[Comparison of the results of laparotomy and laparoscopic surgery in patients with Crohn's disease]. / A nyitott és minimálisan invazív beavatkozások eredményeinek összehasonlítása Crohn-betegségben.

INTRODUCTION: Crohn's disease is an inflammatory bowel disease which may affect different parts of the gastrointestinal tract. AIM: To compare retrospectively the results of laparotomy and laparoscopic surgery performed in patients with Crohn's disease between January 1, 2005 and October 31, 2012 in the Department of Surgery, University of Szeged, Hungary. METHOD: Patients were divided into two groups based on the types of surgery; 103 patients underwent laparotomy and 30 patients had laparoscopic surgery programmed. 22 patients had 24 primary acute interventions. RESULTS: The mean age was significantly lower in the laparoscopic surgery group (p = 0.042). The laparoscopic ileocecal resections have been found significantly shorter than laparotomies (p = 0.033). When ileocecal resection was performed the operation time was significantly longer (p = 0.033) while hospitalization time (p = 0.025) and intensive care unit treatment time (p<0.001) were shorter and the bowel passage also started earlier in the laparoscopic group as compared to the laparotomy group. CONCLUSIONS: Laparoscopic surgery results in smaller surgical trauma, better cosmetic outcome, shorter hospitalization time and not higher complication- and morbidity-rate as well as shorter operation time in certain cases. However, it requires more qualified surgical team and the operation expenses are higher.

Design and validation of an assessment tool for open surgical procedures.

BACKGROUND: Laparoscopy is currently the gold standard for cholecystectomy. Recent literature suggests surgical trainees have limited exposure to open cholecystectomy, which may result in suboptimal performance in the event of conversion. Furthermore, most training and assessment models are designed for laparoscopic cholecystectomy, with limited opportunities for open simulator training. The present study's purpose was to design an inexpensive model for open cholecystectomy and to validate a performance assessment tool. METHODS: The simulator comprises a porcine liver and gallbladder in a mock human abdomen with silicon skin. The assessment tool utilizes inexpensive infrared (IR) cameras to provide tracking of participant hand motions. Eleven novice general surgery trainees (<20 cholecystectomies) and five expert surgeons (>100 cholecystectomies) completed an open cholecystectomy using the simulator. Procedures were recorded and assessed by a blinded evaluator using a global rating scale. Tracking data analysis was based on number of movements and total path length. RESULTS: Novices (t = 36.18 min) completed the procedure significantly slower than did experts (t = 19.53 min) (Mann-Whitney test U = 20, p < 0.05) and had significantly more hand movements (Mann-Whitney test U = 20, p < 0.05). Analysis of the total global rating scale scores showed a significant difference between novice (14/35) and expert (24/35) performance in all categories (Mann-Whitney test U = 58, p < 0.05). CONCLUSION: The present model presents a realistic, low-cost tool for training and assessment of procedural skills in open cholecystectomy. The study demonstrated the validity of the IR tracking device as an objective assessment tool for open surgical skills training. Future training should incorporate this low-cost, highly effective training device into surgical curricula.

Evolution of surgical management of early-stage endometrial cancer.

OBJECTIVE: We sought to examine the evolution of surgical care for early-stage endometrial cancers and factors affecting use of laparoscopy. STUDY DESIGN: Women with surgically managed early-stage endometrial cancer were divided into 2 groups corresponding to before and after addition of faculty with formal fellowship training in laparoscopic staging and access to a robotic surgery platform. RESULTS: In all, 502 women were identified. Laparoscopic management increased from 24-69% between time periods (P < .0001). Performance of comprehensive surgical staging, and lymph node counts, increased (P < .0001) despite an increase in median body mass index (P = .001). A traditional "straight stick" technique was performed in 72% of laparoscopic cases during the later period. Laparoscopy patients had lower estimated blood losses and shorter hospital stays (each P < .0001) compared to laparotomy patients. CONCLUSION: Addition of faculty with formal fellowship training in laparoscopic staging and access to a robotic surgery platform shifted management of early-stage endometrial cancer toward laparoscopy.

Spill your guts! Perceptions of Trauma Association of Canada member surgeons regarding the open abdomen and the abdominal compartment syndrome.

BACKGROUND: To survey surgeon opinion regarding the management of the open abdomen (OA) and abdominal compartment syndrome (ACS) to assess current practice and direct future prospective clinical studies. METHODS: Opinions of self-designated trauma, general, pediatric, and vascular surgeons belonging to the Trauma Association of Canada (TAC), were surveyed through a mixed-mode (mail and Web based) questionnaire. RESULTS: Among 102 eligible candidates, 86 (84%) responded; 83% did regular trauma call, 45% regular critical care call being a separate call 79% of the time; 79% worked in centers serving >500,000 people; the median year of practice entry was 1997. There was no standard definition of what constituted an "open abdomen", preferred time for re-operation, or preferred method for alternate fascial closure, although 90% reported having not closing the fascia after a trauma laparotomy. Being "physically unable" was reported as an indication twice as often as objective measures of airway or bladder pressures. The decision to proceed with OA was reported as rarely or never being made preoperatively by 78% of respondents. None reported an institutional policy regarding OA. Eighty-four percent reported (re)opening an abdomen for primary ACS, 46% for secondary ACS, 28% for tertiary ACS. Self-assessed familiarity for the ACS was 6/7 on a Likert scale. Physical examination was reported as a diagnostic criterion for ACS by 66%, and used to screen by 21% of respondents. CONCLUSIONS: There is no consensus regarding definition, functional indications, or management of an open abdomen in the perceptions of Canadian trauma providers despite a high self reported level of familiarity with the abdominal compartment syndrome. This is an area of practice with potential and requirements for further multi-center study.
