Rectal cancer. Is the surgeon the variable in the outcome?

Four factors influence the outcome of rectal surgery: tumour biology, stage of lesion, type of surgery performed and the performing surgeon himself. Tumour biology and tumour stage depend on each other and are not influenced on by the surgeon, while he seems to have a great influence on the latter two factors. This influence mainly consists of the following: training, volume, individual skill and experience.     

Is calcium indicated in resuscitation? Experimental studies in dogs

This study compares the effect of epinephrine (11 dogs) with that of the combination of epinephrine with calcium (10 dogs) in CPR after anoxial cardiac arrest. In the epinephrine group resuscitation was successful in all 11 dogs within 4 minutes. In the calcium group only 7 out of 10 dogs could be resuscitated: 3 dogs died during CPR in cause of irreversible fibrillation (2 cases) and "stone heart" (1 case). High CPK-activity reflected severe myocardial cell damage. In the survivors of the calcium group cardiac function was significantly impaired: 1. decreased left ventricular pressure (LVP) and contractility (dp/dt max), 2. increased afterload, 3. decreased cardiac output inspite of increased heart rate, 4. as a consequence, reduced perfusion of the vital organs. - These results foster the conclusion that calcium should not be used henceforth in CPR. Epinephrine was and is still the drug of choice in resuscitation after cardiac arrest.     

Factors affecting long-term satisfaction after thoracic sympathectomy for palmar and plantar hyperhidrosis. Is the sudomotor reflex the only villain?

The main objective of this study was to determine if there are variations in the level of improvement of the palmar and plantar hyperhidrotic symptoms, as well as the incidence and intensity of the sudomotor reflex, throughout the seasons of the year, after thoracic sympathectomy for hyperhidrosis. The study also looks for the real impact of these variables in the long-term satisfaction. A cohort of 75 patients was followed through distinct seasons. A multivariate analysis was performed to identify possible variables responsible for dissatisfaction. Both the palmar (P=0.002) and plantar (P<0.001) symptoms and the presence and the intensity of the sudomotor reflex varies significantly throughout the seasons of the year. The sudomotor reflex was the main factor associated with low satisfaction in our patients in the summer (P=0.025) and winter (P<0.001) but in spring the lack of improvement in the hyperhidrosis in the foot was the unique factor related to dissatisfaction (P<0.001). The sudomotor reflex is the main negative factor in the summer and in the winter, independent of its intensity. However, at least in spring, the lack of removal of the plantar symptoms had a negative impact on satisfaction.     

Functional Recovery Period after Arthroscopic Rotator Cuff Repair: Is it Predictable Before Surgery?

Background  

Several studies have reported functional recovery of the shoulder after arthroscopic rotator cuff repair (ARCR). Preoperative estimation of the time required for functional recovery is important for determining surgical indications and for planning timing of the surgery and an appropriate postoperative physical therapy.     

Is the preservation of the phrenic nerve important after pneumonectomy?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was: is the preservation of the phrenic nerve important after pneumonectomy? Altogether more than 49 papers were found using the reported search, of which four represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. We conclude that care should be taken to preserve the integrity of the phrenic nerve wherever possible. The abnormal diaphragmatic motion which occurs as a consequence of phrenic nerve damage significantly reduces expiratory lung volumes, gas exchange and exercise capacity in already compromised patients. Phrenic nerve injury can also lead to a prolonged need for mechanical ventilation; this alone carries a risk of complication, such as infection. Plication of the paralyzed hemi-diaphragm has proved effective in reducing respiratory insufficiency after pneumonectomy. The aim of this is to fix and flatten the diaphragm, thus mimicking the role of a functioning phrenic nerve. Furthermore, the function of a preserved phrenic nerve remains normal for up to 11 years post pneumonectomy. Therefore, deterioration in function may highlight a recurrence in disease or a change in the post pneumonectomy space.     

Local recurrent cancer after radical prostatectomy and incontinence. Is the artificial urinary sphincter a useful therapeutic option?

