Kingsnorth's modified score as predictor of complications in open inguinal hernia repair.

PURPOSE: This study aims to analyse the postoperative complications (30 days) on unilateral primary inguinal hernia repair and prove their correlation with the preoperative modified scoring system of Kingsnorth (KN). METHODS: Prospective study design collecting data from patients who underwent surgery for unilateral primary inguinal hernia in a University Hospital. The data were collected in the National Inguinal Hernia Registry (EVEREG). A statistical analysis to assess the association between the presence of postoperative complications and the preoperative and intraoperative variables was performed. The patients were classified depending on their KN score. Surgical complications and their relationship with the classification were specifically analysed. Study design was performed following STROBE statements. RESULTS: The sample included 403 patients who met the inclusion criteria from which 62 (15.3%) subjects presented postoperative complications. The variables that presented a statistically significant relationship with the appearance of complications were a KN score of 5-8 (OR 2.7; 95% CI 1.07-4.82; P = 0.03) and the involvement of a member of the abdominal wall surgery unit in the procedure (OR 0.28; 95% CI 0.08-0.92; P = 0.03). The KN score correlated with a longer duration of surgery (Pearson's correlation 0.291; P < 0.0001). CONCLUSION: The KN classification can predict the onset of surgical wound complications on patients who undergo a primary unilateral inguinal hernia surgery. A KN score of 5-8 has a higher probability of wound complications. When surgery is performed by the abdominal wall surgery unit, the chances of postoperative complications decrease.

Parestomal hernia repair. Prospective observational study based on the Spanish Registry of Incisional Hernia (EVEREG).

INTRODUCTION: The results of parastomal hernia (PH) repair based on data from registries are scarce. The objective of this work is to analyze the data collected on PH in the National Registry of Incisional Hernia (EVEREG) and thus evaluate current practices and results in PH repair. METHODS: Data from the PH cohort recorded in the period from July 2012 to June 2018 are analyzed. Complications, recurrences and associated factors of the entire PH cohort are analyzed, regardless of the type of stoma they are associated with. Subsequently, the same PH group analysis was performed in relation to a colostomy (larger group). RESULTS: 353 PH were studied. Of these, 259 (73%) were PH in the context of a terminal colostomy, 74 (21%) in the context of a terminal ileostomy, and 20 (6%) in the context of a ureteroileostomy (Bricker). The global mean age was 68.7 ± 11.1 years and 135 (38%) patients were female. The open approach and elective surgery were predominant (78% and 92% respectively); 99% were repaired with a non-absorbable synthetic mesh. Global postoperative complications were high (30.6%). As well as, the global recurrence (27.5%) after a mean follow-up of 9.4 months. CONCLUSIONS: PH repair is infrequent. PH surgery seems to be associated with a high percentage of postoperative complications and recurrence.

Small bites technique for midline laparotomy closure: From theory to practice: Still a long way to go.

BACKGROUND: The closure technique of the abdominal wall is a key factor in the development of incisional hernia. Our aim was to implement a protocol for closure of median laparotomy, to evaluate the grade of implementation, as well as to assess the results and safety of the technique. METHODS: A series of formative activities to implement the small bites technique for closure of median laparotomy in elective operations were designed. After 1 year, a survey was conducted on knowledge and use of the technique. Prospective compilation of data of all median laparotomy in elective operations and their follow-up was done for 1 year. The incidence of incisional hernia depending on the fulfilment of the protocol was compared. RESULTS: A total of 74 surgeons participated in the activities. All the participants accomplished the technique perceiving low difficulty (1.9/10). After 1 year, 44 surgeons answered the survey; 95% stated that they knew the small bites technique and used it always or almost always, but only 52% performed the calculation of the suture length and the incision length ratio. A total of 114 median laparotomy in elective operations were analyzed; among them, 30.7% were closed with small bites presenting a lower frequency of incisional hernia and burst abdomen (small bites 3.6% vs large bites 12.1%; odds ratio 1.30; confidence interval, 0.992--1.711; P = .20). CONCLUSION: The measures were effective for learning, but education alone was not enough to implement the technique in the real scenario. Small bites technique is reproducible, has no risks, and provides low incidence of incisional hernia. More incentives and actions are needed to improve laparotomy closure.

Reparación de la hernia paraestomal. Estudio observacional prospectivo basado en el Registro Español de Hernia Incisional (EVEREG) / Parestomal hernia repair. Prospective observational study based on the Spanish Registry of Incisional Hernia (EVEREG)

Introducción: Los resultados de la reparación de la hernia paraestomal (HP) basados en datos provenientes de registros son escasos. El objetivo del presente trabajo es analizar los datos recogidos sobre la HP en el Registro Nacional de Hernia Incisional (EVEREG) y así evaluar las prácticas actuales y resultados en la reparación de una HP. Métodos: Se analizan los datos de la cohorte de HP registradas en el período desde julio de 2012 hasta junio de 2018. Se analizan las complicaciones, recidivas y factores asociados a ellas de la cohorte completa de HP, independientemente del tipo de estoma al que se asocian. Posteriormente, se realiza el mismo análisis del grupo de HP con relación a una colostomía (grupo más numeroso). Resultados: Se estudiaron 353 HP. De estas, 259 (73%) fueron HP en el contexto de una colostomía terminal, 74 (21%) en el de una ileostomía terminal y 20 (6%) en el de una ureteroileostomía (Bricker). La edad media global fue de 68,7±11,1 años y 135 (38%) pacientes fueron del sexo femenino. El abordaje abierto y la cirugía electiva fueron predominantes (78% y 92%, respectivamente). El 99% se reparó con una malla sintética no absorbible. Las complicaciones postoperatorias globales fueron altas (30,6%), así como la recurrencia global (27,5%) tras un seguimiento medio de 9,4 meses. Conclusiones: La reparación de la HP es poco frecuente comparada con el conjunto de reparaciones de la hernia incisional. La cirugía de la HP parece relacionarse con un porcentaje elevado de complicaciones postoperatorias y recidiva. (AU)
