Phenobarbital in super-refractory status epilepticus (PIRATE): A retrospective, multicenter analysis.

OBJECTIVE: Super-refractory status epilepticus (SRSE) is an enduring or recurring SE after 24 h or more of general anesthesia. This study aimed to evaluate the efficacy and safety of phenobarbital (PB) for the treatment of SRSE. METHODS: This retrospective, multicenter study included neurointensive care unit (NICU) patients with SRSE treated with PB between September 2015 and September 2020 from six participating centers of the Initiative of German NeuroIntensive Trial Engagement (IGNITE) to evaluate the efficacy and safety of PB treatment for SRSE. The primary outcome measure was seizure termination. In addition, we evaluated maximum reached serum levels, treatment duration, and clinical complications using a multivariate generalized linear model. RESULTS: Ninety-one patients were included (45.1% female). Seizure termination was achieved in 54 patients (59.3%). Increasing serum levels of PB were associated with successful seizure control (per µg/mL: adjusted odds ratio [adj.OR] = 1.1, 95% confidence interval [CI] 1.0-1.2, p < .01). The median length of treatment in the NICU was 33.7 [23.2-56.6] days across groups. Clinical complications occurred in 89% (n = 81) of patients and included ICU-acquired infections, hypotension requiring catecholamine therapy, and anaphylactic shock. There was no association between clinical complications and treatment outcome or in-hospital mortality. The overall average modified Rankin scale (mRS) at discharge from the NICU was 5 ± 1. Six patients (6.6%) reached mRS ≤3, of whom five were successfully treated with PB. In-hospital mortality was significantly higher in patients in whom seizure control could not be achieved. SIGNIFICANCE: We observed a high rate in attainment of seizure control in patients treated with PB. Success of treatment correlated with higher dosing and serum levels. However, as one would expect in a cohort of critically ill patients with prolonged NICU treatment, the rate of favorable clinical outcome at discharge from the NICU remained extremely low. Further prospective studies evaluating long-term clinical outcome of PB treatment as well as an earlier use of PB at higher doses would be of value.

Is prophylactic mesh closure effective to decrease the incidence of incisional hernia after laparotomy in colorectal surgery?

BACKGROUND: few studies have studied prophylactic mesh closure after laparotomy for colorectal surgery. METHODS: a retrospective cohort study was performed to compare patients with and without prophylactic mesh closure after open colorectal surgery. RESULTS: 309 patients were included from January 2014 to December 2016. Prophylactic mesh closure was performed in 98 patients (31.7%). After a mean follow-up of 21.7 months, incisional hernia was developed in 9 and 54 patients in the group with and without mesh respectively (9.2% vs. 25.7%, OR = 0.3, p = 0.001). In the multivariate Cox model prophylactic mesh closure was associated with a protective effect on incisional hernia development with a Hazard Ratio of 0.46 (p = 0.033). Surgical site infection was more frequent in the mesh group (19.4% vs. 9.5%, OR = 2.3, p = 0.015). CONCLUSIONS: prophylactic mesh closure is effective to decrease the incidence of incisional hernia after colorectal surgery.

Trocar-site incisional hernia after laparoscopic colorectal surgery: a significant problem? Incidence and risk factors from a single-center cohort.

BACKGROUND: Trocar-site incisional hernia (TSIH) after laparoscopic surgery has been scarcely studied. TSIH incidence and risk factors have never been properly studied for laparoscopic colorectal surgery. METHODS: A retrospective analytic study in a tertiary hospital was performed including patients who underwent elective laparoscopic colorectal surgery between 2014 and 2016. Clinical and radiological TSIH were analyzed. RESULTS: 272 patients with a mean age of 70.7 years were included. 205 (75.4%) underwent surgery for a malignant disease. The most common procedure was right colectomy (108 patients, 39.7%). After a mean follow-up of 30.8 months 64 (23.5%) patients developed a TSIH. However, only 7 out of 64 (10.9%) patients with a TSIH underwent incisional hernia repair. That means that 2.6% of all the patients underwent TSIH repair. 44 (68.8%) patients had TSIH in the umbilical Hasson trocar. In the multivariate analysis, the existence of an umbilical Hasson trocar orifice was the only statistically significant risk factor for TSIH development. CONCLUSIONS: Incidence of TSIH was high, although few patients underwent incisional hernia repair. Most TSIH were observed in the umbilical Hasson trocar, which was the only risk factor for TSIH development in the multivariate analysis. Efforts should be addressed to avoid TSIH in the umbilical Hasson trocar.

Extraction-site incisional hernia after laparoscopic colorectal surgery: should we carry out a study about prophylactic mesh closure?

BACKGROUND: Prophylactic mesh closure has only scarcely been studied to avoid extraction-site incisional hernia after laparoscopic colorectal surgery. The aim was to analyze extraction-site incisional hernia incidence after laparoscopic colorectal surgery to assess if prophylactic mesh closure should be studied. METHODS: A retrospective analytic cohort study was conducted in patients who had undergone laparoscopic colorectal surgery with an extraction-site incision. Extraction-site incisional hernia was diagnosed during clinical examination or imaging. Risk factors for extraction-site incisional hernia were analyzed. RESULTS: Two hundred and twenty-five patients were included. More than 80% of the patients had a malignant disease. Ninety-two patients (40.9%) underwent right colectomy. Midline extraction-site incision was used in 86 (38.2%) patients. After a mean follow-up of 2.4 years, 39 (17.3%) patients developed an extraction-site incisional hernia. Midline extraction-site incision was associated with incisional hernia when compared to transverse and Pfannenstiel incision (39.5% vs. 3.6%, OR 17.5, p < 0.001). Surgery to repair an extraction-site incisional hernia was also more frequent in the group of patients with a midline incision (10.5% vs. 1.4%, OR 8.0, p = 0.002). In the multivariate analysis, incisional hernia was associated with body mass index, high blood pressure, and midline incision. CONCLUSIONS: Extraction-site incisional hernia was mainly related to midline incisions; therefore, midline incision should be avoided whenever possible. Studying prophylactic mesh closure for Pfannesnstiel or transverse incisions is needless, as these incisions have a low incisional hernia risk.

Safety and feasibility of cholecystectomy in octogenarians. Analysis of a single center series of 316 patients.

INTRODUCTION: Cholecystectomy is the treatment of choice for symptomatic cholelithiasis. However, outcomes for patients over 80years of age are not well studied. The primary aim of this study was to describe the safety and feasibility of cholecystectomy, including in the acute setting, in a cohort of patients≥80 years of age. MATERIAL AND METHODS: A retrospective study of patients aged≥80 years submitted to cholecystectomy at a single institution from January 2013 to January 2018 was performed. Severity of acute cholecystitis was graded according to the updated Tokyo Guidelines 18. Early cholecystectomy was defined as being performed within the first 48h after admission and delayed when performed beyond 48h of the admission. RESULTS: In total 316 patients underwent cholecystectomy. The indication was acute cholecystitis in 113 (36%) patients. Of the 316 patients 289 (92%) were attempted laparoscopically and 30 (10%) were converted to open. Major complications occurred in 44 patients (14%) and mortality rate was 4%. No bile duct injuries were observed. For those patients with mild or moderate acute cholecystitis (n = 103), there was no differences in outcomes when comparing early vs delayed surgery. CONCLUSION: Cholecystectomy in patients≥80 years of age is safe and feasible. Outcomes did not differ between early and delayed surgery for mild/moderate acute cholecystitis.
