Clinical Study on Assessment of Post-Surgical Complications According to Clavien–Dindo Classification after Major Abdominal Surgery
Aims and Objectives: Surgical complications occur in every surgical department. The absence of a definition and a widely accepted ranking system to classify surgical complications has hampered proper interpretation of the surgical outcome. This study aimed to define a simple and reproducible classification of complications following abdominal surgery based on a therapy-oriented severity grading system and to validate the Clavien–Dindo grades and categorize complications in elective major abdominal surgeries. Materials and Methods: This is a prospective study of 80 patients, who were diagnosed and admitted for major elective abdominal surgery in KIMS hospital, Hubli, from December 2012 to May 2014. Patients underwent definitive treatment. Data related to the objectives of the study were collected and post-operative complications were classified according to Clavien–Dindo grades and managed. Results: Ages between 30 and 39 years were the most common in our present study; there were 46 male patients and 34 female patients. Of 80 cases, 24 cases were cholelithiasis cases (predominate group) among which 17 were free of complications and 7 developed complications, 21.25% developed wound complications in the form of superficial surgical site infection followed by basal atelectasis (18.75%). 46 cases (57.5%) had complications in their post-operative course, among which Grade 1 constitutes 25 cases (31.25%), Grade 2 constitutes 12 cases (15%), Grade 3 A constitutes 2 cases (2.5%), Grade 3 B constitutes 2 cases (2.5%), Grade 4 A constitutes 1 case (1.25%), Grade 4 B constitutes 1 case (1.25%), and Grade 5 constitutes 3 cases (3.75%), and rest of 34 cases (42.5%) were free of complications and had normal post-operative course. In our study, Grade 1 complications were the most common complications. Conclusion: We conclude that the Clavien–Dindo classification is based on the therapeutic consequences of complications constitutes a simple, objective, and reproducible approach for comprehensive surgical outcome assessment. In this study, Clavien–Dindo Grade 1 complication is the most common complication.
