Computer-generated structured electronic medical records are preferable to conventional medical records for patients with acute abdominal pain - a prospective, double-blinded study.

OBJECTIVES: Structured medical records improve readability and ensure the inclusion of information necessary for correct diagnosis and treatment. This is the first study to assess the quality of computer-generated structured medical records by comparing them to conventional medical records on patients with acute abdominal pain. MATERIALS AND METHODS: A prospective double-blinded study was conducted in a tertiary referral center emergency department between January 2018 and June 2018. Patients were examined by emergency department physicians and by experience and inexperienced researcher. The researchers used a new electronical medical records system, which gathered data during the examination and the system generate structured medical records containing natural language. Conventional medical records dictated by physician and computer-generated medical records were compared by a group of independent clinicians. RESULTS: Ninety-nine patients were included. The overall quality of the computer-generated medical records was better than the quality of conventional human-generated medical records - the structure was similar or better in 99% of cases and the readability was similar or better in 86% of cases, p < 0.001. The quality of medical history, current illness, and findings of physical examinations were likewise better with the computer-generated recording. The results were similar when patients were examined by experienced or inexperienced researcher using the computer-generated recording. DISCUSSION: The quality of computer-generated structured medical records was superior to that of conventional medical records. The quality remained similar regardless of the researcher's level of experience. The system allows automatic risk scoring and easy access for quality control of patient care. We therefore consider that it would be useful in wider practice.

Mortality Related to Appendectomy; a Population Based Analysis over Two Decades in Finland.

OBJECT: To define the mortality rate of appendectomy patients and appendectomy-related risk factors. BACKGROUND: Appendectomy has been considered as a safe operation and negative appendectomies acceptable in order to avoid perforations. There are few publications on appendectomy-related mortality. Removal of a normal appendix has been suggested to be related to a higher mortality rate versus removal of an inflamed appendix. METHODS: Data on all appendectomy patients between 1990 and 2010 in Finland were retrieved from the Discharge Register of the National Institute for Health and Welfare and combined with data from the Death Certificate Register of Statistics Finland. Thirty-day mortality was identified and compared with overall mortality. Detailed information from death certificates of patients dying within 30-day post-surgery was collected and analyzed. RESULTS: Over the study period, the thirty-day post-appendectomy mortality rate was 2.1/1000. Increased mortality was found in patients over 60 years of age. Negative appendectomy and complicated appendicitis were related to mortality. The negative appendectomy rate was higher in patients older than 40 years of age. During the study period, both mortality and the rate of negative appendectomies decreased, while the rate of laparoscopic appendectomies increased. CONCLUSIONS: Post-appendectomy mortality is related to both negative appendectomies and complicated appendicitis. Diagnostic accuracy is fundamental in the care of patients with acute appendicitis, especially in the elderly. Improved diagnostic accuracy may have reduced mortality over the last two decades in Finland.

Modified approach for endoscopic harvest of the latissimus dorsi free flap with CO2 insufflation and standard laparoscopic equipment.

OBJECTIVE: The latissimus dorsi (LD) muscle flap is frequently used for free tissue transfer to reconstruct large defects of the extremities. As a free flap, the LD also can be harvested as a muscle-sparing flap (MS-LD), preserving the innervation and insertion of the remaining muscle. Conventional harvesting of the LD flap, however, results in a long scar on the lateral back. Harvesting using an endoscopic approach minimizes donor site morbidity. We present our modified endoscopic technique with CO2 insufflation and standard endoscopic instruments for harvesting the LD or MS-LD muscle flap. PATIENTS AND METHODS: Ten patients (mean age 43 years, range 22-66) underwent endoscopically harvested LD or MS-LD free-flap reconstruction for upper and lower extremity defects. Harvesting required only a short (3-5 cm) incision in the axilla for dissection of the vascular pedicle and the motor nerve, and the remainder of the dissection was performed endoscopically with CO2 insufflation. Dissection was achieved through three of four 5-mm ports and 30° view angle optics. RESULTS: Six of the flaps were MS-LD flaps. The largest flap size was 18 × 16 cm. Mean flap harvest time was 164 min (range 105-270 min). One total flap was lost 3 days postoperatively due to anastomotic thrombosis in a trauma patient who was later diagnosed with hypercoagulopathy. No donor site scar or wound complications were observed during the follow-up (20.1 months). CONCLUSIONS: Endoscopic harvesting of an LD muscle free flap with CO2 insufflation and standard laparoscopic equipment is a feasible option for free-flap reconstruction. © 2016 Wiley Periodicals, Inc.

Severe Complications of Laparoscopic and Conventional Appendectomy Reported to the Finnish Patient Insurance Centre.

BACKGROUND: Appendectomy is considered a safe operation, the related complications being minor. Negative exploration is an accepted procedure to avoid complications of appendicitis. Treatment with antibiotics is under debate as a primary treatment for appendicitis. The aim of this study was to collect and analyze detailed information on complications and morbidity related to appendectomy using the information of the nationwide Patient Insurance Association (PIA) database and to study the incidence of patient claims and compensated injuries related to appendectomy in Finland. METHODS: Patients' claims from 1990 to 2010 were collected from the PIA register. Complications were classified using the accordion severity grading system. Severe complications were selected for more detailed analyses. Laparoscopic and open surgeries were compared. Factors related to compensated claims were assessed. For statistical analysis, Fisher's exact test, logistic multivariate regression, and the Mann-Kendall function were used. RESULTS: Appendectomy complications leading to a patient insurance claim in Finland are rare (0.2 %). The rate of patients' claims after laparoscopic surgery was higher than after open surgery (p < 0.001), but the rate of compensated claims was equal. During the study period, complications after laparoscopic procedures more often led to additional surgery or organ failure (p = 0.03). Of the patients with a compensated injury, only 57 % had appendicitis. Preoperative computed tomography was used in only 6 % of these cases. CONCLUSIONS: Patient injuries and claims regarding severe complications after appendectomy are rare. The complications related to laparoscopic appendectomy were more severe than those of open surgery.

