.001) and Uninsured (P < 0.001) payer status independently conferred the highest adjusted risks of mortality. Conclusions:Medicaid and Uninsured payer status confers increased risk-adjusted mortality. Medicaid was further associated with the greatest adjusted length of stay and total costs despite risk factors or operation. These differences serve as an important proxy for larger socioeconomic and health system-related issues that could be targeted to improve surgical outcomes for US Patients.

The effect of ambulation on recovery from postoperative ileus.

To determine whether ambulation hastens recovery from ileus following laparotomy, 34 patients were studied, 10 of whom followed an ambulatory regimen beginning on postoperative day 1 (group A). The other 24 patients (group C did not become ambalatory until postoperative day 4. All patients underwent placement of seromuscular bipolar recording electrodes on the Roux limb, If present, stomach, Jejunum, and colon at laparotomy. Group A was recorded before and after ambutation so comparisons could be made to determine if ambulation had an acute effect on myoelctric activity. Group A preambulation and group C recordings were compared to judge whether there was an overall effect of ambulation on myoelectrlc recovery. No effect on slow wave frequency or percentage of slow waves with associated spike potentials was noted acutely or overall in the stomach, colon, or jejunum In continuity with the duodenal pacemaker. Transient increases in phase II spike activity in patients having a ROHX limb and their jejunum distal to the enteroenterostomy were noted on postoperative days 1 to 2, but these differences resolved by postoperative days 3 or 4. The data suggest that ambulation as a means to help resolve postoperative ileus and its accompanying cramps and bloating may be more perceived than real.

Laparoscopic cholecystectomy in the obese patient

The authors experience with laparoscopic cholecystectomy (LC) in obese (O, n = 96) and morbidly obese (MO, n = 27) patient groups was compared with that in the normal weight (NW, n = 174) group of patients as well as the whole group (WG). There were no operative deaths. There were no significant differences between groups for any of the following: successful intraoperative cholangiography (WG, 52.2%; NW, 52.9%; O, 51.1%; MO, 55.6%), conversion to open cholecystectomy (WG, 9.6%; NW, 9.2%; O,10.4%; MO, 11.1%), incidence of major complications (WG, 4.1%; NW, 3.4%, 0.5.2%; MO, 0%), incidence of minor complications (WG, 7.4%, NW, 7.5%; O,6.3%; MO, 3.7%), and length of hospitalization after successful LC (WG, 1.25 days; NW, 1.31 days; 0,1.16 days; MO, 1.13 days). Duration of operation did not differ, except LC in the MO group (136.4 ± 6.9 minutes) was longer when compared with NW patients (123.0 ± 2.9 minutes, p < 0.05). The authors conclude LC is a safe and effective treatment for obese patients with symptomatic cholelithiasis.

Laparoscopic Versus Traditional Appendectomy for Suspected Appendicitis

We compared the results of concurrently performed laparoscopic versus open appendectomy as treatments for suspected acute appendicitis. The 68 laparoscopic procedures resulted in 62 appendectomies, 47 by the laparoscopic (LA) technique and 15 by the open (LO) technique. Another 54 patients underwent open appendectomy (OA). Significantly more females underwent laparoscopy (LA and LO: 52% versus OA: 33%, p = 0.047). Operative duration was shortest for OA (81 +/- 3 minutes), which was shorter than for LO (108 +/- 7 minutes), but not different than LA (86 +/- 6 minutes). The postoperative length of stay was not different for LA (3.5 +/- 0.5 days) compared with OA (5.9 +/- 1.6 days) or LO (4.8 +/- 1.3 days). One death occurred in the OA group. Wound complication rates were not significantly different for LA (4.3%) compared with OA (9.4%) and LO (13.3%). Overall complication rates were lower for LA (10.6%) and OA (18.9%) compared with LO (46.7%, p < 0.01). Median hospital cost for LO (

5,220). When appendicitis was not present, definitive confirmation of pathology was achieved in 9 of 18 patients undergoing LA versus 4 of 14 patients having OA (p = not significant). We conclude that when laparoscopy and laparoscopic appendectomy can be performed, the procedure is safe and produces results comparable with those of open appendectomy without significant overall cost differences.
