Influence of learning curve and surgeon experience on postoperative pain after laparoscopic treatment of inguinal hernias.

INTRODUCTION: Laparoscopic approach for inguinal hernia offers considerable advantages. Several risk factors for postoperative pain have been investigated, but few articles can be found about learning curve and surgeon's influence on postoperative pain after inguinal herniorrhaphy. PATIENTS AND METHODS: A prospective study was conducted including 105 patients. Surgical procedures were performed by two general surgeons performing TAPP procedure. Follow up was realized at one and three months after surgery. RESULTS: Majority of investigated data were without significant differences. In case of the Senior Surgeon we registered higher SEI (surgeon experience index), increased proportion of bilateral inguinal hernias (P = 0.0309) and higher percentage of longer surgical procedures (P = 0.0309). Meantime in case of the Junior Surgeon we recorded operations with intermediate duration (P = 0.0232) in a greater manner. During the follow up period, similar incidence of pain senzation was remarked among patients, without statistical significance. CONCLUSION: With adequate learning program and supervision TAPP procedure can be a safe technique when performed by young specialist too, presenting similar postoperative results with those of experienced surgeons.

Influence of Mesh Fixation on the Development of Postoperative Pain after Laparoscopic Inguinal Hernia Repair: A Single Surgeon Experience.

OBJECTIVE: Primary aim of the present article was to determine the relationship between mesh fixation methods and the occurrence of postoperative pain after laparoscopic inguinal hernia repair. Materials and Methods: 101 patients diagnosed with inguinal hernia benefited from elective laparoscopic treatment of the abdominal wall defect. Follow up was realized at one and three months after surgical intervention. The followed details contained clinical, surgical and pain-related data. Results: Multivariable analysis resulted young adults (OR=4.226; p=0.0467), recurrent hernia (OR=4.862; p=0.0415) and use of fixation requiring surgical mesh (OR=4.226; p=0.0467) as significant risk factors in the development of chronic postoperative pain. During the follow up period, patients who benefitted of mesh fixation complained about significantly higher pain sensation (pain index at one month: SG=10.27; CG=5.07; p=0.0080; pain index at three months: SG=5.02; CG=1.42; p=0.0406). Concerning chronic postoperative pain syndrome, six patients from SG (12.76%) and only a single patient from CG complained after three months about pain index greater than 18.5 points, concluding that mesh fixation significantly increases the possibility of chronic postoperative pain syndrome (p=0.0455). Conclusions: Mesh fixation methods during laparoscopic inguinal hernia repair seem to contribute to the development of chronic postoperative pain. Avoiding traumatizing mesh fixation methods could be a suitable option for surgeons.

Elderly Patients with Colorectal Cancer - A Predisposed Category for Postoperative Complications.

Introduction: Colorectal cancer (CRC) is among the leading causes of cancer-related deaths around the world. Elderly patients are often considered as a high-risk category of patients, predisposed for postoperative complications. Materials and methods: 138 patients aged over 75 years and diagnosed with colorectal cancer were retrospectively reviewed. Patients were divided in two groups, as follows: Study Group including patients who developed postoperative complications, and Control Group including patients without problems in the postoperative period. There were compared clinical, preoperative, surgical, postoperative and oncological data. The aim of study was to determine possible risk factors for short-term postoperative complications and analyze of the influence of postoperative complications on survival. Results: Risk factors as male gender, obesity, heart failure, diabetes type II, severe anemia, low total protein level, ASA III-IV classification, emergency surgery, prolonged surgical intervention, increased intraoperative blood loss, prolonged hospital stay, distal localization of tumors, TNM stages III-IV, surgery for digestive cancer and non-cancerous major abdominal surgery in the medical history were identified. Conclusion: The surgical treatment of colorectal cancer in the aging population still remains a challenge, these category of patients should benefit of special attention in order to ensure a chance to minimize or avoid these complications.