Continuous absorbable intradermal sutures yield better cosmetic results than nonabsorbable interrupted sutures in open appendectomy wounds: a prospective, randomized trial.

BACKGROUND: Acute appendicitis is the most common reason for abdominal surgery in young adults and children. Open appendectomy is still the treatment often chosen because it is simple, safe, and effective. Our aim was to study whether cosmetic results of appendectomy wounds are better after using continuous absorbable intradermal (A) sutures compared with wound closure with interrupted nonabsorbable (NA) sutures. METHODS: A total of 206 adult patients with clinically suspected appendicitis were allocated to the study and prospectively randomized into two wound-closure groups: the interrupted NA suture group and the A suture group. Of these, 193 patients with sufficient data were invited to the outpatient clinic for cosmetic analysis. Cosmetic results were evaluated after a median of 14 months. For subjective scar assessment, the Vancouver scar scale, the patient and observer scar assessment scale (POSAS), and a visual analog scale (VAS) were used. Objective evaluation was carried out by measuring surface area, average width, and estimated concentration change (ECC) of hemoglobin and melanin in the scar using spectrocutometry. For statistical analyses we used the Mann-Whitney test and Student's t test. RESULTS: Both objective and subjective analyses showed better cosmetic results for absorbable intradermal suturing. The difference between the two groups was statistically significant as regards POSAS in both patient (p = 0.032) and observer scales (p = 0.001), and VAS (p = 0.002). Scar surface area was significantly smaller in group A than in group NA (p = 0.002). ECC measurements showed higher values for melanin in group NA than in group A (p = 0.034). CONCLUSION: Continuous intradermal absorbable suturing yields a better cosmetic result than interrupted nonabsorbable suturing in lower abdominal transverse appendectomy.

Short learning curve in transition from laparoscopic to robotic-assisted rectal cancer surgery: a prospective study from a Finnish Tertiary Referral Centre.

The narrow pelvis causes special challenges in surgery, and robotic-assisted surgery has been proven beneficial in these circumstances. While robotic surgery has some specific advantages in rectal cancer surgery, there is still limited evidence of the learning curve of the technique involved. The aim here was to study the transition from laparoscopic to robotic-assisted surgery among experienced laparoscopic surgeons. The data for this study were collected from a prospectively compiled register that includes patients operated on by the Da Vinci Xi robot in Tampere University Hospital. Each consecutive rectal cancer patient was included. The information on the surgical and oncological outcomes was analysed. The learning curve was assessed using cumulative sum (CUSUM) analysis. CUSUM already demonstrated an overall positively sloped curve at the beginning of the study, with neither the conversion rate nor morbidity reaching unacceptable thresholds. Conversions (4%) and postoperative complications (Clavien-Dindo III-IV 15%, no intraoperative complications) were rare. One patient died within one month and the death was not procedure-associated. While surgical and oncological outcomes were similar among all surgeons, the console times showed a decreasing trend and were shorter among those with more experience in laparoscopic rectal cancer surgery. Robotic-assisted rectal cancer surgery can be safely adapted by experienced laparoscopic colorectal surgeons.

Preoperative computed tomography is poor in detecting tumors of the appendix among patients with acute appendicitis: A cohort study of 5,224 appendectomies.

BACKGROUND: Neoplastic processes are among the known etiologies for acute appendicitis. While conservative treatment with antibiotics alone has been proposed as a treatment for uncomplicated appendicitis, the presence of tumors should be excluded when offering patients this option. The aim of this study was to assess the accuracy of computed tomography (CT) in detecting appendiceal tumors. METHOD: Consecutive patients operated on for acute appendicitis between January 2007 and October 3, 2018, in our university hospital were included. Whenever appendiceal tumor was histopathologically confirmed, CT interpretations and surgical reports were carefully reviewed. All CT scans were reanalyzed by consultant body radiologists. Discrepancies between the preliminary and final radiological interpretations were noted. RESULTS: A total of 5,224 patients underwent appendectomy, of whom 4,766 had histopathologically confirmed acute appendicitis. Eighty-four patients (median, 61 (13-89) years; 54% female) were diagnosed with appendiceal tumor. Fifty-two patients (62%) had uncomplicated appendicitis. Although incidence of tumors was associated with older age, tumors were found in all ages. The share of tumors increased from 1.7% to 3.0%/year during the study. The most common tumors were neuroendocrine tumors (n = 33), low-grade appendiceal mucinous neoplasms (n = 14), and adenocarcinomas (n = 11). Sixty-one patients (73%) underwent preoperative CT. Computed tomography interpretation during on-call hours suspected tumor in only one case (3.4%) with invasive tumor, and in five cases (16%) with noninvasive tumor. CONCLUSION: Appendiceal tumors are possible findings in appendix specimens, and most patients had uncomplicated acute appendicitis. In light of findings we conclude that CT cannot be used to exclude neoplastic etiology underlying acute appendicitis. LEVEL OF EVIDENCE: Diagnostic, level IV.