OBJECTIVE: The artificial sphincter AMS AS 800 is the treatment of choice in postprostatectomy urinary incontinence. However, when the incontinence is combined with a local tumour recurrence, the insertion of an artificial sphincter may pose a problem. Tumour mainly localised at the site of the anastomosis could cause problems with the insertion of the cuff. It is also questionable whether this elaborate and expensive operation is appropriate in patients with a progressive carcinoma. MATERIALS AND METHODS: The charts of 220 patients who received a bulbar artificial sphincter between 1986 and 1996 were reviewed. Five patients were selected who suffered from simultaneous urinary incontinence and local recurrence of prostate cancer. The follow-up of these patients was between 18 and 70 months. RESULTS: In all 5 patients the implantation of the artificial sphincter at the bulbous urethra could be performed without any complications. All patients were continent during follow-up. Two changes of the cuff were necessary due to tissue shrinkage of the urethra below the cuff. One patient, 2 years after local excision of recurrent prostate cancer, was found, during implantation, to have a macroscopically inconspicuous though histologically tumour-infiltrated area. In the follow-up 5 years after the implantation his prosthesis is still working well. CONCLUSIONS: Even with local recurrence of prostatic carcinoma after radical prostatectomy, the patients' prognosis 'quo ad vitam' is not bad. The follow-up of patients proves that they profit from implantation of an artificial sphincter in terms of better quality of life. Sphincter-related complications are not more frequent than in comparable groups of patients without local recurrence.     

Is the Dislocation Rate Higher after Bipolar Hemiarthroplasty in Patients with Neuromuscular Diseases?

Background  

Patients with neuromuscular disease reportedly have a higher incidence of postoperative dislocation after bipolar hemiarthroplasty. Although the literature has focused on a high prevalence of preoperative neurologic conditions in patients who had dislocations after bipolar hemiarthroplasties, the relative incidence of dislocation in patients with neuromuscular disease and without is unclear.     

Is supplemental regional anesthesia associated with more complications and readmissions after ankle fracture surgery in the inpatient and outpatient setting?

BackgroundThere is concern that regional anesthesia is associated with increased risk of complications, including return to the hospital for uncontrolled pain once the regional anesthetic wears off.MethodsRetrospective database review of patients who underwent open reduction and internal fixation of a closed ankle fracture from 2014–16 who received general anesthesia alone (GA) or general anesthesia plus regional anesthesia (RA).Results9459 patients met inclusion criteria. Patients in the RA group had significantly longer operative duration in both inpatient (GAI = 71 min vs RAI = 79 min, p = 0.002) and outpatient setting (GAO = 66 min vs RAI = 72 min, p < 0.001), lower overall LOS (GA = 1.7 days vs RA = 1.1 days, p < 0.001), and higher readmission rate for pain (RAO = 4 [0.3%] vs GAO = 1 [0.0%], p = 0.007).ConclusionsPatients who received supplemental regional anesthesia had shorter hospital LOS, increased operative time, and increased readmission rates for rebound pain. However, the small number of patients needing readmission are not clinically significant demonstrating that regional anesthesia is safe, effective and readmission for rebound pain should not be a concern.Level of EvidenceIII.     

Quality of Life in Patients after Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: Is It Worth the Risk?

Objective

To investigate the course of health-related quality of life (HQL) over time in patients with peritoneal carcinomatosis (PC) after complete cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC).

Methods

Prospective, single-center, nonrandomized cohort study using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire.

Results

Ninety patients who underwent CRS and HIPEC for PC in our institution were enrolled in the study. Mean age was 56 years (range 27–77 years) (61 % female). Primary tumor was colorectal in 21 %, ovarian in 19 %, pseudomyxoma peritonei in 16 %, an appendix tumor in 16 %, gastric cancer in 10 %, and peritoneal mesothelioma in 13 % of cases. Mean peritoneal carcinomatosis index was 22 (range 2–39). Mean global health status score was 69 ± 25 preoperatively and 55 ± 20, 66 ± 22, 66 ± 23, 71 ± 23, and 78 ± 21 at months 1, 6, 12, 24, and 36, respectively. Physical and role function recovered significantly at 6 months and were close to baseline at the 24-month measurement. Emotional function starting from a low baseline recovered to baseline by month 12. Cognitive and social function had slow recovery on follow-up. Fatigue, diarrhea, dyspnea, and sleep disturbance were symptoms persistent at 6-month follow-up, improving later on in survivors.

Conclusions

Survivors after CRS and HIPEC have postoperative quality of life similar to preoperatively, with most of the reduced elements recovering after 6–12 months. We conclude that reduced quality of life of patients after CRS and HIPEC should not be used as an argument to deny surgical therapy to these patients.
