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.

Closure of Iterative Laparotomy in Patients With Previous Mesh Reinforcement a Cohorts' Study. Short-Term Results.

Purpose: Due to extension of prophylactic mesh indications use will become more common to find patients receiving an iterative laparotomy (IL) over a previous reinforced abdominal wall. The aim of this study was to analyze outcomes after IL in patients with previous mesh reinforcement. Methods: This study was a prospective secondary analysis of midline laparotomy closure performed from July 2017 to July 2018 registered in PHACPA study (NCT02658955). IL were included and surgery characteristics and outcomes analyzed. We compared two groups: with (PreM) or without previous prophylactic onlay mesh reinforcement (PreS) Subgroups' analysis, risk factors for complications and survival free hernia analysis were performed. Results: 121 IL were analyzed. Only obesity was associated with higher SSO (OR 2.6; CI 95% 1.02-6.90; p = 0.04) There were 15 incisional hernias (IH) (14.4%). Group with previous mesh reinforcement (pre M) had a higher statistically significative incidence of IH (OR = 1.21; CI 95% 1.05-1.39; p = 0.015). Use of slowly absorbable suture (OR = 0.74; CI 95% 0.60-0.91; p = 0.001), USP 2/0 suture (OR, 0.31; 95% CI, 0.10-0.94; p = 0.033), and small bites technique (OR = 0.81; CI 95% 0.72-0.90; p = 0.011) were associated with less IH. Conclusion: IL has a high percentage of complications and IH. In case of IL without previous reinforcement, a mesh can help to reduce IH. Our data cannot clearly support any technique to close an IL with previous mesh.

Long-term follow-up of prophylactic mesh reinforcement after emergency laparotomy. A retrospective controlled study.

BACKGROUND: Prevention of incisional hernias with a prophylactic mesh in emergency surgery is controversial. The present study aimed to analyze the long-term results of prophylactic mesh used for preventing incisional hernia after emergency midline laparotomies. METHODS: This study was a registered (NCT04578561) retrospective analysis of patients who underwent an emergency midline laparotomy between January 2009 and July 2010 with a follow-up period of longer than 2 years. Long-term outcomes and risk factors for the development of incisional hernias between patients who received a prophylactic reinforcement mesh (Group M) and suture (Group S) were compared. RESULTS: From an initial 266 emergency midline laparotomies, 187 patients were included. The median follow-up time was 64.4 months (SD 35). Both groups had similar characteristics, except for a higher rate of previous operations (62 vs. 43.2%; P = 0.01) and operation due to a revision laparotomy (32.5 vs.13%; P = 0.02) in the M group. During follow-up, 29.9% of patients developed an incisional hernia (Group S 36.6% vs. Group M 14.3%; P = 0.002). Chronic mesh infections were diagnosed in 2 patients, but no mesh explants were needed, and no patient in the M group developed chronic pain. Long-term risk factors for incisional hernia were as follows: smoking (HR = 2.47; 95% CI 1.318-4.624; P = 0.05), contaminated surgery (HR = 2.98; 95% CI 1.142-7.8; P = 0.02), surgical site infection (SSI; HR = 3.83; 95% CI 1.86-7.86; P = 0.001), and no use of prophylactic mesh (HR = 5.09; 95% CI 2.1-12.2; P = 0.001). CONCLUSION: Incidence of incisional hernias after emergency midline laparotomies is high and increases with time. High-risk patients, contaminated surgery, and surgical site infection (SSI) benefit from mesh reinforcement. Prophylactic mesh use is safe and feasible in emergencies with a low long-term complication rate. TRIAL REGISTRATION: NCT04578561. www.clinicaltrials.gov.

Caecal volvulus and jejunostomy: challenging diagnostic.

Caecal volvulus represent the 20-40% of colonic volvulus, being the second most frequent localization. It causes intestinal occlusion symptomatology (nausea, vomiting, abdominal distension). We present a case of 45-year-old women with feeding jejunostomy tube due to connatal anoxia. She arrives at A&E after 12 h of vomits and abdominal pain. The CT scan shows a small intestine dilation that suggested a small intestine volvulus. A laparotomy is performed showing a caecal volvulus, so ileo-cequectomy with primary anastomosis is performed. After several complications, she was discharged after 60 days of hospital stay. Caecal volvulus can be challenging to diagnose by clinic, because it can be hardly differenced from other intestinal occlusion causes. CT scan can be useful to reach the diagnostic and see signs of tissue suffering. In contrast with sigma volvulus, endoscopic treatment has not shown any benefit to solve it.

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.

Incidence of Incisional Hernia After Emergency Subcostal Unilateral Laparotomy: Does Augmentation Prophylaxis Play a Role?

BACKGROUND: Few data are available about the frequency of incisional hernia in an emergency subcostal laparotomy. Our objective is to analyze the incidence of incisional hernia after emergency subcostal laparotomy and evaluate if prophylactic mesh could help prevent it. METHODS: This study is a monocentric retrospective analysis following STROBE guideline statements of all patients who underwent an emergency subcostal laparotomy between January 2011 and July 2017 in our University Hospital. We compared complications and incidence of incisional hernia between patients who received sutures (Group S; N = 203) and patients with prophylactic onlay mesh (Group M; N = 80). A multivariate risk factor analysis of incisional hernia was performed. An incisional hernia-estimated risk calculator equation was created. RESULTS: A total of 283 patients were analyzed. There were 80 patients in Group M and 203 in Group S. In short-term outcomes, length of surgery (213 ± 115 min vs 165 ± 73.3 min, P = 0.001) and hospital stay (16.4 ± 18.7 vs 11.6 days ± 13.4, P = 0.038) were longer in Group M. Long-term follow-up was conducted in 207 patients with a mean follow-up time of 39.3 ± 23 months. Incisional hernia was detected in 29 (19.1%) patients in Group S but in only two (3.8%) patients in Group M (P = 0.008). In the multivariate analysis, a risk factor analysis included wound infection (4.91 HR (2.12-11.4); P < 0.001), previous hernia repair (2.86 HR (1.24-6.61); P = 0.014), and shock (2.64 HR (1.01-6.93); P = 0.048). CONCLUSIONS: The incidence of incisional hernia after emergency subcostal laparotomy is high. Risk factors are wound infection, shock, and previous hernia surgery. The use of prophylactic mesh augmentation was safe and reduced the incidence of incisional hernia.
